Hydroxyapatite catalyzed hydrothermal liquefaction transforms food waste from an environmental liability to renewable fuel.

    Description: Food waste is an abundant and inexpensive resource for the production of renewable fuels. Biocrude yields obtained from hydrothermal liquefaction (HTL) of food waste can be boosted using hydroxyapatite (HAP) as an inexpensive and abundant catalyst. Combining HAP with an inexpensive homogeneous base increased biocrude yield from 14 ± 1 to 37 ± 3%, resulting in the recovery of 49 ± 2% of the energy contained in the food waste feed. Detailed product analysis revealed the importance of fatty-acid oligomerization during biocrude formation, highlighting the role of acid-base catalysts in promoting condensation reactions. Economic and environmental analysis found that the new technology has the potential to reduce US greenhouse gas emissions by 2.6% while producing renewable diesel with a minimum fuel selling price of $1.06/GGE. HAP can play a role in transforming food waste from a liability to a renewable fuel.

    Description: Sleep deprivation can impair human health and performance. Habitual total sleep time and homeostatic sleep response to sleep deprivation are quantitative traits in humans. Genetic loci for these traits have been identified in model organisms, but none of these potential animal models have a corresponding human genotype and phenotype. We have identified a mutation in a transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. Activity profiles and sleep recordings of transgenic mice carrying this mutation showed increased vigilance time and less sleep time than control mice in a zeitgeber time- and sleep deprivation-dependent manner. These mice represent a model of human sleep homeostasis that provides an opportunity to probe the effect of sleep on human physical and mental health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2884988/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2884988/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Ying -- Jones, Christopher R -- Fujiki, Nobuhiro -- Xu, Ying -- Guo, Bin -- Holder, Jimmy L Jr -- Rossner, Moritz J -- Nishino, Seiji -- Fu, Ying-Hui -- HL059596/HL/NHLBI NIH HHS/ -- MH074924/MH/NIMH NIH HHS/ -- R01 HL059596/HL/NHLBI NIH HHS/ -- R01 HL059596-09/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):866-70. doi: 10.1126/science.1174443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, University of California at San Francisco, Mission Bay, 1550 Fourth Street, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679812" target="_blank"〉PubMed〈/a〉

    Description: Ecological speciation occurs when ecologically based, divergent selection causes the evolution of reproductive isolation. There are many empirical examples of this process; however, there exists a poorly characterized stage during which the traits that distinguish species ecologically and reproductively segregate in a single population. By using a combination of genetic mapping, mate-choice experiments, field observations, and population genetics, we studied a butterfly population with a mimetic wing color polymorphism and found that the butterflies exhibited partial, color-based, assortative mate preference. These traits represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species. The association between behavior and recognition trait in a single population may enhance the probability of speciation and provides an example of the missing link between an interbreeding population and isolated species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Nicola L -- Hill, Ryan I -- Kapan, Durrell D -- Gilbert, Lawrence E -- Kronforst, Marcus R -- GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763-06/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):847-50. doi: 10.1126/science.1179141.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Arts and Sciences Center for Systems Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892982" target="_blank"〉PubMed〈/a〉

    Description: Children acquire their native language according to a well-defined time frame. Surprisingly, although children raised in bilingual environments have to learn roughly twice as much about language as their monolingual peers, the speed of acquisition is comparable in monolinguals and bilinguals. Here, we show that preverbal 12-month-old bilingual infants have become more flexible at learning speech structures than monolinguals. When given the opportunity to simultaneously learn two different regularities, bilingual infants learned both, whereas monolinguals learned only one of them. Hence, bilinguals may acquire two languages in the time in which monolinguals acquire one because they quickly become more flexible learners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kovacs, Agnes Melinda -- Mehler, Jacques -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):611-2. doi: 10.1126/science.1173947.

    Description: Throughout the history of mathematics, concepts of number and space have been tightly intertwined. We tested the hypothesis that cortical circuits for spatial attention contribute to mental arithmetic in humans. We trained a multivariate classifier algorithm to infer the direction of an eye movement, left or right, from the brain activation measured in the posterior parietal cortex. Without further training, the classifier then generalized to an arithmetic task. Its left versus right classification could be used to sort out subtraction versus addition trials, whether performed with symbols or with sets of dots. These findings are consistent with the suggestion that mental arithmetic co-opts parietal circuitry associated with spatial coding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knops, Andre -- Thirion, Bertrand -- Hubbard, Edward M -- Michel, Vincent -- Dehaene, Stanislas -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1583-5. doi: 10.1126/science.1171599.

    Description: Platelets play a critical role in the pathogenesis of malarial infections by encouraging the sequestration of infected red blood cells within the cerebral vasculature. But platelets also have well-established roles in innate protection against microbial infections. We found that purified human platelets killed Plasmodium falciparum parasites cultured in red blood cells. Inhibition of platelet function by aspirin and other platelet inhibitors abrogated the lethal effect human platelets exert on P. falciparum parasites. Likewise, platelet-deficient and aspirin-treated mice were more susceptible to death during erythrocytic infection with Plasmodium chabaudi. Both mouse and human platelets bind malarial-infected red cells and kill the parasite within. These results indicate a protective function for platelets in the early stages of erythrocytic infection distinct from their role in cerebral malaria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMorran, Brendan J -- Marshall, Vikki M -- de Graaf, Carolyn -- Drysdale, Karen E -- Shabbar, Meriam -- Smyth, Gordon K -- Corbin, Jason E -- Alexander, Warren S -- Foote, Simon J -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):797-800. doi: 10.1126/science.1166296.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Menzies Research Institute, University of Tasmania, Private Bag 23, Hobart, Tasmania 7000, Australia. brendan.mcmorran@utas.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197068" target="_blank"〉PubMed〈/a〉

    Description: Hepatitis delta virus (HDV) and cytoplasmic polyadenylation element-binding protein 3 (CPEB3) ribozymes form a family of self-cleaving RNAs characterized by a conserved nested double-pseudoknot and minimal sequence conservation. Secondary structure-based searches were used to identify sequences capable of forming this fold, and their self-cleavage activity was confirmed in vitro. Active sequences were uncovered in several marine organisms, two nematodes, an arthropod, a bacterium, and an insect virus, often in multiple sequence families and copies. Sequence searches based on identified ribozymes showed that plants, fungi, and a unicellular eukaryote also harbor the ribozymes. In Anopheles gambiae, the ribozymes were found differentially expressed and self-cleaved at basic developmental stages. Our results indicate that HDV-like ribozymes are abundant in nature and suggest that self-cleaving RNAs may play a variety of biological roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3159031/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3159031/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Webb, Chiu-Ho T -- Riccitelli, Nathan J -- Ruminski, Dana J -- Luptak, Andrej -- R01 GM094929/GM/NIGMS NIH HHS/ -- R01 GM094929-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):953. doi: 10.1126/science.1178084.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Biochemistry, University of California, Irvine, CA 92697 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965505" target="_blank"〉PubMed〈/a〉

    Description: X-linked adrenoleukodystrophy (ALD) is a severe brain demyelinating disease in boys that is caused by a deficiency in ALD protein, an adenosine triphosphate-binding cassette transporter encoded by the ABCD1 gene. ALD progression can be halted by allogeneic hematopoietic cell transplantation (HCT). We initiated a gene therapy trial in two ALD patients for whom there were no matched donors. Autologous CD34+ cells were removed from the patients, genetically corrected ex vivo with a lentiviral vector encoding wild-type ABCD1, and then re-infused into the patients after they had received myeloablative treatment. Over a span of 24 to 30 months of follow-up, we detected polyclonal reconstitution, with 9 to 14% of granulocytes, monocytes, and T and B lymphocytes expressing the ALD protein. These results strongly suggest that hematopoietic stem cells were transduced in the patients. Beginning 14 to 16 months after infusion of the genetically corrected cells, progressive cerebral demyelination in the two patients stopped, a clinical outcome comparable to that achieved by allogeneic HCT. Thus, lentiviral-mediated gene therapy of hematopoietic stem cells can provide clinical benefits in ALD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cartier, Nathalie -- Hacein-Bey-Abina, Salima -- Bartholomae, Cynthia C -- Veres, Gabor -- Schmidt, Manfred -- Kutschera, Ina -- Vidaud, Michel -- Abel, Ulrich -- Dal-Cortivo, Liliane -- Caccavelli, Laure -- Mahlaoui, Nizar -- Kiermer, Veronique -- Mittelstaedt, Denice -- Bellesme, Celine -- Lahlou, Najiba -- Lefrere, Francois -- Blanche, Stephane -- Audit, Muriel -- Payen, Emmanuel -- Leboulch, Philippe -- l'Homme, Bruno -- Bougneres, Pierre -- Von Kalle, Christof -- Fischer, Alain -- Cavazzana-Calvo, Marina -- Aubourg, Patrick -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):818-23. doi: 10.1126/science.1171242.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM UMR745, University Paris-Descartes, 75279 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892975" target="_blank"〉PubMed〈/a〉

    Description: Placebo analgesia is a prime example of the impact that psychological factors have on pain perception. We used functional magnetic resonance imaging of the human spinal cord to test the hypothesis that placebo analgesia results in a reduction of nociceptive processing in the spinal cord. In line with behavioral data that show decreased pain responses under placebo, pain-related activity in the spinal cord is strongly reduced under placebo. These results provide direct evidence for spinal inhibition as one mechanism of placebo analgesia and highlight that psychological factors can act on the earliest stages of pain processing in the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eippert, Falk -- Finsterbusch, Jurgen -- Bingel, Ulrike -- Buchel, Christian -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):404. doi: 10.1126/science.1180142.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Neuroscience, University Medical Center Hamburg-Eppendorf, 20246 Hamburg, Germany. f.eippert@uke.uni-hamburg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833962" target="_blank"〉PubMed〈/a〉

    Description: Despite tremendous progress in understanding the nature of the immune system, the full diversity of an organism's antibody repertoire is unknown. We used high-throughput sequencing of the variable domain of the antibody heavy chain from 14 zebrafish to analyze VDJ usage and antibody sequence. Zebrafish were found to use between 50 and 86% of all possible VDJ combinations and shared a similar frequency distribution, with some correlation of VDJ patterns between individuals. Zebrafish antibodies retained a few thousand unique heavy chains that also exhibited a shared frequency distribution. We found evidence of convergence, in which different individuals made the same antibody. This approach provides insight into the breadth of the expressed antibody repertoire and immunological diversity at the level of an individual organism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086368/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086368/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, Joshua A -- Jiang, Ning -- White, Richard A 3rd -- Fisher, Daniel S -- Quake, Stephen R -- DP1 OD000251/OD/NIH HHS/ -- DP1 OD000251-04/OD/NIH HHS/ -- DP1 OD000251-05/OD/NIH HHS/ -- DP1 OD000251-06/OD/NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):807-10. doi: 10.1126/science.1170020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics Program, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423829" target="_blank"〉PubMed〈/a〉

    Description: Compared with more explicit racial slurs and statements, biased facial expressions and body language may resist conscious identification and thus produce a hidden social influence. In four studies, we show that race biases can be subtly transmitted via televised nonverbal behavior. Characters on 11 popular television shows exhibited more negative nonverbal behavior toward black than toward status-matched white characters. Critically, exposure to prowhite (versus problack) nonverbal bias increased viewers' bias even though patterns of nonverbal behavior could not be consciously reported. These findings suggest that hidden patterns of televised nonverbal behavior influence bias among viewers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764987/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764987/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weisbuch, Max -- Pauker, Kristin -- Ambady, Nalini -- F32 MH078350/MH/NIMH NIH HHS/ -- F32MH078350/MH/NIMH NIH HHS/ -- R01 MH070833/MH/NIMH NIH HHS/ -- R01 MH070833-02/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1711-4. doi: 10.1126/science.1178358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Tufts University, 490 Boston Avenue, Medford, MA 02155, USA. max.weisbuch@tufts.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019288" target="_blank"〉PubMed〈/a〉

    Description: Pleuropulmonary blastoma (PPB) is a rare pediatric lung tumor that is often part of an inherited cancer syndrome. PPBs consist of mesenchymal cells that are susceptible to malignant transformation and cysts lined by epithelial cells. In a subset of patients, overgrowth of the cysts by mesenchymal cells leads to sarcoma formation. Here, we show that 11 multiplex PPB families harbor heterozygous germline mutations in DICER1, a gene encoding an endoribonuclease critical to the generation of small noncoding regulatory RNAs. Expression of DICER1 protein was undetectable in the epithelial component of PPB tumors but was retained in the malignant mesenchyme (sarcoma). We hypothesize that loss of DICER1 in the epithelium of the developing lung alters the regulation of diffusible factors that promote mesenchymal proliferation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3098036/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3098036/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hill, D Ashley -- Ivanovich, Jennifer -- Priest, John R -- Gurnett, Christina A -- Dehner, Louis P -- Desruisseau, David -- Jarzembowski, Jason A -- Wikenheiser-Brokamp, Kathryn A -- Suarez, Brian K -- Whelan, Alison J -- Williams, Gretchen -- Bracamontes, Dawn -- Messinger, Yoav -- Goodfellow, Paul J -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA091842-07/CA/NCI NIH HHS/ -- P30 CA091842-08/CA/NCI NIH HHS/ -- R01 CA143167/CA/NCI NIH HHS/ -- R01 HL109265/HL/NHLBI NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):965. doi: 10.1126/science.1174334.

    Description: Existing research reports inconsistent findings with regard to the effect of color on cognitive task performances. Some research suggests that blue or green leads to better performances than red; other studies record the opposite. Current work reconciles this discrepancy. We demonstrate that red (versus blue) color induces primarily an avoidance (versus approach) motivation (study 1, n = 69) and that red enhances performance on a detail-oriented task, whereas blue enhances performance on a creative task (studies 2 and 3, n = 208 and 118). Further, we replicate these results in the domains of product design (study 4, n = 42) and persuasive message evaluation (study 5, n = 161) and show that these effects occur outside of individuals' consciousness (study 6, n = 68). We also provide process evidence suggesting that the activation of alternative motivations mediates the effect of color on cognitive task performances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehta, Ravi -- Zhu, Rui Juliet -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1226-9. doi: 10.1126/science.1169144.

    Description: Sexual conflict occurs when males and females act against each others' interest, typically resulting in selection favoring harmful males. We performed laboratory experiments on sexual conflict that both confined individuals in isolated groups, which prevents selection acting counter to this conflict, and provided more naturalistic multigroup population structures. We show that in water striders, aggressive male mating behavior was strongly favored within groups but not favored in a multigroup population when individuals can freely disperse among groups. These observations explain the persistence of less-aggressive males within natural populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eldakar, Omar Tonsi -- Dlugos, Michael J -- Pepper, John W -- Wilson, David Sloan -- 5 K12 GM000708/GM/NIGMS NIH HHS/ -- K12 GM000708/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):816. doi: 10.1126/science.1180183.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Insect Science, University of Arizona, Tucson, AZ 85721, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892974" target="_blank"〉PubMed〈/a〉

    Description: The familiar buzz of flying mosquitoes is an important mating signal, with the fundamental frequency of the female's flight tone signaling her presence. In the yellow fever and dengue vector Aedes aegypti, both sexes interact acoustically by shifting their flight tones to match, resulting in a courtship duet. Matching is made not at the fundamental frequency of 400 hertz (female) or 600 hertz (male) but at a shared harmonic of 1200 hertz, which exceeds the previously known upper limit of hearing in mosquitoes. Physiological recordings from Johnston's organ (the mosquito's "ear") reveal sensitivity up to 2000 hertz, consistent with our observed courtship behavior. These findings revise widely accepted limits of acoustic behavior in mosquitoes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cator, Lauren J -- Arthur, Ben J -- Harrington, Laura C -- Hoy, Ronald R -- R01 DC000103/DC/NIDCD NIH HHS/ -- R01 DC000103-34/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 20;323(5917):1077-9. doi: 10.1126/science.1166541.

    Description: Primordial organisms of the putative RNA world would have required polymerase ribozymes able to replicate RNA. Known ribozymes with polymerase activity best approximating that needed for RNA replication contain at their catalytic core the class I RNA ligase, an artificial ribozyme with a catalytic rate among the fastest of known ribozymes. Here we present the 3.0 angstrom crystal structure of this ligase. The architecture resembles a tripod, its three legs converging near the ligation junction. Interacting with this tripod scaffold through a series of 10 minor-groove interactions (including two A-minor triads) is the unpaired segment that contributes to and organizes the active site. A cytosine nucleobase and two backbone phosphates abut the ligation junction; their location suggests a model for catalysis resembling that of proteinaceous polymerases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3978776/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3978776/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shechner, David M -- Grant, Robert A -- Bagby, Sarah C -- Koldobskaya, Yelena -- Piccirilli, Joseph A -- Bartel, David P -- GM61835/GM/NIGMS NIH HHS/ -- R01 GM061835/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1271-5. doi: 10.1126/science.1174676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research and Howard Hughes Medical Institute, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965478" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenia is a devastating, highly heritable brain disorder of unknown etiology. Recently, the first common genetic variant associated on a genome-wide level with schizophrenia and possibly bipolar disorder was discovered in ZNF804A (rs1344706). We show, by using an imaging genetics approach, that healthy carriers of rs1344706 risk genotypes exhibit no changes in regional activity but pronounced gene dosage-dependent alterations in functional coupling (correlated activity) of dorsolateral prefrontal cortex (DLPFC) across hemispheres and with hippocampus, mirroring findings in patients, and abnormal coupling of amygdala. Our findings establish disturbed connectivity as a neurogenetic risk mechanism for psychosis supported by genome-wide association, show that rs1344706 or variation in linkage disequilibrium is functional in human brain, and validate the intermediate phenotype strategy in psychiatry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Esslinger, Christine -- Walter, Henrik -- Kirsch, Peter -- Erk, Susanne -- Schnell, Knut -- Arnold, Claudia -- Haddad, Leila -- Mier, Daniela -- Opitz von Boberfeld, Carola -- Raab, Kyeon -- Witt, Stephanie H -- Rietschel, Marcella -- Cichon, Sven -- Meyer-Lindenberg, Andreas -- New York, N.Y. -- Science. 2009 May 1;324(5927):605. doi: 10.1126/science.1167768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Psychotherapy, Central Institute of Mental Health, University of Heidelberg, J5, 68159 Mannheim, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19407193" target="_blank"〉PubMed〈/a〉

    Description: Hybrid sterility of the heterogametic sex is one of the first postzygotic reproductive barriers to evolve during speciation, yet the molecular basis of hybrid sterility is poorly understood. We show that the hybrid male sterility gene Odysseus-site homeobox (OdsH) encodes a protein that localizes to evolutionarily dynamic loci within heterochromatin and leads to their decondensation. In Drosophila mauritiana x Drosophila simulans male hybrids, OdsH from D. mauritiana (OdsHmau) acts as a sterilizing factor by associating with the heterochromatic Y chromosome of D. simulans, whereas D. simulans OdsH (OdsHsim) does not. Characterization of sterile hybrid testes revealed that OdsH abundance and localization in the premeiotic phases of spermatogenesis differ between species. These results reveal that rapid heterochromatin evolution affects the onset of hybrid sterility.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987944/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bayes, Joshua J -- Malik, Harmit S -- R01 GM074108/GM/NIGMS NIH HHS/ -- R01 GM074108-05/GM/NIGMS NIH HHS/ -- R01-GM74108/GM/NIGMS NIH HHS/ -- T32 GM07270/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1538-41. doi: 10.1126/science.1181756.

    Description: Mitochondria continuously undergo two opposing processes, fission and fusion. The disruption of this dynamic equilibrium may herald cell injury or death and may contribute to developmental and neurodegenerative disorders. Nitric oxide functions as a signaling molecule, but in excess it mediates neuronal injury, in part via mitochondrial fission or fragmentation. However, the underlying mechanism for nitric oxide-induced pathological fission remains unclear. We found that nitric oxide produced in response to beta-amyloid protein, thought to be a key mediator of Alzheimer's disease, triggered mitochondrial fission, synaptic loss, and neuronal damage, in part via S-nitrosylation of dynamin-related protein 1 (forming SNO-Drp1). Preventing nitrosylation of Drp1 by cysteine mutation abrogated these neurotoxic events. SNO-Drp1 is increased in brains of human Alzheimer's disease patients and may thus contribute to the pathogenesis of neurodegeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823371/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho, Dong-Hyung -- Nakamura, Tomohiro -- Fang, Jianguo -- Cieplak, Piotr -- Godzik, Adam -- Gu, Zezong -- Lipton, Stuart A -- P01 ES016738/ES/NIEHS NIH HHS/ -- P01 ES016738-01/ES/NIEHS NIH HHS/ -- P01 ES016738-010003/ES/NIEHS NIH HHS/ -- P01 ES016738-02/ES/NIEHS NIH HHS/ -- P01 ES016738-020003/ES/NIEHS NIH HHS/ -- P01 HD029587/HD/NICHD NIH HHS/ -- P01 HD029587-16/HD/NICHD NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- P30 NS057096-04/NS/NINDS NIH HHS/ -- R01 EY005477/EY/NEI NIH HHS/ -- R01 EY005477-25/EY/NEI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):102-5. doi: 10.1126/science.1171091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, Aging, and Stem Cell Research, Burnham Institute for Medical Research, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342591" target="_blank"〉PubMed〈/a〉

    Description: Amyotrophic lateral sclerosis (ALS) is a fatal degenerative motor neuron disorder. Ten percent of cases are inherited; most involve unidentified genes. We report here 13 mutations in the fused in sarcoma/translated in liposarcoma (FUS/TLS) gene on chromosome 16 that were specific for familial ALS. The FUS/TLS protein binds to RNA, functions in diverse processes, and is normally located predominantly in the nucleus. In contrast, the mutant forms of FUS/TLS accumulated in the cytoplasm of neurons, a pathology that is similar to that of the gene TAR DNA-binding protein 43 (TDP43), whose mutations also cause ALS. Neuronal cytoplasmic protein aggregation and defective RNA metabolism thus appear to be common pathogenic mechanisms involved in ALS and possibly in other neurodegenerative disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwiatkowski, T J Jr -- Bosco, D A -- Leclerc, A L -- Tamrazian, E -- Vanderburg, C R -- Russ, C -- Davis, A -- Gilchrist, J -- Kasarskis, E J -- Munsat, T -- Valdmanis, P -- Rouleau, G A -- Hosler, B A -- Cortelli, P -- de Jong, P J -- Yoshinaga, Y -- Haines, J L -- Pericak-Vance, M A -- Yan, J -- Ticozzi, N -- Siddique, T -- McKenna-Yasek, D -- Sapp, P C -- Horvitz, H R -- Landers, J E -- Brown, R H Jr -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1205-8. doi: 10.1126/science.1166066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Massachusetts General Hospital, 114 16th Street, Charlestown, MA 02129, USA. tkwiatkowski@partners.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251627" target="_blank"〉PubMed〈/a〉

    Description: Although the nematode Caenorhabditis elegans produces self-fertile hermaphrodites, it descended from a male/female species, so hermaphroditism provides a model for the origin of novel traits. In the related species C. remanei, which has only male and female sexes, lowering the activity of tra-2 by RNA interference created XX animals that made spermatids as well as oocytes, but their spermatids could not activate without the addition of male seminal fluid. However, by lowering the expression of both tra-2 and swm-1, a gene that regulates sperm activation in C. elegans, we produced XX animals with active sperm that were self-fertile. Thus, the evolution of hermaphroditism in Caenorhabditis probably required two steps: a mutation in the sex-determination pathway that caused XX spermatogenesis and a mutation that allowed these spermatids to self-activate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldi, Chris -- Cho, Soochin -- Ellis, Ronald E -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1002-5. doi: 10.1126/science.1176013.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biomedical Sciences, University of Medicine and Dentistry of New Jersey, Stratford, NJ 08084, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965511" target="_blank"〉PubMed〈/a〉

    Description: Polyphosphate (polyP) occurs ubiquitously in cells, but its functions are poorly understood and its synthesis has only been characterized in bacteria. Using x-ray crystallography, we identified a eukaryotic polyphosphate polymerase within the membrane-integral vacuolar transporter chaperone (VTC) complex. A 2.6 angstrom crystal structure of the catalytic domain grown in the presence of adenosine triphosphate (ATP) reveals polyP winding through a tunnel-shaped pocket. Nucleotide- and phosphate-bound structures suggest that the enzyme functions by metal-assisted cleavage of the ATP gamma-phosphate, which is then in-line transferred to an acceptor phosphate to form polyP chains. Mutational analysis of the transmembrane domain indicates that VTC may integrate cytoplasmic polymer synthesis with polyP membrane translocation. Identification of the polyP-synthesizing enzyme opens the way to determine the functions of polyP in lower eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hothorn, Michael -- Neumann, Heinz -- Lenherr, Esther D -- Wehner, Mark -- Rybin, Vladimir -- Hassa, Paul O -- Uttenweiler, Andreas -- Reinhardt, Monique -- Schmidt, Andrea -- Seiler, Jeanette -- Ladurner, Andreas G -- Herrmann, Christian -- Scheffzek, Klaus -- Mayer, Andreas -- G0500367/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):513-6. doi: 10.1126/science.1168120.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Molecular Biology Laboratory, Structural and Computational Biology Unit, Meyerhofstrasse 1, 69117 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390046" target="_blank"〉PubMed〈/a〉

    Description: Elongation factor G (EF-G) is a guanosine triphosphatase (GTPase) that plays a crucial role in the translocation of transfer RNAs (tRNAs) and messenger RNA (mRNA) during translation by the ribosome. We report a crystal structure refined to 3.6 angstrom resolution of the ribosome trapped with EF-G in the posttranslocational state using the antibiotic fusidic acid. Fusidic acid traps EF-G in a conformation intermediate between the guanosine triphosphate and guanosine diphosphate forms. The interaction of EF-G with ribosomal elements implicated in stimulating catalysis, such as the L10-L12 stalk and the L11 region, and of domain IV of EF-G with the tRNA at the peptidyl-tRNA binding site (P site) and with mRNA shed light on the role of these elements in EF-G function. The stabilization of the mobile stalks of the ribosome also results in a more complete description of its structure.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3763468/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3763468/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, Yong-Gui -- Selmer, Maria -- Dunham, Christine M -- Weixlbaumer, Albert -- Kelley, Ann C -- Ramakrishnan, V -- 082086/Wellcome Trust/United Kingdom -- MC_U105184332/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Oct 30;326(5953):694-9. doi: 10.1126/science.1179709.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MRC Laboratory of Molecular Biology, Hills Road, Cambridge, CB2 0QH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833919" target="_blank"〉PubMed〈/a〉

    Description: The brain's sensitivity to unexpected outcomes plays a fundamental role in an organism's ability to adapt and learn new behaviors. Emerging research suggests that midbrain dopaminergic neurons encode these unexpected outcomes. We used microelectrode recordings during deep brain stimulation surgery to study neuronal activity in the human substantia nigra (SN) while patients with Parkinson's disease engaged in a probabilistic learning task motivated by virtual financial rewards. Based on a model of the participants' expected reward, we divided trial outcomes into expected and unexpected gains and losses. SN neurons exhibited significantly higher firing rates after unexpected gains than unexpected losses. No such differences were observed after expected gains and losses. This result provides critical support for the hypothesized role of the SN in human reinforcement learning.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2839450/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2839450/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaghloul, Kareem A -- Blanco, Justin A -- Weidemann, Christoph T -- McGill, Kathryn -- Jaggi, Jurg L -- Baltuch, Gordon H -- Kahana, Michael J -- MH062196/MH/NIMH NIH HHS/ -- MH61975/MH/NIMH NIH HHS/ -- P50 MH062196/MH/NIMH NIH HHS/ -- P50 MH062196-090008/MH/NIMH NIH HHS/ -- R01 MH061975/MH/NIMH NIH HHS/ -- R01 MH061975-08/MH/NIMH NIH HHS/ -- R01 NS048598/NS/NINDS NIH HHS/ -- R01 NS048598-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1496-9. doi: 10.1126/science.1167342.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosurgery, University of Pennsylvania, Philadelphia, PA 19104, USA. zaghlouk@uphs.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286561" target="_blank"〉PubMed〈/a〉

    Description: We tested whether classroom activities that encourage students to connect course materials to their lives will increase student motivation and learning. We hypothesized that this effect will be stronger for students who have low expectations of success. In a randomized field experiment with high school students, we found that a relevance intervention, which encouraged students to make connections between their lives and what they were learning in their science courses, increased interest in science and course grades for students with low success expectations. The results have implications for the development of science curricula and theories of motivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hulleman, Chris S -- Harackiewicz, Judith M -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1410-2. doi: 10.1126/science.1177067.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Graduate Psychology, James Madison University, Harrisonburg, VA 22807, USA. hullemcs@jmu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965759" target="_blank"〉PubMed〈/a〉

    Description: A major cause for biodiversity may be biodiversity itself. As new species form, they may create new niches for others to exploit, potentially catalyzing a chain reaction of speciation events across trophic levels. We tested for such sequential radiation in the Rhagoletis pomonella (Diptera: Tephritidae) complex, a model for sympatric speciation via host plant shifting. We report that the parasitic wasp Diachasma alloeum (Hymenoptera: Braconidae) has formed new incipient species as a result of specializing on diversifying fly hosts, including the recently derived apple-infesting race of R. pomonella. Furthermore, we show that traits that differentially adapt R. pomonella flies to their host plants have also quickly evolved and serve as ecological barriers to reproduction, isolating the wasps. Speciation therefore cascades as the effects of new niche construction move across trophic levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Forbes, Andrew A -- Powell, Thomas H Q -- Stelinski, Lukasz L -- Smith, James J -- Feder, Jeffrey L -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):776-9. doi: 10.1126/science.1166981.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Notre Dame, Galvin Life Sciences Building, Notre Dame, IN 46556, USA. aaforbes@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197063" target="_blank"〉PubMed〈/a〉

    Description: Compared with the enormous arsenal of catalysts used to produce organic compounds, complementary species that are able to mediate sophisticated organometallic transformations are virtually nonexistent. We found that stable N-heterocyclic carbenes (NHCs) can mediate unusual organometallic transformations in solution at room temperature. Depending on the choice of NHC initiator, stoichiometric or catalytic reactions of bis(cyclooctatetraene)iron [Fe(COT)2] ensue. The stoichiometric reaction leads to the isolation of a previously unknown mixed-valent species, featuring distinct and directly bonded Fe(0) and Fe(I) centers. In the catalytic process, three iron atoms are fused to afford the tri-iron cluster Fe3(COT)3, which is a hydrocarbon analog of Dewar's classic Fe3(CO)12 complex. The key step in both of these processes is proposed to involve the NHC's ability to induce metal-metal bond formation. These NHC-mediated reactions provide a foundation on which to develop future organometallic transformations that are catalyzed by organic species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2841742/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2841742/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lavallo, Vincent -- Grubbs, Robert H -- 5R01 GM31332/GM/NIGMS NIH HHS/ -- F32 GM085916/GM/NIGMS NIH HHS/ -- F32 GM085916-01/GM/NIGMS NIH HHS/ -- F32 GM085916-02/GM/NIGMS NIH HHS/ -- R01 GM031332/GM/NIGMS NIH HHS/ -- R01 GM031332-25/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):559-62. doi: 10.1126/science.1178919.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Arnold and Mabel Beckman Laboratory of Chemical Synthesis, Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19900894" target="_blank"〉PubMed〈/a〉

    Description: Dysregulation of the fear system is at the core of many psychiatric disorders. Much progress has been made in uncovering the neural basis of fear learning through studies in which associative emotional memories are formed by pairing an initially neutral stimulus (conditioned stimulus, CS; e.g., a tone) to an unconditioned stimulus (US; e.g., a shock). Despite recent advances, the question of how to persistently weaken aversive CS-US associations, or dampen traumatic memories in pathological cases, remains a major dilemma. Two paradigms (blockade of reconsolidation and extinction) have been used in the laboratory to reduce acquired fear. Unfortunately, their clinical efficacy is limited: Reconsolidation blockade typically requires potentially toxic drugs, and extinction is not permanent. Here, we describe a behavioral design in which a fear memory in rats is destabilized and reinterpreted as safe by presenting an isolated retrieval trial before an extinction session. This procedure permanently attenuates the fear memory without the use of drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3625935/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3625935/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Monfils, Marie-H -- Cowansage, Kiriana K -- Klann, Eric -- LeDoux, Joseph E -- F31 MH083472/MH/NIMH NIH HHS/ -- F31 MH083472-01A1/MH/NIMH NIH HHS/ -- F31MH083472/MH/NIMH NIH HHS/ -- K05 MH067048/MH/NIMH NIH HHS/ -- NS034007/NS/NINDS NIH HHS/ -- NS047384/NS/NINDS NIH HHS/ -- P50 MH058911/MH/NIMH NIH HHS/ -- R01 MH046516/MH/NIMH NIH HHS/ -- R37 MH038774/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 May 15;324(5929):951-5. doi: 10.1126/science.1167975.

    Description: A single-base pair resolution silkworm genetic variation map was constructed from 40 domesticated and wild silkworms, each sequenced to approximately threefold coverage, representing 99.88% of the genome. We identified ~16 million single-nucleotide polymorphisms, many indels, and structural variations. We find that the domesticated silkworms are clearly genetically differentiated from the wild ones, but they have maintained large levels of genetic variability, suggesting a short domestication event involving a large number of individuals. We also identified signals of selection at 354 candidate genes that may have been important during domestication, some of which have enriched expression in the silk gland, midgut, and testis. These data add to our understanding of the domestication processes and may have applications in devising pest control strategies and advancing the use of silkworms as efficient bioreactors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951477/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951477/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xia, Qingyou -- Guo, Yiran -- Zhang, Ze -- Li, Dong -- Xuan, Zhaoling -- Li, Zhuo -- Dai, Fangyin -- Li, Yingrui -- Cheng, Daojun -- Li, Ruiqiang -- Cheng, Tingcai -- Jiang, Tao -- Becquet, Celine -- Xu, Xun -- Liu, Chun -- Zha, Xingfu -- Fan, Wei -- Lin, Ying -- Shen, Yihong -- Jiang, Lan -- Jensen, Jeffrey -- Hellmann, Ines -- Tang, Si -- Zhao, Ping -- Xu, Hanfu -- Yu, Chang -- Zhang, Guojie -- Li, Jun -- Cao, Jianjun -- Liu, Shiping -- He, Ningjia -- Zhou, Yan -- Liu, Hui -- Zhao, Jing -- Ye, Chen -- Du, Zhouhe -- Pan, Guoqing -- Zhao, Aichun -- Shao, Haojing -- Zeng, Wei -- Wu, Ping -- Li, Chunfeng -- Pan, Minhui -- Li, Jingjing -- Yin, Xuyang -- Li, Dawei -- Wang, Juan -- Zheng, Huisong -- Wang, Wen -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Lu, Cheng -- Nielsen, Rasmus -- Zhou, Zeyang -- Wang, Jian -- Xiang, Zhonghuai -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):433-6. doi: 10.1126/science.1176620.

    Description: Adult stem cells often reside in local microenvironments, or niches. Although niches can contain multiple types of stem cells, the coordinate regulation of stem cell behavior is poorly understood. In the Drosophila testis, Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling is directly required for maintenance of the resident germline and somatic stem cells. We found that the JAK-STAT signaling target and inhibitor Suppressor of cytokine signaling 36E (SOCS36E) is required for germline stem cell maintenance. SOCS36E suppresses JAK-STAT signaling specifically in the somatic stem cells, preventing them from displacing neighboring germline stem cells in a manner that depends on the adhesion protein integrin. Thus, in niches housing multiple stem cell types, negative feedback loops can modulate signaling, preventing one stem cell population from outcompeting the other.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3073347/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3073347/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Issigonis, Melanie -- Tulina, Natalia -- de Cuevas, Margaret -- Brawley, Crista -- Sandler, Laurel -- Matunis, Erika -- R01 HD040307/HD/NICHD NIH HHS/ -- R01 HD040307-05A1/HD/NICHD NIH HHS/ -- R01 HD052937/HD/NICHD NIH HHS/ -- R01 HD052937-01A1/HD/NICHD NIH HHS/ -- R01HD40307/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):153-6. doi: 10.1126/science.1176817.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Johns Hopkins University School of Medicine, 725 North Wolfe Street, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19797664" target="_blank"〉PubMed〈/a〉

    Description: Itch and pain are two distinct sensations. Although our previous study suggested that gastrin-releasing peptide receptor (GRPR) is an itch-specific gene in the spinal cord, a long-standing question of whether there are separate neuronal pathways for itch and pain remains unsettled. We selectively ablated lamina I neurons expressing GRPR in the spinal cord of mice. These mice showed profound scratching deficits in response to all of the itching (pruritogenic) stimuli tested, irrespective of their histamine dependence. In contrast, pain behaviors were unaffected. Our data also suggest that GRPR+ neurons are different from the spinothalamic tract neurons that have been the focus of the debate. Together, the present study suggests that GRPR+ neurons constitute a long-sought labeled line for itch sensation in the spinal cord.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2786498/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2786498/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, Yan-Gang -- Zhao, Zhong-Qiu -- Meng, Xiu-Li -- Yin, Jun -- Liu, Xian-Yu -- Chen, Zhou-Feng -- P01 NS049048-23/NS/NINDS NIH HHS/ -- P30 NS057105/NS/NINDS NIH HHS/ -- P30 NS057105-04/NS/NINDS NIH HHS/ -- R01 AR056318/AR/NIAMS NIH HHS/ -- R01 AR056318-01A1/AR/NIAMS NIH HHS/ -- R01 NS046036/NS/NINDS NIH HHS/ -- R01 NS046036-05/NS/NINDS NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 18;325(5947):1531-4. doi: 10.1126/science.1174868.

    Description: Heterozygous mutations in the gene encoding isocitrate dehydrogenase-1 (IDH1) occur in certain human brain tumors, but their mechanistic role in tumor development is unknown. We have shown that tumor-derived IDH1 mutations impair the enzyme's affinity for its substrate and dominantly inhibit wild-type IDH1 activity through the formation of catalytically inactive heterodimers. Forced expression of mutant IDH1 in cultured cells reduces formation of the enzyme product, alpha-ketoglutarate (alpha-KG), and increases the levels of hypoxia-inducible factor subunit HIF-1alpha, a transcription factor that facilitates tumor growth when oxygen is low and whose stability is regulated by alpha-KG. The rise in HIF-1alpha levels was reversible by an alpha-KG derivative. HIF-1alpha levels were higher in human gliomas harboring an IDH1 mutation than in tumors without a mutation. Thus, IDH1 appears to function as a tumor suppressor that, when mutationally inactivated, contributes to tumorigenesis in part through induction of the HIF-1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251015/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251015/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Shimin -- Lin, Yan -- Xu, Wei -- Jiang, Wenqing -- Zha, Zhengyu -- Wang, Pu -- Yu, Wei -- Li, Zhiqiang -- Gong, Lingling -- Peng, Yingjie -- Ding, Jianping -- Lei, Qunying -- Guan, Kun-Liang -- Xiong, Yue -- R01 CA068377/CA/NCI NIH HHS/ -- R01 CA068377-14/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):261-5. doi: 10.1126/science.1170944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biology Laboratory, Institute of Biomedical Sciences, Fudan University, 130 Dong-An Road, Shanghai 200032, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359588" target="_blank"〉PubMed〈/a〉

    Description: The toolbox of rat genetics currently lacks the ability to introduce site-directed, heritable mutations into the genome to create knockout animals. By using engineered zinc-finger nucleases (ZFNs) designed to target an integrated reporter and two endogenous rat genes, Immunoglobulin M (IgM) and Rab38, we demonstrate that a single injection of DNA or messenger RNA encoding ZFNs into the one-cell rat embryo leads to a high frequency of animals carrying 25 to 100% disruption at the target locus. These mutations are faithfully and efficiently transmitted through the germline. Our data demonstrate the feasibility of targeted gene disruption in multiple rat strains within 4 months time, paving the way to a humanized monoclonal antibody platform and additional human disease models.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2831805/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2831805/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geurts, Aron M -- Cost, Gregory J -- Freyvert, Yevgeniy -- Zeitler, Bryan -- Miller, Jeffrey C -- Choi, Vivian M -- Jenkins, Shirin S -- Wood, Adam -- Cui, Xiaoxia -- Meng, Xiangdong -- Vincent, Anna -- Lam, Stephen -- Michalkiewicz, Mieczyslaw -- Schilling, Rebecca -- Foeckler, Jamie -- Kalloway, Shawn -- Weiler, Hartmut -- Menoret, Severine -- Anegon, Ignacio -- Davis, Gregory D -- Zhang, Lei -- Rebar, Edward J -- Gregory, Philip D -- Urnov, Fyodor D -- Jacob, Howard J -- Buelow, Roland -- 5P01HL082798-03/HL/NHLBI NIH HHS/ -- 5U01HL066579-08/HL/NHLBI NIH HHS/ -- P01 HL082798/HL/NHLBI NIH HHS/ -- P01 HL082798-03/HL/NHLBI NIH HHS/ -- U01 HL066579/HL/NHLBI NIH HHS/ -- U01 HL066579-08/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):433. doi: 10.1126/science.1172447.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human and Molecular Genetics Center, Medical College of Wisconsin, Milwaukee, WI 52336, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19628861" target="_blank"〉PubMed〈/a〉

    Description: Controlling the morphology of Pt nanostructures can provide a great opportunity to improve their catalytic properties and increase their activity on a mass basis. We synthesized Pd-Pt bimetallic nanodendrites consisting of a dense array of Pt branches on a Pd core by reducing K2PtCl4 with L-ascorbic acid in the presence of uniform Pd nanocrystal seeds in an aqueous solution. The Pt branches supported on faceted Pd nanocrystals exhibited relatively large surface areas and particularly active facets toward the oxygen reduction reaction (ORR), the rate-determining step in a proton-exchange membrane fuel cell. The Pd-Pt nanodendrites were two and a half times more active on the basis of equivalent Pt mass for the ORR than the state-of-the-art Pt/C catalyst and five times more active than the first-generation supportless Pt-black catalyst.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lim, Byungkwon -- Jiang, Majiong -- Camargo, Pedro H C -- Cho, Eun Chul -- Tao, Jing -- Lu, Xianmao -- Zhu, Yimei -- Xia, Younan -- New York, N.Y. -- Science. 2009 Jun 5;324(5932):1302-5. doi: 10.1126/science.1170377.

    Description: Sex determination mechanisms differ among animal species, but it is not clear how these differences evolve. New sex determiners may arise in response to sexual conflicts, which occur when traits benefit one sex but hinder the other. We identified the genetic basis for the orange-blotch (OB) color pattern, a trait under sexually antagonistic selection in the cichlid fish of Lake Malawi, East Africa. The OB phenotype is due to a cis-regulatory mutation in the Pax7 gene. OB provides benefits of camouflage to females but disrupts the species-specific male color patterns used for mate recognition. We suggest that the resulting sexual conflict over the OB allele has been resolved by selection for a novel female sex determination locus that has invaded populations with an ancestral male sex determination system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3174268/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3174268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Reade B -- Ser, Jennifer R -- Kocher, Thomas D -- F32HD051383/HD/NICHD NIH HHS/ -- R01 HD058635/HD/NICHD NIH HHS/ -- R01 HD058635-04/HD/NICHD NIH HHS/ -- R01HD058635/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):998-1001. doi: 10.1126/science.1174705.

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: Two experiments revealed that (i) people can more accurately predict their affective reactions to a future event when they know how a neighbor in their social network reacted to the event than when they know about the event itself and (ii) people do not believe this. Undergraduates made more accurate predictions about their affective reactions to a 5-minute speed date (n = 25) and to a peer evaluation (n = 88) when they knew only how another undergraduate had reacted to these events than when they had information about the events themselves. Both participants and independent judges mistakenly believed that predictions based on information about the event would be more accurate than predictions based on information about how another person had reacted to it.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, Daniel T -- Killingsworth, Matthew A -- Eyre, Rebecca N -- Wilson, Timothy D -- New York, N.Y. -- Science. 2009 Mar 20;323(5921):1617-9. doi: 10.1126/science.1166632.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Harvard University, Cambridge, MA 02138, USA. gilbert@wjh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19299622" target="_blank"〉PubMed〈/a〉

    Description: Sleep is universal, strictly regulated, and necessary for cognition. Why this is so remains a mystery, although recent work suggests that sleep, memory, and plasticity are linked. However, little is known about how wakefulness and sleep affect synapses. Using Western blots and confocal microscopy in Drosophila, we found that protein levels of key components of central synapses were high after waking and low after sleep. These changes were related to behavioral state rather than time of day and occurred in all major areas of the Drosophila brain. The decrease of synaptic markers during sleep was progressive, and sleep was necessary for their decline. Thus, sleep may be involved in maintaining synaptic homeostasis altered by waking activities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2715914/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2715914/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilestro, Giorgio F -- Tononi, Giulio -- Cirelli, Chiara -- DP1 OD000579/OD/NIH HHS/ -- DP1 OD000579-01/OD/NIH HHS/ -- DP1 OD000579-02/OD/NIH HHS/ -- DP1 OD000579-03/OD/NIH HHS/ -- DP1 OD000579-04/OD/NIH HHS/ -- R01 GM075315/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):109-12. doi: 10.1126/science.1166673.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Wisconsin, Madison, WI 53719, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342593" target="_blank"〉PubMed〈/a〉

    Description: The "royal disease," a blood disorder transmitted from Queen Victoria to European royal families, is a striking example of X-linked recessive inheritance. Although the disease is widely recognized to be a form of the blood clotting disorder hemophilia, its molecular basis has never been identified, and the royal disease is now likely extinct. We identified the likely disease-causing mutation by applying genomic methodologies (multiplex target amplification and massively parallel sequencing) to historical specimens from the Romanov branch of the royal family. The mutation occurs in F9, a gene on the X chromosome that encodes blood coagulation factor IX, and is predicted to alter RNA splicing and to lead to production of a truncated form of factor IX. Thus, the royal disease is the severe form of hemophilia, also known as hemophilia B or Christmas disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogaev, Evgeny I -- Grigorenko, Anastasia P -- Faskhutdinova, Gulnaz -- Kittler, Ellen L W -- Moliaka, Yuri K -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):817. doi: 10.1126/science.1180660.

    Description: Amyloid-beta (Abeta) accumulation in the brain extracellular space is a hallmark of Alzheimer's disease. The factors regulating this process are only partly understood. Abeta aggregation is a concentration-dependent process that is likely responsive to changes in brain interstitial fluid (ISF) levels of Abeta. Using in vivo microdialysis in mice, we found that the amount of ISF Abeta correlated with wakefulness. The amount of ISF Abeta also significantly increased during acute sleep deprivation and during orexin infusion, but decreased with infusion of a dual orexin receptor antagonist. Chronic sleep restriction significantly increased, and a dual orexin receptor antagonist decreased, Abeta plaque formation in amyloid precursor protein transgenic mice. Thus, the sleep-wake cycle and orexin may play a role in the pathogenesis of Alzheimer's disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2789838/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2789838/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Jae-Eun -- Lim, Miranda M -- Bateman, Randall J -- Lee, James J -- Smyth, Liam P -- Cirrito, John R -- Fujiki, Nobuhiro -- Nishino, Seiji -- Holtzman, David M -- AG025824/AG/NIA NIH HHS/ -- AG029524/AG/NIA NIH HHS/ -- AG030946/AG/NIA NIH HHS/ -- K01 AG029524/AG/NIA NIH HHS/ -- K01 AG029524-03/AG/NIA NIH HHS/ -- K23 AG030946/AG/NIA NIH HHS/ -- K23 AG030946-03/AG/NIA NIH HHS/ -- MH072525/MH/NIMH NIH HHS/ -- NS065667/NS/NINDS NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-09/DK/NIDDK NIH HHS/ -- P30 NS057105/NS/NINDS NIH HHS/ -- P30 NS057105-04/NS/NINDS NIH HHS/ -- P50 AG005681/AG/NIA NIH HHS/ -- R01 AG025824/AG/NIA NIH HHS/ -- R01 AG025824-03/AG/NIA NIH HHS/ -- R01 MH072525/MH/NIMH NIH HHS/ -- R01 MH072525-04/MH/NIMH NIH HHS/ -- R01 NS065667/NS/NINDS NIH HHS/ -- R01 NS065667-02/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1005-7. doi: 10.1126/science.1180962.

    Description: Speciation often involves the evolution of incompatible gene interactions that cause sterility or lethality in hybrids between populations. These so-called hybrid incompatibilities occur between two or more functionally divergent loci. We show that the nucleoporin 160kDa (Nup160) gene of the fruitfly Drosophila simulans is incompatible with one or more factors on the D. melanogaster X chromosome, causing hybrid lethality. Nup160 encodes a nuclear pore complex protein and shows evidence of adaptive evolution. Furthermore, the protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826207/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826207/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Shanwu -- Presgraves, Daven C -- R01 GM079543/GM/NIGMS NIH HHS/ -- R01 GM079543-01A1/GM/NIGMS NIH HHS/ -- R01-GM079543/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):779-82. doi: 10.1126/science.1169123.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197064" target="_blank"〉PubMed〈/a〉

    Description: Many metabolic and physiological processes display circadian oscillations. We have shown that the core circadian regulator, CLOCK, is a histone acetyltransferase whose activity is counterbalanced by the nicotinamide adenine dinucleotide (NAD+)-dependent histone deacetylase SIRT1. Here we show that intracellular NAD+ levels cycle with a 24-hour rhythm, an oscillation driven by the circadian clock. CLOCK:BMAL1 regulates the circadian expression of NAMPT (nicotinamide phosphoribosyltransferase), an enzyme that provides a rate-limiting step in the NAD+ salvage pathway. SIRT1 is recruited to the Nampt promoter and contributes to the circadian synthesis of its own coenzyme. Using the specific inhibitor FK866, we demonstrated that NAMPT is required to modulate circadian gene expression. Our findings in mouse embryo fibroblasts reveal an interlocked transcriptional-enzymatic feedback loop that governs the molecular interplay between cellular metabolism and circadian rhythms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakahata, Yasukazu -- Sahar, Saurabh -- Astarita, Giuseppe -- Kaluzova, Milota -- Sassone-Corsi, Paolo -- R01-GM081634/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 1;324(5927):654-7. doi: 10.1126/science.1170803.

    Description: The paradigmatic feature of long-term memory (LTM) is its persistence. However, little is known about the mechanisms that make some LTMs last longer than others. In rats, a long-lasting fear LTM vanished rapidly when the D1 dopamine receptor antagonist SCH23390 was injected into the dorsal hippocampus 12 hours, but not immediately or 9 hours, after the fearful experience. Conversely, intrahippocampal application of the D1 agonist SK38393 at the same critical post-training time converted a rapidly decaying fear LTM into a persistent one. This effect was mediated by brain-derived neurotrophic factor and regulated by the ventral tegmental area (VTA). Thus, the persistence of LTM depends on activation of VTA/hippocampus dopaminergic connections and can be specifically modulated by manipulating this system at definite post-learning time points.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rossato, Janine I -- Bevilaqua, Lia R M -- Izquierdo, Ivan -- Medina, Jorge H -- Cammarota, Martin -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):1017-20. doi: 10.1126/science.1172545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro de Memoria, Instituto do Cerebro, Pontificia Universidade Catolica do Rio Grande do Sul, Porto Alegre, Brazil.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19696353" target="_blank"〉PubMed〈/a〉

    Description: Caloric restriction (CR), without malnutrition, delays aging and extends life span in diverse species; however, its effect on resistance to illness and mortality in primates has not been clearly established. We report findings of a 20-year longitudinal adult-onset CR study in rhesus monkeys aimed at filling this critical gap in aging research. In a population of rhesus macaques maintained at the Wisconsin National Primate Research Center, moderate CR lowered the incidence of aging-related deaths. At the time point reported, 50% of control fed animals survived as compared with 80% of the CR animals. Furthermore, CR delayed the onset of age-associated pathologies. Specifically, CR reduced the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy. These data demonstrate that CR slows aging in a primate species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812811/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812811/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colman, Ricki J -- Anderson, Rozalyn M -- Johnson, Sterling C -- Kastman, Erik K -- Kosmatka, Kristopher J -- Beasley, T Mark -- Allison, David B -- Cruzen, Christina -- Simmons, Heather A -- Kemnitz, Joseph W -- Weindruch, Richard -- P01 AG-11915/AG/NIA NIH HHS/ -- P01 AG011915/AG/NIA NIH HHS/ -- P01 AG011915-11A29002/AG/NIA NIH HHS/ -- P51 RR000167/RR/NCRR NIH HHS/ -- RR020141-01/RR/NCRR NIH HHS/ -- RR15459-01/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):201-4. doi: 10.1126/science.1173635.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wisconsin National Primate Research Center, University of Wisconsin, Madison, WI 53715, USA. rcolman@primate.wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590001" target="_blank"〉PubMed〈/a〉

    Description: In adult animals, fear conditioning induces a permanent memory that is resilient to erasure by extinction. In contrast, during early postnatal development, extinction of conditioned fear leads to memory erasure, suggesting that fear memories are actively protected in adults. We show here that this protection is conferred by extracellular matrix chondroitin sulfate proteoglycans (CSPGs) in the amygdala. The organization of CSPGs into perineuronal nets (PNNs) coincided with the developmental switch in fear memory resilience. In adults, degradation of PNNs by chondroitinase ABC specifically rendered subsequently acquired fear memories susceptible to erasure. This result indicates that intact PNNs mediate the formation of erasure-resistant fear memories and identifies a molecular mechanism closing a postnatal critical period during which traumatic memories can be erased by extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gogolla, Nadine -- Caroni, Pico -- Luthi, Andreas -- Herry, Cyril -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1258-61. doi: 10.1126/science.1174146.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Friedrich Miescher Institute for Biomedical Research, Maulbeerstrasse 66, CH-4058 Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729657" target="_blank"〉PubMed〈/a〉

    Description: Despite the costs of mating, females of most taxa mate with multiple males. Polyandrous females are hypothesized to gain genetic benefits for their offspring, but this assumes paternity bias favoring male genotypes that enhance offspring viability. We determined net male genetic effects on female and offspring fitness in a seed beetle and then tested whether fertilization success was biased in favor of high-quality male genotypes in double mating experiments. Contrary to expectations, high-quality male genotypes consistently had a lower postmating fertilization success in two independent assays. Our results imply that sexually antagonistic adaptations have a major and unappreciated influence on male postmating fertilization success. Such genetic variation renders indirect genetic benefits an unlikely driver of the evolution of polyandry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bilde, Trine -- Foged, Anne -- Schilling, Nadia -- Arnqvist, Goran -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1705-6. doi: 10.1126/science.1171675.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, Evolutionary Biology Centre, University of Uppsala, Norbyvagen 18d, SE - 752 36 Uppsala, Sweden. trine.bilde@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556506" target="_blank"〉PubMed〈/a〉

    Description: Male animals of many species deploy conditional reproductive strategies that contain distinct alternative phenotypes. Such facultatively expressed male tactics are assumed to be due to a single developmental threshold mechanism switching between the expression of two alternative phenotypes. However, we discovered a clade of dung beetles that commonly expresses two threshold mechanisms, resulting in three alternative phenotypes (male trimorphism). Once recognized, we found trimorphism in other beetle families that involves different types of male weapons. Evidence that insects assumed to be dimorphic can express three facultative male forms suggests that we need to adjust how we think about animal mating systems and the evolution of conditional strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowland, J Mark -- Emlen, Douglas J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):773-6. doi: 10.1126/science.1167345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA. rowland@unm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197062" target="_blank"〉PubMed〈/a〉

    Description: Gene fusions play a critical role in cancer progression. The mechanisms underlying their genesis and cell type specificity are not well understood. About 50% of human prostate cancers display a gene fusion involving the 5' untranslated region of TMPRSS2, an androgen-regulated gene, and the protein-coding sequences of ERG, which encodes an erythroblast transformation-specific (ETS) transcription factor. By studying human prostate cancer cells with fluorescence in situ hybridization, we show that androgen signaling induces proximity of the TMPRSS2 and ERG genomic loci, both located on chromosome 21q22.2. Subsequent exposure of the cells to gamma irradiation, which causes DNA double-strand breaks, facilitates the formation of the TMPRSS2-ERG gene fusion. These results may help explain why TMPRSS2-ERG fusions are restricted to the prostate, which is dependent on androgen signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2935583/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2935583/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mani, Ram-Shankar -- Tomlins, Scott A -- Callahan, Kaitlin -- Ghosh, Aparna -- Nyati, Mukesh K -- Varambally, Sooryanarayana -- Palanisamy, Nallasivam -- Chinnaiyan, Arul M -- P50 CA069568/CA/NCI NIH HHS/ -- P50 CA069568-11S10020/CA/NCI NIH HHS/ -- P50CA69568/CA/NCI NIH HHS/ -- R01 CA132874/CA/NCI NIH HHS/ -- R01 CA132874-01A1/CA/NCI NIH HHS/ -- R01CA132874/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1230. doi: 10.1126/science.1178124.

    Description: After the domestication of animals and crops in the Near East some 11,000 years ago, farming had reached much of central Europe by 7500 years before the present. The extent to which these early European farmers were immigrants or descendants of resident hunter-gatherers who had adopted farming has been widely debated. We compared new mitochondrial DNA (mtDNA) sequences from late European hunter-gatherer skeletons with those from early farmers and from modern Europeans. We find large genetic differences between all three groups that cannot be explained by population continuity alone. Most (82%) of the ancient hunter-gatherers share mtDNA types that are relatively rare in central Europeans today. Together, these analyses provide persuasive evidence that the first farmers were not the descendants of local hunter-gatherers but immigrated into central Europe at the onset of the Neolithic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bramanti, B -- Thomas, M G -- Haak, W -- Unterlaender, M -- Jores, P -- Tambets, K -- Antanaitis-Jacobs, I -- Haidle, M N -- Jankauskas, R -- Kind, C-J -- Lueth, F -- Terberger, T -- Hiller, J -- Matsumura, S -- Forster, P -- Burger, J -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):137-40. doi: 10.1126/science.1176869.

    Description: Ten-month-old infants persistently search for a hidden object at its initial hiding place even after observing it being hidden at another location. Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. We replicated these results with dogs (Canis familiaris), who also commit more search errors in ostensive-communicative (in 75% of the total trials) than in noncommunicative (39%) or nonsocial (17%) hiding contexts. However, comparative investigations suggest that communicative signals serve different functions for dogs and infants, whereas human-reared wolves (Canis lupus) do not show doglike context-dependent differences of search errors. We propose that shared sensitivity to human communicative signals stems from convergent social evolution of the Homo and the Canis genera.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Topal, Jozsef -- Gergely, Gyorgy -- Erdohegyi, Agnes -- Csibra, Gergely -- Miklosi, Adam -- G9715587/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1269-72. doi: 10.1126/science.1176960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute for Psychology, Hungarian Academy of Sciences, 1132 Budapest, Hungary. topaljozsef@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729660" target="_blank"〉PubMed〈/a〉

    Description: The neural mechanisms underlying the transition from a drug-nondependent to a drug-dependent state remain elusive. Chronic exposure to drugs has been shown to increase brain-derived neurotrophic factor (BDNF) levels in ventral tegmental area (VTA) neurons. BDNF infusions into the VTA potentiate several behavioral effects of drugs, including psychomotor sensitization and cue-induced drug seeking. We found that a single infusion of BDNF into the VTA promotes a shift from a dopamine-independent to a dopamine-dependent opiate reward system, identical to that seen when an opiate-naive rat becomes dependent and withdrawn. This shift involves a switch in the gamma-aminobutyric acid type A (GABAA) receptors of VTA GABAergic neurons, from inhibitory to excitatory signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2913611/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2913611/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vargas-Perez, Hector -- Ting-A Kee, Ryan -- Walton, Christine H -- Hansen, D Micah -- Razavi, Rozita -- Clarke, Laura -- Bufalino, Mary Rose -- Allison, David W -- Steffensen, Scott C -- van der Kooy, Derek -- AA13666/AA/NIAAA NIH HHS/ -- R01 AA013666/AA/NIAAA NIH HHS/ -- R01 AA013666-09/AA/NIAAA NIH HHS/ -- R01 AA020919/AA/NIAAA NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1732-4. doi: 10.1126/science.1168501.

    Description: Caloric restriction (CR) protects against aging and disease, but the mechanisms by which this affects mammalian life span are unclear. We show in mice that deletion of ribosomal S6 protein kinase 1 (S6K1), a component of the nutrient-responsive mTOR (mammalian target of rapamycin) signaling pathway, led to increased life span and resistance to age-related pathologies, such as bone, immune, and motor dysfunction and loss of insulin sensitivity. Deletion of S6K1 induced gene expression patterns similar to those seen in CR or with pharmacological activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK), a conserved regulator of the metabolic response to CR. Our results demonstrate that S6K1 influences healthy mammalian life-span and suggest that therapeutic manipulation of S6K1 and AMPK might mimic CR and could provide broad protection against diseases of aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selman, Colin -- Tullet, Jennifer M A -- Wieser, Daniela -- Irvine, Elaine -- Lingard, Steven J -- Choudhury, Agharul I -- Claret, Marc -- Al-Qassab, Hind -- Carmignac, Danielle -- Ramadani, Faruk -- Woods, Angela -- Robinson, Iain C A -- Schuster, Eugene -- Batterham, Rachel L -- Kozma, Sara C -- Thomas, George -- Carling, David -- Okkenhaug, Klaus -- Thornton, Janet M -- Partridge, Linda -- Gems, David -- Withers, Dominic J -- BBS/E/B/0000C236/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/B/0000M979/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0800339/Medical Research Council/United Kingdom -- G108/551/Medical Research Council/United Kingdom -- MC_U117531708/Medical Research Council/United Kingdom -- MC_U120027537/Medical Research Council/United Kingdom -- MC_U120097114/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):140-4. doi: 10.1126/science.1177221.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Healthy Ageing, Centre for Diabetes and Endocrinology, Department of Medicine, University College London, London WC1E 6JJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19797661" target="_blank"〉PubMed〈/a〉

    Description: Adults with Asperger syndrome can understand mental states such as desires and beliefs (mentalizing) when explicitly prompted to do so, despite having impairments in social communication. We directly tested the hypothesis that such individuals nevertheless fail to mentalize spontaneously. To this end, we used an eye-tracking task that has revealed the spontaneous ability to mentalize in typically developing infants. We showed that, like infants, neurotypical adults' (n = 17 participants) eye movements anticipated an actor's behavior on the basis of her false belief. This was not the case for individuals with Asperger syndrome (n = 19). Thus, these individuals do not attribute mental states spontaneously, but they may be able to do so in explicit tasks through compensatory learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Senju, Atsushi -- Southgate, Victoria -- White, Sarah -- Frith, Uta -- G0701484/Medical Research Council/United Kingdom -- PTA 037-27-0107/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):883-5. doi: 10.1126/science.1176170.

    Description: The evolution and maintenance of sexual reproduction may involve important tradeoffs because asexual reproduction can double an individual's contribution to the gene pool but reduces diversity. Moreover, in social insects the maintenance of genetic diversity among workers may be important for colony growth and survival. We identified a previously unknown termite breeding system in which both parthenogenesis and sexual reproduction are conditionally used. Queens produce their replacements asexually but use normal sexual reproduction to produce other colony members. These findings show how eusociality can lead to extraordinary reproductive systems and provide important insights into the advantages and disadvantages of sex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuura, Kenji -- Vargo, Edward L -- Kawatsu, Kazutaka -- Labadie, Paul E -- Nakano, Hiroko -- Yashiro, Toshihisa -- Tsuji, Kazuki -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1687. doi: 10.1126/science.1169702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Insect Ecology, Graduate School of Environmental Science, Okayama University, Okayama 700-8530, Japan. kenjijpn@cc.okayama-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325106" target="_blank"〉PubMed〈/a〉

    Description: The liver-expressed microRNA-122 (miR-122) is essential for hepatitis C virus (HCV) RNA accumulation in cultured liver cells, but its potential as a target for antiviral intervention has not been assessed. We found that treatment of chronically infected chimpanzees with a locked nucleic acid (LNA)-modified oligonucleotide (SPC3649) complementary to miR-122 leads to long-lasting suppression of HCV viremia, with no evidence of viral resistance or side effects in the treated animals. Furthermore, transcriptome and histological analyses of liver biopsies demonstrated derepression of target mRNAs with miR-122 seed sites, down-regulation of interferon-regulated genes, and improvement of HCV-induced liver pathology. The prolonged virological response to SPC3649 treatment without HCV rebound holds promise of a new antiviral therapy with a high barrier to resistance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3436126/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3436126/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lanford, Robert E -- Hildebrandt-Eriksen, Elisabeth S -- Petri, Andreas -- Persson, Robert -- Lindow, Morten -- Munk, Martin E -- Kauppinen, Sakari -- Orum, Henrik -- C06 RR 12087/RR/NCRR NIH HHS/ -- C06 RR012087/RR/NCRR NIH HHS/ -- C06 RR012087-01/RR/NCRR NIH HHS/ -- P51 RR013986/RR/NCRR NIH HHS/ -- P51 RR13986/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):198-201. doi: 10.1126/science.1178178.

    Description: mu-Opioid receptor (MOR) agonists represent the gold standard for the treatment of severe pain but may paradoxically also enhance pain sensitivity, that is, lead to opioid-induced hyperalgesia (OIH). We show that abrupt withdrawal from MOR agonists induces long-term potentiation (LTP) at the first synapse in pain pathways. Induction of opioid withdrawal LTP requires postsynaptic activation of heterotrimeric guanine nucleotide-binding proteins and N-methyl-d-aspartate receptors and a rise of postsynaptic calcium concentrations. In contrast, the acute depression by opioids is induced presynaptically at these synapses. Withdrawal LTP can be prevented by tapered withdrawal and shares pharmacology and signal transduction pathways with OIH. These findings provide a previously unrecognized target to selectively combat pro-nociceptive effects of opioids without compromising opioid analgesia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drdla, Ruth -- Gassner, Matthias -- Gingl, Ewald -- Sandkuhler, Jurgen -- P 18129/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):207-10. doi: 10.1126/science.1171759.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Center for Brain Research, Medical University of Vienna, Spitalgasse 4, 1090 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590003" target="_blank"〉PubMed〈/a〉

    Description: Actions performed by others may have different relevance for the observer, and thus lead to different behavioral responses, depending on the regions of space in which they are executed. We found that in rhesus monkeys, the premotor cortex neurons activated by both the execution and the observation of motor acts (mirror neurons) are differentially modulated by the location in space of the observed motor acts relative to the monkey, with about half of them preferring either the monkey's peripersonal or extrapersonal space. A portion of these spatially selective mirror neurons encode space according to a metric representation, whereas other neurons encode space in operational terms, changing their properties according to the possibility that the monkey will interact with the object. These results suggest that a set of mirror neurons encodes the observed motor acts not only for action understanding, but also to analyze such acts in terms of features that are relevant to generating appropriate behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caggiano, Vittorio -- Fogassi, Leonardo -- Rizzolatti, Giacomo -- Thier, Peter -- Casile, Antonino -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):403-6. doi: 10.1126/science.1166818.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cognitive Neurology, Hertie Institute for Clinical Brain Research, University of Tubingen, 72076 Tubingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372433" target="_blank"〉PubMed〈/a〉

    Description: The neural mechanisms supporting the ability to recognize and respond to fictive outcomes, outcomes of actions that one has not taken, remain obscure. We hypothesized that neurons in the anterior cingulate cortex (ACC), which monitors the consequences of actions and mediates subsequent changes in behavior, would respond to fictive reward information. We recorded responses of single neurons during performance of a choice task that provided information about the reward values of options that were not chosen. We found that ACC neurons signal fictive reward information and use a coding scheme similar to that used to signal experienced outcomes. Thus, individual ACC neurons process both experienced and fictive rewards.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3096846/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3096846/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hayden, Benjamin Y -- Pearson, John M -- Platt, Michael L -- 013496/PHS HHS/ -- 023338/PHS HHS/ -- F32 DA023338/DA/NIDA NIH HHS/ -- F32 DA023338-01A1/DA/NIDA NIH HHS/ -- F32 DA023338-02/DA/NIDA NIH HHS/ -- K99 DA027718/DA/NIDA NIH HHS/ -- K99 DA027718-01/DA/NIDA NIH HHS/ -- K99 DA027718-02/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2009 May 15;324(5929):948-50. doi: 10.1126/science.1168488.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Duke University School of Medicine, Center for Neuroeconomic Studies, Center for Cognitive Neuroscience, Duke University, Durham, NC 27701, USA. hayden@neuro.duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19443783" target="_blank"〉PubMed〈/a〉

    Description: Sleep is important for memory consolidation and is responsive to waking experience. Clock circuitry is uniquely positioned to coordinate interactions between processes underlying memory and sleep need. Flies increase sleep both after exposure to an enriched social environment and after protocols that induce long-term memory. We found that flies mutant for rutabaga, period, and blistered were deficient for experience-dependent increases in sleep. Rescue of each of these genes within the ventral lateral neurons (LNVs) restores increased sleep after social enrichment. Social experiences that induce increased sleep were associated with an increase in the number of synaptic terminals in the LNV projections into the medulla. The number of synaptic terminals was reduced during sleep and this decline was prevented by sleep deprivation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2850598/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2850598/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Donlea, Jeffrey M -- Ramanan, Narendrakumar -- Shaw, Paul J -- F31 NS063514-01A1/NS/NINDS NIH HHS/ -- R01-NS051305-01A1/NS/NINDS NIH HHS/ -- T32-GM008151/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):105-8. doi: 10.1126/science.1166657.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, Washington University in St. Louis, 660 South Euclid Avenue, St. Louis, Missouri, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342592" target="_blank"〉PubMed〈/a〉

    Description: Most pathogens require a relatively long period of development in their mosquito vector before they can be transmitted to a new human host; hence, only older insects are of epidemiological importance. The successful transfer of a life-shortening strain of the inherited bacterial symbiont, Wolbachia, into the major mosquito vector of dengue, Aedes aegypti, halved adult life span under laboratory conditions. The association is stable, and the Wolbachia strain is maternally inherited at high frequency. It is capable of inducing complete cytoplasmic incompatibility, which should facilitate its invasion into natural field populations and its persistence over time. Our data suggest that targeting mosquito age with inherited Wolbachia infections may be a viable strategy to reduce the transmission of pathogens such as dengue viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMeniman, Conor J -- Lane, Roxanna V -- Cass, Bodil N -- Fong, Amy W C -- Sidhu, Manpreet -- Wang, Yu-Feng -- O'Neill, Scott L -- New York, N.Y. -- Science. 2009 Jan 2;323(5910):141-4. doi: 10.1126/science.1165326.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Integrative Biology, University of Queensland, Brisbane 4072, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19119237" target="_blank"〉PubMed〈/a〉

    Description: Despite increasing pharmaceutical importance, fluorinated aromatic organic molecules remain difficult to synthesize. Present methods require either harsh reaction conditions or highly specialized reagents, making the preparation of complex fluoroarenes challenging. Thus, the development of general methods for their preparation that overcome the limitations of those techniques currently in use is of great interest. We have prepared [LPd(II)Ar(F)] complexes, where L is a biaryl monophosphine ligand and Ar is an aryl group, and identified conditions under which reductive elimination occurs to form an Ar-F bond. On the basis of these results, we have developed a catalytic process that converts aryl bromides and aryl triflates into the corresponding fluorinated arenes by using simple fluoride salts. We expect this method to allow the introduction of fluorine atoms into advanced, highly functionalized intermediates.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3038120/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3038120/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, Donald A -- Su, Mingjuan -- Teverovskiy, Georgiy -- Zhang, Yong -- Garcia-Fortanet, Jorge -- Kinzel, Tom -- Buchwald, Stephen L -- GM46059/GM/NIGMS NIH HHS/ -- R01 GM046059/GM/NIGMS NIH HHS/ -- R37 GM046059/GM/NIGMS NIH HHS/ -- R37 GM046059-18/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1661-4. doi: 10.1126/science.1178239.

    Description: Every social group needs to decide when to provide public goods and how to allocate the costs among its members. Ideally, this decision would maximize the group's net benefits while also ensuring that every individual's benefit is greater than the cost he or she has to pay. Unfortunately, the economic theory of mechanism design has shown that this ideal solution is not feasible when the group leadership does not know the values of the individual group members for the public good. We show that this impossibility result can be overcome in laboratory settings by combining technologies for obtaining neural measures of value (functional magnetic resonance imaging-based pattern classification) with carefully designed institutions that allocate costs based on both reported and neurally measured values.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krajbich, Ian -- Camerer, Colin -- Ledyard, John -- Rangel, Antonio -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):596-9. doi: 10.1126/science.1177302.

    Description: During social interactions, humans often unconsciously and unintentionally imitate the behaviors of others, which increases rapport, liking, and empathy between interaction partners. This effect is thought to be an evolutionary adaptation that facilitates group living and may be shared with other primate species. Here, we show that capuchin monkeys, a highly social primate species, prefer human imitators over non-imitators in a variety of ways: The monkeys look longer at imitators, spend more time in proximity to imitators, and choose to interact more frequently with imitators in a token exchange task. These results demonstrate that imitation can promote affiliation in nonhuman primates. Behavior matching that leads to prosocial behaviors toward others may have been one of the mechanisms at the basis of altruistic behavioral tendencies in capuchins and in other primates, including humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2764469/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2764469/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paukner, Annika -- Suomi, Stephen J -- Visalberghi, Elisabetta -- Ferrari, Pier F -- Z99 HD999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):880-3. doi: 10.1126/science.1176269.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Comparative Ethology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health Animal Center, Post Office Box 529, Poolesville, MD 20837, USA. pauknera@mail.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679816" target="_blank"〉PubMed〈/a〉

    Description: Working memory is a key function for human cognition, dependent on adequate dopamine neurotransmission. Here we show that the training of working memory, which improves working memory capacity, is associated with changes in the density of cortical dopamine D1 receptors. Fourteen hours of training over 5 weeks was associated with changes in both prefrontal and parietal D1 binding potential. This plasticity of the dopamine D1 receptor system demonstrates a reciprocal interplay between mental activity and brain biochemistry in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNab, Fiona -- Varrone, Andrea -- Farde, Lars -- Jucaite, Aurelija -- Bystritsky, Paulina -- Forssberg, Hans -- Klingberg, Torkel -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):800-2. doi: 10.1126/science.1166102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neuropediatric Unit, Department of Woman and Child Health, Stockholm Brain Institute, Karolinska Institutet, Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197069" target="_blank"〉PubMed〈/a〉

    Description: The Caenorhabditis elegans von Hippel-Lindau tumor suppressor homolog VHL-1 is a cullin E3 ubiquitin ligase that negatively regulates the hypoxic response by promoting ubiquitination and degradation of the hypoxic response transcription factor HIF-1. Here, we report that loss of VHL-1 significantly increased life span and enhanced resistance to polyglutamine and beta-amyloid toxicity. Deletion of HIF-1 was epistatic to VHL-1, indicating that HIF-1 acts downstream of VHL-1 to modulate aging and proteotoxicity. VHL-1 and HIF-1 control longevity by a mechanism distinct from both dietary restriction and insulin-like signaling. These findings define VHL-1 and the hypoxic response as an alternative longevity and protein homeostasis pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2737476/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2737476/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehta, Ranjana -- Steinkraus, Katherine A -- Sutphin, George L -- Ramos, Fresnida J -- Shamieh, Lara S -- Huh, Alexander -- Davis, Christina -- Chandler-Brown, Devon -- Kaeberlein, Matt -- 1R01AG031108-01/AG/NIA NIH HHS/ -- P30AG013280/AG/NIA NIH HHS/ -- R01 AG031108/AG/NIA NIH HHS/ -- R01 AG031108-01A1/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2009 May 29;324(5931):1196-8. doi: 10.1126/science.1173507.

    Description: To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.〈br /〉〈br /〉〈a

    Description: Little is known about the genetic contribution to individual differences in neural networks subserving cognition function. In this functional magnetic resonance imaging (fMRI) twin study, we found a significant genetic influence on brain activation in neural networks supporting digit working memory tasks. Participants activating frontal-parietal networks responded faster than individuals relying more on language-related brain networks. There were genetic influences on brain activation in language-relevant brain circuits that were atypical for numerical working memory tasks as such. This suggests that differences in cognition might be related to brain activation patterns that differ qualitatively among individuals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koten, Jan Willem Jr -- Wood, Guilherme -- Hagoort, Peter -- Goebel, Rainer -- Propping, Peter -- Willmes, Klaus -- Boomsma, Dorret I -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1737-40. doi: 10.1126/science.1167371.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section Neuropsychology, RWTH Aachen University, Germany. jan.koten@gmx.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325117" target="_blank"〉PubMed〈/a〉

    Description: Distinct classes of protective immunity are guided by activation of STAT transcription factor family members in response to environmental cues. CD4+ regulatory T cells (T(regs)) suppress excessive immune responses, and their deficiency results in a lethal, multi-organ autoimmune syndrome characterized by T helper 1 (TH1) and T helper 2 (TH2) CD4+ T cell-dominated lesions. Here we show that pathogenic TH17 responses in mice are also restrained by T(regs). This suppression was lost upon T(reg)-specific ablation of Stat3, a transcription factor critical for TH17 differentiation, and resulted in the development of a fatal intestinal inflammation. These findings suggest that T(regs) adapt to their environment by engaging distinct effector response-specific suppression modalities upon activation of STAT proteins that direct the corresponding class of the immune response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4408196/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4408196/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhry, Ashutosh -- Rudra, Dipayan -- Treuting, Piper -- Samstein, Robert M -- Liang, Yuqiong -- Kas, Arnold -- Rudensky, Alexander Y -- AI-034206/AI/NIAID NIH HHS/ -- AI-061816/AI/NIAID NIH HHS/ -- R01 AI034206/AI/NIAID NIH HHS/ -- R01 AI061816/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):986-91. doi: 10.1126/science.1172702.

    Description: Diminished synaptic inhibition in the spinal dorsal horn is a major contributor to chronic pain. Pathways that reduce synaptic inhibition in inflammatory and neuropathic pain states have been identified, but central hyperalgesia and diminished dorsal horn synaptic inhibition also occur in the absence of inflammation or neuropathy, solely triggered by intense nociceptive (C-fiber) input to the spinal dorsal horn. We found that endocannabinoids, produced upon strong nociceptive stimulation, activated type 1 cannabinoid (CB1) receptors on inhibitory dorsal horn neurons to reduce the synaptic release of gamma-aminobutyric acid and glycine and thus rendered nociceptive neurons excitable by nonpainful stimuli. Our results suggest that spinal endocannabinoids and CB1 receptors on inhibitory dorsal horn interneurons act as mediators of heterosynaptic pain sensitization and play an unexpected role in dorsal horn pain-controlling circuits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2835775/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2835775/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pernia-Andrade, Alejandro J -- Kato, Ako -- Witschi, Robert -- Nyilas, Rita -- Katona, Istvan -- Freund, Tamas F -- Watanabe, Masahiko -- Filitz, Jorg -- Koppert, Wolfgang -- Schuttler, Jurgen -- Ji, Guangchen -- Neugebauer, Volker -- Marsicano, Giovanni -- Lutz, Beat -- Vanegas, Horacio -- Zeilhofer, Hanns Ulrich -- NS11255/NS/NINDS NIH HHS/ -- NS38261/NS/NINDS NIH HHS/ -- P01 NS011255/NS/NINDS NIH HHS/ -- P01 NS011255-32A20042/NS/NINDS NIH HHS/ -- P01 NS011255-330042/NS/NINDS NIH HHS/ -- R01 NS038261/NS/NINDS NIH HHS/ -- R01 NS038261-08/NS/NINDS NIH HHS/ -- R01 NS038261-09/NS/NINDS NIH HHS/ -- R01 NS038261-10/NS/NINDS NIH HHS/ -- R01 NS038261-10S1/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 7;325(5941):760-4. doi: 10.1126/science.1171870.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Pharmacology and Toxicology, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19661434" target="_blank"〉PubMed〈/a〉

    Description: Dual-process theories distinguish between intuition (fast and emotional) and reasoning (slow and controlled) as a basis for human decision-making. We contrast dominance-solvable games, which can be solved by step-by-step deliberative reasoning, with pure coordination games, which must be solved intuitively. Using functional magnetic resonance imaging, we found that the middle frontal gyrus, the inferior parietal lobule, and the precuneus were more active in dominance-solvable games than in coordination games. The insula and anterior cingulate cortex showed the opposite pattern. Moreover, precuneus activity correlates positively with how "effortful" a dominance-solvable game is, whereas insula activity correlates positively with how "effortless" a coordination game is.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuo, Wen-Jui -- Sjostrom, Tomas -- Chen, Yu-Ping -- Wang, Yen-Hsiang -- Huang, Chen-Ying -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):519-22. doi: 10.1126/science.1165598.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neuroscience, National Yang-Ming University, Taipei, Taiwan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390048" target="_blank"〉PubMed〈/a〉

    Description: Pandemic influenza A (H1N1) 2009 (pandemic H1N1) is spreading throughout the planet. It has become the dominant strain in the Southern Hemisphere, where the influenza season has now ended. Here, on the basis of reported case clusters in the United States, we estimated the household secondary attack rate for pandemic H1N1 to be 27.3% [95% confidence interval (CI) from 12.2% to 50.5%]. From a school outbreak, we estimated that a typical schoolchild infects 2.4 (95% CI from 1.8 to 3.2) other children within the school. We estimated the basic reproductive number, R0, to range from 1.3 to 1.7 and the generation interval to range from 2.6 to 3.2 days. We used a simulation model to evaluate the effectiveness of vaccination strategies in the United States for fall 2009. If a vaccine were available soon enough, vaccination of children, followed by adults, reaching 70% overall coverage, in addition to high-risk and essential workforce groups, could mitigate a severe epidemic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880578/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880578/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Yang -- Sugimoto, Jonathan D -- Halloran, M Elizabeth -- Basta, Nicole E -- Chao, Dennis L -- Matrajt, Laura -- Potter, Gail -- Kenah, Eben -- Longini, Ira M Jr -- R01 AI032042/AI/NIAID NIH HHS/ -- R01 AI032042-16/AI/NIAID NIH HHS/ -- R01-AI32042/AI/NIAID NIH HHS/ -- U01 GM070749/GM/NIGMS NIH HHS/ -- U01 GM070749-07/GM/NIGMS NIH HHS/ -- U01-GM070749/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 30;326(5953):729-33. doi: 10.1126/science.1177373.
