    Beschreibung: To test the hypothesis that actin dysfunction leads to heart failure, patients with hereditary idiopathic dilated cardiomyopathy (IDC) were examined for mutations in the cardiac actin gene (ACTC). Missense mutations in ACTC that cosegregate with IDC were identified in two unrelated families. Both mutations affect universally conserved amino acids in domains of actin that attach to Z bands and intercalated discs. Coupled with previous data showing that dystrophin mutations also cause dilated cardiomyopathy, these results raise the possibility that defective transmission of force in cardiac myocytes is a mechanism underlying heart failure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olson, T M -- Michels, V V -- Thibodeau, S N -- Tai, Y S -- Keating, M T -- 5-P50-HL-53773/HL/NHLBI NIH HHS/ -- M01-RR00064/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1998 May 1;280(5364):750-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Division of Cardiology, University of Utah Health Sciences Center, Salt Lake City, UT 84112, USA. timo@howard.genetics.utah.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9563954" target="_blank"〉PubMed〈/a〉

    Beschreibung: Humans show considerable interindividual variation in susceptibility to weight gain in response to overeating. The physiological basis of this variation was investigated by measuring changes in energy storage and expenditure in 16 nonobese volunteers who were fed 1000 kilocalories per day in excess of weight-maintenance requirements for 8 weeks. Two-thirds of the increases in total daily energy expenditure was due to increased nonexercise activity thermogenesis (NEAT), which is associated with fidgeting, maintenance of posture, and other physical activities of daily life. Changes in NEAT accounted for the 10-fold differences in fat storage that occurred and directly predicted resistance to fat gain with overfeeding (correlation coefficient = 0.77, probability 〈 0.001). These results suggest that as humans overeat, activation of NEAT dissipates excess energy to preserve leanness and that failure to activate NEAT may result in ready fat gain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levine, J A -- Eberhardt, N L -- Jensen, M D -- DK45343/DK/NIDDK NIH HHS/ -- DK50456/DK/NIDDK NIH HHS/ -- M01 RR00535/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1999 Jan 8;283(5399):212-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Endocrine Research Unit, Mayo Clinic and Mayo Foundation, 200 First Street Southwest, Rochester, MN 55905, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9880251" target="_blank"〉PubMed〈/a〉

    Beschreibung: Regulation of circadian period in humans was thought to differ from that of other species, with the period of the activity rhythm reported to range from 13 to 65 hours (median 25.2 hours) and the period of the body temperature rhythm reported to average 25 hours in adulthood, and to shorten with age. However, those observations were based on studies of humans exposed to light levels sufficient to confound circadian period estimation. Precise estimation of the periods of the endogenous circadian rhythms of melatonin, core body temperature, and cortisol in healthy young and older individuals living in carefully controlled lighting conditions has now revealed that the intrinsic period of the human circadian pacemaker averages 24.18 hours in both age groups, with a tight distribution consistent with other species. These findings have important implications for understanding the pathophysiology of disrupted sleep in older people.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Czeisler, C A -- Duffy, J F -- Shanahan, T L -- Brown, E N -- Mitchell, J F -- Rimmer, D W -- Ronda, J M -- Silva, E J -- Allan, J S -- Emens, J S -- Dijk, D J -- Kronauer, R E -- MO1-RR02635/RR/NCRR NIH HHS/ -- P01-AG09975/AG/NIA NIH HHS/ -- R01-GM53559/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2177-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Circadian, Neuroendocrine, and Sleep Disorders Section, Division of Endocrinology, Department of Medicine, Harvard Medical School, Brigham and Women's Hospital, 221 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381883" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pig organs may offer a solution to the shortage of human donor organs for transplantation, but concerns remain about possible cross-species transmission of porcine endogenous retrovirus (PERV). Samples were collected from 160 patients who had been treated with various living pig tissues up to 12 years earlier. Reverse transcription-polymerase chain reaction (RT-PCR) and protein immunoblot analyses were performed on serum from all 160 patients. No viremia was detected in any patient. Peripheral blood mononuclear cells from 159 of the patients were analyzed by PCR using PERV-specific primers. No PERV infection was detected in any of the patients from whom sufficient DNA was extracted to allow complete PCR analysis (97 percent of the patients). Persistent microchimerism (presence of donor cells in the recipient) was observed in 23 patients for up to 8.5 years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paradis, K -- Langford, G -- Long, Z -- Heneine, W -- Sandstrom, P -- Switzer, W M -- Chapman, L E -- Lockey, C -- Onions, D -- Otto, E -- New York, N.Y. -- Science. 1999 Aug 20;285(5431):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Imutran Ltd.

    Beschreibung: Does the human capacity for mathematical intuition depend on linguistic competence or on visuo-spatial representations? A series of behavioral and brain-imaging experiments provides evidence for both sources. Exact arithmetic is acquired in a language-specific format, transfers poorly to a different language or to novel facts, and recruits networks involved in word-association processes. In contrast, approximate arithmetic shows language independence, relies on a sense of numerical magnitudes, and recruits bilateral areas of the parietal lobes involved in visuo-spatial processing. Mathematical intuition may emerge from the interplay of these brain systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehaene, S -- Spelke, E -- Pinel, P -- Stanescu, R -- Tsivkin, S -- HD23103/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1999 May 7;284(5416):970-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite INSERM 334, Service Hospitalier Frederic Joliot, CEA/DSV, 91401 Orsay Cedex, France. dehaene@shfj.cea.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10320379" target="_blank"〉PubMed〈/a〉

    Beschreibung: A fundamental question about human memory is which brain structures are involved, and when, in transforming experiences into memories. This experiment sought to identify neural correlates of memory formation with the use of intracerebral electrodes implanted in the brains of patients with temporal lobe epilepsy. Event-related potentials (ERPs) were recorded directly from the medial temporal lobe (MTL) as the patients studied single words. ERPs elicited by words subsequently recalled in a memory test were contrasted with ERPs elicited by unrecalled words. Memory formation was associated with distinct but interrelated ERP differences within the rhinal cortex and the hippocampus, which arose after about 300 and 500 milliseconds, respectively. These findings suggest that declarative memory formation is dissociable into subprocesses and sequentially organized within the MTL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fernandez, G -- Effern, A -- Grunwald, T -- Pezer, N -- Lehnertz, K -- Dumpelmann, M -- Van Roost, D -- Elger, C E -- New York, N.Y. -- Science. 1999 Sep 3;285(5433):1582-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Epileptology, University of Bonn, 53105 Bonn, Germany. gf@mailer.meb.uni-bonn.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10477525" target="_blank"〉PubMed〈/a〉

    Beschreibung: Intervertebral disc disease is one of the most common musculoskeletal disorders. A number of environmental and anthropometric risk factors may contribute to it, and recent reports have suggested the importance of genetic factors as well. The COL9A2 gene, which codes for one of the polypeptide chains of collagen IX that is expressed in the intervertebral disc, was screened for sequence variations in individuals with intervertebral disc disease. The analysis identified a putative disease-causing sequence variation that converted a codon for glutamine to one for tryptophan in six out of the 157 individuals but in none of 174 controls. The tryptophan allele cosegregated with the disease phenotype in the four families studied, giving a lod score (logarithm of odds ratio) for linkage of 4.5, and subsequent linkage disequilibrium analysis conditional on linkage gave an additional lod score of 7.1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Annunen, S -- Paassilta, P -- Lohiniva, J -- Perala, M -- Pihlajamaa, T -- Karppinen, J -- Tervonen, O -- Kroger, H -- Lahde, S -- Vanharanta, H -- Ryhanen, L -- Goring, H H -- Ott, J -- Prockop, D J -- Ala-Kokko, L -- AR39740/AR/NIAMS NIH HHS/ -- HG00008/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 16;285(5426):409-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Collagen Research Unit, Biocenter and Department of Medical Biochemistry, University of Oulu, 90220 Oulu, Finland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10411504" target="_blank"〉PubMed〈/a〉

    Beschreibung: Progressive damage to mitochondrial DNA (mtDNA) during life is thought to contribute to aging processes. However, this idea has been difficult to reconcile with the small fraction of mtDNA so far found to be altered. Here, examination of mtDNA revealed high copy point mutations at specific positions in the control region for replication of human fibroblast mtDNA from normal old, but not young, individuals. Furthermore, in longitudinal studies, one or more mutations appeared in an individual only at an advanced age. Some mutations appeared in more than one individual. Most strikingly, a T414G transversion was found, in a generally high proportion (up to 50 percent) of mtDNA molecules, in 8 of 14 individuals above 65 years of age (57 percent) but was absent in 13 younger individuals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michikawa, Y -- Mazzucchelli, F -- Bresolin, N -- Scarlato, G -- Attardi, G -- AG-12117-03/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1999 Oct 22;286(5440):774-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, 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/10531063" target="_blank"〉PubMed〈/a〉

    Beschreibung: Visual imagery is used in a wide range of mental activities, ranging from memory to reasoning, and also plays a role in perception proper. The contribution of early visual cortex, specifically Area 17, to visual mental imagery was examined by the use of two convergent techniques. In one, subjects closed their eyes during positron emission tomography (PET) while they visualized and compared properties (for example, relative length) of sets of stripes. The results showed that when people perform this task, Area 17 is activated. In the other, repetitive transcranial magnetic stimulation (rTMS) was applied to medial occipital cortex before presentation of the same task. Performance was impaired after rTMS compared with a sham control condition; similar results were obtained when the subjects performed the task by actually looking at the stimuli. In sum, the PET results showed that when patterns of stripes are visualized, Area 17 is activated, and the rTMS results showed that such activation underlies information processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kosslyn, S M -- Pascual-Leone, A -- Felician, O -- Camposano, S -- Keenan, J P -- Thompson, W L -- Ganis, G -- Sukel, K E -- Alpert, N M -- R01 EY12091/EY/NEI NIH HHS/ -- R01 MH57980/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):167-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Harvard University, Cambridge, MA 02138, USA. smk@wjh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102821" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human mesenchymal stem cells are thought to be multipotent cells, which are present in adult marrow, that can replicate as undifferentiated cells and that have the potential to differentiate to lineages of mesenchymal tissues, including bone, cartilage, fat, tendon, muscle, and marrow stroma. Cells that have the characteristics of human mesenchymal stem cells were isolated from marrow aspirates of volunteer donors. These cells displayed a stable phenotype and remained as a monolayer in vitro. These adult stem cells could be induced to differentiate exclusively into the adipocytic, chondrocytic, or osteocytic lineages. Individual stem cells were identified that, when expanded to colonies, retained their multilineage potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pittenger, M F -- Mackay, A M -- Beck, S C -- Jaiswal, R K -- Douglas, R -- Mosca, J D -- Moorman, M A -- Simonetti, D W -- Craig, S -- Marshak, D R -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):143-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Osiris Therapeutics, 2001 Aliceanna Street, Baltimore, MD 21231-3043, USA. mpittenger@osiristx.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102814" target="_blank"〉PubMed〈/a〉

    Beschreibung: The experience of pain is subjectively different from the fear and anxiety caused by threats of pain. Functional magnetic resonance imaging in healthy humans was applied to dissociate neural activation patterns associated with acute pain and its anticipation. Expectation of pain activated sites within the medial frontal lobe, insular cortex, and cerebellum distinct from, but close to, locations mediating pain experience itself.

    Beschreibung: In an associative learning paradigm, human subjects could be divided based on whether they were aware that one tone predicted a visual event and another did not. Only aware subjects acquired a differential behavioral response to the tones. Regional cerebral blood flow in left prefrontal cortex showed learning-related changes only in aware subjects. Left prefrontal cortex also showed changes in functional connectivity with contralateral prefrontal cortex, sensory association cortices, and cerebellum. Several of the interacting areas correlated with aware subjects' behavior. These results suggest cerebral processes underlying awareness are mediated through interactions of large-scale neurocognitive systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McIntosh, A R -- Rajah, M N -- Lobaugh, N J -- New York, N.Y. -- Science. 1999 May 28;284(5419):1531-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rotman Research Institute of Baycrest Centre, 3560 Bathurst Street, Toronto, Ontario M6A 2E1, Canada. mcintosh@psych.utoronto.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10348741" target="_blank"〉PubMed〈/a〉

    Beschreibung: During learning, neural responses decrease over repeated exposure to identical stimuli. This repetition suppression is thought to reflect a progressive optimization of neuronal responses elicited by the task. Functional magnetic resonance imaging was used to study the neural basis of associative learning of visual objects and their locations. As expected, activation in specialized cortical areas decreased with time. However, with path analysis it was shown that, in parallel to this adaptation, increases in effective connectivity occurred between distinct cortical systems specialized for spatial and object processing. The time course of these plastic changes was highly correlated with individual learning performance, suggesting that interactions between brain areas underlie associative learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buchel, C -- Coull, J T -- Friston, K J -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1999 Mar 5;283(5407):1538-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London WC1N 3BG, UK. c.buechel@fil.ion.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10066177" target="_blank"〉PubMed〈/a〉

    Beschreibung: The localization of substance P in brain regions that coordinate stress responses and receive convergent monoaminergic innervation suggested that substance P antagonists might have psychotherapeutic properties. Like clinically used antidepressant and anxiolytic drugs, substance P antagonists suppressed isolation-induced vocalizations in guinea pigs. In a placebo-controlled trial in patients with moderate to severe major depression, robust antidepressant effects of the substance P antagonist MK-869 were consistently observed. In preclinical studies, substance P antagonists did not interact with monoamine systems in the manner seen with established antidepressant drugs. These findings suggest that substance P may play an important role in psychiatric disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kramer, M S -- Cutler, N -- Feighner, J -- Shrivastava, R -- Carman, J -- Sramek, J J -- Reines, S A -- Liu, G -- Snavely, D -- Wyatt-Knowles, E -- Hale, J J -- Mills, S G -- MacCoss, M -- Swain, C J -- Harrison, T -- Hill, R G -- Hefti, F -- Scolnick, E M -- Cascieri, M A -- Chicchi, G G -- Sadowski, S -- Williams, A R -- Hewson, L -- Smith, D -- Carlson, E J -- Hargreaves, R J -- Rupniak, N M -- New York, N.Y. -- Science. 1998 Sep 11;281(5383):1640-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Merck Research Laboratories, West Point, PA 19456, USA.

    Beschreibung: Insulin-like growth factor-I (IGF-I) is a mitogen for prostate epithelial cells. To investigate associations between plasma IGF levels and prostate cancer risk, a nested case-control study within the Physicians' Health Study was conducted on prospectively collected plasma from 152 cases and 152 controls. A strong positive association was observed between IGF-I levels and prostate cancer risk. Men in the highest quartile of IGF-I levels had a relative risk of 4.3 (95 percent confidence interval 1.8 to 10.6) compared with men in the lowest quartile. This association was independent of baseline prostate-specific antigen levels. Identification of plasma IGF-I as a predictor of prostate cancer risk may have implications for risk reduction and treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, J M -- Stampfer, M J -- Giovannucci, E -- Gann, P H -- Ma, J -- Wilkinson, P -- Hennekens, C H -- Pollak, M -- CA-42182/CA/NCI NIH HHS/ -- CA-58684/CA/NCI NIH HHS/ -- T32 CA 09001-20/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1998 Jan 23;279(5350):563-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Epidemiology, Harvard School of Public Health, 677 Huntington Avenue, Boston, MA 02115, USA. jmlchan@hsph.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9438850" target="_blank"〉PubMed〈/a〉

    Beschreibung: The efficacy of a behavioral intervention to reduce human immunodeficiency virus (HIV) risk behaviors was tested in a randomized, controlled trial with three high-risk populations at 37 clinics from seven sites across the United States. Compared with the 1855 individuals in the control condition, the 1851 participants assigned to a small-group, seven-session HIV risk reduction program reported fewer unprotected sexual acts, had higher levels of condom use, and were more likely to use condoms consistently over a 12-month follow-up period. On the basis of clinical record review, no difference in overall sexually transmitted disease (STD) reinfection rate was found between intervention and control condition participants. However, among men recruited from STD clinics, those assigned to the intervention condition had a gonorrhea incidence rate one-half that of those in the control condition. Intervention condition participants also reported fewer STD symptoms over the 12-month follow-up period. Study outcomes suggest that behavioral interventions can reduce HIV-related sexual risk behavior among low-income women and men served in public health settings. Studies that test strategies for reducing sexual risk behavior over longer periods of time are needed, especially with populations that remain most vulnerable to HIV infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉New York, N.Y. -- Science. 1998 Jun 19;280(5371):1889-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9632382" target="_blank"〉PubMed〈/a〉

    Beschreibung: Treatment-resistant Lyme arthritis is associated with immune reactivity to outer surface protein A (OspA) of Borrelia burgdorferi, the agent of Lyme disease, and the major histocompatibility complex class II allele DRB1*0401. The immunodominant epitope of OspA for T helper cells was identified. A homology search revealed a peptide from human leukocyte function-associated antigen-1 (hLFA-1) as a candidate autoantigen. Individuals with treatment-resistant Lyme arthritis, but not other forms of arthritis, generated responses to OspA, hLFA-1, and their highly related peptide epitopes. Identification of the initiating bacterial antigen and a cross-reactive autoantigen may provide a model for development of autoimmune disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gross, D M -- Forsthuber, T -- Tary-Lehmann, M -- Etling, C -- Ito, K -- Nagy, Z A -- Field, J A -- Steere, A C -- Huber, B T -- R01 AR20358/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Jul 31;281(5377):703-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Tufts University, Boston, MA 02111 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9685265" target="_blank"〉PubMed〈/a〉

    Beschreibung: Generation and maintenance of an effective repertoire of T cell antigen receptors are essential to the immune system, yet the number of distinct T cell receptors (TCRs) expressed by the estimated 10(12) T cells in the human body is not known. In this study, TCR gene amplification and sequencing showed that there are about 10(6) different beta chains in the blood, each pairing, on the average, with at least 25 different alpha chains. In the memory subset, the diversity decreased to 1 x 10(5) to 2 x 10(5) different beta chains, each pairing with only a single alpha chain. Thus, the naive repertoire is highly diverse, whereas the memory compartment, here one-third of the T cell population, contributes less than 1 percent of the total diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arstila, T P -- Casrouge, A -- Baron, V -- Even, J -- Kanellopoulos, J -- Kourilsky, P -- New York, N.Y. -- Science. 1999 Oct 29;286(5441):958-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite de Biologie Moleculaire du Gene, INSERM U277, Institut Pasteur, 75724 Paris Cedex 15, France. petteri.arstila@helsinki.fi〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10542151" target="_blank"〉PubMed〈/a〉

    Beschreibung: This study challenges the use of adult neuropsychological models for explaining developmental disorders of genetic origin. When uneven cognitive profiles are found in childhood or adulthood, it is assumed that such phenotypic outcomes characterize infant starting states, and it has been claimed that modules subserving these abilities start out either intact or impaired. Findings from two experiments with infants with Williams syndrome (a phenotype selected to bolster innate modularity claims) indicate a within-syndrome double dissociation: For numerosity judgments, they do well in infancy but poorly in adulthood, whereas for language, they perform poorly in infancy but well in adulthood. The theoretical and clinical implications of these results could lead to a shift in focus for studies of genetic disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paterson, S J -- Brown, J H -- Gsodl, M K -- Johnson, M H -- Karmiloff-Smith, A -- New York, N.Y. -- Science. 1999 Dec 17;286(5448):2355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurocognitive Development Unit, Institute of Child Health, University College, London WC1N 1EH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10600749" target="_blank"〉PubMed〈/a〉

    Beschreibung: The signal transduction events that control the progenitor B cell (pro-B cell) to precursor B cell (pre-B cell) transition have not been well delineated. In evaluating patients with absent B cells, a male with a homozygous splice defect in the cytoplasmic adapter protein BLNK (B cell linker protein) was identified. Although this patient had normal numbers of pro-B cells, he had no pre-B cells or mature B cells, indicating that BLNK plays a critical role in orchestrating the pro-B cell to pre-B cell transition. The immune system and overall growth and development were otherwise normal in this patient, suggesting that BLNK function is highly specific.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Minegishi, Y -- Rohrer, J -- Coustan-Smith, E -- Lederman, H M -- Pappu, R -- Campana, D -- Chan, A C -- Conley, M E -- AI25129/AI/NIAID NIH HHS/ -- AI42787/AI/NIAID NIH HHS/ -- CA71516/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Dec 3;286(5446):1954-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Department of Hematology-Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10583958" target="_blank"〉PubMed〈/a〉

    Beschreibung: A selective advantage against infectious disease associated with increased heterozygosity at the human major histocompatibility complex [human leukocyte antigen (HLA) class I and class II] is believed to play a major role in maintaining the extraordinary allelic diversity of these genes. Maximum HLA heterozygosity of class I loci (A, B, and C) delayed acquired immunodeficiency syndrome (AIDS) onset among patients infected with human immunodeficiency virus-type 1 (HIV-1), whereas individuals who were homozygous for one or more loci progressed rapidly to AIDS and death. The HLA class I alleles B*35 and Cw*04 were consistently associated with rapid development of AIDS-defining conditions in Caucasians. The extended survival of 28 to 40 percent of HIV-1-infected Caucasian patients who avoided AIDS for ten or more years can be attributed to their being fully heterozygous at HLA class I loci, to their lacking the AIDS-associated alleles B*35 and Cw*04, or to both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carrington, M -- Nelson, G W -- Martin, M P -- Kissner, T -- Vlahov, D -- Goedert, J J -- Kaslow, R -- Buchbinder, S -- Hoots, K -- O'Brien, S J -- N01-CO-56000/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Mar 12;283(5408):1748-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Intramural Research Support Program, Science Applications International Corporation Frederick, National Cancer Institute (NCI), Frederick, MD 21702-1201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10073943" target="_blank"〉PubMed〈/a〉

    Beschreibung: Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious stimuli, without changing the perceived intensity. Positron emission tomography revealed significant changes in pain-evoked activity within anterior cingulate cortex, consistent with the encoding of perceived unpleasantness, whereas primary somatosensory cortex activation was unaltered. These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainville, P -- Duncan, G H -- Price, D D -- Carrier, B -- Bushnell, M C -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉D-epartement de Psychologie and Centre de Recherche en Sciences Neurologiques, Universite de Montreal, Montreal, Quebec, Canada H3C 3J7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252330" target="_blank"〉PubMed〈/a〉

    Beschreibung: A basic issue in ecology is the relation between extinction and population size. One of the clearest manifestations of a population threshold for extinction is the critical community size below which infections like measles do not persist. The current generation of stochastic models overestimates the observed critical community size for measles, generating much less persistence of infection than is observed. The inclusion of a more biologically realistic model for the duration of infection produced a much closer fit to the actual critical community size and explains previously undescribed high-frequency oscillations in measles incidence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keeling, M J -- Grenfell, B T -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Jan 3;275(5296):65-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Cambridge CB2 3EJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8974392" target="_blank"〉PubMed〈/a〉

    Beschreibung: What kinds of knowledge underlie the use of language and how is this knowledge acquired? Linguists equate knowing a language with knowing a grammar. Classic "poverty of the stimulus" arguments suggest that grammar identification is an intractable inductive problem and that acquisition is possible only because children possess innate knowledge of grammatical structure. An alternative view is emerging from studies of statistical and probabilistic aspects of language, connectionist models, and the learning capacities of infants. This approach emphasizes continuity between how language is acquired and how it is used. It retains the idea that innate capacities constrain language learning, but calls into question whether they include knowledge of grammatical structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seidenberg, M S -- KO2 01188/PHS HHS/ -- P01 47566/PHS HHS/ -- New York, N.Y. -- Science. 1997 Mar 14;275(5306):1599-603.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neuroscience Program, University of Southern California, Los Angeles, CA 90089-2520, USA. marks@gizmo.usc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9054348" target="_blank"〉PubMed〈/a〉

    Beschreibung: In the early months of life, infants acquire information about the phonetic properties of their native language simply by listening to adults speak. The acoustic properties of phonetic units in language input to young infants in the United States, Russia, and Sweden were examined. In all three countries, mothers addressing their infants produced acoustically more extreme vowels than they did when addressing adults, resulting in a "stretching" of vowel space. The findings show that language input to infants provides exceptionally well-specified information about the linguistic units that form the building blocks for words.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhl, P K -- Andruski, J E -- Chistovich, I A -- Chistovich, L A -- Kozhevnikova, E V -- Ryskina, V L -- Stolyarova, E I -- Sundberg, U -- Lacerda, F -- DC 00520/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1997 Aug 1;277(5326):684-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Speech and Hearing Sciences, University of Washington, Box 357920, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9235890" target="_blank"〉PubMed〈/a〉

To date, however, the genes that encode subunits of this important channel have not been identified. The biophysical properties, sensitivity to pharmacological blockade, and expression pattern of the KCNQ2 and KCNQ3 potassium channels were determined.

    Beschreibung: Type IV bundle-forming pili of enteropathogenic Escherichia coli are required for the localized adherence and autoaggregation phenotypes. Whether these pili are also required for virulence was tested in volunteers by inactivating bfpA or bfpT (perA) encoding, respectively, the pilus subunit and the bfp operon transcriptional activator. Both mutants caused significantly less diarrhea. Mutation of the bfpF nucleotide-binding domain caused increased piliation, enhanced localized adherence, and abolished the twitching motility-dispersal phase of the autoaggregation phenotype. The bfpF mutant colonized the human intestine but was about 200-fold less virulent. Thus, BfpF is required for dispersal from the bacterial aggregate and for full virulence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bieber, D -- Ramer, S W -- Wu, C Y -- Murray, W J -- Tobe, T -- Fernandez, R -- Schoolnik, G K -- 1RO1-AI39521/AI/NIAID NIH HHS/ -- 1RO3-DK52038/DK/NIDDK NIH HHS/ -- MO1-RR00070/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1998 Jun 26;280(5372):2114-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Division of Infectious Diseases and Geographical Medicine, Stanford Program for Vaccine Research, Stanford University Medical Center, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9641917" target="_blank"〉PubMed〈/a〉

    Beschreibung: A typical scene contains many different objects, but the capacity of the visual system to process multiple stimuli at a given time is limited. Thus, attentional mechanisms are required to select relevant objects from among the many objects competing for visual processing. Evidence from functional magnetic resonance imaging (MRI) in humans showed that when multiple stimuli are present simultaneously in the visual field, their cortical representations within the object recognition pathway interact in a competitive, suppressive fashion. Directing attention to one of the stimuli counteracts the suppressive influence of nearby stimuli. This mechanism may serve to filter out irrelevant information in cluttered visual scenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kastner, S -- De Weerd, P -- Desimone, R -- Ungerleider, L G -- New York, N.Y. -- Science. 1998 Oct 2;282(5386):108-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Brain & Cognition, National Institute of Mental Health (NIMH), National Institutes of Health (NIH), Building 49, Room 1B80, Bethesda, MD 20892-4415, USA. sabine@ln.nimh.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9756472" target="_blank"〉PubMed〈/a〉

    Beschreibung: An ultrasound method based on radiation force is presented for imaging the acoustic response of a material to mechanical excitation. Acoustic energy was emitted from solids and tissues in response to an oscillatory radiation force produced by interfering focused beams of ultrasound. Frequency spectra of ultrasound-stimulated acoustic emission exhibited object resonances. Raster-scanning the radiation force over the object and recording the amplitude and phase of the emitted sound resulted in data from which images related to the elastic compositions of the acoustically emitting objects could be computed. Acoustic emission signals distinguished tuning-fork resonances, submillimeter glass spheres, and calcification in excised arteries and detected object motions on the order of nanometers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fatemi, M -- Greenleaf, J F -- New York, N.Y. -- Science. 1998 Apr 3;280(5360):82-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ultrasound Research, Department of Physiology and Biophysics, Mayo Clinic and Mayo Foundation, Rochester, MN 55905, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9525861" target="_blank"〉PubMed〈/a〉

    Beschreibung: cAMP (3',5' cyclic adenosine monophosphate) is a second messenger that in eukaryotic cells induces physiological responses ranging from growth, differentiation, and gene expression to secretion and neurotransmission. Most of these effects have been attributed to the binding of cAMP to cAMP-dependent protein kinase A (PKA). Here, a family of cAMP-binding proteins that are differentially distributed in the mammalian brain and body organs and that exhibit both cAMP-binding and guanine nucleotide exchange factor (GEF) domains is reported. These cAMP-regulated GEFs (cAMP-GEFs) bind cAMP and selectively activate the Ras superfamily guanine nucleotide binding protein Rap1A in a cAMP-dependent but PKA-independent manner. Our findings suggest the need to reformulate concepts of cAMP-mediated signaling to include direct coupling to Ras superfamily signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawasaki, H -- Springett, G M -- Mochizuki, N -- Toki, S -- Nakaya, M -- Matsuda, M -- Housman, D E -- Graybiel, A M -- P01 CA42063/CA/NCI NIH HHS/ -- P01 HL41484/HL/NHLBI NIH HHS/ -- R01 HD28341/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 18;282(5397):2275-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology (MIT), Cambridge, MA, 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9856955" target="_blank"〉PubMed〈/a〉

    Beschreibung: Computational studies suggest that acquisition of a motor skill involves learning an internal model of the dynamics of the task, which enables the brain to predict and compensate for mechanical behavior. During the hours that follow completion of practice, representation of the internal model gradually changes, becoming less fragile with respect to behavioral interference. Here, functional imaging of the brain demonstrates that within 6 hours after completion of practice, while performance remains unchanged, the brain engages new regions to perform the task; there is a shift from prefrontal regions of the cortex to the premotor, posterior parietal, and cerebellar cortex structures. This shift is specific to recall of an established motor skill and suggests that with the passage of time, there is a change in the neural representation of the internal model and that this change may underlie its increased functional stability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shadmehr, R -- Holcomb, H H -- New York, N.Y. -- Science. 1997 Aug 8;277(5327):821-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomedical Engineering, School of Medicine, Johns Hopkins University, 720 Rutland Avenue, 419 Traylor, Baltimore, MD 21205-2195, USA. reza@bme.jhu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9242612" target="_blank"〉PubMed〈/a〉

    Beschreibung: The participation of medial temporal-lobe structures in memory performance was examined by functional magnetic resonance imaging of local blood oxygenation level-dependent signals. Signals were measured during encoding into memory complex scenes or line drawings and during retrieval from memory of previously studied line drawings or words. Encoding tasks yielded increased signals for unfamiliar information in a posterior medial-temporal region that were focused in the parahippocampal cortex. Retrieval tasks yielded increased signals for successfully remembered information in an anterior medial-temporal region that were focused in the subiculum. These results indicate that separate components of the human medial temporal-lobe memory system are active during distinct memory processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabrieli, J D -- Brewer, J B -- Desmond, J E -- Glover, G H -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):264-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Neuroscience Program, Stanford University, Stanford, CA 94305, USA. gabrieli@psych.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9092477" target="_blank"〉PubMed〈/a〉

    Beschreibung: After resection of the corpus callosum, V.J., a left-handed woman with left-hemisphere dominance for spoken language, demonstrated a dissociation between spoken and written language. In the key experiment, words flashed to V.J.'s dominant left hemisphere were easily spoken out loud, but could not be written. However, when the words were flashed to her right hemisphere, she could not speak them out loud, but could write them with her left hand. This marked dissociation supports the view that spoken and written language output can be controlled by independent hemispheres, even though before her hemispheric disconnection, they appeared as inseparable cognitive entities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baynes, K -- Eliassen, J C -- Lutsep, H L -- Gazzaniga, M S -- P01 NS 17778/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1998 May 8;280(5365):902-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, University of California at Davis, Davis, CA 95616, USA. kbaynes@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9572734" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human beings routinely help others to achieve their goals, even when the helper receives no immediate benefit and the person helped is a stranger. Such altruistic behaviors (toward non-kin) are extremely rare evolutionarily, with some theorists even proposing that they are uniquely human. Here we show that human children as young as 18 months of age (prelinguistic or just-linguistic) quite readily help others to achieve their goals in a variety of different situations. This requires both an understanding of others' goals and an altruistic motivation to help. In addition, we demonstrate similar though less robust skills and motivations in three young chimpanzees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warneken, Felix -- Tomasello, Michael -- New York, N.Y. -- Science. 2006 Mar 3;311(5765):1301-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany. warneken@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16513986" target="_blank"〉PubMed〈/a〉

    Beschreibung: How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate the same brain regions irrespective of the language being tested. Here, we reveal that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words. By demonstrating this effect in populations of German-English and Japanese-English bilinguals, we suggest that the left caudate plays a universal role in monitoring and controlling the language in use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crinion, J -- Turner, R -- Grogan, A -- Hanakawa, T -- Noppeney, U -- Devlin, J T -- Aso, T -- Urayama, S -- Fukuyama, H -- Stockton, K -- Usui, K -- Green, D W -- Price, C J -- 051067/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1537-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Imaging Neuroscience, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763154" target="_blank"〉PubMed〈/a〉

    Beschreibung: Few sub-Saharan African countries have witnessed declines in HIV prevalence, and only Uganda has compelling evidence for a decline founded on sexual behavior change. We report a decline in HIV prevalence in eastern Zimbabwe between 1998 and 2003 associated with sexual behavior change in four distinct socioeconomic strata. HIV prevalence fell most steeply at young ages-by 23 and 49%, respectively, among men aged 17 to 29 years and women aged 15 to 24 years-and in more educated groups. Sexually experienced men and women reported reductions in casual sex of 49 and 22%, respectively, whereas recent cohorts reported delayed sexual debut. Selective AIDS-induced mortality contributed to the decline in HIV prevalence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregson, Simon -- Garnett, Geoffrey P -- Nyamukapa, Constance A -- Hallett, Timothy B -- Lewis, James J C -- Mason, Peter R -- Chandiwana, Stephen K -- Anderson, Roy M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):664-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Disease Epidemiology, Imperial College London, UK.

    Beschreibung: Mounting evidence has revealed pathological interactions between HIV and malaria in dually infected patients, but the public health implications of the interplay have remained unclear. A transient almost one-log elevation in HIV viral load occurs during febrile malaria episodes; in addition, susceptibility to malaria is enhanced in HIV-infected patients. A mathematical model applied to a setting in Kenya with an adult population of roughly 200,000 estimated that, since 1980, the disease interaction may have been responsible for 8,500 excess HIV infections and 980,000 excess malaria episodes. Co-infection might also have facilitated the geographic expansion of malaria in areas where HIV prevalence is high. Hence, transient and repeated increases in HIV viral load resulting from recurrent co-infection with malaria may be an important factor in promoting the spread of HIV in sub-Saharan Africa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abu-Raddad, Laith J -- Patnaik, Padmaja -- Kublin, James G -- P30 AI 27757/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1603-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Statistical Center for HIV/AIDS Research and Prevention, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA. laith@scharp.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158329" target="_blank"〉PubMed〈/a〉

    Beschreibung: We observed robust coupling between the high- and low-frequency bands of ongoing electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to 8 hertz) rhythm modulates power in the high gamma (80 to 150 hertz) band of the electrocorticogram, with stronger modulation occurring at higher theta amplitudes. Furthermore, different behavioral tasks evoke distinct patterns of theta/high gamma coupling across the cortex. The results indicate that transient coupling between low- and high-frequency brain rhythms coordinates activity in distributed cortical areas, providing a mechanism for effective communication during cognitive processing in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628289/" 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/PMC2628289/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Canolty, R T -- Edwards, E -- Dalal, S S -- Soltani, M -- Nagarajan, S S -- Kirsch, H E -- Berger, M S -- Barbaro, N M -- Knight, R T -- F31DC006762/DC/NIDCD NIH HHS/ -- NS21135/NS/NINDS NIH HHS/ -- R01 DC004855/DC/NIDCD NIH HHS/ -- R01 DC004855-01A1/DC/NIDCD NIH HHS/ -- R01 NS021135/NS/NINDS NIH HHS/ -- R01 NS021135-20/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1626-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Helen Wills Neuroscience Institute, University of California, Berkeley, CA 94720, USA. rcanolty@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973878" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and to learn from complex feedback (probabilistic learning), play critical roles in activities of daily life. To what extent do different neurochemical systems modulate these two cognitive functions? Here, using stop-signal and probabilistic learning tasks, we show a double dissociation for the involvement of noradrenaline and serotonin in human cognition. In healthy volunteers, inhibition of central noradrenaline reuptake improved response inhibition but had no effect on probabilistic learning, whereas inhibition of central serotonin reuptake impaired probabilistic learning with no effect on response inhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1867315/" 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/PMC1867315/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Samuel R -- Muller, Ulrich -- Blackwell, Andrew D -- Clark, Luke -- Robbins, Trevor W -- Sahakian, Barbara J -- 076274/Wellcome Trust/United Kingdom -- G0001354/Medical Research Council/United Kingdom -- G0401099/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):861-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Cambridge School of Clinical Medicine, Addenbrooke's Hospital, Box 189, Cambridge CB2 2QQ, UK. src33@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469930" target="_blank"〉PubMed〈/a〉

    Beschreibung: The pathophysiology of depression remains enigmatic, although abnormalities in serotonin signaling have been implicated. We have found that the serotonin 1B receptor [5-hydroxytryptamine (5-HT1B) receptor] interacts with p11. p11 increases localization of 5-HT1B receptors at the cell surface. p11 is increased in rodent brains by antidepressants or electroconvulsive therapy, but decreased in an animal model of depression and in brain tissue from depressed patients. Overexpression of p11 increases 5-HT1B receptor function in cells and recapitulates certain behaviors seen after antidepressant treatment in mice. p11 knockout mice exhibit a depression-like phenotype and have reduced responsiveness to 5-HT1B receptor agonists and reduced behavioral reactions to an antidepressant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Svenningsson, Per -- Chergui, Karima -- Rachleff, Ilan -- Flajolet, Marc -- Zhang, Xiaoqun -- El Yacoubi, Malika -- Vaugeois, Jean-Marie -- Nomikos, George G -- Greengard, Paul -- DA10044/DA/NIDA NIH HHS/ -- MH40899/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):77-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400147" target="_blank"〉PubMed〈/a〉

    Beschreibung: Obesity is a heritable trait and a risk factor for many common diseases such as type 2 diabetes, heart disease, and hypertension. We used a dense whole-genome scan of DNA samples from the Framingham Heart Study participants to identify a common genetic variant near the INSIG2 gene associated with obesity. We have replicated the finding in four separate samples composed of individuals of Western European ancestry, African Americans, and children. The obesity-predisposing genotype is present in 10% of individuals. Our study suggests that common genetic polymorphisms are important determinants of obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herbert, Alan -- Gerry, Norman P -- McQueen, Matthew B -- Heid, Iris M -- Pfeufer, Arne -- Illig, Thomas -- Wichmann, H-Erich -- Meitinger, Thomas -- Hunter, David -- Hu, Frank B -- Colditz, Graham -- Hinney, Anke -- Hebebrand, Johannes -- Koberwitz, Kerstin -- Zhu, Xiaofeng -- Cooper, Richard -- Ardlie, Kristin -- Lyon, Helen -- Hirschhorn, Joel N -- Laird, Nan M -- Lenburg, Marc E -- Lange, Christoph -- Christman, Michael F -- CA87969/CA/NCI NIH HHS/ -- K23DK067288/DK/NIDDK NIH HHS/ -- P30DK46200/DK/NIDDK NIH HHS/ -- R01 HD060726/HD/NICHD NIH HHS/ -- R01GM046877/GM/NIGMS NIH HHS/ -- R01HL074166/HL/NHLBI NIH HHS/ -- R01HL54485/HL/NHLBI NIH HHS/ -- R01HL66289/HL/NHLBI NIH HHS/ -- R01MH59532/MH/NIMH NIH HHS/ -- U01HL65899/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 14;312(5771):279-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Genomics, Boston University Medical School, E613, 715 Albany Street, Boston, MA 02118, USA. aherbert@bu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16614226" target="_blank"〉PubMed〈/a〉

    Beschreibung: The study of politics and the life cycle began with a rather single-minded focus on childhood and the family-on the idea, as Tocqueville famously put it, that the entire person could be "seen in the cradle of the child." Politics does begin in childhood, and parents do influence their offspring, but change takes place over the entire span of life. I take up the early emergence of partisanship and essentialism, the formation of generations, politically consequential transitions in adulthood, and the rising of politics and its final decline.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinder, Donald R -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1905-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Political Science, University of Michigan, Ann Arbor, MI 48106, USA. drkinder@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809527" target="_blank"〉PubMed〈/a〉

    Beschreibung: Considerable evidence indicates that a stimulus that is subthreshold, and thus consciously invisible, influences brain activity and behavioral performance. However, it is not clear how subthreshold stimuli are processed in the brain. We found that a task-irrelevant subthreshold coherent motion led to a stronger disturbance in task performance than did suprathreshold motion. With the subthreshold motion, activity in the visual cortex measured by functional magnetic resonance imaging was higher, but activity in the lateral prefrontal cortex was lower, than with suprathreshold motion. These results suggest that subthreshold irrelevant signals are not subject to effective inhibitory control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsushima, Yoshiaki -- Sasaki, Yuka -- Watanabe, Takeo -- P41RR14075/RR/NCRR NIH HHS/ -- R01 EY015980/EY/NEI NIH HHS/ -- R21 EY017737/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Boston University, 64 Cummington Street, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170308" target="_blank"〉PubMed〈/a〉

    Beschreibung: Humans restrain self-interest with moral and social values. They are the only species known to exhibit reciprocal fairness, which implies the punishment of other individuals' unfair behaviors, even if it hurts the punisher's economic self-interest. Reciprocal fairness has been demonstrated in the Ultimatum Game, where players often reject their bargaining partner's unfair offers. Despite progress in recent years, however, little is known about how the human brain limits the impact of selfish motives and implements fair behavior. Here we show that disruption of the right, but not the left, dorsolateral prefrontal cortex (DLPFC) by low-frequency repetitive transcranial magnetic stimulation substantially reduces subjects' willingness to reject their partners' intentionally unfair offers, which suggests that subjects are less able to resist the economic temptation to accept these offers. Importantly, however, subjects still judge such offers as very unfair, which indicates that the right DLPFC plays a key role in the implementation of fairness-related behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knoch, Daria -- Pascual-Leone, Alvaro -- Meyer, Kaspar -- Treyer, Valerie -- Fehr, Ernst -- K24 RR018875/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):829-32.

    Beschreibung: The role of dopamine in monitoring negative action outcomes and feedback-based learning was tested in a neuroimaging study in humans grouped according to the dopamine D2 receptor gene polymorphism DRD2-TAQ-IA. In a probabilistic learning task, A1-allele carriers with reduced dopamine D2 receptor densities learned to avoid actions with negative consequences less efficiently. Their posterior medial frontal cortex (pMFC), involved in feedback monitoring, responded less to negative feedback than others' did. Dynamically changing interactions between pMFC and hippocampus found to underlie feedback-based learning were reduced in A1-allele carriers. This demonstrates that learning from errors requires dopaminergic signaling. Dopamine D2 receptor reduction seems to decrease sensitivity to negative action consequences, which may explain an increased risk of developing addictive behaviors in A1-allele carriers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klein, Tilmann A -- Neumann, Jane -- Reuter, Martin -- Hennig, Jurgen -- von Cramon, D Yves -- Ullsperger, Markus -- R01MH74457/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1642-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany. tklein@cbs.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18063800" target="_blank"〉PubMed〈/a〉

    Beschreibung: Negative associations between birth order and intelligence level have been found in numerous studies. The explanation for this relation is not clear, and several hypotheses have been suggested. One family of hypotheses suggests that the relation is due to more-favorable family interaction and stimulation of low-birth-order children, whereas others claim that the effect is caused by prenatal gestational factors. We show that intelligence quotient (IQ) score levels among nearly 250,000 military conscripts were dependent on social rank in the family and not on birth order as such, providing support for a family interaction explanation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kristensen, Petter -- Bjerkedal, Tor -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1717.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Occupational Health, N-0033 Oslo, Norway. petter.kristensen@stami.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17588924" target="_blank"〉PubMed〈/a〉

    Beschreibung: Whether social comparison affects individual well-being is of central importance for understanding behavior in any social environment. Traditional economic theories focus on the role of absolute rewards, whereas behavioral evidence suggests that social comparisons influence well-being and decisions. We investigated the impact of social comparisons on reward-related brain activity using functional magnetic resonance imaging (fMRI). While being scanned in two adjacent MRI scanners, pairs of subjects had to simultaneously perform a simple estimation task that entailed monetary rewards for correct answers. We show that a variation in the comparison subject's payment affects blood oxygenation level-dependent responses in the ventral striatum. Our results provide neurophysiological evidence for the importance of social comparison on reward processing in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fliessbach, K -- Weber, B -- Trautner, P -- Dohmen, T -- Sunde, U -- Elger, C E -- Falk, A -- New York, N.Y. -- Science. 2007 Nov 23;318(5854):1305-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Life and Brain Center Bonn, Department of NeuroCognition and Clinic of Epileptology, Bonn, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18033886" target="_blank"〉PubMed〈/a〉

    Beschreibung: Obesity is a serious international health problem that increases the risk of several common diseases. The genetic factors predisposing to obesity are poorly understood. A genome-wide search for type 2 diabetes-susceptibility genes identified a common variant in the FTO (fat mass and obesity associated) gene that predisposes to diabetes through an effect on body mass index (BMI). An additive association of the variant with BMI was replicated in 13 cohorts with 38,759 participants. The 16% of adults who are homozygous for the risk allele weighed about 3 kilograms more and had 1.67-fold increased odds of obesity when compared with those not inheriting a risk allele. This association was observed from age 7 years upward and reflects a specific increase in fat mass.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646098/" 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/PMC2646098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frayling, Timothy M -- Timpson, Nicholas J -- Weedon, Michael N -- Zeggini, Eleftheria -- Freathy, Rachel M -- Lindgren, Cecilia M -- Perry, John R B -- Elliott, Katherine S -- Lango, Hana -- Rayner, Nigel W -- Shields, Beverley -- Harries, Lorna W -- Barrett, Jeffrey C -- Ellard, Sian -- Groves, Christopher J -- Knight, Bridget -- Patch, Ann-Marie -- Ness, Andrew R -- Ebrahim, Shah -- Lawlor, Debbie A -- Ring, Susan M -- Ben-Shlomo, Yoav -- Jarvelin, Marjo-Riitta -- Sovio, Ulla -- Bennett, Amanda J -- Melzer, David -- Ferrucci, Luigi -- Loos, Ruth J F -- Barroso, Ines -- Wareham, Nicholas J -- Karpe, Fredrik -- Owen, Katharine R -- Cardon, Lon R -- Walker, Mark -- Hitman, Graham A -- Palmer, Colin N A -- Doney, Alex S F -- Morris, Andrew D -- Smith, George Davey -- Hattersley, Andrew T -- McCarthy, Mark I -- 079557/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- G0000934/Medical Research Council/United Kingdom -- G0500070/Medical Research Council/United Kingdom -- G0600705/Medical Research Council/United Kingdom -- G9815508/Medical Research Council/United Kingdom -- MC_U106179471/Medical Research Council/United Kingdom -- MC_U106188470/Medical Research Council/United Kingdom -- Z99 AG999999/Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 May 11;316(5826):889-94.

    Beschreibung: Resistance to certain scientific ideas derives in large part from assumptions and biases that can be demonstrated experimentally in young children and that may persist into adulthood. In particular, both adults and children resist acquiring scientific information that clashes with common-sense intuitions about the physical and psychological domains. Additionally, when learning information from other people, both adults and children are sensitive to the trustworthiness of the source of that information. Resistance to science, then, is particularly exaggerated in societies where nonscientific ideologies have the advantages of being both grounded in common sense and transmitted by trustworthy sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bloom, Paul -- Weisberg, Deena Skolnick -- New York, N.Y. -- Science. 2007 May 18;316(5827):996-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Yale University, New Haven, CT 06520, USA. paul.bloom@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17510356" target="_blank"〉PubMed〈/a〉

    Beschreibung: Humans normally experience the conscious self as localized within their bodily borders. This spatial unity may break down in certain neurological conditions such as out-of-body experiences, leading to a striking disturbance of bodily self-consciousness. On the basis of these clinical data, we designed an experiment that uses conflicting visual-somatosensory input in virtual reality to disrupt the spatial unity between the self and the body. We found that during multisensory conflict, participants felt as if a virtual body seen in front of them was their own body and mislocalized themselves toward the virtual body, to a position outside their bodily borders. Our results indicate that spatial unity and bodily self-consciousness can be studied experimentally and are based on multisensory and cognitive processing of bodily information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenggenhager, Bigna -- Tadi, Tej -- Metzinger, Thomas -- Blanke, Olaf -- New York, N.Y. -- Science. 2007 Aug 24;317(5841):1096-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cognitive Neuroscience, Ecole Polytechnique Federale de Lausanne, Station 15, 1015 Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17717189" target="_blank"〉PubMed〈/a〉

    Beschreibung: Herbert et al. (Reports, 14 April 2006, p. 279) found that the rs7566605 genetic variant, located upstream of the INSIG2 gene, was consistently associated with increased body mass index. However, we found no evidence of association between rs7566605 and body mass index in two large ethnically homogeneous population-based cohorts. On the contrary, an opposite tendency was observed.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2719286/" 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/PMC2719286/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loos, Ruth J F -- Barroso, Ines -- O'rahilly, Stephen -- Wareham, Nicholas J -- 077016/Wellcome Trust/United Kingdom -- G9824984/Medical Research Council/United Kingdom -- MC_U106179471/Medical Research Council/United Kingdom -- MC_U106188470/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Jan 12;315(5809):187; author reply 187.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Epidemiology Unit, Cambridge, UK. ruth.loos@mrc-epid.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17218509" target="_blank"〉PubMed〈/a〉

    Beschreibung: Whether memories can be suppressed has been a controversial issue in psychology and cognitive neuroscience for decades. We found evidence that emotional memories are suppressed via two time-differentiated neural mechanisms: (i) an initial suppression by the right inferior frontal gyrus over regions supporting sensory components of the memory representation (visual cortex, thalamus), followed by (ii) right medial frontal gyrus control over regions supporting multimodal and emotional components of the memory representation (hippocampus, amygdala), both of which are influenced by fronto-polar regions. These results indicate that memory suppression does occur and, at least in nonpsychiatric populations, is under the control of prefrontal regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Depue, Brendan E -- Curran, Tim -- Banich, Marie T -- New York, N.Y. -- Science. 2007 Jul 13;317(5835):215-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Colorado, Boulder, CO 80309, USA. depue@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17626877" target="_blank"〉PubMed〈/a〉

    Beschreibung: People typically exhibit greater sensitivity to losses than to equivalent gains when making decisions. We investigated neural correlates of loss aversion while individuals decided whether to accept or reject gambles that offered a 50/50 chance of gaining or losing money. A broad set of areas (including midbrain dopaminergic regions and their targets) showed increasing activity as potential gains increased. Potential losses were represented by decreasing activity in several of these same gain-sensitive areas. Finally, individual differences in behavioral loss aversion were predicted by a measure of neural loss aversion in several regions, including the ventral striatum and prefrontal cortex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tom, Sabrina M -- Fox, Craig R -- Trepel, Christopher -- Poldrack, Russell A -- P20 RR020750/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 26;315(5811):515-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of California Los Angeles (UCLA), Franz Hall, Box 951563, Los Angeles, CA 90095-1563, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17255512" target="_blank"〉PubMed〈/a〉

    Beschreibung: A paradigm shift is occurring in the field of primary immunodeficiencies, with revision of the definition of these conditions and a considerable expansion of their limits. Inborn errors of immunity were initially thought to be confined to a few rare, familial, monogenic, recessive traits impairing the development or function of one or several leukocyte subsets and resulting in multiple, recurrent, opportunistic, and fatal infections in infancy. A growing number of exceptions to each of these conventional qualifications have gradually accumulated. It now appears that most individuals suffer from at least one of a multitude of primary immunodeficiencies, the dissection of which is helping to improve human medicine while describing immunity in natura.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Casanova, Jean-Laurent -- Abel, Laurent -- New York, N.Y. -- Science. 2007 Aug 3;317(5838):617-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Human Genetics of Infectious Diseases, Institut National de la Sante et de la Recherche Medicale, U550, Paris, France. casanova@necker.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17673650" target="_blank"〉PubMed〈/a〉

    Beschreibung: Coronary artery disease (CAD) is the leading cause of death worldwide and is commonly caused by a constellation of risk factors called the metabolic syndrome. We characterized a family with autosomal dominant early CAD, features of the metabolic syndrome (hyperlipidemia, hypertension, and diabetes), and osteoporosis. These traits showed genetic linkage to a short segment of chromosome 12p, in which we identified a missense mutation in LRP6, which encodes a co-receptor in the Wnt signaling pathway. The mutation, which substitutes cysteine for arginine at a highly conserved residue of an epidermal growth factor-like domain, impairs Wnt signaling in vitro. These results link a single gene defect in Wnt signaling to CAD and multiple cardiovascular risk factors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2945222/" 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/PMC2945222/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mani, Arya -- Radhakrishnan, Jayaram -- Wang, He -- Mani, Alaleh -- Mani, Mohammad-Ali -- Nelson-Williams, Carol -- Carew, Khary S -- Mane, Shrikant -- Najmabadi, Hossein -- Wu, Dan -- Lifton, Richard P -- K08 HD041481/HD/NICHD NIH HHS/ -- K08 HD041481-01/HD/NICHD NIH HHS/ -- P01DK68229/DK/NIDDK NIH HHS/ -- P50 HL55007/HL/NHLBI NIH HHS/ -- R01 AR051476/AR/NIAMS NIH HHS/ -- R01 AR051476-01A1/AR/NIAMS NIH HHS/ -- R01 AR051476-02/AR/NIAMS NIH HHS/ -- R01 AR051476-03/AR/NIAMS NIH HHS/ -- R01 AR051476-04/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 2;315(5816):1278-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Howard Hughes Medical Institute and Yale University School of Medicine, New Haven, CT 06510, USA. arya.mani@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17332414" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mapping of numbers onto space is fundamental to measurement and to mathematics. Is this mapping a cultural invention or a universal intuition shared by all humans regardless of culture and education? We probed number-space mappings in the Mundurucu, an Amazonian indigene group with a reduced numerical lexicon and little or no formal education. At all ages, the Mundurucu mapped symbolic and nonsymbolic numbers onto a logarithmic scale, whereas Western adults used linear mapping with small or symbolic numbers and logarithmic mapping when numbers were presented nonsymbolically under conditions that discouraged counting. This indicates that the mapping of numbers onto space is a universal intuition and that this initial intuition of number is logarithmic. The concept of a linear number line appears to be a cultural invention that fails to develop in the absence of formal education.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2610411/" 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/PMC2610411/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehaene, Stanislas -- Izard, Veronique -- Spelke, Elizabeth -- Pica, Pierre -- New York, N.Y. -- Science. 2008 May 30;320(5880):1217-20. doi: 10.1126/science.1156540.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, Cognitive Neuro-imaging Unit, Institut Federatif de Recherche (IFR) 49, Gif sur Yvette, France. stanislas.dehaene@cea.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18511690" target="_blank"〉PubMed〈/a〉

    Beschreibung: Process-specific training can improve performance on untrained tasks, but the magnitude of gain is variable and often there is no transfer at all. We demonstrate transfer to a 3-back test of working memory after 5 weeks of training in updating. The transfer effect was based on a joint training-related activity increase for the criterion (letter memory) and transfer tasks in a striatal region that also was recruited pretraining. No transfer was observed to a task that did not engage updating and striatal regions, and age-related striatal changes imposed constraints on transfer. These findings indicate that transfer can occur if the criterion and transfer tasks engage specific overlapping processing components and brain regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dahlin, Erika -- Neely, Anna Stigsdotter -- Larsson, Anne -- Backman, Lars -- Nyberg, Lars -- New York, N.Y. -- Science. 2008 Jun 13;320(5882):1510-2. doi: 10.1126/science.1155466.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Medical Biology, Umea University, 90187 Umea, Sweden. erika.dahlin@physiol.umu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18556560" target="_blank"〉PubMed〈/a〉

    Beschreibung: Current theories hypothesize that dopamine neuronal firing encodes reward prediction errors. Although studies in nonhuman species provide direct support for this theory, functional magnetic resonance imaging (fMRI) studies in humans have focused on brain areas targeted by dopamine neurons [ventral striatum (VStr)] rather than on brainstem dopaminergic nuclei [ventral tegmental area (VTA) and substantia nigra]. We used fMRI tailored to directly image the brainstem. When primary rewards were used in an experiment, the VTA blood oxygen level-dependent (BOLD) response reflected a positive reward prediction error, whereas the VStr encoded positive and negative reward prediction errors. When monetary gains and losses were used, VTA BOLD responses reflected positive reward prediction errors modulated by the probability of winning. We detected no significant VTA BOLD response to nonrewarding events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉D'Ardenne, Kimberlee -- McClure, Samuel M -- Nystrom, Leigh E -- Cohen, Jonathan D -- F32 MH072141/MH/NIMH NIH HHS/ -- P50 MH062196/MH/NIMH NIH HHS/ -- T32 MH065214/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1264-7. doi: 10.1126/science.1150605.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Princeton University, Princeton, NJ 08544, USA. dardenne@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18309087" target="_blank"〉PubMed〈/a〉

    Beschreibung: Glioblastoma multiforme (GBM) is the most common and lethal type of brain cancer. To identify the genetic alterations in GBMs, we sequenced 20,661 protein coding genes, determined the presence of amplifications and deletions using high-density oligonucleotide arrays, and performed gene expression analyses using next-generation sequencing technologies in 22 human tumor samples. This comprehensive analysis led to the discovery of a variety of genes that were not known to be altered in GBMs. Most notably, we found recurrent mutations in the active site of isocitrate dehydrogenase 1 (IDH1) in 12% of GBM patients. Mutations in IDH1 occurred in a large fraction of young patients and in most patients with secondary GBMs and were associated with an increase in overall survival. These studies demonstrate the value of unbiased genomic analyses in the characterization of human brain cancer and identify a potentially useful genetic alteration for the classification and targeted therapy of GBMs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820389/" 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/PMC2820389/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, D Williams -- Jones, Sian -- Zhang, Xiaosong -- Lin, Jimmy Cheng-Ho -- Leary, Rebecca J -- Angenendt, Philipp -- Mankoo, Parminder -- Carter, Hannah -- Siu, I-Mei -- Gallia, Gary L -- Olivi, Alessandro -- McLendon, Roger -- Rasheed, B Ahmed -- Keir, Stephen -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Busam, Dana A -- Tekleab, Hanna -- Diaz, Luis A Jr -- Hartigan, James -- Smith, Doug R -- Strausberg, Robert L -- Marie, Suely Kazue Nagahashi -- Shinjo, Sueli Mieko Oba -- Yan, Hai -- Riggins, Gregory J -- Bigner, Darell D -- Karchin, Rachel -- Papadopoulos, Nick -- Parmigiani, Giovanni -- Vogelstein, Bert -- Velculescu, Victor E -- Kinzler, Kenneth W -- 5P50-NS-20023/NS/NINDS NIH HHS/ -- CA09547/CA/NCI NIH HHS/ -- CA108786/CA/NCI NIH HHS/ -- CA11898/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- NS052507/NS/NINDS NIH HHS/ -- P50 CA062924/CA/NCI NIH HHS/ -- P50 CA062924-160017/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-04/CA/NCI NIH HHS/ -- R01 CA140316/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37 CA043460-27/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-13/CA/NCI NIH HHS/ -- R37 CA057345-17/CA/NCI NIH HHS/ -- R37 CA057345-18/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1807-12. doi: 10.1126/science.1164382.

    Beschreibung: To sustain or repair cooperation during a social exchange, adaptive creatures must understand social gestures and the consequences when shared expectations about fair exchange are violated by accident or intent. We recruited 55 individuals afflicted with borderline personality disorder (BPD) to play a multiround economic exchange game with healthy partners. Behaviorally, individuals with BPD showed a profound incapacity to maintain cooperation, and were impaired in their ability to repair broken cooperation on the basis of a quantitative measure of coaxing. Neurally, activity in the anterior insula, a region known to respond to norm violations across affective, interoceptive, economic, and social dimensions, strongly differentiated healthy participants from individuals with BPD. Healthy subjects showed a strong linear relation between anterior insula response and both magnitude of monetary offer received from their partner (input) and the amount of money repaid to their partner (output). In stark contrast, activity in the anterior insula of BPD participants was related only to the magnitude of repayment sent back to their partner (output), not to the magnitude of offers received (input). These neural and behavioral data suggest that norms used in perception of social gestures are pathologically perturbed or missing altogether among individuals with BPD. This game-theoretic approach to psychopathology may open doors to new ways of characterizing and studying a range of mental illnesses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4105006/" 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/PMC4105006/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King-Casas, Brooks -- Sharp, Carla -- Lomax-Bream, Laura -- Lohrenz, Terry -- Fonagy, Peter -- Montague, P Read -- DA11723/DA/NIDA NIH HHS/ -- F32 MH078485/MH/NIMH NIH HHS/ -- MH078485/MH/NIMH NIH HHS/ -- MH52797/MH/NIMH NIH HHS/ -- NS045790/NS/NINDS NIH HHS/ -- R01 DA011723/DA/NIDA NIH HHS/ -- R01 MH052797/MH/NIMH NIH HHS/ -- R01 NS045790/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):806-10. doi: 10.1126/science.1156902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computational Psychiatry Unit and Department of Neuroscience, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687957" target="_blank"〉PubMed〈/a〉

    Beschreibung: Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. We hypothesize that individually rare structural variants contribute to the illness. Microdeletions and microduplications 〉100 kilobases were identified by microarray comparative genomic hybridization of genomic DNA from 150 individuals with schizophrenia and 268 ancestry-matched controls. All variants were validated by high-resolution platforms. Novel deletions and duplications of genes were present in 5% of controls versus 15% of cases and 20% of young-onset cases, both highly significant differences. The association was independently replicated in patients with childhood-onset schizophrenia as compared with their parents. Mutations in cases disrupted genes disproportionately from signaling networks controlling neurodevelopment, including neuregulin and glutamate pathways. These results suggest that multiple, individually rare mutations altering genes in neurodevelopmental pathways contribute to schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walsh, Tom -- McClellan, Jon M -- McCarthy, Shane E -- Addington, Anjene M -- Pierce, Sarah B -- Cooper, Greg M -- Nord, Alex S -- Kusenda, Mary -- Malhotra, Dheeraj -- Bhandari, Abhishek -- Stray, Sunday M -- Rippey, Caitlin F -- Roccanova, Patricia -- Makarov, Vlad -- Lakshmi, B -- Findling, Robert L -- Sikich, Linmarie -- Stromberg, Thomas -- Merriman, Barry -- Gogtay, Nitin -- Butler, Philip -- Eckstrand, Kristen -- Noory, Laila -- Gochman, Peter -- Long, Robert -- Chen, Zugen -- Davis, Sean -- Baker, Carl -- Eichler, Evan E -- Meltzer, Paul S -- Nelson, Stanley F -- Singleton, Andrew B -- Lee, Ming K -- Rapoport, Judith L -- King, Mary-Claire -- Sebat, Jonathan -- HD043569/HD/NICHD NIH HHS/ -- M01 RR000046/RR/NCRR NIH HHS/ -- MH061355/MH/NIMH NIH HHS/ -- MH061464/MH/NIMH NIH HHS/ -- MH061528/MH/NIMH NIH HHS/ -- NS052108/NS/NINDS NIH HHS/ -- R01 HD043569/HD/NICHD NIH HHS/ -- RR000046/RR/NCRR NIH HHS/ -- RR025014/RR/NCRR NIH HHS/ -- U01 MH061355/MH/NIMH NIH HHS/ -- U01 MH061464/MH/NIMH NIH HHS/ -- U01 MH061528/MH/NIMH NIH HHS/ -- U24 NS052108/NS/NINDS NIH HHS/ -- UL1 RR025014/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):539-43. doi: 10.1126/science.1155174.

    Beschreibung: Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disorder characterized pathologically by ubiquitinated TAR DNA binding protein (TDP-43) inclusions. The function of TDP-43 in the nervous system is uncertain, and a mechanistic role in neurodegeneration remains speculative. We identified neighboring mutations in a highly conserved region of TARDBP in sporadic and familial ALS cases. TARDBPM337V segregated with disease within one kindred and a genome-wide scan confirmed that linkage was restricted to chromosome 1p36, which contains the TARDBP locus. Mutant forms of TDP-43 fragmented in vitro more readily than wild type and, in vivo, caused neural apoptosis and developmental delay in the chick embryo. Our evidence suggests a pathophysiological link between TDP-43 and ALS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sreedharan, Jemeen -- Blair, Ian P -- Tripathi, Vineeta B -- Hu, Xun -- Vance, Caroline -- Rogelj, Boris -- Ackerley, Steven -- Durnall, Jennifer C -- Williams, Kelly L -- Buratti, Emanuele -- Baralle, Francisco -- de Belleroche, Jacqueline -- Mitchell, J Douglas -- Leigh, P Nigel -- Al-Chalabi, Ammar -- Miller, Christopher C -- Nicholson, Garth -- Shaw, Christopher E -- G0500289/Medical Research Council/United Kingdom -- G0501573/Medical Research Council/United Kingdom -- G0600974/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1668-72. doi: 10.1126/science.1154584.

    Beschreibung: "Warmth" is the most powerful personality trait in social judgment, and attachment theorists have stressed the importance of warm physical contact with caregivers during infancy for healthy relationships in adulthood. Intriguingly, recent research in humans points to the involvement of the insula in the processing of both physical temperature and interpersonal warmth (trust) information. Accordingly, we hypothesized that experiences of physical warmth (or coldness) would increase feelings of interpersonal warmth (or coldness), without the person's awareness of this influence. In study 1, participants who briefly held a cup of hot (versus iced) coffee judged a target person as having a "warmer" personality (generous, caring); in study 2, participants holding a hot (versus cold) therapeutic pad were more likely to choose a gift for a friend instead of for themselves.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2737341/" 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/PMC2737341/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Lawrence E -- Bargh, John A -- MH-R01-60767/MH/NIMH NIH HHS/ -- R01 MH060767-09/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Oct 24;322(5901):606-7. doi: 10.1126/science.1162548.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Leeds School of Business, University of Colorado at Boulder, UCB 419, Boulder, CO, 80309-0419, USA. lawrence.williams@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948544" target="_blank"〉PubMed〈/a〉

    Beschreibung: The control of innate immune responses through activation of the nuclear transcription factor NF-kappaB is essential for the elimination of invading microbial pathogens. We showed that the bacterial N-(3-oxo-dodecanoyl) homoserine lactone (C12) selectively impairs the regulation of NF-kappaB functions in activated mammalian cells. The consequence is specific repression of stimulus-mediated induction of NF-kappaB-responsive genes encoding inflammatory cytokines and other immune regulators. These findings uncover a strategy by which C12-producing opportunistic pathogens, such as Pseudomonas aeruginosa, attenuate the innate immune system to establish and maintain local persistent infection in humans, for example, in cystic fibrosis patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kravchenko, Vladimir V -- Kaufmann, Gunnar F -- Mathison, John C -- Scott, David A -- Katz, Alexander Z -- Grauer, David C -- Lehmann, Mandy -- Meijler, Michael M -- Janda, Kim D -- Ulevitch, Richard J -- New York, N.Y. -- Science. 2008 Jul 11;321(5886):259-63. doi: 10.1126/science.1156499.

    Beschreibung: Our ability to remember what we have seen is very limited. Most current views characterize this limit as a fixed number of items-only four objects-that can be held in visual working memory. We show that visual memory capacity is not fixed by the number of objects, but rather is a limited resource that is shared out dynamically between all items in the visual scene. This resource can be shifted flexibly between objects, with allocation biased by selective attention and toward targets of upcoming eye movements. The proportion of resources allocated to each item determines the precision with which it is remembered, a relation that we show is governed by a simple power law, allowing quantitative estimates of resource distribution in a scene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2532743/" 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/PMC2532743/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bays, Paul M -- Husain, Masud -- 061140/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):851-4. doi: 10.1126/science.1158023.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cognitive Neuroscience, University College London, 17 Queen Square, London WC1N 3AR, UK. p.bays@ion.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687968" target="_blank"〉PubMed〈/a〉
