    Description: Interfacially active block copolymer amphiphiles have been synthesized and their self-assembly into micelles in supercritical carbon dioxide (CO2) has been demonstrated with small-angle neutron scattering (SANS). These materials establish the design criteria for molecularly engineered surfactants that can stabilize and disperse otherwise insoluble matter into a CO2 continuous phase. Polystyrene-b-poly(1,1-dihydroperfluorooctyl acrylate) copolymers self-assembled into polydisperse core-shell-type micelles as a result of the disparate solubility characteristics of the different block segments in CO2. These nonionic surfactants for CO2 were shown by SANS to be capable of emulsifying up to 20 percent by weight of a CO2-insoluble hydrocarbon into CO2. This result demonstrates the efficacy of surfactant-modified CO2 in reducing the large volumes of organic and halogenated solvent waste streams released into our environment by solvent-intensive manufacturing and process industries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McClain -- Betts -- Canelas -- Samulski -- DeSimone -- Londono -- Cochran -- Wignall -- Chillura-Martino -- Triolo -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2049-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.

    Description: The complete nucleotide sequence (580,070 base pairs) of the Mycoplasma genitalium genome, the smallest known genome of any free-living organism, has been determined by whole-genome random sequencing and assembly. A total of only 470 predicted coding regions were identified that include genes required for DNA replication, transcription and translation, DNA repair, cellular transport, and energy metabolism. Comparison of this genome to that of Haemophilus influenzae suggests that differences in genome content are reflected as profound differences in physiology and metabolic capacity between these two organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fraser, C M -- Gocayne, J D -- White, O -- Adams, M D -- Clayton, R A -- Fleischmann, R D -- Bult, C J -- Kerlavage, A R -- Sutton, G -- Kelley, J M -- Fritchman, R D -- Weidman, J F -- Small, K V -- Sandusky, M -- Fuhrmann, J -- Nguyen, D -- Utterback, T R -- Saudek, D M -- Phillips, C A -- Merrick, J M -- Tomb, J F -- Dougherty, B A -- Bott, K F -- Hu, P C -- Lucier, T S -- Peterson, S N -- Smith, H O -- Hutchison, C A 3rd -- Venter, J C -- AI33161/AI/NIAID NIH HHS/ -- AIO8998/AI/NIAID NIH HHS/ -- HL19171/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Oct 20;270(5235):397-403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569993" target="_blank"〉PubMed〈/a〉

    Description: A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus. When inoculated into six cattle and two swine, this protein elicited high levels of neutralizing antibody and protection against challenge with foot-and-mouth disease virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleid, D G -- Yansura, D -- Small, B -- Dowbenko, D -- Moore, D M -- Grubman, M J -- McKercher, P D -- Morgan, D O -- Robertson, B H -- Bachrach, H L -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1125-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272395" target="_blank"〉PubMed〈/a〉

    Description: New particle formation in a tropical marine boundary layer setting was characterized during NASA's Pacific Exploratory Mission-Tropics A program. It represents the clearest demonstration to date of aerosol nucleation and growth being linked to the natural marine sulfur cycle. This conclusion was based on real-time observations of dimethylsulfide, sulfur dioxide, sulfuric acid (gas), hydroxide, ozone, temperature, relative humidity, aerosol size and number distribution, and total aerosol surface area. Classic binary nucleation theory predicts no nucleation under the observed marine boundary layer conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clarke -- Davis -- Kapustin -- Eisele -- Chen -- Paluch I -- Lenschow -- Bandy -- Thornton -- Moore -- Mauldin -- Tanner -- Litchy -- Carroll -- Collins -- Albercook -- New York, N.Y. -- Science. 1998 Oct 2;282(5386):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉A.

    Description: The pathogenesis of asthma reflects, in part, the activity of T cell cytokines. Murine models support participation of interleukin-4 (IL-4) and the IL-4 receptor in asthma. Selective neutralization of IL-13, a cytokine related to IL-4 that also binds to the alpha chain of the IL-4 receptor, ameliorated the asthma phenotype, including airway hyperresponsiveness, eosinophil recruitment, and mucus overproduction. Administration of either IL-13 or IL-4 conferred an asthma-like phenotype to nonimmunized T cell-deficient mice by an IL-4 receptor alpha chain-dependent pathway. This pathway may underlie the genetic associations of asthma with both the human 5q31 locus and the IL-4 receptor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3897229/" 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/PMC3897229/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grunig, G -- Warnock, M -- Wakil, A E -- Venkayya, R -- Brombacher, F -- Rennick, D M -- Sheppard, D -- Mohrs, M -- Donaldson, D D -- Locksley, R M -- Corry, D B -- 03344/PHS HHS/ -- 47412/PHS HHS/ -- K08 HL003344/HL/NHLBI NIH HHS/ -- T32 HL07185/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1998 Dec 18;282(5397):2261-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, San Francisco General Hospital, University of California San Francisco, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9856950" target="_blank"〉PubMed〈/a〉

    Description: Recent advances in developing nonlinear optical techniques for processing serial digital information at high speed are reviewed. The field has been transformed by the advent of semiconductor nonlinear devices capable of operation at 100 gigabits per second and higher, well beyond the current speed limits of commercial electronics. These devices are expected to become important in future high-capacity communications networks by allowing digital regeneration and other processing functions to be performed on data signals "on the fly" in the optical domain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cotter -- Manning -- Blow -- Ellis -- Kelly -- Nesset -- Phillips -- Poustie -- Rogers -- New York, N.Y. -- Science. 1999 Nov 19;286(5444):1523-1528.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BT Advanced Communications Technology Centre, Adastral Park, Martlesham Heath, Ipswich IP5 3RE, United Kingdom.

    Description: Estrogen receptor alpha transcriptional activity is regulated by distinct conformational states that are the result of ligand binding. Phage display was used to identify peptides that interact specifically with either estradiol- or tamoxifen-activated estrogen receptor alpha. When these peptides were coexpressed with estrogen receptor alpha in cells, they functioned as ligand-specific antagonists, indicating that estradiol-agonist and tamoxifen-partial agonist activities do not occur by the same mechanism. The ability to regulate estrogen receptor alpha transcriptional activity by targeting sites outside of the ligand-binding pocket has implications for the development of estrogen receptor alpha antagonists for the treatment of tamoxifen-refractory breast cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Norris, J D -- Paige, L A -- Christensen, D J -- Chang, C Y -- Huacani, M R -- Fan, D -- Hamilton, P T -- Fowlkes, D M -- McDonnell, D P -- DK48807/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):744-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Duke University Medical Center, Department of Pharmacology and Cancer Biology, Durham, NC 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10426998" target="_blank"〉PubMed〈/a〉

    Description: Motilin is a 22-amino acid peptide hormone expressed throughout the gastrointestinal (GI) tract of humans and other species. It affects gastric motility by stimulating interdigestive antrum and duodenal contractions. A heterotrimeric guanosine triphosphate-binding protein (G protein)-coupled receptor for motilin was isolated from human stomach, and its amino acid sequence was found to be 52 percent identical to the human receptor for growth hormone secretagogues. The macrolide antibiotic erythromycin also interacted with the cloned motilin receptor, providing a molecular basis for its effects on the human GI tract. The motilin receptor is expressed in enteric neurons of the human duodenum and colon. Development of motilin receptor agonists and antagonists may be useful in the treatment of multiple disorders of GI motility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feighner, S D -- Tan, C P -- McKee, K K -- Palyha, O C -- Hreniuk, D L -- Pong, S S -- Austin, C P -- Figueroa, D -- MacNeil, D -- Cascieri, M A -- Nargund, R -- Bakshi, R -- Abramovitz, M -- Stocco, R -- Kargman, S -- O'Neill, G -- Van Der Ploeg, L H -- Evans, J -- Patchett, A A -- Smith, R G -- Howard, A D -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Metabolic Disorders, Department of Medicinal Chemistry, Merck Research Laboratories, Building RY-80Y-265, 126 East Lincoln Avenue, Rahway, NJ 07065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381885" target="_blank"〉PubMed〈/a〉
