    Maternal care, hippocampal glucocorticoid receptors, and hypothalamic-pituitary-adrenal responses to stress (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-09-12
    Description: Variations in maternal care affect the development of individual differences in neuroendocrine responses to stress in rats. As adults, the offspring of mothers that exhibited more licking and grooming of pups during the first 10 days of life showed reduced plasma adrenocorticotropic hormone and corticosterone responses to acute stress, increased hippocampal glucocorticoid receptor messenger RNA expression, enhanced glucocorticoid feedback sensitivity, and decreased levels of hypothalamic corticotropin-releasing hormone messenger RNA. Each measure was significantly correlated with the frequency of maternal licking and grooming (all r's 〉 -0.6). These findings suggest that maternal behavior serves to "program" hypothalamic-pituitary-adrenal responses to stress in the offspring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, D -- Diorio, J -- Tannenbaum, B -- Caldji, C -- Francis, D -- Freedman, A -- Sharma, S -- Pearson, D -- Plotsky, P M -- Meaney, M J -- New York, N.Y. -- Science. 1997 Sep 12;277(5332):1659-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Neuroendocrinology Laboratory, Douglas Hospital Research Center, McGill University, Montreal, Canada H4H 1R3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9287218" target="_blank"〉PubMed〈/a〉

    Phenylalanine depletion for the management of phenylketonuria: use of enzyme reactors with immobilized enzymes (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-09-01
    Description: Multitubular enzyme reactors with immobilized phenylalanine ammonia lyase were tested in vitro and in vivo for depletion of phenylalanine in circulating blood. Sustained reduction of phenylalanine was achieved in less than 30 minutes. A 50% decrease of phenylalanine was obtained with a 2-hour application of enzyme reactors and was maintained for more than 2 days. Similar enzyme reactors have therapeutic potential for temporary management of phenylketonuric patients when their circulating phenylalanine becomes exceedingly high because of infection, fever, or pregnancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ambrus, C M -- Ambrus, J L -- Horvath, C -- Pedersen, H -- Sharma, S -- Kant, C -- Mirand, E -- Guthrie, R -- Paul, T -- New York, N.Y. -- Science. 1978 Sep 1;201(4358):837-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/567372" target="_blank"〉PubMed〈/a〉

    Diversity of circumsporozoite antigen genes from two strains of the malarial parasite Plasmodium knowlesi (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-08-23
    Description: The complete nucleotide sequence of the coding region of the circumsporozoite antigen gene (CS gene) of the Nuri strain of the malarial parasite Plasmodium knowlesi is presented. The gene from the Nuri strain exhibits a novel form of sequence diversity when compared to the CS gene from the H strain. Instead of the 12 tandem repeating 36-base pair units of the H strain, the Nuri strain contains 16 tandem repeating 27-base pair units of a different nucleotide sequence that encodes a different repeating peptide. In contrast, the 5' and 3' coding and noncoding sequences flanking the repeats are 98 percent conserved in both strains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sharma, S -- Svec, P -- Mitchell, G H -- Godson, G N -- 1 R01 AI21496-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 23;229(4715):779-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/4023712" target="_blank"〉PubMed〈/a〉

    Expression of the major surface antigen of Plasmodium knowlesi sporozoites in yeast (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-17
    Description: The circumsporozite protein, a surface antigen of the sporozoite stage of the monkey malarial parasite Plasmodium knowlesi, was expressed in the yeast Saccharomyces cerevisiae by using an expression vector containing the 5' regulatory region of the yeast alcohol dehydrogenase I gene. It was necessary to eliminate the entire 5' upstream region of the parasite DNA to obtain the expression of this protein. Only the circumsporozoite precursor was produced by the yeast transformants, as detected by immunoblotting. About 55 and 20 percent of the circumsporozoite protein produced in yeast was associated wtih the 25,000 g and 150,000 g particulate fractions, respectively. The protein could be solubilized in Triton X-100 and was stable in solubilized extracts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sharma, S -- Godson, G N -- 1 R01 AI21496-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1985 May 17;228(4701):879-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3890178" target="_blank"〉PubMed〈/a〉

    Selection rules for cavity-enhanced Brillouin light scattering from magnetostatic modes (2018)
    American Physical Society (APS)
    Details
    Publication Date: 2018-06-21
    Description: Author(s): J. A. Haigh, N. J. Lambert, S. Sharma, Y. M. Blanter, G. E. W. Bauer, and A. J. Ramsay Brillouin light scattering (BLS) is a useful tool for studying magnons, the elementary excitations of magnetic order. However, this process is typically quite weak. In order to enhance BLS, optical cavity modes, such as the whispering gallery modes in a sphere of transparent magnetic material, can be exploited. Here, the authors study cavity-enhanced BLS from magnons in a range of different magnetostatic modes. The selection rules that govern the process are identified and understood based on recent theoretical predictions (Phys. Rev. B 96, 094412 (2017)). Additional enhancement of BLS can be achieved through the better spatial overlap of higher-order magnetic modes with the optical modes. [Phys. Rev. B 97, 214423] Published Wed Jun 20, 2018

    Drag coefficient and velocity of rise of a single collasping two-phase bubble (1997)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 43 (1997), S. 1955-1963

    Notes: The velocity of rise and the drag of a single vapor bubble collapsing in another immiscible liquid were measured experimentally. During the process of collapse, the dispersed-phase vapor bubble was transformed to a two-phase bubble with condensate accumulating at the rear of the two-phase bubble and vapor at its top. Such a configuration of a two-phse bubble is commonly known as a drobble. Experimental data for the six pairs of liquids covered a range of drobble (two-phase bubble) Reynolds numbers from 0.003 to 3,000. Two regimes of drobble movement were encountered. In the first regime (Re 〈 100), the drobble maintained its sphericity, and the observed drag was less than the solid-sphere drag predicted by the established solid sphere or Hadamard et al. fluid-sphere drag models. In the second regime, the drobble was deformed and oscillated; the observed drag departed suddenly from predictions of spherical models and increased with increasing Reynolds numbers. The critical Reynolds number covered a range from 100 to 1,000. Empirical models for drobble velocity and drag coefficient are derived.
