    Long-term neuropathological and neurochemical effects of nucleus basalis lesions in the rat (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-11-13
    Beschreibung: The long-term effects of excitotoxic lesions in the nucleus basalis magnocellularis of the rat were found to mimic several neuropathological and chemical changes associated with Alzheimer's disease. Neuritic plaque-like structures, neurofibrillary changes, and neuronal atrophy or loss were observed in the frontoparietal cortex, hippocampus, amygdala, and entorhinal cortex 14 months after the lesions were made. Cholinergic markers in neocortex were reduced, while catecholamine and indoleamine metabolism was largely unaffected at this time. Bilateral lesions of the nucleus basalis magnocellularis increased somatostatin and neuropeptide Y in the cortex of the rat by at least 138 and 284 percent, respectively, suggesting a functional interaction between cholinergic and peptidergic neurons that may differ from that in Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arendash, G W -- Millard, W J -- Dunn, A J -- Meyer, E M -- HD 17933/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 13;238(4829):952-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of South Florida, Tampa 33620.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2890210" target="_blank"〉PubMed〈/a〉

    The growth and composition of the U.S. labor force (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-09
    Beschreibung: In sharp contrast with the experiences of all other industrialized nations, the size of the labor force of the United States is growing rapidly while, simultaneously, its age, gender, and ethnic composition are changing markedly. Consequently, human resource issues present an unprecedented challenge in the nation's quest to achieve a fully employed and equitable society. New public policies that focus on labor market adjustment policies will be required if these developments are to be a boon rather than a bane to the emerging postindustrial economy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Briggs, V M Jr -- New York, N.Y. -- Science. 1987 Oct 9;238(4824):176-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉New York State School of Industrial and Labor Relations, Cornell University, Ithaca 14851.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3659908" target="_blank"〉PubMed〈/a〉

    Mapping the main immunogenic region and toxin-binding site of the nicotinic acetylcholine receptor (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-01-02
    Beschreibung: The alpha-chain of the nicotinic acetylcholine receptor carries the binding sites both for cholinergic ligands and for most experimentally induced or naturally occurring antibodies to the native receptor. By means of expression cloning in Escherichia coli, fusion proteins were derived from specific fragments of a complementary DNA encoding the mouse alpha-chain, allowing the mapping of the toxin-binding site to residues 160-216 and the main immunogenic region to residues 6-85. This approach permits the independent study of different functional domains of a complex receptor molecule and should be generally applicable to other proteins for which complementary DNA clones are available.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barkas, T -- Mauron, A -- Roth, B -- Alliod, C -- Tzartos, S J -- Ballivet, M -- New York, N.Y. -- Science. 1987 Jan 2;235(4784):77-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2432658" target="_blank"〉PubMed〈/a〉

    Corticotropin-releasing factor-producing neurons in the rat activated by interleukin-1 (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-10-23
    Beschreibung: Intraperitoneal administration of human recombinant interleukin-1 (IL-1) to rats can increase blood levels of corticosterone and adrenocorticotropic hormone (ACTH). The route by which IL-1 affects pituitary-adrenal activity is unknown. That the IL-1-induced pituitary-adrenal activation involves an increased secretion of corticotropin-releasing factor (CRF) is indicated by three lines of evidence. First, immunoneutralization of CRF markedly attenuated the IL-1-induced increase of ACTH blood levels. Second, after blockade of fast axonal transport in hypothalamic neurons by colchicine, IL-1 administration decreased the CRF immunostaining in the median eminence, indicating an enhanced release of CRF in response to IL-1. Third, IL-1 did not stimulate ACTH release from primary cultures of anterior pituitary cells. These data further support the notion of the existence of an immunoregulatory feedback circuit between the immune system and the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berkenbosch, F -- van Oers, J -- del Rey, A -- Tilders, F -- Besedovsky, H -- New York, N.Y. -- Science. 1987 Oct 23;238(4826):524-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Medical Faculty, Free University, Amsterdam, the Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2443979" target="_blank"〉PubMed〈/a〉

    A novel thyroid hormone receptor encoded by a cDNA clone from a human testis library (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-11-06
    Beschreibung: The c-erbA gene belongs to a multigene family that encodes transcriptional regulatory proteins including the v-erbA oncogene product, steroid hormone receptors, and the vitamin D3 receptor. A v-erbA DNA probe encoding the DNA-binding region of the v-erbA protein was used to screen a human complementary DNA testis library. One of the clones isolated, erbA-T-1, was found to encode a 490-amino acid protein (erbA-T). The erbA-T polypeptide shows high homology with the proteins encoded by both the chicken c-erbA and the human c-erbA-beta genes but is most closely related to the chicken gene. The chicken c-erbA and the human c-erbA-beta genes encode high-affinity receptors for thyroid hormone, and here it is shown that the erbA-T protein binds specifically to 3,5,3'-triiodo-L-thyronine with a dissociation constant of 3.8 +/- 0.2 x 10(-10) M. These data imply that more than one thyroid hormone receptor exists in humans and that these receptors might have different tissue- and gene-activating specificities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benbrook, D -- Pfahl, M -- DK-35083/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 6;238(4828):788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Research Center, La Jolla Cancer Research Foundation, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3672126" target="_blank"〉PubMed〈/a〉

    Electrical responses of eggs to acrosomal protein similar to those induced by sperm (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-03-27
    Beschreibung: The earliest known response of eggs to sperm in many species is a change in egg membrane potential. However, for no species is it known what components of the sperm cause the opening of the egg plasma membrane channels. Protein isolated from sperm acrosomal granules of the marine worm Urechis caused electrical responses in oocytes with the same form, amplitude, and ion dependence as the fertilization potentials induced by living sperm. Sperm initiated fertilization potentials in oocytes when sperm-oocyte fusion, but not binding, was inhibited by clamping oocyte membrane potentials to positive values. Acrosomal protein also initiated electrical responses in clamped oocytes. These results support the hypothesis that it is the sperm acrosomal protein that opens ion channels in the oocyte membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gould, M -- Stephano, J L -- New York, N.Y. -- Science. 1987 Mar 27;235(4796):1654-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3823908" target="_blank"〉PubMed〈/a〉
