    Thermal insulating capabilities of outdoor clothing materials (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-05
    Description: A single heat transfer measurement technique was used to determine the thermal insulating capabilities of four materials used in outdoor clothing-goose down, wool, polyester, and polyolefin. It was found that all provide very similar degrees of insulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaufman, W C -- Bothe, D -- Meyer, S D -- New York, N.Y. -- Science. 1982 Feb 5;215(4533):690-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17842404" target="_blank"〉PubMed〈/a〉

    Origin of the cholecystokinin-containing fibers in the rat caudatoputamen (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-01-08
    Description: Large Amounts of cholecystokinin-octapeptide (CCK) are present in the rat caudatoputamen. The peptide occurs in axons and nerve endings but not in perikarya. The origin of CCK in the caudatoputamen was investigated with the use of immunocytochemistry and a radioimmunoassay specific for CCK. Although a small amount of CCK (approximately 30 percent) originates in the amygdaloid complex, the bulk of the peptide (approximately 70 percent) occurs in processes of neurons located ventral to the caudatoputamen, that is, the claustrum or the piriform cortex. The claustrum and piriform cortex receive inputs from various cortical areas and the olfactory system, respectively, and may process information and relay it to the caudatoputamen. Thus CCK may by the transmitter in the final common pathway linking various cortical areas and the olfactory system to the caudatoputamen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, D K -- Beinfeld, M C -- Oertel, W H -- Brownstein, M J -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):187-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053570" target="_blank"〉PubMed〈/a〉

    High-affinity choline transport in proteoliposomes derived from rat cortical synaptosomes (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-27
    Description: Functional high- and low-affinity choline transport processes from rat cortical plasma membranes were reconstituted in phosphatidylcholine bilayer liposomes. The high-affinity choline transporter demonstrated a pharmacological profile and ion dependency that were identical to those of intact synaptosomes. This preparation may be used to further characterize choline transport and, with appropriate supplementation, to investigate the release of acetylcholine in the absence of synaptic vesicles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, E M -- Cooper, J R -- NS 09836/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):843-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100928" target="_blank"〉PubMed〈/a〉

    Androgens alter the tuning of electroreceptors (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-13
    Description: Weakly electric fish possess electroreceptors that are tuned to their individual electric organ discharge frequencies. One genus, Sternopygus, displays both ontogenetic and seasonal shifts in these frequencies, possibly because of endocrine influences. Systemic treatment with androgens lowers the discharge frequencies in these animals. Concomitant with these changes in electric organ discharge frequencies are decreases in electroreceptor best frequencies; hence the close match between discharge frequency and receptor tuning is maintained. These findings indicate that the tuning of electroreceptors is dynamic and that it parallels natural shifts in electric organ discharge frequency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, J H -- Zakon, H H -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):635-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17817533" target="_blank"〉PubMed〈/a〉

    Tetrodotoxin blocks the formation of ocular dominance columns in goldfish (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-05
    Description: Optic fibers from both eyes were made to regenerate simultaneously into one tectum in goldfish. Autoradiography at various times later revealed that regenerating left and right fibers overlapped extensively for up to 4 weeks and subsequently segregated into eye dominance columns by 8 weeks. Continuous tetrodotoxin treatment of both eyes prevented the formation of columns for up to 13 weeks and was equally effective if begun at 6 weeks. When tetrodotoxin treatment was stopped after 11 weeks, columns subsequently formed in the next 3 weeks. Blockade of only one eye did prevent column formation at 8 weeks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, R L -- NS15381/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):589-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123262" target="_blank"〉PubMed〈/a〉

    Virus-induced corticosterone in hypophysectomized mice: a possible lymphoid adrenal axis (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Infection of hypophysectomized mice with Newcastle disease virus caused a time-dependent increase in corticosterone and interferon production. Prior treatment with dexamethasone completely inhibited the virus-induced elevation in corticosterone concentration, but did not significantly alter the interferon response. Lymphocytes appear to be the most likely source of an adrenocorticotropin-like substance that is responsible for the increased corticosterone, since spleen cells from the virus-infected, but not from control or dexamethasone-treated, hypophysectomized mice showed positive immunofluorescence with antibody to adrenocorticotropin-(1-13 amide). Thus the adrenocorticotropin-like material and interferon appear to be coordinately induced the differentially controlled products of different genes. These findings strongly suggest the existence of a lymphoid-adrenal axis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, E M -- Meyer, W J -- Blalock, J E -- AM30046/AM/NIADDK NIH HHS/ -- HL20201/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1311-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6183748" target="_blank"〉PubMed〈/a〉

    Small nuclear RNA U2 is base-paired to heterogeneous nuclear RNA (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-30
    Description: Eukaryotic cells contain a set of low molecular weight nuclear RNA's. One of the more abundant of these is termed U2 RNA. The possibility that U2 RNA is hydrogen-bonded to complementary sequences in other nuclear RNA's was investigated. Cultured human (HeLa) cells were treated with a psoralen derivative that cross-links RNA chains that are base-paired with one another. High molecular weight heterogeneous nuclear RNA was isolated under denaturing conditions, and the psoralen cross-links were reversed. Electrophoresis of the released RNA and hybridization with a human cloned U2 DNA probe revealed that U2 is hydrogen-bonded to complementary sequences in heterogeneous nuclear RNA in vivo. In contrast, U2 RNA is not base-paired with nucleolar RNA, which contains the precursors of ribosomal RNA. The results suggest that U2 RNA participates in messenger RNA processing in the nucleus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calvet, J P -- Meyer, L M -- Pederson, T -- GM 21595/GM/NIGMS NIH HHS/ -- GM 27265/GM/NIGMS NIH HHS/ -- P30 12708/PHS HHS/ -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):456-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178162" target="_blank"〉PubMed〈/a〉
