    Human sleep: its duration and organization depend on its circadian phase (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-12-12
    Description: Two- to threefold variations in sleep length were observed in 12 subjects living on self-selected schedules in an environment free of time cues. The duration of polygraphically recorded sleep episodes was highly correlated with the circadian phase of the body temperature rhythm at bedtime and not with the length of prior wakefulness. Furthermore, the rate of REM (rapid eye movement) sleep accumulation , REM latency, bedtime selection, and self-rated alertness assessments were also correlated with the body temperature rhythm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Czeisler, C A -- Weitzman, E d -- Moore-Ede, M C -- Zimmerman, J C -- Knauer, R S -- AG-00792/AG/NIA NIH HHS/ -- GM-07365/GM/NIGMS NIH HHS/ -- MH-28460/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 12;210(4475):1264-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434029" target="_blank"〉PubMed〈/a〉

    Amino acid acylation: a mechanism of nitrogen excretion in inborn errors of urea synthesis (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-08
    Description: Treatment of a patient deficient in carbamyl phosphate synthetase with benzoate or phenylacetic acid resulted in an increase in urinary nitrogen, which could be accounted for by the respective amino acid acylation product, hippurate or phenylacetylgultamine. Benzoate treatment of four hyperammonemic comatose patients led to clinical improvement and a return of plasma ammonium levels toward normal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brusilow, S -- Tinker, J -- Batshaw, M L -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243418" target="_blank"〉PubMed〈/a〉

    Reorganization of the axon membrane in demyelinated peripheral nerve fibers: morphological evidence (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-07
    Description: Cytochemical staining of demyelinated peripheral axons revealed two types of axon membrane organization, one of which suggests that the demyelinated axolemma acquires a high density of sodium channels. Ferric ion-ferrocyanide stain was confined to a restricted region of axon membrane at the beginning of a demyelinated segment or was distributed throughout the demyelinated segment of axon. The latter pattern represents one possible morphological correlate of continuous conduction through a demyelinated segment and suggests a reorganization of the axolemma after demyelination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Foster, R E -- Whalen, C C -- Waxman, S G -- NS-15320/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):661-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6159685" target="_blank"〉PubMed〈/a〉

    Single-nutrient microbial competition: qualitative agreement between experimental and theoretically forecast outcomes (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-28
    Description: When microbial strains compete for the same limiting nutrient in continuous culture, resource-based competition theory predicts that only one strain will survive and all others will die out. The surviving strain expected from theory will be the one with the smallest subsistence or "break-even" concentration of the limiting resource, a concentration defined by the J parameter. This prediction has been confirmed in the case of auxotrophic bacterial strains competing for limiting tryptophan. Because the value of J can be measured on the strains grown alone, the theory can predict the qualitative outcomes of mixed-growth competition in advance of actual competition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hansen, S R -- Hubbell, S P -- New York, N.Y. -- Science. 1980 Mar 28;207(4438):1491-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6767274" target="_blank"〉PubMed〈/a〉

    Antibodies to cerebroside sulfate inhibit the effects of morphine and beta-endorphin (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-01-04
    Description: Morphine and beta-endorphin inhibit the shaking response of pentobarbital-anesthetized rats to ice water. Stereotaxically guided administration of antibodies to cerebroside sulfate into the periaqueductal gray region, the most sensitive brain region in which to demonstrate inhibition of this response, antagonizes the effect of morphine and beta-endorphin. These results suggest that cerebroside sulfate may be an integral component of an opiate receptor in rat brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Craves, F B -- Zalc, B -- Leybin, L -- Baumann, N -- Loh, H H -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):75-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243189" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-05-09
    Description: Olfactory sensitivity to acetic acid, isobutyric acid, and 2-sec-butyl-cyclohexanone was tested in 97 adult male twin pairs to determine the extent to which variation in odor perception was genetically determined. Analysis of the data revealed no evidence for heritability of olfactory sensitivity. However, factors significantly associated with odor perception included cigar, pipe, and cigarette smoking; body fatness; alcohol consumption; and diabetes mellitus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hubert, H B -- Fabsitz, R R -- Feinleib, M -- Brown, K S -- New York, N.Y. -- Science. 1980 May 9;208(4444):607-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7189296" target="_blank"〉PubMed〈/a〉

    Excitatory and inhibitory effects of opiates in the rat vas deferens: a dual mechanism of opiate action (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-03
    Description: Both natural (-)-morphine and its unnatural enantiomer (+)-morphine exert an excitatory action on electrically stimulated contractions of rat vas deferens. Preexposure to (-)-morphine results in cross-tolerance to the inhibitory action of beta-endorphin. (-)-Naloxone and its stereoisomer (+)-naloxone also exert an excitatory action, but only (-)-naloxone bocks the inhibtory action of beta-endorphin. Thus morphine exerts a dual action on a peripheral organ: one an inhibitory action mediated by the stereospecific endorphin receptor that is blocked stereospecifically by naloxone, the other an excitatory action mediated by a nonstereospecific receptor that is not blocked by naloxone. The opiate abstinence syndrome is seen as due to the unmasking of the excitatory action of opiates when its concomitant inhibitory influence is removed by selective blockade by naloxone or weakened by selective tolerance. The view that the rat vas deferens is devoid of morphine receptors is now seen as arising from a reverse example of morphine's dual action: the masking of the inhibitory action of morphine by its concomitant and more potent excitatory action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacquet, Y F -- DA 00367/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 3;210(4465):95-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6158098" target="_blank"〉PubMed〈/a〉

    Allele increasing susceptibility to human breast cancer may be linked to the glutamate-pyruvate transaminase locus (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-25
    Description: The patterns of the occurrence of breast cancer in 11 high-risk families were evaluated by segregation and linkage analysis. These patterns were consistent with the hypothesis that increased susceptibility to breast cancer was inherited as an autosomal dominant allele with high penetrance in women. The postulated susceptibility allele in these families may be chromosomally linked to the glutamate-pyruvate transaminase (E.C. 2.6.1.2, alanine aminotransferase) locus. Confirmation of this linkage in other families would establish the existence of a gene increasing susceptibility to breast cancer. Since there is no association in the general population between a woman's glutamate-pyruvate transaminase genotype and her cancer risk, the glutamate-pyruvate transaminase linkage cannot be used as a screening test for breast cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, M C -- Go, R C -- Elston, R C -- Lynch, H T -- Petrakis, N L -- New York, N.Y. -- Science. 1980 Apr 25;208(4442):406-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367867" target="_blank"〉PubMed〈/a〉

    Testosterone-mediated sexual dimorphism of mitochondria and lysosomes in mouse kidney proximal tubules (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-29
    Description: In kidney proximal tubules of male mice the mitochondria are larger and more electron-lucent, autophagic vacuoles and lysosomes (predominantly myeloid bodies) more numerous and voluminous, and exocytosed intraluminal myeloid bodies more common than in females. Males also have higher kidney activities of mitochondrial cytochrome c oxidase and lysosomal hydrolases, and excrete larger quantities of hydrolases and protein in the urine. Orchiectomy evokes the feminine pattern whereas testosterone administration induces the male pattern. Endogenous testosterone modulates mitochondrial structure and function and enhances the activity of the lysosomal-vacuolar system in proximal tubule cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koenig, H -- Goldstone, A -- Blume, G -- Lu, C Y -- New York, N.Y. -- Science. 1980 Aug 29;209(4460):1023-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403864" target="_blank"〉PubMed〈/a〉

    Liver tumors induced in rats by oral administration of the antihistaminic methapyrilene hydrochloride (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-15
    Description: The antihistaminic over-the-counter drug methapyrilene hydrochloride, mixed with food at a concentration of 0.1 percent, was administered to 50 male and 50 female Fischer rats. A second group of 50 male and 50 female rats was given the same treatment together with 0.2 percent of sodium nitrite added to the food. Almost all of the rats in both groups developed liver neoplasms, mainly hepatocellular carcinomas and cholangiocarcinomas. The first rat died with a liver neoplasm at the 43rd week. Over 50 percent of the rats in both groups had metastases from the carcinomas of the liver to distant organs. Control rats treated with nitrite only, or untreated, did not develop liver neoplasms. There was no discernible effect of nitrite on the carcinogenicity of methapyrilene hydrochloride.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lijinsky, W -- Reuber, M D -- Blackwell, B N -- New York, N.Y. -- Science. 1980 Aug 15;209(4458):817-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403848" target="_blank"〉PubMed〈/a〉

    Sexual dimorphism in extent of axonal sprouting in rat hippocampus (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-13
    Description: Sympathetic axons, normally innervating the extracerebral vasculature, sprout into denervated regions of the hippocampal formation after lesions of the medial septal nucleus or fimbria in adult female rats. Similar lesions in adult males also elicit the sympathetic ingrowth; however, the number of anomalous axons is greatly reduced and their distribution is altered. In adult males the sympathetic axons do not send out collaterals within the stratum oriens of region CA3 or the molecular layer or deep hilar regions of the area dentata, as they do in adult females. Lesions in juveniles of both sexes result in more vigorous sprouting than in their adult counterparts. In the young males the anomalous axons are distributed more extensively into the dentate molecular layer; in the young females the axons merely send out more collaterals within the same regions as in the adults. This sexually dimorphic response to central nervous system damage suggests either that the sprouting is affected by the hormonal environment of the mature hippocampal system or that this brain region, like the hypothalamus, may express permanent morphological or physiological differences as a result of exposure to sex steroids during development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loy, R -- Milner, T A -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1282-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375941" target="_blank"〉PubMed〈/a〉

    Immunoglobulin gene rearrangement in immature B cells (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Two types of immature B cells, namely fetal liver hybridomas and the leukemic cell line 70Z/3, both of which have cytoplasmic mu chains but no light chains, were examined for DNA rearrangements of their light chain and heavy chain immunoglobulin genes. In the fetal liver hybridomas, which were constructed from fetal liver cells and a tumor cell, no light chain gene rearrangement was observed, whereas in the 70Z/3 cell line a kappa light chain rearrangement probably occurred. The results suggest that, although the lack of light chain synthesis can be due to a lack of gene rearrangement, there may also be transcriptional regulation, which may also be important for the expression of light chain immunoglobulins in immature B cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maki, R -- Kearney, J -- Paige, C -- Tonegawa, S -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1366-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6774416" target="_blank"〉PubMed〈/a〉

    Description: Autoradiographic and biochemical analyses of the hearts of female rhesus monkeys and baboons indicate that atrial and ventricular myocardial cells contain androgen receptors. Although the specific effects of nuclear uptake and retention of androgen on the function of heart muscle cells are not known, the presence of this receptor suggests that sex steroid hormones may affect myocardial function directly and may explain some of the peculiar differences in heart disease between men and women.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGill, H C Jr -- Anselmo, V C -- Buchanan, J M -- Sheridan, P J -- New York, N.Y. -- Science. 1980 Feb 15;207(4432):775-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766222" target="_blank"〉PubMed〈/a〉

    Mediation of diurnal fluctuations in pain sensitivity in the rat by food intake patterns: reversal by naloxone (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-10
    Description: Rats maintained on a 12-hour light-dark cycle were tested for pain sensitivity after being deprived of food during either the dark or the light phase of the cycle. Diurnal fluctuations in pain sensitivity were observed. The fluctuations followed food intake patterns rather than a natural circadian rhythm, with food deprivation producing a decrease in pain sensitivity. The analgesic response produced by this mild food deprivation was strongly attenuated by naloxone or feeding, suggesting that endogenous opioid systems may be related to patterns of food intake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGivern, R F -- Berntson, G G -- New York, N.Y. -- Science. 1980 Oct 10;210(4466):210-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7191143" target="_blank"〉PubMed〈/a〉

    Vomeronasal pump: significance for male hamster sexual behavior (1980)

    Details
    Publication Date: 1980-03-14
    Description: Vomeronasal chemoreceptors segregated within the vomeronasal organ are important for male hamster sexual behavior. An autonomically controlled vascular pump, previously demonstrated in anesthetized animals, can transport stimuli to the receptors. Interruption of the efferent nerves controlling the pump results in behavioral deficits similar to those produced by interruption of the afferent nerves carrying information from the vomeronasal organ to the brain. Pump activation is thus a prerequisite for normal vomeronasal stimulation in behaving animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meredith, M -- Marques, D M -- O'Connell, R O -- Stern, F L -- New York, N.Y. -- Science. 1980 Mar 14;207(4436):1224-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355286" target="_blank"〉PubMed〈/a〉

    Osmolality and potassium ion: their roles in initiation of sperm motility in teleosts (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-12-05
    Description: Spermatozoa that are quiescent in electrolyte and nonelectrolyte solutions isotonic to seminal plasma show motility when the semen is diluted with hypotonic solution in freshwater teleosts (four species tested) and with hypertonic solution in marine teleosts (five species tested). Decrease or increase, respectively, in osmolality of the environment may be the factor initiating sperm motility in these species. The motility of chum salmon spermatozoa in a sodium chloride solution isotonic to seminal plasma is completely suppressed by approximately 10 millimoles of potassium per kilogram; topminnow spermatozoa, however, were immotile in a nonelectrolyte solution, and motility was induced by electrolytes, especially potassium. Thus ions, rather than osmolality, may be an essential determinant of sperm motility in salmonid and viviparous teleosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morisawa, M -- Suzuki, K -- New York, N.Y. -- Science. 1980 Dec 5;210(4474):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444445" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-09-12
    Description: The interaction of endogenous opiates and stress-induced eating in rats was evaluated by pharmacological manipulation. Eating induced by the tail-pinch method was inhibited by the opitate antagonist naloxone; after being repeatedly stressed over a 10-day period and then given nalozone, the rats behaved in a manner indistinguishable from the "wet-dog" shakes of opiate withdrawal. Thus endogenous opiates may have a role in the control of stress-related eating, a finding that may have therapeutic implications for humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morley, J E -- Levine, A S -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1259-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6250222" target="_blank"〉PubMed〈/a〉

    Description: High mortality rate in rats with large medial preoptic lesions discourage their use in studies of brain function. However, virtually all such animals (six out of seven) survived indefinitely if kept at an ambient temperature of 15 degrees C for 2 hours before and 10 to 12 hours after the lesions were made. Although these rats appeared otherwise healthy, they could not maintain normal both temperatures in short-term cold tests. In contrast, five of the nine rats kept at 25 degrees C died within 10 hours after the operation, and three more died within 5 days. Rats kept at 25 degrees C had a much higher incidence of cardiac arrhythmias than did rats kept at 15 degrees C, which may be responsible for their higher moratlity rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagel, J A -- Satinoff, E -- New York, N.Y. -- Science. 1980 Apr 18;208(4441):301-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367860" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-01-04
    Description: The activity of cyanide-sensitive, Cu-Zn superoxide dismutase (SOD) was studied in liver sytosols from H-2 congenic strains of mice. Higher SOD activity was found in livers of mice having H-2b/A.BY, B10, and C3H.SW/haplotypes than in those of H-2a, H-2k and H-2d haplotypes. Segregation studies supported these correlations. In H-2 recombinant strains of mice, the genes influencing the liver SOD activity occur, as ascertained by mapping techniques, at or near the H-2d region of the major histocompatibility complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Novak, R -- Bosze, Z -- Matkovics, B -- Fachet, J -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):86-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7350646" target="_blank"〉PubMed〈/a〉

    Calcium regulation during stimulus-secretion coupling: continuous measurement of intracellular calcium activities (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-25
    Description: Accurate measurements of intracellular calcium activities in salivary gland epithelial cells of the insect Phormia regina were obtained with microelectrodes in which N,N'-di(11-ethoxycarbonyl)undecyl-N,N'-4,5-tetramethyl-3,6-dioxaoctane diacid diamide wsa incorporated in a liquid membrane system. When calibrated in solutions approximating the ionic concentration of the cell interior, these microelectrodes gave rapid stable responses that were linear functions of the logarithm of calcium activities and were not affected by potassium, sodium and magnesium. Continuous monitoring of calcium activities during serotonin-induced saliva release provided direct evidence of hormonal influence on transmembrane calcium movement and spontaneous regulation of intracellular calcium by stimulated cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Doherty, J -- Youmans, S J -- Armstrong, W M -- Stark, R J -- New York, N.Y. -- Science. 1980 Jul 25;209(4455):510-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7394518" target="_blank"〉PubMed〈/a〉

    Kindling induces long-lasting alterations in response of hippocampal neurons to elevated potassium levels in vitro (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-13
    Description: The cellular basis of kindling was studied electrophysiologically with slices of guinea pig hippocampus. Normally, epileptiform activity can be induced in the slices only by combined exposure to elevated potassium levels and a chemical convulsant such as penicillin. In hippocampal slices from pentylenetetrazole-kindled animals, however, elevated potassium alone can induce seizures. These data suggest that kindling elicits long-term changes in neuronal excitability that may involve ionic mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oliver, A P -- Hoffer, B J -- Wyatt, R J -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1264-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375936" target="_blank"〉PubMed〈/a〉

    Altering genotype and phenotype by DNA-mediated gene transfer (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Transformation, or DNA-mediated gene transfer, permits the introduction of new genetic information into a cell and frequently results in a change in phenotype. The transforming DNA is ultimately integrated into a recipient cell chromosome. No unique chromosomal locations are apparent, different lines contain the transforming DNA on different chromosomes. Expression of transformed genes frequently results in the synthesis of new polypeptide products which restore appropriate mutant cells to the wild-type phenotype. Thus transformation provides an in vivo assay for the functional role of DNA sequence organization about specific genes. Transforming genes coding for selectable functions, such as adenine phosphoribosyltransferase or thymidine kinase, have now been isolated by utilizing transformation in concert with molecular cloning. Finally, transformation may provide a general approach to the analysis of complex heritable phenotypes by permitting the distinction between phenotypic changes without concomitant changes in DNA and functional genetic rearrangements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pellicer, A -- Robins, D -- Wold, B -- Sweet, R -- Jackson, J -- Lowy, I -- Roberts, J M -- Sim, G K -- Silverstein, S -- Axel, R -- CA 16346/CA/NCI NIH HHS/ -- CA 17477/CA/NCI NIH HHS/ -- CA 23767/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1414-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7414320" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-05-09
    Description: The transitional epithelium of the urinary bladder secretes and binds to its surface a glycosaminoglycan than inhibits the adherence of bacteria. Synthetic sulfonated glycosaminoglycans instilled intraluminally into bladders whose natural mucin layer has been removed are as effective as the natural mucin in preventing bacterial adherence. It also appears that adherence of calcium and protein is reduced in the presence of both the natural mucin layer and the synthetic sulfonated glycosaminoglycan sodium pentosanpolysulfate, suggesting that the antiadherence activity of both natural and synthetic surface glycosaminoglycans in the bladder extends to the molecular and ionic levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, C L -- Stauffer, C -- Schmidt, J D -- New York, N.Y. -- Science. 1980 May 9;208(4444):605-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6154316" target="_blank"〉PubMed〈/a〉

    Sperm-egg interaction: evidence for boar sperm plasma membrane receptors for porcine zona pellucida (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-01-04
    Description: Freshly ejaculated, noncapacitated boar sperm bind rapidly and in large numbers to pig egg zona pellucida in vitro. In the present study, the number of sperm bound decreased sharply when sperm motility was lowered by energy poisons or by reducing the temperature. Highly motile sperm from humans, guinea pigs, and rats, added at concentrations ten times higher than control sperm, did not bind to the porcine zona. At the same high concentration, a small number of hamster and bull sperm bound to the zona. Binding of boar sperm to the zona pellucida was blocked almost completely by diluted whole antiserum to sperm plasma membranes and by univalent (Fab) antibody to these membranes. When antibody to sperm plasma membrane was first absorbed with plasma membrane vesicles, sperm binding was not inhibited. These results provide direct evidence for the existence of sperm plasma membrane receptors for the zona pellucida of the pig.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peterson, R N -- Russell, L -- Bundman, D -- Freund, M -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):73-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7188647" target="_blank"〉PubMed〈/a〉

    Description: Fat cells or fat cell membranes were briefly subjected to mild proteolysis under conditions where insulin receptors were either free or bound to (125)I-labeled insulin. When receptors were then affinity-labeled to visualize the effects of this treatment, it was observed that receptors that had been occupied by ligand during proteolysis exhibited greater rates of degradation than unoccupied receptors. These results demonstrate that insulin-receptor interaction induces a change in receptor structure that may be related to signal transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pilch, P F -- Czech, M P -- AM 06069/AM/NIADDK NIH HHS/ -- AM 17893/AM/NIADDK NIH HHS/ -- HD 11343/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1980 Dec 5;210(4474):1152-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7003712" target="_blank"〉PubMed〈/a〉

    Description: The expression of human esterase D was evaluated quantitatively and qualitatively in five persons with partial deletions or duplications of chromosome 13. The results showed that the locus of this enzyme is at band 13q14. Deletion of this same band in other subjects has been found previously to indicate a predisposition to the development of retinoblastoma, which was present in the four individuals in this study who had partial deletions of chromosome 13. Because of this close synteny, esterase D evaluation should aid in the diagnosis and genetic counseling of retinoblastoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sparkes, R S -- Sparkes, M C -- Wilson, M G -- Towner, J W -- Benedict, W -- Murphree, A L -- Yunis, J J -- New York, N.Y. -- Science. 1980 May 30;208(4447):1042-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375916" target="_blank"〉PubMed〈/a〉

    Directed deletion of a yeast transfer RNA intervening sequence (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Many eukaryotic genes contain intevening sequences, segments of DNA that interrupt the continuity of the gene. They are removed from RNA transcripts of the gene by a process known as splicing. The intervening sequence in a yeast tyrosine transfer RNA (tRNA Tyr) suppressor gene was deleted in order to test its role in the expression of the gene. The altered gene and its parent were introduced into yeast by transformation. Both genes exhibited suppressor function, showing that the intervening sequence is not absolutely essential for the expression of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallace, R B -- Johnson, P F -- Tanaka, S -- Schold, M -- Itakura, K -- Abelson, J -- CA10984/CA/NCI NIH HHS/ -- GM 26391/GM/NIGMS NIH HHS/ -- GM 35658/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1396-400.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6997991" target="_blank"〉PubMed〈/a〉

    Methylphenidate and hyperactivity: effects on teacher behaviors (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-13
    Description: Teacher interactions with hyperactive and comparison boys were observed during classroom activities. A double-blind, methylphenidate-placebo cross-over design was used within the hyperactive group. With no knowledge of any child's diagnosis or drug status, the teacher was more intense and controlling toward hyperactive boys taking placebo than toward either medicated hyperactive boys or comparison boys; her behavior did not differ toward the latter two groups. Discussion focused on the need to consider the broad social ramifications of pharmacologic treatment programs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whalen, C K -- Henker, B -- Dotemoto, S -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1280-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375940" target="_blank"〉PubMed〈/a〉

    Pituitary gonadotropin-releasing hormone receptors during the rat estrous cycle (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-22
    Description: The binding of [6-alanine]gonadotropin-releasing hormone to pituitary plasma membranes increased threefold between metestrus and early proestrus in female rats. Receptor numbers fell rapidly on the afternoon of proestrus coincident with the preovulatory gonadotropin surge. The numbers of receptors for gonadotropin-releasing hormone were positively correlated with concentrations of estradiol in serum; this pattern may be a necessary component of increased pituitary sensitivty to gonadotropin-releasing hormone observed during proestrus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Savoy-Moore, R T -- Schwartz, N B -- Duncan, J A -- Marshall, J C -- New York, N.Y. -- Science. 1980 Aug 22;209(4459):942-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6250218" target="_blank"〉PubMed〈/a〉

    Glucan-induced modification of murine viral hepatitis (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-04
    Description: Glucan, a macrophage stimulant, was evaluated for its ability to alter survival and phagocytic dysfunction in mice challenged with mouse hepatitis virus strain MHV-A59. Administration of glucan before the mice were challenged with the virus significantly prolonged median survival time but did not modify overall mortality compared with control mice given dextrose. Maximal effectiveness was achieved when glucan was administered both before and after the viral challenge. In contrast to the marked hepatic parenchymal cell necrosis observed in the control mice, glucan-treated mice exhibited reduced pathology. Intraperitoneal administration of MHV-A59 resulted in a significant depression of phagocytic activity compared with controls that were not exposed to the virus. The enhancement in phagocytic function in glucan-treated control mice was unaltered in virus-challenged, glucan-treated mice. Thus glucan is capable of increasing survival, inhibiting hepatic necrosis, and maintaining an activated state of phagocytic activity in mice challenged with MHV-A59. Macrophage stimulants may have a significant role in the modification of virally induced hepatic lesions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, D L -- Di Luzio, N R -- New York, N.Y. -- Science. 1980 Apr 4;208(4439):67-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7361108" target="_blank"〉PubMed〈/a〉

    Multiple daily amphetamine administration: behavioral and neurochemical alterations (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-15
    Description: In rats, multiple daily amphetamine injections (2.5 milligrams per kilogram of body weight, injected subcutaneously every 4 hours for 5 days) resulted in a progressive augmentation in response, characterized by a more rapid onset and an increased magnitude of stereotypy. By contrast, offset times of both the stereotypy and the poststereotypy hyperactivity periods were markedly shortened. When the animals were retested with the same dose of amphetamine 8 days after the long-term treatment was discontinued, the time of offset of the stereotypy and hyperactivity phases had recovered to values found with short-term amphetamine treatment, whereas the more rapid onset of stereotypy persisted. Brain monoamine and amphetamine concentrations and tyrosine hydroxylase activity were determined in comparably treated rats at times corresponding to the behavioral observations. The behavioral data indicate that enhanced responsiveness to amphetamine following its repeated administration may contribute to the development of amphetamine psychosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Segal, D S -- Weinberger, S B -- Cahill, J -- McCunney, S J -- New York, N.Y. -- Science. 1980 Feb 15;207(4433):905-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7188815" target="_blank"〉PubMed〈/a〉

    Compensatory increase in tyrosine hydroxylase activity in rat brain after intraventricular injections of 6-hydroxydopamine (1980)

    Publication Date: 1980-02-01
    Description: The neurotoxin 6-hydroxydopamine produced a permanent loss of endogenous norepinephrine and of 3H-labeled norepinephrine uptake sites in the hippocampus within 5 days. These losses were initially accompanied by parallel decreases in tyrosine hydroxylase activity and synaptosomal norepinephrine synthesis. Within 21 days, however, hippocampal tyrosine hydroxylase activity and norepinephrine synthesis rate increased three- to fivefold. These data suggest a novel form of plasticity in brain-damaged animals characterized by an increase in the capacity for transmitter biosynthesis in residual neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Acheson, A L -- Zigmond, M J -- Stricker, E M -- New York, N.Y. -- Science. 1980 Feb 1;207(4430):537-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6101509" target="_blank"〉PubMed〈/a〉

    Microwaves induce peripheral vasodilation squirrel monkeys (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-21
    Description: Vasomotor activity in cutaneous tail veins was indexed by changes in local skin temperature during exposure of the whole body to 12.3-centimeter continuous microwaves. At an ambient temperature (26 degrees C) just below that at which tail vessels normally vasodilate, criterion dilation was initiated by 5-minute exposures to a microwave power density of 8 milliwatts per square centimeter. This intensity deposits energy equivalent to approximately 20 percent of the monkey's resting metabolic rate but produces no observable change in deep body temperature. Intensity increments of 3 to 4 milliwatts per square centimeter for 1 degree C reductions in ambient temperature below 26 degrees C produced identical responses. That no vasodilation occurred during infrared exposures of equivalent power density suggests that noncutaneous thermosensitive structures may mediate microwave activation of thermoregulatory responses in the peripheral vasomotor system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adair, E R -- Adams, B W -- New York, N.Y. -- Science. 1980 Mar 21;207(4437):1381-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766567" target="_blank"〉PubMed〈/a〉

    Epileptiform burst afterhyperolarization: calcium-dependent potassium potential in hippocampal CA1 pyramidal cells (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-12-05
    Description: Synaptic excitation of hippocampal cells during blockade of synaptic inhibition results in an epileptiform "burst" potential followed by a prolonged afterhyperpolarization. This afterhyperpolarization resembles the one that is seen after the epileptic interictal spike and that is considered of critical importance in preventing seizure development. The afterhyperpolarization produced in the presence of y-aminobutyric acid antagonists is associated with a conductance increase and is inhibitory. It can occur in an all-or-none fashion after a burst, is independent of chloride, and is depressed by barium. The afterhyperpolarization has a reversal potential of (-86) millivolts, and the reversal potential is strongly dependent on the extracellular concentration of potassium. The afterhyperpolarization appears to be an intrinsic, inhibitory potassium potential mediated by calcium. This finding has implications for understanding the cellular mechanisms of epilepsy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alger, B E -- Nicoll, R A -- 9 F32 NS05744-02/NS/NINDS NIH HHS/ -- GM-23478/GM/NIGMS NIH HHS/ -- NS-00287/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Dec 5;210(4474):1122-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444438" target="_blank"〉PubMed〈/a〉

    Description: In view of similarities between the behavioral, biochemical, and electrophysiological effects of amphetamine and stress, we tested the hypothesis that presentation of a stressor, mild tail pressure, can sensitize an animal to the later effects of amphetamine, and vice versa. Our findings supported this hypothesis and suggest that amphetamine and at least some stressors may be interchangeable in their ability to induce a sensitization. The data raise the possibility that stress might be a common variable contributing to both amphetamine psychosis and some forms of schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Antelman, S M -- Eichler, A J -- Black, C A -- Kocan, D -- New York, N.Y. -- Science. 1980 Jan 18;207(4428):329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7188649" target="_blank"〉PubMed〈/a〉

At concentrations of 10 muM or greater this anionic dye produced an irreversible, dose-dependent increase in neurotransmitter release. This increase did not depend on the presence of calcium ions in the bathing medium. These increase did not depend on the presence of calcium ions in the bathing medium.

In particular, the thalassemia syndromes and related disorders of man are inherited anemias that provide mutations for the study of the regulation of globin gene expression. New methods, including restriction enzyme analysis and cloning of cellular DNA, have made it feasible to define more precisely the structure and organization of the globin genes in cellular DNA. Deletions of specific globin gene fragments have already been found in certain of these disorders and have been applied in prenatal diagnosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bank, A -- Mears, J G -- Ramirez, F -- New York, N.Y. -- Science. 1980 Feb 1;207(4430):486-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352255" target="_blank"〉PubMed〈/a〉

    Antibody to spermine: a natural biological constituent (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-06
    Description: A protein that binds spermine specifically was separated from normal rabbit serum by affinity chromatography. Immunoelectrophoresis, the Ouchterlony immunodiffusion test, and gradient gel electrophoresis indicated that this protein has immunoglobulin characteristics and consists of several populations of antibodies to spermine. These were sequentially released from Sepharose-spermine gel by step-wise elution with solutions ranging in pH from 4 to 1. The binding constants varied from 5.0 x 10(8) to 11.1 x 10(8) liters per mole. These globulins did not react with monoacetylputrescine, L-ornithine, L-lysine, and histamine. Negligible cross-reactivity was detected with spermidine, putrescine, N8-monoacetylspermidine, cadaverine, and diaminopropane. Since perturbations in polyamine metabolism have been identified in several diseases, the study of extracellular polyamine homeostasis may reveal an important regulatory function for this protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartos, D -- Bartos, F -- Campbell, R A -- Grettie, D P -- Smejtek, P -- New York, N.Y. -- Science. 1980 Jun 6;208(4448):1178-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375929" target="_blank"〉PubMed〈/a〉

    Description: A substantial sex difference in mathematical reasoning ability (score on the mathematics test of the Scholastic Aptitude Test) in favor of boys was found in a study of 9927 intellectually gifted junior high school students. Our data contradict the hypothesis that differential course-taking accounts for observed sex differences in mathematical ability, but support the hypothesis that these differences are somewhat increased by environmental influences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benbow, C P -- Stanley, J C -- New York, N.Y. -- Science. 1980 Dec 12;210(4475):1262-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434028" target="_blank"〉PubMed〈/a〉

    Site-specific X-chromosome rearrangements from hybrid dysgenesis in Drosophila melanogaster (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-01
    Description: When the germ line of Drosophila males is destabilized by a syndrome known as hybrid dysgenesis, X-chromosome rearrangements are found in up to 10 percent of the gametes produced. Some of these aberrations are simple inversions, but many are complex multibreak rearrangements. Furthermore, most of the breakpoints fall into a few highly localized positions on the chromosome. These positions are mostly at points of intercalary heterochromatin and may vary from one strain to the next. the results suggest that they may represent points of insertion of mobile DNA sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berg, R -- Engels, W R -- Kreber, R A -- GM 07131/GM/NIGMS NIH HHS/ -- GM 22038/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct;210(4468):427-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6776625" target="_blank"〉PubMed〈/a〉

    Adrenocorticotropic hormone may be transported directly from the pituitary to the brain (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-31
    Description: Experiments were designed to test the hypothesis that pituitary hormones may be delivered directly to the brain. Concentrations of adrenocorticotropic hormone (ACTH) in the plasma were determined in blood samles obtained simultaneously from the carotid artery, the sagittal sinus, and the jugular vein of three awake sheep. Seizures were induced electrically to stimulate ACTH secretion, and at precise intervals thereafter several simultaneous comparisons were made in each animal. In many of the post-seizure comparisons, the ACTH plasma concentrations within the sagital sinus exceeded those within the carotid artery as well as those within the jugular vein, indicating that this hormone was released from the pituitary and carried directly through capillary beds of brain to the venous blood within the sagittal sinus. The experiment was repeated in one hypophysectomized sheep and, in this animal, ACTH concentration in the plasma was reduced, but that in the sagittal sinus still was elevated after the seizure, an indication that some ACTH (or ACTH-like material) was released from the brain itself.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergland, R -- Blume, H -- Hamilton, A -- Monica, P -- Paterson, R -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):541-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6252607" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-07-18
    Description: Anorexia can occur when a specific diet is associated with a developing illness. The studies reported here show that the decline in food intake which accompanies tumor growth is accompanied by the development of aversions to the specific diet consumed during tumor growth. An immediate elevation in food consumption occurred when a novel diet was introduced. Therefore, the development of learned aversions to the specific diet eaten during tumor growth may be a causal factor in the development of tumor anorexia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernstein, I L -- Sigmundi, R A -- New York, N.Y. -- Science. 1980 Jul 18;209(4454):416-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6930106" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-05-09
    Description: Moderate chronic malnutrition has only a minor effect on fecundity (reproductive capacity), and the resulting effect on fertility (actural reproduction) is very small. Among the fecundity components examined here in noncontracepting populations, age at menarche and the duration of lactational amenorrhea appear to be the ones most affected by malnutrition. But from neither of those effects can a difference in fertility of more than a few percent be expected between poorly and well-nourished women in developing countries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bongaarts, J -- New York, N.Y. -- Science. 1980 May 9;208(4444):564-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367878" target="_blank"〉PubMed〈/a〉

    Hormone accumulation in a sexually dimorphic motor nucleus of the rat spinal cord (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-31
    Description: The fifth and sixth lumbar segments of the rat spinal cord were found to contain a sexually dimorphic nucleus, the spinal nucleus of the bulbocavernosus (SNB). The SNB, which contains motoneurons innervating perineal striated muscles in normal male rats, is adiminished or absent in normal females and in males with a genetic mutation rendering them insensitive to androgens. The presence of the nucleus is apparently not dependent on genetic sex, but on the action of androgens. The motoneurons of the adult male SNGH accumulate hormone after systemic injections of radioactive testosterone or dihydrotestosterone, but not estradiol, and the SNB motoneurons accumulate more of the injected androgens than do other motoneurons in the same spinal segments. These results demonstrate a morphological sex difference in hormone-sensitive motoneurons that are probably involved in the sexually dimorphic copulatory behavior of the rat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breedlove, S M -- Arnold, A P -- 5-S07/PHS HHS/ -- RR07009-14/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):564-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7423210" target="_blank"〉PubMed〈/a〉

    Histamine-mediated delayed permeability response after scald burn inhibited by cimetidine or cold-water treatment (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-15
    Description: Scald injury to one ear of the hairless mouse induced significant (P 〈 .05) delayed edema formation in remote, uninjured skin. This remote edema formation was completely inhibited by immediate cold-water treatment of the scalded ear. Cold-water treatment significantly reduced histamine loss from the scalded ear, and the edema-inhibiting effect of the treatment could be mimicked by treating the animal prior to injury with the H2-histamine receptor antagonist cimetidine or a drug that causes histamine depletion. These observations suggest (i) that a histamine-mediated, delayed permeability response occurs after thermal injury that causes remote edema formation and (ii) that one mechanism of remote edema inhibition by cold-water treatment is the prevention of histamine release from thermally injured tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boykin, J V Jr -- Eriksson, E -- Sholley, M M -- Pittman, R N -- New York, N.Y. -- Science. 1980 Aug 15;209(4458):815-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6157189" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-02-29
    Description: Pairs of hybridizable species of Hawaiian picture-winged Drosophila differ qualitatively in the distributions of specific enzymes in their tissues. An examination of the patterns of enzyme expression in the hybrids showed that, in three instances, absence of an enzyme from a specific tissue was dominant to presence. Since other developmental features indicated that both parental genomes were functioning, these results suggest that, in these cases, the pattern differences in the parental species were due to diffusible factors that affected expression of the relevant structural genes rather than to differences in the genes themselves or in cis-acting regulatory sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dickinson, W J -- New York, N.Y. -- Science. 1980 Feb 29;207(4434):995-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7352303" target="_blank"〉PubMed〈/a〉

    Description: Using chromosome heteromorphisms and blood cell types as genetic markers, we demonstrated chimerism in a chi46,XX/46,XY true hermaphrodite. The pattern of inheritance of the chromosome heteromorphisms indicates that this individual was probably conceived by the fertilization, by two different spermatozoa, of an ovum and the second meiotic division polar body derived from the ovum and subsequent fusion of the two zygotes. This conclusion is based on the identification of the same maternal chromosomes 13, 16, and 21 in both the 46,XX and 46,XY cells of the patient. In the two cell lines of the chimera, chromosomal markers showed different paternal No. 9 chromosomes and sex chromosomes, as well as the same paternal chromosome 22.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dewald, G -- Haymond, M W -- Spurbeck, J L -- Moore, S B -- New York, N.Y. -- Science. 1980 Jan 18;207(4428):321-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7350665" target="_blank"〉PubMed〈/a〉

    Sparing of the brain in neonatal undernutrition: amino acid transport and incorporation into brain and muscle (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-22
    Description: Rates of tyrosine and lysine transport and incorporation into protein were measured in control and undernourished weanling rats. Undernutrition was induced by feeding lactating dams a low protein diet (12 percent casein) from birth to day 21. At weaning, body and brain weights of undernourished rats were 50 percent and 88 percent, respectively, of control values. Lysine and tyrosine transport rates into skeletal muscle were reduced by over 75 percent, more than twice the reduction seen in brain. Rates of amino acid incorporation into muscle protein were reduced by approximately 50 percent; the change in rate of incorporation into brain protein was not statistically significant. These data indicate that, in spite of marked retardation of amino acid transport into brain, the brain seems fully capable of maintaining normal rates of protein synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freedman, L S -- Samuels, S -- Fish, I -- Schwartz, S A -- Lange, B -- Katz, M -- Morgano, L -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):902-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766565" target="_blank"〉PubMed〈/a〉

    Ala-Gly- and Val-Asp-[Arg8]-vasopressin: bovine storage forms of arginine vasopressin with natriuretic activity (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-22
    Description: Extracts of fresh-frozen bovine neurohypophysis were purified by chromatographic techniques to isolate and characterize the components that produce natriuresis in nondiuretic dogs. Two compounds with natiuretic properties similar to those of synthetic arginine vasopressin accounted for most of the natriuretic activity and appeared to be the prevalent vasopressin-like molecules in the extract. These peptides were Ala-Gly-[Arg8]-vasopressin and Val-Asp-[Arg8]-vasopressin; the natriuretic potency of each appeared to be similar to synthetic arginine vasopressin and could be observed with doses in the range of 50 picomoles. In the dog the most conspicuous difference between synthetic arginine vasopressin and the new vasopressin peptides was the smaller pressor responses to natriuretic doses of the new compounds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gitelman, H J -- Klapper, D G -- Alderman, F R -- Blythe, W B -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):893-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355269" target="_blank"〉PubMed〈/a〉

    Classical conditioning: induction of luteinizing hormone and testosterone secretion in anticipation of sexual activity (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-28
    Description: A classical conditioning paradigm was used to demonstrate that male rats can learn to secrete luteinizing hormone and testosterone in anticipation of sexual activity. Sexually naive males were exposed to a neutral stimulus and then to a sexually receptive female once daily. After exposure to the paired stimuli for 14 trials, the neutral stimulus was as effective as the female in triggering luteinizing hormone and testosterone secretion. These findings provide two novel perspectives on the control of reproductive hormone secretion in male rats: (i) environmental cues, which males learn to associate with sexual activity, induce the secretion of hormones that regulate pituitary-testis function, and (ii) classical conditioning may be used as a noninvasive method to evoke functional alterations in the secretion of luteinizing hormone and presumably the neuroendocrine pathways that mediate its release.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graham, J M -- Desjardins, C -- HD-13470/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):1039-41.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7434016" target="_blank"〉PubMed〈/a〉

    Description: Sex steroid hormones and catecholamines have physiological interactions in the brain. By the combined use of autoradiography and fluorescence histochemistry, steroid hormone target sites and catecholamine neurons were visualized simultaneously in the same tissue preparation. By this dual localization method, [3H]estradiol and [3H]dihydrotestosterone target sites were identified in nuclei of many catecholamine cell bodies in the brainstem, and catecholamine nerve terminals were observed near certain steroid hormone target neurons. These results suggest close anatomical interrelations between steroid hormone sites of action and catecholamine sites of production and action in the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heritage, A S -- Stumpf, W E -- Sar, M -- Grant, L D -- New York, N.Y. -- Science. 1980 Mar 21;207(4437):1377-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355296" target="_blank"〉PubMed〈/a〉

    Feeding increases dopamine metabolism in the rat brain (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-06
    Description: Feeding induced by food deprivation is accompanied by an increased production of the dopamine metabolite 3,4-dihydroxyphenylacetic acid in the brains of rats. This neurochemical change occurs in the nucleus accumbens, the posterior hypothalamus, and the amygdala but not in other dopaminergic nerve terminal fields such as the corpus striatum. These results indicate that the release of dopamine from particular groups of central neurons is increased during feeding and suggest that anatomically distinct subgroups of central dopaminergic neurons serve different roles in the regulation of food intake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heffner, T G -- Hartman, J A -- Seiden, L S -- New York, N.Y. -- Science. 1980 Jun 6;208(4448):1168-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375926" target="_blank"〉PubMed〈/a〉

    Description: Arylazido aminopropionyl adenosine triphosphate (ANAPP3), a photoaffinity label, antagonized specifically adenine nucleotide-induced contractions of the guinea pig vas deferens. Irradiation of tissues with visible light in the presence of ANAPP3 resulted in an irreversible antagonism, which was prevented when adenosine triphosphate was present. In the absence of light, the antagonism was reversible and may have resulted from an autoinhibition phenomenon. Responses to acetylcholine, histamine, norepinephrine, and potassium chloride were not affected by ANAPP3.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hogaboom, G K -- O'Donnell, J P -- Fedan, J S -- New York, N.Y. -- Science. 1980 Jun 13;208(4449):1273-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6103581" target="_blank"〉PubMed〈/a〉

    DNA gyrase and the supercoiling of DNA (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-02-29
    Description: Negative supercoiling of bacterial DNA by DNA gyrase influences all metabolic processes involving DNA and is essential for replication. Gyrase supercoils DNA by a mechanism called sign inversion, whereby a positive supercoil is directly inverted to a negative one by passing a DNA segment through a transient double-strand break. Reversal of this scheme relaxes DNA, and this mechanism also accounts for the ability of gyrase to catenate and uncatenate DNA rings. Each round of supercoiling is driven by a conformational change induced by adenosine triphosphate (ATP) binding: ATP hydrolysis permits fresh cycles. The inhibition of gyrase by two classes of antimicrobials reflects its composition from two reversibly associated subunits. The A subunit is particularly associated with the concerted breakage-and-rejoining of DNA and the B subunit mediates energy transduction. Gyrase is a prototype for a growing class of prokaryotic and eukaryotic topoisomerases that interconvert complex forms by way of transient double-strand breaks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cozzarelli, N R -- New York, N.Y. -- Science. 1980 Feb 29;207(4434):953-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243420" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-09-19
    Description: Phase variation in bacteria is regulated by homologous recombination at a specific DNA site. This recombinational event causes the inversion of a 970-base-pair DNA sequence that includes the promoter necessary for transcription of a flagellar gene. The invertible segment is flanked by two sites that are necessary for the inversion and contains a gene (hin) whose product mediates the inversion event. The hin gene shows extensive homology with the TnpR gene carried on the Tn3 transposon. It is also homologous with the gin gene carried on bacteriophage mu. These relationships suggest that the phase variation system may have evolved by the association of a transposon with a resident gene and the subsequent specialization of these elements to regulate flagellar antigen expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simon, M -- Zieg, J -- Silverman, M -- Mandel, G -- Doolittle, R -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1370-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251543" target="_blank"〉PubMed〈/a〉

The results demonstrate the essential role of gonadotropin-releasing hormone in the maintenance of reproductive functions and have implications for the regulation of male fertility.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivier, C -- Rivier, J -- Vale, W -- HD09690/HD/NICHD NIH HHS/ -- RFP CD-78-5/FP/OFP OPHS HHS/ -- New York, N.Y. -- Science. 1980 Oct 3;210(4465):93-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6774418" target="_blank"〉PubMed〈/a〉

    Magnesium deficiency produces spasms of coronary arteries: relationship to etiology of sudden death ischemic heart disease (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-11
    Description: Isolated coronary arteries from dogs were incubated in Krebs-Ringer bicarbonate isolation and exposed to normal, high, and low concentrations of magnesium in the medium. Sudden withdrawal of magnesium from the medium increased whereas high concentrations of magnesium decreased the basal tension of the arteries. The absence of magnesium in the medium significantly potentiated the contractile responses of both small and large coronary arteries to norepinephrine, acetylcholine, serotonin, angiotensin, and potassium. These data support the hypothesis that magnesium deficiency, associated with sudden death ischemic heart disease, produces coronary arterial spasm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turlapaty, P D -- Altura, B M -- New York, N.Y. -- Science. 1980 Apr 11;208(4440):198-200.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7361117" target="_blank"〉PubMed〈/a〉

    Carboxyhemoglobin levels in an unstable hemoglobin disorder (Hb Zurich): effect on phenotypic expression (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-18
    Description: The affinity of Hb Zurich for carbon monoxide is approximately 65 times that of normal hemoglobin. The carboxyhemoglobin content in serum from individuals with Hb Zurich ranged from 3.9 to 6.7 percent in nine nonsmokers and from 9.8 to 19.7 percent in six smokers. Rates of hemolysis and hemoglobin denaturation were less in smokers than in nonsmokers, effects that may be secondary to the stabilization of Hb Zurich by carbon monoxide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zinkham, W H -- Houtchens, R A -- Caughey, W S -- New York, N.Y. -- Science. 1980 Jul 18;209(4454):406-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384813" target="_blank"〉PubMed〈/a〉

    Two coronaviruses isolated from central nervous system tissue of two multiple sclerosis patients (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-22
    Description: Two coronaviruses were isolated from brain material obtained at autopsy from two multiple sclerosis patients. The viruses were neutralized by serum and spinal fluid from these patients. Although most of the population have antibody to these virus isolates, multiple sclerosis patients have slightly higher concentrations of serum antibody than controls. The results suggest that coronaviruses should be considered as one additional virus with a potential implication in the etiology of multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burks, J S -- DeVald, B L -- Jankovsky, L D -- Gerdes, J C -- New York, N.Y. -- Science. 1980 Aug 22;209(4459):933-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403860" target="_blank"〉PubMed〈/a〉

    Insulin receptors in hepatocytes: postreceptor events mediate down regulation (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-28
    Description: Down regulation of the insulin receptor of primary cultures of rat hepatocytes occurs in the presence of insulin and several agents with insulin-like activity, which act through or distal to the insulin receptor. These findings indicate that the interaction of insulin with its specific binding site is not in itself sufficient to down-regulate this receptor and that one or more steps subsequent to this interaction are necessary. Thus, down regulation may be a complex biological response to insulin, and if a cell were resistant to this effect of insulin, our data may explain how target cells from a patient or animal can have a normal number of receptors in the presence of increased concentrations of circulating insulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caro, J F -- Amatruda, J M -- AM 00366/AM/NIADDK NIH HHS/ -- AM 20948/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 28;210(4473):1029-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7001632" target="_blank"〉PubMed〈/a〉

    Subcellular origin of cholinergic transmitter release from mouse brain (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-07
    Description: Samples of minced mouse forebrain were treated in a way that resulted in a high ratio of false cholinergic transmitter (acetylhomocholine) to true transmitter (acetylcholine) in a synaptic vesicle fraction, and a low ratio of false to true transmitter in the nerve terminal cytoplasm. The spontaneous release of cholinergic transmitters from this minced tissue occurred independently of calcium and had a ratio of false to true transmitter similar to that of the cytoplasm, whereas the evoked transmitter release required calcium and had a ratio of false to true transmitter similar to that of the vesicular fraction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carroll, P T -- Aspry, J M -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):641-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7433989" target="_blank"〉PubMed〈/a〉
