    Hyperglycemia of diabetic rats decreased by a glucagon receptor antagonist (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-02-26
    Description: The glucagon analog [l-N alpha-trinitrophenylhistidine, 12-homoarginine]-glucagon (THG) was examined for its ability to lower blood glucose concentrations in rats made diabetic with streptozotocin. In vitro, THG is a potent antagonist of glucagon activation of the hepatic adenylate cyclase assay system. Intravenous bolus injections of THG caused rapid decreases (20 to 35 percent) of short duration in blood glucose. Continuous infusion of low concentrations of the inhibitor led to larger sustained decreases in blood glucose (30 to 65 percent). These studies demonstrate that a glucagon receptor antagonist can substantially reduce blood glucose levels in diabetic animals without addition of exogenous insulin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, D G -- Goebel, C U -- Hruby, V J -- Bregman, M D -- Trivedi, D -- AM21085/AM/NIADDK NIH HHS/ -- AM25318/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Feb 26;215(4536):1115-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6278587" target="_blank"〉PubMed〈/a〉

    Sex and handedness differences in cerebral blood flow during rest and cognitive activity (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-13
    Description: Cognitive activity resulted in increased flow of blood to the cerebral hemispheres. The increase was greater to the left hemisphere for a verbal task and greater to the right hemisphere for a spatial task. The direction and degree of hemispheric flow asymmetry were influenced by sex and handedness, females having a higher rate of blood flow per unit weight of brain, and females and left-handers having a greater percentage of fast-clearing tissue, presumably gray matter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gur, R C -- Gur, R E -- Obrist, W D -- Hungerbuhler, J P -- Younkin, D -- Rosen, A D -- Skolnick, B E -- Reivich, M -- MH 30456/MH/NIMH NIH HHS/ -- NS-10939-09/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089587" target="_blank"〉PubMed〈/a〉

    Radar and infrared remote sensing of geothermal features at Pilgrim Springs, Alaska (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: High-altitude radar and thermal imagery collected by the NASA research aircraft WB57F were used to examine the structural setting and distribution of radiant temperatures of geothermal anomalies in the Pilgrim Springs, Alaska area. Like-polarized radar imagery with perpendicular look directions provides the best structural data for lineament analysis, although more than half the mapped lineaments are easily detectable on conventional aerial photography. Radiometer data and imagery from a thermal scanner were used to evaluate radiant surface temperatures, which ranged from 3 to 17 C. The evening imagery, which utilized density-slicing techniques, detected thermal anomalies associated with geothermal heat sources. The study indicates that high-altitude predawn thermal imagery may be able to locate relatively large areas of hot ground in site-specific studies in the vegetated Alaskan terrain. This imagery will probably not detect gentle lateral gradients.

    Improved definition of crustal magnetic anomalies for MAGSAT data (1982)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: The routine correction of MAGSAT vector magnetometer data for external field effects such as the ring current and the daily variation by filtering long wavelength harmonics from the data is described. Separation of fields due to low altitude sources from those caused by high altitude sources is affected by means of dual harmonic expansions in the solution of Dirichlet's problem. This regression/harmonic filter procedure is applied on an orbit by orbit basis, and initial tests on MAGSAT data from orbit 1176 show reduction in external field residuals by 24.33 nT RMS in the horizontal component, and 10.95 nT RMS in the radial component.

    Comparison of diverse methods for the correction of atmospheric effects on LANDSAT and SKYLAB images (1982)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: Earth's atmosphere reduces a sensors ability in currently discriminating targets. Using radiometric correction to reduce the atmospheric effects may improve considerably the performance of an automatic image interpreter. Several methods for radiometric correction from the open literature are compared leading to the development of an atmospheric correction system.

    Leukotriene D4: a potent coronary artery vasoconstrictor associated with impaired ventricular contraction (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-27
    Description: Leukotriene D4 (2 c 10(-9) mole), injected into the left circumflex coronary artery of anesthetized sheep, produced profound coronary vasoconstriction and impaired regional ventricular wall motion. This cardiac effect was neither inhibited by prior treatment of the sheep with a cyclooxygenase inhibitor nor associated with thromboxane B2 release into the coronary sinus. Intravenous FPL 55712 completely abolished the coronary vasoconstriction of leukotriene D4, but a significant reduction of regional wall shortening persisted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michelassi, F -- Landa, L -- Hill, R D -- Lowenstein, E -- Watkins, W D -- Petkau, A J -- Zapol, W M -- HL23591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 27;217(4562):841-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6808665" target="_blank"〉PubMed〈/a〉

    Role of serotonergic input in the regulation of the beta-adrenergic receptor-coupled adenylate cyclase system (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-26
    Description: The action of desipramine on the norepinephrine-sensitive adenylate cyclase system and the density of beta-adrenergic receptors in rat cortex was studied after selective lesioning of serotonergic neurons with 5,7-dihydroxytryptamine. In animals with lesions desipramine failed to reduce the density of beta-adrenoceptors but decreased the response of adenosine 3',5'-monophosphate to isoproterenol and norepinephrine to the same degree as in animals without lesions. The results demonstrate a functional linkage between serotonergic and noradrenergic systems in the rat cortex, with beta-adrenergic receptors and neurohormonal sensitivity of the adenosine 3',5'-monophosphate-generating system being under separate regulatory control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janowsky, A -- Okada, F -- Manier, D H -- Applegate, C D -- Sulser, F -- Steranka, L R -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):900-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6291152" target="_blank"〉PubMed〈/a〉
