    Local effects of partly cloudy skies on solar and emitted radiations (1981)
    In:  CASI
    Details
    Publikationsdatum: 2019-07-13
    Beschreibung: Solar radiation measurements are made on a routine basis. Global solar, atmospheric emitted, downwelled diffuse solar, and direct solar radiation measurement systems are fully operational with the first two in continuous operation. Fractional cloud cover measurements are made from GOES imagery or from ground based whole sky photographs. Normalized global solar irradiance values for partly cloudy skies were correlated to fractional cloud cover.

    A crustacean statocyst with only three hairs: Light and scanning electron microscopy (1981)

    Notizen: Standard histological and SEM techniques have been used to examine the pair of statocyst organs located in the telson of the isopod, Cyathara polita. Each organ is formed as an invagination of the dorsal cuticle of the telson. The invagination narrows to form a stalk between the statocyst and dorsal surface. A canal courses longitudinally through this stalk and forms a continuous channel between the lumen of the cyst and the external environment. On the luminal floor of each statocyst, there are three pits; each correlates with a nodule protruding from the ventro-medial wall. From each pit, a single, bifurcating hair projects dorsally to contact the single concretion within the statocyst lumen. No other static organs have been found in this animal. Thus, maintenance of equilibrium in this species appears to be under the control of but six hairs, three in each statocyst. Innervation of each statocyst is provided by a branch of a nerve which connects anteriorly with the last abdominal ganglion.

    Chronic exposure to 60-Hz electric fields: Effects on pineal function in the rat (1981)
    New York, NY [u.a.] : Wiley-Blackwell

    Notizen: As a component of studies to search for effects of 60-Hz electric field exposure on mammalian endocrine function, concentrations of melatonin, 5-methoxytryptophol, and serotonin-Nacetyl transferase activity were measured in the pineal glands of rats exposed or sham-exposed at 65 kV/m for 30 days. In two replicate experiments there were statistically significant differences between exposed and control rats in that the normal nocturnal increase in pineal melatonin content was depressed in the exposed animals. Concentrations of 5-methoxytryptophol were increased in the pineal glands of the exposed groups when compared to shamexposed controls. An alteration was also observed in serotonin-N-acetyl transferase activity, with lower levels measured in pineal glands from exposed animals.

    Growth and metabolism of rodents exposed to 60-Hz electric fields (1981)
    New York, NY [u.a.] : Wiley-Blackwell
    Bioelectromagnetics 2 (1981), S. 381-390 
    Details
    ISSN: 0197-8462
    Schlagwort(e): 60-Hz electric fields ; body weight ; oxygen consumption ; rat ; mouse ; Life and Medical Sciences ; Occupational Health and Environmental Toxicology

    Thema: Biologie , Physik
    Notizen: There have been a number of reports in the literature concerning growth-related changes in various animal species exposed to high-strength electric fields. Many of the laboratories reporting such effects have not documented and controlled for the secondary factors that are associated with generating high-strength electric fields (ie, corona, ozone, harmonic distortion, cage vibration, spark discharge). We have designed an exposure system in which we eliminated or minimized these secondary factors, therefore enabling us to examine only the effects of electric fields per se. Sprague-Dawley rats and Swiss-Webster mice were exposed to 60-Hz electric fields at kV/m for up to four months. In 17 individual experiments, we found a greater number of experiments in which the exposed rats had lower body weights than controls. This trend was not evident in data obtained from 14 individual mouse experiments. In more exhaustive growth studies, we found no significant differences in body weights, organ weights, or O2 consumption between exposed and sham-exposed controls. Our failure to detect any major changes in growth was probably the result of eliminating or minimizing the secondary factors associated with electric field exposure.

    Influence of homoeotic genes on the aldehyde oxidase pattern in imaginal discs of Drosophila melanogaster (1981)
    Chichester [u.a.] : Wiley-Blackwell
    Developmental Genetics 2 (1981), S. 75-87 
    Details
    ISSN: 0192-253X
    Schlagwort(e): Drosophila melanogaster ; homoeosis ; imaginal discs ; aldehyde oxidase ; pattern formation ; compartments ; selector genes ; Life and Medical Sciences ; Genetics
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Biologie
    Notizen: In a study of the regulation of enzyme patterns in imaginal discs the aldehyde oxidase pattern was determined for some homoeotic mutations of D. melanogaster. Earlier indications that suggested that this pattern follows the determinitive state of compartments within imaginal discs were confirmed by the aldehyde oxidase (AO) pattern of both the wing and haltere discs from en1; bx3, en1; pbx, and en1; bx3 pbx larvae and the antennal discs from Antp73b and ssa larvae.We additionally analyzed whether AO activity depended on the determinative state of an entire compartment or was expressed autonomously in clones. Homozygous engrailed clones were induced by mitotic recombination. From the AO clones found in normally negative areas of the posterior compartment it was concluded that enzyme activity depended upon the determinative state of the cells and was not a function of the compartment as a whole.The results are described with reference to a scheme in which compartmental and subcompartmental selector genes are thought to determine a binary code on which AO patterns depend.

    Persistent behavior at high rates maintained by intravenous self-administration of nicotine (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-10-30
    Beschreibung: Squirrel monkeys pressed a level at high rates under a second-order schedule of reinforcement in which level pressing produced a brief visual stimulus that was occasionally contiguous with an intravenous injection of nicotine. The rate of lever pressing could be markedly reduced either by substituting saline for nicotine injections or by blocking the effects of nicotine with mecamylamine. The rate of level pressing could be reduced by eliminating the brief visual stimulus. These results show that nicotine can function as an effective reinforcer under a second-order schedule of drug self-administration and that an environmental stimulus associated with nicotine intake can contribute to the maintenance of persistent drug-seeking behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldberg, S R -- Spealman, R D -- Goldberg, D M -- DA00499/DA/NIDA NIH HHS/ -- DA02658/DA/NIDA NIH HHS/ -- MH07658/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):573-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291998" target="_blank"〉PubMed〈/a〉

    Tonic immobility produces hyperalgesia and antagonizes morphine analgesia (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-07-17
    Beschreibung: Hyperalgesia was demonstrated during and immediately after termination of tonic immobility in the lizard Anolis carolinensis. Additionally, tonic immobility antagonized morphine-induced analgesia. In conjunction with other research, these data suggest that the response is accompanied by a reduced availability of serotonin, possibly at postsynaptic receptors of raphe neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mauk, M D -- Olson, R D -- LaHoste, G J -- Olson, G A -- New York, N.Y. -- Science. 1981 Jul 17;213(4505):353-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244620" target="_blank"〉PubMed〈/a〉

    Beschreibung: A genetically determined deficiency of the third component of complement (C3) has been identified in a colony of Brittany spaniels. Immunochemical methods show no detectable C3 in the serum of the affected dogs, and there is no evidence of an inhibitor of C3 in the serum. The C3 deficiency appears to be transmitted as an autosomal recessive trait.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winkelstein, J A -- Cork, L C -- Griffin, D E -- Griffin, J W -- Adams, R J -- Price, D L -- AI-11637/AI/NIAID NIH HHS/ -- NS-10580/NS/NINDS NIH HHS/ -- RR-00130/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233211" target="_blank"〉PubMed〈/a〉

    Power spectrum analysis of heart rate fluctuation: a quantitative probe of beat-to-beat cardiovascular control (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-07-10
    Beschreibung: Power spectrum analysis of heart rate fluctuations provides a quantitative noninvasive means of assessing the functioning of the short-term cardiovascular control systems. We show that sympathetic and parasympathetic nervous activity make frequency-specific contributions to the heart rate power spectrum, and that renin-angiotensin system activity strongly modulates the amplitude of the spectral peak located at 0.04 hertz. Our data therefore provide evidence that the renin-angiotensin system plays a significant role in short-term cardiovascular control in the time scale of seconds to minutes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akselrod, S -- Gordon, D -- Ubel, F A -- Shannon, D C -- Berger, A C -- Cohen, R J -- HL 19467/HL/NHLBI NIH HHS/ -- SO7 RR 07047/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):220-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6166045" target="_blank"〉PubMed〈/a〉

    Differentiation of murine bone marrow stem cells in vitro: long-term growth promoted by a lymphocyte-derived mediator (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-01-02
    Beschreibung: In attempts to induce differentiation of lymphoid cells from hematopoietic stem cells in vitro, the effects of allogeneic effect factor on the growth of murine bone marrow cultures were studied. Allogeneic effect factor is a soluble mediator derived from mixed secondary murine leukocyte cultures. For several weeks it supported the growth of bone marrow cultures, as indicated by the maintenance of stem cell activity, cellular proliferation, and heterogeneity. Another lymphokine, T cell growth factor, did not, Pre-T lymphocytes could be detected in these cultures for several weeks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altman, A -- Gilmartin, T D -- Katz, D H -- CA-25803/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 2;211(4477):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6934621" target="_blank"〉PubMed〈/a〉
