    Ozone and temperature trends associated with the 11-year solar cycle (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-06-22
    Description: Evidence is presented which suggests that trends in the ozone concentration and stratospheric temperature, reported between the early 1960's and 1976, are to a large extent due to solar ultraviolet flux variability associated with the 11-year solar cycle. Radiative-convective-photochemical simulations of ozone and temperature variations have been made with a solar ultraviolet flux variability model. Results for temperatures and ozone concentrations, when compared with published data, show good agreement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Callis, L B -- Natarajan, M -- Nealy, J E -- New York, N.Y. -- Science. 1979 Jun 22;204(4399):1303-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17813169" target="_blank"〉PubMed〈/a〉

    Shifts in perception of size after adaptation to gratings (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: After viewing a suitable grating of vertical stripes for 5 minutes, subjects overestimated the width of a rectangle by 6 percent. The shifts in perception of size occurred whether individual stripes in the grating were narrower than, equal to, or wider than the rectangle. Rectangle width was underestimated only if the grating stripes were extremely wide, with a spatial frequency lower than most of the effective amplitude spectrum of the rectangle. These findings (and complementary ones with horizontal gratings) suggest that the visual system codes size on the basis of spatial frequency components, rather than directly in terms of width.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frome, F S -- Levinson, J Z -- Danielson, J T -- Clavadetscher, J E -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1327-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/515736" target="_blank"〉PubMed〈/a〉

    Cigarette smoking induces functional antiprotease deficiency in the lower respiratory tract of humans (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: Current concepts of the pathogenesis of emphysema suggest that it results from an imbalance of elastase and antielastase activity within the alveolar structures. Although emphysema that is associated with hereditary deficiency of serum alpha 1-antitrypsin conforms to this scheme, the major risk factor in the more common form of emphysema is cigarette smoking. A study was designed to evaluate the premise that cigarette smoking may be associated with an acquired, functional defect in lung alpha 1-antitrypsin. Determination of the antielastase activity of alpha 1-antitrypsin obtained from the lungs of smoking and nonsmoking individuals revealed a nearly twofold reduction in the functional activity of this elastase inhibitor in the lungs of cigarette smokers. These data suggest that cigarette smokers may lose some of the normal antielastase protective screen of the lower respiratory tract, making them more vulnerable to destructive lung disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gadek, J E -- Fells, G A -- Crystal, R G -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1315-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/316188" target="_blank"〉PubMed〈/a〉

    A correlation between platelet monoamine oxidase activity and plasma prolactin concentrations in man (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-10-26
    Description: Increases in plasma prolactin concentrations produced by alpha-methyl-p-tyrosine, a catecholamine synthesis inhibitor, varied inversely with baseline platelet monoamine oxidase activity in 12 patients with chronic schizophrenia. In normal volunteers with low monoamine oxidase activity and in unmedicated patients with chronic schizophrenia, plasma prolactin concentrations varied directly with platelet monoamine oxidase activity. No such relationship was found in normal subjects with high platelet monoamine oxidase activity. These data suggest that platelet monoamine oxidase activity reflects monoaminergic activity in the tubero-infundibular system, which in turn affects plasma prolactin concentrations. This relationship may be important in patients with low platelet monoamine oxidase activity, such as some chronic schizophrenics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleinman, J E -- Potkin, S -- Rogol, A -- Buchsbaum, M S -- Murphy, D L -- Gillin, J C -- Nasrallah, H A -- Wyatt, R J -- New York, N.Y. -- Science. 1979 Oct 26;206(4417):479-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/504993" target="_blank"〉PubMed〈/a〉

    Receptor-mediated internalization of fluorescent chemotactic peptide by human neutrophils (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-28
    Description: Tetramethylrhodamine labeled N-formyl-Nle-Leu-Phe-Nle-Tyr-Lys is a potent chemoattractant for human neutrophils. Binding of this peptide to living neutrophils was observed by means of video intensification microscopy. At 37 degrees C, diffuse membrane fluorescence was seen initially, followed by rapid aggregation and internalization of the fluorescent peptide. These processes are dependent on specific binding to the formal peptide chemotactic receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Niedel, J E -- Kahane, I -- Cuatrecasas, P -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1412-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472759" target="_blank"〉PubMed〈/a〉

    Publication Date: 1979-04-27
    Description: The strontium to calcium ratio of skeletal aragonite in three genera of reef-building corals varies as a simple function of temperature and the strontium to calcium ratio of the incubation water. The strontiumlcalcium distribution coefficients of coral aragonite apparently differ from the corresponding coefficient of inorganically precipitated aragonite. With some care, coral skeletons can be used as recording thermometers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, S V -- Buddemeier, R W -- Redalje, R C -- Houck, J E -- New York, N.Y. -- Science. 1979 Apr 27;204(4391):404-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17758014" target="_blank"〉PubMed〈/a〉

    Elimination of metabolic cooperation in Chinese hamster cells by a tumor promoter (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-11-30
    Description: Wild-type Chinese hamster V79 cells (6-thioguanine-sensitive) reduce the recovery of 6-thioguanine-resistant cells when they are cultured together at high densities, through a form of intercellular communication (metabolic cooperation). Cooperation is inhibited by 12-O-tetradecanoyl phorbol-13-acetate, rescuing the 6-thioguanine-resistant cells. These results may be useful in the study of an aspect of the mechanism of tumor promotion and in assaying for promoters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yotti, L P -- Chang, C C -- Trosko, J E -- New York, N.Y. -- Science. 1979 Nov 30;206(4422):1089-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/493994" target="_blank"〉PubMed〈/a〉
