    Ferritin synthesis by human T lymphocytes (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-29
    Description: Mononuclear cells from peripheral blood of normal humans, unselected spleen cells from patients with Hodgkin's disease, and selected T and non-T lymphoid cells from normal peripheral blood and from the spleens of Hodgkin's disease patients were examined for de novo synthesis and secretion of ferritin. After precipitation of labeled lysates and supernatants from unseparated and selected T cells with antiserum to human liver ferritin, two bands were visible on sodium dodecyl sulfate-polyacrylimide gel analysis. The two bands were detected in molecular weight regions 19,000 and 21,000, which are thought to represent the L and H subunits of the ferritin molecule, respectively. The slower band (subunit H) was more radioactive than the faster band (subunit L). The H subunit is found in greater amounts in the serum of some tumor patients, but its cellular origin has not been established. The present findings indicate that cells of the immune system contribute to the synthesis and secretion of a ferritin molecule with a high proportion of H subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorner, M H -- Silverstone, A -- Nishiya, K -- de Sostoa, A -- Munn, G -- de Sousa, M -- New York, N.Y. -- Science. 1980 Aug 29;209(4460):1019-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6967622" target="_blank"〉PubMed〈/a〉

    Strain dependence of the antiproliferative action of interferon on murine erythroid precursors (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-07-11
    Description: Electrophoretically pure mouse interferon inhibits erythropoietin-dependent proliferation of committed erythroid precursors (CFU-E) obtained either from adult mouse bone marrow or from 14-day fetal mouse livers. The degree of inhibition is significantly influenced by the genotype of the cell donor; about ten times as much interferon is required to inhibit proliferation of CFU-E from C57BL/6 than is needed for comparable inhibition of CFU-E from BALB/c or Swiss mice. These strain-dependent results point to the existence of genes that influence the degree of the inhibitory effect of interferon on cell multiplication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallien-Lartigue, O -- Carrez, D -- De Maeyer, E -- De Maeyer-Guignard, J -- New York, N.Y. -- Science. 1980 Jul 11;209(4453):292-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6155700" target="_blank"〉PubMed〈/a〉

    Recognition of HLA-A2 by cytotoxic T lymphocytes after DNA transfer into human and murine cells (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-11-30
    Description: A gene coding for the major histocompatibility antigen HLA-A2 was transferred into human HLA-A2 negative M1 cells and murine L cells. Following transfection, these cells expressed molecules at the cell surface that are biochemically indistinguishable from HLA-A2 antigens on the human cell line JY from which the HLA-A2 gene was isolated. The M1A2 cells were recognized and lysed by a cytolytic T-cell clone specific for HLA-A2. The transfected L cells which express HLA-A2 in association with human beta 2-microglobulin were not lysed by this T-cell clone. The specific cytolysis of M1A2 cells could be inhibited by monoclonal antibodies to HLA-A2, and monoclonal antibodies to T3, T8, and LFA-1 on cytotoxic T lymphocytes. These results suggest that killing by allospecific T cells requires HLA-A2 antigens as well as other species-specific structures on the target cell surface.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van de Rijn, M -- Bernabeu, C -- Royer-Pokora, B -- Weiss, J -- Seidman, J G -- de Vries, J -- Spits, H -- Terhorst, C -- AI 19148/AI/NIAID NIH HHS/ -- AI-15066/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1083-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6333726" target="_blank"〉PubMed〈/a〉

    The diaphragm: two muscles (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-10
    Description: The costal and crural parts of the diaphragm were separately stimulated in anesthetized dogs. Stimulation of the costal part increased the dimensions of the lower rib cage, whereas stimulation of the costal part decreased the dimensions of the lower rib cage. It is concluded that the diaphragm consists of two muscles that act differently on the rib cage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Troyer, A -- Sampson, M -- Sigrist, S -- Macklem, P T -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):237-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244632" target="_blank"〉PubMed〈/a〉

    Platelet thromboxane synthetase inhibitors with low doses of aspirin: possible resolution of the "aspirin dilemma" (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-29
    Description: Selective pharmacological inhibition of thromboxane A2 synthesis did not prevent arachidonate-induced aggregation of human platelets in vitro. Prevention was instead achieved by a combination of thromboxane A2 inhibitors with low concentrations of aspirin. The latter partially reduced the proaggregatory cyclooxygenase products that accumulated when thromboxane A2 synthesis was blocked. The aspirin concentrations did not affect per se either platelet aggregation or prostacyclin synthesis in cultured human endothelial cells. The combination of thromboxane synthetase inhibitors with low doses of aspirin may offer greater antithrombotic potential than either drug alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bertele, V -- Falanga, A -- Tomasiak, M -- Dejana, E -- Cerletti, C -- de Gaetano, G -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):517-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682245" target="_blank"〉PubMed〈/a〉

    Tracking the flow of information (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-08-12
    Description: By using words transmitted and words attended to as common denominators, novel indexes were constructed of growth trends in 17 major communications media from 1960 to 1977. There have been extraordinary rates of growth in the transmission of electronic communications, but much lower rates of growth in the material that people actually consume, representing the phenomenon often labeled information overload. Growth in print media has sharply decelerated, and a close relationship is found between the cheapness of a medium and its rate of growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Sola Pool, I -- New York, N.Y. -- Science. 1983 Aug 12;221(4611):609-13.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17787717" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-04-01
    Description: The external and internal interosseous intercostal muscles were separately stimulated at end-expiratory lung volume in anesthetized dogs. These muscles were all found to elevate the ribs into which they insert. By attaching weights to the ribs, it was determined that the nonlinear compliance of the ribs was responsible for this phenomenon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Troyer, A -- Kelly, S -- Zin, W A -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):87-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828883" target="_blank"〉PubMed〈/a〉

    Functional organization of the second cortical visual area in primates (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-05-13
    Description: The functional organization of the second cortical visual area was examined with three different anatomical markers: 2-[14C]deoxy-D-glucose, cytochrome oxidase, and various myelin stains. All three markers revealed strips running throughout the area, parallel to the cortical surface. The boundaries of these strips provide an anatomical criterion for defining the borders of this extrastriate region. Further, the demonstration of these strips allows a functional and anatomical analysis of modules in the area, just as the recent demonstration of spots in the primary visual cortex has allowed an analysis of modules there. The strips differ structurally and functionally from interstrip regions and these differences are similar to those seen between the spots and the interspot regions in the primary visual cortex. In the macaque the strips and spots differ with regard to binocular organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tootell, R B -- Silverman, M S -- De Valois, R L -- Jacobs, G H -- EY-00014/EY/NEI NIH HHS/ -- EY-02052/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 13;220(4598):737-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301017" target="_blank"〉PubMed〈/a〉

    Synapsin I in nerve terminals: selective association with small synaptic vesicles (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-12-07
    Description: Immunocytochemistry revealed that synapsin I is preferentially (and possibly exclusively) associated with small (40- to 60-nanometer) synaptic vesicles and not with large (greater than 60-nanometer) dense-core vesicles in bovine hypothalamus. These observations may explain why synapsin I is found exclusively in neurons, since small synaptic vesicles are specific to neurons whereas large dense-core vesicles in neurons may be considered the equivalent of secretory organelles in endocrine cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Navone, F -- Greengard, P -- De Camilli, P -- MH 17387/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1984 Dec 7;226(4679):1209-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6438799" target="_blank"〉PubMed〈/a〉
