    Contact-mediated bone resorption by human monocytes in vitro (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1978-03-03
    Beschreibung: Human circulating monocytes in tissue culture are capable of resorbing devitalized adult and fetal bone. An important component of this process is the adhesion of the cells to the mineralized substrate and the localized removal of matrix from beneath the attached cells. The process appears to involve both release of lysosomal enzymes onto the substrate and intracellular accumulation (transport) of resorbed matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kahn, A J -- Stewart, C C -- Teitelbaum, S L -- New York, N.Y. -- Science. 1978 Mar 3;199(4332):988-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622581" target="_blank"〉PubMed〈/a〉

    Radioimmunoassay of the insulin receptor: a new probe of receptor structure and function (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1979-02-09
    Beschreibung: A sensitive and specific radioimmunoassay for the insulin receptor has been developed employing receptor autoantibodies from the serum of a patient with insulin-resistant diabetes. The assay detects insulin binding sites at concentrations as low as 0.1 nanomolar; distinguishes between receptors originating from human placental membranes, human lymphoblastoid cells, and mouse liver membranes; and measures the receptor independently of its binding function. Down-regulation, or loss of binding after exposure to insulin, is associated with loss of immunoreactive receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, L C -- Flier, J -- Itin, A -- Kahn, C R -- Roth, J -- New York, N.Y. -- Science. 1979 Feb 9;203(4380):544-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83675" target="_blank"〉PubMed〈/a〉

    Insulin stimulates the phosphorylation of the 95,000-dalton subunit of its own receptor (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1982-01-08
    Beschreibung: Cultured human lymphocytes and rat hepatoma cells were labeled with [32P]orthophosphate and the insulin receptor subunits identified by immunoprecipitation and sodium dodecyl sulfate-gel electrophoreses. In both cell types the 95,000-dalton (beta) subunit of the insulin receptor was selectively phosphorylated. Phosphorylation was specifically stimulated by insulin in a dose-dependent fashion after 1 and 15 minutes of hormone treatment, whereas human growth hormone was without effect. This phosphorylation may be a very early event in insulin action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasuga, M -- Karlsson, F A -- Kahn, C R -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):185-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7031900" target="_blank"〉PubMed〈/a〉

    Monocyte chemotaxis: stimulation by specific exosite region in thrombin (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-05-13
    Beschreibung: Human alpha-thrombin is a potent chemoattractant for human monocytes, with optimum activity occurring at about 10 nanomoles per liter. A variety of thrombins that were chemically modified to alter procoagulant or esterolytic functions showed a similar optimum activity, but complexes of prothrombin or alpha-thrombin with either antithrombin III or hirudin did not. These findings indicate that the regions in thrombin responsible for monocyte chemotaxis are proximate to those involved in certain protein recognition interactions of alpha-thrombin (for example, hirudin binding) but are distinct from the catalytic site and from certain exosites required for clotting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bar-Shavit, R -- Kahn, A -- Wilner, G D -- Fenton, J W 2nd -- DE-04629/DE/NIDCR NIH HHS/ -- HL-13160/HL/NHLBI NIH HHS/ -- HL-14147/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 May 13;220(4598):728-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836310" target="_blank"〉PubMed〈/a〉

    Human aging: usual and successful (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1987-07-10
    Beschreibung: Research in aging has emphasized average age-related losses and neglected the substantial heterogeneity of older persons. The effects of the aging process itself have been exaggerated, and the modifying effects of diet, exercise, personal habits, and psychosocial factors underestimated. Within the category of normal aging, a distinction can be made between usual aging, in which extrinsic factors heighten the effects of aging alone, and successful aging, in which extrinsic factors play a neutral or positive role. Research on the risks associated with usual aging and strategies to modify them should help elucidate how a transition from usual to successful aging can be facilitated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowe, J W -- Kahn, R L -- New York, N.Y. -- Science. 1987 Jul 10;237(4811):143-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3299702" target="_blank"〉PubMed〈/a〉

    A multi-wavelength study of the long-period AM Her system E2003+225. I - The soft X-ray light curve and overall energy spectrum (1986)
    In:  Other Sources
    Details
    Publikationsdatum: 2011-08-19
    Beschreibung: X-ray, UV and optical data are presented of the longest period AM Her object, E2003+225, from October 12, 1983, together with a new linear polarization ephemeris. The optical and X-ray data were obtained simultaneously and the UV observations were carried out on the same day. A 6-hr observation with the Exosat 500 line/mm objective grating restricts soft X-ray blackbody temperatures to the range 18-29 eV. The blackbody luminosity exceeds the hard X-ray luminosity by at least a factor of 4.5, but is of the same order as the optical/UV component. Soft (0.1-0.25 keV) and hard X-ray (1-6 keV) light curves covering almost two orbital periods are presented and discussed.

    Long-term temporal variability of Cygnus X-2 (1988)
    In:  Other Sources
    Details
    Publikationsdatum: 2011-08-19
    Beschreibung: Observations of the low-mass binary X-ray source Cyg X-2 taken over a five-year period using instruments on OSO 8, HEAO 1, and Einstein are presented. Irregular changes in intensity of up to 60 percent on time scales ranging from minutes to days are seen. The source appears to have long-term low-luminosity states during which dips lasting about three days occur. When these long dips occur, they always appear at the same phase in the optically determined 9.8-day orbital period. There are three distinct types of short-term dips distinguished by differing correlations between spectral hardness and intensity.

    X-ray spectroscopy of the ultrasoft transient 4U 1543 - 47 (1989)
    In:  Other Sources
    Details
    Publikationsdatum: 2011-08-19
    Beschreibung: The X-ray transient 4U 1543 - 47 was observed in August 1983 by the Exosat observatory near the maximum of an outburst. The X-ray spectrum was measured using a gas scintillation proportional counter (GSPC) and a transmission grating spectrometer (TGS). A broad (FWHM about 2.7 keV) line at 5.9 keV is detected in the GSPC, which is interpreted as a redshifted and broadened iron K-alpha line. The line broadening and redshift may arise from either Compton scattering in a cool plasma with small optical depth and/or from Droppler and relativistic effects in the vicinity of compact object. The spectrum below 2 keV, obtained with the TGS, shows evidence for a broad emission feature at 0.74 keV, which may be an iron L-transition complex. However, such an emission feature could be an artifact caused by an anomalously low interstellar absorption by neutral oxygen. The contimuum emission is extremely soft and is well described by an unsaturated Comptonized spectrum from very cool plasma (kT = 0.84 keV) with large scattering depth.

    X-ray observations of LMC X-3 with the monitor proportional counter aboard the HEAO 2 Einstein observatory - A comparison with Cygnus X-1 (1983)
    In:  Other Sources
    Details
    Publikationsdatum: 2011-08-18
    Beschreibung: A comparison is presented of the black hole candidates LMC X-3 and Cygnus X-1 based on Einstein observations of LMC X-3 with the monitor proportional counter. A spectral analysis shows LMC X-3 to be more like the typical bright galactic X-ray source than Cygnus X-1. A search for periodic pulsations over a period range from 0.2 ms to over 1000 s set upper limits at the 90 percent confidence level of the order of 10 percent. An analysis of the aperiodic variability of LMC X-3 shows none of the shot noise behavior characteristic of Cygnus X-1. The absence of distinctive X-ray properties common to both sources suggests that the identification of black hole candidates on the basis of X-ray properties similar to Cygnus X-1 (or LMC X-3) is not reliable.
