    Effects of the obese gene product on body weight regulation in ob/ob mice (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-28
    Description: C57BL/6J mice with a mutation in the obese (ob) gene are obese, diabetic, and exhibit reduced activity, metabolism, and body temperature. Daily intraperitoneal injection of these mice with recombinant OB protein lowered their body weight, percent body fat, food intake, and serum concentrations of glucose and insulin. In addition, metabolic rate, body temperature, and activity levels were increased by this treatment. None of these parameters was altered beyond the level observed in lean controls, suggesting that the OB protein normalized the metabolic status of the ob/ob mice. Lean animals injected with OB protein maintained a smaller weight loss throughout the 28-day study and showed no changes in any of the metabolic parameters. These data suggest that the OB protein regulates body weight and fat deposition through effects on metabolism and appetite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pelleymounter, M A -- Cullen, M J -- Baker, M B -- Hecht, R -- Winters, D -- Boone, T -- Collins, F -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):540-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Amgen, Inc., Thousand Oaks, CA 91320, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624776" target="_blank"〉PubMed〈/a〉

    Inferring Selected Cloud Properties from Satellite Lightning Data (1999)
    In:  CASI
    Details
    Publication Date: 2019-07-10
    Description: The recent advent of satellite lightning detection programs has introduced a new potential for obtaining global information about other (hard to measure) cloud properties. We have made use of observations together with numerical model studies to show that positive correlations exist between: (1) lightning flashrate (F) and vertical velocity (w); and (2) flashrate (F) and the amount of condensate (water and ice) lofted through the -10 C isotherm (C(sub u)). The lightning flashrate appears to be very sensitive to the magnitude of the updraft velocity, with F increasing rapidly with w above a threshold of w approx. = 5-10 m/s. By contrast, we have found that the flashrate/condensate relationship appears to be approximately linear. We are currently refining the F-updraft and F-condensate relationships with further model studies before applying them to lightning data from the Optical Transient Detector (OTD) and the Lightning Imaging Sensor (LIS). We hope, with this method, to provide estimates of the large scale vertical water transport by continental convective systems over seasonal timescales.
