    Microwaves: effect on thermoregulatory behavior in rats (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-07
    Description: Rats, with their fur clipped, pressed a lever to turn on an infrared lamp while in a cold chamber. When they were exposed to continuous-wave microwaves at 2450 megahertz for 15-minute periods, the rate at which they turned on the infrared lamp decreased as a function of the microwave power density, which ranged between 5 and 20 milliwatts per square centimeter. This result indicates that behaviorally significant levels of heating may occur at an exposure duration and intensities that do not produce measurable changes in many other behavioral measures or in colonic temperature. Further study of how microwaves affect thermoregulatory behavior may help us understand such phenomena as the reported "nonthermal" behavioral effects of microwaves.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stern, S -- Margolin, L -- Weiss, B -- Lu, S T -- Michaelson, S M -- New York, N.Y. -- Science. 1979 Dec 7;206(4423):1198-201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/505008" target="_blank"〉PubMed〈/a〉

    An about 50,000-dalton protein in adrenal medulla: a common precursor of [Met]- and [Leu]enkephalin (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-06-27
    Description: A protein that may be an enkephalin precursor has been identified in extracts of bovine adrenal medulla. This protein (about 50,000 daltons) appears to contain seven copies of [Met]enkephalin and one copy of [Leu]enkephalin. Digestion with trypsin and carboxypeptidase B yields [Met]enkephalin and [Leu]enkephalin in a ratio of almost 7 to 1. The enkephalins were identified by chromatography and by their binding to opiate receptors. Some characteristics of several other adrenal peptides that may serve as intermediates in the biosynthesis of the enkephalins are presented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lewis, R V -- Stern, A S -- Kimura, S -- Rossier, J -- Stein, S -- Udenfriend, S -- New York, N.Y. -- Science. 1980 Jun 27;208(4451):1459-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7384787" target="_blank"〉PubMed〈/a〉
