    Description: The density but not the affinity of beta-adrenergic receptors declined significantly with age in rat pineal gland, corpus striatum, and cerebellum, as determined by the binding of tritiated dihydroalprenolol. Exposing rats to light for 12 hours increased the binding of this radioligand in 3-month-old but not in 24-month-old rats. The reduced responsiveness to catecholamines seen in aging may be due to a decrease in the number of beta-adrenergic receptors which, in turn, may be caused by an impaired capacity of receptors in aged animals to adapt to changes in adrenergic neuronal input.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenberg, L H -- Weiss, B -- New York, N.Y. -- Science. 1978 Jul 7;201(4350):61-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/208145" target="_blank"〉PubMed〈/a〉

    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〉

    Description: The global burden of neurological, neuropsychiatric, substance-use and neurodevelopmental disorders in low- and middle-income countries is worsened, not only by the lack of targeted research funding, but also by the lack of relevant in-country research capacity. Such capacity, from the individual to the national level, is necessary to address the problems within a local context. As for many health issues in these countries, the ability to address this burden requires development of research infrastructure and a trained cadre of clinicians and scientists who can ask the right questions, and conduct, manage, apply and disseminate research for practice and policy. This Review describes some of the evolving issues, knowledge and programmes focused on building research capacity in low- and middle-income countries in general and for brain and nervous system disorders in particular.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cottler, Linda B -- Zunt, Joseph -- Weiss, Bahr -- Kamal, Ayeesha Kamran -- Vaddiparti, Krishna -- D43 TW009120/TW/FIC NIH HHS/ -- D43TW008660/TW/FIC NIH HHS/ -- D43TW009089/TW/FIC NIH HHS/ -- D43TW009120/TW/FIC NIH HHS/ -- England -- Nature. 2015 Nov 19;527(7578):S207-13. doi: 10.1038/nature16037.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Epidemiology, College of Public Health and Health Professions and College of Medicine, University of Florida, Gainesville, Florida, USA. ; Department of Neurology, University of Washington, Seattle, Washington, USA. ; Department of Psychology and Human Development, Vanderbilt University, Nashville, Tennnesse, USA. ; Stroke Service, Section of Neurology, Department of Medicine, The International Cerebrovascular Translational Clinical Research Training Program (Fogarty International Center, NIH) Aga Khan University, Karachi, Pakistan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26580329" target="_blank"〉PubMed〈/a〉
