    Description: A sensitive radioimmunoassay for atrial natriuretic peptide was used to examine the relation between circulating atrial natriuretic peptide and cardiac filling pressure in normal human subjects, in patients with cardiovascular disease and normal cardiac filling pressure, and in patients with cardiovascular disease and elevated cardiac filling pressure with and without congestive heart failure. The present studies establish a normal range for atrial natriuretic peptide in normal human subjects. These studies also establish that elevated cardiac filling pressure is associated with increased circulating concentrations of atrial natriuretic peptide and that congestive heart failure is not characterized by a deficiency in atrial natriuretic peptide, but with its elevation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnett, J C Jr -- Kao, P C -- Hu, D C -- Heser, D W -- Heublein, D -- Granger, J P -- Opgenorth, T J -- Reeder, G S -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2935937" target="_blank"〉PubMed〈/a〉

    Description: In postmortem studies of patients with schizophrenia, D2 dopamine receptors in the basal ganglia have been observed to be more numerous than in patients with no history of neurological or psychiatric disease. Because most patients with schizophrenia are treated with neuroleptic drugs that block D2 dopamine receptors in the caudate nucleus, it has been suggested that this increase in the number of receptors is a result of adaptation to these drugs rather than a biochemical abnormality intrinsic to schizophrenia. With positron emission tomography (PET), the D2 dopamine receptor density in the caudate nucleus of living human beings was measured in normal volunteers and in two groups of patients with schizophrenia--one group that had never been treated with neuroleptics and another group that had been treated with these drugs. D2 dopamine receptor densities in the caudate nucleus were higher in both groups of patients than in the normal volunteers. Thus, schizophrenia itself is associated with an increase in brain D2 dopamine receptor density.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, D F -- Wagner, H N Jr -- Tune, L E -- Dannals, R F -- Pearlson, G D -- Links, J M -- Tamminga, C A -- Broussolle, E P -- Ravert, H T -- Wilson, A A -- Toung, J K -- Malat, J -- Williams, J A -- O'Tuama, L A -- Snyder, S H -- Kuhar, M J -- Gjedde, A -- 1RO1 53146/PHS HHS/ -- NS15080/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 19;234(4783):1558-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2878495" target="_blank"〉PubMed〈/a〉

    Description: An antiserum prepared against thymosin alpha 1, a hormone secreted by the thymus gland, effectively neutralized the AIDS-associated virus [HTLV-III/LAV (clone BH-10)] and blocked its replication in H9 cells. Reverse transcriptase activity and expression of the HTLV-III/LAV antigens p15 and p24 were inhibited by purified immunoglobulin G preparations of antisera to thymosin alpha 1. The antiviral activity of the antiserum was found to be due to a region of homology between thymosin alpha 1 and p17, a product of the gag gene of HTLV-III/LAV. Comparison of the primary sequences of thymosin alpha 1 and the gag protein revealed a 44% to 50% homology in an 18-amino acid region, between positions 11 and 28 on thymosin alpha 1 and 92 and 109 on the gag protein. The effectiveness of the thymosin alpha 1 antiserum and of immunoglobulin G-enriched preparations in blocking replication of HTLV-III(BH-10) in H9 cells suggests a novel approach to the development of an AIDS vaccine. A vaccine directed against the gag protein might overcome the problem of genetic drift in the envelope region of the virus and be useful against all genetic variants of HTLV-III/LAV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sarin, P S -- Sun, D K -- Thornton, A H -- Naylor, P H -- Goldstein, A L -- CA 24974/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 May 30;232(4754):1135-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010464" target="_blank"〉PubMed〈/a〉

    Description: The etiological agent of AIDS, LAV/HTLV-III, is common in Central Africa but is not endemic in other areas of that continent. A novel human retrovirus, distinct from LAV/HTLV-III, has now been isolated from two AIDS patients from West Africa. Partial characterization of this virus revealed that it has biological and morphological properties very similar to LAV but that it differs in some of its antigenic components. Although the core antigens may share some common epitopes, the West African AIDS retrovirus and LAV differ substantially in their envelope glycoproteins. The envelope antigen of the West African virus can be recognized by serum from a macaque with simian AIDS infected by the simian retrovirus termed STLV-IIImac, suggesting that the West African AIDS virus may be more closely related to this simian virus than to LAV. Hybridization experiments with LAV subgenomic probes further established that this new retrovirus, here referred to as LAV-II, is distantly related to LAV and distinct from STLV-IIImac.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clavel, F -- Guetard, D -- Brun-Vezinet, F -- Chamaret, S -- Rey, M A -- Santos-Ferreira, M O -- Laurent, A G -- Dauguet, C -- Katlama, C -- Rouzioux, C -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):343-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2425430" target="_blank"〉PubMed〈/a〉
