    Description: WIN 51711 and WIN 52084 are structurally related, antiviral compounds that inhibit the replication of rhino (common cold) viruses and related picornaviruses. They prevent the pH-mediated uncoating of the viral RNA. The compounds consist of a 3-methylisoxazole group that inserts itself into the hydrophobic interior of the VP1 beta-barrel, a connecting seven-membered aliphatic chain, and a 4-oxazolinylphenoxy group (OP) that covers the entrance to an ion channel in the floor of the "canyon." Viral disassembly may be inhibited by preventing the collapse of the VP1 hydrophobic pocket or by blocking the flow of ions into the virus interior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, T J -- Kremer, M J -- Luo, M -- Vriend, G -- Arnold, E -- Kamer, G -- Rossmann, M G -- McKinlay, M A -- Diana, G D -- Otto, M J -- New York, N.Y. -- Science. 1986 Sep 19;233(4770):1286-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3018924" target="_blank"〉PubMed〈/a〉

    Description: When the human T-cell line A3.01 is infected with HTLV-III/LAV, the virus associated with the acquired immune deficiency syndrome (AIDS), most of the cells are killed. However, a small number of cells that lack the Leu-3 surface marker survive. Under normal conditions these surviving cells do not produce virus, nor can they be infected by the virus, but they can be induced to produce virus by treatment with 5-iodo-2'-deoxyuridine. This response can be induced for as long as 3 months after the initial infection, suggesting that the cells may harbor a latent form of HTLV-III/LAV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Folks, T -- Powell, D M -- Lightfoote, M M -- Benn, S -- Martin, M A -- Fauci, A S -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):600-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003906" target="_blank"〉PubMed〈/a〉

    Description: One of the common neurological complications in patients with the acquired immune deficiency syndrome (AIDS) is a subacute encephalopathy with progressive dementia. By using the techniques of cocultivation for virus isolation, in situ hybridization, immunocytochemistry, and transmission electron microscopy, the identity of an important cell type that supports replication of the AIDS retrovirus in brain tissue was determined in two affected individuals. These cells were mononucleated and multinucleated macrophages that actively synthesized viral RNA and produced progeny virions in the brains of the patients. Infected brain macrophages may serve as a reservoir for virus and as a vehicle for viral dissemination in the infected host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koenig, S -- Gendelman, H E -- Orenstein, J M -- Dal Canto, M C -- Pezeshkpour, G H -- Yungbluth, M -- Janotta, F -- Aksamit, A -- Martin, M A -- Fauci, A S -- New York, N.Y. -- Science. 1986 Sep 5;233(4768):1089-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3016903" target="_blank"〉PubMed〈/a〉

    Description: The Wind River Mountains are a NW-SE trending range composed almost entirely of high-grade Archean gneiss and granites which were thrust to the west over Phanerozoic sediments during the Laramide orogeny. Late Archean granites make up over 50% of the exposed crust and dominates the southern half of the range, while older orthogneisses and magnatites form most of the northen half of the range. Locally these gneisses contain enclaves of supracrustal rocks, which appear to be the oldest preserved rocks in the range. Detailed work in the Medina Mountain area of the central Wind River Mountains and reconnaissance work throughout much of the northern part of the range has allowed definition of the sequence of events which marked crustal development in this area. The sequence of events are described.

    Description: Gene probes for interferons alpha and beta 1 and v-ets were hybridized to metaphase chromosomes from three patients with acute monocytic leukemia who had a chromosomal translocation, t(9;11)(p22;q23). The break in the short arm of chromosome 9 split the interferon genes, and the interferon-beta 1 gene was translocated to chromosome 11. The c-ets-1 gene was translocated from chromosome 11 to the short arm of chromosome 9 adjacent to the interferon genes. No DNA rearrangement was observed when these probes were hybridized to genomic DNA from leukemic cells of two of the patients. The results suggest that the juxtaposition of the interferon and c-ets-1 genes may be involved in the pathogenesis of human monocytic leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diaz, M O -- Le Beau, M M -- Pitha, P -- Rowley, J D -- CA 16910/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 17;231(4735):265-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3455787" target="_blank"〉PubMed〈/a〉

    Description: By in situ chromosomal hybridization, the GM-CSF and FMS genes were localized to human chromosome 5 at bands q23 to q31, and at band 5q33, respectively. These genes encode proteins involved in the regulation of hematopoiesis, and are located within a chromosome region frequently deleted in patients with neoplastic myeloid disorders. Both genes were deleted in the 5q-chromosome from bone marrow cells of two patients with refractory anemia and a del(5)(q15q33.3). The GM-CSF gene alone was deleted in a third patient with acute nonlymphocytic leukemia (ANLL) who has a smaller deletion, del(5)(q22q33.1). Leukemia cells from a fourth patient who has ANLL and does not have a del(5q), but who has a rearranged chromosome 5 that is missing bands q31.3 to q33.1 [ins(21;5)(q22;q31.3q33.1)] were used to sublocalize these genes; both genes were present on the rearranged chromosome 5. Thus, the deletion of one or both of these genes may be important in the pathogenesis of myelodysplastic syndromes or of ANLL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Le Beau, M M -- Westbrook, C A -- Diaz, M O -- Larson, R A -- Rowley, J D -- Gasson, J C -- Golde, D W -- Sherr, C J -- CA 16910/CA/NCI NIH HHS/ -- CA 23954/CA/NCI NIH HHS/ -- CA 30388/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):984-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3484837" target="_blank"〉PubMed〈/a〉

    Description: The incidence of the acquired immune deficiency syndrome (AIDS) among persons infected with human T-lymphotropic virus type III (HTLV-III) was evaluated prospectively among 725 persons who were at high risk of AIDS and had enrolled before October 1982 in cohort studies of homosexual men, parenteral drug users, and hemophiliacs. A total of 276 (38.1 percent) of the subjects were either HTLV-III seropositive at enrollment or developed HTLV-III antibodies subsequently. AIDS had developed in 28 (10.1 percent) of the seropositive subjects before August 1985. By actuarial survival calculations, the 3-year incidence of AIDS among all HTLV-III seropositive subjects was 34.2 percent in the cohort of homosexual men in Manhattan, New York, and 14.9 percent (range 8.0 to 17.2 percent) in the four other cohorts. Out of 117 subjects followed for a mean of 31 months after documented seroconversion, five (all hemophiliacs) developed AIDS 28 to 62 months after the estimated date of seroconversion, supporting the hypothesis that there is a long latency between acquisition of viral infection and the development of clinical AIDS. This long latency could account for the significantly higher AIDS incidence in the New York cohort compared with other cohorts if the virus entered the New York homosexual population before it entered the populations from which the other cohorts were drawn. However, risk of AIDS development in different populations may also depend on the presence of as yet unidentified cofactors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goedert, J J -- Biggar, R J -- Weiss, S H -- Eyster, M E -- Melbye, M -- Wilson, S -- Ginzburg, H M -- Grossman, R J -- DiGioia, R A -- Sanchez, W C -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):992-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003917" target="_blank"〉PubMed〈/a〉

    Description: Cells with properties characteristic of mononuclear phagocytes were evaluated for infectivity with five different isolates of the AIDS virus, HTLV-III/LAV. Mononuclear phagocytes cultured from brain and lung tissues of AIDS patients harbored the virus. In vitro-infected macrophages from the peripheral blood, bone marrow, or cord blood of healthy donors produced large quantities of virus. Virus production persisted for at least 40 days and was not dependent on host cell proliferation. Giant multinucleated cells were frequently observed in the macrophage cultures and numerous virus particles, often located within vacuole-like structures, were present in infected cells. The different virus isolates were compared for their ability to infect macrophages and T cells. Isolates from lung- and brain-derived macrophages had a significantly higher ability to infect macrophages than T cells. In contrast, the prototype HTLV-III beta showed a 10,000-fold lower ability to infect macrophages than T cells and virus production was one-tenth that in macrophage cultures infected with other isolates, indicating that a particular variant of HTLV-III/LAV may have a preferential tropism for macrophages or T cells. These results suggest that mononuclear phagocytes may serve as primary targets for infection and agents for virus dissemination and that these virus-infected cells may play a role in the pathogenesis of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gartner, S -- Markovits, P -- Markovitz, D M -- Kaplan, M H -- Gallo, R C -- Popovic, M -- New York, N.Y. -- Science. 1986 Jul 11;233(4760):215-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014648" target="_blank"〉PubMed〈/a〉

    Description: Ivermectin, given to onchocerciasis patients as a single oral dose of 200 micrograms per kilogram of body weight, substantially reduced the uptake of Onchocerca volvulus microfilariae by Simulium yahense, an efficient black fly vector of the parasite in the tropical rain forests of West Africa. Three months after treatment, patients given ivermectin infected flies at a significantly lower rate than those who had received diethylcarbamazine or placebo, thereby reducing the number of developing larvae in the vector population. This diminished rate of infectiousness was also evident 6 months after treatment. These results strongly suggest that ivermectin could be effective in interrupting transmission of Onchocerca volvulus for epidemiologically important periods of time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cupp, E W -- Bernardo, M J -- Kiszewski, A E -- Collins, R C -- Taylor, H R -- Aziz, M A -- Greene, B M -- New York, N.Y. -- Science. 1986 Feb 14;231(4739):740-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3753801" target="_blank"〉PubMed〈/a〉
