    Description: Human T-cell leukemia virus (HTLV) is a human type-C RNA tumor virus (retrovirus) previously identified in and isolated from several patients with T-cell leukemias or lymphomas. The known virus isolates from the United States and Japan are closely related and are found in adults with an acute malignancy of mature T cells. A related retrovirus has been found in a patient (Mo) with a somewhat different disease (a T-cell variant of relatively benign hairy cell leukemia). Serum from Mo contains antibodies to the major internal core protein (p24) of HTLV. A T-cell line established from the spleen of Mo expresses HTLV antigens. However, HTLV from Mo is significantly different from all previous HTLV isolates in immunological cross-reactivity tests of p24. The usual prototype HTLV isolate is represented as HTLV-I, and the HTLV from Mo is represented as HTLV-II. Individual members of each subgroup may then be identified by subscript initials of the patient [for example, HTLV-I(CR), HTLV-I(MB), and HTLV-II(Mo)].〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kalyanaraman, V S -- Sarngadharan, M G -- Robert-Guroff, M -- Miyoshi, I -- Golde, D -- Gallo, R C -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):571-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981847" target="_blank"〉PubMed〈/a〉

    Description: Specific consistent chromosome translocations are regularly observed in certain human leukemias and lymphomas. For the myeloid leukemias, the constant recombinants are: the long arm of 9 to chromosome 22 in chronic myeloid leukemia, the long arm of 21 to chromosome 8 in acute myeloblastic leukemia, and the long arm of 17 to chromosome 15 in acute promyelocytic leukemia. Three related translocations are seen in Burkitt lymphoma and B cell acute lymphocytic leukemia; in each one, chromosome 8 is involved with chromosome 2, 14, or 22. Analysis of a complex translocation affecting chromosomes 8 and 14 indicates that the translocation of chromosome 8 to chromosome 14 is the critical constant rearrangement. The analysis of the DNA at the translocation sites of these chromosomes, rather than the reciprocal of each translocation, appears to be the most productive focus for initial study. The various immunoglobulin loci are located in chromosomes 2, 14, and 22, the chromosomes regularly involved in translocations in Burkitt lymphoma and B cell acute lymphocytic leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowley, J D -- CA 16910/CA/NCI NIH HHS/ -- CA 19266/CA/NCI NIH HHS/ -- CA 25568/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 May 14;216(4547):749-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079737" target="_blank"〉PubMed〈/a〉

    Description: Increment-threshold spectral sensitivity functions were determined during the dominance and suppression phases of binocular rivalry. The shapes of the functions obtained during the dominance phase exhibited three maxima at approximately 440, 530, and 610 nanometers and resembled functions obtained for nonrivalrous control conditions. However, the functions measured during suppression had a single broad peak near 555 nanometers and were adequately described by functions measured with flicker methods during nonrivalrous conditions. The results indicate that binocular rivalry differentially attenuates opponent-color information relative to achromatic information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, E L -- Levi, D M -- Harwerth, R S -- White, J M -- EY01139/EY/NEI NIH HHS/ -- EY01728/EY/NEI NIH HHS/ -- EY03611/EY/NEI NIH HHS/ -- R01 EY001139/EY/NEI NIH HHS/ -- R01 EY003611/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 19;218(4574):802-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134975" target="_blank"〉PubMed〈/a〉

    Description: Although several studies of Alzheimer's disease suggest that the frequency of neuritic plaques in the cerebral cortex is correlated with the severity of dementia and with reduction in presynaptic cholinergic markers in the cortex, the relationship between cholinergic cortical innervation and the pathogenesis of plaques is unknown. The hypothesis was tested that the neurites in the plaque consist, in part, of presynaptic cholinergic axons, many of which arise from neurons in the basal forebrain. This hypothesis was tested by analyzing the character and distribution of plaques in monkeys, aged 4 to 31 years, with staining for acetylcholin-esterase and also with Congo red and silver stains. Immature and mature plaques were rich in acetylcholinesterase. As the plaques matured, the amount of amyloid increased, and the number of neurites and the activity of acetylcholinesterase decreased. End-stage amyloid-rich plaques lacked acetylcholinesterase. These observations indicate that changes in cortical cholinergic innervation are an important feature in the pathogenesis and evolution of the neuritic plaque.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Struble, R G -- Cork, L C -- Whitehouse, P J -- Price, D L -- NS 07179/NS/NINDS NIH HHS/ -- NS 10580/NS/NINDS NIH HHS/ -- NS 15721/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Apr 23;216(4544):413-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6803359" target="_blank"〉PubMed〈/a〉

    Description: By the close of this century the world may have to feed as many as 2 billion additional people. Most of them will be born in developing countries, especially in marginal lands ill-suited for food production. This article focuses on efforts by the International Agricultural Research Centers to increase food production in the Third World and addresses the social and ecological issues raised by the introduction of high-yielding varieties into fertile Third World lands and describe how varieties are being tailored for introduction into marginal areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Plucknett, D L -- Smith, N J -- New York, N.Y. -- Science. 1982 Jul 16;217(4556):215-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089555" target="_blank"〉PubMed〈/a〉

    Description: Contrary to a previous assumption, the center of the expanding pattern of visual flow is not generally useful as an aid in judging the direction of self motion since its direction depends on the direction of gaze. For some visual environments, however, the point of maximum rate of change of magnification in the retinal image coincides with the direction of self motion, independently of the direction of gaze. This visual indicator could be used to judge the direction of self motion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regan, D -- Beverley, K I -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):194-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053572" target="_blank"〉PubMed〈/a〉

    Description: Recent evidence indicates that the nucleus basalis of Meynert, a distinct population of basal forebrain neurons, is a major source of cholinergic innervation of the cerebral cortex. Postmortem studies have previously demonstrated profound reduction in the presynaptic markers for cholinergic neurons in the cortex of patients with Alzheimer's disease and senile dementia of the Alzheimer's type. The results of this study show that neurons of the nucleus basalis of Meynert undergo a profound (greater than 75 percent) and selective degeneration in these patients and provide a pathological substrate of the cholinergic deficiency in their brains. Demonstration of selective degeneration of such neurons represents the first documentation of a loss of a transmitter-specific neuronal population in a major disorder of higher cortical function and, as such, points to a critical subcortical lesion in Alzheimer's patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitehouse, P J -- Price, D L -- Struble, R G -- Clark, A W -- Coyle, J T -- Delon, M R -- MH 00125/MH/NIMH NIH HHS/ -- MH 26654/MH/NIMH NIH HHS/ -- NS 10580/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1237-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058341" target="_blank"〉PubMed〈/a〉

    Description: Prompt and long-term closure of full-thickness skin wounds is guinea pigs and humans is achieved by applying a bilayer polymeric membrane. The membrane comprises a top layer of a silicone elastomer and a bottom layer of a porous cross-linked network of collagen and glycosaminoglycan. The bottom layer can be seeded with a small number of autologous basal cells before grafting. No immunosuppression is used and infection, exudation, and rejection are absent. Host tissue utilizes the sterile membrane as a culture medium to synthesize neoepidermal and neodermal tissue. A functional extension of skin over the entire wound area is formed in about 4 weeks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yannas, I V -- Burke, J F -- Orgill, D P -- Skrabut, E M -- GM 21700/GM/NIGMS NIH HHS/ -- GM 23946/GM/NIGMS NIH HHS/ -- HL 14322/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):174-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7031899" target="_blank"〉PubMed〈/a〉
