    Description: Virus-specific CD4+ T helper lymphocytes are critical to the maintenance of effective immunity in a number of chronic viral infections, but are characteristically undetectable in chronic human immunodeficiency virus-type 1 (HIV-1) infection. In individuals who control viremia in the absence of antiviral therapy, polyclonal, persistent, and vigorous HIV-1-specific CD4+ T cell proliferative responses were present, resulting in the elaboration of interferon-gamma and antiviral beta chemokines. In persons with chronic infection, HIV-1-specific proliferative responses to p24 were inversely related to viral load. Strong HIV-1-specific proliferative responses were also detected following treatment of acutely infected persons with potent antiviral therapy. The HIV-1-specific helper cells are likely to be important in immunotherapeutic interventions and vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, E S -- Billingsley, J M -- Caliendo, A M -- Boswell, S L -- Sax, P E -- Kalams, S A -- Walker, B D -- F32-AI09738/AI/NIAID NIH HHS/ -- R01-A136550/PHS HHS/ -- R01-AI28568/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Nov 21;278(5342):1447-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Partners AIDS Research Center and Infectious Disease Unit, Massachusetts General Hospital, and Harvard Medical School, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9367954" target="_blank"〉PubMed〈/a〉

    Description: Members of the recently recognized SRC-1 family of transcriptional coactivators interact with steroid hormone receptors to enhance ligand-dependent transcription. AIB1, a member of the SRC-1 family, was cloned during a search on the long arm of chromosome 20 for genes whose expression and copy number were elevated in human breast cancers. AIB1 amplification and overexpression were observed in four of five estrogen receptor-positive breast and ovarian cancer cell lines. Subsequent evaluation of 105 unselected specimens of primary breast cancer found AIB1 amplification in approximately 10 percent and high expression in 64 percent of the primary tumors analyzed. AIB1 protein interacted with estrogen receptors in a ligand-dependent fashion, and transfection of AIB1 resulted in enhancement of estrogen-dependent transcription. These observations identify AIB1 as a nuclear receptor coactivator whose altered expression may contribute to development of steroid-dependent cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anzick, S L -- Kononen, J -- Walker, R L -- Azorsa, D O -- Tanner, M M -- Guan, X Y -- Sauter, G -- Kallioniemi, O P -- Trent, J M -- Meltzer, P S -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):965-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cancer Genetics, National Human Genome Research Institute, National Institutes of Health, Bethesda, MD, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252329" target="_blank"〉PubMed〈/a〉

    Description: Despite its high prevalence, very little is known regarding genetic predisposition to prostate cancer. A genome-wide scan performed in 66 high-risk prostate cancer families has provided evidence of linkage to the long arm of chromosome 1 (1q24-25). Analysis of an additional set of 25 North American and Swedish families with markers in this region resulted in significant evidence of linkage in the combined set of 91 families. The data provide strong evidence of a major prostate cancer susceptibility locus on chromosome 1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, J R -- Freije, D -- Carpten, J D -- Gronberg, H -- Xu, J -- Isaacs, S D -- Brownstein, M J -- Bova, G S -- Guo, H -- Bujnovszky, P -- Nusskern, D R -- Damber, J E -- Bergh, A -- Emanuelsson, M -- Kallioniemi, O P -- Walker-Daniels, J -- Bailey-Wilson, J E -- Beaty, T H -- Meyers, D A -- Walsh, P C -- Collins, F S -- Trent, J M -- Isaacs, W B -- CA58236/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 Nov 22;274(5291):1371-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Human Genome Research, National Institutes of Health, Bethesda, MD, USA. jtrent@nchgr.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8910276" target="_blank"〉PubMed〈/a〉

    Description: Electrical subcutaneous nerve stimulation of radial, median, and saphenous nerves has been shown to produce prolonged analgesia. In a double blind study, such stimulation also suppressed clonus for 3 hours after stimulation ceased in subjects with spasticity. Since the effect is contralateral, each subject was his own control. Because stimulation of the nerve in the wrist suppressed ankle clonus, the mechanism mediating the effect must be centrifugal inhibition. These results suggest that subcutaneous nerve stimulation may also be a tool in the management of spasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, J B -- New York, N.Y. -- Science. 1982 Apr 9;216(4542):203-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063882" target="_blank"〉PubMed〈/a〉

    Description: Models of the magnetospheric and magnetosheath magnetic fields are used to determine the relative orientations of the two near the dayside magnetopause for the purpose of locating potential merging sites. Areas of the magnetopause with various degrees of antiparallelness for different Interplanetary fields as contour diagrams are studied. For southward and GSE-Y interplanetary field, the patterns obtained are consistent with those envisioned by Crooker in an earlier analysis which used simplified representations for the magnetic field geometry. Here the application of realistic models shows the locations of areas where any antiparallel component occurs. Merging sites for radial interplanetary fields are also illustrated. The results suggest that the geometrical configuration of the fields is suitable for merging over a large fraction of the magnetopause for interplanetary fields that are either primarily southward, GSE-Y, or radial (GSE-X) in direction.

    Description: An array of 5 autonomous spectrometers, the imaging spectrometric observatory covers a broad wavelength range (approximately 200 to 12,000 A), has a resolution selectable down to approximately 0.5 A, and a dynamic range of approximately 10 to the 7th power and is designed to select experiment measurement sequences by software control. Because current models of thermospheric ionic processes produce too much N2(+) ionization, the N2(+) reaction with O and the chemistry of metastable (N(+) ions and of O2(+) ions are objects of study on Spacelab 1.

    Description: The interaction of the solar wind with the earth's magnetosphere during a northward interplanetary magnetic field was studied by using a three-dimensional magneto-hydrodynamic model. For a northward interplanetary magnetic field on 5 nT, the plasma sheet thickens near the noon-midnight meridian plane. When projected onto the polar cap this appears as a narrow channel extending from midnight towards noon. This plasma pattern is associated with three pairs of convection cells. The high latitude sunward convection and northern B(z) Birkeland current are caused by magnetic merging in the polar region.

    Description: Recent advances in the development of models of the macroscopic properties of the terrestrial and planetary magnetospheres are reviewed. Particular attention is given to work on semiempirical models of magnetic and electric fields in the earth's magnetosphere, the modeling of magnetospheric storms and substorms in the inner magnetosphere, and the self-consistent modeling of processes in the magnetotail, including reconnection. Magnetohydrodynamic models of the dayside magnetosphere and the magnetotail which are based on calculations of the interaction of the solar wind with the magnetosphere are also considered. Finally, work on the modeling of the magnetospheres of Mercury, Venus, Jupiter, Saturn and Uranus is presented.
