    Description: Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious stimuli, without changing the perceived intensity. Positron emission tomography revealed significant changes in pain-evoked activity within anterior cingulate cortex, consistent with the encoding of perceived unpleasantness, whereas primary somatosensory cortex activation was unaltered. These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainville, P -- Duncan, G H -- Price, D D -- Carrier, B -- Bushnell, M C -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉D-epartement de Psychologie and Centre de Recherche en Sciences Neurologiques, Universite de Montreal, Montreal, Quebec, Canada H3C 3J7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252330" target="_blank"〉PubMed〈/a〉

    Description: The participation of medial temporal-lobe structures in memory performance was examined by functional magnetic resonance imaging of local blood oxygenation level-dependent signals. Signals were measured during encoding into memory complex scenes or line drawings and during retrieval from memory of previously studied line drawings or words. Encoding tasks yielded increased signals for unfamiliar information in a posterior medial-temporal region that were focused in the parahippocampal cortex. Retrieval tasks yielded increased signals for successfully remembered information in an anterior medial-temporal region that were focused in the subiculum. These results indicate that separate components of the human medial temporal-lobe memory system are active during distinct memory processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabrieli, J D -- Brewer, J B -- Desmond, J E -- Glover, G H -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):264-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology and Neuroscience Program, Stanford University, Stanford, CA 94305, USA. gabrieli@psych.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9092477" target="_blank"〉PubMed〈/a〉

    Description: Lavie's theory of attention proposes that the processing load in a relevant task determines the extent to which irrelevant distractors are processed. This theory was tested by asking participants in a study to perform linguistic tasks of low or high load while ignoring irrelevant visual motion in the periphery of the display. Although task and distractor were unrelated, both functional imaging of motion-related activity in cortical area V5 and psychophysical measures of the motion aftereffect showed reduced motion processing during high load in the linguistic task. These findings fulfill the prediction that perception of irrelevant distractors depends on the relevant processing load.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rees, G -- Frith, C D -- Lavie, N -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1616-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London WC1N 3BG, UK. g.rees@fil.ion.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374459" target="_blank"〉PubMed〈/a〉

    Description: A systematic search of the nonrecombining region of the human Y chromosome (NRY) identified 12 novel genes or families, 10 with full-length complementary DNA sequences. All 12 genes, and six of eight NRY genes or families previously isolated by less systematic means, fell into two classes. Genes in the first group were expressed in many organs; these housekeeping genes have X homologs that escape X inactivation. The second group, consisting of Y-chromosomal gene families expressed specifically in testes, may account for infertility among men with Y deletions. The coherence of the NRY's gene content contrasts with the apparently haphazard content of most eukaryotic chromosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lahn, B T -- Page, D C -- New York, N.Y. -- Science. 1997 Oct 24;278(5338):675-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Whitehead Institute, and Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9381176" target="_blank"〉PubMed〈/a〉

    Description: In lymphoid tissue, where human immunodeficiency virus-type 1 (HIV-1) is produced and stored, three-drug treatment with viral protease and reverse transcriptase inhibitors markedly reduced viral burden. This was shown by in situ hybridization and computerized quantitative analysis of serial tonsil biopsies from previously untreated adults. The frequency of productive mononuclear cells (MNCs) initially diminished with a half-life of about 1 day. Surprisingly, the amount of HIV-1 RNA in virus trapped on follicular dendritic cells (FDCs) decreased almost as quickly. After 24 weeks, MNCs with very few copies of HIV-1 RNA per cell were still detectable, as was proviral DNA; however, the amount of FDC-associated virus decreased by 〉/=3.4 log units. Thus, 6 months of potent therapy controlled active replication and cleared 〉99.9 percent of virus from the secondary lymphoid tissue reservoir.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cavert, W -- Notermans, D W -- Staskus, K -- Wietgrefe, S W -- Zupancic, M -- Gebhard, K -- Henry, K -- Zhang, Z Q -- Mills, R -- McDade, H -- Schuwirth, C M -- Goudsmit, J -- Danner, S A -- Haase, A T -- AI 25017/AI/NIAID NIH HHS/ -- AI 28246/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 May 9;276(5314):960-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Minnesota Medical School, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9139661" target="_blank"〉PubMed〈/a〉

    Description: Global anterograde amnesia is described in three patients with brain injuries that occurred in one case at birth, in another by age 4, and in the third at age 9. Magnetic resonance techniques revealed bilateral hippocampal pathology in all three cases. Remarkably, despite their pronounced amnesia for the episodes of everyday life, all three patients attended mainstream schools and attained levels of speech and language competence, literacy, and factual knowledge that are within the low average to average range. The findings provide support for the view that the episodic and semantic components of cognitive memory are partly dissociable, with only the episodic component being fully dependent on the hippocampus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vargha-Khadem, F -- Gadian, D G -- Watkins, K E -- Connelly, A -- Van Paesschen, W -- Mishkin, M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):376-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cognitive Neuroscience Unit, Institute of Child Health, University College London Medical School, Wolfson Centre, Mecklenburgh Square, London WC1N 2AP, UK. fkhadem@ich.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219696" target="_blank"〉PubMed〈/a〉

    Description: Highly active antiretroviral therapy (HAART) increases CD4(+) cell numbers, but its ability to correct the human immunodeficiency virus (HIV)-induced immune deficiency remains unknown. A three-phase T cell reconstitution was demonstrated after HAART, with: (i) an early rise of memory CD4(+) cells, (ii) a reduction in T cell activation correlated to the decreasing retroviral activity together with an improved CD4(+) T cell reactivity to recall antigens, and (iii) a late rise of "naive" CD4(+) lymphocytes while CD8(+) T cells declined, however, without complete normalization of these parameters. Thus, decreasing the HIV load can reverse HIV-driven activation and CD4(+) T cell defects in advanced HIV-infected patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Autran, B -- Carcelain, G -- Li, T S -- Blanc, C -- Mathez, D -- Tubiana, R -- Katlama, C -- Debre, P -- Leibowitch, J -- New York, N.Y. -- Science. 1997 Jul 4;277(5322):112-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Immunologie Cellulaire, URA CNRS 625, Hopital Pitie-Salpetriere, 47-83 Boulevard de l'Hopital, Paris, France. autran@psl.ap-hop-paris.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9204894" target="_blank"〉PubMed〈/a〉
