    Microsatellite instability in cancer of the proximal colon (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-07
    Description: Colorectal tumor DNA was examined for somatic instability at (CA)n repeats on human chromosomes 5q, 15q, 17p, and 18q. Differences between tumor and normal DNA were detected in 25 of the 90 (28 percent) tumors examined. This instability appeared as either a substantial change in repeat length (often heterogeneous in nature) or a minor change (typically two base pairs). Microsatellite instability was significantly correlated with the tumor's location in the proximal colon (P = 0.003), with increased patient survival (P = 0.02), and, inversely, with loss of heterozygosity for chromosomes 5q, 17p, and 18q. These data suggest that some colorectal cancers may arise through a mechanism that does not necessarily involve loss of heterozygosity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thibodeau, S N -- Bren, G -- Schaid, D -- CA-15083-18E8.1/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 May 7;260(5109):816-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Laboratory, Mayo Clinic, Rochester, MN 55905.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8484122" target="_blank"〉PubMed〈/a〉

    Altered fluid transport across airway epithelium in cystic fibrosis (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-15
    Description: In cystic fibrosis (CF), absence or dysfunction of a phosphorylation-regulated chloride channel [CF transmembrane conductance regulator (CFTR)] leads to the loss or reduction of chloride secretion into the airways. Active sodium absorption is also increased in CF, and both of these ion transport changes could alter fluid transport across the airways. Under baseline conditions, cultured human airway epithelia from normal individuals absorbed fluid, and this absorption was increased in epithelia from patients with CF. In normal and CF epithelial cultures fluid absorption was inhibited by amiloride. Adenosine 3',5'-monophosphate stimulated fluid secretion in normal epithelial cultures but not in cultures from individuals with CF. In contrast, fluid secretion induced by nucleotide triphosphates (uridine triphosphate or adenosine triphosphate) was unaltered in cultures of epithelia from patients with CF, suggesting an approach to the treatment of CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, C -- Finkbeiner, W E -- Widdicombe, J H -- McCray, P B Jr -- Miller, S S -- HL 42368/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):424-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211164" target="_blank"〉PubMed〈/a〉

    MHC-restricted depletion of human myelin basic protein-reactive T cells by T cell vaccination (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-10
    Description: Activated autoreactive T cells are potentially pathogenic and regulated by clonotypic networks. Experimental autoimmune diseases can be treated by inoculation with autoreactive T cells (T cell vaccination). In the present study, patients with multiple sclerosis were inoculated with irradiated myelin basic protein (MBP)-reactive T cells. T cell responses to the inoculates were induced to deplete circulating MBP-reactive T cells in the recipients. Regulatory T cell lines isolated from the recipients inhibited T cells used for vaccination. The cytotoxicity of the CD8+ T cell lines was restricted by major histocompatibility antigens. Thus, clonotypic interactions regulating autoreactive T cells in humans can be induced by T cell vaccination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, J -- Medaer, R -- Stinissen, P -- Hafler, D -- Raus, J -- New York, N.Y. -- Science. 1993 Sep 10;261(5127):1451-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Multiple Sclerosis Research Unit, Dr. L.

    Decreased expression of myotonin-protein kinase messenger RNA and protein in adult form of myotonic dystrophy (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-09
    Description: The myotonic dystrophy mutation has recently been identified; however, the molecular mechanism of the disease is still unknown. The sequence of the myotonin-protein kinase gene was determined, and messenger RNA spliced forms were identified in various tissues. Antisera were developed for analytical studies. Quantitative reverse transcription-polymerase chain reaction and radioimmunoassay were used to demonstrate that decreased levels of the messenger RNA and protein expression are associated with the adult form of myotonic dystrophy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fu, Y H -- Friedman, D L -- Richards, S -- Pearlman, J A -- Gibbs, R A -- Pizzuti, A -- Ashizawa, T -- Perryman, M B -- Scarlato, G -- Fenwick, R G Jr -- P30-HG00210/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 9;260(5105):235-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular Genetics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8469976" target="_blank"〉PubMed〈/a〉

    Effects of oral administration of type II collagen on rheumatoid arthritis (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-24
    Description: Rheumatoid arthritis is an inflammatory synovial disease thought to involve T cells reacting to an antigen within the joint. Type II collagen is the major protein in articular cartilage and is a potential autoantigen in this disease. Oral tolerization to autoantigens suppresses animal models of T cell-mediated autoimmune disease, including two models of rheumatoid arthritis. In this randomized, double-blind trial involving 60 patients with severe, active rheumatoid arthritis, a decrease in the number of swollen joints and tender joints occurred in subjects fed chicken type II collagen for 3 months but not in those that received a placebo. Four patients in the collagen group had complete remission of the disease. No side effects were evident. These data demonstrate clinical efficacy of an oral tolerization approach for rheumatoid arthritis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trentham, D E -- Dynesius-Trentham, R A -- Orav, E J -- Combitchi, D -- Lorenzo, C -- Sewell, K L -- Hafler, D A -- Weiner, H L -- AG00294/AG/NIA NIH HHS/ -- MO1 RR01032/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 24;261(5129):1727-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Beth Israel Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8378772" target="_blank"〉PubMed〈/a〉

    Retinal degeneration in choroideremia: deficiency of rab geranylgeranyl transferase (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-15
    Description: Rab geranylgeranyl transferase (GG transferase) is a two-component enzyme that attaches 20-carbon isoprenoid groups to cysteine residues in Rab proteins, a family of guanosine triphosphate-binding proteins that regulate vesicular traffic. The mutant gene in human choroideremia, an X-linked form of retinal degeneration, encodes a protein that resembles component A of rat Rab GG transferase. Lymphoblasts from choroideremia subjects showed a marked deficiency in the activity of component A, but not component B, of Rab GG transferase. The deficiency was more pronounced when the substrate was Rab3A, a synaptic vesicle protein, than it was when the substrate was Rab1A, a protein of the endoplasmic reticulum. The data imply the existence of multiple component A proteins, one of which is missing in choroideremia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seabra, M C -- Brown, M S -- Goldstein, J L -- HL 20948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 15;259(5093):377-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8380507" target="_blank"〉PubMed〈/a〉

    Reduction in size of the myotonic dystrophy trinucleotide repeat mutation during transmission (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-02-05
    Description: Myotonic dystrophy (DM) is an autosomal-dominant disorder that affects 1 in 8000 individuals. Amplification of an unstable trinucleotide CTG repeat, located within the 3' untranslated region of a gene, correlates with a more severe DM phenotype. In three cases, the number of CTG repeats was reduced during the transmission of the DM allele; in one of these cases, the number was reduced to within the normal range and correlated at least with a delay in the onset of clinical signs of DM. Haplotype data of six polymorphic markers in the DM gene region indicate that, in this latter case, two stretches of the affected chromosome had been exchanged with that region of the wild-type chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Hoy, K L -- Tsilfidis, C -- Mahadevan, M S -- Neville, C E -- Barcelo, J -- Hunter, A G -- Korneluk, R G -- New York, N.Y. -- Science. 1993 Feb 5;259(5096):809-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of Ottawa, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8094260" target="_blank"〉PubMed〈/a〉

    Regenerative proliferation in inner ear sensory epithelia from adult guinea pigs and humans (1993)

    Details
    Publication Date: 1993-03-12
    Description: Supporting cells in the vestibular sensory epithelia from the ears of mature guinea pigs and adult humans proliferate in vitro after treatments with aminoglycoside antibiotics that cause sensory hair cells to die. After 4 weeks in culture, the epithelia contained new cells with some characteristics of immature hair cells.

    Hormonal chemoprevention of cancer in women (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-29
    Description: The use of oral contraceptives in the United States during the past three decades has led to a dramatic decline in the incidence of cancers of the ovary and endometrium. The magnitude of these declines was predictable both from epidemiologic data and from the biologic effects of oral contraceptives on these tissues. Although the incidence of breast cancer has not been substantially affected by current oral contraceptives, it may be possible to develop alternative forms of contraception that provide protection against all three cancers. The major goal of hormonal chemoprevention of cancer is to reduce cell proliferation in the relevant epithelial tissue. New chemopreventive agents such as tamoxifen exemplify the application of this principle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henderson, B E -- Ross, R K -- Pike, M C -- CA-17054/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 29;259(5095):633-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Preventive Medicine, University of Southern California School of Medicine, Los Angeles 90033.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8381558" target="_blank"〉PubMed〈/a〉

    Double-blind pilot trial of oral tolerization with myelin antigens in multiple sclerosis (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-02-26
    Description: Multiple sclerosis (MS) is thought to be an autoimmune disease mediated by T lymphocytes that recognize myelin components of the central nervous system. In a 1-year double-blind study, 30 individuals with relapsing-remitting MS received daily capsules of bovine myelin or a control protein to determine the effect of oral tolerization to myelin antigens on the disease. Six of 15 individuals in the myelin-treated group had at least one major exacerbation; 12 or 15 had an attack in the control group. T cells reactive with myelin basic protein were reduced in the myelin-treated group. No toxicity or side effects were noted. Although conclusions about efficacy cannot be drawn from these data, they open an area of investigation for MS and other autoimmune diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weiner, H L -- Mackin, G A -- Matsui, M -- Orav, E J -- Khoury, S J -- Dawson, D M -- Hafler, D A -- NS23132/NS/NINDS NIH HHS/ -- NS24247/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 26;259(5099):1321-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7680493" target="_blank"〉PubMed〈/a〉

    HLA-DPB1 glutamate 69: a genetic marker of beryllium disease (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-08
    Description: Chronic beryllium disease (CBD) is a lung disorder related to beryllium exposure and is characterized by the accumulation in the lung of beryllium-specific CD4+ major histocompatibility complex (MHC) class II-restricted T lymphocytes. Evaluation of MHC class II genes in 33 CBD cases and 44 controls has shown a negative association with HLA-DPB1*0401 (P 〈 0.001) and a positive association with HLA-DPB1*0201 (P 〈 0.05) alleles, which differ at residues 36, 55 to 56, and 69 of the beta 1 chain. Among CBD cases, 97 percent expressed the HLA-DPB1*0201-associated glutamic acid (unaffected population, 30 percent; P 〈 0.001) at residue 69, a position involved in susceptibility to autoimmune disorders. This suggests that HLA-DP has a role in conferring susceptibility and that residue 69 of HLA-DPB1 could be used in risk assessment for CBD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richeldi, L -- Sorrentino, R -- Saltini, C -- New York, N.Y. -- Science. 1993 Oct 8;262(5131):242-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Postgraduate School of Cardiorespiratory Physiopathology, University of Roma, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8105536" target="_blank"〉PubMed〈/a〉

    Preferential migration of activated CD4+ and CD8+ T cells in response to MIP-1 alpha and MIP-1 beta (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-16
    Description: Recombinant human macrophage inflammatory protein-1 alpha (rhMIP-1 alpha) and rhMIP-1 beta were potent chemoattractants of human T lymphocytes. These rhMIP-1 cytokines attracted only T cells activated by monoclonal antibody to CD3 and did not attract unstimulated lymphocytes. Phenotypic analysis revealed that CD4+ T cells were capable of migrating in response to rhMIP-1 beta, whereas rhMIP-1 alpha induced chemotaxis of predominantly CD8+ T lymphocytes. Activated naive and memory T cells also migrated in response to rhMIP-1 cytokines. Furthermore, these cytokines enhanced the ability of T cells to bind to an endothelial cell monolayer. These results suggest that rhMIP-1 cytokines preferentially recruit specific T cell subsets during the evolution of the immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taub, D D -- Conlon, K -- Lloyd, A R -- Oppenheim, J J -- Kelvin, D J -- N01-C0-74102/PHS HHS/ -- New York, N.Y. -- Science. 1993 Apr 16;260(5106):355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunoregulation, National Cancer Institute, Frederick Cancer Research and Development Center (FCRDC), MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7682337" target="_blank"〉PubMed〈/a〉

    Electrical potentials in human brain during cognition: new method reveals dynamic patterns of correlation (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-21
    Description: A new technique has been developed for identifying, in humans, dynamic spatiotemporal electrical patterns of the brain during purposive behaviors. In this method, single-trial time-series correlations between brain macropotentials recorded from different scalp sites are analyzed by distribution-independent mathematical pattern recognition. Dynamic patterns of correlation clearly distinguished two brief visuomotor tasks differing only in type of mental judgement required (spatial or numeric). These complex patterns shifted in the anterior-posterior and left-right axes between successive 175-millisecond intervals, indicating that many areas in both cerebral hemispheres were involved even in these simple judgements. These patterns were not obtainable by conventional analysis of averaged evoked potentials or by linear analysis of correlations, suggesting that the new technique will advance the study of human brain activity related to cognition and goal-directed behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Doyle, J C -- Cutillo, B A -- Schaffer, R E -- Tannehill, R S -- Ghannam, J H -- Gilcrease, V A -- Yeager, C L -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):918-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256287" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-11-27
    Description: Ten patients with multiple sclerosis who were treated with human fibroblast interferon (IFN-B) for 6 months showed a significant reduction in their exacerbation rates compared with their rates before treatment (P 〈 .01). The IFN-B was administered intrathecally by serial lumbar punctures. There was no significant change in the exacerbation rates of ten multiple sclerosis control patients before and during the period of observation. The IFN-B recipients have now been on the study a mean of 1.5 years, the controls, 1.2 years. The clinical condition of five of the IFN-B recipients and one of the control patients has improved, whereas the condition of five of the controls and one of the IFN-B recipients has deteriorated (P 〈 .036). These findings warrant cautious optimism about the efficacy of intrathecal IFN-B in altering the course of multiple sclerosis and support concepts of a viral or dysimmune etiology of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobs, L -- O'Malley, J -- Freeman, A -- Ekes, R -- CA-18533/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 27;214(4524):1026-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6171035" target="_blank"〉PubMed〈/a〉

One of these analogs, 1-desamino-8-D-arginine vasopressin (DDAVP), influences human learning and memory. Cognitively unimpaired, as well as cognitively impaired adults, treated with DDAVP for a period of several days, learn information more effectively, as measured by the completeness, organization, and consistency (reliability) of recall.

    Description: The cumulative effects of a repetitive stress induced by anticipation of pain (noxious foot shock) were studied on the threshold of a nociceptive flexion reflex of the lower limb. The threshold of the nociceptive reflex progressively increased with the repetition of the stress. This effect was reversed by naloxone, which even produced hyperalgesia, since a rapid and significant decrease in this threshold, below the initial values, was noted. Tha data provide evidence for involvement of endogenous opioids in the phenomenon of stress-induced analgesia in normal man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willer, J C -- Dehen, H -- Cambier, J -- New York, N.Y. -- Science. 1981 May 8;212(4495):689-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6261330" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-08-07
    Description: Subjects observing differently scaled environments undergo systematic shifts in the experience of time. The experience of temporal duration is compressed relative to the clock in the same proportion as scale-model environments being observed are compressed relative to the full-sized environment. This research suggests that spatial scale may be a principal mediator in the experience of time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeLong, A J -- RR-07088/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Aug 7;213(4508):681-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256273" target="_blank"〉PubMed〈/a〉

    Metabolic mapping of functional activity in human subjects with the [18F]fluorodeoxyglucose technique (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-08
    Description: The 2-[18F]fluoro-2-deoxy-D-glucose technique was used to measure regional cerebral glucose utilization by human subjects during functional activation. Normal male volunteers subjected to one or more sensory stimuli (tactile, visual, or auditory) exhibited focal increases in glucose metabolism in response to the stimulus. Unilateral visual hemifield stimulation caused the contralateral striate cortex to become more metabolically active than the striate cortex ipsilateral to the stimulated hemifield. Similarly, stroking the fingers and hand of one arm with brush produced an increase in metabolism in the contralateral postcentral gyrus, compared with the homologous ipsilateral region. The auditory stimulus, which consisted of a monaurally presented factual story caused an increase in glucose metabolism in the auditory cortex in the hemisphere contralateral to the stimulated ear. These results demonstrate that the technique is capable of providing functional maps in vivo related to both body region and submodality of sensory information in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenberg, J H -- Reivich, M -- Alavi, A -- Hand, P -- Rosenquist, A -- Rintelmann, W -- Stein, A -- Tusa, R -- Dann, R -- Christman, D -- Fowler, J -- MacGregor, B -- Wolf, A -- NS 10939-08/NS/NINDS NIH HHS/ -- NS 14867-02/NS/NINDS NIH HHS/ -- NS 15380-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 May 8;212(4495):678-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6971492" target="_blank"〉PubMed〈/a〉

    Regulation of leucine metabolism in man: a stable isotope study (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-04
    Description: Leucine catabolism is regulated by either of the first two degradative steps: (reversible) transamination to the keto acid or subsequent decarboxylation. A method is described to measure rates of leucine transamination, reamination, and keto acid oxidation. The method is applied directly to humans by infusing the nonradioactive tracer, L-[15N,1-13C]leucine. Leucine transamination was found to be operating several times faster than the keto acid decarboxylation and to be of equal magnitude in adult human males under two different dietary conditions, postabsorptive and fed. These results indicate that decarboxylation, not transamination, is the rate-limiting step in normal human leucine metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matthews, D E -- Bier, D M -- Rennie, M J -- Edwards, R H -- Halliday, D -- Millward, D J -- Clugston, G A -- AM-25994/AM/NIADDK NIH HHS/ -- HD-10667/HD/NICHD NIH HHS/ -- RR-00954/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1129-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7302583" target="_blank"〉PubMed〈/a〉

    Description: The densities of the brains of 11 chronic alcoholics were compared with those of 11 age-matched normal control subjects. Densities were determined from the density numbers generated by computerized tomography at three levels of the brain-the highest level of the lateral ventricles and the next two higher levels-with adjustments made to control for possible artifacts in the data. The advantage of the dominant hemisphere over the nondominant hemisphere was lessened in alcoholics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Golden, C J -- Graber, B -- Blose, I -- Berg, R -- Coffman, J -- Bloch, S -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):508-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455693" target="_blank"〉PubMed〈/a〉

    Description: Event-related potentials following silently named object pictures were recorded directly from the exposed left hemisphere of the human cortex at sites whose relation to naming was subsequently established by electrical stimulation mapping. Two simultaneous potential changes are specific to sites where stimulation disrupts naming: slow potentials as premotor sites and focal desynchronization at posterior sites surrounding the Sylvian fissure. These anatomically specific changes are also specific to the task--present with silent naming and absent in a spatial task with the same visual input. Overt speech is also preceded by slow potentials with earliest onset at premotor sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fried, I -- Ojemann, G A -- Fetz, E E -- NS 04053/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):353-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209537" target="_blank"〉PubMed〈/a〉

    Description: A tritium-labeled probe that detects measles virus nucleotide sequences was hybridized in situ to cells infected with measles virus and to sections of brain tissue from patients with subacute sclerosing panencephalitis and from patients with multiple sclerosis. The measles virus genome was detected in many cells in subacute sclerosing panencephalitis where this virus would have been missed by methods such as immunofluorescence. Measles virus sequences were also found in two foci in one of four cases of multiple sclerosis. This refined method of hybridization in situ, which can be useful in the search for covert virus infections of man, provides evidence that viruses may be involved in multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haase, A T -- Ventura, P -- Gibbs, C J Jr -- Tourtellotte, W W -- New York, N.Y. -- Science. 1981 May 8;212(4495):672-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221554" target="_blank"〉PubMed〈/a〉

The data indicate that a reduction of 1 degree C in oral temperature is associated with an increase of 200 microseconds in the latency of wave V of the auditory brainstem response, and of 160 microseconds in the interval between waves I and V.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marshall, N K -- Donchin, E -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):356-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209538" target="_blank"〉PubMed〈/a〉

    Description: These studies demonstrated increasing glucose metabolic rates in the human primary (PVC) and associative (AVC) visual cortex as the complexity of visual scenes increased. The metabolic response of the AVC increased more rapidly with scene complexity than that of the PVC, indicating the greater involvement of the higher order AVC for complex visual interpretations. Increases in local metabolic activity by as much as a factor of 2 above that of control subjects with eyes closed indicate the wide range and metabolic reserve of the visual cortex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phelps, M E -- Kuhl, D E -- Mazziota, J C -- P0-NS 156540-01/NS/NINDS NIH HHS/ -- R0I-GM-24839-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1981 Mar 27;211(4489):1445-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6970412" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-07-24
    Description: Neuropsychological variables and urine cannabinoid metabolites were evaluated in ten subjects born, raised, and educated in the United States and having histories of heavy or prolonged use of cannabis. No impairment of cognitive function was found. Cannabinoid metabolites in excess of 50 nanograms per milliliter were present in the ten urine samples. The tetrahydrocannabinol content of cannabis exceeded 8.0%.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schaeffer, J -- Andrysiak, T -- Ungerleider, J T -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):465-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6972600" target="_blank"〉PubMed〈/a〉
