    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: A single recessive gene, lpr, induces an autoimmune-lymphoproliferative syndrome in several strains of mice. The lymphoid organs of lpr/lpr mice contained cells with increased amounts of myb RNA, which codes for a protein found in the nucleus. A similar human lymphoproliferative disorder also had an increase in c-myb expression. Mouse T cells induced by mitogens to proliferate did not express large amounts of myb RNA, indicating that marked myb expression is not a general feature of lymphocyte activation and proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mountz, J D -- Steinberg, A D -- Klinman, D M -- Smith, H R -- Mushinski, J F -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1087-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6494925" target="_blank"〉PubMed〈/a〉

    Description: A retrovirus isolated from three patients with the acquired immunodeficiency syndrome (AIDS) in the United States was morphologically and antigenically identical to lymphadenopathy associated virus isolated in France. Two of these isolates were from a blood donor-recipient pair, each of whom developed AIDS. Lymphadenopathy associated virus was isolated from the blood donor's lymphocytes 12 months after his onset of AIDS symptoms and from the blood recipient's lymphocytes 1 month after her onset of AIDS symptoms. Two isolates from the blood donor-recipient pair and an isolate from an epidemiologically unrelated homosexual man were examined by competitive radioimmunoassay to determine their antigenic relatedness to each other and to other human retroviruses. The major core proteins (p25) of the isolates were antigenically identical and all three isolates were identical to prototype lymphadenopathy associated virus isolated in France.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feorino, P M -- Kalyanaraman, V S -- Haverkos, H W -- Cabradilla, C D -- Warfield, D T -- Jaffe, H W -- Harrison, A K -- Gottlieb, M S -- Goldfinger, D -- Chermann, J C -- New York, N.Y. -- Science. 1984 Jul 6;225(4657):69-72.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6328663" target="_blank"〉PubMed〈/a〉

    Description: Plasma-free homovanillic acid, a major metabolite of dopamine, was measured in chronically ill schizophrenic patients both before and during treatment with the antipsychotic phenothiazine, fluphenazine. Neuroleptic treatment was associated with a significant time-dependent decrease in plasma homovanillic acid from pretreatment values, which were significantly elevated when compared with those of age- and sex-matched healthy control subjects. Further, both the absolute concentrations as well as the neuroleptic-induced reductions in plasma homovanillic acid determined over 5 weeks of neuroleptic treatment were statistically significantly correlated with ratings of psychosis and improvement in psychosis, respectively. These findings suggest that the delayed effects of neuroleptic agents on presynaptic dopamine activity may more closely parallel their therapeutic actions than do their immediate effects in blocking postsynaptic dopamine receptors and that a decrease in dopamine "turnover" may be responsible for their antipsychotic effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pickar, D -- Labarca, R -- Linnoila, M -- Roy, A -- Hommer, D -- Everett, D -- Paul, S M -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):954-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474162" target="_blank"〉PubMed〈/a〉

    Description: Cognitive activity resulted in increased flow of blood to the cerebral hemispheres. The increase was greater to the left hemisphere for a verbal task and greater to the right hemisphere for a spatial task. The direction and degree of hemispheric flow asymmetry were influenced by sex and handedness, females having a higher rate of blood flow per unit weight of brain, and females and left-handers having a greater percentage of fast-clearing tissue, presumably gray matter.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gur, R C -- Gur, R E -- Obrist, W D -- Hungerbuhler, J P -- Younkin, D -- Rosen, A D -- Skolnick, B E -- Reivich, M -- MH 30456/MH/NIMH NIH HHS/ -- NS-10939-09/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089587" target="_blank"〉PubMed〈/a〉

    Description: Sensory and cognitive functions were assessed in a right-handed male before and after partial and complete callosal commissurotomy. After the initial posterior section was made, there was no evidence of interhemispheric sensory transfer, although the left hemisphere did have access to stimulus-related semantic and episodic information from the right hemisphere. After the callosum was completely sectioned, this exchange was no longer observed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sidtis, J J -- Volpe, B T -- Holtzman, J D -- Wilson, D H -- Gazzaniga, M S -- 2 R01 NS15053-02/NS/NINDS NIH HHS/ -- RR001-02/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):344-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6782673" target="_blank"〉PubMed〈/a〉

    Description: Macaque monkeys with the recently described acquired immunodeficiency syndrome show a marked defect in T-lymphocyte function and die with opportunistic infections and lymphoproliferative abnormalities. In the study described here a new type D retrovirus was isolated from two Macaca cyclopis with this syndrome. This virus is related to, but distinct from, Mason-Pfizer monkey virus, a type D retrovirus previously isolated from a mammary tumor of a rhesus monkey (Macaca mulatta).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Daniel, M D -- King, N W -- Letvin, N L -- Hunt, R D -- Sehgal, P K -- Desrosiers, R C -- R01-A1 20729/PHS HHS/ -- RR00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Feb 10;223(4636):602-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6695172" target="_blank"〉PubMed〈/a〉

    Description: Transmissible retroviruses encoding human hypoxanthine phosphoribosyltransferase (HPRT) were used to infect mouse bone marrow cells in vitro, and the infected cells were transplanted into mice. Both active human HPRT-protein and chronic HPRT-virus production were detected in hematopoietic tissue of the mice, showing transfer of the gene. These results indicate the possible use of retroviruses for somatic cell therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, A D -- Eckner, R J -- Jolly, D J -- Friedmann, T -- Verma, I M -- CA 19562/CA/NCI NIH HHS/ -- GM28223/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):630-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6377498" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenic patients with high ventricle brain ratios and cortical brain atrophy, as shown by computerized tomography, had decreased spinal fluid concentrations of homovanillic acid and dopamine-beta-hydroxylase activity. These decreased cerebral spinal fluid concentrations in patients with brain atrophy support the proposal of disturbed noradrenaline and dopamine neurotransmission in a subgroup of schizophrenic patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Kammen, D P -- Mann, L S -- Sternberg, D E -- Scheinin, M -- Ninan, P T -- Marder, S R -- van Kammen, W B -- Rieder, R O -- Linnoila, M -- New York, N.Y. -- Science. 1983 May 27;220(4600):974-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6133351" target="_blank"〉PubMed〈/a〉

    Description: Interferon-beta 1 (IFN-beta 1) complementary DNA was used as a hybridization probe to isolate human genomic DNA clones lambda B3 and lambda B4 from a human genomic DNA library. Blot-hybridization procedures and partial nucleotide sequencing revealed that lambda B3 is related to IFN-beta 1 (and more distantly to IFN-alpha 1). Analyses of DNA obtained from a panel of human-rodent somatic cell hybrids that were probed with DNA derived from lambda B3 showed that lambda B3 is on human chromosome 2. Similar experiments indicated that lambda B4 is not on human chromosomes 2, 5, or 9. The finding that DNA related to the IFN-beta 1 gene (and IFN-alpha 1 gene) is dispersed in the human genome raises new questions about the origins of the interferon genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sagar, A D -- Sehgal, P B -- May, L T -- Inouye, M -- Slate, D L -- Shulman, L -- Ruddle, F H -- AI-16262/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Mar 23;223(4642):1312-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6546621" target="_blank"〉PubMed〈/a〉
