    Beschreibung: Concentrations of plasma homovanillic acid before treatment were highly correlated with global severity of illness in schizophrenic patients, both before and after treatment. In contrast, a fixed dose of haloperidol did not affect those concentrations. Thus, in patients with a diagnosis of schizophrenia, plasma homovanillic acid may reflect the severity of illness, but not be influenced by short-term pharmacological perturbations by neuroleptics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, K L -- Davidson, M -- Mohs, R C -- Kendler, K S -- Davis, B M -- Johns, C A -- DeNigris, Y -- Horvath, T B -- MH37922/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 29;227(4694):1601-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3975630" target="_blank"〉PubMed〈/a〉

    Beschreibung: Unequal crossing-over within a head-to-tail tandem array of the homologous red and green visual pigment genes has been proposed to explain the observed variation in green-pigment gene number among individuals and the prevalence of red-green fusion genes among color-blind subjects. This model was tested by probing the structure of the red and green pigment loci with long-range physical mapping techniques. The loci were found to constitute a gene array with an approximately 39-kilobase repeat length. The position of the red pigment gene at the 5' edge of the array explains its lack of variation in copy number. Restriction maps of the array in four individuals who differ in gene number are consistent with a head-to-tail configuration of the genes. These results provide physical evidence in support of the model and help to explain the high incidence of color blindness in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vollrath, D -- Nathans, J -- Davis, R W -- GM21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 17;240(4859):1669-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2837827" target="_blank"〉PubMed〈/a〉

    Beschreibung: In the polymerase chain reaction (PCR), two specific oligonucleotide primers are used to amplify the sequences between them. However, this technique is not suitable for amplifying genes that encode molecules where the 5' portion of the sequences of interest is not known, such as the T cell receptor (TCR) or immunoglobulins. Because of this limitation, a novel technique, anchored polymerase chain reaction (A-PCR), was devised that requires sequence specificity only on the 3' end of the target fragment. It was used to analyze TCR delta chain mRNA's from human peripheral blood gamma delta T cells. Most of these cells had a V delta gene segment not previously described (V delta 3), and the delta chain junctional sequences formed a discrete subpopulation compared with those previously reported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loh, E Y -- Elliott, J F -- Cwirla, S -- Lanier, L L -- Davis, M M -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):217-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Medicine and Microbiology and Immunology, Stanford University School of Medicine, CA 94305-5402.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2463672" target="_blank"〉PubMed〈/a〉

    Beschreibung: T cell clones obtained from a human volunteer immunized with Plasmodium falciparum sporozoites specifically recognized the native circumsporozoite (CS) antigen expressed on P. falciparum sporozoites, as well as bacteria- and yeast-derived recombinant falciparum CS proteins. The response of these CD4+ CD8- cells was species-specific, since the clones did not proliferate or secrete gamma interferon when challenged with sporozoites or recombinant CS proteins of other human, simian, or rodent malarias. The epitope recognized by the sporozoite-specific human T cell clones mapped to the 5' repeat region of the CS protein and was contained in the NANPNVDPNANP sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nardin, E H -- Herrington, D A -- Davis, J -- Levine, M -- Stuber, D -- Takacs, B -- Caspers, P -- Barr, P -- Altszuler, R -- Clavijo, P -- AI25085/AI/NIAID NIH HHS/ -- AI62533/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1603-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical and Molecular Parasitology, New York University, NY 10010.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2480642" target="_blank"〉PubMed〈/a〉

    Beschreibung: Expression of a complementary DNA (cDNA) encoding the mouse MyoD1 protein in a variety of fibroblast and adipoblast cell lines converts them to myogenic cells. Polyclonal antisera to fusion proteins containing the MyoD1 sequence show that MyoD1 is a phosphoprotein present in the nuclei of proliferating myoblasts and differentiated myotubes but not expressed in 10T1/2 fibroblasts or other nonmuscle cell types. Functional domains of the MyoD1 protein were analyzed by site-directed deletional mutagenesis of the MyoD1 cDNA. Deletion of a highly basic region (residues 102 to 135) interferes with both nuclear localization and induction of myogenesis. Deletion of a short region (residues 143 to 162) that is similar to a conserved region in the c-Myc family of proteins eliminates the ability of the MyoD1 protein to initiate myogenesis but does not alter nuclear localization. Deletions of regions spanning the remainder of MyoD1 did not affect nuclear localization and did not inhibit myogenesis. Furthermore, expression of only 68 amino acids of MyoD1, containing the basic and the Myc similarity domains, is sufficient to activate myogenesis in stably transfected 10T1/2 cells. Genetic analysis maps the MyoD1 gene to mouse chromosome 7 and human chromosome 11.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tapscott, S J -- Davis, R L -- Thayer, M J -- Cheng, P F -- Weintraub, H -- Lassar, A B -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):405-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3175662" target="_blank"〉PubMed〈/a〉

    Beschreibung: Volunteer subjects with previous histories of cocaine use were administered cocaine hydrochloride intravenously or intranasally. There was a positive relationship between peak plasma concentration, physiological and subjective responses, and dose administered. The rate of cocaine disappearance after intravenous administration paralleled the drop in physiological and subjective drug effects. After intranasal administration, blood levels remained elevated for a considerably longer period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Javaid, J I -- Fischman, M W -- Schuster, C R -- Dekirmenjian, H -- Davis, J M -- New York, N.Y. -- Science. 1978 Oct 13;202(4364):227-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694530" target="_blank"〉PubMed〈/a〉

    Beschreibung: Eighteen chronic schizophrenic patients received subcutaneous doses of apomorphine, a dopamine receptor agonist, and of placebo in separate trials. A significant improvement in psychotic symptoms occurred after apomorphine compared to placebo. The results are interpreted as a consequence of presynaptic dopamine receptor activation by apomorphine with a subsequent decrease in dopamine-mediated neural transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tamminga, C A -- Schaffer, M H -- Smith, R C -- Davis, J M -- New York, N.Y. -- Science. 1978 May 5;200(4341):567-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/347574" target="_blank"〉PubMed〈/a〉

    Beschreibung: In the families of manic-depressive patients, relatives with a history of affective disorders had a significantly higher ratio of mean red cell lithium to plasma lithium in vitro than relatives with no such history. A genetically controlled abnormality in lithium-sodium transport, the mechanism that determines the lithium ratio, may play a role in the etiology of some forms of affective disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorus, E -- Pandey, G N -- Shaughnessy, R -- Gaviria, M -- Val, E -- Ericksen, S -- Davis, J M -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):932-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472716" target="_blank"〉PubMed〈/a〉
