    Detection of the J-10 Manifold of the Pure Rotational Band of Phosphine on Saturn (1984)
    In:  CASI
    Details
    Publication Date: 2014-09-17
    Description: The detection of the J = 10 manifold of the pure rotational band of PH3 on Saturn is reported. The observations were made from the far-infrared cooled grating spectrometer. The wavelengths and observed brightness temperatures for the full disk plus rings are 89 + or - 3 K at 97.04 micrometer, 77 + or - 3 K at 102.72 micrometer, 77 + or - 3 K at 102.94 micrometer, and 83 + or - 3 K at 105.12 micrometers. The points of 97.04 and 105.12 micrometers establish the continuum level and the two points near 103 micrometers measure the depth of the PH3 manifold. After the flux due to the rings is subtracted, the depth of the feature is 16 + or - 6 K relative to the nearby 102 K continuum. These results are compared to theoretical models which parameterize the PH3 mixing ratio as x = x sub zero (P/P sub zero)(alpha) for P P sub zero and as x = x sub zero for P or = P, where P is the total pressure and alpha = H/h is the ratio of the dynamical scale height (H) and the scale height for decreasing the PH3 mixing ratio (h). The parameters x sub zero, P sub zero, and h were varied, as well as the H/He mixing ratio and the pressure-temperature profile. The data are well fitted using pressure-temperature profiles. The preferred values of h, P sub zero, and x sub zero imply that there is little or no PH3 above the thermal inversion and that the mixing ratio below the inversion is consistent with PH3 being 1 to 4 times overabundant relative to the solar P/H ratio.

    Lymphadenopathy associated virus infection of a blood donor--recipient pair with acquired immunodeficiency syndrome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-07-06
    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〉

    Neuroleptic-induced decrease in plasma homovanillic acid and antipsychotic activity in schizophrenic patients (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-08-31
    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〉

    In:  CASI
    Details
    Publication Date: 2006-02-14
    Description: The prime objective of this experiment is to obtain chemical analyses of a statistically significant number of micrometeoroids. These data will then be compared with the chemical composition of meteorites. Secondary objectives of the experiment relate to density, shape, mass frequency, and absolute flux of micrometeorids as deduced from detailed crater geometrics (depth) diameter, and plane shape, and number of total events observed.

    Titan (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: It is pointed out that Titan, which is the second largest satellite in the solar system, is considerably larger than Mercury. It is made unique by its dense atmosphere, which consists mainly of nitrogen, although a substantial component of methane is present. The basic properties of Titan are summarized in a table. Many of the data were obtained during the close pass of Voyager 1 in November 1980. The atmospheric temperature decreases from its surface value of 94 K at a pressure of 1500 mbar to a minimum of 71 K at a height of 42 km and a pressure of 128 mbar. Details of atmospheric composition and thermal structure are discussed, taking into account chemical identifications and abundances, the vertical temperature structure, the horizontal temperature and opacity structure, and the radiative equilibrium. The upper atmosphere composition and temperature is considered along with the properties of aerosols, and meteorology and atmospheric dynamics. Titan's interior has an average density of 1.88 g per cu cm. Attention is given to Titan's surface and interior, and its formation.

    A new type D retrovirus isolated from macaques with an immunodeficiency syndrome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-02-10
    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〉

    Structure of the gene encoding the immunodominant surface antigen on the sporozoite of the human malaria parasite Plasmodium falciparum (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-08-10
    Description: The gene for the circumsporozoite (CS) protein of Plasmodium falciparum has been cloned and its nucleotide sequence determined. The gene encodes a protein of 412 amino acids as deduced from the nucleotide sequence. The protein contains 41 tandem repeats of a tetrapeptide, 37 of which are Asn-Ala-Asn-Pro and four of which are Asn-Val-Asp-Pro. Monoclonal antibodies against the CS protein of Plasmodium falciparum were inhibited from binding to the protein by synthetic peptides of the repeat sequence. The CS protein of Plasmodium falciparum and the CS protein of a simian malaria parasite, Plasmodium knowlesi, have two regions of homology, one of which is present on either side of the repeat. One region contains 12 of 13 identical amino acids. Within the nucleotide sequence of this region, 25 of 27 nucleotides are conserved. The conservation of these regions in parasites widely separated in evolution suggests that they may have a function such as binding to liver cells and may represent an invariant target for immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dame, J B -- Williams, J L -- McCutchan, T F -- Weber, J L -- Wirtz, R A -- Hockmeyer, W T -- Maloy, W L -- Haynes, J D -- Schneider, I -- Roberts, D -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):593-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6204383" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1984-08-10
    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〉

    Interferon-beta-related DNA is dispersed in the human genome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-03-23
    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〉

    Lymphoma in macaques: association with virus of human T lymphotrophic family (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-08-17
    Description: Human T-cell leukemia virus has been linked with adult T-cell leukemia-lymphoma (ATLL), a tumor of mature T cells that occurs at elevated rates in southwestern Japan and in the Caribbean Basin. Human T-cell leukemia virus (HTLV) or a closely related virus, has also been found in varying proportions of healthy individuals of several species of Old World monkeys. In the present study, conducted with macaques from Taiwan and the New England Regional Primate Research Center, antibodies to membrane antigens of HTLV-infected cells (HTLV-MA) were found in 11 of 13 macaques with malignant lymphoma or lymphoproliferative disease but in only 7 of 95 of healthy macaques. This indicates that antibodies to HTLV are significantly associated with the development of naturally occurring lymphoid neoplasms in at least some species of nonhuman primates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homma, T -- Kanki, P J -- King, N W Jr -- Hunt, R D -- O'Connell, M J -- Letvin, N L -- Daniel, M D -- Desrosiers, R C -- Yang, C S -- Essex, M -- 5TRRR07000/RR/NCRR NIH HHS/ -- CA 18216/CA/NCI NIH HHS/ -- RR00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 17;225(4663):716-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6087453" target="_blank"〉PubMed〈/a〉
