    Notes: Thermal degradation behavior of poly(1,3-phenylene isophthalamide) and poly(chloro-2,4-phenylene isophthalamide) was investigated with the aid of some appropriate model compounds. The pyrolysis products of these materials were identified by gas chromatography (GC), gas chromatography/Fourier transform infrared spectroscopy (GC/FT-IR), and gas chromatography/mass spectrometry (GC/MS). The residual chars were characterized by IR spectroscopy. Thermogravimetric analysis (TGA) was applied to study the effect of end-group concentration on the degradation characteristics of the two polyamides. Kinetic parameters that describe the thermal degradation of the polyamides were also evaluated by TGA. The results of this investigation suggest that the thermal decomposition of these aromatic polyamides involves homolytic as well as hydrolytic cleavages of the amide units.

    Spectroscopic studies of solutions, suspensions, and precipitates of poly(1,6-di-p-toluene sulfonyloxy-2,4-hexadiyne) (1981)

    Notes: Optical-absorption, fluorescence, and Raman spectra for solutions, suspensions, and precipitates of poly(1,6-di-p-toluene sulfonoxy-2,4-hexadiyne) in and from nitrobenzene, acetone, and chloroform are presented. These are interpreted in terms of the occurrence of two forms of the polymer chain; a quasicrystalline form with properties close to those of single crystal polymer and a chain-extended form occurring in solution and colloidal particles, with an absorption energy of about 2.5 eV (20,000 cm-1). No evidence is found for the presence of very short polymer chains in partially polymerized monomer at low conversion. The relationship of these results to those for deformed single crystals is briefly discussed.

    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〉

    Correlated dynamical changes in the near-earth and distant magnetotail regions - ISEE 3 (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: It is pointed out that the redeployment of ISEE 3 from its continuous monitoring of the solar wind in a large orbit about the upstream Lagrangian point to an extended magnetotail orbit has afforded an opportunity for deep-tail passage of October 1982, and in the radial range from 200 to 220 R(E) during the near-apogee part of the second tail passage in January-February 1983. Attention is given to instrumentation and data sets, spacecraft positions, and observational data.

    Correlated low-frequency electric and magnetic noise along the auroral field lines (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-08-13
    Description: Dynamics Explorer 1 measurements of intense low-frequency electric and magnetic noise observed at low altitudes over the auroral zone are described. The intensity of both the electric and magnetic fields decreases rapidly with increasing frequency. Most of the energy is at frequencies below the O(+) cyclotron frequency, and some evidence is found for a cutoff or change in spectral slope near that frequency. The magnetic to electric field ratio decreases rapidly with increasing radial distance and also decreases with increasing frequency. The polarization of the electric field in a plane perpendicular to the earth's magnetic field is essentially random. The transverse electric and magnetic fields are closely correlated, with the average Poynting flux directed toward the earth. The total electromagnetic power flow associated with the noise is substantial. Two general models are discussed to interpret these observations, one based on static electric and magnetic fields imbedded in the ionosphere and the other based on Alfven waves propagating along the auroral field lines.

    Anti-T-cell reagents for human bone marrow transplantation: ricin linked to three monoclonal antibodies (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-11-04
    Description: Three new reagents that react against human T cells were synthesized by covalently linking the toxin ricin to monoclonal antibodies recognizing differentiation antigens on the surface of T lymphocytes. Each of these immunotoxins selectively inhibited T-cell proliferation when the cells were incubated in the presence of lactose. Multipotent human stem cells were inhibited only at much higher concentrations. Mixtures of all three immunotoxins were more effective than any one alone. These reagents have the potential for preventing graft-versus-host disease in man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallera, D A -- Ash, R C -- Zanjani, E D -- Kersey, J H -- LeBien, T W -- Beverley, P C -- Neville, D M Jr -- Youle, R J -- CA-25097/CA/NCI NIH HHS/ -- CA-31618/CA/NCI NIH HHS/ -- CA-31685/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Nov 4;222(4623):512-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6353579" target="_blank"〉PubMed〈/a〉

    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〉

    Sex and handedness differences in cerebral blood flow during rest and cognitive activity (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-13
    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〉
