    Protein lipidation in cell signaling (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-04-14
    Description: The ability of cells to communicate with and respond to their external environment is critical for their continued existence. A universal feature of this communication is that the external signal must in some way penetrate the lipid bilayer surrounding the cell. In most cases of such signal acquisition, the signaling entity itself does not directly enter the cell but rather transmits its information to specific proteins present on the surface of the cell membrane. These proteins then communicate with additional proteins associated with the intracellular face of the membrane. Membrane localization and function of many of these proteins are dependent on their covalent modification by specific lipids, and it is the processes involved that form the focus of this article.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Casey, P J -- New York, N.Y. -- Science. 1995 Apr 14;268(5208):221-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Cancer Biology, Duke University Medical Center, Durham, NC 27710-3686, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7716512" target="_blank"〉PubMed〈/a〉

    Ulysses radio and plasma wave observations at high southern heliographic latitudes (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-05-19
    Description: Ulysses spacecraft radio and plasma wave observations indicate that some variations in the intensity and occurrence rate of electric and magnetic wave events are functions of heliographic latitude, distance from the sun, and phase of the solar cycle. At high heliographic latitudes, solartype Ill radio emissions did not descend to the local plasma frequency, in contrast to the emission frequencies of some bursts observed in the ecliptic. Short-duration bursts of electrostatic and electromagnetic waves were often found in association with depressions in magnetic field amplitude, known as magnetic holes. Extensive wave activity observed in magnetic clouds may exist because of unusually large electron-ion temperature ratios. The lower number of intense in situ wave events at high latitudes was likely due to the decreased variability of the high- latitude solar wind.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stone, R G -- Macdowall, R J -- Fainberg, J -- Kaiser, M L -- Desch, M D -- Goldstein, M L -- Hoang, S -- Bougeret, J L -- Harvey, C C -- Manning, R -- Steinberg, J L -- Kellogg, P J -- Lin, N -- Goetz, K -- Osherovich, V A -- Reiner, M J -- Canu, P -- Cornilleau-Wehrlin, N -- Lengyel-Frey, D -- Thejappa, G -- New York, N.Y. -- Science. 1995 May 19;268(5213):1026-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17774230" target="_blank"〉PubMed〈/a〉

    Resonance light scattering: a new technique for studying chromophore aggregation (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-08-18
    Description: Light scattering experiments are usually performed at wavelengths away from absorption bands, but for species that aggregate, enhancements in light scattering of several orders of magnitude can be observed at wavelengths characteristic of these species. Resonance light scattering is shown to be a sensitive and selective method for studying electronically coupled chromophore arrays. The approach is illustrated with several examples drawn from porphyrin and chlorin chemistry. The physical principles underlying resonance light scattering are discussed, and the advantages and limitations of the technique are reviewed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pasternack, R F -- Collings, P J -- New York, N.Y. -- Science. 1995 Aug 18;269(5226):935-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Swarthmore College, PA 19081, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7638615" target="_blank"〉PubMed〈/a〉

    Atmospheric Trends and Lifetime of CH3CCI3 and Global OH Concentrations (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-14
    Description: Determination of the atmospheric concentrations and lifetime of trichloroethane (CH(3)CCI(3)) is very important in the context of global change. This halocarbon is involved in depletion of ozone, and the hydroxyl radical (OH) concentrations determined from its lifetime provide estimates of the lifetimes of most other hydrogen-containing gases involved in the ozone layer and climate. Global measurements of trichloroethane indicate rising concentrations before and declining concentrations after late 1991. The lifetime of CH(3)CCI(3) in the total atmosphere is 4.8 +/- 0.3 years, which is substantially lower than previously estimated. The deduced hydroxyl radical concentration, which measures the atmosphere's oxidizing capability, shows little change from 1978 to 1994.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prinn, R G -- Weiss, R F -- Miller, B R -- Huang, J -- Alyea, F N -- Cunnold, D M -- Fraser, P J -- Hartley, D E -- Simmonds, P G -- New York, N.Y. -- Science. 1995 Jul 14;269(5221):187-92.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17789846" target="_blank"〉PubMed〈/a〉

    Molecular diffuse interstellar band carriers in the red rectangle (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-08-04
    Description: High-resolution optical spectroscopic observations of unidentified emission bands from the unusual biconical nebula known as the Red Rectangle are reported. The peak wavelengths and the widths of prominent bands near 5799, 5853, and 6616 angstroms decrease with increasing offset from the central A0-type star HD 44179 and, in the limit of large distance from the star, are shown to converge toward the known values for some of the narrower diffuse interstellar absorption bands at 5797, 5850, and 6614 angstroms. The same carriers give rise to both Red Rectangle emission and corresponding diffuse interstellar absorption bands, and these particular bands arise from electronic transitions in gas-phase molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sarre, P J -- Miles, J R -- Scarrott, S M -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):674-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17758811" target="_blank"〉PubMed〈/a〉

    CD1-restricted T cell recognition of microbial lipoglycan antigens (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-14
    Description: It has long been the paradigm that T cells recognize peptide antigens presented by major histocompatibility complex (MHC) molecules. However, nonpeptide antigens can be presented to T cells by human CD1b molecules, which are not encoded by the MHC. A major class of microbial antigens associated with pathogenicity are lipoglycans. It is shown here that human CD1b presents the defined mycobacterial lipoglycan lipoarabinomannan (LAM) to alpha beta T cell receptor-bearing lymphocytes. Presentation of these lipoglycan antigens required internalization and endosomal acidification. The T cell recognition required mannosides with alpha(1--〉2) linkages and a phosphotidylinositol unit. T cells activated by LAM produced interferon gamma and were cytolytic. Thus, an important class of microbial molecules, the lipoglycans, is a part of the universe of foreign antigens recognized by human T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sieling, P A -- Chatterjee, D -- Porcelli, S A -- Prigozy, T I -- Mazzaccaro, R J -- Soriano, T -- Bloom, B R -- Brenner, M B -- Kronenberg, M -- Brennan, P J -- AI 07118/AI/NIAID NIH HHS/ -- AI 18357/AI/NIAID NIH HHS/ -- AI 28973/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1995 Jul 14;269(5221):227-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Dermatology, University of California at Los Angeles (UCLA) School of Medicine 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542404" target="_blank"〉PubMed〈/a〉

    Direct evaluation of electronic coupling mediated by hydrogen bonds: implications for biological electron transfer (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-09-08
    Description: Three supramolecular bischromophoric systems featuring zinc(II) and iron(III) porphyrins have been synthesized to evaluate the relative magnitudes of electronic coupling provided by hydrogen, sigma, and pi bonds. Laser flash excitation generates the highly reducing singlet excited state of the (porphinato)zinc chromophore that can subsequently be electron transfer quenched by the (porphinato)iron(III) chloride moiety. Measurement of the photoinduced electron transfer rate constants enables a direct comparison of how well these three types of chemical interactions facilitate electron tunneling. In contrast to generally accepted theory, electronic coupling modulated by a hydrogen-bond interface is greater than that provided by an analogous interface composed entirely of carbon-carbon sigma bonds. These results bear considerably on the analysis of through-protein electron transfer rate data as well as on the power of theory to predict the path traversed by the tunneling electron in a biological matrix; moreover, they underscore the cardinal role played by hydrogen bonds in biological electron transfer processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Rege, P J -- Williams, S A -- Therien, M J -- New York, N.Y. -- Science. 1995 Sep 8;269(5229):1409-13.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Pennsylvania, Philadelphia 19104-6323, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7660123" target="_blank"〉PubMed〈/a〉
