    Global efforts in structural genomics (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-06
    Description: A worldwide initiative in structural genomics aims to capitalize on the recent successes of the genome projects. Substantial new investments in structural genomics in the past 2 years indicate the high level of support for these international efforts. Already, enormous progress has been made on high-throughput methodologies and technologies that will speed up macromolecular structure determinations. Recent international meetings have resulted in the formation of an International Structural Genomics Organization to formulate policy and foster cooperation between the public and private efforts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, R C -- Yokoyama, S -- Wilson, I A -- P50 GM62411/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Structural Genomics, Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11588249" target="_blank"〉PubMed〈/a〉

    Role of the ENTH domain in phosphatidylinositol-4,5-bisphosphate binding and endocytosis (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-02-13
    Description: Endocytic proteins such as epsin, AP180, and Hip1R (Sla2p) share a conserved modular region termed the epsin NH2-terminal homology (ENTH) domain, which plays a crucial role in clathrin-mediated endocytosis through an unknown target. Here, we demonstrate a strong affinity of the ENTH domain for phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P2]. With nuclear magnetic resonance analysis of the epsin ENTH domain, we determined that a cleft formed with positively charged residues contributed to phosphoinositide binding. Overexpression of a mutant, epsin Lys76 --〉 Ala76, with an ENTH domain defective in phosphoinositide binding, blocked epidermal growth factor internalization in COS-7 cells. Thus, interaction between the ENTH domain and PtdIns(4,5)P2 is essential for endocytosis mediated by clathrin-coated pits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Itoh, T -- Koshiba, S -- Kigawa, T -- Kikuchi, A -- Yokoyama, S -- Takenawa, T -- New York, N.Y. -- Science. 2001 Feb 9;291(5506):1047-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Institute of Medical Science, University of Tokyo, 4-6-1 Shirokanedai, Minato-ku, Tokyo 108-8639, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11161217" target="_blank"〉PubMed〈/a〉

    Molecular computation by DNA hairpin formation (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-05-20
    Description: Hairpin formation by single-stranded DNA molecules was exploited in a DNA-based computation in order to explore the feasibility of autonomous molecular computing. An instance of the satisfiability problem, a famous hard combinatorial problem, was solved by using molecular biology techniques. The satisfiability of a given Boolean formula was examined autonomously, on the basis of hairpin formation by the molecules that represent the formula. This computation algorithm can test several clauses in the given formula simultaneously, which could reduce the number of laboratory steps required for computation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sakamoto, K -- Gouzu, H -- Komiya, K -- Kiga, D -- Yokoyama, S -- Yokomori, T -- Hagiya, M -- New York, N.Y. -- Science. 2000 May 19;288(5469):1223-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biophysics and Biochemistry, Graduate School of Science, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-0033, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10817993" target="_blank"〉PubMed〈/a〉

    Independent control of spin density and hydrogen-bonding configuration in glow-discharge-hydrogenated Si-Ge alloys using a cathode-heating method (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 53 (1988), S. 1489-1491 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: The number density of dangling bonds (spin density) and the hydrogen content as well as the hydrogen-bonding configuration were independently controlled in the glow-discharge hydrogenated amorphous Si-Ge alloys using a cathode-heating technique. A tentative mechanism is presented in terms of the top surface process as well as the growth zone.

    Solid-phase crystal growth of molecular-beam-deposited amorphous GaAs (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 62 (1987), S. 1808-1814 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Solid-phase crystallization processes of molecular-beam-deposited amorphous GaAs with various As/Ga composition ratios are investigated by reflection high-energy electron diffraction, Rutherford backscattering spectroscopies, and time-resolved reflectivity measurements at various annealing temperatures. In a low-temperature region ((approximately-less-than)300 °C), solid-phase epitaxial growth takes place, and the activation energy of the growth rate (1.6 eV) is shown to agree well with that of the ion-implanted amorphized GaAs. In a high-temperature region ((approximately-greater-than)400 °C), polycrystallization takes place, followed by a realignment of the polycrystal to a single crystal. The epitaxial growth rate is more strongly affected by the As/Ga composition ratio for the low-temperature crystallization than for the high-temperature crystallization. The interface roughnesses between crystallized and amorphous layers are evaluated to be 14–20 nm from the reflectivity measurements and the transmission electron microscopy. The atomic bonding state in the amorphous GaAs is examined by Auger electron spectroscopy, and no local precipitation of As atoms is detected in the nearly stoichiometric film.

    The localized density of states in amorphous silicon determined by electrophotography (1986)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 60 (1986), S. 3176-3181 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The localized density of states g(E) near midgap for undoped, B2H6-doped, and PH3-doped hydrogenated amorphous silicon is evaluated from the electrophotographic (xerographic) method. The density of hole traps decreases with increasing B2H6 concentration and that of electron traps decreases with increasing PH3. These features are qualitatively similar to those deduced from the deep-level transient spectroscopy, the photothermal deflection spectroscopy, the time-of-flight measurements, and the isothermal capacitance transient spectroscopy. The energy positions of neutral dangling bonds D0 and doubly occupied D− are estimated to be 0.85–0.88 eV from the valence band and 0.62–0.67 eV from the conduction band, respectively. Comparison of the energy peaks of electron and hole traps shows that the positive correlation energy of dangling bonds is about 0.3–0.4 eV.

    Kininase and anti-inflammatory activities of acid carboxypeptidase fromPenicillium janthinellum (1975)

    Notes: Summary The acid carboxypeptidase fromPenicillium janthinellum catalyzed the rapid release of arginine, and the slow release of phenylalanine, proline, serine and glycine from the carboxy-terminal of bradykinin at pH 4.15 to 4.8 Anti-inflammatory activity of the acid carboxypeptidase seems to suggest that the enzyme hydrolyzed bradykinin in vivo.

    Prenatal diagnosis of GM1-gangliosidosis: Biochemical manifestations in fetal tissues (1978)
    Springer
    Human genetics 〈Berlin〉 44 (1978), S. 287-293

    ISSN: 1432-1203
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary A prenatal diagnosis of GM1-gangliosidosis was made in a pregnancy at risk, on the basis of a deficiency of β-galactosidase activity demonstrated in cultured aminiotic fluid cells. Biochemical analyses were performed in the aborted fetus. GM1-ganglioside β-galactosidase activity was reduced to 1% of the control value in both the brain and liver of the affected fetus. Lamellar bodies suggestive of membranous cytoplasmic bodies were found in cells of basal ganglions, while the accumulation of GM1-ganglioside in the brain was not remarkable.
