    Description: Amyloid deposition in senile plaques and the cerebral vasculature is a marker of Alzheimer's disease. Whether amyloid itself contributes to the neurodegenerative process or is simply a by-product of that process is unknown. Pheochromocytoma (PC12) and fibroblast (NIH 3T3) cell lines were transfected with portions of the gene for the human amyloid precursor protein. Stable PC12 cell transfectants expressing a specific amyloid-containing fragment of the precursor protein gradually degenerated when induced to differentiate into neuronal cells with nerve growth factor. Conditioned medium from these cells was toxic to neurons in primary hippocampal cultures, and the toxic agent could be removed by immunoabsorption with an antibody directed against the amyloid polypeptide. Thus, a peptide derived from the amyloid precursor may be neurotoxic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yankner, B A -- Dawes, L R -- Fisher, S -- Villa-Komaroff, L -- Oster-Granite, M L -- Neve, R L -- HD 18655/HD/NICHD NIH HHS/ -- HD 18658/HD/NICHD NIH HHS/ -- NS 01240/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):417-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Harvard Medical School, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2474201" target="_blank"〉PubMed〈/a〉

    Description: The neu oncogene, identified in ethylnitrosourea-induced rat neuroglioblastomas, had strong homology with the erbB gene that encodes the epidermal growth factor receptor. This homology was limited to the region of erbB encoding the tyrosine kinase domain. It was concluded that the neu gene is a distinct novel gene, as it is not coamplified with sequences encoding the EGF receptor in the genome of the A431 tumor line and it maps to human chromosome 17.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schechter, A L -- Hung, M C -- Vaidyanathan, L -- Weinberg, R A -- Yang-Feng, T L -- Francke, U -- Ullrich, A -- Coussens, L -- CA 39964-01/CA/NCI NIH HHS/ -- GM 26105/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Sep 6;229(4717):976-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2992090" target="_blank"〉PubMed〈/a〉

    Notes: A method for the quantitative determination of chlorpromazine and five of its major metabolites in a single sample of biological fluid in the ng/ml range has been developed utilizing gas chromatography/mass spectrometry with selected ion recording. The assay is highly specific and quantification is accomplished by an inverse stable isotope dilution technique, using deuterium-labeled variants of the compounds as internal standards. In this way the concentrations of chlorpromazine and five of its major metabolites (the sulfoxide, the N-oxide, the monodemethylated, the didemethylated, and the 7-hydroxylated compounds) can be determined in biological fluids. Levels in humans have been measured both in plasma and in red blood cells and are compared to those found in related in vitro studies.

    Notes: A metastatic variant cell subline of the Abelson virus-transformed murine large lymphoma/lymphosarcoma RAW 117 has been selected in vivo ten times for liver colonization. Highly metastatic subline RAW117-H10 forms greater than 200 times as many gross surface liver tumor nodules as the parental line RAW117-P. Analysis of cellular proteins and glycoproteins indicates reduced expression of murine Moloney leukemia virus-associated p15, p30, and gp70, and increased expression of a sialoglycoprotein, gp150, in the highly metastatic H10 cells. Northern analyses of oncogene expression suggested that mRNA of various oncogenes was expressed equally or not expressed in the RAW117 cells of differing metastatic potential. Differential gene expression was examined using a cDNA library of 17,600 clones established from poly A+ mRNA isolated from H10 cells. The cDNA library was screened by the colony hybridization technique using probes made from both RAW117-P and -H10 cells. Approximately 99.5% of these cDNA clones were expressed identically in P and H10 cells. Of the few differentially expressed cDNA clones (approx. 150/17,600), one-half of these were identified as Moloney leukemia virus sequences in a separate probing with a radiolabeled Moloney leukemia virus probe. The remainder of the differentially expressed mRNA detected by colony hybridization of the cDNA library were expressed at higher levels (approx. 1/6) or lower levels (approx. 1/3) in the highly metastatic H10 cells.

    Notes: A low-energy spectrometer for the X-ray analysis of plutonium and plutonium-containing materials has been built. We use ultra-thin window to maintain different pressures and contamination level in the spectrometers's sample and crystal chambers. Ultra-thin windows are also used on the X-ray tube and detector. Methods have been developed by which the spectrometer can analyze both metal and loose-powder samples. Representative calibration spectra are presented for the fluorine band in polyfluoroethylene, the oxygen band in α-Al2 O3, and the carbon band in graphite. Experimental spectra are presented for the fluorine band in PuF3 and for the oxygen ban in PuO2.

    Notes: The liquid SIMS mass spectra of silver acetate dissolved in a glycerol matrix is discussed, with emphasis on the formation of a ‘silver mirror’ on the surface of the glycerol droplet owing to reduction of the silver acetate. Silver clusters containing up to three silver atoms have been observed from this mirrored surface; Ag3+ cluster ions are not observed in the spectrum when conditions are such that the mirror is not formed. For example, use of a slightly oxidizing matrix (o-nitrophenyl octyl ether or m-nitrobenzylalcohol) prevents formation of the ‘mirror’; only Ag+ is sputtered from this surface.

    Description / Table of Contents: 77Se n.m.r. spectra of twenty-six organoselenium compounds, including some with an endocyclic selenium atom, have been recorded. Our measurements complete the scale of chemical shifts previously established by McFarlane. It seems difficult to define a range of chemical shifts which is characteristic of the valency state of selenium or of its endo- or exocyclic position. Some results are discussed qualitatively. In the case of selenolo[2,3-b]thiophene, evidence has been obtained for a 4J[Se, H] coupling across the sulphur atom.
    Notes: La résonance magnétique du 77Se a été observée dans vingt-six composés organiques dont certains contiennent un atome de sélénium endocyclique. Nous avons pu ainsi compléter l'échelle de déplacements chimiques établie par McFarlane. II apparaît difficile de définir une gamme de déplacement chimique du 77Se caractéristique de son état de valence ou de sa position endo- ou exocyclique. Certains résultats sont discutés qualitativement. Dans le cas du sélénolo [2,3-b]thiophène, des arguments en faveur d'un couplage 4J(Se, H) à travers l'atome de soufre ont été découverts.

    Notes: A series of prototrophic fragile strains of different ploidy (2n, 3n and 4n) has been genetically constructed on the basis ofhalopoid srb1 containing segregants of the fragile Saccharomyces cerevisiae mutant VY 1160. The strains have been characterized by several criteria. In regard to generation time, biomass yield, and nucleic acids content of the cells, the tetraploid srb1 homozygous hybrid is indistinguishable from an industrial strain of S. cerevisiae. However, it is characterized by a higher protein content. Unlikely any other laboratory or industrial strains, the original mutant and these hybrids possess an ability for lysis upon suspension in hypotonic solutions. The dependence of the percentge of lysed cells on the growth phase and concentration of osmotic stabilizer in the medium has been investigated. The quantity of proteins in the soluble fractions obtained after lysis of these strains by osmotic shock has been determined. These hybrids can be considered as a potential industrial source of potentials for nutritional purposes.

    Notes: The chemical shifts of N-benzylpyridinium salts have been measured in D2O, and the substituent induced chemical shifts of the methylene protons are in substantial agreement with those expected from the overall electronic effects of the substituents. An additivity effect of the substituents on the methylene resonance is also observed.
