    Notes: A new method for quantitating adenosine concentration by capillary gas chromatography-mass spectrometry-selected ion monitoring (GC-MS-SIM) has been developed and used as a reference method for evaluating a newly developed radioimmunoassay (RIA) for adenosine. Details of the GC-MS-SIM method are presented, along with the comparative results and uncertainties of both methods. General considerations in the statistical analysis of method comparison data are discussed with particular reference to studies using quantitative mass spectrometry as the standard method; the adenosine methods are used as specific examples in this discussion. Simultaneous estimation of the y-intercept and slope of the least squares regression line relating the results of the two methods using the 95% joint confidence ellipse demonstrated the absence of either constant or proportional error between the two methods. The relatively small uncertainty in the GC-MS-SIM measurements had no significant effect on the linear regression. Random error between the two methods was detected, and was estimated by the coefficient of variation in the RIA data as ten percent of the RIA value.

    Description / Table of Contents: Blown films of LD-PE prepared with varying processing conditions have been investigated using different X-ray diffraction methods. All films have a-texture. Differences in the degree of orientation are noticed. Arragement and size of lamellae are estimated by SAXS-investigations. A WAXS peak separation procedure using Pearson-VII-functions allows the determination of crystallite sizes. The orthorhombic modification as the dominant crystalline phase and some amount of monoclinic modification of PE have been detected from the resolved WAXS pattern.
    Notes: Blasfolien aus LD-PE unterschiedlicher Herstellungsparameter wurden komplex röntgenographisch untersucht. Alle Folien bestizen eine a-Textur. Unterschiede in der Texturgüte werden angegeben. SAXS-Untersuchungen ermöglichen Aussagen zur Lamellenanordnung und -größe. Eine Peak-Separation der WAXS mittels Pearson-VII-Funktionen erlaubt Kristallitgrößenangaben und läßt monokline Anteile neben der hauptsächlich auftretenden orthorhombischen Modifikation erkennen.

    Propolypeptide of von Willebrand factor circulates in blood and is identical to von Willebrand antigen II (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-23
    Description: The generally mild bleeding disorder of von Willebrand disease is associated with abnormalities of two distinct plasma proteins, the large multimeric von Willebrand factor (vWF), which mediates platelet adhesion, and von Willebrand antigen II (vW AgII), which is of unknown function. The two proteins were found to have a common biosynthetic origin in endothelial cells and megakaryocytes, which explains their simultaneous absence in the severe form of this hereditary disease. Shared amino acid sequences from a 100-kilodalton plasma glycoprotein and from vW AgII are identical to amino acid sequences predicted from a complementary DNA clone encoding the 5' end of vWF. In addition, these proteins have identical molecular weights and immunologic cross reactivities. Monoclonal antibodies prepared against both proteins recognize epitopes on the pro-vWF subunit and on a 100-kilodalton protein that are not present on the mature vWF subunit in endothelial cell lysates. In contrast, polyclonal antibodies against vWF recognize both pro-vWF and vWF subunits. Thus, the 100-kilodalton plasma glycoprotein and vW AgII are identical proteins and represent an extremely large propolypeptide that is first cleaved from pro-vWF during intracellular processing and then released into plasma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fay, P J -- Kawai, Y -- Wagner, D D -- Ginsburg, D -- Bonthron, D -- Ohlsson-Wilhelm, B M -- Chavin, S I -- Abraham, G N -- Handin, R I -- Orkin, S H -- HL-30616/HL/NHLBI NIH HHS/ -- HL-34050/HL/NHLBI NIH HHS/ -- HL-34787/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 23;232(4753):995-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486471" target="_blank"〉PubMed〈/a〉

    Atrial natriuretic peptide elevation in congestive heart failure in the human (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-03-07
    Description: A sensitive radioimmunoassay for atrial natriuretic peptide was used to examine the relation between circulating atrial natriuretic peptide and cardiac filling pressure in normal human subjects, in patients with cardiovascular disease and normal cardiac filling pressure, and in patients with cardiovascular disease and elevated cardiac filling pressure with and without congestive heart failure. The present studies establish a normal range for atrial natriuretic peptide in normal human subjects. These studies also establish that elevated cardiac filling pressure is associated with increased circulating concentrations of atrial natriuretic peptide and that congestive heart failure is not characterized by a deficiency in atrial natriuretic peptide, but with its elevation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnett, J C Jr -- Kao, P C -- Hu, D C -- Heser, D W -- Heublein, D -- Granger, J P -- Opgenorth, T J -- Reeder, G S -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1145-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2935937" target="_blank"〉PubMed〈/a〉

    Hu-ets-1 and Hu-ets-2 genes are transposed in acute leukemias with (4;11) and (8;21) translocations (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-24
    Description: Human probes identifying the cellular homologs of the v-ets gene, Hu-ets-1 and Hu-ets-2, and two panels of rodent-human cell hybrids were used to study specific translocations occurring in acute leukemias. The human ets-1 gene was found to translocate from chromosome 11 to 4 in the t(4;11)(q21;23), a translocation characteristic of a subtype of leukemia that represents the expansion of a myeloid/lymphoid precursor cell. Similarly, the human ets-2 gene was found to translocate from chromosome 21 to chromosome 8 in the t(8;21)(q22;q22), a nonrandom translocation commonly found in patients with acute myeloid leukemia with morphology M2 (AML-M2). Both translocations are associated with expression different from the expression in normal lymphoid cells of ets genes, raising the possibility that these genes play a role in the pathogenesis of these leukemias.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sacchi, N -- Watson, D K -- Guerts van Kessel, A H -- Hagemeijer, A -- Kersey, J -- Drabkin, H D -- Patterson, D -- Papas, T S -- AG00029/AG/NIA NIH HHS/ -- HD17449/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 24;231(4736):379-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941901" target="_blank"〉PubMed〈/a〉

    Studies of the human c-myb gene and its product in human acute leukemias (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-07-18
    Description: The myb gene is the transforming oncogene of the avian myeloblastosis virus (AMV); its normal cellular homolog, c-myb, is conserved across a broad span of evolution. In humans, c-myb is expressed in malignant hematopoietic cell lines and in primary hematopoietic tumors. Partial complementary DNA clones were generated from blast cells of patients with acute myelogenous leukemia. The sequences of the clones were compared to the c-myb of other species, as well as the v-myb of AMV. In addition, the carboxyl terminal region of human c-myb was placed in an expression vector to obtain protein for the generation of antiserum, which was used to identify the human c-myb gene product. Like v-myb, this protein was found within the nucleus of leukemic cells where it was associated with the nuclear matrix. These studies provide further evidence that c-myb might be involved in human leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Boone, T C -- Murdock, D C -- Keith, D E -- Press, M F -- Larson, R A -- Souza, L M -- CA36827/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):347-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014652" target="_blank"〉PubMed〈/a〉

    Notes: The N,N-dimethyl-8-nitro-1-naphthaleneamine molecule has been observed in seven environments in three crystal modifications. A range of conformations, related by conrotatory motions about the two exocyclic C—N bonds, is observed. In all seven conformations, the lone pair of the amino N-atom is directed approximately towards the nitro N-atom, which is slightly pyramidalized towards the amino group. The NO2 group appears to be a poorer through-space electron acceptor than the carboxylic ester group, in contrast to their through-bond electron-accepting properties.
