    Description / Table of Contents: NiH3IO6 · 6 H2O  -  Crystal Structures and Vibrational SpectraThe crystal structure of NiH3IO6 · 6 H2O has been determined by X-ray single-crystal diffraction (Pc, Z = 2, a = 516.74(9), b = 981.5(2), c = 1052.5(2) pm, β = 116.496(8)°) on the basis of 4169 unique reflections (R = 1.96%). The structure is built up of distorted Ni(H2O)62+ and H3IO62- octahedra linked by hydrogen bonding. IR and Raman spectra of both the title compound and isostructural MgH3IO6 · 6 H2O as well as of deuterated specimens are given. There are up to 14 different OH(OD) modes in the spectra of isotopically dilute samples due to the 15 different hydrogen positions of the structure. The internal modes of the meridional H3IO62- ions (pseudo C2v symmetry) are discussed with respect to that double T-shaped entity, which gives rise to only two instead of 3I—O, I—O(H), and OH stretches in the IR and Raman spectra, i.e. the same as for facial (C3v) structured ions.
    Notes: Die Kristallstruktur (Pc, Z = 2) von NiH3IO6 · 6 H2O wurde mittels Röntgen-Einkristallmessungen auf der Basis von 4169 symmetrieunabhängigen Reflexen bestimmt (R = 1,96%). IR- und Raman-Spektren von NiH3IO6 · 6 H2O und der isotypen Verbindung MgH3IO6 · 6 H2O sowie von deuterierten Präparaten werden mitgeteilt. Die Spektren isotypenverdünnter Proben zeigen bis zu 14 OH(OD)-Streckschwingungen entsprechend den 15 verschiedenen Wasserstoff-Positionen der Struktur. Die meridionalen H3IO62--Ionen (Pseudosymmetrie C2v) besitzen wegen der T-förmigen Anordnung der je 3 IO-und IOH-Gruppen nur je 2 IO-, IO(H)- und OH-Streckschwingungen in den IR- und Raman-Spektren und können daher schwingungsspektroskopisch nicht von H3IO62--Ionen mit facialer Struktur (C3v) unterschieden werden.

    Description: Vaccination with naked DNA elicits cellular and humoral immune responses that have a T helper cell type 1 bias. However, plasmid vectors expressing large amounts of gene product do not necessarily induce immune responses to the encoded antigens. Instead, the immunogenicity of plasmid DNA (pDNA) requires short immunostimulatory DNA sequences (ISS) that contain a CpG dinucleotide in a particular base context. Human monocytes transfected with pDNA or double-stranded oligonucleotides containing the ISS, but not those transfected with ISS-deficient pDNA or oligonucleotides, transcribed large amounts of interferon-alpha, interferon-beta, and interleukin-12. Although ISS are necessary for gene vaccination, they down-regulate gene expression and thus may interfere with gene replacement therapy by inducing proinflammatory cytokines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sato, Y -- Roman, M -- Tighe, H -- Lee, D -- Corr, M -- Nguyen, M D -- Silverman, G J -- Lotz, M -- Carson, D A -- Raz, E -- AI36214/AI/NIAID NIH HHS/ -- AI37305/AI/NIAID NIH HHS/ -- AR41897/AR/NIAMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1996 Jul 19;273(5273):352-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine and The Sam and Rose Stein Institute for Research on Aging, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0663, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662521" target="_blank"〉PubMed〈/a〉

    Notes: 1. Die Atomgewichte der ersten 27 Elemente, beginnend mit Helium, sind nicht Vielfache des Atomgewichts von Wasserstoff mit einer ganzen Zahl, wie es sein müßte, wenn PROUTS ursprüngliche Hypothese in ihrer numerischen Form richtig wäre. Dies kann ausgedrückt werden durch die Feststellung, daß die Atomgewichte, bezogen auf Wasserstoff, nicht ganze Zahlen sind. Wenn man jedoch diese Atomgewichte kritisch prüft, so findet man, daß sie von den entsprechenden ganzen Zahlen um einen fast konstanten Prozentsatz abweichen, daß die Abweichung negativ ist und im Mittel den Wert -0.77%, besitzt.

    Notes: 1. Der Grundgedanke dieser zweiten Mitteilung uber die Atomstruktur ist folgender: Das Gesetz, welches bei den Beziehungen von Atomgewicht und Valenz zwischen Gliedern einer jeden radioaktiven Reihe Anwendung findet, trifft auch für die leichteren Atome zu. Bei einer radioaktiven Reihe bedingt der Verlust eines Teilchens mit einer Masse von 4 eine Abnahme der Wertigkeit um 2 und verschiebt so das Element um 2 Gruppen des periodischen Systems nach links, während gleichzeitig die Atomzahl um 2 vermindert wird. Wenn dies auch für die leichteren Elemente, beginnend mit Helium, zutrifft, so müßte die Zunahme um das Gewicht eines Heliumatome für jeden Anwachs um 2 in der Atomzahl die Atomgewichte der Elemente liefern, die zu den Gruppen mit geraden Zahlen gehören. Die nach diesem Verfahren abgeleiteten Atomgewichte stimmen im ganzen mit den experimentell festgestellten Werten überein, woraus hervorgeht, daß die Theorie den Tatsachen entspricht.

    Description / Table of Contents: Synthesis and Structure of Hexa-t-butyl-1,4-dichloro-1,4-distanna-2,3,5,6,7,8-hexaphosphabicyclo[2.2.2]octane - a New Cage Compound with the Sn(P2)3Sn SkeletonThe reaction of the diphosphide K2[(tBuP)2] 1 with SnCl4 leads by a redox process mainly to (tBuP)3,4 and other sideproducts. However, at the same time a threefold [2 + 1]-cyclocondensation reaction takes place yielding the new cage compound hexa-t-butyl-1,4-dichloro-1,4-distanna-2,3,5,6,7,8-hexaphosphabicyclo[2.2.2]octane, ClSn(tBuP—PtBu)3SnCl 2. 2 could be obtained in a pure form and characterized 31P and 119Sn NMR spectroscopically; 2 was also characterized by a single crystal structure analysis.
    Notes: Bei der Reaktion zwischen dem Diphosphid K2[(tBuP)2] 1 und SnCl4 finden überwiegend Redoxreaktionen statt, die zu (tBuP)3,4 und weiteren Nebenprodukten führen. Gleichzeitig findet aber auch eine dreifache [2 + 1]-Cyclokondensation statt, bei der die neuartige Käfigverbindung Hexa-t-butyl-1,4-dichloro-1,4-distanna-2,3,5,6,7,8-hexaphospha-bicyclo[2.2.2]octan, ClSn(tBuP—PtBu)3SnCl 2 gebildet wird. 2 konnte in reiner Form isoliert und 31P- und 119Sn-NMR-spektroskopisch sowie durch eine Einkristallstrukturanalyse charakterisiert werden.

    Description: Transcription factors of the NFAT family are thought to play a major role in regulating the expression of cytokine genes and other inducible genes during the immune response. The role of NFAT1 was investigated by targeted disruption of the NFAT1 gene. Unexpectedly, cells from NFAT1 -/- mice showed increased primary responses to Leishmania major and mounted increased secondary responses to ovalbumin in vitro. In an in vivo model of allergic inflammation, the accumulation of eosinophils and levels of serum immunoglobulin E were increased in NFAT1 -/- mice. These results suggest that NFAT1 exerts a negative regulatory influence on the immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xanthoudakis, S -- Viola, J P -- Shaw, K T -- Luo, C -- Wallace, J D -- Bozza, P T -- Luk, D C -- Curran, T -- Rao, A -- CA42471/CA/NCI NIH HHS/ -- GM46227/GM/NIGMS NIH HHS/ -- P30 CA21765/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 May 10;272(5263):892-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurogenetics Program, Department of CNS Research, Hoffmann-LaRoche, Nutley, NJ 07110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8629027" target="_blank"〉PubMed〈/a〉

    Description: HLA-DM (DM) facilitates peptide loading of major histocompatibility complex class II molecules in human cell lines. Mice lacking functional H2-M, the mouse equivalent of DM, have normal amounts of class II molecules at the cell surface, but most of these are associated with invariant chain-derived CLIP peptides. These mice contain large numbers of CD4+ T cells, which is indicative of positive selection in the thymus. Their CD4+ cells were unresponsive to self H2-M-deficient antigen-presenting cells (APCs) but were hyperreactive to wild-type APCs. H2-M-deficient APCs failed to elicit proliferative responses from wild-type T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fung-Leung, W P -- Surh, C D -- Liljedahl, M -- Pang, J -- Leturcq, D -- Peterson, P A -- Webb, S R -- Karlsson, L -- New York, N.Y. -- Science. 1996 Mar 1;271(5253):1278-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Description: In mice deficient in either lymphotoxin-alpha (LT-alpha) or the type I tumor necrosis factor (TNF) receptor, but not the type II TNF receptor, germinal centers failed to develop in peripheral lymphoid organs. Germinal center formation was restored in LT-alpha-deficient mice by transplantation of normal bone marrow, indicating that the LT-alpha-expressing cells required to establish this lymphoid structure are derived from bone marrow.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsumoto, M -- Mariathasan, S -- Nahm, M H -- Baranyay, F -- Peschon, J J -- Chaplin, D D -- New York, N.Y. -- Science. 1996 Mar 1;271(5253):1289-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Immunology and Howard Hughes Medical Institute, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8638112" target="_blank"〉PubMed〈/a〉
