Refinement of pucherite , BiV 04
نویسنده
چکیده
Pucherite, BiV04, from Schneeberg, Saxony, is orthorhombic, space group Pnca, with a=5.328(2), b=5.052(2), c=12.003(3)A at 291 K, 2=4, Dx = 6.69 g em -3. The crystal structure of pucherite has been refined from single-crystal X-ray diffraction data to Rw = 0.020 for 221 unique reflections measured with AgKrx radiation. The structure consists of V04 tetrahedra and BiOs triangulated dodecahedra. Each dodecahedron shares one edge with a tetrahedron and two edges with neighbouring dodecahedra.

The first study of bovine immunodeficiency virus (BIV) and bovine viral diarrhea virus (BVDV) co- infection in industrial herds of cattle in two provinces of Iran
BIV is a well-known bovine immunosup-pressive cause, but its pathogenesis has not been well characterized. It seems that it is possible that cofactors such as co- infection with other bovine viral pathogens may play a role in enhancing the pathogenesis of BIV infection; BVDV also has immunosuppressive effects. OBJECTIVE: The aim of this study was determination of possible correlation between BI...
متن کاملThe first study of bovine immunodeficiency virus (BIV) and brucellosis co-infection in west-central Iran
Background: BIV is a well-known bovine immunosuppressive cause, but its pathogenesis has not been well characterized. In recent years, it has been hypothesized that infection with BIV might predispose cattle to be infected by other agents. OBJECTIVE: This study was performed to investigate of BIV and Brucella co-infection so that in the future more studies will be done on the issue of predispos...
متن کاملImmunomodulative effects of bovine immunodeficiency-like virus (BIV)-infection and mixed infection of BIV and bovine leukemia virus on sheep.
Experimental bovine immunodeficiency-like virus (BIV)-infection and mixed infection of BIV and bovine leukemia virus (BLV) were performed on sheep. BIV proviral DNA and anti-BIV antibodies were persistently detected in all BIV-inoculated sheep. A slight increase in lymphocyte counts was observed in BIV-infected sheep, but the percentages of CD4+ and CD8+ cells in sheep peripheral blood mononucl...
متن کاملIsolation and characterization of new wild-type isolates of bovine lentivirus.
Two new isolates of bovine lentivirus, also known as bovine immunodeficiency-like virus (BIV), were obtained from a seropositive cattle herd in Florida. This is the first report of new isolates of BIV since the original BIV strain, R29, was isolated in 1969. The two new BIV isolates were derived from blood buffy coat cells cocultivated in vitro with fetal bovine lung cell cultures. The new isol...
متن کاملImprovement in cardiac adrenergic function post biventricular pacing for heart failure.
AIMS We investigated whether biventricular (BiV) pacing favourably affects cardiac sympathetic activity in heart failure (HF). METHODS AND RESULTS In 10 HF patients treated with BiV pacing, we assessed cardiac sympathetic activity by metaiodobenzylguanidine ((123)I-MIBG) imaging. Patients were randomized in a double-blinded crossover fashion, for two weeks of either inactivation of BiV pacing...
