The title Ni(II) complex, [Ni(C(7)H(4)BrO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric. It contains two 2-bromo-benzoate (BB) ligands, two nicotinamide (NA) ligands and two water mol-ecules, all of them being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordinati...

BACKGROUND Consumption of oral contraceptive pills (OCP) is a known risk factor for cerebral venous and sinus thrombosis (CVST) among women. We determined whether misuse of OCP could increase the risk of CVST in women. METHODS A case-control study was conducted from 2003 to 2007 on 64 female patients with CVST admitted to Al- Zahra medical center and 232 healthy age-matched female OCP users a...

Solid-state nuclear magnetic resonance (NMR) spectroscopy allows for the identification of inorganic species during the biomineral formation, when crystallite particles visible in direct imaging techniques have not yet been formed. The bone blocks surrounding dental implants in minipigs were dissected after the healing periods of two, four, and eight weeks, and newly formed tissues formed aroun...
