in this work attempts were made to evaluate k+-sds and hydrocolloid polymer-sds interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. different dispersions of micronized megestrol acetate and sds were prepared. kcl and kh2po4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

Formaldehyde (FA) is a genotoxic and mutagenic substance. In 2004, IARC (International Agency for Research on Cancer) concluded that FA is carcinogenic in humans after reevaluating the available evidence on the carcinogenicity of FA. Although many studies have shown that FA had extensive genotoxicity including DNA-protein crosslinks (DPC) and DNA single strand breaks (DSSB), most of these studi...

Deformation microstructures are widely used for reconstructing tectono-metamorphic events recorded in rocks. In crustal settings deformation is often accompanied and/or succeeded by fluid infiltration and dissolution-precipitation reactions. However, the microstructural consequences of dissolution-precipitation in minerals have not been investigated experimentally. Here we conducted experiments...

We compare regional climate change scenarios (temperature and precipitation) over eastern Nebraska produced by a semiempirical statistical downscaling (SDS) technique and regional climate model (RegCM2) experiments, both using large scale information from the same coarse resolution general circulation model (GCM) control and 2 x COe simulations. The SDS method is based on the circulation patter...

1. Sodium dodecyl sulfate (SDS) attacks the chlorophyll-protein compound modifying its protein properties and absorption spectrum. 2. In the presence of SDS, chlorophyll is quantitatively converted to phaeophytin; i.e., magnesium is removed from the molecule. This reaction, measured spectrophotometrically, proceeds at a rate directly proportional to the hydrogen ion concentration. At constant p...

Zirconium Diboride (ZrB2) powder was synthesized at low temperature via a Direct Molten Salt Reaction (DMSR) method. The influence of different salt compositions including eutectic mixture of (KF-NaF), (KF-KCl) and (KCl-NaCl) on the morphology and purity of the reaction products was studied. The obtained samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD...

BACKGROUND AND PURPOSE Spreading depolarizations (SDs) may contribute to delayed cerebral ischemia after subarachnoid hemorrhage (SAH). We tested whether SD-inhibitor valproate reduces brain injury in an SAH rat model with and without experimental SD induction. METHODS Rats were randomized in a 2×2 design and pretreated with valproate (200 mg/kg) or vehicle for 4 weeks. SAH was induced by end...
