The oxidation of sulfide minerals in coal and mine's waste materials produce acid mine drainage. The evaporation, oxidation, dilution and neutralization of this acid drainage lead to formation of secondary minerals. Due to having broad surface spreading these minerals have the potential of maintaining sulfates and many of the metallic elements. In order to carry out mineralogical and geochemica...
the binding data for interaction of a homologous series of n-alkyl sulfates with alkyl chainlengths from c8 to c12 with insulin were analyzed on basis of hill equation for two classes ofbinding sites .the intrinsic gibbs free energies were calculated and resolute on basis ofelectrostatic and hydrophobic contributions the estimation of these contributions reveals themajor role of electrostatic i...
Gegen-Qinlian-Tang (GQT), a popular Chinese medicine prescription, consists of Puerariae Radix, Scutellariae Radix, Coptidis Rhizoma, and Glycyrrhizae Radix. This study investigated the pharmacokinetics of GQT in rats and compared the bioavailability between two dosage forms, that is, traditional decoction (TD) and concentrated powder (CP). Rats were given TD and CP of GQT in a crossover design...
Anticoagulant heparan sulfate proteoglycans bind and activate antithrombin by virtue of a specific 3-O-sulfated pentasaccharide. They not only occur in the vascular wall but also in extravascular tissues, such as the ovary, where their functions remain unknown. The rupture of the ovarian follicle at ovulation is one of the most striking examples of tissue remodeling in adult mammals. It involve...
Introduction: The Mars Exploration Rover (MER) in Gusev Crater has exposed in its tracks an unusual occurrence of a soil high in sulfur and high in phosphorus [1, 2] at a site called Paso Robles (Fig. 1). This salty soil is thought to be composed of the following: Fe-, Mg-, and Ca-sulfates; Ca-phosphate; hematite, halite, allophane, and amorphous Si [1]. We are currently studying a large suite ...
Chst10 adds sulfate to glucuronic acid to form a carbohydrate antigen, HNK-1, in glycoproteins and glycolipids. To determine the role of Chst10 in vivo, we generated systemic Chst10-deficient mutant mice. Although Chst10(-/-) mice were born and grew to adulthood with no gross defects, they were subfertile. Uteri from Chst10(-/-) females at the pro-estrus stage were larger than those from wild-t...
Recent models for the origin of Jupiter indicate that the Galilean satellites were mostly derived from largely unprocessed solar nebula solids and planetesimals. In the jovian subnebula the solids that built Europa were first heated and then cooled, but the major effect was most likely partial or total devolatilization, and less likely to have been wholesale thermochemical reprocessing of rock ...
Detailed studies of the bactericidal action of soaps have been made by numerous observers. Among them the most recent include those by Tilley and Schaffer, Walker, Eggerth, and Schaffer and Tilley. In general, such action increases with the number of carbon atoms in the fatty acid up to a maximum which depends upon factors such as the hydrogen ion concentration, the nature of the test organism,...
Two crystal structures of sulfate inclusion complexes in an aza- and amido-cryptand represent the first examples of encapsulated sulfate in synthetic cryptand receptors and indicate penta- and octa-coordination, respectively.
