Glucose 6-sulfate and glucose-6-phosphate dehydrogenase have been used for NAD(P)H cofactor regeneration in preparations of (Sfbenzyl-a-d1 alcohol and ,hreo-D"(+)-isocitrate (0.1-mol scale). The reduced nicotinamide cofactoN are more stable in solutions of glucose c-sulfate than in solutions of glucoee Gphosphate and thefu lifetimes in solution are correspondingly longer. The specific activitie...

In this study fuzzy arithmetic is presented as a tool to tackle the prediction of the amount of barium, strontium and calcium sulfates scales in oilfield operations. Since the shape of fuzzy numbers’ membership functions is a spread representative of the whole possible values for a special model parameter, fuzzy numbers are able to consider the uncertainties in parameter determinations and thus...

Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

Background: Stroke is the third main cause of death and chronic disabilities in adults, which requires finding neuroprotective drugs to reduce its mortality and morbidity.  Objectives: To determine the efficacy of magnesium sulfate as an adjunctive neuroprotective agent in patients with stroke. Materials & Methods: This randomized double-blind clinical trial recruited 120 patients with acute ...

The variation in sulfur dioxide emissions from nonferrous metal smelters in the western United States over a 4-year period is compared with the variation in sulfate concentrations in precipitation in the Rocky Mountain states. The data support a linear relation between emissions and sulfate concentration. The geographic separation of emissions sources and precipitation monitors indicates a sulf...

Completely separated sulfur isotope signature frequency distributions for sedimentary sulfide and coexisting inorganic sulfate proved the field scale hydrochemical dominance of bacterial sulfate reduction and thus a strong overall natural attenuation potential of the aquifer section. Consequently, a significant improvement of the water quality and an eventually complete attenuation of the acid ...

PURPOSE To evaluate the clinical effects of magnesium sulfate in the treatment of diffuse axonal injury (DAI). PATIENTS AND METHODS This study was a randomized, double-blind, placebo-controlled trial conducted in the First Affiliated Hospital of Sun Yat-sen University, Guangzhou and Zhuhai People's Hospital, Zhuhai, two trauma center hospitals. A total of 128 patients suffered from DAI, with ...
