Chondroitin sulfate is a major component of the extracellular matrix in both the central and peripheral nervous systems. Chondroitin sulfate is upregulated at injury, thus methods to promote neurite extension through chondroitin sulfate-rich matrices and synthetic scaffolds are needed. We describe the use of both chondroitin sulfate and a novel chondroitin sulfate-binding peptide to control the...

The effect of low substrate concentrations on the metabolic pathway and sulfur isotope fractionation during sulfate reduction was investigated for Archaeoglobus fulgidus strain Z. This archaeon was grown in a chemostat with sulfate concentrations between 0.3 mM and 14 mM at 80 degrees C and with lactate as the limiting substrate. During sulfate reduction, lactate was oxidized to acetate, format...

introduction: controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. there is a research contest between the researchers in this field to introduce more effective methods. this study aimed to compare the hemostatic effect of ferric sulfate and ferric chlorid...

a split plot experiment based on complete block design with three replications was carried out to evaluate the effect of irrigation and potassium fertilizer on yield and yield components of green beans, in 2011 at ahvaz. two levels of irrigation (normal irrigation and drought) and four levels of potassium sulfate fertilizer (0, 25, 50 and 100 kg ha-1) were evaluated in this study. the results o...

PURPOSE To investigate cell surface-associated keratan sulfate on the corneal endothelium. METHODS Immunolabeling techniques were used at the light, scanning, and transmission electron microscopic level to localize keratan sulfate on the corneal endothelium. The investigation included human, bovine, and rabbit corneal endothelia. A quantitative study of the relationship between cell size and ...

This study aimed to determine the antioxidant properties of sulfate monoesters ferulic, caffeic, dihydroferulic and dihydrocaffeic acids, main metabolites chlorogenic acids. These compounds are not commercially available, so they were synthesized in laboratory. The LC-MS/MS analysis allowed for full characterization these derivatives, which has made them reliable standards further research. Pur...

Sulfate reduction is the predominant anaerobic microbial process of organic matter mineralization in marine sediments, with recent studies revealing that sulfate reduction not only occurs in sulfate-rich sediments, but even extends to deeper, methanogenic sediments at very low background concentrations of sulfate. Using samples retrieved off the Shimokita Peninsula, Japan, during the Integrated...

magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. the antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. this study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...
