BACKGROUND AND OBJECTIVES p-Cresyl sulfate and indoxyl sulfate contribute to cardiovascular disease and progression of renal disease. Renal clearance of both solutes mainly depends on tubular secretion, and serum concentrations are widely dispersed for any given stage of CKD. From this information, it is inferred that estimated GFR is not a suitable proxy of the clearance of these solutes. Form...

Twelve Hereford-Angus weanling heifers were used in a split:plot design incorporating a randomized complete block to determine physiological effects of subtoxic concentrations of inorganic sulfate in drinking water. Treatments were tap-water (110 mg/liter sulfate), 1,250 rag/liter sulfate and 2,500 rag/liter surface. The sulfate was added to the tap water as sodium sulfate. The sulfate-waters d...

Bovine nucleus pulposus has been found to be a good source of a series of proteinpolysaccharides containing chondroitin 6-sulfate and keratan sulfate. Six distinct fractions have been separated, totaling 40 % of the dry weight of the tissue. Each fraction contains protein, chondroitin B-sulfate, and keratan sulfate, but the proportions of these components are different in each fraction. Of thes...

Heparan with a low affinity for antithrombin III has previously been demonstrated to inhibit thrombin generation in both normal plasma and plasma depleted of antithrombin III. In addition, standard heparin and heparin with a low affinity for antithrombin III have been demonstrated to have equivalent inhibitory actions on thrombin generation in plasma depleted of antithrombin III. These observat...

Seep sediments are dominated by intensive microbial sulfate reduction coupled to the anaerobic oxidation of methane (AOM). Through geochemical measurements of incubation experiments with methane seep sediments collected from Hydrate Ridge, we provide insight into the role of iron oxides in sulfate-driven AOM. Seep sediments incubated with (13)C-labeled methane showed co-occurring sulfate reduct...

to evaluate the maternal serum dehydroepiandrosterone (dhea) sulfate levels as a factor influencing labor ‘efficiency’ at term and unsuccessful labor induction. this is a prospective study. in this study the mean (± standard error) maternal serum dhea sulfate levels of 90 singleton pregnant women in 3 groups with spontaneous labor, need for augmentation and need for induction were compared.preg...
