Development of the retinal vascular network is strictly confined within the neuronal retina, allowing the intraocular media to be optically transparent. However, in retinal ischemia, pro-angiogenic factors (including vascular endothelial growth factor-A, VEGF-A) induce aberrant guidance of retinal vessels into the vitreous. Here, we show that the soluble heparan sulfate level in murine intraocu...

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...

in an attempt to determine the chemical losses of three common molluscicides, i.e. cuso4, napcp and bayer –73, in stagnant water, a solution of each of this molluscicide was applied to one or more b.truncatus habitats and outdoor aquariums. the concentration of each molluscicide in these water bodies was determined immediately after application and at fixed time intervals thereafter. the concen...

The effects of streptomycin sulfate, carbendazim, penicillin and nystatin on the inhibition fungi bacteria in blueberry explants were studied. results showed that addition sulfate or with different concentrations medium had a certain inhibitory killing effect explant contamination, while carbendazim contamination. When concentration reached 60units / mL, highest survival rate was 44.0%, bacteri...

The competition between sulfate reducing bacteria and methanogens over common substrates has been proposed as a critical control for methane production. In this study, we examined the co-existence of methanogenesis and sulfate reduction with shared substrates over a large range of sulfate concentrations and rates of sulfate reduction in estuarine systems, where these processes are the key termi...

A panel of sulfated oligosaccharides was tested for antimalarial activity and inhibition of adhesion to the placental malaria receptor chondroitin-4-sulfate (CSA). The heparan sulfate mimetic PI-88, currently undergoing phase II anticancer trials, displayed the greatest in vitro antimalarial activity against Plasmodium falciparum (50% inhibitory concentration of 7.4 microM) and demonstrated mod...

Plasma cholesterol sulfate concentration is increased in patients with recessive X-linked ichthyosis, a disease in which steroid sulfatase activity is absent. In these patients, cholesterol sulfate is found primarily in the low-density lipoprotein fraction of plasma, and the electrophoretic mobility of these lipoproteins is greatly increased.

The aim of the present study was to develop and validate an inexpensive and simple high performance liquid chromatographic (HPLC) method for the determination of colistin sulfate. Separation of colistin sulfate was achieved on a ZORBAX Eclipse XDB-C18 column using UV detection at λ=215 nm. The mobile phase was 30 mM sulfate buffer (pH 2.5): An excellent linearity (r=0.998) was found in the conc...

The effect of a sulfate reducing bacteria immobilized in polyvinyl alcohol (PVA) on simultaneous sulfate reduction and copper removal was investigated. Batch experiments were designed using central composite design (CCD) with two parameters, i.e. the copper concentration (10-100mg/L), and the quantity of immobilized SRB in culture solution (19-235 mg of VSS/L). Response surface methodology (RSM...

Biosynthetic incorporation of labeled amino acids into the major gastrins in rat antrum, Component I, gastrin 34 ("big" gastrin), and gastrin 17-like peptides ("little" gastrin) was demonstrated after in vitro incubation of antral mucosal slices. The antral gastrin synthesis was stimulated by fundectomy, which ablates gastric acid secretion and thereby increases the gastrin concentration in pla...
