Bovine aortic smooth-muscle cells, bovine aortic endothelial cells, and IMR-90 human embryonic lung fibroblasts were tested to determine their ability to use cysteine or cysteine metabolites as a source of sulphate (SO4). Cells were incubated in SO4-depleted medium containing [3H]glucosamine plus 0.2 mM-cystine, 0.3 mM-cysteinesulphinic acid or 0.3 mM-sulphite (SO3). The [3H]chondroitin sulphat...

Ibuprofen (IBU), a nonsteroidal anti-inflammatory drug, is one of the most widely used and frequently detected pharmaceuticals personal care products in water bodies. This study examined IBU degradation aquatic solutions via ferric ion activated peroxydisulfate (PDS) coupled with electro-oxidation (EC/Fe3+/PDS). The mechanisms involved three synergistic reactions EC/Fe3+/PDS system, including: ...

The high temperature properties of Rb3H(SO4)2 have been studied by calorimetry, impedance spectroscopy and X-ray powder diffraction under moderate humidification. At ~205 °C the conductivity of Rb3H(SO4)2 increases sharply, rising from 3.3×10 −5 to 1.9×10 S/cm, suggestive of a polymorphic, superprotonic phase transition. This conductivity anomaly is accompanied by an endothermic thermal event w...

We used a combination of in situ attenuated total reflectance Fourier transform infrared (ATRFTIR) spectroscopy and X-ray absorption fine structure (XAFS) spectroscopy to conduct molecular scale studies on Pb(II)-sulfate interactions at the solid-water interface of goethite at pH 4.5, 5.0, and 6.0. Both the ATR-FTIR studies (probing sorbed SO4 in a flow cell setup as a function of the Pb concen...

background and purpose: today, by increasing different pollutants, the continuous monitoring of surface waters is essential. dorudzan dam is one of the main sources of surface water in fars province, iran; hence, the current study investigated the quality  of dorudzan reservoir for drinking and irrigation consumptions. materials and methods: in this study, various physicochemical parameters [ph...

In this study, it is aimed to treat the wastewater from drilling operations during creation of a natural gas storage area by electrocoagulation (EC) method. Boron and sulfate parameters in were tried be eliminated with help aluminum electrodes. During removal boron pollutants, optimization studies carried out on process time, pH, current criteria. (B) (SO4) concentrations generated measured as ...

Slc26a2 is a ubiquitously expressed SO4 transporter with high expression levels in cartilage and several epithelia. Mutations in SLC26A2 are associated with diastrophic dysplasia. The mechanism by which Slc26a2 transports SO4 and the ion gradients that mediate SO4 uptake are poorly understood. We report here that Slc26a2 functions as a SO4/2OH, SO4/2Cl and SO4/OH/Cl exchanger, depending on the ...

Various physico-chemical characteristics of the River Yamuna flowing in Haryana through Delhi were studied in the summer (April 1998) and winter (Jan.-Feb. 1999). Ecological parameters like dissolved oxygen (DO), pH, nitrate (NO3-), sulfate (SO4(2-)), and phosphate (PO4(3-)), were analyzed and compared with standard permissible limits to assess the best-designated use of the river water for var...

The mechanism by which SO4(2-) is transported across the plasma membrane of isolated human neutrophils was investigated. Unlike the situation in erythrocytes, SO4(2-) and other divalent anions are not substrates for the principal Cl-/HCO3- exchange system in these cells. At an extracellular concentration of 2 mM, total one-way 35SO4(2-) influx and efflux in steady-state cells amounted to approx...
