Bonanno, Joseph A., Yi Guan, Sergey Jelamskii, and Xiao Jun Kang. Apical and basolateral CO2-HCO3 2 permeability in cultured bovine corneal endothelial cells. Am. J. Physiol. 277 (Cell Physiol. 46): C545–C553, 1999.—Corneal endothelial function is dependent on HCO3 2 transport. However, the relative HCO3 2 permeabilities of the apical and basolateral membranes are unknown. Using changes in intr...

The SLC26 transporters are a family of mostly luminal Cl- and HCO3- transporters. The transport mechanism and the Cl-/HCO3- stoichiometry are not known for any member of the family. To address these questions, we simultaneously measured the HCO3- and Cl- fluxes and the current or membrane potential of slc26a3 and slc26a6 expressed in Xenopus laevis oocytes and the current of the transporters ex...

The present communication reports the dose and exposure dependent effects of a dioxin on few ion dependent membrane bound ATPases of mice kidney. Effects of TCDD on the specific activity of few membrane bound ATPases viz., Total ATPase, Na K ATPase, Ca ATPase, Mg ATPase, Ca++, HCO3 ATPase, Mg, HCO3 ATPase were observed. Two basic hypotheses were tested viz., (a) the sublethal in vivo exposure o...

Hydrochemistry and isotopes are studied for characterizations of geothermal waters, groundwaters, surface waters in Leizhou Peninsula (LZ) the northern part Hainan Island (HN) across tensile-tectonic Qiongzhou Strait, southern China. Water chemistry results showed that most alkaline HCO3-Na types, while shallow groundwater samples were significantly different with HCO3-Ca, HCO3-Mg, HNO3-Ca type...

This research work was performed within the framework of project titled “The survey on drinking water quality settlement areas Tuv province, conclusion and recommendation” implemented at Institute Geography Geoecology, MAS in 2021, some results are summarized this article. We took totally 16 samples from supply wells center 8 soums. Performed by physicochemical, micro-elements, bacteriological ...

We used cultivation-independent methods to investigate the prokaryotic biogeography of the water column in six salt lakes in Inner Mongolia, China, and a salt lake in Argentina. These lakes had different salt compositions and pH values and were at variable geographic distances, on both local and intercontinental scales, which allowed us to explore the microbial community composition within the ...

Based on the statistical analysis and redundancy soil sampling points along West Trunk Canal in Ningxia of China, spatial distribution characteristics relations among total salt content, pH value ions’ composition at different depths are obtained. The correlation coefficients, eigenvalues interpretation variances ions each layer analyzed discussed. According to analysis, it can be concluded tha...

groundwater quality in nour coastal plain in mazandaran province of iran is assessed by measuring physicochemical parameters including total dissolved solid, electrical conductivity, ph, total hardness, major cation and anion compositions and nitrate pollution. for this purpose, fifty groundwater samples were collected in july 2012. the hydrochemical types, ca–hco3 and mg–hco3 dominate in all s...
