the present study investigated no3- and br- contamination in groundwater of arak aquifer of markazi province. correlation and factor analysis were used to detect interrelation and sources of concentration of no3- and br- ions and others physicochemical variables. no correlation was observed between no3- and others contents, but positive correlation was identified between br- with other major va...

Swelling-induced human erythrocyte K-Cl cotransport is membrane potential independent and capable of uphill transport. However, a complete thermodynamic analysis of basal and stimulated K-Cl cotransport, at constant cell volume, is missing. This study was performed in low K sheep red blood cells before and after reducing cellular free Mg into the nanomolar range with the divalent cation ionopho...

The present study investigated NO3- and Br- contamination in groundwater of Arak aquifer, Markazi province, Iran. Correlation and factor analyzes were used to detecti nterrelations and sources of NO3- and Br- ion concentration and other physicochemical variables. No correlation was observed between NO3- and otherscontents, but a positive correlation was identified between Br-and other majorvari...

K influx into resealed human red cell ghosts increases when the ghosts are swollen. The influx demonstrates properties similar to volume-sensitive K fluxes present in other cells. The influx is, for the most part, insensitive to the nature of the major intracellular cation and therefore is not a K-K exchange. The influx is much greater when the major anion is Cl than when the major anion is NO3...

The study analyses the efficiency of a Sequentional Sedimentation-Biofiltration System (SSBS) built on the Sokolowka river in Lodz (Poland). It was constructed to purify a small urban river whose hydrological regime is dominated by stormwater and meltwater. The SSBS was constructed on a limited area as multi-zone constructed wetlands. The SSBS consists of three zones: sedimentation zone with st...

Aquaporins (AQP) were originally regarded as plasma membrane channels that are freely permeated by water or small uncharged solutes but not by ions. Unlike other aquaporins, AQP6 overexpressed in Xenopus laevis oocytes was previously found to exhibit Hg2+ or pH-activated ion conductance. AQP6 could not be analyzed electrophysiologically in mammalian cells, however, because the protein is restri...

The whole cell configuration of the patch clamp technique was used to investigate the mechanism underlying rectification of the isoproterenol-activated chloride (Cl-) current in isolated guinea pig ventricular myocytes. When extracellular Cl- was replaced with either bromide (Br-), glutamate (Glut), iodide (I-), isethionate (Iseth), or nitrate (NO3-), the magnitude of the shift in reversal pote...

selection and use of tolerant grapevine as rootstock or own-rooted vines and finding indexes for screening of resistant genotypes have especial importance. to identify the salt tolerant grapevine genotypes, effects of nacl concentrations (0, 50, 100 and 150 mm) on root length, root and shoot dry weight, prolin, total soluble solid, rwc, level of salt injury, leaf concentration of k, na, cl and ...

Coordination of copper (I) and (II) salts to melamine (Mel) produces [CuX(Mel)] [X = Cl (5a), Br (5b), I (5c), NO3 (5d)], [CuX2(Mel)2] Æ S [X = Cl, S = H2O (6a); X = Cl, S = 2 MeOH (6b); X = Br, S = 1/2H2O (6c); X = OAc, S = none (6d)], and [Cu(OAc)2(Mel)] (7). The chemical identity of the complexes has been confirmed by elemental analysis, X-ray powder diffraction, thermogravimetry, and infrar...
