The hydrochemical and isotopic techniques have become one of the most popular successful methods for determining hydrogeochemical features groundwater in recent years. A total 15 samples were collected during wet (March, 2021) dry (August, seasons. An approach with major elements (Cl-, Na+, Mg2+, Ca2+, SO4 2=) multi-isotope (2H, 18O) are used this study to solve geochemical variation salinity B...

Preservation of water quality, particularly in areas with inadequate water resources is considered as one of the principles of planning in integrated water management. In Kuhdasht, a region at the west of Iran, groundwater and spring water resources are the major contributors of drinking and irrigation water supply. The aim of this study was to determine the suitability and mapping of springs a...

Ligand-gated ion channel receptors mediate neuronal inhibition or excitation depending on their ion charge selectivity. An investigation into the determinants of ion charge selectivity of the anion-selective alpha1 homomeric glycine receptor (alpha1 glycine receptor [GlyR]) was undertaken using point mutations to residues lining the extra- and intracellular ends of the ion channel. Five mutant ...

Previous reports demonstrate that cell migration in the nervous system is associated with stereotypic changes in intracellular calcium concentration ([Ca(2+)](i)), yet the target of these changes are essentially unknown. We examined chemotactic migration/invasion of human gliomas to study how [Ca(2+)](i) regulates cellular movement and to identify downstream targets. Gliomas are primary brain c...

Alterations of cell volume are key events during both cell proliferation and apoptotic cell death. Cell proliferation eventually requires an increase of cell volume, and apoptosis is typically paralleled by cell shrinkage. Alterations of cell volume require the participation of ion transport across the cell membrane, including appropriate activity of Cl(-) and K(+) channels. Cl(-) channels modi...
