plasma membrane h+-atpase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. to study the effect of nacl on the expression pattern of a gene encoding the plasma membrane h+-atpase, an experiment was carried out in a completely random design with three replications. a pair of specific primers was designed based on the sequence o...

trichophyton rubrum is an anthropophilic fungus causing up to 90% of chronic cases of dermatophytosis. several properties of this fungus have been investigated so far. however, a few studies were carried out in the field of molecular biology of this fungus. in the present study, we tried to identify the subunit g of its vacuolar atpase (v-atpase). pairs of 21 nt primers were designed from highl...

Calcium permeability and the concomitant calcium block of monovalent ion current ("Ca(2+) block") are properties of cyclic nucleotide-gated (CNG) channel fundamental to visual and olfactory signal transduction. Although most CNG channels bear a conserved glutamate residue crucial for Ca(2+) block, the degree of block displayed by different CNG channels varies greatly. For instance, the Drosophi...

Reperfusion injury results from pathologies of cardiac myocyte physiology that develop when previously ischemic myocardium experiences a restoration of normal perfusion. Events in the development of reperfusion injury begin with the restoration of a proton gradient upon reperfusion, which then allows the sodium-proton exchanger (NHE) to increase flux, removing protons from the intracellular spa...

PbCl, in micromolar concentrations stimulates phosphorylation of electroplax microsomal protein in the absence of Nat. Other divalent cations showed little or no such effect. The (Mg’+ + Pb’+)and (Mg”+ + Na+)-dependent membrane-bound protein kinase activities in electroplax particulate preparations exhibit properties in common, including their acid stability, ouabain sensitivity, ATP specificit...

carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .control mice received similar quantities of olive oil. daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. the histologic e...

In this study, some environmental pollution parameters of the Atatürk Dam Lake which is Turkey's largest artificial lake and meeting irrigation energy needs Ad?yaman ?anl?urfa were evaluated with biochemical data in carp living consumed economically by public. Water, sediment fish samplings done simultaneously from Kahta Bozova districts, where located. Residue analyzes various metals water, mu...
