Palytoxin-induced Effects on Partial Reactions of the Na,K-ATPase
The interaction of palytoxin with the Na,K-ATPase was studied by the electrochromic styryl dye RH421, which monitors the amount of ions in the membrane domain of the pump. The toxin affected the pump function in the state P-E2, independently of the type of phosphorylation (ATP or inorganic phosphate). The palytoxin-induced modification of the protein consisted of two steps: toxin binding and a ...
متن کاملPreparation and Characterization of ZnO Nanoparticles by Laser Ablation in NaOH Aqueous Solution
In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributio...
متن کاملThe Entrapment Ability of Aqueous and Ethanolic Extract of Teucrium Polium: Glucose Diffusion into the External Solution
Some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. The present study was designed to investigate the effect of aqueous and ethanolic extracts of Teucrium polium (T. polium) on glucose movement across the dialysis tube. The T. polium powder was dissolved in ethanol and distilled water. Then glucose was added to make a final concentration of 0.2 – ...
متن کاملPhotocatalytic degradaton of Sulfathiazole using nanosized CdO in aqueous solution
Template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. Cadmium oxide (CdO) nanoparticles were synthesized by using sodium dodecyl sulfate (SDS), Cd(OAc)2.2H2O and sodium hydroxide as starting materials. The sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). The XRD pattern prove...
متن کاملSynthesis of Copper Nanoparticles in Aqueous Ambient Using Dismutation Reaction
The present study has investigated the synthesis of copper nanoparticles via copper dismutation reaction in an aqueous solution and ambient conditions. Copper (II) chloride hydrate ( ), sodium oleate (SO), sodium chloride (NaCl) and ethylene diamine (EN) have been used as copper (I, II) ions source, surfactant, chloride ions supplier and ligand, respectively. Also, an amount of hydrochloric aci...
