introduction: recent studies suggest that endocytosis of romk channels is important for regulation of k+ secretion in cortical collecting ducts. in this study the effect of v364d mutation is examined on the membrane turnover and stability of romk2 channel when expressing in xenopus laevis oocytes. materials and methods: in this experimental study, oocytes were isolated by standard protocols usi...

The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...

In this study, proton conductive composite membranes were produced by using a poly(methylmethacrylate-co-maleic anhydride) (P(MMA-co-MAH)) copolymer and phosphotungstic Acid (PWA) as an additive of the proton conductive agent. P(MMA/MAH) 70/30, 50/50, and 30/70 were synthesized using a free radical polymerization reaction. PWA with a concentration of 2% was added to...

Whereas marked variations in the clinical manifestations of hereditary spherocytosis have long been recognized, we have only recently begun to define the molecular basis for this heterogeneity. An important unanswered question is whether decreased spectrin results in reduced membrane mechanical stability, and if this reduction in membrane mechanical stability can be related to in vivo surface a...

the turbidity of sour orange juice after juice extraction affects on quality, shelf-life and concentration of juice. therefore, juice clarification is an important operation in the fruit processing industry. the goal of this study was evaluating the effect of membrane operation parameters including pressure (120-220 kpa) and temperature (25-35 ºc) on the permeate flux and hydraulic resistance o...

Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgari...
