Membrane Transport and Renal Physiology
A computational model of porous media at the microscale will be presented. A collection of solid particles is placed within a regular fluid domain. The particles are represented with less detail by a ‘force cloud’ centered at a given point. Internal no-slip conditions are approximately achieved. This method is easy to implement, computationally inexpensive, and may be used to represent complex ...
متن کاملQuantitative ultrastructural analysis in cardiac membrane physiology.
Quantitative measurements on electron micrographs of heart muscle can yield information useful for cellular physiologists and at present not obtainable in other ways. These methods are subject to preparative artifact, sampling problems, and problems inherent in the mathematical description of ultrastructure. Nevertheless they provide the best available data for membrane areas of the plasmalemma...
متن کاملSENSORY PHYSIOLOGY Membrane cholesterol modulates cochlear electromechanics
Changing the concentration of cholesterol in the plasma membrane of isolated outer hair cells modulates electromotility and prestin-associated charge movement, suggesting that a similar manipulation would alter cochlear mechanics. We examined cochlear function before and after depletion of membrane cholesterol with methyl-βcyclodextrin (MβCD) in an excised guinea pig temporal bone preparation. ...
متن کاملMolecular Physiology of Membrane Guanylyl Cyclase Receptors.
cGMP controls many cellular functions ranging from growth, viability, and differentiation to contractility, secretion, and ion transport. The mammalian genome encodes seven transmembrane guanylyl cyclases (GCs), GC-A to GC-G, which mainly modulate submembrane cGMP microdomains. These GCs share a unique topology comprising an extracellular domain, a short transmembrane region, and an intracellul...
متن کاملMembrane physiology of retinal glial (Müller) cells.
Electrophysiological techniques were used to determine the ion selectivity properties and the spatial distribution of the membrane conductance of amphibian Müller cells. Membrane potential changes recorded during ion substitution experiments in frog (Rana pipiens) retinal slices demonstrated that the Müller cell K+:Na+ membrane permeability ratio is approximately 490:1 and that cell Cl- permeab...
