Webosmosis: [noun] movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane. The clinical application of osmotic force is the injection of hypertonic solution of magnesium sulphate to reduce the volume of the brain or lower the pressure of cerebrospinal fluid. CAS Hence, the osmotic pressure is evaluated. The artificial membrane, Cu2Fe(CN)6, is the most selective. author reply 13001291.

Kim DW, Park JM, Yoon BW, Baek MJ, Kim JE, Kim S. Metronidazole-induced encephalopathy. However, you need to push the water through the reverse osmosis membrane by applying pressure that is greater than the naturally occurring osmotic pressure in order to desalinate (demineralize or deionize) water in the process; allowing pure water to pass through while holding back a majority of contaminants.

Early detection of response to radiation therapy in patients with brain malignancies using conventional and high b-value diffusion-weighted magnetic resonance imaging. Osmosis is when water molecules travel from a place with low solute concentration to a place with high solute concentration. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Since the solute particles are incapable of crossing the membrane, its the water (or other solvent) that needs to move. Adams Jr HP, del Zoppo G, Alberts MJ, et al. If the pressure greater than the osmotic pressure is applied the water (solvent) from the solution side starts moving towards pure water. J Comput Assist Tomogr. Epub 2013 Dec 11.

Relationships between cerebral perfusion and reversibility of acute diffusion lesions in DEFUSE: insights from RADAR. Osmosis, as defined by Google dictionary, is a process by which molecules of a solvent pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane..
