Water and Deuterium Oxide Permeability through Aquaporin 1: MD Predictions and Experimental Verification

Aquaporin-1 transports NO across cell membranes.

NO plays a role in the regulation of blood pressure through its effects on renal, cardiovascular, and central nervous system function. It is generally thought to freely diffuse through cell membranes without need for a specific transporter. The water channel aquaporin-1 transports low molecular weight gases in addition to water and is expressed in cells that produce or are the targets of NO. Co...

Carboxypeptidasey from Saccharomyces cerevisiae Conformational Difference Reflected in Kinetic Behaviour in Water and Deuterium Oxide

Water structure changes induced by ceramics can be detected by increased permeability through aquaporin

Aquporins are intrinsic membrane proteins that function as water channel to transport water and/or mineral nutrients across biological membranes. In this study, we aimed to clarify whether water structure can be changed by the presence of ceramics and whether such a change can be determined by aquaporin. First, we confirmed that ceramics could transform tap water into active tap water by increa...

The Mechanism of the Osmotic Adjustment of Body

Since permeability of cell membranes to water has been clearly demonstrated, there are several theoretically possible responses of cells to dilution of the extracellular fluid. Osmotic equilibrium might result from net movement of water into cells in response to extracellular dilution. On the other hand, net movement of water into cells might be averted by: 1) active transport of water out of c...

An Experimental Study of Acid Diversion by Using Gelled Acid Systems Based on Viscoelastic Surfactants: A Case Study on One of Iran Southwest Oilfields

In matrix acidizing operations, the main goal is increasing permeability. For production engineers, it is desirable that acid could be injected into whole [M.N.1] [amehri.gh2] pay zone. Sometimes, this pay zone has a long height and various sub-layers which have different permeability values. To prevent acid from going completely into the most permeable sub-layer, one of the useful techniques i...
