They facilitate passive diffusion of GLUCOSE across the CELL MEMBRANE.
Midazolam is a lipophilic drug andcan pass through the placenta by passive diffusion.
Passive diffusion intake: 1.2% of the amount of vitamin B12 that is absorbed.
Lidocaine crosses the blood-brain and placental barriers,presumably by passive diffusion.
In this case, the absorption mechanism relies on the passive diffusion of vitamin B12 through the intestinal wall.
Calcium is mainly absorbed in the small intestine by active transport and passive diffusion.
As calcium intake increases>500 mg/day, passive diffusion presents a greater absorption of calcium.
Granisetron crosses intact skin into the systemic circulation by a passive diffusion process.
The measurement of TEWL is based on the passive diffusion of water through the stratum corneum, whose gradient is measured by the open probe of the equipment.
As a result, the ingested vitamin B12 is mostly excreted andcan only be absorbed through passive diffusion.
The ammonia made from the glutamine escapes from the renal tubule cells through a passive diffusion process and links to H protons making ammonium ions NH4.
Transepidermal water loss measures the water vapor lost through the surface of the skin by passive diffusion.
The transport of cortisol across membranes is expected to be mediated mainly by passive diffusion and therefore renal and biliary clearances are negligible.
Small molecules, such as ethanol, cross the maternal capillary endothelium andthe alveolar cell by passive diffusion.
Sweat is formed by active secretion of Na and Cl with a passive diffusion of water through the membrane.
Macitentan and its active metabolite are not relevant substrates of OATP1B1 and OATP1B3, butenter the liver by passive diffusion.
Cisplatin enters renal tubular cells by passive diffusion or transporter-mediated facilitated diffusion, leading to disproportionate drug accumulation.
In the liver, cholic acid is extracted from portal blood by multiple mechanisms,including passive diffusion and transporters.
However, the presence of the cell membrane prevents passive diffusion from moving the materials easily, because a protein-free lipid bilayer is highly impermeable to ions.
Oxybutynin is transported across intact skin andinto the systemic circulation by passive diffusion across the stratum corneum.
Testosterone from Livensa is transported across intact skin by a passive diffusion process that is primarily controlled by permeation across the stratum corneum.
The transdermal drug delivery systems(tdds)current presents an alternative for drug administration by passive diffusion throughout the skin.
On the other hand,the drugs administered through catheters are mostly absorbed by passive diffusion, while the nutrients are absorbed through an active transportation mechanism.
This greater lipophilicity may increase its efficacy in promoting the high levels of phototoxicity induced by Pp IX. MAL is transported by active mechanisms and also by passive diffusion through the membrane.
The high contrast uptake is due to the lipophilic properties of Gd-EOB-dTPA,favoring its passive diffusion by molecular transporters OATP1, which are in the basolateral membrane of normal hepatocytes.
Even if the intake is limited to 1.5 μg per meal through the intrinsic factor,only a little bit more than 1% of the amount of the vitamin B12 that is absorbed is used by the organism through passive diffusion.
Calcium is absorbed by the gastrointestinal tract via active transport, which occurs predominantly in the duodenum andthe proximal jejunum, and passive diffusion, located mainly in the distal jejunum and the ileum.
These short-chain fatty acids are responsible for decreasing the pH of the intestinal lumen, causing an increase in the concentration of ionized minerals and, as a consequence, there is an increase in the solubility of calcium andits subsequent challenge active and passive diffusion.
Definition English: Porins are protein molecules that were originally found in the outer membrane of GRAM-NEGATIVE BACTERIA and that form multi-meric channels for the passive DIFFUSION of WATER; IONS; or other small molecules.
