transepithelial การใช้

• The result is dehydrated mucus and a widened, negative transepithelial potential difference.
• Regulated selective permability is performed through two major routes : the transcellular ( transepithelial ) route and the paracellular route.
• These chloride channels have an important role in the control of membrane excitability, transepithelial transport, and possibly cell volume.
• When equilibrium is reached at the transepithelial equilibrium, the water flow will be lumen into blood, according to Curran.
• It was also discovered that there is a distinct relationship between the solute concentration deemed necessary to decrease transepithelial flow, and hydraulic permeability.
• If the sodium pump enters lis enough so that there is sufficient concentration, then water may move osmositcally across an adverse transepithelial osmotic gradient.
• Upon introduction of itraconazole-on-SBA-15 formulation in simulated gastrointestinal fluids, a supersaturated solution is obtained giving rise to enhanced transepithelial intestinal transport.
• Because " T . carnifex " osmoregulates mostly through transepithelial movement of water and solutes, this is probably the largest physiological challenge faced by the newt.
• As a result, there is a change in the activity of the potassium ion ( K + ) channels that changes the transepithelial transport of solutes and water in the kidney.
• In these cases, a useful diagnostic, adjunct involves measuring the nasal transepithelial potential difference ( ie, the charge on the respiratory epithelial surface as compared to interstitial fluid ).
• "' Transepithelial potential difference "'( TEPD ) is the voltage across an epithelium, and is the sum of the membrane potentials for the outer and inner cell membranes.
• Some of the transcribed genes are crucial for transepithelial sodium transport, including the three Na + / K + pumps and their regulatory proteins serum and glucocorticoid-induced kinase, and channel-inducing factor, respectively.
• This regulatory protein ( factor ) interacts with a sodium / hydrogen exchanger NHE3 ( SLC9A3 ) in the brush border membrane of the proximal tubule, small intestine, and colon that plays a major role in transepithelial sodium absorption.
• Once these cysts expand to approximately 2 mm in diameter, the cyst closes off from its parental tubule and after that fluid can only enter the cysts through transepithelial secretion, which in turn is suggested to increase due to secondary effects from an increased intracellular concentrations of cyclic AMP ( cAMP ).
• Transepithelial or epithelium-on ( epi-on ) cross-linking is a technique which was first performed in 2004 in the U . S ., the corneal epithelium layer is left intact . in this technique, because the epithelium is not removed, riboflavin loading requires more time than with epi-off techniques, and may be less effective.
