The significance of plasma ascorbic acid(AA)is underscored by its enzymatic and antioxidant properties as well as involvement in many aspects of health including the synthesis of biomolecules during acute illness,trau...
Transcellular permeation enhancers are known to increase the intestinal permeability of enalaprilat,a 349 Da peptide,but not hexarelin(887 Da).The primary aim of this paper was to investigate if paracellular permeabil...
Glutathione (GSH) is a tripeptide that constitutes one of the main intracellular reducing compounds. The normal content of GSH in the intestine is essential to optimize the intestinal Ca2+ absorption. The use of GS...

The disequilibrium between the production of reactive oxygen(ROS) and nitrogen(RNS) species and their elimination by protective mechanisms leads to oxidative stress. Mitochondria are the main source of ROS as by-produ...
Intestinal Ca2+ absorption is a crucial physiological process for maintaining bone mineralization and Ca2+ homeostasis. It occurs through the transcellular and paracellular pathways. The first route comprises 3steps: ...

AIM:To elucidate the effect and underlying mechanisms of omeprazole action on Mg 2+ transport across the intestinal epithelium.METHODS:Caco-2 monolayers were cultured in various dose omeprazole-containing media for 14...
AIM:To investigate omeprazole-induced transepithelial gastric leak and its effects on the permeability of the peptides bradykinin and oxytocin.METHODS:Rat gastric corpus tissue was isolated and mounted in an Ussing ch...
