achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. the use of penetration enhancers could provide a successful mean for this purpose. the aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...

the parasitoid trichogramma brassicae bezdenko is used for inundative releases in biological control programs against lepidopteran pests in agro-ecosystems. age-specific functional responses of t. brassicae to different egg densities (5, 10, 20, 30, 40, 60, and 80) of sterilized eggs of ephestia kuehniella at 23±1°c, 60±5% rh, and 16:8 h (l:d photoperiod ) were studied. e. kuehniella densities ...

Ingested proteins are absorbed from the intestinal lumen via the paracellular and/or transcellular pathways, depending on their physicochemical properties. In this study, we investigated the absorption pathway(s) of ovalbumin (OVA), an egg white-allergen, as well as the mechanisms of aspirin-facilitated OVA absorption in rats. In situ intestinal re-circulating perfusion experiments showed that ...
