Recent progress in the measurement of the bioconversion of dietary provitamin A carotenoids to vitamin A is reviewed in this article. Methods to assess the bioavailability and bioconversion of provitamin Acarotenoids have advanced significantly in the past 10 y, specifically through the use of stable isotopemethodology, which includes the use of labeled plant foods. The effects of the foodmatri...

To address the ever-growing group of health-conscious consumers, more and more nutritional and health claims are being used on food products. Nevertheless, only very few food constituents, including plant sterols, have been appointed an approved health claim (European Commission and Food and Drugs Administration). Plant sterols are part of those limited lists of approved compounds for their cho...

BACKGROUND/AIMS This experimental study was designed to investigate protective and therapeutic effects of Dexpanthenol (Dxp), an alcoholic analogue of pantothenic acid, on kidney damage induced by ischemia-reperfusion (I/R) in rats. METHODS Forty rats were randomly divided into a control group and 4 I/R groups (1 h ischemia followed by 23 h reperfusion). Three I/R groups were treated by Dxp (...

Minoxidil has been reported to inhibit in-vitro fibroblast proliferation and lysyl hydroxylase activity, a key enzyme in collagen biosynthesis. These in-vitro effects proposed minoxidil to be a potential antifibrotic agent. The present study aimed to investigate the effects of minoxidil gel on wound healing procedure in a second-degree burn model in rats. Wistar rats were anesthetized and a sec...

Postoperative sore throat (POST) is usually self-limiting but was rated by patients as one of the top 10 most undesirable anesthetic outcomes. Pharmacologic interventions that have been suggested to decrease the incidence of POST include application of local anesthetics and corticosteroids to the cuff of the endotracheal tube. These interventions often require extra steps during induction of ge...

Background. This prospective, controlled, parallel-group observational study investigated the efficacy of a spray containing hyaluronic acid and dexpanthenol to optimise regular treatment after nasal cavity surgery in 49 patients with chronic rhinosinusitis. Methods. The control group received standard therapy. Mucosal regeneration was determined using rhinoscopy sum score (RSS). Pre- and posto...
