background: in the last decades, mesoporous silica nanoparticles (msn) are improved for drug delivery, imaging, and biomedical applications due to their special properties such as large surface area, high drug loading capacity, tunable pore size, and modification of surface area by functional groups. objectives: the aim of this study was to evaluate msns as carriers for oral colon-specific and ...

background and purpose: vitamin c is administered orally or intravenously for the treatment of burn wounds. however, effects of the topical application of vitamin c remain unclear. this study aimed to evaluate the effects of topical vitamin c solution on the necrotic tissue volume of second-degree burn wounds. methods: this clinical trial was conducted on 30 patients with second-degree burns ad...

The effects of dietary supplementation of grape seed extract (GSE) and vitamin C on carcass characteristics, gut morphology and ileal microflora in broiler chickens exposed to chronic heat stress were examined. Experimental diets included a control diet (without additive), 3 levels of GSE (150, 300, 450 mg/kg of diet), and vitamin C (300 mg/kg of diet). Each of the five diets was fed to 5 repli...

Recent findings show that developmental vitamin D deficiency leads to altered brain morphology and behavioral development in the rat offspring. We examined the effects of different dietary vitamin D levels in rat dams on behavior and biochemistry of the offspring. Females were divided into five conditions and received diets containing 0, 1,5, 3.3, 6.0, or 10.0 IU/g of vitamin D₃ from mating to ...
