Skin aging is a biological process that is due to the reduction of collagen production and increase of multiple enzymes, including matrix metalloproteinase (MMPS), which degrade collagen. Chlorella vulgaris is a marine microalga and its beneficial effects on the skin make it a proper ingredient to be used in anti-aging products. In this study, the effect of C. vulgaris extract comparing to vita...
The aim of this study was to determine the acute and chronic toxicity of Deltamethrin insecticides and its effect on the activity of brain acetylcholinesterase and serum catalase enzymes and gill and liver tissues of Carassius auratus in the presence of vitamin C. In the acute toxicity test, LC50 of Deltamethrin was calculated by Probit test analysis and the effect of its chronic concentration ...
a sensitive procedure for determining total vitamin c (ascorbic acid + dehydrate ascorbic acid) in a blood drop from a finger prick, before and after the adminis- tration of a vitamin c tablet is described. analysis was carried out by high per- formance liquid chromatography with electrochemical detection (hplc/ec). measurements were taken one hour, two hours and six hours after the administr...
rabbits are widely used as laboratory animals for experimental surgery. anesthesia of rabbits may present complications unless the method is easy to apply and safe to use. in present study, effects of different dosages of vitamin c on thiopental sodium induced anesthesia in 25 male new zealand white rabbits were studied. in the animals that had not received vitamin c treatment before thiopental...
Humans use two sodium-ascorbate cotransporters (hSVCT1 and hSVCT2) for transporting the dietary essential micronutrient ascorbic acid, the reduced and active form of vitamin C. Although the human liver plays a pivotal role in regulating and maintaining vitamin C homeostasis, vitamin C transport physiology and regulation of the hSVCT systems in this organ have not been well defined. Thus, this r...
