natural citrus biotypes are a valuable genetic resource in the country. investigation about diversity of biochemical compounds due to optimize the utilization and development of new varieties is useful. therefore, for identifying them, the fruits of 16 biotypes with numbers of 6, 8, 15, 21, 24, 25, 26, 29, 30, 41, 43, 45, 48, 51, 52 and 53 in the germplasm collection of the iran citrus research...
Processed fruits and vegetables have been long considered to have lower nutritional value than their fresh commodities due to the loss of vitamin C during processing. This research group found vitamin C in apples contributed < 0.4% of total antioxidant activity, indicating most of the activity comes from the natural combination of phytochemicals. This suggests that processed fruits and vegetabl...
Ceramide is the most abundant lipid in the epidermis and plays a critical role in maintaining epidermal barrier function. Overall ceramide content in keratinocyte increases in parallel with differentiation, which is initiated by supplementation of calcium and/or vitamin C. However, the role of metabolic enzymes responsible for ceramide generation in response to vitamin C is still unclear. Here,...
Since no reliable functional markers of human vitamin C status have been demonstrated, de termination of vitamin C levels in blood plasma and/ or leukocytes remains the current choice for individual and population assessments. Newer analytical tech niques, especially high-performance liquid chromatography, allow determination of reduced (ascorbic acid), oxidized (dehydroascorbic acid), or total...
The vitamin C content of human milk was determined among twenty-six newly delivered mothers. Milk samples (colostrum, transitional and mature) were obtained at different stages of lactation. Mean vitamin C concentration varied from 3.52 ± 0.56 mg/dl for colostrum to 3.03 ± 0.67 mg/dl for mature milk with the advancement of time, but was in agreement with the infant's daily requirement. Serum vi...
Background and Aim: Organophosphate insecticides such as diazinon (DZN) can disrupt the body's antioxidant defense system. Antioxidants protect cells against oxidative stress. In the present study, antioxidant properties of N- acetylcysteine (NAC) and vitamins E and C in reducing oxidative stress caused by DZN in rat spleen were compared. Materials and Methods: In this experimental study,...
