Effect of Tocotrienols enriched canola oil on glycemic control and oxidative status in patients with type 2 diabetes mellitus: A randomized double-blind placebo-controlled clinical trial.

Background: Tocotrienols have been shown to improve glycemic control and redox balance in an animal study, but their effects on patients with diabetes are unknown. The study aimed to investigate whether tocotrienols improves glycemic control, insulin sensitivity, and oxidative stress in individuals with type 2 diabetes mellitus (T2DM).

Materials And Methods: This study was a double-blinded, placebo-controlled, randomized trial.

The influence of calcium supplement on body composition, weight loss and insulin resistance in obese adults receiving low calorie diet.

Background: Obesity and diabetes are the most important problems of public health. Evidence from molecular animal research and epidemiologic investigations indicate that calcium intake may have an influence on body composition, weight and insulin resistance. The objective of this study was to determine the effects of calcium supplementation on body composition, weight, insulin resistance and blood pressure in the face of calorie restriction in obese adults.

Effect of crocus sativus on gentamicin induced nephrotoxicity.

Crocus sativus, known as saffron, is used in folk medicine for treatment of different types of diseases, and its anti-inflammatory and free radical scavenging activities have been demonstrated. The present study evaluated gentamicin nephrotoxicity in saffron treated rats. Male Wistar rats (200-250 g) were treated with saffron (40 or 80 mg/k/d) for 10 days, or saffron (40 or 80 mg/ kg/d) for 10 days and gentamicin 80 mg/kg/d for five days, starting from day 6.

Effect of vitamin C supplementation on oxidative stress and lipid profiles in hemodialysis patients.

Background And Aims: The increase in oxidative stress is the main factor in acceleration of atherosclerosis, leading to death in hemodialysis patients. Vitamin C is one of the most important antioxidants that inhibits lipid peroxidation and improves endothelial function. This study aims to assess the effects of vitamin C supplementation on lipid profiles as well as markers of lipid peroxidation among hemodialysis patients.

Development and validation of a short food-frequency questionnaire for screening women of childbearing age for vitamin A status in northwestern Iran.

A high percentage of women in their childbearing years suffer from subclinical vitamin A deficiency; 10% to 20% of pregnant women worldwide are vitamin A deficient. This study aimed to design and validate a short food-frequency questionnaire to serve as a simple screening tool for vitamin A status in women of childbearing age. The sample consisted of 187 healthy, nonpregnant, nonlactating women 15 to 49 years of age, from urban and rural areas of Marand district in East Azerbaijan.
