The effect of acute administration of vitamin D on micro vascular endothelial function in Caucasians and South Asian Indians.

Background: Vitamin D is a modulator of the immune system. There is some limited evidence that it also increases local blood flow in response to stress.

Material And Methods: In the present study, we examined 20 age matched subjects; 10 whom were from India and 10 Caucasians from the United States.

What is more damaging to vascular endothelial function: Diabetes, age, high BMI, or all of the above?

Background: It is well established that there is a reduction in the skin blood flow (SBF) in response to heat with age and diabetes. While it is known that high BMI creates a stress on the cardiovascular system and increases the risk of all cause of morbidity and mortality, little is known of the effect of high BMI on SBF response to heat. Since diabetes is associated with age and a higher BMI, the interrelationship between age, BMI and SBF needs to be investigated to better understand the contribution diabetes alone has to endothelial impairment.

Electroencephalography to assess motor control during balance tasks in people with diabetes.

Background: Balance is sensed through peripheral and central receptors and mediated by central control through the brain and spinal cord. Although some evidence exists as to the areas of the brain involved and how processing of data occurs in young individuals, nothing has been published on people with diabetes. The purpose of this study was to examine the electroencephalogram (EEG) during common sensorimotor and balance training tasks and to relate these to task difficulty.
