Computerized dynamic pupillometry as a screening tool for evaluation of autonomic activity.

Objectives: Dynamic pupillometry is a simple screening tool for quantifying pupillary light reflex (PLR), to indicate autonomic nervous system (ANS) activity. Heart rate variability (HRV) is the gold standard method for assessing ANS effects on the heart. The present study aimed to compare ANS activity as measured using dynamic pupillometry (DP) with short term HRV in healthy volunteers.

Vitamin d deficiency and insulin resistance in normal and type 2 diabetes subjects.

Vitamin D is recognized to serve a wide range of biological functions. The presence of vitamin D receptors on different tissues explains it's diversity of actions. Reduced levels of vitamin D is associated with insulin resistance and increased diabetes risk.
