Ameliorative effect of Vitis vinifera (Linn.) seed extract on lead acetate induced oxidative damage on testis and sperm quality in Wistar rats.

Lead is considered one of the most prevalent environmental and biologically hazardous toxicants among metallic elements. It severely affects human health and especially the male reproductive system by causing reproductive organ dysfunction leading to infertility. Natural dietary antioxidants are studied for their ability to ameliorate the cells' miscellaneous damage.

Performance evaluation of pattern recognition networks using electromyography signal and time-domain features for the classification of hand gestures.

The problem of classifying individual finger movements of one hand is focused in this article. The input electromyography signal is processed and eight time-domain features are extracted for classifying hand gestures. The classified finger movements are thumb, middle, index, little, ring, hand close, thumb index, thumb ring, thumb little and thumb middle and the hand grasps are palmar class, spherical class, hook class, cylindrical class, tip class and lateral class.
