Radical Tails: Antioxidants Can Prevent Regeneration

Posted 14 January 2013 by Jalees Rehman

Amphibians such as frogs or salamanders have a remarkable ability to regenerate amputated limbs and tails. The regenerative process involves the formation of endogenous pluripotent stem cells, which then expand and differentiate into the tissue types that give rise to the regenerated body part. The complex interplay of the cell types and signals involved in this regenerative response to the injury are not fully known and there is considerable interest in identifying all the necessary steps. The ultimate hope is... Read more

The Healing Power of Sweat Glands

Posted 20 November 2012 by Jalees Rehman

Two kinds of sweat glands are present in the human body. Apocrine sweat glands are located in arm-pits or rectogenital areas and are responsible for "smelly" sweat. Eccrine sweat glands, on the other hand, are distributed all over the human body and produce a non-odorous sweat. The eccrine sweat glands are primarily found in humans and certain primates. They also exist in some other mammals, but are usually restricted to the footpads of non-primate mammals. There is some controversy about... Read more
