Advances in Life Sciences

Advances in Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. All articles are rigorously reviewed. The journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms.
