Acetaminophen induced renal injury via oxidative stress and TNF-alpha production: Therapeutic potential of arjunolic acid
(ELSEVIER IRELAND, 2010-01-31)Acetaminophen (APAP) causes acute and chronic renal failure. The mechanisms leading to hepatic injury have been extensively studied, but the molecular mechanisms regarding APAP-induced nephro-toxicity are poorly defined. ... -
Plant response to alternative matrices for in vitro root induction
(ACADEMIC JOURNALS, 2009-07-06)The quest for alternative matrices for plant tissue culture is a continuing process. This inquiry has two aspects. One being commercial for low cost tissue culture, and the other obviously is the better root induction ... -
