(2006)A high-performance liquid chromatography (HPLC) method for the determination of 2-(4-(N,N,N-trimethyl)-butyl)-5-dodecylfuryl bromide (DFTA) in dipalmitoylphophatidil-choline (DPPC) liposome solutions has been developed. ...
-
(PERGAMON-ELSEVIER SCIENCE LTD., 2011-10)Adverse reactions of acetaminophen have been associated to oxidative stress, which may be elicited by reactive oxygen species (ROS) and/or production of the metabolite NAPQI. Both phenomena would arise through the activity ...
