(Frontiers Media, 2018)Studies conducted in rodents subjected to chronic stress and some observations in humans after psychosocial stress, have allowed to establish a link between stress and the susceptibility to many complex diseases, including ...
-
(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 ...
-
Microsomal oxidative stress induced by NADPH is inhibited by nitrofurantoin redox biotranformation (Informa Healthcare, 2014)Nitrofurantoin is used in the antibacterial therapy of the urinary tract. This therapy is associated with various adverse eff ects whose mechanisms remain unclear. Diverse studies show that the nitro reductive metabolism ...
-
(BLACKWELL PUBLISHING, 2005-06)Activation of microsomal UDP-glucuronyltransferase (UDPGT) activity by treatment of hepatic microsomes with either detergents or Fe3+/ascorbate pro-oxidant system has been reported; however, definite mechanisms underlying ...
-
(SOC BIOLGIA CHILE, 2008)HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is characterized by axonal degeneration of the corticospinal tracts. The specific requirements for transport of proteins and organelles to the distal ...
-
(2009)An effective extraction method was devised for the determination of organophosphorus pesticides (OPPs) in olive and avocado oil samples, using atmospheric pressure microwave-assisted liquid-liquid extraction (APMAE) and ...
-
(ELSEVIER, 2006-09-25)A simple microwave-assisted extraction and partitioning method (MAEP) using water-acetonitrile and n-hexane for desorption and simultaneous partitioning, respectively, together with gas chromatography (GC) was studied to ...
-
(ROYAL SOC CHEMISTRY, 2003)A microwave-assisted solvent extraction (MASE) method for the determination of methabenzthiazuron (MBT) in soil samples by HPLC-DAD ( diode array detection) was evaluated. Spiked soil samples having different physico-chemical ...
