Investigations in these and other laboratories have estab lished that administration of 2(3)-tert-butyl-4-hydroxyanisole (BHA) to rodents: (a) protects a variety of target tissues against the production of tumors by a wide range of chemical carcin ogens; (b) reduces the levels of mutagenic metabolites pro duced from benzo(a)pyrene and numerous therapeutic agents in viva; (c) elevates the hepati...

In this study, ethanol extract of Carthamustinctoriuswas studied for superoxide anion scavenging activity. The antioxidant properties of Carthamustinctorius ethanol extract was evaluated using superoxide anion radical scavenging activities. The extract of Carthamustinctorius exhibited strong total antioxidant activity and superoxide anion scavenging activity. This antioxidant activity test were...

Effects of feeding mice and rats with 2(3)-tert-butyl-4-hydroxyanisole (BHA) and 3,5-di-tert-butyl-4-hydroxytoluene (BHT), the two most commonly used food-additive phenolic antioxidants with known anticarcinogenic properties but with only minor differences in their chemical structures, have been compared to search for common effects between the two agents in two different rodent species and the...

RATIONALE Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infection in children. No treatment has been shown to significantly improve the clinical outcome of patients with this infection. Recent evidence suggests that oxidative stress could play an important role in the pathogenesis of acute and chronic lung inflammatory diseases. We do not known whether RSV induce...

Abstract Background In our institute, all elderly patients with displaced femoral neck fracture were treated cemented bipolar hemiarthroplasty (BHA) using the modified Dall approach. To knowledge, there are no reports on knot position of greater trochanter reattachment. The aim this study was to determine influence two positions (anterior or posterior) complications trochanter. Methods This is ...

The Cananéia-Iguape estuarine–lagoon complex (São Paulo state, Brazil) is a natural laboratory to study metal binding by humic substances (HS) in subtropical settings. This transitional environment evolving into freshwater due water input from the Ribeira River, funneled through Valo Grande Canal (Iguape). Past mining activities River basin and maritime traffic are suspected be potential source...
