The reduction of 1,1-diaryl-2,2-dicyanoethylenes with SmI(2) in THF was studied in the presence of four proton donors: H(2)O, MeOH, i-PrOH and trifluoroethanol (TFE). The kinetic order for the first two is nearly unity at low proton donor concentrations and approaches four at high concentrations, whereas, for i-PrOH and TFE, the log-log plot is linear with a slope smaller than one. Detailed ana...

The corrosion inhibition potential and efficacy of 2-hydropyrimidine-2-thione derivative on mildsteel in 0.5 M sulfuric acid solution was investigated using electrochemical polarization and FTIRspectroscopic techniques. In addition, docking studies were carried out as theoretical investigationof adsorption inhibitor on iron surface. The results of polarization studies indicate...

background : to determine the role of letrozole, an aromatase inhibitor,in the treatment of endometriotic pain.   methods: in this prospective, randomized, controlled clinical trial in minimallyinvasive surgery research center,51 women with pelvic endometriosis and endometriotic pain (dyspareunia, dysmenorrhea, pelvic pain) score of 5 or more (for at least one of these endometriotic pain), afte...

angioedema is an asymmetric non-pitting oedema on face, lips, tongue and mucous membranes; any delay in diagnosis and treatment can be fatal. treatment with lisinopril as an angiotensin converting enzyme (ace) inhibitor, can be a reason of angioedema. here we report a case who developed oral-facial edema four years after using lisinopril/hydrochlorothiazide. laryngeal oedema is a main cause of ...
