The estrogenic activity of phthalate esters for dental use as plasticizers was concerned. To study the feasibility of candidate chemicals for phthalate tissue conditioners, three candidate plasticizers, di-n-butyl sebacate, acetyl tributyl citrate and tri-n-butyl phosphate together with conventional plasticizers were examined for estrogenic activity and cytotoxicity using three estrogenicity as...

background: previous studies reported that neonatal and maternal complications as well as duration of labor could be diminished through labor management. therefore, we aimed to evaluate the effect of intramuscular (im) administration of atropine and hyoscine combination on labor progress and maternal and neonatal outcomes in primigravid women admitted to taleghani hospital of arak, iran. method...

BACKGROUND Nonanesthetic colonoscopy is popular in clinical practice in China. However, intestinal spasms often result in a prolonged examination time, increased operating difficulties, decreased polyp detection rate, and failure to complete the procedure clinically. Therefore, exploring alternative approaches that can reduce the pain in patients during colonoscopy is of utmost importance, and ...

objective(s):green tea (gt) is one of the most popular beverages worldwide whose beneficial effects on health have been demonstrated. recent studies suggest that gt may contribute to reduction of cancer risk and progression. the aim of this study was to evaluate the effects of whole gt on urinary bladder chemical carcinogenesis in male and female icr mice. materials and methods: the gt characte...

addition of n-butyl nitrite to isolated rat hepatocytes caused an immediate glutathione depletion followed by an inhibition of mitochondrial respiration, inhi- bition of glycolysis and atp depletion. at cytotoxic butyl nitrite concentrations, lipid  peroxidation  occurred  before  the  plasma  membrane  was  disrupted. cytochrome p-450 inhibitors inhibited peroxynitrite formation and prevented ...

The title compound, C(16)H(23)NO(4), is essentially planar except for the last two C atoms in each n-butyl group (r.m.s. deviation from the least-squares plane = 0.02 Å for 17 non-H atoms). In the crystal, inter-molecular N-H⋯O hydrogen bonds between the amine and carbonyl groups link the mol-ecules into one-dimensional chains.

Buprenorphine 0.3 mg and papaveretum 20 mg, both combined with hyoscine 0.4 mg, were used as premedicants in female patients undergoing laparoscopy or abdominal hysterectomy. The effects were compared. It was found that the increase in drowsiness and tranquility was greater following buprenorphine than that following papaveretum. A low frequency of nausea was reported in the buprenorphine-hyosc...
