there is no randomized study carried out in order to compare their pharmacokinetic parameters although midazolam, as a sedative, has been widely administered via continuous infusion as well as intermittent bolus doses in mechanically ventilated critically ill patients. we prospectively investigated the effect of these two principal methods on pharmacokinetic parameters in 23 of mentioned patien...

background: a substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. materials and methods: radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...

Background: Sarcocystosis is one of the most distributed parasitic diseases over the world, caused by Sarcocystis spp. In this study, we assessed the effect of electron beam irradiation on the viability of Sarcocystis spp. in beef.  Methods: Experimental beef groups were irradiated by four different electron beam doses of 1, 2, 3, and 4 kGy, at intervals of 0 and 24 h after irradiation, then t...

introduction: nowadays, spermatogonial stem cells (sscs) cultivation has been used by many researchers as an effective tool for infertility treatments. oxidative conditions can be effective on cell proliferation and differentiation of these cells. so, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during sscs in vitro culture. ...

Cadmium (Cd) accumulation in durum wheat (Triticum L.) is of particular concern compared to the other commonly cultivated cereals. This study was conducted determine effects zinc (Zn) and nitrogen (N) applications on grain Cd concentration grown a contaminated soil. The experimental design consisted randomized plots with four replications. treatments included low adequate (0.05 5 mg kg−1) Zn do...

Letrozole, an aromatase inhibitor, has been demonstrated to be effective as an ovulation induction and controlled ovarian hyperstimulation agent. However, dose administration has generally been limited to 5 days at 2.5 to 7.5 mg daily. We undertook a retrospective review of over 900 treatment cycles using letrozole in doses as high as 12.5 mg per day. Results indicate that such doses do indeed ...

Clinical trials of Ivermectin in single oral doses of 200, 400, and 1,000 mg/kg body weight or in multiple doses of 200 mg/kg body weight for 5 consecutive days were performed in leaf monkeys (Presbytis cristatus) infected with Wuchereria kalimantani. Optimal microfilaricidal effect occurred at 200 mg/kg body weight. The drug was less effective than diethylcarbamazine in this animal model for h...
