background: the removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. the removal of poisonous cr(vi) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study.  methods: fumed silica, bentonite (bn), hydrotalcite (ht), mcm-41, na-y, mordenite (mor) and sapo-34 were used at d...

background: hemorrhagic transformation (ht) of ischemic stroke (is) is a detrimental complication. this study investigated the association between serum ferritin level and ht in patients with massive is of middle cerebral artery.   methods: thirty patients with massive is of middle cerebral artery were enrolled in this prospective cohort study. they were divided into two groups based on the ser...

Context-sensitive half-times (CSHTs) of fentanyl in dogs were determined using pharmacokinetic models reported by Murphy et al. and Sano et al., and compared with a human model. The CSHT was defined as the time required for a 50% decrease in drug concentration in the central compartment after the termination of infusion. Although CSHTs increased gradually as the infusion time increased, the CSH...

The temperature-independent effects of electromagnetic fields (EMF) have been controversial for decades. Here, we critically analyze the available literature on non-thermal radiofrequency (RF) and microwave EMF. We present a review preclinical clinical data antiproliferative various EMF applications, including conventional RF hyperthermia (HT, cRF-HT). Further, suggest evaluate plausible biophy...

Introduction: The objective of this work was to investigate the therapeutic effect of a combination of hyperthermia at 43oC exposured for 20, 40, 60 min with 6MeV electron beams at different radiation doses (2, 4, 6 Gy) compared to radiation alone.   Materials and Methods: In this in vitro study, HeLa cells were exposed to either: 6MeV electron beams at diffe...

Methylenedioxymethamphetamine (MDMA) has previously been shown to produce a positive conditioned place preference (CPP) among rats. Here the effects of doses of a specific 5-HT3 antagonist, MDL72222, on MDMA's ability to produce a CPP were assessed. A dose of MDL72222 (0.03 mg/kg) blocked the establishment of a MDMA CPP. These results support the suggestions that compounds affecting the 5-HT3 r...

Background: Hemorrhagic Transformation (HT) of Ischemic Stroke (IS) is a detrimental complication. This study investigated the association between serum ferritin level and HT in patients with massive IS of middle cerebral artery.   Methods: Thirty patients with massive IS of middle cerebral artery were enrolled in this prospective cohort study. They were divided into two groups based on...
