Objective(s): Stress is a physiological response that can disrupt body elements homeostasis and lead to neurophysiological abnormality. This study has been investigated the serum and hippocampus Mg2+, Zn2+, Fe2+/3+ and Ca2+ level changes in two times after MgO NPs and ZnO NPs single injection following restraint stress in the male rat. Methods: Animals were divided into two main groups that eac...

Evidence suggests that neuropeptide Y (NPY) and agouti-related protein (AgRP) in the arcuate nucleus (ARC) are modulated by glucoregulatory hormones and involved in maintaining normal eating patterns and glucose homeostasis in states of energy deficiency. This study investigated whether these peptides respond to glucose itself under conditions, e.g., before the nocturnal feeding cycle, when car...

BACKGROUND AND OBJECTIVES Characterizing relationships of kidney function to healthcare costs in polycystic kidney disease has applications for economic evaluations of standard and emerging therapies. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The administrative records (2003 to 2006) of a private health insurer were examined to identify polycystic kidney disease patients (n = 1913) from I...

BACKGROUND Carbon dioxide pneumoperitoneum induces peritoneal oxidative stress. The aim of this study was to verify the effect of intra-abdominal pressure on oxidative stress in the peritoneum and on post-operative adhesion formation. METHODS Forty-one rabbits underwent laparoscopic surgery: either gasless, or with CO(2)-pneumoperitoneum at pressures of 5, 10 or 15 mmHg. Serial parietal perit...

In vitro studies with the Diskus inhaler at low and high flow rates show consistent doses of drug as fine particles <4.7 microm. The present study was designed to ascertain whether this in vitro flow independency translates into flow-independent clinical effect when the device is used by patients at low (30 L x min[-1]) and high (90 L x min[-1]) flow rates. A pilot study in 129 children aged 3-...

The volatile anesthetic sevoflurane is capable of inducing preconditioning and postconditioning effects in the brain. In this study, we investigated the effects of sevoflurane postconditioning on antioxidant and immunity indexes in cerebral ischemia reperfusion (CIR) rats. Rats were randomly assigned to five separate experimental groups I-V. In the sham group (I), rats were subjected to the sam...

The numerical density of GABA immunopositive and GABA immunonegative neurons was quantitatively determined in 0, 12, 30 and 90 day-old neocortical transplants, derived from E17 rat embryos and transplanted into adult hosts. It was found that the original, very high neuronal density in the fetal transplant declined steadily after transplantation to the somatosensory cortex of adult rat. The decl...

PURPOSE Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF) widely used in clinical oncology. Bevacizumab is commonly co-adminis- tered with chemotherapy. It is recommended that the first infusion of the antibody last 90 min, the second 60 and all subsequent 30 min. Since there is no clear rationale for the proposed schedule of administration, our study assess...

BACKGROUND The authors sought to assess the effect of acute smoking on gastric contents in regular smoker volunteers. The primary endpoint was the variation in antral area during the 120-min study period after cigarette smoking. METHODS Regular smoker volunteers were included in this prospective randomized single blind cross-over study. Volunteers attended two separate study sessions: Control...

INTRODUCTION Since strenuous exercise for 10 min during preoxygenation was shown to provide better protection from decompression sickness (DCS) incidence than resting preoxygenation, a logical question was: would a longer period of strenuous exercise improve protection even further? HYPOTHESIS Increased strenuous exercise duration during preoxygenation increases DCS protection. METHODS Ther...
