ischemia reperfusion injury (ir injury) is a common problem in clinical conditions. researches have frequently revealed that atp- sensitive potassium (katp) channels and nitric oxide plays a role in protection against ischemic injury in skeletal muscle. the present study aimed at evaluating the possible link between this two pathways. sixty-eight male wistar rats, were pretreated with saline, d...

Background: The number of patients with Multiple Sclerosis (MS) is increasing in Iran. Studies have shown that high sodium chloride (salt) and low potassium intake are associated with the development of MS. High physiological salt concentrations can lead to the induction of Interleukin-17 (IL-17) accompanied by the excessive generation of helper T-17 cells (Th-17). This cytokine plays a critica...

background and objectives:  helicobacter pylori cause a chronic gastric infection, and may cause extra gastrointestinal disease. the association between h. pylori infection and serum lipid profiles is still controversial. the aim of this study was to investigate any possible relationship between h. pylori infection and lipid levels. materials and methods: the subjects were 400 volunteer referr...

OBJECTIVES The purpose of this study was to evaluate the impact of door-to-balloon time with primary percutaneous coronary intervention (PCI) on late cardiac mortality. BACKGROUND The impact of door-to-balloon time on outcomes is controversial, and the impact on late mortality has not been studied. METHODS Consecutive patients (n = 2,322) treated with primary PCI from 1984 to 2003 were pros...

s of papers 41 (H=79.9 vs. I=81.0 eggs), and M (H=5.4 vs. I=20.9%). Also, strain effected (p<.001) bone BS (H=14.26 vs. I=12.26 kg) and volume (H=5.90 vs. I=6.27 cc). These results indicate that strain influences performance and bone parameters and suggest that increased Ca and P levels impact bones of laying hens only if provided during the rearing phase.

Background Infant respiratory distress syndrome (IRDS) is one of the main causes of serious complications and death in preterm infants. Both Nasal Continuous Positive Airway Pressure (NCPAP) and Nasal Intermittent Positive Pressure Ventilation (NIPPV) are known as the most common treatment strategies for IRDS. The present study intended to compare NCPAP and NIPPV in the treatment of preterm inf...

background: it is clear that helicobacter pylori (h. pylori) is a spiral bacterium that infects human and causes gastritis and peptic ulcer. the aim of this study was to determine the relationship between h .pylori infection and the iron status of the body. methods: this study was conducted in shahid beheshti hospital of babol university of medical sciences, babol, iran from august 2007 to july...
