Objectives: Vascular endothelial cells play an important role in the regulation of vascular vessels with active substances, such as vascular endothelial growth factor are responsible. The present study tried to investigate the effect of resistance training on the density of old women’s endothelial growth factor. Methods & Materials: Twenty-four postmenopausal women (age Mean&...
Introduction: Stumbling or falling is a major health problem among the elderly which accounts for their majority of physical injuries such as pelvic fractures, disability, loss of independency and even death. The goal of the study was comparison of the effect of aerobic and resistance exercise on static and dynamic balance in old men. Methods: A quasi-experimental study was conducted and t...
Purpose: To study the benefits of Directional Bremsstrahlung Splitting (DBS) dose variance reduction technique in BEAMnrc Monte Carlo (MC) code for Oncor® linac at 6MV and 18MV energies. Materials and Method: A MC model of Oncor® linac was built using BEAMnrc MC Code and verified by the measured data for 6MV and 18MV energies of various field sizes. Then Oncor® machine was modele...
Background and Objective: Renal transplantation is an efficient solution for end-stage renal disease patients. Since the purpose of treatment of renal failure patients is not only to sustain life, but also to improve the quality of life, this study investigated the quality of life in transplanted patients and affecting factors. Materials and Methods: This cross-sectional study was cond...
Introduction: The selection of porcelain is based on high biocompatibility, endurance, superficial texture and aesthetics. Nevertheless, the innate fracture charateritics of porcelain is the main cause of the intra oral fractures. Electing a suitable porcelain restorative system in terms of stability of color is important. For this reason, this study aimed to examine the color changes of common...

Exercise-induced muscle oxidative stress may be involved in the myopathy associated with chronic obstructive pulmonary disease (COPD). This study was designed to look at whether local exercise induces muscle oxidative stress and whether this may be associated with the reduced muscle endurance in COPD. Quadriceps endurance was measured in 12 patients with COPD (FEV1 = 0.96 [[plusmn]] 0.14 SEM) a...
