BACKGROUND The combination of the inhaled muscarinic antagonist umeclidinium (UMEC) with the long-acting β2-agonist vilanterol (VI) has been shown to provide significant improvements in lung function compared with UMEC, VI, or placebo (PBO) in patients with chronic obstructive pulmonary disease (COPD). This study was specifically designed to support these findings by assessing health-related qu...
چکیده هدف اصلی این پژوهش بررسی رابطه بین شایسته سالاری و عدالت سازمانی مدیران دانشگاه اصفهان و علوم پزشکی اصفهان بود که در قالب 5 فرضیه با در نظر گرفتن ابعاد شایسته سالاری و عدالت سازمانی مدیران دانشگاه اصفهان و علوم پزشکی انجام شد. روش پژوهش توصیفی از نوع همبستگی می باشد. جامعه آماری کلیه اعضای هیأت علمی و مدیران گروه در دانشگاه اصفهان و علوم پزشکی اصفهان به ترتیب 104- 645 – 33- 468 نفر در س...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
Research on healthy ageing lacks an agreed conceptual framework and has not adequately taken into account the growing evidence that social and biological factors from early life onwards affect later health. We conceptualise healthy ageing within a life-course framework, separating healthy biological ageing (in terms of optimal physical and cognitive functioning, delaying the onset of chronic di...
The cardioprotective effects of E-type prostaglandins (EPs) have been attributed to vasodilatation, inhibition of platelet and neutrophil function (EP(2) mediated), and an unknown "cytoprotective effect." We have hypothesized that selective activation of EP(3) receptors may cause cardioprotection. The prostanoid derivative ONO-AE-248 selectively binds to murine EP(3alpha) receptors expressed in...
multiple sclerosis (ms) is an inflammatory and autoimmune disease.ms is characterized by blood brain barrier breakdown, inflammation, axonal injury, degeneration of the myelin sheath and etc. a significant association between inflammation and degeneration of neurons is observed in the brain. also active ms lesions always associated with inflammation thus inflammation is a target for treatment o...
The cytotoxicity of 193 and 248 nm excimer laser radiation was compared to that produced by a germicidal lamp (predominantly 254 nm) using Chinese hamster ovary cells (CHO), and a human diploid fibroblast line, AG-1522A. Excimer laser radiation at 248 nm (3.5 X 10(2) w/m2) and germicidal radiation (5.3 X 10(-5) w/m2) caused toxicity in both cell lines, with the AG-1522A cells (D37 = 7-8 J/m2) b...
