Previous animal studies had shown that increasing heat shock protein 70 (Hsp70) using a transgenic, gene therapy or pharmacological approach provided cardiac protection in models of acute cardiac stress. Furthermore, clinical studies had reported associations between Hsp70 levels and protection against atrial fibrillation (AF). AF is the most common cardiac arrhythmia presenting in cardiology c...

this book has three chapters: heart, lung and radiation protection. in each chapter, indications of scans, radiopharaceuticals the study performance, patient preparation, report and also possible problems were discussed. in addition, in the end of each chapter, many mutliplechoice question (mca) were expressed. the studying of this book for at medical students, physicians and colleagues is reco...

BACKGROUND AND OBJECTIVES Myocardial protection defines the set of strategies aiming at attenuating the intensity of myocardial ischemia-reperfusion injury during heart surgery and its harmful consequences on myocardial function. A better understanding of pathophysiological phenomena related to ischemia-reperfusion events and of the anesthetic-induced heart protection has given to the anesthesi...

polyunsaturated fatty acids (pufas) particularly ω-3 pufas showed great assure in prevention of cardiovascular diseases (cvd). the evidence for cv benefits of pufa comes from eicosapentaenoic acid (epa) with or without docosahexaenoic acid (dha) in primary prevention, after myocardial infarction (mi), with heart failure (hf). the epidemiologic studies and trials showing the benefits of pufa, sp...

background: despite the widespread use of respiratory protection equipment in different jobs, the effects of these devices on people’s physiological responses are not well recognized as yet. therefore, the aim of this study is to evaluate the effect of the air purifying respiratory protection equipment on the heart rate. methods: this experimental study was performed in a climate chamber under ...
