β-Adrenergic receptor signaling in cardiac function and heart failure
INTRODUCTION Congestive heart failure (CHF) is a major public health problem. Nearly 5 million Americans are afflicted with CHF and about 550,000 new cases are diagnosed each year (1). CHF is a pathophysiological condition in which the heart is unable to pump enough blood to meet the metabolic needs of the body. It is the endpoint for several cardiovascular diseases including coronary artery di...
متن کاملEffects of preconditioning with intermittent normobaric hyperoxia on TNFR1 and TNFR2 expression in the rat brain
Introduction: Recent studies have shown that intermittent normobaric hyperoxia (HO) protects the rat brain from ischemia reperfusion injury. However, the exact mechanism of this kind of protection in vivo is not known. In this study, the effect of HO on expression of TNFR1 and TNFR2 in a stroke model was investigated. Methods: In this experimental study, rats were divided into 4 groups: no...
متن کاملChronic intermittent hypoxia increases infarction in the isolated rat heart.
Coronary heart disease is frequently associated with obstructive sleep apnea syndrome and treating obstructive sleep apnea appears to significantly improve the outcome in coronary heart disease. Thus we have developed a rat model of chronic intermittent hypoxia (IH) to study the influence of this condition on myocardial ischemia-reperfusion tolerance and on functional vascular reactivity. Wista...
متن کاملThe effects of nightly normobaric hypoxia and high intensity training under intermittent normobaric hypoxia on running economy and hemoglobin mass.
We investigated the effects of nightly intermittent exposure to hypoxia and of training during intermittent hypoxia on both erythropoiesis and running economy (RE), which is indicated by the oxygen cost during running at submaximal speeds. Twenty-five college long- and middle- distance runners [maximal oxygen uptake (Vo(2max)) 60.3 +/- 4.7 ml x kg(-1) x min(-1)] were randomly assigned to one of...
متن کامل.Neuroprotection induced by Preconditioning with Prolonged and Intermittent Normobaric Hyperoxia Induce Catalase Activity in the rat stroke model
Introduction: Ischemic preconditioning (IPC) is an endogenous phenomenon that can induce ischemic tolerance (IT) in variety of organs such as brain. In this study, we examined the intermittent and prolonged dose of normobaric hyperoxia (HO) on neurologic deficit scores, infarct volume, and catalase activity. Material and Method: The rats were divided to four main groups. First two main groups w...
