Cardioprotection by postconditioning in conscious rats is limited to coronary occlusions <45 min.
OBJECTIVES Brief episodes of ischemia and reperfusion after a lethal ischemic insult confer cardioprotection, a phenomenon termed "ischemic postconditioning." However, all studies reported to date have been conducted in open-chest animal models. We sought to determine whether postconditioning occurs in conscious animals and whether it protects against severe myocardial injury. METHODS Chronic...
متن کاملThe Response of Skeletal Muscle-Expressed Neurotrophins to Acute Resistance Exercise in Male Wistar Rats
Background. BDNF and NT-4/5 have been proposed to be involved in the coordinated adaptations of the neuromuscular system to the elevated level of activity, but an activity-dependent expression of neurotrophins in skeletal muscle is not well established. Objectives. We, therefore, investigated the effect of one session of resistance exercise on mRNA expression of some neurotrophins in Slow and ...
متن کاملTracheal occlusions evoke respiratory load compensation and neural activation in anesthetized rats.
Airway obstruction in animals leads to compensation and avoidance behavior and elicits respiratory mechanosensation. The pattern of respiratory load compensation and neural activation in response to intrinsic, transient, tracheal occlusions (ITTO) via an inflatable tracheal cuff are unknown. We hypothesized that ITTO would cause increased diaphragm activity, decreased breathing frequency, and a...
متن کاملWater drinking-related muscle contraction induces the pressor response via mechanoreceptors in conscious rats.
Water drinking is known to induce the pressor response. The efferent pathway in this response involves sympathoexcitation, because the pressor response was completely abolished by ganglionic blockade or an α(1)-adrenergic antagonist. However, the afferent pathway in this response has not been identified. In the present study, we hypothesized that water itself stimulates the upper digestive trac...
متن کاملChronic Intrinsic Transient Tracheal Occlusion Elicits Diaphragmatic Muscle Fiber Remodeling in Conscious Rodents
BACKGROUND Although the prevalence of inspiratory muscle strength training has increased in clinical medicine, its effect on diaphragm fiber remodeling is not well-understood and no relevant animal respiratory muscle strength training-rehabilitation experimental models exist. We tested the postulate that intrinsic transient tracheal occlusion (ITTO) conditioning in conscious animals would provi...
