Exercise preconditioning promotes myocardial GLUT4 translocation and induces autophagy to alleviate exhaustive exercise-induced myocardial injury in rats
Exercise preconditioning (EP) is a line of scientific inquiry into the short-term biochemical mediators of cardioprotection in the heart. This study examined the involvement of autophagy induced by energy meta...

Open AccessExercise preconditioning improves electrocardiographic signs of myocardial ischemic/hypoxic injury and malignant arrhythmias occurring after exhaustive exercise in rats
Exercise preconditioning (EP) has a good myocardial protective effect. This study explored whether EP improves electrocardiographic (ECG) signs of myocardial ischemic/hypoxic injury and the occurrence of malig...

Late Exercise Preconditioning Regulates BNP Increasing to Assist the Cardioprotection via Up-Regulation of NPR-A and Down-Regulation of NPR-C in Rat Myocardium
Late exercise preconditioning (LEP) is known to have a cardioprotection against myocardial injury induced by high-intensity exercise (HE). B-type natriuretic peptide (BNP) carries out the majority of its effec...

Comparison of myocardial ischemic/hypoxic staining techniques for evaluating the alleviation of exhaustive exercise-induced myocardial injury by exercise preconditioning
Exercise preconditioning (EP) can alleviate myocardial ischemic/hypoxic injury by inducing endogenous cardioprotection. Hematoxylin–eosin (HE), hematoxylin-basic fuchsin-picric acid (HBFP), and chromotrope-2R ...

Open AccessAltered expression levels of autophagy-associated proteins during exercise preconditioning indicate the involvement of autophagy in cardioprotection against exercise-induced myocardial injury
Exercise has been reported to induce autophagy. We hypothesized that exercise preconditioning (EP)-related autophagy in cardiomyocytes could be attributed to intermittent ischemia–hypoxia, allowing the heart t...

Cardioprotection of exercise preconditioning involving heat shock protein 70 and concurrent autophagy: a potential chaperone-assisted selective macroautophagy effect
It has been confirmed that exercise preconditioning (EP) has a protective effect on acute cardiovascular stress. However, how Hsp70 participates in EP-induced cardioprotection is unknown. EP may involve Hsp70 ...

Elevated C-type natriuretic peptide elicits exercise preconditioning-induced cardioprotection against myocardial injury probably via the up-regulation of NPR-B
To evaluate exercise preconditioning (EP)-induced cardioprotective effects against exercise-induced acute myocardial injury and investigate the alterations of C-type natriuretic peptide (CNP) and its specific ...

Stationary response of stochastically excited nonlinear systems with continuous-time Markov jump
An approximate method for predicting the stationary response of stochastically excited nonlinear systems with continuous-time Markov jump is proposed. By using the stochastic averaging method, the original sys...

Dynamics of a prey-predator system under Poisson white noise excitation
The classical Lotka-Volterra (LV) model is a well-known mathematical model for prey-predator ecosystems. In the present paper, the pulse-type version of stochastic LV model, in which the effect of a random nat...

Bioremediation potential of spirulina: toxicity and biosorption studies of lead
This study examines the possibility of using live spirulina to biologically remove aqueous lead of low concentration (below 50 mg/L) from wastewater. The spirulina cells were first immersed for seven days in f...
