Introduction: The aim of the present study was to evaluate the effect of exercise training and L-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (MI). Methods: Four weeks after the surgically-induced MI, 40 male Wistar rats were randomly assigned to the following 4 groups (n=10): MI-sedentary control (Sed) MI-exercise (Ex) MI-...

Neurotrophins are a group of nerve growth factors with their protein structure. These proteins play an important role in the growth and metabolism of many cells and maintain nerve, muscle, synaptic potentials, and also helps reduce depression and apoptosis. The aim of this study was to evaluate the effect of 10 weeks low-intensity aerobic training and limited blood flow to the amount of protein...

We show which implicational relations hold between the three principles ex falso sequitur quodlibet, tertium non datur, and double negation elimination, on the basis of minimal logic.

This paper aims to analyze and depict urban equilibrium from the perspective of a complex force field between (positive) agglomeration economies and (negative) environmental externalities. Based on a simplified representation of a linear urban economy, an archetypical model based on general equilibrium principles is designed and its properties are investigated by using numerical simulations.
