background previous studies have mostly focused on socio-demographic and health-related determinants of health-related behaviors. although comprehensive health insurance coverage could discourage individual lifestyle improvement due to the ex-ante moral hazard problem, few studies have examined such effects. this study examines the association of a comprehensive set of factors including socio-d...

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-...

Background: During the aging process, muscle atrophy and neuromuscular junction remodeling are inevitable. The present study aimed to clarify whether low-intensity aerobic exercise along with limb blood-flow restriction (BFR) could improve aging-induced muscle atrophy and nicotinic acetylcholine receptors (nAChRs) at the neuromuscular junction.Methods: Forty-eight male Wistar rats, aged 23–24 m...

background: to evaluate the effect of exendine-4 (ex-4), a glucagon-like peptide 1 (glp-1) receptor agonist, on the differentiation of insulin-secreting cells (ipcs) from rat adipose-derived mesenchymal stem cells(admscs). materials and methods: in this experimental study, admscs were isolated from rat adipose tissue and exposed to induction media with or without ex-4. after induction, the exis...

basic paradigm that computer programs employ is known as “search and evaluate.” Their static evaluation is arguably more primitive than the perceptual one of humans. Yet the intelligence emerging from them is phenomenal. A human spectator cannot tell the difference between a brilliant computer game and one played by Kasparov. Chess played by today’s machines looks extraordinary, full of imagina...

The relationship between games and learning has, predominantly, either treated games as potential educational content or only considered the social contexts of learning from games at a general level. A methodology has been developed that permits the detailed analysis of how people learn from particular instances of game play. This is used to study two approaches to playing Deus Ex, one involvin...

22 AI MAGAZINE Artificial intelligence (AI) is one of the most ambitious scientific and engineering adventures of all time. The ultimate goal is to understand the mind from a new perspective, and to create AIs1 capable of learning and applying intelligence to a wide variety of tasks: some as robots able to take action in our physical and social world, and some as software agents that make decis...

in the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities, because such discoveries can be easily imitated. two failures of the laissez – faire outcome are being highlighted: there is too little investment and entrepreneurship ex ante, and too much production diversi-fication ex post. optimal policy ...

Introduction: Renal ischemia/reperfusion (I/R) injury due to reactive oxygen species (ROS) formation is the main cause of acute kidney damage. Nitric oxide (NO) biosynthesis and oxidative stress are closely related to the pathogenesis of renal I/R injury. This study was undertaken to determine the effects of L-arginine (L-arg) as NO donor and aerobic exercise (EX) and also the combination of L-...

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...
