Poor Motor Competence Affects Functional Capacities and Healthcare in Children and Adolescents with Obesity.

Background: From a young age, children learn different motor skills known as fundamental motor skills. The acquisition of these skills is crucial for the future development of context-tailored actions that could improve adherence to physical activity (PA) practice. Motor competence and function deficits have been associated with pediatric obesity.

A nonerythropoietic derivative of erythropoietin protects the myocardium from ischemia-reperfusion injury.

The cytokine erythropoietin (EPO) protects the heart from ischemic injury, in part by preventing apoptosis. However, EPO administration can also raise the hemoglobin concentration, which, by increasing oxygen delivery, confounds assignment of cause and effect. The availability of EPO analogs that do not bind to the dimeric EPO receptor and lack erythropoietic activity, e.

Mesoangioblasts, vessel-associated multipotent stem cells, repair the infarcted heart by multiple cellular mechanisms: a comparison with bone marrow progenitors, fibroblasts, and endothelial cells.

Objective: To test the potential of mesoangioblasts (Mabs) in reducing postischemic injury in comparison with bone marrow progenitor cells (BMPCs), fibroblasts (Fbs), and embryonic stem cell-derived endothelial cells (ECs), and to identify putative cellular protective mechanisms.

Methods And Results: Cells were injected percutaneously in the left ventricular (LV) chamber of C57BL/6 mice, 3 to 6 hours after coronary ligation, and detected in the hearts 2 days and 6 weeks later. Echocardiographic examinations were performed at 6 weeks.

Eplerenone, a selective aldosterone blocker, improves diastolic function in aged rats with small-to-moderate myocardial infarction.

Background: The incidence of cardiovascular diseases increases rapidly with age, and the elderly suffer higher morbidity and mortality. Aldosterone blockers have shown benefits in patients with left ventricular (LV) dysfunction and heart failure after myocardial infarction (MI). However, aldosterone blockade efficacy has not been explored in aged animals with MI.

Myocardial infarction: animal models.

Among the cardiovascular pathologies, ischemic heart disease is the leading cause of congestive heart failure as well as permanent premature disabilities. Reperfusion of a previously ischemic heart is a standard clinical procedure. Even if beneficial, reperfusion triggers an inflammatory response that contributes to the acute extension of ischemic injury and later participates in the reparative processes of the damaged myocardium.
