Seventeen volunteer male professional cyclists were randomly assigned to control or supplemented (6 g L-citrulline-malate) groups and participated in a cycling stage. Blood samples taken basal conditions, after the race 3 h post-race. Citrulline supplementation significantly increased plasma concentration of both arginine citrulline stage only group. Polymorphonuclear neutrophils (PMNs) from controls responded exercise with progressive decrease ROS production. Supplemented PMNs production...

Abbreviated progressive muscle relaxation (APMR) is a much used stress-management technique. Its efficacy relevant to placebo control already established in the literature and primary aim of present study was ascertain whether its proven impact on psychological stress measures matched by decrease prevailing levels stress-associated hormone cortisol, using accurate robust measurement based multiple sampling full diurnal cortisol secretion profiles. First-year university students can face...

Introducción: En el año 2020, la Organización Mundial de Salud (OMS) declaró pandemia a enfermedad por coronavirus (COVID-19). SARS-COV-2 genera compromiso predominantemente pulmonar, aunque también se ha observado una infección sistémica que afecta sistema hematopoyético y coagulación. A pesar los notables avances en su comprensión, virus continúa activo resulta gran interés práctico contar con parámetros biológicos permitan alertarnos sobre posible evolución desfavorable.Metodología:...

Evidence suggests that personality traits may play a significant role in individual differences cortisol reactivity stressful situations. In this study, responses to public speaking were examined test hypotheses would be positively related openness, agreeableness, and conscientiousness, negatively extraversion, neuroticism, psychoticism, respectively. A sample of 75 students (56 women 19 men) completed the NEO Five-Factor Inventory (Costa & McCrae, 1992) Eysenck Personality...

<i>Background:</i> Cardiovascular (CV) diseases are a leading cause of mortality and they frequent in patients with the obstructive sleep apnea syndrome (OSAS). <i>Objectives:</i> In this study we investigated if OSAS influences CV function independently other risk factors frequently present these (e.g. obesity, high blood pressure). <i>Methods:</i> We compared plasma markers endothelial dysfunction, asymmetric dimethylarginine (ADMA) endothelin-1 (ET-1),...

Summary There is evidence that changes in branched‐chain amino acid ( BCAA ) levels may correlate with the efficacy of therapeutic interventions for affecting improvement metabolic control. The objective this study was to evaluate whether serum concentrations s (leucine, isoleucine, valine) could mediate insulin sensitivity and glucose tolerance after continuous positive airway pressure CPAP treatment patients obstructive sleep apnea OSA ). A prospective randomized controlled trial morbid...

The effects of obstructive sleep apnea (OSA) on the metabolic system are not well understood, especially in children. Recent studies have provided evidence modulation insulin action by branched-chain amino acids (BCAAs) and suggested novel mechanistic relationships between glucose acid pathways. We hypothesized that plasma BCAA levels may serve as biomarkers resistance dysfunction children with OSA.A polysomnography was conducted for diagnosis OSA 90 snoring children, a tertiary hospital....

Introduction Venous thromboembolism (VTE) is a serious, frequent, and preventable medical complication in hospitalized patients. Although the efficacy of prophylaxis (pharmacological and/or mechanical) has been demonstrated, compliance with poor at international national levels. Aim To determine indication use pharmacological thromboprophylaxis patients Uruguay. Methods An observational, descriptive, cross-sectional, multicentre study involving 31 nationwide healthcare facilities was...
