BACKGROUND In sedentary humans endothelium-dependent vasodilation is impaired with advancing age contributing to their increased cardiovascular risk, whereas endurance-trained adults demonstrate lower age-related risk. We determined the influence of regular aerobic exercise on the age-related decline in endothelium-dependent vasodilation. METHODS AND RESULTS In a cross-sectional study, 68 hea...

Background Regular exercises decrease the risk of various diseases. This is a reason to recommend exercises for health promotion. Thus American Heart Association (AHA) and American College of Sport Medicine (ACSM) have issued guidelines for young people resistance exercises. Aim: To investigate the effect of resistance training exercise on hematological, immunological and coagulation parameters...

The harmonic content of the envelope waveform of the blood flow velocity in the ophthalmic artery was analyzed in aging and arterial hypertension. The case-control study enrolled 98 healthy men (age: 44.0+/-15.6 years), 100 healthy women (age: 44.5+/-19.1 years), which is group 1, and overall 199 hypertensive patients with increased systolic and diastolic blood pressure (in millimeters of mercu...

Understanding sex differences in stress regulation has important implications for understanding basic physiological differences in the male and female brain and their impact on vulnerability to sex differences in chronic medical disorders associated with stress response circuitry. In this functional magnetic resonance imaging study, we demonstrated that significant sex differences in brain acti...

BACKGROUND Acute partial sleep deprivation increases plasma concentrations of ghrelin and decreases those of leptin. OBJECTIVE The objective was to observe modifications in energy intake and physical activity after acute partial sleep deprivation in healthy men. DESIGN Twelve men [age: 22 +/- 3 y; body mass index (in kg/m(2)): 22.30 +/- 1.83] completed a randomized 2-condition crossover stu...

Age is associated with substantial macrostructural brain changes. While some recent magnetic resonance imaging studies have reported larger age effects in men than women, others find no sex differences. As brain morphometry is a potentially important tool in diagnosis and monitoring of age-related neurological diseases, e.g., Alzheimer's disease (AD), it is important to know whether sex influen...

Ventilatory capacities of 73 Libyan men working in the Asbestos-Cement Pipe factory in Jenzur, a residential area near Tripoli, Libya and those of 73 age-matched healthy Libyan men unexposed to asbestos were determined. The mean values of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) for men unexposed to asbestos were 3.89 +/- 0.084 and 3.64 +/- 0.082 liters respec...

Age-related structural brain changes have been demonstrated repeatedly but data on the effect of gender on age-related structural brain changes are conflicting. Using high-resolution T1-weighted magnetic resonance imaging and voxel-based morphometry, we examined a population of 133 healthy adults (women, 73; men, 60; age range, 29-80 years) focusing on differential aging between men and women (...
