Abstract Study question Is there an association between advancing male age and worsening seminal parameters (If so, is it possible to define age-threshold for semen quality decline)? Summary answer Only sperm morphology motility-related exhibited a significant negative with age, particularly from the of 40 years. What known already While importance advanced maternal on reduced fertility higher ...

Chronic two-kidney, one clip (2K1C) renovascular hypertension is characterized by a largely angiotensin-independent elevated blood pressure (BP). We hypothesized that the long-term effect of hypertension would compromise endothelium-derived nitric oxide (NO) and diminish its influence in controlling renal perfusion. We determined the influence of endothelium-derived NO on renal hemodynamics and...

Central and peripheral cardiovascular adaptations to 12 weeks of intense swim training were characterized in 12 previously sedentary middle-aged men and women. Peak oxygen uptake (VO2) during upright bicycle exercise improved from 29.2 +/- 5.6 to 34.7 +/- 6.7 ml/kg/min (mean +/- SD, p less than .01) because of similar increases in peak cardiac output (CO) and calculated arteriovenous oxygen dif...

were analysed for wet and dry weight, total lipid, total, free and esterified cholesterol, total carboxyl ester, lipid phosphorus and triglyceride. The translocated testes decreased in wet and dry weight (P<0\m=.\001) and total lipid content (P< 0\m=.\001)6 days after surgery. Lipid concentration increased (P<0\m=.\01)in translocated testes, as did concentrations of total cholesterol (P<0\m=.\0...

Abstract Introduction It has been documented that newborn’s sleep is strongly associated with maternal and paternal sleep. However, mothers seem to be more affected by their infant’s than fathers. These associations are not well known in families of premature newborns yet. This was the objective present study. Methods 30 (mothers, fathers infants) participated this study one month after dischar...

Background Analyzing actigraphy data using standard circadian parametric models and aggregated nonparametric indices may obscure temporal information that be a hallmark of the impairment in psychiatric disorders. Functional analysis (FDA) overcome such limitations by fully exploiting richness revealing important relationships with mental health outcomes. To our knowledge, no studies have extens...

BACKGROUND Despite their potential advantages, new coronary angioplasty devices may be associated with more frequent vascular complications than noted after standard balloon angioplasty, theoretically due to the larger sheaths and prolonged periods of anticoagulation required by some of these devices. This study sought to identify the incidence, predictors, and clinical outcome of vascular comp...

UNLABELLED Little is known about the relationship between attitudes and characteristics of instructors and uptake and adherence of older people to exercise classes. This article explores these issues. METHODS The authors surveyed 731 UK exercise instructors with specialist older adult exercise qualifications. A questionnaire investigated instructors' characteristics and attitudes toward older...
