BACKGROUND Sexual dysfunction is common in patients with end stage renal disease (ESRD) and treatment options are limited. Observational studies suggest that nocturnal hemodialysis may improve sexual function. We compared sexual activity and responses to sexual related questions in the Kidney Disease Quality of Life Short Form questionnaire among patients randomized to frequent nocturnal or thr...

Most vertebrate groups exhibit eye shapes that vary predictably with activity pattern. Nocturnal vertebrates typically have large corneas relative to eye size as an adaptation for increased visual sensitivity. Conversely, diurnal vertebrates generally demonstrate smaller corneas relative to eye size as an adaptation for increased visual acuity. By contrast, several studies have concluded that m...

In the pineal gland, synthesis of melatonin requires O-methylation catalyzed by hydroxyindole-O-methyltransferase (HIOMT; EC 2.1.1.4). We investigated in vivo the molecular mechanisms involved in the regulation of rat pineal HIOMT messenger RNA (mRNA) expression and activity using in situ hybridization and radioenzymatic assay. HIOMT mRNA levels and activity are both detectable during the dayti...

the purpose of this research was to evaluate the effect of palatal expansion in the treatment of nocturnal enuresis. enuresis still remains a problem experienced by children and the reason is unclear.finding a final solution is being sought by the medical profession.nocturnal enuresis may lead to numerous physical and emotional problems. currently available treatment options showed satisfactory...

Animal activity during the night period is of enormous importance, since it represents approximately half animals’ lives, and monitoring this makes possible to detect problems related well-being safety, allows us infer energy expenditure on basis their level. The present study analyzes a sheep dataset created validate non-invasive techniques that can be used at abnormal nocturnal activity. allo...

BACKGROUND Treatment of nocturnal hypertension has been reported to be beneficial for primary and secondary prevention of stroke. We compared the effects of angiotensin II antagonist (losartan) and angiotensin converting enzyme inhibitor (quinapril) on nocturnal blood pressure (BP) and sympathetic nervous activity in patients with hypertension and stroke. METHODS According to a prospective, r...
