Tryptophan, serotonin, and melatonin, present in Jerte Valley cherries, participate in sleep regulation and exhibit antioxidant properties. The effect of the intake of seven different Jerte Valley cherry cultivars on the sleep-wake cycle, 6-sulfatoxymelatonin levels, and urinary total antioxidant capacity in middle-aged and elderly participants was evaluated. Volunteers were subjected to actigr...

PURPOSE To compare effects of kinesio taping with sham taping at the end of 3 consecutive taping periods in knee osteoarthritis. METHODS 41 patients diagnosed with knee osteoarthritis according to American College of Rheumatology were randomized to receive either KT or sham taping. Baseline evaluations included a visual analog scale (VAS) for activity and nocturnal pain, Lequesne index for fu...

asthma  is a clinical syndrome  characterized by chronic  airway inflammation, airway responsiveness, and expiratory airflow limitation. nocturnal symptoms and decreases in lung function are common aspects of the asthma clinical syndrome. nocturnal symptoms also appear to be associated with asthma-related mortality. in addition to its importance to the regulation of human circadian rhythms, an ...

A randomised, double blind, placebo controlled crossover trial of high dose nebulised ipratropium was carried out in 10 asthmatic patients with documented nocturnal bronchoconstriction. Patients received nebulised saline or ipratropium 1 mg at 10 pm and 2 am on two nights. Absolute peak flow (PEF) rates were higher throughout the night after the patients had received ipratropium (at 2 am, for e...

Acoustic monitoring and radio-tracking were used to study the nocturnal activity of adult female Indiana bats Myotis sodalis at a maternity site in Michigan, U.S.A. Pregnant bats did not use the day roost at night, but lactating females returned 2–4 times/night for 32± 7 (SE) min/visit, presumably to feed their young. Both pregnant and lactating females night roosted as solitary individuals in ...

Patients with chronic kidney disease have less than expected decline in blood pressure during sleep (nondipping) and commonly experience the vexing symptom of nocturia. To better understand the relationship among nocturia, nighttime physical activity, and nondipping, we studied 98 patients with chronic kidney disease on 2 occasions, 1 month apart, with 24-hour ambulatory blood pressure monitori...

Circadian rhythms are fundamental to life. In mammals, these rhythms are generated by pacemaker neurons in the suprachiasmatic nucleus (SCN) of the hypothalamus. The SCN is remarkably consistent in structure and function between species, yet mammalian rest/activity patterns are extremely diverse, including diurnal, nocturnal, and crepuscular behaviors. Two mechanisms have been proposed to accou...

THE PRIMARY CLOCK MECHANISM controlling most of the circadian patterns in mammals resides in the suprachiasmatic nucleus (SCN). It appears that the feedback loops that control the 24-h period of circadian rhythms are the same in diurnal and nocturnal species (6), and yet the timing of daily peaks and nadirs of many circadian rhythms (e.g., activity, sleep, body temperature, corticosteroid relea...

1014 subjects on the island of Sardinia (Italy) were interviewed regarding the habit of clenching and grinding their teeth. They had to specify if this activity occurred during the day, during the night, or both. Other information recorded was their age, gender, marital status, and occupation. Overall prevalence of bruxism was 27.2% (276 subjects). No association was found between bruxism and a...

BACKGROUND Large ventral lateral clock neurons (lLNvs) exhibit higher daytime-light-driven spontaneous action-potential firing rates in Drosophila, coinciding with wakefulness and locomotor-activity behavior. To determine whether the lLNvs are involved in arousal and sleep/wake behavior, we examined the effects of altered electrical excitation of the LNvs. RESULTS LNv-hyperexcited flies rever...
