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...

R ecently, sleep-disordered breathing and nocturnal hypoxia have been recognized to increase the risk of cerebrovascular disease. Kirkham et al reported that nocturnal hypoxemia was a predictor of future cerebrovascular events in sickle-cell disease. However, it remains unclear whether nocturnal hypoxemic episodes directly lead to nocturnal onset stroke, because other predisposing conditions mi...

Timing of oviposition on a corpse is a key factor in entomologically based minimum postmortem interval (mPMI) calculations. However, there is considerable variation in nocturnal oviposition behavior of blow flies reported in the research literature. This study investigated nocturnal oviposition in central England for the first time, over 25 trials from 2011 to 2013. Liver-baited traps were plac...

BACKGROUND New insights have expanded the influence of the vestibular system to the regulation of circadian rhythmicity. Indeed, hypergravity or bilateral vestibular loss (BVL) in rodents causes a disruption in their daily rhythmicity for several days. The vestibular system thus influences hypothalamic regulation of circadian rhythms on Earth, which raises the question of whether daily rhythms ...

Since nocturnal symptoms indicate more severe asthma, we investigated their frequency in a hospital-based population of asthmatic children. Recognition of these symptoms offers the possibility to introduce appropriate treatment. We studied 796 consecutive children with asthma (mean (SD) age 9 (4) yrs) attending a hospital clinic, to determine whether these nocturnal symptoms predicted that dayt...

BACKGROUND A correlation has been observed between obstructive sleep events and sleep quality. The aim of the study was to assess if there is also a correlation between nocturnal hypoxemia and hypercapnia and sleep efficiency and sleep fragmentation in children. METHODS Nocturnal pulse oximetry (S(pO(2))) and transcutaneous carbon dioxide (P(tcCO(2))) recordings with simultaneous actigraphy ...

PURPOSE OF REVIEW This article summarizes the clinical and electrophysiologic manifestations of nocturnal seizures, particularly nocturnal frontal lobe epilepsy (NFLE), parasomnias, and other disorders presenting with complex behaviors in sleep. The evaluation and treatment of patients with complex nocturnal behaviors can be challenging. While the differential diagnosis of sleep-related movemen...

Nocturnal and daytime whole-canopy transpiration rate (E) and conductance (g = E/VPD, where VPD is leaf to air vapor pressure difference) were assessed gravimetrically in drought-treated and well-watered 3-year-old saplings of live oak species (Quercus series Virentes Nixon) from the southeastern USA (Quercus virginiana Mill.) and Central America (Q. oleoides Cham. and Schlecter). Our objective...

To assess left ventricular (LV) function in patients with atrial septal defect (ASD), we used radionuclide cineangiography at rest and during exercise in 11 patients (ages 16-59 years, mean 36 years) without other cardiac abnormalities. All patients had normal LV ejection fraction (EF) at rest (mean 59 ± 3% vs normal 57 ± 1%; NS); during exercise, four patients increased LVEF normally, four had...
