The small watershed approach is well-suited but underutilized in mercury research. We applied the small watershed approach to investigate total mercury (THg) and methylmercury (MeHg) dynamics in streamwater at the five diverse forested headwater catchments of the US Geological Survey Water, Energy, and Biogeochemical Budgets (WEBB) program. At all sites, baseflow THg was generally less than 1ng...
Objectives: (i) To expose ‘normal sleepers’ to a thirty two hour sleep deprivation protocol and evaluate the impact of this deprivation on a complex performance task i.e. The Paced Auditory Serial Addition Test (PASAT), (ii) To compare these sleep deprivation performance findings with historical data on the impact of sleepiness secondary to narcolepsy on PASAT performance measures, (iii) To inv...
Objectives: (i) To expose ‘normal sleepers’ to a 32-h sleep deprivation protocol and evaluate the impact of this deprivation on a complex performance task i.e. the paced auditory serial addition test (PASAT). (ii) To compare these sleep deprivation performance findings with historical data on the impact of sleepiness secondary to narcolepsy on PASAT performance measures. (iii) To investigate th...
Although the prevalence rates of sleep disorders at different stages of childhood and adolescence have been well established, little is known about the developmental course of general sleep problems. This also holds true for the bidirectional relationship between sleep problems and emotional as well as behavioral difficulties. This longitudinal study investigated the general pattern and the lat...
BACKGROUND Epidemiologic studies have shown an inverse or U-shaped relation between sleep duration and body mass index (BMI; in kg/m(2)). Moreover, associations between energy balance (EB) and characteristics of quality sleep (QS) have recently been reported. OBJECTIVE We assessed the relation between total energy expenditure (TEE) as well as substrate oxidation and QS after disturbed compare...
INTRODUCTION Sleep disturbance is a common nonmotor symptom of Parkinson's disease (PD) and strongly affects patients' quality of life. The relationship between excessive daytime sleepiness (EDS) and nighttime problems remains uncertain. Arguments persist regarding the risk factors for sleep disturbance among patients with PD. Furthermore, the prevalence of EDS appears to be lower in Asian coun...
