A Digital Teleme'iry System for Ambulatory Sleep Rec-
نویسنده
چکیده
Commonly used cassette recorders for sleep-wake recording require frequent maintenance and have limited capacity for respiration and movement sensors. Signal amplitudes are variable due to the head-tape-head transmission. We developed a digital ambulatory telemetric system with better signal quality, less service requirements, 14 signals and specified amplitudes. The system is based on modern electronic components and a small Pc.

Central nervous system depressant activity of Russelia equisetiformis.
The central nervous system depressant activity of the crude methanol extract (REC) and fractions (RE1, RE2, and RE3) of Russelia equisetiformis were evaluated in mice using the following models: amphetamine-induced stereotypy, picrotoxin-induced convulsion and phenobarbitone sleeping time. At 200-400 mg/kg, REC significantly increased phenobarbitone-sleeping time [P < 0.05] in a dose- dependent...

متن کاملNon-Dipping Blood Pressure Profile in Narcolepsy with Cataplexy
BACKGROUND Patients with narcolepsy-cataplexy (NC) mostly exhibit undetectable hypocretin levels. Hypocretin system is one of the key players in the complex interaction between sleep and the cardiovascular system. We tested the hypothesis that hypocretin deficiency affects cardiovascular risk factors by measuring nighttime and daytime ambulatory blood pressure (BP) and the night-to-day BP ratio...
متن کاملDevices for Ambulatory Monitoring of Sleep-Associated Disorders in Children with Neurological Diseases
Good sleep quality is essential for a child's wellbeing. Early sleep problems have been linked to the later development of emotional and behavioral disorders and can negatively impact the quality of life of the child and his or her family. Sleep-associated conditions are frequent in the pediatric population, and even more so in children with neurological problems. Monitoring devices can help to...
