Ethambutol (20 mg/kg) was administered orally to 10 patients of pulmonary tuberculosis for seven consecutive days at 8 a.m. after over night fast. On 7th day serum levels were measured at 2, 4, 6, 8 and 24 hr intervals and urinary excretion was estimated at 2, 4, 6 and 24 hr following ethambutol administration. Simultaneous administration of isoniazid (300 mg, orally) for next seven days to the...

Several papers have suggested that 24-hour average blood pressure (BP) is superior to office BP in relation to hypertension target organ damage. This review article will specifically address the evidence provided in this regard by either cross-sectional or longitudinal studies. It will also critically discuss the available data supporting the concept that not only 24-hour average BP values, but...

Before the diagnostic potential of 24-hour non-invasive BP measurement can be assessed, the accuracy of ambulatory recorders must be established, and normal reference values determined. The accuracy criteria of four ambulatory BP measuring systems (the SpaceLabs 90207, the Novecor DIASYS 200, the Takeda TM-2420 and the Del Mar Avionics Pressurometer IV) have been assessed according to the Briti...

Objective: To investigate whether postural stability and adaptation differed after a normal night of sleep, after 24 h (24 SDep) and 36 h (36 SDep) of sleep deprivation while subjected to repeated balance perturbations. Also, to determine whether there was any correlation between subjective alertness scores and objective posturographic measurements. Lastly, to investigate the effects of vision ...

Blood pressure and heart rate of 15 male shift workers were measured every 15 minutes for 24 hours during three work shifts: morning, 4:00 AM to noon; afternoon, noon to 8:00 PM; and night, 8:00 PM to 4:00 AM. For each shift, 24-hour systolic and diastolic blood pressure showed a large "trough" (the low pressure span) and a continuous range of elevated pressure (the high pressure span). Fourier...

The prevalence of obesity is high in women aged 18 years which 21.8 percent. Twenty-two-year-old female students are one the populations at risk poor sleep quality and night-eating syndrome. Regular aerobic exercise can have a positive effect on followed by reduction night eating This study aims to analyze dinner syndrome obese students. was quasi-experimental design with pre-post test control ...

the purpose of this study was to conduct a quantitative risk assessment for pah exposure forconsumers at a night market in taiwan. the major methods assessed potential risk under different exposure scenarios based on bap equivalent concentration (bapeq) and incremental lifetime cancer risk (ilcr) models. we performed experimental sampling at a night market from 27 october through 22 november 20...

Lakes are generally supersaturated in carbon dioxide (CO2) and emitters of CO2 to the atmosphere. However, estimates flux () from lakes seldom based on direct measurements usually do not account for nighttime emissions, yielding risk biased assessments. Here, we present automated floating chambers collected every 2–3 hr spanning 115 24 periods three boreal during summer stratification before af...

PURPOSE Light-at-night exposure can disrupt the human circadian rhythm via clock gene expressions. The circadian rhythm influences antioxidant enzymes' activity and cellular mRNA levels of these enzymes. The employees working based on a shift system adjust to the changes occurring both on the cell level and on the level of the whole organism. Therefore, a question should be answered whether shi...

AIMS (1) To identify factors at 1 week of age which put infants at risk of failing to sleep through the night at 12 weeks of age. (2) To assess whether a behavioural programme increases the likelihood that these infants will sleep through the night at 12 weeks of age. METHODS A community sample of 316 newborn infants was employed to identify the risk factors at 1 week of age which increased t...
