ôbjective: many studies evaluated the efficacy of exercise on some depression indices, but the effect of physical exercise in exhilarating milieu on urine 3-methoxy-4-hydroxyphenylglycol (mhpg) sulfate-the main metabolite of norepinephrine is not clear. the purpose of this research was to study the effect of a six-week intermittent walking in the water on 24-hour urine mhpg sulfate in depressed...

BACKGROUND One way of defining an individual's heart effort is to calculate the maximum heart rate to be expected given their age, but the reinnervation seen in patients who have received heart transplants makes for different calculations from patients who have suffered heart failure. The purpose of this study is to evaluate heart rate dynamics (rest, peak and percentage of predicted heart rate...

Physiological workload is used to estimate the physical demand of tasks in the workforce, but limited information is available for the various work activities in developing countries. Eighty-three randomly selected male workers participated in the present study, aimed at assessing the physiological workload of garbage collection (GC) in Rio de Janeiro, Brazil. Heart rate (HR) was obtained on fo...

BACKGROUND Calculating the maximum heart rate for age is one method to characterize the maximum effort of an individual. Although this method is commonly used, little is known about heart rate dynamics in optimized beta-blocked heart failure patients. AIM The aim of this study was to evaluate heart rate dynamics (basal, peak and % heart rate increase) in optimized beta-blocked heart failure p...

the emergency severity index (esi) is a five-level triage system that has shown promising reliability and validity. according to esi algorithm, in the presence of danger zone respiratory rate (rr), heart rate (hr) or oxygen (o2) saturation, patients should be up-triaged from esi level 3 to 2 hence, the current study aimed to investigate the value of the measurement of vital signs in predicting ...

Fairground operators are obliged to display a warning to the effect that people with heart disease should not ride on the roller coasters. A 31 year old man with a history of sustained monomorphic ventricular tachycardia induced by exercise ignored this advice and survived a ride on a roller coaster at the Glasgow Garden Festival without adverse effects. This prompted us to monitor heart rate b...

Background: New Pressor Protein (NPP) is a human plasma enzyme structurally related to b–fragment of activated factor XІІ (β-FXIIa). The objective of the present study was to investigate the effects of NPP and β-FXIIa on systolic blood pressure and heart rate in bilateral nephrectomized rats. Methods: Forty male Wistar rats (250-300 g) were sham-operated or bilaterally nephrectomized under anes...
