BACKGROUND Self-reported screen time is associated with elevated health risk in children and youth; however, research examining the relationship between accelerometer-measured sedentary time and health risk has reported mixed findings. The purpose of this study was to examine the association between accelerometer-measured patterns of sedentary time and health risk in children and youth. METHO...

the aim of this investigation is to compare the effect of applying two transcutaneous electrical nerve stimulation (tens) current with different frequencies (2 hz & 100 hz) on hoffmann reflex recorded from gastrosoleus muscle of healthy people. forty female subjects between 20 to 30 years of age were participated in this quasi-experimental design. twenty of them were exposed to the 100 hz curre...

INTRODUCTION Dog walking is a purposeful physical activity that may have health benefits for humans and canines. A descriptive epidemiology of the contribution of dog walking to physically active lifestyles among dog walkers in the United States has not been previously reported. METHODS Data on youth and adults who reported walking for pet care trips (N = 1282) on the National Household Trave...

background : since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in nicu. this study aimed to investigate the effects of prone and supine positions on oxygenation (spo 2 ) in premature infants under mechanical ventilation and comparing infants’ oxyg...

We conducted this study to determine the degree of obesity influence on the hypoglycemic response of growth hormone and cortisol after weight loss of 5%. A total of 45 non-diabetic, male subjects followed in the outpatient endocrinological departments were divided into three groups comprising 15 subjects in each group, based upon body mass index (BMI) to healthy, overweight and obese group. Met...

OBJECTIVES The clinical significance of ischemia/reperfusion of the lower extremities demands further investigation to enable the development of more effective therapeutic alternatives. This study investigated the changes in the vascular reactivity of the rabbit femoral artery and nitric oxide metabolites under partial ischemia/ reperfusion conditions following cilostazol administration. METH...

tatus epilepticus is a serious and potentially life-threatening medical emergency that requires prompt intervention. The traditional definition of status epilepticus is any seizure lasting longer than thirty minutes regardless of whether consciousness is impaired, or recurrent seizures without an intervening period of consciousness between seizures. Clinically, the average seizure is less than ...

BACKGROUND AND PURPOSE The intraluminal suture middle cerebral artery occlusion (MCAO) model is increasingly used in experimental stroke studies. The purposes of this study were to determine whether (1) spontaneous hyperthermia occurs after different periods of MCAO in this model, (2) hypothalamic injury contributes to hyperthermia, and (3) hyperthermia increases infarct volume after permanent ...

OBJECTIVE The objective of the study was to evaluate effects of oxytocin-induced hyperstimulation on fetal oxygen saturation and fetal heart rate patterns. STUDY DESIGN Uterine activity of 56 women was evaluated retrospectively for hyperstimulation lasting 30 minutes using 2 definitions: group 1: 5 or more but less than 6 contractions in 10 minutes (n = 102, 30-minute periods); group 2: 6 or ...
