Relevance. Сardiovascular status could be assessed by maximal aerobic capacity (VO2max) through direct analysis of the gases involved in pulmonary ventilation and monitoring fluctuations intervals between beats over time as heart rate variability. The aim study was to investigate relationship VO2max variability young adults. Materials Methods. A total 100 adults ages 18 25 were included observa...

Objective: Rosa damascena mill L. (R. damascena) is a well-known plant with fragrant effects. Several therapeutic effects of this plant on respiratory, gastrointestinal and nervous systems have been reported. It is also suggested to have beneficial effect on cardiovascular system especially blood pressure regulation. The present study was carried out to evaluate acute cardiovascular effect of h...

BACKGROUND Numerous studies were carried out to develop more sophisticated dressings to expedite healing processes and diminish the bacterial burden in burn wounds. This study assessed the healing effect of nettle extract on second degree burns wound in rats in comparison with silver sulfadiazine and vaseline. METHODS Forty rats were randomly assigned to four equal groups. A deep second-degr...

We used intraneural recordings of sympathetic nerve activity in conscious humans to determine if central command increases sympathetic discharge to resting skeletal muscle during static exercise. In nine healthy subjects, we measured arterial pressure, heart rate, and muscle sympathetic nerve activity with microelectrodes in the peroneal nerve of the resting leg during 1) static handgrip at 15%...

BACKGROUND Our aim was to evaluate electrocardiographic and echocardiographic properties and exercise response of patients with fibromyalgia (FM). METHODS The study included 60 women with primary FM and 30 healthy individuals. Resting electrocardiography, echocardiography and exercise treadmill test were used to compare these two groups. At apical four-chamber window, samples of transmitral d...

PURPOSE To ask whether dose-rate influences low-dose hyper- radiosensitivity and induced radioresistance (HRS/IRR) response in rat colon progressive (PRO) and regressive (REG) cells. METHODS Clonogenic survival was applied to tumorigenic PRO and non-tumorigenic REG cells irradiated with (60)Co γ-rays at 0.0025-500 mGy.min(-1). Both clonogenic survival and non-homologous end-joining (NHEJ) pat...

Recent studies have suggested that an exaggerated blood pressure response to maximal exercise may be useful in detecting individuals who are prone to developing hypertension in later years. To examine the hypothesis that regular aerobic exercise results in a smaller blood pressure response to maximal exercise, 26 endurance-trained and 31 untrained individuals (matched on age and physical charac...

in aim of this research was to investigate the effect of a decrease in the number of practice sessions and an increase in exercise intensity on aerobic and anaerobic power, body fat percentage, and body mass index. 80 subjects (average age: 20.2±1.53 years and height: 160.18±5.43cm) were divided into 4 groups (3 experimental groups and one control group). the experimental groups exercised with ...
