BACKGROUND The literature describes contradictory data regarding the onset of the baroreflex reduction in spontaneously hypertensive rats. OBJECTIVE This investigation was undertaken to evaluate the baroreflex function in 13-week-old spontaneously hypertensive rats. METHODS Male Wistar Kyoto (n=15) and spontaneously hypertensive rats (n=15) aged 13(More)
PURPOSE To compare baroreflex sensitivity among conscious rats of the same strain. METHODS Male WKY rats (eight weeks old) were studied. Cannulas were inserted into the abdominal aortic artery through the right femoral artery to measure mean arterial pressure (MAP) and heart rate (HR). Baroreflex gain was calculated as the ratio between variation of HR in(More)
OBJECTIVES There are no data in the literature with regard to the acute effects of different styles of music on the geometric indices of heart rate variability. In this study, we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of heart rate variability in women. METHODS We conducted this study in(More)
UNLABELLED BACKGROUND With prolonged physical activity, it is important to maintain adequate fluid balance. The impact of consuming isotonic drinks during and after exercise on the autonomic regulation of cardiac function is unclear. This study aimed to analyze the effects of consuming an isotonic drink on heart rate variability (HRV) during and after(More)
Previous studies have already demonstrated that auditory stimulation with music influences the cardiovascular system. In this study, we described the relationship between musical auditory stimulation and heart rate variability. Searches were performed with the Medline, SciELO, Lilacs and Cochrane databases using the following keywords: "auditory(More)
We evaluated short-term effects of sidestream cigarette smoke (SSCS) exposure on baroreflex function in spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) normotensive rats. Rats were exposed to SSCS during three weeks, 180 min, five days per week, in a concentration of carbon monoxide (CO) between 100 and 300 ppm. We observed that SSCS exposure(More)
BACKGROUND The literature has already demonstrated that cigarette influences the cardiovascular system. In this study, we performed a literature review in order to investigate the relationship between sidestream cigarette smoke (SSCS) and cardiac autonomic regulation. METHODS Searches were performed on Medline, SciELO, Lilacs and Cochrane databases using(More)
OBJECTIVES We investigated the effects of chronic (eight weeks) low-to moderate-intensity swimming training on thermal pain sensitivity in streptozotocin-induced diabetic female rats. METHODS Female Wistar rats (n = 51) were divided into the following groups: trained streptozotocin-induced diabetic rats [hyperglycemic trained (HT)], sedentary(More)
INTRODUCTION Open tibial fractures are usually caused by high-energy trauma. There is no consensus about the best treatment for these fractures. Biomechanical studies show that fixing on two planes approaches the rigidity of the bone, whereas the use of interlocking intramedullary nailing is widely used and reported to produce better therapeutic results in(More)
BACKGROUND Chronic classical music was reported to increase parasympathetic activitywhen evaluating heart rate variability (HRV). It is poor in the literature investigation of the acute effects of baroque and heavy metal styles of musical auditory stimulation on HRV. In this study we evaluated the acute effects of relaxant baroque and excitatory heavy metal(More)
