BACKGROUND The six-minute walk test (6MWT) is a simple, low cost, reliable, and valid method for evaluating the functional capacity of cardiac patients. However, its early use and safety following acute myocardial infarction (AMI) is recent and has been little investigated. OBJECTIVE To evaluate and to compare the safety and the cardiac behavior of early performance of the 6MWT in patients fo...

The study purpose was to investigate the effect of complex training on aerobic and anaerobic power amateur athletes. Materials methods. included 30 athletes in soccer hockey, which were equally divided into two groups, namely an Experimental group who underwent 6 weeks along with regular their sports a Control Group only performed training. Anaerobic assessed by Running-based Sprint Test (RAST)...

Single or multiple brief periods of ischemia (preconditioning) have been shown to protect the myocardium from infarction after a subsequent more prolonged ischemic insult. To test the hypothesis that preconditioning is the result of opening ATP-sensitive potassium (KATP) channels, a selective KATP channel antagonist, glibenclamide, was administered before or immediately after preconditioning in...

BACKGROUND A novel device, the intrathoracic pressure regulator (ITPR), combines an inspiratory impedance threshold device (ITD) with a vacuum source for the generation of controlled -10 mm Hg vacuum in the trachea during cardiopulmonary resuscitation (CPR) while allowing positive pressure ventilation. Compared with standard (STD) CPR, ITPR-CPR will enhance venous return, systemic arterial pres...

The 6-minute walk test is a clinical measure of endurance, but it is not known if it is useful for individuals with mobility impairments secondary to stroke. Purposes of this study were to assess which stroke-related physical impairments influence performance in the 6-minute walk test and to evaluate if this test provides a measure of functional walking endurance after stroke. Seventy-two adult...

Diabetes is growing public health. The research investigated the modulatory roles of aqueous stem-bark extract Moringa oleifera on glucose utilization. A modified Oral Glucose Tolerance Test (OGTT) was used in studying effect absorption, four groups six rats and standard methods were to test enzyme activities (hexokinase 6 phosphatase) three rats. In OGTT, group-1(diabetic control) group-4 (nor...

introduction: intensive care unit is one of the most stressful wards for patients and it is estimated that 30 to70 percent of patients experience severe physiologic stress during admission. some of the physiologic responses to stress include increase in metabolic rate with consequent increase in body temperature, increase in cardiac output and contraction power and subsequently increase in bloo...

AIM To describe the heart rate (HR) and heart rate variability at rest, during a submaximal treadmill test and at rest posttreadmill in children with cerebral palsy (CP). METHODS Twenty children (6-11 years) with CP participated, who had Gross Motor Function Classification System levels I to III. The HR was monitored for 5 minutes seated, during a submaximal treadmill test, and after 5 minute...

The aim of this study was to analyze the in vitro behavior of the pH of different irrigating solutions, used alone or consecutively, after contact with extracted human teeth. Mandibular human premolars were selected. The middle thirds were divided into 6 parts. The specimens obtained were divided into 6 groups and treated with irrigating solutions: 1) distilled water; 2) 1% NaOCl; 3) 1% Citric ...
