The purpose of this study was to investigate the effects of running drills during an interval training program on biomechanical parameters of running. Thirty recreational runners, divided into 2 groups (control group and experimental group [EG]), were submitted to a 15-week interval training, but only EG performed running drills in the training. The test sessions were accomplished before and af...

seventy seven adult large mixed breed dogs of either sex were included in this study. the animals were randomly divided into four groups and received the following drug combinations intramuscularly: group 1 xylazine (0.5 mg/kg) and acepromazine (0.05 mg/kg), group 2 xylazine (0.8 mg/kg) and acepromazine (0.03 mg/kg), group 3 xylazine (0.3 mg/kg) and acepromazine (0.08 mg/kg) and group 4 xylazin...

background the increasing use of mobile phones in recent years has caused concerns about the effects of electromagnetic waves of mobile phonesonhuman biological processes. objectives this study was conducted in order to survey the effects of mobile electromagnetic waves on electro cardiogram parameters as heart rate, tp segment, pr interval, time of qrs and t waves, and voltage of r wave. patie...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...

the aim of this study was to define the electrocardiogram (ecg) changes following the moderate to severe co intoxication in rats, and also evaluating the effect of erythropoietin (epo) on observed cardiac disturbances. the growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. wistar rats were exposed...

background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...

background: the electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful. objective: removing electrocardiogram contamination from electromyogram signals. methods: in this paper, the clean electromyogram signal, electrocardiogram artifact and...

We report on the association of an X-ray source (WGA J2025.1+3342), serendipitously found with BeppoSAX in two separate observations, with the unidentified EGRET source 3EG J2027+3429. The source is detected from 1 keV up to about 100 keV, has a flat (Γ=0.6-1.5) spectrum and is highly variable both in intensity and shape. The data indicate marginal evidence for an iron line in the source rest f...
