BACKGROUND Hyperlactatemia and its reduction after admission in the intensive care unit (ICU) have been related to survival. Because it is unknown whether this equally applies to different groups of critically ill patients, we compared the prognostic value of repeated lactate levels (a) in septic patients versus patients with hemorrhage or other conditions generally associated with low-oxygen t...

Nothing in the immunological constitution of human red blood cells has grown so luxuriantly such a short time as the details of the Rh antigens (Rh 'factor', a haemagglutinogen, an antigen contained in the red blood cells). Six years ago there was one antigen, Rh, and two characters, (i) Rh positive, Rh, dominant and (w) Rh negative, rh, recessive. To-day there are three antigens and eight type...

Objectives-To report the physiological responses ofindoor rock climbing. Methods-Fourteen experienced climbers (nine men, five women) performed three climbing trials on an indoor climbing wall. Subjects performed three trials of increasing difficulty: (a) an easy 900 vertical wall, (b) a moderately difficult negatively angled wall (1060), and (c) a difficult horizontal overhang (1510). At least...

Abstract Study aim : This study investigated the effect of taurine supplementation on exercise performance and recovery from resistance exercise. The was conducted with a cross-over design in double-blind manner. Material methods Ten trained males (age 21.4 ± 2.01 years; BMI: 23.6 2.5 kg/m²) ingested either (0.1g/kg) supplement or placebo (18 mg aspartame) prior to Vertical jump, flexibility, b...

abstract physical injuries during taekwondo competitions often happen due to physical contacts during fighting; therefore, a training protocol was designed in line with the physiological stress of a real competition according to la, hr and rpe changes so that the athletes could perform the techniques with a pad instead of a real opponent. for this purpose, 12 professional taekwondo players from...

Glucose is the major energetic substrate for the brain but evidence has accumulated during the last 20 years that lactate produced by astrocytes could be an additional substrate for neurons. However, little information exists about this lactate shuttle in vivo in activated and awake animals. We designed an experiment in which the cortical barrel field (S1BF) was unilaterally activated during in...

the aim of this study was to assess the effects of intermittent training on lactate level and lactate dehydrogenase enzyme activity in wistar rats. 20 male wistar rats (mean age 3 months and weight 224±14 g) were selected and randomly divided into the training (n=10) and control (n=10) groups. the training protocol consisted of running on a treadmill for 4 minutes and then 2 minutes of active r...

hemiscorpius lepturus is the most dangerous scorpion species, endemic in khuzestan province and other southwestern areas of iran, causing morbidity and mortality in children and adults. the efficacy of the antivenom for reversal of manifestation caused by venom of this scorpion is a controversial issue. in the present work, h. lepturus venom (1500 µg/kg) was subcutaneously injected into two ...
