Bacterial contamination of urinary drainage bags is a frequent source of bladder bacteriuria in patients with indwelling catheters. Previous work demonstrated that the addition of 30 ml of 3% H2O2 prevented bacterial contamination of urinary drainage bags for up to 8 h in patients with urinary infections (greater than 10(5) colony-forming units per ml). Survival curves of a variety of organisms...

Studies on the assessment of heart rate variability threshold (HRVT) during walking are scarce. We determined the reliability and validity of HRVT assessment during the incremental shuttle walk test (ISWT) in healthy subjects. Thirty-one participants aged 57 ± 9 years (17 females) performed 3 ISWTs. During the 1st and 2nd ISWTs, instantaneous heart rate variability was calculated every 30 s and...

Objective: This study was conducted to evaluate the possible antioxidant activity and neuroprotective effects of aqueous and methanolic extracts of Althaea officinalis flowers against H2O2-induced oxidative stress in PC12 cells. Material and Methods: The antioxidant potential of extracts was evaluated by radical scavenging activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. For c...
