An interest in the field of algicides for swimming pools has led to a survey of the problems involved in this field. A study of the bactericidal and algicidal properties of some of the chemicals used has been reported (Fitzgerald, 1959) in which it was pointed out that some of the products available show remarkable properties in laboratory tests. The present studies demonstrate how the activity...

Most bacteria in the ocean can be motile. Chemotaxis allows bacteria to detect nutrient gradients, and hence motility is believed to serve as a method of approaching sources of food. This picture is well established in a stagnant environment. In the ocean a shear microenvironment is associated with turbulence. This shear flow prevents clustering of bacteria around local nutrient sources if they...

Material and methods. The sample was composed of 26 individuals who presented mild to moderate hypertension. The subjects were divided into two groups: the Experimental Group (EG) comprising 13 subjects (four men and nine women) and the Control Group (CG) comprising 13 subjects (seven men and six women), with average ages of 38.40 ± 8.24 and 38.36 ± 8.96 years, respectively. GE individuals took...

the purpose of this study was to determine the effect of combination specific resistance and ordinary swimming  training on breaststroke swimming  performance in young boys. twenty boys of alborz  province  swimming team age of 13±1 years ,weight 50/ 65±1/02kg and height 159/8 ±4/91cm, participated in this study. after the initial testing of the performance variable (fifty-meter record of breas...

Extracts of Hypericum, Passiflora and Valeriana are used for the treatment of mild depression and anxiety. We were interested whether a combination of Hypericum and Passiflora exerts comparable effects to Hypericum alone. We used two well-established models for investigating extracts for their anti-depressant activity, namely the effects on synaptic uptake of serotonin and the forced-swimming-t...

this study investigates the effects of melatonin on the sperm quality and testis weight after the combination of swimming exercise and nandrolone decanoate (deca). two groups of male wistar rats were treated for eight weeks as follows; group a consist of co (control), sham, n (deca), s (swimming) and ns (deca plus swimming); and group b: sham m (sham melatonin), m (melatonin), mn (melatonin plu...

Objective(s):Chronic stress has been linked to the pathophysiology of mood disorders including anxiety and depression. In this study, we aimed to investigate the effect of troxerutin (TRX), as a flavonol, on stress-induced anxiety and depression.Materials and Methods: 56 animals were randomly divided into seven groups (n=8 per group) as follows: control, saline, TRX 50, TRX 150, TRX 300, Diazep...

introduction: this study aimed to evaluate the effect of short-term creatine supplementation on oxidative stress and antioxidant enzymes after six bouts of 50-meter sprint swimming. methods: this quasi-experimental study recruited eight trained female swimmers with the mean age of 25±4.4 years and body mass index (bmi) of 21.8±4.2 kg/m2 to perform six bouts of 50-meter sprint swimming with a 12...

There is considerable intraspecific variation in metabolic rates and locomotor performance in aquatic ectothermic vertebrates; however, the mechanistic basis remains poorly understood. Using pregnant Trinidadian guppies (Poecilia reticulata), a live-bearing teleost, we examined the effects of reproductive traits, pectoral fin use and burst-assisted swimming on swimming metabolic rate, standard ...
