Background: Regular exercise can alleviate oxidative stress. There are no studies examining changes in this variable as a result of an intense acute taekwondo (TKD) exercise. Objectives: We aimed to investigate the effect one bout TKD on superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), total antioxidant capacity (TAC), and malondialdehyde (MDA) adolescent female taekwon...

The quality characteristics of velvet antlers obtained from Formosan sambar deer (Cervus unicolor Swinhoi) (SDVA), harvested from 63 to 81 d during the velvet antler growth period, were evaluated by investigating the relationships between antioxidant levels; including content, activity, and content/activity ratios, and physical properties; including shear force values, color, and Ca content. Th...

Clinical and experimental evidence suggests a protective role for the antioxidant enzyme glutathione peroxidase-1 (GPx-1) in the atherogenic process. GPx-1 deficiency accelerates atherosclerosis and increases lesion cellularity in ApoE(-/-) mice. However, the distribution of GPx-1 within the atherosclerotic lesion as well as the mechanisms leading to increased macrophage numbers in lesions is s...

One purpose in this research was to determine the toxic effects of Cd on antioxidant enzymes of Oxya chinensis (Orthoptera: Acridoidae). Changes in the activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and guaiacol peroxidase (GPx) were measured in O. chinensis insects injected with Cd(2+). Fifth-nymphs of O. chinensis insects were injected with Cd(2+) at differe...

Chilling whole rice seedlings at 5 degrees C significantly increased the time needed to recover linear growth and reduced the subsequent linear rate of radicle growth. Subjecting nonchilled seedlings to a 45 degrees C heat shock for up to 20 min did not alter subsequent growth, whereas a 3 min heat shock was optimal in reducing growth inhibition caused by 2 days of chilling. The activity of fiv...

Antioxidant enzymes seem to play roles in controlling the luteal function and the luteolytic action of prostaglandin F2α (PGF). The aim of this study was to clarify the roles of catalase (CAT) and glutathione peroxidase (GPx) in the luteolytic action of PGF in both corpus luteum (CL) and cultured luteal cells. Corpora lutea were collected at the early (days 2-3), developing (days 5-6), mid (day...

Objectives: This study aimed to investigate the effects of six-week continuous training (CT) and high-intensity interval (HIIT) protocols on brain superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) activities their associations with short-, mid-, long-term memory in albino Wistar rats. Methods: In this study, 18 male rats (5 months old) were randomly assigned three equal (...

The aim of this study was to investigate the response different doses lipopolysaccharide (LPS) and extracellular product (ECP) antigens (25, 50, 100, 250, 500 µg) obtained from Flavobacterium psychrophilum changes in oxidative stress parameters (catalase [CAT], superoxide dismutase [SOD], glutathione peroxidase [GPx], glucose 6-phosphate dehydrogenase [G6PD], reductase [GR], malondialdehyde [MD...

Autism is a behaviorally defined disorder of unknown etiology that is thought to be influenced by genetic and environmental factors. High levels of homocysteine and oxidative stress are generally associated with neuropsychiatric disorders. The purpose of this study was to compare the level of homocysteine and other biomarkers in children with autism to corresponding values in age-matched health...
