background: there is growing evidence that damage to spermatozoa by reactive oxygen species (ros) play a key role in male infertility. objective: the aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (tac) and activities of catalase and superoxide dismutase (sod) in men with asthenozoospermia, asthenoteratozoospermia and olig...
Pyocyanin, produced by Pseudomonas aeruginosa, has many deleterious effects on human cells that relate to its ability to generate reactive oxygen species (ROS), such as superoxide and hydrogen peroxide. Human cells possess several mechanisms to protect themselves from ROS, including manganese superoxide dismutase (MnSOD), copper zinc superoxide dismutase (CuZnSOD), and catalase. Given the link ...
a completely randomized design (crd) with three replications was conducted at greenhouse of urmia university in 2013 to study the effect of different methyl jasmonate concentrations (0, 0.1 and 0.5 mm) on the activity of enzymes polyphenol oxidase, phenylalanine ammonia lyase, catalase, ascorbate peroxidase, guaiacol peroxidase and total protein content in basil. activity of the enzymes and tot...
