three levels of lysine (90, 100 and 110% of ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. none of the dietary supplements affected the weight gain during the starter and grower periods. although no significant differences were detected between ...

The purpose of the present study was to investigate the effects of swimming training on the changes in three superoxide dismutase (SOD) isoenzymes in mice. The trained mice underwent a 6-wk swimming program (1 h/day, 5 days/wk) in water at 35-36 degrees C. Immunoreactive extracellular SOD (EC-SOD), copper- and zinc-containing SOD (CuZn-SOD), and manganese-containing SOD (Mn-SOD) contents and th...

The therapeutic potential of nonthermal plasma for cancer treatment has been reported recently. The heterogeneity of cancer cells need to be addressed to design effective anticancer treatments. Here, we show that treatment with nonthermal atmospheric-pressure plasma dissolved in a liquid (liquid plasma) induces oxidative stress in heterogeneous populations of cancer cells and ultimately kills t...

Gravity perception and gravitropic response are essential for plant development. In herbaceous species it is widely accepted that one of the primary events in gravity perception involves the displacement of amyloplasts within specialized cells. However the signaling cascade leading to stem reorientation is not fully known especially in woody species in which primary and secondary growth occur. ...

Some of the genotoxic/carcinogenic substances or metabolites in cigarette smoke are capable of passing through the placenta and harming a newborn’s health. Smoking is also known as a factor in the formation of oxidative damage and the main mechanism involved in the carcinogenic process. Predetermining this genotoxic risk can be successfully achieved by measuring certain parameters of oxidative ...

This work examined the enzymatic (superoxide dismutase-CuZn SOD, catalase-CAT, glutathione peroxidase-GSHPx, glutathione reductase-GR, and the biotransformation phase II enzyme glutathione-S-transferase-GST) and nonenzymatic (total glutathione-GSH and lipid peroxides-TBARS concentrations) biomarkers of oxidative stress and acetylcholinesterase (AChE) activity in the blood of the grass snake (Na...

background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...

conclusions consumption of ole after tumor transplantation reduced the tumor growth. on the other hand, owing to its highly-packed polyphenols, catalase and superoxide dismutase activities in tumor tissue were increased. results treatment with 150 and 225 mg/kg/day of ole reduced the tumor volume and weight (p < 0.05) compared to the first group significantly. it also increased the cat activity...
