An overdose of tramadol is a frequent reason for hepatic and renal toxicity possible death.Hence, this study aimed at investigating the impact on serum liver enzyme, oxidative stressm som antioxidant markers in male rabitts. Methods: A total 20 growing rabbits (7.5 weeks old) reared under high ambient temperature were divided into two equal groups, 10 each. The first group control administered ...

Plants are naturally exposed to frequent changes in environmental conditions such as salt stress affecting their growth and development, and consequently a considerable reduction in total productivity. Monodehydroascorbate reductase (MDHAR), a key enzyme in ascorbate-glutathione cycle, serves as an important antioxidative enzyme in scavenging of reactive oxygen spices (ROS). In this study, ...

Many insects in temperate regions overwinter in diapause, during which they are cold hardy. In these insects, one of the metabolic adaptations to the unfavorable environmental conditions is the synthesis of cryoprotectants/anhydroprotectants. The aim of this study was to investigate the connection between the antioxidative system and synthesis of cryoprotectants (mainly glycerol) in diapausing ...

Insects can rapidly adapt to environmental changes through physiological responses. The red flour beetle Tribolium castaneum is widely used as a model insect species. However, the stress-response system of this species remains unclear. Superoxide dismutase 2 (SOD2) is a crucial antioxidative enzyme that is found in mitochondria. T. castaneum SOD2 (TcSOD2) is composed of 215 amino acids, and has...

This work was done to clarify the relation between the changes of lipid peroxidation and the activities of antioxidative protective enzymes in lungs of rats exposed acutely, subacutely, and chronically to nitrogen dioxide. It was confirmed that the activities of the antioxidative enzymes to protect cells from oxidative stress increased in an early phase, and then the activities decreased gradua...

Cigarette smoking causes many chronic diseases but is a preventable risk factor in developing countries. However, it may be possible to relieve the smoke-induced damage by increasing the protective defense system. As vitamin C intake reduces smoking risk, it is recommended that smokers should take more vitamin C. However, the molecular mechanism of vitamin C intake on smokers has not been thoro...

BACKGROUND/AIM Chronic echinococcocal disease is the parasite human disease caused by the penetration of larval (asexual) stages of the canine tapeworm (Echinococcus granulosus) in the liver of humans. After the penetration of the parasite, the host organism react by activating complement-depending immune response. The aim of this study was to elucidate the influence of larval form of Echinococ...

Seaweed draws a lot of attention for its vital role in aquaculture as it contains beneficial biological compounds that undoubtedly might help the development this field. The current study sheds light on potential efficiency dietary supplements Grateloupia acuminata and G. doryphore (Halymeniaceae) nanoparticles (GNS) at different levels with bionanocomposite cellulose acetate membranes (CA/bio-...
