The antioxidant potential of foods plays a vital role in counteracting oxidative stress and its consequences the body. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) are primary line defence against cellular damage caused by reactive oxygen species (ROS). Glutathione is considered to be most for body because changes during increase risk CVD. dietary capacity supporting...

Brown garden snails (Helix pomatia L.), spend cold winter seasons as well as dry and hot summer seasons in torpor, which is characterized by a strong reduction of metabolic rate (Guppy &Withers, 1999). At the end of winter torpor the snails enhance the capacity of their antioxidant defence system to prevent oxidative stress, which accompanies return from hypometabolism to activity (Nowakowska e...

The interrelationship among water-stress-induced abscisic acid (ABA) accumulation, the generation of reactive oxygen species (ROS), and the activities of several antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) was investigated in leaves of detached maize (Zea mays L.) plants exposed to -0.7 MPa water stress induc...

Reactive O(2) species (ROS) are produced in both unstressed and stressed cells. Plants have well-developed defence systems against ROS, involving both limiting the formation of ROS as well as instituting its removal. Under unstressed conditions, the formation and removal of O(2) are in balance. However, the defence system, when presented with increased ROS formation under stress conditions, can...

Oxidative stress, which is associated with an increased concentration of reactive oxygen species (ROS), is involved in the pathogenesis of numerous diseases including cancer. In response to increased ROS levels, cellular antioxidant molecules such as thioredoxin, peroxiredoxins, glutaredoxins, DJ-1, and superoxide dismutases are upregulated to counteract the detrimental effect of ROS. However, ...

The present study was undertaken to assess the beneficial effects of a daily consumption of 8 % freeze-dried red-pigmented leafy lettuce (Lactuca sativa) on CVD. C57BL/6J mice were fed a high-fat high-cholesterol diet supplemented with or without red-pigmented leafy lettuce for 4 weeks. The present results showed that the red-pigmented leafy lettuce-supplemented diet significantly decreased the...

Antioxidants function as blockers of radical processes and eliminate harmful reactive oxygen species (ROS) produced during normal cellular metabolism. A complex antioxidant defence system has evolved to protect the cellular homeostasis. This system includes antioxidant enzymes (AOEs), such as superoxide dismutases (SODs), which are intracellular MnSOD and CuZnSOD and extracellular ECSOD, H2O2 s...

the effective and sustainable environmental performance of a business is a result of various factors and most important the integrated outcome of the environmental management. likewise, the integration of environmental protection into the armed forces functions has also gain interest for the military sector internationally. therefore, the environmental management system (ems) is recognized as o...

This comment discusses the study by Videla and colleagues in this issue of Clinical Science in which they have analysed surgical liver biopsies from obese patients with non-alcoholic fatty liver disease and demonstrate that fatty liver is associated with a state of oxidative stress and a decreased antioxidant activity. As the disease progresses to steatohepatitis, the defect in antioxidant syst...
