Insects are the earliest and most diverse taxon of animals accounting for more species than all other animals put together because of their high reproductive potential and varied niche. Though cellular reactions like phagocytosis, nodulation and encapsulation and humoral reaction through secretion of antibacterial proteins are known for fungus and bacterial invaders, little is known about insec...

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...

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...

exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

cellular manufacturing system (cms) is highly important in modern manufacturing methods. given the ever increasing market competition in terms of time and cost of manufacturing, we need models to decrease the cost and time of manufacturing. in this study, cms is considered in condition of dynamic demand in each period. the model is developed for facing dynamic demand that increases the cost of ...

Free radicals and other active derivatives of oxygen are inevitable by-products of biological redox reactions. Reactive oxygen species inactivate enzymes and damage important cellular components. The increased production of toxic oxygen derivatives is considered to be a universal or common feature of stress conditions. Plant and other organisms have evolved a wide range of mechanisms to contend...

Fe plays a critical role in the immune system and defence against infection. However, many aspects of the way in which Fe influences these processes at the molecular and cellular level are unclear. The present review summarizes the role of Fe in lymphocyte activation and proliferation, and discusses how Fe is handled by macrophages.

RESEARCH SPECIALINTRODUCTION During the conflicts in Iraq and Afghanistan there have been major changes in the way we care for our battlefield casualties. Clinical Guidelines for Operations and BATLS have been updated and refined to offer best practiceand this practice is based on best evidence where available. This special edition of the journal focusses on how that evidence is generated, and ...
