In this paper, a mathematical model to describe the spread of an infectious disease on farm is developed. To analyze evolution infection, direct transmission from infected individuals and indirect bacteria accumulated in enclosure are considered. A threshold value population obtained assure extinction disease. When size exceeded, two control procedures apply at each time proposed. For them, max...

MicroRNAs (miRNAs) represent a class of small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. They play a crucial role in diverse cellular pathways. Ionizing radiation (IR) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. Recently it has been discovered that mi...

recent studies have established that sex hormones directly or indirectly affect t and b cells and macrophages by manipulating the production of cytokines. in this study the possibility of the effect of 5a-dht on macrophage (mφ) nitric oxide (no) release via interleukin-l, 6 (ll-1β, il-6) or tumor necrosis factor-a (tnfα) was investigated. the endogenous cytokines il-1β, il-6 and tnf-α were neut...

Due to special conditions of Iran; i.e., neighboring to major centers of drug production in Afghanistan during the last few decades, it was the passageway of the drug to Europe. Moreover, because of appropriate context of social, economic and cultural situations, there was an increased addiction and drug trafficking in Iran. It is obvious that a lot of people would be involved directly and indi...
