abstract background and aims. reliable immunohistochemical assays to evaluate the definitive role of mast cells and angiogenesis in the pathogenesis of oral reactive lesions are generally not available. the purpose of the present study was to compare mast cell count (mcc) and microvessel density (mvd) between oral reactive lesions and evaluation of the correlation between mcc and mvd in these l...

arbitrage is a known economic term, implying simultaneous transaction on commodities. for instance, a generation company (genco) may involve itself in selling fuel, emission allowance and etc., instead of generating either active or reactive power. moreover, arbitrage between active and reactive powers can, in turn, be considered. in this paper, arbitrage between active and reactive power is c...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

6- mercaptopurine (6-mp) is widely used in clinic as an immunosuppressive for treatment of acute lymphocytic leukemia, crohn's disease, and ulcerative colitis with documented unpredictable hepatotoxicity. the potential molecular cytotoxic mechanisms of 6-mp against isolated rat hepatocytes were searched in this study using “accelerated cytotoxicity mechanism screening (acms)” techniques. t...

this study presents a review on advanced oxidation processes (aop) for simultaneous removal of no and so2. aop is based on using a strong oxidant such as ozone and h2o2 which is able to generate highly reactive intermediates. the pollutant will be oxidized and removed by these intermediates. in recent years, aop has been considered as an effective and attractive technology in the field of flue ...
