fusarium head blight (fhb) caused by fusarium graminearum is a serious disease of wheat (triticum aestivum l.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (don). a class of plasma membrane localized abc transporter proteins related to the yeast pdr5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...

cyclosporine a (csa), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. previous studies have shown that csa exposure enhances the production of reactive oxygen species (ros) and lipid peroxidation, which are directly involved in csa toxicity. to protect cells and organs against ros, the human body has evolved a...

background: breast cancer is one of the most prevalent malignancies among women in various countries. her2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. her2 gene encodes an 185kda transmembrane glycoprotein with 1255 amino acids. this active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. these...

objective(s):with regard to pharmacological effects of carvacrol on the respiratory system, its effect on cytokines genes expression in splenocytes of asthmatic mice was examined in this study. materials and methods:splenocytes were isolated from non-sensitized (control group), sensitized mice to ovalbumin (ova) (group s), and s animals treated with dexamethasone, and three concentrations of ca...

conclusions detection of drug resistance associated with mutations through real-time pcr by melting analysis technique showed a high differentiating power. this technique had high concordance with the standard proportion test and mas-pcr results. patients and methods in a cross-sectional study carried out in 2014, 90 patients with m. tuberculosis from five border provinces of iran were selected...

background herpes simplex virus infections are very common worldwide. the virus can cause infection in various body parts, especially eyes and the nervous system. therefore, an early diagnosis and highly sensitive method is very helpful. objectives the present study sought to investigate the efficiency of real-time taqman probe pcr in the diagnosis of hsv infection in suspected patients. patien...
