Background: This study was designed to evaluate whether or not T. gondii and its derivatives can change the gene expression level of IL-10 in murine leukocytes in vivo.   Methods: Fifty BALB/c mice were divided into 5 groups, four of which received the excretory/secretory product (ESP) from cell culture medium, the ESP from cell free medium, the Toxoplasma lysate product (TLP) and the a...

Introduction: Increasing levels of free radicals in the ova reduce the quality of their fertilization. Investigations have revealed the elevated production of tissue and serum-free radicals in women with polycystic ovary syndrome. Sirtuin-3 is located in mitochondria and plays an important role in the deactivation of free radicals. This study aimed to investigate the expression of the Sirtuin-3...

Background: Inflammatory enzymes and free radicals are important factors affecting the immune system. However, there seems to be no detailed information about the extent to which these factors can affect superoxide dismutase 1 gene expression in female athletes, especially in incremental exercises. Therefore, the aim of the present study was to investigate the correlation between superoxide dis...

Background: Researchers are always trying to find specific markers which express specifically in cancer. These specific markers help to diagnose and treat cancer without affecting normal tissues. Cancer-testis antigens are among the new promising biomarkers, especially for targeted therapy. These markers are specially expressed in testis. Various studies have been reported individual expression...

according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
