background:  levels of anti-inflammatory cytokines in blood have a positive relationship with congenital heart disease (chd). we sought to assess the difference in serum cytokines levels between children with and without chd.  methods:  we recruited 60 patients with chd and 30 healthy children, from 2013 to 2014. patients with primary pulmonary hypertension; metabolic diseases; renal, endocrine...

background: probiotics are microorganisms that may influence brain function via altering brain neurochemistry. new research evidence suggests that probiotic bacteria might protect tissue damage through diminishing the production of free radicals and/or inflammatory cytokines. therefore, this study was designed to evaluate the effects of probiotic bacteria on the prevention or reduction of brain...

background: the role of mesenchymal stem cell in cellular therapy is the subject of interest for many researchers. the differentiation potential of mscs and abilities in modulations of the recipient’s immune system makes them important cells in tissue regenerative studies. mscs by releasing the proinflammatory cytokines play important role in immunomodulatory systems; however the signaling path...

background: preeclampsia is a disorder unique to pregnancy and has long been recognized as an important contributor of maternal and fetal morbidity and mortality. it is suggested that cytokines such as tumor necrosis factor-alpha (tnf-α) have an important role in the pathogenesis of preeclampsia and may cause generalized endothelial dysfunction. objective: the aim of this study was comparison o...

background: inflammatory response following surgical trauma has long been a matter of study. results, however, have been varied. we sought to assess changes in the levels of proinflammatory and anti-inflammatory cytokines in patients undergoing laparoscopic and open cholecystectomy and their impact on the clinical outcome of patients concerning the postoperative pain score. methods: the study i...

background the association between tumor necrosis factor-alpha (tnf-α) (-308 g/a) gene polymorphisms and level of tissue destruction and periodontal disease progression is not proved. objectives the present study investigated the stereological parameters of interdental papilla in chronic periodontitis (cp) patients with tnf-α (-308 g/a) gene polymorphisms. materials and methods sixty gingiva sa...

background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...

conclusions the results indicated that there was a positive association between susceptibility to chronic hbv infection and tnf-α polymorphism. in addition, hbv patients carrying -308 gg, -857 cc, and -863 aa genotypes with lower serum levels of tnf-α had an increased risk of infection. background the host genetic background regulates the natural history of chronic hepatitis b virus (hbv) infec...

background host genetic and environmental factors are involved in development of gastric cancer. tumor necrosis factor (tnf)-î±| has a key role in helicobacter pylori -induced gastritis. we analyzed the association between tnf-î± polymorphism and the risk of gastric cancer in an iranian population residing in northeastern iran. materials and methods in a case-control study, the genotyping was c...
