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...

conclusion: in this study group, tnf-α -238 polymorphism was shown to be different in preeclamptic and non-preeclamptic pregnant women. the aa genotype and the a allele may carry an increased risk for developing of preeclampsia. results: there were significant differences between the two groups in tnf-α genotype at position -238 (p < 0.001). in the preeclamptic group, the frequency of the aa ge...

background: despite the emerging evidence on beneficial effects of probiotics on the cardiovascular system, their impact on the management of ischemic heart diseases and its possible mechanism have not been elucidated. methods: four viable probiotics bacterial strains, including bifidobacterium breve, lactobacillus casei, lactobacillus bulgaricus and lactobacillus acidophilus, at the concentrat...

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...

it seems that rapid destruction of gram negative bacteria by antibiotics contributes to the clinical deterioration of some patients with gram negative infections. antibiotics increase the concentration of lipopolysaccharide (lps) in blood and cerebrospinal fluids. released lps can activate blood cells to produce tumor necrosis factor-alpha (tnf-a) and other cytokines. tnf-a appears to be a majo...

Background: Pre-eclampsia is the most common critical condition during pregnancy. Plasma concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1-beta (IL-1β) increase in pregnant women with pre-eclampsia, compared to normal pregnant women. Objective: To investigate the polymorphisms of IL-1β (C+3954T), TNF-α (G- 308A), and (G-238A) in preeclemptic women northeastern Iran. Me...
