background: bone resorption is one of the main features of inflammatory periapical lesions and is mainly mediated by interleukin-1 beta (il-1β), tumor necrosis factoralpha (tnf-α) and prostaglandin-e2 (pge2). recent investigations of these lesions revealed that pharmacological modulation may be possible. objective: the aim of this study was to evaluate the effect of ibuprofen on il-1β, tnf-α an...

many species of tea (camellia sinensis) and cowslip (echium amoenum) are used in iranian traditional medicine. the aim of this study was to conduct the survey on the ability of iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (tnf-alpha) by non-infected and infected mouse macrophages. a macrophage infection model with legionella pneumophila and enzyme linked im...

conclusions special high-risk groups, including patients with ltbi, should be treated before receiving tnf-α inhibitors. the tuberculin skin test (tst) is a somewhat cost-effective test for the diagnosis of ltbi. however, its usefulness with respect to false results should be re-evaluated in this situation. results there were somewhat different approaches proposed by various researchers regardi...

spinal cord injury (sci) as a destructive crash result in neurons degeneration. the sci lead to the onset of biochemical and molecular cascades such as inflammation that in turn has a key role in neurodegeneration development. the previous studies demonstrated the role of tnf-α and inos genes in intensifying the process after sci. as a consequence, these genes overexpression intensify the infla...

objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

conclusions in the chinese han population that we studied, nafld patients who carry the tnf-α-238 ga polymorphism have an increased risk of developing cad. mechanisms underlying this potentially important association require further investigation. background cardiovascular events account for the main cause of death in patients with non-alcoholic fatty liver disease (nafld), and are largely infl...

crohn’s disease is an inflammatory bowel disease (ibd), characterized by chronic intestinal inflammation that causes the loss of immune tolerance leading to bizarre inflammatory signals and disruption of mucosal barriers. environmental triggers and interaction of genetic determinants also play an indispensible role. in this case report, we present a pre-pubertal girl with intermittent and refra...

pre-eclampsia is a pregnancy-specific syndrome that may be dangerous especially to the fetus. different cytokines have been found to be elevated in women with pre-eclampsia and may have possible roles in the development of this disorder. alleles of the interleukin-l-beta (il-lβ) and tumor necrosis factor alpha (tnf-α) genes are associated with pr-eeclampsia in several studies in different popul...

conclusions according to our result, 1525g/a and 1595c/t were in strong linkage disequilibrium and the polymorphisms of the trail gene in the 3’ utr region were not associated with the outcome of hbv infection. results our data showed that genotypes 1525g/a and 1595c/t were in complete linkage disequilibrium and the genotype frequencies at the two positions were the same. no significant differe...
