peri-implantitis is a multi-factorial disease involving peri-implant tissues and resulting in therapeutic failure. inflammatory mediators and cytokines in the gingival crevicular fluid (gcf)  have  pivotal  roles  in  the  disease pathogenesis  and  could  be  used  for  disease monitoring. therefore, the  present  study was conducted  to  compare the gcf  levels of tnf-α and il-17 between pati...

results there was no difference found between the two groups with regard to; gender, basic variables, ejection fraction (ef), cbp time and aortic cross-clamp time. the preoperative levels of il-6 and tnf-α were not different; however, their postoperative levels were significantly higher in the placebo group (p value = 0.01 for il-6 and 0.005 for tnf-α). conclusions this study showed that mgso4 ...

Background: Tumor necrosis factor alpha is a proinflammatory cytokine and  as  polyvalent initial response of inflammatory cells which facilitated through the creation of coronary atherosclerosis . It also seems that the polymorphism and susceptibility to atherosclerosis is related to TNF-α gene promoter. The purpose of this study was to investigate single nucleotide polymorphis...

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...

tuberculosis (tb) and tobacco use are two major alarming global health issues posing immense threats to human populations. mycobacterium tuberculosis (mtb) by activation of macrophages could induce the sequences of cells activation and releases of inflammatory cytokines such as cxcl-8, il-12 and tnf-α which in turn induces the immune system network. however no information is available on other ...

background: schizophrenia is a disorder of the executive function of both sensory and central nervous system. recent studies suggest that immune mechanisms play a role in the pathophysiology of this disease. the variations in cytokine concentrations have been associated with psychopathology and treatment of schizophrenia. objective: to investigate the changes in serum concentrations of tnf- α, ...

chemokines are classified in four distinct groups as cxc, cc, cx3c and c, depending on the presence or absence of a motif called elr (arg-leu-glu) before the first cysteine residue in their structure. cxc chemokines are also subdivided into elr + and elr - . increasing evidence has indicated the existence of a chemokine network in the liver which is involved in both physiological responses and,...

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...

BACKGROUND AND AIM: Recurrent aphthous stomatitis (RAS) is a lesion of the oral cavity with an unknown etiology. Several studies have been performed on the role of tumor necrosis factor-alpha (TNF-α) in RAS. The main purpose of this paper was to review TNF-α level and its gene polymorphism in patients with RAS, the factors influencing the production of TNF-α, a...

Background: Tumor necrosis factor- a (TNF-α) is a cytokine that was identified as a factor with a wide range of proinflammatory activities. The expression of bovine TNF-α in mammary tissue during pregnancy seems to have a role in development of the corresponding glands.Objective: Single nucleotide polymorphisms (SNPs) were defined in 3′-flanking region of...
