background and aims. the role of cytokines in the immunopathogenesis of oral lichen planus (olp) has received much attention. the aim of this study was to evaluate the serum levels of tnf-α and tgf-β in patients with olp in an iranian population. materials and methods. thirty-two patients with olp and 32 age-matched healthy volunteers as a control group were included in this study. serum tests ...

مقدمه افزایش سن، سندروم متابولیک و عوامل التهابی از عوامل موثر در کاهش حجم مغز و افت عملکرد شناختی می باشد. هدف از این تحقیق بررسی اثرگذاری 12 هفته تمرین هوازی با شدت متوسط بر bdnf و tnf-α زنان 50-65 ساله مبتلا به سندروم متابولیک می باشد. روش کار این مطالعه به روش نیم تجربی و از نوع کاربردی با طرح پیش آزمون – پس آزمون و گروه کنترل در شهر زنجان درسال 1394 انجام شده است. 24 زن مبتلا به سندروم متا...

background: in this study, the pilot production of aerobic bioreactor tropical theileriosis vaccine was optimized with the aim of immunological assays for further mass production. methods: we have shown earlier the delayed type hypersensitivity (dth) assay could be used for evaluating the immunity and memory cells against specific theileria antigen in vaccinated animals. in addition, tnf-α is t...

Objective(s): This study aimed to explore the contribution of tumor necrosis factor (TNF) in the recruitment of B-cell and secretion of immunoglobulins (Igs) during cerebral tuberculosis (TB).Materials and Methods: In this work, the contributing role of TNF in regulating Ig secretions was investigated by comparing wild type TNF (TNFf/f),...

Background: TNF-α is a multifunctional proinflammatory cytokine and TGF-β1 is a secretory protein controlling epithelial proliferation and differentiation. Keratocyst presents an aggressive behavior and a growth mechanism different from that of radicular cyst. Aim: In this line, the present study aimed at evaluating TNF-α and TGF-β1 level and its association with histopath...

Background: Studies have been carried out to evaluate the association of tumor necrosis factor-α (TNF-α) gene promoter region polymorphisms with recurrent pregnancy loss (RPL) risk. However, the results remain controversial and incomplete. Hence, we performed a meta-analysis to evaluate the association of TNF-α -308G>A and -238G>A polymorphisms with RPL risk. Materials and Methods: A comprehens...
