Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which plays crucial roles in pathogenesis of inflammatory diseases. The current study aimed to investigate the binding abilities of I44 and I49 domain antibodies to TNF-α. The dAbs were expressed in bacterial expression system and purified by affinity chromatography using Ni-sepharose column. The expression and purity of the protei...
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 histopathological findings in t...
پراکسید هیدروژن (2o2h) و عامل نکروزیس تومور آلفا (tnf-?) بیان عامل نروتروفیک مشتق از مغز (bdnf) و عامل نروتروفیک مشتق از سلول گلیال (gdnf) را افزایش می دهند که با تغییر این شاخص ها به دنبال تمرینات ورزشی نیز همراه است. ورزشکاران برای کاهش رادیکال های آزاد و عوامل التهابی ناشی از تمرین، به مصرف مکمل های ضد اکسایشی و ضد التهابی روی می آورند که می تواند با اثرات ناشی از تمرین تداخل ایجاد نماید؛ به...
