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...

introduction: stroke is the third important reason of death in adults and an important cause of adult disability. previous studies suggest that tgf-alpha can induce neurogenesis after stroke. here in, we studied neurogenesis effects of the tgf-alpha on subventricular zone following ischemia-reperfusion. male wistar rats (250-300 g) were divided into ischemia and treatment groups. after inductio...

Background: The process of wound healing involves integrated events including inflammation, granulation tissue formation, matrix deposition and remodeling. Growth factors play a key role in the process. Among them transforming growth factor-ß1 (TGF-ß1) is known to accelerate tissue repair by promoting the synthesis and deposition of extracellular matrix proteins. However, persistence or overact...

Systemic sclerosis (SSc) is a chronic autoimmune disease, featuring fibrosis in multiple organs. The serum from SSc patients contain inflammatory mediators, contributing to SSc pathogenesis and could be used to develop cell culture models. Here, we compared the fibrotic effects of serum samples from SSc patients with TGFβ1 on human dermal fibroblasts (HDFs). HDF cells were cultured in four diff...

Abstract Background and Aims The transforming growth factor-β1 (TGF-β1) is a pleiotropic cytokine, with distinct roles both in fibrosis inflammation acts through the Smad signalling renal injury. We sought expression of TGF-β1/Smad ANCA associated glomerulonephritis (AAGN) we assessed this correlation injury at diagnosis as well progression. Method evaluated immunohistochemical TGF-β1, phosphor...

Many nontornadic supercell storms have times when they appear to be moving toward tornadogenesis, including the development of a strong low-level vortex, but never end up producing tornado. These tornadogenesis failure (TGF) episodes can substantial challenge operational meteorologists. In this study, sample 32 pre-tornadic and 36 pre-TGF supercells is examined in 30 min pre-tornadogenesis or p...
