Background Recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (LLLT). The aim of this study was to determine whether LLLT could induce a bio-stimulatory effects on human gingival fibroblasts (HGF3-PI 53). Therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type I gene ...
Pulmonary fibrosis, defined as the accumulation of connective tissue in the lungs, is a severe and often fatal form of interstitial lung disease. Transforming growth factor-beta (TGF-beta) is a powerful activator of connective tissue synthesis and fibroblast proliferation in the lung, and a critical paracrine signal for the development of pulmonary fibrosis. To investigate signaling pathways do...
U2OS Dr1 cells, originating from a human osteosarcoma, are resistant to the intracellular action of diphtheria toxin but contain toxin receptors on their surfaces. These cells do not have detectable amounts of fibroblast growth factor receptors. When these cells were transfected with fibroblast growth factor receptor 4, the addition of acidic fibroblast growth factor to the medium induced tyros...
RATIONALE Electrogram-based catheter ablation, targeting complex fractionated atrial electrograms (CFAEs), is empirically known to be effective in halting persistent/permanent atrial fibrillation (AF). However, the mechanisms underlying CFAEs and electrogram-based ablation remain unclear. OBJECTIVE Because atrial fibrosis is associated with persistent/permanent AF, we hypothesized that electr...
