conclusions: lymphatic metastasis in patients with oral and maxillofacial scc is closely related to the positive expression of vegf, mmp-9 and timp-2. mmp-9 and timp-2 can affect the progression of cancer, which is valuable for studies on oral and maxillofacial scc genes. objectives: to explore the association between expression of vegf, mmp-9 and timp-2 in oral and maxillofacial scc and clinic...

background: considering the role of matrix metalloproteinase-3 (mmp-3) and tissue inhibitor of matrix metalloproteinase-1 (timp-1) in the pathogenesis of periodontitis, the present study is to estimate the levels of mmp-3 and timp-1 in gingival crevicular fluid (gcf) in periodontal health, disease and to evaluate the effect of periodontal therapy on mmp-3 and timp-1 concentrations in gcf. mater...

The analysis of the balance elastase (MMP-2, MMP-9) and TIMP-4 was performed in order to determine their involvement pathogenesis NEC. A progressive duration NEC with sepsis is accompanied by increased serum concentrations MMP-9, MMP-2 TIMP-4. Increases MMP-2>503 ng/ml, MMP-9>812 ng/ml TIMP-4>1404 can be regarded as statistically significant predictors fatal outcome proposed method for...

Objective(s): It is known that extremely low frequency-pulsed electromagnetic fields (ELF-PEMF) influence multiple cellular and molecular processes. Retinal pigment epithelial (RPE) cells have a significant part in the emergence and pathophysiology of several ocular disorders, such as neovascularization. This study assessed the impact of ELF-PEMF on the proangiogenic features of RPE cells. Mate...

Despite significant advances in the diagnosis of tuberculosis, issues mechanism development and treatment fibrotic manifestations are relevant take place treatment. The aim study was to content perlecane find out its participation remodeling extracellular matrix organs mice with tuberculous inflammation when they were injected an antitubercular composition. Materials methods. experiment carried...

The stability of the intelligent power module has a very significant impact on operation air conditioner. In this paper, prototype experimental platform is built to verify feasibility simulation results. Next, thermal performance and flow characteristics heat sink are analyzed, including single-factor analysis interactive effects. results show that smaller pipe diameter can reduce maximum tempe...

Introduction: Chronic periodontitis is a multifactorial disease that causes rapid destruction of the tissues supporting teeth and may lead to tooth loss. Matrix metalloproteinase-13 (MMP‐13) levels have been higher in gingival crevicular fluid chronic patients tissue inhibitor metalloproteinase-1 (TIMP‐1) an endogenous MMPs implicated inflammation. This review purpose discuss relationship betwe...

Transformed human fibroblasts secrete two structurally and functionally related inhibitors of matrix metalloproteinases, tissue inhibitor of metalloproteinases (TIMP) 1 and 2. In assays measuring the relative inhibitory capability of TIMP-1 and TIMP-2 against autoactivated 72-kDa gelatinase, which consists of two major active peptides and several inactive fragments, TIMP-2 was more effective th...
