although pyrimethamine (tindurin™) appears to be effective in the prevention and treatment of some infectious diseases, very little information exists on its unpredictable properties. we design this study to evaluate its anti-tumoral effect on a model of cell line. methods: the cytotoxic influence of pyrimethamine on prostate cell line was investigated using an in vitro colometric assay. the po...

Matrix Metalloproteinases (MMPs), these calcium-dependent zinc-containing endopeptidases play an important role in adipogenesis and angiogenesis by modifying tissues degrading the extracellular matrix (ECM). glycoproteins, gelatin, collagens, proteoglycans elastin are all found ECM. Current meta-analysis confirmed lower levels of IL-6 CRP was following bariatric surgery. Several studies have sh...

Matrix metalloproteinases are an integral component of the organ-specific tissue microenvironment, primarily participating in regulation state integrative-buffer metabolic environment, remodeling, morphogenesis and immunogenesis, genesis pathological vascular diseases. Therefore, issues related to matrix metalloproteinase activity under altered gravity a matter high urgency for space biomedicin...

Objective Matrix Metalloproteinase (MMPs) play important roles in the structural and functional properties of reproductive organs. The aim of this study is to determine the prevalence of C-1562T Matrix Metalloproteinase-9 (rs3918242) gene polymorphism in fertile and infertile men. In addition, we aimed to determine the association between C-1562T MMP-9 and G-1575A MMP-2 gene polymorphisms. Mate...

Matrix metalloproteinases (MMPs) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. MMPs have been demonstrated to increase the permeability of the blood–brain barrier (BBB) by degrading the c...

Inhibition of matrix-metalloproteinases (MMPs) by tissue inhibitors of metalloproteinases (TIMPs) has been shown in vivo to decrease metastasis and tumor-associated angiogenesis. Our laboratory is interested in understanding the role of these proteins at the pericellular microenvironment of tumor and endothelial cells. Secretion of MMPs by tumor cells enables the migration, invasion and metasta...

The recurrence rate in patients who undergo surgery for abdominal wall hernias (AWHs) is high. AWHs have been hypothesized to be a disease of the extracellular matrix, which supported by evidence showing high incidence with connective tissue disorders. This study aimed investigate most recent literature studies describing levels several matrix metalloproteinases (MMPs) blood and fascia, objecti...

Objective: Collagen is one of the main components in connective tissue (CT) and contributes to background toughness beef. It known that living animals, collagen can be degraded remodeled by collagenase matrix metalloproteinases (MMP); however, it unclear if MMP impact CT texture during postmortem aging Therefore, this study aimed understand how activity may degradation beef three different cuts...

background: one of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. matrix metalloproteinases 2 (mmp-2) and 9 (mmp-9) and their tissue inhibitors timp-1 and timp-2 are involved in the remodeling of the extracellular matrix in the ovaries. objective: this study aimed to evaluate the expression of mmp-2, mmp-9, timp-1, and timp-2 genes ...

We have previously documented that adoptively transferred IL-2-activated NK (A-NK) cells can accumulate within cancer metastases. Electron microscopic studies of pulmonary metastases have revealed that adoptively transferred A-NK cells that accumulate within metastases bind to endothelial cells and are able to traverse basement membranes. We have now extended these morphologic studies. We repor...
