Introduction:Oral Squamous Cell Carcinoma (OSCC) is an invasive neoplasm with a high prevalence. Matrix Metalloproteinase (MMP) has been thought to play an important role in both the invasion and metastasis of tumors. The aim of this study was to explore the significance of MMPs expression in clinical outcome of these patients. Materials:The most recognized data Bases such as PubMed, Google sc...

This paper describes an original approach to the analysis and prediction of graylevel textures gen erated as equilibrium states of Gibbs Markov random elds This approach is physically mo tivated by the analogy that exists between the graylevel textures and the miscibility patterns of multiphase ows The physics of the situation is captured using miscibility matrices that are related to the co oc...

The fluid mosaic model of Singer and Nicolson in 1972 shows how proteins are embedded in membranes. To elucidate the interactions between proteins and the surrounding lipids, stearic acid (SA) and bovine serum albumin (BSA) were used as lipid-protein components to mimic the normal membrane bilayer environment using the Langmuir-Blodgett technique. Surface pressure (π)-molecular area (A) isother...

Intraocular pressure (IOP) is maintained as a result of the balance between production of aqueous humour (AH) by the ciliary processes and hydrodynamic resistance to its outflow through the conventional outflow pathway comprising the trabecular meshwork (TM) and Schlemm's canal (SC). Elevated IOP, which can be caused by increased resistance to AH outflow, is a major risk factor for open-angle g...

Giant hysteretic effects in the YHx hydrogen switchable mirror system are observed between x51.9 and x53 in pressure composition isotherms, optical and electrical properties, and mechanical stress. Polycrystalline Y films are studied by simultaneous in situ measurements of electrical resistivity, optical transmittance and x-ray diffractometry. These experiments are linked to optical microscopy ...

BACKGROUND Mechanical ventilation can promote lung injury by triggering a pro-inflammatory response. Macrolides may exert some immunomodulatory effects and have shown significant benefits over other antibiotics in ventilated patients. We hypothesized that macrolides could decrease ventilator-induced lung injury. METHODS Adult mice were treated with vehicle, clarithromycin or levofloxacin, and...

PURPOSE To evaluate the distribution of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and their specific inhibitors in a sample of patients affected by mild dyslipidemia but not yet treated with antihyperlipidemic drugs. METHODS One hundred and sixty-eight Caucasian patients aged >or=18 yr of either sex with combined dyslipidemia and who had never previously taken li...

BACKGROUND Matrix metalloproteinase (MMP)-2 deficiency makes humans and mice susceptible to inflammation. Here, we reveal an MMP-2-mediated mechanism that modulates the inflammatory response via secretory phospholipase A2 (sPLA2), a phospholipid hydrolase that releases fatty acids, including precursors of eicosanoids. METHODS AND RESULTS Mmp2(-/-) (and, to a lesser extent, Mmp7(-/-) and Mmp9(...

Matrix metalloproteinase-9 (MMP-9) is released by neutrophils at the sites of acute inflammation. This enzyme modulates matrix turnover and inflammatory response, and its activity has been found to be increased after ventilator-induced lung injury. To clarify the role of MMP-9, mice lacking this enzyme and their wild-type counterparts were ventilated for 2 h with high- or low-peak inspiratory p...

INTRODUCTION Matrix metalloproteinase-9 (MMP-9) plays an important role in extracellular and vascular remodelling. We aimed therefore to assess the role of blood pressure (BP) control on plasma MMP-9 in relation to the presence of diabetes mellitus (DM) type II. MATERIAL AND METHODS Plasma MMP-9 was measured in 61 patients who were divided into two groups depending on their BP control as foll...
