In this work, a cellular Potts model based on the differential adhesion hypothesis is employed to analyze the relative importance of select cell-cell and cell-extracellular matrix (ECM) contacts in glioma invasion. To perform these simulations, three types of cells and two ECM components are included. The inclusion of explicit ECM with an inhomogeneous fibrous component and a homogeneously disp...

Enterprise content management (ECM) systems help organizations cope with the increasing complexity and volume of data and information. Despite the growing popularity of ECM, published literature indicates that organizations primarily use ECM for operational benefits, while the strategic decision making capabilities are rarely considered. Thus, the most significant rewards of ECM implementation ...

According to the requirements of the electronic countermeasure (ECM) integrated simulation training used in flight simulator, the tasks, missions, structure and function of ECM system are analyzed and a universal model of airborne ECM equipment which is applicable to a variety of aircraft simulators is proposed. Then the key technologies on how to design the data interfaces and configuration fi...

in this article, we estimate the vertical price transmission through the iranian rice marketing chain by usingmonthly data from march 2000 to february, 2009 and error correction model (ecm).the causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. inproducer-retail and wholesale-retail models, price transmission is asymmetric but i...

Abstract Electronic countermeasure (ECM) has become one of the most significant factors in modern warfare, course combat, electronic jamming allocation tasks need to be flexibly adjusted with change combat stage, which puts forward higher requirements for modeling and solution method this kind problems. To solve ECM dynamic weapon target assignment (ECM-DWTA) problem, a hybrid multi-target bi-l...

This study aimed to investigate the cardioprotective effects of intramyocardial injection of heart derived extracellular matrix (ECM) and cardiosphere-derived cells (CDCs) in a rat model of myocardial infarction (MI). ECM and CDCs were collected from the rat heart, and the proliferation, apoptosis and morphology of CDCs maintained on ECM were characterized in vitro. MI model was established in ...

In microvascular vessels, endothelial cells are aligned longitudinally whereas several components of the extracellular matrix (ECM) are organized circumferentially. While current three-dimensional (3D) in vitro models for microvasculature have allowed the study of ECM-regulated tubulogenesis, they have limited control over topographical cues presented by the ECM and impart a barrier for the hig...

BACKGROUND Surgical reconstruction of congenital heart defects is often limited by the nonresorbable material used to approximate normal anatomy. In contrast, biologic scaffold materials composed of resorbable non-cross-linked extracellular matrix (ECM) have been used for tissue reconstruction of multiple organs and are replaced by host tissue. Preparation of whole organ ECM by decellularizatio...

multiple sclerosis (ms) is an autoimmune disease, which is characterized by demyelination and neuroinflammation. extracellular matrix (ecm) have important role in the central nervous system (cns). alterations are happening to the ecm after the cns disorder like ms, alzheimer and other neural injury. tenasin-c (tnc) is a glycoprotein that is highly expressed in inflammatory conditions of the cns...
