Use of Modified 3D Scaffolds to Improve Cell Adhesion and Drive Desired Cell Responses
Use of Modified 3D Scaffolds to Improve Cell Adhesion and Drive Desired Cell Responses ~ Tissue engineering has always been a multidisciplinary research area focused on tissue regeneration and restoration of organs function, through implantation of cells or tissues growing outside the body. This approach involves the use of polymeric scaffolds, with a well-defined architecture, [...]

Characterisation of Mesenchymal Stem Cell Responses to Titanium Nanopillars for Orthopaedic Applications
Characterisation of Mesenchymal Stem Cell Responses to Titanium Nanopillars for Orthopaedic Applications ~ INTRODUCTION: Topographically structured surfaces have great potential for the direction of apposite cell responses in regenerative medicine, but most research is conducted with polymeric materials with poor load strength. In this study, the cellular response of mesenchymal stem cells (MSCs) to titanium [...]

Finite element analysis of the effects of focal adhesion mechanical properties and substrate stiffness on cell migration
Finite element analysis of the effects of focal adhesion mechanical properties and substrate stiffness on cell migration ~ Tissue cells are able to attach themselves to ligands present in the extracellular matrix (ECM), such as fibronectin, by using transmembrane integrin receptors that are connected to the cytoskeleton in the interior of the cell (Rhee, 2009). [...]

In Vivo Evaluation of an Injectable Premixed Radiopaque Calcium Phosphate Cement
In Vivo Evaluation of an Injectable Premixed Radiopaque Calcium Phosphate Cement ~ Due to an aging population together with a lifestyle that requires less movement, many elderly today have weak bone structure. One complication with a weaker bone structure is an increased fracture risk, especially in the vertebras. Vertebral compression fractures are painful. In order [...]

A type of injectable porous calcium phosphate cement in vivo
A type of injectable porous calcium phosphate cement in vivo ~ Abstract BACKGROUND: Calcium phosphate cement (CPC) has the disadvantages of brittleness, low waterborne (blood-soluble), poor mechanical property and conductibility which limit its clinical application in some degree. Therefore its modification research is in need. OBJECTIVE: To prepare a type of porous calcium phosphate cement [...]

Cohesive behavior of soft biological adhesives: Experiments and modeling
Cohesive behavior of soft biological adhesives: Experiments and modeling ~ High-performance biological adhesives composed of proteins and/or polysaccharides are found in essentially all organisms [1]. These ‘‘bio-glues’’ vary extensively in structure and capabilities according to their function and performance requirements [2,3]. In general, bio-glues are deformable and can dissipate a significant amount of energy [4,5], [...]

Covalent immobilization of antimicrobial peptides (AMPs) onto biomaterial surfaces
Covalent immobilization of antimicrobial peptides (AMPs) onto biomaterial surfaces ~ The use of biomaterial implants and medical devices such as catheters, heart valves, stents, shunts, arthoprostheses and fracture fixation devices is an increasingly common and often life-saving procedure. Although infection incidence has been reduced by asep- tic surgical techniques and prophylactic systemic antibiotic ther- apy, [...]

Flight simulation for advanced launchers
Flight simulation for advanced launchers ~ Abstract: The design of an advanced launcher, such as an aerospace plane, is strongly dependent on flight simulation. The performance of the propulsion system, highly integrated with the airframe construction, is, for instance, largely influenced by flight conditions. … Download Flight simulation for advanced launchers.PDF

HIGH RESOLUTION MAPPING WITH SMALL SATELLITES
HIGH RESOLUTION MAPPING WITH SMALL SATELLITES ~ With the launch of SPUTNIK-1 on October 4, 1957 we experienced the beginning of the space age, but it took about 15 years to launch a satellite dedicated to civil space-borne Earth surface imaging: the ERTS (Earth Resources Technology Satellite) spacecraft, later renamed to Landsat-1. The MMS (Multispectral [...]

Development of High-Performance Optical System for Small Satellites
Development of High-Performance Optical System for Small Satellites ~ 2. SYSTEM OVERVIEW The TIS system is based on an un-obscured three-mirror-anastigmat (TMA) telescope that consists of three mirrors. The optical design was simplified to use an on-axis spherical secondary mirror. The primary and tertiary mirrors are off-axis segmented aspheric mirrors. Its optical aperture is 120 [...]
