The titanium and its alloys are used as orthopedic dental implants due to their mechanical and bio-inert properties. The bare metal implants are not the ultimate answer for better osteogenesis and implant integration. Physical and chemical modifications are carried out to achieve the goal of improved adhesion and differentiation of the osteoblast. In this(More)
Entamoeba histolytica, the causative agent of amebiasis infects through its cyst form and this transmission may be blocked using encystation specific protein as drug target. In this study, we have characterized the enzyme chitinase which express specifically during encystation. The reptilian parasite Entamoeba invadens, used as a model for encystation study(More)
A promising strategy to influence the osseointegration process around orthopaedic titanium implants is the immobilization of bioactive molecules. This recruits appropriate interaction between the surface and the tissue by directing cells adhesion, proliferation, differentiation and active matrix remodelling. In this study, we aimed to investigate the(More)
UNLABELLED Increasing amounts of metal-based implants are used for orthopedic or dental surgeries throughout the world. Still several implant-related problems such as inflammation, loosening and bacterial infection are prevalent. These problems stem from the immediate microbial contamination and failure of initial osteoblast adhesion. Additionally,(More)
Photolithography is used in conjunction with a "silk fibroin photoresist" to form precise protein microstructures directly and rapidly on a variety of substrates. High-resolution features in two and three dimensions with line widths down to one micrometer are formed. Photo-crosslinked protein structures guide cell adhesion, providing precise spatial control(More)
To avoid the indiscriminating action of anticancer drugs, the cancer cell specific targeting of drug molecule becomes a preferred choice for the treatment. The successful screening of the drug molecules in 2D culture system requires further validation. The failure of target specific drug in animal model raises the issue of creating a platform in between the(More)
BACKGROUND The infectious and diagnostic form of Entamoeba histolytica (Eh), cause of amebic dysentery and liver abscess, is the quadranucleate cyst. The cyst wall of Entamoeba invadens (Ei), a model for Eh, is composed of chitin fibrils and three sets of chitin-binding lectins that cross-link chitin fibrils (multivalent Jacob lectins), self-aggregate(More)
Electrospun gelatin nanofibres attract attention of bioengineering arena because of its excellent biocompatibility and structural resemblance with native extracellular matrix. In this study, we have developed gelatin nanofibres using an innovative cross-linking approach to minimize cytotoxic effects. Gelatin was dissolved in water:acetic acid (8:2, v/v)(More)
Photolithographic fabrication via a "silk sericin photoresist" is used to form precise protein microstructures directly and rapidly on a variety of substrates. High-resolution and fidelity architectures in two and three dimensions with line widths down to 1 μm are formed. Photo-crosslinked protein structures provide structural iridescence and guide cell(More)
Replacement and repair of ectopic bone defects and traumatized bone tissues are done using porous scaffolds and composites. The prerequisites for such scaffolds include high mechanical strength, osseoconductivity and cytocompatibility. The present work is designed to address such requirements by fabricating a reinforced cytocompatible scaffold.(More)
