Nanointerfacial strength between non-collagenous protein and collagen fibrils in antler bone
Antler bone displays considerable toughness through the use of a complex nanofibrous structure of mineralized collagen fibrils (MCFs) bound together by non-collagenous proteins (NCPs). While the NCP regions represent a small volume fraction relative to the MCFs, significant surface area is evolved upon failure of the nanointerfaces formed at NCP-collagen fibril boundaries. The mechanical proper...
متن کاملVitamin E improved bone strength and bone minerals in male rats given alcohol
Objective(s): Alcohol consumption induces oxidative stress on bone, which in turn increases the risk of osteoporosis. This study determined the effects of vitamin E on bone strength and bone mineral content in alcohol-induced osteoporotic rats. Materials and Methods: Three months old Sprague Dawley male rats were randomly divided into 5 groups: (I) control group; (II) alcohol (3 g/kg) + normal ...
متن کاملCollagen structure and strength in leather
Strength is an important property of leather. However the structural basis of strength in leather is not well understood. We have used synchrotron based small angle X-ray scattering to investigate the structure and strength of collagen materials under a variety of conditions. This enables changes in the extent of orientation of the collagen fibrils to be quantified and the internal stress on th...
متن کاملCollagen—Dexamethasone and Collagen-D3 Scaffolds for Bone Tissue Engineering
The aim of the study was to test the biocompatibility and osteoinductive potential of collagen with dexamethasone (Dex) and collagen with 1, 25 dihydroxycholecalciferol (D3) scaffolds on two human osteoblast cell lines, MG63 and hFOB1.19. The cell morphology was examined by SEM, the scaffolds colonization was monitored by fluorescence microscopy, viability by MTT assay and cells differentiation...
متن کاملBone strength: current concepts.
Bones serve several mechanical functions, including acoustic amplification in the middle ear, shielding vital organs from trauma, and serving as levers for muscles to contract against. Bone is a multiphase material made up of a tough collagenous matrix intermingled with rigid mineral crystals. The mineral gives bone its stiffness. Without sufficient mineralization, bones will plastically deform...
