In vitro ultrastructure and biodegradation of activated plasma albumin gel derived from human samples: A prospective observational study

Clinical Advances in Periodontics, EarlyView.
Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...

CARS and SHG microscopy to follow the collagen production in living human corneal fibroblasts and mesenchymal stem cells in fibrin gel 3D cultures [PDF]

, 2011
Coherent anti-Stokes Raman scattering (CARS) microscopy is combined with second harmonic generation (SHG) technique in order to follow the early stage of stem cell differentiation within a 3D scaffold. CARS microscopy can detect lipid membranes and droplet compartments in living cells and SHG microscopy enables a strong imaging contrast for molecules ...

Crestal approach for repair of oroantral bone defects and subsequent implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.

Platelet-rich fibrin decreases adhesion to polypropylene prosthetic mesh material in ventral hernia repair

Scientific Reports
Mesh adhesion is an important complication in prosthetic hernia repairs which may lead to intestinal obstruction, enterocutaneous fistula and viscus perforation. Therefore, direct contact between visceral organs and mesh should be avoided.

Multi-scale strain-stiffening of semiflexible bundle networks [PDF]

arXiv, 2012
Bundles of polymer filaments are responsible for the rich and unique mechanical behaviors of many biomaterials, including cells and extracellular matrices. In fibrin biopolymers, whose nonlinear elastic properties are crucial for normal blood clotting, protofibrils self-assemble and bundle to form networks of semiflexible fibers.
