Evaluation of stability and biocompatibility of PHEMA-PMMA keratoprosthesis by penetrating keratoplasty in rabbits
Artificial corneas have been developed as an alternative to natural donor tissue to replace damaged or diseased corneas. This study was conducted to evaluate the stability and biocompatibility of PHEMA-PMMA [poly (2-hydroxyl methacrylate)-poly (methyl methacrylate)] keratoprostheses in rabbits following penetrating keratoplasty. Sixteen male New Zealand White rabbits aged 16 weeks were divided ...
متن کاملA high performance lithium-ion battery using LiNa0.02K0.01FePO4/C as cathode material and anatase TiO2 nanotube arrays as anode material
In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...
متن کاملPediatric keratoprosthesis.
OBJECTIVE To describe the authors' experience using keratoprosthesis to treat pediatric corneal opacity. DESIGN Nonrandomized, consecutive, retrospective interventional series. PARTICIPANTS Twenty-two eyes of 17 children with opaque corneas as a result of primary congenital disease and or previous failed keratoplasty.

متن کاملApplication of Graphene as Candidate Biomaterial for Synthetic Keratoprosthesis Skirt.
PURPOSE Synthetic keratoprostheses are required for visual rehabilitation in patients with end-stage corneal blindness. This study aimed to assess the biocompatibility of graphene material and its potential as a novel synthetic keratoprosthesis skirt material for corneal tissue engineering. METHODS Human corneal stromal fibroblasts were cultured on material surfaces including pristine graphen...
متن کاملLoose-fit polypseudorotaxanes constructed from γ-CDs and PHEMA-PPG-PEG-PPG-PHEMA
A pentablock copolymer was prepared via the atom transfer radical polymerization of 2-hydroxyethyl methacrylate (HEMA) initiated by 2-bromoisobutyryl end-capped PPO-PEO-PPO as a macroinitiator in DMF. Attaching PHEMA blocks altered the self-assembly process of the pentablock copolymer with γ-CDs in aqueous solution. Before attaching the PHEMA, the macroinitiator was preferentially bent to pass ...
