  • Glucocorticoid-loaded nanoparticles for prevention of corneal allograft rejection and neovascularization
    Patent number: 10195212
    Abstract: Particles encapsulating a glucocorticoid such as dexamethasone sodium phosphate (DSP) into a matrix such as biodegradable poly(lactic-coglycolic acid) (PLGA) which is densely coated with hydrophilic polymer such as PEG or PLURONIC® F127, exhibit sustained release of DSP for up to 7 days in vitro. These nanoparticles can be used to prevent corneal graft rejection or corneal neovascularization.
    Type: Grant
    Filed: August 3, 2015
    Date of Patent: February 5, 2019
    Assignee: The Johns Hopkins University
    Inventors: Justin Scot Hanes, Qing Pan, Qingguo Xu, Nicholas J. Boylan, Walter J. Stark, Bing Wang, Lixia Luo

  • Transformable bed for examinations in pediatric ophthalmology
    Patent number: 9015882
    Abstract: A transformable bed for examinations in pediatric ophthalmology, especially suitable for the use of general anesthesia when conducting eye examinations, is provided. The bed may include a fixed bed board, a movable bed board, a movable seat, a movable support, a securing strap, and a main frame. The bed may be fixedly connected to the top of the main frame, the movable bed board may be rotationally connected to the top of the main frame, and the movable seat may be rotationally connected to the top of the main frame. The securing strap may be disposed on the movable bed board, in which one end of the movable support may be removably connected to the movable bed board, and another end may be removably connected to the main frame. The transformable bed may function both as an anesthesia bed and a handcart, and may be quickly switched therebetween.
