Abstract: This invention relates to a device and a method for monitoring and optimizing photothermal therapy, using a high-power continuous-wave laser beam and a pulsed laser beam, both transmitted through a single soft, multi-mode optical fiber with a diffuse active tip, to interstitially irradiate the target tissue at the same time. The continuous-wave laser light induces photothermal effect and increases tissue temperature and the pulsed laser light produces a photoacoustic signal. The photoacoustic signal intensity is used to monitor the temperature changes in the target tissue and to guide the irradiation of the high-power laser to optimize the photothermal effect by adjusting the light intensity and irradiation time.

Abstract: The present invention provides processes for combined applications of making grooves on an implant surface, applying MgO nanoparticles with PMMA cement, restricting the cement movement by PCL nanofiber and tethering biomolecules with PCL nanofiber to enhance mechanical stability and osseointegration of PMMA cement with bone. This is achieved through enhanced osteoconductive properties, roughness, and less viable fracture originating sites at the bone-cement interface. Such combined applications of nanoparticle and nanofiber on the mechanical stability and osseointegration of cemented implant is heretofore unknown, but as provided by the present invention can solve the debonding problem of cemented implant from bone.
Abstract: A method and apparatus for providing personalized configuration of physical supports for the human body, comprising accepting input including an individual's demographic information, neurological attributes, physical history, operational environment, and outcome or use objectives, processing user input employing an artificial intelligence engine, and then returning guidance and/or control parameters directed to seating adjustment and positioning, including incline angles for wheelchair tilt and recline.
Abstract: The present invention implements a set of grooves/ridges created on Ti at the circumferential direction to increase surface area of implant in contact with bone. These grooves/ridges protect nanofiber matrix (NFM) made with Polycaprolactone (PCL) electrospun nanofiber (ENF) and collagen at the groove from physiological loading. Controlled fabrication of a ridge made with titanium nitride (TiN) around the circumference of Ti is provided using a plasma nitride deposition technique. PCL ENF may be deposited along the sub-micrometer grooves using the electrospin setup disclosed. The method provides for fabrication of microgroove on Ti using machining or TiN deposition and filling the microgrooves with the NFM. This method has proven through experimentation to be successful in increasing in vivo mechanical stability and promoting osseointegration on Ti implants. The immobilization of MgO NP and FN with the PCL-CG NFM on microgrooved Ti as provided in the invention optimizes biological performances of Ti.
Abstract: A method for separating out nano-scale fiber threads from many fiber branches and controlling alignment and deposition of the fiber threads on a substrate, comprising: electrospinning at least synthetic polymer fiber streams from an electrically charged syringe needle; controlling the fiber using at least one electrically charged metallic disk rotating about an axis positioned below the needle; capturing the fiber using electrically grounded collector; extracting a single or plurality of fiber branch threads from the fiber streams, wherein the single or plurality of fiber branch threads is attracted to and intercepted by the collector shape, and depositing the single or plurality of fiber branch threads as substantially aligned fiber on the collector.
Abstract: A method for constructing a compound of immunologically modified nanotubes and method for using the compound to deliver immunoadjuvants to tumor cells and to produce targeted, synergistic photophysical and immunological reactions for cancer treatment. To prepare the immunologically modified nanotubes, carbon nanotubes are dissolved in a solution of glycated chitosan, an immunostimulant, hence using glycated chitosan as a surfactant for rendering the aqueous solution of nanotubes stable. The compound can be used for treatment of cancer. The method includes steps of intratumorally administering immunologically modified nanotubes and administering laser irradiation of the target tumor. The nanotube serves as a carrier to deliver immunoadjuvants to the tumor cells and serves as a light-absorbing agent in a cell body of a tumor in a host.
