  • Publication number: 20120271362
    Abstract: A bone screw is described which includes a one-piece threaded screw body composed at least partially of a rigid foam. The screw body is headless and includes a bore extending therethrough to define a cannula and thereby providing the screw body with an annular shape defining a radial wall thickness. At least a central portion of the screw body is formed of the rigid foam which defines a matrix having a plurality of inter-connected pores therein. The inter-connected pores are disposed throughout the complete radial wall thickness of the screw body from an outer surface of the screw body to an inner surface thereof within the cannula, such as to permit bone in-growth through the complete radial wall thickness of the annular screw body. The inter-connected pores and the cannula thereby respectively allow bone in-growth through the complete radial wall thickness and the full axial length of the screw body.

  • Patent number: 8263986
    Abstract: Quantitative understanding of neural and biological activity at a sub-millimeter scale requires an integrated probe platform that combines biomarker sensors together with electrical stimulus/recording sites. Optically addressed biomarker sensors within such an integrated probe platform allows remote interrogation from the activity being measured. Monolithic or hybrid integrated silicon probe platforms would beneficially allow for accurate control of neural prosthetics, brain machine interfaces, etc as well as helping with complex brain diseases and disorders. According to the invention a silicon probe platform is provided employing ultra-thin silicon in conjunction with optical waveguides, optoelectronic interfaces, porous filter elements, and integrated CMOS circuitry. Such probes allowing simultaneously analysis of both neural electrical activities along with chemical activity derived from multiple biomolecular sensors with porous membrane filters.

  • Patent number: 8258892
    Abstract: The present invention relates to a method and system for high-speed bandpass serial data communication. A driver receives at least one data signal and generates a bandpass data signal for transmission through a bandpass waveguide interconnect. The bandpass data signal is launched into the bandpass waveguide interconnect using a first adaptor and extracted therefrom after transmission using a second adaptor. A receiver connected to the second adaptor recovers the at least one data signal from the extracted bandpass data signal. A dispersion compensation circuit receives one of the at least one data signal and the bandpass data signal and information indicative of a phase response of the bandpass waveguide interconnect and dispersion compensates the one of the at least one data signal and the bandpass data signal by compensating the phase response of the bandpass waveguide interconnect.

  • Publication number: 20120205613
    Abstract: Amongst the candidates for very high efficiency solid state light sources and full solar spectrum solar cells are devices based upon InGaN nanowires. Additionally these nanowires typically require heterostructures, quantum dots, etc which all place requirements for these structures to be grown with relatively few defects and in a controllable reproducible manner. Additionally flexibility according to the device design requires that the nanowire at the substrate may be either InN or GaN. According to the invention a method of growing relatively defect free nanowires and associated structures for group IIIA-nitrides is presented without the requirement for foreign metal catalysts and overcoming the non-uniform growth of prior art non-catalyst growth techniques. According to other embodiments of the invention self-organizing dot-within-a-dot nanowire and dot-within-a-dot-within-a-well nanowire structures are presented.

  • Publication number: 20120178690
    Abstract: Netrin proteins and their receptors regulate cell and axon migration, and are implicated in tissue morphogenesis, tumorigenesis and angiogenesis. Deregulation of mechanisms that control cell motility plays a key role in tumor progression by promoting tumor cell dissemination. Unwanted neovascularization also contributes to tumor progression and metastasis and to ocular diseases which are a leading cause of blindness. Here, we describe novel netrin-derived polypeptides and fragments or derivatives thereof that selectively inhibit cell growth, migration or branching. Methods and compositions for the treatment and prevention of conditions involving cell migration or neovascularization, such as cancer and ocular disease, are also provided.

  • Publication number: 20120179636
    Abstract: Stabilizing the visual system for any sighted mobile system increases immunity of the mobile system's gaze and reduces information processing task complexity. Two human reflexes are the optokinetic reflex and vestibulo-ocular reflex (VOR). The VOR stabilizes retinal images during head movement by producing eye movements in the opposite direction. Improved analysis of the VOR in humans would improve the diagnosis/treatment of patients, provide improvements in visual prosthesis performance for patients, and also vision systems performance for mobile robotic systems. However, an important issue for prior art mathematical analysis techniques is the requirement to classify the nystagmus segments before applying any analysis techniques, wherein this classification should be preferably performed non-subjectively. Accordingly the inventors overcome these limitations by performing classification, i.e.

  • Publication number: 20120173154
    Abstract: For measuring an oxidative stress component in a patient, an optical analyzer having a light source and a light detector is used for measuring an optical property of a medium and generating optical measurement data. A processor analyzes the optical measurement data and generates a value for one or more oxidative stress component in the form of a redox signature for the patient. Probability data of the presence of an oxidative stress dependent disease can be calculated. By observing at least one additional clinical condition of the disease, a diagnosis using said at least one additional condition and said redox signature can be obtained.
