Abstract: A treatment for Parkinson's Disease uses a stimulus electrode implanted in a subthalamic nucleus with a chemosensor implanted in a globus pallidus pars interna (GPi) of the subject. A level of a neurochemical is sensed with the chemosensor, and compared to a desired level. When the level of the neurochemical is less than desired, an electrical stimulation is provided to the stimulus electrode. In alternative embodiments, the neurochemical sensed is glutamate or dopamine. An alternative system uses a chemosensor implanted in the striatum instead of the GPi. An alternative system for treating benign essential tremor uses a stimulus electrode implanted in the thalamus with feedback taken from a chemosensor in the striatum.

Abstract: An pulse electro thermal defrost evaporator system has multiple refrigerant tubes formed from an electrically conductive metal and connected in parallel for refrigerant flow. These tubes are, however, connected electrically in series. A controller is capable of detecting ice accumulation and connecting the tubes to a source of electrical power for deicing when it is necessary to deice the tubes. Embodiments having a manifold having multiple conductive sections insulated from each other are disclosed for coupling tubes electrically in series. Alternative embodiments with a single, long, wide-bore, tube are disclosed, as are embodiments having an evaporating pan coupled in series or parallel with the tubes, and embodiments with thermal cutoff and electrical safety interlocks.
Abstract: A heat exchanger for exchanging heat between gasses such as air and a liquid or gaseous coolant has narrow spacing between exchanger surfaces for high efficiency. To avoid undue obstruction of gas flow due to ice buildup on the exchanger surfaces, the heat exchanger is equipped with sensors to monitor the gas flow and an actuator that widens the spacing between exchanger surfaces such that gas flow remains unimpeded. Embodiments provide for defrosting of the exchanger surfaces when an limit on spacing of exchanger surfaces is reached, and for relaxing the spacing to the original narrow spacing when defrosting is completed.

Abstract: A magnetic proximity sensor is attached to a ferrous object such that the sensor alerts a practitioner if a threshold of magnetic strength has been exceeded by bringing the ferrous object within a certain proximity to the magnet of an MRI scanner. The magnetic proximity sensor includes at least one magnetic field sensor for sensing a magnetic field strength. An alarm in communication with the field sensor alerts a practitioner that a threshold of magnetic strength has been exceeded. A battery powers the field sensor and the alarm. The field sensor may produce an output voltage corresponding to the sensed magnetic field strength, and a potentiometer may provide a reference voltage corresponding to a threshold magnetic field strength. A comparator compares the reference voltage to the output voltage, and triggers an alarm if the output voltage exceeds the reference voltage.
Abstract: The present invention relates to a method for diagnosing neuroendocrine cancers via detecting the presence of N-methyl D-asparate-associated (NMDA) glutamate receptors type 1 and/or type 2. Methods for preventing and treating neuroendocrine cancers are also disclosed.
Abstract: The present invention relates to a method for producing adaptive regulatory T cells from effector T cells by contacting the effector T cells with retinoic acid. Adaptive regulatory T cells produced by this method are Foxp3+, home to the gut, and are refractory to reversion in vivo. As such, such cells find application in the treatment of autoimmune disease and facilitating transplantation tolerance.
Abstract: The present invention features compositions and methods for increasing the cell surface expression of degradation-prone CFTR proteins and preventing or treating cystic fibrosis. The invention provides peptides and peptidomimetics that selectively inhibit the interaction between CAL and mutant CFTR proteins, thereby stabilizing the CFTR and facilitating transport of the same to the cell surface.

Abstract: A knot tying system is presented containing a feeding mechanism, a knot tying device, and a clamp. The feeding mechanism has a drive roller and an idle roller capable of guiding a wire. A truck is connected to the end of the wire, and fed into a guide track, fixed relative to the feeding mechanism. The guide track provides a curved track in the shape of a knot desired. The track has a tube having a wire extraction slot running along the length of the tube, an intersection region where an outer portion of the guide track intersects an inner portion of the guide track, and a slit through the inner portion of the guide track substantially at the intersection region. A sensing and control system may also be present.
Abstract: An icemaker and a refrigerator having an icemaker are discussed. The icemaker has pulse-electrothermal ice release and includes an ice-making tray having several ice forming portions in which water is stored and ice is formed; and a housing surrounding the ice-making tray provided with at least one cold air inlet and/or ice ejection port through which cold air is supplied and ice released along a bent channel. The cold air inlet and/or ice ejection ports are baffled to prevent contact with a user's fingers and thereby reduce the possibility of electric shock.

The present invention further provides screening methods for isolating a nicotinamide riboside-related prodrug and identifying a natural source of nicotinamide riboside.
Abstract: Systems and methods determining amplitude and phase versus frequency of an incoming beam of pulsed laser light. The incoming beam is split into two beams of substantially equal intensity, one of which is delayed for a delay period t. The two split beams are recombined to shine onto a thick SHG crystal at rotation angle ? and light emitted from the thick SHG crystal is detected as data and stored with reference to the delay period t and the angle ?. The thick SHG crystal is rotated by an angle ??, and light is detected as data and stored until the thick SHG crystal has completed 360° of rotation. This is repeated for ?t increases in the delay period until a selected beam delay period range has been completed. The stored data is processed to determine amplitude and phase versus frequency of the incoming beam of pulsed laser light.
