Abstract: An anti-snoring mouth guard for insertion into a mouth of a user for decreasing snoring and the effects of sleep apnea includes a mouthpiece portion having a bottom wall and a pair of upstanding side walls displaced and opposite one another and extending upwardly from the bottom wall, said mouthpiece having a hemispherical configuration that is complementary to a shape of the user's teeth. Collectively, the bottom wall and pair of side walls define a channel operable to receive teeth of a user's upper pallet. The anti-snoring mouth guard includes tongue depressor portion having a proximal end coupled to the mouthpiece and having a body extending rearwardly at a generally downward angle. A brace may extend between rear ends of the mouthpiece portion and define levels by which the tongue depressor may be inserted such that the tongue depressor may be adjusted vertically and front-to-back.

Abstract: Described here are systems and methods for imaging a subject with a magnetic resonance imaging (“MRI”) system using magnetic field gradients generated by one or more gradient coils operating with gradient coil settings (e.g., gradient amplitudes, gradient slew rates) above a threshold at which peripheral nerve stimulation (“PNS”) is likely to be induced in the subject. A dielectric assembly is positioned adjacent a skin surface of the subject such that the dielectric assembly attenuates the local electric fields induced by the magnetic field gradients, which would be likely to induce PNS when the dielectric assembly is not arranged adjacent the skin surface of the subject. As a result of the dielectric assembly placed adjacent the skin surface of the subject, the gradient coil settings can be increased above the threshold without inducing PNS in the subject.

Abstract: A method of treating a sinus cavity of a subject includes advancing a distal portion of a light source through a drainage pathway of a sinus cavity and into the sinus cavity and visually observing a transdermal light emitted from the light source. A distal portion of a substantially rigid inner guide member of a balloon dilation catheter is advanced into the drainage pathway, the balloon dilation catheter including a movable shaft including a balloon that is slidably mounted on the substantially rigid inner guide member. The movable shaft and balloon are advanced distally over the substantially rigid inner guide member to place a portion of the balloon in the drainage pathway whereby the balloon is inflated.

Abstract: A system for fish identification and information that includes: a database accessible through a server via a network; a plurality of fish images stored on the database; a software application on a portable electronic device, where the portable electronic device connects to the database via the network to gain access to the plurality of fish images; and an image capture mechanism integrated into the portable electronic device where the image capturing mechanism is adapted to capture a first image for comparison with images within the plurality of fish images. Species verification is accomplished based upon the comparison of the captured fish image with images stored on the database. Further, the database also includes fish and game regulations and confirmation of fish and game regulation compliance upon species verification.

Abstract: Systems and methods for adaptive, multi-resolution magnetic resonance imaging (“MRI”], in which an MRI scan prescription is adaptively changed to acquire high-quality data from select regions-of-interest (“ROI”] in a larger field-of-view (“FOV”), are provided. The higher quality data can include data representing higher spatial resolution, higher signal-to-noise ratio (“SNR”], increased diffusion encoding via repeated acquisition with a larger number of diffusion-encoding directions, and so on. A composite image can be generated that displays the higher quality images of the ROIs overlaid on the larger FOV.

Abstract: Systems and methods for providing quantitative measurements of global glymphatic flow of cerebrospinal fluid (“CSF”) using magnetic resonance imaging (“MRI”) are described. In general, images are obtained from a subject using flow-sensitive MRI techniques that are designed to be particularly sensitive to the glymphatic flow of CSF. Measures of glymphatic flow can be obtained while the subject is in an awake state and again while the subject is in a sleep state. Based on these two measurements, a biomarker that indicates a neurological state or disease can be generated.
