Abstract: The invention relates to selective small molecule human constitutive androstane receptor (hCAR) activators of Formula (I) or (II), pharmaceutical compositions thereof, and use thereof for the treatment of hematologic malignancies and other cancers. The small molecule hCAR activator in combination with CPA based chemotherapy regimen provides a synergistic effect to help promote cytoxicity of the cyclophosphamide (CPA) based anticancer treatments including CHOP regimen (CPA, doxorubicin, vincristine, and prednisone) by preferential induction of CYP2B6 over CYP3A4 and promoting the formation of therapeutically active CPA metabolite 4-OH-CPA.

Abstract: A method for beam therapy is provided. The method includes receiving first data indicating a plurality of target volumes within a target region inside a subject for particle beam therapy relative to a particle beam outlet on a gantry for directing a particle beam from a particle beam source. The method further includes moving automatically, one or more energy modulator components to reduce an energy of the particle beam and deliver the particle beam to the target region such that a Bragg Peak is delivered to at least one target volume of the plurality of target volumes. The method further includes repeating the moving automatically as the particle beam source rotates with the gantry around the subject, without changing the energy of the particle beam at the particle beam outlet, until every target volume is subjected to a Bragg Peak.

Abstract: A nonlinear closed-loop control combined with an integral time-delay feedback control is disclosed to adjust a speed ratio of an infinitely variable transmission (IVT) system. A speed ratio control for an IVT system involves a forward speed controller and a crank length controller for different speed ranges. The time-delay control is designed to reduce speed fluctuations of the output speed of an IVT with an accurate speed ratio. The speed ratio of an IVT with the disclosed control strategy can achieve an excellent tracking response for the desired constant output speed and reduce speed fluctuations of the output speed of an IVT by the time-delay feedback control.

Abstract: Apparatus and methods for performing a non-invasive procedure to repair a cardiac valve are described herein. In some embodiments, apparatus and methods are described herein for repairing a mitral valve using an edge-to-edge repair to secure the mitral valve leaflets. Implant securing devices are also described that can be used during a procedure to repair a mitral valve. In some embodiments, an implant securing device includes an outer member and an inner member movably disposed within the outer member. The inner member can be used to hold or secure a suture extending from an implant deployed on an atrial side of a leaflet of a mitral valve, and the outer member can be used to push or move a half hitch knot toward a ventricular side of the leaflet, which can be used to secure the implant in the desired position.

Abstract: Disclosed is a system and method for the placement of elongate medical members within a patient’s body using coaptive ultrasound that combines magnetic guidance with ultrasound visualization of the medical member in the patient’s body. A coaptive ultrasound probe adaptor magnetically attracts an elongate medical member within the patient with sufficient force so as to allow the operator to manually guide the member to its intended location. The adaptor mates with an ultrasound probe to provide the medical operator ultrasound feedback of the position of the member, thus allowing internal placement without the need for more specialized medical equipment.
Abstract: Dural repair devices that are configured to effectively and reliably repair the damage of a dural tear due to incidental durotomies are provided, along with methods of use. The devices and methods enhance the ability of a surgeon to repair a patients dura mater, or dura, during surgery of the central nervous system. The dural repair device has a multi-layer structure configured to exert a pressure or tamponade effect to compress a patient's dura to its state prior to the spinal surgery. Thus, the dural repair devices and methods of use may reduce the patients risk morbidity, further surgery, spinal headaches, or other injuries and discomforts.
Abstract: Provided herein are methods to predict pain sensitivity and pain intensity to prolonged pain in a subject. Electroencephalograms are recorded in a pain-free state or, alternatively, in a pain-free state and after applying a prolonged pain stimulus in a prolonged pain state. Pain-free and prolonged pain peak alpha frequencies or ?PAF are measured. These values correlate negatively with the likelihood of increased pain sensitivity and increased pain intensity. Also provided is a method for predicting a likelihood of chronic pain in a subject after a medical procedure and designing a plan to treat the chronic pain.

Abstract: The present invention provides for recombinant Endo-S mutants that exhibit reduced hydrolysis activity and increased transglycosylation activity for the synthesis of glycoproteins wherein a desired sialylated oxazoline or synthetic oligosaccharide oxazoline is added to a core fucosylated or nonfucosylated GlcNAc-protein acceptor. Such recombinant Endo-S mutants are useful for efficient glycosylation remodeling of IgG1-Fc domain to provide different antibody glycoforms carrying structurally well-defined Fc N-glycans.
Abstract: An oxygen supply unit for use with a blood oxygenator comprises an oxygen concentrator and a carbon dioxide scrubber. In an on-line operational mode, oxygen-rich gas from the oxygen concentrator is predominantly supplied to the blood oxygenator with a reduced flow of recycled gas from the concentrator. In an off-line operational mode where the oxygen supply unit is being powered by battery only, a larger flow of recycled gas from the blood oxygenator is passed through the carbon dioxide scrubber and combined with a lesser amount of oxygen-rich gas from the oxygen concentrator. The oxygen supply unit may be used in combination with a blood pump and oxygenator to provide ambulatory blood oxygenation to patients with compromised lung function.
