Abstract: In one aspect, the present invention relates to a system evaluating a surgical margin of tumor tissues of a living subject. In one embodiment, the system includes a light source configured to emit a source light; at least one optical probe; a scanner; a spectrometer; and a controller coupled with the scanner and the spectrometer for operably controlling the scanner and the spectrometer. In operation, a working end of the optical probe is positioned proximate to a surface of a specimen of the tumor tissues. A source channel of the optical probe deliver the source light emitted by the light source from the working end to the surface of the specimen, and a plurality of collection channels collect from the working end diffused/reflected light generated from interaction of the source light with the specimen. The spectrometer receives the collected diffused/reflected light to evaluate a margin status of the specimen.

Abstract: The present invention relates to compositions and methods for treating diseases associated with dyslipidemia, including hypercholesterolemia, hypertriglyceridemia, steatohepatitis, atherosclerosis, obesity, hyperglycemia, metabolic syndrome, and related aspects of and conditions associated with metabolic syndrome. The compositions and methods disclosed herein are useful for regulating the lipid balance (lipid homeostasis) in a subject. Compositions and methods including a Nuclear Transport Modifier may be administered to a subject to modulate the transport of transcription factors, mediated by nuclear import adaptors, into the nucleus of a cell resulting in a decrease in cholesterol and triglyceride levels in the blood and liver, a decrease in atherosclerotic lesion size, a decrease in body weight and in hyperglycemia, a reduction of fatty liver inflammation, and an improvement in liver function.

Abstract: A directional-control valve is typically comprised of a valve spool that slides linearly within a valve body. The valve body typically includes five internal ports, which are covered or exposed as the spool slides within the body. The typical five-internal-port architecture precludes certain combinations of port connectivity when the spool is in the center position. For example, when the spool is in the center position, providing connectivity between the actuator ports, while simultaneously providing fluid isolation of the supply and exhaust ports, is not directly achievable with a standard five-port architecture. This application describes three embodiments that enable the aforementioned port connectivity when the spool is in the center position.
Abstract: Embodiments of the present inventions comprise composites of polyurethane(s), osteoconductive matrix, and, optionally, a growth factor. Embodiments further comprise methods of making such composite and uses thereof. The osteoconductive matrix can be a tricalcium phosphate, bioglass, or the like, and can include particles that are surface modified. Growth factors can be provided in powder form, including bone morphogenic proteins such as rhBMP-2. A composition may be moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength and supports the in-growth of cells.
