摘要:
Certain biomarkers and biomarker combinations are useful in a qualifying hepatocellular carcinoma status in a patient. A diagnostic methodology employing these biomarkers and combinations can distinguish between hepatocellular carcinoma and chronic liver disease, for example.

A gas compressor unit according to the invention includes a single gas desiccant bed and condenser (which is inactive during the compression stage) inserted into the gas flow path of the compression cycle. In the case of a multistage compressor, the single gas desiccant bed is inserted between preferably the first and second stages. Moisture absorbed into this bed is periodically removed by exposing the bed to a regeneration cycle. The regeneration cycle employed is based on the closed re-circulation of gas present in the compressor and the desiccant bed itself, as well as other gas present in the re-circulation loop when the unit suspends delivery of compressed gas. Moisture removed from the desiccant bed is condensed and preferably evaporated into the environment through a semipermeable membrane. The motor and motor controller are located with the compressor in a common casing to minimize electromagnetic emissions.

A compressor for natural gas is made in a format suitable for mounting on a wall or upright support at a residential location. This permits refilling of the gas reservoir of a gaseous-fueled motor vehicle parked at the residence. The wall-mounted appliance has vibration isolation supports to minimize transmission of noise into the residence. It has a ventilation and air circulation system that allows it to test for the presence of flammable gas both leaking from the appliance and present in the adjacent ambient environment, e.g. a garage.

A fluid control method includes providing fluid flow through a conduit having a pressure sensitive shutdown valve; driving an electrical power generator with the turbine wheel and delivering electrical power to a storage battery which in-turn powers the components of the system. The method further includes: detecting turbine RPM; calculating volume flow rate from the RPM value and conversion factors input to a computer program. Next, it is determined if average or peak flow rates exceed set point values and creating a shut down signal if it is true so as to close the shutdown valve. A fluid pressure delta is therefore established across the shutdown valve and it is only opened when fluid pressure equilibrium is restored across the valve after break or leak repair and after slowly refilling the downstream system.

The present invention relates to therapeutic methods for preventing or reducing neurological events utilizing a glycosaminoglycan and a serpin, including complexes and conjugates thereof. Methods of the present invention may be advantageous for preventing or reducing neurological events prior to, or during medical or surgical procedures, and after a neurological event. In particular, the present invention deals with neurological events associated with the generation of emboli that can lodge in the brain and/or cerebral circulation during cardiac surgery.
摘要:
The invention relates generally to a coating composition for a polymeric surface, methods for coating a polymeric surface, methods for preparing coated medical devices, polymeric surfaces coated with the coating composition, and medical devices comprising the coating composition. In particular, a coating composition for association with a polymeric surface, preferably a polymeric surface of a medical device, is described comprising a cross-linked basecoat displaying a plurality of active groups in association with a serpin or serpin derivatives, wherein the serpin or serpin derivatives are not substantially cross-linked with other serpin or serpin derivatives.

A pivoting cradle apparatus for capturing an aircraft wheel on an aircraft tug includes a cradle sized for holding the wheel, mounted on at least one pivot block and configured to pivot between a wheel loading position and a wheel retaining position. A latch mechanism is disposed under the cradle, biased to swing into an upright position wherein it seats in a notch on the cradle, locking the cradle in the wheel retaining position. A latch release mechanism is configured to urge the latch out of the upright position, and when it does so, the latch slides along the underside of the cradle as the cradle pivots down. into the wheel loading position.

An artificial placenta oxygenating device for use with an infant is provided. The device comprises a first layer comprising a gas permeable membrane; and a second layer comprising a vascular network that permits circulation of fluid therethrough, wherein a portion of the gas permeable membrane is attached to and covers the vascular network, wherein the vascular network comprises an inlet that permits fluid flow into the vascular network and an outlet that permits fluid to flow out of the vascular network and wherein the inlet and outlet are positioned so that fluid flows through the vascular network and in contact with the gas permeable membrane to permit gas exchange to occur. Assemblies comprising a plurality of single artificial placenta devices is also provided.
