Vaccines against prion disease eliciting a humoral immune response when administered mucosally are described. The vaccines comprise a prion protein, a prion protein fragment, or a non-amyloidogenic prion protein homolog and an adjuvant suitable for inducing a humoral immune response after mucosal administration. Suitable adjuvants include cholera toxin subunit B, heat-labile enterotoxin and aluminum hydroxide. Alternatively, the vaccine comprises a vector encoding a prion protein, fragment, or homolog in an attenuated Salmonella host. The vaccines can be used to prevent or treat prion disease in humans and other mammals.

A system to light a cavity 19 in an appliance. A source or light emitter 27 is mounted on a circuit board 32, so that the light emanating from said source or light emitter 27, is concentrated into a light beam using an optical collimator system 28 or in some cases a Fresnel arrangement; wherein the foregoing elements may be found outside a door 14, which allow access into the cavity; thus the light beam exiting the optical collimator 27 or Fresnel arrangement travels a distance though air between the optical collimator system 27 or Fresnel arrangement and the upper face of the light guide 29 which is placed on the door 14, the light guide 29 transports the luminous flux towards a notch which diverts said luminous flux directing into the cavity's 19 interior.
摘要:
Methods for treating anatomic tissue defects such as patent foramen ovale (PFO) generally involve positioning a distal end of an elongate catheter device at the site of the anatomic defect, exposing an expandable housing and energy transmission member out of the distal end of the catheter device, engaging the housing with tissues at the site of the anatomic defect, applying suction to the tissues via the housing to bring the tissues together; and applying energy to the tissues with the energy transmission member to substantially close the anatomic defect acutely. Apparatus generally include an elongate catheter body, a housing extending from a distal end of the catheter body for engaging tissues at the site of the anatomic defect, and an energy transmission member adjacent a distal end of the housing, the energy transmission member having at least one substantially planar surface.

Methods, devices and systems for treating patent foramen ovale (PFO) involve advancing a catheter device to a position in a heart for treating a PFO, bringing tissues adjacent the PFO at least partially together, and applying energy to the tissues to substantially close the PFO acutely. Catheter devices generally include an elongate catheter body, at least one tissue apposition member at or near the distal end for bringing the tissues together, and at least one energy transmission member at or near the distal end for applying energy to the tissues. In some embodiments, the tissue apposition member(s) also act as the energy transmission member(s). Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like.
摘要:
Methods and apparatus for treatment of layered tissue defects such as a patent foramen ovale provide for applying energy to tissues adjacent to the PFO with a closure device that substantially closes the PFO. Apparatus generally includes an elongate flexible member having a proximal end and a distal end and an energy transmission member deployable from the elongate flexible member. The energy transmission member applies energy to the layered tissue defect at a first position and a second position adjacent to the first position so as to substantially close the layered tissue defect along at least a portion of the defect. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating, direct heat energy, cryogenic or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device further include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.
摘要:
Apparatus and computing systems associated with cache sharing based thread control are described. One embodiment includes a memory to store a thread control instruction and a processor to execute the thread control instruction. The processor is coupled to the memory. The processor includes a first unit to dynamically determine a cache sharing behavior between threads in a multi-threaded computing system and a second unit to dynamically control the composition of a set of threads in the multi-threaded computing system. The composition of the set of threads is based, at least in part, on thread affinity as exhibited by cache-sharing behavior. The thread control instruction controls the operation of the first unit and the second unit.
摘要:
In general, in one aspect, the disclosure describes an apparatus that includes a memory device having a plurality of memory cells. An inverter is used to invert data and tag information destined for the memory device. A register is used to capture the inverted data and tag information. A write inverted value logic is used to determine when to enable writing the inverted data and tag information from the register to the memory device. When inverted data and tag information is written to a memory cell the memory cell is invalidated.
摘要:
A system for monitoring an unsupervised worker is provided that includes a plurality of sensors and a base station provided at the monitored location, a service provider server located remotely from the monitored location and operated by a third party service provider, and a computing device associated with a subscriber to the system. At least a portion of the sensed data is sent to and stored by the service provider server so that a report based thereon may, at the request of the system subscriber, be selectively generated and provided to the system subscriber. The computing device is also adapted to generate configuration data for one or more of the sensors and transmit the configuration data to the service provider server. The configuration data is then sent to the base station and used to control the operation of the sensors
