摘要:
A disposable device for tissue cauterization, including a generally electrically insulating housing assembly and a generally electrically conducting elongated assembly. The housing assembly includes a barrel having a cylindrical aperture formed therethrough, a grip extending from the barrel, a trigger slidingly connected to the barrel, a spring connected to the trigger, and an end plug positioned adjacent the proximal end of the barrel. The elongated assembly includes a hollow elongated outer cylinder disposed within the barrel and extending from the distal end, a generally hollow elongated inner cylinder slidably disposed within the elongated outer cylinder and extending to snugly engage the end plug, and bipolar forceps operationally connected to the distal end of the elongated inner cylinder and defining a leaf spring. Actuation of the trigger urges the inner cylinder to slide in a proximal direction relative to the outer cylinder, urging the bipolar forceps partially into the outer cylinder and closer together.

Shroud assembly for use in a turbine, having an outer shroud having a side proximate to flow of operative fluid of the turbine, the side having a boss and an outer shroud aperture extending through the boss. An inner shroud is located between the side of the outer shroud proximate to the flow of operative fluid and the operative fluid flow of the turbine, the inner shroud having an inner shroud aperture which is dimensioned to fit over the boss.

A streamlined method for purifying alpha-1-antitrypsin (AAT) from an AAT-containing protein mixture, such as a Cohn fraction IV precipitate, is provided. In the method of the invention, contaminating proteins are destabilized by cleavage of disulfide bonds with a reducing reagent, such as a dithiol, which does not affect AAT. The destabilized proteins are then preferentially adsorbed on a solid protein-adsorbing material, without the addition of a salt as a precipitant. Separation of the solid adsorbent from the solution leaves a purified AAT solution that is directly suitable for chromatographic purification, without the need for extensive desalting as in prior art processes. A process incorporating this method, which provides pharmaceutical grade AAT in high yield on a commercial scale, is also described.

Embodiments of the present invention comprise a system for carrying golf clubs on the front end of a bicycle by dividing the clubs between two enclosures: one to the left of the bicycle's front fork and one to the right thereof. Another Embodiment comprises the aforementioned system in combination with a bicycle having tires with a diameter in excess of 3.0 inches. The bicycle in combination with the system can be rented to golfers in place of golf carts to transport the golfer around a course.

Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are liquid formulations which deliver a variety of therapeutic agents, including but not limited to rapamycin, to a subject for an extended period of time; liquid formulations which form a non-dispersed mass when placed in an aqueous medium of a subject; non-dispersed mass-forming liquid formulations which form a gel or gel-like substance in an aqueous medium; liquid formulations, comprising a therapeutic agent and a plurality of polymers; and methods for delivering therapeutic agents to a subject for an extended period of time using the liquid formulations. The liquid formulation may be placed in an aqueous medium of a subject, including but not limited to via intraocular or periocular administration, or placement proximate to a site of a disease or condition to be treated in a subject. A method may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, or age-related macular degeneration, or wet age-related macular degeneration in a subject. The liquid formulations may comprise rapamycin or other therapeutic agents.

Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are solid drug delivery systems and methods for providing extended delivery of therapeutic agents to such tissues. A solid drug delivery system may be placed in a subject, including but not limited to placement between the sclera and the conjunctiva or transscleral placement. Described methods may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, age-related macular degeneration, or wet age-related macular degeneration in a subject. The solid drug delivery devices may comprise rapamycin or other therapeutic agents. Also described are methods of treating ocular diseases or disorders by administering an antiproliferative agent, including but not limited to rapamycin, proximal to an ocular device.

The present invention provides a synthesizer having an efficient lock detect signal generator, an extended range VCO that can operate within any one of a plurality of adjacent characteristic curves defined by a plurality of adjacent regions, and a divide circuit implemented using only a single counter along with a decoder. This allows for a method of operating the synthesizer, methods of establishing or reestablishing a lock condition using the extended range VCO, and a method of designing a plurality of divide circuits which each use the same single counter and each use a different decoder.
摘要:
A balanced wire resistor has two interconnected windings with different temperature coefficients. The electrical resistance of the wire resistor is determined only by the resistance values of the two windings. In a process for the production of the wire resistor, the wire length of a first winding of the newly to be wound wire resistance is calculated by using the measured wire length, as well as measured resistance values of the previously wound wire resistor. The wire length of a second winding of the newly to be wound wire resistance is determined by using the two measured wire lengths of the two windings, as well as measured resistance values of the previously wound wire resistor.

A new and distinct Vaccinium spp. cultivar named ‘WINTER BELL’ is disclosed, characterized by a semi-upright plant habit, vigorous growth and semi-deciduous habit in Florida. The new variety shows tolerance for a wetter soil conditions. Fruit yield is exceptionally high, with fruit ripening early, with first harvest in mid to late March. Fruit is somewhat bell-shaped with good size and an attractive waxy coating. The new variety is a Vaccinium, and is normally used as an ornamental garden or landscape plant.
摘要:
Particles emitted by radio-isotopic by-products of nuclear fission are used as a power source at the cathode of a magnetron system. Particles include high energy electrons having a large associated EMF. In the system a radial electrical vector E, between the cathode and anode, interacts with an axial magnetic vector B vector to produce an E×B force that rotates the particles about the system axis. These emissions are within a set range of velocities. The angular velocity and geometry of a rotating field, known as a space charge wheel (SCW), may be modulated by an external RF inputs to cavities of an anode block and the use of concentric biasing grids between the cathode and anode block. The SCW induces LC values into cavities of the anode, exciting them and producing electrons resonance which may be used to generate power.
