摘要:
The invention provides a method of targeting a drug to areas of hypoxic and/or ischemic tissue within the body in which the desired drug species is linked to a non-cytotoxic bioreductive carrier. Also provided by the invention are novel bioreductive conjugates comprising a non-cytotoxic bioreductive moiety with linked-thereto at least one therapeutic agent. The compounds of the invention are particularly suitable for the treatment of rheumatoid arthritis and other arthritic conditions, diabetes, atherosclerosis, stroke, sepsis, Alzheimer's disease and other neurological disorders, cancer, kidney disease, digestive diseases, liver disease, chronic periodontitis or ischemia following tissue transplantation.
摘要:
A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

Two new burs to be used in dentistry applications. The two burs are used one after the other to create a natural anatomy in restorations of teeth. One of the burs also reduces the need for anesthetic by providing for minimal contact with the dentin while removing the enamel when cutting into a tooth.

A reinforcement bar combination for a direct dental bridge, the reinforcement bar combination including: first and second elongate bars, each of the first and second elongate bars contacting a single occlusal preparation formed in a single abutment tooth and each of the first and second elongate bars having an end positioned on a central pad of a third elongate bar to form a reinforcement scaffold. The first elongate bar is a first elongate torque bar that is optionally bent. The second elongate bar is a second elongate torque bar that is optionally bent. The third elongate bar is a proximal bar including a central planar pad bound by a perimeter, a coronal facing surface and an apical facing surface, a first insertion arm extending in a mesial direction from the perimeter of the pad, a second insertion arm extending in a distal direction from the perimeter of the pad; a first vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad; a second vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad. A method of using of the reinforcement bar combination to produce a direct dental bridge is also described.

Various means are provided which enable a user to individualize the appearance of a firearm and further enhance visibility of the various elements comprising the firearm in low light. More particularly, the firearm may comprise a serialized receiver and at least one of a barrel, upper receiver, grip, hand guard, and buttstock defining firearm accessories. A light source, means for distributing the light, a power source, and means for activating the light source are then provided to permit a user to selectively illuminate any of the elements comprising the firearm. The light source and means for distributing the light source may, for example, be disposed on a skin adhesible the serialized receiver and firearm accessories, on a clip slideably mateable with any of the serialized receiver and firearm accessories, or even integrated directly into the body of any of the firearm accessories and serialized receiver.

A gas bubble agitated mixing system for viscous fluids comprising: a container (1) in which a viscous fluid (2) may be held; one or more gas pipes (6), each gas pipe having an outlet (8) arranged to introduce gas bubbles (9) into the base region of the container (1), said gas bubbles (9) being of a size suitable to agitate the viscous fluid (2). The system also comprises a moveable carrier arm (4) upon which said one or more gas pipe outlets (8) are mounted; and wherein the movement of the carrier arm (4) causes the position at which each outlet (8) introduces gas bubbles (9) into the container (1) to vary over time.

Methods, apparatus and systems for detecting charged particles and obtaining tomography of a volume by measuring charged particles including measuring the momentum of a charged particle passing through a charged particle detector. Sets of position sensitive detectors measure scattering of the charged particle. The position sensitive detectors having sufficient mass to cause the charged particle passing through the position sensitive detectors to scatter in the position sensitive detectors. A controller can be adapted and arranged to receive scattering measurements of the charged particle from the charged particle detector, determine at least one trajectory of the charged particle from the measured scattering; and determine at least one momentum measurement of the charged particle from the at least one trajectory. The charged particle can be a cosmic ray-produced charged particle, such as a cosmic ray-produced muon. The position sensitive detectors can be drift cells, such as gas-filled drift tubes.

A method for creating composite images of multiple objects using standard commodity graphics cards is provided that eliminates the need for expensive specialty graphics hardware for generating real-time renderings of the composite images. After the desired composite image and the objects contained in the composite image are identified, a volume rendered image of a first object is obtained. In addition, at least a first geometric representation and a second geometric representation of a second object based upon a desired composite image of the first and second objects are generated. These geometric representations are preferably polygonal representations. The volume rendered image and the geometric representations are used to create a plurality of composite image components. Each composite image component contains at least one of the volume rendered image, the first geometric representation and the second geometric representation. The composite image components are blended to create the desired composite image.

Systems and apparatuses for hanging articles while avoiding removal and/or damage to pre-installed supports and even surfaces are provided. In an embodiment, a device comprises a body configured to mechanically rest on or grip a portion of the pre-installed support, or even to be forcibly strapped to the pre-installed support. Additionally, a linking member, such as a clip, groove, channel, or hook, may be disposed along the body to join an article to the support. In practice, a plurality of devices may be applied to a variety of different types of head rails and other supports to join, for example, curtains to the head rail or other support, whether by forcibly gripping such curtains or supportively receiving a rod fitted with curtains.

A method and apparatus for self-assembling a part on a substrate are disclosed herein. In some embodiments, a method includes placing a substrate having a first binding site capable of generating a first magnetic field and having a first shaped surface with a first droplet conformably disposed thereon into a first fluid; placing a part having a second binding site capable of generating a second magnetic field and having a second shaped surface with a second droplet conformably disposed on the second shaped surface into the first fluid; and attracting the part towards the first binding site such that an equilibrium is formed between an attractive force and a repulsive force such that the part is free to rotate about the first binding site to minimize the repulsive force when the first and second shaped surfaces rotate into an alignment causing the part to aligned with the first binding site.
