The present invention concerns a method for predicting the potential for aggressive growth and/or the risk to progress to high grade cancer for tumors in cell based detection procedures. In one aspect the invention concerns the detection of overexpression of cyclin-dependent kinase inhibitor gene products as a tool for predicting the progression risk and/or potential for aggressive growth of tumors. In a second aspect the invention concerns predicting the progression risk and/or potential for aggressive growth in tumors on the basis of the simultaneous co-detection of the presence of overexpression of cyclin-dependent kinase inhibitor gene products together with the expression of markers for active cell proliferation. Further the invention concerns preparations of probes for diagnosis namely for predicting the progression risk and/or the potential for aggressive growth of tumors.
摘要:
Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.
摘要:
A double row roller bearing which has an outer and inner bearing ring and ball rollers, which have lateral faces and are arranged next to each other in rows, arranged between the bearing rings. The rollers roll in raceways incorporated into the inner face of the outer bearing ring and outer face of the inner hearing ring. The raceways run in parallel and have pressure angle axes that are pitched at a pressure angle relative to a bearing radial axis. The rollers have a distance relative to each other which excludes mutual frictional contacts. For this purpose, the distance of the pressure angle axes of the raceways is enlarged and both rows of rollers are guided in separate bearing cages, while the raceway of the rollers of the row with the larger reference circle arranged on the inner bearing ring has a one-sided axial extension using the distance.
摘要:
Pixel circuits, capable of operating in either “snapshot” or “rolling integration” mode, and compatible with a conformal photodiode coating. Preferred embodiments of the present invention are compatible with these coating materials, as well as others, including amorphous Silicon. The preferred pixel circuits includes additional transistors not provided in prior art pixel circuits to divert leakage current away from integration nodes when not integrating, to reset the integration node, and to buffer and select the integrated voltage.

A connector for attaching a flexible tube to a fluid passage of another object includes a housing and a connector port on the body. The connector port is sized and shaped for connecting the connector port in fluid communication with the fluid passage of the object. The connector includes a tube port projecting from the body. The tube port is adapted for fluid communication with the connector port and is sized and shaped for being received in an end of the flexible tube to establish fluid communication with the flexible tube. The tube port includes a tube retainer that projects from the body toward the tube port. The retainer has an engaging end portion disposed in relation to the tube port to engage the flexible tube when the tube port is received in the flexible tube. The flexible tube is restrained from lateral movement with respect to the tube port.

A process for determining the position and velocity of an object is disclosed. The process comprises: -generating a first burst of pulses at a first pulse repetition frequency and subsequently receiving a first set of signals characteristic of the range and velocity of the object; -generating a second burst of pulses at a second pulse repetition frequency and subsequently receiving a second set of signals characteristic of range and velocity of the object; -generating a first data set representative of range and corresponding velocity values from the first set of signals; -generating a second data set representative of range and corresponding velocity values from the second set of signals; -summing a magnitude of a signal strength from each of the first and second data sets at corresponding range and velocity values; and, -comparing the magnitude of the summed signal strengths to a threshold value.

The invention is directed to a process for the making of a product out of laminated composite material. The process in general comprises preforming at least one layer of material such that it corresponds to a surface of a part; applying layers of fibers to the preformed layer of material; and bonding the fibers by a resin to form a laminated composite material.
