摘要:
The invention relates to a novel tyrosine kinase designated brk and the use of this tyrosine kinase in the development of diagnostic and therapeutic approaches to cancer. The novel tyrosine kinase was isolated from a human metastatic breast tumor using a PCR based differential screening approach and has the deduced amino acid sequence shown in SEQ ID NO:2.

Systems and methods for securing tissue including the annulus of a mitral valve. The systems and methods may employ catheter based techniques and devices to plicate tissue and perform an annuloplasty. Magnets may be used for guidance in deploying fasteners from a catheter. The fasteners are cinched with a flexible tensile member.

The invention is a method, triggering unit, and system for activating an oxygen scavenging composition at high speeds. The triggering unit includes a plurality of UV lamps that can operate at increased temperatures and have high output intensites from about 10 to 35 mW/cm2. The triggering unit can activate films at speeds from about 20 to 100 fps. Mercury amalgam lamps are useful in the practice of the invention. The invention also includes a UV dose management system and film tensioning system that facilitates triggering at high film speeds. The UV dose management system controls the amount of UV exposure that the film receives so that the oxygen scavenging rate of the activated composition can be controlled.

摘要:
Continuous-feed plasma treater systems are designed to treat continuous substrates, such as webs or films, by continuously feeding the substrates through an enclosure having a plasma discharge that alters the substrate's surface properties in some desirable fashion. The plasma discharges are generated by one or more electrode assemblies housed within the enclosure. In general, the plasma treater systems of the present invention have one or more cylinder-sleeve electrode assemblies and/or one or more cylindrical cavity electrode assemblies. A cylinder-sleeve electrode assembly comprises a cylinder electrode and a sleeve electrode positioned with its concave face facing and substantially parallel to the cylinder electrode to form an annular gap between the outer surface of the cylinder electrode and the inner surface of the sleeve electrode. The electrode assembly is adapted to be excited to generate a plasma within the annular gap to form a primary plasma discharge zone for exposure of the plasma to a substrate. A cylindrical cavity electrode assembly comprises (1) a cavity electrode, having a cylindrical bore and a wall slot running parallel to the cylindrical bore and exposing the cylindrical bore; (2) a cylinder electrode coaxially positioned within the cylindrical bore of the cavity electrode to form an annular gap between the outer surface of the cylinder electrode and the surface of the cylindrical bore, the annular gap forming a primary plasma discharge zone; and (3) a treater drum positioned adjacent to the wall slot of the cavity electrode. During operations, the substrate is translated past the wall slot by the treater drum and exposed to plasma species that are convected from the primary plasma discharge zone to the wall slot. Plasma treater systems of the present invention can be used (a) to treat substrates in an efficient cost-effective manner and (b) to produce treated substrates having superior surface properties as compared to those generated using prior-art systems, such as corona-type discharge systems.

摘要:
A minimally invasive method of performing annuloplasty. According to one aspect, a method for performing annuloplasty includes creating a first plication in the tissue near a mitral valve of a heart, using at least a first plication element, and creating a second plication in the tissue near the mitral valve such that the second plication is substantially coupled to the first plication.
摘要:
A heart retractor links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the heart retractor of the present invention. The retractor includes a plurality of flexible arms and a plurality of rigid arms as well as a surgery target immobilizing element. One form of the retractor can be used in minimally invasive surgery, while other forms of the retractor can accommodate variations in heart size and paracardial spacing.
