摘要:
The present invention is directed to novel tricyclic heterocycles of structural formula I which are inhibitors of the dipeptidyl peptidase-IV enzyme and which are useful in the treatment or prevention of diseases in which the dipeptidyl peptidase-IV enzyme is involved, such as diabetes and particularly Type 2 diabetes. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which the dipeptidyl peptidase-IV enzyme is involved.

Described herein are endoscopic staplers used to apply one or more fasteners to body tissue. In one embodiment, a fastener-applying device, which is preferably a stapler, is passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed staplers allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver staples for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications are formed, medical devices may optionally be coupled to the plication(s) for retention within the stomach.

摘要:
A reductant delivery unit (10) is provided for selective catalytic reduction (SCR) after-treatment for vehicles. The unit includes a solenoid fluid injector (10) constructed and arranged to be associated with an exhaust gas flow path (14) upstream of a SCR catalytic converter (17). The fluid injector has a fluid inlet (13) and a fluid outlet (15) with the fluid inlet being constructed and arranged to receive a source of urea solution and the fluid outlet being constructed and arranged to communicate directly with the exhaust flow path so as to control injection of urea solution into the exhaust gas flow path. An interface (24) is constructed and arranged to couple the fluid injector to the gas flow path. The interface defines a thermal barrier constructed and arranged to decoupled a body of the injector from exposure to heat in the exhaust gas flow path.
摘要:
A system and method provide comprehensive and highly automated testing of vulnerabilities to intrusion on a target network, including identification of operating system, identification of target network topology and target computers, identification of open target ports, assessment of vulnerabilities on target ports, active assessment of vulnerabilities based on information acquired from target computers, quantitative assessment of target network security and vulnerability, and hierarchical graphical representation of the target network, target computers, and vulnerabilities in a test report. The system and method employ minimally obtrusive techniques to avoid interference with or damage to the target network during or after testing.
摘要:
A marine riser assembly having a first tubular member having an external surface with a plurality of first axially spaced formations, a second tubular member having an external surface with a plurality of second axially spaced formations thereon, a segmented ring in surrounding relationship to the first and second tubular members, the segmented ring having an inner surface with a plurality of formations engageable with the formations on the first and second tubular members, the engageable formations serving to urge the first and second tubular members toward each other when the segmented ring is subjected to radially inwardly directed compressive forces, a sleeve in surrounding relationship to force the engageable formations together and a seal assembly for sealing against external and internal pressure.
摘要:
A method of forming an elongate composite product wherein a composite body formed of an internal billet and an external sleeve is assembled, the interior periphery of the sleeve being complimentary to the exterior periphery of the billet, the composite body then being formed as by extruding into an elongate product having an inner core and an outer sheath.
摘要:
Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

The present invention provides an improvement (20) in a Davenport® automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism (26) associated with the stationary spindle (22). The mechanism includes mating frusto-conical first and second surfaces (28, 31) on the spindle and tool holder, and a multi-lead threaded connection (32) between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism (33) that allows the axis (x2-x2) of the tool to be aligned with the axis (x1-x1) of a spaced rotatable spindle. This adjustment mechanism includes a base member (34), an adjustment member (35), and a locking mechanism (37) for selectively holding the adjustment member in the desired position relative to the base member.
