Hydroamination: direct addition of amines to alkenes and alkynes.

Recent advances in transition metal catalyzed oxidation of organic substrates with molecular oxygen.

Methods are provided for inhibiting stenosis following vascular trauma or disease in a mammalian host, comprising administering to the host a therapeutically effective dosage of a therapeutic conjugate containing a vascular smooth muscle binding protein that associates in a specific manner with a cell surface of the vascular smooth muscle cell, coupled to a therapeutic agent dosage form that inhibits a cellular activity of the muscle cell. Methods are also provided for the direct and/or targeted delivery of therapeutic agents to vascular smooth muscle cells that cause a dilation and fixation of the vascular lumen by inhibiting smooth muscle cell contraction, thereby constituting a biological stent.

Therapeutic inhibitor of vascular smooth muscle cells

Alcohol oxidations are typically performed with stoichiometric reagents that generate heavy-metal waste and are usually run in chlorinated solvents. A water-soluble palladium(II) bathophenanthroline complex is a stable recyclable catalyst for the selective aerobic oxidation of a wide range of alcohols to aldehydes, ketones, and carboxylic acids in a biphasic water-alcohol system. The use of water as a solvent and air as the oxidant makes the reaction interesting from both an economic and environmental point of view.

Green, catalytic oxidation of alcohols in water

The present invention provides a surgical stapling apparatus and a buttress, i.e. pledget, for use in the surgical stapling apparatus, which buttress provides sealing for hemostasis and pneumostasis, and which buttress includes a continuous projection, or a plurality of projections, for cooperation with guide channels for thereby attaching the buttress to the staple cartridge or anvil in a releasable pressure fit relationship.

A trilobal or quadrilobal fiber formed from thermoplastic polymers, said fiber having a cross-section comprised of a central core having three or four T-shaped lobes, the legs of each intersecting at the center of said core such that the angle between the legs of adjacent lobes is from about 80° to about 130°.

Filaments having trilobal or quadrilobal cross-sections

This invention relates to a fiber comprising a major amount of a continuous phase comprising one or more melt processible polyesters of fiber forming molecular weight, and a minor amount of one or more polyolefins non-uniformly dispersed in said continuous phase such that the concentration of polyolefins at or near the surface of said fiber is greater than the concentration of polyesters at or near the surface of said fiber, and a process for preparing said fiber.

Fibers and filters containing said fibers

This invention relates to novel copolymers containing carbonate repeat units and ester repeat units.

Medical devices fabricated totally or in part from copolymers of recurring units derived from cyclic carbonates and lactides

This invention relates to medical devices formed totally or in part from homopolymers or copolymers comprising recurring carbonate moieties.

Medical devices fabricated from homopolymers and copolymers having recurring carbonate units

This invention relates to an implantable medical device capable of encouraging cellular growth and regeneration of function fabricated totally or in part from one or more bioresorbable polymers, as for example bioresorbable homopolymers derived from the polymerization of alpha-hydroxy carboxylic acids, where at least one of the polymers has an average molecular weight of from about 234,000 to about 320,000 as measured by gel permeation chromatography.
