摘要:
A stent is provided with a drug-eluting layer disposed on at least a portion of its surface, wherein the drug-eluting layer comprises an endosome-disrupting agent and a pharmaceutical agent. In an embodiment, the endosome-disrupting agent, when taken up through endocytosis into living cells, causes lysis of endosomes containing the endosome-disrupting agent. The pharmaceutical agent can accompany the endosome-disrupting agent into the living cells.

Disclosed are methods to prepare a specimen for microanalysis, the specimens so prepared, and methods to analyze the specimens by atom probe microscopy. The specimens are prepared by embedding a specimen within an electrically conductive matrix to yield an embedded specimen; and then forming regions on the embedded specimen into shapes suitable for microanalysis by an atom probe.

A method of making a die body configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body and the step (II) of predetermining an upstream slot width W1 of the die body such that the upstream slot width W1 is optimized while a root of each die pin includes a section modulus within a predetermined section modulus range. The method still further comprises the step (III) of predetermining a slot length L such that a pin stress is within a predetermined pin stress range.
摘要:
A drug-eluting endoprosthesis that includes a bioerodible metal portion and a therapeutic agent. In some aspects, the endoprosthesis includes a plurality of discrete deposits and a plurality of overlying layers each overlying one of the plurality of discrete deposits. Each discrete deposit includes one or more therapeutic agents and each overlying layer includes one or more bioerodible metals. In other aspects, the bioerodible metal portion includes at least two bioerodible metal regions having different electronegativities. The at least two bioerodible metal regions being in electrical contact with each other. The bioerodible metal erodes in a physiological environment to release the therapeutic agent.
