摘要:
Devices, compositions, and methods are described which provide a tubular nanostructure or a composite tubular nanostructure targeted to a lipid bilayer membrane. The tubular nanostructure includes a hydrophobic surface region flanked by two hydrophilic surface regions. The tubular nanostructure is configured to interact with a lipid bilayer membrane and form a pore in the lipid bilayer membrane. The tubular nanostructure may be targeted by including at least one ligand configured to bind to one or more cognates on the lipid bilayer membrane of a target cell.

A system is described generally for providing a structure or structures for altering water surface temperature. The system includes a holding vessel configured to hold water. The holding vessel has at least one wall coupled to a lowermost portion. The at least one wall extends above the water level and the lowermost portion is configured to be submerged. At least one conduit extends from the lower side of the holding vessel. The at least one conduit has a length extending to a depth at which a property of water at the depth is substantially different from that of the water at the surface.

Methods and related systems for modulating neural activity by blocking conduction in peripheral neural structures with thermal stimuli are disclosed. Methods and systems for reversing effects of thermal blocking stimuli and/or for producing substantially permanent conduction block are also disclosed.
摘要:
The present disclosure is directed to a medical device comprising a dispenser adapted to dispense a tissue sealant or one or more precursor compounds, the dispenser being operably coupled to a grasper. Furthermore, the medical device comprises a dispenser adapted to dispense a tissue sealant or one or more precursor compounds thereof, the dispenser being operably coupled to a surgical cutter. Additionally or alternatively the medical device can include an actuation mechanism, whereby the dispenser dispenses the tissue sealant or one or more precursor compounds at a surgical cutting site or in a proximity thereof.

A method composition and system respond to ionizing radiation to adjust biological activity. In some approaches the ionizing radiation is X-ray or extreme ultraviolet radiation that produces luminescent responses that induce biologically active responses.
摘要:
One aspect can relate to detecting a prescence of an at least one chemical, compound, or biological material contained in an at least some matter of an at least a portion of an at least one individual based at least partially on addition of an at least one chemical identifying additive to the at least some matter of the at least the portion of the at least one individual based at least partially on a generation of an at least one induced X-ray fluorescing photon within the at least one chemical identifying additive responsive to a single input energy event in which an at least some input energy is being applied proximal to the at least one chemical, compound, or biological material contained in the at least some matter of the at least the portion of the at least one individual.
摘要:
One aspect relates to selective X-ray fluorescence visualization, imaging, or information providing of an at least some matter of an at least a portion of an individual that at least partially indicates an at least one differentiatable element composition of the at least some matter of the at least the portion of the individual, wherein the selective X-ray fluorescence visualization, imaging, or information providing selectively displays a first at least one differentiatable element composition of the at least some matter of the at least the portion of the individual at least partially responsive to a first single input energy event based at least partially on an at least some first input energy being applied to the at least some matter of the at least the portion of the individual, and the selective X-ray fluorescence visualization, imaging, or information providing selectively displays a second at least one differentiatable element composition of the at least some matter of the at least the portion of the individual that is interpretable distinctly from the first at least one differentiatable element composition.
摘要:
One aspect relates to optically detecting an at least one scintillated viewable and/or visible photon that has been converted from the at least one induced X-ray fluorescing photon. The aspect can also relate to optically detecting an at least one scintillated viewable and/or visible photon that has been converted from the at least one induced X-ray fluorescing photon.
摘要:
Methods, apparatuses, computer program products, devices and/or systems are described that include a blood vessel sleeve that is custom-fitted for the outside of a blood vessel at least partly based on anatomical blood vessel data from an individual.
摘要:
Embodiments include a surgical device and a method. An embodiment of the surgical instrument includes at least one grasping jaw, the at least one grasping jaw being adapted to deliver surgical staples by a force generated from a force generator mechanism that is contained within the at least one grasping jaw or is in a proximity to the at least one grasping jaw. Another embodiment includes at least one grasping jaw, at least one delivery mechanism adapted to deliver surgical fasteners, the delivery mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical fasteners containing at least one shape-transforming material, at least one sensor, at least one chemical tissue sealant and at least one cutter. A method includes: grasping a body tissue with at least one grasping jaw, adjusting a configuration of the grasping in response to a signal or a datum or an image, and releasing a surgical staple/fastener in response to the signal, datum or image.
