Affibody polypeptides that specifically bind to B7-H3 are provided. Exemplary anti-B7-H3 affibodies are provided. The affibody polypeptides specifically recognize and bind to B7-H3 with high affinity. The affibodies can be conjugated to contrast agents, including without limitation microbubbles for contrast-enhanced ultrasound imaging

A bubble manufacturing container of the present invention includes: a container body having an opening portion; and a rubber stopper provided on the opening portion of the container body. The rubber stopper is constituted so that the bubbles 1 of an inside of the container body are able to be taken by piercing an injection needle. It is preferred that the bubble manufacturing container has a fastening portion provided on the rubber stopper, having an opening and sealing the container body with the rubber stopper. Furthermore, it is preferred that the container body mounts a weight portion.

Microresonator structures including a top polymer film layer, a bottom polymer film layer, and a smart hydrogel structure sandwiched between the polymer film layers. An ultrasound resonator cavity having a resonance frequency is defined between the top and bottom polymer layers, and the smart hydrogel structure is configured to provide a change in height to the ultrasound resonator cavity due to volumetric expansion or contraction of the smart hydrogel structure, in response to interaction of the smart hydrogel structure with one or more predefined analytes in an in vivo or other environment. Related methods of use for determining the presence or concentration of a given target analyte, as well as methods of fabricating such microresonator structures are also described.

A composition, and method thereof, for stabilizing a fluorocarbon emulsion includes phosphatidylcholine, phosphatidylethanolamine-PEG, and a cone-shaped lipid.

Provided herein are improved methods for preparing phospholipid formulations including phospholipid UCA formulations.

Provided herein are improved methods for preparing phospholipid formulations including phospholipid UCA formulations.

Embodiments disclosed herein relate to internal combustion engines, combustion systems that include such internal combustion engines, and controls for controlling operation of the combustion engine. The internal combustion engine may include one or more mechanisms for injecting fuel, air, fuel-air mixture, or combinations thereof directly into one or more cylinders, and controls may operate or direct operation of such mechanisms.

Gas vesicles, protein variants and related compositions methods and systems for singleplexed and/or multiplexed ultrasound imaging of a target site in which a gas vesicle provides contrast for the imaging which is modifiable by application of a selectable acoustic collapse pressure value of the gas vesicle.

A method for preparing a suspension of “size-controlled” gas-filled microvesicles by microfluidic manufacturing techniques, which comprises using a gaseous flow comprising a first gas having high solubility in water and a second gas having low 5 solubility in water.

Abstract: The present invention provides a core-shell micro-particle comprising a biodegradable polymer with at least two or more surface cavities. The present invention also provides use of the core-shell micro-particle in drug delivery, contrast enhancement, subharmonic imaging enhancement, theranostics, and/or any combination of the aforementioned applications.
