  • Patent number: 10751423
    Abstract: Disclosed are methods of treating cancer of the intraperitoneal cavity using compositions comprising nanoparticles without targeting agents. In addition, nanoparticles are described that comprise a highly toxic anticancer agent (e.g., an anticancer agent having an IC50 less than 1 nM) covalently bound via a linker to a triblock copolymer. Other nanoparticles that comprise Pt(IV) and an anticancer agent are also described. Also disclosed are nanoparticles comprising imaging agents non-covalently associated with a polymer, and methods of imaging cancer of the intraperitoneal cavity using compositions comprising nanoparticles without targeting agents.

  • Publication number: 20200238068
    Abstract: A transparent tubing is provided comprising a longitudinal axis having a center; an inner circumferential surface defining a fluid pathway therethrough for delivering a first medium having a first index of refraction m; an outer circumferential surface; at least one visual marker; and, at least one integrated lens disposed opposite from the at least one visual marker, the at least one integrated lens configured to direct light from the at least one visual marker for detecting a presence or an absence in the fluid pathway of a second medium having a second index of refraction n2, where n2 is different from the first index of refraction n1. A method of making transparent tubing having at least one integrated lens is also provided.

  • Publication number: 20180042483
    Abstract: A method, and corresponding system, can include identifying a plurality of wavelength spectral band components in hyperspectral image data, the spectral band components corresponding to mutually distinct sources of image contrast. An intensity image corresponding to each respective spectral band component can be calculated, followed by combining the respective intensity images to form an inter-band image based on the respective, mutually distinct sources of image contrast for each spectral band component. Intensity images can be hyperspectral or hyperdiffuse images. Hyperdiffuse imaging can be performed for each spectral band component identified using hyperspectral measurements. Spectral position and spectral width images corresponding to each spectral band component can be calculated and used to determine depth of features inside a surface of the target. Diffuse width images can be calculated from hyperdiffuse image data and used to determine depth.
