    Abstract: Some methods of analyzing one or more brain lesions of a patient comprise, for each of the lesion(s), calculating one or more lesion characteristics from a first 3-dimensional (3D) representation of the lesion obtained from data taken at a first time and a second 3D representation of the lesion obtained from data taken at a second time that is after the first time. The characteristic(s) can include a change, form the first time to the second time, in the lesion's volume and/or surface area, the lesion's displacement from the first time to the second time, and/or the lesion's theoretical radius ratio at each of the first and second times. Some methods comprise characterizing whether the patient has multiple sclerosis and/or the progression of multiple sclerosis in the patient based at least in part on the calculation of the lesion characteristic(s) of each of the lesion(s).

    Abstract: In some aspects, this invention provides a method of making a bone marrow-derived tissue-specific stem cell proliferation, expansion, isolation and rejuvenation extracellular matrix. In other aspects, this invention provides a method of making a tissue-specific fibroblast-derived stem cell differentiation extracellular matrix. Also provided are methods of using such a cell-derived preservation or differentiation matrices to induce tissue-specific differentiation of pluripotent cells, repair damaged tissue, and treat a subject having a physiologic deficiency using the same.

    Abstract: The hiccup relieving apparatus includes a tube with a first end having a mouthpiece, a second end for immersion in water or other potable liquid in a container, and an obstruction in the tube between the first end and the second end. The obstruction requires an adult user, using the mouthpiece, to produce a threshold suction of at least 20 cm of water before water can flow from the water in the water container, through the tube, through the mouthpiece, and to the user. The obstruction can take the form of a threshold valve in the tube, a sized orifice in the immersed end of the tube, or a wad of cellulosic material in the tube.

    Abstract: Methods, apparatuses, systems, and implementations for creating 3-dimensional (3D) representations exhibiting geometric and surface characteristics of post-contrast brain lesions are disclosed. 3D MRI images of the brain may be created and acquired. After administration of a contrast substance, brain lesions and other abnormalities may be identified and isolated from the 3D MRI images, with each lesion serving as a region of interest (ROI). 3D region of contrast enhancement images may be created from segmented 3D MRI images and different regions of contrast enhancement of the brain lesion may be depicted. Saved regions of contrast enhancement may be converted into stereolithography format, maximum intensity projection (MIP) images, and/or orthographic projection images. Data corresponding to these resulting 3D region of contrast enhancement images may be used to create 3D printed models of the isolated region of contrast enhancement using 3D printing technology. Analysis of the 3D brain region of contrast enhancement images and the 3D printed region of contrast enhancement models may enable a more efficient an accurate way of determining brain lesion risk factors and effective treatment regimes.

    Abstract: Provided herein are block copolymers comprising a hydrophilic polymer segment and a hydrophobic polymer segment, wherein the hydrophilic polymer segment comprises a polymer selected from the group consisting of: poly(ethylene oxide) (PEO), poly(methacrylate phosphatidyl choline) (MPC), and polyvinylpyrrolidone (PVP), wherein the hydrophobic polymer segment comprises wherein R′ is —H or —CH3, wherein R is —NR1R2, wherein R1 and R2 are alkyl groups, wherein R1 and R2 are the same or different, wherein R1 and R2 together have from 5 to 16 carbons, wherein R1 and R2 may optionally join to form a ring, wherein n is 1 to about 10, and wherein x is about 20 to about 200 in total. Also provided are pH-sensitive micelle compositions for therapeutic and diagnostic applications.
