摘要:
Hair follicle bulge region/LLP region CD34(+) MeSCs can be isolated from mammalian skin bearing hair follicles. These cells are multipotent and retain the ability to differentiate into cells of neural crest lineage, including glia-like cells that express the glial marker Gfap, and are able to express myelin basic protein, and to remyelinate naked (unmyelinated or demyelinated) neuronal processes with a functional, dense myelin sheath. These cells of neural crest lineage can be used to produce a dense myelin sheath on neurons which lack myelin due to genetic defect, trauma, toxin, infection, or disease process. Therefore, embodiments of the invention provide methods for preparing such cells, the cells themselves and compositions containing the cells, as well as methods for using the cells.

A device disclosed herein includes a tubular member which is flexible and configured to receive ultraviolet (UV) light from a UV illumination coupler. The tubular member contains a lumen defining a longitudinal interior space within the tubular member, a tubular body bounded by an inner wall defining an outer boundary of the lumen and an outer wall defining an outer surface of the tubular member, at least one optical fiber disposed outside of the interior space not parallel to an axis of the lumen and adapted to receive the UV light from the UV illumination coupler, and a protective component adapted to prevent substantively all of the UV light emitted from the optical fiber from exiting the outer wall. Methods for producing and using such devices are also disclosed herein.

摘要:
Techniques for metal enhanced fluorescence include determining a calibration curve that relates concentration of a particular analyte to at least one of intensity or lifetime of fluorescent emissions at a plasmonic substrate in response to incident light, for a plurality of known concentrations of the particular analyte mixed with a reagent. The reagent comprises a detection molecule. A concentration of the particular analyte in a vicinity of a cell in a sample is determined directly from the calibration curve and measurements, in response to the incident light, of at least one of intensity or lifetime of fluorescent emissions at the plasmonic substrate in contact with the cell and reagent.

Described are steroidal C-17 benzoazoles, pyrimidinoazoles (azabenzoazoles) and diazines. Methods for their synthesis are also described, which include methods having a step of nucleophilic vinylic “addition-elimination” substitution reaction of 3β-acetoxy-17-chloro-16-formylandrosta-5,16-diene or analogs thereof and benzoazole or pyrimidinoazole nucleophiles and methods having a palladium catalyzed cross-coupling reaction of 17-iodoandrosta-5,16-dien-3β-ol or analogs thereof with tributylstannyl diazines. The compounds are potent inhibitors of human CYP17 enzyme as well as potent antagonists of both wild type and mutant androgen receptors (AR). The compounds are useful for the treatment of human prostate cancer.
摘要:
Studies of the pathogenic mechanisms underlying human myopathies and muscular dystrophies often require animal models, but models of some human diseases are not yet available. The present invention provides methods to promote the engraftment and development of myogenic cells from individuals with such diseases into mature muscle tissue in mice to treat muscle diseases, muscle injury and reduced muscle function. Immortalized human myogenic precursor cells (hMPCs) form mature human myofibers following implantation into the hindlimbs of immunodeficient mice. The engraftment of the cells and their development into mature muscle myofibers is promoted by intermittent neuromuscular electrical stimulation (iNMES) of the peroneal nerve of the engrafted limb. The human myofibers that form are innervated, their contractile apparatus is fully differentiated, and they are comprised of human myonuclei, with minimal contamination by murine myonuclei.
摘要:
Techniques for enhanced fluorescence include a Tamm substrate for a target optical frequency comprising a metal nanoscale layer deposited on a Bragg grating. The Bragg grating includes multiple dielectric layers including multiple high index of refraction layers alternating with multiple low index of refraction layers. The dielectric layers are parallel to the metal nanoscale layer; and, the thickness of each dielectric layer is about a fourth of a wavelength of the target optical frequency in the layer. The metal nanoscale layer is configured to host a fluorophore such that an S polarized emission from the fluorophore at the target optical frequency propagates out of the substrate perpendicular to the plurality of dielectric layers.
