Abstract:
The present invention relates to method(s) of treating a subject afflicted with cancer or a precancerous condition, an inflammatory disease or condition, and/or stroke or other ischemic disease or condition, the method comprising administering to the subject or patient in need a composition comprising a therapeutically effective amount of a substituted cis or trans-stilbene. A method of treating or reducing the likelihood of Alzheimer's disease in a patient is an additional embodiment of the present invention.
Abstract:
Exemplary embodiments provide semiconductor devices including high-quality (i.e., defect free) group III-N nanowires and uniform group III-N nanowire arrays as well as their scalable processes for manufacturing, where the position, orientation, cross-sectional features, length and the crystallinity of each nanowire can be precisely controlled. A pulsed growth mode can be used to fabricate the disclosed group III-N nanowires and/or nanowire arrays providing a uniform length of about 10 nm to about 1000 microns with constant cross-sectional features including an exemplary diameter of about 10-1000 nm. In addition, high-quality GaN substrate structures can be formed by coalescing the plurality of GaN nanowires and/or nanowire arrays to facilitate the fabrication of visible LEDs and lasers. Furthermore, core-shell nanowire/MQW active structures can be formed by a core-shell growth on the nonpolar sidewalls of each nanowire.
Abstract:
Systems, apparatus, and associated methods of forming the systems and/or apparatus may include imaging devices that may comprise multiple arrays of ultrasonic transducer elements for use in a variety of applications. These multiple arrays of ultrasonic transducer elements can be arranged to form a three-dimensional imaging device. Non-coplanar arrays of ultrasonic transducer elements can be coupled together. These imaging devices may be used as medical imaging devices. Additional apparatus, systems, and methods are disclosed.
Abstract:
A surface grafted conjugated polyelectrolyte (CPE) is formed by coupling a CPE by a coupling moiety to the surface of a substrate. The substrate can be of any shape and size, and for many uses of the surface grafted CPE, it is advantageous that the substrate is a nanoparticle or microparticle. Surface grafted CPEs are presented that use silica particles as the substrate, where a modified silane coupling agent connects the surface to the CPE by a series of covalent bonds. Two methods of preparing the surface grafted CPEs are presented. One method involves the inclusion of the surface being modified by the coupling agent and condensed with monomers that form the CPE in a grafted state to the substrate. A second method involves the formation of a CPE with terminal groups that are complimentary to functionality that has been placed on the surface of the substrate by reaction with a coupling agent. The surface grafted CPEs are also described for use as biosensors and biocides.
Abstract:
A biological detector includes a conduit for receiving a fluid containing one or more magnetic nanoparticle-labeled, biological objects to be detected and one or more permanent magnets or electromagnet for establishing a low magnetic field in which the conduit is disposed. A microcoil is disposed proximate the conduit for energization at a frequency that permits detection by NMR spectroscopy of whether the one or more magnetically-labeled biological objects is/are present in the fluid.
Abstract:
A Scanning Phase Intracavity Nanoscope as a measurement system can be realized with a reference laser cavity and a sample laser cavity superimposed upon each other to operatively propagate two laser beams. The sample laser cavity is operatively formed by the sample to be measured. A measurement of the sample is based on differences in the reference laser cavity and the sample laser cavity determined from difference in the two laser beams.
Abstract:
The present invention relates to the use of isotopically labeled derivatives of isoniazid, ethionamide and related compounds as effective therapy for the treatment of mycobacterial diseases, including Mycobacterium tuberculosis.
Abstract:
A method of calculating radiation fluence and energy deposition distributions on a networked virtual computational cluster is presented. With this method, complex Monte Carlo simulations that require expansive equipment, personnel, and financial resources can be done efficiently and inexpensively by hospitals and clinics requiring radiation therapy dose calculations.
Abstract:
Methods and instruments for high dynamic range analysis of sample components are described. A sample is subjected to time-dependent separation, ionized, and the ions dispersed with a constant integration time across an array of detectors according to the ions m/z values. Each of the detectors in the array has a dynamically adjustable gain or a logarithmic response function, producing an instrument capable of detecting a ratio of responses or 4 or more orders of magnitude.
Abstract:
The invention enables the display of antibody single-chain variable fragments (scFv's on virus-like particles (VLPs) of bacteriophages such as MS2. The VLPs encapsidate mRNA encoding the coat protein from which it assembles, enabling the recovery by reverse transcription and PGR of affinity-selected sequences from scFv libraries. Related virus-like particles, method for constructing a library of scFv-VLPs, drug delivery vehicles comprising one or more pharmaceutically-active ingredients, biomedical imaging agents, assays, and kits are also provided.
