Abstract:
The present invention is a method and system for developing a dynamic scheme for Gamma Knife radiosurgery based on the concept of "dose-painting" to take advantage of robotic patient positioning systems on the Gamma Knife C and Perfexion units. The spherical high dose volume created by the Gamma Knife unit will be viewed as a 3D spherical "paintbrush", and treatment planning is reduced to finding the best route of this "paintbrush" to "paint" a 3D tumor volume. Under the dose-painting concept, Gamma Knife radiosurgery becomes dynamic, where the patient is moving continuously under the robotic positioning system.
Abstract:
A therapeutic ultrasound device may include a substrate, at least one high power capacitive micromachined ultrasonic transducer, and at least one imager transducer comprising a capacitive micromachined ultrasonic transducer. The at least one high power capacitive micromachined ultrasonic transducer and the imager transducer may be monolithically integrated on the substrate.
Abstract:
Novel compounds generally referred to herein as cationic oligomeric phenylene ethynylenes (OPEs), methods of synthesizing OPEs and various uses for the OPEs are described. The compounds can be synthesized in both symmetrical (S-OPE) and non- symmetrical (N-OPE) forms. Suitable uses include sensor and biocidal applications. Reusable structures incorporating the OPEs that are able to capture and release biological species of interest are also described.
Abstract:
Ultra-thin hybrid and/or microporous materials and methods for their fabrication are provided. In one embodiment, the exemplary hybrid membranes can be formed including successive surface activation and reaction steps on a porous support that is patterned or non-patterned. The surface activation can be performed using remote plasma exposure to locally activate the exterior surfaces of porous support. Organic/inorganic hybrid precursors such as organometallic silane precursors can be condensed on the locally activated exterior surfaces, whereby ALD reactions can then take place between the condensed hybrid precursors and a reactant. Various embodiments can also include an intermittent replacement of ALD precursors during the membrane formation so as to enhance the hybrid molecular network of the membranes.
Abstract:
The present invention is a system and methods of establishing a Melanocyte Protection Factor (MPF), which indicates the level of protection against DNA damage to a target cell, such as the level of protection a particular sunscreen offers against UVA rays when compared to the unprotected case, i.e., no sunscreen. The present invention determines and records levels of stable melanin radicals (SMR) in a target cell. Light is applied to the target cell forming light-induced melanin radicals (LIR). The levels of SMR and intensity of LIR are measured to determine the amount of incident light reaching the target cell. Since LIR is proportional to the square root of light intensity reaching the target cell, the ratio of light reaching the target cell is defined as the MPF (I).
Abstract:
To improve risk classification and outcome prediction in ALL, gene expression profiles were obtained using oligonucleotide arrays in a retrospective case control study of 220 children with B precursor ALL. Using multiple statistical methods and computational tools, these comprehensive gene expression profiles were reduced to a 26 gene expression classifier that was highly predictive of overall outcome. Each of these 26 genes was shown to provide additional prognositc information relative to established prognositc variables. The 26 genes include signaling, adhesion and growth regulatory proteins (RHoGEF4, FYB, HNK-I sulfotransferase, SMADl, HABP4, PHYH, IFI44L, JAGl, EFN-B2, type 3 inositol-1,4,5 triphosphate receptor, MONDOA, DOKl, CDK8, CD44, CL5/RANTES, galectin SPARC) and novel genes not previously known to play a role in hematopoiesis or leukemogenesis (DREBIN, MIDKINE, and the hypothetical protein LJ20154 or OPALlwhich have been cloned and characterized).
Abstract:
Provided is an animal model system for the study of papillomaviruses, especially anogenital papillomaviruses, especially those causing anogenital and/or head and neck cancers. The Rhesus papillomavirus (especially RhPV1) is a useful model for human papillomaviruses which cause anogenital infections and cancers of the anogenital region and/or the head, neck and respiratory system.
Abstract:
The present invention provides a matrix comprising an array of nanostructures that exhibit a variation (gradient) in physical properties (such as size or pitch) in at least one direction of the plane containing said array. A method for forming an array having a gradient property is also provided. In addition, a separation method is provided comprising the steps of: providing a matrix comprising an array of nanostructures arranged so that the array has the property of a gradient; and conducting at least one biomolecule separation process to separate biomolecules in a composition containing a plurality of biomolecules using the matrix.
