Abstract: This invention provides a method for modulating the expression of a first gene in a cell wherein the first gene is one containing more than 36 CAG trinucleotide repeats and encoding a protein that form polyglutamine-mediated protein aggregation. Suppression of the first gene is achieved by reducing the expression of SPT4 gene or SUPT4H gene. It can also be achieved by inhibiting the formation of a Spt4/Spt5 complex or a Supt4h/Supt5h complex. Also provided is a method for identifying an agent useful for modulating the expression and aggregation of CAG-expanded gene product, or treating a polyglutamine disease such as Huntington's disease.

Abstract: The present invention relates to a method for detecting cancer initiating cells in living animal body by multimodality reporter gene imaging. In the method of this invention, cells escaping from cell loss during tumor enlargement are identified as cancer initiating cells.
Abstract: Present invention relates to an ultrasonically-triggered drug vehicle with magnetic resonance imaging function. In the delivery system of the invention, tracks the of drug vehicle carrying a certain drug (or drugs) is detectable by magnetic resonance imaging, and the release of drug is triggered by ultrasonication when the drug vehicle arrives at target site and accumulates to a desirable concentration. The MRI-guided drug delivery system provides improved accuracy of drug releasing, including position and timing.
Abstract: The present invention provides new compounds of formula I, II or III, which have Src homology-2 containing protein tyrosine phosphatase-1 (SHP-1) agonist activity. Also provided are treatment methods using the compounds of formula I, II or III.

Abstract: Aspects of the invention include methods of selectively reducing the deleterious activity of mutant extended trinucleotide repeat containing genes in a cell, as well as compositions used in such methods. The deleterious activity (e.g., toxicity and/or dis-functionality of products encoded thereby) of a mutant extended trinucleotide repeat containing gene may be selectively reduced in a variety of different ways, e.g., by selectively decreasing SPT4 mediated transcriptional activity, by enhancing functionality of proteins encoded thereby, etc. Aspects of the invention further include assays for identifying agents that find use in methods of the invention, e.g. as summarized above. Methods and compositions of the invention find use in a variety of different applications, including the prevention or treatment of disease conditions associated with the presence of genes containing mutant extended trinucleotide repeats, such as Huntington's Disease (HD).

Abstract: The present invention discloses a computed tomography (CT) image reconstruction method using two-dimensional images at different angles as well as a two-dimensional virtual matrix on a basis of spherical space, to process projection, comparison, and correction. Thus, it can obtain the tomography within predetermined difference value to reduce computational and storage space. Matching the parameters of energy source and image capturing can further shorten energy radiation on an object's (i.e. a human body) exposure time, in order to reduce radiation effects of energy sources (i.e. as X-rays) of the object (i.e. as a human body).
