  • Publication number: 20120214186
    Abstract: The present invention provides methods (assays) for detecting and/or quantifying sAPP?, a secreted ?-secretase (BACE1) cleavage fragment of the ?-amyloid precursor protein (APP), in a biological sample. One such method includes contacting a biological sample with a first antibody that selectively binds to a BACE1 cleavage site on sAPP? and detecting the presence of the antibody. Also provided are compositions, including antibodies that selectively bind to the BACE1 cleavage site of sAPP?. Kits containing such compositions are also provided. Methods of diagnosing a neurodegenerative disease, such as AD, using the methods and compositions of the present invention are further provided. Methods for identifying BACE1 modulators, candidate compounds that are BACE1 modulators, and methods for treating, preventing or ameliorating neurodegenerative disease, such as AD, using such compounds or pharmaceutical compositions containing such compounds are also provided.

  • Publication number: 20120213419
    Abstract: A pattern recognition method using Maximization of Mutual Information (MMI)-based Local Binary Pattern (LBP) codes transforms training face images into LBPs and generates LBP-transformed feature vectors based on positions of image pixels. Thereafter, a dimension of each image is reduced by selecting feature vectors maximizing mutual information with a class label vector from among N feature vectors, 256 LBP frequency feature vectors are obtained by performing an LBP code-based histogram transform per image, and Optimal LBP (OLBP) codes maximizing mutual information with the class label vector for the 256 LBP frequency feature vectors are selected. These selected OLBP codes are codes guaranteeing minimization of a classification error rate, and by applying the selected OLBP codes to pattern recognition, a better recognition performance than a conventional local kernel-based image representation method and an enhanced recognition speed due to a reduced number of LBP codes are provided.

  • Publication number: 20110177569
    Abstract: Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E. coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E. coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.
