  • Patent number: 7183070
    Abstract: The present invention is based on the findings that BACE2, a homolog of ?-secretase BACE, is able to stimulate processing of APP in a non-amyloidogenic pathway, thereby suppressing the level of A?. Accordingly, the present invention provides methods and means for the identification and use of modulators of this unique activity of BACE2 to suppress A? production. The compounds identified using the methods and means provided herein may be used as potential candidates for the treatment of Alzheimer's disease and other neurological diseases by reducing ?-amyloid deposit formation.

  • Publication number: 20070023132
    Abstract: A method for forming a tubular member includes preparing a longitudinal Teflon strap, winding the Teflon strap around a longitudinal core to form a tubular prototype having two or more layers, and welding the two or more layers of the Teflon strap together to form the tubular member. The layers of the Teflon strap are preferably arranged at different angles or inclined relative to each other, or arranged at different angles with respect to the longitudinal axis of the core or of the elongate tubular member. The tubular member may further be shaped to various shapes or configurations with such as extending, stretching, expanding, enlarging, or shaping process.

  • Patent number: 7117236
    Abstract: The present invention provides a device and method for applying 1-D and 2-D DCT and IDCT transforms to sets of input data, typically 8×8 or 16×16 matricies of coefficients. In one embodiment, the present invention provides input lines, logic to pre-add input values and generate operands and one or more adder networks that effectively carry out the multiplication operations required to apply a DCT/IDCT transform. The device may apply a 1-D transform twice to accomplish a 2-D transform. Alternatively, the present invention may either include successive stages of logic for the second 1-D transform or it may send data transformed once back through the same logic to pre-add and adder networks for the second 1-D transform. Calculations may be carried out after Booth encoding of operands. The processing may be split between producing vp, a vector of sums of output values, and producing vn, a vector of differences of output values, which vectors may be recombined to produce an output vector v.

  • Publication number: 20060183160
    Abstract: The invention concerns a novel ?-secretase, a method of partially purifying this novel ?-secretase, and its use in assays to screen for potential drug candidates against Alzheimer's disease and other neurological diseases. The novel ?-secretase has an estimated molecular weight of about 32-39 kDa or 22-26 kDa in HEK293 cell membrane extracts and human brain samples, respectively, as calculated from radiation inactivation analysis, and has a pH optimum at about pH 6.5-7.0.

  • Patent number: 6871208
    Abstract: A device and method are described that apply 1-D and 2-D discrete cosine transforms (DCT) and inverse discrete cosine transforms (IDCT) to sets of input data, typically 8×8 or 16×16 matricies of coefficients. One device includes input lines, logic to pre-add input values and generate opcrands and one or more adder networks that effectively carry out the multiplication operations required to apply a DCT/IDCT transform. The device may apply a 1-D transform twice to accomplish a 2-D transform. Alternatively, the device may either include successive stages of logic for the second 1-D transform or it may send data transformed once back through the same logic or pre-add and adder networks for the second 1-D transform. Calculations may be carried out after Booth encoding of operands. The processing may be split between producing vp, a vector of sums of output values, and producing vn, a vector of differences of output values, which vectors may be recombined to produce an output vector v.
