Abstract: The present invention refers to human antibodies derived from human antibody libraries prepared from atherosclerotic plaques. It further refers to human antibodies able to immunologically recognize both human transgelin or fragments thereof and a protein with at least 50% similarity to OmpK36 (Outer membrane protein, Klebsiella, K36; GI: 295881594) or fragments thereof. Human transgelin is preferably transgelin 1 (Accession N° Q01995, GI:48255907). The antibodies further recognize an antigen in the atherosclerotic plaque and are useful for the preparation of immunodiagnostic reagents or assays to detect atherogenic diseases. The invention also relates to the use of anti-TAGLN monoclonal antibodies, showing cross-reactivity with a bacterial antigen having at least 50% similarity with OmpK36, for detecting antigens in the atherosclerotic plaque or as atherosclerotic related reagents in an immuno-competition assay.

Abstract: A method for coding pixels or voxels of a digital or digitalized two dimensional or three dimensional image includes the steps of: providing a digital image in which each pixel or voxel is defined by a variable in a grey scale image, or by HSV or RGB values in a color image; generating a vector univocally associated to the target pixel or voxel and having components generated as a function of the values of the pixels or voxels in a window that includes the target pixel or voxel and neighboring pixels or voxels. The function of the values of the target pixel or voxel and of the pixels or voxels in the window corresponds to the characteristic parameters of the numerical matrix representing the pixels or voxels of the window or of a transformation of the numerical matrix.
