BACKGROUND: The anti-nuclear antibody immunofluorescence (ANA-IF) test is used for screening of autoantibody presence in patients with suspected autoimmune disease. Positive ANA-IF should be followed-up extractable nuclear antigens profile (ENA-profile). High sensitivity combined low ENA-profile sensitivity, and the evolution requests may result a higher number positive but negative ENA-profile...

Abstract Digital Image Correlation technique (DIC) is a non-contact optical method for rapid structural health monitoring of critical infrastructure. DIC used to extract Moment (M) – Curvature (κ) relationships using random speckle patterns. The pattern evaluated 2D measurements and shows an improved correlation with conventional measurements. Characteristics patterns are quantified their appli...

This paper turns on ultrasound image despeckling by using Multiplicative Multiresolution Decomposition MMD. The proposed method is based on MMD’s coefficient thresholding. The used thresholds are automatically evaluated from the transformed image content. Tests are conducted on simulated speckled and real ultrasound images. Obtained results show that the proposed method outperforms the consider...

Images obtained with coherent illumination, as is the case of sonar, ultrasound-B, laser and Synthetic Aperture Radar – SAR, are affected by speckle noise which reduces the ability to extract information from the data. Specialized techniques are required to deal with such imagery, which has been modeled by the G0 distribution and under which regions with different degrees of roughness and mean ...

OBJECTIVE Several antibodies have proven to be useful in autoimmune diseases, as markers for diagnosis, prognosis or clinical manifestations. Our objective was to evaluate the diagnosis and manifestations associated for antibodies anti-Ro52, anti-Ro60 and anti-La at a referral hospital in Spain. METHODS We retrospectively analyzed the antigenic specificities of the consecutive samples submitt...

Objective: Aim of this study is to evaluate anti-nuclear antibody (ANA) test results obtained between 2009 and 2011. Methods: Of a totally 5068 cases tested for ANA by indirect immunofluorescence method (IIFA), randomly chosen 982 ANA-positive cases were reviewed in terms of gender, level and pattern of fluorescence, anti-dsDNA (anti-double stranded DNA) and anti-extractable nuclear antigen (EN...
