In this paper, we report our experience in the development of a system for automatic acquisition of Immuno-Fluorescence Assay (IFA) images. We focus on two basic issues. Firstly, we determine an autofocus function that can deal with photobleaching, a physical phenomenon affecting automatic acquisition of IFA images, and present a set of experiments on real(More)
INTRODUCTION In recent years, there has been an increased demand for computer-aided diagnosis (CAD) tools to support clinicians in the field of indirect immunofluorescence. To this aim, academic and industrial research is focusing on detecting antinuclear, anti-neutrophil, and anti-double-stranded (anti-dsDNA) antibodies. Within this framework, we present a(More)

BACKGROUND To compare tumor necrosis in hepatoma induced in rats by a single percutaneous injection of ethanol (PEI) or acetic acid (PAI). METHODS BW7756 hepatomas of 1 mm3 were implanted in the liver of 40 male healthy rats. After 14 days, the 36 surviving rats were treated, in a single session, by ultrasound-guided injection of 300 microl of 95% ethanol(More)
INTRODUCTION The objective of the present study was to compare QUANTA Flash dsDNA, a chemiluminescent immunoassay (CIA) on the BIO-FLASH, a rapid-response chemiluminescent analyzer, to three other anti-dsDNA antibody assays and to Crithidia luciliae indirect immunofluorescence test (CLIFT). METHODS In the first part of the study, 161 samples, 61 from(More)
Whether tumor necrosis factor-alpha (TNFα) caused beneficial or detrimental cardiovascular effects remains poorly defined. Anti-TNFα agents improved cardiac end points in chronic rheumatic diseases characterized by progressive deterioration of cardiac function. In contrast, anti-TNFα agents did not always improve but actually worsened cardiac function in(More)
Deaths after percutaneous ethanol injection (PEI) into hepatocellular carcinoma (HCC) may occur within a few hours to a few days following the procedure because of hemoperitoneum and haemorrhage from oesophageal varices or hepatic insufficiency. Pancreatitis has been recently reported as a rare lethal complication of intra-arterial PEI, another modality for(More)
