This paper describes the results after using an automatic classification method to help improve the retrieval of medical images. Using a large dataset of medical images, we established links between low-level features from medical images and high-level features from textual codes of Image Retrieval for Medical Application (IRMA). This paper also explains the process and methods used to automati...

Although the hepatitis C virus (HCV) infection is one of the major causes of chronic hepatitis and hepatocellular carcinoma (HCC) in Mongolia, its prevalence among children and routes of transmission are largely unknown. The aim of the study was to determine the prevalence of anti-HCV antibodies and the possible risk factors for transmission among school children using representative national d...

Background: Studies have demonstrated that sickle cell trait can be found in an asymptomatic healthy carrier with normal complete blood count (CBC) and red blood cell (RBC) indices. According to Iranian Ministry of Health bulletin instructions, prenuptial Thalassemia Screening Program (TSP) primarily depends on RBC indices which are measured through a routine CBC. Only when these levels are bel...

We report the development and characterization of an IRMA for the direct measurement of nicked human chorionic gonadotropin (hCGn) in blood and urine. hCGn derived from a reference preparation of hCG used as an immunogen elicits monoclonal antibodies (mAbs) with enhanced recognition of human luteinizing hormone epitopes. The most specific assay for pregnancy hCGn is an IRMA composed of one mAb ...

Do Commercially Available Assay Kits for B-Type Natriuretic Peptide Measure Pro-BNP1-108, as Well as BNP1-32? To the Editor: We read with great interest the recent article by Heublein et al1 on plasma pro-BNP1-108 measurement with commercially available assay kits and the effect of pro-BNP1-108 on cGMP levels. They demonstrated that Shionogi’s or Biosite’s triage assay kit did not cross-react w...

Using human liver ferritin as a model, we have developed a two-site immunoradiometric assay. Sample (or standard) is incubated with excess rabbit antiserum and 125I-labeled specific sheep antibodies directed against different antigenic determinants until equilibrium is reached. Then excess sheep anti-rabbit immunoglobulin G serum, covalently linked to magnetizable particles, is added. The radio...
