(2017)AIM: To investigate the impact of inflammatory bowel disease (IBD) on α2-Heremans-Schmid Glycoprotein (AHSG/fetuin A) and potential associations with disease and patient characteristics. METHODS: AHSG serum levels were ... -
Anti-MCV antibodies predict radiographic progression in Greek patients with very early (<3 months duration) rheumatoid arthritis
(2017)This study aimed to assess the diagnostic and prognostic value of anti-mutated citrullinated vimentin (MCV) antibodies in very early rheumatoid arthritis (VERA) and in established rheumatoid arthritis (RA). Seventy-one ... -
Application of Bayesian modeling for diagnostic assays of Mycobacterium avium subsp. paratuberculosis in sheep and goats flocks
(2022)Background: This study aimed to screen the sera of goats and sheep from flocks suspected of Mycobacterium avium subsp. paratuberculosis (MAP) infection by a newly standardized Mce-truncated ELISA (Mt-ELISA) kit for the ... -
Bayesian estimation of sensitivity and specificity of a commercial serum/milk ELISA against the Mycobacterium avium subsp. Paratuberculosis (MAP) antibody response for each lactation stage in Greek dairy sheep
(2016)A total of 854 paired milk and blood samples were collected from ewes of a Greek flock and used to estimate the sensitivity and specificity of a commercial ELISA for detection of Mycobacterium avium subsp. paratuberculosis ... -
Bayesian estimation of sensitivity and specificity of a PCR method to detect Coxiella burnetii in milk and vaginal secretions in sheep and goat samples
(2019)Coxiella burnetii is a gram-negative and polymorphic rod bacterium that causes Q fever, a common zoonotic disease distributed worldwide. Widespread occurrences of the disease outbreaks indicate the importance of coordinated ... -
Bayesian latent class analysis when the reference test is imperfect [Analyse bayésienne à classes latentes dans les situations où le test de référence est imparfait] [Análisis bayesiano de clases latentes cuando la prueba de referencia es imperfecta]
(2021)Latent class analysis (LCA) has allowed epidemiologists to overcome the practical constraints faced by traditional diagnostic test evaluation methods, which require both a gold standard diagnostic test and ample numbers ... -

A capillary zone electrophoresis method for determining N-acetylneuraminic acid in glycoproteins and blood sera
(2002)A simple capillary zone electrophoresis (CZE) method for the determination of the content of the major sialic acid form N-acetylneuraminic acid (Neu5Ac) in glycoproteins was established. The present method utilizes a ... -
A colorimetric IsoPCR for the rapid and sensitive visual detection of high-risk HPV16 in clinical samples with hydroxynaphthol blue
(2021)HPV16 infection is found in more than 50 % of cervical cancer cases worldwide, triggering the development of numerous molecular techniques for viral diagnosis. The present study focuses on the development of a colorimetric ... -
COMP serum levels: A new non-invasive biomarker of liver fibrosis in patients with chronic viral hepatitis
(2017)Background & aims Recently we have shown that cartilage oligomeric matrix protein (COMP), a fibrillar collagen assembly regulator, is strongly associated with cirrhosis and hepatocellular carcinoma progression. Therefore, ... -
Computer-aided clinical image analysis for non-invasive assessment of tumor thickness in cutaneous melanoma
(2021)Objective: Computerized clinical image analysis is shown to improve diagnostic accuracy for cutaneous melanoma but its effectiveness in preoperative assessment of melanoma thickness has not been studied. The aim of this ... -
Construction of joint confidence regions for the optimal true class fractions of Receiver Operating Characteristic (ROC) surfaces and manifolds
(2017)The three-class approach is used for progressive disorders when clinicians and researchers want to diagnose or classify subjects as members of one of three ordered categories based on a continuous diagnostic marker. The ... -
Development and performance characteristics evaluation of a new Bioelectric Recognition Assay (BERA) method for rapid Sars-CoV-2 detection in clinical samples
(2021)Introduction: As the second wave of COVID-19 pandemic is in progress the development of fast and cost-effective approaches for diagnosis is essential. The aim of the present study was to develop and evaluate the performance ... -
