Acute non-A, non-B, non-C hepatitis differences and similarities between hepatitis E virus infection and autoimmune hepatitis, with phylogenetic analysis of hepatitis E virus in humans and wild boars
(2022)Background Hepatitis E virus (HEV) infection incidence is increasing in Europe, accounting for the majority of acute hepatitis cases. We investigated the prevalence and clinical characteristics of acute hepatitis E (AHE) ... -
Assessing functional status using the IADL-extended scale: Results from the HELIAD study
(2020)Objectives: Instrumental activities of daily living (IADL) have been operationalized as exhibiting a greater level of complexity than basic ADL. In the same way, incorporating more advanced ADLs may increase the sensitivity ... -
Association of specific HLA phenotypes with left ventricular mass and carotid intima-media thickness in hypertensives
(2001)The aim of this study was to investigate the hypothesis that the expression of certain HLA antigens may constitute a risk marker for cardiovascular hypertrophy in subjects with arterial hypertension. We examined 158 subjects ... -
Body mass index and survival from amyotrophic lateral sclerosis: A meta-analysis
(2018)BackgroundSeveral studies have examined the relationship between body mass index (BMI) and survival from amyotrophic lateral sclerosis (ALS). Many indicate that low BMI at diagnosis or during follow-up may be associated ... -
Climate change effects on drought severity
(2008)This paper evaluates climate change effects on drought severity in the region of Thessaly, Greece. The Standardized Precipitation Index (SPI) has been used for estimation of drought severity. A geographical information ... -
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 ... -
Demographic window to aging in the wild: Constructing life tables and estimating survival functions from marked individuals of unknown age
(2004)We address the problem of establishing a survival schedule for wild populations. A demographic key identity is established, leading to a method whereby age-specific survival and mortality can be deduced from a marked cohort ... -
DHLAS: A web-based information system for statistical genetic analysis of HLA population data
(2007)DHLAS (database HLA system) is a user-friendly, web-based information system for the analysis of human leukocyte antigens (HLA) data from population studies. DHLAS has been developed using JAVA and the R system, it runs ... -

(2016)Differential expression analysis (DEA) is one of the main instruments utilized for revealing molecular mechanisms in pathological and physiological conditions. DIANA-mirExTra v2.0 (http://www.microrna. gr/mirextrav2) ... -
Do alcohol-metabolizing enzyme gene polymorphisms increase the risk of alcoholism and alcoholic liver disease?
(2006)Case-control studies that have investigated the association between alcoholism and alcohol-induced liver damage and the ADH2, ADH3, CYP2E1, and ADLH2 polymorphisms have reported controversial or inconclusive results. Thus, ... -
Early gastrostomy reduces the rate of ventilator-associated pneumonia in stroke or head injury patients
(2005)Presence of a nasogastric tube is a risk factor for the development of ventilator-associated pneumonia (VAP). Alternatively, gastrostomy can be used for administration of enteral feedings. To determine whether early ... -
