Application of single-drop microextraction coupled with gas chromatography for the determination of multiclass pesticides in vegetables with nitrogen phosphorus and electron capture detection
(2009)In the present work the single-drop microextraction (SDME) technique coupled with GC-NPD and GC-ECD was evaluated for the determination of multi-class pesticides in vegetables. The donor sample solution preparation was ... -
Bayesian validation of a serum and milk ELISA for antibodies against Mycobacterium avium subspecies paratuberculosis in Greek dairy goats across lactation
(2014)We validated a commercial (Idexx Pourquier, Montpellier, France) serum and milk indirect ELISA that detects antibodies against Mycobacterium avium ssp. paratuberculosis (MAP) in Greek dairy goats. Each goat was sampled 4 ... -
The Byzantine wall paintings from the protaton church on Mount Athos, Greece: tradition and science
(2007)The present work is a study of the wall painting complex in the Protaton Church (1295) on Mount Athos, Greece. These paintings, high in artistic value, are themselves a monument-representative of the Macedonian iconographic ... -
Chemometric study and optimization of extraction parameters in single-drop microextraction for the determination of multiclass pesticide residues in grapes and apples by gas chromatography mass spectrometry
(2009)A simple and rapid single-drop microextraction method coupled with gas chromatography and mass spectrometry (SDME-GC/MS) for the determination of 20 pesticides with different physicochemical properties in grapes and apples ... -
Current clinical, laboratory, and treatment outcome characteristics of visceral leishmaniasis: results from a seven-year retrospective study in Greece
(2015)Objectives: Visceral leishmaniasis (VL) is re-emerging in endemic areas. The epidemiological, clinical, laboratory, and treatment outcome characteristics in a large cohort of VL patients is described herein. Methods: The ... -
DETECTION AND GENETIC CHARACTERIZATION OF PORCINE CIRCOVIRUS 2 ISOLATES FROM THE FIRST CASES OF POSTWEANING MULTISYSTEMIC AND WASTING SYNDROME IN WILD BOARS IN GREECE
(2008)In 2002, postweaning multisystemic wasting syndrome (PMWS) was diagnosed in a European female wild boar (Sus scrofa), based on the detection of porcine circovirus 2 (PCV2) DNA in various organs, including the uterus, and ... -
Effects of aflatoxin B1 administration on Greek indigenous goats' milk
(2012)Aflatoxins are toxic metabolites of the fungi Aspergillus spp. After aflatoxin B1 (AFB1) is consumed by lactating animals, it is metabolized to aflatoxin M1 (AFM1), which is excreted into the milk. The present study ... -
Evaluation of a serum-based PCR assay for the diagnosis of canine monocytic ehrlichiosis
(2009)The aim of this study was to estimate the relative diagnostic sensitivity and specificity of a polymerase chain reaction (PCR) assay in the serum of dogs with naturally occurring non-myelosuppressive canine monocytic ... -
From Byzantine to post-Byzantine art: the painting technique of St Stephen's wall paintings at Meteora, Greece
(2008)The old katholikon of St Stephen's monastery at the Meteora (site of the most important complex of monasteries in Greece after Mount Athos) is decorated with wall paintings that date from the beginning of 17th century. In ... -
Headspace single-drop microextraction of common pesticide contaminants in honey-method development and comparison with other extraction methods
(2012)In the present study the main factors that may influence the headspace single-drop microextraction (HS-SDME) of common pesticide contaminants (diazinon, lindane, chlorpyrifos ethyl, p,p'-DDE, and endosulfan) that may occur ... -
High sequence divergence in the 5 ' non-coding region of reference Coxsackie B and ECHO viral strains and clinical isolates revealed by restriction fragment length polymorphism analysis
(2001)We report the restriction fragment length polymorphism (RFLP) patterns of a 440-bp-long 5' non-coding region (5'NCR) amplification target of all 34 reference Coxsackie B and ECHO (enteric cytopathic human orphan) enterovirus ... -
A large waterborne gastroenteritis outbreak in central Greece, March 2012: challenges for the investigation and management
(2014)In March 2012, there was an unusual increase of gastroenteritis cases in a district with 37264 inhabitants in central Greece. It was estimated that more than 3600 people developed symptoms. A 1:1 case-control study showed ... -
Level of Streptococcus pyogenes in patients with recurrent tonsillitis and tonsillar hypertrophy
(2008)Recurrent tonsillitis is 1 of the common human infectious diseases worldwide, but, to date, its pathogenesis remains unclear. Although Streptococcus pyogenes (GAS) is involved in recurrent bouts of acute tonsillitis, ... -
