Analysis of olive fly invasion in California based on microsatellite markers

Zygouridis, N. E.; Augustinos, A. A.; Zalom, F. G.; Mathiopoulos, K. D. (2009)

The olive fruit fly, Bactrocera oleae, is the main pest of the olive fruit and its expansion is exclusively restricted to the cultivation zone of the olive tree. Even though olive production has a century-old history in ...

Cerebellar function, dyslexia and articulation speed

Kasselimis, D. S.; Margarity, M.; Vlachos, F. (2008)

The main aims of this study were a) to assess the cerebellar deficit hypothesis examining children's performance in cerebellar and cognitive tasks associated with the dyslexic syndrome and b) to investigate if there is a ...

Clonal spread of KPC-2 carbapenemase-producing Klebsiella pneumoniae strains in Greece

Pournaras, S.; Protonotariou, E.; Voulgari, E.; Kristo, I.; Dimitroulia, E.; Vitti, D.; Tsalidou, M.; Maniatis, A. N.; Tsakris, A.; Sofianou, D. (2009)

KPC-possessing Klebsiella pneumoniae have been found to be widespread in several regions but are still rarely detected in Europe. We describe the characteristics of an outbreak caused by KPC producers in a tertiary care ...

Construction of Confidence Regions in the ROC Space after the Estimation of the Optimal Youden Index-Based Cut-Off Point

Bantis, L. E.; Nakas, C. T.; Reiser, B. (2014)

After establishing the utility of a continuous diagnostic marker investigators will typically address the question of determining a cut-off point which will be used for diagnostic purposes in clinical decision making. The ...

Crime and the effectiveness of public order spending in Greece: Policy implications of some persistent findings

Kollias, C.; Mylonidis, N.; Paleologou, S. M. (2013)

Increasing crime rates invariably result in calls for more police protection which requires the allocation of additional scarce resources to policing and public order. In an environment of fiscal pressures, the effectiveness ...

The effect of government expenditure on the environment: An empirical investigation

Halkos, G. E.; Paizanos, E. A. (2013)

This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000. We estimate both the direct and indirect effects of government spending on pollution. ...

Enhancing specificity in proxy-design for the assessment of bioenergetics

Flouris, A. D.; Koutedakis, Y.; Nevill, A.; Metsios, G. S.; Tsiotra, G.; Parasiris, Y. (2004)

The purpose of this study was to examine the hypothesis that improved prediction of bioenergeties may be achieved when proxies are designed to simulate closely gold standard laboratory protocols. To accomplish this, a ...

Evaluation of a microsphere-based flow cytometric assay for diagnosis of Celiac disease

Yiannaki, E. E.; Zintzaras, E.; Analatos, A.; Theodoridou, C.; Dalekos, G. N.; Germenis, A. E. (2004)

The multiplexed particle-based flow cytometric technology proposes a new approach for the diagnosis of autoimmune diseases combining the advantages of conventional methods with the ability to quantitatively determine ...

Evaluation of a serum-based PCR assay for the diagnosis of canine monocytic ehrlichiosis

Mylonakis, M. E.; Siarkou, V. I.; Leontides, L.; Bourtzi-Hatzopoulou, E.; Kontos, V. I.; Koutinas, A. F. (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 ...

Extreme between-study homogeneity in meta-analyses could offer useful insights

Ioannidis, J. P. A.; Trikalinos, T. A.; Zintzaras, E. (2006)

Objectives: Meta-analyses are routinely evaluated for the presence of large between-study heterogeneity. We examined whether it is also important to probe whether there is extreme between-study homogeneity. Study Design: ...

Forecasting the stationary AR(1) with an almost unit root

Halkos, G. E.; Kevork, I. S. (2006)

Although unit root tests have made a great contribution in time series econometrics, their major disadvantage is the low powers they attain on certain occasions, as for the case of the stationary AR(1), when phi is close ...

Imaging modalities for renal artery stenosis in suspected renovascular hypertension: Prospective intraindividual comparison of color Doppler US, CT angiography, GD-enhanced MR angiography, and digital substraction angiography

Rountas, C.; Vlychou, M.; Vassiou, K.; Liakopoulos, V.; Kapsalaki, E.; Koukoulis, G.; Fezoulidis, I. V.; Stefanidis, I. (2007)

The aim of the study was to evaluate the diagnostic accuracy of Color Doppler US, CT Angiography (CTA), and GD-enhanced MR Angiography (MRA) compared with digital subtraction angiography (DSA) for the detection of renal ...

Impact of Hardy-Weinberg equilibrium deviation on allele-based risk effect of genetic association studies and meta-analysis

Zintzaras, E. (2010)

Deviations from Hardy-Weinberg equilibrium (HWE) in control subjects may bias the estimates of genetic effects in genetic association studies (GAS) and meta-analysis. A large empirical evaluation was carried out to evaluate ...

Inhibitor-based methods for the detection of KPC carbapenemase-producing Enterobacteriaceae in clinical practice by using boronic acid compounds

Pournaras, S.; Poulou, A.; Tsakris, A. (2010)

Enterobacteriaceae clinical strains that produce the class A carbapenem-hydrolysing enzyme KPC (Klebsiella pneumoniae carbapenemase) are increasingly reported worldwide, and are already endemic in North and South America, ...
