Cost of reproduction in male medflies: The primacy of sexual courting in extreme longevity reduction
(2010)In polygynous insect species, male reproductive success is directly related to lifetime mating success. However, the costs for males of sexual activities such as courting, signaling, and mating are largely unknown. We ... -
Detection of mutations in the FemXAB protein family in oxacillin-susceptible mecA-positive Staphylococcus aureus clinical isolates
(2010)Methicillin-resistant Staphylococcus aureus (MRSA) strains that express the mecA gene but are oxacillin susceptible (OS-MRSA; oxacillin MIC < 2 mg/L) are increasingly reported. To gain molecular and functional insights on ... -
Developing the Evidence Base for Cancer Chemoprevention: Use of Meta-Analysis
(2011)Meta-analysis is a quantitative approach for systematically combining the results of previous studies in order to arrive at conclusions about the body of research. It answers a specific research question, includes an ... -
Extreme between-study homogeneity in meta-analyses could offer useful insights
(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: ... -
Genome-wide scans meta-analysis for pulse pressure
(2007)Genome scans for identifying susceptibility loci for pulse pressure have produced inconclusive results. A heterogeneity-based genome search meta-analysis was applied to available genome-scan data on pulse pressure. A genome ... -
Heterogeneity testing in meta-analysis of genome searches
(2005)Genome searches for identifying susceptibility loci for the same complex disease often give inconclusive or inconsistent results. Genome Search Meta-analysis (GSMA) is an established non-parametric method to identify genetic ... -
Identification of chromosomal regions linked to premature myocardial infarction: a meta-analysis of whole-genome searches
(2006)Myocardial infarction (MI) is a complication of coronary artery disease and the leading cause of death in the Western world. MI is considered a distinct phenotype with an increased genetic component for its premature type. ... -
THE IMPACT OF HUMAN LAND USE ON THE COMPOSITION AND RICHNESS OF GROUND AND DUNG BEETLE ASSEMBLAGES
(2014)This paper presents the results of a survey on the habitat and seasonal variation in activity density and richness of ground and dung beetle assemblages in a heterogeneous landscape of central Greece. Beetles were collected ... -
THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(2008)The objective of this work was to experimentally investigate the influence of vent type (side, roof, or both) and of anti-aphid insect screens on airflow, air temperature, and air vapor pressure deficit distribution in a ... -
Meta-analysis for ranked discovery datasets: Theoretical framework and empirical demonstration for microarrays
(2008)The combination of results from different large-scale datasets of multidimensional biological signals (such as gene expression profiling) presents a major challenge. Methodologies are needed that can efficiently combine ... -
Obligate annual and successive facultative diapause establish a bet-hedging strategy of Rhagoletis cerasi (Diptera: Tephritidae) in seasonally unpredictable environments
(2017)To cope with temporal and spatial heterogeneity of habitats, herbivorous insects in the temperate zone usually enter diapause that facilitates synchronization of their life cycle with specific stages of host plants, such ... -
The role of MTHFR gene in multiple myeloma
(2008)Case-control studies investigating associations between multiple myeloma (MM) and the C677T and A1298C polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) have provided controversial results. In an attempt to ... -
Spatial Heterogeneity and Economic Dualism in European Neighbourhood Policy Countries
(2016)This article studies how spatial heterogeneity (by urban concentration) and economic heterogeneity (by economic dualism), which are being affected by trade integration with the EU, influence the growth of European Neighbourhood ... -
Synthesis of genetic association studies for pertinent gene-disease associations requires appropriate methodological and statistical approaches
(2008)Objective: The aim of the study was to consider statistical and methodological issues affecting the results of meta-analysis of genetic association studies for pertinent gene-disease associations. Although the basic ...
