ACCase mutations in Avena sterilis populations and their impact on plant fitness.

Avena sterilis (sterile oat) populations originating from wheat-growing regions of Greece, developed resistance to fenoxaprop, clodinafop and other herbicides. The partial ACCase gene sequence revealed six point mutations (Ile-1781-Leu, Trp-1999-Cys, Trp-2027-Cys, Ile-2041-Asn, Asp-2078-Gly, and Cys-2088-Arg) in 24 out of the 26 resistant (R) populations, confirming the molecular mechanism of resistance to ACCase-inhibiting herbicides. However, DNA sequence of two R populations did not reveal any known ACCase mutations, suggesting possible presence of unknown mutation or metabolism-based mechanism of resistance.

Nursing students' attitudes toward statistics: Effect of a biostatistics course and association with examination performance.

Background: Although statistical knowledge and skills are necessary for promoting evidence-based practice, health sciences students have expressed anxiety about statistics courses, which may hinder their learning of statistical concepts.

Objectives: To evaluate the effects of a biostatistics course on nursing students' attitudes toward statistics and to explore the association between these attitudes and their performance in the course examination.

Design: One-group quasi-experimental pre-test/post-test design.

Sex-specific daily spawning seaward migration of striped mullet Mugil cephalus in a coastal lagoon.

The sex-specific daily spawning seaward migration of striped mullet Mugil cephalus was analysed in Palaiopotamos Lagoon (western Greek coast, eastern Mediterranean Sea) in an 86 day time series. The data set included the daily number of M. cephalus catches in barrier traps, as well as a time series of some weather variables.

Oxidovanadium(IV/V) complexes as new redox mediators in dye-sensitized solar cells: a combined experimental and theoretical study.

Corrosiveness is one of the main drawbacks of using the iodide/triiodide redox couple in dye-sensitized solar cells (DSSCs). Alternative redox couples including transition metal complexes have been investigated where surprisingly high efficiencies for the conversion of solar to electrical energy have been achieved. In this paper, we examined the development of a DSSC using an electrolyte based on square pyramidal oxidovanadium(IV/V) complexes.

Introducing dAUTObase: a first step towards the global scale geoepidemiology of autoimmune syndromes and diseases.

Motivation: An autoimmune disorder occurs when the immune system mistakenly attacks and destroys its own healthy body tissues. The initiation of a geoepidemiological database, for recording autoimmune incidents with a focus to clinical manifestations, demographic parameters and geographic background is crucial to detect correlations.

Results: The dAUTObase collects an ever increasing number of publications-currently counting 435-on autoimmune diseases' frequencies in various populations and ethnic groups.

Complex statistics and diffusion in nonlinear disordered particle chains.

We investigate dynamically and statistically diffusive motion in a Klein-Gordon particle chain in the presence of disorder. In particular, we examine a low energy (subdiffusive) and a higher energy (self-trapping) case and verify that subdiffusive spreading is always observed. We then carry out a statistical analysis of the motion, in both cases, in the sense of the Central Limit Theorem and present evidence of different chaos behaviors, for various groups of particles.

Predictors of nurses' knowledge and attitudes toward postoperative pain in Greece.

Undertreatment of postoperative pain can aggravate patient outcomes and is associated with attending nurses' knowledge deficits or negative attitudes toward pain. The aim of this study was to investigate knowledge and attitudes toward postoperative pain of surgical department nurses and to identify predictors of their knowledge and attitudes. This was a descriptive, cross-sectional survey that took place in the departments of general surgery, orthopedics, neurosurgery, ear-nose-throat surgery, and obstetrics/gynecology at five Greek hospitals.

Nursing personnel's attitudes towards fever and antipyresis of adult patients: cross-sectional survey.

Aims And Objectives: To investigate the attitudes of nurses caring for hospitalised adult patients towards fever and antipyresis and to identify the predictors of these attitudes.

Background: Fever is a host defence mechanism, whose harmful effects are limited to specific patients. Findings about antipyretic treatment have further challenged the need for routine or aggressive fever suppression.

Residual neuromuscular blockade and postoperative critical respiratory events: literature review.

Aims And Objectives: To investigate and synthesise published literature on the associations between residual neuromuscular blockade and critical respiratory events of postoperative adult patients in the postanaesthesia care unit.

Background: Residual neuromuscular blockade continues to be common among patients transferred to the postanaesthesia care unit after general anaesthesia, while negative effects of residual neuromuscular blockade on respiratory function have been demonstrated in laboratory volunteers.

Design: Literature review.

Developments in FINDbase worldwide database for clinically relevant genomic variation allele frequencies.

FINDbase (http://www.findbase.org) aims to document frequencies of clinically relevant genomic variations, namely causative mutations and pharmacogenomic markers, worldwide.
