Polyploidy is a key factor in the evolution of higher plants and plays an important role in the variation of plant genomes, leading to speciation in some cases. During polyploidisation, different balancing processes take place at the genomic level that can promote variation in nuclear DNA content. We estimated genome size using flow cytometry in 84(More)
BACKGROUND In patients with treated celiac disease (CD), the ingestion of gluten traces contained in gluten-free (GF) wheat substitutes (eg, GF bread, flour, and pasta) could cause persisting intestinal mucosal damage. OBJECTIVE The objective was to evaluate the proportion of CD patients at risk of mucosal damage due to the consumption of GF products in 4(More)
Nuclear DNA amount has been assessed in 21 populations of 19 species of the genus Cheirolophus, and phylogenetic analyses have been performed in order to find the relationships between the species of the Mediterranean Basin and those of Macaronesia. A combined analysis of nuclear ribosomal DNA ITS and ETS has been performed based on Bayesian inference, and(More)
The accuracy and precision of the estimates of hydrodynamic parameters of globular proteins obtained by inverse regression from gel filtration chromatographic data are discussed. The usefulness of gel filtration chromatography as the basis for a rapid and reliable method for the determination of the Stokes radius and the molecular mass is considered. The(More)
Genome size was assessed by flow cytometry in 33 species belonging to seven genera of the tribe Cardueae (Asteraceae), which can be grouped in three taxonomic complexes. 2C nuclear DNA content ranged from 1.49 to 16.98 pg, which is more than elevenfold variation. Genome size correlated well with some karyological traits. Nuclear DNA amount variations also(More)
We examine the determinants of institutional investors when deciding on international capital allocation in Venture Capital and Private Equity Limited Partnerships; this is done through a questionnaire addressed to (potential) Limited Partners world-wide. The respondents provide information about their criteria for international asset allocation. The(More)
This paper presents the statistical analysis of the results of an inter-laboratory study for the luminescent bacteria toxicity bioassay. It also contains a discussion on the statistical methods for the presentation and refinement of the evaluation of the precision of an assay method (including intra- and inter-laboratory variability), with special emphasis(More)
Drawing on theories of generalized exchange and the norm of indirect reciprocity, we conceptualize subordinates’ organizational citizenship behavior directed towards the organization (OCBO) and directed towards peers (OCBI) as antecedents of managerial trustworthy behavior, and examine how managers’ affective trust in subordinates mediates this(More)

The aim of this review is to give a general contemporary overview of the physiologic effects of phytosterols and their role in cholesterol uptake in the intestinal tract. The mechanism of phytosterols action is based on its ability to reduce cholesterol absorption. Doses of 0.8 to 4.0 g/d of phytosterols were used to reduce low-density lipoprotein(More)
