Risk assessment associated to the intake of the emerging Fusarium mycotoxins BEA, ENs and FUS present in infant formula of Spanish origin
2012
Abstract Forty-five samples of Spanish follow-up infant formula with different chemical compositions were analyzed determining the emerging Fusarium mycotoxins beauvericin (BEA), enniatins (ENs) (A, A 1 , B, B 1 ), and fusaproliferin (FUS). The samples were extracted three times with ethyl acetate using an Ultra-turrax homogenizer. Mycotoxins were identified and quantified using a liquid chromatography (LC) coupled to a diode array detector (DAD). Results showed that the percentage of the samples contaminated with ENs and FUS were 46.6 and 20.0% respectively, whereas all analyzed samples were free of BEA. The ENs A and B were detected only in one sample with 149.6 and 39.4 mg/kg respectivel…
Water chemistry and abiogenic methane content of a hyperalkaline spring related to serpentinization in the Argolida ophiolite (Ermioni, Greece)
2018
Abstract Hyperalkaline mineral springs related to active continental serpentinization are a theme of growing interest since they may contain significant amounts of abiotic gas and have important implications for energy resource exploration, subsurface microbiology and astrobiology. We report the discovery of a new hyperalkaline (pH∼12) spring issuing in the Agioi Anargyroi monastery at Ermioni (Greece), connected to serpentinization of peridotites of the Argolis ophiolite. Two water samples have been collected from separated springs and analysed for the chemical composition of major, minor and trace elements, and isotopic composition (2H and 18O) of water by IC, ICP-OES, ICP-MS and IRMS, an…
Diversity in local cultivars of Pisum sativum collected from home gardens in Sweden
2015
Abstract Although one would assume that finding any local cultivars in home gardens in a modern society such as Sweden is unlikely, such cultivars were in fact found. More than 170 seed accessions of vegetables, pulses and other seed-propagated garden crops maintained in home gardens and dating back at least to the 1950s have been assembled following the nationwide ‘Seed Call’. Of these, 32 garden pea accessions were taxonomically characterized and compared with 43 accessions already present in the gene bank. In addition to morphological descriptors, SSR and retrotransposon-based iPBS markers were applied. Based on five SSR markers, potential duplicates could be located within nine pair/gro…
The Genus Homo: Origin, Speciation and Dispersal
2011
The taxonomical interpretation of the fossil record of our own genus Homo is still highly controversial. In spite of obvious major advances concerning the acquisition, analysis and interpretation of the fossil specimens there currently remain unbridgeable disagreements concerning the origin, speciation and dispersal of our genus. The polarized positions result foremost from different methodological approaches for species recognition (e.g., Tattersall 1986; Wolpoff and Caspari 1997; Schwartz 2000a; Wiesemuller et al. 2003; Jobling et al. 2004; Rothe and Henke 2006). Beside the Multiregional Evolutionary Model (MRE) there are different Recent African Origin Models (RAOMs) with varying numbers…
Seed isozyme variation in Petrocoptis A. Braun (Caryophyllaceae).
2001
Abstract The electrophoretic patterns of seven isozyme systems (ADH, AMY, AAT, GDH, LAP, MDH, and SOD) obtained from dormant seeds from 44 accessions belonging to 12 Petrocoptis taxa were compared in order to clarify taxonomic relationships within the genus. Overall, electrophoretic zymograms showed the presence of up 28 electromorphs, of which 26 were polymorphic among accessions. Mantel tests revealed a moderate level of correlation between the geographic distance matrix and several dissimilarity matrices based on the isozyme data ( r =0.3052–0.3376). The electrophoretic profiles of seed isozymes did not match closely the analytical taxonomic framework drawn from morphology. Many electrom…
Perception and consumption of alcohol among the immigrant population from Latin America in Valencia region (Spain).
2010
This study examines patterns of alcohol consumption among the Hispanic immigrant population in Valencia (Spain), and also whether the length of immigrants’ residence in our country and perceived degree of discrimination have any influence on such patterns. A total of 610 Spanish-speaking immigrants (314 women, 296 men) over 15 years of age, from six Hispano-American countries were interviewed in 2006; 76.8% had consumed alcohol in the previous 12 months; 37.6% drink more alcohol in Spain than in their country of origin. This study shows the need to develop specific programs for the immigrant population, with special consideration for the young, males, and smokers. The study's limitations ar…
A Bibliometric Analysis of Fragility Fractures: Top 50.
2021
Background and Objectives: The population is aging and fragility fractures are a research topic of steadily growing importance. Therefore, a systematic bibliometric review was performed to identify the 50 most cited articles in the field of fragility fractures analyzing their qualities and characteristics. Materials and Methods: From the Core Collection database in the Thomson Reuters Web of Knowledge, the most influential original articles with reference to fragility fractures were identified in February 2021 using a multistep approach. Year of publication, total number of citations, average number of citations per year since year of publication, affiliation of first and senior author, geo…
Differences in weight status and energy-balance related behaviours according to ethnic background among adolescents in seven countries in Europe: the…
2012
Objective The aim of this study was to explore differences in weight status and energy balance behaviours according to ethnic background among adolescents across Europe. Methods A school-based survey among 10–12-year-old adolescents was conducted in seven European countries. Weight, height and waist circumference were measured; engagement in physical activity, sedentary and dietary behaviour, and sleep duration was assessed by child and parent-report. A distinction between native and non-native ethnic background was based on language spoken at home, and the parents' country of birth. Analyses were conducted with and without adjustment for parental education. Results With valid data on both …

Glochidial infection by the endangered Margaritifera margaritifera (Mollusca) increased survival of salmonid host (Pisces) during experimental Flavob…
2021
AbstractCo-infections are common in host-parasite interactions, but studies about their impact on the virulence of parasites/diseases are still scarce. The present study compared mortality induced by a fatal bacterial pathogen, Flavobacterium columnare between brown trout infected with glochidia from the endangered freshwater pearl mussel, Margaritifera margaritifera, and uninfected control fish during the parasitic period and after the parasitic period (i.e. glochidia detached) in a laboratory experiment. We hypothesised that glochidial infection would increase host susceptibility to and/or pathogenicity of the bacterial infection. We found that the highly virulent strain of F. columnare c…
