Hazard characterization of the mycotoxins enniatins and beauvericin to identify data gaps and improve risk assessment for human healthNARA Subscribed
Enniatins (ENNs) and beauvericin (BEA) are cyclic hexadepsipeptide fungal metabolites which have demonstrated antibiotic, antimycotic, and insecticidal activities. The substantial toxic potentials of these mycotoxins are associated with their ionophoric molecular properties and relatively high lipophilicities. ENNs occur extensively in grain and grain-derived products and are considered a food safety issue by the European Food...
Late Antiquity Dalmatia was a time and place of political unrest in the Roman Empire that influenced the lives of those in that region. The Late Antique burial site of Hvar – Radošević, spanning the 3rd to 5th centuries CE, is located on the Croatian Dalmatian island of Hvar. Given the time frame and location on a busy marine trade route, the study of this burial site offers us a glimpse into the lives of the Late Antique popu...
Revealing the nuclearity of iron citrate complexes at biologically relevant conditionsNARA Subscribed
Citric acid plays an ubiquitous role in the complexation of essential metals like iron and thus it has a key function making them biologically available. For this, iron(III) citrate complexes are considered among the most significant coordinated forms of ferric iron that take place in biochemical processes of all living organisms. Although these systems hold great biological relevance, their coordination chemistry has not been...
Hazard characterization of Alternaria toxins to identify data gaps and improve risk assessment for human healthNARA Subscribed
Fungi of the genus Alternaria are ubiquitous plant pathogens and saprophytes which are able to grow under varying temperature and moisture conditions as well as on a large range of substrates. A spectrum of structurally diverse secondary metabolites with toxic potential has been identified, but occurrence and relative proportion of the different metabolites in complex mixtures depend on strain, substrate, and growth conditions...
Exploring connectivity in Late Bronze Age/Early Iron Age Greece and the Balkans using cranial non-metric analysisNARA Subscribed
The present study aims to explore connectivity and networking in Late Bronze Age (LBA)/Early Iron Age (EIA) Greece and the Balkans using morphological biodistance analysis and test the potentiality of newly introduced statistical tests, which were designed for challenging datasets, in this particular cultural area. Cranial non-metric traits were recorded in ten skeletal collections, spanning from East Crete to Romania. We foll...
Arctic landscapes are warming and becoming wetter due to changes in precipitation and the timing of snowmelt which consequently alters seasonal runoff and river discharge patterns. These changes in hydrology lead to increased mobilization and transport of terrestrial dissolved organic matter (DOM) to Arctic coastal seas where significant impacts on biogeochemical cycling can occur. Here, we present measurements of dissolved or...
Biochemical and Physicochemical Background of Mammalian Androgen Activity in Winter Wheat Exposed to Low TemperatureNARA Subscribed
Understanding of the physiological role of mammalian hormone—androstenedione (AN)—in plants is scant and the mechanisms of its action at a cellular level are practically unknown. The aim of this study was to investigate the physicochemical and biochemical background of AN activity in winter wheat exposed to low temperature. Cold periods are important in the lifecycle of this species as they induce frost resistance and further...
Structure and mechanism of diet specialisation: testing models of individual variation in resource use with sea ottersNARA Subscribed
Ecology Letters (2012) 15 : 475–483 Abstract Studies of consumer‐resource interactions suggest that individual diet specialisation is empirically widespread and theoretically important to the organisation and dynamics of populations and communities. We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual spec...
