Dvořák, his Librettists, and the Working Libretto for ‘Armida’

From the late 1860s, opera for Dvorák, along with many composers of the Czech national revival, was an abiding preoccupation. This article examines Dvorak’s relationship with his librettists, his approach to their texts, and the extent to which he was prepared to mould their content. While there is no surviving correspondence between Dvorák and the librettist of his last opera, Jaroslav Vrchlický, a copy of the libretto of Armida with annotations in both Vrchlický’s and Dvorák’s hands was found in 2007 among the writer’s papers. Although Dvorák’s stage sense has often been called into question, it is clear that his interventions in the libretto of Armida, in the first and last acts in particular, show a practical, theatrical approach that did much to enhance the dramatic impact of Armida’s first entry and the final chorus of the opera.

The Reception of Byzantium in European Culture since 1500

Studies on the reception of the classical tradition are an indispensable part of classical studies. Understanding the importance of ancient civilization means also studying how it was used subsequently. This kind of approach is still relatively rare in the field of Byzantine Studies. This volume, which is the result of the range of interests in (mostly) non-English-speaking research communities, takes an important step to filling this gap by investigating the place and dimensions of ‘Byzantium after Byzantium’.
This collection of essays uses the idea of ‘reception-theory’ and expands it to show how European societies after Byzantium have responded to both the reality, and the idea of Byzantine Civilisation. The authors discuss various forms of Byzantine influence in the post-Byzantine world from architecture to literature to music to the place of Byzantium in modern political debates (e.g. in Russia). The intentional focus of the present volume is on those aspects of Byzantine reception less well-known to English-reading audiences, which accounts for the inclusion of Bulgarian, Czech, Polish and Russian perspectives. As a result this book shows that although so-called 'Byzantinism' is a pan-European phenomenon, it is made manifest in local/national versions.
The volume brings together specialists from various countries, mainly Byzantinists, whose works focus not only on Byzantine Studies (that is history, literature and culture of the Byzantine Empire), but also on the influence of Byzantine culture on the world after the Fall of Constantinople.

Monoclonal antibody development for acrylamide-adducted human haemoglobin; A biomarker of dietary acrylamide exposure

The spontaneous formation of the neurotoxic carcinogen acrylamide in a wide range of cooked foods has recently been discovered, leading to dietary exposure estimates of 30.8 mu g of acrylamide day(-1) for an average 77 kg human male. This is considerably higher than the European legal limit of acrylamide in drinking water, which is approximately 0.2 mu g of acrylamide person(-1) day(-1). A recent study of 62,573 women over 11.3 years has observed an increased risk of postmenopausal endometrial and ovarian cancer (but not breast cancer) with increasing dietary acrylamide intake, demonstrating significant risk to human health. As individual acrylamide exposure is affected by dietary habits, cooking methods, and cigarette consumption; accurate extrapolation from estimated dietary exposure is extremely difficult. Quantifying biomarkers of acrylamide exposure therefore remains the most effective means of rapidly determining individual exposure to acrylamide, and correlating exposure with lifestyle choices. Current methodologies for the analysis of blood biomarkers of acrylamide are focused on expensive, slower chromatographic techniques such as GC and LC coupled to mass spectrometry. This paper describes the first successful development of two monoclonal antibodies specific to acrylamide-adducted haemoglobin (IC50 of 94 ng ml(-1) and 198 ng ml(-1)), that are suitable for use in a high-throughput biomarker immunoassay to determine individual acrylamide exposure. Further development of acrylamide-haemoglobin standards with defined levels of acrylamide adduction will enable a fully quantitative assay, and allow sensitivity comparisons with alternative chromatographic methods of analysis.

Multiple origins of European populations of giant liver fluke Fascioloides magna (Trematoda: Fasciolidae), an invasive liver parasite of ruminants

The giant liver fluke, Fascioloides magna, liver parasite of free-living and domestic ruminants of Europe and North America, was analysed in order to determine the origin of European populations and to reveal the biogeography of this originally North American parasite on the European continent. The previously selected variable fragments of the mitochondrial cytochrome c oxidase subunit I (cox1; 384 bp) and nicotinamid dehydrogenase subunit I (nad1; 405 bp) were applied as a tool. The phylogenetic trees and haplotype networks were constructed and the level of genetic structuring was evaluated using population genetic tools. In F. magna individuals originating from all European natural foci (Italy, Czech Republic, Danube floodplain forests) and from four of five major North American enzootic areas, 16 cox1 and 18 nad1 haplotypes were determined. The concatenated sequence set produced 22 distinct haplotypes. The European fluke populations were less diverse than those from North America in that they contained proportionately fewer haplotypes (8), while more substantial level of genetic diversity and higher number of haplotypes (15) were recorded in North America. Only one haplotype was shared between the European (Italy) and North American (USA/Oregon and Canada/Alberta) flukes supporting a western North American origin of the Italian F. magna population. Haplotypes found in Italy were distinct from those determined in the remaining European localities what indicates that introduction of F. magna onto the European continent is a result of more than one event. In Czech focus, a south-eastern US origin of giant liver fluke was revealed. Identical haplotypes, common for parasites from Czech Republic and from expanding focus of Danube floodplain forests, implies introduction of F. magna to the Danube region from an already established Czech focus.
