The sequence diversity in the mitochondrial cytochrome-c oxidase I (COI) gene was evaluated as a tool for resolving differences among species of European adelgids collected from several localities across the Czech Republic. Members of 7 genera and 16 species were examined, and as outgroups, two species of Phylloxeridae were used. Sequence divergences within species were on average less than 0.15%, whereas divergences between species ranged from 0.0 to 4.12% for congeneric and to 13.24% for intergeneric comparisons. It is concluded that DNA barcoding of Adelgidae is a powerful tool for identifying genera, but at the species level it works only in those cases where there are no species complexes. Nevertheless, it can be used as a complement to traditional, morphological taxonomy.
A hybrid approach to elephant trunk technique for treatment of thoracic aortic aneurysms combines a conventional surgical and endovascular therapy. Compared to surgery alone, there is a presumption that mortality and morbidity is reduced. We present a case report of a 42-year-old man with a giant aneurysm of the entire thoracic aorta, significant aortic and tricuspid regurgitation and ventricular septum defect. The patient underwent multiple consecutive operations and interventions having, among others, finally replaced the entire thoracic aorta with the use of the hybrid elephant trunk technique. and T.

This study examines the possibilities and limitations of centralizing reforms within the western part of the Habsburg monarchy, as illustrated by the problematic issue of ennoblement in the Czech lands. The administrative reforms of 1749 resulted in the administrative union of both state entities in a single whole of (all) so-called Hereditary Lands. They also led to the closure of separate offices at court representing the Czech and Austrian lands, replacing them with a single Directorium in publicis et cameralibus, which took over the ennoblement programme hitherto operated by those two offices. Despite the apparently centralizing tendency of the reforms, this did not extend to any unification of entitlements to ennoblement, which continued to be based on particular ranks and titles specific to either the Kingdom of Bohemia or the Archduchy of Austria. It was not until 1752 that, on the urging of Maria Theresa herself, a unified, legally binding system for dispensing preferment and privilege, including a unified scale of aristocratic titles for all the Hereditary Lands, was introduced. In practice, ennoblement rights in the two state entities remained differentiated as to specific titles up until the early 19th century, when the two systems were superseded by a new Austrian Imperial ranking. Thus one of the last relics of the conception of the Czech Crown Lands as an autonomous historical entity finally ceased to exist., Jiří Brňovják., and Obsahuje bibliografické odkazy
