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.

The main aim of this paper is to propose an adequate interpretation of the concept esse apparens (apparent being) which was used by Franciscan philosopher and theologian Peter Auriol (c. 1280-1322), especially focusing on his account of sensory perception. Drawing on an analysis of the relevant passages of the commentary on the Sentences by Auriol, first, I introduce his famous account of sensory illusions, and then his own claims about the nature of esse appparens (Auriol refuses to treat it either as a separate entity serving as a mediator of perception, or as only an extrinsic denomination of the perceived object). In the next part, I reject the interpretation which identifies esse apparens with mental representation. In my opinion, it is more appropriate to place this concept into the context of scholastic doctrine of objectiver or intentional being (popularized mainly by Duns Scotus and his disciples). At the end of the paper, I return to Auriol's account of illusions and show that it is compatible with esse apparens being understood as mode of being., Lukáš Lička., and Obsahuje poznámky a bibliografii
Autoři prezentují případ vzácného ?inverzního? syndromu Fostera-Kennedyho, který byl zpočátku zdrojem diagnostických rozpaků. Na základě klinických příznaků a výsledků grafických vyšetření autoři diskutují původ klinických projevů, jehož příčinou byl nitrolební meningeom. Pokud se nepodaří uspokojivě vysvětlit klinické příznaky ? centrální skotom s atrofií papily nebo druhostranné městnání na očním pozadí očním původem, je třeba včas indikovat grafická vyšetření mozku a vyloučit intrakraniální tumor., Zlatica Dúbravská, S.

Biologie dekompozitorů byla vždy tak trochu na druhé koleji širšího vědeckého i veřejného zájmu. Není se trochu čemu divit – než se přehrabovat v něčem nevábném, je pohodlnější pozorovat zvířata na rostlinách či jejich predátory. Nicméně dekompozitoři si naši pozornost zaslouží už jen tím, že po nás uklízejí, ať jde o kontinuální úklid koprofágů, tak o jednorázový úklid, který po nás provedou nekrofágové, a tím pomáhají udržovat to krásné a přitažlivé v chodu a stabilitě. Z koprofágů se již od věků pyramid těší jisté pozornosti koprofágní brouci, nicméně za poslední léta o nich v naší literatuře mnoho slyšet nebylo. Cílem tohoto článku je tedy představit širší veřejnosti tyto koprofágní brouky s jejich osobitou a zajímavou ekologií, která zajímavě ovlivnila jednu lidskou kulturou., Dung beetles are introduced as an important and interesting ecological group. Their ecology, what they eat and their impact on human culture and society are reviewed. Although they are no longer considered to be a deity, dung beetles still prove to be highly beneficial for both nature and human society, thanks to their degradation of dung., and František Xaver Jiří Sládeček.
The Grounds of Concrete Logic (Základové konkretné logiky) is often taken to be a work in which Masaryk attempts to outline, in a methodical way, his conception of philosophy as “a real scientific metaphysics”. Nevertheless, we often hear from the Masaryk’s critics, and even from his followers, that the book appears to be no more than a transcription of Comte’s Cours de philosophie positive. Even if the classification of the
sciences was one of the main philosophical and scientific problems with which Masaryk was engaged throughout his life, in the emphasis on concrete sciences, and in the working out of the relations between particular sciences and categories, Masaryk goes beyond Comte. This point is supported, at the same time, by the many critical notes concerning the inadequacy of Comte’s epistemological grounding, which Masaryk links, above all, to a critique of Comte’s phenomenalism. The specific quality and the critical reference of the book for future generations of Czech philosophers consists in its principled status and realist aim. Concrete logic should bring us to the ultimate ontological points of departure – to things themselves. In his prioritising of the need to seek the sense of things, Masaryk belongs to the modern thinkers who showed to Czech philosophy new possibilities and ways of approach to reality in a strictly scientific spirit.
