Moderní kardiovaskulární rehabilitace u pacientů s chronickým srdečním selháním (CHSS) je v zahraničí chápána jako multidisciplinární proces. I přes obrovské pokroky v léčbě tohoto těžkého onemocnění není zatím v České republice věnována prakticky žádná pozornost ambulantní rehabilitační péči o nemocné s chronickým srdečním selháním. Přitom vhodně nastavená pohybová aktivita prokazatelně zvyšuje kvalitu života a omezuje náklady na léčbu těchto nemocných. Tento přehledový článek poukazuje na velký přínos kardiovaskulární rehabilitace pro pacienty s CHSS. Klíčová slova: chronické srdeční selhání – kombinovaný trénink – aerobní kapacita – kvalita života – Threshold IMT – inspirační svalstvo, Foreign specialists understand modern cardiac rehabilitation in patients with chronic heart failure (CHF) as a multidisciplinary process. Despite huge advances in the treatment of this severe disease in the Czech Republic, virtually no attention is paid to outpatient rehabilitation care for these patients, although appropriately chosen physical activity demonstrably improves quality of life and reduces the cost of treatment provided to these patients. This review highlights the great benefits of cardiac rehabilitation for patients with CHF. Keywords: chronic heart failure – combined training – aerobic capacity – quality of life – Threshold IMT – inspiratory muscle, and Dosbaba F., Žurková P., Ludka O., Vysoký R., Baťalík L., Špinar J., Kolařík O.
This paper describes the first study of the diatom assemblages in caves in the Czech Republic. The study focused on subaeric habitats: rock faces within caves, walls at cave entrances and “lampflora” assemblages, in three cave systems, Mladeč, Javoříčko and Zbrašov, all in central Moravia. The morphological and cytological variability, ecology and life strategies of diatoms were studied in fresh samples, in Naphrax preparations, in cultures grown on agar plates and in monoclonal cultures. A total of 22 diatom species was identified, mostly aerophytic species and tolerant of low light intensities. Luticola and Diadesmis species complexes are discussed. Taxa D. gallica and L. paramutica var. binodis are new for the Czech Republic. Sexual reproduction was observed in L. mutica and Orthoseira roeseana.
Only in the southern part of the Iberian Peninsula the large white butterfly Pieris brassicae was recorded to pass the summer in pupal aestivation, induced by long-day photoperiods. It is not clear why this photoperiodic response is regionally restricted. We investigated whether the change of life history in P. brassicae may affect the infestation by parasites. This was done by testing the coincidence of photoperiodic responses in both the host P. brassicae and in its main parasitoid Cotesia glomerata. While the response under short-day conditions was very similar in both species, no summer dormancy of any type was found in the parasitoid at photophases >= 15h and temperatures of 15°-25°C in contrast to 100% aestivation in the host. We suggest that aestivation is a response which allows the host to desynchronise its life cycle from that of its parasitoid. This is effective because parasitoid wasps cannot pass the temporary absence of suitable host stages by a similar developmental rest. C. glomerata is then forced to switch to less adequate host species which diminishes its reproductive success.
