Examination of a total of 581 fish specimens of 15 species from 39 cenotes (sinkholes) in the Yucatan Peninsula, southeastern Mexico, revealed the presence of 10 species of adult trematodes. These were as follows: Saccocoelioides sogandaresi Lumsden, 1963, Saccocoelinides sp. (family Haploporidae), Cichlasotrema ujati Pineda et Andrade, 1989 (Angiodictyidae), Crassicutis cichlasomae Manter, 1936 (Homalometridae), Magnivitellinum simplex Kloss, 1966 (Macroderoididae), Stunkardiel-la minima (Stunkard, 1938) (Acanthostomidae), Oligogonotylus manieri Watson, 1976 (Cryptogonimidae), Genarchella tropica (Manter, 1936), G. astyanactis (Watson, 1976), and G. isabellae (Lamothe-Argumedo, 1977) (Derogenidae). Saccocoelioides sogandaresi is reported from Mexico for the first time. Poecilia velifera and P. latipunctata for S. sogandaresi, Cichlasoma octo-fasciatum for C. cichlasomae, Cichlasoma friedrichslahli and C. meeki for O. manieri, and C. meeki, C. octofasciatum and Go-hiomorus dormitor for C. isabellae represent new host records. Most species found are described and figured and their host range
The aim of this study was to compare the central and peripheral components of cardiorespiratory fitness during incremental to maximal exercise between older men who were either recreational athletes (RA) or leisurely active (LA) men, i.e., those who fall between trained and untrained. This was a crosssectional study in which all subjects completed an exercise test on a cycle ergometer. Maximal oxygen consumption (VO2max) and ventilatory threshold (VT) were assessed using gas analysis, and central components of VO2max were assessed using a non-invasive thoracic bio-impedance device. VO2max (RA: 45.1±4.8 ml/kg/min; LA: 32.2±4.6 ml/kg/min, p≤0.001) and SV at maximal exercise (RA: 133.5±24.96 ml/beat; LA: 107.9±17.6 ml/beat, p=0.005) were higher in the RA group compared to the LA group. A plateau in SV occurred between 30-45 % of maximal exercise capacity in the RA group. No differences in SV were observed across workloads in the LA group. No differences in the calculated arterio-venous oxygen difference ((a-v)O2diff) were observed between groups. In conclusions, training volume appears to influence central components of cardiorespiratory fitness among a matched sample of older men who are neither trained nor untrained. This builds a case for increasing the volume of training to preserve cardiorespiratory fitness among older men., C. D. O'neill, D. S. Kimmerly, S. Dogra., and Obsahuje bibliografii
Rilmenidin je antihypertenzivum ze skupiny agonistů imidazolinových receptorů. Podstatou jeho mechanizmu účinku je výrazné snížení kardiální a renální sympatické baroreflexní odpovědi na úrovni I1-imidazolinových receptorů s následným snížením aktivity sympatiku. Účinnost a snášenlivost rilmenidinu byly prokázány v randomizovaných srovnávacích studiích u starších pacientů, hypertoniků s diabetem a metabolickým syndromem i u pacientů s renálním selháním. Indikací pro podávání rilmenidinu je léčba esenciální hypertenze u dospělých pacientů všech věkových kategorií. Doporučená dávka je 1 mg denně (ráno)., Rilmenidine is an antihypertensive from the group of imidazoline receptor agonists. The basis of its mechanism of action is significant reduction of cardiac and renal sympathetic baroreflex response at the level of I1-imidazoline receptors with subsequent reduction of the sympathetic activity. The effectiveness and tolerability of rilmenidine were proved in randomized comparative studies in elderly patients, patients suffering from hypertension together with diabetes and metabolic syndrome, and in patients with renal failure. The indication for administering rilmenidine is treatment of essential hypertension in adult patients of all age groups. The recommended dose is 1 mg a day (in the morning)., and Souček M.
CORDIS, a new service Unique Registration Facility (URF), was launched on April 27. It will facilitate the preparation of grant agreements between participants and the European Commission. Thanks to the new service, participants in the Seventh Framework Programme (FP7) and other programmes managed by the Research Directorate General will no longer have to submit their legal and financial information each time a new grant agreement is in the pipeline. Once participants have been validated by the European Commission´s central validation team for their existence as legal entities and their legal status they will only have to submit their Participant Identification Code (PIC). and Lenka Lepičová.
The aim of the Center is to focus on selected branches of basic research in developmental biology, biocompatible polymer synthesis, neuroscience and transplant surgery into one organic whole. This scan serve as an experimental foundation for cell therapy and tissue repair research on a level qualitatively comparable to research in the developed countries of the EU and the USA. and Eva Syková.
