- Description:
- Ground concentration of ozone (O3) causes serious threat to plants. In order to protect sensitive plants from O3 pollution, many kinds of antioxidants were assessed in previous studies. In this study, effects of O3 fumigation (a single spike of 120 ± 20 nmol mol-1 for four hours) on an ornamental species (Coleus blumei) was examined in open-top chambers. Before the O3 treatment, plants were sprayed respectively either with a solution of three different antioxidants [Na-ascorbate (NaAsA), kinetin (KIN), and spermidine (Spd)] or with distilled water to compare their protective effects to plants. Our results revealed that O3 fumigation impaired the plasma membrane, decreased chlorophyll (Chl) content, inhibited photosynthesis, induced photoinhibition and photodamage, and caused visible injury. Spraying with KIN, NaAsA or Spd ameliorated the decrease of the Chl content and photosynthetic capability, the impairment of membrane, and visible injury under O3 fumigation. The plants treated with KIN showed the best ability to mitigate the injury caused by O3., L. Zhang, L. L. Jia, J. X. Sui, M. X. Wen, Y. J. Chen., and Obsahuje bibliografii

- Description:
- Salicylic acid (SA) and polyamines (PA) are widely used to overcome various abiotic stresses including salt (NaCl) stress in plants. In the present investigation, co-application efficacies of SA and PA on the salt stress (200 mM NaCl) were evaluated in Lycopersicon esculentum. After transplantation, at 10-d stage, seedlings were exposed to NaCl through soil and then allowed to grow till 30-d stage. At 31-d stage of growth, plants were sprayed with double distilled water (control) or spermidine (1.0 mM) and/or SA (10-5 M). The salt stress significantly reduced the growth, gas-exchange parameters, but increased antioxidant enzymes and proline content in the leaves. Moreover, the loss caused by salt stress was successfully restored by the following treatment of spermidine and SA., Q. Fariduddin, T. A. Khan, M. Yusuf, S. T. Aafaqee, R. R. A. E.

- Description:
- V ČR a Polsku se v posledním období významným zahraničněpolitickým i vnitropolitickým tématem stal záměr vlády USA umístit v těchto zemích některé komponenty budovaného amerického systému obrany proti mezikontinentálním balistickým střelám, který by podle deklarovaného záměru měl chránit kontinentální území Spojených států před případným útokem prostřednictvím menšího počtu raket dlouhého doletu z tzv. „ničemných států“ (rogue states), jak je označuje americká administrativa. Vlády ČR a Polska byly v tomto směru nedávno oficiálně americkou stranou požádány diplomatickou nótou o jednání v této záležitosti. V případě Polska by se mělo jednat o odpalovací zařízení raket určených k ničení mezikontinentálních balistických střel, na českém území by pak měl být dislokován radar, jehož prostřednictvím protiraketový systém vyhledává nepřátelské střely a navádí na ně své rakety. Probíhající diskuse jak uvnitř obou oslovených středoevropských států, tak i na mezinárodním foru zřetelně ukazují, že jak konkrétní plán umístit základny antibalistické obrany v ČR a Polsku, tak zejména samotný záměr budovat byť i jen omezený systém strategické obrany tohoto druhu, představuje závažnou, značně citlivou a kontroverzní otázku s globálním dosahem. Pochopitelný a průběžně sílící zájem o věc projevují také obyvatelé obou zemí. A právě postojům české a polské veřejnosti k celému projektu, jejich aktuálnímu stavu a také možnému dalšímu vývoji se bude věnovat tento text., The text focuses on public opinion in Czech Republic and Poland relating to the plan of U.S. government to locate some parts of U.S. national missile defence in these countries. It describes and compares main shifts of developments of public attitudes in both countries to the project as well as to eventual referendum in this matter within the period up to the first half of 2007. The text shows main demographical, societal and political differences in both countries and discusses reasons and motives behind particular attitudes of Czech and Polish citizens., Jan Červenka., and Seznam literatury

- Description:
- Publikace podle recenzenta přináší zajímavý pohled na slovenský autonomistický proud v meziválečném Československu z dosud nezpracovaného úhlu, a to optikou amerických a kanadských Slováků. Nejedná se pouze o přehledovou práci o slovenském autonomistickém hnutí, nýbrž také o hlubokou sondu do politického, náboženského a kulturního prostředí severoamerických krajanů, jež mělo významný vliv na aktivitu slovenského politického hnutí v první Československé republice. Autor dokumentuje jak vztahy a kontakty politiků na Slovensku s krajanskou obcí v Severní Americe, tak proměny jejích názorů na státoprávní uspořádání Československa a postavení Slováků v něm, které dospěly přes počáteční dílčí rozpory k jednoznačnému autonomistickému stanovisku., This publication, whose title translates as ‘The American Slovaks’ contribution to the movement for an autonomous Slovakia, 1918-38’, provides, according to the reviewer, an interesting view of a trend in inter-war Czechoslovakia seen from the hitherto ignored angle of the Slovaks living in the USA and Canada. This is not only a general survey of the movement for Slovak autonomy; it is also an in-depth examination of the political, religious, and cultural milieux of Slovaks living in North America, which had an important influence on the Slovak political movement in the first Czechoslovak Republic. The author documents the relations between politicians in Slovakia and the Slovak communities in North America, and also discusses the changes in their views on the constitutional arrangement of Czechoslovakia and the Slovaks’ status within it, which led, despite initial conflicts, to a clear autonomist stance., [autor recenze] Marek Šmíd., and Obsahuje bibliografii

- Language:

- Description:
- In laboratory experiments, conspecific excretions and ammonia solutions evoked avoidance reactions in tadpoles of three anuran species, Bufo bufo, Rana temporaria, and Rana arvalis . A differential sensitivity of ammonia chemoreception was determined for two anuran species. For Bufo bufo tadpoles, these characteristics at ammonia backgr ound concentration of 0.2 mg/l lied in the range 150 % < dI/I < 500 %, and for background of 0.4 mg/l the value lied in th e range 400 % < dI/I < 500 %. For Rana temporaria tadpoles, differential threshold against ammonia background concentration of 0. 15 mg/l was close to 200 % and against background ammonia concentration of 1.1 mg/l was close to 100 %. These results suggest that such sensitivity of both anurans is sufficient for using ammonia in intra- and interspecies communication., Y. B. Manteifel, E. I.

- Language:
- English
- Description:
- Metabotropic glutamate receptors (mGluRs) represent a potential therapeutic target. Possible anticonvulsant action of AMN 082, an agonist of mGluR7 subtype, was studied in immature rats using pentylenetetrazol (PTZ)-induced seizures as a model. Five age groups of rats (7-, 12-, 18-, 25-day-old and adult animals) were pretreated with AMN 082 in doses of 0.5, 1, 2, and 5 mg/kg i.p. and 30 min later PTZ was administered (100 mg/kg s.c.). Controls received saline instead of the agonist. AMN 082 did not exhibit clear anticonvulsant action with the exception of suppression of the tonic phase of generalized tonic-clonic seizures (GTCS) in 12-day-old rats. Shorter latencies of GTCS after AMN 082 pretreatment indicate a proconvulsant action. Involuntary movements (mostly tremor) appeared after AMN 082 before PTZ administration, therefore we performed another experimental series with AMN 082 only (1, 2, 5, and 10 mg/kg i.p.). During 60-min observation period tremor appeared in all age groups; sensitivity to this action decreased with age from the 2 mg/kg dose in 7- and 12-day-old rats to the 10 mg/kg dose in adult rats. Mixed anti- and proconvulsant actions of AMN 082 together with unwanted motor effects makes clinical use of this drug highly improbable., Pavel Mareš., and Obsahuje bibliografii a bibliografické odkazy

- Description:
- Three amoeba species were isolated from 3 out of 193 farmed tilapias, Oreochromis niloticus (L.), screened for the presence of free-living amoebae in parenchymatous organs. Hartmannella vermiformis Page, 1967 and Rosculus ithacus Hawes, 1963 were isolated from the kidney tissue. The third strain isolated from the liver shared morphological features of Mayorella and Platyamoeha spp. and therefore its taxonomic position has not been determined as yet. Pathogenicity of cloned strain of H. vermiformis was proved in two fish hosts.

- Format:

- Subject:
- amoebic infection, Scophthalmus maximus, and mariculture
- Language:
- English
- Description:
- Amoebae were found to cause severe gill tissue damage in turbot, Scophthalmus maximus L. from a grow-out facility in northwestern Galicia (Spain). The nature and extent of lesions along with negative results of bacteriological and virological examination made this agent responsible for mortalities in four turbot stocks supplied with water from a single source. We present our findings, although we failed to isolate amoebae, since there was a clear evidence of their primary role in the development of disease condition and occurrence of mortalities. In addition, this is a record both of a new host endangered by amoebae in intensive cultures and pathogenesis of the gill lesions.
