- Description:
- The moths belong to the best-studied groups of insects in the Podyjí NP. In total, 2250 species of butterflies and moths (Lepidoptera) have hitherto been recorded here. Many species are closely associated with rocky steppe and heeathland, the most valuable natural habitats in this terriotory. Concurrently, the Podyjí NP is located on the western distribution border of many eastern and southern species. On the other hand, a total of 13 species of butterflies and moths have now become extinct here. and Jan Šumpich, Jan Liška, Zdeněk Laštůvka.

- Description:
- The main objective of the management of woodland in the Podyjí National Park (NP) is to allow natural processes and support biodiversity. How the woodland has changed since designation of the NP is illustrated by changes in selected parameters (tree species composition, proportion of dead wood etc.). Some active measures to support woodland biodiversity are also presented in the paper. and Jaroslav Ponikelský a kolektiv spoluautorů.

- Subject:
- Biologické vědy, motýli, národní parky, butterflies, national parks, Národní park Podyjí (Česko), Podyjí National Park (Czechia), 2, and 57/59
- Language:
- Czech
- Description:
- The Podyjí NP has very diverse vegetation which results in the occurrence of rich butterfly communities. To date, 142 species of butterflies have been recordeed in this area, of which 19 species (13 %) are considered regionally extinct and three species (2 %) are only migrants, not native to the Czech fauna. The main cause of the decline in butterflies is the abandonment of traditional techniques of habitat management. To conserve and support butterfly diversity, the NP authority practices a wide range of management measures. and Milan Švestka.

- Description:
- The ameliorative role of 28-homobrassinolide under chilling stress in various growth, photosynthesis, enzymes and biochemical parameters of cucumber (Cucumis sativus L.) were investigated. Cucumber seedlings were sprayed with 0 (control), 10-8, or 10-6 M of 28-homobrassinolide at the 30-day stage. 48 h after treatment plants were exposed for 18 h to chilling temperature (10/8°C, 5/3°C). The most evident effect of chilling stress was the marked reduction in plant growth, chlorophyll (Chl) content, and net photosynthetic rate, efficiency of photosystem II and activities of nitrate reductase and carbonic anhydrase. Moreover, the activities of antioxidant enzymes; catalase (E.C. 1.11.1.6), peroxidase (E.C.1.11.1.7), superoxide dismutase (E.C. 1.15.1.1) along with the proline content in leaves of the cucumber seedlings increased in proportion to chilling temperature. The stressed seedlings of cucumber pretreated with 28-homobrassinolide maintained a higher value of antioxidant enzymes and proline content over the control suggesting the protective mechanism against the ill-effect caused by chilling stress might be operative through an improved antioxidant system. Furthermore, the protective role of 28-homobrassinolide was reflected in improved growth, water relations, photosynthesis and maximum quantum yield of photosystem II both in the presence and absence of chilling stress. and Q. Fariduddin ... [et al.].

- Language:
- Czech
- Description:
- The creation of Czechoslovakia in 1918 was the culmination of the long struggle of the Czechs against their Austrian rulers and of the Slovaks against their Hungarian rulers. At the outbreak of World War I, the Czechs and Slovaks showed little enthusiasm for fighting for their respective enemies, the Germans and the Hungarians, against fellow Slavs, the Russians and the Serbs. In 1916, together with Edvard Beneš and MIlan Rastislav Štefánik, Masaryk created the Czechoslovak National Council. In early October 1918, Germany and Austria proposed peace negotiations. On October 28, the National Committee issued a declaration of Czechoslovak independence. and Ivan Šedivý.

- Description:
- Odlupováním vrstevnatých materiálů (např. grafitu) lze připravit 2D krystaly s tloušťkou jednoho nebo několika málo atomů. Nejznámějším takovým 2D materiálem je grafen (monovrstva grafitu), nicméně v současnosti existují a intenzivně se zkoumají desítky podobných struktur. Příspěvek podává základní přehled o 2D materiálech, jejich vlastnostech, metodách přípravy a možných aplikacích., Layered materials (such as graphite) can be exfoliated to produce 2D crystals with a thickness of one of just a few atoms. The best known 2D material is graphene (monolayer of graphite), yet there are tens of similar structures, which are being studied intensively at the moment. This article presents a brief summary of 2D materials, their properties, methods of preparation and potential application., Zdeňka Hájková, Martin Ledinský, Matěj Hývl, Aliaksei Vetushka, Antonín Fejfar, Jaroslava Řáhová, Otakar Frank., and Obsahuje bibliografické odkazy

- heroin self-administration, 2Hz-electroacupuncture, heroinseeking behaviors, and CB1-Rs and CB2-Rs
- Language:
- English
- Description:
- Opiate addiction has a high rate of relapse. The accumulating evidence shows that electroacupuncture (EA) may be effective for the treatment of opiate relapse. However, the change of expression of CB1-Rs and CB2-Rs involve in 2Hz EA anti-relapse pathway is still unclear. To explore the changes of expression of CB1-Rs and CB2-Rs, heroin self-administration (SA) model rats were adopted and treated using 2Hz EA. The expressions of CB1-Rs and CB2-Rs were observed using immunohistochemistry method. The results showed that, compared with the control group, active pokes in the heroin-addicted group increased, while the active pokes decreased significantly in 2Hz EA group compared with heroin-addicted group. Correspondingly, the expression of CB1-Rs in prefrontal cortex (PFC), hippocampus (Hip), nucleus accumbens (NAc) and ventral tegmental area (VTA) all increased significantly while the expression of CB2-Rs in those relapse-relevant brain regions decreased obviously in heroin-addicted group when compared with the control group. In addition, the expression of CB1-Rs obviously decreased in the 2Hz EA group while the expression of CB2-Rs in those relapserelevant brain regions increased significantly when compared with the heroin-addicted group. It indicated that 2Hz EA could attenuate the heroin-evoked seeking behaviors effectively. The anti-relapse effects of 2Hz EA might be related to the decrease of CB1-Rs and increase of CB2-Rs expression in relapse-relevant brain regions of heroin SA rats.
