- Description:
- Metody iontového zobrazování a zobrazování rychlostních map (velocity map imaging - VMI) se používají v nejrůznějších oblastech molekulové fyziky a dynamiky. Zaměřili jsme se zejména na studium fotodisociace molekul. V článku přehledně vysvětlíme princip zobrazovacích metod a představíme některé základní experimentální uspořádání a různé metody zpracování snímků. Také je nastíněna metoda detekce pomocí rezonanční ionizace částic umožňující rozlišení kvantových stavů. Na závěr uvedeme jeden příklad studia disociace molekul halogenvodíků na ledových nanočásticích v naší laboratoři a vysvětlíme, jak studované procesy souvisejí s tvorbou ozonové díry., Ion imaging and velocity map imaging (VMI) methods are currently applied in various areas of molecular physics. Here we focus on molecular photodissociation dynamic investigations. The basic principles of VMI methods are explained and essential experimental arragements are introduced as well as various image analyses methods. Resonance ionization methods enabling quantum state resolved detection are also briefly mentioned. Finally, an example from our laboratory is discussed, where hydrogen halide molecules are dissociated onto ice nanoparticles. Such processes are highly relevant for ozone hole generation in the stratosphere above Antarctic., Kateřina Grygoryeva, Viktoriya Poterya, Michal Fárník., and Obsahuje bibliografii

- Description:
- The paper deals with powerlessness as one of the possible meanings of alienation, and presents Neal’s Powerlessness Scale as a means for measuring this concept. The aim of this research is to find out if it is possible to adopt the Neal’s research technique, developed in the context of the American culture in the late 1950s, to empirical sociological research in the Czech Republic. This issue is important because there is at present no standard attitudinal instrument for measuring a persons’ perception of their power to exert influence over socio-political events. An initial test of the reliability and internal and external validity of Neal’s scale is undertaken using a non-representative sample of the Czech population. Results of this quantitative analysis suggest that a subset of nine items from the original twelve item scale is the most reliable and valid measure of a person’s sense of control over the socio-political events within the Czech cultural milieu. Importantly, the process of data collection reveals several problematic features of Neal’s powerlessness scale, and it is recommended that certain alterations before its further use in the Czech context., Marie Traxlerová, Ladislav Rabušic., 4 tabulky, Obsahuje bibliografii, and Anglické resumé

- Description:
- This study has two key aims. First, it explores the two main methods used in the Czech Republic to operationalize the concept of party identification. Second this study demonstrates the merits of both methods; and on the basis of this research proposes one of these party identification measures for use in future studies. This study builds on the classical conceptualization of party identification developed by the Michigan School, but also utilizes (1) reformulations proposed by the Revisionist School; (2) Macropartisanship theory; (3) the Social Identity approach; and (4) experience of using the party identification measure in Europe. Using the Czech Election Study of 2002 this research shows that estimates of partisanship are influenced by how the survey question is formulated. Thereafter, the relationship between the two main variants used in the Czech Republic is presented. This work reveals that use of a (prior) vote intention item leads to an ‘over estimation’ of partisanship when compared to the other partisan measure. Comparing estimates from the Czech Election Studies of 1996, 2002 and 2006 this article reveals that there is no simple association between party identification and voter turnout. In fact, it is better to think of party identification as having two components: (a) probability to vote; and (b) probability to support a party that elicits a sense of identity from voters., Lukáš Linek., and Obsahuje bibliografii a bibliografické odkazy

- Description:
- Results of research by scientists from the Institute of Molecular Genetics of the ASCR have been published on the U.S. National Library of Medicine website. Their work on the STIM1-directed reorganization of microtubules in activated mast cells could help in fighting allergies. The study reports that activation of bone marrow-derived mast cells (BMMCs) induced by FcεRI aggregation or treatment with pervanadate or thapsigargin results in the generation of protrusions containing microtubules (microtubule protrusions). In the study, formation of these protrusions depended on the influx of extracellular Ca(2+). Changes in cytosolic Ca(2+) concentration also affected microtubule plus-end dynamics detected by microtubule plus-end tracking protein EB1. Experiments with knockdown or reexpression of STIM1, the key regulator of SOCE, confirmed the important role of STIM1 in the formation of microtubule protrusions. Although STIM1 in activated cells formed puncta associated with microtubules in protrusions, relocastion of STIM1 to a close proximity of cell membrane was independent of growing microtubules. In accordance with the inhibition of Ag-induced Ca(2+) response and decreased formation of microtubule protrusions in BMMCs with reduced STIM1, the cells also exhibited impaired chemotactic response to Ag. Institute geneticists proposed that rearrangement of microtubules in activated mast cells depends on STIM1-induced SOCE, and that Ca(2+) plays an important role in the formation of microtubule protrusions in BMMCs. and Petr Dráber a Pavel Dráber.

- Language:
- Czech and English
- Description:
- Pro dyslipidemii u pacientů s metabolickým syndromem je typické zvýšení triacylglycerolů, snížení HDL-cholesterolu a přítomnost malých aterogenních částic LDL; většina pacientů však nedosahuje ani cílových hodnot LDL-cholesterolu pro svoji kategorii rizika. Základní součástí léčby má být přístup nefarmakologický – snaha o změny životního stylu (redukce hmotnosti, změna stravovacích návyků, zvýšení fyzické aktivity). U osob v primární prevenci bez diabetu rozhoduje o nasazení farmakoterapie výše rizika fatální kardiovaskulární příhody ve výhledu 10 let (tabulky SCORE). U diabetiků a u pacientů v sekundární prevenci indikujeme farmakoterapii tehdy, není-li jejich LDL-cholesterol v cílových hodnotách. Primárním cílem léčby je LDL-cholesterol, farmakoterapii proto zahajujeme statiny. Pokud po dosažení cílového LDL-cholesterolu přetrvává hypertriglyceridemie nebo nízký HDL-cholesterol, je vhodné přidat ke statinu fenofibrát., Typical feature of dyslipidemia in patients with metabolic syndrome is increase triglycerides, decrease HDL-cholesterol and prezence of small atherogenic LDL particle; nevertheless majority of patients do not reach target level of LDL-cholesterol for their risk category as well. An essential part of treatment should be non-pharmacological approach – lifestyle changes (weight loss, change in eating habits, increased physical activity). In patients in primary prevention without diabetes decision about pharmacotherapy depend on their risk of fatal cardiovascular events in the perspective of 10 years (table SCORE). In diabetic patients and in patients in secondary prevention is pharmacotherapy indicated, unless their LDL-cholesterol does not reach its target values. The primary goal of treatment is LDL-cholesterol, so pharmacotherapy should be started with statins. If the target of LDL-cholesterol is reached and hypertriglyceridemia and/or low HDL-cholesterol persist, it is recommended to add fenofibrate to statin., and Vladimír Soška
