Článek má dvě části. V první části se pokouší podat širší přehled o empirickém sociologickém výzkumu v České republice na základě dostupných dat z databází vědy a výzkumu. V textu jsou pak uvedeny hlavní producenti empirických výzkumů v ČR a také tematické zaměření těchto výzkumů. V druhé části článku je popsán přístup k již dostupným datovým zdrojům, zejména k těm souborům, které jsou uloženy v Sociologickém datovém archivu. Jsou také popsána významná mezinárodní šetření, která proběhla na území ČR a přístup k datovým souborům vzniklých v jejich rámci., The text has two parts. The first part attempts to give a broader overview of empirical sociological research in the Czech Republic on the basis of available data from project databases. The main producers of empirical research in the Czech Republic and the thematic focus of this research are then analyzed. In the second part of the article the access to the already available data sources is described, especially to those data files that are stored in the Sociological Data Archive. Important international surveys, which took place also in the Czech Republic and access to data files from this projects is then presented., and Tomáš Čížek.
Pro vězení je na rozdíl od jiných institucí příznačné, že za svými zdmi shromažduje chovance nedobrovolně. Veškerý čas a aktivity vězňů jsou striktně strukturovány. Autoritě instituce, která za své svěřence přebírá zodpovědnost a tím pádem i možnost sankcionovat nežádoucí chování, jsou podřízeny veškeré aspekty života (některé aspekty, jako je např. rodinný život, jsou pak ze života v lůně totální instituce zcela vyňaty). Odsouzený má pouze omezený manévrovací prostor pro prosazení svých zájmů. Navíc vězení představuje značnou zátěž nejen pro odsouzené, ale klade vysoké nároky také na vězeňský personál, jenž má za úkol starat se o izolaci a převýchovu vězňů., The article concern on the prison system. In the first part are described attitudes of public opinion towards crime and prison system. Not only in the terms of causes of criminal behavior. It also brings an evaluation of particular conditions and facilities which are available or which would be hypothetically available for prisoners in contemporary Czech prison system. The second part brings information about prison from prisoners point of view. It sums up the particular needs and problems resulting from imprisonment. And the third part comes with a c omparison of prisoners and public opinion attitudes on some moral dilemmas of chosen kinds of human behavior., and Michal Veselský.
Článek shrnuje současné názory na vnitrodruhové genetické rozrůznění a taxonomii zmije obecné (Vipera berus). Zvláštní pozornost je věnována genetické příslušnosti populací českých zmijí., This article summarizes contemporary knowledge of the intraspecific genetic differentiation and taxonomy of the Common Adder (Vipera berus). Special attention is paid to the genetic status of the Czech adders., and Jiří Moravec, Jiří Šmíd.
Perloočky rodu Daphnia jsou intenzivně studovaní vodní bezobratlí. Proto byl pro nás velkým překvapením objev pro vědu nového druhu tohoto rodu v tůni na Kokořínsku. Druh byl pojmenován po významném českém hydrobiologovi Jaroslavu Hrbáčkovi, ale jeho jméno odkazuje i na hrbatý tvar těla. Jeho doposud známé lokality jsou pouze v Čechách a na Slovensku., Species of water fleas that belong to the genus Daphnia have been used intensively in studies as “model organisms”. The discovery of a new Daphnia species in a pool in Central Bohemia was, therefore, a surprise. All known localities of this species, which we named after the prominent Czech hydrobiologist Jaroslav Hrbáček, are restricted to Czechia and Slovakia., and Adam Petrusek, Petr Jan Juračka.
Quantitative and qualitative changes of serum proteins, apart from glycation, have not been sufficiently studied in streptozotocin-induced diabetic rats (D), the most common experimental model for diabetes. Thus, we decided to analyze the serum of diabetic rats by concanavalin A-blotting in comparison with rats with acute inflammation induced by fermented yeast (Y), in which characteristic alterations of serum proteins have been described. Two months after the streptozotocin treatment, the blood glucose levels were highly elevated (456± 24 vs. 124± 10 mg/dl, p<0.001, n=12), the body weight was significantly lower than normal (279± 10 vs. 392± 6 g, p<0.001, n=12), and serum proteins appeared to be highly glycated (p<0.001) when analyzed by the fructosamine assay, without any significant change in the total serum protein concentration. Analysis by concanavalin A-blotting, revealed a significant decrease of a1-inhibitor-3 (a1-I3, p<0.05) and an increase of the b chain of haptoglobin (b-Hp, p<0.05) in both D and Y rats (n=3) compared with control animals. However, acute inflammation caused a marked rise of two prominent acute phase proteins, a2-macroglobulin and hemopexin, which did not change appreciably in diabetic rats. Further work will be necessary to evaluate the physiopathological significance of these phenomena which could result from changes of both concentration and glycosylation of the aforementioned proteins., L.

Smoking during pregnancy presents health risks for both the mother and her child. In this study we followed changes in the production of steroid hormones in pregnant smokers. We focused on changes in steroidogenesis in the blood of mothers in their 37th week of pregnancy and in mixed cord blood from their newborns. The study included 88 healthy women with physiological pregnancies (17 active smokers and 71 nonsmokers). We separately analyzed hormonal changes associated with smoking according to the sex of newborns. In women with male fetuses, we found higher levels of serum cortisone, dehydroepiandrosterone (DHEA), 7α-OH-DHEA, 17-OH pregnenolone, testosterone, and androstenedione in smokers at the 37th week compared to non-smokers. In women with female fetuses, we found lower serum levels of 7β-OH-DHEA and higher androstenedione in smokers at the 37th week. We found significantly higher levels of testosterone in newborn males of smokers and higher levels of 7α-OH-DHEA in female newborns of smokers. Smoking during pregnancy induces changes in the production of steroids in both the mother and her child. These changes are different for different fetal sexes, with more pronounced changes in mothers carrying male newborns as well as in the newborn males themselves., K. Adamcová, L. Kolátorová, T.

Acute dilation brought about by the dietary flavonoid quercetin in coronary arterioles has been described earlier, but no information is available on its chronic effects. Male Wistar rats (body weight about 190 g) were divided to two groups: the quercetin-treated group (n=22) had quercetin supplementation of approximately 30 mg/kg/day, whereas the control group (n=20) had none. After eight weeks of treatment, intramural coronary arterioles with identical passive diameters (178±14 μm and 171±9 μm) were prepared and their biomechanics and pharmacological reactivities were tested using pressure arteriography ex vivo. The spontaneous tone of quercetin-treated arteries was higher (16.5±1.9 % vs. 12.9±0.9 %), which resulted in a reduced lumen size (144±9 μm vs. 167±12 μm), thicker vascular wall (22.6±1.8 μm vs. 17.4±1.6 μm) and decreased tangential wall stress (16.8±1.1 kPa vs. 20.5±1.6 kPa) in supplemented animals (in spontaneous tone at 50 mm Hg, p<0.01 in all these comparisons). Elevated basal NO release resulted in increased endothelial dilation in quercetin-treated animals, especially at higher intraluminal pressures (10.8±2.5 % vs. 5.7±1.3 % at 70 mm Hg, p<0.01). We found remodeling of the geometry of coronary arterioles to ensure higher dilatory reserve and nitrogen monoxide production, as well as lowered elastic stress of the vessel wall., A.
