Parasitic organisms inhabiting the alimentary canal should permanently resist the destructive action of host digestive enzymes. The intestinal parasites were shown to produce specific protease inhibitors protecting them from proteolysis. However, little is known about this adaptive mechanism in cestodes so far, especially for the tapeworms dwelling inside the fish intestines. Here, we explored the ability to inactivate proteolytic enzymes in the fish tapeworm Eubothrium rugosum (Batsch, 1786) (Bothriocephalidea) parasitising the intestine of wild burbot, Lota lota (Linnaeus). The assays were conducted with different concentrations of commercial trypsin and homogenate of intestinal mucosa both being the sources of proteinases. The incubation of live E. rugosum in trypsin solutions of two different concentrations caused a significant decrease in the enzyme activity. The extent of activity reduction was dependent on trypsin concentration. At the same time, the inhibitory effect of the worm incubation medium turned out to be statistically insignificant. These findings suggest partial adsorption of the enzyme to the tegument surface, with its further inactivation. In contrast to the incubation medium, the worm extract suppressed over 80% of trypsin activity and nearly half of the proteolytic activity in the mucosa homogenate. Notably, the inhibitory activity of the tapeworms hardly depended on their size characteristics. Finally, the research has demonstrated secretion of proteinase inhibitor in E. rugosum, which appears to be essential for its survival in enzymatically hostile environment., Galina I.

CEFRES Platform and its new premises within the Czech Academy of Sciences were inaugurated on October 7-8, 2015. In 2015, theCAS built a brand newlibrary in order to hostCEFRES’smore than 6,000 volumes alongwith its teamand Prague’s Francophone readers. The new library was inaugurated during a ceremony in the presence of French Ambassador Jean-Pierre Asvazadourian, President of CAS Jiří Drahoš and Rector of Charles University Tomáš Zima. CEFRES (French Research Center in Humanities and Social Sciences) was founded in Prague in 1991 with the aim to restart scientific exchanges between France and Central Europe as the latter underwent major changes after the fall of communism. One of CEFRES’s tasks since then has been to build up a network of research teams between France, the Czech Republic, Hungary, Poland and Slovakia. and Luděk Svoboda.
Úvod: Informace o prevalenci orgánových komplikací diabetu včetně syndromu diabetické nohy v České republice je možné získat z dokumentů Ústavu zdravotnických informací a statistiky. Cíl: Posoudit vývoj vysokých amputací a drobných výkonů na noze v letech 2010–2014 v reprezentativním vzorku populace pacientů s diabetes mellitus vedených v databázi Všeobecné zdravotní pojišťovny (VZP) České republiky. Metodika: V databázi VZP jsme identifikovali všechny osoby, které měly v letech 2010–2014 záznam o diagnóze DM (E10–E16 podle MKN 10) nebo předpis jakékoliv antidiabetické terapie (ATC skupina A10). Pro analýzu byl extrahován soubor osob, které měly v daném roce předepsanou nejméně jednou látku ze skupiny A10. Následně jsme identifikovali osoby, které v letech 2010–2014 současně prodělaly chirurgický výkon na noze z důvodu diagnózy diabetické nohy. Výsledky: Absolutní počet amputačních výkonů na končetině vykazuje stacionární úroveň. Závěr: Předkládaná analýza je prvním zhodnocením vývoje výkonů na diabetické noze v ČR. Je zřetelný setrvalý stav v počtu výkonů na diabetické noze, a to jak vysokých amputací, tak drobných výkonů na noze. V kontextu s absolutním nárůstem pacientů, léčených pro diabetes mellitus, je stacionární stav známkou relativního poklesu, což je příznivé především v oblasti amputace dlouhých kostí. Klíčová slova: amputace – diabetes mellitus – syndrom diabetické nohy, Introduction: Information about the incidence of organ-affecting complications of diabetes, including the diabetic foot syndrome, can be obtained from the documents of the Institute of Health Information in the Czech Republic. Goal: Assessment of the development of high amputations and minor surgical procedures on the lower limb from 2010 to 2014 in a representative sample of the population of patients with DM kept in the General Health Insurance Company of the Czech Republic database. Methodology: We identified all individuals in the VZP database who had a record of DM diagnosis (E10 – E16 based on ICD 10) or any antidiabetic therapy prescribed (ATC group A10) in the period of 2010 – 2014. A set of patients who had an agent from A10 group prescribed at least once in the given year was extracted for analysis. In the next step we identified individuals, who in the period of 2010 – 2014 also underwent a surgical procedure on the lower limb due to diabetic foot. Results: An absolute number of lower limb amputations remains at a stationary level. Conclusion: The submitted analysis presents the first assessment of the development of surgical treatment of diabetic foot in the Czech Republic. The amount of surgical procedures on the diabetic foot remains stable, regarding both high amputations and lower limb minor surgical procedures. In the context of an absolute increase of patients treated for diabetes mellitus, the stationary state is an indication of a relative decrease, which is favourable in particular with regard to the amputation of long bones. Key words: diabetes mellitus – diabetic foot syndrome – amputation, and Pavlína Piťhová, Petr Honěk, Ladislav Dušek, Tomáš Pavlík, Milan Kvapil
Jako incidentalom se označuje náhodně zjištěná expanze nadledviny. Vzhledem k rozvoji zobrazovacích technik se s ní setkáváme stále častěji. Její prevalence je totiž více než 1 % dospělých a roste s věkem. Při vyšetření je nutno vyloučit malignitu. K tomu slouží klasicky vyšetření CT, ev. MRI. Nověji se stále více uplatňuje PET-CT, která má senzitivitu asi 97 % a specificitu 91 %. Hormonální vyšetření má vyloučit i subklinickou nadprodukci kortizolu (optimální je dexametazonový supresní test). Aldosteron je nutno vyšetřovat jen u nemocných s hypertenzí a katecholaminy u nádorů s vyšší nativní denzitou než 10 HU. Při sledování je nutnost opakovaných CT vyhrazena jen pro vybrané případy a rutinní kontrolní laboratorní vyšetření jsou také zpochybněna., Incidentaloma is an adrenal mass discovered serendipitously. Because of increasing use of imaging techniques it is a common finding, being present in more than 1 % of adults. During work-up malignancy has to be ruled out. Classically imaging using CT or MRI is used. Recently PET-CT with FDG has been used more often as its sensitivity for diagnosis of malignancy is about 97 % and specificity 91 %. Hormonal evaluation should diagnose subclinical hypercortisolism. (Dexamethasone Suppression Test is the method of choice). Aldosterone and Renin should be measured only in patients with hypertension and catecholamines in tumours with higher native density than 10 HU. During follow-up repeated CT scan are needed only in selected patients and the need of routine biochemical follow-up has been questioned as well., and Jan Čáp, Filip Gabalec

The presence of a broad spectrum of autoantibodies in Sjögren's syndrome (SjS) patients is the result of abnormal B-cell regulation that can be at least partially explained by abnormal BAFF/BAFFR regulation. The objective of this study was to determine both membrane and intracellular expression of BAFF/BAFFR in monocytes and B-cells in peripheral blood of 19 primary Sjögren's syndrome patients and 20 healthy controls using flow cytometry. We also measured sBAFF in serum. Compared to healthy controls, both surface and intracellular expression of BAFF was significantly increased in monocytes and B-cells of SjS patients. Also serum sBAFF level was elevated. Expression of BAFFR on B-cells of SjS patients was surprisingly decreased, but there was no clear increase or decrease within monocytes. Our results indicate that activated monocytes communicate with B-cells via BAFF and BAFFR, so that B-cells are stimulated, but BAFF is also produced to stimulate cells in autocrine way. The decrease of BAFFR expression in SjS patients suggests that there is the mechanism that attempts to take over in order to balance the high level of BAFF. and J. Krejsek, M. Koláčková, I.

In hemodialyzed patients hormonal disturbances are known to occur. However, melatonin levels have not been completely studied. The aim of the study was to find whether changes in calcaemia affect melatonin secretion. For this reason we followed the nocturnal serum concentrations of melatonin and parathyroid hormone (PTH) in 9 hemodialyzed patients (6 women and 3 men, aged 37-65 years) both before and 1-3 months after parathyroidectomy at 6 p.m., 9 p.m., 11 p.m., 2 a.m., 5 a.m. and 7 a.m. At 6 p.m. blood samples to evaluate the levels of calcium and phosphate were also collected. Parathyroidectomy resulted in an increase in nocturnal melatonin levels. As expected, the parathyroidectomy was followed by considerable PTH decrease. PTH showed no nocturnal variation before or after parathyroidectomy. Calcium levels significantly decreased after the operation while phosphate levels increased. In summary, in hemodialyzed patients with hyperparathyroidism, parathyroidectomy significantly increases the nocturnal secretion of melatonin. Relationships between the pineal gland and parathyroid glands have yet to be elucidated., R. Kancheva, S. Sulková, F. Švára, M. Hill, L. Kanchev, I.
