Toxoplasma gondii (Nicolle et Manceaux, 1908) is an obligate intracellular apicomplexan parasite and can infect warmblooded animals and humans all over the world. Development of effective vaccines is considered the only ideal way to control infection with T. gondii. However, only one live vaccine is commercially available for use in sheep and goats. Thus more effective antigenic proteins are searched for. In the present study we report a novel protein by secreted T. gondii termed Myc regulation 1 (MYR1). The physical and chemical characteristics, epitopes, hydrophilicity and functional sites of MYR1 were analysed by multiple bioinformatic approaches. The 3D models of MYR1 proteins were constructed and analysed. Furthermore, liner B-cell epitopes and T-cell epitopes of MYR1 protein and SAG1 were predicted. Compared to SAG1, MYR1 with good B-cell epitopes and T-cell epitopes had a potentiality to become a more successful vaccine against T. gondii. The bioinformatics analysis of MYR1 proteins could laid the foundation for further studies of its biological function experimentally and provide valuable information necessary for a better prevention and treatment of toxoplasmosis., Jian Zhou, Gang Lu, Shenyi He., and Obsahuje bibliografii
High temperature alters the internal microstructure of rocks and consequently changes the physical and mechanical properties of rocks. Many studies have been carried out to examine the transformations in the microstructures of rocks under high temperature through near infrared spectroscopy (NIR), Raman spectroscopy, or thermo gravimetric analysis (TGA). The current review synthesizes the data from a number of literatures and summarizes the major transformations of silica rocks under high temperature. The analysis shows that silica rocks starts to lose the water adsorbed in open pores upon heating at about 150 °C. At 200-300 °C, the reaction between SiOH (silanole) in the rocks generates new Si-O-Si bonds as well as H2O, and decreases the open pores. The rocks undergo volume expansion at >550 °C, and the volume contracts and forms new micro pores or cracks which play an important role in the evacuation of the water., Jishi Geng, Qiang Sun, Yuchun Zhang and Yuliang Zhang., and Obsahuje bibliografické odkazy
Úvod: Výsledky poskytované chirurgické péče v širším přesahu jsou obtížně dosažitelné. Práce testovala systém účtování zdravotní pojišťovně z hlediska využitelnosti dat. Metoda: Analyzováno bylo 6879 operací tříselné kýly v období 2008–2015. Využit byl systém účtování v DRG Vojenské zdravotní pojišťovny České republiky. Výsledky: Operace provedlo 156 pracovišť. V režimu jednodenní chirurgie bylo provedeno 3,8 % (248) výkonů, z toho 77 % (193) bylo operováno laparoskopicky. Za hospitalizace bylo provedeno 96,2 % (6631) výkonů, medián délky hospitalizace byl 4 dny. U hospitalizovaných pacientů byla otevřená plastika bez síťky provedena v 36,54 % (2423), otevřená plastika se síťkou v 19,84 % (1316), laparoskopická plastika v 43,61 % (2892). Reoperace pro recidivu v souboru byla v 1,85 % (127), po otevřené plastice bez síťky v 2,76 % (66), po otevřené plastice se síťkou v 1,66 % (22), po laparoskopické plastice v 1,19 % (37). Predikce recidiv do 5 let byla 2,42 % celkem. Hodnoceny byly i další parametry. Závěr: Studie potvrdila využitelnost systému pojištění k získání relevantních dat o léčbě vybrané diagnózy., Introduction: Information about actual results of provided surgical care is difficult to obtain. We tested the insurance company billing system in terms of data usability. Methods: 6,879 groin hernia surgeries carried out from 2008 to 2015 were analysed using registry data of one health insurance company. Results: Groin hernia surgeries were performed by 156 providers in the Czech Republic. Day surgeries were used in 3.8% cases (248), of which laparoscopic surgeries were used in 77% (193) of patients. The other 96.2% (6,631) surgeries were carried out on inpatients with the median hospital stay of 4 days. Of this number: open procedures without the use of a mesh were done in 36.54% (2,423), open procedures using a mesh in 19.84% (1,316), and laparoscopic procedures in 43.61% (2,892) cases. Reoperations for recurrence after hernia repair were done in 1.85% (127) of all cases, while 2.76% (66) reoperations were done after open procedures without the use of a mesh, 1.66% (22) after open procedures using a mesh, and 1.19% (37) after laparoscopic surgeries. The prediction rate for recurrent hernia incidence within 5 years was 2.42% in all cases. Others parameters were also evaluated. Conclusion: The study confirmed usefulness of the DRG data registry of health insurance companies for obtaining relevant information on the surgical procedures., and P. Chmátal, L. Tuka, D. Jandová
