Determination of tumor mRNA in colorectal cancer as screening and forecasting methods
Rupert, Karel ; Holubec, Luboš (advisor) ; Hoch, Jiří (referee) ; Pešková, Marie (referee) ; Dostalík, Jan (referee)
The level of MMP-7, TIMP-1 and MMP-2 mRNA expression was significantly higher in the tumour tissue of colorectal carcinoma than in normal colorectal tissue. It could be possible to inhibit matrix metalloproteinases activity using appropriate antibodies, which could have therapeutic effect on tumour tissue and its vicinity. Some of the preparations are being tested (Bay 12-9566 /Bayer/, BB94 /British Biotechnology/). We have not proved correlation between expression of these genes and disease stage and diagnosis. We have succeeded to prove that if the surgical principles for colon resection performed due to colorectal carcinoma are observed, the resection line does not show any signs of the presence of tumour cells - mRNA for CEA is not present. The level of mRNA for TIMP-1 is present in the resection line at lower levels than in tumour tissue, and this is due to the role that TIMP- 1 plays in the colon. Its level increases not only in all tumour diseases, but also in inflammatory diseases of the colon. The question whether the expression of mRNA for TIMP-1 is also increased outside the resection line and therefore it is a reaction of the colon as an organ will be subject to further research, as will be a potential comparison with samples of colon unaffected by tumour or inflammation. Although the...

Freight in Alps and Switzerland
Vonásek, Martin ; Zelený, Lubomír (advisor) ; Pešková, Marie (referee)
The paper deals with extarnalities in transport, position of Switzerland in european freight and situation in alpine freight in overall. Analyzes instruments applied in the swiss Road to rail transfer politics, infrastructure charging, rail infrastructure projects and development of freight in swiss alpine tunnels since 1980. The paper briefly discuses possible solitions with overlap into future of swiss trafic management projects.
