Protilátkami zprostředkovaná rejekce po transplantaci ledviny / Antibody-mediated rejection after kidney transplantation

Slatinská, Janka January 2021 (has links)
Antibody-mediated rejection (AMR) is the main cause of the kidney graft dysfunction and its failure after transplantation. Antibodies lead to vascular damage that is either acute or chronic and manifests as sudden or progressive graft dysfunction. Risk factors for development of AMR are time spent on haemodialysis, retransplantation, previous sensitisation against HLA antigens, and persistence of panel-reactive antibodies. Diagnosis is based on detection of deposits of C4d component of complement in peritubular capilaries and presence of donor-specific antibodies (DSA). We can also observe injury caused by antibodies against non-HLA antigens without detection of anti-HLA DSA. Use of "molecular microscope" can be beneficial in diagnosis and stratification of the risk of graft failure. High expression of ENDAT (endothelial activation and injury transcript) improves prediction of kidney graft failure more than C4d staining. Based on gene expression, the AMR scoring system correlates with the diagnosis of AMR and predicts graft loss in the future. The main goal of our work was to recognize patients at risk of AMR. In our study, we confirmed the efficacy and safety of acute AMR therapy with plasmaphereses and administration of intravenous immunoglobulins for improving outcomes of kidney transplantation....

Příprava cvičení pro dolování znalostí z báze dat - klasifikace a predikce / Design of exercises for data mining - Classification and prediction

Martiník, Jan January 2009 (has links)
My master's thesis on the topic of "Design of exercises for data mining - Classification and prediction" deals with the most frequently used methods classification and prediction. There are association rules, Bayesian classification, genetic algorithms, the nearest method neighbor, neural network and decision trees on the classification. There are linear and non-linear prediction on the prediction. This work also contains a summary of detail the issue of decision trees and a detailed algorithm for creating the decision tree, including development of individual diagrams. The proposed algorithm for creating the decision tree is tested through two tests of data dowloaded from Internet. The results are mutually compared and described differences between the two implementations. The work is written in a way that would provide the reader with a notion of the individual methods and techniques for data mining, their advantages, disadvantages and some of the issues that directly relate to this topic.

Dolování dat / Data Mining

Stehno, David January 2013 (has links)
The aim of the thesis was to study and describe data mining methodology CRISP-DM. From the collected database of calls to the call center a prediction was performed, based on CRISP-DM methodology. In phase of test situation modeling four different testing methods were used: the k-NN, neural network, linear regression and super vector machine. The input attributes importance for further prediction was evaluated based on different selections. The results and findings may provide data for further more accurate forecasts in the future; not only in number of calls but also other indicators relevant to the call center.
