Patogeneze eczema vaccinatum / Pathogenesis of eczema vaccinatumElsterová, Jana January 2012 (has links)
Vaccinia virus (VACV) is primarily known as a vaccine against its relative variola virus, the causative agent of smallpox. In the seventies of the 20th century, the vaccination campaign with VACV led to eradication of smallpox. Consequently, vaccination of the general population was stopped. Currently, the vaccination was reintroduced, namely among army and healthcare professionals. However, vaccination with VACV is accompanied with a high incidence of vaccination-related complications, namely among immunocompromised individuals. One of the complications is eczema vaccinatum, occuring in patients with atopic dermatitis. The laboratory of Dr. Melkova has focused on development of a model of eczema vaccinatum in mice Nc/Nga and on studies of pathogenesis of this complication. The goal of my diploma thesis is to contribute to characterization of imunopathogenesis of eczema vaccinatum in mice Nc/Nga infected either with VACV strain Western Reserve (WR) or with a recombinant VACV with the integrated cDNA for IRF-3 (Interferon Regulatory Factor 3; WR-IRF3). IRF-3 regulates the expression of interferon type I in response to viral infection. This recombinant virus has been constructed in the laboratory of Dr. Melková. The objective of my work was to verify the expression of the integrated cDNA for IRF-3 and to...

Fenomén non-compliance pacientů s diagnózou L2x: atopická dermatitida / The Non-Compliance Phenomenon and the Diagnosis of L2x: Atopic DermatitisHlavatá, Jana January 2013 (has links)
The aim of this thesis is to analyze the prevalence of the phenomenon of non-compliance patiens with a diagnosis of atopic dermatitis using the questionnaire survey in two selected dermatology clinics in Prague. The result obtained were tested using standard statistics methods. The results suggest the non-compliance depends mainly on attitude of physisians.

Studium regulačních vlastností onkogenních mikroRNA za normálních a patologicky změněných podmínek s cílem využít znalosti k odhalení nových tumorů. / Study of the regulatory properties of oncogenic microRNAs under normal and pathologically altered conditions in order to detect new tumors.Dusílková, Nina Borisovna January 2021 (has links)
Oncogenic microRNAs (miRNAs) are small RNA molecules that inhibit post-translational regulatory mechanisms at the epigenetic level. miRNAs are often deregulated in malignancies and due to their stability are detectable in non-cellular fractions of peripheral blood. In our laboratory, we have performed several studies that have investigated and utilized miRNAs as biomarkers for various hematological tumors (e.g., chronic lymphocytic leukemia, Hodgkin`s lymphoma) and solid tumors (e.g., breast cancer). The aim of these studies was to find the association of miRNAs with pathophysiological and clinical aspects of each disease. Here, we confirmed the importance of particular miRNA or its complex during disease monitoring. Combining clinical, molecular biological and statistical analyses, we were able to find miRNA sets that fulfilled not only a diagnostic role but also a prognostic role beyond expectations. The main focus of this thesis is on the investigation of microRNAs in the diagnosis of a hematological malignancy - primary cutaneous T-cell lymphoma (CTCL). Tumor specificity of some miRNAs has been demonstrated. Their aberrant expression in tissue samples of CTCL patients obtained from skin biopsies, correctly distinguished malignant disease from control samples of benign skin lesions. Here, we...
