Andrea Exnerová Enterobius vermicularis Bachelor thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Medical laboratory technician Background: The aim of this thesis is to create an overview of the current knowledge about Enterobius vermicularis and to perform a questionnaire study among parents. The aim of this survey is to find out informations about the progress, diagnosis and treatment of this infection and public awareness of this disease. Methods: Questionnaire study among parents, whose children have ever been infected with Enterobius vermicularis. Results: Pinworm infection is the most common among children aged 4-7 years. Half of the children who visited a pediatrician were examined. In almost 25 % of the cases, the stool sample was collected. The children were treated mostly with prescribed medication, the parents rarely chose home-treatment. In one third of the cases, the other members of the household were infected too. In the half of the cases the whole family was treated preventively. The most common symptom is rectal itching (83 %). Complications are exceptional. 60 % of the respondents incorrectly think that it is possible to get infected with pinworms from animals. The respondents most commonly called enterobiasis a disease of dirty hands. Conclusions: The...

Filipová, Petra ; Němečková, Ivana (advisor) ; Doleželová, Eva (referee)
Charles University in Prague, Faculty od Pharmacy in Hradec Králové Department of Biological and Medical Sciences Progression of endothelial dysfunction in heart in a mouse model of atherosclerosis Author of diploma thesis: Petra Filipová Supervisor: RNDr. Ivana Němečková, Ph.D. Backround: Atherosclerosis is a disease when atherosclerotic lesions are formed in vessels. It represents the major cause of the heart failure and stroke. The endothelial dysfunction, which has been recorded in a large number of animals, is considered one of the main causes of atherosclerosis. In our work we have focused on the detection of the endothelial dysfunction markers in the heart of the ApoE/LDLR double knock-out mouse model. Methods: We detected changes in the expression of eNOS, p-eNOS and HO-1 in two-months and eight-months old ApoE/LDLR double knock-out mice, which were fed standard chow diet. For the semiquantitative evaluation of the observed markers we used the Western blot analysis of the homogenated left ventricle. Results: According to our results there is no difference in the expression of eNOS, p-eNOS and HO-1 in the studied mouse model of atherosclerosis in relation to age. This might mean, that the endothelial dysfunction in the coronary vessels of these mice doesn't develop. However, for further...

Kosán, Aleš ; Němečková, Ivana (advisor) ; Doleželová, Eva (referee)
C-REACTIVE PROTEIN EFFECTS ON AORTIC ENDOTHELIUM IN SPONTANEOUSLY HYPERTENSIVE RATS Diploma thesis Author: Aleš Kosán Study program: Pharmacy Charles University in Prague Faculty of Pharmacy in Hradec Králové Endothelial dysfunction and chronic inflammation are factors figuring in pathogenesis of metabolic syndrome. This paper is outlined as a pilot study, which represents basis for further research in the question of C-reactive protein influence on endothelium. The expression of four proteins previously associated with the development of endothelial dysfunction, was studied using the Western blot method: endothelin-1, heme oxygenase-1, endoglin and phosphorylated nitric oxide synthase. Analysis was carried out on the samples of homogenized rat aortas of transgenic spontaneously hypertensive rats with expression of human C-reactive protein. A standard spontaneously hypertensive rat strain was used as a control group. The detection was made by chemiluminescence substrate on the X-ray films and data were semiquantitatively evaluated by densitometry. We found increased expression in endoglin levels, valued at 186.3 % contrary to the control group. The expression of phosphorylated nitric oxide synthase was 325.6 % in comparison with the control group. The increase of expression was minimal (109.0 %) in...

Interactions between WLAN networks
Doleželová, Eva ; Zeman, Kryštof (referee) ; Škorpil, Vladislav (advisor)
This bachelor thesis deals with the possible interferences caused by the parallel running WLAN networks. It explains the history and subsequent development of wireless technologies and then focuses on current WLAN networks. It describes the problem of interference in WLAN networks and parameters that contribute to mutual interference. Practical part of this thesis consists of two laboratory exercises. The first task is implemented in the Riverbed program, in which a topology with three identical WLAN routers is assembled. After testing the WLAN routers, a graph describing the interference in the 2.4 GHz band is displayed, which is achieved by a suitable choice of frequency band, transmission power and channel. The second laboratory task is implemented utilizing the Iperf3 program, which is installed on three Raspberry Pi´s (RPi Zero, RPi 3, and RPi 4). Network congestion is achieved using the wifijammer script, which is installed on RPi 4. In this second laboratory task, the transmission parameters were first verified and the service was denied using the wifijammer script. For evaluation of the second laboratory task, the IEEE 802.11b and IEEE 802.11n utilizing the frequency band 2,4 GHz were chosen. For testing, the following routers were used: Mercusys, Netis, Tp-Link and Asus routers. Once the measurements were over, all the data was processed and included as charts.

Genetic diseases of the liver
Šepsová, Marika ; Doleželová, Eva (advisor) ; Tripská, Katarína (referee)
Author: Marika Šepsová Title: Genetic diseases of the liver Form: Bachelor Thesis University: Charles University, Faculty of Pharmacy in Hradec Králové Degree: Medical Laboratory Technician Liver function may be affected by various factors including genetic diseases. The aim of this bachelor thesis is to collect and summarize current information about genetic diseases of the liver. Diseases with the highest incidence in the population are Dubin-Johnson syndrome, Rotor syndrome, Crigler-Najjar syndrome and Gilbert's syndrome. They are known as inherited hyperbilirubinemia characterized by an impairment in bilirubin metabolism. These genetic diseases are very rare with exception of Gilbert's syndrome. However, despite low prevalence and incidence it is necessary not to prolong their diagnosis. Most of them do not have any complications and do not require any treatment. The exception is Crigler-Najjar's syndrome, as untreated can have fatal consequences. Wilson's disease and hereditary hemochromatosis are inherited disorders of metal metabolism. Wilson's disease is a rare disease caused by an impairment in copper metabolism. Inherited hemochromatosis causes excessive iron deposition in the liver and other organs. Alpha-1 antitrypsin deficiency is characterized by impaired alpha-1 antitrypsin protein...

Author: Nikola Jozefčeková Title: Endoglin and liver Form: Diploma Thesis University: Charles University, Faculty of Pharmacy in Hradec Králové Degree: Pharmacy This diploma thesis concludes the available information about endoglin, its isoforms in the liver and its impact on the liver during various pathological conditions. In the first part of the thesis describes morphology and physiology of the liver, its structure, histology and metabolic functions. Second part contains an information about endoglin, its isoforms and role in TGF-β signaling complex, expression of endoglin and regulation of the expression. In the third part are described liver diseases during which is expression of endoglin changed. This part deals with the significance of endoglin as a diagnostic and prognostic marker. Endoglin (CD105, TGF-β receptor III) is a homodimeric transmembrane glycoprotein and a membrane co-receptor TGF-β with high expression in endothelial cells. Endoglin plays an important role in the vascular development. Endoglin is involved in the processes of angiogenesis, vascular homeostasis and TGF-β signalization. It affects activity of TGF-βRII, ALK1 and ALK5 receptors. Due to the interactions with TGF-β complex, modulation of activity of ALK receptors and Smads, endoglin controls fibrotic and anti-...
