The study of signaling pathways that modulate multidrug resistance The theme of cancer cell resistance to anti-cancer drugs including the common mechanisms of resistance development and the theory of cancer stem cells was introduced in the Introduction to the doctoral thesis. The theoretical part was focused more deeply on the two topics - the role of ATP-binding cassette (ABC) transport proteins and chromosomal abnormalities in the development of cancer chemoresistance. The possible therapeutic potential for the treatment of cancer was stressed for both topics. The Results were composed of the commentaries on the five published works, which the author of the thesis conducted as the main author. The first work brought the evidence supporting the hypothesis of the existence of ABC gene expression profiles (signatures), which are common to multiple types of tumors and are associated with significant clinical consequences. These general ABC gene expression profiles could possibly form a new hallmark of cancer. The second work studied more closely a group of acute myeloid leukemia patients, who did not achieve complete cytogenetic remission after two attempts to maintain remission of the malignant disease. The new entity, consisting of patients with the translocation t(2;11)(p21;q23) without the...

Introduction: Metabolic syndrome and depression are considered to be important risk factors for the development of cardiovascular diseases. The prevalence of metabolic syndrome is estimated to be around 25% of the adult population in industrialized countries, including the population of Czech Republic. The prevalence of depression is estimated to be around 15% of the same adult population. It is not clear yet on the base of poor literature, which is so far available, whether there is a causal relationship between these factors or not. Objective: To try to find a relationship between metabolic syndrome and depression in a population sample using clinical and metabolic parameters. Methods: The prevalence of depressivity or other psychopathologies was evaluated with the use of self-report questionnaires in a randomly selected population sample of 259 people living in Pilsen. The questionnaires were mailed to the subjects. Those of them who responded were invited to the examination of anthropometric and laboratory parameters defining the metabolic syndrome and to the examination of some other parameters. The occurrence of risk factors of the metabolic syndrome of insulin resistance and the relationship between depression and metabolic syndrome was investigated. Metabolic syndrome of insulin resistance...

18 effects of TZDs are probably due to the remodeling of adipose tissue and increased adiponectin secretion. SUMMARY Studying the pathogenesis of insulin resistance and the role of PKC in insulin resistance In HHTg rats, elevated serum triglycerides and FFA were associated with the ectopic accumulation of triglycerides in tissues and reduced insulin sensitivity of peripheral tissues. Impaired glucose utilization in the peripheral tissues was associated with the reduced activity of GS in skeletal muscle. Decreased GS activity and glucose utilization in peripheral tissues indicate a possible defect in insulin signal transduction. In line with this, our results show that skeletal muscle IR was associated with the increased activation and translocation of PKC θ. Nutritionally induced obesity of HHTg rats resulted, in many cases, in the further deterioration of metabolic abnormalities associated with IR. We found that PKC θ, in particular, could contribute to the metabolic abnormalities associated with IR and obesity. The age-related increase in IR and deterioration of some parametres of carbohydrate and lipid metabolism, were not associated, in HHTg rats, with obesity but with increased serum levels of triglycerides and FFA. The age-related worsening of IR in HHTg rats was accompanied by increased...

DIABETES MELLITUS TYPE II IN THE LIGHT OF METABOLIC SYNDROME Author: Eliška Hrnčířová ¹ Tutor: MUDr. PharmDr. Kamil Rudolf, Ph.D. ¹, š ¹ Department of Clinical and Social Pharmacy, Charles University in Prague, Faculty of Pharmacy in Hradec Králové š II. intern gastroenterology clinic University Hospital Hradec Králové Background: My thesis deals with diabetes mellitus, a common chronic civilization disease, the essence of its creation, including the issue of the treatment, regime measures and it also mentions the associated health problems connected to the diagnosis. The Aim of the study: The main purpose of this work based on a small sample of patients was to verify their level of information and knowledge of the disease, compliance, participation in home blood glucose measurements and to determine the health complications associated with diabetes and its treatment. Methods: The study was carried out by questionnaire in a paper form. Data were obtained in a pharmacy during a short interview with 209 randomly selected diabetics type II. The questionnaire included two main characteristics of respondents (gender, age) and 6 simple targeted questions. Results: In the survey 59 % female and 41% male took part. The mean age of patients was 66.9 years. Respondents were diagnosed with DM on average 11.1...

The thesis deals with molecular detection of resistance in populations of pollen beetle based on genetic polymorphisms in the VSSC gene of this pest. Population samples were collected in 2016-2018 in the Czech Republic, mainly in the Southwestern Bohemian Region. A total of 57 populations of pollen beetles with different degrees of resistance were analyzed. Nucleotide mutations of populations were monitored in two parts of the VSSC gene of pollen beetles - DIIS4 - S5 linker / DIIS5 and DIIIS6 gene, which is located in the VSSC binding domain. These parts were amplified and sequenced by the Sanger method. In the alignment of final sequences, mutations were searched. After that, the effect of these mutations on the amino acid sequence was determined and the effect on the resulting VSSC protein conformation was assessed.

Nozokomiální infekce jsou v současné době významnou příčinou vzrůstající morbidity a mortality ve všech zdravotnických zařízení. Neznalost či ignorance metod prevence nozokomiálních nákaz může vést k závažnému ohrožení zdraví a života pacienta a výraznému zvýšení nákladů na léčbu. Práce komplexně představuje problematiku nozokomiálních nákaz a jejich efektů na lůžkové zdravotnické zařízení. Pozornost je věnována charakteristice procesu šíření nákaz, popsání současného stavu ve sledování a prevenci nákaz a konečně popsání situace v jedné nemocnici okresního typu.

This thesis deals with the measurement of blood glucose levels after consumption of selected foods (glucose solution, milk chocolate, rice sandwiches with corn, fruit snacks with apricots and broken buckwheat multigrain bread) at regular intervals. The first part of this thesis is pursued to the literature review, which provides a comprehensive overview of the metabolism of carbohydrates, fats and proteins. It also discusses the differences in the carbohydrate metabolism of healthy people with diabetes type 1 and 2 It acquaints the reader with the concepts of blood glucose, glycemic index and glucose-tolerance test. The practical part includes the measurement of glucose in capillary blood and questionnaire survey concerning state of health, eating habits and the disease incidence in a selected group of volunteers. The experiment involved 12 students of Mendel University in Brno. Their blood glucose levels were measured at regular intervals (0, 30, 60, 90 and 120 minutes) after ingestion of the food. The glucose was chosen as a standard. From the measured values were calculated glycemic indices, which represented 100 for glucose, milk chocolate 40+-17,7, sandwiches, rice with corn 76+-25,8, fruit snacks with apricots 49+-17,9 and multigrain bread buckwheat 68+-21,3. The results were statistically processed and the effect of individual foods tested on blood glucose was evaluated.
