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...

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.

Insulin resistance (IR) is considered to be an important factor influencing the progression of atherosclerosis and is associated with higher morbidity and mortality. IR is a common feature of diabetes mellitus Type 2 and obesity. Many authors consider IR being the crucial abnormality of the metabolic syndrome which is characterized by the essential hypertension, hyperliproteinemia, visceral obesity, endothel dysfunction and many other abnormalities. Impaired insulin action (IR) is also described in diabetes mellitus Type 1, however this phenomenon has not been fully explained. The subjects of dissertation thesis was directed on the IR importance in diabetic Type 1 patients as well as on the renin angiotensin system inhibition in patients with IR and metabolic syndrome with impaired glucose homeostasis. Hyperinsulinemic euglycemic clamp is used in combination with indirect calorimetry to estimate the IR in vivo in humans. In our project we focused on a) the existence of the metabolic inflexibility phenomenon in type 1 diabetic patients b) the methodological evaluation of the hyperinsulinemic euglycemic clamp procedure in the same group c) the influence of renin angiotensin system inhibition with angiotensin II type 1 receptor inhibitor telmisartan in patients with metabolic syndrome and impaired glucose...

The Master's thesis entitled "Gestational Diabetes Diet" deals with the issue of eating habits and a lifestyle of women diagnosed with gestational diabetes mellitus during pregnancy. The theoretical part of the thesis describes the definition, causes and a mechanism of origin, consequences for mother and fetus and also deals with the diagnostic procedures and all possibilities of treatment of this disease. In this part, the diagnostic method analyzed by using the oGTT stress test and a diabetic diet - that together with other preventive measures (mainly physical aktivity) is the first choice in the treatment of pregnancy diabetes - are described in more details. The practical part of this master's thesis contains the results of a questionnaire survey in two groups of pregnant women - with already diagnosed gestational diabetes and before its diagnosis in the oGTT test. It also contains the results of the analysis of women with GDM diets. The analysis were processed by the NutriPro Expert diet program and the results are then compared with the current nutritional recommendations of the Czech Republic for pregnant and nursing women. The aim of this work was to map the eating habits and lifestyle of women with gestational diabetes and find out whether they meet current nutritional recommendations or...

Magnetic resonance spectroscopy (MRS) is a noninvasive technique that enables to follow metabolic processes in selected tissues in vivo. Recently the attention has been focused on metabolic mapping in target organs of insulin action to describe the pathophysiology of insulin resistance. The aim of our study was to present the practical application of ³¹P (phosphorus) MRS and ¹H (proton) MRS in metabolic studies of skeletal muscle in insulin resistant subjects and in subjects with impaired fasting glucose. The third study was aimed to evaluate the brain metabolism with ¹H MRS in healthy controls and subjects with type 1 diabetes during hyperinsulinemia. ¹H and ³¹P MRS were performed using a MR Scanner Siemens Vision operating at 1,5 Tesla. To assess the parameters of glucose metabolism and insulin action oral glucose tolerance test and hyperinsulinemic euglycemic clamp were performed. The study 1 was aimed to evaluate the skeletal muscle (m. soleus) energetic metabolism in the offspring of hypertensive parents (OH) with a higher level of insulin resistance. The concentrations of selected high energy phosphates (phosphocreatine, inorganic phosphate, adenosintriphosphate, phosphomonoesters, phosphodiesters) were evaluated with ³¹P MRS. Their amount in OH was comparable to healthy controls. However we...

The main aim of this thesis is to investigate the role of Impl2 gene in the regulation of immune response to bacterial infection in Drosophila melanogaster. The theoretical part provides a conceptual background concerning immunity in drosophila and also it summarizes what is known about the Impl2 gene. In the practical part, the function of Impl2 gene during infection is examined, starting with the location of its production during immune response, the changes of Impl2 gene amount during infection and its essentiality for a proper immune response. Furthermore, it examines the metabolic changes underlying an immune activation in connection to Impl2 gene. Last but not least, it tests how Impl2 gene is connected with the mobilization of energy during Chill Coma Recovery assay.

Title: Mountain tourism for diabetics with an insulin pump Objectives: The aim of this study is to find out whether it is suitable for patients with type 1 diabetes mellitus treated with an insulin pump to undergo physical activity in the form of mountain tourism, as the more intense physical aktivity affects blood glucose levels and whether patients are able to work with advanced insulin pump functions. Methods: The work is conceived as an observational study of the Medtronic educational project. One day mountain hike trip of a distance about 30 km was attended by 40 patients (men and women) with diabetes aged 15-25 years. Non-invasive methods were used. The data was obtained by monitoring insulin pump probes, glucometers and continuous monitoring, which were further evaluated using the CareLink Pro software. Results: Physical activity in the form of mountain tourism is suitable for patients with DM1 treated on an insulin pump. 80% of the probands did not have a risk status of hypoglycaemia, and even though the determined normoglycemia for research was performed by a larger number of adults as opposed to children, this FA has a demonstrable effect on blood glucose levels. It also brings positive benefits for patients because they learn how to work better with advanced insulin pump functions....

(EN) GH/IGF-1 axis components (GH, growth hormone receptor (GH-R), IGF-1, IGF-1 receptor (IGF-1R), IGF-binding proteins (IGFBPs)) participate in the control of glucose metabolism, inflammatory processes as well as cell proliferation and differentiation, including adipocytes and monocytes. The aim of the present study was to evaluate the role of local mRNA expression of GH/IGF-1 axis components in subcutaneous adipose tissue (SCAT) and peripheral monocytes (PM) in the development of insulin resistance and differences of adipose tissue mass in following groups of patients: obese females with and without type 2 diabetes mellitus and subjects with active untreated acromegaly. A total number of 66 subjects were included in the study: obese females without type 2 diabetes mellitus (OB), obese females with type 2 diabetes mellitus (T2DM), acromegalic patients (AC) and healthy lean control subjects (C). T2DM underwent 2 weeks of very-low- calorie diet (VLCD - energy content 2500 kJ/day). According to our results we suggest that decreased mRNA expression of IGF-1, IGF-1R, IGFBP-2 and IGFBP-3 in adipose tissue of T2DM subjects may contribute to changes of fat differentiation capacity and the increased IGF-1R mRNA expression in peripheral monocytes in these patients may play a role in the regulation of...
