Úloha proteinkinázy C v patogenezi inzulinové rezistence a jejích komplikacích / The role of protein kinase C in the pathogenesis of insulin resistance and its complications

Marková, Irena January 2010 (has links)
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...

Sledování tvarových změn kosterního svalu v závislosti na povrchové teplotě těla / Observing of the skeletal muscle shape changes depending on human body surface temperature

Frýdová, Aneta January 2015 (has links)
Title: Observing of the skeletal muscle shape changes depending on human body surface temperature Objectives: The aim of this work is to observe the cross-section changes of the m. rectus femoris depending on human body surface temperature changes. The cross section of the muscle was characterized by two dimensions: VDDM (ventrodorsal dimension of muscle) and LMDM (lateromedial dimension of muscle). The body temperature was affected by local positive and negative thermotherapy methods. Methods: The first part of the experiment focused on the selection of appropriate local positive and negative thermotherapy forms. Four of them were selected (two positive thermotherapy methods - Peat thermotherapy bags and infrared heater InfraPhil HP3616 and two negative thermotherapy methods - gel bag Cryoflex and Cryogen 3 device) for the main research. Twelve subjects participated on the main experiment. Selected local positive thermotherapy methods were applied on the centre of the subject's thighs, subsequently selected negative thermotherapy methods were applied. The body surface temperature was measured immediately before application, after 30 minutes of positive thermotherapy and after subsequent negative thermotherapy application. Ultrasound images of m. rectus femoris were taken at same time. VDDM and...

Kopecká, Barbora January 2018 (has links)
Title: The effect of intensity of voluntary isometric contraction on rheological characteristics of skeletal muscle tissue in vivo, in situ Objectives: The main aim of this study is to determine the effect of intensity of isometric voluntary contraction of skeletal muscle on its viscoelastic characteristics. The work also aims to contribute to the verification of myotonometer as an objective diagnostic instrument and compares it to known methods for evaluation of muscle tone, or its partial characteristics. Methods: We used myotonometer - utility model 29456 for evaluation of changes of stiffness and viscous behavior of skeletal muscle in vivo, in situ in 20 healthy volunteers. The values were compared during 0%, 20%, 35% and 50% of maximal strength of isometric contraction of finger flexors, controlled by hand-held dynamometer. Results: We concluded that both stiffness and viscous behavior of skeletal muscle increases with higher intensity of isometric voluntary contraction. Keywords: myotonometer, skeletal muscle, viscous behavior, stiffness, muscle tone

Použití magnetické rezonance spektroskopie při studiu glukózového metabolismu / The use of magnetic resonance spectroscopy for studying glucose metabolism

Kratochvílová, Simona January 2018 (has links)
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...

Vývoj AMPK v kosterním svalu během časného postnatálního vývoje / Maturation of AMPK in skeletal muscle during early postnatal development

Hansíková, Jana January 2013 (has links)
AMP-activated protein kinase (AMPK) is an important metabolic sensor in eukaryotic organisms and it plays an important role in regulating energy homeostasis, at both the cells and the whole organism. AMPK controls glucose and lipid metabolism by direct stimulation of enzymes or by long term stimulation of the gene expression of energy metabolism. Skeletal muscles significantly contribute to the total body weight and metabolic rate and to the maintenance of glucose homeostasis. Due to the ability of the muscle to increase energy expenditure to 95% of whole-body energy expenditure, could be the proper development and programming of metabolism in the early postnatal period crucial for the further development of the organism in adulthood. Early postnatal development leads to substantial changes in energy requirements of the body and this suggests the significant involvement of AMPK in this period. The aim of this thesis was to study the activity and expression of isoforms of the catalytic subunit of AMPK in skeletal muscle during early postnatal development of both mouse strains A/J and C57BL/6 that differ in the development of diet-induced obesity. The next task was to analyze the expression of selected genes involved in energy metabolism - GLUT4, PGC-1α and UCP3 that AMPK regulates. It was found that the...

Burian, Martin January 2016 (has links)
Diploma thesis Archaeozoology Klementinum in Prague studies the archaeozoological remains from the Klementinum in Prague dated between the late 11th and 15th century. The work is divided into two parts - the theoretical and the empirical part. The theoretical part focuses on the economic background of the medieval city and nutrition of its inhabitants. Other chapters focus on the historical context of Klementinum and characteristics of the archaeological research, which took place on its territory in 2012 - 2014. The research consists of material and methods and subsequent evaluation of the obtained data, which are discussed and compared with literature. The aim of this diploma thesis is to bring interpretation of human diet of people whom lived at the site of today's Klementinum in Prague, in different time periods (from the beginning of the peak to the late Middle Ages) through the analysis of animal bones. In conclusion this diploma thesis found the economic base of the territory and which animals have been consumed on the site. In different periods was observed increasing richness of species for documented animals. Also there was discussed the impact of arrival of the Dominican convent on the breding economy after a year 1232nd.

Faktory ovlivňující metabolismus glukózy a zánětlivou reakci u kriticky nemocných pacientů / Factors affecting glucose metabolism and inflammatory response in critically ill patients

Kotulák, Tomáš January 2014 (has links)
Hyperglycemia in critically ill patients was considered for many years an adaptive response to stress conditions being present in both patients with and without previous history of diabetes. Hyperglycemia is caused mainly by peripheral insulin resistance induced by the factors acting counteracting insulin signalling at the postreceptor level. Furthermore, hyperglycemia itself can then increase serum levels of pro-inflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin-6 (Il-6) and interleukin-8 (Il- 8) and others. On the contrary, peripheral insulin resistance induced by pro- inflammatory cytokines may further potentiate hyperglycemia. White adipose tissue represents in addition to its energy storage function also a very active endocrine active organ. In addition to regulation of a number of metabolic processes it also significantly modulates the inflammatory response. In critically ill patients, adipose tissue changes its morphology, i.e. the adipocytes are shrinking and adipose tissue is abundantly infiltrated by macrophages. Paradoxically, overweight and obese critically ill patients have lower mortality than underweight, lean and morbidly obese subjects. In our studies, we selected population of the patients undergoing elective major cardiac surgery with extracorporeal...
