Anti-cytoskeletal antibodies in patients with multiple sclerosis and other neurological diseases
Švarcová, Jana ; Matouš-Malbohan, Ivan (advisor) ; Tlaskalová - Hogenová, Helena (referee) ; Průša, Richard (referee)
This thesis focuses on the role of anti-cytoskeletal antibodies in various neurodegenerative diseases. Autoantibodies against different axonal cytoskeletal proteins, such as the light (NF-L) and medium (NF-M) subunits of neurofilament and tubulin (TU), in serum and cerebrospinal fluid may be generated in response to the release of cytoskeleton from damaged neurons. The aim of this study was to assess autoimmune involvement in amyotrophic lateral sclerosis (ALS) as well as to evaluate antibody light and medium neurofilament subunit in serum and cerebrospinal fluid (CSF) of patients with ALS. Furthermore, we were interested in the relationships among these antibodies in the serum and in the CSF as well as between the two anti-NF antibody subtypes. Secondly, the aim was to compare the levels of anti-tubulin antibodies (anti-TU) in cerebrospinal fluid and serum in multiple sclerosis (MS) disease, using bovine tubulin as the antigen in one enzyme-linked immunosorbent assay (ELISA) method (anti-TUb antibodies) and a synthetic neuron-specific octapeptide of tubulin in a second ELISA method (anti-TUs antibodies). In the observed groups of ALS patients, serum levels of anti-NF-L antibodies were higher in ALS patients than in controls and serum anti-NF-L antibodies and intrathecal anti- NF-M antibodies were...

Biochemistry of polyphenols effects in the treatment of vascular disease
Kondrashov, Alexey ; Štípek, Stanislav (advisor) ; Pecháňová, Olga (referee) ; Matouš-Malbohan, Ivan (referee)
This Ph.D. thesis deals with the deep analysis of polyphenols effects toward vascular disorders. This work provides a number of experimental results of studying both the effects of natural bioactive compounds in red wines and potatoes, and their application to the experiments which includes experimental animal models with spontaneous hypertension. Methods and equipment used in experimental studies allowed us to make several new statements regarding the universal nature of the relationships between the antioxidant capacity and the polyphenolic content in examined foodstuffs. Besides this it is also recognized that food is a source of minerals which also contribute to the total antioxidant capacity and therefore may have influence the endogenous antioxidant enzyme system by providing the essential cofactors. Experimentally we have found that the concentrations of magnesium known for its therapeutic action in wine and red wine extract are comparable to the mineral waters recommended for the treatment and prevention of cardiovascular and metabolic diseases. Moreover, synergistic interactions between selected minerals have been found. The key issue of bioavailability of polyphenols for supporting the idea of the beneficial effects of diet rich in fruits and vegetables toward vascular disease prevention...

Biochemical parameters of energy metabolism in cerebrospinal fluid in inflammatory and non-inflammatory CNS diseases.
Bořecká, Klára ; Fialová, Lenka (advisor) ; Bartoš, Aleš (referee) ; Matouš-Malbohan, Ivan (referee)
The basic examination of the cerebrospinal fluid provides a quick orientation in the diagnostic algorithm of CNS diseases about the nature of the pathological process. The current evaluation of cytology and biochemical parameters of glucose metabolism reports about the cells present and at the same time about the level of their activation. The aim of the work was to investigate the relationship between biochemical and cytological findings in cerebrospinal fluid in a large data set (n = 8 178), or confirm the hypothesis of a significant alteration in the Coefficient of Energy Balance (CEB) in cytological classes typically accompanying oxidative burst of phagocytes. CEB was subjected to analysis and comparison with other energy parameters (lacto-glucose ratio, gluco-lactate ratio, concentration of lactate and glucose in cerebrospinal fluid). The relationships between blood and cerebrospinal fluid glucose and lactate concentrations were investigated. CEB values were statistically significantly different in cytological groups, which reflected purulent inflammation, tumor involvement or infection by potential intracellular pathogens, the hypothesis was confirmed. Other energy parameters excluding glycorrhachia distinguish these cytological groups as well as CEB. There are inaccuracies in the derivation...

Pathobiochemistry of inhibin A and its application in prenatal screening of chromosomal abnormalities
Loucký, Jaroslav ; Průša, Richard (advisor) ; Procházka, Martin (referee) ; Matouš-Malbohan, Ivan (referee)
Aims: Currently, prenatal testing is based on an ultrasound examination, the testing of certain biochemical markers and most recently, also on the analysis of fragments from the extracellular DNA of the fetus in the mother's blood. The aim of this work was to verify whether inhibin A testing during pregnancy can help improve the results of prenatal screening (risk assessment) for Down syndrome and thus reduce the number of unnecessarily invasive procedures. Methods: The concentrations of inhibin A were measured using chemiluminescent immunoassay with paramagnetic particles on the Access system from Beckman Coulter. Risk assessments of screenings were performed using Alpha software, LMS. The results were compared in two groups of screening tests, a triple test and an integrated test. In the first case, the risks in these two groups were determined without inhibition A and included only high-risk results. Subsequently, the inhibin A results were included in the screening protocols and the existing risks were revised. Results: The first group of screening tests (triple test) included a total of 277 pregnant women. The second group (integrated test) included 91 pregnant women. The resulting risk for pregnant women without the determination of inhibin A was higher or equal to 1:300 (triple test),...
