Reconstruction of Railway Station Svitavy
Marek, Josef ; Rotschein, Petr (referee) ; Valehrach, Jan (advisor)
The goal of this thesis was to design the reconstruction of the railway station Svitavy. The line speed was rised from the current value to 160 km·h-1. New platforms were designed, therefore the railway substructure and the drainage were adjusted accordingly. Also, the effective length of the main tracks was extended to 740 m.

Sledování vlivu dopravy na obsah těžkých kovů u modrých a bílých odrůd u dopravně zatížených komunikací
Marek, Josef
The diploma thesis is focused on determining the influence of transport on the content of heavy metals in white and blue grape varieties and their subsequent products from vineyards near traffic-laden roads and reference, traffic-free locali-ties and its relation to heavy metal content in air and soil in monitored vineyards. The analysis of elements in grapes and their subsequent products is performed in various stages of wine production, air analysis by analysis of weekly sampling and soil analysis by one-time sampling in the monitored vineyards in the period befo-re harvest. The instrumental method of inductively coupled plasma mass spectrometry was used for the measurement.

Role of echocardiography in cardiac resynchronization therapy
Marek, Josef ; Linhart, Aleš (advisor) ; Mandysová, Eva (referee) ; Ozábalová, Eva (referee)
Cardiac resynchronization therapy (CRT) is an established treatment of patients with heart failure with reduced ejection fraction associated with QRS complex prolongation. However, about 30% of patients do not respond to CRT favorably, more so patients with shorter QRS duration and QRS morphology other than typical left bundle branch block. Echocardiography plays a crucial role in management of all those patients. Echocardiographic assessment of myocardial mechanics can quantitate myocardial deformation and find myocardial segments that are latest mechanically activated in a dyssynchronously contracting left ventricle. Left ventricular (LV) lead placement in this area is associated with clinical response to CRT. On the other hand, lead placement within a scar has been associated with bad prognosis. The aim of this work was to investigate whether left ventricular lead placed close to the site of latest mechanical activation is beneficial especially in patients with shorter QRS durations or atypical QRS morphology. This has been done by analyzing data of the randomized trial STARTER, which compared echo-guided LV lead navigation to routine empirical lead placement. The STARTER trial proved clinical benefit of echo-guided LV lead placement towards the site of latest mechanical activation. In our...

The diagnosis and surgical treatment of primary hyperparathyroidism
Libánský, Petr ; Adámek, Svatopluk (advisor) ; Marek, Josef (referee) ; Haruštiak, Svetozár (referee)
Surgical management of primary hyperparathyroidism is a very effective method. The target is to cure primary hyperparathyroidism and to reach normal calcium levels. This results in an improvement of health condition and resolution or at least moderation of symptoms. Complications are infrequent and mortality is very low. Surgical management is definite, safe and effective. Number, location and surrounding structures of parathyroid glands with emphasis on parathyroidectomy were studied on 101 cadaverous bodies. We recommend the performance of parathyroidectomy in a circumscribed area 2 cm in diameter, 1 cm cranially to the intersection of the inferior thyroid artery and recurrent laryngeal nerve. We identified 75% of samples as parathyroid glands. The rest of collected samples were lymph nodes, fat particles and thyroid or lipothymic tissue. During the course of this study, we have tested techniques of miniinvazive procedures. In the following part, the bony, metabolic and biochemical syndromes are evaluated. We presented series of 151 patients that have been operated with the diagnosis of primary hyperparathyroidism. The survey is focused on the primary hyperparathyroidism and concomitant diseases and on the possible sequelae in the postoperative period. The special part is describing 10 clinical...

Genetic and Hormonal Regulation of Children's Growth
Vosáhlo, Jan ; Lebl, Jan (advisor) ; Marek, Josef (referee) ; Vaňková, Markéta (referee)
Genetic and Hormonal Regulation of Children's Growth MUDr. Jan Vosáhlo Abstract Growth in childhood is a complex process of changing the body, which can be disrupted by various illnesses including endocrine disorders, particularly growth hormone deficiency. Tumors or other processes affecting hypothalamic-pituitary area can be a postnatal cause of GHD; prenatal causes include 1) developmental disorders of the pituitary as part of complex syndromes, 2) developmental disorders of the pituitary due to defects in regulatory genes and 3) defects in genes involved in the synthesis and secretion of GH. The first topic of the thesis was septo-optic dysplasia - a complex syndrome involving optic nerve hypoplasia, structural brain abnormalities and pituitary dysfunctions. We extensively described phenotype in 11 Czech patients; we observed both complete SOD and incomplete forms variously combining two of the three main components of the syndrome. The cohort then became a part of an international study of 68 patients, in which we studied the phenotype in dependence on the brain morphology. We found correlation between the severity of clinical symptoms and the degree of septum pellucidum abnormities and also a correlation between hippocampus and falx abnormities and neurological symptoms. As the second topic we studied...

Contribution to radiodiagnostics and to treatment of chosen pathological lesions of femur in childhood and in adults
Horák, Martin ; Poučková, Pavla (advisor) ; Marek, Josef (referee) ; Vítek, František (referee)
7 Abstract (AJ) Introduction Radiology examination using specialized modern imaging methods, including CT and MRI, is essential in the diagnosis of congenital and acquired diseases of the musculoskeletal system. The first part of the dissertation deals with certain congenital defects of the short femur, known in the literature as proximal femoral focal deficiency (PFFD). This part summarizes our experience with the radiological findings in the preoperative and postoperative period, with the main attention to the vascular supply to the affected area. The second part of the presentation deals with some aspects of autologous chondrocyte transplantation fixed at two different carriers implanted into post-traumatic articular cartilage defects of the distal femur. Radiological findings are evaluated in the relation to the histopathological findings. Objectives The first part of the study after the distribution of patients with PFFD by current commonly used radiographic classification sets the objective in the extent of scans of the hip joints to specify diagnosis PFFD in each patient and to evaluate in detail changes in the area of disability, especially a course of blood vessels. The evaluation of the radiation burden of repeated X-ray measurements was done with respect to the age of the patients. Tissue samples...
