Role of nitric oxide in the regulation of apoptosis and cell cycle during various pathological conditions
Kučera, Tomáš ; Martínek, Jindřich (advisor) ; Čech, Svatopluk (referee) ; Mokrý, Jaroslav (referee)
Nitric oxide is a free radical that plays number of important roles in the organism. Among the best known are its effects in cardiovascular, nervous and immune system. However, as the knowledge about this molecule is expanding, it is becoming obvious that NO is involved in many other physiological processes. The importance of NO is given also by its ability to influence various pathological processes. It was found that the role of NO can be both beneficial and detrimental depending on various circumstances, mainly on the local level of NO production. The potential of nitric oxide to influence the process of programmed cell death and cell proliferation belongs to its important properties. There were reported numerous controversial effects on these processes, which result depended on the particular cell type and its actual physiological or pathological circumstance. The aim of the thesis was to contribute to the better knowledge of the NO role in programmed cell death - apoptosis and in cell proliferation. With respect to the currently known specific effects in various tissues and organs the research was focused on several different pathological conditions. At the same time, several in vitro models were combined with in vivo undertaken observations. The experimental rats and primary rat hepatocytes were used...
Demands on radiology assistants at three-dimension visualization
ČECH, Svatopluk
Fast development of three-dimension visualization in radiology relates to more sophisticated diagnostic machines, with the development of computer technology and digitizing. Increasing demands on radiology assistants in operating programs of reconstruction images increase the importance of their position at modern radiology workplace. Three-dimension images offer exact and undistorted images of patient's anatomy, they give better diagnostic information for physicians - radiologists and more objective imagination for physicians - clinicians. They find the application in a number of examinations in skiagraphy, angiography, computer tomography, magnetic resonance and ultrasonography. We can say that three-dimension visualization substitutes other examination which are invasive and represent certain complications for a patient. The question is whether some three-dimension examination can reduce radiation load of a patient. We can suppose that digital imaging methods will be part of near future and three-dimension visualization and further development of computer technique will acquire still more impact in diagnostic of many diseases.
