Possibilities of Portal Vein Reconstruction during Surgical Treatment of Pancreatic Cancer - Experiment on a Large Animal Introduction: Pancreatic cancer is a fatal malignancy that is known as one of the leading causes of cancer mortality worldwide. The only potentially curative treatment is radical surgical resection. Because of the lack of early symptoms, the diagnosis is usually made in advanced stages of the disease. In the majority of patients, the tumor is already locally advanced or it has distant metastases at the time of diagnosis. Pancreatic cancer tends to infiltrate the portal vein (PV) or the superior mesenteric vein (SMV). Nowadays, resection of infiltrated parts of PV/SMV is recommended in specialized centers. There are several established techniques of PV/SMV reconstruction. The use of allogeneic venous grafts seems to be a method with minimal risk of adverse effects but there is only limited experience with these grafts. The optimal anatomical origin of allogeneic venous grafts for PV/SMV reconstruction remains unknown. Aims: The aim of this experiment was to compare two types of allogeneic venous grafts used for PV reconstruction in a large animal model of pancreatico- duodenectomy. These grafts were harvested from the systemic venous system (inferior caval vein grafts - IVC grafts) and...
Návrh ochrany půdy před vodní erozí v katastrálním území Kobylí

Erosion is global issue. In Czech republic, soil is threatened mainly by water erosion, approximately 50 %. This phenomenon causes irreversible soil loss and degradation. In the soil there are chemical and physical changes and changes of structure and texture. The changes are very dangerous because distinctly decrease soil fertility. In thesis is solved soil loss by water erosion in cadastral area Kobylí. Firstly I deal with concept of erosion and its types. Further I describe calculation methodology of water erosion by using Wishmeier-Smith equation and possible methods erosion control measures. In conclusion I evaluate soil loss and I suggest suitable erosion control measures on endangered areas.
