The aortic aneurysm is a common disease that is particularly relevant due to the feared complication of rupture with an extraordinarily high mortality rate. The valid recording of aortic growth is essential, since therapeutic decisions that are relevant for the patient's outcome depend on it. In the present work, the growth behavior of the aorta was quantified, CT-morphological and clinical growth predictors were derived and growth rates were compared on the basis of different parameters. Details Title: Predictors for the...

We know almost everything about individual nerve cells and the knowledge about the function of entire brain regions is increasing every day. However, if we look for explanations of the functions of cell clusters with thousands or even millions of neurons, then there is a gaping void. We do not know it. Or rather, we didn't know, because this book develops and describes the signal processing and the way information is stored in our brain and in neural networks in...

Alveolar echinococcosis (AE) is considered the most dangerous parasitic zoonosis in Central Europe and is caused by the second larval stage of the small fox tapeworm Echinococcus multilocularis. In addition to humans, non-human primates can also contract AE, which is characterized by a gradually progressive course of the disease and is usually fatal if left untreated. Due to the increase in spontaneous cases of AE in macaques at the German Primate Center, the changes associated with AE were extensively pathomorphologically...

Many questions remain in the design and evaluation of automated cleaning processes for surgical instruments. This work describes a model for evaluating the process and its optimization. A total of sixteen influencing factors (measuring method, machine, process parameters) on the cleaning result are statistically examined. Tests are carried out in parallel using various measuring methods (TOC, BCA) and test soiling on self-constructed, demountable test specimens. The results are compared with processes in clinics. A simplified model of practical process evaluation...

The ciliated cells of the respiratory epithelium play an important role in the pulmonary mucociliary clearance mechanisms. Ultrastructural changes in the cilia of these cells can therefore be an expression of pathogenetic processes in the context of respiratory diseases. Against this background, ultrastructural indications of ciliary dyskinesia in common marmosets (Callithrix jacchus) of different ages and taking into account clinically inapparent pulmonary changes were determined in the present work in order to make a contribution to the validation of common...
