The linking of angiogenesis to contractile performance and substrate metabolism in the hypertrophied and failing heart
… been suggested that a failure of angiogenesis (capillary growth) to keep pace with myocyte expansion is the driving force which pushes hypertrophied hearts into a state of failure marked by contractile dysfunction and alterations in the mechanisms governing energy production. The aims of this …

Adaptation to environmental stress in the human placenta
The placenta mediates fetal growth by acting as a substrate for nutrient exchange between the mother and the fetus. Environmental factors such as altitude have been shown to result in reduced maternal-fetal exchange leading to reduced birth weight. To determine if differences in gene expression …

Systematic and local regulation of angiogenesis, and other adaptations, in response to hypoxia
… hypoxia, local or systemic, which would initiate capillary growth in different tissues, and determine whether manipulation of the pathway (by HIF stabilisation) would enhance this response. A systemic response to hypoxia led to increased capillarity in the heart and diaphragm, and in both the …

The Effects Of Exercise On Capillary Supply To The 'transition Zone' Of Infarcted Rat Hearts
… reduced oxygenation, possible due to reduced capillary supply, I quantified the capillary supply to the region adjacent to the necrosis in infarcted hearts, and compared this to values in healthy myocardium.;Myocardial infarcts were produced in rats by ligating the left coronary artery (LCA) …

Einfluss des ACE-Hemmers Quinapril auf das Kapillarwachstum - morphologische Charakterisierung am chronisch ischämischen Rattenherzen
Zielsetzung der vorliegenden Arbeit war es, das in unserem Labor etablierte Modell der chronischen Koronarstenose der Ratte morphologisch zu charakterisieren. Besonderes Augenmerk galt hierbei dem mikrovaskulären Remodeling zwei Wochen nach myokardialer Ischämie. Darüber hinaus sollten Effekte des …

Numerische Simulation von Erstarrungsprozessen : Wege zur mehrskaligen Modellierung ausgehend von Mikrostrukturmodellen
… from the separation allows to describe the growth of a periodic array of equiaxed dendritic nuclei which interact through the released latent heat over a macroscopic temperature field. At first, analytical investigations of the two-scale model are discussed in this PhD thesis. In these …
