Untersuchung der Gefäßdichte bei metastasierten und nicht-metastasierten Magenkarzinomen
In this study the blood vessel density in twenty nonmetastatic and thirty-three metastatic gastric carcinomas was immunohistochemically determined. The blood vessels were detected with two antibodies. One of these reacts with CD105 (Endoglin) and the other with CD34, a cell surface glycoprotein. …

Vascular and Mechanical Changes in Bone in Response to Chronic Ischemia and Mechanical Loading
… remodeling. An immunohistochemistry protocol for vessel marking in bone was also developed. Ischemia was induced in a mouse model to determine vascular and mechanical property changes in bone in response to hypoxia, and mechanical loading-induced remodeling was analyzed for vascular changes. Both …

Effekt einer transendokardialen kathetergestützten Applikation von Stromal cell derived factor 1[alpha] auf die linksventrikuläre Funktion im Herzinfarktmodell im Schwein
… size was determined by tetrazolium staining. Vessel density and myocardial remodelling were acquired by immunofluorescence staining. Immunofluorescence staining revealed significantly more vWF-positive vessels in SDF-1 alpha treated animals than in controls. Infarct size was similar in both …

Effekt einer Antagonisierung der alpha- v-Integrine auf Angiogenese, Wachstum und Metastasierung solider Tumoren in vivo
… of tumor angiogenesis including functional vessel density, red blood cell velocity (vRBC), vessel diameter and leukocyte endothelium interaction were analyzed using intravital microscopy. In an additional study the effects on growth and metastasis of subcutaneous A-Mel-3 were quantified. …

Risk of cervical lymph node metastasis in papillary thyroid carcinoma: Correlations with lymphangiogenesis and ultrasound features
… pathological factors based on the lymphatic vessel system and ultrasound features associated with tumor with cervical LNM. Among patients who had undergone thyroidectomy confirmed to be papillary thyroid carcinoma, we selected 126 age-sex matched paired patients without cervical LNM (group 1) …

A planned approach to high collision risk area
This thesis examines the transition of a vessel from the open ocean, where collisions are rare, to a high risk and heavy traffic area such as a Traffic Separation Scheme (TSS). Previous autonomy approaches generally view path planning and collision avoidance as two separate functions, i.e. a vessel …

<i>In Vivo</i> Murine Melanoma Tumor Responses to Nanosecond Pulsed Electric Field Treatment
… in a time-dependent manner. Examination of gross vessel and micro-vessel density indicated direct vascular damage to pre-existing vessels and antiangiogenic consequence on neovascular development concomitant with tumor self-destruction. A five-month survival study on 36 mice showed nsPEF Tx …

ANGIOTENSIN-(1-7): A NOVEL SMALL MOLECULE FOR THE TARGETED TREATMENT OF TRIPLE NEGATIVE BREAST CANCER
… the endothelial cell marker CD34 (a decrease in vessel density from 87.8 ± 6.4 in tumors from saline-treated mice to 32.0 ± 7.0 in tumors from Ang-(1-7)-treated mice, p < 0.05), suggesting that the heptapeptide inhibited angiogenesis. The reduced vessel density in Ang-(1-7)-treated tumors …

A study of Notch signalling in developmental angiogenesis
Blood vessel patterning during angiogenesis is a guided process. Endothelial tip cells located at the end of vascular sprouts are important for vessel guidance. One of the aims of my studies is to determine how endothelial tip cell formation is regulated. Previous studies have shown that the Notch …

Modulation of Alzheimer’s Disease Pathology by Collagen-Induced Rheumatoid Arthritis in APP/PS1 Mice
… In contrast, CIA reduced survival and vessel density and length with features of cerebrovascular pathology including vascular segments, thinner vessels, and atrophic string vessels. In the postsymptomatic stage, after the onset of amyloid plaque formation, CIA mice improved cognitive …

The Influence of Structure and Surface Biochemistry on Cell Function and Angiogenesis in Collagen Scaffolds
… chemistry properties on the formation of microvessels. Firstly, the influence of mould design on architectural features of collagen scaffolds fabricated using lyophilisation was assessed using micro-computed tomography (Micro-CT) and scanning electron microscopy (SEM). A range of mould designs …

Seedling xylem anatomy of two Banksia species relative to availability of groundwater
… experiment, it was possible to analyse the xylem vessel traits (vessel diameter (Vd), maximum vessel diameter (Dmax), vessel density (Dv) and vessel length (VL)) in root and stem tissue samples using ImageJ software. Analysis of vessel traits identified significant vascular tapering in both …

Paxillin-dependent control of tumor angiogenesis
… the growth of new capillaries from existing vessels- is required for tumor growth; however, tumor vessels exhibit abnormal structure and function, which impairs the targeted delivery of anti-cancer agents. While directional migration of capillary endothelial cells is critical for normal …

Regulation of VEGFR-3 expression and lymphangiogenesis in normal and inflamed tissues
… of lymphangiogenesis (i.e., new lymphatic vessel formation), is frequently associated with inflammation related to chronic disease and cancer. In the latter case, VEGFR-3 dependent lymphangiogenesis induced by inflamed tumors increases the incidence of distant metastasis, leading to …

Phylogenetic Studies of the Laurels and Heathers (Ericaceae: Ericoideae, Phyllodoceae and Cassiope Clades)
… evident in some anatomical characters, including vessel density and stem diameter. These results indicate that morphology in Cassiope is evolutionarily labile, and that anatomical characters may be tuned to local ecology.

Investigating lymphatic vascular remodelling during postnatal mouse mammary gland morphogenesis.
… development and adult homeostasis. Lymphatic vessels return interstitial protein-rich fluid to the bloodstream, transport immune cells during immune surveillance and infection and absorb lipids from the digestive tract (Alitalo et al., 2005; Tammela and Alitalo, 2010). The aberrant growth and …

Evaluating the regulation and function of adult mouse hippocampal neurogenesis induced from running
… in adult mice. Results showed that vasculature density increased in the granule cell layer, but not across the entire hippocampus of chronically running mice. These data suggest that increased blood vessel density from running is specific to the granule cell layer within the hippocampus. An …

Effects of Surface Characteristics of Hydroxyapatite and Substituted Hydroxyapatites on Protein Attachment and Angiogenesis
… simultaneous bone tissue formation and blood vessel growth through angiogenesis which is crucial for nutrient and waste exchange. Syn- thetic hydroxyapatite (HA) is one of the most widely studied bioceramics for BTE, due to its close resemblance to the mineral component of bone. As bone …

Stimulating angiogenesis into biomaterials through the delivery of growth factors
