Lymphatic vessel density in radical prostatectomy specimens

Human Pathology, 2008
Formation of new lymphatic channels, or lymphangiogenesis, has been associated with poor prognosis in a number of human cancers. Its prognostic significance in prostate cancer is uncertain. We analyzed 122 radical prostatectomy specimens. Immunohistochemistry for lymphatic vessels was performed using a mouse monoclonal antibody reactive with an O ...

Quantifying Lymphatic Vessel Density in Human Tissue Samples

2022
The development of new blood and lymphatic vessels, through the process of angiogenesis and lymphangiogenesis, respectively, is critical to the development and growth of tumors, and integral to the process of metastasis. Lymphatic vessel density can be assessed as a surrogate measure of lymphangiogenesis in human tissue samples.

The Prognostic Role of Vessel Productive Changes and Vessel Density in Oligodendroglioma

Journal of Neuro-Oncology, 1999
The recognition of the anaplastic variant of oligodendroglioma is difficult, since it is not easy to identify histological prognostic factors. Among the latter, vascular productive changes have been inconsistently put in relation with survival. In 95 cases of operated oligodendrogliomas, endothelial cell hyperplasia, microvascular proliferations and ...

Lymphatic vessel density is significantly increased in melanoma

Journal of Cutaneous Pathology, 2004
Background:  Melanoma is well known for its ability to involve regional lymph nodes in the early stage. However, the presence of lymphangiogenesis in melanoma is still controversial due to lack of lymphatic‐specific markers. The purpose of this study was to determine the intra‐ and peritumoral lymphatic vessel density (LVD) using a novel lymphatic ...

Chronic vessel ligation increases vessel wall strain and vessel length density in mesenteric microvascular networks

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
To study the role of hemodynamic stresses in microvascular network remodeling, a ligation strategy was developed to locally alter pressure and wall strain throughout the microvessel network of a single mesentery window. Additionally, a network model was developed to calculate the pre- and post-ligation pressures throughout the affected mesenteric ...

Vessel Density Ratio

Journal of Computer Assisted Tomography, 2006
We hypothesized that a "culprit" lesion in acute coronary syndrome (ACS) should have low overall vessel lumen and plaque density on multidetector computed tomography-assisted coronary angiography (MDCTA) because of lower calcification and the presence of occlusive thrombus.

Vessel Density Mapping of Cerebral Small Vessels on 3D High Resolution Black Blood MRI

2023
AbstractCerebral small vessels are largely inaccessible to existing clinical in vivo imaging technologies. This study aims to present a novel analysis pipeline for vessel density mapping of cerebral small vessels from high-resolution 3D black-blood MRI at 3T.

Lymphatic vessel density, microvessel density and lymphangiogenic growth factor expression in colorectal cancer

Colorectal Disease, 2007
AbstractObjective  Microvessel density (MVD) has been studied as a prognostic marker in human cancers. Quantification of lymphatic vessel density (LVD) is now possible by using new antibodies. Expression of the lymphangiogenic growth factors, VEGF‐C and VEGF‐D, is associated with poorer clinicopathological outcomes in various tumours.
