A comparison of the diagnostic ability of vessel density and structural measurements of optical coherence tomography in primary open angle glaucoma. [PDF]

PLoS ONE, 2017
PURPOSE:To compare the diagnostic abilities of vessel density measurements of the optic nerve head (ONH), peripapillary and macular regions on optical coherence tomography (OCT) angiography in eyes with primary open angle glaucoma (POAG) with that of the

Pathologic evaluation of tumor-associated macrophage density and vessel inflammation in invasive breast carcinomas [PDF]

, 2017
Tumor-associated macrophages (TAMs) are major constituents of the tumor microenvironment in solid tumors and have been implicated as mediators of tumor progression, invasion and metastasis.

Awake chronic mouse model of targeted pial vessel occlusion via photothrombosis [PDF]

, 2020
Animal models of stroke are used extensively to study the mechanisms involved in the acute and chronic phases of recovery following stroke. A translatable animal model that closely mimics the mechanisms of a human stroke is essential in understanding ...

Lymphatic vessel density and function in experimental bladder cancer

BMC Cancer, 2007
The lymphatics form a second circulatory system that drains the extracellular fluid and proteins from the tumor microenvironment, and provides an exclusive environment in which immune cells interact and respond to foreign antigen. Both cancer and inflammation are known to induce lymphangiogenesis.

Lymphatic vessel density and prognosis in cutaneous melanoma [PDF]

British Journal of Cancer, 2004
Sir, Recent studies have focused on the possible prognostic importance of lymphatic vessel density (LVD) in malignant melanoma, and we have read the paper by Shields et al (2004) with great interest. Based on their data, the authors suggest that the assessment of lymphatic vessel density (LVD) might give prognostic information in cutaneous melanoma.

Flow correlated percolation during vascular network formation in tumors

, 2005
A theoretical model based on the molecular interactions between a growing tumor and a dynamically evolving blood vessel network describes the transformation of the regular vasculature in normal tissues into a highly inhomogeneous tumor specific capillary

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.
