Comparison of the endocytoscopic and clinicopathologic features of colorectal neoplasms

Endoscopy International Open, 2016
Background and aim: Permeation of a vein or lymphatic vessel by a tumor is a key risk factor for lymph node metastasis. We examined the features of colorectal tumor vessel permeation using endocytoscopy, an ultra-high magnifying endoscopic system ...

Automated vessel centerline extraction and diameter measurement in OCT Angiography

Current Directions in Biomedical Engineering, 2021
Optical Coherence Tomography Angiography (OCTA) is a non-invasive imaging technique that enables the visualization of perfused vasculature in vivo. In ophthalmology, it allows the physician to monitor diseases affecting the vascular networks of the ...

One single drug-coated balloon for all shapes/diameters? Neointimal proliferation inhibition in porcine peripheral arteries.

PLoS ONE, 2023
BackgroundLong diseased vessel segments of peripheral arteries may display irregular shapes with different diameters. The aim of this study was to investigate inhibition of neointimal proliferation in porcine peripheral vessels with different diameters ...

Analyses of Xylem Vessel Size on Grapevine Cultivars and Relationship with Incidence of Esca Disease, a Threat to Grape Quality

Applied Sciences, 2022
Esca disease is one of the most important grapevine trunk diseases. It seriously reduces the quality and quantity of grapevine production, and results in a shorter vineyard lifespan. Previous studies have suggested that wide xylem vessel diameter favours

Hydraulic architecture of lianas in a semiarid climate: efficiency or safety?

Acta Botânica Brasílica, 2015
Xylem anatomical traits can provide insights regarding the mechanisms affecting the distribution of vascular plants across environmental gradients. In this study, we aimed to investigate the hypothesis that lianas occurring in semiarid environments have ...

Comparing Measurements of Vascular Diameter Using Adaptative Optics Imaging and Conventional Fundus Imaging

Diagnostics, 2022
The aim of this prospective study was to compare retinal vascular diameter measurements taken from standard fundus images and adaptive optics (AO) images. We analysed retinal images of twenty healthy subjects with 45-degree funduscopic colour photographs

Xylem Vessel Diameter Affects the Compartmentalization of the Vascular Pathogen Phaeomoniella chlamydospora in Grapevine

Frontiers in Plant Science, 2017
Fungal wilt diseases are a threat to global food safety. Previous studies in perennial crops showed that xylem vessel diameter affects disease susceptibility.

Retinal Vessel Diameters and Risk of Hypertension [PDF]

Hypertension, 2006
Generalized retinal arteriolar narrowing is an important sign of systemic hypertension, and a lower arteriolar:venular diameter ratio predicts the risk of hypertension. We investigated whether this association was based on arteriolar or venular diameters or both.

Inherent variability in structural and functional traits of xylem among three hop varieties

Plant, Soil and Environment, 2013
Intervarietal differences in xylem structure could significantly affect water transport as well as vulnerability to cavitations and thus crop yield. Evaluation of crop varieties with respect to the specific traits can be thus helpful in breeding and ...
