Automated measurements of retinal bifurcations [PDF]

, 2009
This paper presents an analysis of the bifurcations of retinal vessels. The angles and relative diameters of blood vessels in 230 bifurcations were measured using a new automated procedure, and used to calculate the values of several features with known ...

Neurenteric Cysts Found on the Outer Membrane of a Subdural Haematoma

Case Reports in Neurological Medicine, 2013
We report on a patient initially diagnosed with a chronic subdural haematoma that was resistant to treatment. After the second burr hole craniostomy within a half month failed to resolve the subdural haematoma (SDH), we performed a craniotomy to identify

A deep learning approach to 3D segmentation of brain vasculature [PDF]

, 2019
The segmentation of blood-vessels is an important preprocessing step for the quantitative analysis of brain vasculature. We approach the segmentation task for two-photon brain angiograms using a fully convolutional 3D deep neural network.Published ...

Systematic in vitro comparison of decellularization protocols for blood vessels

PLoS ONE, 2018
Decellularization of native blood vessels is a promising technology to generate 3D biological scaffolds for vascular grafting. Blood vessel decellularization has been performed in previous studies under various experimental conditions, that complicates ...

Arrival time mapping with 15O-gas PET for cerebrovascular steno-occlusive diseases: a comparative study with CT perfusion

EJNMMI Research
Background Positron emission tomography (PET) with 15O-gas for quantifying cerebral blood flow (CBF) and oxygen metabolism is the gold standard for assessing hemodynamics in ischemic cerebrovascular disease.

In-depth proteomics identifies a role for autophagy in controlling reactive oxygen species mediated endothelial permeability [PDF]

, 2016
Endothelial cells (ECs) form the inner layer of blood vessels and physically separate the blood from the surrounding tissue. To support tissues with nutrients and oxygen, the endothelial monolayer is semipermeable.

Visualization of tumor-related blood vessels in human breast by photoacoustic imaging system with a hemispherical detector array

Scientific Reports, 2017
Noninvasive measurement of the distribution and oxygenation state of hemoglobin (Hb) inside the tissue is strongly required to analyze the tumor-associated vasculatures.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Inter-individual variability in the relationship between propulsion force and walking speed in subacute stroke

Scientific Reports
Walking speed is primarily driven by the propulsion force generated during the late stance phase, but the translation of propulsion force to walking speed may differ across individuals.
