Retinal vessel density and cognitive function in healthy older adults. [PDF]
Exp Brain ResAbstract The eye is considered a gateway to the brain, as the retina is the only tissue of the central nervous system not protected by bones. This enables non-invasive imaging to provide exceptional insights into the brain. Based on the similarity of brain and retinal structure, it is being investigated whether changes in retinal blood flow ...

Aortic valve cusp vessel density: Relationship with tissue thickness [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2002 The presence of a microvasculature within aortic cusps implies that tissue oxygen requirements exceed the amount deliverable by diffusion from the tissue surfaces alone. For the design of a successful tissue-engineered valve replacement, the effect of diffusion distance (tissue thickness) on oxygen delivery must be considered.
