Can non-contact SIAscopy be used in the diagnosis and quantification of pigmentary skin changes associated with photodamage?
… dyspigmentation, sallowness, erythema and vessel dilation. Relevant features were isolated and the relationship with age was determined using linear regression. From this a predictive skin photodamage age was generated and tested with a sample set of images. Conclusions Specific pigmentary …

Notch deficiency leads to arteriovenous malformations and altered pericyte function
During angiogenesis, nascent blood vessels sprout from pre-existing vasculature and recruit pericytes to induce maturation and vessel quiescence. Perictyes are associated with small vessels and capillaries where they share the basement membrane with the endothelium to provide vascular support. …

The hemo-neural hypothesis : effects of vasodilation on astrocytes in mammalian neocortex
… astrocytic endfeet ensheathe cerebral blood vessels, which change size in order to regulate blood flow. We found that changes in local biophysical state caused by mechanical perturbations exerted through blood vessels can depolarize astrocytes and some neurons in slice. To test the hemoneural …

Nitric Oxide Bioavailability Regulation by Hemoglobin
… transductor. NO plays an important role in the dilation of blood vessels. It is produced in the endothelial cells which line the inside of blood vessel walls. Smooth muscle tissue, which completely surrounds blood vessels, can tense (contract) or relax to decrease or increase the diameter of a …

Mathematical Models of Major Arterial Occlusion
… that occur on different time scales, namely vessel dilation and constriction on a short time scale and structural changes including arteriogenesis and angiogenesis on a long time scale. In the acute time frame, the responses that contribute most to changes in vascular tone are increases in …

Relationships between subtle ocular changes and microvascular complications in people with type 2 diabetes
… CV). Other ocular biomarkers (retinal vessel diameters and their ratio, retinal vessel oxygenation, thickness of retinal layers, and flicker induced vasodilation (FIV) were also utilised. 2) Clinical study: participants attending the research centre underwent ocular testing forming a …

No-Independent Modulation of Soluble Guanylyl Cyclase (Sgc) Activity and Function
<p>Soluble guanylyl cyclase (sGC) plays a key role in the nitric oxide (NO) signaling pathway, where it functions as an NO receptor and generator of a secondary intracellular messenger, cGMP. In addition to NO, investigators have identified a number of proteins that interact with sGC and modulate …
