corneal new vessels can result in significant loss of vision as well as reduce graft survival. Recently, newer treatment modalities have been introduced. however, attempts to meet the challenge of evaluating corneal vessels by quantification are evolving. In vivo evaluations range from computer-aided analysis of colour images to determination of area, diameter and tortuousity of blood vessels o...

SIR,-No treatment is available for tackling the underlying cause of secondary lymphoedema due to dissection of the lymphatic pathway at a specific site.’ A bypass within the lymphatic system seems the most promising way to eliminate the cause for swollen legs in the early stages of the disease, but materials other than lymphatic collectors cannot maintain an adequate lymph flow over a long peri...

The ultrastructure of experimentally induced newly formed subretinal vessels was correlated with the amount of fluorescein leakage demonstrated by the neovascular membranes during angiography. The membranes that demonstrated leakage contained subretinal vessels with a fenestrated endothelial wall and intermediate interendothelial cell junctions. As these subretinal plexi matured, they stopped d...

Extensive experimental investigations of hydrofoil-assisted catamarans have identified the main hydrodynamic parameters affecting the performance of these vessels. Design principles of existing vessels are discussed in the light of these hydrodynamic findings. The experience gained from experimental testing has provided the basis for the development of a non-linear vortex lattice method for des...

In the present investigation vessels of 16 species of family Asclepiadaceae have been studied. Through a lot of variation exists in the size and shape of vessels, number of perforation plates and intravascular thickening of walls in the taxa, the vessels in asclepiadaceae are found highly specified.

How vessels become leaky he cremaster, an obscure muscle that keeps testicles close to the male body when cold sets in, has had two moments of glory. The more recent was at New York's Guggenheim museum in 2003, when Matthew Barney presented his full cycle of Cremaster films and associated paraphernalia. There were few if any participants in that artfest who were aware of the cremaster's earlier...

Background The role of nitric oxide (NO) in reactive hyperemia (RH) is not well known. We investigated whether NO plays a role in RH in human forearm vessels by examining the effects of N0-monomethyl-L-arginine (L-NMMA), a blocker of NO synthesis, on reactive hyperemic flow. Methods and Results Forearm blood flow (FBF) was measured by strain-gauge plethysmography with a venous occlusion techniq...

Blood vessels are the way for nutrients present outside the brain to gain access into the cerebral parenchyma. When neurons are diseased, for example by toxin exposure, reactive glial cells secrete local factors that induce microangiogenesis, probably as part of a spontaneous neuroprotective mechanism related to the increased metabolic demand. In Parkinson's disease (PD) and non human primate m...

Background Dynamic gadolinium contrast-enhanced (DCE) vessel wall MRI has recently been used to compute a set of model-based contrast kinetic parameters (e.g. K and Vp) that can well characterize the extent of inflammation in carotid plaques [1,2]. However, no studies have shown its feasibility in coronary artery wall, presumably due to the technical challenges in imaging such a constantly-movi...
