However, they all keep cerebral veins and venules at an arm's length.
Originally, it was thought appropriate to quantify generalised arteriolar attenuation due to evidence that arterioles would be more affected by narrowing in response to cardiovascular disease processes than venules. (12,14) Subsequently, this approach was used in a number of large community-based epidemiology studies such as ARIC, Blue Mountain Eye Study (BMES), Wisconsin Epidemiologic Study of Diabetic Retinopathy, Cardiovascular Healthy Study, Beaver Dam Eye Study (BDES) and the Rotterdam Study.
In the preliminary examination of 10 cases, double staining with factor VIII and EVG (Figure 3) was considered the most appropriate to identify the vessels, distinguishing at the same time arterioles and venules. Therefore all cases were evaluated based on this staining.
Peritoneal rupture of the cyst did not occur in our case but the hydatid protoscolex found within a hepatic venule (Figures 4&5) indicates that the patient had intravascular exposure to the parasite.
At sites of acute inflammation, circulating neutrophils emigrate from the blood stream into the extravascular tissues through the postcapillary venules. The migration of leukocytes from the blood to sites of extravascular injury is mediated through a sequential cascade of leukocyte-endothelial cell adhesive interactions which involve an array of cell adhesion molecules (CAMs) present on leukocytes and endothelial cells.
Having a fever affects "gatekeeper" cells called high endothelial venule cells, or HEVs, which "invite" the lymphocytes in.

These results support our findings of increased WLR and no changes in venule parameters in patients with IGT compared to age-matched healthy controls.
Correlations were found between the BFVs of the 20- and 35-degree FOVs (arteriole: r = 0.83, P = 0.002; venule: r = 0.69, P <0.001, Figure 3).
