Blood vessels are constructed by two processes: vasculogenesis, whereby a primitive vascular network is established during embryogenesis from multipotential mesenchymal progenitors, and angiogenesis, in which preexisting vessels (both in embryo and adult) send out capillary sprouts to produce new vessels (1-3). Endothelial cells are centrally involved in each process: They migrate and prolifera...

BACKGROUND The vascular system of leiomyomata, the most common benign tumours in women, is an important factor controlling development and growth of the tumour. It has not been, however, investigated morphologically using the best currently available technique, corrosion casting combined with scanning electron microscopy. METHODS Myomatous uteri collected upon autopsy were perfused via affere...

We investigate if Marine Stewardship Council (MSC) certified Norway lobster fishing vessels in Sweden got higher prices and sold larger quantities after certification was introduced 2015. Using detailed daily panel data exploiting the fact that same water contains both non-certified vessels, we use a difference-in-difference model for analysing demand effects of MSC-certification. find price pr...

A large facial vascular malformation was embolized with polyvinyl alcohol particles twice in 8 years. Resected tissue enabled long-term examination of this material, confirming its chemical inertness and revealing minimal tissue reaction to it apart from calcification. No particle migration, fragmentation, or absorption occurred. There was some recanalization of occluded vessels. Most vessels c...

The goal of this paper is to investigate the validity a hybrid embedded/homogenized in-silico approach for modeling perfusion through solid tumors. rationale behind novel idea that only larger blood vessels have be explicitly resolved while smaller scales vasculature are homogenized. As opposed typical discrete or fully-resolved 1D-3D models, required data can obtained with in-vivo imaging tech...

The role of smooth muscle cell hypertrophy, hyperploidy, and hyperplasia in medial hypertrophy of mesenteric resistance vessels of 107- to 111-day-old spontaneously hypertensive rats (SHR) was examined using a combination of morphometric, biochemical, and immunological techniques. Mesenteric arteries were classified on the basis of branching order for comparative purposes. Branch level I vessel...

In this study, anti–basic fibroblast growth factor (anti-bFGF) antibody was used to determine whether the mitogenic effect of angiotensin II in vivo could be blocked by neutralizing bFGF in the vessel wall. Animals, divided into six experimental groups, were given (1) angiotensin II, (2) angiotensin II1anti-bFGF antibody, (3) angiotensin II1normal goat IgG (ngIgG), (4) anti-bFGF antibody, (5) n...

Animals, divided into six experimental groups, were given (1) angiotensin II, (2) angiotensin II + anti-bFGF antibody, (3) angiotensin II + normal goat IgG (ngIgG), (4) anti-bFGF antibody, (...

The coronary vasculature has been traditionally divided into three functional groups: large conductance vessels visible on coronary angiography, which offer little resistance to blood flow; small resistance vessels ranging in size from about 250 to 10 μm in diameter; and veins. Although it has been taught that arterioles (precapillary vessels < 50 μm) account for most of the coronary resistance...

Intrabronchial insufflation of acid causes immediate necrosis of the walls of many alveoli. Thrombosis of the alveolar vessels is an associated phenomenon. When a large number of vessels becomes affected, a clot propagates rapidly into the larger supplying vessels. The resulting lesion is indistinguishable from a hemorrhagic infarct. The infarct-like areas so frequently encountered in influenza...
