Abstract Intraarterial infusion of potassium causes vasodilation whereas reduction of the potassium concentration in the inflowing blood causes vasoconstriction. These responses have always been puzzling since the predicted effects from the Nernst equation are just the reverse. Recent evidence suggests that they result form effects on the activity of

Blood vessels, circulation and blood pressure
Nursing Standard, 2012This article, which forms part of the life sciences series, describes the vessels of the body's blood and lymphatic circulatory systems. Blood pressure and its regulatory systems are examined. The causes and management of hypertension are also explored.

Leakage-resistant blood vessels in mice transgenically overexpressing angiopoietin-1.
Science, 1999Angiopoietin-1 (Ang1) and vascular endothelial growth factor (VEGF) are endothelial cell-specific growth factors. Direct comparison of transgenic mice overexpressing these factors in the skin revealed that the VEGF-induced blood vessels were leaky ...

Journal of the American Medical Association, 1946
Increasing emphasis placed on physiology and on biochemical methods in the training of surgeons has reduced the study of anatomy to a relatively unimportant position. No one can deny or deprecate the contributions other sciences have made to surgery, but the neglect of training in anatomy, both in graduate and undergraduate teaching, has been a ...

Clinics in Dermatology, 2011
The traditional nomenclature of vascular lesions has been enlarged and modified with the usage of newer diagnostic techniques. Digital technology has enhanced the precision of older analog tools such as Doppler flow studies. Angiograms have also more precisely delineated flow patterns to allow planned surgical intervention as an important therapeutic ...

Diseases of the Blood Vessels [PDF]
, 1991 In this chapter we will consider diseases in which malformations, functional abnormalities or inflammation of the arteries, arterioles, capillaries, venules and veins play a major role. A certain amount of overlap with other chapters is unavoidable. Some vascular malformations are considered under nevi (Chap.

The Blood Vessels of Retinoblastomas
Archives of Ophthalmology, 1961Retinoblastomas are rapidly growing malignant tumors of the retina. They arise from the nuclear layers of the retina and are, therefore, neuroectodermal in character. The characteristic growth pattern of the retinoblastomas is that the neuroectodermal tumor cells arrange themselves in lobules around many newly formed vascular channels. These arise from

Is it the blood pressure or the blood vessel?
Journal of the American Society of Hypertension, 2007The physiologic link between vascular health and arterial pressure makes it difficult to separate the adverse effects of pressure and vascular functional and structural alterations in determining the adverse complications of hypertension. Since endothelial dysfunction and nitric oxide deficiency are characteristic features of hypertension and of other ...

Laser Effects on Blood, Blood Vessels and Blood Vessel Tumors
1967Impacts of the laser on living tissue show significant effects on blood vessels with either hemorrhage or thrombosis (clotting), or both. It was assumed that the red color absorbed the laser radiation. Our studies on fresh blood smears showed destruction of red cells even with low energy densities.

Blood Vessels and Lymphatic Vessels
2019Development of the vascular and lymphatic trees is essential for the formation of nearly every organ during embryonic and fetal life. In the fetus, there are some unique features of the vascular tree that facilitate the fetoplacental circulation in utero, such as the umbilical vein, umbilical arteries, ductus venosus, and ductus arteriosus.
