Vascular patterning and leaf shape
Current Opinion in Plant Biology, 2001Morphogenesis of leaf shape and formation of the major elements of leaf vasculature are temporally coordinated during leaf development. Current analyses of mutant phenotypes provide strong support for the role of auxin signaling in vascular pattern formation and indicate that leaf shape and vasculature are developmentally coupled.

Practice Patterns of Vascular Surgery's "1%"
Annals of Vascular Surgery, 2020Public focus on health care spending has increased attention on variation in practice patterns and overutilization of high-cost services. Mainstream news reports have revealed that a small number of providers account for a disproportionate amount of total Medicare payments.

Assessment of Vascular Patterning in the Zebrafish
2020The zebrafish has emerged as a valuable and important model organism for studying vascular development and vascular biology. Here, we discuss some of the approaches used to study vessels in fish, including loss-of-function tools such as morpholinos and genetic mutants, along with methods and considerations for assessing vascular phenotypes.

Choroidal Vascular Patterns in Hypertension
Archives of Ophthalmology, 1964In a previous paper 1 we presented observations on senile vascular patterns of the choroid and their relationship to drusen. The choroidal vessels were prepared in a manner which made possible the simultaneous study, on the flat, of the vessel patterns, of the cells of the vessel wall and of Bruch's membrane.

Vascular Pattern Formation in Plants
2010Reticulate tissue systems exist in most multicellular organisms, and the principles underlying the formation of cellular networks have fascinated philosophers, mathematicians, and biologists for centuries. In particular, the beautiful and varied arrangements of vascular tissues in plants have intrigued mankind since antiquity, yet the organizing ...

Vascular pattern in the pancreas of the cat
Cell and Tissue Research, 1982The pathways of microcirculation in the pancreas of the cat were investigated by scanning electron microscopy of Mercox preparations of the vascular bed. A portal system from islet to exocrine vessels as well as a direct arterial flow to the exocrine pancreas have been observed. Sphincters appear to exist in portal capillaries at the border between the

THERMOGRAPHIC PATTERNS IN PULMONARY VASCULAR DISEASE
The Lancet, 1969Abstract Encapsulated liquid crystals on black mylar sheets were used to map out thoracic thermographic patterns at the bedside. In two patients with acute pulmonary thromboembolism, and in one with chronic pulmonary vascular disease, cool patches of skin were demonstrable over the affected pulmonary segments. The results of thermographic localisation

Archives of Ophthalmology, 1961
It is generally held that microaneurysms constitute the characteristic lesion of diabetic retinopathy. First observed by MacKenzie and Nettleship in 1879, 1 the microaneurysms were rediscovered by Ballantyne and Loewenstein in 1943 2 and have been described by numerous clinicians and pathologists since that time.

Vascular patterns in skin tumors
Clinics in Dermatology, 2002Dermoscopic analysis of skin tumors in the past has mainly focused on pigmented structures. Features of vascularization received surprisingly little interest, although in the clinical diagnosis, one of the clues for basal-cell carcinoma (BCC) is the visible presence of blood vessels (telangiectasia).

Segmental Vascular Patterns of the Choriocapillaris
American Journal of Ophthalmology, 1975I investigated the vascular architecture of the peripheral choriocapillaris in the eyes at autopsy, utilizing the histochemical alkaline phosphatase reaction. There was a segmental distribution of the capillaries, with the feeding arterioles at the periphery and the draining venule in the center of capillary lobules. These findings support the clinical
