Training model for microvessel anastomosis
Microsurgery, 1994AbstractIn the early stages of microsurgical training a model is required which is accessible, inexpensive, and approximates human tissue. In this research centre initial training exercises utilize cold stored vessels harvested from sacrificed animals used in other experiments.

Collagen of brain microvessel preparations
Microvascular Research, 1982Abstract The collagen in rabbit brain microvessel preparations has been quantitated and partially characterized. Pancreatic elastase is employed to isolate an enriched insoluble collagen fraction. Approximately half of the collagen (as measured by the hydroxyproline content) in the microvessel preparations is associated with striated collagen fibers.

The distensibility of mesenteric venous microvessels
Pfl�gers Archiv European Journal of Physiology, 1971In 20 experiments the distensibility characteristics of venous microvessels of 22–148 μm internal diameter in response to arterial and venous pressure changes were examined microphotographically in the isolated and perfused mesentery of the dog. Over a range of arterial pressure between 0 and 170 mm Hg venular diameter changed by 31,8±8,8% and venular ...

Microvessel density in prostatic hyperplasia
BJU International, 2000Objectives To examine the prostates from patients with haematuria associated with benign prostatic hyperplasia (BPH) to determine their microvascular anatomy and thus assess histopathological differences in patients with significant haematuria.

A piezoelectric probe for microvessel occlusion
Microvascular Research, 1978Abstract The construction of a piezoelectrically actuated microprobe and control unit is described. With its aid a glass microneedle may be used for the near-instantaneous occlusion of microvessels. The movement of the microneedle may be preset. The microneedle may also be moved in a slow, finely controlled manner.

Leukocyte adhesion and microvessel permeability
American Journal of Physiology-Heart and Circulatory Physiology, 2000To investigate the direct effect of leukocyte adherence to microvessel walls on microvessel permeability, we developed a method to measure changes in hydraulic conductivity ( Lp) before and after leukocyte adhesion in individually perfused venular microvessels in frog mesentery.

The Cerebral Microvessels in Culture, an Update
Journal of Neurochemistry, 1992Abstract: Recent advances in our knowledge of the blood–brain barrier (BBB) have in part been made by studying the properties and function of cerebral endothelial cells in vitro. After an era of working with a fraction, enriched in cerebral microvessels by centrifugation, the next generation of in vitro BBB model systems was introduced, when the ...

Retinal microvessels express less gamma-glutamyl transpeptidase than brain microvessels
Current Eye Research, 1992In this investigation we localized and compared the level of gamma-glutamyl transpeptidase (GGTP) activity in retinal and brain preparations using histochemical, enzymatic and in situ hybridization assays. We compared GGTP distribution to another microvessel specific enzyme, alkaline phosphatase (AP).

Microvessel Remodeling in Cerebral Ischemia
2008The neurovascular (NV) unit, broadly defined as a segment of brain vasculature, is composed of functionally integrated cellular (including brain endothelial cells, astrocytes, pericytes, and smooth muscle cells) and acellular elements that form the basement membrane. Brain insults or conditions characterized by tissue hypoxia induce dramatic changes in

TGF-β and microvessel homeostasis
Microvascular Research, 2010Aberrant transforming growth factor-beta (TGF-beta) signaling plays a clear role in a number of pathologies, in particular, fibrotic diseases and cancer. Accumulating evidence also suggests that TGF-beta is required for vascular homeostasis, shedding light on the role of circulating TGF-beta and the expression of TGF-beta receptors in the adult ...
