Microbubble dynamics in microvessels: Observations of microvessel dilation, invagination and rupture
2008 IEEE Ultrasonics Symposium, 2008Understanding the interaction of acoustically activated microbubbles with small blood vessels is important for designing better imaging schemes, and for targeting and drug delivery applications. To understand the fundamental mechanisms of this interaction, high-speed microscopy was used to observe microbubble dynamics in microvessels of ex vivo rat ...

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 ...

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.

Insulin Binding to Brain Microvessels
1983Publisher Summary This chapter discusses insulin binding to brain microvessels. Insulin can increase the net uptake of glucose into brain, probably by decreasing the rate of glucose efflux. Insulin also stimulates brain glycogen synthesis and amino acid synthesis.

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.

Vasomotion of Intraradicular Microvessels in Rat
Spine, 2009This study is to investigate the changes of vasomotion of intraradicular microvessels in vivo.We have observed microvascular corrosion casts of the lumbar nerve root by scanning electron microscopy and used an immunohistochemical technique to investigate the presence and distribution of autonomic and sensory nerve in blood vessels of the nerve root.It ...

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.

Tissue engineering of perfused microvessels
Microvascular Research, 2003One major obstacle toward the creation and survival of larger, three-dimensional tissues is the lack of a vascular network that provides transport of oxygen, nutrients, and metabolic byproducts. Although attempts to create microvasculature in vitro have been described previously (Microcirculation 2 (1995), 377; Tissue Eng. 6 (2000), 105; Ann.
