Engineering functional blood vessels in vivo
… the vascular cells could readily form functional vessels in situ. Previous work in the laboratory had successfully demonstrated the formation of functional microvascular network by co-implantation of human umbilical cord vein endothelial cells (HUVECs) and 10 T 1/2 cells, a line of mouse embryonic …

Modelling of Residual Stresses of Blood Vessels
… The stress distribution over arterial walls in blood vessels is affected by residual stresses and stresses due to blood pressure. However, residual stresses are still not reliably determined. For this reason, a suitable incorporation of these stresses is required in order to establish the wall …

ENDOTHELIAL- EPITHELIAL INTERACTIONS Blood vessels friends or foes?
… which are located in the pancreas, regulate blood glucose levels. The lack of insulin production requires administration of insulin. This is accomplished by insulin injections. Even though the treatment methods have been improved, we are still not able to artificially regulate the blood …

From developmental biology to tissue-engineering: printing blood vessels
… has shown several limitations for small-diameter blood vessel tissue-engineering, evidenced by the fact that they can elicit adverse host responses and interfere with, rather than guide, direct cellcell interaction as well as assembly and alignment of cell-produced extracellular matrix. …

Noninvasive optoacoustic monitoring of blood oxygenation in large blood vessels
Continuous monitoring of cerebral blood oxygenation is critically important for successful treatment of patients with severe traumatic brain injury and patients undergoing cardiac surgery. At present, the techniques for monitoring blood oxygenation are invasive. We propose the noninvasive …

The structural and functional changes of blood vessels during aging
… and embedded in paraffin then sectioned at 51lm. Vessels were examined by microscopy and protein expression was determined by indirect immunofluorescence. The thickness of the adventitia increased dramatically with age. Immunofluorescence revealed a robust expression of endothelin system proteins …

NUMERICAL AND EXPERIMENTAL INVESTGIATION OF CRYO-FREEZING WITH LARGE BLOOD VESSELS
… The influence of heating effect due to blood flow (through the vessel surface) has been investigated by applying the boundary condition-enforced IBM. Results have indicated that the heat source term due to the blood flow in the vessel embedded in the bioheat transfer equation …

MAPK and pro-inflammatory mediators in the walls of brain blood vessels following cerebral ischemia
… stroke. Both are associated with disruption of blood flow to a part of the brain with rapid depletion of cellular energy and oxygen, resulting in ionic disturbances and eventually neuronal cell death [3]. The pathologic process that develops after stroke is divided into acute (within hours), …

Development of an ultrasonic needle guide as an aid to percutaneous puncture of blood vessels
The puncturing of blood vessels is often a "hit and miss" procedure which may take even a skilled physician considerable time to perform. Perhaps even more important than the time taken by medical personnel is the trauma inflicted on patients when the procedure is unnecessarily prolonged. A needle …

EVALUATION OF THE IMPORTANCE OF SMOOTH MUSCLE TO THE DEVELOPMENT OF FUNCTIONAL TISSUE ENGINEERED BLOOD VESSELS
Tissue engineered blood vessels (TBEV) represent an attractive method for developing arterial substitutes to address limitations in synthetic scaffolds and lack of suitable autologous vessels. Most studies to date have necessarily focused on incorporating endothelial cells (EC) for TEBV …

Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed
… and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT. Three different kinds of wounds were …
