Scientific collaborators from Yale School of Medicine and University College London (UCL) have uncovered the molecular pathway by which new arteries may form after heart attacks, strokes and other acute illnesses bypassing arteries that are blocked. Their study appears in the April 29 issue of Developmental Cell. Arteries form in utero and during development, but can also form in adults when organs become deprived of oxygen – for example, after a heart attack. The organs release a...

How Blood Vessels Regroup After Stroke
2013-02-11 10:53:18

Rice University [ Watch The Video ] By thinking of cells as programmable robots, researchers at Rice University hope to someday direct how they grow into the tiny blood vessels that feed the brain and help people regain functions lost to stroke and disease. Rice bioengineer Amina Qutub and her colleagues simulate patterns of microvasculature cell growth and compare the results with real networks grown in their lab. Eventually, they want to develop the ability to control the way...

Blood vessel permeabilty Dr. Jean-Philippe Gratton, Director of the Endothelial cell biology research unit at the Institut de recherches cliniques de Montr©al (IRCM), identifies a new intracellular mechanism responsible for modulating vascular permeability: the nitrosylation of beta-catenin protein by nitric oxide. This scientific breakthrough could have a possible impact on the treatment of cancerous tumours by altering the permeability of the blood vessels irrigating them. Dr....

  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
