MEDGADGET EDITORSMATERIALS, MEDICINE, NANOMEDICINE, NEUROLOGY, NEUROSURGERY The blood-brain barrier is nearly impenetrable to most drugs and contrast agents, making it difficult to diagnose and treat diseases afflicting the brain. Researchers at the Max Planck Institute for Polymer Research have now developed a way of using nanodiamonds coated with a biopolymer to penetrate through the blood-brain...

E-cigarettes change blood vessels after just one use, study says
By Michael Nedelman, CNN (CNN)A new study is the latest to show changes in cardiovascular function after vaping e-liquids, though in this case, those liquids didn’t even contain nicotine. The study, published Tuesday in the journal Radiology, concluded that vaping temporarily impacts blood vessel function in healthy people. Using MRI scans, it found, for example,...

By disabling a protein in the brain’s blood vessels, researchers ease age-related deterioration in mice
By ANDREW JOSEPH @DrewQJoseph Scientists have shown that delivering blood from an old mouse into a young mouse or vice versa prompts a sort of “Freaky Friday” effect: The brains of the young mice exposed to the old blood lose vitality, while the young blood rejuvenates some brain function in the older mice. What they don’t know,...

Lab-grown blood vessels provide hope for dialysis patients
By Kate Bass, B.Sc.Reviewed by Kate Anderton, B.Sc. Research published this week describes how lab-grown blood vessels were transformed into living tissue when grafted into dialysis patients needing replacement blood vessels. The recipients’ cells effectively infiltrated the artificial blood vessels, so they became like the patients’ native blood vessels. There are many conditions for which...

Creating blood vessels on demand
by Albert Ludwigs University of Freiburg When organs or tissues are damaged, new blood vessels must form as they play a vital role in bringing nutrients and eliminating waste and it is necessary for organs and tissues to regain their normal function. At present, the injection of growth factors or genetic material into the tissue site of interest can...

Scientists find key to regenerating blood vessels
Lake Nona, Fla., November 23, 2017 – A new study led by researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) identifies a signaling pathway that is essential for angiogenesis, the growth of new blood vessels from pre-existing vessels. The findings, published in Nature Communications, may improve current strategies to improve blood flow in ischemic tissue,...

Team discovers neural stem cells can become blood vessels
Professor Ricardo Pardal and his team. Mother cells from the adult carotid body can transform into blood vessels as well as neurons. This discovery could have important repercussions on the treatment of such diseases as pediatric tumors and Parkinson’s. Researchers from the University of Seville and the Seville Institute of Biomedicine (IBiS) have just...
