By Ben Coxworth n this X-ray image, one of the millirobots (bright spot at center right) can be seen making its way through a blood vessel connecting two kidneys and an aortaUniversity of Twente While some blood clots can be removed via a flexible tool that’s inserted into the affected vein or artery, others are much...
by University of California, Irvine t-BHP-treated RBC stall in cerebral blood vessels and impair cerebral blood flow velocity shown by in vivo high-resolution two-photon imaging in mice. Schematic of the experimental design (A). RBC were collected from FVB/NJ mice, treated with control PBS or the oxidative stressor t-BHP, then labeled with the PKH26 fluorescent dye...
by Josh Barney, University of Virginia UVA researchers say they have found a biological process that contributes to the disease and may be a target for life-saving therapies. Credit: Emily Faith Morgan, University Communications University of Virginia Health researchers probing the causes of coronary artery disease have identified critical biological processes that can go wrong inside the linings of blood...
by Brown University In stunning detail, Brown engineer Jonghwan Lee can use retinal scanning technology to image the vasculature of neural tissue. Credit: Jonghwan Lee While age-related brain disorders like Alzheimer’s disease often develop slowly across an individual’s lifetime, they usually aren’t detected until symptoms have already started. With that in mind, teams of biomedical researchers led by...
MICHELLE HAMPSON 07 MAR 20233 MIN READ SCIENCE PHOTO LIBRARY/GETTY IMAGES JOURNAL This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. When a patient has a blocked artery or blood vessel, a team of surgeons must carefully thread an ultrathin catheter through the person’s blood vessel to reach the lesion...
by Indiana University School of Medicine Credit: Pixabay/CC0 Public Domain Researchers from the Indiana Center for Regenerative Medicine and Engineering (ICRME) have identified a new type of cell in the human and mouse body, called the vasculogenic fibroblast, that provides critical insight into how new blood vessels can be made when needed for treatment. Blood...

NOVEMBER 7TH, 2022 CONN HASTINGSCARDIAC SURGERY, MATERIALS, PEDIATRICS, SURGERY, THORACIC SURGERY, VASCULAR SURGERY Researchers at the University of Sydney in Australia have developed an electrospun blood vessel replacement. The material contains tropoelastin, a natural precursor for elastin, a key component of blood vessel walls. Elastin is present in concentric circles in natural blood vessels and...
