Research team pairs 3-D bioprinting and computer modeling to examine cancer spread in blood vessels

Lawrence Livermore National Laboratory (LLNL) scientists have paired 3-D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis. The unique approach, developed with outside collaborators, lays the foundation for developing a predictive capability that can help

Researchers identify ‘hot spots’ for developing lymphatic vessels

When an embryo develops, a wide variety of proteins and enzymes trigger a series of biochemical reactions. The development of the lymphatic vasculature is crucially dependent on one specific protein—the growth factor VEGF-C. In order to become biologically active and to initiate downstream signaling events, the protein must first undergo processing steps. Thus far it

OCT Imaging Needle Can Detect Blood Vessels in Neurosurgery

THURSDAY, Dec. 20, 2018 — A miniaturized optical coherence tomography (OCT) imaging needle can detect blood vessels intraoperatively in the human brain in vivo, according to a study published online Dec. 19 in Science Advances. Hari Ramakonar, M.B.B.S., from Sir Charles Gairdner Hospital in Nedlands, Australia, and colleagues developed an imaging needle that is able

What hookah smoking can do to your blood vessels

More and more people are giving up smoking, and they are sensible to do so. Cigarette smoking is “the leading preventable cause of death in the United States,” according to the Centers for Disease Control and Prevention (CDC), with cigarettes causing over 480,000 yearly deaths. However, as the use of regular cigarettes is declining, more

Cancer drug helps treat tuberculosis by restoring leaky blood vessels

Biomedical engineers have discovered an unlikely potential ally in the global fight against tuberculosis—an FDA-approved drug originally designed to treat cancer. Matrix metalloproteinases (MMPs) are naturally produced by animals to break down connective tissue for a wide array of biological processes such as wound repair, growth and tissue development. Many diseases, however, can hijack these
