Fat Around Arteries May Be Good For Health

New York: Researchers have found that fat around our arteries may play an important role in keeping those blood vessels healthy. The fat, known as perivascular adipose tissue, or PVAT, helps arteries do what scientists call “stress relax,” or let go of muscular tension while under constant strain. This is similar to the bladder, which […]

Tiny robotic thread can slip through brain's blood vessels

Washington: Researchers have developed a magnetically steerable, thread-like robot that may actively glide through narrow, winding pathways like the brain’s tiny blood vessels. The study, published in the journal Science Robotics, revealed that the magnetically controlled device could one day deliver clot-reducing therapies in response to strokes or other brain blockages, Xinhua reported. “If acute […]

These tiny swimming robots may deliver drugs in blood vessels

London: Scientists have developed tiny elastic robots that can change shape depending on their surroundings and can swim through fluids, an advance which may help deliver drugs to diseased tissue one day. The smart, biocompatible microrobots that are highly flexible are made of hydrogel nanocomposites that contain magnetic nanoparticles allowing them to be controlled via […]

Researchers develop new method to grow blood vessels

New York: Researchers, including one of Indian-origin, have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels. The formation of new blood vessels — a process also known as angiogenesis — is one of the major clinical challenges in wound healing and tissue implants. The […]
