This process establishes the coronary vasculature that nourishes the heart muscle. Credit: Max Delbrück CenterA team led by Dr. Elena Cano in the Integrative Vascular Biology Lab...
by Bob Yirka , Medical Xpress Helical mCR with articulated magnetic tip. (A) The helical protrusion on the outer surface of the continuum robot, upon rotation, pushes the robot tip forward. (B) The segmented articulating magnetic tip increases the magnetic volume and decreases bending stiffness for improved steerability. (C) The helical robot prevents buckling and...
UNIVERSITAT OBERTA DE CATALUNYA (UOC) A high level of carotenes in the blood is linked with a lower degree of atherosclerosis in the arteries and thus a lower risk of cardiovascular diseases. These are the conclusions of a new study by a team of researchers from IDIBAPS and the UOC, published as open access in Clinical Nutrition. The...
by Barbara Branning, University at Buffalo A study by a University at Buffalo investigator sheds new light on the link between early COVID-19 symptoms and eventual positive test results. The research could lead to new protocols for determining who will be tested and how best to use testing resources. One compelling finding of the study...
CREDIT: COPYRIGHT UC REGENTS/UC DAVIS HEALTH A protein known to expand blood vessels — key to controlling conditions like high blood pressure — actually has different functions in males and females, new UC Davis Health research shows. Conducted using arterial cells from mice, the study is the first to identify sex-based distinctions in how the...
by Harvard Medical School The brain is a ravenous organ. A three-pound adult human brain consumes about a fifth of the body’s energy, yet it cannot store energy on its own and requires constant nourishment from the cardiovascular system. The organ’s energy needs fluctuate greatly depending on neural activity, and sufficient blood must be delivered...
A new clinical trial to study a potential way of reducing the risk of early-onset atherosclerosis may be on the way. After evaluating previous research, a report published in the Journal of the American Heart Association concludes that a clinical trial might pave the way for a new treatment to help reduce the early onset...
Bananas and avocados — foods that are rich in potassium — may help protect against pathogenic vascular calcification, also known as hardening of the arteries. University of Alabama at Birmingham researchers have shown, for the first time, that reduced dietary potassium promotes elevated aortic stiffness in a mouse model, as compared with normal-potassium-fed mice. Such arterial...
A certain immune reaction is the key, not to slowing atherosclerosis like cholesterol-lowering drugs do, but instead to reversing a disease that gradually blocks arteries to cause heart attacks and strokes. This is the finding of a study in mice led by researchers at NYU Langone Medical Center and published online June 26 in the Journal...
