by University of Strathclyde, Glasgow Credit: CC0 Public Domain An invisible lining of blood vessels uses a vast network of connections to control all cardiovascular functions and the risk of developing cardiovascular disease. Cardiovascular disease is a group of conditions that can arise from a lack of physical activity, poor diet, or certain disorders. Scientists...
EUROPEAN ASSOCIATION FOR THE STUDY OF OBESITY A new study being presented at the European Congress on Obesity (ECO) in Maastricht, the Netherlands (4-7 May), has linked key nutrients, including protein, zinc and niacin, to improvements in heart health. Improvements in metabolic and cardiovascular health seen during weight loss in people with obesity are traditionally...
An international team that includes University of Manchester scientists has demonstrated that nerve signals are exchanged between clogged-up arteries and the brain for the first time. The discovery of the previously unknown electrical circuit is a breakthrough in our understanding of atherosclerosis, a potentially deadly disease where plaques form on the innermost layer of arteries. The mice...

The study, published...
An implant little bigger than a grain of rice, but gently in place alongside a strategically placed blood vessel, could replace much bulkier devices that stimulate nerves. Rice University engineers in collaboration with a host of Texas Medical Center institutions have published the first proof-of-concept results from a year-long program to develop tiny, wireless devices that...
by University of Oslo Earlier research has shown that several of the same risk factors behind the development of cardiovascular disease also can lead to Alzheimer’s. Pictured left to right: Shreyas B. Rao, Reidun Torp and Gry H.E. Syverstad Skaaraas. Credit: Carina Knudsen, UiO If the blood supply to your brain decreases, it can trigger...

CREDIT: CREDIT: JOHNS HOPKINS MEDICINE Johns Hopkins Medicine researchers have developed and tested a new imaging approach they say will accelerate imaging-based research in the lab by allowing investigators to capture images of blood vessels at different...
by Indiana University School of Medicine Credit: Pixabay/CC0 Public Domain A study led by Indiana University School of Medicine is challenging standard treatment methods used to prevent muscle damage during heart attack. In a paper published in the Journal of the American College of Cardiology, Rohan Dharmakumar, Ph.D. asserts that a common treatment given to patients experiencing heart attack may...
A few strategies offer the possibility of growing additional redundant blood vessels, though this is far from rigorously proven. Intermittently provoking hematopoietic stem cells to leave the bone marrow via CXCL12 upregulation, for example. Humans are not completely uniform in their major blood vessel networks, there are variant populations with more redundancy. The value of that greater redundancy is...
