Earlier blood transfusion reduces heart complications post-surgery in high-risk patients

An earlier blood transfusion- done when hemoglobin levels were higher - after major general or vascular surgery among people with heart disease was associated with a lower risk of some complications but not the most severe ones, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

UIC researchers discover an important cellular mechanism that drives aging

As our hairs go gray and our muscles weaken with age, our immune system also changes. In particular, the stem cells that become blood or immune cells can develop mutations, potentially leading to cancers or other dysfunctions.

New research brings safer artificial hearts closer to clinical use

Using magnetic cameras, researchers at Linköping University have examined blood flow in an artificial heart in real time. The results make it possible to design the heart in a way to reduce the risk of blood clots and red blood cells breakdown, a common problem in today's artificial hearts.

Hemoglobin emerges as a natural antioxidant defense in the brain

Did you know the same protein that gives blood its red color and carries oxygen throughout the body is also present inside brain cells? Hemoglobin, long celebrated for ferrying oxygen in red blood cells, has now been revealed to play an overlooked - and potentially game-changing - antioxidant role in the brain.
