Scientists have discovered that red blood cells act as hidden glucose sponges in low-oxygen conditions, explaining why people ...

Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's ...

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one ...

Hypoxic conditions trigger red blood cells to absorb and utilize more glucose, reducing blood sugar and offering a potential therapy to control diabetes.

A rare physiological case study shows how aerobic capacity, muscle adaptation, and oxygen use can remain remarkably intact well into the eighties.
