Probing the role of an inflammation resolution sensor in obesity and heart failure

20.11.2019 Health Problems

After heart attack injury, several fatty-acid-derived bioactive molecules—including one called resolvin D1—play an essential signaling role to safely clear inflammation and help repair heart muscle. The mechanism of how this resolution occurs is not well-understood. There is a receptor on the surface of many immune cells called ALX/FRP2, and in models of atherosclerosis, ALX/FPR2 is known to act as a […]

New MRI sensor can image activity deep within the brain

22.02.2019 Health Problems

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain. MIT researchers have now devised a new way to image calcium activity that is based on magnetic resonance […]

Engineers create delicate sensor to monitor heart cells with minimal disruption

02.01.2019 Health Problems

For the first time, engineers have demonstrated an electronic device to monitor beating heart cells without affecting their behavior. A collaboration between the University of Tokyo, Tokyo Women’s Medical University and RIKEN in Japan produced a functional sample of heart cells with a soft nanomesh sensor in direct contact with the tissue. This device could aid study of other cells, […]
