Back in 2011, researchers at the Icahn School of Medicine at Mount Sinai generated some excitement in the cardiology community when they announced they had used stem cells from placenta to regenerate damaged hearts in pregnant mice. Now, they’ve taken that research a step further, isolating the precise population of cells that have that regenerative ability. The Mount Sinai team discovered that Cdx2 cells in the placenta of mice can migrate through the circulatory system and target heart injuries. Once there, the cells transform into beating heart cells and start the repair

Stroke drug cocktail normalizes brain fluids, restores movement in mice

Adrenergic receptor (AdR) antagonists work by counteracting electrical and chemical disturbances in the brain. New research in mouse models suggests that a cocktail of these drugs may reduce the spread of tissue damage and aid in recovery. Researchers led by the Riken Center for Brain Science in Japan administered AdR blockers to mice following a stroke and observed fluid in the brain, which can accumulate and lead to damaging swelling. They discovered that the drugs normalized fluid exchange and helped level out potassium in the animals’ brains. Mice that received

Following years in development, the FDA has cleared a web-based solution that uses artificial intelligence to detect and classify the sounds of potentially dangerous heart murmurs using a digital stethoscope. While physicians have been manually listening to chest and heart sounds to screen for disease for centuries, the platform developed by eMurmur allows doctors, nurses and other practitioners to employ their smartphones—allowing for greater accuracy anywhere without the need of a trained specialist. Using a third-party digital stethoscope, the recording is uploaded via the company’s mobile app to a HIPAA-compliant
