http://ift.tt/2EEh8Ey As we are approaching the 100th anniversary of the discovery of insulin, a wide array of its signaling pathways has been defined. However, the initial step in insulin action, i.e. the engagement with its cell-surface receptor and the resulting conformational change, which propagates across the plasma membrane to the intracellular module, remains poorly understood.

The patient, a 36-week fetus with complete atrioventricular block and cardiac dysfunction, was at high risk of pre-term death. While attached to its mother via umbilical cord, the baby received a temporary pacemaker, which stabilized its dangerously low and irregular heart rate and ensured enough blood flow from the heart to the rest of its body for delivery.

http://ift.tt/2HkQOku Children who have heart surgery as infants are at risk for hearing loss, coupled with associated risks for language, attention and cognitive problems, by age four. In a cohort of 348 preschoolers who survived cardiac surgery, researchers found hearing loss in about 21 percent, a rate 20 times higher than is found in the general population. This underscores the importance of early hearing evaluations in young children who undergo heart surgery.
