Intussusception is relatively uncommon, occurring in 0.5 to 2.3 cases per 1,000 live births in the USA. Radiology residents, therefore, have few opportunities to participate in intussusception reduction during training, and practicing radiologists encounter it infrequently. Training is essential, as successful reduction avoids surgery. The judgment involved(More)
Na(+)-K(+)-ATPase (NKA) establishes the transmembrane [Na(+)] gradient in cells. In heart, phospholemman (PLM) inhibits NKA activity by reducing its apparent Na(+) affinity, an effect that is relieved by PLM phosphorylation. The NKA crystal structure suggests regions of PLM-NKA interaction, but the sites important for functional effects in live cells are(More)
