Acute thrombosis of an abdominal aortic aneurysm following intra-aortic balloon pumping.
Acute thrombosis of an abdominal aortic aneurysm is a rare but devastating surgical emergency. We present the first case of a patient with sudden thrombosis of an AAA delayed (more than 24 h) after removal of an intra-aortic balloon pump. Treatment options include open surgical repair, axillobifemoral grafting or endovascular aortic repair. The patient received an aorto-bifemoral graft. The ass...
متن کاملOptical Pumping
T he rather odd term optical pumping means just what it says. In general “pumping” is a process of raising matter from lower to higher energy; for example, raising the potential energy of water hy moving it from an underground well to an elevated tank. In this article we shall he concerned w i t h the pumping of individual atoms from lower to higher states of internal energy. The word optical r...
متن کاملOptical Pumping
Optical pumping uses light to affect the internal degrees of freedom of a sample of atoms in a vapor. These internal degrees of freedom are angular momentum states of the atomic ground state, which are populated when light is absorbed and emitted. This experiment reveals many phenomena of quantum mechanics including angular momentum selection rules, the density matrix, and resonance. Optical pu...

The primary role of the ZIP13 metal transporter in flies is to move iron ions out of cells, rather than moving zinc ions into cells, as is the case in human cells.
متن کاملFunctional characterization of sodium-pumping rhodopsins with different pumping properties
Sodium pumping rhodopsins (NaRs) are a unique member of the microbial-type I rhodopsin family which actively transport Na+ and H+ depending on ionic condition. In this study, we surveyed 12 different NaRs from various sources of eubacteria for their electrophysiological as well as spectroscopic properties. In mammalian cells several of these NaRs exhibited a Na+ based pump photocurrent and four...
