In a show piece for electron microscopy (EM), Tilley at al. used single-particle cryo-EM to visualize the structural rearrangements in the bacterial toxin pneumolysin that occur when it assembles into a membrane-associated prepore and when the prepore subsequently transitions into a fully membrane-inserted pore.

The Sonic Flashlight is an ultrasound (US) device that projects real-time US images into patients with use of a semireflective/transparent mirror. The present study evaluated the feasibility of use of the Sonic Flashlight for clinical peripherally inserted central catheter placements, originally with the mirror located inside a sterile cover (n = 15), then with the mirror outside (n = 11). Succ...

Covenant Healthcare System is a 500-bed facility in Saginaw, Michigan. A peripherally inserted central catheter (PICC) program was instituted there in 1990 when it was St. Lukes Hospital. Over the course of 17 years, 30 nurses had been trained to place PICCs in their spare time. A "PICC, stick, and run team" was established in 1998 but was unsuccessful. After a merger with Saginaw General Hospi...

We suggest that magnetic fields in the accretion disks of AGN reach into the coronae above and have a profound effect on the mass flow rate in the corona. This strongly affects the location where the accretion flow changes from a geometrically thin disk to a pure vertically extended coronal or advection-dominated accretion flow (ADAF). We show that this can explain the different disk truncation...
