Owning our off-ramps
In this issue of JCHIMP, Meade et al., publish the results of qualitative analysis regarding a second-year rotation in tracing the outcome of discharged patients. They report that their residents develop remarkable insights into the types of failures and miscommunications that plague our discharge processes. This perspective piece places this article in the context of literature seeking to unde...
متن کاملPaul I. Terasaki, PhD, 1929-2016.
Paul Terasaki was a pioneer of transplantation and had a global following. His career, which spanned >50 years, included accomplishments and discoveries that revolutionized the field of transplantation and that advanced the care of transplant patients. Paul is survived by his wife Hisako, his brother, four children and six grandchildren as well as legions of close friends and colleagues around ...
متن کاملSingle-Shot Diffusion-Weighted Spiral Imaging
Introduction: Spiral trajectories offer a range of desirable properties: short echo times, high SNR efficiency, a uniform point-spread function and a well-conditioned reconstruction problem for high reduction factors in parallel imaging, such as with circular coil-arrays as employed for head MRI. In diffusion weighted MRI (DWI), single-shot spiral imaging could increase the achievable SNR while...
متن کاملIntracellular transport by active diffusion.
All substances exhibit constant random motion at the microscopic scale. This is a direct consequence of thermal agitation, and leads to diffusion of molecules and small particles in a liquid. In addition to this nondirected motion, living cells also use active transport mechanisms, such as motor activity and polymerization forces that depend on linear biopolymers and are therefore fundamentally...
متن کاملIntracellular facilitated diffusion: searchers, crowders, and blockers.
In bacteria, regulatory proteins search for a specific DNA-binding target via "facilitated diffusion": a series of rounds of three-dimensional diffusion in the cytoplasm, and one-dimensional (1D) linear diffusion along the DNA contour. Using large scale Brownian dynamics simulations we find that each of these steps is affected differently by crowding proteins, which can either be bound to the D...
