Early recovery pathway for hepatectomy: data-driven liver resection care and recovery.

In recent years, great progress has been made toward safer hepatobiliary surgical interventions. This has resulted in more widely available treatments for patients who in the past were ineligible for curative resection of primary liver tumors, liver metastases, and advanced biliary tumors. However, the rise in procedures has seen increasingly heterogeneous perioperative management, yielding strikingly disparate outcomes.

Role of Raf kinase inhibitor protein in Helicobacter pylori-mediated signaling in gastric cancer.

Helicobacter pylori is a helical bacterium that colonizes the stomach in over half of the world's population. Infection with this bacterium has been linked to peptic ulcer disease and gastric cancer. The bacterium has been shown to affect regulatory pathways in its host cells through specific virulence factors that control gene expression.

Accumulation of swimming bacteria near a solid surface.

We measured the distribution of a forward swimming strain of Caulobacter crescentus near a surface using a three-dimensional tracking technique based on dark field microscopy and found that the swimming bacteria accumulate heavily within a micrometer from the surface. We attribute this accumulation to frequent collisions of the swimming cells with the surface, causing them to align parallel to the surface as they continually move forward. The extent of accumulation at the steady state is accounted for by balancing alignment caused by these collisions with the rotational Brownian motion of the micrometer-sized bacteria.
