FlgV forms a flagellar motor ring that is required for optimal motility of Helicobacter pylori.

Flagella-driven motility is essential for Helicobacter pylori to colonize the human stomach, where it causes a variety of diseases, including chronic gastritis, peptic ulcer disease, and gastric cancer. H. pylori has evolved a high-torque-generating flagellar motor that possesses several accessories not found in the archetypical Escherichia coli motor.

Control of the flagellation pattern in by FlhF and FlhG.

FlhF and FlhG control the location and number of flagella, respectively, in many polar-flagellated bacteria. The roles of FlhF and FlhG are not well characterized in bacteria that have multiple polar flagella, such as . Deleting in shifted the flagellation pattern where most cells had approximately four flagella to a wider and more even distribution in flagellar number.

Prevalence of ICU Delirium in Postoperative Pediatric Cardiac Surgery Patients.

Objectives: The objective of this study was to determine the prevalence of ICU delirium in children less than 18 years old that underwent cardiac surgery within the last 30 days. The secondary aim of the study was to identify risk factors associated with ICU delirium in postoperative pediatric cardiac surgical patients.

Design: A 1-day, multicenter point-prevalence study of delirium in pediatric postoperative cardiac surgery patients.
