The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Impact of Priming Volume Reduction on Hematocrit Retention in Pediatric Cardiopulmonary Bypass: A Retrospective Analysis

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Retrograde autologous priming and venous antegrade priming replace the cardiopulmonary bypass circuit crystalloid with patient blood to mitigate hemodilution. However, their effectiveness in pediatric patients, particularly when analyzed as continuous variables, remains unclear.
