Extracorporeal membrane oxygenation in trauma patient in France: A retrospective nationwide registry.

Background: Indications for Veno-venous (VV) or veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) after trauma rely on poor evidence. The main aims were to describe the population of trauma patients requiring either VV or VA ECMO and report their clinical management and outcomes.

Methods: An observational multicentre retrospective study was conducted in 17 Level 1 trauma centres in France between January 2010 and December 2021.

Entanglement and iSWAP gate between molecular qubits.

Quantum computation and simulation rely on long-lived qubits with controllable interactions. Trapped polar molecules have been proposed as a promising quantum computing platform, offering scalability and single-particle addressability while still leveraging inherent complexity and strong couplings of molecules. Recent progress in the single quantum state preparation and coherence of the hyperfine-rotational states of individually trapped molecules allows them to serve as promising qubits, with intermolecular dipolar interactions creating entanglement.

Acidification-based mineral weathering mechanism involves a glucose/methanol/choline oxidoreductase in PML1(12).

Unlabelled: While mineral weathering (MWe) plays a key role in plant growth promotion and soil fertility, the molecular mechanisms and the genes used by bacteria to weather minerals remain poorly characterized. Acidification-based dissolution is considered the primary mechanism used by bacteria. This mechanism is historically associated with the conversion of glucose to protons and gluconic acid through the action of particular glucose dehydrogenases (GDH) dependent on the pyrroquinoline quinone (PQQ) cofactor.

Chronic stimulation desensitizes β2-adrenergic receptor responses in natural killer cells.

Adrenergic receptors (ARs) are preferentially expressed by innate lymphocytes such as natural killer (NK) cells. Here, we study the effect of epinephrine-mediated stimulation of the β2-adrenergic receptor (β2AR) on the function of human NK cells. Epinephrine stimulation inhibited early NK cell signaling events and blocked the function of the integrin LFA-1.
