The role of reactive oxygen, nitrogen, and sulfur species in the integration of (a)biotic stress signals in legumes.

Legumes are crops of considerable economic and ecological significance. They are suitable for cultivation in a variety of environments and temperatures. They are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia, contributing to the enrichment of marginal soils with this essential nutrient, and reduce artificial fertilizer use.

Does Leak Matter? A Novel Dynamic Leak Model to Simulate Leak for Performance Testing of Manual Neonatal Resuscitation Devices. A Bench Study.

Introduction: Newborn resuscitation is commonly performed in the presence of face mask leak. Leak is highly variable, pressure-dependent and often unrecognized. The effectiveness of resuscitation devices to deliver adequate inflations in the presence of leak is unknown.

What CPAP to use in the delivery room? Bench comparison of two methods to provide continuous positive airways pressure in neonates.

Background: Continuous positive airway pressure (CPAP) is a recommended first-line therapy for infants with respiratory distress at birth. Resuscitation devices incorporating CPAP delivery can have significantly different imposed resistances affecting airway pressure stability and work of breathing.

Aim: To compare CPAP performance of two resuscitation devices (Neopuff T-piece resuscitator and rPAP) in a neonatal lung model simulating spontaneous breathing effort at birth.

Atypical rhizobia trigger nodulation and pathogenesis on the same legume hosts.

The emergence of commensalism and mutualism often derives from ancestral parasitism. However, in the case of rhizobium-legume interactions, bacterial strains displaying both pathogenic and nodulation features on a single host have not been described yet. Here, we isolated such a bacterium from Medicago nodules.
