An unexpected complication: Air embolism during contrast-enhanced computed tomography

Radiology Case Reports
Air embolism is often an iatrogenic complication that may occur in venous or arterial circulation depending on the port of entry. We present a case of a 40-year-old female who had a venous air embolism in the pulmonary artery as a consequence of the ...

Diversity and Plasticity of Hydraulic Traits Across a Relative Moisture Supply Gradient: Results From Multiple Common Gardens

Plant, Cell &Environment, EarlyView.
ABSTRACT Maintaining cellular hydration is essential for plant metabolic activity and carbon gain. Plants typically maintain hydration through efficiency of water transport networks, the ability to avoid network disruption, and retention of water via accumulation of osmotica. Given their global domain and their enduring presence across geological eras,

Early plasma administration in traumatic brain injuries: A systematic review

Transfusion, EarlyView.
Abstract Background Early plasma may improve trauma resuscitation by addressing shock and coagulopathy, but its role in traumatic brain injury (TBI) remains uncertain. This systematic review evaluated early plasma in TBI. Methods This review followed Cochrane methodology and was registered in PROSPERO (CRD420261357882).

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.
