Electrical impedance tomography during the extubation phase in very preterm born infants.

Introduction Although many preterm born infants require invasive mechanical ventilation, it is also associated with detrimental effects. Early extubation should be pursued, but extubation failure is yet common. The critical transition to non-invasive ventilation is characterized by respiratory physiological changes, warranting non-invasive monitoring.

Behaviour of 7.62x39mm tracer and API bullets in soft tissue.

Some bullets, called tracer and API bullets, contain a pyrotechnical charge. The charge in the bottom of a tracer bullet burns in flight and enables the shooter or an observer to see the bullet's trajectory. An Armor Piercing Incendiary (API) bullet contains a hard core and a pyrotechnical charge that ignites on impact with a hard target.

Multiclass Steroid Profiling in Short-Finned Pilot Whale Blubber Using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).

Rationale: Wildlife scientists are quantifying steroid hormones in a growing number of tissues and employing novel methods that must undergo validation before application. This study tested the accuracy and precision of liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for use on blubber samples from short-finned pilot whales (Globicephala macrorhynchus). We expanded upon a method for corticosteroid quantification by adding analytes and optimizing internal standard (IS) application.
