High-cervical spinal cord injury (SCI) often disrupts respiratory motor pathways and disables breathing in the affected population. Moreover, cervically injured individuals are at risk for developing acute lung injury (ALI), which predicts substantial mortality rates. While the correlation between ALI and SCI has been found in the clinical setting, the field lacks an animal model to interrogate the fundamental biology of this relationship. To begin to address this gap, we performed an experimental cervical SCI and assessed lung injury in adult rats. We demonstrate that animals display signs of ALI two weeks post-SCI. We also observed aberrant N-glycan metabolism determined by matrix-assisted laser desorption/ionization mass spectrometry imaging. Collectively, we establish for the first time a model of ALI after SCI at an acute time point that can be used to monitor the progression of lung damage, as well as identify potential targets to ameliorate ALI.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
