Transport du Na<sup>+</sup>dans les poumons
Bibliographic record
Abstract
Na+ transport by airway epithelial cells, in conjunction with Cl- secretion is crucial for maintaining an adequate level of airway surface liquid (ASL) for an effective mucociliary clearance by the ciliated airway epithelial cells. It is also an important mechanism for lung liquid absorption at birth and oedema absorption during an acute respiratory distress syndrome (ARDS). The epithelial Na+ channel (ENaC) is the channel mostly involved in this process. The consequences of an imbalance in ENaC activity in the airways and in the distal lung are different. Experimental over expression of ENaC in the airways leads to a decrease in mucociliary clearance and inflammation similar to cystic fibrosis and chronic bronchitis. However, bacterial and viral pathogens, as well as pro-inflammatory cytokines present during lung infection downregulate ENaC expression and activity in airway and alveolar epithelial cells. ENaC downregulation by pathogens or inflammatory products could participate in the modulation of the severity of ARDS. Pharmacological strategies that modulate ENaC expression or activity could be important in the treatment of different lung diseases since it is actively involved in the lung innate defence mechanisms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
