Therapeutic potential of Na-H exchange inhibitors for the treatment of heart failure
Bibliographic record
Abstract
The Na-H exchanger (NHE) represents a family of transporters which regulate intracellular pH by removing protons in exchange for sodium influx in an electroneutral 1:1 stoichiometric relationship. Six isoforms have thus far been identified with the NHE-1 subtype representing the primary isoform in the cardiac cell. It is well-established that NHE-1 contributes to cardiac injury produced by ischaemia and reperfusion and inhibitors of the antiporter exert excellent cardioprotection. More recent evidence suggests that NHE-1 may also be important for cell growth and may contribute to the maladaptive remodelling which contributes to heart failure particularly the early hypertrophic responses. Evidence from in vitro studies suggest that NHE-1 inhibitors attenuate cardiomyocyte hypertrophy in response to various stimuli whereas in vivo studies report substantial attenuation of both hypertrophy and heart failure by these agents, especially after myocardial infarction. Accordingly, NHE-1 inhibitors could emerge as important therapeutic tools for the attenuation and treatment of heart failure.

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.
