Salidroside induced repair of myocardial infarction through Nrf2/HO-1
Bibliographic record
Abstract
Abstract Salidroside (SAL) has been confirmed to have some protective effects against inflammatory injury. However, little information was established as to the mechanism of these protective effects. To this effect, we designed this study to explore the protective effects and mechanisms of SAL against myocardial infarction (MI). A rat MI model was established and divided into five groups (n = 6): sham, MI, MI+SAL, MI+ LY294002 (PI3K inhibitor), and MI+SAL+ LY294002. The cardiac function and histological pathology were analyzed with a color Doppler ultrasonic diagnostic instrument. Anti-oxidative enzyme activities and the production of inflammatory media were assayed by biochemical kits and ELISA. MI size and fibrosis were assayed by Masson’s trichrome staining while Bax/Bcl-2 and PI3K/Akt/Nrf2/HO-1 were assayed by Western blotting and immunofluorescence. The results showed that SAL significantly improved the left ventricle ejection fraction and fractional shortening, decreased the MI size and fibrosis, inhibited apoptosis and promoted blood vessel formation. SAL promoted anti-oxidative and anti-inflammatory abilities. Moreover, SAL enhanced PI3K/ Akt/Nrf2/HO-1 expression. To this effect, we designed this study suggested that SAL induced repair of MI via PI3K/A kt/ Nrf2/HO-1.

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.
