Abstract
1. In the present study, we investigated the effects of exercise training on cardiac hypertrophy and oxidative stress in a monocrotaline (MCT)-induced cor pulmonale model. Male Wistar rats were assigned to one of three groups: sedentary control (SC); sedentary MCT (SM); or trained MCT (TM). 2. Right ventricular hypertrophy (RVH) was induced by a single injection of MCT (60 mg/kg, i.p.). Exercise training consisted of running on a treadmill (five times a week, during Weeks 3, 4 and 5). Systemic oxidative stress was evaluated in erythrocytes by chemiluminescence (CL) and the activity of the anti-oxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione S-transferase (GST) was determined. 3. At Week 3, MCT-treated animals exhibited RVH, lung congestion, decreased SOD activity and increased CAT activity. Exercise training reduced MCT-induced RVH and increased GST activity. At Week 4, MCT-induced RVH was accompanied by an increase in CL and GST activity. However, in TM animals there was a decrease in CL and augmented SOD activity. At Week 5, there were no survivors in the SM group, whereas GST activity was elevated in TM rats compared with SC rats. There was no difference in GPx activity throughout the experimental protocol between the groups. 4. Taken together, our results indicate that exercise training is able to ameliorate RVH and improve survival, which is associated with a reduction in oxidative stress in MCT-treated rats.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
