Abstract
OBJECTIVE: To evaluate the efficacy of a chemically modified and cross-linked derivative of hyaluronan (CMHA-SX) for treatment of corneal epithelial abrasion and standardized alkali burn injuries. ANIMALS: Twelve female New Zealand white rabbits in two groups were used. PROCEDURES: Bilateral 6-mm diameter corneal epithelial abrasions were made in each of six rabbits in one group and 6-mm standardized alkali burn injuries were made in the second group. A 1% CMHA-SX formulation was applied topically four times per day in right eye of each rabbit for 1 week, and phosphate buffered saline (PBS) was placed in left (control) eye of each rabbit. The wound size was determined by staining with 1% fluorescein and photographed at the slit lamp with a digital camera at 0, 1, 2, 3 days postoperatively in the first group and 0, 1, 2, 3, 7, 12 days in the second group. Rabbit corneas were collected for histological examination on day 7 in the first group and day 12 in the second group. RESULTS: Closure of corneal wound in the abrasion model was complete in the CMHA-SX treated eye by 48 h. The wound closure rate and thickness of the central corneal epithelium in the CMHA-SX treated group was greater than in control eyes for both the abrasion and alkali burn injuries. Moreover, the CMHA-SX treated cornea exhibited better epithelial and stromal organization than the untreated control cornea. CONCLUSIONS: Chemically modified and cross-linked derivative of hyaluronan improved corneal wound healing and could be useful for treating noninfectious corneal injuries.

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
