Abstract
BACKGROUND: Endothelial glycocalyx (EG) is a carbohydrate-rich gel-like mesh covering the apical surface of endothelial cells. It has been linked to the microvascular pathophysiology and tissue metabolism. However, little is known about its condition in young healthy adults. OBJECTIVE: We aimed to describe the condition of EG in young healthy adults by in vivo EG imaging and measurement of syndecan-1, a plasma marker of EG integrity in order to obtain reference values. METHODS: For in vivo EG studies we used Side-stream Dark Field imaging of the sublingual microcirculation. Recordings were analysed automatically by GlycoCheck software providing the Perfused Boundary Region (PBR) as a marker of EG thickness. Levels of syndecan-1 were analysed in plasma samples by ELISA. RESULTS: 21 volunteers were included in the study. Median of the PBR value was 1.82 μm (interquartile range 1.69-2.01, 95% CI 1.79-1.97). Median concentration of syndecan-1 was 0.3 ng/ml (interquartile range 0.23-0.39, 95% CI 0.27-0.49). CONCLUSION: This study provides a comparison for cohorts of patients with a particular disease where the EG is presumably damaged. Our findings do not entirely comply with already published data in healthy individuals.

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
