Abstract

fetched live from OpenAlex

OBJECTIVE: To determine if there is a dose-response curve for TGF-beta1 in a rabbit calvarial defect model. STUDY DESIGN: Controlled animal study using arms of increasing concentrations of TGF-beta1 to evaluate the osteoinductive potential of each arm. METHODS: Sixteen skeletally mature New Zealand white rabbits were randomized into control and experimental arms. Incremental doses of TGF-beta1 delivered in an inactivated guanidine-extracted demineralized bone matrix (Gu-DBM) carrier were implanted into a critically sized calvarial defect. The animals were sacrificed at 4 weeks and histomorphometric analysis was then accomplished. RESULTS: TGF-beta1 showed a dose-response relationship, with the higher doses chosen for this study causing more robust osteoinduction. CONCLUSIONS: In this pilot dosing study, TGF-beta1 demonstrates increasing osteoinduction with increasing dose levels in this animal model.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
