Study on development and<i>in vitro</i>biodegradation behaviour of poly(D, L-lactide-co-glycolide) 75/25 bioscaffolds
Bibliographic record
Abstract
Three-dimensional porous scaffolds based on biodegradable polymers are widely researched for applications to replace and restore the functions of diseased or damaged organs. The requirements for the scaffolds include: highly interconnected pore structures to facilitate cell adhesion for tissue regeneration, maintenance of mechanical properties and structural integrity until cells adapt to its environment and biodegradability with a controlled degradation rate. This paper focuses on the development and in vitro biodegradation behaviour of poly (D,L-lactide-co-glycolide acid) (PLGA) 75/25 and changes on pore morphology affected by initial pore sizes and degradation media. The pore morphology, mechanical properties, and geometric transformation were examined over the course of 13 weeks. It is concluded that the PLGA 75/25 scaffolds degraded after seven weeks and completely degraded after 13 weeks. The degradation time of scaffolds with small pores and in distilled water was comparatively shorter due to poorer interconnectivity of the pores and a more aggressive environment.

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.
