Glucose‐free medium exacerbatesmicrovesicular steatosis in cultured skin fibroblasts of genetic defects of fatty acid oxidation. A novel screening test
Bibliographic record
Abstract
Skin fibroblasts from patients with various fatty acid oxidation defects (FAOD) and four normal controls were subcultured in standard glucose-containing medium or in glucose-free medium simulating fasting. The FAOD fibroblasts developed microvesicular steatosis, which was greatly exacerbated in glucose-free medium. 'Rescue treatment' with glucose-containing medium was performed in the short-chain L-3-hydroxyacyl-CoA dehydrogenase-deficient (SCHADD) fibroblasts and resulted in a partial resolution of the steatosis and improved cellular viability. Transmission electron microscopy of autopsy specimens from the SCHADD patient demonstrated that most renal interstitial fibroblasts and approximately 50% of fibroblasts in the heart had microvesicular steatosis. The demonstration of microvesicular steatosis in parenchymal and/or cultured skin fibroblasts may provide important and cost-effective screening tools for the detection of genetic defects of fatty acid oxidation.

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.
