PULMONARY ELASTIN SYNTHESIS AND DEPOSITION IN DEVELOPING AND MATURE SHEEP: EFFECTS OF INTRAUTERINE GROWTH RESTRICTION
Bibliographic record
Abstract
Hypoxia and nutrient restriction during gestation restrict fetal growth and alter lung development. As elastin is intimately involved in lung development, our aim was to assess pulmonary elastin synthesis and deposition following intrauterine growth restriction (IUGR) induced by umbilicoplacental embolization (UPE). Pulmonary tropoelastin expression and elastin content were examined at 128 days (5 days UPE) and 140 days (20 days UPE) of the 147- days gestation and at 8 weeks and 2.3 years after birth (both approximately 27 days UPE) in sheep. UPE induced hypoxemia, hypoglycemia, and fetal growth restriction but did not affect pulmonary tropoelastin mRNA levels or elastin deposition at any age; furthermore, elastin content was unaltered apart from being lower at 140 days. The authors conclude that hypoxemia and undernutrition associated with IUGR do not affect elastin synthesis and deposition in fetal lungs; alterations in lung structure following IUGR must have other causes.

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.
