Increased Oxidative Modifications of Amniotic Fluid Albumin in Pregnancies Associated with Gestational Diabetes Mellitus
Bibliographic record
Abstract
Gestational diabetes mellitus (GDM) is a state of hyperglycaemia and increased oxidative stress with onset during pregnancy. Human serum albumin (HSA) was extracted from 26 GDM and 26 nonGDM amniotic fluid samples collected at 15 weeks gestation and analyzed by mass spectrometry. The majority of all albumin isoforms were oxidized with the cysteinylated HSA as the base peak in the deconvoluted spectrum. The HSA peak areas, from a control sample, had 36% relative standard deviation (RSD) across the six experimental days but using the relative isoform distribution improved the precision to 3-6%. The results show that the relative contribution of permanently oxidized HSA was greater (P = 0.002) and reversibly oxidized HSA was lower (P = 0.006) for GDM compared to nonGDM in the samples measured. This implies that the path toward GDM has been set prior to 15 weeks gestation and results in increased protein 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.
