Serum and Urine Concentrations of Protein, Urea, Sodium, and Potassium during the Immediate Postnatal Period of the Suckling Pig
Bibliographic record
Abstract
Serum and urine concentrations of protein, urea, Na and K were monitored between birth and 72 h in neonatal pigs. Serum protein increased (p less than 0.05) 37 mg/ml after suckling, while urinary protein temporarily increased (p less than 0.05) to 14.7 +/- 0.98 mg/ml by 12 h but declined (p less than 0.05) to birth values by 72 h. Urinary urea levels tripled (p less than 0.05) by 12 h and remained elevated. The ratio of urea of urea in the urine to that in the serum ranged from 17 to 29. Serum Na concentrations were stable (141--146 mEq/l) during the 72 h, and urinary Na levels were low (9--4 mEq/l) and decreased (p less than 0.05) by 72 h. Serum K fluctuated and was highest (p less than 0.05) at birth (6.4 +/- 0.26 mEq/l) and lowest by 72 h (4.4 +/- 0.26 mEq/l). Levels of K excreted in the urine were high (20.0--7.6 mEq/l) compared to blood levels. Colostral concentrations of Na were low (81--73 +/- 3.8 mEq/l) while K levels were high (24.3--28.8 +/- 1.39 mEq/l) compared to piglet serum levels.

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.
