GFA Content, Glutamate Uptake and Activity of Glutamate Metabolizing Enzymes in Differentiating Mouse Astrocytes in Primary Cultures
Bibliographic record
Abstract
The effects on GFA content, glutamate uptake and activity of glutamate metabolizing enzymes (glutamine synthetase, glutamate dehydrogenase, glutamate-oxaloacetate transferase) by three variables, i.e., length of culturing period, presence or absence of serum, and presence or absence of dibutyryl cyclic AMP (dBcAMP) were studied in primary cultures of astrocytes from newborn mice. During 3 weeks of culturing the content of GFA, the rate of glutamate uptake and the activity of all three enzymes increased but the period of maximum increase differed between the different parameters. The GFA content and the Vmax and Km for glutamate uptake were increased by dBcAMP and decreased by serum withdrawal but the enzyme activities were relatively little affected.

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.
