Relationship between vanadate induced relaxation and vanadium content in guinea pig taenia coli
Bibliographic record
Abstract
Vanadate has been known to induce a transient increase in high K+induced contraction, and also gradually relax the high K+contraction itself in guinea pig taenia coli. The relationship between the rate of relaxation and ion content of Na+, K+, and V ion at the cellular level was investigated when vanadate was applied to contracted muscle. Tissue Na+and V ion content increased linearly, depending on the time after vanadate treatment, reaching maximum levels of approximately 50 mM·kg-1and 0.25 mM·kg-1wet weight, respectively. There was a positive correlation between the V ion and Na+contents, while there was a negative correlattion between both ions and the relaxed rate of the high K+induced contraction. The uptake of V ion was affected by the external K+concentration, and the maximum rate of V ion uptake decreased to 40% in the presence of 90 mM external K+. These results suggest that a small amount of V ion was enough to inhibit the Na+pump activity and muscle contraction in the high K+solution.Key words: vanadate, high K+, relaxation, taenia coli, vanadium.

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.
