Using electron probe X-ray microanalysis to study calcium release from atrial specific granules induced by injection of adrenaline in rats
Bibliographic record
Abstract
Whether the release of Ca from atrial specific granules (ASG) can promote ASG secretion was studied. The ultrathin cryosections and ethanolic phosphotungstic acid staining sections of rat atrial cardiocytes were prepared. Quantitative electron probe X ray microanalysis of Hall continuum method was adopted to measure the alteration of Ca content in ASG at the exact time intervals of 15, 30, 60, 120 min after the adrenaline (Ad) administration. The numerical density (N v ) was measured to estimate the ASG secretion. It was observed that the N v of ASG gradually decreased and reached the lowest value at the time of 60 min after the Ad administration. Meanwhile, the Ca content of ASG gradually decreased and reached the lowest value at the time of 30 min after the Ad administration. It showed that the decrease in Ca content took place earlier than that of ASG number. Accordingly, it suggested that the Ca released from ASG due to Ad stimulation might become a messenger triggering atrial natriuretic peptide secretion. The quantitative electron probe X ray microananlysis of Hall continuum method was discussed in this paper.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
