Impaired chemoreflex sensitivity during septic shock induced by cecal ligation and perforation
Bibliographic record
Abstract
In this study, we sought to determine the effects produced by cecal ligation and perforation (CLP) on the autonomic responses to the activation of peripheral chemoreflexes in conscious rats. The peripheral chemoreflex was activated with potassium cyanide (KCN; 40 μg·(0.1 mL)(-1); intravenous injection (i.v.)) in male Wistar rats 3, 6, 12, and 24 h after CLP or sham surgery. The mean arterial pressure (MAP), heart rate (HR), and respiratory frequency (fR) were recorded simultaneously. CLP surgery reduced the baseline MAP when compared with the sham animals. In the animals of the sham group, the autonomic responses to KCN produced increases in MAP and fR as well as a decrease in HR. However, 12 and 24 h after CLP surgery, the autonomic responses to KCN were attenuated. The restoration of MAP by i.v. injected l-NAME or phenylephrine did not restore the autonomic response to KCN in rats subjected to CLP. These data show that septic shock induced by CLP compromised the autonomic responses to peripheral chemoreflex activation in conscious rats, suggesting that an important regulatory mechanism is impaired during the course of this condition.

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.
