From Paralytic Poison to Medicinal Marvel: Curare Advances Anesthesia
Bibliographic record
Abstract
After extracting curare from vines like Chondrodendron tomentosum (left), South American natives stored the tarry toxin in pots (right) and slathered it on arrow tips to slay enemies and prey. Scientists would call the active compound d-tubocurarine for the bamboo tubes (right) that held the arrows. In the 1730s, French mathematician Charles Marie de La Condamine became the first to study curare during an Andean expedition to prove Newton's view of Earth as an oblate spheroid-rounder at the Equator than the poles. At the time, he attributed the death of a curare-injected hen to respiratory muscle paralysis. In a famed 1814 experiment, English naturalist Charles Waterton and colleagues used artificial ventilation to keep a curarized donkey alive. But it was not until 1938, when North American explorer Richard Gill imported 12 kg of Ecuadorian curare to treat his own muscle spasms, that the arrow poison would enter anesthetic practice. After E. R. Squibb & Sons acquired Gill's supply and purified it to make Intocostrin (right), former anesthesiologist and Squibb advisor Lewis H. Wright supplied the drug to Canadian anesthesiologist Harold Griffith. The latter soon published in Anesthesiology his success with Intocostrin for rapid muscle relaxation in 25 lightly anesthetized patients (1942; 3:418-20). And so began a revolution, in which the drawbacks of deep anesthesia-cardiac depression, explosion risk, severe nausea, and prolonged emergence-could finally be mitigated.

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; both teacher heads agree on what is shown here.
