Abstract
Helicobacter pylori is a gram negative pathogen that infects at least half of the world's population and is associated not only with gastric cancer but also with other diseases such as gastritis and peptic ulcers. Indeed, H. pylori is considered the single most important risk factor for the development of gastric cancer. The vacuolating cytotoxin VacA, secreted by H. pylori, promotes intracellular survival of the bacterium and modulates host immune responses. In a recent study, we reported that VacA induces autophagy. Multilamellar autophagosomes are detected in gastric epithelial cells that are distinct from the large vacuoles formed by VacA. Furthermore, inhibition of autophagy stabilizes VacA and reduces vacuolation in the cells indicating that the toxin is being degraded by autophagy, thus limiting toxin-induced host cell damage. Many of the methods that were used for this study are commonly employed techniques that were adapted for H. pylori infection and VacA intoxication. In this paper, we describe the various methods and specific protocols used for the assessment and monitoring of autophagy during H. pylori infection.

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 it
