Abstract

fetched live from OpenAlex

Conventional models of the pathogenesis of sepsis assume that microorganisms or their products are necessarily injurious to the host. In contrast, an evolutionary perspective suggests that host-microbial interactions are a symbiotic model and that disease results from the disruption of a mutually beneficial homeostatic state. Lipopolysaccharide (LPS) from gram-negative bacteria is a prototypical trigger of sepsis and a target for the development of novel therapeutics. The biological mechanisms underlying the recognition of, and response to, LPS are more characteristic of a hormone than of a toxin. All mammals carry endogenous stores of LPS and express dedicated carrier proteins, a cellular receptor complex, and mechanisms that specifically antagonize the response to LPS. Disruption of any component of this complex recognition system jeopardizes host defenses against infection with exogenous microorganisms. Thus, LPS is not less an endotoxin than an exohormone, and its neutralization may potentially result in either benefit or harm.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
