Cover Feature: In Vitro Selection and Characterization of a DNAzyme Probe for Diverse Pathogenic Strains of <i>Clostridium difficile</i> (Chem. Eur. J. 36/2023)
Bibliographic record
Abstract
An RNA-cleavage fluorogenic DNAzyme has been made for recognizing diverse strains of Clostridium difficile that frequently cause an infectious disease known as C. difficile infection (CDI). Upon encountering C. difficile cells, this DNAzyme cuts itself to produce a fluorescent signal, thus making it useful as a molecular probe for CDI diagnosis. This DNAzyme is highly specific as it stays silent in the presence of several control bacterial cells. The DNAzyme has an intriguing secondary structure with a pseudoknot arrangement that is essential for its functionality. More information can be found in the Research Article by Y. Li and co-workers (DOI: 10.1002/chem.202300240).

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.
