A Polymeric Nanobeacon for Monitoring the Fluctuation of Hydrogen Polysulfides during Fertilization and Embryonic Development
Bibliographic record
Abstract
Abstract Fertilization and early embryonic development as the beginning of a new life are key biological events. Hydrogen polysulfide (H 2 S n ) plays important roles during physiological regulation, such as antioxidation‐protection. However, no report has studied in situ H 2 S n fluctuation during early embryonic development because of the low abundance of H 2 S n and inadequate sensitivity of probes. We herein construct a polymeric nanobeacon from a H 2 S n ‐responsive polymer and fluorophores, which is capable of detecting H 2 S n selectively and of signal amplification. Taking the zebrafish as a model, the polymeric nanobeacon revealed that the H 2 S n level was significantly elevated after fertilization due to the activation of cell multiplication, suppressed partially during embryonic development, and finally kept steady up to zebrafish emergence. This strategy is generally accessible for biomarkers by altering the responsive unit and significant for facilitating biological analysis during life development.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
