Abstract
Replication protein A (RPA) has been identified as a component of early recombination nodules. It is thought to stimulate homologous pairing and strand exchange reactions. The expression pattern of RPA in human spermatocytes has been analysed using immunocytogenetic techniques on testicular biopsies from adult male patients. What appears to be connecting RPA-filaments was observed between as yet unsynapsed homologous regions at early stages of zygotene. RPA foci were also observed in synaptic segments at zygotene and early pachytene, in numbers that peak at the end of zygotene. The presence of a localization pattern for RPA was also detected, but statistical analysis of distances between adjacent RPA foci shows that this pattern does not always follow a gamma distribution. Finally, it was determined that RPA is absent from non-centromeric heterochromatin in chromosome 9. The observed bridge-like structure could be the visualization of a proposed pre-synaptic RPA role in the strand invasion that precedes the formation of a Holliday Junction. These observations strengthen the original pre-synaptic model, although the visualization of post-synaptic RPA foci may indicate the presence of a different role for this protein during homologous recombination.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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
