Abstract

fetched live from OpenAlex

Atypical BSE is an invariably fatal neurologic disease of cattle caused by misfolded prion proteins with different conformations than those associated with classical BSE. Evidence suggests that these atypical BSE types are sporadic or genetic prion diseases of cattle and the relevance of these diseases, as far as natural transmissibility, is still unknown. Different misfolded prion protein conformations also result in unique biochemical characteristics. This raised concerns about detection of atypical BSE on rapid test platforms designed and validated for classical BSE prions. Despite the differences in the misfolded prion protein characteristics, studies have shown that the tests also work well for detecting the known types of atypical BSE. A new question that has recently emerged is related to the possibility of additional forms of atypical BSE. Initially reactive bovine brain samples on certain rapid surveillance tests have sparked debate about the true BSE status of these samples. Work is currently underway to determine if these samples are infectious and if they eventually result in neurologic disease in cattle. Results of these studies could impact future BSE diagnostic testing programs as well as human and animal health policies.

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.
