Abstract

fetched live from OpenAlex

Two dark and raised foci were observed on the left hemisphere of the brain of a 3-year-old cynomolgus monkey during the routine necropsy procedures of a preclinical toxicity study. Microscopic examination revealed a lesion in the cerebral cortex at the junction of the parietal and occipital lobes, consisting of disorganized, but generally well-circumscribed collections of mixed glial and neuronal cells within a fibrillar stroma. Numerous eosinophilic granular bodies, brown pigment-laden macrophages, and lymphocytic infiltrates were also noted. Immunohistochemical staining for glial fibrillary acidic protein, neurofilament, and Ki-67, as well as histochemical stains Masson's Trichrome and Klüver-Barrera confirmed the presence of both glial and neuronal cells within a collagenous stroma, without significant proliferation. Both histopathological and immuno/histochemical stains were consistent with a glioneuronal hamartoma. This report describes the first case of such a lesion in a nonhuman primate.

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.
