Abstract

fetched live from OpenAlex

Primary cutaneous amyloidosis is characterized by polymerization of extracellular amyloid precursors in β-pleated sheet conformation into larger fibrillar aggregates. Observation in models of Alzheimer's disease have noted that amyloid polymerization in the brain is blocked by reactive oxygen species. Singlet oxygen is formed in the skin during methyl aminolevulinate photodynamic therapy. Therefore, we speculate that type II photochemical reaction is responsible for the observed therapeutic activity of methyl aminolevulinate photodynamic therapy in our patient with primary cutaneous amyloidosis. Our case is the first report demonstrating the efficacy of daylight photodynamic therapy in primary cutaneous amyloidosis. Daylight photodynamic therapy may provide a convenient and cost-effective therapeutic option in primary cutaneous amyloidosis, and its efficacy should be further confirmed in prospective trials.

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.
