Abstract

fetched live from OpenAlex

We are interested in identifying human fungal allergens and antigens from species common on water-damaged or damp building materials for use as marker proteins and diagnostic tests. The cellulolytic fungus Chaetomium globosum is common on damp materials in the building environment worldwide. ELISA and immunoblotting tests identified two related proteins of molecular weights 45 and 47 kDa which were identified as fungal antigens found on spore surfaces and in culture filtrate. The sequences were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS), which indicated that the two proteins were chitosanases, confirmed by enzyme assay. The 47 kDa protein was not glycosylated and had an acidic pI of 4.5. These proteins have not been reported from other fungi and similar antigens were not seen in other fungi common in buildings. The production of polyclonal antibodies in rabbits showed the antigenicity of the target proteins and confirmed they were not artifacts of the isolation process. The proteins isolated are useful biomarkers for the detection of C. globosum in the building environment.

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.
