Abstract

fetched live from OpenAlex

Earlier, it was reported that most of the allergenic activity of Alternariatenuis seemed to reside in the last Sεphadex G-100 fraction (G3, molecular weight ∼ 20,000). These conclusions were based on results obtained by the in vitro techniques of radioallergosorbent tests (RAST) and RAST inhibition. In the present studies, the allergenic activity of A. tenuis fractions was measured in vivo. It was found that fraction G3 was neither capable of inducing reaginic (IgE) antibodies in rats nor eliciting a skin reaction in rats sensitized with reagins against A. tenuis non-dialyzable fraction (MW > 12,000). On the other hand, subtractions G2D3 and G2D4 obtained from the middle fraction of G-100 (G2, MW ∼ 30,000–40,000) followed by ion-exchange chromatography on DEAE-cellulose, showed the greatest allergenic activity in vivo, giving high titered reaginic antibodies in rats. When compared by RAST inhibition, the activities of fractions G2D3 and G2D4 were slightly lower than that of G3. Fraction G3 was immunogenic in rabbits. In immunodiffusion tests, G2D3, G2D4 and G3 appeared to be identical and they were cross-inhibiting in RAST inhibition tests. It was concluded that the sizes and multivalent properties of G2 and G3 antigens exerted a strong influence on their allergenic activities in rats (IgE antibody production) but this factor was of little importance for their antigenic activity in rabbits (precipitin antibody production) and their behaviour in the in vitro tests.

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.
