Metallothionein-like proteins in <i>Macoma balthica</i>: effects of metal exposure and natural factors
Bibliographic record
Abstract
Biological processes involved in the tolerance acquired by populations chronically exposed to metal pollution in the environment were examined in baltic clams (Macoma balthica) originating from both industrialized and clean areas and in clams exposed experimentally to metals. It has been shown previously that clams surviving Ag and Hg exposure at LT50 did not protect themselves by accumulating smaller amounts of metals than clams that failed to survive, so attention was focussed on the physicochemical forms of storage of the accumulated metals. Silver was found to be predominantly bound to insoluble forms and Cd and Hg to soluble forms. In both controls and contaminated clams, a metallothionein-like protein (MTLP) has been shown to be present, the concentrations of which did not depend on the geographical origin of the clams. The significant relationship between metal and MTLP concentrations shown in the baltic clams suggests that the induction of this protein could provide a useful tool for the biomonitoring of metal pollution. The influence of natural factors (season, weight), however, must be taken into account when interpreting such data.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
