Failure of Two Distinct Anti-apoptotic Approaches to Reduce Mortality in Experimental Cerebral Malaria
Bibliographic record
Abstract
Cerebral malaria is responsible for a high proportion of mortality in human Plasmodium falciparum infection. Previous studies have reported the presence of apoptosis in endothelial cells, astrocytes, neurons, and glial cells in experimental murine cerebral malaria caused by infection with Plasmodium berghei ANKA. Using this model, we tested two strategies, which have been shown to improve survival in murine models of sepsis: 1) treatment with z-VAD, a pancaspase inhibitor; and 2) overexpression of Bcl-2 using transgenic mice expressing human Bcl-2 (which prevents the release of apoptotic mediators from the mitochondria) from a myeloid cell promoter. Neither of these anti-apoptotic strategies, previously shown to provide therapeutic benefit in sepsis, improved survival in experimental cerebral malaria.

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.
