Preliminary attempts to establish a rat model of striatal injury in glutaric acidaemia type I
Bibliographic record
Abstract
Glutaric acidaemia type I (GA I) is caused by the deficiency of glutaryl-CoA dehydrogenase, resulting in accumulation of glutaric acid (GA) and 3- hydroxyglutaric acid (3-OH-GA) in blood and cerebrospinal fluid (CSF). Neuropathological changes with onset in childhood consist of severe neuronal loss in the caudate and putamen. An animal model is necessary to test possible intervention strategies, and prior reports suggested that GA or 3-OH-GA could be used to create specific neuron loss in adult rats. Adult, 3-week-old and 2-week-old rats received intrastriatal injections of GA and 3-OH-GA at a range of doses. High concentrations caused necrotic lesions in striatum. Low concentrations caused white-matter axonal damage and small areas of neuron loss. Injection of lipopolysaccharide prior to administration of 3-OH-GA was not associated with enhanced neuronal loss. Our findings contradict prior claims and we conclude that the simple model of a single GA or 3-OH-GA injection into rat brain does not replicate the neuropathological findings in humans.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
