Abstract

fetched live from OpenAlex

Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited neurodegenerative disorder causing progressive spasticity, ataxia and peripheral neuropathy, leading to significant motor and sensory impairments. To advance the study of ARSACS pathogenesis and therapeutic development, we generated eight induced pluripotent stem cell (iPSC) lines from patient-derived fibroblasts or peripheral blood mononuclear cells (PBMCs) using non-integrating Sendai virus-based reprogramming method and covering four different SACS gene mutations. These iPSC lines provide a powerful platform to investigate disease mechanisms, evaluate therapeutic candidates, and support the development of personalized medicine approaches for ARSACS.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
