Bacteriophage carriers localize in the brain of a rat model of neonatal hypoxic‐ischemic encephalopathy
Bibliographic record
Abstract
BACKGROUND: Neonatal hypoxic-ischemic encephalopathy arises from a reduction of oxygen and blood supply to the infant brain and can lead to severe brain damage and life-long disability. The damage is greatest at the irreversibly injured necrotic core, whereas the penumbra is the surrounding, potentially salvageable tissue populated with a mix of alive and dying cells. To date, there exists no method for targeting drugs to the brain damage. METHODS AND MAJOR RESULTS: Bacteriophages are viruses that propagate in bacteria but are biocompatible in humans and also amenable to genetic and chemical modification in a manner distinctive from conventional therapeutic nanoparticles. Here, a library of M13 bacteriophage was administered into a rat model of hypoxic-ischemic encephalopathy, and unique bacteriophage clones were confirmed to localize in healthy brain tissue versus the core and penumbra zones of injury. CONCLUSIONS: For the first time, there is a potential to directly deliver therapeutics to different regions of the neonatal brain injury.

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.
