The antioxidant α-lipoic acid attenuates intermittent hypoxia-related renal injury in a mouse model of sleep apnea
Bibliographic record
Abstract
STUDY OBJECTIVES: Oxidative stress and inflammation are proposed to mediate kidney diseases that occur in patients with obstructive sleep apnea (OSA). We examined the hypothesis that α-lipoic acid (LA) prevents renal injury in a mouse model of sleep apnea. METHODS: Twenty male mice received either intermittent hypoxia (IH) or intermittent air (IA) with or without a LA-enriched diet for 60 days. Plasma and urine samples were collected at the end of study, and kidneys were harvested for protein analysis. RESULTS: Animals in the IH + LA group had lower levels (p < 0.05) of plasma oxidative stress (8-isoprostane) and inflammation (TNF-α). Renal oxidative stress was also reduced in mice in the IH + LA (p < 0.05) compared with IH-exposed mice that were fed regular diet. Renal cellular apoptosis and tubular injury were reduced in the IH + LA group. Treatment with LA attenuated IH-induced glomerular hypertrophy and increased albuminuria. CONCLUSIONS: Treatment with LA prevents IH-induced renal injury in mice. LA may be a potential therapy for reducing renal dysfunction in patients with OSA. LA can also increase oxidative stress in healthy animals.

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.
