Abstract

fetched live from OpenAlex

It has been established that the impairment of mitochondrial function is associated with various disorders, such as type 2 diabetes and Alzheimer's disease. In addition, mitochondria have been implicated in the progression of cellular aging through a multitude of studies that connect increased mitochondrial dysfunction, such as increased reactive oxygen species production and decreased ATP synthesis, with skeletal muscle undergoing sarcopenia. Studies reveal an inverse relationship between mitochondrial biogenesis and aging such that as an individual increases in age, mitochondrial function, and content decreases. This review aims to summarize the relationship of mitochondria with skeletal muscle function, the regulation of mitochondrial biogenesis, and the alterations in skeletal muscle and mitochondrial function that result due to the aging process.

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.
