To quantify mitochondrial volume, cells were imaged with z-stacks consisting of 250 planes and an interval of 0.147m

These DMCs were then ranked, followed by the selection of N marker CpGs per cell type, comprising the N/2 DMCs with the largest positive t -statistics and the N/2 DMCs with the largest negative t -statistics
Small decreases are noted between ages 30 and 50 and decreases accelerate after the fifth decade of life, with some people experiencing as much as a 15 percent strength loss per decade, with more than 50 percent of fast-twitch muscle fibers being lost by 75 years of age
