Evaluation of bile acids (BA) is useful for assessing the changes of intestinal flora in patients with ulcerative colitis (UC). During enterohepatic circulation, the intestinal micro flora cause 7 alpha-dehydroxylation of cholic acid (CA) and chenodeoxycholic acid (CDCA), yielding deoxycholic

Macromitophagy controls mitochondrial quality and quantity. It involves the sequestration of dysfunctional or excessive mitochondria within double-membrane autophagosomes, which then fuse with the vacuole/lysosome to deliver these mitochondria for degradation. To investigate a physiological role of macromitophagy in yeast, we
