Mitochondrial functions and content of microsomal and mitochondrial cytochromes in human cirrhosis.
نویسندگان
چکیده
1. Mitochondria and microsomal fractions have been isolated from liver biopsies from patients with alcoholic cirrhosis, cryptogenic cirrhosis or chronic aggressive hepatitis. 2. Cirrhotic livers yieled fewer mitochondria than normal liver. 3. The most significant change was a decrease in mitochondrial respiratory control. Cirrhotic microsomal fractions had a 50% diminution in cytochrome b5 and cytochrome P-450 content. 4. The two patients with chronic aggressive hepatitis showed similar mitochondrial and microsomal changes.

Interspecies variation in the hepatic biotransformation of zearalenone: Evidence for bio-inactivation of mycoestrogen zearalenone in sturgeon fish
Zearalenone (ZEA) as mycoestrogen is found in human foods and animal feeds. Its estrogenic potency depends on its biotransformation fate. The hepatic biotransformation of ZEA in two species of sturgeon fish (Acipenser persicus and Huso huso) was investigated. ZEA was incubated with the hepatic microsomal and post-mitochondrial sub-fractions in the presence of NADPH and the metabolites were dete...

Background: Calcium overload and free radical mediated damage in the mitochondria is the most important pathological changes associated with myocardial ischemic-reperfusion injury. The verapamil post-treatment has been previously reported to prevent reperfusion-induced myocardial injury but functional recovery may be delayed due to the drug's inherent direct myocardial depression effect. In the...

Mycoestrogen zearalenone (ZEA) is found in human foods and animal feeds. Its estrogenic potencymainly depends on its biotransformation fate. The hepatic biotransformation of ZEA in rainbow trout wasinvestigated in this study. Various concentrations of ZEA were separately incubated with the hepaticmicrosomal and post-mitochondrial sub-fractions in the presence of NADPH, and the metabolites wered...

Background: Mitochondria are the most aboudent and small essential organelles found in eukaryotic cells. These are semiautonomous organelles for the production of cellular ATP that through its various biochemical pathways. The primary pathway for ATP production is OXPHOS via the electron transfer chain (ETC) which is encoded by nuclear DNA and mtdna genomes. Mitochondria consist of double stran...
