the activity of aspartate aminotransferase (ast) in human serum has been widely determined as a diagnostic aid in liver disease. in this study, the effect of aluminium on ast isoenzymes in relation to aluminium intoxified patients has been investigated. using gel filtration chromatography technique with sephacryl s-300, mitochondrial aminotransferase (m-ast) and cytosolic aminotransferase (c-as...

aim : the aim of this study was to evaluate and compare three available methods for mitochondrial isolation from a human cell line to predict the best method for each probable application.   background : organelle isolation is gaining importance in experimental laboratory settings. mitochondrial dysfunction may affect tumorgenesis process. there are some evidences that transplantation of health...

in this study the uptake and metabolism of adenosine by mitochondria has been investigated. incubation of cem cells mitochondria preparation with [3h] -adenosine showed substantial uptake and metabolism of adenosine. adenosine was both anabolized to amp, adp and atp, and also catabolized to inosine. the highest concentration of metabolites in extracted mitochondria was due to amp. the mitochond...

Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on ...

doxorubicin (dox) is an anthracycline antibiotic that has been used for a long time in therapy of an array of human malignancies either alone or in combination with other cytotoxic agents. the dose-dependent cardiotoxicity of dox significantly limits its anticancer efficacies. oxidative stress caused by enhanced production of reactive oxygen species is an important contributor to dox mitochondr...

Objective(s): Arsenic, a toxic metal in drinking water and butyric acid (BA) is a free fatty acid found in many foods. These two can induce oxidative stress in some tissues. The present study investigated the protective effect of metformin against toxicity induced by Arsenic (As) and BA in isolated mice liver mitochondria and pancreatic islets. Materials and Methods: In this study, liver mitoch...
