Arginase appears to be one of the first enzymes which was studied in cell nuclei isolated on a relatively large scale by physicochemical methods. This enzyme was measured in isolated nuclei of liver cells by Behrens (1) who reported that the arginase activity per dry weight of isolated nuclei was about equal to the arginase activity of cytoplasm per dry weight in the case of mammalian liver. It...

background early predictive biomarkers for acute kidney injury (aki) such as neutrophil elatinase-associated lipocalin (ngal) could identify patients who may benefit from early initiation of treatment. objectives we aimed to obtain a cut off point for aki prediction by urine ngal in kidney transplantation. patients and methods in a prospective cohort study, 64 adult who underwent kidney transpl...

the isolated perfused rat liver (iprl) model has been used into toxicology study of rat liver. this model provides an opportunity at evaluation of liver function in an isolated setting. studies showed that cd, in a dose-dependent manner, induced toxic effects in iprl models, and these effects were associated with aminotransferase activity and lipid peroxidation. the aim of this study was to inv...

To address the question of insulin-like growth factor (IGF) I localization and synthesis in kidney, we used two complementary experimental approaches: immunohistochemistry of fixed paraffin-embedded rat kidney sections; and measurement of IGF I mRNA in isolated components of the rat nephron, using a highly sensitive and specific solution hybridization assay. Immunostainable IGF I was localized ...

Skeletal muscle-derived stem/progenitor cells (MDSPCs) have been thoroughly investigated and already used in preclinical studies. However, therapeutic potential of MDSPCs isolated using preplate isolation technique for acute kidney injury (AKI) has not been evaluated. We aimed to characterize rat MDSPCs, compare them with bone marrow mesenchymal stem cells (BM-MSCs), and evaluate the feasibilit...

Northern blot analysis of rat heart mRNA probed with a cDNA coding for the principal polypeptide of rat liver gap junctions demonstrated a 3.0-kb band. This band was observed only after hybridization and washing using low stringency conditions; high stringency conditions abolished the hybridization. A rat heart cDNA library was screened with the same cDNA probe under the permissive hybridizatio...

Objective(s): Populus species have various pharmacological properties, including antioxidant activity. In this study, the effects of Populus tomentiglandulosa extract (PTE) on histopathology and antioxidant enzymes in the rat liver and kidney were examined.  Materials and Methods: Sprague-Dawley rats were assigned to three groups; (1) no...

The major DNA adduct formed from the carcinogen ethylene dibromide (1,2-dibromoethane, EDB) is S-[2-(N7-guanyl)ethyl]glutathione, resulting from the reaction of guanyl residues with the half-mustard S-(2-bromoethyl)glutathione, which is generated by glutathione S-transferase-catalyzed conjugation of EDB with glutathione. The half-life of the alkylating species [putative S-(2-bromoethyl)glutathi...
