In this study, the cytogenetic effects of a sulphonylurea group herbicide Logran (effective substance; Triasulfuron) were investigated in human peripheral blood lymphocyte culture. The cultures were treated with 2, 4, 8, 16, 32, 64, 128, and 256 mg/ml concentrations of Logran for 24 and 48 h. This compound increased chromosome aberrations (CA) in human lymphocyte culture. Logran decreased Mitot...

Background: Acute poisonings are common presentations to emergency departments (EDs) worldwide and require rapid assessment. Consultant emergency physicians (EPs) faced with various toxicological presentations must initiate rapid investigations and empirical management. This study aimed to determine emergency department doctors’ level of knowledge and confidence in toxicological presentations, ...

The TyrR protein of Escherichia coli K12 is a homodimer containing 513 amino acids/subunit. This protein is important in the transcriptional regulation of several genes whose protein products catalyze steps in aromatic amino acid biosynthesis or transport. Methods were developed for efficiently purifying the TyrR protein to apparent homogeneity. We analyzed the pattern of cleavage of the TyrR p...
