Recent advances in the analytical applications of bacterial and firefly luciferases and firefly luciferin are reviewed. Luciferases have been used in soluble and immobilized/co-immobilized forms in assays for a variety of enzymes, substrates, and cofactors. The firefly luciferase reaction forms the
Ophidic accidents are among the problems of public health in Brazil. The components from bothropic venom are responsible for many systemic clinical complications resulting from envenomation. The present work aimed to analyse the systemic changes induced in mice after intraperitoneal administration
A novel nucleic acid hybridization assay with a DNA probe immobilized on 1.25-micron-diameter latex particles was developed. Hybridization of the immobilized probe DNA with sample rRNA was complete in 10 to 15 min. Alkaline phosphatase-labeled anti-DNA-RNA was allowed to bind to the DNA-RNA hybrids
An increased frequency of infections has been reported in patients with chronic liver disease. The tendency of patients in this population to acquire UTI is not completely understood. We aimed at investigating the incidence of UTI in children with cirrhosis, before liver transplantation. Twenty-six
