The interaction of methylene violet (MV) and 4-bromomethylene violet (BrMV) with calf thymus and supercoiled phi X174 phage RF I DNA is reported. Measurements employing UV-visible absorption spectroscopy and equilibrium dialysis give evidence for the formation of complexes by each
A fairly sensitive spectrophotometric method for the determination of ibuprofen, ketoprofen, piroxicam, diclofenac sodium, mefenamic acid or enfenamic acid in bulk samples and pharmaceutical preparations is described, based on the formation of a chloroform-soluble, coloured ion-association complex between the drug
Photochemistry and photobiology, 65(3), 451-455 (1997-03-01)
Previous studies with methylene blue (MB) in red cell suspensions have demonstrated that extracellular, but not intracellular, virus can be readily photoinactivated. To test if the resistance of intracellular virus to inactivation is related to the permanent positive charge of

Selective and sensitive methods for the determination of the cationic dye and anti-malarial methylene blue in human liquid whole blood, dried whole blood (paper spot), and plasma depending on protein precipitation and cation exchange chromatography coupled to electrospray ionisation (ESI)
Chronological lifespan may be defined as the result of accumulation of irreversible damage to intracellular components during extended stationary phase, compromising cellular integrity and leading to death and autolysis. In contrast, replicative lifespan relates to the number of divisions an
