A rapid microprocedure for isolating detergent (sodium N-lauroyl sarcosinate)-insoluble major outer membrane proteins from Haemophilus species produced results qualitatively identical to those obtained with a commonly used preparative isolation procedure. Proteins isolated by both procedures were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis after staining with Coomassie...

BACKGROUND Prion diseases are fatal neurodegenerative disorders with no effective therapy currently available. Accumulating evidence has implicated over-activation of P2X7 ionotropic purinergic receptor (P2X7R) in the progression of neuronal loss in several neurodegenerative diseases. This has led to the speculation that simultaneous blockade of this receptor and prion replication can be an eff...

Laccase is a blue multi-copper oxidase. It has a broad biotechnical potential which increases the interest to study the enzyme further. A laccase-encoding gene from the white-rot fungus Trametes versicolor (lcc2) was mutated using two different methods for random mutagenesis: error-prone PCR and a method based on an E. coli strain (ES1301 mutS) that introduces random mutations. For the error-pr...

We report intensely staining epiretinal membrane (ERM) with Brilliant Blue G (BBG) under air for two minutes. ERM peeling was performed in 21 cases. After removal of posterior hyaloid, 0.2 mL BBG was first applied on the macula, to stain ERM under air conditions for 2 minutes. Internal limiting membrane (ILM) was intensely stained and peeled in all cases following ERM removal. In 4 cases, the E...

To determine the effect of membrane brightness on multifocal electroretinograms (mfERGs), we implanted poly lactic-co-glycolic acid (PLGA) membranes in the subretinal space of 11 porcine eyes. We compared membranes with their native shiny white color with membranes that were stained with a blue dye (Brilliant Blue). Histological and electrophysiological evaluation of the overlying retina was ca...

Industrial wastewater including dye waste disposal, has been released in a massive amount and is difficult to degrade, especially synthetic dyes. In this study, 10 different types of fungi were isolated from decayed wood UTM forest labelled as S1-S10. Two dyes chosen for which Procion Red MX-5B (PRMX5B) Remazol Brilliant Violet 5R (RBV5R). These screened their ability decolor both further teste...
