Abstract The possible effects of wastewater treatment products on mussels (Mytilus galloprovincialis) were studied. Three common pollution biomarkers used: neutral red retention assay, malondialdehyde contents and DNA damage through comet assay. Two groups treated in the laboratory for 25 days with 20 40 %v/v collected after chlorination, control formed a third group. results showed statistical...

The present study was aimed to enzymatic antioxidants (superoxide dismutase, catalase, polyphenol oxidase), nonenzymatic (saponin, flavonoids, ascorbic acid and tannin), anti-oxidant ability assays (total anti-oxidant, hydroxyl radical scavenging ability, reducing power activity, inhibition of lipid peroxide formation, DPPH activity metal chelating assay) in I. marginata leaves whole plant. res...

The formation of amyloid assemblies is associated with major human disorders. Yet no therapeutic agents presently exist to control this process. In a recent paper, a new bacterial system is described that uses a fusion of the Alzheimer's disease beta-amyloid polypeptide to the GFP. The assay detects the formation of small, soluble amyloid intermediates associated with degenerative diseases. Thi...

Amyloid fibrils are the most distinct components of the plaques associated with various neurodegenerative diseases. Kinetic studies of amyloid fibril formation shed light on the microscopic mechanisms that underlie this process as well as the contributions of internal and external factors to the interplay between different mechanistic steps. Thioflavin T is a widely used noncovalent fluorescent...

Because botulinum toxin is a bacterial antigen, the therapy with this biological bears the risk that the formation of antibodies is elicited which can neutralize the neurotoxin. Several factors have an impact on this immune response. There are (unknown) patientrelated factors but also the dose, the injection interval and the purity of the product play a role in the formation of antibodies. Seve...
