The behaviour of adenine and 2’-deoxyadenosine-5’-monophosphate (dAMP) at positive surface potentials of a silver working electrode was investigated using surface-enhanced Raman scattering (SERS). The use of positive potentials in the presence of adenine or dAMP leads to a rapid accumulation of an intense spectrum. It is proposed that complexes of adenine (dAMP) with silver generate the observe...

AIMS To analyse the contribution of certain social, familial, prenatal, perinatal, and developmental background factors in the pathogenesis of deficits in attention, motor control, and perception (DAMP). METHODS A population based case-control study was carried out with 113 children aged 6 years, 62 diagnosed with DAMP and 51 controls without DAMP. The children's health and medical records we...

Immunocytochemical localization of DAMP, a reagent used to detect low pH intracellular compartments, was studied in cultured neurons from rat hippocampus and in frog retinas. We find that DAMP is more sharply localized and that the immunocytochemical reaction is stronger when horseradish peroxidase or other proteins are included in the medium used to administer DAMP to the cells. A likely expla...

Cholesterol-rich regions are attractive targets for studying metabolic disorders that involve accumulation of cholesterol. Despite efforts to develop probes for labelling cholesterol-rich regions in cells, few of these reagents have a low molecular weight. Previous studies have shown that the acidotropic pH indicator, N-{3-[(2,4-dinitrophenyl)amino]propyl}-N-(3-aminopropyl)methylamine dihydroch...
