A range of new cyanine dyes has been prepared and characterised. These dyes are more conveniently synthesised by the reaction of two heterocyclic quaternary salts. The dyes contain a purine heterocycle coupled to an aro-(thia-, selena-, oxa-, imida)z

Management and control of malaria allows epidemiological studies. Microscopic examination of blood films is actually the most rapid and accurately method for diagnosis malaria. Malaria parasites can be stained with many dyes, while Romanowsky-type st

The high degree of selectivity observed in the incorporation of phenylpropanoids into lignin may be a consequence of the influence exerted by methoxyl substituents on the ambident radicals generated during biosynthesis. Since unpaired electron distri

γ-Irradiation of food is known to cause destruction of vitamins. However, the reactions involved have not been fully elucidated. Accordingly, several powdered vitamins have been γ-irradiated and the free radicals formed spin trapped by dissolution
