Endospores are heat-resistant bacterial resting stages that can remain viable for long periods of time and may thus accumulate in sediments as a function of sediment age. The number of spores in sediments has only rarely been quantified, because of
Journal of fluorescence, 17(3), 293-300 (2007-04-19)
Two simple, sensitive and specific fluorimetric methods have been developed for the determination of some sulphur containing compounds namely, Acetylcysteine (Ac), Carbocisteine (Cc) and Thioctic acid (Th) using terbium Tb+3 and uranium U+3 ions as fluorescent probes. The proposed methods

In order to understand the toxic effect of terbium (Tb(III)) on the plant photosynthesis, we investigated the photosynthesis, the ultrastructural structure of chloroplast, the subcellular distribution of horseradish peroxidase (HRP), the activity of HRP, and the content of malondialdehyde in
The possible action of carbon-centered radicals in promoting damage to DNA is explored by generation of the 2-phenylethyl radical. The radical is generated during oxidation of phenelzine (2-phenylethyl hydrazine) by ferricyanide, as well as optically from phenylpropionic acid. Covalent binding
Rare earth elements are vital in everyday life worldwide: catalysts in cars, colors in screens, magnets in electronics. Essential for modern living.
