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

Discoidal recombinant high density lipoproteins (rHDL) of apolipoprotein AI (apoAI) and palmitoyloleoylphosphatidylcholine (POPC), with or without cholesterol, were prepared by cholate dialysis. By gel filtration, rHDL containing 2-4 (Lp2, Lp3 and Lp4) apoAI molecules/particle were obtained. The ApoAI conformation in

Potassium efflux in yeast induced by several cationic compounds showed different characteristics. All of the observed efflux required glucose as substrate at the concentrations used. For most of them, the phenomenon required binding of the cationic compound to the cell

We report the first observation of three photon induced NIR emission (890-1,400 nm) with NIR excitation (800 nm) from a newly synthesized organic neodymium complex with known molecular structure, suggests the potential use of lanthanide probes for use in three-dimensional
RNA (New York, N.Y.), 6(11), 1672-1680 (2000-12-06)
Lanthanide metals such as terbium have previously been shown to be useful for mapping metal-binding sites in RNA. Terbium binds to the same sites on RNA as magnesium, however, with a much higher affinity. Thus, low concentrations of terbium ions
Rare earth elements are vital in everyday life worldwide: catalysts in cars, colors in screens, magnets in electronics. Essential for modern living.
