We construct the most general SO(4,2) hydrogen atom coherent states which are the counterpart of Schr"{o}dinger's harmonic oscillator coherent states. We show that these states cannot be localized and cannot follow the classical orbits. Thus, Schr"{o}dinger's conjecture for the hydrogen atom...
However, developing cells might be promiscuous in their use of transmitter signals, so it is possible that any system that induces membrane depolarization could be used to influence developmental programmes. Abstract In the mature brain, GABA (γ-aminobutyric acid) functions primarily as an inhibitory...
Production of high density lipoprotein (HDL) requires ATP-binding cassette transporter A1 (ABCA1) to drive phospholipid (PL) from the plasma membrane into extracellular apolipoprotein A-I. Here, we use simulations to show that domains of ABCA1 within the
of Vn in ectopic calcium deposition, showed that the HX-domain of Vn can bind both soluble ionic calcium and crystalline HAP with high affinity and chemical specificity [29]. When Pe is crosslinked with DE, the tissue does not calcify throughout the experiment and even for a longer time [...
In the case of the most abundant compound, at Rt 15.5 min, the presence of 2 bromine atoms is deduced from the peak corresponding to molecular ion [M]+• at m/z 300/302/304 (a very weak signal) in the ratio of 1:2:1. The mass spectrum of this compound also shows the base pe...
Among the investigated compounds [(3RS,5SR)-2-methyl-3-pyren-1-ylisoxazolidin-5-yl]methanol (55c), a non-ionic pyrene derivative, exhibited promising cytotoxic and apoptotic properties. The binding of 55c to DNA has been widely investigated using different techniques. UV–Vis experiments...
Intact nuclei were probed with DNAase-I-based probes and the resultant single strand pieces indicate that many or all of the nucleosomes exist in structures that cause every second nucleosome in a series to be resistant to attack. The effect is observed with chicken erythrocyte nuclei, rat liver...
(SI). New units are invented when existing units are inadequate. For example, chemical reactions often take place at levels where usinggramswouldn't make sense, yet using absolute numbers of atoms, molecules, or ions would be confusing, too. So, scientists invented the mole to bridge the ...
