background: the major aneuploidies that are diagnosed prenatally involve the autosomal chromosomes 13, 18, and 21, as well as sex chromosomes, x and y. because multiplex ligation-dependent probe amplification (mlpa) is rapid and non-invasive, it has replaced traditional culture methods for the screening and diagnosis of common aneuploidies in some countries. objective:  to evaluate the sensitiv...

The excited-state quantum dynamics of the organic cation in hybrid perovskites are investigated using time-dependent density functional theory. bond fluctuation reveals that energy rela...

Pezier A, Bobkov YV, Ache BW. The Na /Ca exchanger inhibitor, KB-R7943, blocks a nonselective cation channel implicated in chemosensory transduction. J Neurophysiol 101: 1151–1159, 2009. First published December 31, 2008; doi:10.1152/jn.90903.2008. The mechanism(s) of olfactory transduction in invertebrates remains to be fully understood. In lobster olfactory receptor neurons (ORNs), a nonselec...

-The ESR spin probe, TEMPAMINE +, was used to study the interlamellar behavior of adsorbed organic cations on hectorites solvated with water, ethanol, and water-ethanol mixtures, and saturated with several monovalent and divalent metallic cations. The mobility and orientation of the probe was affected greatly by the solvent, and to a lesser extent by the predominant exchangeable cation on the s...
