Clustering of Sex-Biased Genes and Transposable Elements in the Genome of the Medaka Fish Oryzias latipes.

Although genes with similar expression patterns are sometimes found in the same genomic regions, almost nothing is known about the relative organization in genomes of genes and transposable elements (TEs), which might influence each other at the regulatory level. In this study, we used transcriptomic data from male and female gonads of the Japanese medaka Oryzias latipes to define sexually biased genes and TEs and analyze their relative genomic localization. We identified 20,588 genes expressed in the adult gonads of O.

Shear relaxation of imidazolium-based room-temperature ionic liquids.

The frequency-dependent shear viscosities of four representative imidazolium-based room-temperature ionic liquids, 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([bmim][TFSA]), 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF(6)]), 1-hexyl-3-methylimidazolium hexafluorophosphate ([hmim][PF(6)]), and 1-methyl-3-octylimidazolium hexafluorophosphate ([omim][PF(6)]), are measured from 5 to 205 MHz with shear impedance spectroscopy. A relaxation is observed in the measured frequency range in all cases. This is the first report on the shear relaxation of ionic liquids at room temperature, to our best knowledge.
