Adaptive evolution of the Hox gene family for development in bats and dolphins.

Bats and cetaceans (i.e., whales, dolphins, porpoises) are two kinds of mammals with unique locomotive styles and occupy novel niches.

Föster resonance energy transfer in solution-processed Si-nanoparticle/carbon nanotube nanocomposites.

By exploiting a simple solution approach, we bound ethoxy-terminated Si nanoparticles to surface functionalized multi-walled carbon nanotubes (MWCNTs) via covalent bonds. Quenching of photoluminescence (PL) of the Si nanoparticles was observed once they were conjugated to the MWCNTs. Analysis of the time-resolved PL decay and calculation indicated that Föster resonance energy transfer from the Si nanoparticles to the MWCNTs may be responsible for the PL quenching.

Crystal structure study on human S100A13 at 2.0 A resolution.

The S100 protein family is the largest group of calcium-binding protein families, which consists of at least 25 members. S100A13, which is widely expressed in a variety of tissues, is a unique member of the S100 protein family. Previous reports showed that S100A13 might be involved in the stress-induced release of some signal peptide-less proteins (such as FGF-1 and IL-1alpha) and also associated with inflammatory functions.
