Silencing urease: a key evolutionary step that facilitated the adaptation of Yersinia pestis to the flea-borne transmission route.
Proc. Natl. Acad. Sci. U. S. A. 111(52) , 18709-14, (2014) The arthropod-borne transmission route of Yersinia pestis, the bacterial agent of plague, is a recent evolutionary adaptation. Yersinia pseudotuberculosis, the closely related food-and water-borne enteric species from which Y. pestis diverged less than 6,400 ... |

Molecular understanding of atmospheric particle formation from sulfuric acid and large oxidized organic molecules.
Proc. Natl. Acad. Sci. U. S. A. 110(43) , 17223-8, (2013) Atmospheric aerosols formed by nucleation of vapors affect radiative forcing and therefore climate. However, the underlying mechanisms of nucleation remain unclear, particularly the involvement of organic compounds. Here, we present high-resolution mass spect... |

Detection of microRNA in tumor cells using exonuclease III and graphene oxide-regulated signal amplification.
ACS Appl. Mater. Interfaces 6(24) , 21780-7, (2014) In this study, we developed a label-free, ultrasensitive graphene oxide (GO)-based probe for the detection of oligonucleotides by laser desorption/ionization mass spectrometry (LDI-MS). On the basis of simple π-π stacking and electrostatic interactions betwee... |
