Previously we have reported that Legionella pneumophila can mediate plasmid DNA transfer at a frequency of about 10(-3) transconjugants per donor and that this process is dependent on several icm genes. Here we characterize the icm-dependent conjugal ability of L. pneumophila and study its relationship to intracellular multiplication and host cell killing. We found that three icm genes and the ...

Cellular response of inorganic nanoparticles (NPs) is strongly dependent on their surface chemistry. By taking advantage of robust single-particle fluorescence and giant Raman enhancements of unique polycrystalline silver NPs (AgNPs), we quantitatively investigated effects of two well-known surface chemistries, passive PEGylation and active c-RGD peptide conjugation, on in vitro behaviors of Ag...

gabapentin (gbp) is one of the new antiepileptic drugs (aeds) applied extensively in neurology and psychiatry. the advantage of new aeds includes newer mechanism of action, broad spectrum of anti-seizure effects, lesser drug interactions and fewer side effects. gbp is a cyclized analogue of gaba but it does not interact with gaba receptors, nor does it inhibit gaba uptake or prevent the degener...

Although the entry of DNA into the nucleus is a crucial step of non-viral gene delivery, fundamental features of this transport process have remained unexplored. This study analyzed the effect of linear double stranded DNA size on its passive diffusion, its active transport and its NLS-assisted transport. The size limit for passive diffusion was found to be between 200 and 310 bp. DNA of 310-15...

We investigate the phase behavior and kinetics of a monodisperse mixture of active (i.e., self-propelled) and passive isometric Brownian particles through Brownian dynamics simulations and theory. As in a purely active system, motility of the active component triggers phase separation into a dense and a dilute phase; in the dense phase, we further find active-passive segregation, with "rafts" o...
