Zhang et al. Respond

Reply to Zhang, et al.

TO THE EDITOR—In a recent letter, Zhang et al expressed concerns on our recent report on hypervirulent Klebsiella pneumoniae (hvKP) in China [1, 2]. We would like to address their points of concerns. First, Zhang et al stated that “the genetic relatedness of clinical isolates should be further identified by molecular analysis” [2]. It is generally agreed in publications and clinical practice th...

Response to Zhang et al.

T wo recent reports by Zhang et al published in Nov (2011) and our group (Anand & Kai, 2012; published online in Dec 2011) have suggested a role for the conserved Tudor domain protein encoded by qin as a component of piRNA pathway. Both studies agree that qin plays a role in the piRNA pathway and is required to repress reteroelements but differ in some aspects of their conclusions about qin fun...

Clayton et al. respond.

Lusk et al. respond.

We thank Schimek for his thoughtful letter. We agree that the American Association of State Highway and Transportation Officials (AASHTO) encourages bike paths; however, AASHTO’s definition of a bike path is a shared use path for pedestrians, skaters, wheelchair users, joggers, and other nonmotorized users. AASHTO discourages bicycle-only cycle tracks because, as noted by Schimek, AASHTO discou...

Nanotoxicology: Gangwal et al. Respond

Gangwal et al. (2011) addressed an important topic for nanotoxicology about assessing the toxicity of inhaled nano materials by recom mending relevant concentrations for in vitro toxicity testing. Their efforts to select in vitro concentrations based on reported occupational exposure levels of inhaled nano materials are, indeed, laudable. Their under lying conceptual approach is logical, involv...
