BACKGROUND: &amp;#945;-Farnesene is a volatile sesquiterpene synthesized by the plant mevalonate (MVA) pathway through the action of &amp;#945;-farnesene synthase. The &amp;#945;-farnesene synthase 1 (MdAFS1) gene was isolated from apple peel (var. white winterpearmain), and transformed into tobacco (Nicotiana tabacum NC89). The transgenic plants had faster stem elongation during vegetative growth and earlier flowering than wild type (WT). Our studies focused on the transgenic tobacco phenotype. RESULTS: The levels of chlorophyll and soluble protein decreased and a lower seed biomass and reduced net photosynthetic rate (Pn) in transgenic plants. Reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) and superoxide radicals (O2._) had higher levels...

The aim of this meta-analysis was to compare the efﬁcacy of metronidazole and vancomycin for the treatment of Clostridium difﬁcileinfection, especially to investigate which agent was superior for treating either mild or severe C. difﬁcileinfection. A meta-analysis of randomized controlled trials and cohort studies identiﬁed in Pubmed, Embase, and the Cochrane Library was conducted. Four randomized controlled trials and two cohort studies involving 1218 patients were included in this meta-analysis. Metronidazole was inferior to vancomycin for treating C. difﬁcileinfection in terms of both initial clinical cure rates (risk ratio, RR = 0.91, 95% conﬁdence interval, CI = 0.84-0.98, p= 0.02) and sustained cure rates (RR = 0.88, 95% CI = 0.82-0.96, p= 0.003)....
