Objective.The comparative analysis of the structure of the regulatory gene vasH of the type VI secretion system and its expression in toxigenic and non-toxigenic V.cholerae O1, biovar El Tor strains.Materials and methods.We used 35 strains isolated from patients and from the environmental samples in the territory of Russia and Ukraine between 1970
Combining respondent-driven sampling with a community-based participatory action study of people who smoke drugs in two cities in British Columbia, Canada
Abstract Background The smoking of illicit drugs presents a serious social and economic burden in Canada.People who smoke drugs (PWSD) are at increased risk of contracting multiple infections through risky drug practices.Peer-led harm reduction activities, and the resulting social networks that form around them, can potentially minimize the dangers
Bifurcation and controller design in a 3D delayed predator-prey model
Delayed dynamical models demonstrate significant application value in depicting interactions and internal dynamics among different biological populations.Therefore, they have garnered significant interest from numerous scholars in both Coats biology and mathematics.Based on previous studies, this article construct a novel delayed predator-prey mode
Coordination of matrix attachment and ATP-dependent chromatin remodeling regulate auxin biosynthesis and Arabidopsis hypocotyl elongation.
Hypocotyl elongation is extensively controlled by hormone signaling networks.In particular, auxin metabolism and signaling play key roles in Coats light-dependent hypocotyl growth.The nuclear matrix facilitates organization of DNA within the nucleus, and dynamic interactions between nuclear matrix and DNA are related to gene regulation.Conserved sc
