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

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
