The link between unhealthy lifestyle behaviors and emotional and behavioral problems in children and adolescents: a latent class analysis.

Unhealthy lifestyle behaviors (ULBs) in children and adolescents are relatively common. Previous studies have shown an association between a single ULBs and emotional and behavioral problems (EBPs); however, few studies have explored the connection between multiple behavioral patterns and EBPs in children and adolescents. Hence, we aimed to investigate the link between ULBs clusters and EBPs among Chinese children and adolescents.

Reversible stability of colloids switched by CO based on polyhexamethylene guanidine.

The stability of a colloid, including emulsion and polymer latex, can be destroyed irreversibly by the addition of salt. Using the CO stimulus, amines can be converted into organic ammonium salts reversibly, which can access the switching of colloids. Polyhexamethylene guanidine (PHMG), was chosen as a switchable amine.
