This study examined the relationships of adolescents' perceptions of parental and peer behaviors with cigarette and alcohol use in different neighborhood contexts. The sample included 924 adolescents (49% boys, 51% girls) 12-14 years of age whose addresses were matched with 1990 census block groups. Six neighborhood types were identified through a cluster analysis. The findings suggest that parental smoking was associated with increased adolescent smoking in suburban white middle socioeconomic status (SES) neighborhoods. Peer smoking was associated with increased adolescent smoking in rural neighborhoods. Parental monitoring was associated with decreased adolescent drinking in urban white high-SES neighborhoods and parental drinking was associated with increased adolescent drinking in urban white middle-SES neighborhoods, respectively. Peer drinking was associated with increased adolescent drinking in urban neighborhoods. This study demonstrates the importance of examining parental and peer influences on adolescent smoking and drinking in different neighborhood contexts.

In plasma, the zymogens factor XII (FXII) and prekallikrein reciprocally convert each other to the proteases FXIIa and plasma kallikrein (PKa). PKa cleaves high-molecular-weight kininogen (HK) to release bradykinin, which contributes to regulation of blood vessel tone and permeability. Plasma FXII is normally in a "closed" conformation that limits activation by PKa.

Background: Transitional-aged youth have a high burden of mental health difficulties in Canada, with Indigenous youth, in particular, experiencing additional circumstances that challenge their well-being. Mobile health (mHealth) approaches hold promise for supporting individuals in areas with less access to services such as Northern Ontario.
Objective: The primary objective of this study is to evaluate the effectiveness of the JoyPop app in increasing emotion regulation skills for Indigenous transitional-aged youth (aged 18-25 years) on a waitlist for mental health services when compared with usual practice (UP).

Background: Few studies have explored the relationship between macronutrient intake and sleep outcomes using daily data from mobile apps.
Objective: This cross-sectional study aimed to examine the associations between macronutrients, dietary components, and sleep parameters, considering their interdependencies.
Methods: We analyzed data from 4825 users of the Pokémon Sleep and Asken smartphone apps, each used for at least 7 days to record objective sleep parameters and dietary components, respectively.

While social support benefits those in treatment for opioid use disorder, it is unclear how social support impacts patient outcomes. This study examines how support person attitudes toward buprenorphine and their communication about substance use are associated with the well-being of patients receiving buprenorphine treatment. We analyzed cross-sectional baseline data from 219 buprenorphine patients (40% female) and their support persons (72% female).

This study delves into the adverse effects of AVM, emphasizing oxidative stress induction in the Chinese mitten crab, , and the role of the MAPK-CncC signaling pathway in mediating the antioxidative response. Our findings reveal a dose-dependent impairment in growth performance, alongside occurrence of oxidative stress. The activity of CAT and superoxide dismutase increased significantly in all treatments (0.
