The authors tested predictions, derived from a self-regulation model, about variables moderating the relationship between level of substance use (tobacco, alcohol, and marijuana) and problems associated with use. Data were from two independent studies of adolescents, with mean ages of 15.4 and 15.5 years (Ns = 1,699 and 1,225). Factor analysis indicated correlated dimensions of control problems and conduct problems. Protective moderation was found for variables indexing good self-control; risk-enhancing moderation was found for variables indexing poor self-control. These effects were generally independent of deviance-prone attitudes and externalizing symptomatology. Multiple-group structural modeling indicated moderation occurred for paths from life stress and coping motives and for paths from level to control and conduct problems. Moderation effects were also found for parental variables, peer variables, and academic competence.

Purpose: Mental health conditions after mild traumatic brain injury (mTBI) are common and can complicate injury outcomes, but are under-treated. According to the Common Sense Model of Self-Regulation, the way patients perceive their health conditions can influence the way they manage them, including if, when, and how they seek treatment. This study explored how individuals perceive persistent symptoms after mTBI, in order to develop a grounded theory about what motivates and demotivates them to seek mental health treatment after their injury.

Background: The neural mechanisms and long-term effects of perceived stress (PS) and self-control (SC) on mental health (MH) are not fully understood. This study seeks to investigate the influence of PS and SC on MH and to identify their neural correlates using fMRI.
Methods: A total of 817 college students participated in behavioral assessments, including the Perceived Stress Scale (PSS), Self-Control Scale (SCS), and Mental Health Continuum Short Form (MHC-SF).

The N6-methyladenine (6mA) modification is an essential epigenetic marker and plays a crucial role in processes, such as DNA repair, replication, gene expression regulation, etc. YerA from Bacillus subtilis is considered a novel class of enzymes capable of catalyzing the deamination of 6mA to produce hypoxanthine. Despite the significance of this type of enzymes in bacterial self-defense systems and potential applications as a gene-editing tool, the substrate specificity, the catalytic mechanism and the physiological function of YerA are currently unclear due to the lack of structural information.

Background: Fatigue and inactivity are linked to decreased health-related quality of life (HRQoL) in chronic conditions. A multidimensional approach to activity pacing may improve HRQoL by promoting physical activity (PA) and alleviating fatigue. Addressing fatigue across chronic conditions is crucial, especially when underlying causes are unknown.
