The influence of serotonergic multilocus genetic variants and parent-child relationship on adolescent creativity.

Objective: Creativity drives both individual progress and societal development. With the development of the gene-environment interaction theory, investigating the physiological and psychological mechanisms underlying creativity has become increasingly essential. Grounded in Bronfenbrenner's ecological systems theory, this study employs the gene-environment (G × E) paradigm to investigate the interaction between serotonin system genes and the parent-child relationship in influencing adolescent creativity.

Stress sensitization to psychological adjustment following childhood adversity: Moderation by serotonergic multilocus genetic variation.

Background: Exposure to adverse childhood experiences may heighten adolescents' sensitivity to stress, which influences their psychological adjustment over their lifetimes. Some research indicates that serotonergic genetic variation moderates how environmental stressors impact psychological adjustment. However, there are recognized limitations in examining gene-environment interactions using only single polymorphisms.

The Relationship Between Family Functioning and Depressive Symptoms in Primary School Children: The Mediating Role of Friendship Quality and the Moderating Role of Teacher-Student Relationship.

Background: This study drew on social ecosystem theory, the comprehensive model of family socialization and the multiple-attachment theory to explore three key aspects: the association between family functioning and depressive symptoms in primary school children, the mediating role of friendship quality and the moderating role of teacher-student relationship in these associations.

Methods: A total of 1024 students in Grades 4 through 6 from five schools in Hunan Province were surveyed using the Short Form of the Center for Epidemiological Studies Depression Scale, the Family Caring Index Questionnaire, the Friendship Quality Questionnaire (FQQ) and teacher-student relationship Subscale of the 'My Class' questionnaire.

Results: (1) Depressive symptoms were significantly negatively correlated with family functioning, friendship quality, and teacher-student relationship.

The Effect of Peer Relationships on Adolescent Loneliness: The Role of Psychological Resilience and the OXTR Gene.

Background: Based on the gene-environment interaction paradigm, this study explored the effect of peer relationships on adolescent loneliness and the role of psychological resilience and the oxytocin receptor gene (OXTR).

Methods: A survey was conducted in a sample of 619 adolescents, and their oral cells were collected for DNA extraction and genotyping.

Results: The results showed that (1) both peer relationships and psychological resilience significantly affected adolescent loneliness; (2) psychological resilience partially mediated the relationship between peer relationships and loneliness in adolescents; (3) OXTR gene rs53576 polymorphism moderated both the first and second half of the indirect pathway of the mediation model.

Effect of In Situ NbC-CrC@graphene/Fe Nanocomposite Inoculant Modification and Refinement on the Microstructure and Properties of W18Cr4V High-Speed Steel.

A novel graphene-coated nanocrystalline ceramic particle, iron-based composite inoculant was developed in this study to optimize the as-cast microstructure and mechanical properties of W18Cr4V high-speed steel (HSS). The effects of the composite inoculant on the microstructure, crystal structure, and mechanical properties of HSS were analyzed using transmission electron microscopy, scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. The (002-) and (020) crystal planes of the FeC and CrC phases, respectively, were collinear at two points in the reciprocal space, indicating a coherent relationship between the FeC and CrC phases in the tempered modified HSS.

Serotonergic multilocus genetic variation moderates the association between interpersonal relationship and adolescent depressive symptoms.

Background: Research suggests that genetic variants linked to serotonin functioning moderate the association between environmental stressors and depressive symptoms, but examining gene-environment interactions with single polymorphisms limits power.

Methods: A multilocus genetic profile score (MGPS) approach to measuring serotonergic multilocus genetic variation and examined interactions with interpersonal relationship, insomnia with depressive symptoms as outcomes in an adolescent sample (average age = 14.15 ± 0.

The relationship between family functioning and psychotic-like experiences of college students: Chain multiple mediating effects.

Aim: To explore the mechanism of the relationship between college students' family functioning and psychotic-like experiences, a chain multi-intermediary model is constructed to investigate the multiple mediating effects of interpersonal adaptation, sleep quality and loneliness on college students' family functioning and psychotic-like experiences.

Methods: Seven hundred seven college students in China were surveyed by using the Family Care Index Questionnaire, Loneliness Scale, Pittsburgh Sleep Quality Index Questionnaire, College Students' Interpersonal Adaptability Subscale and Community Assessment of Psychiatric Experiences.

Results: (a) The detection rate of psychotic-like experiences among college students is 72.

Carbon fibers coated with graphene reinforced TiAl alloy composite with high strength and toughness.

To meet the more rigorous requirement in aerospace industry, recent studies on strengthening and toughening TiAl alloys mostly focus on high Nb addition, which inevitably bring in an increasing of density. In this study, a carbon fibers coated with graphene reinforced TiAl alloy composite was fabricated by powder metallurgy, melt spun and vacuum melting. This composite got remarkable mechanical properties combined with a prominent density reduction.
