The current study investigated caregiver emotion regulation (ER) as a familial factor contributing to youth ER and risk for psychopathology following stressful life events.

Adolescent-Mother Attachment and Dyadic Affective Processes: Predictors of Internalizing and Externalizing Symptoms.

Given that adolescence is a critical period for socioemotional development, marked by shifting dynamics in the parent-child relationship, parent-adolescent dyadic regulation may serve as a key mechanism linking the quality of the parent-adolescent relationship to adolescent mental health. The current study investigated two dyadic regulatory processes during mother-adolescent conflictual interactions as interpersonal mechanisms underlying the link between adolescent-mother attachment security and adolescents' internalizing and externalizing symptoms: (a) mutual engagement in positive affect (i.e.

Group-Based Interventions in Lifestyle Medicine.

Group-based interventions in health care have demonstrated a positive influence on patient outcomes by strengthening patient-healthcare professional relationships and providing an avenue for patient empowerment through shared experiences and belongingness. Groups have been shown to enhance social and psychological support, improve self-management behaviors, and encourage peer-support. However group settings also present challenges, such as discomforts in sharing within a group context and managing diverse group dynamics.

Alterations in fear learning as a mechanism linking childhood exposure to violence with PTSD symptoms: a longitudinal study.

Background: Fear learning is a core component of conceptual models of how adverse experiences may influence psychopathology. Specifically, existing theories posit that childhood experiences involving childhood trauma are associated with altered fear learning processes, while experiences involving deprivation are not. Several studies have found altered fear acquisition in youth exposed to trauma, but not deprivation, although the specific patterns have varied across studies.

expHRD: an individualized, transcriptome-based prediction model for homologous recombination deficiency assessment in cancer.

Background: Homologous recombination deficiency (HRD) stands as a clinical indicator for discerning responsive outcomes to platinum-based chemotherapy and poly ADP-ribose polymerase (PARP) inhibitors. One of the conventional approaches to HRD prognostication has generally centered on identifying deleterious mutations within the BRCA1/2 genes, along with quantifying the genomic scars, such as Genomic Instability Score (GIS) estimation with scarHRD. However, the scarHRD method has limitations in scenarios involving tumors bereft of corresponding germline data.

Variations in Student Approaches to Problem Solving in Undergraduate Biology Education.

Existing research has investigated student problem-solving strategies across science, technology, engineering, and mathematics; however, there is limited work in undergraduate biology education on how various aspects that influence learning combine to generate holistic approaches to problem solving. Through the lens of situated cognition, we consider problem solving as a learning phenomenon that involves the interactions between internal cognition of the learner and the external learning environment. Using phenomenography as a methodology, we investigated undergraduate student approaches to problem solving in biology through interviews.

TXNIP-mediated crosstalk between oxidative stress and glucose metabolism.

Thioredoxin-interacting protein (TXNIP) has emerged as a key player in cancer and diabetes since it targets thioredoxin (TRX)-mediated redox regulation and glucose transporter (GLUT)-mediated metabolism. TXNIP consists of two arrestin (ARR, N-ARR and C-ARR) domains at its amino-terminus and two PPxY (PY) motifs and a di-leucine (LL) motif for endocytosis at its carboxyl-terminus. Here, we report that TXNIP shuffles between TRX and GLUTs to regulate homeostasis of intracellular oxidative stress and glucose metabolism.
