Do relationships with parents determine citizens' reactions to war trauma?

Background: The article concerns the psychology of trauma: the intensity of the experienced threats and reactions to the trauma in the form of post-traumatic stress disorder (PTSD), defenses and post-traumatic growth (PTG) in Ukrainian immigrants in Poland. The issues of trauma psychology were studied in connection with the relationships with parents.

Participants And Procedure: The methods used mainly concerned the specifics of experiencing strong threats (trauma) and responding to them (PCL-5 questionnaire, Psycho-Social and Psychic Defenses Questionnaire, Post-Traumatic Growth Inventory), determination of closeness to parents (Scale of Closeness to Biological Parents) and secure and non-secure attachment style (Attachment Style Questionnaire).

Structural analysis of the stable form of fibroblast growth factor 2 - FGF2-STAB.

Fibroblast growth factor 2 (FGF2) is a signaling protein that plays a significant role in tissue development and repair. FGF2 binds to fibroblast growth factor receptors (FGFRs) alongside its co-factor heparin, which protects FGF2 from degradation. The binding between FGF2 and FGFRs induces intracellular signaling pathways such as RAS-MAPK, PI3K-AKT, and STAT.

Functional characterization of luciferase in a brittle star indicates parallel evolution influenced by genomic availability of haloalkane dehalogenase.

Determining why convergent traits use distinct versus shared genetic components is crucial for understanding how evolutionary processes generate and sustain biodiversity. However, the factors dictating the genetic underpinnings of convergent traits remain incompletely understood. Here, we use heterologous protein expression, biochemical assays, and phylogenetic analyses to confirm the origin of a luciferase gene from haloalkane dehalogenases in the brittle star .

The vast majority of somatic mutations in plants are layer-specific.

Background: Plant meristems are structured organs consisting of distinct layers of stem cells, which differentiate into new plant tissue. Mutations in meristematic layers can propagate into large sectors of the plant. However, the characteristics of meristematic mutations remain unclear, limiting our understanding of the genetic basis of somaclonal phenotypic variation.

Identification of new endocrine disruptive transthyretin ligands in polluted waters using pull-down assay coupled to non-target mass spectrometry.

Surface and treated wastewater are contaminated with highly complex mixtures of micropollutants, which may cause numerous adverse effects, often mediated by endocrine disruption. However, there is limited knowledge regarding some important modes of action, such as interference with thyroid hormone (TH) regulation, and the compounds driving these effects. This study describes an effective approach for the identification of compounds with the potential to bind to transthyretin (TTR; protein distributing TH to target tissues), based on their specific separation in a pull-down assay followed by non-target analysis (NTA).
