Pseudofracture, a reproducible murine model of sterile musculoskeletal trauma, allows for evaluation of late term post-traumatic immune responses. This article describes the procedural execution of the model step by step, including the potential for experimental model combinations to permit study of multiple trauma.

We present a protocol of personalized script-driven trauma-related imagery and clinical assessments within a comparison design for investigating peritraumatic dissociation (PD), psychophysiological reactions, i.e. heart rate (HR) and skin conductance (SC), and psychological features of often severely traumatized individuals with borderline personality disorder (BPD).

Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics. Together, the fossil...

Trauma-related stress can activate both the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis. These systems coordinate a biological stress response that includes release of hormones such as cortisol. Their activation can influence immune, neural, and metabolic activity, giving researchers a mechanistic link between an experienced event and measurable changes in organismal function.
Repeated or severe exposure may do more than produce a short-lived response. It can contribute to persistent alterations in stress regulation, inflammation, behavior, and gene expression. Examining these domains together helps biology researchers consider how the intensity or recurrence of past events may relate to longer-lasting differences in health and function.
Epigenetic modification is relevant because it is identified as one mechanism through which trauma-related exposure may be associated with altered gene expression. Studying this relationship can help explain how environmental experiences are connected to biological variation and long-term outcomes, while keeping gene expression within a broader network of stress-related changes.
A documented trauma history supplies context for biological measurements that might otherwise appear unrelated or unexplained. By considering past physical, psychological, or environmental events alongside observed variation, researchers can investigate risk factors for disease and evaluate how experiences may relate to changes in stress regulation, inflammation, neural activity, or metabolism.
Investigators can use Trauma History to examine how early-life and environmental conditions shape long-term outcomes. Relevant outcomes include persistent differences in stress regulation, immune or inflammatory activity, behavior, metabolism, and gene expression. This approach also supports research into disease risk by connecting documented experiences with patterns of biological variation.
Recording whether an event was physical, psychological, or environmental makes the history more specific for subsequent interpretation. The documented category can be considered alongside biological findings involving stress regulation, immune activity, neural function, metabolism, behavior, or gene expression. This preserves contextual detail when researchers or clinicians evaluate variation and health-related outcomes.
