An Open-Source and Highly Adaptable Rodent Limited Bedding and Nesting Apparatus for Chronic Early Life Stress.

Early life stress (ELS) increases susceptibility to cognitive and socioemotional dysfunction by disrupting the neurobiological systems that regulate these behaviors. Animal models provide a valuable tool for investigating the underlying mechanisms, enabling precise manipulation of stress exposure during development. The limited bedding and nesting (LBN) model, which induces maternal stress by restricting access to bedding and nesting materials in rodents, has been instrumental in advancing our understanding of chronic ELS.

Priorities and expectations of researchers, funders, patients and the public regarding equity in medical research and funding: results from the PERSPECT qualitative study.

Background: Considerations of equity in funding and conduct of medical research are receiving greater attention. However, perspectives of diverse stakeholder groups on this topic are poorly characterized. Our study aimed to further understand broad stakeholder perspectives and priorities regarding inequities in medical research and funding, including implications for international collaborations with low-and middle-income countries (LMICs).

Long-Term Impact of Early-Life Stress on Serotonin Connectivity.

Background: Chronic childhood stress is a prominent risk factor for developing affective disorders, yet mechanisms underlying this association remain unclear. Maintenance of optimal serotonin (5-HT) levels during early postnatal development is critical for the maturation of brain circuits. Understanding the long-lasting effects of early-life stress (ELS) on serotonin-modulated brain connectivity is crucial to develop treatments for affective disorders arising from childhood stress.
