Species-specific satellite DNA composition dictates formation of PRC1-mediated pericentric heterochromatin.

Pericentromeres are heterochromatic regions adjacent to centromeres that ensure accurate chromosome segregation. Despite their conserved function, they are composed of rapidly evolving A/T-rich satellite DNA. This paradoxical observation is partially resolved by epigenetic mechanisms that maintain heterochromatin, independent of specific DNA sequences.

The Role of the Built Environment in the Community Participation of Adults Aging With Long-Term Physical Disabilities: A Scoping Review.

The purpose of this scoping review was to characterize the nature and scope of existing literature on the role of built environments in the community participation of adults aging with physical disabilities (AAwPD). A scoping review was selected to identify the volume and types of evidence available, pinpoint knowledge gaps, and clarify key concepts. Twenty-one articles were included for review, all of which were published within the last 20 years and identified components of the built environment for intervention.

Is it worth it? Greater risk aversion with lower life satisfaction among depressed individuals.

Decisions of individuals with depression are often risk-averse. Risk-aversion may also extend to decisions regarding treatment, which may cause individuals to forgo or delay treatment. It is also well established that depression is associated with lower satisfaction with life.

Uses and Gratifications of Music in Bereavement: A Qualitative Inquiry.

This study investigates the role of music during bereavement. Music plays a role in peoples' bereavement experiences and gets associated with numerous memories. Despite widespread recognition of the importance of music, little research has considered what bereaved individuals "gain" through their musical selections.

The impact of neurofeedback training on children with developmental trauma: A randomized controlled study.

Objective: Developmental trauma or chronic early childhood exposure to abuse and neglect by caregivers has been shown to have a long-lasting pervasive impact on mental and neural development, including problems with attention, impulse control, self-regulation, and executive functioning. Its long-term effects are arguably the costliest public health challenge in the United States. Children with developmental trauma rarely have a satisfactory response to currently available evidence-based psychotherapeutic and pharmacological treatments.
