Background: Racial discrimination (RD) disrupts regulatory systems in minoritized individuals, particularly those that govern attention, including attention to visceral signals (interoception). RD frequency is linked to physiological "shut down" responses, characterized clinically by dissociation. We examined associations between RD frequency and functional connectivity of attention and interoceptive networks in sample of trauma-exposed Black women, investigating how connectivity alterations associate with dissociation severity.

Alga-dominated geothermal spring communities in Yellowstone National Park (YNP), USA, have been the focus of many studies, however, relatively little is known about the composition and community interactions which underpin these ecosystems. Our goal was to determine, in three neighboring yet distinct environments in Lemonade Creek, YNP, how cells cope with abiotic stressors over the diurnal cycle. All three environments are colonized by two photosynthetic lineages, and , both of which are extremophilic Cyanidiophyceae red algae.

Objective: In 2017, Australian's National Cervical Screening Program changed from 2-yearly cytology to 5-yearly primary human papillomavirus (HPV) testing. The Stakeholder Opinions of Renewal Implementation and Experiences Study (STORIES) aimed to capture stakeholder perspectives during implementation of the renewed National Cervical Screening Program.

Materials And Methods: Qualitative semistructured interviews were conducted with key National Cervical Screening Program stakeholders 11-20 months following the change, either face-to-face, online, or via phone.

Meditation is a family of ancient and contemporary contemplative mind-body practices that can modulate psychological processes, awareness, and mental states. Over the last 40 years, clinical science has manualised meditation practices and designed various meditation interventions (MIs), that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past decade, neuroimaging has examined the neuroscientific basis of meditation practices, effects, states, and outcomes for clinical and non-clinical populations.

Article Synopsis
  • - This study investigates the relationship between dissociation, a common trauma response, and the microstructure of white matter (WM) in the brain, particularly looking at how brain connectivity may be affected in trauma-exposed women.
  • - Researchers analyzed data from 135 women to examine how different facets of dissociation related to fractional anisotropy (FA), a measure of WM integrity, finding significant negative correlations between FA and overall dissociation across several important brain tracts.
  • - The results suggest that greater severity of dissociation is associated with reduced WM integrity in areas linked to sensory processing, emotional regulation, and memory, highlighting potential targets for therapy and neuromodulation interventions.
