Racial Discrimination-related Interoceptive Network Disruptions: A Pathway to Disconnection.

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.

Temporal dynamics in a red alga dominated geothermal feature in Yellowstone National Park.

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.

How Does Transitioning to Primary Human Papillomavirus Screening Impact Colposcopy Services? Lessons From an Australian National Program.

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.

ENIGMA-Meditation: Worldwide Consortium for Neuroscientific Investigations of Meditation Practices.

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 manualized meditation practices and designed various meditation interventions that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past decade, neuroimaging has been used to examine the neuroscientific basis of meditation practices, effects, states, and outcomes for clinical and nonclinical populations.

Metalloproteomics Reveals Multi-Level Stress Response in When Exposed to Arsenite.

The operon encodes a three-protein arsenic resistance system. ArsR regulates the transcription of the operon, while ArsB and ArsC are involved in exporting trivalent arsenic and reducing pentavalent arsenic, respectively. Previous research into 5A has demonstrated that ArsR has regulatory control over a wide range of metal-related proteins and metabolic pathways.

Hot springs viruses at Yellowstone National Park have ancient origins and are adapted to thermophilic hosts.

Geothermal springs house unicellular red algae in the class Cyanidiophyceae that dominate the microbial biomass at these sites. Little is known about host-virus interactions in these environments. We analyzed the virus community associated with red algal mats in three neighboring habitats (creek, endolithic, soil) at Lemonade Creek, Yellowstone National Park (YNP), USA.

Impact of room acoustics and visual cues on speech perception and talker localization by children with mild bilateral or unilateral hearing loss.

Introduction: This study evaluated the ability of children (8-12 years) with mild bilateral or unilateral hearing loss (MBHL/UHL) listening unaided, or normal hearing (NH) to locate and understand talkers in varying auditory/visual acoustic environments. Potential differences across hearing status were examined.

Methods: Participants heard sentences presented by female talkers from five surrounding locations in varying acoustic environments.

Pediatric focal calvarial lesions: an illustrated review.

Focal skull lesions in children can be diagnostically challenging with a wide variety of potential etiologies. Understanding the diverse pathologies and recognizing their associated clinical and imaging characteristics is crucial for accurate diagnosis and appropriate treatment planning. We review pertinent anatomy of the scalp and calvarium and review different pathologies that can present with focal skull lesions in pediatric patients.

Aerobic methane synthesis and dynamics in a river water environment.

Reports of aerobic biogenic methane () have generated new views about sources in nature. We examine this phenomenon in the free-flowing Yellowstone river wherein concentrations were tracked as a function of environmental conditions, phototrophic microorganisms (using chlorophyll , Chl , as proxy), as well as targeted methylated amines known to be associated with this process. was positively correlated with temperature and Chl , although diurnal measurements showed concentrations were greatest during the night and lowest during maximal solar irradiation.

Implementation of Australia's primary human papillomavirus (HPV) cervical screening program: The STakeholders Opinions of Renewal Implementation and Experiences Study.

In this study, we aimed to document stakeholders' experiences of implementing Australia's renewed National Cervical Screening Program. In December 2017, the program changed from 2nd yearly cytology for 20-69 year olds to 5 yearly human papillomavirus (HPV) screening for women 25-74 years. We undertook semi-structured interviews with key stakeholders including government, program administrators, register staff, clinicians and health care workers, non-government organisations, professional bodies, and pathology laboratories from across Australia between Nov 2018 - Aug 2019.

'I'm a bit of a champion for it actually': qualitative insights into practitioner-supported self-collection cervical screening among early adopting Victorian practitioners in Australia.

Background: Self-collection for cervical screening has been available in the Australian National Cervical Screening Program since 2017 and is now available to all people as an option for cervical screening through a practitioner-supported model. Documenting early adopting practitioner experiences with self-collection as a mechanism to engage people in cervical screening is crucial to informing its continuing roll-out and implementation in other health systems.

Aim: This study aimed to describe the experiences of practitioners in Victoria, Australia, who used human papillomavirus (HPV)-based self-collection cervical screening during the first 17 months of its availability.

Revised classification of the Cyanidiophyceae based on plastid genome data with descriptions of the Cavernulicolales ord. nov. and Galdieriales ord. nov. (Rhodophyta).

The Cyanidiophyceae, an extremophilic red algal class, is distributed worldwide in extreme environments. Species grow either in acidic hot environments or in dim light conditions (e.g.

-Key Stakeholder Perspectives on the Initial Implementation of Self-Collection in Australia's Cervical Screening Program: A Qualitative Study.

Background: In December 2017, the Australian National Cervical Screening Program transitioned from 2-yearly cytology-based to 5-yearly human papillomavirus (HPV)-based cervical screening, including a vaginal self-collection option. Until July 2022, this option was restricted to under- or never-screened people aged 30 years and older who refused a speculum exam. We investigated the perspectives and experiences of stakeholders involved in, or affected by, the initial implementation of the restricted self-collection pathway.

Arsenic and Mercury Distribution in an Aquatic Food Chain: Importance of Femtoplankton and Picoplankton Filtration Fractions.

Arsenic (As) and mercury (Hg) were examined in the Yellowstone Lake food chain, focusing on two lake locations separated by approximately 20 km and differing in lake floor hydrothermal vent activity. Sampling spanned from femtoplankton to the main fish species, Yellowstone cutthroat trout and the apex predator lake trout. Mercury bioaccumulated in muscle and liver of both trout species, biomagnifying with age, whereas As decreased in older fish, which indicates differential exposure routes for these metal(loid)s.

Global exposure to flood risk and poverty.

Flooding is a pervasive natural hazard, with new research demonstrating that more than one in five people around the world live in areas directly exposed to 1-in-100 year flood risk. Exposure to such flood risk is particularly concentrated amongst lower income households worldwide.

Self-regulation of the posterior cingulate cortex with real-time fMRI neurofeedback augmented mindfulness training in healthy adolescents: A nonrandomized feasibility study.

Mindfulness training (MT) promotes the development of one's ability to observe and attend to internal and external experiences with objectivity and nonjudgment with evidence to improve psychological well-being. Real-time functional MRI neurofeedback (rtfMRI-nf) is a noninvasive method of modulating activity of a brain region or circuit. The posterior cingulate cortex (PCC) has been hypothesized to be an important hub instantiating a mindful state.
