A histidine-rich extension of the mitochondrial F subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria.

Bioenergetic profiles of psychrophiles across domains of life are unusual in that intracellular ATP levels increase with declining temperature. Whole-transcriptome sequencing of the glacier ice worm Mesenchytraeus solifugus revealed a unique C-terminal extension on the ATP6 protein, which forms part of the proton pore of mitochondrial ATP synthase (Complex V). This extension, positioned near the proton exit pore, comprises alternating histidine residues thought to increase proton flux through Complex V leading to elevated ATP synthesis.

The genes are important for growth in the presence of sphingosine by promoting sphingosine metabolism.

Sphingoid bases, including sphingosine, are important components of the antimicrobial barrier at epithelial surfaces where they can cause growth inhibition and killing of susceptible bacteria. is a common opportunistic pathogen that is less susceptible to sphingosine than many Gram-negative bacteria. Here, we determined that the deletion of the operon reduced growth in the presence of sphingosine.

Anticipatory Violence and Health Among Black Adults in the United States.

This study analyzes the relationship between anticipatory community and police violence and health outcomes including mental and physical well-being, sleep problems, and functional disability. Using data from a nationally representative survey of 3015 self-identified Black and African American adults in the USA collected in 2023, findings from a series of regression analyses reveal that anticipating community violence is linked to poorer self-rated health and increased sleep problems. Anticipatory police violence is associated with poorer physical health and sleep disturbances.

Rapid Amplification and Detection of Single-Stranded Nucleic Acids for Point-of-Care Diagnosis.

Nucleic acid detection plays a crucial role in various applications, including disease diagnostics, research development, food safety, and environmental health monitoring. A rapid, point-of-care (POC) nucleic acid test can greatly benefit healthcare system by providing timely diagnosis for effective treatment and patient management, as well as supporting diseases surveillance for emerging pandemic diseases. Recent advancements in nucleic acids technology have led to rapid assays for single-stranded nucleic acids that can be integrated into simple and miniaturized platforms for ease of use.

Perspective: Pseudoscience and the Detection of Marijuana-Based Impairment-We Can and Must Do Better.

Existing tools for making workplace and roadside determinations of marijuana-based impairment are inadequate. They either merely imitate tools used to identify alcohol- based impairment without taking into account important differences between these molecules, or they are pseudoscientific "police science." Legalization of marijuana use must be accompanied by urgent efforts and dedicated funding for the development and implementation of practical, accurate, and objective methods for on-the-spot determination of whether a person is dangerously impaired by marijuana.

Medial prefrontal cortex to nucleus reuniens circuit is critical for performance in an operant delayed nonmatch to position task.

Working memory refers to the temporary retention of a small amount of information used in the execution of a cognitive task. The prefrontal cortex and its connections with thalamic subregions are thought to mediate specific aspects of working memory, including engaging with the hippocampus to mediate memory retrieval. We used an operant delayed-non match to position task, which does not require the hippocampus, to determine roles of the rodent medial prefrontal cortex (mPFC), the nucleus reuniens thalamic region (RE), and their connection.

I am not (your) superwoman, Black girl magic, or beautiful struggle: Rethinking the resilience of Black women and girls.

The concept and social media hashtag, #BlackGirlMagic, is used to demonstrate the ability of Black women and girls to create paths and to succeed despite intersectional racism, sexism, and classism. Conversely, the concept of Black Girl Magic and Strong Black Woman schemas have been used to glorify struggle, undermine support, and victim-blame. Therefore, resiliency for Black women and girls requires clarification on how and why it is used and understood by researchers and practitioners.

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 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.

Portrayals of gun violence victimization and public support for firearm policies: an experimental analysis.

Objectives: This study examines how characteristics of victims and types of incidents described in a media account of gun violence affect public support for three categories of policies that regulate firearms.

Methods: A randomized experiment with a sample of US public ( = 3410).

Results: Victim race, particularly if the victim was Black, was a strong predictor of less public support for all tested categories of firearm regulation.

Demographic differences in perceived effectiveness for policies to prevent school shootings: results from a representative survey in New Jersey.

Objective: To determine what firearm policies New Jersey residents believe will prevent school shootings and the extent to which this varies by sex, firearm ownership status, and political affiliation.

Methods: A representative sample of New Jersey residents (N = 1,018) was collected via the Eagleton Center on Public Interest Polling (ECPIP). Data were weighted to reflect the state's population.

Exploring the Role of Fear, Civic Disengagement, and Economic Disenfranchisement Within Communities that Experience Gun Violence.

A growing body of research has documented how gun violence can affect mental and physical health outcomes among adults. Likewise, the literature is also beginning to reveal negative psychological effects related to distress and hypervigilance and sociological implications around diminished community engagement and economic opportunity. However, there remains a need to fully explore the role of fear related to the experience of gun violence.

Sleep interventions in pediatric oncology: A systematic review of the evidence.

Sleep concerns are common during pediatric cancer treatment and can last into survivorship. The current systematic review sought to identify intervention studies that addressed sleep as a primary or secondary outcome during pediatric cancer treatment up to 5 years after completing treatment. Quality assessment was rated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.

Contextualizing Help-Seeking Attitudes and Help-Seeking Intention: The Role of Superwoman Schema among Black College Women.

Black women are less likely to seek psychological help and underutilize mental health services. Although help-seeking attitudes and intentions are associated in the general population, less is known about this relationship among Black women in college. In this cross-sectional study, we investigated the relationship between help-seeking attitudes and intention among 167 self-identified Black women in college.
