For individuals with Duchenne or Becker muscular dystrophy (DMD and BMD, respectively), transitioning to adulthood presents significant challenges. Although considerable attention has been given to facilitating medical transitions due to the complexity of these conditions, less focus has been placed on other aspects of the transition, such as achieving independence. This study assessed the transition needs of people with DMD or BMD, exploring various domains including health, education, employment, living arrangements, transportation, daily activities, and independent personal life.

Trait mindfulness refers to one's disposition or tendency to pay attention to their experiences in the present moment, in a non-judgmental and accepting way. Trait mindfulness has been robustly associated with positive mental health outcomes, but its neural underpinnings are poorly understood. Prior resting-state fMRI studies have associated trait mindfulness with within- and between-network connectivity of the default-mode (DMN), fronto-parietal (FPN), and salience networks.

Objectives: People with idiopathic hypersomnia report significant impairment in their lives due to idiopathic hypersomnia symptoms, and this likely includes an impact on social relationship health. This study investigated the effects of idiopathic hypersomnia on social relationships (friends, romantic, and sexual) during the key developmental period of young adulthood.

Methods: Young adults (N = 106; 18-39years) with idiopathic hypersomnia were recruited through national hypersomnia patient organizations.

Studies with genetically modified mice have implicated the transcriptional regulator STAT3 as a key modulator of bone development. STAT3-OKO knockout mouse lines were generated in two genetic backgrounds, pure C57BL/6 (STAT3-OKO-BL) and mixed C57BL/6, CD1 (STAT3-OKO-M). Both lines exhibited defective postnatal bone development resulting in reduced body weight and shortened femurs that displayed low bone mineral density as well as cortical widening and thinning in the diaphyseal region.

Unlabelled: Mediation analysis has emerged as a versatile tool for answering mechanistic questions in microbiome research because it provides a statistical framework for attributing treatment effects to alternative causal pathways. Using a series of linked regressions, this analysis quantifies how complementary data relate to one another and respond to treatments. Despite these advances, existing software's rigid assumptions often result in users viewing mediation analysis as a black box.

Contamination with exogenous DNA presents a significant challenge in ancient DNA (aDNA) studies of single organisms. Failure to address contamination from microbes, reagents, and present-day sources can impact the interpretation of results. Although field and laboratory protocols exist to limit contamination, there is still a need to accurately distinguish between endogenous and exogenous data computationally.

Early career teacher attrition disrupts school continuity, precludes many of those who leave from achieving expertise, and drains economic resources from school systems. In a longitudinal cluster randomized controlled trial (k = 8, n = 98), we examined the impact of a 9-week meditation-based intervention on undergraduate preservice teachers' rates of attrition from teaching approximately 4 years later. The odds of attrition among intervention group participants 3 years into their teaching careers were significantly reduced by at least 77.

Contingency management (CM) is notably successful as a substance use disorder treatment and is most effective when targeting monosubstance use. Evidence suggests the effects of CM exceed predictions based on the value of the incentives delivered for monosubstance abstinence. In this systematic review, we examine common variations of CM interventions applied to a single substance to determine what factors may contribute to the larger effect.

Objective: Mind-wandering is a pervasive human brain state and, when in excess, may promote negative affect and neuropsychiatric conditions. Mindfulness meditation may promote alternate brain states, improving affect and reducing stress. An understanding of the neural basis between these brain states could thus advance treatment of neuropsychiatric conditions, including those associated with epilepsy.

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
  • The risk of zoonotic diseases, which are diseases transmitted from animals to humans, is particularly high for individuals in close contact with both domestic and wild animals, especially in remote Arctic regions.
  • Approximately 75% of human infectious diseases are zoonotic, and the potential health impacts increase in areas with limited healthcare access and disease surveillance.
  • The Arctic is facing changes from pollution, climate change, and biodiversity loss, which heighten the risk of these diseases, necessitating a One Health approach that integrates human, animal, and environmental health to address these challenges effectively.

Flow synthesis is becoming increasingly relevant as a sustainable and safe alternative to traditional batch processes, as reaction conditions that are not usually achievable in batch chemistry can be exploited (for example, higher temperatures and pressures). Telescoped continuous reactions have the potential to reduce waste by decreasing the number of separate unit operations (e.g.

Objective: Recent theoretical work suggests that the expression of emotions may differ among Black and White Americans, such that Black Americans engage more frequently in expressive suppression to regulate emotions and avoid conflict. Prior work has linked expressive suppression usage with increases in cardiovascular disease risk, suggesting that racialized differences in expressive suppression usage may be one mechanism by which racism "gets under the skin" and creates health disparities.

Method: To examine racialized differences in expressive suppression and blood pressure (a measure of cardiovascular disease risk), we used self-report and facial electromyography (fEMG) data from two cohorts of Black and White Americans from the Midlife in the United States (MIDUS) longitudinal study (MIDUS 2, n = 271, 34.

The chiral iridium rotors Ir(ppy)(pyX)Cl (X = CC-SiR, R = alkyl) remarkably contain two distinct rotational conformers in the ground (S) and excited (T) states that can be detected by NMR and emission measurements respectively at variable temperatures. The observed phosphorescent emissions, vibronic (involving L = ppy) and broad (L = pyX), arise from different triplet ligand to metal charge transfers from the two rotational conformers at distinct MLCT excited states. Both conformers exist in these Ir(ppy)(pyX)Cl rotors due to the electron-withdrawing, conjugated substituent X.

Developmental axon pruning is controlled by a careful balance of pro- and anti-apoptotic signals, which are activated in response to external cues to sculpt mature neuronal circuitry. In this issue of , Abraham define a safeguard against apoptotic axon pruning and illustrate that Siah3 represses Parkin-mediated mitophagy to control the availability of axonal mitochondria that activate the pruning process.

PD-1 is a key negative regulator of CD8 T cell activation and is highly expressed by exhausted T cells in cancer and chronic viral infection. Although PD-1 blockade can improve viral and tumor control, physiological PD-1 expression prevents immunopathology and improves memory formation. The mechanisms driving high PD-1 expression in exhaustion are not well understood and could be critical to disentangling its beneficial and detrimental effects.
