Cytosolic aggregation of the nuclear protein TDP-43 is associated with many neurodegenerative diseases, but the triggers for TDP-43 aggregation are still debated. Here, we demonstrate that TDP-43 aggregation requires a double event. One is up-concentration in stress granules beyond a threshold, and the other is oxidative stress. These two events collectively induce intra-condensate demixing, giving rise to a dynamic TDP-43 enriched phase within stress granules, which subsequently transitions into pathological aggregates...

BACKGROUND: A third of people with epilepsy are drug resistant. People with drug-resistant epilepsy (DRE) have a higher risk of mortality and physical injuries than those who respond to anti-seizure medication (ASM). This study describes patient characteristics, comorbidities, and mortality in people with DRE in the UK. METHODS: The Clinical Practice Research Datalink was utilised to select people with DRE prescribed a third ASM between 1 January 2011 and 31 March 2021...

BACKGROUND: Youth who experience traumatic events are at a substantially higher risk of engaging in substance use and sexual risk behaviors and problems (eg, HIV acquisition) than their non-trauma-exposed counterparts. Evidence-based substance use and risky sexual behavior prevention may reduce the risk of these outcomes. Trauma-focused mental health treatment provides a window of opportunity for the implementation of such preventive work with these youth. However, overburdened clinicians face challenges in adding prevention content while implementing evidence-based treatments...

With populations of threatened and endangered species declining worldwide, efforts are being made to generate high quality genomic records of these species before they are lost forever. Here, we demonstrate that data from single Oxford Nanopore Technologies (ONT) MinION flow cells can, even in the absence of highly accurate short DNA-read polishing, produce high quality de novo plant genome assemblies adequate for downstream analyses, such as synteny and ploidy evaluations, paleodemographic analyses, and phylogenomics...

Interleukin-10 mediates regulatory functions of commensal-specific TH17 cells in murine small intestine.

The enzyme α-amylase has long been a commonly targeted protein in serological tests for saliva. While being especially abundant in saliva, α-amylase is detectable in vaginal secretions, sweat, fecal matter, breast milk and other matrices. As a result, assays for α-amylase only provide a presumptive indication of saliva. The availability of mass spectrometry-based tools for the detection of less abundant, but more specific, protein targets (e.g., human statherin) has enabled the development of high confidence assays for human saliva...

The activity of β-ureidopropionase, which catalyses the last step in the degradation of uracil, thymine, and analogous antimetabolites, is cooperatively regulated by the substrate and product of the reaction. This involves shifts in the equilibrium of the oligomeric states of the enzyme, but how these are achieved and result in changes in enzyme catalytic competence has yet to be determined. Here, the regulation of human β-ureidopropionase was further explored via site-directed mutagenesis, inhibition studies, and cryo-electron microscopy...

Shear-thinning hydrogels represent an important class of injectable soft materials that are often used in a wide range of biomedical applications. Typically, the hydrogel network is formed prior to injection and "heals" once the shearing forces have been removed. However, creation of new shear-thinning materials often requires that factors such as viscosity, injection rate/force, and needle gauge be evaluated to achieve efficient delivery, while simultaneously protecting potentially sensitive cargo (e.g., cells)...

This study aimed to better understand the relationship between bone-related biomarkers and nutrient stress in the context of metabolic health. We investigated plasma osteocalcin (OC) during an oral glucose challenge and experimental hyperinsulinemia in Type 2 diabetes (T2DM) and lean healthy controls (LHC). Older individuals with obesity and T2DM (n = 9) and young LHCs (n = 9) underwent a 75g oral glucose tolerance test (OGTT) and a 40 mU/m2 /min hyperinsulinemic-euglycemic clamp. Plasma undercarboxylated OC (ucOC) and total OC were measured at baseline, 60mins, and 120mins of the OGTT and clamp via ELISA...

The serious impact of the Covid-19 pandemic underscores the need for rapid, reliable, and high-throughput diagnosis methods for infection. Current analytical methods, either point-of-care or centralized detection, are not able to satisfy the requirements of patient-friendly testing, high demand, and reliability of results. Here, we propose a two-point separation on-demand diagnostic strategy that uses laser desorption/ionization time-of-flight mass spectrometry (LDI-TOF MS) and adopts a stable yet cleavable ionic probe as a mass reporter...

BACKGROUND: X-linked myotubular myopathy (XLMTM) is a rare, life-threatening congenital muscle disease caused by mutations in the MTM1 gene that result in profound muscle weakness, significant respiratory insufficiency, and high infant mortality. There is no approved disease-modifying therapy for XLMTM. Resamirigene bilparvovec (AT132; rAAV8-Des-hMTM1) is an investigational adeno-associated virus (AAV8)-mediated gene replacement therapy designed to deliver MTM1 to skeletal muscle cells and achieve long-term correction of XLMTM-related muscle pathology...

PURPOSE OF REVIEW: This systematic review aims to inform the current state of evidence about the efficacy and effectiveness of medical cannabis use for the treatment of LBP, specifically on pain levels and overall opioid use for LBP. Searches were conducted in MEDLINE (PubMed), Embase, and CINAHL. The search was limited to the past 10 years (2011-2021). Study inclusion was determined by the critical appraisal process using the Joanna Briggs Institute framework. Only English language articles were included...

OBJECTIVE: To compare mental health indicators among undergraduates in Fall 2019, before the COVID-19 pandemic, and Fall 2020, when many students returned to campus amidst restrictions on in-person contact. PARTICIPANTS: Analyses included 26,881 undergraduate students, aged 18-24, from 70 U.S. institutions. METHODS: Students completed the National College Health Assessment-III survey in Fall 2019 or Fall 2020. RESULTS: The prevalences of high stress, loneliness, a low flourishing score, and serious psychological distress increased in 2020 compared to 2019...

PURPOSE: This report describes a multifaceted, trauma-informed initiative developed to address racial/ethnic maternal and infant health inequities in Washington, D.C. DESCRIPTION: Structural racism and systemic oppression of marginalized communities have played a critical role in maternal and infant health inequities in the United States. Black birthing individuals are exponentially more likely to experience adverse birth outcomes, including preterm birth, low birth weight and maternal mortality...

We examined the predictive utility of the Behavior Assessment System for Children-2 Behavioral and Emotional Screening System (BASC-2-BESS) and Strengths and Difficulties Questionnaire (SDQ) in identifying students with a mental disorder. Data were collected in a two-stage study over 34 months with kindergarten-12th grade (K-12) students (aged 5-19 years) in four U.S. school districts. In Stage 1, teachers completed the BASC-2-BESS and the SDQ. In Stage 2, parents of 1,054 children completed a structured diagnostic interview to determine presence of a mental disorder...

Decades of research have indicated that reading self-concept is an important predictor of reading achievement. During this period, the population of emergent bilinguals has continued to increase within United States' schools. However, the existing literature has tended to examine native English speakers' and emergent bilinguals' reading self-concept in the aggregate, thereby potentially obfuscating the unique pathways through which reading self-concept predicts reading achievement. Furthermore, due to the overreliance of native English speakers in samples relating to theory development, researchers attempting to examine predictors of reading achievement may a priori select variables that are more aligned with native English speakers' experiences...

Preparation for bias messages (PFB), represent a specific form of racial socialization, used to inform youth about racism and how to cope with racism-related adversity. Although research commonly examines how frequently PFB are delivered to children, few studies have qualitatively explored the heterogeneity in the content of such messages, making it difficult to ascertain how caregivers prepare and coach their children to negotiate incidents of racism-related violence. To address this gap in the literature, the present study qualitatively examined the content of PFB given to Black children from their mothers following high-profile incidents of anti-Black violence...

BACKGROUND: Substance use, sexual assault, and sexual risk behaviors are common among adolescents and are interrelated. Nearly 1 in 5 adolescents use substances before sexual encounters, placing these young people at risk for both sexual assault and sexual risk behaviors. Primary care visits present a unique opportunity to address multiple health risk behaviors. OBJECTIVE: Teen Well Check is a web-based integrated prevention program for substance use, sexual assault, and sexual risk behaviors with demonstrated usability and acceptability among patients and providers...

This study sought to describe the impact of the COVID-19 pandemic on community pharmacy practice and its workforce. Interviews were conducted with 18 key informants from pharmacy associations and community pharmacists representing chain and independent pharmacy organizations across the United States from January to May 2022. Interview notes were analyzed using a rapid content analysis approach. Four themes resulted: (a) patient care at community pharmacies focused on fulfilling COVID-19 response needs; (b) pharmacists' history as immunizers and scope of practice expansions facilitated COVID-19 response efforts; (c) workforce supply shortages impeded COVID-19 response efforts and contributed to burnout; and (d) maintaining community pharmacy workforce's readiness will be critical to future emergency preparedness and response efforts...
