Stabilizing milk-derived extracellular vesicles (mEVs) through lyophilization: a novel trehalose and tryptophan formulation for maintaining structure and Bioactivity during long-term storage.

Extracellular vesicles (EVs) are widely investigated for their implications in cell-cell signaling, immune modulation, disease pathogenesis, cancer, regenerative medicine, and as a potential drug delivery vector. However, maintaining integrity and bioactivity of EVs between Good Manufacturing Practice separation/filtration and end-user application remains a consistent bottleneck towards commercialization. Milk-derived extracellular vesicles (mEVs), separated from bovine milk, could provide a relatively low-cost, scalable platform for large-scale mEV production; however, the reliance on cold supply chain for storage remains a logistical and financial burden for biologics that are unstable at room temperature.

Genome-wide association study unravels mechanisms of brain glymphatic activity.

Brain glymphatic activity, as indicated by diffusion-tensor imaging analysis along the perivascular space (ALPS) index, is involved in developmental neuropsychiatric and neurodegenerative diseases, but its genetic architecture is poorly understood. Here, we identified 17 unique genome-wide significant loci and 161 candidate genes linked to the ALPS-indexes in a discovery sample of 31,021 individuals from the UK Biobank. Seven loci were replicated in two independent datasets.

Examining Discrimination as a Distal Moderator of the Proximal Association Between LGBQ+ College Students' Alcohol Use and Cyber Dating Abuse.

Comprehensive and inclusive dating abuse prevention is hindered by a lack of research on proximal antecedents of cyber dating abuse (CDA) among lesbian, gay, bi-/pansexual, queer, and other nonheterosexual (LGBQ+) young adults. Guided by sexual minority stress and alcohol-related violence theories, we addressed this gap by examining whether (a) alcohol use preceded and was positively related to CDA perpetration and (b) more frequent LGBQ+-based discrimination strengthened this association. LGBQ+ college students ( = 41; 75.

Enhancing representation of special populations: An approach to the inclusion of women veterans in VA clinical trials.

The under-recruitment of historically marginalized populations into clinical trials thwarts equitable inclusion of individuals who could benefit from healthcare innovations and limits the generalizability of results. For decades, the Veterans Health Administration (VA) has conducted large clinical trials that impact clinical guidelines for veterans and civilians alike. Within the VA, women are a numeric minority, and recruitment of this population into trials is challenged by gender-specific care structures, distinct demographic characteristics, and mistreatment such as higher rates of military sexual trauma and harassment on VA grounds.

Stormwater controls for channel stability: Focusing on bed material transport prevents degradation.

The hydrologic benefits of catchment-scale implementation of stormwater control measures (SCMs) in mitigating the adverse effects of urbanization are well established. Nevertheless, recent studies indicate that the Unified Stormwater Sizing Criteria (USSC) regulations, mandating the combined use of distributed and storage stormwater controls, do not protect channel stability, despite their effectiveness in reducing runoff from impervious surfaces. The USSC are the basis of SCM design in 11 U.

Impacts of climate change on storm event-based flow regime and channel stability of urban headwater streams.

Due to the recent improved availability of global and regional climate change (CC) models and associated data, the projected impact of CC on urban stormwater management is well documented. However, most studies are based on simplified design storm analysis and unit-area runoff models; evaluations of the long-term, continuous hydrologic response of extensive stormwater control measures (SCM) implementation under future CC scenarios are limited. Moreover, channel stability in response to CC is seldom evaluated due to the input data required to develop a long-term, continuous sediment transport model.

Interaction of breast cancer-relevant DNA repair genes and air pollution in relation to breast cancer risk in UK biobank.

We investigated if selected polymorphisms in DNA repair genes modify the association between exposure to particulate matter ≤ 10 micron in diameter (PM) and breast cancer (BCa) risk. We included 150,929 postmenopausal women (5,969 with BCa) from UK Biobank, a population-based prospective cohort. Cancer diagnoses were ascertained through the linkage to the UK National Health Service Central Registers.

Primary and middle school students' views on inclusive physical education: Perceptions, practices, and future directions.

Background: Physical Education (PE) classes are vital for nurturing students' social development and promoting collaboration. This study examined how primary and middle school students perceived PE classes, with a focus on collaboration, well-being and enjoyment, teacher behavior, the inclusion of nondisabled and disabled students, and general class behavior.

Methods: One-hundred and seventy students (24 primary school and 146 middle school students) were surveyed using a questionnaire.

From division to 'divergence': to understand wood growth across timescales, we need to (learn to) manipulate it.

Wood formation is the Rosetta stone of tree physiology: a traceable, integrated record of physiological and morphological status. It also produces a large and persistent annual sink for terrestrial carbon, motivating predictive understanding. Xylogenesis studies have greatly expanded our knowledge of the intra-annual controls on wood formation, while dendroecology has quantified the environmental drivers of multi-annual variability.

Relationships between adrenal insufficiency and cardiovascular outcomes in patients with congestive heart failure.

Background And Aims: Patients with adrenal insufficiency (AI) face elevated risks during various hospitalizations including cardiovascular related admissions. Despite this, limited data exist specifically regarding congestive heart failure (CHF) in the context of AI. This investigation leveraged a comprehensive national database to examine the association between AI and cardiovascular outcomes among patients admitted with CHF.

Epicardial Substrate Ablation in Symptomatic Brugada Syndrome Patients: An Updated Systematic Review and Single-arm Meta-analysis.

Background: Brugada syndrome (BrS) is a genetic heart disease that predisposes individuals to ventricular arrhythmias and sudden cardiac death. Although implantable cardioverter-defibrillators (ICDs) and quinidine are primary treatments, recurrent BrS-triggered ventricular arrhythmias can persist. In this setting, epicardial substrate ablation has emerged as a promising alternative for symptomatic patients.

Vermont's Universal School Meals Program: Challenging the Neoliberal Education Paradigm.

This article examines the recent implementation of Universal School Meals (USM) programs in several US states in the context of the increasing influence of neoliberalism in the public schooling system. By subverting a neoliberal paradigm, USM programs disrupt prevailing narratives of poverty and work to reclaim education's central place in the public sphere. A systems-thinking analysis of this issue reveals USM programs to be a powerful leverage point for change.
