Endothelial Redox Dysregulation in Pulmonary Arterial Hypertension: Compartmentalized Mechanisms and Therapeutic Implications

Pulmonary arterial hypertension (PAH) is a progressive pulmonary vasculopathy in which endothelial dysfunction drives increased pulmonary vascular resistance and arterial remodeling. Redox signaling is central to endothelial homeostasis, and its disruption in PAH reflects changes...

Developing a drug-level feedback adherence counseling intervention for young MSM in the U.S.

Background: Young men who have sex with men (MSM) in the U.S. have suboptimal adherence to oral tenofovir-based pre-exposure prophylaxis (PrEP), undermining HIV prevention goals. Drug-level feedback using urine point-of-care tenofovir assays has improved adherence in Eastern and...

Association of chronic kidney disease with major cardiovascular outcomes following lower extremity endovascular revascularization

OBJECTIVE: Chronic kidney disease (CKD) amplifies cardiovascular risk, yet its stage-specific influence on perioperative outcomes following endovascular lower extremity revascularization (LER) for peripheral artery disease (PAD) remains poorly characterized. METHODS: We conducted...

Transforming federal emergency management: a new agenda for Canada

Abstract Canada’s emergency governance model no longer aligns with a risk environment shaped by accelerating climate change and increasingly complex multi-hazard events. Recent federal/provincial/territorial strategies acknowledge these growing pressures but have not materially r...

Exploring Health Sciences Students' Knowledge of the Role of Occupational Therapy on Interprofessional Collaborative Teams

The first emancipation: the forgotten history of abolition in revolutionary France

Histories of abolition movements often prioritize triumphant struggles, where the formerly oppressed overcome their state of subjugation against their oppressors and regain their natural rights ind...

Ultrafast Dynamics of Competing Dimethyl Disulfide Photodissociation Pathways

Abstract Disulfide photochemistry impacts a wide range of chemical processes from biological UV photodamage to polymer self-healing and green photocatalysis. Despite this, the response of disulfide bonds to deep-UV light remains poorly understood. Dimethyl disulfide serves as a m...

Regime shifts in South Florida groundwater: distinguishing upstream recharge from coastal sea level influences (1997–2022)

Groundwater dynamics in South Florida play an important role in shaping the hydrologic balance of the region. This study investigated long-term trends in groundwater elevation, surface water stages, and their interactions across Water Conservation Areas 3A and 3B, Everglades Nati...

A unifying principle linking water uptake and nutrient delivery in trees with implications for soilless vascular delivery

Tree productivity, orchard sustainability and dryland reforestation are constrained simultaneously by water scarcity and nutrient losses. Here a unifying nutrient-water principle is developed for woody plants. The principle states that the minimum soil-derived flow compatible wit...

Characterizing the B-cell senescence signature in driving the disease phenotype in COPD/emphysema

Increased cellular senescence is a key mechanism underlying chronic inflammation and airway remodeling in chronic obstructive pulmonary disease (COPD). Yet, the cellular composition and molecular features of the senescent microenvironment in COPD remain poorly understood. To addr...

CDC AIDS Project 72: The Prostitute Study

In the early years of the AIDS epidemic, the occurrence and potential for heterosexual transmission of human immunodeficiency virus type 1 (HIV 1) in the United States were uncertain. To better understand infection among women and the possible role of prostitution in the emerging...

Associations between substance use by type and HIV viral suppression across multiple cohorts in the US

Substance use among people with HIV (PWH) represents an important obstacle to further reductions in HIV transmission. Using data from a diverse collection of five studies including people with HIV in care and those in community cohorts, we report results for analyses of the assoc...

Brain structure correlates of circulating endocannabinoids and related lipids in early adolescents

Abstract The endocannabinoid (eCB) system underlies many biological processes and is thought to be critical in adolescent brain development. However, the eCB system’s contributions to brain morphometry during adolescence remains understudied. Here we investigated cross-sectional...

“Hearing the Ovarian Cancer Whisper”: A Pipeline Program Introducing Medical Students to Gynecologic Oncology, Focusing on the Diagnosis and Management of Ovarian Cancer

Abstract Purpose Pipeline programs help medical students explore and define future career pathways. The “Hearing the Ovarian Cancer Whisper” (HOW) Dr. Robert C. Knapp Award was created to expose medical students to gynecologic oncology, with emphasis on recognizing, treating, and...

Resource‐Based Carrying Capacity Estimates for the Florida Manatee ( Trichechus manatus latirostris ) in a Subtropical Estuary

ABSTRACT Resource‐based carrying capacity can constrain abundance and population dynamics of large herbivores, including in aquatic ecosystems. Seagrass decline in the Indian River Lagoon (IRL) has raised concern that reduced forage availability may limit foraging opportunities f...

Social Comparison in the Glasshouse: Rousseau and the Digital Self

Contemporary social media platforms have transformed the pursuit of recognition into a continuously visible and publicly mediated process. Individuals increasingly encounter themselves through profiles, metrics, and the anticipated judgments of others, making questions of identit...

Integrating bioplastics into waste management: barriers and pathways to a circular economy

Bioplastics have emerged as promising alternatives to conventional fossil-based plastics because of their potential to reduce dependence on non-renewable resources and support the transition towards a circular economy. However, their environmental sustainability is determined not...

Engineering Metrics for Full-Scale Viability of PFAS Sorbent Regeneration

Abstract Evolving global regulations of per- and polyfluoroalkyl substances (PFASs) are driving rapid expansion of sorbent-based treatment in drinking water and industrial effluents. Granular activated carbon and anion-exchange resins remain among the best available technologies,...

Well-posedness of the focusing stochastic nonlinear Schrödinger equation: $$L^2$$-critical and supercritical cases

We study the focusing $$L^2$$ -critical and supercritical stochastic nonlinear Schrödinger equation subject to additive or multiplicative noise. We investigate global or long time behavior of solutions in $$H^1$$ , which would correspond to global well-posedness in the determinis...

Reporting Non-Consensual Intimate Imagery: An Audit Study of Deepfakes

Non-consensual intimate imagery (NCII) inflicts significant harm. Currently, victim-survivors can use two mechanisms to report NCII online—as a non-consensual nudity violation or as copyright infringement. We conducted an audit study of takedown speed of NCII reported to X (forme...
