Leiomyosarcoma of the Renal Vein That Enlarged Laterally While Preserving the Structure of the Renal Vein Lumen

ABSTRACT Introduction Primary renal vein leiomyosarcoma is an extremely rare disease and the tumor often infiltrates the vessel wall. We report a case of primary renal vein leiomyosarcoma that enlarged while preserving the structure of the renal vein lumen. Case Presentation A 64...

COPD/OSA phenotypes and inpatient outcome patterns among primary total hip arthroplasty hospitalizations: a national inpatient sample study, 2016–2022

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) are common among patients undergoing total hip arthroplasty (THA), but whether COPD-only, OSA-only, and coexisting COPD + OSA define distinct inpatient risk phenotypes remains unclear. This retrospecti...

Design of a Constructed Wetland as a Nature-Based Solution for the Japanese Garden Lagoon, La Paz, Bolivia

The Japanese Garden of La Paz, Bolivia, is a sociocultural space with high biodiversity, with its lagoon receiving treated effluent from the “Las Cholas” Wastewater Treatment Unit. Preliminary monitoring revealed elevated organic matter concentrations, raising concerns about wate...

Effects of vaginal structure and active contractile force on the spatiotemporal evolution of pelvic organ prolapse

Pelvic organ prolapse (POP) significantly impairs women’s quality of life and imposes substantial health and economic burdens. Although finite element (FE) biomechanics have been widely used to study POP, existing models have critical limitations: they simplify the vagina as isol...

Unhappy Regions and Cities? Urban Agglomeration and Individual Happiness in Spain

ABSTRACT This paper examines how individual subjective well‐being varies across space in Spain, with a particular focus on the roles of city size and long‐term population growth. Using individual‐level data from multiple waves of the Spanish Centre for Sociological Research surve...

Fe-Coordinated Dopamine Derivative-Based Flame Retardant Epoxy Resin: Thermal Stability, Flame Retardancy, and Mechanism

Abstract With the increasing fire safety requirements of epoxy resin (EP), developing sustainable and efficient flame retardants has become highly desirable. In this work, a bio-based phosphorus–nitrogen flame retardant (DA-HCCP) was synthesized using dopamine (DA) and hexachloro...

Sequential–hierarchical coordination for multi-task enroute air traffic control

Enroute air traffic controllers (ATCOs) face two fundamentally distinct yet interrelated operational tasks: macroscopic flow-level planning and flight level assignment for sector-wide traffic optimization over time horizons on the order of tens of minutes and microscopic real-tim...

Protocol for isolation and cryopreservation of human peripheral blood mononuclear cells for high-resolution respirometry

High-resolution respirometry (HRR) of peripheral blood mononuclear cells (PBMCs) relies on controlled preanalytical procedures. Here, we present an optimized workflow for PBMC isolation from human whole blood, followed by short-term cryopreservation at −80°C. The protocol include...

Inflation-Adjusted Medicare Reimbursement for Common Dermatologic Procedures

This cross-sectional study examines inflation-adjusted reimbursement for 46 common dermatologic procedures from 2007 to 2026, focusing particularly on the 2021-2026 interval.

Identifying the Role of Developing Countries in the United Nations: Case Studies of India and Vietnam

This article focuses on India and Vietnam’s participation in the United Nations (UN) as an example of a multilateral approach to assert influence in global governance. It highlights India’s role as the representative voice for developing countries in the Global South, asserting i...

Retail café cup preferences: evidence from global and domestic coffee brands

Purpose The rapidly expanding coffee market in an emerging economy provides the context for this study, which examines how café cup design in café retailing influences purchase intention. It compares customers of Starbucks (a global semi-luxury brand) and Luckin Coffee (a domesti...

Thermodynamic and economic comparison of pressure shift freezing and isochoric pressurization without a hyperbaric pump

Abstract Pressure-assisted freezing produces frozen foods with finer ice crystals, less drip loss and longer microbiological shelf life than conventional freezing, but its adoption has been limited because the conventional implementation, pressure-shift freezing (PSF), requires a...

Why draw lots? Funder motivations for using partial randomisation to allocate research grants.

Background The strengths and weaknesses of peer review in grant allocation continue to be a hot topic, especially with the rise of agentic AI in the formulation of grant applications. Expert judgement is at the heart of research funding processes. However, interventions which mil...

Electrophoretic Deposition of Additive-Free Zeolitic Imidazolate Framework-67-Derived Cobalt Oxide Anodes for Lithium-Ion Batteries

Additive-free electrode architectures are important for clarifying the intrinsic lithium-storage behavior of MOF-derived conversion-type anode materials, because conventional slurry electrodes contain polymer binders and conductive carbon additives that can obscure the electroche...

Climate Change and Healthcare System Resilience: Stakeholder Perspectives on Mitigating Climate-Related Health Impacts in Low-Resource Settings

Climate change increasingly threatens human health and healthcare system effectiveness by intensifying existing vulnerabilities and pressures. In sub-Saharan Africa, Nigeria is particularly vulnerable to climate-related hazards, including food insecurity, extreme weather events a...

Orthoptera assemblages in subtropical paddy fields: role, effect of plant phenology, and cultivation area

Abstract Irrigated rice crops are considered artificial wetlands, with high productivity and biodiversity, especially in insect populations such as orthopterans. Although these predominantly herbivorous insects include several species of agricultural concern, their occurrence and...

Feedback engagement strategies and metrics for consumers in vulnerable circumstances: An empty rapid review and recommendations for further research

Across sectors, there is an increasing recognition of the need to identify and support consumers in vulnerable situations. To assess whether existing support measures are effective and how they might be improved, satisfaction surveys are commonly used. However, low response rates...

From Limb Salvage to Function

Mangled extremities resulting from high-energy trauma have long been one of the most formidable challenges in orthopedic trauma and microsurgery. Historically, treatment success was measured by anatomic limb survival. However, clinical practice has demonstrated that a nonfunction...
