PurposeCombination treatments—thermal ablation (TA) and transarterial chemoembolisation (TACE) have been suggested for hepatocellular carcinoma (HCC). After TA a transient hyperemic zone appears around the ablated area, a potential target for TACE. The aim was to determine when this peri-ablational hyperemia is at its widest and most intensely perfused.Materials and methodsThis prospective study e

STUDY QUESTIONAmong women pregnant after IVF/ICSI, do obstetric outcomes differ for women diagnosed with endometriosis and/or adenomyosis according to definitions by International Deep Endometriosis (IDEA) and the revised Morphological Uterus Sonographic Assessment (MUSA) groups, compared to women without the disease?SUMMARY ANSWERWomen with endometriosis and/or adenomyosis have a higher risk of p

Background/Objectives: Empowered mothers are more likely to adopt recommended childcare practices, thereby contributing to reduced childhood undernutrition. However, the magnitude of the association between maternal empowerment and childhood undernutrition in Bangladesh has not been comprehensively assessed. This study aims to address this research gap. Methods: The Bangladesh Demographic and Heal

Affärsrättsligt Centrum vid Lunds universitet (ACLU) bedriver forsknings- och seminarieverksamhet på centrala förmögenhetsrättsliga områden. En viktig del av den verksamhet som bedrivs inom ACLU är att regelbundet publicera böcker med originalbidrag från forskare och praktiker som har anknytning till ACLU. Målsättningen för ACLU:s publikationer är att de ska belysa aktuella och praktiskt relevanta

Catalytic oxidation of ammonia (NH₃) is the key reaction in the Ostwald process for industrial nitric acid production. The reaction yields three nitrogen-containing products, N₂, N₂O, and NO, and the selectivity between them depends on the catalyst and the operating conditions. Most of what is known comes from steady-state studies on platinum and rhodium. This thesis studies what happens when the

Objective. High-frequency oscillations (HFOs) are a potential biomarker of the epileptogenic zone (EZ) in patients with focal epilepsy. Previous research has estimated that HFOs arise from regions as small as a single cortical column (1 mm3), making events difficult to detect with the coarse spatial sampling of clinical-standard electrocorticographic (ECoG) arrays. We tested whether high-resolutio

Understanding migration strategies in closely related species is essential to assess population-specific threats and to identify the ecological drivers of speciation. To compare migration strategies and environmental conditions across the annual cycle, we tracked Western Black-eared Wheatears, Eastern Black-eared Wheatears and Pied Wheatears. Individual migration routes were reconstructed from mul

Ecological constraints and changing societal values require businesses to reconsider innovation opportunities. Sufficiency constitutes an emerging sustainability strategy for businesses that focuses on the absolute reduction of inputs and consumption levels to restrict resource use. This particularly challenges aspects of value generation, strategic orientation, and consumer focus in the context o

Formulating Research Problems addresses one of the most critical yet often overlooked aspects of research: how to define and frame the problem at the heart of a study. While most research methods texts devote only a few pages to this question, Johan Alvehus offers a dedicated, accessible, and practical guide that helps students move beyond vague topics toward the development of clear, rigorous, an

Challengers struggle against more powerful elites and authorities to resolve environmental problems driven by social forces, but can sustainability research contribute to such collective action while remaining scientific? After five years of movement-relevant sustainability research using Burawoy’s extended case method, I seek to make three contributions. Empirically, I present strategic alliances

Background: Win statistics offer an alternative approach to clinical trials that use survival analysis to analyze composite endpoints. Our objective was to re-analyze data from previously published registry-based randomized controlled trials that produced hazard ratios using win statistics to evaluate the correspondence between them. Good correspondence was defined as both results being positive,

Hummeln is a simple impact structure located in south-eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln-1 with a focus on impact metamorphism and the impact process. We find that the drilling has penetrated a complex sedimentary successio

The dominant narrative on equity, diversity, and inclusion in U.S. medical research emphasises the underrepresentation of Black and Hispanic participants in clinical trials, largely based on therapeutic phase 2 and 3 trials. Far less attention has been paid to phase 1 trials—particularly those involving healthy volunteers who assume health risks without therapeutic benefit, often for money. Focusi

Glycobiology has undergone a profound conceptual transformation from a largely descriptive discipline to a central framework for understanding biological regulation in health and disease [...].

Polycyclic aromatic hydrocarbons (PAHs) of molecular mass (MM) 302 Da comprise numerous structural isomers that are of high concern for human health. Because of their multiplicity, low abundance in the environment, and limited availability of authentic standards, their occurrence, composition, and environmental health risk remain not well characterized. Here we extend the characterization of MM 30

Wetlands are often constructed to counteract eutrophication or brownification of downstream waters, although our understanding of their differences in efficiency and effects is still scarce. Therefore, we here used the upper and lower 95% confidence limits of the average retention capacity of 11 wetlands to represent efficient and inefficient wetlands, respectively. We then modelled future scenari

A random planar quadrangulation process is introduced as an approximation for certain cellular automata in terms of random growth of lines, called rays, from a given set of points. This model turns out to be a particular (rectangular) case of the well-known Gilbert tessellation, which originally models the growth of needle-shaped crystals from the initial random points with a Poisson distribution

Retrospective, propensity-score-adjusted (PSA) studies have indicated to practitioners in the field that contrast-induced acute kidney injury (AKI) after contrast-enhanced CT (CECT) is of minor importance or even non-existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant or even refusing CECT in risky patients. A critical revi

Process-based biosphere models, which formulate biophysical ecosystem processes, provide a mechanistic framework for understanding terrestrial carbon dynamics. In contrast, data-driven approaches, e.g., upscaling eddy covariance (EC) fluxes using satellite observations and machine learning, offer empirical estimates. These complementary methods often diverge significantly, particularly in estimati
