Baseline Ferritin and Body Composition as Correlates of Longitudinal Metabolic Changes During an Energy-Restricted Mediterranean-Style Intervention Across Three Overweight Phlogistic-Related Clinical Conditions

Background/Objectives: Chronic inflammation accompanies obesity, but correlations of longitudinal changes during dietary follow-up remain unclear. We described inflammatory profiles and examined associations of baseline ferritin and body composition with changes during a 32-week...

Spatial Variability and Magnitude of Soil Erosion in Vineyards Across Spain: Insights from Standardized ISUM Measurements

Soil erosion and sediment redistribution in vineyards often exceed tolerable thresholds, but comparative field measurements across regions remain limited because studies use different methods and sampling designs. This study assesses soil redistribution in vineyards using a commo...

Towards a creative, interdisciplinary, ecological and digital music education: The role of the soundscape in primary school curriculum in Latin America

Abstract This study examines the presence and representation of the concept of soundscapes in Latin American primary school music education curricula. A documentary analysis of 18 countries’ curricula is carried out, focusing on references to soundscapes and their derivatives. Th...

Lignans as a Potential Metabolomic Biomarker for Nut Consumption and EAT-Lancet Diet Score Adherence

Abstract Metabolomic biomarkers may represent reliable objective measurements and can be useful for assessing dietary intake and avoiding biases. The objective of this study is to identify novel metabolomic indicators of dietary patterns. Dietary, anthropometric, blood biomarkers...

Acceptance of the possibility of simulated patient death among final-year medical students: a repeated cross-sectional study across eight consecutive cohorts

Simulation scenario design has long been guided by a recommendation that the simulated patient should not be allowed to die, on the grounds that a fatal outcome may impair learning and compromise psychological safety. This "no-death paradigm" rests largely on expert opinion and o...

Phenolic Transfer and Dissolved-Oxygen Dynamics in Different White Wines Treated with Two Quercus alba Wood Samples with Contrasting Grain Widths

American oak is widely used in enology, but its interactions with white wine and the role of wood properties remain poorly understood. In this study, oxygen dynamics and changes in the phenolic composition of wines made from the Verdejo, Albillo, Rufete, and Puesta en Cruz variet...

A Qualitative Study of Barcelona Food Tours: Representing Gastronomic Heritage Through Urban Culinary Imaginaries

Gastronomy has acquired a central role in contemporary tourism where experiences centered around food are increasingly developed. Food tours have become a prominent urban tourism product due to their ability to connect tourists with local communities. These tours promote the expl...

Dust radiative effects and impact on energy production over the Mediterranean Basin

Abstract. Atmospheric aerosols are among the key factors affecting the Earth’s radiation budget, playing a fundamental role in understanding climate forcing, feedback mechanisms, and their impact on future climate projections and on solar energy systems. More specifically, dust a...

The role of density distribution in dynamics around irregular asteroids

Abstract In recent years, asteroids have become increasingly important targets in space exploration. In this work, we study the effects of variable internal density on orbital dynamics around asteroids using a synthetic model consisting of a straight segment with a variable densi...

Robot-assisted brain-computer interface therapy for post-stroke rehabilitation: Preliminary effects on motor, cognitive, and functional outcomes

Stroke is a leading cause of long-term disability, and severe upper-limb paresis often persists despite conventional rehabilitation. Brain–computer interfaces (BCIs) have been proposed to support motor recovery by pairing motor imagery with contingent sensory feedback, although c...

Machine Learning-Based Assessment of Land-Use Change, Forest Recovery, and Landscape Connectivity in Islamabad

LULCC is a major driver of habitat fragmentation, biodiversity loss, and declining landscape connectivity, particularly in rapidly urbanizing regions. Although Islamabad has experienced substantial urban expansion and forest-cover change, long-term city-scale assessments linking...

Hints of self-medication? Pathogen exposure-dependent foraging decisions of bumblebees

Abstract Self-medication is the selective consumption of compounds that reduce infection and is a widespread form of adaptive plasticity across animals. However, relevant medicinal floral compounds remain poorly tested in bees. Here, we used robotic flowers to test the hypothesis...

Learning Values Through Stories: The Impact of Narrative-Based Activities on Social and Civic Development in Early Childhood Education

Abstract The pedagogical efficacy of children’s stories within the classroom is fundamentally contingent upon critical teacher mediation, thereby transcending the traditional perspective that may regard them merely as a source of entertainment. The primary objective of this resea...

Language and usage patterns on Twitch: a gender-sensitive study of viewers and streamers

Abstract Purpose This study examines gendered communication and interactional dynamics on Twitch as a platform-mediated environment, analyzing usage practices and linguistic patterns among Spanish university student viewers and exploring the experiences of female video game strea...

Incidence, Causes, and Outcomes of Conversion to Open Surgery During Minimally Invasive Left Pancreatectomy: A Prospective Multicenter Study

ABSTRACT Background Minimally invasive left pancreatectomy (MILP) has become the preferred approach to treat lesions of the pancreatic body and tail. However, the procedure may require conversion to open surgery, with reported conversion rates varying widely in the literature. Th...

Incidence, prevalence, and ketoacidosis at onset of type 1 diabetes in Spain: a systematic review and critical assessment of the available evidence

The incidence, prevalence and onset of type 1 diabetes (T1D) with diabetic ketoacidosis (DKA) in Spain remain insufficiently characterized, despite multiple regional analyses. This study aims to summarize and critically assess epidemiologic data in Spain, incorporating insights f...

Analysis of the Prices and Opportunity Costs of Carbon Capture Projects in Mangroves Compared to Those in Other Productive Systems

Mangroves are highly productive ecosystems due to their great capacity to store carbon, but they are also vulnerable to human activities and adverse environmental conditions. Their conservation is often constrained by the opportunity costs of shifting from traditional economic ac...

Sustainable Extraction of Tagetes erecta L.: Comparative Metabolomics and Antifungal Activity against Grapevine Pathogens

Abstract The spread of fungicide-resistant pathogens has increased interest in plant-based antifungal agents for agricultural applications. We compared subcritical CO2 extraction (SbFE), ultrasound-assisted extraction (UAE), hot reflux extraction (HRE), and Soxhlet extraction (SE...

Continuous lactate-driven biohydrogen production from the organic fraction of municipal solid waste

The organic fraction of municipal solid waste (OFMSW) is a promising feedstock for biohydrogen production via dark fermentation. Lactate-driven dark fermentation (LD-DF) mitigates the impact of lactic acid bacteria (LAB) overgrowth, yet its application under continuous operation...

Host-ControlledStepwise CO2 Growth onMaleic Anhydride Revealed by Rotational Spectroscopy

Abstract Gas-phase aggregation of CO2 with organic compounds provides molecular-level benchmarks for understanding how weak interactions guide early cluster growth─a process relevant to CO2 recognition, uptake, and organization in chemically diverse environments. Here, clusters o...
