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...

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...

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...

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...

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...

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...

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...

Empathy and Interpersonal Sensitivity in Pornography Use and Problematic Pornography Use: A Narrative Review

Abstract Purpose of Review Pornography consumption has become increasingly prevalent in digital environments, with a subset of individuals developing problematic pornography use (PPU). Despite growing research interest, limited attention has been given to the role of empathy and...

Anti-Holomorphic Involutions and Langlands Duality on the Moduli Space of Principal G2-Bundles

Let X be a compact Riemann surface of genus g≥2 equipped with an anti-holomorphic involution τ, and let M(G2) denote the moduli space of stable principal G2-bundles over X. We study the fixed-point loci M(G2)σ of the involutions σ=θ∗∘τ∗ on M(G2), where θ is a Cartan involution of...

Observational signatures of negative mass wormholes through their shadows

Abstract Systems containing objects with negative mass (NMOs) are considered. Such a system consists of one object with positive mass and one NMO, where a bound state exists even though the force exerted by the NMO on the object with positive-mass is repulsive. Unlike standard bi...
