Effects of electrical stimulation on the cardiogenic differentiation of mesenchymal stem cells: A systematic review

Electrical stimulation has emerged as a promising strategy for promoting cardiogenic differentiation of mesenchymal stem cells; however, the available evidence remains highly heterogeneous across stimulation parameters, experimental platforms, and outcome measures. This systemati...

Rural occupational health in Colombia: policy–practice gaps among agricultural workers in Bolívar, Valle del Cauca

This study examines policy–practice gaps in occupational safety and health (OSH) protection among agricultural workers in Bolívar, Valle del Cauca, Colombia. A multi-method design combined 14 semi-structured interviews and two focus groups with an adapted ILO Vision Zero Fund sur...

Photocatalytic Performance of TiO2-Based Nanomaterials for Water Remediation

Photocatalytic water treatment using titanium dioxide (TiO2)-based nanomaterials has emerged as a promising green technology for removing organic and inorganic contaminants. However, the translation of laboratory-scale photocatalysts into industrial applications remains limited b...

Valorization of Mopa Mopa Resin as a Renewable Bio-Based Adhesion Promoter for Sustainable Wood Adhesives

The search for renewable raw materials for developing wood adhesives has driven the study of natural resins with intrinsic adhesive properties. This work evaluated Mopa Mopa resin (Elaeagia pastoensis Mora) as an adhesion promoter in formulations for wood-to-wood bonding of pine....

Stochastic Convex Optimization for Day-Ahead Shared Battery Storage Scheduling in Solar Energy Communities

Energy communities represent a transformative paradigm for decentralized renewable energy integration, enabling collective investment in photovoltaic (PV) systems and battery energy storage systems (BESS) to achieve economic and environmental benefits. However, the optimal operat...

What explains the implementation gap in foresight-designed policies? Evidence from a regional development strategy in Chile

Abstract Foresight and strategic planning have been widely recommended in public policy design to reduce uncertainty and improve governance. However, the gap between a foresight-designed public policy and its effective implementation remains a critical challenge for long-term gov...

The first annotated checklist of the bees of Colombia reveals an overlooked diversity and areas with major data deficiencies

Background Most existing knowledge about bee biodiversity comes from temperate regions, where diversity is presumed highest—yet substantial data gaps across the tropics confound this pattern. Checklists are critical for documenting species presence, identifying knowledge gaps, an...

The Influence of Psychological and Social Variables on Entrepreneurial Intention

This study aimed to evaluate the influence of attitude, subjective norms, and perceived behavioural control based on the Theory of Planned Behaviour (TPB), entrepreneurship education, and entrepreneurial self-efficacy on entrepreneurial intention in Santander, Colombia. This rese...

Human Spokesperson Versus Artificial Intelligence Avatar and Authorship Disclosure in Digital Advertising: Effects on Performance Metrics

Virtual influencers generated by artificial intelligence have emerged as a strategic tool in digital advertising, although evidence regarding their actual effectiveness in market campaigns remains limited to laboratory experiments based on self-report measures. This study examine...

Antiproteinuric Response to Finerenone in Diabetic Kidney Disease: Responder and Non-Responder Subgroup Analysis of the FINDKDLATAM Study

Background/Objectives: Albuminuria is an early marker of kidney damage and an independent predictor of adverse outcomes, making its reduction a key therapeutic goal. Finerenone, a selective nonsteroidal mineralocorticoid receptor antagonist, has demonstrated renal and cardiovascu...

Ileocecal Paracoccidioidomycosis Presenting as a Pseudotumoral Lesion in a Pediatric Patient: A Histopathological Diagnostic Challenge

Ileocecal pseudotumoral lesions in pediatric patients pose a significant diagnostic challenge, particularly in endemic regions where infectious and neoplastic conditions overlap. Gastrointestinal paracoccidioidomycosis (PCM) is rare and may closely mimic intestinal tuberculosis o...

Optimal electric vehicle charging station planning in distribution networks using a Pareto-based parallel multi-verse optimizer

This study develops a Pareto-based framework for optimal electric vehicle charging station (EVCS) planning in distribution networks under time-varying conditions. EVCS locations and integer EV allocations are jointly optimized to minimize weekly technical energy losses and maximi...

Determinants of the Adoption of Generative Artificial Intelligence in Academic Research: A Structural Equation Model from Colombian Universities

This study examined the determinants of both the intention to use and the self-reported use of generative artificial intelligence (GAI) in academic research by means of a partial least squares structural equation model (PLS-SEM), collecting data from 167 research-active faculty m...

Comparing Machine and Deep Learning for Electricity Theft Detection from Monthly Billing Data in an Emerging Energy Market

This study addresses a regime-conditioned question in electricity theft detection: when only monthly billing series and inspection-confirmed labels are available, which supervised model families recover irregular consumption without relying on the temporal resolution of advanced...

Digital Engagement in Geopolitical Crises: A Comparative Analysis of Message Attributes on Instagram and X During the Capture of Nicolás Maduro

This study examines the determinants of digital engagement during geopolitical crises, using the capture of Venezuelan President Nicolás Maduro by U.S. forces on 3 January 2026 as a case study. The aim is to identify which message attributes drive audience interaction and how the...

Maternal and neonatal outcomes associated with expanded antibiotic therapy in preterm prelabor rupture of membranes

OBJECTIVE: To compare maternal and neonatal outcomes in women with preterm prelabor rupture of membranes (PPROM) managed expectantly with either ampicillin-erythromycin or an institutional alternative regimen combining ampicillin, ceftriaxone, and clarithromycin. METHODS: weeks (...

Resilient Seas: Environmental Drivers of Larval Fish Assemblages in the Gulf of Tortugas, Colombian Pacific

Nursery habitats sustain fish populations by supporting early life stages and buffering environmental variability, yet their functioning under climate oscillations remains poorly understood in the Eastern Tropical Pacific. We analyzed ichthyoplankton assemblages in the Gulf of To...

An Alternative Approach to 1 − γ and Riemann ζ Function

Although the relationship ( $\sum_{k=2}^\infty \frac{\zeta(k) - 1}{k} = 1 - \gamma$ ) between the harmonic series, the logarithmic function, and the Riemann Zeta function is known, explicit elementary derivations are scarce in the literature. A novel derivation of this relationsh...

Artificial Intelligence-Assisted Systematic Literature Reviews in Metabolic Phenotyping: A Methodological Framework and Validation Study

Abstract Systematic literature reviews are widely acknowledged to be at the top of most evidence hierarchies but are very time-consuming and labour-intensive. The advent of artificial intelligence (AI) offers possibilities to accelerate the review process. We propose a systematic...
