The Effectiveness of Methylene Blue in Adult Shock: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Controlled Trials

David Rene Rodríguez-Lima · Adelaida Rodríguez-Villegas · Juan Diego Toro Egas · Esther María Campo Bautista

Background/Objectives: Methylene blue (MB) has re-emerged as an adjunctive vasopressor-sparing therapy in vasoplegic shock states, with emerging evidence supporting its hemodynamic benefits; however, its effect on mortality remains uncertain. We systematically evaluated the effectiveness of MB versus standard therapy i...

Processing and Applications of Photodetectors Based on Hybrid Halide Perovskites and Their Heterostructures

Maria J. Oyola‐Torres · Sergio Castrillon S. · David Steinberg · Lucia A. M. Saito · y 2 más

ABSTRACT Halide perovskites have become leading candidates for next‐generation photodetectors because of their tunable bandgaps, strong light absorption, high carrier mobility, and compatibility with versatile fabrication methods. As the field has advanced, processing has emerged as a central factor governing the morph...

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Nash E. Turley · Harold Pulido‐Guarín · Daniel Nossa‐Suárez · Gabriella Hoffmann · y 3 más

ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional traits. We studied bee communities at 14 sites across a 3000 m elevational gradient in the Colombian Andes. We measured morphological traits on all individuals (body size, relative leg length, relative wing len...

Human, technical and conceptual skills among Colombian managers: revisiting Katz’s model from a workplace learning perspective

Manuel Mendez-Pinzon · Nestor U. Salcedo · Adela Margarita Vélez Rolón · Maria González-Molina

Purpose This paper examines the relative importance and interrelationships of three managerial skill dimensions – human, technical and conceptual – among Colombian professionals participating in a managerial development program. Drawing on Katz’s typology, the purpose of this study is to discuss these competencies thro...

Bamboo as a Functional Gradient Biomaterial

Jose Israel Cardenas-Jimenez · Diógenes de Jesus Ramirez-Ramirez · Cristian David Correa-Álvarez

Bamboo as a functional gradient biomaterial refers to the understanding of bamboo culms as naturally hierarchical, anisotropic, and radially heterogeneous lignocellulosic structures whose mechanical, chemical, and conversion properties vary across the wall thickness. Gradients in fiber volume fraction, vascular bundle...

Se analizan las formas de producción y apropiación del espacio público (EP) recreo-deportivo en barrios populares de Manizales, Colombia, y el papel de las prácticas cotidianas en su construcción social. Se desarrolló un estudio comparativo de casos múltiples en la comuna Nuevo Horizonte, que incluyó tres unidades de a...

Recent strategies in synthetic food production for sustainable food security: applications and challenges

Pawan Kumar Kanaujia · Manikant Tripathi · Nagendra Kumar Rai · Rajat Pratap Singh · y 3 más

Due to rapid growth in population, instability in conventional agricultural production, and depletion of natural resources, currently, there is huge pressure to fulfill the demands for nutritious, safe, and cheaper food. Environmental changes have also impacted the livestock, forestry, aquaculture, and fisheries produc...

Hydrological modification drives century-scale eutrophication and invasion increasing invertebrate assemblage heterogeneity in Lake Fúquene, Colombia

Jorge Salgado Bonnet · Camila Jaramillo-Monroy · Maria Isabel Vélez · Yi Xi Kang · y 2 más

Abstract Hydrological alteration, eutrophication and macrophyte invasion generate novel ecological states and biotic homogenization in shallow lakes. As these stressors increasingly co-occur and unfold over decades to centuries, disentangling their combined effects on invertebrate assemblages remains however challengin...

Armed conflict as a socio-ecological disturbance: identifying priority ecological restoration scenarios using fuzzy logic in Colombia

Ana María Medina-Sánchez · Germán Leonardo Jiménez Romero · Francisco Villa-Rojas

Abstract The armed conflict in Colombia has historically functioned as a socio-ecological disturbance transforming land cover and degrading ecosystems. The ecological restoration (ER) of these territories represents an opportunity within the framework of the Peace Agreement but requires prioritization tools that incorp...
