Ivan Cherrez-Ojeda · Thomas Rott · Karla Robles-Velasco · Ileana María Madrigal Beas · y 17 más

Abstract Background Hereditary angioedema (HAE) is a rare disease characterized by recurrent swelling episodes that may affect sleep and quality of life. Because data on sleep disorders in Latin American patients with HAE are limited, we assessed their prevalence and clinical correlates using structured sleep and HAE p...

Enthesis interdigitation: strength measures under FFT homogenisation

Villegas Bermudez, Diego Fernando · ROMERO SUAREZ, GERMAN ORLANDO

Deep learning based architecture for the correction of artifacts in magnetic resonance imaging MRI

Ríos Pérez, Jesús David

Los artefactos periódicos, como ringing, herringbone y zipper, reducen la calidad visual y cuantitativa de las imágenes de resonancia magnética cerebral, afectando la interpretación anatómica y el análisis posterior de las imágenes. Además, la disponibilidad limitada de conjuntos de datos pareados con imágenes libres d...

A Risk-Based Framework to Optimize Microbiological Testing of Primary Packaging Materials

Prada-Ramírez Harold Alexis · Cely-Veloza Willy · Ericsson Coy-Barrera · Humberto Zardo · y 5 más

Abstract Background Risk-based approaches are increasingly encouraged to optimize microbiological control strategies for non-sterile pharmaceutical materials. Primary packaging materials represent a critical interface, yet routine microbiological testing is often applied uniformly without considering material character...

Cortisol salival como biomarcador de estrés en adultos: revisión narrativa

María Alexandra Cely-Pedraza · Gisella Milagro Gutiérrez-Tobías · Xaviera Ivanna Aceros-Vega · Nadia Catalina Alfonso-Vargas

El cortisol es una hormona glucocorticoide cuya producción depende de la activación del eje hipotálamo-hipofisario-adrenal y cuya presencia en la saliva aumenta en situaciones de estrés. Su medición se ha posicionado como una alternativa no invasiva para analizar el estrés en adultos, dado que sus concentraciones guard...

Acetaminophen-Induced Changes in Soil–Plant Nutrient Dynamics: A Radish System Study

Laidy Bayena · Alejandra Ayulo-Cumpalli · Jessica I. Nieto-Juárez · Héctor Tobón · y 3 más

Pharmaceutical residues in agricultural substrates may modify contaminant retention and nutrient dynamics, potentially affecting plant growth and nutrient allocation. This study investigated the adsorption of acetaminophen (ACE) onto washed coarse river sand and its effects on substrate physicochemical properties, elem...

Relationship between atypical language lateralization and cognition in pediatric patients with drug-resistant focal epilepsy: role of working memory

Johan S. Grisales-Cárdenas · Tania Jaramillo-Gil · Carlos R. Tolosa-Gaviria · Alejandro Herrera-Trujillo · y 5 más

Introduction Language lateralization is typically characterized by left-hemisphere dominance; however, atypical language organization occurs more frequently in pediatric patients with drug-resistant focal epilepsy (DRFE), likely reflecting adaptive neuroplastic mechanisms. Because surgical treatment is the standard of...
