Alternativa de reconstrucción posterior a hemiglosectomía con colgajo submentoniano. Serie de casos

Rogers Leonardo Baquero-García · Juan De Francisco-Zambrano · Camila Alejandra Camila Alejandra · Laura María Riveros-Loaiza

Introducción. El carcinoma escamocelular de lengua representa la variante histológica más frecuente de las patologías malignas de la cavidad oral (90 % de los casos). Tiene múltiples factores de riesgo, con mayor asociación al trauma recurrente, tabaquismo y alcoholismo. El pilar del tratamiento es quirúrgico, siendo l...

DFT Analysis of Frontier Orbitals (HOMO-LUMO) of Polylactic Acid Functionalized with N-Hydroxysuccinimide and N-Sulfosuccinimide for the Adsorption of the Heavy Metals Nickel, Arsenic, and Lead

Yuly Maldonado-Morales · Rodrigo Ortega-Toro · Joaquin Hernandez-Fernandez

Polylactic acid (PLA) is a biopolymer made from starch that is both sustainable and low-cost. But its chemical inertness limits its application in the removal of heavy metals from aqueous environments. This study addresses the limitations by functionalizing PLA with N-hydroxysuccinimide (NHS) and N-sulfosuccinimide (S-...

Obtention and Characterisation of Gelatine-Based Hydrogels Reinforced with the Amino Acids Cysteine (Cy) and Glutamine (Gt)

Heidi Fonseca Florido · Ángel Villabona-Ortiz · Rodrigo Ortega-Toro

The use of conventional plastics represents a major environmental concern, as approximately 79% ultimately accumulate in landfills or natural ecosystems. Consequently, there is growing interest in the development and application of renewable materials for food packaging. Therefore, the aim of this study was to develop...

Nanopore-based 18S rRNA metabarcoding reveals Hepatozoon lineages from ectoparasites

Richard Said Thomas · Antonella Bacigalupo · María Carolina Silva-de la Fuente · Nicol Quiroga · y 13 más

Abstract Inverse surveillance seeks to identify potential pathogens before diseases emerge in populations. In this study, we conducted a molecular survey of eukaryotic vector-borne pathogens (VBPs) within ectoparasite species to anticipate disease outbreaks in animals and humans. We analysed fleas, lice, mites, ticks a...

Artificial Intelligence and Cloud Computing for a New Generation of Corine Land Cover Maps in Colombia

Javier Espejo · Maycol Zaraza · Karen Bastidas · Ariel Perilla · y 9 más

The generation of reliable and up-to-date national land cover information is essential for environmental management, climate action, and territorial planning. In Colombia, the CORINE Land Cover Colombia (CLCC) framework has been the official reference for land cover monitoring since 2000, traditionally updated through...

Association of CSN1S1, CSN2, CSN1S2, CSN3 and β-LG genes with productive and reproductive traits in the Lucerna breed

Darwin Hernández-Herrera · Alejandra Alvarez Múnera · Luis Gabriel González Herrera · Juan Carlos Rincón Flórez

Objective. To associate the main allelic variants of the CSN1S1, CSN2, CSN1S2, CSN3 and β-LG genes with the traits adjusted milk yield at 305 days (P305), age at first calving (AFC), calving interval (CI), mastitis positivity and perinatal mortality (PM) in Lucerna cattle. Materials and methods. Phenotypic values were...

Ion-Exchange Selectivity in Alginate Egg-Box Models: Effect of the G-Rich and M-Rich Microenvironment on the Stabilization of Divalent Metal Cations

Joaquín Hernández-Fernández · Rafael González-Cuello · Rodrigo Ortega-Toro

In this study, ion-exchange selectivity in alginate egg-box-type models containing guluronate-rich (PG) and mannuronate-rich (PM) microenvironments was investigated by density functional theory using a cluster–continuum approach in water. The objective was to determine how local sequence modulates the replacement of Ca...
