Tribological behavior of concave bronze surfaces textured by CNC micromachining

Esteban Rave · J Sebastián Rudas · Alejandro Toro · Cesar A Isaza M

Abstract In the field of tribology, surface texturing is crucial because it has proven highly effective in reducing the coefficient of friction (COF), mitigating wear, and regulating hydrodynamic properties in mechanical systems. It also offers significant benefits for energy efficiency in plain bearings widely used in...

Redefining the Evolution of Pulpal Pathology: Inflammasomes as Central Integrative Hubs and Biological Switches Governing the Transition From Reversible to Irreversible Pulpal Inflammation Beyond Symptom‐Based Classification

Néstor Ríos‐Osorio · James L. Gutmann · Tatiana M. Botero · Nessrin Taha · y 4 más

ABSTRACT Background The transition from reversible to irreversible pulpitis remains inadequately defined at the molecular level. Current classifications rely largely on clinical symptoms rather than objective biological determinants, limiting diagnostic precision and therapeutic decision‐making. Objectives To integrate...

Measurement of the Higgs boson total decay width using the H → W W → e ν μ ν decay channel in proton-proton collisions at s = 13 TeV

A. Hayrapetyan · V. Makarenko · A. Tumasyan · W. Adam · y 195 más

The Higgs boson (H) decay width is determined from the ratio of off- and on-shell production of H → W W → e ν μ ν using proton–proton collision data corresponding to an integrated luminosity of 138 fb − 1 collected at s = 13 TeV by the CMS experiment at the Large Hadron Collider. The off-shell signal strength is measur...

Is SORL1 a common genetic target across neurodegenerative diseases? A multi-ancestry biobank study

Marzieh Khani · Sheila N Yeboah · Catalina Cerquera-Cleves · Alexandra Kedmi · y 24 más

Abstract SORL1, the gene encoding the SORLA protein, has arisen as a potential therapeutic target for Alzheimer’s disease (AD). Studies suggest that restoring SORLA function or its trafficking pathways, particularly the SORLA–retromer recycling system, may offer a promising strategy to slow or halt AD progression. Whil...

Fungal endophytes of cactus ( Stenocereus spp.) as a potential alternative to alleviate drought stress in juveniles of Theobroma cacao L. ICS95

Karen Sofía Trujillo-Ortigoza · Angelis Marbello-Santrich · Juliana González-Tobón · Fermín Rada · y 2 más

ABSTRACT Theobroma cacao , one of Colombia’s most socially significant crops, faces productivity challenges due to drought. This stress can reduce growth, leaf area, and stomatal conductance ( K s ) and generate reactive oxygen species. Therefore, exploring solutions to enhance drought tolerance is crucial. This study...

Fuentes no convencionales de energía en la cadena del aceite de palma y del aceite de cocina usado como oportunidad de descarbonización en la aviación colombiana

Camilo Bayona Roa

La descarbonización del sector aeronáutico en Latinoamérica exige fuentes energéticas sostenibles que reduzcan las emisiones de dióxido de carbono. El presente trabajo reevalúa el potencial energético de las cadenas del aceite de palma y del aceite de cocina usado (ACU) en Colombia como rutas complementarias para la pr...

Edible clay minerals and related layered materials for loading and delivery of food bioactives: interaction mechanisms, applications, and safety—A mixed systematic–narrative review

Oscar Danilo Guerra Ceballos · Diego Alejandro Rueda Cadavid · Germán Ayala Valencia · Wilson Daniel Caicedo Chacon

Abstract Edible clay minerals are emerging as promising food-grade carriers for the stabilization and delivery of sensitive bioactive compounds, including polyphenols, vitamins, peptides, and essential oils. This systematic review with mechanistic narrative synthesis examines how clay architecture (lamellar smectites,...

Experience and outcomes of kidney transplantation in a Colombian referral center

Maricel Licht-Ardila · Diana Carolina Velasquez-Romero · Alexandra Hurtado-Ortiz · Alejandra Mendoza-Monsalve · y 8 más

Background Kidney transplantation remains the most effective therapy for End-Stage Renal Disease. While global outcomes have improved, data from Latin America are limited. Objective to describe the institutional experience of a national kidney transplant program in Colombia and to analyze patient and graft survival, ac...

ERDHEIM‐Chester Disease: Two Fatal Cases With Unusual Presentations

Ribero‐Vargas Daniel Andres · C. Álvarez Payares José · Murillo‐Pérez Juliana

ABSTRACT We present two fatal cases of Erdheim‐Chester disease (ECD) with unusual presentations: one featuring predominant gastrointestinal involvement with steatorrhea, nodular gastroduodenitis, and extensive visceral infiltration, and another with constrictive pericarditis and pachypleuritis. Both cases displayed cha...
