Sterile Vegetations in Malignancy: A Rare Case of Nonbacterial Thrombotic Endocarditis in a Patient with Metastatic Melanoma

Libardo Rueda Prada · Alejandro Fabrega Gerbaud · Marta Berguido de la Guardia · Juan C. Martinez Morales · y 2 más

Background and Clinical Significance: Nonbacterial thrombotic endocarditis (NBTE) is a sterile fibrin-platelet valvular condition associated with malignancy and hypercoagulable states. It produces friable vegetations prone to systemic embolization, often presenting as multifocal ischemic stroke. While modestly linked t...

Mitochondrial donation recapitulates physiological niche signalling to promote metabolic plasticity, expansion, and engraftment of hematopoietic progenitors

Maroun Khoury · Radmila Velarde · Angela Court · Gino Nardocci · y 9 más

Abstract Umbilical cord blood (UCB) transplantation effectively treats pediatric hematologic disorders, but insufficient multipotent progenitors delay immune reconstitution, severely restricting its clinical application in adults. Here, we established that mesenchymal stromal cells’ mitochondrial donation to UCB hemato...

Economic Entropy and the Cobb-Douglas Function: A Scientometric Analysis

Isabel Cristina Betancur-Hinestroza · Nini Johana Marín-Rodríguez · Francisco J. Caro-Lopera · Éver Alberto Velásquez Sierra

Economic entropy, as an emerging concept in econophysics, has gained increasing relevance in the analysis of complex systems characterized by uncertainty, nonlinearity, and out-of-equilibrium dynamics. However, its integration into conventional economic modeling—particularly in production functions such as the Cobb–Dou...

Enhanced heat transfer characteristics of Casson–Williamson trihybrid nanofluid under quadratic thermal radiation over a porous stretching surface

Gopinath Mandal · Pradeep Kaswan · Arindam Sarkar · Mohamed Kezzar

Purpose This study aims to present a novel numerical investigation of steady two-dimensional boundary-layer flow and heat transfer of a Casson–Williamson tri-hybrid nanofluid over a permeable stretching surface, incorporating quadratic thermal radiation and velocity slip effects. The tri-hybrid nanofluid is formed by d...

Pedro Ordunez · Andres Rosende · Maria Florencia Grande Ratti · Donald J DiPette · y 33 más

Abstract Background HEARTS in the Americas is the regional adaptation of the WHO Global HEARTS Initiative. This paper presents Phase 3 of HEARTS 2.0, an evidence-informed process to prioritize clinical and health-system interventions to support the operationalization of integrated cardiovascular, kidney, and metabolic...

Paniculitis mesentérica y disfunción linfática: Hallazgos clínicos e imagenológicos de un caso inusual

David Mejía · Mateo J. Murcia-Ramos · Samuel Salgado-Uribe · Daniela Arbeláez-Lelión

Introduction. Mesenteric panniculitis (MP) is a rare, benign fibro-inflammatory disease of the mesenteric adipose tissue, most common in adult men, whose etiology is not fully elucidated. Clinical case. We present the case of a 40-year-old female patient with a history of appendectomy and gastric sleeve surgery, who pr...

Altered brain vascularization and transcriptional changes in embryos lacking ABCA1 support a role of cholesterol in brain angiogenesis

Brenda Becerra · Oriana Ramírez-Herrera · Javiera Barrios · Josefina Madrid · y 9 más

Introduction Lipoproteins are the main lipid carriers in extracellular fluids and mediate the exchange of hydrophobic molecules between cells and their environment in animals, including cholesterol. Lipoprotein metabolism has been implicated in the regulation of angiogenesis, suggesting that cholesterol is important fo...
