Oral Microbiota, the Oral–Brain Axis, and Neurodegeneration: Mechanisms and Dietary Modulation

Justyna Godos · Giuseppe Caruso · Giuseppe Mainas · Agnieszka Micek · y 12 más

The oral microbiota represents a complex and dynamic microbial ecosystem that plays a critical role in preserving both oral and systemic homeostasis. Emerging evidence suggests that alterations in oral microbial milieu (dysbiosis) may contribute to the pathogenesis of neurodegenerative disorders, especially Alzheimer’s...

Cellular effects of combined Ctn-2 peptide and doxorubicin treatment in breast cancer cells: A preliminary study of membrane interaction, ROS production, and cell cycle distribution

Ana María Sepúlveda · Marcela Manrique-Moreno · Sofía Echeverri-Gaviria · Gloria A. Santa-González

Triple-negative breast cancer (TNBC) lacks targeted therapies and is commonly treated with doxorubicin, whose efficacy is limited by toxicity and chemoresistance. Bioactive peptides have emerged as potential adjuvants due to their membrane activity and antitumor properties. To address the potential of the combined trea...

Quasi-Experimental Evaluation of the Association Between Payments for Ecosystem Services and Satellite-Based Vegetation Dynamics in Cundinamarca, Colombia

Andres Vergara Narvaez · Tania Jiménez Castilla · Gastón Ballut-Dajud

Payments for Ecosystem Services (PES) are increasingly used to promote conservation, but evidence of their biophysical outcomes remains mixed because participation is rarely assigned at random. This study assessed the association between participation in the Yo Protejo ¡Agua para Todos! PES program and satellite-based...

Intravascular projectile embolism from firearm injuries: How did it get there?

Carlos Felipe Marín-Díaz · Santiago Quiceno-Ramírez · Karen Juliana Salinas-Castro · Erika Andrea Rincón-Escobar

Intravascular projectile embolization is a rare but potentially fatal complication of penetrating firearm injury, in which a low-energy projectile enters the cardiovascular system and migrates to a site remote from the wound of entry. Because the projectile comes to rest far from its expected trajectory, the diagnosis...

In Vitro Inhibition of Digestive Enzymes by Leaf Metabolites from Neurolaena lobata (L.) R. Br. ex Cass. (Asteraceae)

Yohum Lozada-Diaz · Oscar J. Patiño-Ladino · Juliet A. Prieto-Rodríguez

Digestive enzymes such as pancreatic lipase (PL), α-glucosidase (AG), and α-amylase (AA) play key roles in the hydrolysis of dietary lipids and carbohydrates and are therefore relevant biochemical targets for evaluating compounds with potential to modulate postprandial metabolic responses. Neurolaena lobata (L.) R. Br....

Optimizing Photogrammetry Parameters for 3D Reconstruction of Fresh Brain Specimens

Carlos A. Rueda-Pérez · María-Camila Valencia-Loaiza · Paula Vega-Cordoba · Juliana Tobón · y 11 más

Abstract Photogrammetry has become an essential tool in medical and research fields for generating high-fidelity 3D models from 2D images. However, optimizing the imaging and processing parameters remains a challenge, particularly for fresh brain specimens, where repeated imaging is not feasible. This study systematica...
