Salivary Extracellular Vesicles Separation: Analysis of Ultracentrifugation‐Based Protocols

open access: yesOral Diseases, Volume 31, Issue 3, Page 879-889, March 2025.
ABSTRACT Introduction The clinical potential of extracellular vesicles (EVs) is widely acknowledged, yet the standardization and reproducibility of its separation remain challenging. This study compares three protocols: ultracentrifugation (UC), UC with purification step (UC + PS), and a combined protocol using polymer‐based precipitation and UC (PBP +

Phloem sap from melon plants contains extracellular vesicles that carry active proteasomes which increase in response to aphid infestation

open access: yesJournal of Extracellular Vesicles, Volume 13, Issue 10, October 2024.
Abstract The morphogenesis of higher plants requires communication among distant organs throughout vascular tissues (xylem and phloem). Numerous investigations have demonstrated that phloem also act as a distribution route for signalling molecules being observed that different macromolecules translocated by the sap, including nucleic acids and proteins,

Male genitalia, hierarchical homology, and the anatomy of the bullet ant (Paraponera clavata; Hymenoptera, Formicidae)

open access: yesJournal of Morphology, Volume 285, Issue 9, September 2024.
We present a multimodal anatomy of the male genitalia of the bullet ant, Paraponera clavata. Using this as a model system, we expand and refine on the 5‐category system of homology classification proposed by Meneganzin et al. (2024) and we present evidence supporting the penis‐coxopod theory of male genitalic homology in male insects. Abstract The male
