In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

open access: yesCytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Characteristics and Stability of Valerian Essential Oil Nanoemulsion: A Comparison Between Ultrasonication and Microfluidization

open access: yesFood Science &Nutrition, Volume 14, Issue 6, June 2026.
The graphical abstract illustrates the preparation and stability evaluation of valerian essential oil (VEO) nanoemulsion produced using ultrasonication and microfluidization in phosphate buffer (PB) and distilled water (DW). Both high‐energy methods successfully generated nano‐sized emulsions; however, ultrasonication produced smaller droplet sizes and

Impact of Isolation Techniques on the Content of Small Extracellular Vesicles

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT An important topic of discussion amongst the extracellular vesicle (EV) research field is which genetic materials are considered true constituents of EV cargo. What were once regarded as non‐EV components have now evolved to be potentially essential to EV composition, serving as key mediators in communication.

Enterococcus faecalis Extracellular Vesicles Deliver the Bacterial GTPase Obg to Hijack mTOR Signalling in Hepatocellular Carcinoma

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
E. faecalis is enriched in HCC tissue and can promote liver tumourigenesis by activating mTOR signalling pathway. Obg derived from E. faecalis extracellular vesicles (EVs) is a GTPase physically interacts with mTOR, and acts as an interkingdom activator of mTOR. EF‐Obg expression level in HCC tissue correlates with poor prognosis in HCC patients.
