The Role of Extracellular Vesicles in Transient Ischaemic Attacks and Ischaemic Stroke: A Systematic Review

open access: yesJournal of Extracellular Biology, Volume 5, Issue 3, March 2026.
Both transient ischaemic attack (TIA) and ischaemic stroke lead to an increase in individual cellular‐derived populations of extracellular vesicles (EVs), including endothelial, platelet and leukocyte derived. These EVs have downstream roles in the pathophysiological events associated with TIA and stroke, including dysregulated inflammation and ...

Urban Pollution Promotes Biotic Simplification of the Zooplankton Community in Ponds in Northeastern Brazil

open access: yesFreshwater Biology, Volume 70, Issue 6, June 2025.
ABSTRACT Pollution significantly impacts aquatic biodiversity by limiting the species pool. However, considerable uncertainty remains regarding which community attributes should be used to demonstrate the effects of this anthropogenic disturbance. We propose that zooplankton taxonomic biodiversity could serve as a reliable pollution indicator in lentic

Patterns of Gene Family Evolution and Selection Across Daphnia

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
This study examines gene family dynamics within Daphnia species, using comparative genomics to explore adaptive expansion in gene families, particularly those related to stress response. Findings reveal general trends in gene turnover and selection, although most changes are species‐specific, highlighting complex evolutionary patterns.

Selective Synthesis of Tetrahydroisoquinoline and Piperidine Scaffolds by Oxidative Ring Opening/Ring Closing Protocols of Substituted Indenes and Cyclopentenes

open access: yesChemistryOpen, Volume 14, Issue 5, May 2025.
Synthesis under stereocontrol of some novel tetrahydroisoquinoline and functionalized piperidine derivatives from substituted indenes or cyclopentenes is described. The key steps of the transformation are an oxidative ring cleavage across the olefin bond, followed by cyclization under double reductive amination with primary chiral amines through ring ...

How Can Unique Alkaline Soda Waters Be Managed and Restored? Lake Neusiedl as the Largest Threatened European Example

open access: yesEcohydrology, Volume 18, Issue 2, March 2025.
ABSTRACT Inland alkaline soda waters (ASW), such as Lake Neusiedl (LN), represent some of the most stable alkaline natural environments and unique ecosystems on Earth. Their European hotspot is located in Central Europe, where LN stands as the largest threatened representative, giving it practical importance.

Synaptic Targets and Cellular Sources of CB1 Cannabinoid Receptor and Vesicular Glutamate Transporter‐3 Expressing Nerve Terminals in Relation to GABAergic Neurons in the Human Cerebral Cortex

open access: yesEuropean Journal of Neuroscience, Volume 61, Issue 1, January 2025.
In the human cerebral cortex, GABAergic boutons originating from diverse presynaptic cell types, some expressing CB1 cannabinoid receptor, make synapses mainly with dendritic shafts and spines. One quarter of GABAergic CB1 immunopositive nerve terminals also expresses the type 3 vesicular glutamate transporter (VGLUT3).
