Electroacupuncture Modulates Multiple Pathways for Neuroprotection and Neurorepair in Ischemic Stroke

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
EA exerts therapeutic effects in ischemic stroke through multiple mechanisms: it alleviates acute injury by suppressing neuroinflammation, excitotoxicity, oxidative stress, apoptosis, pyroptosis, ferroptosis, autophagy dysregulation, and blood–brain barrier disruption, while enhancing cerebral blood flow, angiogenesis, and neurogenesis to support ...

Freshwater amphibians and squamates from Villeveyrac (lower Campanian; Hérault, France): palaeodiversity, palaeoenvironment and implications for the Late Cretaceous palaeobiogeography of the European herpetofauna

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...
