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 ...

Full Clinical Pathological and Bacteriological Investigation of a Giant Nasal Polyp Associated With the Developing Apex of the Permanent Fourth Premolar (Triadan 108) in a 3‐year‐old Connemara Filly: A Case Report

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
A 3‐year‐old Connemara X filly presented with unilateral nasal discharge and facial swelling. Diagnostic imaging revealed a soft tissue mass with mineralisation and dental pathology (108). Histopathology confirmed a fibro‐inflammatory polyp. This case highlights a rare equine sino‐nasal polyp associated with endodontic disease, demonstrating a ...

Research progress of the pathogenesis of atlantoaxial dislocation caused by rheumatoid arthritis

Chinese Journal of Contemporary Neurology and Neurosurgery, 2018
Rheumatoid arthritis (RA) is a chronic, consumptive, autoimmune disease characterized by arthrosis symptoms. It often invades the joints. The early manifestation of RA is invasion of joint soft tissue by synovitis, which can destory the role of joint ...

Comparison of Two Posterior Minimally Invasive Approaches for Odontoid Fractures: Midline Nuchal Ligament Approach vs. Paramedian Muscle‐Splitting Approach

Orthopaedic Surgery, Volume 18, Issue 1, Page 74-83, January 2026.
The midline nuchal ligament approach yields clinical outcomes similar to those of the paramedian muscle‐splitting technique for odontoid fractures, while offering a more stable surgical procedure and reducing iatrogenic injury to the cervical posterior muscles and the greater occipital nerve.
