NON-TRAUMATIC DISPLACEMENT OF THE ATLANTO-AXIAL JOINT [PDF]

The Journal of Bone and Joint Surgery. British volume, 1968
1. Seven cases of non-traumatic anterior atlanto-axial displacement in young people are recorded. 2. Four of the seven patients showed evidence of neurological compression. All cases improved symptomatically with treatment, but five still show persistent radiological displacement. 3. The mechanism of the displacement is thought to be due to acquired

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 ...

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.
