A 3D subject-specific model of the spinal subarachnoid space with anatomically realistic ventral and dorsal spinal cord nerve rootlets

Fluids and Barriers of the CNS, 2017
Background The spinal subarachnoid space (SSS) has a complex 3D fluid-filled geometry with multiple levels of anatomic complexity, the most salient features being the spinal cord and dorsal and ventral nerve rootlets.

Clinical Study of Ultrasound‐Guided Modified Percutaneous Endoscopic Interlaminar Discectomy Combined With Medical Chitosan in Lumbar 4–5 Disc Herniation Treatment

Orthopaedic Surgery, EarlyView.
Ultrasound‐guided PEID plus medical chitosan can effectively reduce postoperative pain and perioperative complications, demonstrating superior clinical efficacy. ABSTRACT Objective Percutaneous endoscopic lumbar discectomy (PELD) is a preferred minimally invasive surgery for lumbar disc herniation (LDH); however, postoperative recurrence, nerve root ...

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Immunohistochemical profile of neurotrophins in human cranial dura mater and meningiomas

Oncology Reports, 2009
The immunohistochemical profile of neurotrophins and their receptors in the human cranial dura mater was studied by examining certain dural zones in specimens harvested from different regions (frontal, temporal, parietal and occipital). Dural specimens were obtained during neurosurgical operations performed in ten patients for surgical treatment of ...

Hydrogen Sulfide Mediating both Excitatory and Inhibitory Effects in a Rat Model of Meningeal Nociception and Headache Generation

Frontiers in Neurology, 2017
Background/purposeHydrogen sulfide (H2S) is a neuromodulator acting through nitroxyl (HNO) when it reacts with nitric oxide (NO). HNO activates transient receptor potential channels of the ankyrin type 1 (TRPA1) causing release of calcitonin gene-related

High‐altitude headache: Insights into pathophysiology and potential treatment implications

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude headache occurs during prolonged exposure to low oxygen, such as during ascent to high altitude. Several risk factors increase its likelihood, with the degree of hypoxia, often driven by rapid ascent to greater altitudes, being the most prominent factor.

Biosynthetic cellulose induces the formation of a neoduramater following pre-natal correction of meningomyelocele in fetal sheep A celulose biossintética induz a formação de uma neoduramáter na correção antenatal da meningomielocele em fetos de ovelhas

Acta Cirúrgica Brasileira, 2007
PURPOSE: The aim of this study was to compare the effectiveness of two dura-mater substitutes, namely human acellular dermal matrix (HADM) and biosynthetic cellulose (BC), in repairing, in utero, surgically-induced meningomyelocele (MMC) in fetal sheep ...

Evidence for progressive neurodegeneration in iatrogenic cerebral amyloid angiopathy

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Iatrogenic transmission of amyloid beta can cause cerebral amyloid angiopathy (CAA) and Alzheimer's disease (AD), but the relationship between these phenotypes is unclear. METHODS We retrospectively analyzed standardized neuropsychological and neuroimaging data from 11 patients with iatrogenic CAA (iCAA).

Cone beam computed tomographic myelography in horses with cervical vertebral compressive myelopathy

Equine Veterinary Journal, Volume 58, Issue 4, Page 1049-1060, July 2026.
Abstract Background While computed tomographic (CT) myelography is increasingly available and has been evaluated in alive horses, objective criteria for diagnosing cervical vertebral compressive myelopathy (CVCM) are lacking. Objectives To establish morphometric dimensions of the cervical vertebral canal and spinal cords from horses with CVCM and ...
