Boron‐Doped Nano‐Crystalline Coated Carbon Fibers for Phasic Dopamine Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
This uniform coating presents a mix of graphitic and diamond‐like carbon to create a mechanically and electrically robust alternative for the electrochemical detection of dopamine. The electrodes in this work possess the equivalent sensitivity to the state‐of‐the‐art FSCV dopamine detecting electrodes, whilst demonstrating an ability to withstand ...

A 3D Astrocyte Microenvironment Model Enables Rapid Ca2+‐Resolved Analysis and Therapeutic Modulation of Oxidative Neuroinflammation

open access: yesAdvanced Healthcare Materials, EarlyView.
This work presents ARC‐3D, a soft 3D model that recreates how brain support cells, called astrocytes, react to oxidative stress. The system visualizes rapid calcium changes and inflammatory signals, and shows how the drug KDS12025 can protect cells from damage. ARC‐3D offers a simple, reliable way to study early drivers of brain inflammation.

Control of cell division in the adult brain by heparan sulfates in fractones and vascular basement membranes [PDF]

open access: yes, 2010
Regulation of cell division in adult tissues and organs requires the coordination of growth factors at the surface of potentially-dividing cells in specific anatomic loci named germinal niches.

Engineered ETS1‐Nanoconjugate Restores Immune Homeostasis through Dual Immune‐Vascular Modulation in Relapsing and Progressive Multiple Sclerosis

open access: yesAdvanced Healthcare Materials, EarlyView.
The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T

Neoplastic meningitis

open access: yesSeminars in Neurology, 2004
Neoplastic meningitis (NM) is a common problem in neuro-oncology occurring in approximately 5% of all patients with cancer, and is the third most common site of CNS metastases. NM is a disease affecting the entire neuraxis, and therefore clinical manifestations are pleomorphic affecting the spine, cranial nerves, and cerebral hemispheres.

A Closer Look at the Global Management of Spina Bifida: The Implementation of Endoscopic Third Ventriculostomy in the Treatment of Spina Bifida-Related Hydrocephalus in Africa [PDF]

open access: yes, 2018
Spina bifida, specifically myelomeningocele, is a debilitating neural tube defect that affects patients and families throughout the world. Traditional management and treatment methods are described, followed by an explanation of why this is often ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

open access: yesAdvanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Imaging diagnosis: magnetic resonance imaging of diffuse leptomeningeal oligodendrogliomatosis in a dog with "dural tail sign" [PDF]

open access: yes, 2018
A case of diffuse leptomeningeal oligodendrogliomatosis affecting the brain and spinal cord of a dog is presented. A 7.5-year old, male neutered Staffordshire bull terrier presented for evaluation of a chronic history of tetraparesis and seizures, with a

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...
