Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Scalp Neurofibroma Presenting with Hematoma After Trauma

, 2019
Neurofibromatosis (NF) type 1 is a hereditary, autosomal dominant neurocutaneous syndrome often accompanied by diffuse neurofibromas in the body, increased skin pigmentation (cafe-au-Iait spots) and central nervous system tumors. Neurofibromas are tumors

Short-channel regression in functional near-infrared spectroscopy is more effective when considering heterogeneous scalp hemodynamics. [PDF]

, 2020
Significance: The reliability of functional near-infrared spectroscopy (fNIRS) measurements is reduced by systemic physiology. Short-channel regression algorithms aim at removing systemic "noise" by subtracting the signal measured at a short source ...

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

The management of non-melanocytic skin malignancies of the scalp and calvarium

Indian Journal of Plastic Surgery, 2014
Background: The management of advanced cutaneous malignancies has been controversial. Thirteen patients with nonmelanoma skin neoplasias that had invaded the bone of the calvarium and scalp were treated in our centre. Objective: The purpose of this study

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

Advanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.

Malignant Peripheral Nerve Sheath Tumor of the Scalp: A Case Report [PDF]

Caspian Journal of Neurological Sciences
Background: Malignant peripheral nerve sheath tumors (MPNSTs) are uncommon tumors typically originating from somatic soft tissues or peripheral nerves. Instances of primary MPNSTs on the scalp are exceedingly rare.
