Anion–π Interaction‐Regulated Ion Generation and High Piezoionic Response in Ultrasoft Low‐Salinity Hydrogels

open access: yesAngewandte Chemie, EarlyView.
The first hydrogel system employing anion–π interactions as a central design motif is developed. The cooperative aromatic–phosphate interaction motif provides dynamic cohesion and is proposed to regulate the separation and transport of water‐derived ionic species, achieving high piezoionic response in injectable, self‐healing, ultrasoft, low‐salinity ...

Anatomical substrate and scalp EEG markers are correlated in subjects with cognitive impairment and Alzheimer’s disease

open access: yesFrontiers in Psychiatry, 2011
Dementia is a syndromic diagnosis, encompassing various stage of severity and different anatomo-physiological substrates. The hippocampus is one of the first and most affected brain regions affected by both Alzheimer’s disease (AD) and mild cognitive ...

Preserving Motor Features by Alternative Re‐Referencing to Remove Heart Artifact on the Stentrode

open access: yesAdvanced Science, EarlyView.
Endovascular brain‐computer interfaces record neural activity from within cerebrovasculature, at the expense of electrocardiogram contamination. Band‐limited independent component analysis separates this heart‐based artifact from task‐relevant neural activity in each frequency band, enabling the reconstruction of cleaner neural recordings without the ...

Elevated Resting State Gamma Oscillatory Activities in Electroencephalogram of Patients With Post-herpetic Neuralgia

open access: yesFrontiers in Neuroscience, 2018
In acute and ongoing pain, the spontaneous oscillatory activity of electroencephalogram (EEG) has been characterized by suppression of alpha band oscillations and enhancement of gamma band oscillations.

Respiration organizes gamma synchrony in the prefronto-thalamic network

open access: yesScientific Reports, 2023
Multiple cognitive operations are associated with the emergence of gamma oscillations in the medial prefrontal cortex (mPFC) although little is known about the mechanisms that control this rhythm. Using local field potential recordings from cats, we show

HD‐tDCS Restores Perivascular AQP4 Polarization via PPARγ Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice

open access: yesAdvanced Science, EarlyView.
HD‐tDCS promotes recovery after intracerebral hemorrhage by enhancing PPARγ‐dependent astrocyte remodeling in a mouse model of ICH. This process suppresses proinflammatory astrocytic activation, restores perivascular AQP4 repolarization, and improves glymphatic influx and efflux, thereby facilitating hematoma and perihematomal edema clearance and ...

Scalp Electroencephalogram-Derived Involvement Indexes during a Working Memory Task Performed by Patients with Epilepsy

open access: yesSensors
Electroencephalography (EEG) wearable devices are particularly suitable for monitoring a subject’s engagement while performing daily cognitive tasks. EEG information provided by wearable devices varies with the location of the electrodes, the suitable ...

High-frequency bioelectrical activity of the brain in the diagnosis of epilepsy

open access: yesЭпилепсия и пароксизмальные состояния, 2018
Recent studies show that the brain gamma activity includes both the gamma rhythm (standard EEG) and high frequency (100-1000 Hz) as well as super-high (>1000 Hz) frequency oscillations, as recorded by electrocorticography.

Influence of lack of night sleep on the cognitive set by indicators of EEG rhythms coupling

open access: yesСоциально-экологические технологии, 2020
The aim of the study is investigation of nighttime sleep effect on the performance of a cognitive setting in terms of the coupling of EEG rhythms. The coupling of 5 rhythm: beta-1, beta-2, gamma, alpha and theta rhythms of EEG during the formation and ...

SPSB1 Promotes Subcutaneous Adipose Hyperplasia in Facial Port‐Wine Stains by Controlling HDAC1 Degradation and Stability Through Two Distinct Proteolytic Pathways

open access: yesAdvanced Science, EarlyView.
In PWS‐ASPCs, FOSL1 drives the expression of SPSB1. SPSB1, as part of the ESC complex, further binds to HDAC1 and promotes K29‐linked and K48‐linked polyubiquitination of HDAC1. These modifications facilitate the degradation of HDAC1 through the ALP and UPS pathways, respectively.
