A General Cyanine‐Based Platform for Designing Robust Dual‐Channel Near‐Infrared Fluorescent and Photoacoustic Probes

Advanced Functional Materials, EarlyView.
The study presents a general cyanine‐based platform CySN for designing robust dual‐channel near‐infrared fluorescent (NIRF) and photoacoustic (PA) probes with high ratiometric signals change. CySN enables the construction of highly sensitive and selective dual‐channel NIRF/PA probes for both small molecule and enzyme biomarkers (H2O2, esterase ...

Multimodal acoustic-electric trigeminal nerve stimulation modulates conscious perception

NeuroImage
Multimodal stimulation can reverse pathological neural activity and improve symptoms in neuropsychiatric diseases. Recent research shows that multimodal acoustic-electric trigeminal-nerve stimulation (TNS) (i.e., musical stimulation synchronized to ...

ON THE QUANTITY OF ELECTRICITY AND THE ENERGY IN ELECTRICAL STIMULATION [PDF]

Journal of General Physiology, 1936
Weiss's and Hoorweg's laws are discussed with respect to the dynamics of the excitatory process. The former is shown to have a simple basis which is inadequate, however, because it implies a constant rate of subsidence of the state of excitation. Hoorweg's law does not follow logically from the same basis so the two laws do not represent the same ...

Electric Field Model of Transcranial Electric Stimulation in Nonhuman Primates: Correspondence to Individual Motor Threshold

IEEE Transactions on Biomedical Engineering, 2015
Objective: To develop a pipeline for realistic head models of nonhuman primates (NHPs) for simulations of noninvasive brain stimulation, and use these models together with empirical threshold measurements to demonstrate that the models capture individual

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites

Advanced Functional Materials, EarlyView.
The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

Advanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Integrating electric field modeling and neuroimaging to explain inter-individual variability of tACS effects

Nature Communications, 2019
Electrical stimulation of the brain can have variable effects, perhaps because of individual differences in brain structure which produce differences in the electric fields.

WAND: A 128-channel, closed-loop, wireless artifact-free neuromodulation device [PDF]

arXiv, 2017
Closed-loop neuromodulation systems aim to treat a variety of neurological conditions by dynamically delivering and adjusting therapeutic electrical stimulation in response to a patient's neural state, recorded in real-time. Existing systems are limited by low channel counts, lack of algorithmic flexibility, and distortion of recorded signals from ...

Direct electric stimulation to increase cerebrovascular function

Frontiers in Systems Neuroscience, 2015
Various conditions affecting the cerebral vasculature may lead to cumulative damage and thus deterioration of brain function, in what has been called vascular cognitive impairment (Gorelick et al., 2011).
