Accumulating evidence has provided a causative role of zinc (Zn(2+)) in neuronal death following ischemic brain injury. Using hypoxia model primary cultured cortical neurons with hypoxia-inducing chemicals, cobalt chloride (1 mM CoCl2), deferoxamine (3 DFX), and sodium azide (2 NaN3), we evaluated whether Zn(2+) is involved hypoxic death. The chemicals rapidly elicited intracellular release/accumulation viable neurons. immediate addition the chelator, CaEDTA or...
Silicon monoxide (SiO), which exhibits better cyclability compared to silicon while delivering higher capacity than that of graphite, is an adequate material for the development lithium-ion batteries (LIBs) having energy densities. However, incorporating silicon-based materials including SiO into stable graphite anode inevitably degrades not only cycle life but also calendar LIBs, little known about their aging mechanisms. Here, SiO-induced thermal instability graphite/SiO composite...
The capsaicin-sensitive vanilloid receptor (VR1) was recently shown to play an important role in inflammatory pain (hyperalgesia), but the underlying mechanism is unknown. We hypothesized that pain-producing mediators activate capsaicin receptors by inducing production of fatty acid agonists VR1. This study demonstrates bradykinin, acting at B2 bradykinin receptors, excites sensory nerve endings activating via 12-lipoxygenase metabolites arachidonic . finding identifies a might be targeted...
A chronically implantable, wireless neural interface device will require integrating electronic circuitry with the interfacing microelectrodes in order to eliminate wired connections. Since integrated circuit (IC) dissipates a certain amount of power, it raise temperature surrounding tissues where is implanted. In this paper, thermal influence 3-D Utah electrode array (UEA) implanted brain was investigated by numerical simulation using finite element analysis (FEA) and experimental...
This article proposes a new electrolyte engineering strategy with “zwitterion” molecules, which reduce side reactions by adsorbing onto the zinc surface. The 6-aminohexanoic acid enables uniform deposition and reduces dendrite growth.
Abstract As an alternative to Li‐ion batteries, aqueous Zn batteries have gained attention due the abundance of metal, low reduction potential (–0.76 V vs. standard hydrogen electrode), and high theoretical capacity (820 mAh g –1 ) multivalent 2+ ion. However, growth dendrites formation irreversible surface reaction byproducts pose challenges for ensuring a long battery lifespan commercialization. Herein, Cu foil coated with single‐walled carbon nanotube (SWCNT) layer using facile doctor...
Purpose The objective of this study was to examine the imaging features classic mass-forming intrahepatic cholangiocarcinoma (MICC) and nonclassic hypervascular MICC on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid–enhanced magnetic resonance imaging. Methods Twenty pathologically confirmed MICCs were included. Two radiologists retrospectively reviewed characteristics T2-weighted imaging, diffusion-weighted dynamic contrast-enhanced images, hepatobiliary phase (HBP) each MICC....
Due to the trade-off between their electrical/electrochemical performance and underwater stability, realizing polymer-based, high-performance direct cellular interfaces for electrical stimulation recording has been very challenging. Herein, we developed transparent conductive based on a water-stable, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) film via solvent-assisted crystallization. The crystallized PEDOT:PSS polyethylene terephthalate (PET) substrate exhibited...
Study Design. A three-dimensional finite element model of intact lumbar spine was constructed and four surgical models implanted with ball-and-socket artificial discs different radii curvature were compared. Objective. To investigate biomechanical effects the disc using analysis. Summary Background Data. Total replacement (TDR) has been accepted as an alternative treatment because its advantages over spinal fusion methods in degenerative disease. However, influence not fully understood....
Despite recent interest in using zebrafish human disease studies, sparked by their economics, fecundity, easy handling, and homologies to humans, the electrophysiological tools or methods for are still inaccessible. Although exhibit more significant larval-adult duality than any other animal, most studies biased larvae these days. The results of larval not only differ from those conducted with adults but also unable delicately manage electroencephalographic montages due small size. Hence, we...
Helicobacter pylori is a gastrointestinal pathogen known to be associated with cardiovascular disease (CVD). However, most analyses about the effect of H. infection have been done in patients history CVD but not healthy subjects. We evaluated association between and subclinical atherosclerosis by using cardiac multidetector computed tomography (MDCT) subjects without previous CVD. From December 2007 February 2014, 463 who underwent rapid urease test (CLO test), pulse-wave velocity (PWV)...
Direct visualization of the dissolution and deposition reactions in Se cathodes resolves competitive nucleation growth behaviors dependent on depletion electrolyte-soluble polyselenides.
Abstract Electrocorticogram (ECoG) is an electrophysiological signal that results from the summation of neuronal activity near cortical surface. To record ECoG signals, scalp and skull are surgically opened electrodes placed on surface, either epidurally or subdurally. Owing to its improved spatiotemporal resolution quality compared with electroencephalography, it widely used diagnose treat neurological disorders in clinical settings for several decades, despite invasiveness ECoG. Recently,...
Abstract The triboelectric nanogenerator (TENG) is gaining recognition as a highly promising, eco‐friendly self‐powered device for the growth of Internet Things (IoT). To improve performance TENGs, diverse materials are employed interlayers. However, challenges related to cost and stability persist. Herein, strategy that incorporates ion‐containing electrolyte polymers interlayers presented. This approach effectively mitigates charge decay maximizes TENG efficiency by leveraging high...
