This paper investigates the spatial distribution of electric field and current density in brain tissues induced by transcranial direct stimulation primary motor cortex. A numerical method was applied on a realistic human head model to calculate these distributions different structures, such as cortex, white matter, cerebellum, hippocampus, medulla oblongata, pons, midbrain, thalamus. The influence varying anode area, cathode injected also investigated. An electrode area one typically used...
Over the last two decades residential exposure to extremely low frequency magnetic fields (ELF MF) has been associated with childhood leukaemia relatively consistently in epidemiological studies, though causality is still under investigation. We aimed estimate cases of that might be attributable ELF MF European Union (EU27), if associations seen studies were causal. estimated distributions using identified existing literature. Individual integrated a probabilistic mixture distribution...
Minimally invasive medical treatments for peripheral nerve stimulation are critically needed to minimize surgical risks, enhance the precision of therapeutic interventions, and reduce patient recovery time. Magnetoelectric nanoparticles (MENPs), known their unique ability respond both magnetic electric fields, offer promising potential medicine due dual tunable functionality. In this study a multi-physics modeling MENPs was performed, assessing capability be targeted through external fields...
Abstract Magnetoelectric nanoparticles (MENPs) are able to locally generate high electric fields when activated with human‐safe, low‐intensity magnetic fields. However, implanted as individual or randomly positioned small clusters, the induced decay very quickly distance, hampering effective tissue stimulation. Herein, a novel nano‐structured polymeric‐based MENPs‐loaded 3D system (ME‐Patch) is designed and optimized in terms of its electrical performances through holistic multi‐scale silico...
Deep transcranial magnetic stimulation (dTMS) has been recently used in several clinical studies as diagnostic and therapeutic tool. However, electric field (E) distributions induced the brain by dTMS are still unknown. This paper provides a characterization of E realistic human model due to 16 different coil configurations.The scalar potential finite-element method was calculate differentiating structures, e.g., cortex, white matter, anterior cingulated cerebellum, thalamus, hypothalamus,...
Objective: This study aimed to compare the effectiveness of tinnitus retraining therapy (TRT) with sound generators or open ear hearing aids in rehabilitation for a group subjects who, according Jastreboff categories, can be treated both approaches (borderline Category 1 and 2). Design: was prospective data collection parallel-group design which entailed that each subject randomly assigned one two treatments group: half were fitted binaurally generators, other aids. Both groups received same...
Extremely Low Frequency Electric (ELF-EF) and Magnetic Field (ELF-MF) exposure is caused by different types of sources, from those related to the production, transmission, distribution electric currents, technologies common use, such as domestic appliances or transportation. Establishing levels for general public a fundamental step in health risk management process but could be challenging due differences approaches used studies. The goal this study present an overview last years research...
Biological signal and image processing (BSIP) constitutes a major field of interest in both educational aspects research environments biomedical engineering. In fact, the physiological knowledge improvement wide variety innovative as well implementation many clinical procedures extensively makes use these concepts more or less sophisticated medical applications. this article, important links between BSIP modeling their derived synergies are particularly stressed. support aim, examples have...
The recent development of core-shell nanoparticles which combine strain coupled magnetostrictive and piezoelectric phases, has attracted a lot attention due to their ability yield strong magnetoelectric effect even at room temperature, thus making them promising tool enable biomedical applications. To fully exploit potentialities adapt use in vivo applications, this study analyzes, through numerical approach, behavior, shortly quantified by the coupling coefficient (α ME ), providing an...
Core-shell magnetoelectric nanoparticles (MENPs) have recently gained popularity thanks to their capability in inducing a local electric polarization upon an applied magnetic field and vice versa. This work estimates the magnetoelectrical behavior, terms of coupling coefficient (αME), via finite element analysis MENPs with different shapes under either static (DC bias) time-variant (AC external fields. With this approach, dependence performance on geometrical features can be directly...
In recent years there has been considerable interest in the study of glucose-induced dielectric property variations human tissues as a possible approach for non-invasive glycaemia monitoring. We have developed an electromagnetic sensor, and we tested vitro its ability to estimate glucose concentration different solutions with similarities blood (sodium chloride Ringer-lactate solutions), differing though lack any cellular components. The sensor was able detect effect over wide range...
Abstract Tinnitus is considered an auditory phantom percept. Recently, transcranial direct current stimulation (tDCS) has been proposed as a new approach for tinnitus treatment including, potential targets of interest, either the temporal and temporoparietal cortex or prefrontal areas. This study investigates compares spatial distribution magnitude electric field density in brain tissues during tDCS different targets. A numerical method was applied on realistic human head model to calculate...
Recent studies have shown that the specific application of transcranial direct current stimulation (tDCS) over cerebellum can modulate cerebellar activity. In parallel, transcutaneous spinal DC (tsDCS) was found to be able conduction along cord and functions. Of particular interest is possible use these techniques in pediatric age, since many pathologies injuries, which affect cortex as well circuits, are diffuse adults children. Up now, experimental on children completely missing therefore...
Abstract Magnetoelectric (ME) materials, especially in the form of core–shell nanoparticles, have gained increasing attention for their potential bioengineering applications. In particular, cobalt ferrite (CoFe 2 O 4 ) and barium titanate (BaTiO 3 nanoparticles stand out due to strong Magneto‐Electric properties.
