This paper presents the design, fabrication, and characterization of a microwave resonator as tool for concentration measurements liquid compounds. The sensing device is rectangular waveguide cavity tuned at 1.91 GHz, which exploits fundamental TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">101</sub> mode in transmission-type configuration. coupling structure optimized by means finite element code so to achieve high <i...
Background Electroporation, a method for increasing the permeability of membranes to ions and small molecules, is used in clinic with chemotherapeutic drugs cancer treatment (electrochemotherapy). Electroporation calcium causes ATP (adenosine triphosphate) depletion cell death could be novel treatment. This study aims at understanding relationship between applied electric field, concentration, efficacy. Methods In three human lines — H69 (small-cell lung cancer), SW780 (bladder U937...
Abstract The possibility of mimicking different types breast tissues to realize experimental phantoms has been investigated by measuring the complex permittivity polyethylene glycol mono phenyl ether (Triton X‐100) and distilled water solutions. In this respect, broad band electromagnetic characterization several mixtures, at concentrations, carried out in 0.5–12 GHz frequency range. good fitting between dielectric properties mammary that proposed stability against temperature range 18–30...
The aim of this preliminary investigation was to assess whether human peripheral blood lymphocytes which have been pre-exposed non-ionizing radiofrequency fields exhibit an adaptive response (AR) by resisting the induction genetic damage from subsequent exposure ionizing radiation. Peripheral four healthy donors were stimulated with phytohemagglutinin for 24 h and then exposed 20 1950 MHz (RF, dose, AD) at average specific absorption rate 0.3 W/kg. At 48 h, cells subjected a challenge dose...
This study explores the effect of continuous exposure to bright light on neuromelanin formation and dopamine neuron survival in substantia nigra. Twenty-one days after birth, Sprague–Dawley albino rats were divided into groups raised under different conditions exposure. At end irradiation period, sacrificed assayed for number tyrosine hydroxylase (TH)-positive neurons The exposed 20 or 90 showed a relatively greater neuromelanin-positive neurons. Surprisingly, TH-positive decreased...
The impact of pulse repetition rate (PRR) in modulating electroporation (EP) induced by nanosecond pulsed electric fields (nsPEFs) mammalian cells was approached here performing both biological and numerical analysis. Plasma membrane permeabilization viability Jurkat were analyzed after exposure to 500, 1.3 MV/m, 40 ns PEFs with variable PRR (2-30 Hz). A finite-element model used investigate EP dynamics a single cell under the same pulsing conditions, looking at time course transmembrane...
Reversible electroporation is used to increase the uptake of chemotherapeutic drugs in local tumor treatment (electrochemotherapy) by applying pulsing protocol (8 rectangular pulses, 1000 V/cm, 100 µs) standardized framework European Standard Operating Procedure on Electrochemotherapy multicenter trial. Currently, new electrochemotherapy strategies are under development extend its applicability tumors with different histology. Electrical parameters and drug type critical factors. A possible...
To investigate the influence of cell cycle on adaptive response (AR) induced by exposure human blood lymphocytes to radiofrequency fields (RF).Human peripheral in G(0)-, G(1)- or S-phase were exposed for 20 hours an dose (AD) 900 MHz RF at average specific absorption rate 1.25 W/kg and then treated with a challenge (CD) 100 ng/ml mitomycin C (MMC). Un-exposed sham-exposed controls as well cells MMC alone included study. The incidence micronuclei (MN) was evaluated determine induction AR.The...
The design and realization of a nanosecond, high-voltage electric pulse generator for bioelectrical applications is reported in this paper. A Blumlein type architecture was adopted, with some modifications, realized microstrip line configuration meander-shaped conducting strips, ultra-fast, high voltage solid state switches. Three microstrip-lines have been such way that, being interchangeable within the structure, they allow to match different load impedances. fiber optic-based system also...

RF exposure for 24 h at specific absorption rate (SAR) 10 W/kg was carried out in waveguide system under accurately controlled environmental and dosimetric parameters. DNA integrity, cell viability, apoptosis...
Populus x canadensis clone I-214 exhibits a general indicator phenotype in response to excess Zn, and higher metal uptake roots than shoots with reduced translocation aerial parts under hydroponic conditions. This physiological adaptation seems mainly regulated by roots, although the molecular mechanisms that underlie these processes are still poorly understood. Here, differential expression analysis using RNA-sequencing technology was used identify involved Zn root. In order maximize...
Abstract The last decades have seen increased interest toward possible adverse effects arising from exposure to intense static magnetic fields. This concern is mainly due the wider and applications of such fields in industry clinical practice; among them, Magnetic Resonance Imaging (MRI) facilities are main sources for both general public (patients) workers. In recent investigations, exposures been demonstrated elicit, different cell models, permanent transient modifications cellular...
This study aims to assess whether a 1950 MHz radiofrequency (RF) electromagnetic field could protect human neuroblastoma SH-SY5Y cells against subsequent treatment with menadione, chemical agent inducing DNA damage via reactive oxygen species formation. Cells were pre-exposed for 20 h specific absorption rate of either 0.3 or 1.25 W/kg, and 3 after the end exposure, they treated 10 µM menadione (MD) 1 h. No differences observed between sham- RF-exposed samples. A statistically significant...
In this study, the effect of radiofrequency (RF) exposure to 1950 MHz, Universal Mobile Telecommunication System signal, was investigated in Chinese hamster lung fibroblast cell line (V79). Genotoxic and cytotoxic effects 20‐h at specific absorption rate (SAR) values from 0.15 W/kg 1.25 were measured by means cytokinesis‐block micronucleus (MN) assay.
