Influences of discharge voltage on wheat seed vitality were investigated in a dielectric barrier discharge (DBD) plasma system at atmospheric pressure and temperature. Six different treatments were designed, and their discharge voltages were 0.0, 9.0, 11.0, 13.0, 15.0, and 17.0 kV, respectively. Fifty seeds were exposed to the DBD plasma atmosphere with an air flow rate of 1.5 L min(-1) for 4 min in each treatment, and then the DBD plasma-treated seeds were prepared for germination in several Petri dishes...

This study examined the effects of low frequency magnetic field (MF) on tolerance to analgesic effect of morphine in rats. Rats were made tolerant to morphine by injecting morphine (10 mg/kg, s) once daily for 8 consecutive days. Rats were simultaneously exposed to an MF (50 Hz at 1, 50, and 100 μT for 30 min) before, immediately, or 30 min after injection of morphine, and also exposed to a 0.5, 6, 12, and 30 Hz at 100 μT for 30 min before injection of morphine. The percentage of maximum possible effect of morphine (% MPE) was measured on the 1st, 4th, and 8th days by hot plate test...

Modulations of epigenetic machinery, namely DNA methylation pattern, histone modification, and non-coding RNAs expression, have been recently included among the key determinants contributing to Parkinson's Disease (PD) aetiopathogenesis and response to therapy. Along this line of reasoning, a set of experimental findings are highlighting the epigenetic-based response to electromagnetic (EM) therapies used to alleviate PD symptomatology, mainly Deep Brain Stimulation (DBS) and Transcranial Magnetic Stimulation (TMS)...

Chunxiao Xu, Yuxia Zhang, Yang Yu, Yue Li, Shufeng Wei
We previously found that flowering of Arabidopsis was suppressed by near-null magnetic field, which was related to cryptochrome. Auxin plays an important role in Arabidopsis flowering. To test whether auxin is involved in the suppression of Arabidopsis flowering by near-null magnetic field, we detected auxin level and expressions of auxin transport and signaling genes in wild-type Arabidopsis plants and cryptochrome double mutant, cry1/cry2, grown in near-null magnetic field. We found that indole-3-acetic acid (IAA) level in roots of wild-type plants in near-null magnetic field was significantly increased compared with the local geomagnetic field control, while IAA level in rosettes of 33-day-old wild-type plants in near-null magnetic field was significantly lower than the control...

Marta Fernandez, Hugo G Espinosa, David V Thiel, Amaia Arrinda
The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown to reduce these effects. The specific absorption rate is less than international health standards for most wearable antennas due to small transmitter power. This paper reports the linear relationship between power absorbed by biological tissues at different locations on the body and radiation efficiency based on numerical modeling (r = 0...

This study reports the effects of exposing cells of the prototypical enteropathogenic Escherichia coli (EPEC) strain E2348/69 to static magnetic fields (SMF) of varying intensities to observe their capacity to autoaggregate and the effect on cell adherence. The results showed that bacteria exposure over the course of 5 min to an intensity of 53 mT reduced autoaggregation by 28%. However, with intensities of up to 100 mT with the same exposure time, bacteria autoaggregation was reduced by approximately 50%; and after 30 min at the same intensity, it was indistinguishable from that observed in a non-autoaggregative strain...

This article considers the possibility of excitation of acoustic oscillations in a cell by electromagnetic waves. In this process, not only the frequency but also the length of a wave is of great importance. It is also reported that the pulse signal can be more effective than harmonic signal, and the pulse length is not essential. In accordance with this fact, it is possible to explain the biological effects of electromagnetic waves and to develop new medical electronic devices. Bioelectromagnetics. 2017;9999:XX-XX...

A half-space electromagnetic model of human skin over the band 30-300 GHz was constructed and used to model radiometric emissivity. The model showed that the radiometric emissivity rose from 0.4 to 0.8 over this band, with emission being localized to a layer approximately one millimeter deep in the skin. Simulations of skin with differing water contents associated with psoriasis, eczema, malignancy, and thermal burn wounds indicated radiometry could be used as a non-contact technique to detect and monitor these conditions...

Jie Tong, Lijun Sun, Bin Zhu, Yun Fan, Xingfeng Ma, Liyin Yu, Jianbao Zhang
Pulsed electromagnetic fields (PEMF) can be used to treat bone-related diseases, but the underlying mechanism remains unclear, especially the process by which PEMFs initiate biological effects. In this study, we demonstrated the effects of PEMF on proliferation and differentiation of osteoblasts using the model of calcium transients induced by high extracellular calcium. Our results showed that PEMF can increase both the percentage of responding cells and amplitude of intracellular calcium transients induced by high extracellular calcium stimulation...

Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U...

As an external physical factor, electromagnetic field (EMF) may influence cellular processes and nitric oxide (NO) by serving as a secondary messenger molecule in intracellular signaling cascades. Effects of these factors were evaluated simultaneously on viability, morphology, and variation of calcium ion content, and neural protein marker expression in rat bone marrow mesenchymal stem cells (BMSCs). The mesenchymal stem cells were isolated from rat bone marrow and cultured. Deta-NO as a donor molecule of NO was added to cell culture medium after several passages...

The biological effects of a (25) Mg nuclear spin and weak magnetic fields have been found and studied by using bacterial cells of Escherichia coli (E. coli) grown on standard M9 nutrient media with different isotopes of magnesium: (24) Mg, (25) Mg, (26) Mg, and a natural mixture of Mg isotopes. Among these isotopes only (25) Mg has a nuclear spin I = 5/2 and nuclear magnetic moment which have been known to affect enzymatic processes in vitro due to hyperfine interactions with uncoupled electrons of substrates...
