ABSTRACT In this paper, we present the design, RF-EMF performance, and a comprehensive uncertainty analysis of the reverberation chamber (RC) exposure systems that have been developed for the use of researchers at the University of Wollongong Bioelectromagnetics Laboratory, Australia, for the purpose of investigating the biological effects of RF-EMF in rodents. Initial studies, at 1950 MHz, […]

ABSTRACT The widespread use of wireless communication technologies has increased human exposure to radiofrequency electromagnetic fields (RF-EMFs). Considering the brain’s close proximity to mobile phones and its entirely electrical transmission network, it emerges as the organ most profoundly impacted by the RF field. This study aims to investigate the potential effects of RF radiation on […]

ABSTRACT Temporal interference stimulation (TIS) is a new form of transcranial electrical stimulation (tES) that has been proposed as a method for targeted, noninvasive stimulation of deep brain structures. While TIS holds promise for a variety of clinical and nonclinical applications, little data is yet available regarding its effects in humans and its mechanisms of […]

ABSTRACT Although static magnetic fields (SMFs) have been reported to induce only minimal biological effects, it has been proposed that they may alter the effects of other agents, such as ionizing radiation. We sham-exposed or exposed human SH-SY5Y neuroblastoma cells to 0.5-, 1.5-, 2.5-, or 3.5-mT SMFs for 24 h either before or after irradiation at […]

ABSTRACT Readily available animal tissue, such as ground beef, is a convenient material to represent the dielectric properties of biological tissue when validating microwave imaging and sensing hardware and techniques. The reliable use of these materials depends on the accurate characterization of their properties. In this work, the effect of physiologically relevant levels of dehydration […]

ABSTRACT Electrical stimulation of peripheral nerves via implanted electrodes has been shown to be a promising approach to restore sensation, movement, and autonomic functions across a wide range of illnesses and injuries. While in principle computational models of neuromodulation can allow the exploration of large parameter spaces and the automatic optimization of stimulation devices and […]

Abstract Our study focused on investigating the bioeffects of extremely low-frequency electromagnetic fields (ELF-EMFs) on the immune function of the spleen. We designed an electromagnetic instrument that can locally target on spleen, the spleens of mice were locally exposed to the ELF-EMF (50 Hz, 30 mT) for 14 days (4 h/day). Parallelly, the isolated splenic T cells were […]

Abstract Effects of non-uniform upward (north) and downward (south) 300 mT static magnetic field (SMF) 14 days (24 h/day) treatment of Platycodon grandiflorum seeds on germination, seedling growth, enzyme activities, malondialdehyde (MDA) level and seedling chlorophyll content were investigated under laboratory conditions. Germination rate, index and potential from magnetically exposed Anhui and Hebei Platycodon grandiflorum seeds […]

Abstract The rapid growth of mobile phone usage and its use of radiofrequency electromagnetic fields (RF-EMF) have raised concerns about potential health risks. Researchers have conducted studies to examine the effects of RF-EMF on the brain using electroencephalography (EEG). We conducted a systematic quality assessment and meta-analysis of published research in this field to establish […]
