ABSTRACT Capacitive-Resistive Electric Transfer (CRET) thermotherapies aim at tissue repair and regeneration through non-invasive application of RF currents. We have reported that the cellular response to subthermal CRET currents is non-linearly dependent on the signal frequency, and that in vitro exposure to a 448-kHz CRET signal promotes ADSC proliferation, as well as collagen and glycosaminoglycan

ABSTRACT Among haematological parameters of patients seriously ill with the coronavirus infectious disease 2019 (COVID-19), leucocytosis, lymphocytopenia, and the abnormal release of circulating cytokines, termed cytokine storm syndrome (CSS, also known as cytokine release syndrome or CRS), were found associated with disease severity. In particular, according to the serum cytokine profiling, pro-inflammatory

ABSTRACT Plaques formed by abnormal accumulation of amyloid β-peptide (Aβ) lead to onset of Alzheimer’s disease (AD). Pharmacological treatments do not reduce Aβ aggregation neither restore learning and memory. Noninvasive techniques have emerged as an alternative to treat AD, such as stimulation with electromagnetic fields (EMF) that decrease Aβ deposition and reverses cognitive impairment in AD mice

ABSTRACT Low-frequency vibrational excitations of protein macromolecules in the terahertz frequency region are suggested to contribute to many biological processes such as enzymatic catalysis, intra-protein energy/charge transport, recognition, and allostery. To explain high effectiveness of these processes, two possible mechanisms of the long-lived excitation were proposed by H. Fröhlich and A.S.

ABSTRACT Research interest in ingestible Wireless Capsule Endoscopy (WCE) studies in humans showed better results than conventional invasive probe endoscopy methods. Because of the structure and the position of the small intestine, proper scanning cannot be done in the area using traditional endoscopic methods. For patient comfort, continuous developments have been suggested in capsule endoscopy designs

Weak combined collinear magnetic fields (CMFs) composed of constant component, 60 μT and low-frequency alternating field, 100 nT, used in 40 min pretreatment, were shown to have diverse effects (alleviation/stimulation) depending on the frequency of the alternating component on respiratory burst intensity in neutrophil suspension after activation by N-formyl-Met-Leu-Phe recorded by luminol-dependent

Thermal ablation (TA) is a therapeutic option for benign, non-functioning thyroid nodules causing symptoms of compression and/or aesthetic concerns. TA was initially introduced as a treatment for patients who refused or were ineligible for surgery. In more recent years, the increase in the positive experiences of TA have paved the way for the idea that TA could be suggested as a first-line treatment

The present study examines the histomorphometric and biochemical effects of PEMF application on

ABSTRACT Skin aging is primarily associated with the alterations in dermal extracellular matrix, in particular a decrease in collagen type-1 content. Recent studies have shown that collagen-degrading matrix metalloproteinase (MMP-1) is produced by fibroblasts in response to chronoaging, which in human dermal fibroblasts leads to the release of proinflammatory cytokines. Past studies showed that anti-inflammatory

For this reason, the aim of this study was to determine the efficacy of monopolar dielectric diathermy by emission of radiofrequency (MDR) in dynamic applications aimed at treating pain and improving function in patients with PFPS. For this purpose

Hallux valgus (HV) is a foot deformity with deviation of the greater toe and the first metatarsal. There is little evidence on training the abductor hallucis muscle (AbdH) to treat HV because of the difficulty in implementing the necessary interventions. Although neuromuscular electrical stimulation (NMES) has been used to induce voluntary exercise, there is currently no study on NMES for AbdH. We

Therefore, we aimed to suggest hypotheses about the complex mechanisms of headaches related to HF-exposure. We crossed basic features of headaches with relevant studies (from the year 2000 up to 2018) emphasizing

Twenty young (2-3-month-old) female mice, 20 adult (9-10-month-old) female mice and 12 aged (14-15-month-old) female mice were divided into two groups (control and rTMS treatment). rTMS-treated groups were

People are increasingly exposed to electromagnetic radiation with the rapid development of technologies such as broadcasting and mobile communication system. There is a concern that long-term exposure at low levels may be associated with various non-specific physical symptoms and ecological effects on animals and plants. It is extremely important to measure and analyze the electromagnetic radiation

DNA repair is essential to maintain genome integrity. There is scientific evidence that exposure to magnetic fields (MF) can produce alterations in DNA repair without clear conclusions. This work aims to study the cellular response to and repair of a very deleterious type of DNA damage, the DNA double strand break (DSB), in S. cerevisiae, under MF exposure. In S. cerevisiae cells, pairs of DSB were

The rats exposed for 10 sec every 50 sec to a field

Recent data show that microwaves (MW) and extremely low-frequency (ELF) magnetic fields at low intensities affect conformation of nucleoids in bacterial E. coli cells and human lymphocytes. Experimental data suggest that magnitude of the effects of both MW and ELF depend on frequency and static magnetic field. We have previously proposed the physical model for the effects of combined ELF/static magnetic
