Effect of extremely low frequency electromagnetic field parameters on the proliferation of human breast cancer
Electromagn Biol Med. 2021 Feb 25:1-9. doi: 10.1080/15368378.2021.1891093. Online ahead of print.ABSTRACTExtremely low-frequency electromagnetic field (ELF-EMF) exposures influence many biological systems. These effects are mainly related to the intensity, duration, frequency, and pattern of the ELF-EMF. Our intent was to characterize the effect of specific pulsed electromagnetic fields on the in vitro proliferation of MCF-7 adenocarcinoma and MDA-MB-231 breast cancer cell lines and one non-cancerous M10 breast epithelial cell line. The following four important parameters of ELF-EMF were examined: frequencies (7.83 ±...

An Evaluation of the Genotoxic Effects of Electromagnetic Radiation at 900 MHz, 1800 MHz, and 2100 MHz Frequencies with a SMART Assay in < em > Drosophila melanogaster < /em >
In this study, the genotoxic effects of radiofrequency electromagnetic radiation were evaluated by the wing Somatic Mutation and Recombination Test (SMART) in Drosophila melanogaster at 900 MHz, 1800 MHz, and 2100 MHz. The SMART method is based on the observation of genetic changes occurring in the trichomes of the Drosophila wings appearing as mutant clones under the microscope. Throughout the study, total clone parameters were evaluated by exposing the Drosophila larvae to electromagnetic fields for two, four, and six hours per day for two days. As a result of the study, it was observed that the number of mutant clones w...

The 4Hz mechanical vibration-activated Na/Ca exchange as a quantum-sensitive novel target for pain therapy.
Authors: Madoyan G, Azizyan A, Musheghyan G, Ayrapetyan S Abstract The activation of Na/40Ca exchange in reverse (R) mode leading to neuronal swelling and muscle contraction has been suggested as a mechanism for generation of pain signals. However, the activation of R Na/45Ca exchange, having higher rate than R Na/40Ca exchange, brings to depression of pain sensation, the mechanism of which is not clear. The previous data that the 4 Hz mechanical vibration (MV) has pain-relieving effects by activation of cGMP-dependent Na/Ca exchange in forward (F) mode, which leads to muscle hydration and neuronal dehydration...

Association between reproductive health and nonionizing radiation exposure.
Authors: Negi P, Singh R Abstract Recently, a decreasing rate of fertility has to be credited to an array of factors such as environmental, health and lifestyle. Male infertility is likely to be affected by the strong exposure to heat and radiations. The most common sources of nonionizing radiations are cell phones, laptops, Wi-Fi and microwave ovens, which may participate to the cause of male infertility. One of the major sources of daily exposure to non-ionizing radiation is mobile phones. A mobile phone is now basically dominating our daily life through better services such as connectivity, smartphone devices. H...

Inhibition of B16F10 Cancer Cell Growth by Exposure to the Square Wave with 7.83+/-0.3Hz Involves L- and T-Type Calcium Channels.
In this study, exposure to square wave with 7.83±0.3 Hz (sweep step 0.1 Hz) was shown to inhibit the growth of B16F10 melanoma tumor cells.

Authors: Srivastava Y, Sassaroli E, Swain J, Widom A, Narain M, de Montmollin G Abstract All therapeutic methods dealing with coronavirus (past and present) are based on chemicals. We test for it (positive or negative) chemically and hope to cure it with a future vaccine (some complicated chemical preparation). If and when the virus mutates, another set of chemical protocols for its testing and a hunt for new chemicals as a vaccine shall begin again and again. But the history of modern (western) medicine tells us that our biotechnology is not so limited. Copious scientific evidence for sonic and low energy electrom...

Low-frequency electromagnetic fields promote hair follicles regeneration by injection a mixture of epidermal stem cells and dermal papilla cells.
Authors: Li X, Ye Y, Liu X, Bai L, Zhao P, Bai W, Zhang M Abstract The bioeffects of low-frequency electromagnetic fields (EMF) on a bio-engineered hair follicle generation had not been fully elucidated. This present study was designed to evaluat the therapeutically effective of low frequency EMF on hair follicles regeneration. In this experiment, epidermal stem cells (ESCs) and dermal papilla (DP) cells were isolated and culture-expanded. Then the mixture containing of ESCs and DP cells was implanted into the epidermal layer or corium layer of nude mice. Those mice were  divided at random into the control gro...
