Abstract
PURPOSE Earlier evidence suggests that extremely low frequency magnetic fields (ELF MFs) can modify the effects of carcinogenic agents. However, the studies conducted so far with ionizing radiation as the co-exposure agent are sparse and have provided inconclusive results. We investigated whether 50 Hz MFs alone, or in combination with ionizing radiation alter cell biological variables relevant to cancer and the biological effects of ionizing radiation. MATERIALS AND METHODS Human SH-SY5Y neuroblastoma cells were sham exposed or exposed to 100 or 500 µT MF for 24 h either before or after ionizing radiation exposure (0, 0.4 or 2 Gy). After the exposures, cells were assayed for viability, clonogenicity, reactive oxygen species, caspase-3 activity, and cell cycle distribution. Cell cycle distribution was assayed with propidium iodide staining followed by flow cytometry analysis and ROS levels were assayed together with cell viability by double staining with DeepRed and Sytox Blue followed by flow cytometry analysis. RESULTS Increased caspase-3 activity was observed in cells exposed to 500 µT MF before or after ionizing radiation. Furthermore, exposure to the 500 µT MF after the ionizing radiation decreased the percentage of cells in S-phase. No changes in the ROS levels, clonogenicity, or viability of the cells were observed in the MF exposed groups compared to the corresponding sham exposed groups, and no MF effects were observed in cells exposed at 100 µT. CONCLUSIONS Only the 500 µT magnetic flux density affected SH-SY5Y cells significantly. The effects were small but may nevertheless help to understand how MFs modify the effects of ionizing radiation. The increase in caspase-3 activity may not reflect effects on apoptosis, as no changes were observed in the subG1 phase of the cell cycle. In contrast to some earlier findings, 50 Hz MF exposure after ionizing radiation was not less effective than MF treatment given prior to ionizing radiation.

Abstract
INTRODUCTION Osteoarthritis is a musculoskeletal disease that can lead to the loss and inability of those affected to perform normal daily functions, which leads to a decrease in quality of life. The main symptoms of osteoarthritis are tenderness, joint pain, stiffness, crepitus, limited movement, and local inflammation. AREAS COVERED The selected patents were deposited from 2010 to April 2022 involving 57 documents that were in line with the study objective in the final selection. The patents were classified in years, country, and applicants. Also, the therapeutic fields that presented the most documents were electrical stimulation, phototherapy, and ultrasound, followed by magnetic, electromagnetic, and thermotherapy. Therefore, the most current therapies used in the documents are already on the market. EXPERT OPINION Although the OA is cureless, non-surgical treatments are classified as the primary management approach for this disease. The pharmacological and non-pharmacological therapies are employed to reduce its prevalence and ensure the effectiveness of treatments. A strategy for relieving OA symptoms is non-pharmacological treatment, which can be based on exercise and patient education, combined with other alternative therapies. These therapies are used as supplements to the main OA treatments, enhancing the effectiveness of treatment outcomes.

Abstract
Electromagnetic fields (EMF) are increasing in popularity as a safe and non-invasive therapy. On the one hand, it is widely acknowledged that EMF can regulate the proliferation and differentiation of stem cells, promoting the undifferentiated cells capable of osteogenesis, angiogenesis, and chondroblast differentiation to achieve bone repair purpose. On the other hand, EMF can inhibit tumor stem cells proliferation and promote apoptosis to suppress tumor growth. As an essential second messenger, intracellular calcium plays a role in regulating cell cycle, such as proliferation, differentiation and apoptosis. There is increasing evidence that the modulation of intracellular calcium ion by EMF leads to differential outcomes in different stem cells. This review summarizes the regulation of channels, transporters, and ion pumps by EMF-induced calcium oscillations. It furtherly discusses the role of molecules and pathways activated by EMF-dependent calcium oscillations in promoting bone and cartilage repair and inhibiting tumor stem cells growth.

Abstract
BACKGROUND The exposure of breast cancer to extremely low frequency magnetic fields (ELF-MFs) results in various biological responses. Some studies have suggested a possible cancer-enhancing effect, while others showed a possible therapeutic role. This study investigated the effects of in vitro exposure to 50 Hz ELF-MF for up to 24 h on the viability and cellular response of MDA-MB-231 and MCF-7 breast cancer cell lines and MCF-10A breast cell line. METHODS AND RESULTS The breast cell lines were exposed to 50 Hz ELF-MF at flux densities of 0.1 mT and 1.0 mT and were examined 96 h after the beginning of ELF-MF exposure. The duration of 50 Hz ELF-MF exposure influenced the cell viability and proliferation of both the tumor and nontumorigenic breast cell lines. In particular, short-term exposure (4-8 h, 0.1 mT and 1.0 mT) led to an increase in viability in breast cancer cells, while long and high exposure (24 h, 1.0 mT) led to a decrease in viability and proliferation in all cell lines. Cancer and normal breast cells exhibited different responses to ELF-MF. Mitochondrial membrane potential and reactive oxygen species (ROS) production were altered after ELF-MF exposure, suggesting that the mitochondria are a probable target of ELF-MF in breast cells. CONCLUSIONS The viability of breast cells in vitro is influenced by ELF-MF exposure at magnetic flux densities compatible with the limits for the general population and for workplace exposures. The effects are apparent after 96 h and are related to the ELF-MF exposure time.

Abstract
Gliomas refer to a group of complicated human brain tumors with a low 5-year survival rate and limited therapeutic options. Extremely low-frequency pulsed electromagnetic field (ELF-PEMF) is a specific magnetic field featuring almost no side effects. However, the application of ELF-PEMF in the treatment of gliomas is rare. This review summarizes five significant underlying mechanisms including calcium ions, autophagy, apoptosis, angiogenesis, and reactive oxygen species, and applications of ELF-PEMF in glioma treatment from a clinical practice perspective. In addition, the prospects of ELF-PEMF in combination with conventional therapy for the treatment of gliomas are reviewed. This review benefits any specialists, especially oncologists, interested in this new therapy because it can help treat patients with gliomas properly.

Abstract
By growing the electrical power networks and electronic devices, electromagnetic fields (EMF) have become an inseparable part of the modern world. Considering the inevitable exposure to a various range of EMFs, especially at extremely low frequencies (ELF-EMF), investigating the biological effects of ELF-EMFs on biological systems became a global issue. The possible adverse consequences of these exposures were studied, along with their potential therapeutic capabilities. Also, their biological impacts in combination with other chemical and physical agents, specifically ionizing radiation (IR), as a co-carcinogen or as adjuvant therapy in combination with radiotherapy were explored. Here, we review the results of several in-vitro and in-vivo studies and discuss some proposed possible mechanisms of ELF-EMFs' actions in combination with IR. The results of these experiments could be fruitful to develop more precise safety standards for environmental ELF-EMFs exposures. Furthermore, it could evaluate the therapeutic capacities of ELF-EMFs alone or as an improver of radiotherapy.

Abstract
UNLABELLED The high prevalence of breast cancer and the high complication rate of combined radical treatment make the issue of medical rehabilitation using physical factors in patients after surgery highly relevant and warrant the need to determine the contribution of individual factors. OBJECTIVE To compare the efficacy of general magnetic therapy and low-frequency electrostatic field on days 2-4 after the radical surgical treatment of breast cancer and 1.0-1.5 months after radiation therapy in combination with therapeutic physical training, motor-cognitive training, and sessions with a psychologist. MATERIALS AND METHODS Examination and medical rehabilitation of 131 patients after radical surgical treatment of breast cancer were performed. Age ranged from 30 to 75 years. Group 1 included 66 patients who received medical rehabilitation on days 2-4 after the surgery and 1.0-1.5 months later in addition to adjuvant radiotherapy; Group 2 included 65 patients who received medical rehabilitation only after 1.0-1.5 months in addition to adjuvant radiotherapy. RESULTS AND CONCLUSION It was shown that two courses of medical rehabilitation with the addition of physiotherapeutic treatment on days 2-4 and 1.0-1.5 months after radical breast cancer surgery in addition to radiation therapy contribute to a significant reduction of functional disorders severity in patients versus initiation of medical rehabilitation 1.0-1.5 months after the surgery in addition to radiation therapy. The feasibility of including general magnetic therapy procedures and low-frequency electrostatic field exposure in the medical rehabilitation course was demonstrated as it results in pain relief, postoperative edema reduction, and quicker recovery of the shoulder joint mobility that promotes long-term clinical benefit.

Abstract
OBJECTIVE Compare the efficacy of low-frequency low-intensity magnetotherapy and fluxtuorization of the shoulder belt and upper limb muscles on the side of surgical intervention in combination with therapeutic exercise and balance therapy, classes in a medical psychologist in patients for 2-4 days and 1.5-2 months after the radical mastectomy. MATERIAL AND METHODS A total of 131 patients aged 25 to 70 years were examined and treated after a radical mastectomy for breast cancer. The 1st group included 76 patients who were rehabilitated on the 2nd-4th day after radical mastectomy, the 2nd group included 55 women who were rehabilitated after 1.5-2 months. RESULTS AND CONCLUSION It has been established that the early onset of medical rehabilitation in patients after radical mastectomy (on the 2nd-4th day after surgical intervention) contributed to the reduction of pain syndrome and postoperative edema, increase of movements in shoulder joint, prevention of severe lymphostasis and improvement of life quality. The contribution of low-frequency low-intensity magnetotherapy to the complex of rehabilitation measures is, above all, to reduce swelling and reduce blood viscosity. Fluctuating currents promote restoration of volume of movements on the party of operative intervention, namely - support functional activity of muscles and joints of the top extremity that allows to restore a motor stereotype.
