“…When using a mobile phone, a close distance between the phone and the breasts exists, and the breasts are exposed to significant amounts of radiofrequency radiation, which contributes to DNA damage and promotes the development of breast cancer ( 3 ). In addition, it has been reported that melatonin is a hydroxyl radical scavenger, and decreased expression of melatonin has been indicated to enhance the oxidative damage and increase breast cancer risk ( 52 ). Chang et al ( 53 ), conducted a randomized controlled trial to estimate the effect of iPad notebooks on melatonin expression.…”

The present systematic review and meta-analysis investigated the association between exposure to radiofrequency radiation and the risk of breast cancer. The published studies that were available in PubMed, Embase, Cochrane Library, Ovid MEDLINE, CINAHL Plus, Web of Science, Airiti Library, Networked Digital Library of Theses and Dissertations and ProQuest until May 2020 were investigated. A total of eight studies (four case-control and four cohort studies) were eligible for quantitative analysis. A significant association between radiofrequency radiation exposure and breast cancer risk was detected [pooled relative risk (RR)=1.189; 95% confidence interval (CI), 1.056-1.339]. Subgroup analyses indicated that radiofrequency radiation exposure significantly increased the risk of breast cancer susceptibility among subjects aged ≥50 years (RR=2.179; 95% CI, 1.260-3.770). Pooled estimates revealed that the use of electrical appliances, which emit radiofrequency radiation, such as mobile phones and computers, significantly increased breast cancer development (RR=2.057; 95% CI, 1.272-3.327), while occupational radiofrequency exposure and transmitters did not increase breast cancer development (RR=1.274; 95% CI, 0.956-1.697; RR=1.133; 95% CI, 0.987-1.300, respectively). It was concluded that radiofrequency radiation exposure significantly increased the risk of breast cancer, especially in women aged ≥50 years and in individuals who used electric appliances, such as mobile phones and computers. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis, an evaluation protocol was prepared and registered with the PROSPERO database (registration no. CRD42018087283).

“…Therefore, the radiofrequency emitted by mobile phones or electronic devices can induce both DNA damage and the suppression of melatonin expression. Suppression of the production of melatonin may cause an increased production of estrogen, resulting in a subsequent increase in the risk of breast cancer ( 25 , 52 , 53 ).…”

“…Furthermore, some occupational groups such as power plant workers are exposed to high levels of ELF‐EMFs caused by power transmission lines compared to the general public, which is a matter of concern 1,2 . Exposure to electromagnetic fields affect brain function, hormones, and enzymatic activity, and its effect depends on the frequency and duration of exposure 3,4 . Several potential reactive mechanisms such as oscillatory resonance, and the mediating mechanism of reactive oxygen species (ROS) that induce bipolar momentum may explain the mechanism of action of these fields, 5‐7 among which, the radical pair mechanism has been more widely accepted 8 .…”

Objectives This study was designed to investigate the possible effect of exposure to extremely low frequency electromagnetic fields (ELF‐EMFs) on occupational burnout syndrome and the severity of depression experienced among thermal power plant workers and the role of oxidative stress. Methods In this cross‐sectional study, 115 power plant workers and 124 administrative personnel of a hospital were enrolled as exposed and unexposed groups, respectively, based on inclusion and exclusion criteria. Levels of oxidative stress biomarkers, including malondialdehyde (MDA), superoxide dismutase (SOD), catalase (Cat), and total antioxidant capacity were measured in serum samples. Exposure to electric and magnetic fields was measured using the IEEE Std C95.3.1 standard at each workstation. The burnout syndrome and the severity of depression were assessed using the Maslach Burnout and Beck Depression Inventory. Results The levels of MDA and SOD were significantly lower in the exposed group than the unexposed group. The exposed group reported a higher prevalence of burnout syndrome and higher depression severity. Multiple linear regression showed that work experience, MDA level, and levels of exposure to magnetic fields are the most important predictor variables for burnout syndrome and severity of depression. In addition, a decrease in the level of Cat was significantly associated with increased burnout syndrome. Conclusion The thermal power plant workers exposed to ELF‐EMFs are at risk of burnout syndrome and depression. These effects may be caused directly by exposure to magnetic fields or indirectly due to increased oxidative stress indices.

“…The most sensitive tissues and organs of mammals under such conditions are the nervous system and blood, as well as the heart and the liver (Khnychenko & Sapronov, 2003;Volkova & Meleshkina, 2008;Sawa et al, 2017). Computerization of workplaces, which has led to the inactive condition of employees during the working day and an increase in the time spent by both children and adults sitting at the computer is a stressful load that worsens health (Warille et al, 2017). The chronic stage of stress conditions leads to a decrease in blood circulation due to vasoconstriction and an increase in the risk of developing hypoxic conditions in many organs and the nervous system (Ushakova et al, 2010;Tkachenko et al, 2018).…”

This article presents the results of the combined effect of water-immobilization and emotional stress on haematological and morphological parameters of blood and liver status of rats in conditions of correction of the disorders using by α-ketoglutarate. Experimental combined stress was induced by the interchangeable effect of dry immobilization and immersion in water for 3 days under constant illumination using an artificial lighting lamp of 1,000 lux., thus achieving a combined effect of stress. Physiological adaptation and administration of 5 mg/kg of body weight of α-ketoglutarate lasted 14 days after stress induction. Haematological parameters were determined using the Automated Veterinary Hematology Analyzer PCE 90 Vet (High Technology Inc., USA), while biochemical parameters of the liver state were determined by spectrophotometric and colourimetric methods. The obtained results showed an increase in hemolysis, which was determined by a decrease in the number of erythrocytes and haemoglobin concentration in the blood of rats under the effect of the stress factors studied. A negative consequence of strengthening of hemolysis is the development of hypoxia in the liver, which causes the slowing of metabolic processes in its cells. As a result, there is an accumulation of partially oxidized products: lactate and pyruvate, increased formation of TBA-active products, and oxidative modification of proteins. During the 14 days of physiological adaptation after stress, the main indicators of blood and liver status of the rats were partially restored. A stronger recovery of redox status and improvement of the physiological state of the liver and, hence, haematological parameters, were noted for rats that received α-ketoglutarate for 14 days after stress. The revealed general positive trend indicates the stimulation of adaptation processes and the overall functioning of the antioxidant system of the liver of rats in the use of α-ketoglutarate against the background of the combined effects of water-immobilization and emotional stress.
