“…In [9] Szyjkowska et al confirmed that work-related stress is strongly correlated with the heart rate and blood pressure; work-related stress in men was usually in association with higher blood pressure, whereas more prominent heart rate variability was usually observed in women. Moreover, stress also affects cognitive abilities; people suffering from stress make more mistakes and perform tasks less accurately [1].…”

“…Among many different physiological stress indicators, such as blood pressure, cortisol level, increased skin conductivity, and head and body movements, HRV is considered one of the reliable methods for assessing the physiological response of the body in response to stress. HRV is caused by the interaction of the sympathetic and parasympathetic parts of the autonomic nervous system and can be analyzed in time and frequency domains [6][7][8][9][10][11].…”

Stress is a physical, mental, or emotional response to a change and is a significant problem in modern society. In addition to questionnaires, levels of stress may be assessed by monitoring physiological signals, such as via photoplethysmogram (PPG), electroencephalogram (EEG), electrocardiogram (ECG), electrodermal activity (EDA), facial expressions, and head and body movements. In our study, we attempted to find the relationship between the perceived stress level and physiological signals, such as heart rate (HR), head movements, and electrooculographic (EOG) signals. The perceived stress level was acquired by self-assessment questionnaires in which the participants marked their stress level before, during, and after performing a task. The heart rate was acquired with a finger pulse oximeter and the head movements (linear acceleration and angular velocity) and electrooculographic signals were recorded with JINS MEME ES_R smart glasses (JINS Holdings, Inc., Tokyo, Japan). We observed significant differences between the perceived stress level, heart rate, the power of linear acceleration, angular velocity, and EOG signals before performing the task and during the task. However, except for HR, these signals were poorly correlated with the perceived stress level acquired during the task.

“…Длительность разговора с использованием мобильных телефонов также отражается на состоянии сердечно-сосудистой системы. В экспериментальном исследовании A. Szyjkowska et al [14] показано, что общение человека по мобильному телефону более 60 мин в сутки существенным образом сказывается на показателях артериального давления и достоверно (p = 0,04) отличается от показателей, полученных у людей, пользующихся телефоном менее часа в день. Выявленные нами корреляционные связи показателей первичной заболеваемости болезнями, характеризующимися повышенным кровяным давлением, и СЭЭ подтверждают эти данные.…”

Our research goal was to examine energy and time parameters of electromagnetic environment created by mobile communication terminals in Crimea and to detect a relationship between morbidity with diseases of the circulatory system (DCS) among people living in the republic due to electromagnetic environment. Electromagnetic environment was determined as per energy flux density (EFD) at terminals, average daily electro- magnetic exposure (ADEE) and individual electromagnetic burden (IEB). Correlation analysis of all the obtained data was performed to detect possible correlations with diseases of the circulatory system. Measurements of electromagnetic environment created by terminals in the region during a period from March 2019 to February 2020 (4,204 measurements at points where people used mobile communications intensely) yielded the following results: average EFD value amounted to 1.43 ± 0.04 µWt/cm2; IEB, 117.80 ± 6.55 (µWt/cm 2)·min; ADEE, 60.56 ± 1.15 min. Electromagnetic environment parameters and prevalence of the most common DCS in Crimea were statistically proc- essed and the following authentic correlations were revealed: between overall morbidity with circulatory diseases and en- ergy (EFD (Тau=0.399; p < 0.01)) and integral (IEB (Тau=0.437; p < 0.01)) properties of electromagnetic radiation; be- tween overall morbidity with diseases that involved elevated blood pressure and IEB (Тau=0.377, p=0.01); between primary morbidity with diseases that involved elevated blood pressure and all electromagnetic radiation properties: EFD (Тau=0.304, p=0.04), IEB (Тau=0.342, p=0.02), and ADEE (Тau=0.299, p=0.04); between primary morbidity with cere- brovascular diseases (CVD) and ADEE (Тau=0.411, p < 0.01) as time property of the examined factor. Energy and time parameters of electromagnetic environment created by mobile communication terminals that have been measured in Crimea are authentically correlated with distribution of morbidity with circulatory diseases and exert their influence on a risk of probable growth in morbidity with these nosologies among people living in Crimea.

Establishment of injury models in studies of biological effects induced by microwave radiation

2021

View full text Add to dashboard Cite

Microwave radiation has been widely used in various fields, such as communication, industry, medical treatment, and military applications. Microwave radiation may cause injuries to both the structures and functions of various organs, such as the brain, heart, reproductive organs, and endocrine organs, which endanger human health. Therefore, it is both theoretically and clinically important to conduct studies on the biological effects induced by microwave radiation. The successful establishment of injury models is of great importance to the reliability and reproducibility of these studies. In this article, we review the microwave exposure conditions, subjects used to establish injury models, the methods used for the assessment of the injuries, and the indicators implemented to evaluate the success of injury model establishment in studies on biological effects induced by microwave radiation.
