Effect of electromagnetic field on whole blood, biochemical and hormone level in human

The electromagnetic field is increasing in our environment and these exposures cause concern. The aim of our study is to investigate the effects of magnetic fields generated by the hairdryer devices used by women working in the same job on their serum biochemistry, whole blood, and hormone values. The sixteen women working continuously in hairdressing salons were included in the study. Two groups of studies were designed: control (n:8, mean age: 22.25±6.04) and experimental group (n:8, mean age:23,62±6.67). The biochemical (median values of alanine aminotransferase, aspartate aminotransferase, triglycerides, and very-low-density lipoprotein were found high) and hormonal results of the experimental group were compared with the biochemical (cholesterol, low-density lipoprotein, and very high-density lipoprotein had high median values) and hormonal results of the control group and no significant difference was found (p>0.05). When the whole blood parameters were examined, the white blood cells and mean platelet volume results of the experimental group were significant (p<0.05), while there was a meaningless difference between red blood cell, hemoglobin, hematocrit, mean corpuscular volume, red cell distribution width and platelet values (p>0.05). It is evident from the results that occupational exposure to magnetic fields constantly leads to changes in the biochemistry, hormone and whole blood parameters of the female

Effects of Extremely Low Frequency Magnetic Field on the Lens of the Rats

The present aim of the study is to evaluate the effects of extremely low frequency magnetic field (ELF MF) on lens epithelial cells. Twenty adult female Spraque Dawley rats were divided into two groups, each containing 10 rats. The experimental group received magnetic field 2 hours/day for 7 days. The second group receiving standard laboratory care, was used as a control. The specimens were evaluated for cataractogenesis alteretion of lens and histological changes in lens epithelial cells.On biomicroscopic examination, no pathological damage to the lens was detected. In addition, on microscopic examination of materials in the controls, there were also no changes in lens fibrils and lens epithelial cells. In experimental group, however, only a slight pleomorphism was determined at the surface of epithelial cells.In the study, it is cocluded that ELF MF exposure do might not lead to histopathological alterations of the lens fibrils and lens epithelial cells

The Effect of Extremely Low Frequency Magnetic Field and Manganese on Bone Mineral Content and Density

The aim of this study was to investigate the effect of extremely low frequency magnetic field (ELF MF) on bone that exposed us in our daily life. In our study, sixty four male Wistar-Albino rats were used. The rats were exposed to ELF MF (50Hz, 1.5mT) during 4 hours/day for 45 days. The experimental rats were divided into eight groups (n=8 per group). The groups were as follows; only ELF MF was exposed to 1.group, the ELF MF was exposed to the 2., 3. and 4.groups with the doses manganese (Mn) of 3.75 mg/kg, 15mg/kg and 60mg/kg respectively, the 5., 6. and 7.groups received Mn with the doses of 3.75 mg/kg, 15mg/kg and 60mg/kg respectively and lastly the 8.group was used as a control group (cage control). Total bone mineral content (TBMC) and total bone mineral density (TBMD) of rats were determined by dual-energy X-ray absorptiometry (DXA). Measurements were recorded for all groups and the levels were compared with the control group. The levels of TBMC increased significantly in 3., 4. and 7. groups compare to control group (p<0.05). However, significant differences was not found in relation to the levels of TBMD between groups. The following results could be derived for this study; i) an additive effect of EMF was observed in increasing of bone mineral content for the groups with manganese ii) EMF stimulates the increasing of TBMD iii) manganese has a positive effect on bone tissue

Classification of Mental Task EEG Records Using Hjorth Parameters

25th Signal Processing and Communications Applications Conference (SIU) -- MAY 15-18, 2017 -- Antalya, TURKEYWOS: 000413813100471The effects of mental activities on brain dynamics is the main field that studied for a long time, but the results of studies have not reached the desired level. The aim of present study was to classify the mental task EEG records by using Hjorth parameters. hi this study, EEG signals that recorded from 9 subjects were used. EEG signals were recorded by applying a experimental paradigm which contains five stimuli related to different mental task. These stimuli are defined as condition word mental subtraction spatial navigation right hand motor imagery and feet motor imagery Wavelet packet transform was used to obtain sub bands of EEC signals. Statistical parameters that consist of mobility, complexity and Mahalanobis distance were applied to sub-bands. Feature vectors were classified by using artificial neural network. When classification performances related to mental activities were examined, the best classification accuracy was obtained as nearly 80% for 'condition word - mental subtraction', ('spatial navigation feet motor imagery;' and 'spatial navigation - condition word'. The lowest classification accuracy was obtained for 'mental subtraction - right hand motor imagery,', 'condition word - right hand motor imagery' and 'spatial navigation right hand motor imagery'. The classification accuracies related to all stimuli that classifed among themselves were obtained as 77,61%.Turk Telekom, Arcelik A S, Aselsan, ARGENIT, HAVELSAN, NETAS, Adresgezgini, IEEE Turkey Sect, AVCR Informat Technologies, Cisco, i2i Syst, Integrated Syst & Syst Design, ENOVAS, FiGES Engn, MS Spektral, Istanbul Teknik Uni

Interstitial space between cells in the left and right lobes of rat brains exposed to 900, 1800 and 2100 MHz radiofrequency radiation

AbstractThe head is the body part that is most exposed to radiofrequency radiation (RFR) during a mobile phone conversation. Therefore, it can be expected that brain cells will be positively or negatively affected by this physical agent. The purpose of this study was to investigate the effects of 900, 1800 and 2100 MHz on the interstitial space between cells in the right and left lobes of the brain. The study was carried out on 28 Wistar Albino rats, which were divided randomly into four groups (n: 7): sham control, 900 MHz, 1800 MHz and 2100 MHz exposure groups. The rats in the exposure groups were subjected to RFR for 3 h/day for one month. At the end of the last exposure, brains were immediately removed and prepared for electron microscopic examination. We determined the interstitial space (µm) between brain cells in the left and right lobes separately and compared them statistically. The results indicated that all three frequencies used in this study increased the interstitial space between cells in both brain lobes. The maximum effective frequencies were 1800 MHz for the right lobe and 2100 MHz for the left lobe. In conclusion, we observed that the RFR used in this study enhanced the interstitial space between cells in both lobes of the brain. Further studies are needed to confirm the results of this study, which we think will open different horizons

Classification of Epilepsy Types from Electroencephalogram Time Series Using Continuous Wavelet Transform Scalogram-Based Convolutional Neural Network

During the supervisory activities of the brain, the electrical activities of nerve cell clusters produce oscillations. These complex biopotential oscillations are called electroencephalogram (EEG) signals. Certain diseases, such as epilepsy, can be detected by measuring these signals. Epilepsy is a disease that manifests itself as seizures. These seizures manifest themselves in different characteristics. These different characteristics divide epilepsy seizure types into two main groups: generalized and partial epilepsy. This study aimed to classify different types of epilepsy from EEG signals. For this purpose, a scalogram-based, deep learning approach has been developed. The utilized classification process had the following main steps: the scalogram images were obtained by using the continuous wavelet transform (CWT) method. So, a one-dimension EEG time series was converted to a two-dimensional time-frequency data set in order to extract more features. Then, the increased dimension data set (CWT scalogram images) was applied to the convolutional neural network (CNN) as input patterns for classifying the images. The EEG signals were taken from Dicle University, Neurology Clinic of Medical School. This data consisted of four classes: healthy brain waves, generalized preseizure, generalized seizure, and partial epilepsy brain waves. With the proposed method, the average accuracy performance of three of the EEG records' classes (healthy, generalized preseizure, and generalized seizure), and that of all four classes of EEG records were 90.16 % (± 0.20) and 84.66 % (± 0.48). According to these results, regarding the specific accuracy ratings of the recordings, the healthy EEG records scored 91.29 %, generalized epileptic seizure records were at 96.50 %, partial seizure EEG records scored 89.63 %, and the preseizure EEG records had a 90.44 % rating. The results of the proposed method were compared to the results of both similar studies and conventional methods. As a result, the performance of the proposed method was found to be acceptable

Effect of a 50-Hz Sinusoidal Electromagnetic Field on the Integrity of Experimental Colonic Anastomoses Covered with Fibrin Glue

Kale, Ebru/0000-0002-1194-6649; H, Ozturk/0000-0001-5608-5742; Akpolat, Veysi/0000-0002-2435-7800WOS: 000270038600002Background. Low-frequency magnetic fields have been shown to affect biological processes. In this article the effects of 50-Hz sinusoidal magnetic field (MF) stimulation and application of fibrin glue on the healing of experimental colonic anastomoses were investigated. Material and Methods. Twenty-eight rats were divided into four groups. Group 1 underwent 2-cm left colonic resection and primary anastomosis. Group 2 underwent normal resection anastomosis and the area was covered with fibrin glue. Group 3 underwent normal resection anastomosis and the rats were exposed to a 50-Hz sinusoidal MF. Group 4 underwent normal resection anastomosis, the anastomosis area was covered with fibrin glue, and the rats were exposed to a 50-Hz sinusoidal MF. Investigations included bursting pressure measurement, hydroxyproline content, and histopathological changes. Results. Tissue hydroxyproline levels and anastomotic bursting pressures of groups 2, 3, and 4 were significantly higher than in group 1. Collagen deposition and fibroblast infiltration in groups 2, 3, and 4 had higher scores than in group 1. Furthermore, these results were significantly higher in group 4 rats than in the other groups. Histopathological examination of the anastomosis revealed significantly better healing patterns for group 4 than for groups 1, 2, and 3. Conclusions. A50-Hz sinusoidal MF stimulation and application of fibrin glue provided a significant gain in anastomotic healing in the large intestine. A combination of a 50-Hz sinusoidal MF and fibrin glue has significantly favorable effects on healing of experimental colon anastomosis (Adv Clin Exp Med 2009, 18, 1, 13-18)
