Plant Responses to High Frequency Electromagnetic Fields
High frequency nonionizing electromagnetic fields (HF-EMF) that are increasingly present in the environment constitute a genuine environmental stimulus able to evoke specific responses in plants that share many similarities with those observed after a stressful treatment. Plants constitute an outstanding model to study such interactions since their architecture (high surface area to volume rati...
متن کاملMethods of health risk assessment for human exposure to high frequency electromagnetic fields
The paper reviews some topics in human exposure to high frequency (HF) electromagnetic fields based on certain integral equation formulations and related numerical solution procedures. Illustrative computational examples are related to the human eye and the human brain exposed to HF radiation. The obtained numerical results for specific absorption rate (SAR) are compared against exposure limits...
متن کاملEffect of occupational exposure to extremely low frequency electromagnetic fields on level of thyroid hormones effective on fatigue
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
متن کاملEffect of high-frequency electromagnetic fields on trophoblastic connexins.
Connexins (Cx) are membrane proteins able to influence trophoblast functions. Here we investigated the effect of high-frequency electromagnetic fields (HF-EMF) on Cx expression and localization in extravillous trophoblast cell line HTR-8/SVneo. We also analysed cell ultrastructural changes induced by HF-EMF exposure. Samples were exposed to pulse-modulated 1817 MHz sinusoidal waves (GSM-217 Hz;...
متن کاملHigh Frequency Magnetic Fields in Treatment of Osgood-Schlatter Disease
We are studied efficacy of high frequency magnetic fields (HFMFs) in treatment of Osgood-Schlatter disease (OSD) including X-rays signs. THELF system apparatus has been used for treatments on 32 young sportsmen (9-15 years). 18 boys and 14 girls, with HFMFs (base frequency 27.125 MHz, with different impulse repetition frequency of 640 Hz and 320 Hz, and absorbed power 3-5 VA). Injured sportsmen...
