Collective phenomena in strongly nonequilibrium systems interacting with electromagnetic field are considered. Such systems are described by complicated non-linear differential or integro–differential equations. The aim of this review is to show that many nonlinear collective phenomena can be successfully treated by a recently developed method called the Scale Separation Approach whose name is ...
objective(s):electromagnetic radiations which have lethal effects on the living cells are currently also considered as a disinfective physical agent. materials and methods: in this investigation, silver nanoparticles were applied to enhance the lethal action of low powers (100 and 180 w) of 2450 mhz electromagnetic radiation especially against escherichia coli atcc 8739. silver nanoparticles ...
objective: most people experience bone damage and bone disorders during their lifetimes. the use of autografts is a suitable way for injury recovery and healing. mesenchymal stem cells (mscs) are key players in tissue engineering and regenerative medicine. their proliferation potential and multipotent differentiation ability enable mscs to be considered as appropriate cells for therapy and clin...
Background and Objective: Diabetes influences the normal function of the pituitary-thyroid axis. According to the antidiabetic and antioxidant effects of curcumin and the different effects of electromagnetic fields on animal cells, this study was done to evaluate the effect of curcumin and weak low frequency electromagnetic fields on thyroid hormone serum levels in male diabetic rats. Materi...
Background and purpose: Angiogenesis has a role in many vital processes also many developmental processes are influenced by an electromagnetic field. In the present study the synergic effects of silver nanoparticles and low-frequency electromagnetic field on angiogenesis in the chick embryo chorioallantoic membrane (CAM). Materials and method: In this experimental study, (Ross strain )...
This paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. When a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...
Introduction: Today the rate of human beings exposed to electromagnetic fields is increasing deliriously and human beings are being more drowned in the ocean of electromagnetic fields each day. It has been a long time that the effects of electromagnetic fields on organisms has been studied by researchers and due to the long-term researches and the slow impact of fields on life-cycle processes, ...
background : effects of electromagnetic fields on healing have been investigated for centuries. substantial data indicates that exposure to electromagnetic field can lead to enhanced healing in both soft and hard tissues. helmholtz coil is a device that generates pulsed electromagnetic fields. objective : in this study, a pair of helmholtz coils for enhancing the healing process in periodontiti...
Purpose: Increasing use of electromagnetic waves in living medium, industry, communication and medicine, strongly requires multiporposal evaluation of the effects of electromagnetic fields (EMF), with different frequencies, on body tissues and organs.Contrauersal reports on detrimental effects of EMF on biological systems influenced us to carry out this study. Materials and Methods: In order t...
Background & Aims : Breast cancer is the most common cancer in women. The aim of this study was to investigate the effects of electromagnetic field on MCF-7 cancer cell line . Materials & Methods : MCF-7 cell lines and L929 cell line were cultured in RPMI medium that contain fetal bovine serum and antibiotics . Cells for three hours were exposed to 50 Hz electromagnetic field with intensi...
