Oxidative stress refers to an imbalance between oxidants and antioxidants in vivo and is characterized by a biochemical state that tends toward oxidization, including the formation of oxygen free radicals (i.e., ROS) and nitrogen radicals reactive nitrogen species (RNS), which play major roles in oxidation. Kesari KK, Behari J. Fifty-gigahertz microwave exposure effect of radiations on rat brain. Dendritic spines, which are small protrusions that extend from dendritic shafts, are also cellular compartments containing signaling molecules that are important for synaptic transmission and plasticity [88,89,90,91]. WJZ wrote the paper and outlined this manuscript, LFW and XJH provided a detailed guidance throughout the article. PPT Scientific, technical publications in the nuclear field | IAEA Chronic microwave exposures were executed with 2.45GHz of either modulated (power density, 0.029mW/cm2; specific absorption rate, 0.019W/kg with a sinusoidal modulation of 400Hz) or non-modulated continuous sinusoidal wave (power density, 0.033mW/cm2; specific absorption rate, 0.023W/kg) for 2h daily for 1month. Int J Radiat Biol. Microwave radiation can induce oxidative and nitrosative stress, which lead to hippocampal neuronal and non-neuronal apoptosis via the oxidative damage of cellular constituents (i.e., nucleic acids, proteins and lipids) and subsequent over expression of p53, which up-regulates Bax and down-regulates pro-caspase-3 and full-length/uncleaved poly-ADP-ribose polymerase (PARP) 1, eventually inducing neuronal degeneration via apoptosis [76]. [102] exposed rats to 9.15MHz microwaves (SAR: 0.4mW/g) for 2h. They found that in the cerebellum of all the exposed animals, 11 genes were up-regulated from 1.34- to 2.74-fold, and one gene was down-regulated 0.48-fold. Microarray gene expression profiling of a human glioblastoma cell line exposed in vitro to a 1.9 GHz pulse-modulated radiofrequency field. Zhang proposed that the sex-dependent relationship between microwaves and the behavior of offspring may be related to sex hormones, and female rats may be equivalently protected by reducing oxidative stress levels. Effect of mobile radiation on health ppt . found that long-term treatment with a low dose of microwave radiation reduced the activity and the number of excitatory synapses. Human SH-SY5YNB cells were exposed to 2.1GHz W-CDMA modulated microwave radiation for 24h at a specific absorption rate of 0.491W/kg. The authors found that 2.4GHz microwave radiation reduced the expression of some miRNAs such as miR-106b-5p and miR-107 [98]. [61] found that after pregnant rats were irradiated with 9.417GHz microwaves, the behavior of their offspring differed, and the outcome was sex-dependent. Neurosci Lett. Microwave Radiations and Its Effects on Human Health-A Review [65] irradiated Wistar rats with 10, 30 and 50mW/cm2 microwaves, and the results showed that in the cerebral cortex, only glycine (Gly) and asparagine (Asp) levels were increased. Standard devices used by military personnel that may pose electromagnetic hazards include radars and missile systems. Synaptic plasticity is a special function of synapses, which play an important role in learning and memory processes [46], including structural and functional plasticity. These results explain the genetic mechanisms by which microwave radiation induces damage to learning and memory.

Professor, Asst Director at VIT Indian J Occup Environ Med. 2006;165:63644. Bioelectromagnetics. fMicrowave Radiation Comes From Many Sources, Including: Cell phones. Microwaves are widely used in broadcasting, communications and many industrial fields. LTP induction involves a signal transduction cascade that includes the release of glutamate from synaptic vesicles, activation of NMDAR at postsynaptic membranes, entry of Ca2+, and activation of Ca2+/calmodulin-dependent protein kinases (CaM kinases) II, IV and mitogen-activated protein kinase (MAPK) [71]. Glucose is the main energy source and is closely related to brain neurotransmitters and cholesterol synthesis [106]. Behav Brain Res. PubMed The authors therefore proposed that synaptic conduction disorders are associated with damage to cognitive functions. MicroRNAs: novel mechanism involved in the pathogenesis of microwave exposure on rats hippocampus. They summarized the characteristics and functions of hippocampus-related miRNAs following irradiation with microwaves, and these data laid a foundation that clarified the molecular mechanisms underlying microwave-induced injury to hippocampal learning and memory and suggested potential therapeutic targets. Qiao S, Peng R, Yan H, Gao Y, Wang C, Wang S, et al. 2005;25:10190201. These results indicated that mobile phone exposure affected the acquisition of learned responses in Wistar rats. Google Scholar. Ito K, Hirao A, Arai F, Takubo K, Matsuoka S, Miyamoto K, et al. Most studies have suggested that microwave radiation can cause EEG abnormalities in experimental animals and participants, but some negative results have also been reported in studies using low-power microwaves. [72] found that 2.856GHz, 50mW/cm2 pulsed microwave radiation caused persistent spatial memory impairments, disordered neurotransmitters, and varying degrees of damage in the hippocampus and synapses.

Impairment of long-term potentiation induction is essential for the disruption of spatial memory after microwave exposure. After exposure to microwave irradiation (an average power density of 30mW/m2 for 5min/d on five days a week for two consecutive months), the expression of NR2B was decreased in rats, the level of Glu was increased in the hippocampus and cerebrospinal fluid, spatial memory ability was decreased among rats with the TT genotype, and there was no change in the CC type and TC type animals. Among the variety of neurotransmitters, glutamate is the most abundant endogenous amino acid in the mammalian central nervous system. Wang L, Li X, Peng R, Gao Y, Zhao L, Wang S, et al. A metabolomic approach to screening urinary metabolites upon microwave exposure in monkeys. Thus, in the early developmental stage, chronic exposure to 2.4W/kg GSM microwaves may influence dendritic development and the formation of excitatory synapses in cultures of hippocampal neurons. 2006;27:16471. RF energy has the ability to heat human tissue, much like the way that microwave ovens heat food, and can be hazardous if the exposure is sufficiently intense or prolonged. Microwaves can influence mitochondria by damaging their structure [45], reducing ATP levels and affecting the activity of relevant enzymes such as succinate dehydrogenase (SDH) and cytochrome coxidase (COX) [119,120,121]. 2012;35:32534.
