Modulation of HSP response in SH-SY5Y cells following exposure to microwaves of a mobile phone. 2013;42:428. It is noteworthy that most of the above mentioned studies were based on the theory that the effects caused by microwaves are non-thermal. Long term and excessive use of 900 MHz radiofrequency radiation alter microRNA expression in brain. The fields had an average power density of 0, 5, 10 or 50mW/cm2.

Othman H, Ammari M, Sakly M, Abdelmelek H. Effects of prenatal exposure to WIFI signal (2.45 GHz) on postnatal development and behavior in rat: influence of maternal restraint. After studying these effects, Hertel concluded that microwaving food leads to food degeneration. The levels of NMDA receptor subunits were increased 1 month after irradiation. Reactive oxygen species levels and DNA fragmentation on astrocytes in primary culture after acute exposure to low intensity microwave electromagnetic field. In the probe test, the exposed group could not locate the platform and exhibited a significantly higher mean latency (i.e., 3-fold higher) to reach the target quadrant, and they spent only half the time that the controls spent in the target quadrant.

Ito K, Hirao A, Arai F, Takubo K, Matsuoka S, Miyamoto K, et al. 1 Microwave radiation may also lead to skin cancer/health problems when we are within the radius of a cell phone tower in a certain specified limited distance. In summary, there is evidence that microwave radiation can lead to alterations in protein synthesis or protein modifications; however, the results are controversial. Quantitation, regional vulnerability, and kinetic modeling of brain glucose metabolism in mild Alzheimers disease. [80] found that irradiation with 900MHz, 2W/kg continuous microwaves for 24h induced an increase in rat neuronal apoptosis. The results showed that gestational Wi-Fi exposure and restraint adversely affected offspring neurodevelopment and behavior in adulthood. A large number of studies have shown that microwave radiation can cause a series of adverse reactions in the central nervous system, including sleep disorders in addition to learning and memory impairments. Studies have extensively explored the underlying mechanisms by which microwaves influence learning and memory functions, especially synaptic structures and functions, oxidative stress and apoptosis, protein synthesis, genes and individual susceptibility and energy metabolism.

Glucose is the main energy source and is closely related to brain neurotransmitters and cholesterol synthesis [106]. 2013;73:4737. Bioelectromagnetics. Microwaves of 50mW/cm2 increased the levels of the major excitatory amino acids Asp and glutamic acid (Glu) and the inhibitory amino acids gamma-aminobutyric acid (GABA) and Gly, while 6h later in the 30mW/cm2 group, the level of Gly was reduced in the cerebral cortex. broad definition in terms of frequencies between. In industrial fields, exposure is usually occupational, and its sources include the surgical and physiotherapeutic use of diathermy, dielectric heating (i.e., heating and vulcanization applications), microwave ovens, magnetic resonance imaging (MRI) medical diagnostic equipment, radar, military and research microwave systems, electricity-supplying networks, and electricity-distributing and transmitting equipment [3]. Kumar M, Singh SP, Chaturvedi CM. Part of 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]. Johnson OL, Ouimet CC. [105] identified stable C-T mutation sites at 217 points by screening for SNPs in the GRIN2B promoter region in rats. Neuroreport. 2006;27:295306. Gage FH, Kelly P, Bjorklund A. The visual reaction time and short-term memory of healthy male and female workers at a radar site with a frequency range of 218GHz was recorded with a simple blind computer-assisted-visual reaction time test or modified Wechsler Memory Scale test. The frequencies of these devices are listed in Table1. . PubMed Per the FDA, the microwave can heat human skin. To investigate the effects of microwaves radiation on apoptotic activity, cell viability, and cell cycle progression, which can provide information about microwaves radiation effects on neural cells over the period from embryonic stages to infants.
