Chronic microwave exposure could induce cognitive deficit an

Post by Kasper »

The increased use of microwaves raises concerns about its impact on health including cognitive function in which neurotransmitter system plays an important role. In this study, we focused on the serotonin system and evaluated the long term effects of chronic microwave radiation on cognition and correlated items. Wistar rats were exposed or sham exposed to 2.856GHz microwaves with the average power density of 5, 10, 20 or 30mW/cm2 respectively for 6min three times a week up to 6weeks. At different time points after the last exposure, spatial learning and memory function, morphology structure of the hippocampus, electroencephalogram (EEG) and neurotransmitter content (amino acid and monoamine) of rats were tested. Above results raised our interest in serotonin system. Tryptophan hydroxylase 1 (TPH1) and monoamine oxidase (MAO), two important rate-limiting enzymes in serotonin synthesis and metabolic process respectively, were detected. Expressions of serotonin receptors including 5-HT1A, 2A, 2C receptors were measured. We demonstrated that chronic exposure to microwave (2.856GHz, with the average power density of 5, 10, 20 and 30mW/cm2) could induce dose-dependent deficit of spatial learning and memory in rats accompanied with inhibition of brain electrical activity, the degeneration of hippocampus neurons, and the disturbance of neurotransmitters, among which the increase of 5-HT occurred as the main long-term change that the decrease of its metabolism partly contributed to. Besides, the variations of 5-HT1AR and 5-HT2CR expressions were also indicated. The results suggested that in the long-term way, chronic microwave exposure could induce cognitive deficit and 5-HT system may be involved in it.

Note that WIFI is around 2.4 GHz... I would hope that WIFI is just innocent, but it may be wise to at least not sit next to a WIFI router during the day.

The effects of microwave treatments on the thermoxidative degradation of five edible fats and oils (sunflower oil, high oleic sunflower oil, virgin olive oil, olive oil, and lard) were determined. The samples were subjected to the following three well-controlled treatments:  (a) microwave heating, (b) heating in a conventional electric oven, and (c) exposure to microwave energy without heating. A comparative study was carried out on the deterioration of the oils as a result of microwave and conventional oven heating. Degradations were quantified by means of a combination of chromatographic techniques and related analytical index. Data analysis showed greater alterations in microwave-heated samples than in corresponding samples heated in a conventional oven. Finally, microwave energy, without heating (temperature lower than 40 °C), produced no oil alterations.
