"Morphological and antioxidant impairments in the spinal cord of male offspring rats following exposure to a continuous 900MHz electromagnetic field during early and mid-adolescence"

"Abstract

The effects of devices emitting electromagnetic field (EMF) on human health have become the subject of intense research among scientists due to the rapid increase in their use. Children and adolescents are particularly attracted to the use of devices emitting EMF, such as mobile phones. The aim of this study was therefore to investigate changes in the spinal cords of male rat pups exposed to the effect of 900MHz EMF. The study began with 24 Sprague-Dawley male rats aged 3 weeks. Three groups containing equal numbers of rats were established-control group (CG), sham group (SG) and EMF group (EMFG). EMFG rats were placed inside an EMF cage every day between postnatal days (PD) 21 and 46 and exposed to the effect of 900MHz EMF for 1h. SG rats were kept in the EMF cage for 1h without being exposed to the effect of EMF. At the end of the study, the spinal cords in the upper thoracic region of all rats were removed. Tissues were collected for biochemistry, light microscopy (LM) and transmission electron microscopic (TEM) examination. Biochemistry results revealed significantly increased malondialdehyde and glutathione levels in EMFG compared to CG and SG, while SG and EMFG catalase and superoxide dismutase levels were significantly higher than those in CG. In EMFG, LM revealed atrophy in the spinal cord, vacuolization, myelin thickening and irregularities in the perikarya. TEM revealed marked loss of myelin sheath integrity and invagination into the axon and broad vacuoles in axoplasm. The study results show that biochemical alterations and pathological changes may occur in the spinal cords of male rats following exposure to 900MHz EMF for 1h a day on PD 21-46."

Massachusetts town north of Boston is allowing a utility to de-colocate from multiple existing distributive antenna systems (DAS), and install multiple new omni directional antennas within a 475 foot radius of the existing DAS units.. FCC reports indicate the utilities service coverage is 5G or 5G+ at all of the DAS units. There are no gaps in coverage. It appears to be a financial maneuver disguised as an up grade from DAS units, that provide optimum coverage as reported by the utility to the FCC coverage maps,

The nine new nodes create emission over lap with the existing DAS units. The emission overlap will not be monitored or measured by the town or the utility. At one application location, two DAS units and two omni directional units will all be located within 1/3 of a mile or less from each other. This creates emission overlap of either two or three nodes, none of which will have emission levels monitored/tested by the town or utility.

There are cancer clusters around at least one node including lung, prostate, follicular. Residents nearby report unexplained long term symptoms of not feeling well. The town approves the applications under the premiss that they cannot deny or redirect the utility. The residents become victims of the results.

"Abstract

Some studies have shown that exposure to electromagnetic field (EMF) may result in structural damage to neurons. In this study, we have elucidated the alteration in the hippocampal function of offspring Wistar rats (n = 8 rats in each group) that were chronically exposed to mobile phones during their gestational period by applying behavioral, histological, and electrophysiological tests. Rats in the EMF group were exposed to 900 MHz pulsed-EMF irradiation for 6 h/day. Whole cell recordings in hippocampal pyramidal cells in the mobile phone groups did show a decrease in neuronal excitability. Mobile phone exposure was mostly associated with a decrease in the number of action potentials fired in spontaneous activity and in response to current injection in both male and female groups. There was an increase in the amplitude of the afterhyperpolarization (AHP) in mobile phone rats compared with the control. The results of the passive avoidance and Morris water maze assessment of learning and memory performance showed that phone exposure significantly altered learning acquisition and memory retention in male and female rats compared with the control rats.

As Chief Scientific Officer of Children’s Health Defense, I urge the Department of Health and Human Services (HHS) to prioritize independent, transparent research into the biological and health effects of wireless radiation. As wireless infrastructure expands, we must address critical gaps in scientific understanding, reevaluate outdated federal exposure guidelines, and investigate potential risks to children and other vulnerable populations. Protecting public health requires rigorous science, transparency, and a commitment to following the evidence wherever it leads.

The OFT and EPM were performed to evaluate the anxiety-related behavior of offspring. The results of the OFT indicated that the total distance covered by the offspring of the various study groups did not differ significantly. This suggested that the mice did not differ in motor ability (Fig. 1A). However, frequency of entries into and duration of time spent in the center zone for the Radiation group of mice were lower compared with the Control and Sham-control mice (P < 0.05), suggesting an increase in the anxiety-related behavior of exposed mice (for both male and female mice) (Fig. 1B and C)."

Hello, my name is Nathaniel Jackson, and I must make a comment on this topic, because it appears that the government officials who have jurisdiction to investigate and to dismantle those private cooperation who are responsible for such actions, are ignoring this for what ever reason they may have.

I must start by saying that, the people's who are behind those operations, don't give a hoot's about the harm that can be done to peoples through such technologies that they are executing to achieve their goals.

Secondly, back in the early years of 1990s, it was a program shown on the Discovery channel about the deadly affects of Electromagnetic Fields (EMFs), Radio frequency (RF), Radiation, and Wireless Radiation Exposure, and it was concluded that all of it was going to make a lots of people's sick, and kill a lots of people's.

Thirdly, the government officials who have the authority to stop those private cooperation from installing all of those devices that are putting out harmful Electromagnetic Fields, and radio frequency signals, and wireless radiation, must be a member of the same gang as those private cooperation individuals. Because I can't see no way in hell on earth why anyone in authority would put themselves in harm's way, when they have to power to stop what is happening. Unless they are in cahoots with it all. But , if those government officials who have jurisdiction to stop those devil's, are not a member of their gang, why in hell on earth would you take a job that would requires you to go after, and to take down some of the most powerful people's in America and around the world.

The bottom line is this, the wealthy people's who are behind all of this madness, don't care nothing about the safety and well being of the people's who are not wealthy and apart of their circle, which is everyone regardless of your high ranking government official job, and anything else that you are associated with on that level. Therefore, if they don't have no people's helping them to achieve their goals, they don't have no legs to stand on.

"Testing of behavioral and cognitive development in rats after prenatal exposure to 1800 and 2400 MHz radiofrequency fields"

"Abstract

The objective of the study was to explore the effects of behavioral and cognitive development in rats after prenatal exposure to 1800 and 2400 MHz radiofrequency fields. Pregnant female rats were exposed to radiofrequency fields beginning on the 21st day of pregnancy. The indicators of physiological and behavioral development were observed and measured in the offspring rats: Y maze measured at 3-weeks postnatal, open field at 7-weeks postnatal, and the expression of N-methyl-D-aspartate receptors (NMDARs) measured by reverse transcription-PCR in the hippocampus at 9-weeks postnatal. The body weight of the 1800 MHz group and the 1800 MHz + WiFi group showed a downward trend. The eye opening time of newborn rats was much earlier in the WiFi group than in the control group. Compared to the control group, the overall path length of the 1800 MHz + WiFi group was shortened and the stationary time was delayed. The path length of the WiFi group was shortened and the average velocity was increased in the error arm. The 1800 MHz + WiFi group displayed an increased trend in path length, duration, entry times and stationary time in the central area. In both the 1800 MHz + WiFi and WiFi groups, NR2A and NR2B expression was down-regulated, while NR2D, NR3A and NR3B were up-regulated. Moreover, NR1 and NR2C in the WiFi group were also up-regulated. Prenatal exposure to 1800 MHz and WiFi radiofrequency may affect the behavioral and cognitive development of offspring rats, which may be associated with altered mRNA expression of NMDARs in the hippocampus."

COMMENT My legs and lower back were pained to the point that walking could only happen with support – looking back after some time this could be linked to a new TETRA mast which had been installed in the village. Two wires crossing the gardens were changed to high-tension wires that would enable broadband to be carried. Two years later in 2010 a shocking event further changed my life after an electrical company arrived where I lived and proceeded to cut down trees in the area, under wires and to allow accessible connection to the mast. Electricity meters were also changed in all the houses. At 5.00 pm on that evening my body was assaulted on many levels with effects such as a feeling of alert/panic, palpitations, my burning skin felt as if it wanted to turn inside-out. These were combined with a high-pitched ‘noise’ and a second ‘noise’ that sounded like a diesel engine running. Over the next few nights my body was still on alert and my body was actually thrown out of the bed and in those few seconds I woke up balancing myself on my feet with my arms stretched out before me. The companies related to the mast and electricity were contacted and sound professionals but none were helpful. An inability to sleep as my body was being tormented led to personal attempts to find the source of the noise and wandering down streets and lanes in the dead of night became usual. No source was ever found. Why – because what was happening had already been well studied by Alan Frey in USA and it was called ‘microwave hearing’. The inability to sleep saw attempts made to seek sleep, rest and peace in the car, shed, tent in the garden etc but the ‘noise’ was everywhere. For safety in the dark hours I had to sleep on a mattress downstairs after removing electrical wiring in the fire alarms etc. That was the first physical indication that it was definitely electricity that was causing these effects. Occasionally it was necessary to ask friends if I could spend a night in their house as my home and village was, for me, dangerous. The ‘noise’ was not in other parts of the county and this was another clue leading to my discovery that I was suffering from…

"Wi-Fi (2.45 GHz)- and Mobile Phone (900 and 1800 MHz)-Induced Risks on Oxidative Stress and Elements in Kidney and Testis of Rats During Pregnancy and the Development of Offspring"

"Abstract

The present study was designed to determine the effects of both Wi-Fi (2.45 GHz)- and mobile phone (900 and 1800 MHz)-induced electromagnetic radiation (EMR) on oxidative stress and trace element levels in the kidney and testis of growing rats from pregnancy to 6 weeks of age. Thirty-two rats and their 96 newborn offspring were equally divided into four different groups, namely, control, 2.45 GHz, 900 MHz, and 1800 MHz groups. The 2.45 GHz, 900 MHz, and 1,800 MHz groups were exposed to EMR for 60 min/day during pregnancy and growth. During the fourth, fifth, and sixth weeks of the experiment, kidney and testis samples were taken from decapitated rats. Results from the fourth week showed that the level of lipid peroxidation in the kidney and testis and the copper, zinc, reduced glutathione (GSH), glutathione peroxidase (GSH-Px), and total antioxidant status (TAS) values in the kidney decreased in the EMR groups, while iron concentrations in the kidney as well as vitamin A and vitamin E concentrations in the testis increased in the EMR groups. Results for fifth-week samples showed that iron, vitamin A, and β-carotene concentrations in the kidney increased in the EMR groups, while the GSH and TAS levels decreased. The sixth week results showed that iron concentrations in the kidney and the extent of lipid peroxidation in the kidney and testis increased in the EMR groups, while copper, TAS, and GSH concentrations decreased. There were no statistically significant differences in kidney chromium, magnesium, and manganese concentrations among the four groups. In conclusion, Wi-Fi- and mobile phone-induced EMR caused oxidative damage by increasing the extent of lipid peroxidation and the iron level, while decreasing total antioxidant status, copper, and GSH values. Wi-Fi- and mobile phone-induced EMR may cause precocious puberty and oxidative kidney and testis injury in growing rats"

"Effects of Prenatal and Postnatal Exposure to 50-Hz and 3 mT Electromagnetic Field on Rat Testicular Development"

"Abstract

Background and objectives: It has been shown that electromagnetic fields (EMFs) have negative effects on the reproductive system. The biological effects of EMF on the male reproductive system are controversial and vary depending on the frequency and exposure time. Although a limited number of studies have focused on the structural and functional effects of EMF, the effects of prenatal and postnatal EMF exposure on testes are not clear. We aimed to investigate the effects of 50-Hz, 3-mT EMF exposure (5 days/wk, 4 h/day) during pre- and postnatal periods on testis development. Materials and Methods: Pups from three groups of Sprague-Dawley pregnant rats were used: Sham, EMF-28 (EMF-exposure applied during pregnancy and until postnatal day 28), EMF-42 (EMF-exposure applied during pregnancy and until postnatal day 42). The testis tissues and blood samples of male offspring were collected on the postnatal day 42. Results: Morphometric analyses showed a decrease in seminiferous tubule diameter as a result of testicular degeneration in the EMF-42 group. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were decreased in the EMF-42 group. Lipid peroxidation levels were increased in both EMF groups, while antioxidant levels were decreased only in the EMF-28 group. We found decreased levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF1) in the EMF-42 group, and decreased levels of the SRC homology 3 (SH3) and multiple ankyrin repeat domain (SHANK3) in the EMF-28 group in the testis tissue. Conclusions: EMF exposure during pre- and postnatal periods may cause deterioration in the structure and function of testis and decrease in growing factors that would affect testicular functions in male rat pups. In addition to the oxidative stress observed in testis, decreased SHANK3, VEGF, and IGF1 protein levels suggests that these proteins may be mediators in testis affected by EMF exposure. This study shows that EMF exposure during embryonic development and adolescence can cause apoptosis and structural changes in the testis"

"Postnatal development and behavior effects of in-utero exposure of rats to radiofrequency waves emitted from conventional WiFi devices"

"Abstract

The present work investigated the effects of prenatal exposure to radiofrequency waves of conventional WiFi devices on postnatal development and behavior of rat offspring. Ten Wistar albino pregnant rats were randomly assigned to two groups (n=5). The experimental group was exposed to a 2.45GHz WiFi signal for 2h a day throughout gestation period. Control females were subjected to the same conditions as treated group without applying WiFi radiations. After delivery, the offspring was tested for physical and neurodevelopment during its 17 postnatal days (PND), then for anxiety (PND 28) and motricity (PND 40-43), as well as for cerebral oxidative stress response and cholinesterase activity in brain and serum (PND 28 and 43). Our main results showed that the in-utero WiFi exposure impaired offspring neurodevelopment during the first seventeen postnatal days without altering emotional and motor behavior at adult age. Besides, prenatal WiFi exposure induced cerebral oxidative stress imbalance (increase in malondialdehyde level (MDA) and hydrogen peroxide (H2O2) levels and decrease in catalase (CAT) and superoxide dismutase (SOD) activities) at 28 but not 43days old, also the exposure affected acethylcolinesterase activity at both cerebral and seric levels. Thus, the current study revealed that maternal exposure to WiFi radiofrequencies led to various adverse neurological effects in the offspring by affecting neurodevelopment, cerebral stress equilibrium and cholinesterase activity"

"Does Exposure of Smart Phones during Pregnancy Affect the Offspring’s Ovarian Reserve? A Rat Model Study"

"Abstract

We investigated the effect of prenatal exposure to smart phone radiation and the protective effect of omega-3 on ovarian reserve of offspring. Methods: 24 pregnant Wistar albino rats were divided into four groups. Group-I received neither radiofrequency (RF) radiation nor omega-3, group-II received RF, group-III received RF radiation and 300 mg omega-3 and group-IV received RF radiation and 600 mg Omega-3 till birth. At 42 days, bilateral oophorectomy was performed on all female offspring for follicle count and immunohistochemical staining (GDF9, FOXO1 and TUNEL). Results: Group-II had significantly lower mean number of primordial (p = 0.006), secondary follicles(p = 0.003) and a higher atresia score. Group-III variables were comparable with group-I variables. Group-IV had statistically higher median number of atretic follicles than group-I (p = 0.023). Conclusions: Ovarian reserve of offspring diminished with RF exposure during pregnancy. Omega-3 supplementation during pregnancy may reduce the potential premature ovarian failure."

"Electrical Grounding Improves Vagal Tone in Preterm Infants"

"Abstract

Background: Low vagal tone (VT) is a marker of vulnerability to stress and the risk of developing necrotizing enterocolitis in preterm infants. Electric fields produced by equipment in the neonatal intensive care unit (NICU) induce an electric potential measurable on the skin in reference to ground. An electrical connection to ground reduces the skin potential and improves VT in adults. Objectives: We aimed to measure the electric field strengths in the NICU environment and to determine if connecting an infant to electrical ground would reduce the skin potential and improve VT. We also wished to determine if the skin potential correlated with VT. Methods: Environmental magnetic flux density (MFD) was measured in and around incubators. Electrical grounding (EG) was achieved with a patch electrode and wire that extended to a ground outlet. We measured the skin potential in 26 infants and heart rate variability in 20 infants before, during, and after grounding. VT was represented by the high-frequency power of heart rate variability. Results: The background MFD in the NICU was below 0.5 mG, but it ranged between 1.5 and 12.7 mG in the closed incubator. A 60-Hz oscillating potential was recorded on the skin of all infants. With EG, the skin voltage dropped by about 95%. Pre-grounding VT was inversely correlated with the skin potential. VT increased by 67% with EG. After grounding, the VT fell to the pre-grounding level. Conclusion: The electrical environment affects autonomic balance. EG improves VT and may improve resilience to stress and lower the risk of neonatal morbidity in preterm infants"

"A Prospective Study of In-utero Exposure to Magnetic Fields and the Risk of Childhood Obesity"

"Abstract

We conducted a prospective study to examine whether in-utero exposure to magnetic fields (MFs) increases the risk of childhood obesity. Participating women carried a meter measuring MF levels during pregnancy and 733 of their children were followed up to 13 years to collect clinically recorded information on growth patterns with 33 weight measurements per child on average. Prenatal exposure to high MF level was associated with increased risk of being obese in offspring than those with lower MF level (odds ratio = 1.69, 95% confidence interval: 1.01–2.84). The association demonstrated a dose-response relationship and was stronger (more than 2.3 fold increased risk) among children who were followed up to the end of the study. The association existed only for persistent obesity, but not for transitory (unlikely) obesity. Maternal exposure to high MF during pregnancy may be a new and previously unknown factor contributing to the world-wide epidemic of childhood obesity/overweight."
