Microwaves and Alzheimer's disease
China Created: 10 Oct 2016
Conclusion: The impact of wireless communication on human health is a mater of debate - Since there are widespread concerns regarding the deleterious effects of the exposure to microwaves on human tissues and the subsequent potential threat of carcinogenesis, we can conclude that the current exposure to microwaves during the use of cell phones is not safe for long-term exposure, despite the current scientific opinion.

Absorption of the cell phone signal into the brain of children does not exclude serious neuronal damage, as evidenced in rat studies (50). In addition, the increased risk of tumors of the head associated with long-term cell phone use is evident since radiofrequency may cause the blood-brain barrier to leak and to favor the damage of genetic material which consists of common precursors to cancer (51).

Accordingly, poor fertility and the increased chance of miscarriage and childhood cancer have been associated with cell phone storage in front pockets. Notably, the data suggested that the hippocampus can be injured by long-term microwave exposure (52), which may result in the impairment of cognitive function due to neurotransmitter disruption.

These results suggest that precautionary approach underlying the restrictive use of cell phones constitutes essential appropriate guidelines to follow although additional studies are needed.

Microwaves impair microvascular bloodflow
China Created: 28 Aug 2015
Abstract; Objective: The study aimed to investigate the effect of microwave radiation on microvasculature as well as the underlying mechanisms.

Methods
Sprague Dawley rats were exposed to microwave radiation. Microvascular diameters, flow velocity, blood perfusion, and permeability were measured. Cultured endothelial cells from microvessels were subjected to microwave radiation. Cytoskeleton, apoptosis, protein synthesis, and the markers of endoplasmic reticulum stress including 78-kDa glucose-regulated protein and calreticulin in endothelial cells were examined.

Results
Microwave radiation decreased microvascular diameters and blood perfusion, and increased the permeability of microvessles. And microwave radiation induced the formation of stress fibers, apoptosis, and LDH leakage from microvascular endothelial cells. Also, when microvascular endothelial cells were exposed to microwaves, protein synthesis was significantly elevated. We found that upon microwave radiation, the expression of 78-kDa glucose-regulated protein and calreticulin were greatly upregulated in microvascular endothelial cells. We also investigated possible signaling pathways for endoplasmic reticulum stress-initiated apoptosis. C/EBP homologous protein (CHOP) pathway was activated in microvascular endothelial cells exposed to microwaves.

Conclusions
Microwave radiation induces microvascular injury by triggering the apoptotic pathway of endoplasmic reticulum stress.

Blood-Brain-Barrier damage from 900 MHz confirmed and explained by Chinese Scientists
China Created: 19 May 2015
Exposure to 900 MHz electromagnetic fields activates the mkp-1/ERK pathway and causes blood-brain barrier damage and cognitive impairment in rats.

Abstract

With the rapid increase in the number of mobile phone users, the potential adverse effects of the electromagnetic field radiation emitted by a mobile phone has become a serious concern. This study demonstrated, for the first time, the blood-brain barrier and cognitive changes in rats exposed to 900 MHz electromagnetic field (EMF) and aims to elucidate the potential molecular pathway underlying these changes.

A total of 108 male Sprague-Dawley rats were exposed to a 900 MHz, 1 mW/cm(2) EMF or sham (unexposed) for 14 or 28 days (3h per day). The specific energy absorption rate (SAR) varied between 0.016 (whole body) and 2 W/kg (locally in the head). In addition, the Morris water maze test was used to examine spatial memory performance determination.

Morphological changes were investigated by examining ultrastructural changes in the hippocampus and cortex, and the Evans Blue assay was used to assess blood brain barrier (BBB) damage. Immunostaining was performed to identify heme oxygenase-1 (HO-1)-positive neurons and albumin extravasation detection. Western blot was used to determine HO-1 expression, phosphorylated ERK expression and the upstream mediator, mkp-1 expression.

We found that the frequency of crossing platforms and the percentage of time spent in the target quadrant were lower in rats exposed to EMF for 28 days than in rats exposed to EMF for 14 days and unexposed rats. Moreover, 28 days of EMF exposure induced cellular edema and neuronal cell organelle degeneration in the rat. In addition, damaged BBB permeability, which resulted in albumin and HO-1 extravasation were observed in the hippocampus and cortex.

Thus, for the first time, we found that EMF exposure for 28 days induced the expression of mkp-1, resulting in ERK dephosphorylation. Taken together, these results demonstrated that exposure to 900 MHz EMF radiation for 28 days can significantly impair spatial memory and damage BBB permeability in rat by activating the mkp-1/ERK pathway.

Inside an internet addiction treatment centre in China
China Created: 17 Dec 2014
IN CHINA, if you are a kid who spends a long time online, you had better watch out - Your parents may send you off for "treatment".

At the Internet Addiction Treatment Centre in Beijing, children must take part in military-style activities, including exercise drills and the singing of patriotic songs. They are denied access to the internet. One of the first experiences internees undergo is brain monitoring through electroencephalography (EEG). The programme is run by psychologist Tao Ran, who claims the brains of internet and heroin addicts display similarities.

The rise of such centres has, in some cases, been coupled with reports of brutality. One camp in Henan province was recently criticised after it was alleged that a 19-year-old girl died following corporal punishment doled out by officers.

These photographs [see source link] were taken by Fernando Morales during a four-day visit to the Beijing centre in June with journalist Zigor Aldama.

"We had heard stories about electroshocks, physical torture and confinement, but we found none of those," says Aldama.

"The children usually get angry when they know that they'll be locked in the centre, where parents put them without prior notice. They deny suffering an addiction. But as time goes by, I believe they are more sociable and calm. They get in better physical shape thanks to the sports training," Aldama says.

Association between mobile phone use and semen quality: a systemic review and meta-analysis
China Created: 8 Apr 2014
Summary: Possible hazardous health effects of radiofrequency electromagnetic radiations emitted from mobile phone on the reproductive system have raised public concern in recent years.

This systemic review and meta-analysis was prepared following standard procedures of the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and checklist.

Relevant studies published up to May 2013 were identified from five major international and Chinese literature databases: Medline/PubMed, EMBASE, CNKI, the VIP database and the Cochrane Central Register of Controlled Trials in the Cochrane Library. Eighteen studies with 3947 men and 186 rats were included in the systemic review, of which 12 studies (four human studies, four in vitro studies and four animal studies) with 1533 men and 97 rats were used in the meta-analyses.

Systemic review showed that results of most of the human studies and in vitro laboratory studies indicated mobile phone use or radiofrequency exposure had negative effects on the various semen parameters studied.

However, meta-analysis indicated that mobile phone use had no adverse effects on semen parameters in human studies. In the in vitro studies, meta-analysis indicated that radiofrequency radiation had detrimental effect on sperm motility and viability in vitro [pooled mean difference (MDs) (95% CI): −4.11 (−8.08, −0.13), −3.82 (−7.00, −0.65) for sperm motility and viability respectively]. As for animal studies, radiofrequency exposure had harmful effects on sperm concentration and motility [pooled MDs (95% CI): −8.75 (−17.37, −0.12), −17.72 (−32.79, −2.65) for sperm concentration and motility respectively].

Evidence from current studies suggests potential harmful effects of mobile phone use on semen parameters.

A further multicentred and standardized study is needed to assess the risk of mobile phone use on the reproductive system.

Magnetic fields exposure and childhood leukemia risk: A meta-analysis based on 11,699 cases and 13,194 controls
China Created: 15 Jan 2014
Abstract: Objective: To observe the association between childhood leukemia and magnetic field exposure.

Methods:
The literature was searched by PubMed, ProQuest, Web of Science (SCI) and Medline databases during 19972013. Heterogeneity in several studies was weighted by I-squared value. Publication bias was tested by funnel plot and Egger's test. Odds ratio (OR) and 95% CI were used to evaluate the association strength. The statistical analyses in present study were carried out by STATA software package (version 12.0, College Station, TX).

Results:
A total of 11,699 cases and 13,194 controls in 9 studies were stratified by different exposure cut-off points. On condition of the reference <0.1&#956;T, statistical association between magnetic field intensity &#8805;0.4&#956;T and childhood leukemia was exhibited (for total leukemia: OR=1.57, 95% CI=1.032.40; for acute lymphocytic leukemia: OR=2.43, 95% CI=1.304.55). On condition of the reference level of <0.2&#956;T, the positive association between magnetic field intensity &#8805;0.2&#956;T and childhood leukemia was found (OR=1.31, 95% CI=1.061.61).

Conclusions:
The result in this meta-analysis indicated that magnetic field exposure level may be associated with childhood leukemia.

Man Allergic To WiFi Lost Job as IT Consultant
China Created: 17 Oct 2013
58-year-old Guy Hudson is one of a growing number of people who identify themselves as being 'electrosensitive', who is 'allergic' to low electromagnetic fields - the kind produced by mobile phones and WiFi - and exposure leads to a raft of physical symptoms.

58-year-old Guy Hudson is one of a growing number of people who identify themselves as being 'electrosensitive'.

This group is 'allergic' to low electromagnetic fields - the kind produced by mobile phones and WiFi - and exposure leads to a raft of physical symptoms.

Guy has suffered for the past eight years. It began with headaches but developed into 24/7 debilitating pain and he was forced to give up his work as an IT consultant.

He spent his time researching what could be wrong with him and discovered the condition 'electro-hypersensitivity' (EHS).

Realizing his headaches got worse when he used his phone, Guy began to read up on the subject.

But it was when he had WiFi installed - and his symptoms noticeably worsened - that he was convinced.

The idea of electrosensitivity was first studied in the 1970s, but in recent years there has been an upsurge in those claiming to suffer from it.

Despite this scientific tests have failed to back up their claims and many experts remain skeptical.

4G Cell Phone Radiation Affects Brain Activity in Cell Phone Users
China Created: 24 Sep 2013
New peer-reviewed research finds that 30 minutes' exposure to 4G (LTE) cellphone radiation affects brain activity on both sides of the brain.

Sep. 23, 2013 - BERKELEY, Calif. -- The first study on the short-term effects of Long Term Evolution (LTE), the fourth generation cell phone technology, has been published online in the peer-reviewed journal, Clinical Neurophysiology. (1)

In a controlled experiment, researchers exposed the right ear of 18 participants to LTE cellphone radiation for 30 minutes. The source of the radiation was 1 centimeter from the ear, and the absorbed amount of radiation in the brain was well within international (ICNIRP) cell phone legal limits. The researchers employed a double-blind, crossover, randomized and counter-balanced design to eliminate any possible study biases.

The resting state brain activity of each participant was measured by magnetic resonance imaging (fMRI) at two times -- after exposure to LTE microwave radiation, and after a sham exposure.

The results demonstrated that LTE exposure affected brain neural activity not only in the closer brain region but also in the remote region, including the left hemisphere of the brain. The study helps explain the underlying neural mechanism for the remote effects of microwave radiation in the brain.

In 2011, Dr. Nora Volkow, Director of the National Institute on Drug Abuse, published a similar study in the Journal of the American Medical Association that received worldwide news coverage. Dr. Volkow reported that a 50 minute exposure to CDMA, a second generation cell phone technology, increased brain activity in the region of the brain closest to the cell phone. (2)

The current study establishes that short-term exposure to LTE microwave radiation affects the users' brain activity. Although LTE is too new for the long-term health consequences to have been studied, we have considerable evidence that long-term cell phone use is associated with various health risks including increased risk of head and neck cancers, sperm damage, and reproductive health consequences for offspring (i.e., ADHD).

Cell phone users, especially pregnant women and children, should limit their cell phone use. Moreover, cell phone users should not keep their phones near their head, breasts or reproductive organs when using the phone or whenever the phone is turned on unless it is in airplane mode.
