Exposure to 900 MHz electromagnetic fields causes blood-brain barrier damage and cognitive impairment in rats
China Created: 29 Jan 2015
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/cm2 EMF or sham (unexposed) for 14 or 28 days (3 h 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.

The literature was searched by PubMed, ProQuest, Web of Science (SCI) and Medline databases during 1997–2013. 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).

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 <0.1μT, statistical association between magnetic field intensity ≥0.4μT and childhood leukemia was exhibited (for total leukemia: OR=1.57, 95% CI=1.03–2.40; for acute lymphocytic leukemia: OR=2.43, 95% CI=1.30–4.55). On condition of the reference level of <0.2μT, the positive association between magnetic field intensity ≥0.2μT and childhood leukemia was found (OR=1.31, 95% CI=1.06–1.61).

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.

China Created: 28 Jan 2013
Rooftops at HKUST are clogged with ever more mobile phone antennae – so much so that residents fear a link between radiation and cancer cases.

They have added so many new antennae … it is simply unacceptable AN ACADEMIC AT HKUST
11 The number of mobile phone antennae on two apartment blocks housing 22 families at HKUST
It must rank as one of the most spectacular university campuses in the world – a dramatic vista commanding vertigo- inducing views across some of the most unspoilt stretches of coastline in the New Territories.
But compare the outlook from the dizzy heights of the University of Science and Technology in Clear Water Bay to that of a few years ago and you may notice that something new breaks up the horizon of outlying islands and passing yachts: dozens of mobile phone antennae.
In a process that began some six years ago, telecom companies have paid the university to put more and more antennae on teaching blocks and student and staff quarters to improve mobile phone signals in a once notoriously patchy corner of the city for reception.
From just a handful of antennae in 2007, long- term campus residents count 87 rooftop antennae, or base stations, dotted liberally across campus buildings in what may be the highest density of mobile phone antennae per head of population anywhere in Hong Kong.
For the university, with its student body of 12,600 and teaching staff of over 500, it’s a win- win arrangement.
Mobile phone companies improve their coverage, including the signal on campus, and provide welcome funds for the university’s scholarship programme ( although it will not say precisely how much).
But for some academics with young families living on campus – who have seen a new batch of antennae spring up over the Christmas break – the antennae have gradually changed from an architectural oddity into a nagging health concern.
Fuelled by overseas stories of alleged rises in cancer rates in areas close to clusters of mobile phone antennae, they fear their health and that of their children is being put in jeopardy.
They say they have not been informed when additional antennae are put in place and are now preparing an online petition that will demand, among other things, to know why the university has allowed so many antennae and how much money it has been paid.
Concerns over the antennae have escalated to the point where residents are questioning whether there is a link between cancer cases on the campus in recent years involving both teaching staff and students.
Speaking on condition of anonymity, because of the impact she fears it would have on her job, one academic said the erection of new antennae this month meant there were 11 antennae on just two campus apartment blocks housing 22 families – many of them with young children. One block has a kindergarten on the ground floor.
“When the first two mobile phone antennae appeared on staff residential blocks in 2007, some 30 to 40 residents signed a letter expressing concern over it,” the woman said. “One lady living directly below the antennae with two young children was quite upset about it.
“We were told that radiation levels were within safe limits and that everything was safe. We let the matter lie until now when more and more antennae have appeared.”
She claimed there had been 10 cases of cancer in the past four years among residents of the 19 tower blocks where academic staff and their families live, some of them fatal, and a case of advanced lung cancer in a postgraduate student who was a nonsmoker.
Although there was no evidence of any link between the antennae and the cancer cases, suspicions were heightened by what residents see as the apparent secrecy surrounding their installation, she argued.
“They should have the decency to inform us when they put up additional antennae. A lot of my neighbours don’t know what is going on.
“I have a neighbour with young children and she had no idea about the antennae until I told her.
“They have added so many new antennae around the campus. It is simply unacceptable.
“We feel the Environment Bureau should step in and investigate,” she said.
“We want the university to tell us what the safe limit is for mobile phone antennae, because we seem to have so many here. We want to know why they are putting up so many antennae here and how much money they are getting from it.
“It may be that they rely on this money to survive. But is it worth sacrificing the health of the staff and the students?”
Another member of the teaching staff questioned why mobile phone companies did not place antennae on nearby deserted hillsides rather than on the top of apartment blocks.
“There are so many hills around here, so surely they could build a tower away from residential areas,” the member of staff said. “Perhaps they are just taking this option because it is cheaper, but why is the university allowing this?
“If you go around Hong Kong, you can go to posh apartment blocks and there are no mobile phone antennae there because people won’t allow it. But if you go to run- of- the- mill apartment blocks you will see a lot of mobile phone antennae.”
Similarly, the member of staff said apartment blocks on campus housing senior university employees did not have antennae on top while those housing more junior employees did.
“Our biggest concern is for the health of our children,” the employee said. “These are staff quarters and a lot of children live here. Students are here for two or three years but we stay here for years and our children grow up here.”
The member of staff added: “Academics come here from around the world with their young families. We call ourselves Asia’s ‘ world city’. How can we subject them and their families to this without even warning them?”
Responding to the concerns, a spokeswoman for the university said: “The university has been closely monitoring all antenna installations to ensure they fulfil conditions stated in the code of practice established by the Office of the Telecommunications Authority, which was merged with the Broadcasting Authority to become the Office of the Communications Authority.
“In addition, the university has been performing regular antennae surveys to monitor for any potential safety and health impact.
“All surveys conducted by the university show exposure to antenna- associated electromagnetic radiation on campus remain well within allowable safety limit[ s].
“The electromagnetic [ EM] radiation emitted by the telephone base stations … are in a conical- fan shape and essentially directed away from the building, towards the horizon with a slight downward tilt.
“The EM radiation weakens rapidly with distance from the antenna, and the exposure for those at distances exceeding 10 metres from these base stations will be much less than the applicable World Health Organisation exposure guidelines.”
Radiation exposure from base stations was, in any case, negligible, the spokeswoman stressed. “Generally it is impossible for people to stand in close proximity, such as within a few metres, directly in front of these antennae,” she said.
“Secondly, most of these antennae are located in a controlled area where only authorised personnel such as maintenance staff may have access.”
She said there was a strong demand for phone coverage, adding: “The number of mobile phone antenna is dictated by topography of the site and configuration of the buildings.”
The spokeswoman declined to say how much was paid by mobile phone companies but said all income generated went to the university’s undergraduate scholarship fund.
She added: “The university pays close attention to the wellbeing of its members and is committed to providing a safe, environmentally friendly and enabling environment for the campus community.”
A spokesman for the Office of the Communications Authority said mobile phone operators had to obtain its approval for base stations.
“Approval will be granted only if the radio base station concerned meets, among other things, the radiation safety requirement,” the spokesman said.
After consulting the Department of Health, guidelines issued by the International Commission on Non- Ionising Radiation Protection ( ICNIRP) had been adopted in Hong Kong and there was “no evidence” radiation levels below those levels caused adverse health effects.
There was no requirement for residents in blocks where base stations were to be installed to be informed, the spokesman said.
If members of the public were concerned about radiation, the office could arrange site visits, the spokesman added.
“If the measures results suggest that the [ radiation] levels have been exceeded or even approach the ICNIRP limits, the MNOs [ mobile phone network operators] concerned are required to implement remedial action including placing antennas at a higher location, lowering the transmitting powers and restricting access to high [ radiation] areas.”
From 2010 to last November, the office conducted 896 on- site measurements and only two base stations required remedial action to lower radiation levels, the spokesman said.
Such assurances are unlikely to bring an end to the concerns of some families living directly below the antennae.
“I’ve been told that the voltage of the antennae can be turned up or down – so if the telecom companies know an inspection is taking place, they can turn the antennae down before any inspection,” the member of the teaching staff said.
“I don’t trust the office’s measurements. We are trying to get a monitor of our own so that we can take random measurements ourselves and find out the real level of radiation our families are being exposed to.”

Chinese Put Cancer of the Parotid Gland on Center Stage
China Created: 19 Apr 2011
Chinese researchers in Beijing are seeing some of the highest rates of cancer ever reported in any cell phone study. They have found that long-term, heavy users have rates of malignant parotid gland tumors that are seven to 13 times higher than might otherwise be expected.

The raw data --that is, before being adjusted for other possible risk factors like sex, age, income, smoking status and the like--
point to cancer risks that are elevated 10-fold, 20-fold, and even 30-fold, depending on the type of tumor and how heavy cell phone use is defined.

Wireless industry wants to put a Mobile-Phone into Every Device
China Created: 7 Feb 2011
HONG KONG -- The GSMA today announced the formation of a task force of mobile operators to explore the development of an embedded SIM that can be remotely activated. The move is expected to enable the design of exciting new form factors for mobile communications. It will also speed the development of M2M services by making it easier to bring mobile broadband to non-traditional devices such as cameras, MP3 players, navigation devices and e-Readers, as well as smart meters.

"The traditional SIM has been an important innovation in mobile telephony, and has provided many benefits to consumers in terms of security, portability of contacts, and ease of portability of devices across networks," said Rob Conway, CEO and Member of the Board of the GSMA. "As our industry moves from connecting phones to connecting a wide range of devices, it is apparent that the embedded SIM could deliver even greater flexibility. The embedded SIM will provide assured levels of security and portability for consumers, as well as provide additional functionality for enabling new services such as e-Wallet and NFC applications."

The GSMA-led task force comprises a group of leading technical experts drawn from operators including AT&T, China Mobile, Deutsche Telekom, France Telecom Orange, KT, NTT DOCOMO, SK Telecom, Telecom Italia, Telefonica, Verizon Wireless and Vodafone. The group will work in cooperation with major SIM producers.

The task force will analyse market requirements and deliver a technical solution as an evolution of the current SIM provisioning mechanisms. The proposed embedded SIM solution will include programmable SIM card capabilities to enable remote activation.

The group is expected to complete the analysis of market requirements by January 2011. The resulting technical solution will be built on the principles of openness and standardisation. Devices featuring the new SIM activation capability are expected to appear in 2012. Traditional SIM-supported devices will continue to work on existing networks.

About the GSMA
