The effects of mobile phones on apoptosis in cerebral tissue: an experimental study on rats.

Abstract

INTRODUCTION:

The concern about mobile phone effects is increasing as the number of users increasing too. Different studies have different results, so this topic is still open to discussion. Aim of this report was to investigate the effects of the mobile phones on the Bcl-2 gene and p53 proteins in rat brains.

MATERIALS AND METHODS:

In the study group of 10 rats; mobile phones that spread EMW at a frequency between 1900-2100 MHz and Specific Absorption Rate range between 0.005 W/kg and 0.288 W/kg (Dialing mode), 0.004 W/kg and 0.029 W/kg (Calling mode) were attached to rat ears for simulating usage in daily life for 7 times a day during 5 minutes (3 seconds dialing mode, 4 minutes and 47 seconds of calling mode) for a four week period. Sham group (n=10) rats were only immobilized without EMW exposure. Another group of rats (n=10) were counted as control without any application. immunohistopathological examination was performed for p53 and Bcl-2 expression.

RESULTS:

Immunohistopathological examinations revealed that the samples in the study group had more p53 and Bcl-2 positive stained cells and they were stained denser. In both evaluations, these differences between the study and control group were found statistically significant (p < 0.003); In Bcl-2 evaluation statistically significant difference was found between study and sham group to (p < 0.005); however, the p53 evaluation between the study and the sham group did not show any statistically significant difference (p > 0.005).

CONCLUSIONS:

Our results showed that the electro-magnetic waves emitted by the mobile phones may have effect on apoptosis. Besides, obtained data revealed that more realistic application of mobile phones during experiments is more important as expected.

Teachers and students often grumble about end of the year tests,but at the Los Angeles Unified School District, the complaints are mounting:
  • iPads the district purchased to take new state competency tests aren’t getting online.
  • They’re having trouble connecting to keyboards.
  • And, in some cases, they’re not turning on at all.
"It took a while for it to work, and I only ended up answering three questions by the end of class," said Lia Peña, a junior at Hamilton High School in Culver City.
Peña's classmate, Antonia Lorenzo, compared the iPads' sluggish start to the healthcare.gov's numerous technical glitches.
"The whole system didn't work. When everyone goes on at once, it overloads it," she said.
To prepare for the new digital test, the district spent well over $20 million on 45,000 iPads. Of those, the district says about 10 wouldn't turn on at all or had trouble charging, and 100 had configuration issues. Defective devices were replaced.
The school board's curriculum and instruction committee was scheduled to address testing progress at its meeting Tuesday, but the item was pulled from the agenda. Committee chair and board member Monica Ratliff said the four-hour meeting was going too long.
LAUSD officials declined to be interviewed, but spokeswoman Shannon Haber said the technology team works quickly to resolve any technical issues, and for many schools, the process is going smoothly, she said.
Switched back to PCs
Some principals have switched back to old desktop computers with more reliable Internet connections. Staff at Millikan Middle, Pomelo Community Charter and Thomas Starr King Middle have reported problems with logging iPads on to the Internet.
Wil Page, an English and history teacher at  Starr King in Silver Lake, said doing preliminary tests earlier this year helped pinpoint issues.
“The primary problem we found had to do with the size of the screen on the iPad and the fact that the keyboard took up 40 percent of the screen,” Page said. 
The district then purchased keyboards for about $20 a piece. Hamilton High School principal Gary Garcia said many of the kinks have been worked out, but he still thinks there are better options.
“I have been lobbying the board of education and the district that, in the future, high school students should take this test on a laptop," he said.
The scores from the this year's state competency tests will not be released since the exams are considered part of the pilot rollout.  
In figures released today, the California Department of Education says its technical assistance center is taking an average of 722 calls a day from schools around the state.
And there's not much troubleshooting time left. Students at Los Angeles Unified have less than three weeks to log on and finish up.

Studies do indicate risks associated with exposure to electromagnetic frequency including leukemia and brain tumors. The simple fact is, we are currently the long-term test subjects of this new technology.
