Stem cells used to repair breast post cancer ops


London: British surgeons are using stem-cell-enriched fat from women’s bodies to repair the damage of surgery following breast cancer operations and radiotherapy.

The procedure, which is being trialled at Leeds General Infirmary, so far appears to restore the softness and suppleness of breast tissues, as well as the painful aftermath of treatments.

Each year around 31,000 British women undergo operations to remove cancerous tissue which normally leaves an unsightly cavity in the breast. Some surgeons have already used fat transfer to repair the damage as well as reducing the size of the other breast to match the damaged one.

Scientists believe that fat enriched with stem cells reduces inflammation and helps maintain a healthy blood supply so that the body’s repair system works more efficiently.

Fears that the stem-cells might encourage more cancer cell proliferation have also proved groundless.

The cancer patient’s own fat cells are harvested and made into a concentrate which is reinjected. More than 90% of the fat survives the process.

Lead investigator and consultant plastic surgeon Eva Weiler-Mithoff says she is impressed with the results so far. “What is striking is the softness and suppleness the technique gives the skin and tissues. When I see these stem-cell-enhanced patients after three months, their skin is significantly softer.”

Mobiles disrupt sleep, says new report


London: Mobile phones severely disrupt sleep patterns, according to scientific research into their impact on human rest, funded by the Mobile Manufacturers Association.

The research undertaken by the Electromagnetic Academy based at the Massachusetts Institute of Technology, in the United States, exposed 71 men and women, aged between 18 and 45, to mobile phone radiation as they prepared to sleep.

According to the study, monitoring under laboratory conditions showed the initial ‘light’ phases of sleep in the subjects were affected. In addition, “exposure to 884 MHz wireless signals, components of sleep, believed to be important for recovery from daily wear and tear, are adversely affected.”
The research also found that those exposed to mobile phones during their sleep appear to have more headaches, than those not exposed.

The findings coincide with calls from UK company Exradia, manufacturers of the first device proven to neutralize potentially dangerous mobile phone radiation, for more government research into the health issues being raised.

David Schick, Exradia chief executive, said, “This study is yet another example of how using mobile phones can have a detrimental effect on humans.
It is critical that the UK Government now undertakes a formal public inquiry into this issue.”

France recently became the latest country to advise against excessive use of mobile phones, particularly by children. Other countries who’ve issued similar advice include Sweden, the UK, Israel and India.

“The Effects of 884 MHz GSM Wireless Communication Signals on Self-reported Symptom and Sleep (EEG)” was sponsored by the Mobile Manufacturers Forum and published in the Progress in Electromagnetics Research Symposium (PIERS) from the US Electromagnetics Academy based at MIT in Cambridge USA. The research was undertaken by six scientists from the following Universities/bodies – Wayne State Univertisy & Uppsala University, USA; Karolinska Institutet, Sweden and Foundation IT’IS, USA.

The Exradia Angel™ www.exradia.comis a replacement battery containing a chip and coil that actively superimposes a random noise field over the radio waves emitted by the cellular antenna. The Angel costs £24.99 and is available for 80% of the popular mobile phones available today from Nokia, Motorola, Sony Ericsson, LG and Samsung.

Six leading American Universities, including Columbia University, New York, have independently tested the Angel technology in research between 1993 and 2005. All the studies confirmed that radiation emitted from mobile phones does cause biological changes in animals and that the Angel technology neutralized the changes in every case.
