Cell phone radiation reverses Alzheimer’s

Radiations emitted from cell phones may protect against and even reverse Alzheimer’s disease, a new study has revealed.

Researchers at the University of South Florida conducted a study that exposed 96 mice, most of whom had been genetically altered to develop the Alzheimer’s disease as they aged, to electromagnetic waves generated by mobile phones.

The mice were zapped with 918MHz of frequency twice a day for one hour each time over a period of seven to nine months. The study revealed that in older mice with Alzheimer’s, long-standing exposure to the electromagnetic fields caused deposits in the brain of beta-amyloid, a protein fragment that accumulates in the brain of Alzheimer’s sufferers to form the disease’s signature plaques, to be erased.  Memory impairment in the older mice also vanished, the study showed.

Young adult mice with no apparent signs of memory impairment were protected against Alzheimer’s disease after several months of exposure to the mobile phone waves.
And the memory levels of normal mice with no genetic inclination for Alzheimer’s disease were enhanced after exposure to the electromagnetic waves. Based on the findings in mice, the researchers anticipate that electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and cure Alzheimer’s.

Drug reverses age-related changes in brain

A new study has found that drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging.
Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses in brain regions critical to learning and memory, such as the hippocampus.

In the current study, Cui-Wei Xie, PhD, of the University of California, found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) — a protein that promotes synaptic plasticity — and less histone acetylation of the Bdnf gene.

By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals. “These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging,” said Xie, who led the study.

Mindful eating may help curb weight gain

Mastering simple mindful eating and stress-reduction techniques could help prevent weight gain even without dieting, according to a new study.

UCSF researchers found that women in the study who experienced the greatest reduction in stress tended to have the most loss of deep belly fat. “You’re training the mind to notice, but to not automatically react based on habitual patterns – to not reach for a candy bar in response to feeling anger, for example,” said UCSF researcher Jennifer Daubenmier, PhD, from the Osher Center for Integrative Medicine.

“If you can first recognize what you are feeling before you act, you have a greater chance of making a wiser decision,” she stated.

The women who participated in the study were not on calorie-counting diets. Instead, 24 of the 47 chronically stressed, overweight and obese women were randomly assigned to mindfulness training and practice, and the other 23 served as a control group. Although no diets were prescribed, all participants attended one session about the basics of healthy eating and exercise.

The training included nine weekly sessions, each lasting 2 1/2 hours, during which the women learned stress reduction techniques and how to be more aware of their eating by recognizing bodily sensations – including hunger, fullness and taste satisfaction. At week six they attended an intensive seven-hour, silent meditation retreat.

Those who had greater improvements in listening to their bodies’ cues, or greater reductions in stress or cortisol, experienced the greatest reductions in abdominal fat.
