The Cancer Rumour mill working over time

... floor cleaners, cell-phones, microwave ovens, and electrical blankets when they read stories attributed to phony medical journals listing these products as potential cancer causers. However, medical experts are concerned that people believe such myths yet ignore research that clearly shows that some substance...

Shock it to Heal!!

...gh voltage electric current to the skin. //Such an electrical stimulation would help in the healing of foot ulcers. People with diabetes may develop foot ulcers as a result of poor circulation and a reduced ability to fight infection. The conventional way to treat such ulcers would be by cleaning and daily dre...

Air pollution affects the heart

... the blood vessels, blood pressure and the heart's electrical activity. The fact that air pollution appears to be linked with a decrease in heart rate variability shows that it has an adverse impact on the heart....

Need to use defibrillators

... is taken to restart the heart, using an automated electrical defibrillator (AED), a device which delivers an electric shock to the heart muscle. There are moves to put more AED's in public places, like shopping malls, and to train staff to use them. But most cardiac arrests occur in the home. Researchers in ...

Acupuncture can ease cancer

...g needles, but then passing different strengths of electrical current through them.The latest study to back the technique was carried out at the National Institutes of Health in Maryland, US, and reported in the Journal of the American Medical Association. Thirtyeight patients were given electroacupuncture th...

Depression disturbs heart rate

...t attack. HRV measures the nervous functioning - electrical wiring, if you like - of the heart. It influences blood vessel size, blood pressure and the heart's ability to contract. A healthy heart is one with a high HRV. The fact that depression lowers HRV points to an important mind-body mechanism. Clearly, ...

New treatment for depression

...octors on an anti-depression 'pacemaker' found the electrical device can significantly improve the mental health of patients.// The pacemaker, which is implanted in a person's chest, sends intermittent signals to the left vagus nerve in the brain. The device was originally used to treat patients with epilepsy...

Exposure to EMF may cause leukemia

...e pollutants such as exhaust fumes, giving them an electrical charge and making them more likely to be deposited in the lungs when inhaled. ICNIRP sets international guidelines for protection against the electromagnetic fields associated with the transmission, generation and use of electricity.The new study is ...

Microchip gives blind a chance of sight

FDA approves first pocket-sized EKG machine

...called EKGs or ECGs, are recordings of the heart's electrical signals, used to diagnose heart attacks, irregular heartbeats and other cardiac problems.// The new PocketView ECG works just as well as full-size electrocardiograph machines, the Food and Drug Administration determined - but is the size of a handhel...
