How to enhance nonthermal effects of ultrasound

High-intensity focused ultrasound is a rapidly developing noninvasive technology for tumor treatment. A research group in China investigated the pathological characteristics of nonthermal damage induced by pulsed high intensity focused ultrasound (PHIFU) combined with ultrasound contrast agent (UCA) in rabbit liver VX2 tumor. The results showed that non-thermal effects of PHIFU combined with UCA could be used to treat tumor. And this would provide a new method of therapy for tumor.

Scientists have new information about the complex genetic signature associated with Alzheimer’s disease, the leading cause of cognitive decline and dementia in the elderly. The research, published by Cell Press in the January issue of the American Journal of Human Genetics, uses a powerful, high-resolution analysis to look for genes associated with this devastating neurodegenerative disorder.

Smokers with stroke in the family 6 times more likely to have stroke too

A new study shows that people who are smokers and have a family history of brain aneurysm appear to be significantly more likely to suffer a stroke from a brain aneurysm themselves. The research is published in the Dec. 31, 2008, online issue of Neurology, the medical journal of the American Academy of Neurology, and will appear in the Jan. 6, 2009, print issue of Neurology.
