Last week, three prominent neurosurgeons told the CNN interviewer Larry King that they did not hold cellphones next to their ears. "I think the safe practice," said Dr. Keith Black, a surgeon at Cedars-Sinai Medical Center in Los Angeles, "is to use an earpiece so you keep the microwave antenna away from your brain."
Dr. Vini Khurana, an associate professor of neurosurgery at the Australian National University who is an outspoken critic of cellphones, said: "I use it on the speaker-phone mode. I do not hold it to my ear." And CNN's chief medical correspondent, Dr. Sanjay Gupta, a neurosurgeon at Emory University Hospital, said that like Dr. Black he used an earpiece.

More than half of all older adults complain about having difficulties sleeping. Most don't bother seeking treatment. Those who do usually turn either to medications, which can lead to other health problems, or behavior therapies, which are costly and often not available close to home.
Now, UCLA researchers report that practicing tai chi chih, the Westernized version of a 2,000-year-old Chinese martial art, promotes sleep quality in older adults with moderate sleep complaints. The study, which will be published in the journal Sleep, is currently available in the journal's online edition.

A team led by Dr. Ji-Kun Li has determined that AMD3100, originally developed in acquired immune deficiency syndrome treatment, could markedly inhibit spreading of colorectal cancer cells by blocking a new pair of ligands and its unique receptor. This effect differs from the usual inhibition by a conventional chemotherapic agent that is more specific to cancer cells with high metastatic potential.
A team led by Professor Qing Xia at the West China Hospital of Sichuan University has determined the genetic treatment mechanism of Chaiqinchengqi decoction, which is a basic Chinese herbal compound commonly used in the treatment of acute pancreatitis. It can upregulate sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) mRNA expression of pancreatic tissue as well as inhibit the elevation of calcium concentration in pancreatic acinar cells while relieving pancreatic lesions in an acute pancreatitis model of rats.
Can Wyeth win back the 40 million Premarin and Prempro users it's lost since 2002--along with $1 billion a year in profits--with a new menopause drug? Or will the once-bitten women who have filed more than 5,000 law suits claiming the hormones gave them cancer feel fooled twice?
Pristiq, a serotonin/norepinephrine reuptake inhibitor (SNRI), is a metabolite of Wyeth's antidepressant Effexor XR--which netted $3.7 billion in 2006--and an unabashed patent extender since Effexor XR goes off patent in 2010.

Nearly a century after the discovery of strange star-shaped cells in the brain, scientists say they have finally begun to unravel their function.
Researchers from the Massachusetts Institute of Technology report in Science that it appears astrocytes - named for their stellar form - provide nerve cells (neurons) with the energy they need to function and communicate with one another, by signaling blood to deliver the cell fuels glucose and oxygen to them.
When astrocytes were first discovered, it was believed that they were bit players in the brain. But the new research indicates they may actually be major operators that, when out of whack, may help trigger mental disorders such as autism and schizophrenia.

Retrofitting women to make them sexually attractive and "marriageable" is more than a Hollywood fad. It's life or death for many.
By 2020, it is predicted that Africa will be facing a cancer epidemic. Claudia Hammond reports from Ghana, where efforts are being made to transform cancer care before it is too late.
Lichen sclerosis (LS) includes balanitis and xerotica obliterans. There is hyperkeratosis and sclerosis of the dermis with collagen deposition that leads to symptoms of skin irritation. It is much more common in women and also occurs in 10% of boys with phimosis. A larger study of boys more recently showed a 39% incidence with phimosis and circumcision cured almost all patients. In adults undergoing urethroplasty, 14% were found clinically, but in 82% by histology.
The threat of a global Aids epidemic is over, the World Health Organisation's top HIV expert has admitted.
Understanding of the threat posed by the virus had changed said Kevin De Cock, who has spent most of his career leading the battle against the disease.
Rather than being a risk to populations anywhere, the threat in developed countries is largely confined to gay men, drug addicts and prostitutes and their clients.

Comment: Note that though the titles are completely different, both articles basically say that even if there was some progress, there is still work to be done. What is then the reason behind the contrasting wording? Could it again be money and politics?
