| WASHINGTON (Reuters) – Tobacco plants might yield a cheap and easy-to-administer vaccine against a pesky stomach virus called norovirus, U.S. researchers reported on Tuesday.
They found a way to make tobacco produce a protein that can be used to make a nasal vaccine against norovirus, which causes diarrhea and vomiting, especially on cruise ships, in restaurants, schools and on military bases. |

| LONDON (Reuters) – Chemicals in cannabis have been found to stop prostate cancer cells from growing in the laboratory, suggesting that cannabis-based medicines could one day help fight the disease, scientists said Wednesday.
After working initially with human cancer cell lines, Ines Diaz-Laviada and colleagues from the University of Alcala in Madrid also tested one compound on mice and discovered it produced a significant reduction in tumor growth. |

| LONDON – Treating advanced prostate cancer with radiation and hormone-blocking drugs cut the death rate in half in a study of Scandinavian men, researchers report. In the United States, the combination has been standard care since the 1990s. But in Europe, many doctors have avoided the combo treatment and used hormone drugs alone, thinking the pair would be too harsh for most patients. |

| Certain breast cancer survivors who load up on fruits and vegetables, eating far more than current U.S. guidelines, can slash their risk the tumors will come back by nearly a third, according to a U.S. study released on Monday.
The finding only held for women who did not have hot flashes after their cancer therapy, the researchers said -- a finding that suggests fruits and vegetables act on estrogen. |

Those with the worst sleep apnoea symptoms burned 373 extra calories a day compared with those with only mild symptoms, US researchers found.
Nervous system changes triggered by the condition may be responsible. |

The pivotal trial of the test developed by privately held German company Brahms AG succeeded in its goal of demonstrating superiority over tests considered the current gold standard. |

| The neck arteries of obese children and teenagers experience similar strain as those of middle-aged adults, US researchers said Tuesday.
"There's a saying that 'you're as old as your arteries,' meaning that the state of your arteries is more important than your actual age in the evolution of heart disease and stroke," said Geetha Raghuveer, professor of pediatrics at the University of Missouri School of Medicine and cardiologist at Children's Mercy Hospital, Kansas City, Kansas. |

| Pregnancy has long been blamed for addling women's minds but new work by Australian researchers finds this idea may be nothing more than an old wives' tale.
A study by the Australian National University's centre for mental health research found that there is no evidence to suggest that impending motherhood affects a woman's cognitive ability.
The research is based on analysis of interviews with 2,500 women aged between 20 and 24 first undertaken in 1999 and again later in 2003 and 2007. |

| A German farmer who received the world's first complete double arm transplant said Wednesday that incredulity gave way to joy when he woke from surgery to discover he had arms again. Karl Merk, who lost his arms in a farming accident six years ago, said he at first could not believe that the transplant appeared to have been succesful.
"It was really overwhelming when I saw that I had arms again," said the 54-year-old, who wore a sleeveless black shirt showing clearly where his new arms had been grafted. |

| Scientists in Japan have identified a genetic mutation linked to narcolepsy, a disease that can cause someone to doze off in mid-sentence or behind the wheel of a car, a study released Sunday reports.
Other symptoms of the condition, which shows up in late adolescence or early adulthood, include excessive daytime drowsiness, vivid hallucinations on the threshold of sleep, and the sudden, temporary loss of muscle control, often triggered by emotional shock. |

An analysis of 17 clinical trials involving 4,783 patients with chronic obstructive pulmonary disease (COPD) revealed the adverse cardiovascular outcomes for those using inhaled anticholinergics as opposed to a placebo or some other kind of treatment. |

Introducing fish of any type into the diet curbed the risk of contracting the skin condition by 25 percent compared with children who never ate it, Bernt Alm, a pediatrician at the University of Gothenburg in Sweden, and colleagues reported in the British Medical Journal.

The world is expected to be extremely short of vaccines in the event of a flu pandemic, so the search for the best way to deliver vaccines is important because it would economize on the quantity of each dose.

Muscles and receptors in the mouth and throat retain a memory of their position and feeling when a word is uttered, and their signals provide key input for the brain as it hones the power of speech, they suggest. |

"It's a silent killer. It's hard to diagnose," said acting Surgeon General Dr. Steven Galson, who announced the new campaign Monday. "I don't think most people understand that this is a serious medical problem or what can be done to prevent it." |

The findings implicate CDK8, a protein that regulates gene expression in the proliferation of colorectal cancer, the researchers found.
Should the results be validated, they could lead to new therapeutic approaches for colon cancer, as well as new screening and chemopreventative strategies, said Dr. Durado Brooks, director of prostate and colorectal cancer at the American Cancer Society. |

The stress is rooted in poverty and can be brought on by money woes, work loads, insufficient health insurance and other factors, said Craig Gundersen of the University of Illinois, who led the study. |
