More sxxx for healthy living

BRASILIA - ONE of the best ways Brazilians can stave off chronic illness is to engage regularly in physical exercise, especially sxxx, Health Minister Jose Gomes Temporao said on Monday.

'People need to be active. A weekend football game must not be the only physical activity for a Brazilian. Adults need to do exercise: walk, dance and have safe sxxx,' he said.

The minister gave the advice as he launched a campaign to prevent high blood pressure, which afflicts a quarter of Brazil's 190-million strong population.

After making his comments, Mr Temporao reinforced the sxxx message with journalists, according to the G1 news website. 'It's not a joke. It's serious. Having regular physical exercises also means sxxx, always with protection of course,' he said.

'Dancing, having sxxx, keeping weight under control, changing dietary habits, doing physical exercise' all help keep blood pressure down, he said.

He added that he believed there was a health 'time bomb' ticking in Brazil, which within 20 years could see a 'gigantic percentage' of the population suffering chronic illnesses, high blood pressure, diabetes and high cholesterol. -- AFP

New hope for ovarian cancer

VIENNA - AUSTRIAN researchers have found an antibody that could be used to step up the fight against ovarian cancer - a major killer for women.

The AD5-10 antibody helps to weaken the resistance of cancer cells in the body's immune system, according to the University of Vienna researchers whose work was published on Monday.

The antibody reduced the resistance of tumour cells to a natural resistance mechanism known as Tumour Necrosis Factor Related Apoptosis Inducing Ligand (TRAIL). The TRAIL protein induces cancerous cells to commit suicide.

Some of the tumour cells fail to react to the suicide signal however, making ovarian cancer the most fatal form of disease affecting the female sexual and reproductive organs. The American Cancer Society estimates that about 21,550 new cases of ovarian cancer were diagnosed in the United States in 2009. The Austrian team's work offers new hope of improved treatment.

'We were able to show in both cell cultures and animal models that TRAIL resistant ovarian cancer tumour cells become sensitive to TRAIL again if TRAIL and AD5-10 are both present at the same time,' said Michael Krainer, who led study at the university's Faculty of Medicine.

The AD5-10 antibody attaches itself to a different part of the cancer cell than the TRAIL protein, which could explain its effect, said the Austrian team. -- AFP
