Healthy lifestyle helps body's cells fight ageing: Scientists

Scientists says strategy is structured around a whole-food‚ plant-based diet‚ moderate daily exercise‚ yoga-based relaxation.

Scientists said that they had proof

 that a healthy lifestyle helps the 

body's cells fight ageing.

They said that the strategy is 

structured around a whole-food‚

 plant-based diet‚ moderate daily

 exercise‚ yoga-based relaxation

 and stress management.

The researcher said that the 

implications of this relatively 

small pilot study may go beyond 

men with prostate cancer.

If validated by large-scale 

randomized controlled trials‚ these comprehensive lifestyle changes may significantly reduce the

 risk of a wide variety of diseases and premature mortality.

Sleep boosts brain cell numbers

Sleep boosts brain cell numbers

In contrast‚ the genes involved in cell death and stress 

responses were turned on when the mice were forced to 

stay awake.

Scientists believe that

 they have discovered 

a new reason why we 

need to sleep it replenishes

 a type of brain cell.

Dr Chiara Cirelli and 

colleagues from the 

University of Wisconsin

 found that the production

 rate of the myelin making

 cells‚ immature 

oligodendrocytes‚ doubled

 as mice slept.

The increase was most marked during the type of sleep that is associated with 

dreaming - REM or rapid eye movement sleep - and was driven by genes.

In contrast‚ the genes involved in cell death and stress responses were turned on when the

 mice were forced to stay awake.

Dr Cirelli said that for a long time‚ sleep researchers focused on how the activity of nerve 

cells differs when animals are awake versus when they are asleep.

Green tea extract kills childhood cancers

Green tea extract kills childhood cancers

Cancer researcher says a modified antioxidant called catechin can kill 

50 per cent of cells from neuroblastoma cancers within 3 days in 

laboratory studies.

A green-tea extract could help
destroy deadly childhood cancers
that are resistant to traditional
chemotherapy.

Cancer researcher Orazio Vittorio
said that a modified antioxidant
called catechin

 can kill 50 per cent of the cells from
neuroblastoma cancers within 3 days in 

laboratory studies.

Neuroblastoma is the most common
 cancer to strike infants‚ and has the
lowest

 survival rate of all childhood cancers.

Catechin‚ extracted from green tea‚ is thought to be a promising cancer treatment‚ but its instability
when it enters the body limits its effectiveness.

Dr Vittorio‚ from the Children's Cancer Institute Australia and the Lowy cancer research center at
UNSW said that the modified form of catechin is effective at destroying neuroblastoma cells that are
highly resistant to conventional chemotherapy.
