Converting adult stem cells to embryonic-like stem cells

Converting adult stem cells to embryonic-like stem cells
The simple recipe researchers earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell, a Cell Press publication, shows for the first time that neural stem cells taken from adult mice can take on the characteristics of embryonic stem cells with the addition of a single transcription factor. Transcription factors are genes that control........Go to the Research news blog (Added on 2/6/2009 6:14:16 AM)


Alcohol advertising may lead to underage drinking

Alcohol advertising may lead to underage drinking
Alcohol advertising and marketing may lead to underage drinking. A large systematic review of more than 13,000 people, reported in the open access journal BMC Public Health, suggests that exposure to ads and product placements, even those supposedly not directed at young people, leads to increased alcohol consumption. Lesley Smith and David Foxcroft from Oxford Brookes University collated information from seven rigorously selected studies,........Go to the Society medical news blog (Added on 2/6/2009 6:09:02 AM)

Sleep apnea may be cured if you put effort to lose weight
For sufferers of obstructive sleep apnea (OSA), a newly released study shows that losing weight is perhaps the single most effective way to reduce OSA symptoms and associated disorders, as per a newly released study in the American Journal of Respiratory and Critical Care Medicine, one of the American Thoracic Society's three peer-evaluated journals.

Hormone Replacement therapy indicted again
Postmenopausal women who take combined estrogen plus progestin menopausal hormone treatment for at least five years double their annual risk of breast cancer, as per new analyses from a major study that clearly establishes a link between hormone use and breast cancer, Stanford scientists say. The multi-center study also observed that women on hormones can quickly reduce their risks of cancer simply by stopping the treatment.

How much screen time is enough for children with asthma?
Urban children with asthma engage in an average of an hour more of screen time daily than the maximum amount American Academy of Pediatrics (AAP) recommends. This is the first study to examine screen time among children with asthma.
