Genetic predisposition for childhood asthma
Children who carry variations in specific genes that metabolize vehicle emissions are more susceptible to developing asthma, especially if they live near major roadways, a study led by scientists at the University of Southern California (USC) suggests.
Scientists observed that children who carried variations in two genes and lived within 75 meters of a major road were up to nine times more likely to develop asthma than children who lived........Go to the Allergy news blog (Added on 8/20/2007 9:33:53 PM)

Finding that 1-in-a-billion that could lead to diseaseErrors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. Now, researchers at Johns Hopkins have uncovered how the tiny protein-machines in cells tasked to search for such potentially life-threatening genetic damage actually recognize DNA errors.
Appearing online next week in Nature, the Hopkins team describes how the........Go to the Research news blog (Added on 8/19/2007 7:54:59 PM)
Umbilical cord clamping should be delayedClamping and cutting of the umbilical cord should be delayed for three minutes after birth, especially for pre-term infants, suggests a senior doctor in this weeks BMJ.
Early clamping and cutting of the umbilical cord is widely practised as part of the management of labour, but recent studies suggest that it may be harmful to the baby. The rate of early cord clamping varies widely in Europe, from 17% of units in Denmark to 90% in France.
