Genetic predisposition for childhood asthma

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)

Computers to fight emerging infections

Computers to fight emerging infections
Computer analysis of existing drugs may be key to fighting new infectious agents and antibiotic-resistant pathogens like deadly tuberculosis strains and staph superbugs. Scientists in Canada say the use of such emergency discovery technology could save time, money and lives during a sudden outbreak or a bioterrorism attack. They reported here today at the 234th national meeting of the American Chemical Society. Drug repurposing or........Go to the Infectious disease blog (Added on 8/20/2007 7:50:23 AM)

Finding that 1-in-a-billion that could lead to disease
Errors 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 delayed

Umbilical cord clamping should be delayed
Clamping 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. ........Go to the OBGYN news blog (Added on 8/16/2007 9:24:54 PM)

Cardio Exercise Benefits In Male Vs. Female Hearts
While cardiovascular disease occurs in both men and women, it does not affect them in the same way. Risk factors and protective factors for heart diseases are likewise unequal. The molecular mechanisms responsible for these differences are so far unknown, but some believe it is due to chromosomal linked genes or sexual hormones such as estrogen and testosterone.
