New York, Oct 3: Women who consume fish during pregnancy are just as likley to protect their offspring from developing asthma as those who consume fish oil supplements, suggests a new study.

Pregnant women who consume high doses of omega-3 fatty acids in the third trimester may help protect their kids from developing breathing problems in their early childhood, according to the study.

“With almost equal to slightly higher cost, consuming 8-12 ounces (2-3 servings) of fish with low mercury levels a week not only may attain the same asthma protection, but also strengthen the nutritional benefits to infant growth and development,” said Richard Lockey, Professor at the University of South Florida in the US.

The study, published in the Journal of Allergy and Clinical Immunology: In Practice, was conducted in three groups of women in their third trimester.

The first group consumed omega-3 fatty acids from fish oil daily while the second group took a placebo. The third group was named the “no oil” group who were allowed to consume either fish or fish oil supplements as per their choices.

The researchers found that the children in the fish oil and the “no oil” groups took less asthma medication as they aged to 24 years old, inferring both groups developed less asthma.

“Omega-3 fatty acids cannot be synthesised by humans and therefore are essential nutrients which are derived exclusively from marine sources,” said iChen Hsing Lin from the University of South Florida.(IANS)

  • Researchers have found a new drug that may eventually help to reduce alcohol addiction in adults who used to binge during their adolescent years.

A new drug found which can reduce Alcohol addiction in teenagers

“During our teen years, the brain is still in a relatively immature state. Binge drinking worsens this situation, as alcohol undermines the normal developmental processes that affect how our brain matures,” said lead author Jon Jacobsen, a Ph.D. student at the University of Adelaide, Australia.

“Therefore, when an adolescent who has been binge drinking becomes an adult, they’re often left with an immature brain, which assists in the development of alcohol dependence,” Jacobsen added.

For the study, published in the Journal Neuropharmacology, researchers observed that adolescent mice involved in binge drinking behavior developed an increased sensitivity to alcohol as adults and engaged in further binge drinking.

The researchers were able to prevent some of these detrimental behaviors observed in adulthood, by giving mice a drug that blocks a specific response from the immune system in the brain.

The drug is (+)-Naltrexone, known to block the immune receptor Toll-like receptor 4 (TLR4).

“This drug effectively switched off the impulse in mice to binge drink. The mice were given this drug still sought out alcohol, but their level of drinking was greatly reduced,” says senior author Professor Mark Hutchinson, Director of the ARC Centre of Excellence for Nanoscale BioPhotonics at the University of Adelaide.

“We’re excited by the finding that we can potentially block binge drinking in an adult after they have experienced such behavior during adolescence, by stopping the activation of the brain’s immune system. It’s the first time this has been shown and gives us hope that our work has implications for the eventual treatment of alcohol addiction in adults,” Hutchinson noted.(IANS)
