(Press-News.org) Los Angeles, CA (April 23, 2012) The benefits of breast milk are well known, but why breastfeeding protects against various forms of cancer remains a mystery. A new study in the Journal of Human Lactation (published by SAGE) found high levels of cancer-fighting TNF-related apoptosis inducing ligand (TRAIL) in human milk, which might be one source of breast milk's anticancer activity.
Researchers took samples of colostrum, the first milk available to newborns, and of mature breast milk from new mothers. Researchers then obtained samples of blood from healthy women, and various ready-to-feed infant formulas. The colostrum, mature breast milk, blood and formula were then all tested to measure their level of TRAIL. The researchers found that colostrum and breast milk contained 400- and 100-fold, respectively, higher levels of TRAIL than blood. No TRAIL was detected in the formula.
"The important role of breastfeeding in the prevention of cer¬tain childhood cancers, such as lymphoblastic leukemia, Hodgkin's disease, and neuroblastoma, has been previously demonstrated," wrote the authors. "However, endogenous soluble TRAIL represents a strong candidate to explain the overall biological effect of breastfeeding against cancer."
Mothers chosen to participate in the study were eligible because they exhibited no signs of eclampsia, infection, or fever, and delivered healthy newborns at term.
The authors wrote, "To our knowledge, this is the first time that TRAIL has been measured in colostrum and human breast milk. This study has revealed much higher TRAIL concentrations in colos¬trum and breast milk compared to the levels of circulating serum TRAIL."

When a plant goes into defense mode in order to protect itself against harsh weather or disease, that's good for the plant, but bad for the farmer growing the plant. Bad because when a plant acts to defend itself, it turns off its growth mechanism.
But now researchers at Michigan State University, as part of an international collaboration, have figured out how plants can make the "decision" between growth and defense, a finding that could help them strike a balance – keep safe from harm while continuing to grow.
Writing in the current issue of the Proceedings of the ...
The annual cost of running your car is higher in Queensland than both NSW and Victoria, according to the new Bingle Cost of Motoring Index launched today.
Bingle spokesperson Melanie Vine said the reason for this is petrol, as the average cost is higher and Queenslanders cover more ground.
"On average, Queenslanders pay $411 more for petrol each year compared to New South Wales drivers," she said.
"Before you add petrol, Queenslanders pay less for fines, parking and tolls compared to Victorians, or NSW drivers' generally higher rego, maintenance ...
Ten years ago, a landmark clinical trial in Canada demonstrated the unequivocal effectiveness of brain surgeries for treating uncontrolled epilepsy, but since then the procedure has not been widely adopted—in fact, it is dramatically underutilized according to a new study from the University of California, San Francisco (UCSF).
The study, published this month in the journal Neurology, showed that the number of Americans having the surgery has not changed in the decade since release of the effectiveness study, though surgical treatment is now uniformly encouraged by neurology ...
Copenhagen Zoo and University of Copenhagen have in collaboration developed a new and revolutionary, yet simple and cheap, method for tracking mammals in the rainforests of Southeast Asia. They collect leeches from tropical jungles, which have been sucking blood from mammals, and subsequently analyse the blood for mammal DNA. By using this method, the researchers can get an overview of the biodiversity of the mammals without having to find them. The groundbreaking results are to be published in the prestigious scientific journal Current Biology.
"It is not unusual that ...
SAN DIEGO—Obstructive sleep apnea (OSA) is a disorder in which there are recurring episodes of upper airway collapse during sleep with ongoing effort to breathe. OSA is estimated to affect 1 in 5 adults in America. The serious nature of the problem was captured in a landmark study which found that middle-age and older men with even mild levels of OSA were in danger of increased risk of stroke and death. While a link between OSA and stroke is clear, OSA's effect on the cerebral (brain) vessels is not. In an effort to shed light on this relationship, researchers in Texas ...
Scientists at Aarhus University have spearheaded research results that shed new light on the processes forming the composition of species assemblages in the tropics.
"It comes as a surprise to us that climate change over millions of years still leaves a signature in the composition of species assemblages we see today. If species are severely affected by current and future climate change, it'll mean that there are long-lasting consequences for biodiversity, maybe over many millions of years to come – at least much longer than we've ever dreamt of before," says Daniel Kissling, ...
Periodic outbreaks of bark beetles can cause annual losses of millions of dollars and pose serious challenges for forest managers, and the suppression of outbreaks is particularly difficult and expensive.
According to T. D. Schowalter, author of a new open-access article in the Journal of Integrated Pest Management called "Ecology and Management of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern Pine Forests," preventative measures are most effective in minimizing losses to these beetles, and several factors should be considered in planning bark beetle ...
A team of scientists from Johns Hopkins and elsewhere have developed nano-devices that successfully cross the brain-blood barrier and deliver a drug that tames brain-damaging inflammation in rabbits with cerebral palsy.
A report on the experiments, conducted at Wayne State University in collaboration with the Perinatology Research Branch of the National Institute of Child Health and Human Development, before the lead and senior investigators moved to Johns Hopkins, is published in the April 18 issue of Science Translational Medicine.
For the study, researchers used ...
