Genetic markers for fetal overgrowth syndrome discovered

Research could lead to safer, more efficient assisted reproduction procedures

2015-04-28
(Press-News.org) Humans and cattle share a similar epigenetic fetal overgrowth disorder that occurs more commonly following assisted reproduction procedures. In humans, this disorder is called Beckwith-Wiedemann syndrome (BWS), and in cattle it is called large offspring syndrome (LOS) and can result in the overgrowth of fetuses and enlarged babies. This naturally occurring, but rare syndrome can cause physical abnormalities in humans and cattle and often results in the deaths of newborn calves and birth-related injuries to their mothers.

Now, researchers at the University of Missouri have identified a number of genes that contribute to LOS in cattle. Rocío Melissa Rivera, an associate professor in the MU College of Agriculture, Food and Natural Resources, says identifying these genes in cattle will help identify genes that cause BWS in humans.

"The human disorder BWS is physically and molecularly very similar to LOS in cattle," Rivera said. "By identifying the LOS genes, we can take steps toward discovering which genes cause BWS in humans. Because these disorders have been associated with pregnancies from in vitro fertilization, knowing which genes cause these disorders will allow doctors to choose embryos for implantation that do not have the molecular markers for BWS."

Beckwith-Wiedmann syndrome results in babies that grow and gain weight more rapidly than normal in the womb and throughout early childhood. Many children with BWS have enlarged tongues, abdominal wall defects, asymmetric growth where some body parts grow faster than others, and are at a higher risk for cancer throughout childhood. BWS, other than the most severe cases, is not fatal to humans unless they develop undetected cancer.

Large offspring syndrome in cattle has many similar characteristics to BWS in humans, including rapid growth, weight gain in the womb, large tongues and abdominal wall defects. Calves with LOS can die within a week of birth because many cannot support their own weight and size.

"The use of in vitro fertilization is common in cattle breeding, so LOS is a potential problem those breeders face," Rivera said. "It is important for breeders to be able to identify the genetic causes of LOS so they can avoid impregnating their cattle with embryos that are predisposed to the disorder. This will allow the breeding process to be much more efficient as well as safe for the cattle being bred."

Rivera's study was published in the Proceedings of the National Academy of Sciences (PNAS).

Study shows diversity of habitat needed around spotted owl reserves

2015-04-28
CHESTER, Calif. - A study just published this week shows many bird species, including several of high conservation concern, aren't getting the habitat they need due to a focus on promoting California Spotted Owl habitat in the northern Sierra Nevada. The study, published in the science journal, PLoS ONE, tracked different bird species' use of areas inside and outside Spotted Owl reserves for two years in Plumas and Lassen National Forests. The results show 17 species avoided the reserves, including species of conservation concern like Yellow Warblers and Olive-sided ...

Emergency department treatment for opioid addiction better than referrals

2015-04-28
New Haven, Conn. -- Yale researchers conducted the first known randomized trial comparing three treatment strategies for opioid-dependent patients receiving emergency care. They found that patients given the medication buprenorphine were more likely to engage in addiction treatment and reduce their illicit opioid use. Dependence on prescription and illicit opioids is an epidemic that continues to grow in the United States and globally. Drug overdoses account for more deaths each day than car crashes. "This is a huge public health problem," said first author Dr. Gail D'Onofrio, ...

WASHINGTON, DC, April 28, 2015 -- The secret desire of urban daydreamers staring out their office windows at the sad brick walls of the building opposite them may soon be answered thanks to transparent light shutters developed by a group of researchers at Pusan National University in South Korea. A novel liquid crystal technology allows displays to flip between transparent and opaque states -- hypothetically letting you switch your view in less than a millisecond from urban decay to the Chesapeake Bay. Their work appears this week in the journal AIP Advances, from AIP ...

New IVF device may improve fertility treatment
2015-04-28
WASHINGTON, D.C., April 28, 2015--For couples struggling to conceive the old-fashioned way, in vitro fertilization (IVF) provides an alternate route to starting a family. When eggs are mixed with sperm in test tubes, the fertilized eggs to grow into embryos that can be implanted inside the uterus of a woman who will carry them to term. IVF often works miracles for infertile couples, a fact for which its inventor won a Nobel Prize a few years ago. However, the procedure can be time-consuming, costly, and emotionally draining, often requiring multiple implantation cycles ...

Tracking exploding lithium-ion batteries in real-time

2015-04-28
What happens when lithium-ion batteries overheat and explode has been tracked inside and out for the first time by a UCL-led team using sophisticated 3D imaging. Understanding how Li-ion batteries fail and potentially cause a dangerous chain reaction of events is important for improving their design to make them safer to use and transport, say the scientists behind the study. Hundreds of millions of these rechargeable batteries are manufactured and transported each year as they are integral to modern living, powering mobile phones, laptops, cars and planes. Although ...

Scientists discover salty aquifer, previously unknown microbial habitat under Antarctica

Scientists discover salty aquifer, previously unknown microbial habitat under Antarctica
2015-04-28
HANOVER, N.H. - Using an airborne imaging system for the first time in Antarctica, scientists have discovered a vast network of unfrozen salty groundwater that may support previously unknown microbial life deep under the coldest, driest desert on our planet. The findings shed new light on ancient climate change on Earth and provide strong evidence that a similar briny aquifer could support microscopic life on Mars. The study appears in the journal Nature Communications. It is available through open access. A PDF of the study, photos and video also are available on request. ...

Two-week international diet swap shows potential effects of food on colon cancer risk

PITTSBURGH, April 28, 2015 - African-Americans and Africans who swapped their typical diets for just two weeks similarly exchanged their respective risks of colon cancer as reflected by alterations of their gut bacteria, according to an international study led by researchers at the University of Pittsburgh School of Medicine published online today in Nature Communications. Principal investigator Stephen O'Keefe, M.D., professor of medicine, Division of Gastroenterology, Hepatology and Nutrition, Pitt School of Medicine, observed while practicing in South Africa that his ...

KNOXVILLE--Many view Antarctica as a frozen wasteland. Turns out there are hidden interconnected lakes underneath its dry valleys that could sustain life and shed light on ancient climate change. Jill Mikucki, a University of Tennessee, Knoxville, microbiology assistant professor, was part of a team that detected extensive salty groundwater networks in Antarctica using a novel airborne electromagnetic mapping sensor system called SkyTEM. The research, funded by the National Science Foundation, provides compelling evidence that the underground lakes and brine-saturated ...

Small high school reform boosts districtwide outcomes

2015-04-28
Creating small high schools improves outcomes for students in the overall school district - both in new small schools and existing larger schools - according to a study of New York City schools by researchers at New York University, Syracuse University, and Arizona State University. The findings, published in the April issue of Educational Researcher, help to answer questions of whether introducing small high schools comes at an expense to the rest of the school district. "Our findings suggest that there was real, meaningful improvement in New York City's high school ...
