Patients with sickle cell disease rely more on the emergency room as they move from pediatric to adult health care, according to researchers at Washington University School of Medicine in St. Louis. An analysis of Medicaid data of more than 3,200 patients with sickle cell disease shows that emergency room visits tripled from age 15 to age 24. The research is reported Dec. 10 at the American Society of Hematology's annual meeting, in Atlanta. "There seems to be a breakdown in medical care during the transition from childhood to adulthood," says hematologist Morey A. ...

(ATLANTA, December 10, 2012) – Research unveiling key gaps in continuity of care for sickle cell patients transitioning from pediatric to adult care will be presented this week during the 54th Annual Meeting of the American Society of Hematology (ASH). Sickle cell disease (SCD) is an inherited, chronic blood disorder affecting between 90,000 and 100,000 Americans. Instead of producing healthy red blood cells, individuals with the disease produce abnormal, sickle-shaped cells that cannot easily move through blood vessels and deliver adequate oxygen to the body's tissues ...

BOSTON – December 10, 2012 – Joslin Diabetes Center scientists have demonstrated that brown adipose tissue (BAT) has beneficial effects on glucose tolerance, body weight and metabolism. The findings, which may lead to new treatments for diabetes, appear in the upcoming issue of the Journal of Clinical Investigation. Unlike the more prevalent white adipose tissue (WAT or white fat) which stores fat, BAT (or brown fat) burns fat to produce heat. Studies in mice and humans have suggested that BAT also plays a role in regulating body weight and metabolism. This has made ...

Josh Miller likes to call himself a conservation paleobiologist. The label makes sense when he explains how he uses bones as up-to-last-season information on contemporary animal populations. Bones, he says, provide baseline ecological data on animals complementary to aerial counts, adding a historical component to live observation. In his November cover article for the Ecological Society of America's journal Ecology, he assesses elk habitat use in Yellowstone National Park by their bones and antlers, testing his method against several decades of the Park Service's meticulous ...

A new oral agent under review by the U.S. Food and Drug Administration (FDA) is safe and effective in treating relapsed and treatment-resistant multiple myeloma, according to a multicenter, Phase II study presented by Mount Sinai School of Medicine researchers at the American Society of Hematology (ASH) Annual Meeting. The meeting is taking place December 8-11, 2012 in Atlanta.

We all perhaps know the feeling of mental exhaustion, but what does it mean physiologically to have mental fatigue? A new study carried out using brain scans could help scientists uncover the neurobiological mechanisms underlying mental fatigue. According to Bui Ha Duc and Xiaoping Li of the National University of Singapore writing in a forthcoming issue of the International Journal Computer Applications in Technology, mental fatigue has become commonplace as many people face increasing mental demands from stressful jobs, longer working hours with less time to relax and ...

A study conducted by researchers at the University of Granada Group of Neuropsychology and Clinical Psychoneuroimmunology has demonstrated that cortisol levels in saliva are associated with a person's ability to make good decisions in stressful situations. To perform this study, the researchers exposed the participants (all women) to a stressful situation by using sophisticated virtual reality technology. The study revealed that people who are not skilled in decision-making have lower baseline cortisol levels in saliva as compared to skilled people. Cortisol –known ...

Experiments at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have revealed a potential new way to attack common stomach bacteria that cause ulcers and significantly increase the odds of developing stomach cancer. The breakthrough, made using powerful X-rays from SLAC's Stanford Synchrotron Radiation Lightsource (SSRL), was the culmination of five years of research into the bacterium Helicobacter pylori, which is so tough it can live in strong stomach acid. At least half the world's population carries H. pylori and hundreds of millions suffer ...

At this time of year it is hard to escape the Three Wise Men, riding their camels across Christmas cards and appearing in minature form in countless school nativity plays across the world, bearing their gifts for the infant Jesus. Whilst we are all familiar with gold (especialliy in this Olympic year), it is the mention of frankincense and myrrh that really says "Christmas" to us and and takes our imaginations back to ancient times. But you might be surprised to learn that these two fragrances are still big business today; for example, Ethiopia alone trades around 4000 ...

Philadelphia, PA, December 10, 2012 – A large body of research has focused on the ability of oxytocin to facilitate social bonding in both marital and parenting relationships in human females. A new laboratory study, led by Dr. Ruth Feldman from Bar-Ilan University in Israel and published in the current issue of Biological Psychiatry, has found that oxytocin administration to fathers increases their parental engagement, with parallel effects observed in their infants. Oxytocin is a neuropeptide that plays an important role in the formation of attachment bonds. Studies ...

Biotechnologists Rahul Negi, Gouri Satpathy, Yogesh Tyagi and Rajinder Gupta of the GGS Indraprastha University in Delhi, India, explain how waste from the processing and canning of onion (Allium cepa L.) and garlic (Allium sativum L.) could be used as an alternative remediation material for removing ...

A system that uses ultrasound technology to look inside car engines could lead to more efficient engines – and huge fuel savings for motorists. Ultrasound scans have long been a fundamental tool in healthcare for looking inside the human body, but they have never before been put to use in testing the health of a modern combustion engine. In the University of Sheffield's Department of Mechanical Engineering, Rob Dwyer-Joyce, Professor of Lubrication Engineering, has devised a method of using ultrasound to measure how efficiently an engine's pistons are moving up and ...

ANN ARBOR, Mich. — As we get older, the trillions of cells in our body do too. And like us, they become less resilient and able to weather the stress of everyday life. Our skin especially tells the tale of what's happening throughout our bodies. But recently, scientists have learned that aging cells bear only part of the blame for this downward spiral. And a new study shows that it might be possible to slow the decline of aging tissue – and even make it act younger -- by focusing on the stuff that surrounds those cells. In an independent study at the University of Michigan ...

A study at the Jaume I University in Castellón has verified the decrease in press consumption among young people between the ages of 16 and 30 years, which now stands at 28.8%. What is more, three out of every four individuals within this age bracket use social networking sites more than the television to get up to date. News consumption habits among young people have changed radically in recent years. Since the beginning of the 21st century, various studies have indicated a decrease in readership of printed newspapers along with a constant fall in young readers. "Just ...

In a study published today in Pediatrics, scientists at Umeå University in Sweden conclude that giving iron supplements to low birth weight infants reduces the risk of behavior problems like ADHD later in life. The study, Effects of Iron Supplementation on LBW Infants on Cognition and Behavior at 3 Years, is published in the January 2013 issue, released online Dec. 10, 2012. In the randomized controlled trial, researchers in Sweden gave 285 marginally low birth weight infants either 0, 1 or 2 mg/kg and day of iron supplements from 6 weeks to 6 months of age. At age ...

Seniors in long-term care experienced a significant reduction in emergency room visits and depression when receiving palliative care services, according to a recent collaborative study by researchers at Hebrew SeniorLife's Hebrew Rehabilitation Center (HRC) and Institute for Aging Research, both affiliated with Harvard Medical School (HMS). The results of the study, published today in The Gerontologist, demonstrate the potential for improved end-of-life quality of care when palliative services are implemented in a long-term care setting.

A new method that could give a deeper insight into evolutional biology by tracing directionality in gene migration has just appeared in EPJ Data Science. Paolo Masucci from the Centre for Advanced Spatial Analysis, at University College of London, UK, and colleagues identified the segregation of genes that a marine plant underwent during its evolution. They found that the exchange of genes, or gene flow, between populations of a marine plant went westward from the Mediterranean to the Atlantic. This methodology could also be used to estimate the information flow in complex ...

DURHAM, N.C. -- A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury. The findings, published online Dec. 10, 2012, in the journal Small, were demonstrated in individual nerve cells as well as in the brains of mice and rats, and may have future applications in intracranial or spinal devices to help treat neural injuries. Carbon nanotubes are a nanomaterial with unique features, including mechanical strength and electrical conductivity. These characteristics, ...

CAMBRIDGE, Mass. -- Silicon's crown is under threat: The semiconductor's days as the king of microchips for computers and smart devices could be numbered, thanks to the development of the smallest transistor ever to be built from a rival material, indium gallium arsenide. The compound transistor, built by a team in MIT's Microsystems Technology Laboratories, performs well despite being just 22 nanometers (billionths of a meter) in length. This makes it a promising candidate to eventually replace silicon in computing devices, says co-developer Jesús del Alamo, the Donner ...
