DARIEN, IL - A new study suggests that increased restless legs syndrome (RLS) severity is associated with subsequent increased risk of stroke. Results show that increased RLS severity is associated with subsequent increased risk of stroke, after considering other known risk factors such as age, smoking, hypertension, and unhealthy diet. There were 161 incident stroke cases during the six-year follow-up. "We were surprised at the importance of taking into account RLS severity -- it was only severe RLS, not milder RLS, that was associated with increased risk of stroke," ...

DARIEN, IL - A new study suggests that lower life satisfaction is linked to sleep problems during midlife. Respondents with higher life satisfaction reported shorter sleep onset latency (SOL). Sleep onset delay among those with low life satisfaction could be the result of worry and anxiety, as reported elsewhere. These findings support the idea that life satisfaction is interlinked with many measures of sleep and sleep quality, suggesting that improving one of these variables might result in improving the other. "These findings support the idea that life satisfaction ...

URBANA, Ill. - Emerging adults aged 18 to 25 are often criticized for their poor interpersonal skills, sense of entitlement, and casual work ethic. But a new University of Illinois study suggests that fault-finding adult co-workers could make a big difference in young workers' leadership development by developing relationships with them, modeling the behaviors they wish to see, and providing leadership growth opportunities. "Young adults in our study had learned a lot from mentors who modeled initiative, drive, and persistence; demonstrated how to communicate with confidence ...

DARIEN, IL - A new study suggests that children with traumatic brain injuries (TBI) have poorer sleep and more daytime sleepiness in comparison to healthy children. Results show that children with TBI were more likely to experience greater daytime sleepiness, sleep disturbances and a poorer overall sleep quality. The children with TBI also had impaired emotional, physical and social functioning when compared to healthy children. "We were surprised that children with a TBI experienced persistent increases in daytime sleepiness and decreases in sleep quality compared ...

This news release is available in German. Material scientists at ETH Zurich and the Max Planck Institute of Colloids and Interfaces in Potsdam have developed a new type of sensor that can measure carbon dioxide (CO2). Compared with existing sensors, it is much smaller, has a simpler construction, requires considerably less energy and has an entirely different functional principle. The new sensor consists of a recently developed composite material that interacts with CO2 molecules and changes its conductivity depending on the concentration of CO2 in the environment. ...

Jackson Laboratory researchers have shown that using an electric current to deliver the CRISPR/Cas9 system, in order to engineer genetic changes in laboratory mice, is highly efficient and significantly improves the system's throughput. CRISPR/Cas9 has significantly enhanced the precision, speed and ease with which experimental organisms can be genetically modified in order to create models of human diseases. Mice carrying mutations in single or multiple genes or other modifications can be created in one step by injecting the CRISPR/Cas9 system into zygotes (the cells ...

Metabolism experts are increasingly convinced that obesity and many of the pathogenic changes it entails, such as Metabolic Syndrome and type 2 diabetes, are a result of chronic inflammatory processes in fatty (adipose) tissue. The adipose tissue of obese people exhibits higher-than-normal quantities of almost all types of immune and inflammatory cells. "We are quite convinced that immune cells play a role in the pathogenic consequences of obesity," says Professor Hans-Reimer Rodewald of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ). "But ...

Scientists have discovered a trigger that allows breast cancer cells to spread to the lungs. They have found that blocking the signals in mice with breast cancer greatly reduces the number of secondary tumours found in the lungs. The findings could lead to new therapies that stop the progression of breast cancer, the researchers at the University of Edinburgh say. The majority of deaths from breast cancer are caused by the tumour spreading to other parts of the body. The lung is often one of the first organs to be affected. Researchers at the University's MRC Centre ...

Recently, a group of Chinese researchers proposed an approach to verify the correctness of train control system by combining simulation and formal verification, which was published ...

New research from Uppsala University shows promising progress in the use of stem cells for treatment of spinal cord injury. The results, which are published in the scientific journal Scientific Reports, show that human stem cells that are transplanted to the injured spinal cord contribute to restoration of some sensory functions. Traffic accidents and severe falls can cause ruptures of nerve fibers that enter/exit the spinal cord. Most commonly, these avulsion injuries affect the innervation of the arm and hand, and lead to paralysis, loss of sensation and cause chronic ...

Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic/), a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups. The presence of this wave is one of the consequences scientists were expecting to observe in the quark-gluon plasma--a state of matter that existed in the early ...

Researchers at the KU Leuven Centre for Surface Chemistry and Catalysis have found a more eco-friendly way to derive lignin - a paper industry waste product - from wood and convert it into chemical building blocks. The resulting chemicals can be used in paint, insulation foam, and several other products. The researchers published their findings in the journal Energy & Environmental Science. Lignin is a substance in the cell walls of plants that strengthens their structure. When wood is processed into paper pulp, lignin is produced as a waste product. Researchers have ...

CINCINNATI - Children who received general anesthesia for surgery before age 4 had diminished language comprehension, lower IQ and decreased gray matter density in posterior regions of their brain, according to a new study in the journal Pediatrics. Researchers from Cincinnati Children's Hospital Medical Center report their findings in the journal's June 8 online edition. The authors recommend additional studies to determine anesthesia's precise molecular effects on the brain and contribution to diminished brain function and composition. Researchers say this knowledge ...

Philadelphia, PA, June 8, 2015 - Barrett's esophagus (BE) develops in a subset of patients with gastroesophageal reflux disease (GERD) and can increase the risk of developing cancer of the esophagus. Although periodic surveillance for cancer is recommended for BE patients, these examinations may fail to identify pre-cancerous dysplasia and early cancers. A report in the Journal of Molecular Diagnostics describes a test using next-generation sequencing (NGS) to detect genomic mutations in precancerous esophageal tissue, which may improve cancer surveillance and early detection ...

Just one in 20 people worldwide (4·3%) had no health problems in 2013, with a third of the world's population (2·3 billion individuals) experiencing more than five ailments, according to a major new analysis from the Global Burden of Disease Study (GBD) 2013, published in The Lancet. Moreover, the research shows that, worldwide, the proportion of lost years of healthy life (disability-adjusted life years; DALYS [1]) due to illness (rather than death) rose from around a fifth (21%) in 1990 to almost a third (31%) in 2013. As the world's population grows, ...

Sarcopenia is the aging-related loss of skeletal muscle mass and strength. Preventing sarcopenia is important for maintaining a high quality of life (QOL) in the aged population. However, the molecular mechanism of sarcopenia has not yet been unraveled and is still a matter of debate. Determining whether the levels of autophagy-related mediators (e.g., p62/SQSTM1, LC3, etc.) in muscle change with ageing is important to understanding sarcopenia. Such information could enhance the therapeutic strategies for attenuating mammalian sarcopenia. In previous studies, autophagic ...

Debates about legalizing marijuana have focused on crime rates, economic benefits, and health effects among adults. But a study published today from researchers at Nationwide Children's Hospital shows that the risk to young children of swallowing, breathing in or otherwise being exposed to marijuana also needs to be considered. The study, published online today in Clinical Pediatrics, found that the rate of marijuana exposure among children 5 years of age and younger rose 147.5 percent from 2006 through 2013 across the United States. The rate increased almost 610 percent ...

SEATTLE -- People across the world are living longer but spending more time in ill health as rates of nonfatal diseases and injuries - including diabetes and hearing loss - decline more slowly than death rates, according to a new analysis of 301 diseases and injuries in 188 countries. Using a measurement known as years lived with disability, or YLDs, researchers from around the world quantified the impact of health problems that impair mobility, hearing, or vision, or cause pain in some way but aren't fatal. In 2013, low back pain and major depressive disorder were among ...
