Oncologists may soon have an accurate and inexpensive way of differentiating between types of ovarian cancer that will improve how patients are treated, thanks to findings from a national research study co-led out of the University of Alberta.
"One of the issues with ovarian cancer is that we cannot fully decipher between subtypes," said Lynne Postovit, U of A oncology researcher and co-director of the Cancer Research Institute of Northern Alberta. "This is an important problem because the different subtypes should be treated differently."
For over 100 years, scientists have sought to understand what links a person's general intelligence, health and aging. In a new study, a University of Missouri scientist suggests a model where mitochondria, or small energy producing parts of cells, could form the basis of this link. This insight could provide valuable information to researchers studying various genetic and environmental influences and alternative therapies for age-related diseases, such as Alzheimer's disease.
MADISON -- Induced pluripotent stem (iPS) cells are among the most important tools in modern biomedical research, leading to new and promising possibilities in precision medicine. To create them requires transforming a cell of one type, such as skin, into something of a blank slate, so it has the potential to become virtually any other kind of cell in the body, useful for regenerative therapies for everything from heart disease to diabetes.
Potentially life-saving cancer risk assessment tools are being widely underused by general practices across the UK, according to new research.
A team of experts from the University of Exeter's Medical School has designed a set of risk assessment tools - which can predict the likelihood of undiagnosed cancer based on patients' symptoms, test results and other clinical information. Now, new NIHR-funded research has reviewed how well used the tools are within health practices.
A new type of money that allows users to make decisions based on information arriving at different locations and times, and that could also protect against attacks from quantum computers, has been proposed by a researcher at the University of Cambridge.
A study of over 87,000 documents obtained through Freedom of Information requests has revealed a contract mechanism that could allow Coca-Cola to "quash" findings from some of the health research it funds at public universities in the US and Canada.
The study, published today in the Journal of Public Health Policy, identified several clauses in legal documents that give the company early sight of any findings, combined with the right to "terminate without reason" and walk away with the data and intellectual property.
Better-qualified staff maintain the quality of state-funded preschools, making up for the larger number of children per staff member in comparison to private and voluntary settings, finds a new study by researchers at the University of Oxford. They also show that the quality of private early years settings can be predicted by staff qualifications, and for voluntary settings, an in-house training plan and a better staff to child ratio.
A new study in Oxford Economic Papers suggests that developed counties may see significant economic gains from their efforts to combat terrorist threats. Developing counties, in contrast, appear to suffer economically from counterterrorism threats.
PRINCETON, N.J.--It's a classic policy dispute: How much should the current generation invest in reducing carbon emissions for the benefit of future generations?
A study published in Nature Communications helps answer this question by quantifying whether reducing carbon emissions -- which will have global benefits in the future -- also improves air quality now. Preventing many of the human health burdens that result from air pollution would be a powerful positive incentive to act sooner than later.
DALLAS, May 7, 2019 - Drinking water that is contaminated with arsenic may lead to thickening of the heart's main pumping chamber in young adults, a structural change that increases the risk for future heart problems, according to new research in Circulation: Cardiovascular Imaging, an American Heart Association journal.
The price tag for cutting global emissions may seem expensive, until the human toll of deaths from air pollution and climate change are factored in, new research says.
The new study in Nature Communications reports that immediate, dramatic cuts in carbon emissions - aggressive enough to meet the Paris Climate Agreement - are economically sound if human health benefits are factored in.
CHAMPAIGN, Ill. -- Researchers report that a protein known to be important to protein synthesis also influences muscle regeneration and regrowth in an unexpected manner. The discovery, reported in the Journal of Clinical Investigation, could one day lead to new methods for treating disorders that result in muscle weakness and loss of muscle mass, the researchers said.
Scientists have long studied leucine tRNA-synthetases, or LRS, for its role in protein synthesis, said University of Illinois cell and developmental biology professor Jie Chen, who led the research.
CHAMPAIGN, Ill. -- A fortuitous conversation between two University of Illinois scientists has opened a new line of communication between biomedical researchers and the tissues they study. The new findings, reported in the Proceedings of the National Academy of Sciences, show that high-intensity focused ultrasound waves can penetrate biological tissue to activate molecules able to perform specific tasks.
PROVIDENCE, R.I. [Brown University] -- Splash some water on a hot skillet, and you'll often see the droplets sizzle and quickly evaporate. But if you really crank up the heat, something different happens. The droplets stay intact, dancing and skittering over the surface in what's known as the Leidenfrost effect. Now a team of researchers has detailed how these Leidenfrost droplets meet their ultimate fate.
Leesburg, VA, May 5, 2019--The upgraded picture archiving and communication system (PACS) improves over the prior system in reduced time spent searching for prior studies and total time spent reading studies, according to a study to be presented at the ARRS 2019 Annual Meeting, set for May 5-10 in Honolulu, HI.
