Blood glucose measure appears to provide little benefit in predicting risk of CVD

2014-03-25
(Press-News.org) In a study that included nearly 300,000 adults without a known history of diabetes or cardiovascular disease (CVD), adding information about glycated hemoglobin (HbA1c), a measure of longer-term blood sugar control, to conventional CVD risk factors like smoking and cholesterol was associated with little improvement in the prediction of CVD risk, according to a study in the March 26 issue of JAMA.

Because higher glucose levels have been associated with higher CVD incidence, it has been proposed that information on blood sugar control might improve doctors' ability to predict who will develop CVD, according to background information in the article.

Emanuele Di Angelantonio, M.D., of the University of Cambridge, United Kingdom, and colleagues with the Emerging Risk Factors Collaboration, conducted an analysis of data available from 73 studies involving 294,998 participants to determine whether adding information on HbA1c levels to information about conventional cardiovascular risk factors is associated with improvements in the prediction of CVD risk. Predicted 10-year risk categories were classified as low ( END

Study finds substantial decrease in use of cardiac imaging procedure

2014-03-25
There has been a sharp decline since 2006 in the use of nuclear myocardial perfusion imaging (MPI; an imaging procedure used to determine areas of the heart with decreased blood flow), a decrease that cannot be explained by an increase in other imaging methods, according to a study in the March 26 issue of JAMA. Nuclear myocardial perfusion imaging accounted for much of the rapid growth in cardiac imaging that occurred from the 1990s through the middle 2000s. Edward J. McNulty, M.D., of Kaiser Permanente Medical Center, San Francisco, and colleagues conducted a study ...

Texas researcher: Peaches inhibit breast cancer metastasis in mice

Texas researcher: Peaches inhibit breast cancer metastasis in mice
2014-03-25
COLLEGE STATION – Lab tests at Texas A&M AgriLife Research have shown that treatments with peach extract inhibit breast cancer metastasis in mice. AgriLife Research scientists say that the mixture of phenolic compounds present in the peach extract are responsible for the inhibition of metastasis, according to the study, which was this month published in the Journal of Nutritional Biochemistry. "Cancer cells were implanted under the skin of mice with an aggressive type of breast cancer cells, the MDA-MB-435, and what we saw was an inhibition of a marker gene in the lungs ...

VIDEO: In early tests, the research team used a Kuka KR5 sixx R650 robot, seen in action here. Click here for more information. When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. A catalyst would have been needed, but enzymes had not yet evolved. One theory is that the catalytic minerals on a meteorite's surface could have jump-started life's first chemical reactions. But scientists need a way to directly ...

Epigenetic alterations disrupt intestinal T cell homeostasis A precise balance between mature T cell subsets is important for intestinal homeostasis. Disruption of T cell populations underlies autoimmune colitis, including inflammatory bowel disease (IBD). Specific transcriptional programs are activated to determine the differentiation fate of naïve T cells; however, the role of epigenetic regulation in T cell maturation in the intestine is unclear. In this issue of the Journal of Clinical Investigation, Colby Zaph and colleagues from the University of British Columbia ...

Salamanders shrinking as their mountain havens heat up

Salamanders shrinking as their mountain havens heat up
2014-03-25
Wild salamanders living in some of North America's best salamander habitat are getting smaller as their surroundings get warmer and drier, forcing them to burn more energy in a changing climate. That's the key finding of a new study, published March 25 in the journal Global Change Biology, that examined museum specimens caught in the Appalachian Mountains from 1957 to 2007 and wild salamanders measured at the same sites in 2011-2012. The salamanders studied from 1980 onward were, on average, 8% smaller than their counterparts from earlier decades. The changes were most ...

ISU engineer builds instrument to study effects of genes, environment on plant traits
2014-03-25
AMES, Iowa – Let's say plant scientists want to develop new lines of corn that will better tolerate long stretches of hot, dry weather. How can they precisely assess the performance of those new plants in different environmental conditions? Field tests can provide some answers. Greenhouse tests can provide some more. But how can plant scientists get a true picture of a plant's growth and traits under a wide variety of controlled environmental conditions? That job has been too big and too precise for most laboratories. There are a few labs around the world that can ...

2014-03-25
Remote acoustic monitoring among endangered whales is the subject of a major article by two doctoral students in Syracuse University's College of Arts and Sciences. Leanna Matthews and Jessica McCordic, members of the Parks Lab in the Department of Biology, have co-authored "Remote Acoustic Monitoring of North Atlantic Right Whales Reveals Seasonal and Diel Variations in Acoustic Behavior." The article appears in the current issue of PLOS ONE, an inclusive, peer-reviewed, open-access resource from the Public Library of Science in San Francisco, Calif. Susan Parks, assistant ...

In search of a few good apps

2014-03-25
BOSTON–While the Food and Drug Administration (FDA) has released guidelines for the regulation of mobile health (mHealth) apps that act as medical devices or as accessories to medical devices, the vast majority of mHealth apps remain unregulated and unevaluated. In a Viewpoint article, "In Search of a Few Good Apps", published in JAMA on March 24, 214, co-authors, David Bates, MD and Adam Landman, MD of Brigham and Women's Hospital (BWH) and Adam Powell, PhD, president of Payer+Provider Syndicate, call for the creation of mHealth (mobile health) app review and certification ...

Wild salamanders living in some of North America's best salamander habitat are getting smaller as their surroundings get warmer and drier, forcing them to burn more energy in a changing climate. That's the key finding of a new study co-authored by a Clemson University biologist and published Tuesday in the journal Global Change Biology that examined museum specimens caught in the Appalachian Mountains from 1957 to 2007 and wild salamanders measured at the same sites in 2011-2012. The salamanders studied from 1980 onward were, on average, eight percent smaller than their ...

WEST LAFAYETTE, Ind. — Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules. A team of researchers from Purdue University and the Indian Institute of Technology Madras performed the study, which ...
