PHOENIX -- If you are over age 75, and taking an anticoagulant, the old standard may be the gold standard, Mayo Clinic researchers and collaborators have determined. In a study released online in April in the BMJ, a team of researchers from Mayo Clinic, and other collaborators, showed that for older patients, particularly individuals greater than 75 years of age, the risk of gastrointestinal (GI) bleeding is 3 to 5 times higher when taking newer anticoagulant medications dabigatran or rivaroxaban compared to when using warfarin. One of the most common reasons people ...

At a traditional stone-laying ceremony outside La Serena, Chile on April 14th, construction officially began of the Large Synoptic Survey Telescope (LSST). This ambitious international astrophysics project is slated to start scanning the heavens in 2022. When it does, LSST should open up the "dark universe" of dark matter and dark energy--the unseen substance and force, respectively, composing 95 percent of the universe's mass and energy--as never before. On April 2, 2015, the Director of LSST, Steven Kahn, along with astrophysicist Sarah Bridle and theoretical physicist ...

The study, published May 29 in the open access Nature Publishing Group journal Scientific Reports, reveals a direct link between the main culprit of Alzheimer's disease and memory loss. Alzheimer's disease is characterized by the formation of amyloid plaques in the brain tissue. These amyloid plaques are made up of an insoluble protein, 'Amyloid-beta' (Abeta), which forms small structures called 'oligomers' that are important in the disease progression. Although these proteins are known to be involved in Alzheimer's, little is understood about how they lead to memory ...

One of the main health targets proposed by the UN Sustainable Development Goals (SDG) is to reduce by one-third premature mortality from non-communicable diseases such as cancer, stroke and dementia. The goals for 2016-2030 define premature mortality as deaths occurring among people aged 69 years old or younger. The proposed SDG target sends an unambiguous statement to UN member states that health provision for younger groups must be prioritised at the expense of people aged 70 or more, according to the international group of signatories of the letter published in The ...

May 29, 2015 - People with dementia and other forms of cognitive impairment (CI) have altered responses to pain, with many conditions associated with increased pain sensitivity, concludes a research review in PAIN®, the official publication of the International Association for the Study of Pain. The journal is published by Wolters Kluwer. The available evidence questions the previous notion that people with CI have reduced pain sensitivity to pain. Rather, "It appears that those with widespread brain atrophy or neural degeneration...all show increased pain responses ...

The 54-question Trauma Symptoms Checklist for Children (TSCC) has been used for decades to test how trauma affects youth in hopes of developing the best treatment and support possible. But interpreting the results can be labor intensive and difficult because the work is done manually and involves a complex matrix from which to draw conclusions. Now, a Case Western Reserve University social work research team, led by Fredrick Butcher, PhD, a research associate at the Semi J. and Ruth W. Begun Center for Violence Prevention Research and Education, has proposed and tested ...

(WASHINGTON, May 29, 2015) - A new report demonstrates that clinical and genetic factors affecting dose requirements for warfarin vary by race. The study, published online today in Blood, the Journal of the American Society of Hematology (ASH), proposes race-specific equations to help clinicians better calculate warfarin dosage. Warfarin is the most widely used blood thinning medication, or anticoagulant, prescribed to prevent stroke and to treat blood clots. Determining the optimal warfarin dose to prevent clots while avoiding dangerous bleeding is difficult. To ensure ...

One recent spring day, John Durban, a NOAA Fisheries marine mammal biologist, stood on the California coast and launched an unmanned aerial vehicle into the air. The hexacopter--so called because it has six helicopter-type rotors--zipped over the ocean and hovered above a gray whale mother and her calf. The pair was migrating north from their calving grounds off Baja California, Mexico, to their summer feeding grounds in the Arctic. NOAA Fisheries scientists have stood at this point of land each year for the past 22 years, binoculars in hand, to estimate the number of ...

Life-threatening liver inflammation can be caused by excess alcohol, fatty foods, toxins, as well as viral, bacterial, and parasite infections. A study published on May 28th in PLOS Pathogens reports that a specific immune cell type in the liver can dampen the immune response, reduce inflammation, and protect against liver damage. Alain Beschin, from the Vrije Universiteit Brussel, Belgium, and colleagues studied the immune response to trypanosome parasites in mice, where they frequently cause liver inflammation and failure. They focused on the role of monocytes, immune ...

The human sensory systems contend with enormous diversity in the natural world. But it has been known for a long time the brain is adapted to exploit statistical regularities that nonetheless arise amongst this diversity. Research publishing this week in PLOS Computational Biology reports that established statistical distributions of visual features, such as visual contrast, spatial scale and depth, differ between dark and bright components of the natural world. For scientists Emily Cooper and Anthony Norcia, gaining a more detailed description of statistical regularities ...

Retrograde amnesia is the inability to recall established memories. In humans, amnesia is associated with traumatic brain injury, Alzheimer's disease, and other neurological conditions. Whether memories lost to amnesia are completely erased or merely unable to be recalled remains an open question. Now, in a finding that casts new light on the nature of memory, published in Science, researchers from the RIKEN-MIT Center for Neural Circuit Genetics demonstrated in mice that traces of old memories do remain in the amnestic brain, and that the cellular pathways underlying them ...

Elevated plasma triglyceride level is considered a risk factor for type-2 diabetes, but new findings suggest that a genetically-elevated triglyceride level is associated with protection against type-2 diabetes. Yann Klimentidis, an Assistant Professor at the Mel and Enid Zuckerman College of Public Health at the University of Arizona, and colleagues found that triglyceride-increasing alleles are associated with decreased type-2 diabetes incidence. Their findings were published recently in PLOS Genetics. Building on previous studies that hinted to the same association, ...
