Chicago (July 7, 2015)- Switzerland has a long history of trying to be as self-sufficient and energy independent as possible. Although its energy supply system has served it well in the past, the country is now looking to turn away from its reliance on nuclear power and seeks to compensate for the energy lost from hydropower as a result of climate change. In the latest issue of the Bulletin of the Atomic Scientists, published by SAGE, Dominic Notter of Empa discusses how the country aims to address this transition, finding a new supply mix that combines energy conservation, ...

Scientists at the University of California, Davis, have identified a key mechanism in neuropathic pain. The discovery could eventually benefit millions of patients with chronic pain from trauma, diabetes, shingles, multiple sclerosis or other conditions that cause nerve damage. A biological process called endoplasmic reticulum stress, or ER stress, is the significant driver of neuropathic pain, said lead researchers Bora Inceoglu of the UC Davis Department of Entomology and Nematology and UC Davis Comprehensive Cancer Center, and Ahmed Bettaieb, Department of Nutrition. ...

LOS ANGELES (July 6, 2015) - Cedars-Sinai researchers have successfully tested two new methods for preserving cognition in laboratory mice that exhibit features of Alzheimer's disease by using white blood cells from bone marrow and a drug for multiple sclerosis to control immune response in the brain. Under the two approaches, immune cells from outside the brain were found to travel in greater numbers through the blood into the brain. The study showed measurable benefits in mice, an encouraging step toward further testing of these potentially powerful strategies in human ...

New research suggests guidelines on children's exposure to radio frequency waves from technology are confusing for parents. The review into the polices of 34 countries, carried out by Dr Mary Redmayne, from the Department of Epidemiology and Preventive Medicine at Monash University, found varying degrees of advice about children's exposure to radio frequency electromagnetic fields (RF-EMF). RF-EMFs are emitted from technology including WiFi, tablets and mobile phones. Associated with an increased risk of some brain tumours in heavy and long-term phone users, RF-EMFs ...

ARLINGTON HEIGHTS, Ill. (July 7, 2015) - Parents of kids with severe allergies know how scary a severe allergic reaction (anaphylaxis) is. New research offers clues as to why some kids can have a second, related reaction hours later - and what to do about it. A study in the Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI), examined records of 484 children seen in an emergency department (ED) for anaphylaxis. The researchers tracked whether there was a second, follow-up reaction. Delayed ...

When Greek mythology and cell biology meet, you get the protein Callipygian, recently discovered and named by researchers at The Johns Hopkins University for its role in determining which area of a cell becomes the back as it begins to move. The findings, made in the amoeba Dictyostelium discoideum, shed light on how symmetrical, round cells become "polarized," or asymmetrical and directional. A summary of the findings was published online June 30 in the Proceedings of the National Academy of Sciences. "Cells have to have a front and a back to migrate," says Peter ...

Scientists have discovered new ways in which the malaria parasite survives in the blood stream of its victims, a discovery that could pave the way to new treatments for the disease. The researchers at the Medical Research Council's (MRC) Toxicology Unit based at the University of Leicester and the London School of Hygiene & Tropical Medicine identified a key protein, called a protein kinase, that if targeted stops the disease. The study is published today (Tuesday) in Nature Communications. Malaria is caused by a parasite that lives inside an infected mosquito and ...

Testing thousands of approved drugs, EPFL scientists have identified an unlikely anti-tuberculosis drug: the over-the-counter antacid lansoprazole (Prevacid®). Tuberculosis continues to be a global pandemic, second only to AIDS as the greatest single-agent killer in the world. In 2013 alone, the TB bug Mycobacterium tuberculosis caused 1.5 million deaths and almost nine million new infections. Resistance to TB drugs is widespread, creating an urgent need for new medicines. EPFL scientists have now identified lansoprazole, a widely used, over-the-counter antacid, as ...

New research from the University of Copenhagen and Herlev and Gentofte Hospital shows that high vitamin C concentrations in the blood from the intake of fruit and vegetables are associated with a reduced risk of cardiovascular disease and early death. Fruit and vegetables are healthy. We all know that. And now there is yet another good reason for eating lots of it. New research from the University of Copenhagen shows that the risk of cardiovascular disease and early death falls with a high intake of fruit and vegetables, and that this may be dued to vitamin C. The ...

CHARLOTTESVILLE, VA (JULY 7, 2015). Researchers at Brown University examined three magnetically programmable shunt valves to see if the magnetic field emissions of headphones can cause unintentional changes in shunt valve settings. Based on their findings, the researchers state that it is highly unlikely that commercially available headphones will interfere with programmable shunt valve settings. Full details of this study can be found in "Programmable shunts and headphones: Are they safe together?" by Heather S. Spader, MD, and colleagues, published today online, ahead ...

CHARLOTTESVILLE, VA (JULY 7, 2015). Researchers conducted a prospective observational study in elderly patients and adult patients receiving antiplatelet therapy who presented with mild head injury at two trauma hospitals in Vienna: the Trauma Hospital Meidling and the Donauspital. The focus of the study was to see if blood serum levels of S100B protein in these patients could help identify whether their injuries included intracranial bleeding. If there was no indication of intracranial hemorrhage, these patients would not need additional testing or hospitalization. The ...

Policymakers and developers planning high-density housing near public transit with the goal of reducing automobile use and greenhouse gas emissions that contribute to global warming need a clearer understanding of the health risks from air pollution that may be created if that housing is also built near busy roads and freeways, according to new research by Keck School of Medicine of the University of Southern California (USC) scientists. The study is one of the first to focus on the burden of heart disease that can result from residential exposures near major roadways ...

Weather is frequently portrayed in popular music, with a new scientific study finding over 750 popular music songs referring to weather, the most common being sun and rain, and blizzards being the least common. The study also found many song writers were inspired by weather events. The study, led by the University of Southampton, together with the Universities of Oxford, Manchester, Newcastle (all part of the Tyndall Centre for Climate Change Research) and the University of Reading analysed the weather through lyrics, musical genre, keys and links to specific weather ...

Faith-based organisations [1] are crucial in achieving the promise of universal health coverage--an adequate standard of health care for all people--especially for poor and marginalised groups, according to a new three-part Series on faith-based health care, published in The Lancet. The Series argues that building on the extensive experience, strengths, and capacities of faith-based organisations (eg, geographical coverage, influence, and infrastructure) offers a unique opportunity to improve health outcomes. Because of their broad reach and influence, faith-based groups ...

Drinking alcohol while pregnant is common, ranging from 20% to 80% among those questioned in the UK, Ireland, Australia and New Zealand, reveals a study of almost 18,000 women published in the online journal BMJ Open. Women across all social strata drank during pregnancy, the findings showed. But expectant mums were significantly more likely to be drinkers if they were also smokers. The researchers base their findings on an analysis of data from three studies: The Growing up in Ireland (GUI) study; the Screening for Pregnancy Endpoints (SCOPE) study; and the Pregnancy ...

The heightened risk of death after admission to hospital at the weekend--the so-called 'weekend effect'--is a feature of several developed countries' healthcare systems, and not just a problem for hospitals in England, reveals research published online in BMJ Quality & Safety. The international nature of the findings suggests that this is a systematic phenomenon that not only crosses time, but also space, say the researchers. In a bid to look in more detail at the evidence for the link between higher rates of death for patients admitted to hospital at weekends compared ...

A new smartphone app warns drinkers if they go over the recommended maximum daily/weekly units of alcohol, to help them better manage their intake, reveals a commentary published in the online journal BMJ Innovations. The Alcohol Tracker, which has been developed by doctors and based on the clinical evidence of what works best, also provides built-in psychological therapies and helpline links for users to help steer them away from hazardous drinking. Excess alcohol kills millions worldwide every year, but many available smartphone apps to manage drinking are not informed ...

1. For patients with no history of stroke, even very small brain lesions increase risk for death Free abstract: http://www.annals.org/article.aspx?doi=10.7326/M14-2057 URL goes live when embargo lifts For asymptomatic patients with no history of clinical stroke, having even very small brain lesions (less than 3 mm) detected by magnetic resonance imaging (MRI) triples their risk for stroke and death, according to a study published in Annals of Internal Medicine. Having both very small and larger lesions increases the risk to eight-fold. Subclinical brain infarctions ...

Scientists with the University of Mississippi Medical Center (UMMC) and colleagues found that very small brain lesions noted on brain imaging that would typically be disregarded by clinicians are associated with a heightened risk of stroke and death. The findings are in today's (July 7, 2015) Annals of Internal Medicine. The discovery about these tiny lesions -- areas of the brain where tissue may have been damaged by injury or disease -- may help physicians identify people at risk of stroke and death as early as middle age, even when they are displaying no symptoms of ...

A study in the online edition of Annals of Internal Medicine suggests that coronary artery calcification (CAC) scans could help physicians identify patients at risk for premature death. According to the National Institutes of Health, a CAC is an x-ray test that looks for specks of calcium in the walls of the coronary arteries. These specks of calcium are called calcifications and are an early sign of coronary artery disease. Researchers from Emory University School of Medicine, led by Leslee Shaw, PhD, professor of cardiology, collected and assessed CAC scores and ...

In a first-of-its-kind study, researchers have investigated the impact of different walking aids on patients with chronic obstructive disease (COPD). Walking with the help of a rollator (a frame with wheels, handlebars, and a built-in seat) resulted in the longest distance walked and most time spent walking. The use of walking with assistance of a draisine (a bicycle without pedals) improved walking speed with fewer strides but did not improve the time spent walking by COPD patients to cover a longer distance. "Patients with COPD walked significantly further and longer ...

In a study of 1159 males who illicitly used amphetamines, half of participants said drug use had no impact on their sexual functions, while the other half reported impacts such as reduced erectile rigidity and sexual satisfaction, enhanced orgasmic intensity, and delayed ejaculation. "Compared with 211 matched controls, amphetamine users were twice as likely to experience erectile dysfunction," said Dr. Bang-Ping Jiann, senior author of The Journal of Sexual Medicine study. Amphetamines are a group of drugs that stimulate the central nervous system and contain ingredients ...

Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, Johns Hopkins scientists appear to have cast a shadow of doubt on that theory. A report on their study is published online this week in Proceedings of the National Academy of Sciences. "We confirmed that this calcium channel is important for heart function," says senior investigator Mark Anderson, ...

July 6, 2015 CHAPEL HILL, NC - Insulin resistance affects tens of millions of Americans and is a big risk factor for heart disease. Yet, some people with the condition never develop heart disease, while some experience moderate coronary blockages. Others, though, get severe atherosclerosis - multiple blockages and deterioration of coronary arteries characterized by thick, hard, plaque-ridden arterial walls. Researchers at the UNC School of Medicine created a first-of-its-kind animal model to pinpoint two biomarkers that are elevated in the most severe form of coronary disease. The ...

Researchers have found several key differences among people who receive hospice care--which maintains or improves the quality of life for someone whose condition is unlikely to be cured--in assisted-living facilities (ALFs) compared with people who receive hospice care at home. People receiving hospice care in ALFs were more likely to be older and female than people who received hospice care at home. Also, people living in ALFs enrolled in hospice care much earlier than patients living in home settings. This allowed them to receive more help from the hospice team before ...
