Diabetic foot ulcers can take up to 150 days to heal. A biomedical engineering team wants to reduce it to 21 days. They’re planning to drop the healing time by amplifying what the body already does naturally: build layers of new tissue pumped up by nitric oxide. In patients with diabetes, impaired nitric oxide production
A recent study from North Carolina State University and the University of South Carolina finds that young people with good family relationships are more likely to intervene when they witness bullying or other aggressive behavior at school – and to step in if they see victims planning to retaliate. The study found that kids who
The debate about the volume of homework that children are being given has been bouncing around the opinion pages of broadsheets and red tops in recent weeks after Gary Lineker tweeted that it was “a waste of time”. As names are called and sides are taken in the debate there are much bigger issues at
More personalized risk assessments and new cholesterol-lowering drug options for people at the highest risk for cardiovascular disease (CVD) are among the key recommendations in the 2018 cholesterol guidelines from the American Heart Association (AHA) and the American College of Cardiology (ACC). The guidelines were presented today at the Association’s 2018 Scientific Sessions conference in
Most of us have had moments when we’re feeling down—maybe we can’t stop thinking about our worst mistakes, or our most embarrassing memories—but for some, these poor mood states can be relentless and even debilitating. Now, new research from UC San Francisco has identified a common pattern of brain activity that may be behind those
Visceral leishmaniasis (VL) is a life-threatening disease transmitted by the bite of a sand fly. Between 3,700 to 7,400 people in Ethiopia are infected annually, particularly in the northern, agricultural regions with favorable climate and environment to sand fly vectors. A study published in PLOS Neglected Tropical Diseases by Rebecca Coulborn from Epicentre, France, and
Smoking, diabetes and high blood pressure increase the risk of a heart attack more in women than in men, new research from The George Institute for Global Health at the University of Oxford has found. The study, of 472,000 participants aged 40-69, found that smoking, diabetes, high blood pressure and having a BMI >25 puts
Scientists have brought new arguments in support of the hypothesis that individuals with depression tend to be more active in neural systems accountable for ideas about their and themselves group of friends. The findings from the study are printed around the pages from the Journal of Affective Disorders. Based on gazeta.ru, scientists stated that the
People with autoimmune diseases such as psoriasis, lupus and rheumatoid arthritis are at high risk of developing cardiovascular disease, even though none of these conditions seem to target the cardiovascular system directly. Now, researchers at Washington University School of Medicine in St. Louis believe they have begun to understand the link between the two. Researchers
As the adage goes “neurons that fire together, wire together,” but a new paper published today in Neuron demonstrates that, in addition to response similarity, projection target also constrains local connectivity. Researchers from the Sainsbury Wellcome Centre have been looking to elucidate the rules of connectivity of neurons in the neocortex with the long term
Thanks to a quirk in the way our brain evaluates goals, people feel it’s easier to achieve a small incremental goal than to maintain the status quo, when both goals are assessed in isolation. This is especially true if the context is seen as unfavourable. This finding, which contrasts with the popular belief that no
Patients hospitalized with a cardiovascular event are more likely to die within one year if they have low health literacy, according to a Vanderbilt University Medical Center study released today in Mayo Clinic Proceedings. Health literacy is the ability to access and use reliable health information to make decisions, according to the study’s lead author
Melbourne scientists have discovered how tumour development is driven by mutations in the most important gene in preventing cancer, p53. The research revealed that in the early stages of cancer, mutant p53 ‘tackles’ the normal p53 protein and blocks it from carrying out its protective role. As a result, p53 can no longer activate natural
The majority of patients with cystic fibrosis may not achieve blood concentrations of antibiotics sufficiently high enough to effectively fight bacteria responsible for pulmonary exacerbations, leading to worsening pulmonary function, indicates a study led by researchers at Children’s National Health System. Additionally, the study findings show that it’s impossible to predict solely from dosing regimens
Researchers have developed a new nuclear medicine tracer that could improve diagnosis and treatment of non-small cell lung cancer. Research published in the November issue of The Journal of Nuclear Medicine found that the new tracer, 99mTc-HYNIC-cMBP, produced clearer images in less time than currently used tracers and was more rapidly eliminated from the body,
The 21st century has ushered in a “quiet revolution” in the diversity of intimate relationships, and a leading scholar says the scale and pace of this social transformation warrants a “reboot” of relationship studies. Social media and the internet have empowered individuals with diverse identities and relationship practices to find each other, raising awareness of
On the eve of the Melbourne Cup, new research from The Australian National University (ANU) has found more Australians are experiencing gambling harm and suffering life and health hardships for much longer than previously known. In providing one of the first national snapshots of gambling harm in Australia, the Centre for Gambling Research (CGR) has
How does our nervous system motivate us to get off the sofa and walk to the fridge, or even to the supermarket, to get food? A research team led by Alexander Gottschalk from Goethe University investigated this using the threadworm Caenorhabditis elegans. The results indicate how foraging behaviour in higher animals might have evolved. Finding
Scientists have discovered a drug combination that could halt the progression of fibrosis—a condition believed to be responsible for almost half of all deaths—according to a study published in the journal European Urology. Researchers from Anglia Ruskin University, University College London and KU Leuven have spent seven years working on finding the right drug combination
Hospital admissions for atrial fibrillation (AFib), the most common type of irregular heartbeat, rise in the days following the spring transition of daylight saving time, according to preliminary research to be presented in Chicago at the American Heart Association’s Scientific Sessions 2018. At least 2.7 million and possibly as many as 6.1 million American adults
