New open-source platform accelerates research into the treatment of heart arrhythmia's

2021-02-26
(Press-News.org) An open-source platform, OpenEP co-developed by researchers from the School of Biomedical Engineering & Imaging Sciences at King's College London has been made available to advance research on atrial fibrillation, a condition characterised by an irregular and often fast heartbeat. It can cause significant symptoms such as breathlessness, palpitations and fatigue, as well as being a major contributor to stroke and heart failure.

Current research into the condition involves the interpretation of large amounts of clinical patient data using software written by individual research groups.

But a new study recently published in Frontiers in Physiology shows that the OpenEP platform, developed in collaboration between King's College London, the University of Edinburgh, Invicro, a Konica Minolta Company, Guy's and St Thomas' NHS Foundation Trust and Imperial College London, is capable of doing close to 90 per cent of the types of analyses that are performed in contemporary electrophysiology studies, enabling researchers to focus on their specific hypothesis or research question.

Having a standardised way of using data processing techniques can also help to make them reproducible for other scientists.

Lead author, Dr Steven Williams, Honorary Senior Lecturer at King's School of Biomedical Engineering & Imaging Sciences said the platform lowers barriers of entry to electrophysiology research.

"For clinicians who may wish to do this sort of research but have not been able to before because of the significant barriers, many of these are now overcome. It is now possible to get the clinical data into a standardised format using the OpenEP and analyse it without writing specialised programmes," Dr Williams said.

Dr Williams said as the code is open source, the research community can verify that the methods are implemented correctly and update them, if required.

The software contained in the platform has been under development for ten years and has been used in a number of electrophysiology research projects at King's College London.

In addition to its impact on atrial fibrillation research, OpenEP is already being used for research into other arrhythmias by collaborating institutions.

Dr Nick Linton, Consultant Cardiologist & Senior Lecturer at Imperial College London and a senior author of the study said: "We hope that OpenEP will foster collaboration with new and existing researchers in this exciting area of cardiology. Arrhythmias are a leading cause of morbidity in the UK, and we are confident that OpenEP will help to accelerate progress towards innovative treatments."

Advantageous preparation of movement via independent control of muscle sensors

Advantageous preparation of movement via independent control of muscle sensors
2021-02-26
A number of brain areas change their activity before we execute a planned voluntary movement. A new study by Umeå University identifies a novel function of this preparatory neural activity, highlighting another mechanism the nervous system can use to achieve its goals. Voluntary movements are prepared before they are executed. For example, such 'preparation' occurs in the period between seeing a coffee cup and starting to reach for it. Neurons in many areas of the brain change their activity during movement preparation in ways that reflect different aspects of ...

"Stark warning": Combating ecosystem collapse from the tropics to the Antarctic

2021-02-26
Eminent scientists warn that key ecosystems around Australia and Antarctica are collapsing, and propose a three-step framework to combat irreversible global damage. Their report, authored by 38 Australian, UK and US scientists from universities and government agencies, is published today in the international journal Global Change Biology. Researchers say I heralds a stark warning for ecosystem collapse worldwide, if action if not taken urgently. Lead author, Dr Dana Bergstrom from the Australian Antarctic Division, said that the project emerged from a conference inspired by her ecological research in polar environments. "I was seeing unbelievably rapid, widespread dieback in the alpine tundra of World Heritage-listed Macquarie Island and started wondering if this ...

Novel catalysts improve efficiency of urea synthesis at ambient conditions

Novel catalysts improve efficiency of urea synthesis at ambient conditions
2021-02-26
Converting both nitrogen (N2) and carbon dioxide (CO2) into value-added urea molecules via C-N coupling reaction is a promising method to solve the problem of excessive CO2 emissions. Compared with huge energy consumption industrial processes, the electrochemical urea synthesis provides an appealing route under mild conditions. However, it still faces challenges of low catalytic activity and selectivity. A research team led by Prof. ZHANG Guangjin from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences fabricated Bi-BiVO4 Mott-Schottky heterostructure catalysts for efficient urea synthesis at ambient conditions. This work was published in Angewandte Chemie International ...

Nanoparticles help untangle Alzheimer's disease amyloid beta plaques

Nanoparticles help untangle Alzheimers disease amyloid beta plaques
2021-02-26
ROCKVILLE, MD - Scientists are still a long way from being able to treat Alzheimer's Disease, in part because the protein aggregates that can become brain plaques, a hallmark of the disease, are hard to study. The plaques are caused by the amyloid beta protein, which gets misshapen and tangled in the brain. To study these protein aggregates in tissue samples, researchers often have to use techniques that can further disrupt them, making it difficult to figure out what's going on. But new research by Vrinda Sant, a graduate student, and Madhura Som, a recent PhD graduate, in the lab of Ratnesh Lal at the University of California, San Diego, provides a new technique for studying amyloid beta and could be useful in future Alzheimer's treatments. Sant and her colleagues will present their research ...

Social media use driven by search for reward, akin to animals seeking food

2021-02-26
Our use of social media, specifically our efforts to maximize "likes," follows a pattern of "reward learning," concludes a new study by an international team of scientists. Its findings, which appear in the journal Nature Communications, reveal parallels with the behavior of animals, such as rats, in seeking food rewards. "These results establish that social media engagement follows basic, cross-species principles of reward learning," explains David Amodio, a professor at New York University and the University of Amsterdam and one of the paper's authors. "These findings may help us understand why social media comes to dominate daily life for many people and provide clues, borrowed from research on reward learning and addiction, to how troubling online engagement may ...
