Uppsala University scientists have designed a new mouse model that facilitates study of factors contributing to the progression of human bladder cancer and of immune-system activation when the tumour is growing. Using this model, they have been able to study how proteins change before, while and after a tumour develops in the bladder wall. The study has now been published in the scientific…
Although the coronavirus affects men and women differently, the vast majority of clinical trials do not mention sex/gender, a new analysis of 4,420 studies concludes. Ultimately, it can influence the treatment negatively. The meta analysis is published in Nature Communications. According to the new research, only 4 percent of 4,420 registered studies explicitly plan to address sex and gender in…
A new way to target a mutant protein which can cause the deadliest of cancers in humans has been uncovered by scientists at Leeds. The mutated form of the RAS protein has been referred to as the “Death Star” because of its ability to resist treatments and is found in 96% of pancreatic cancers and 54% of colorectal cancers. RAS is a protein important for health but in its mutated form it can…
Researchers have identified a way to improve the immune response in the face of severe viral infections. It is widely known that severe viral infections and cancer cause impairments to the immune system, including to T cells, a process called immune ‘exhaustion’. Overcoming immune exhaustion is a major goal for the development of new therapies for cancer or severe viral infections.
The tell-tale signs of a person’s susceptibility to a stroke may appear up to 10 years before the event, suggests research published online in the Journal of Neurology Neurosurgery & Psychiatry. Stroke patients experienced much steeper declines in cognitive abilities and routine daily functioning, starting around a decade before their first stroke, than people who didn’t have a stroke,…
A new report that could help improve how immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) are used in healthcare education and training has been published with significant input from the University of Huddersfield. Professor David Peebles, Director of the University’s Centre for Cognition and Neuroscience, and Huddersfield PhD graduate Matthew Pears contributed to…
A study by Newcastle University, University of East Anglia and charity Fifth Sense, shows poor levels of understanding and care from GPs and specialists about smell and taste loss in patients. This is an issue that has particularly come to the forefront during the Covid-19 pandemic as many people who have contracted the virus report a loss of taste and smell as their main symptoms.
Excessive noise, hearing loss, vascular constriction, old age – hearing difficulties can be caused by many factors. To help improve the quality of life of people with hearing impairment, Mannheim start-up Vibrosonic have developed a new hearing aid with an integrated loudspeaker that sits directly on the eardrum. This hearing contact lens is not an implant, and the sound quality it delivers…
Computer models have been standard tools in basic biomedical research for many years. However, around 70 years after the first publication of an ion current model of a nerve cell by Hodgkin & Huxley in 1952, researchers at Graz University of Technology (TU Graz), in collaboration with the Medical University of Graz and the Memorial Sloan Kettering Cancer Center in New York, have finally…
A pandemic is not a game. Yet, human response in dealing with Covid-19 resembles patterns known from games: people hoard resources, compare leaderboards and graphs, play certain social roles, establish a good-versus-evil narrative, and align themselves with prominent hero figures. The reasoning behind this is simple.
Aerosol generated by playing woodwind and brass instruments is less than that produced when vocalising (speaking and singing) and is no different than a person breathing, new research has found. The findings could be crucial to developing a roadmap for lifting Covid-19 restrictions in the performing arts, which have been significantly restricted since the start of the pandemic.
Researchers at RMIT University in Australia have developed smart wound dressings with built-in nanosensors that glow to alert patients when a wound is not healing properly. The multifunctional, antimicrobial dressings feature fluorescent sensors that glow brightly under UV light if infection starts to set in and can be used to monitor healing progress.
Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it’s no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components…
When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluoresence images from live cells, researchers at the University of Zurich have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.
234 random passersby got the opportunity to try a new virtual reality game, when researchers from the University of Copenhagen visited Fælledparken to test the efficiency of VR technology within health information. During the event, the participants tried their strength against a new VR game that simulates the effect of herd immunity. The game is developed by researchers at the Virtual Learning…
A study involving virtual rather than real patients was as effective in evaluating a medical device used to treat brain aneurysms, according to new research. The findings are proof of concept for what are called in-silico trials, where instead of recruiting people to a real-life clinical trial, researchers build digital simulations of patient groups, loosely akin to the way virtual…
A new paper on long-Covid describes persistent symptoms six months after acute Covid-19, even in young home isolated people. The study from the Bergen Covid-19 Research Group, which was published in the journal Nature Medicine, followed infected patients during the first pandemic wave in Bergen. "The main novel finding is that more than fifty per cent of young adults up to 30 years old,…
Dr. Hayder Amin and Dr. Caghan Kizil from the DZNE’s Dresden site aim to speed up developing drugs against brain diseases through cutting-edge technology. To this end, they are generating an innovative technology platform, termed “i3D-Markers”, based on high-density microelectrode arrays and 3-dimensional networks of human neurons. Compounds to be tested will be dripped onto this setup, and…
The idea of visiting the doctor’s office with symptoms of an illness and leaving with a scientifically confirmed diagnosis is much closer to reality because of new technology developed by researchers at McMaster University. Engineering, biochemistry and medical researchers from across campus have combined their skills to create a hand-held rapid test for bacterial infections that can produce…
Final results from a study of a blood test that can detect more than 50 types of cancer have shown that it is accurate enough to be rolled out as a multi-cancer screening test among people at higher risk of the disease, including patients aged 50 years or older, without symptoms. In a paper published in the cancer journal Annals of Oncology, researchers report that the test accurately detected…
After a stroke, doctors can try to remove clots in blood vessels to keep blood flowing freely to the brain. But even though most of these procedures are successful, less than half of people have a successful recovery from the stroke. A new study published in the medical journal Neurology sheds light on why that may be. The study found that trying more than once during a procedure to retrieve a…
Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping. The new "trimodal" approach combines…
Epstein-Barr virus (EBV) reactivation resulting from the inflammatory response to coronavirus infection may be the cause of previously unexplained long Covid symptoms—such as fatigue, brain fog, and rashes—that occur in approximately 30% of patients after recovery from initial Covid-19 infection. The first evidence linking EBV reactivation to long Covid, as well as an analysis of long Covid…
Statin use among patients with heart failure is associated with a 16% lower risk of developing cancer compared with non-statin users during an average of four years of follow-up. This is according to new research published in the European Heart Journal. In addition, the study found that statin use was associated with a 26% reduced risk of dying from cancer over the same period.
Researchers from the German Center for Infection Research (DZIF) at Charité – Universitätsmedizin Berlin and the University of Bonn have examined the way in which SARS-CoV-2 reprograms the metabolism of the host cell in order to gain an overall advantage. According to their report in Nature Communications, the researchers were able to identify four substances which inhibit SARS-CoV-2…
