Blood stem cells have a surprising ability. In addition to ensuring the continuous renewal of blood cells, they keep track of past infections so that faster and more effective immune responses can be triggered in the future.
More than one in four of the most viewed COVID-19 videos on YouTube in spoken English contains misleading or inaccurate information, reveals the first study of its kind, published online in BMJ Global Health. Public health misinformation on COVID-19 is reaching far more people than in previous pandemics and has considerable potential for harm, warn the researchers. While good quality accurate…
In a new study, researchers from the University of Copenhagen have discovered two important functions of a protein called RTEL1 during cell division. The researchers hope that the new knowledge will help to find new cancer treatments. One of the body's most important processes is cell division, which occurs throughout life. Normal cells only have a limited number of divisions, while in cancer…
As Covid-19 spreads throughout the country, much attention has been paid to the devastating effects of the virus on the lungs. But doctors are learning how the virus may affect other organs, including the brain. Some patients with Covid-19 have had neurological symptoms, which may include an increased risk of stroke.
A new analysis of the worldwide effort to sequence the coronavirus genome has revealed the scale of the genetic changes that are occurring in the virus known as SARS-CoV-2, as it spreads across the world. These changes have important implications for molecular diagnostics and potentially vaccine success. Led by the London School of Hygiene & Tropical Medicine, the research identified several…
Why does every person react differently to an infection with the coronavirus SARS-CoV-2? Why do some people have no symptoms or only mild symptoms of COVID-19, the disease which it causes? And why do some people become so severely ill that they require ventilators or even die? These questions are being investigated by Professor Mascha Binder, director of the Department of Internal Medicine IV at…
Single-cell RNA sequencing (scRNA-seq) has revolutionized the ability to characterize cell types and their gene expression programs in organisms and tissues.
Despite the use of personal protective equipment (PPE), reports show that many health care workers contracted the coronavirus disease (COVID-19), which raises substantial concerns about the effectiveness of the PPE.
A study of 4532 men in the Veneto region of Italy has found that those who were being treated for prostate cancer with androgen-deprivation therapies (ADT) were less likely to develop the coronavirus COVID-19.
In an international collaboration led by Lund University in Sweden, researchers have used synchrotron light to study what happens to the nerves in diabetes. The technique shows the 3D-structure of nerve fibers in very high resolution. “This knowledge can be used to map mechanisms for how nerve fibers atrophy and grow back. It means that we can better understand how diabetes affects the nerves…
One of the main features of colorectal cancer is that there are considerable differences between the tumors of individual patients - at genetic level and hence in terms of the response to treatment too. Researchers from the German Cancer Consortium (DKTK) have developed a method that allows these differences to be identified more effectively.
An ingenious necklace which detects abnormal heart rhythm will be showcased for the first time on EHRA Essentials 4 You, a scientific platform of the European Society of Cardiology (ESC). “The wearable necklace-ECG (electrocardiogram) provides a new and easy method for detecting an abnormal heart rhythm called atrial fibrillation, which is a fast-growing public health problem,” said study…
Using machine learning, a team of Western computer scientists and biologists have identified an underlying genomic signature for 29 different COVID-19 DNA sequences. This new data discovery tool will allow researchers to quickly and easily classify a deadly virus like COVID-19 in just minutes – a process and pace of high importance for strategic planning and mobilizing medical needs during a…
Our immune system not only protects us against infection, but also against cancer. This powerful protection is based in particular on the activation of special cells of the immune system, CD8+ T cells. These cells recognize infected or cancer cells and kill them specifically. “The ability of the immune system and especially CD8+ T cells to eliminate cancer cells in tissues such as the lung, gut…
Niels-Bjarne Woods, a researcher at Lund University in Sweden, has developed lung-specific mesenchymal stem cells to treat inflammation of the lungs and fibrosis. This research now may be the needed breakthrough for treatment of the severe respiratory issues related to COVID-19. A clinical study may soon be underway contingent on a successful application to the Swedish Medical Products Agency.…
The COVID-19 pandemic could, over the next year, lead to a 20% rise in the number of deaths from people who have been newly diagnosed with cancer, according to research supported by DATA-CAN. The analysis is the first to focus on the impact of the emergency on mortality rates in people with cancer and uses data from the health records of over 3.5 million patients in England.
Diabetes is called an incurable disease because once it develops, it does not disappear regardless of treatment in modern medicine. Having diabetes means a life-long obligation of insulin shots and monitoring of blood glucose levels. Recently, a research team at Pohang University of Science and Technology developed a wirelessly driven ‘smart contact lens’ technology that can detect diabetes…
Researchers at Karolinska Institutet and the University of North Carolina have mapped out the cell types behind various brain disorders. The findings are published in Nature Genetics and offer a roadmap for the development of new therapies to target neurological and psychiatric disorders.
Researchers in The University of Texas at El Paso’s (UTEP) Department of Chemistry and Biochemistry have developed a nanohybrid vehicle that can be used to optimally deliver drugs into the human body. The research was published in ACS Applied Materials & Interfaces. Leading the study are Mahesh Narayan, Ph.D., professor, and Sreeprasad Sreenivasan, Ph.D., assistant professor, both from the…
COVID-19 has infected millions and killed hundreds of thousands of people worldwide, but a new predictor model devised at the Queensland University of Technology (QUT) offers glimmers of hope, suggesting the worst has passed and indicating well under 1000 deaths for Australia. The team at QUT, led by physician, mathematician and Future Fellow Dan Nicolau, has developed what they believe to be a…
Susanne Hellmuth and Olaf Stemmann from the Chair of Genetics at the University of Bayreuth have discovered a natural protective mechanism that leads to the programmed death of potentially diseased cells.
A new way to deliver therapeutic proteins inside the body uses an acoustically sensitive carrier to encapsulate the proteins and ultrasound to image and guide the package to the exact location required, according to Penn State researchers.
A receptor in the cell layer that lines the blood vessels from the inside stimulates both the formation of new blood vessels in tumors and metastasis.
NEC Corporation announced analysis results from efforts using AI prediction platforms to design blueprints for SARS-CoV-2 vaccines that can drive potent T-cell responses in the majority of the global population. This initiative by the scientific teams within the NEC Group to help combat outbreaks of COVID-19 and support international vaccine development efforts is led by NEC OncoImmunity (NOI) in…
Two specific cell types in the nose have been identified as likely initial infection points for COVID-19 coronavirus. Scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that the COVID-19 virus uses to get into our cells. The identification of these cells by researchers from the Wellcome Sanger Institute, University Medical Centre Groningen,…
