Joint cartilage usually regenerates very poorly. The matrix of cartilage (scaffolding) contains very few cells in deep layers. Moreover, joint cartilage is highly isolated: there are neither regenerative cells in the immediate vicinity that could migrate into the site of the defect and trigger repair, nor vessels that could transport regenerative cells to the cartilage. Unsurprisingly,…
Researchers at ZHAW Zurich University of Applied Sciences are working with the Swiss company Osmotex AG to develop a self-disinfecting mask that inactivates viruses at the push of a button. The prototype of this mask made of electrochemical textiles shows an antiviral effect of over 99 percent. Further applications such as sterilizable seat covers are being examined.
The impact of Covid-19 in Africa has been vastly underestimated, warn researchers in a new study. Outside of South Africa, this is the first study to provide systematic surveillance data capturing the impact of Covid-19 in Africa. Their findings are based on polymerase chain reaction (PCR) test results for 364 deceased people of all ages at the University Teaching Hospital morgue in Lusaka,…

A team of researchers studying the effectiveness of different types of face masks has found that in order to provide the best protection against Covid-19, the fit of a mask is as important, or more important, than the material it is made of. The researchers, from the University of Cambridge, carried out a series of different fit tests, and found that when a high-performance mask – such as an…
Research into 3D bioprinting has grown rapidly in recent years as scientists seek to re-create the structure and function of complex biological systems from human tissues to entire organs. The most popular 3D printing approach uses a solution of biological material or bioink that is loaded into a syringe pump extruder and deposited in a layer-by-layer fashion to build the 3D object. Gravity,…
Inhibiting a key enzyme that controls a large network of proteins important in cell division and growth, paves the way for a new class of drugs that could stop glioblastoma, a deadly brain cancer, from growing. Researchers at Princess Margaret Cancer Centre, the Hospital for Sick Children (SickKids) and University of Toronto (U of T), showed that chemically inhibiting the enzyme PRMT5 can…
Is there a better approach to Covid drug research? Research from the University of Kent, Goethe-University in Frankfurt am Main, and the Philipps-University in Marburg has provided crucial insights into the biological composition of SARS-CoV-2, the cause of Covid-19, revealing vital clues for the discovery of antiviral drugs. Researchers compared SARS-CoV-2 and the closely related virus SARS-CoV,…
Researchers at the University of Maryland School of Medicine (UMSOM) and their colleagues published a new analysis from genetic sequencing data of more than 53,000 individuals, primarily from minority populations. The early analysis, part of a large-scale program funded by the National Heart, Lung, and Blood Institute, examines one of the largest and most diverse data sets of high-quality whole…
With two commercially available inhibitors, the cell cycle of the cancer cells in neuroblastomas can be disrupted at a key point causing tumour cell death. Neuroblastomas are malignant solid tumours that occur mainly in early childhood. Inhibiting the MYCN oncogene or its function could be a promising therapeutic opportunity.
University of Minnesota Medical School researchers studied SARS-CoV-2 infections at individual cellular levels and made four major discoveries about the virus, including one that validates the effectiveness of remdesivir – an FDA-approved antiviral drug – as a form of treatment for severe Covid-19 disease. “Since the start of the Covid-19 pandemic, the way that each individual responds…
Wearable devices can identify Covid-19 cases earlier than traditional diagnostic methods and can help track and improve management of the disease, Mount Sinai researchers report in one of the first studies on the topic. The findings were published in the Journal of Medical Internet Research. The Warrior Watch Study found that subtle changes in a participant’s heart rate variability (HRV)…
In a recent study, researchers at the Texas A&M University have described a new process to purify astatine-211, a promising radioactive isotope for targeted cancer treatment. Unlike other elaborate purification methods, their technique can extract astatine-211 from bismuth in minutes rather than hours, which can greatly reduce the time between production and delivery to the patient.
A way of using machine learning to more accurately identify patients with a mix of psychotic and depressive symptoms has been developed by researchers at the University of Birmingham. Patients with depression or psychosis rarely experience symptoms of purely one or the other illness. Historically, this has meant that mental health clinicians give a diagnosis of a ‘primary’ illness, but with…
Providing the blind with visual impressions: That is the aim of the I See project, in which neuroscientists from the University of Bremen are involved. The approach: A miniature camera collects visual information and translates it into signal patterns that are transferred to brain implants.
Global greenhouse gas emissions over the last century have made southern China a hotspot for bat-borne coronaviruses, by driving growth of forest habitat favoured by bats. A new study published in the journal Science of the Total Environment provides the first evidence of a mechanism by which climate change could have played a direct role in the emergence of SARS-CoV-2, the virus that caused the…
Researchers from the University of Nottingham have discovered a novel antiviral property of a drug that could have major implications in how future epidemics/pandemics – including Covid-19 – are managed. The study, published in Viruses, shows that thapsigargin is a promising broad‑spectrum antiviral, highly effective against SARS-CoV-2, a common cold coronavirus, respiratory syncytial virus…
USC researchers have developed a new method to counter emergent mutations of the coronavirus and hasten vaccine development to stop the pathogen responsible for killing thousands of people and ruining the economy.
A study reveals that scalp cooling physically protects hair follicles from chemotherapy drugs. It is the world’s first piece of biological evidence that explains how scalp cooling actually works and the mechanism behind its protection of the hair follicle. The data was part of an innovative hair follicle research project carried out by the dedicated Scalp Cooling Research Centre based at the…
Over 23 million people around the world suffer from heart failure. The disease is usually treated with a transplant, but because donated hearts are hard to come by, there is an ongoing need for alternative therapies. With new developments in cardiac assistance systems, we can delay the need for a transplant – or even eliminate it altogether,” says Professor Yves Perriard, head of EPFL’s…
Cancer ranks as a leading cause of death in every country in the world, and, for the first time, female breast cancer is the most commonly diagnosed cancer, overtaking lung cancer, according to a collaborative report, Global Cancer Statistics 2020, from the American Cancer Society (ACS) and the International Agency for Research on Cancer (IARC). Data show that 1 in 5 men and women worldwide…
Covid-19 patients who suffer a cardiac arrest either in or out of hospital are far more likely to die than patients who are not infected with the coronavirus. In particular, women have the highest risk of dying: they are nine times more likely to die after suffering a cardiac arrest in hospital, according to research published in the European Heart Journal.
Engineers at EPFL’s Center for Artificial Muscles have developed a silicone aorta that can reduce how hard patients’ hearts have to pump. Their breakthrough could offer a promising alternative to heart transplants. “Over 23 million people around the world suffer from heart failure. The disease is usually treated with a transplant, but because donated hearts are hard to come by, there is an…
The continuing corona virus epidemic has impacted strongly on cancer care and research, including the delay of treatments and diagnoses as well as on trials of new therapies, and the shift in research to develop a Covid-19 vaccine. However, the session ‘Cancer research and Covid-19’, during the National Cancer Research Institute (NCRI) Virtual Showcase (online 2-3 November) looked at how UK…
