Researchers at the DZNE and the University Medical Center Göttingen (UMG) have identified molecules in the blood that can indicate impending dementia. Their findings, which are presented in the scientific journal “EMBO Molecular Medicine”, are based on human studies and laboratory experiments. Various university hospitals across Germany were also involved in the investigations.
Hope for a future without fear of Covid-19 comes down to circulating antibodies and memory B cells. Unlike circulating antibodies, which peak soon after vaccination or infection only to fade a few months later, memory B cells can stick around to prevent severe disease for decades. And they evolve over time, learning to produce successively more potent “memory antibodies” that are better at…
“An artificial uterus – the incubator 2.0 – will become a reality within 10 years,” says Jasmijn Kok, one of the founders of Juno, a spin-off from the Eindhoven University of Technology, Netherlands. Together with researchers from the department of Industrial Design from the University, including her twin sister Lyla Kok, she wants to bring a technology that increases the chances of…
After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of Covid survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes surrounding the lung.
Researchers at the Centre for Genomic Regulation (CRG) and Pulmobiotics S.L have created the first ‘living medicine’ to treat antibiotic-resistant bacteria growing on the surfaces of medical implants. The researchers created the treatment by removing a common bacteria’s ability to cause disease and repurposing it to attack harmful microbes instead.
Researchers at Karolinska Institutet have examined long-term outcomes in patients who received pacemaker implantations after transcatheter aortic valve replacement (TAVR) through their groin. The result showed no significant difference in mortality for the patients with pacemakers compared to those without. The study is published in the journal JACC: Cardiovascular Interventions.
Many of the organ systems found in animals exhibit highly complex structures, which are essential for their various functions. How such structures develop during embryonic development is a central question in biology. Physicists led by Erwin Frey (Professor of Statistical and Biological Physics at LMU Munich) and Andreas Bausch (Professor of Cellular Biophysics at the Technical University of…
The Nobel Prize in Physiology or Medicine 2021 was awarded jointly to two scientists who made important discoveries regarding our receptors for temperature and touch. Our ability to sense heat, cold and touch is essential for survival and underpins our interaction with the world around us. In our daily lives we take these sensations for granted, but how are nerve impulses initiated so that…
Researchers at the University of Southampton have invented a new way to generate human cartilage tissue from stem cells. The technique could pave the way for the development of a much-needed new treatment for people with cartilage damage. Cartilage acts as a shock absorber in joints, but it is susceptible to damage through daily wear-and-tear, or trauma from sports injuries and falls.
Research led by the Queensland University of Technology (QUT) on the interaction between prostate cancer cells and the tumour microenvironment has shed more light on the propensity of some types of prostate cancer to metastasize to bone more readily than other types.
Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers at the University of Zurich (UZH) and University Hospital Zurich (USZ) have found. Their findings will now be tested in…
If the suspicion of Alzheimer's disease creeps up, those affected must prepare themselves for lengthy and complex procedures until the case is clear. A team from Empa and the Cantonal Hospital of St. Gallen is now in the process of developing a blood test that will enable a reliable diagnosis using atomic force microscopy (AFM).
When it comes to getting healthy and reducing mortality risk, increasing physical activity and improving fitness appear to be superior to weight loss.
Hokkaido University scientists and colleagues in Japan have found a way that could help some patients overcome resistance to an immunotherapy treatment for cancer. The approach, proven in mice experiments, was reported in the Journal for Immunotherapy of Cancer.
In the fight against diseases like amyotrophic lateral sclerosis (ALS), biomedical engineering researchers at the University of Southern California have created a powerful lab model to better see how our muscles and neurons connect.
Over the past decade, scientists have been exploring vaccination as a way to help fight cancer. These experimental cancer vaccines are designed to stimulate the body’s own immune system to destroy a tumor, by injecting fragments of cancer proteins found on the tumor.
By analysing secondary acute myeloid leukaemias, researchers at the Institute for Research in Biomedicine (IRB) Barcelona have detected mutations caused by platinum-based chemotherapies in cells that were healthy at the time of treatment. Treatment with chemotherapies influences the development of blood cells, favouring clonal hematopoiesis from cells with pre-existing mutations. The study has…
A team led by the Garvan Institute of Medical Research has revealed a new approach for classifying breast cancer subtypes based on their cell profile, which could help personalise treatments for patients. By analysing breast cancer biopsies from patients at Sydney hospitals, the researchers revealed more than 50 distinct cancer, immune and connective cell types and states, which could assign…
Researchers at Umeå University now demonstrate a method by which specific cell types in human organs can be studied with micrometer precision. The method can be used to reveal previously unrecognised alterations in the pancreas, but it can also be used to study other human organs and diseases.
Colourful, 3D rendered scientific images are fascinating - but can they deceive viewers? New research from Spain suggests this might be the case. According to the study by the Instituto de Radio Televisión Española and the Universitat Autònoma de Barcelona conducted during the Covid-19 lockdown, black and white images of SARS-CoV-2 make the virus seem more infectious. The results, published on…
Some blood lipid biomarkers linked to cardiovascular disease risk are also associated with a lower risk of amyotrophic lateral sclerosis (ALS) suggest the findings of a large epidemiology study. ALS is the commonest form of motor neuron disease - a progressive nervous system disease that destroys nerve cells responsible for voluntary movement such as walking and talking.
Common medications can accumulate in gut bacteria, a new study has found, altering bacterial function and potentially reducing the medications’ effectiveness. These interactions - seen for many drugs including those used to treat depression, diabetes, and asthma - could help researchers to better understand how drug effectiveness and side-effects differ between individuals. The study is…
A new technology that can study which therapies will work on patients with solid cancerous tumours has been developed by scientists at University College London (UCL). Researchers say the tool, which can rapidly test tumorous tissue against different treatments, such as chemotherapy, immunotherapy or radiotherapy, could be used by clinicians to pinpoint the best therapy for a particular patient.
Covid-19 infection does not appear to affect the lung function of young adults, according to new research presented at the ‘virtual’ European Respiratory Society International Congress. In the first study to investigate the impact of Covid-19 infection on lung function, researchers led by Dr Ida Mogensen, a post-doctoral fellow at the Karolinska Institute, Stockholm, Sweden, found that even…
Researchers at the University of Helsinki could show for the first time that normal human fibroblast cells can be converted to specific cancer cells using only factors that are commonly detected in actual human patients. Previous studies have achieved this only by using powerful viral factors that are not common in human cancers. Since many human cancer types still lack specific diagnostic…
