When scientific curiosity paves the way for improved healthcare: Read more about promising studies and trials that lead to more effective drugs, procedures as well as medical guidelines.
Researchers at the Catharina Heart and Vascular Center, together with Eindhoven University of Technology, have developed a new measurement method to analyze the smallest capillaries of the heart by measuring blood flow and resistance. The new method to assess coronary microcirculation allows cardiologists to make a clearer diagnosis. Until recently, the tests used for this purpose were not…
Scientists at Lausanne University Hospital (CHUV) and École polytechnique fédérale de Lausanne (EPFL) have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant. Their findings are published in the journal Cell Reports.
Researchers at Lund University in Sweden have developed a completely new stimulation method, using ultra-thin microelectrodes, to combat severe pain. This provides effective and personalised pain relief without the common side effects from pain relief drugs. The study, which was conducted on rats, has been published in the research journal Science Advances.
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…
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.
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.
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).
A study found that women who contract Covid-19 during pregnancy are at significantly higher risk of developing pre-eclampsia. In their study, researchers said their systematic review shows that women with SARS-CoV-2 infection during pregnancy had 62% higher odds of developing preeclampsia than those without the infection during pregnancy.
Researchers have found a possible explanation for why some patients recover much more poorly from brain injury if they later become infected.
Long COVID symptoms rarely persisted beyond 12 weeks in children and adolescents unlike adults.
Study suggests need for better ventilation and tight-fitting masks, in addition to widespread vaccination to help stop spread of the virus.
A two-minute passive-test that measures people’s brain waves in response to a series of images, 'Fastball EEG', could help expand early dementia diagnosis.
When it comes to getting healthy and reducing mortality risk, increasing physical activity and improving fitness appear to be superior to weight loss.
Researchers have found a way to defeat the multi-resistant bacterium Mycobacterium abscessus, a relative of the causes of tuberculosis and leprosy.
According to new research, vaccinated people are at greatest risk from severe Covid-19 leading to hospitalisation or death from 14 days post the second dose vaccination, when substantial immunity should be expected.
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.
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.
The study identified that a probable cause of Alzheimer's disease was the leakage from blood into the brain of fat-carrying particles transporting toxic proteins.
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.
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…
