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…
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…
Extremely premature infants are at a high risk for brain damage. Researchers at the University of Vienna and the Medical University of Vienna have now found possible targets for the early treatment of such damage outside the brain: Bacteria in the gut of premature infants may play a key role.
Scientists from the German Cancer Research Center (DKFZ) and the Medical Faculty Mannheim, Heidelberg University, have identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.
A new mechanism that stops the progression of Huntington’s disease in cells has been identified by scientists at the University of Cambridge and University College London (UCL), as part of their research groups at the UK Dementia Research Institute. Researchers say the breakthrough study, published in Cell Reports, could lead to much needed therapies for the rare genetic disease, which is…
Researchers at Karolinska Institutet in Sweden can now report the results of a unique pilot project where drones were used to deliver defibrillators to real-life alerts of suspected cardiac arrest. The drones were dispatched in more than a fifth of the emergencies and arrived on target and ahead of the ambulance in most cases.
In a new study, researchers at Lund University and Uppsala University have seen a clear connection between how long a person sleeps and a number of biomarkers linked to cardiometabolic diseases such as cardiovascular disease and type 2 diabetes.
Scientists have grown beating heart cells to attempt to identify drugs to prevent Covid-19-related heart damage. Concerns over the extent of cardiac damage among Covid patients emerged during the coronavirus pandemic and there are also suggestions that the impact on cardiomyocytes could contribute to the symptoms of long Covid. To explore these issues, a research team at the University of…
People who work night shifts are at increased risk of developing an irregular and often abnormally fast heart rhythm called atrial fibrillation (AF), according to research published in the European Heart Journal. The study is the first to investigate the links between night shift work and AF. Using information from 283,657 people in the UK Biobank database, researchers found that the longer and…
A novel CT scan-based approach has revealed significant changes in a parameter indicating lung destruction in some asthmatics. This finding could lead to more personalized treatments for asthma accompanied by persistent airflow limitation. Clinicians have long thought that some people with asthma experience declines in their lung function, called fixed airflow obstruction (FAO), due to changes to…
Each wave of the pandemic has underscored just how contagious Covid-19 is, but there is less clarity among experts on exactly when—and to what extent—infected individuals are most likely to spread the virus.
Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in western countries, with an increasing incidence worldwide. Consequences of NAFLD can also include kidney disease and kidney stones, although the mechanisms for the development of these kidney complications as a result of NAFLD have not yet been fully explained. Researchers at the Leibniz Research Centre for Working…
A major UK clinical trial led by Queen’s University Belfast has shown how a new approach to reduce the use of mechanical ventilation can greatly improve outcomes for critically ill infants and children. The study, funded by the National Institute for Health Research (NIHR) Health Technology Programme, found that a greater involvement of nurses, minimising sedation use and increasing daily…
Obtaining two vaccine doses remains the most effective way to ensure protection against the Covid-19 Delta variant of concern dominant in the UK today, according to a study from the University of Oxford. Conducted in partnership with the Office of National Statistics (ONS) and the Department for Health and Social Care (DHSC), the study found that with Delta, Pfizer-BioNTech and Oxford-AstraZeneca…
Researchers at Tel Aviv University have 3D-printed a first-of-its-kind glioblastoma tumor that mimics a living cancer malignancy, powering new methods to improve treatment and accelerate the development of new drugs for the most lethal type of brain cancer. Glioblastoma is notoriously fatal as it accounts for the majority of brain tumors and is highly aggressive. The average survival time of…
A new study of patients with cerebral venous thrombosis (CVT) following Covid-19 vaccination provides a clearer guide for clinicians trying to diagnose and treat patients. The research, led by University College London (UCL) and UCL Health and published in The Lancet, is the most detailed account of the characteristics of CVT, when it is caused by the novel condition vaccine-induced immune…
For the first time, researchers at the Norwegian University of Science and Technology (NTNU) have shown how cancer cells reprogram themselves to produce lactic acid and to tolerate the acidic environment that exists around tumors. The finding could lead to a whole new direction for treating cancer. The breakthrough is the result of more than 13 years of work. The next step in research could…
Small aggregates of proteins known as Aβ oligomers are suspected as the main cause for the development of Alzheimer’s disease. However, it is not yet clear where and under what conditions these toxic aggregates form.
