In a large international study, researchers at Uppsala University have identified DNA regions that are associated with physical activity or leisure screen time. The findings confirm that physical activity is beneficial for health and suggest that a more sedentary lifestyle can be explained by how muscles respond to exercise.
In the condition known as cerebral cavernoma, lesions arise in a cluster of blood vessels in the brain. In a new study from Uppsala University, researchers show that blood coagulation and blood clot formation are very relevant for the disease and that antithrombotic therapy may be beneficial for cavernoma patients.
Loss of the Y chromosome in blood cells of men is associated with disease and mortality, but no clear causal relationship has previously been identified. Now, researchers from Uppsala University show in the journal Science that loss of the Y chromosome in white blood cells causes development of fibrosis in the heart, impaired heart function and death from cardiovascular diseases in men.
Impaired hearing affects billions of people, but crocodiles, who live almost as long and can surpass 70 years of age, have good hearing throughout their lives. One reason is because can create new hair cells, and a research group from Uppsala University is now on the path to finding out why. Hopefully, knowledge from the world of crocodiles will be able to help people with impaired hearing.
Oral contraceptives and hormone therapy at menopause increase the risk of stroke. The increased risk is greatest during the first year of treatment and then declines. The study, which is now published in Stroke, is based on data from over a quarter of a million women from the UK Biobank database.
Researchers from the Zoonosis Science Center at Uppsala University have identified a new coronavirus. Their study of approximately 260 bank voles caught around Grimsö, Örebro County, shows that the virus is well established in Sweden’s red-backed voles. The finding has been published in the journal Viruses.
Although some rare genetic variants can increase the risk of disease markedly for a few individuals, the genetic contribution to common diseases is mostly due to a combination of many common genetic variants with small effects. This is shown in a comprehensive study by researchers at Uppsala University and SciLifeLab, published in the journal Nature Communications.
MS patients treated with Rituximab have better responses to the COVID-19 vaccine if they have higher B cell counts. This is the finding of a study from Uppsala University published in the journal JAMA Network Open. In patients with B cell counts of 40/µL (microlitres) or more, 9 of 10 patients developed protective levels of antibodies, while significantly fewer with lower counts had similar respon
A new study from Uppsala University shows that young adults when sleep-deprived evaluate angry faces as less trustworthy and healthy-looking. Furthermore, neutral and fearful faces appear less attractive following sleep loss. The findings are published in the scientific journal Nature and Science of Sleep.
Researchers at Uppsala University have detected different subgroups of the brain tumour form glioblastoma, where the cancer cells’ properties depend on which cell type they originate from. The used analysis method could also separate glioblastoma patients with significant differences in survival. The findings open up for identifying specific therapeutic targets for the new subgroups of glioblastom
In COVID Symptom Study Sweden more than 10 million daily reports from participants in COVID Symptom Study Sweden from April 2020 to February 2021. The scope of the study was to develop and evaluate a framework to estimate the regional prevalence of COVID-19 using symptom-based surveillance, and to test if these prevalence estimates could be used to predict subsequent trends in COVID-19 admissions.
Immunotherapy is increasingly becoming a successful way to treat cancer. Researchers at Uppsala University have now developed armed CAR-T cells that reinforce the immune defence against cancer and that could increase the possibilities to successfully treat solid tumours. The study has been published in the journal Nature BioMedical Engineering.
Support offered by a phone app can relieve post-traumatic stress and depression. A new study from Uppsala University’s National Centre for Disaster Psychiatry involving 179 patients shows that a dedicated PTSD app, PTSD Coach, helps adults suffering from mental health issues after traumatic events.
In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers at Uppsala University show in a new study that white blood cells and protein structures associated with the immune response infiltrate the vessel lesions.
By linking human population studies with experiments in cell and animal models, researchers have provided evidence that complex mixtures of endocrine disrupting chemicals impact children’s brain development and language acquisition. With their novel approach, the scientists show that up to 54 per cent of pregnant women were exposed to experimentally defined levels of concern.
Researchers at Uppsala University have discovered that the ancestors of legionella bacteria infected eukaryotic cells as early as two billion years ago. It happened soon after eukaryotes began to feed on bacteria. These results, described in a new study published in Molecular Biology and Evolution, also contributes to the chicken-or-egg debate about whether mitochondria or phagocytosis came first
Uppsala researchers have succeeded in designing a molecule that inhibits the replication of coronaviruses and that has great potential for development into a drug suitable for treating COVID-19. The molecule is effective against both the new variant and previously identified coronaviruses. The article has been published in the Journal of the American Chemical Society.
Although many people know what increases the risk of cardiovascular diseases, such as heart attacks, not everyone recognises their own risk factors. This is shown by a new study of 423 Swedes aged 40–70 years, which has now been published in the scientific journal Preventive Medicine Reports.
A new study, led by researchers at Uppsala University, shows that all individual patients suffering from severe COVID-19 may have lower oxygen requirements than was formerly believed. The study was conducted at a Swedish district hospital during the first wave of the pandemic in 2020. The scientists’ methods, as well as their results, may be useful for future planning of health care and resources.
In a new study, participants underwent an intense bout of exercise after both normal sleep and after three nights of curtailed sleep. When they exercised after curtailed sleep, the levels of the heart injury biomarker troponin increased slightly more, compared with when the participants performed exercise in their well-rested condition.
