Detailed images of illness, death and cancelled activities; these were some of the common themes of children’s drawings during the COVID-19 pandemic. A new study from Uppsala University, in which researchers studied 91 drawings made by children aged between 4 and 6, shows that the pandemic affected the children significantly and that they had extensive knowledge about the disease.
A research group at Uppsala University has developed a simple and effective artificial blood-brain barrier model that can be used to determine how well antibody-based therapies can enter the brain. Today animal experimentation is the most common method for testing an antibody’s function and the new model could reduce the need for animal testing.
On 23 February the Deputy Secretary-General of the United Nations, Amina J Mohammed, will give the Dag Hammarskjöld lecture in Uppsala. The lecture is open to the public.
The use of broad-spectrum antibiotics increased drastically in intensive care at the beginning of the Covid-19 pandemic. At first, this helped patients and seemed to prevent the growth of most bacteria. However, it also contributed to a sharp growth in enterococci, an antibiotic-tolerant group of bacteria, which rendered the treatment of urinary tract infections more difficult.
Thanks to a new prognostic method for detecting cancers including cancer of the large intestine, doctors could provide clearer disease prognoses and predict which patients will respond best to immunotherapy. The method consists of a combination of two types of immune cells that characterise certain forms of cancer. This has been shown in a new study published in the journal eBioMedicine.
The earlier infants begin to taste small samples of solid food, the earlier they eat more food and stop breastfeeding. This is shown in a new study from Uppsala University and Sophiahemmet University, in which the mothers of 1,251 infants from all over Sweden participated. Almost half of the infants received tastings at the age of four months.
Bacterial perseverance is a new phenomenon that helps explain how bacteria adapt to survive antibiotic treatments. A group of researchers at Uppsala University have studied how individual bacteria react when exposed to different antibiotics. The result underlines the importance of adhering strictly to antibiotic prescriptions.
A new study from researchers at Uppsala University presents novel findings on why human lymph nodes lose their function with age and the consequences for the effectiveness of our immune system. The article has been published in The Journal of Pathology.
Researchers at Uppsala University have shown that Scandinavian wolves carry around 100,000 harmful mutations in their genome. As long as the harmful mutations can be compensated by a healthy genetic variant, this does not need to pose a problem. However, as there has been a high level of inbreeding in the wolf population, the occurrence of double harmful variants has increased with each generation
Men are at an increased risk of a severe bout of COVID-19 compared to women. Researchers at Uppsala University have now shown that this may be due to loss of the Y chromosome in part of their white blood cells. The findings could eventually be used to assess the risk of developing severe COVID-19 and perhaps to improve treatment.
Using new gene mapping methods, researchers have found connections between atopic dermatitis in dogs and several regions of the genome. Some genes identified coincide with genes linked to similar problems in humans. The filaggrin gene region, for example, which is regarded as the most powerful risk factor for atopic eczema in humans, has now also been linked to this disease in Labrador retrievers.
Researchers at Uppsala University have discovered and characterised a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.
