In a new study from SciLifeLab at Uppsala University, researchers have found a total of 141 regions (genes) in our genetic material that largely explain the genetic risk underlying asthma, hay fever and eczema. As many as 41 of the genes identified have not previously been linked to an elevated risk for these diseases. The results are published in the scientific journal Human Molecular Genetics.
Bacterial ribosomes need a single-stranded ribosome binding site (RBS) to initiate protein synthesis, whereas stable RNA structure blocks initiation. Paradoxically, structured mRNAs can nevertheless be efficiently translated. Researchers at Uppsala University have now elucidated the anatomy of a "standby" site and its requirements, to overcome RNA structure problems for translation.
The majority of women who undergo surgery for suspected ovarian cancer do not have cancer. A novel blood test developed by researchers at Uppsala University and University of Gothenburg, now offers the possibility of more precise diagnostics. This could lead to a reduction in unnecessary surgery and to earlier detection and treatment for affected women. (Communications Biology).
One key question in evolutionary biology is how novel genes arise and develop. Swedish researchers now show how new genes and functions that are advantageous to bacteria can be selected from random DNA sequences. The results are presented in the scientific journal mBio.
Both infants and their parents flexibly several behaviors to establish frequent episodes of joint attention. A new study shows that infants who are later diagnosed with autism seldom actively seek to establish such episodes themselves. This finding provides support for the view that children with autism have reduced social motivation already as infants.
Nearly ninety per cent of all cancer patient deaths are due to metastasis. A study from Uppsala University shows that a process that allows the cells to metastasise is aided by the synthesis of new ribosomes, the cell components in which proteins are produced. The results open the possibility for new treatment strategies for advanced cancers. The study is published in Nature Communications.
By 2050, around 70 per cent of the world’s children will live in cities. During the high-level meeting Uppsala Health Summit this autumn, international experts from different sectors will gather to discuss how to plan cities and strengthen public health strategies to better care for children’s health and wellbeing in all parts of the world.
High levels of polychlorinated biphenyls (PCBs) in the blood are associated with premature death. This is shown by a cross-disciplinary study, based on 1,000 randomly selected 70-year-olds in Uppsala, that is published in the JAMA Network Open journal today.
Many diabetes patients do not only have problems with their insulin, but also with the release of the hormone glucagon. Researchers at Uppsala University have now discovered a regulation mechanism which could provide an opportunity to improve blood glucose control in these patients. The research is published in the journal Diebetologia.
Should public health-care systems provide couples with expanded screening for genetic disorders before they decide to become pregnant? Screening programmes could increase our reproductive choices and autonomy. But there are ethical issues at stake.
Isolated human hepatocytes are essential tools in preclinical and clinical liver research, but cell quality is highly variable. Now, researchers from Uppsala University have devised a simple protocol that improves hepatocyte quality and enables cells from a wider quality spectrum to be used in standard and advanced cell culture. The findings are published in Archives of Toxicology.
Otherwise healthy men with advanced prostate cancer may benefit greatly from surgery, but many with this diagnosis have no need for it. These conclusions were reached by researchers after following a large group of Scandinavian men with prostate cancer for 29 years. The results are now published in The New England Journal of Medicine.
When deciding not to resuscitate patients in cardiac arrest, ethical issues arise. Nurses and physicians conflicting perspectives often cause frustration. In a new doctoral thesis from Uppsala University, Mona Pettersson examines clinical and ethical perspectives on “DNR orders” in cancer care.
Should researchers inform research participants, if they discover genetic disease risks in the participants? The value of complex genetic risk information for individuals is uncertain. In a PhD thesis from Uppsala University, Jennifer Viberg Johansson suggests that this uncertainty needs to be acknowledged by both geneticists and ethicists.
Why do some people comfortably walk between skyscrapers on a high-wire or raft the Niagara Falls in a wooden barrel whereas others freeze on the mere thought of climbing off escalators in a shopping mall? In a new study, scientists have found that a certain type of cells in the hippocampus play a key role.
To diagnose rheumatoid arthritis, antibodies to the amino acid citrulline are commonly measured. A new study from Uppsala University shows that a broad mix of different antibodies in the joints is the dominant factor that can be associated with severe inflammation and joint damage. These findings, published in Annals of the Rheumatic Diseases, may eventually lead to improved diagnostics.
The challenges of future cancer care are in focus when Uppsala Health Summit 2018 opens next week. The annual summit will be attended by important international actors from health organisations, academia, industry, civil society and policy organisations.
Uppsala University, Uppsala University Hospital and the European Infrastructure for Translational Medicine (EATRIS) have formed a collaboration with GlaxoSmithKline (GSK) to deliver a clinical and scientific expert network for the development and application of innovative imaging methods for inflammatory diseases.
In a new study, researchers at Uppsala University and other institutions have identified genetic material from the recently identified Alkhurma hemorrhagic fever virus in the tick species Hyalomma rufipes. The discovery was made after thousands of ticks were collected from migratory birds . The results indicate that birds could contribute to spreading the virus to new geographical areas.
The number of people who fall ill with cancer is increasing globally. While medical advances open up unprecedented opportunities for slowing down and treating cancer, the gap between what is medically possible and what healthcare can provide is constantly growing. Ahead of Uppsala Health Summit, 14–15 June, the report Care for Cancer was published today, focusing on future diagnostics and care.
