A sleepless night not only leaves us fatigued and distracted, it also makes us interpret things more negatively and makes us more likely to lose our temper. Moreover, people suffering from a pollen allergy are at a high risk of some form of sleep disruption from the outset. This according to a new doctoral thesis from Karolinska Institutet that takes a neuroimaging approach to sleep loss.

The integration of the UN’s Agenda 2030 Sustainable Development Goals into higher education and the importance of engaging students in the process were in focus at the recent conference, “Rethinking Higher Education: Inspired by the Sustainable Development Goals”.

Diseases affecting mitochondria, the powerhouses of our cells, are often caused by mutations in the mitochondrial DNA. Symptoms of such mitochondrial diseases in mice can be ameliorated by increasing their levels of mitochondrial DNA, according to a study by researchers at Karolinska Institutet. The study is published in Science Advances and can, according to the researchers, lead to a novel treatment strategy for such mitochondrial diseases.

New study shows that patients with acute Achilles tendon rupture who undergo surgery within 48 hours experience a considerably better result with a smaller number of complications compared to patients who undergo surgery after 72 hours. Researchers at the group Orthopaedics, Department of Molecular Medicine and Surgery demonstrate this in a study recently published in The American Journal of Sports Medicine.

Hi Mats Hallgren, researcher at the Department of Public Health Sciences. You are first author of an article recently published in the British Journal of Psychiatry about links between sedentary behaviour and mental health. What are the most important results from the study?

The ERC Advanced Grant is one of the most prestigious funding programmes for research in Europe. Per-Olof Berggren, professor of experimental endocrinology at Karolinska Institutet, is now awarded this grant for the second time.

Hi there Guobin Su, doctoral student at the Department of Public Health Sciences at Karolinska Institutet. On Thursday 4 April 2019 you defended your thesis "Infections in patients with chronic kidney disease: patterns, outcomes and the role of vitamin D for future prevention". What is the main focus of your thesis?

More than 20 years ago an American research group released a spectacular idea that the red blood cell was capable of exporting the signaling molecule nitric oxide (NO) and by this mechanism participate in the classical physiological phenomenon known as hypoxic vasodilation, i.e. that our blood vessels automatically widen when oxygen levels become lower to ensure oxygen delivery to tissues (Jia Nature 1996).

We would like to welcome Annika Bolind Bågenholm to the Department of Learning, Informatics, Management and Ethics.

The survival rate among extremely preterm babies has greatly improved in Sweden, a country that offers top-class neonatal care, a study led from Karolinska Institutet published in the esteemed journal JAMA reports.

If a particular protein is missing during the fetal stage, no neurons develop that convey pain, temperature and itch, a study from Karolinska Institutet published in the journal Cell Reports shows. The discovery can eventually lead to new drugs for pain conditions.

Three researchers at Karolinska Institutet have been appointed Wallenberg Scholar in 2019: Ernest Arenas, Sten Linnarsson, and Randal S. Johnson. The researchers – among the foremost in their field in Sweden – receive SEK 18 million each from the Wallenberg Foundations in the form of a five-year grant for free research.

Researchers at Karolinska Institutet have traced the neurons that send projections to the medial prefrontal cortex in the mouse. The 3D location of the input neurons have been mapped throughout the brain.

Even premature babies carry anti-viral antibodies transferred from the mother, researchers at Karolinska Institutet in Sweden report in a paper on maternal antibodies in newborns, published in the journal Nature Medicine. The results should change our approach to infection sensitivity in newborns, they say.

Each year MedTech Magazine appoints the 100 persons who most affect and contribute to care, patients' health and the availability of medical technology to citizens and patients.

With the start of 2019, the Karolinska Genome Engineering facility (KGE) has opened its doors as a core facility for researchers from both within and outside of Karolinska Institutet and Karolinska University Hospital. The facility, led by Bernhard Schmierer, is located in Biomedicum 9B at the Department of Medical Biochemistry and Biophysics, and provides various gene editing services in cells.

PhD student Sara Causevic and researcher Helena Nordenstedt at the Department of Public Health Sciences and student Wiebke Mohr at the Department of Learning, Informatics, Management and Ethics started the Women in Global Health Sweden Chapter as a response to the Call to Action on Gender Equality.

Karolinska Institutet now facilitates for all educational programs to use digital examinations. Digital examinations are legally secure and efficient as well as allows for new possibilties for teachers and course administrators to develop the education programs.
