New method unravels the mystery of slow electrons
New method unravels the mystery of slow electrons
Slow electrons are used in cancer therapy as well as in microelectronics. It is very hard to observe how they behave in solids. But scientists at TU Wien have made this possible. Electrons can behave very differently depending on how much energy they have. Whether you shoot an electron with high or low energy into a solid body determines which effects can be triggered.

Limited efficacy of common local anaesthetic
Liposomal bupivacaine was launched on the market twelve years ago to provide long-lasting local control of pain. The medication is used as a local anaesthetic, particularly for orthopaedic operations. A research study by MedUni Vienna has now shown the limited effectiveness of the substance. The study has just been published in the journal "Anesthesiology", the peer-reviewed journal of the American Society of Anesthesiologists (ASA).

Frequent salting of food increases the risk of stomach cancer
In Asian countries, where high-salt foods are popular, the link between high salt consumption and stomach cancer has already been proven. A long-term study by MedUni Vienna has now shown for the first time that this risk is also reflected in the cancer statistics in Europe. As the analysis recently published in the specialist journal "Gastric Cancer" shows, people who frequently add salt to their food are around 40 per cent more likely to develop stomach cancer than those who do not use the salt shaker at the table.

Immunotherapy for lung cancer effective even before surgery
Blocking "switches" of the immune system has revolutionized the treatment of patients with various metastatic cancers. In 2018, the discovery of this principle was recognized by the Nobel Prize in Medicine. An international research team has now shown that the simultaneous inhibition of two "immune switches", PD-1 and LAG-3, can lead to the killing of lung cancer cells after just a few weeks.

Underestimated risk of lung transplantation researched
PLS (Passenger Lymphocyte Syndrome) is a potentially life-threatening risk in lung transplants that has hardly been researched and is often underestimated in clinical practice. However, the complication occurs more frequently than previously thought, as shown by a recent study at the Department of Transfusion Medicine and Cell Therapy in collaboration with the Department of Thoracic Surgery at MedUni Vienna and University Hospital Vienna.

How healthy is the aronia berry?
How healthy is the aronia berry?
Aloe vera, chia, ginger, blueberries, avocado and the like: the title "superfood" has already been awarded to many foods. It stands for fruits, seeds, vegetables and more that are said to have a particularly health-promoting effect in one or more areas due to their ingredients. One of these superfoods was researched as part of a study at the Medical University of Graz by Sandra Holasek from the Department of Immunology at the Otto Loewi Research Center: the local aronia berry and its juice.

Genetic test for early detection of high cardiovascular risk
Genetic test for early detection of high cardiovascular risk
Clonal haematopoiesis is a phenomenon caused by mutations in haematopoietic stem cells and can lead to blood cancer. We now know that it occurs also in people with normal blood counts, where it is associated with an increased risk of life-threatening atherosclerotic cardiovascular disease. A research team at the Medical University of Vienna has now developed a genetic testing procedure to detect clonal haematopoiesis, which, when used in combination with an ultrasound examination of the carotid artery, allows to identify patients at high cardiovascular risk.

Immune cells in the starting blocks: 'Always ready' is hard work
Immune cells in the starting blocks: ’Always ready’ is hard work
When pathogens invade the body, the immune system must react immediately and prevent or contain an infection. But how do our immune cells stay ready when there is no attacker in sight? Scientists from Vienna and Salzburg have come up with an intriguing explanation: They are stimulated by healthy tissue.

Liver cancer: Molecular signalling pathway of tumour development decoded
Liver cancer: Molecular signalling pathway of tumour development decoded
As a malignant disease of the liver cells, hepatocellular carcinoma (HCC) is one of the main causes of cancer-related deaths. While the treatment options for this aggressive type of cancer remain limited, the incidence is increasing. A research team led by Latifa Bakiri and Erwin Wagner from MedUni Vienna's Clinical Institute for Laboratory Medicine has now described a molecular signalling pathway that plays a key role in the development of liver cancer, thereby identifying a potential new starting point for the development of therapeutic treatments.
