How the lungs of premature babies can undergo damage

09/10/2017

Premature babies that need ventilation to support their breathing often suffer from a condition known as bronchopulmonary dysplasia. Researchers at the Helmholtz Zentrum München, partner in the German Center for Lung Research (DZL), have now discovered a molecular mechanism that plays a key role in the development of the disease.

Metabolism can be used to subtype hepatoblastoma tumors

19/09/2017

Looking at cell metabolism instead of histology, EPFL scientists have identified new biomarkers that could help more accurately classify the two main subtypes of hepatoblastoma, a children liver cancer. Hepatoblastoma is a rare pediatric liver cancer, usually diagnosed in the first three years of life.

A hair-trigger for cells fighting infection

19/09/2017

To fight infections cells in the immune system play a dangerous game with their own genes. Damaging genes allows B cells to make antibodies that are specifically equipped to target to specific causes of illness, but damaging genes also puts them at risk of becoming cancerous.

New receptor found on scavenger cells

08/09/2017

Adenoviral infections have a mild disease progression in healthy people, but it can be dangerous for immunocompromised people. If a patient is infected with the virus and gets a bacterial infection on top of it, it can lead to an excessive inflammatory response known as a cytokine storm, an overreaction by the immune system leading to high concentrations of proteins that promote inflammation.

From cancer evolution to personalized therapies

24/08/2017

Being able to predict the resistance or sensitivity of a tumour cell to a drug is a key success-factor of cancer precision therapy. But such a prediction is made difficult by the fact that genetic alterations in tumours change dynamically over time and are often interdependent, following a pattern that is poorly understood.

Study offers new targets for drugs to treat fatty liver disease and liver cancer

23/08/2017

There may be no silver bullet for treating liver cancer or fatty liver disease, but knowing the right targets will help science develop the most effective treatments. Researchers in Sweden have just identified a number of drug targets that can be used in the development of new efficient treatment strategies with minimum side effects.

Prenatal diagnosis: genetic analysis using droplet PCR

24/07/2017

A new analysis method that uses fetal DNA extracted from the mother’s blood is designed to non-invasively reach a prenatal diagnosis of genetic disorders in a child. A task force of the Hahn Schickard Society for Applied Research is an active part of the "ANGELab" project and co-developed this diagnostic procedure.

Pneumonia in Children: Ultrasound or X-Rays?

08/03/2017

Pneumonia is the most frequent respiratory disease in children and can even cause death. That is why it is extremely important to make an accurate diagnosis as quickly as possible. If this requires imaging tests, normally X-rays are taken. But there is an alternative: ultrasound.

Collect Data? Utilize Data! – The Blessings of Big Data

01/03/2017

Genome data, MRI images, and blood test results – data collected in the medical sector is not only very heterogeneous but also extremely extensive. However, it is important to not only collect this data but to also utilize it. After all, processed, linked and analyzed data provides many opportunities in research, hospital management and ultimately also for the individual patient.

Diabetes: comprehensive prevention, early "vaccination"?

08/04/2016

A diagnosis of diabetes often catches new patients off guard - for instance if they end up in the emergency room suffering from metabolic decompensation. Children are often affected by this. Their immune system destroys the insulin-producing cells in the pancreas early on in their lives, thus causing type 1 diabetes.

Point-of-care-testing: from disc to diagnosis

22/02/2016

Easy solutions that deliver results quickly are a great asset in medicine: patients receive their diagnosis faster and physicians have more time to treat them. Such tools also work without sophisticated resources and trained personal. A device currently developed in a project funded by the European Commission could bring all of this to point-of-care-testing for infectious diseases.

Cancer Immunotherapy: Individual mutations as new target structures

01/06/2015

A tumor is as unique as the person who is affected by it. For a long time, it was assumed this would make treatment more difficult since cancer drugs are not able to be one hundred percent effective in targeting the affected cells. In this interview with MEDICA.de, Professor Ugur Sahin explains why it is precisely these individual mutations that make him hopeful for a new type of therapy.

Genetics: “We try to simplify diagnosis for rare diseases“

10/11/2014

Sometimes your TV is actually right and diagnosing an illness is really a puzzle. This is the case with rare diseases for example, which only affect a small portion of the population. Physicians are then confronted with the problem of not having enough experience with a specific illness and its symptoms to be able to make a diagnosis.

Vascular health in athletes

02/06/2014

"Sports are good for your health", as the saying goes. Regular exercise promotes the health of our blood vessels and prevents vascular diseases. However, many years of competitive sports can also have negative effects on vascular health and increase the risk of myocardial infarction. Prof. Martin Halle of the Technical University Munich explains at MEDICA.de what athletes need to pay attention to.
