07/09/2016Potential outbreaks of diseases such as Ebola and Lassa fever may be more accurately predicted thanks to a new mathematical model developed by researchers at the University of Cambridge. This could in turn help inform public health messages to prevent outbreaks spreading more widely.
06/09/2016BioPontis Alliance for Rare Diseases, a unique international nonprofit organization, and VIB, an excellence-based Life Science Research Institute in Belgium, announced a strategic partnership in rare diseases. The first program is aimed at developing a treatment for one type of Charcot Marie Tooth disease (CMT), a rare, progressive and invalidating neuropathy.
25/08/2016Bacteria that cause tuberculosis, leprosy and other diseases, survive by switching between two different types of metabolism. EPFL scientists have now discovered that this switch is controlled by a mechanism that constantly adapts to meet the bacterium's survival needs, like a home's thermostat reacting to changes in temperature.
18/08/2016Researchers discovered in the fruit fly a molecular "alarm clock" that tells resting ovules when is the right time to wake up. Defects in this alarm clock result in female fertility problems.
18/08/2016Mathematicians are now developing completely new statistical calculations on the world’s fastest computers in order to be able to predict how epidemics of dangerous hospital bacteria spread. Studying the entire genomes of bacteria has now thrown open entirely new possibilities for revealing their secrets. It is this genetic knowledge that scientists use to understand bacterial epidemics.
16/08/2016Brain scans have revealed how a genetic mutation linked to major psychiatric disorders affects the structure, function and chemistry of the brain.
08/08/2016Previous research has shown that sitting for an extended period of time at a computer or during a long airline flight reduces blood flow to the legs, which may contribute to the development of cardiovascular disease. Now, researchers from the University of Missouri have found that fidgeting while sitting can protect the arteries in legs and potentially help prevent arterial disease.
05/08/2016Using rats carefully bred to either drink large amounts of alcohol or to spurn it, researchers at Indiana and Purdue universities have identified hundreds of genes that appear to play a role in increasing the desire to drink alcohol.
02/08/2016Epilepsy is an extremely common disorder affecting people of all ages, from infants through teenagers to older adults. One of the most mysterious things about this disorder is that about 6 percent of the people with epilepsy have an unusually high incidence of sudden unexpected death.
08/04/2016A 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.
01/04/2016Human genetics is the study of the genetic makeup of human beings. DNA, chromosomes, and genes are extensively analyzed by medical specialists. Physicians of Germany need to have a qualification in genetic counseling to successfully advise patients.
22/02/2016Easy 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.
01/12/2015Multiple sclerosis apparently can strike anyone - regardless of age, family history, lifestyle or gender. Yet why then does it not strike everyone? Genetic and environmental factors appear not to be the only reason whether it develops or not. The countless microorganisms that colonize our intestinal tract could also be involved in this.
08/10/2015The many possibilities the Internet offers also don’t shy away from laboratory medicine. The demand for biochemical or genetic tests continues to rise. Next to standard laboratory tests, a market developed in which the patient is the immediate recipient of clinical results. New distribution channels eliminate the physician as the responsible party.
01/06/2015A 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.
04/05/2015There are many decisions to be made in an adult life; among them are cancer prevention screenings. They are voluntary and many people deliberate whether they should go or not and if they would actually want to know the results. Science, politics and health care professionals also ponder with each new preventive service whether it is beneficial and who should end up paying for it.
05/01/2015T-cells are the guardians of our immune system. When they show changes, it can lead to severe inflammatory responses in the body. It is believed that the T-cells in persons who are affected by inflammatory bowel disease don’t work properly. Two proteins that can be found on activated T-cells and that interact with each other are now being analyzed.
10/11/2014Sometimes 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.
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.
