The new combination of drugs was developed by Professor Peter Kremsner of the Tübingen Institute of Tropical Medicine and the company DMG Deutschen Malaria GmbH.
25/01/2018Researchers have long wondered how our cells navigate inside the body. Two new studies, in which Lund University researcher Pontus Nordenfelt has participated, have now demonstrated that the cells use molecular force from within to steer themselves in a certain direction. This knowledge may be of great significance in the development of new drugs.
23/01/2018Scientists from VIB-UGent have discovered insights for a possible new therapy for eczema that also reduces the severity of asthma. The findings are an important next step in understanding the relationship between the two inflammatory diseases and to developing effective therapies. The results of the study are published in the Journal of Investigative Dermatology.
19/01/2018Osaka University study identifies antibody that alleviates symptoms in neuromyelitis optica in rats.
18/01/2018A paper just published in "Nature Biotechnology" outlines a pioneering method of screening a person's diverse set of antibodies for rapid therapeutic discovery. Antibody proteins are an important part of the human immune system that specifically target foreign viruses and bacteria, and they have been the fastest-growing class of approved drugs in the past several decades.

01/08/2017Many therapeutic drugs are very powerful, but they are also very toxic at the same time. Thus, they have to be measured regularly, again and again, so that an adjustment of the individual drug dosage can be made. Until now, the "normal" way was to take the blood sample, send it to a central laboratory and get the results after some days. A new point-of-care test can measure it in 15 minutes.
01/12/2016A German proverb says, "Old age is like a hospital that accepts all diseases," and medicine confirms that older people are not only considerably more susceptible to infectious diseases than they were in middle age, but that body and mind are also less resilient and recover slower or not at all from adverse effects or injuries.
04/01/2016Most Europeans think it was a long time ago, but the residents of West Africa clearly feel the consequences of the Ebola epidemic that broke out in December 2013 and still continues today. So far, approximately 11,300 people have died as a result of the outbreak; more than 28,000 contracted the disease.
01/12/2015Each year, approximately 250,000 Germans suffer a stroke. This makes stroke the third leading cause of death after heart disease and cancer. The circulatory disorder that occurs in the brain is normally treated using systemic thrombolysis, a procedure that bears various risks. Unlike mechanical thrombectomy, which offers clear advantages by comparison.
03/08/2015Endoradiotherapy can be very unpleasant for cancer patients, since it does not only harm tumor cells, but also healthy ones. Sometimes, patients even need to stop therapy because of the side effects. Physicians and researchers are thus continuously searching for ways to transport radiopharmaceuticals directly and exclusively to their target.
03/08/2015Malignant tumors can be fought with X-rays – usually with radiation therapy from outside the body. Nuclear medicine physicians can also accomplish this inside the body with radioactive materials, called radiopharmaceuticals. They also offer big benefits for clinical diagnostics as long as a specific target can be assigned to them.
01/07/2015Deep vein thrombosis is not just a risk factor for frequent flyers but also for wearers of cardiovascular implants and newly operated patients. Blood thinners prevent these dangerous blood clots from forming, but they need to be carefully adjusted and do not work the same way in every patient. A detailed analysis of platelets (thrombocytes) could prevent complications in the future.
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.
01/12/2014Several weeks ago on November 1, 2014, 29-year-old Brittany Maynard, who suffered from terminal brain cancer, took drugs to end her life surrounded by her family. This was preceded by months of despair and anguish, but also by love and a lust for life as the young woman describes in several videos she recorded to fight for the right to die with dignity.
