A question of time
by University of Freiburg A team led by the Freiburg biologists Prof. Dr. Wolfgang Schamel and Prof. Dr. Wilfried Weber conducted an experiment in which they controlled the duration of the interaction of a specific protein with T cells, a type of white blood cells, thereby showing how the immune system differentiates between self and non-self molecules. The scientists published their results in the journal eLife. The function of the immune system is to distinguish between the body’s own cells...

Study reveals amyloid clumps of a truncated p53 structure related to endometrial cancer
by Instituto Nacional de Ciência e Tecnologia de Biologia Estrutural e Bioimagem (INBEB) Brazilian scientists identify the predominant presence of a truncated variant of the p53 protein in amyloid aggregates in endometrial cancer cells. Such structures are related to the progression of this tumor. A finding by Brazilian researchers promises new perspectives for the treatment of Type 2 endometrial cancer, the most aggressive form of one of the...

Clinical trial explores opening blood-brain barrier in fight against Alzheimer’s
by Ohio State University Medical Center A new clinical trial at The Ohio State University Wexner Medical Center and two other sites is testing an innovative procedure that may provide hope in the fight against Alzheimer’s disease. The non-invasive procedure uses low-intensity focused ultrasound to open the blood-brain barrier, a protective layer that protects the brain from infections or pathogens in the blood. However, this barrier also makes it nearly impossible to...

Mind-Machine Meld: How Computer-Assisted Telepathy Helps Humans Communicate
Communicating through your thoughts alone is possible — with a little technical assistance. Scientists at the University of Washington’s Center for Neurotechnology have figured out how to network human minds together to collaborate to move Tetris-like shapes on a computer screen using only thoughts. It works like this: Three players, including one main player, sit in separate rooms and...

Why visual stimulation may work against Alzheimer’s
Several years ago, MIT neuroscientists showed that they could dramatically reduce the amyloid plaques seen Alzheimer’sdisease in mice simply by exposing the animals to light flickering at a specific frequency. In a new study, the researchers have found that this treatment has widespread effects at the cellular level, and it helps not just neurons but also...

Sweating the Small Stuff
Posted Today Assistant professor of medical engineering Wei Gao is enriching the field of personalized and precision medicine with an abundant source of chemical data: sweat. Gao’s perspiration-analysis technology enables early detection of physiological aberrations, customized treatment plans, and greater accuracy in drug monitoring. Low energy, for example, is a symptom that could be associated with a multitude of...

Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia
JOHNS HOPKINS MEDICINE In a series of recently published studies using animals and people, Johns Hopkins Medicine researchers say they have further characterized a set of chemical imbalances in the brains of people with schizophrenia related to the chemical glutamate. And they figured out how to tweak the level using a compound derived from broccoli sprouts. They say the results advance...

Inhibition of ribosome biogenesis as a novel approach for multi-stage cancer treatment
by Uppsala University Nearly 90 percent of all cancer patient deaths are due to metastasis. A study from Uppsala University shows that a process that allows the cells to metastasise is aided by the synthesis of new ribosomes, the cell components in which proteins are produced. The results open the possibility for new treatment strategies for advanced cancers. The study...

Researchers identify previously unknown bacterial strain
by Johannes Angerer, Medical University of Vienna Clinicians at the Department of Neurology of MedUni Vienna/Vienna General Hospital identified muscle weakness and severe fatigue in a previously healthy patient, to the extent that he was soon confined to a wheelchair. These symptoms were indicative of the autoimmune disease myasthenia gravis. However, the treating neurologist, Matthias Tomschik,...
