A study of data from seven outpatient facilities in the New York region found that 20-24% of all the breast cancers diagnosed during an 11-year period were found in women age 18 to 49, according to research being presented today at the annual meeting of the Radiological Society of North America (RSNA).

For more than two decades, researchers at the University of Basel, Switzerland, have been investigating a severe form of muscular dystrophy in which muscles progressively degenerate. The research team has now discovered that the muscles’ ability to regenerate is also impaired. Future therapies should therefore aim not only to strengthen muscles but also to promote their regeneration.

An international team led by Goethe University Frankfurt, Germany, has used state-of-the-art cryo-electron microscopy to visualize electrical synapses (gap junctions) inside living cells. In doing so, they discovered a surprising additional structure: a previously unknown circular “cap” that is connected to the channel from the inside of the cell. It appears to be formed by the protein UNC-1, whose protein family is associated with various diseases. The results were published in Science Advances.

A new review in Chinese Medical Journal details progress in nanocarrier-based cancer therapy. It analyzes polymeric, lipidic, and other nanoplatforms, their roles in immunotherapy, chemotherapy, radiotherapy, and addresses translation challenges like scalability and biosafety.
