Accumulation of amyloid beta and reduction of serotonin may trigger late-life depression

Looking for ways to image the human brain for the earliest signs of aging and cognitive decline, Johns Hopkins Medicine researchers recently identified a pattern that links the accumulation of amyloid beta (Aβ) proteins (associated with cognitive decline later in life) with a reduction of serotonin, the brain chemical that improves mood.

New imaging technology for detecting MALT lymphomas could save patients numerous gastroscopies

A new imaging technique for the detection of MALT lymphomas, malignant tumours of the lymphatic system, could probably save patients numerous gastroscopies. A study group of MedUni Wien achieved a high imaging accuracy by way of PET/MR and by using a PET Tracer directed against a certain cell receptor. The results are currently published in the top journal "Blood" of the American Society of Hematology.
