New strategy improves outcome for children with most common type of brain tumor
...e of chemotherapy, and a reinfusion of bone-marrow stem
cells after each cycle of chemotherapy. Children with high-risk medulloblastoma have a 3040% chance of surviving to 5 years, and chemotherapy usually lasts for about 12 months. By using their risk-adapted approach to radiotherapy, Dr Gajjar and co...
Combined therapies may boost immune response and long-term protection against brain tumors
...he researchers injected bone marrow-derived neural stem
cells that were genetically engineered to produce IL-23. The stem
cells tracked tumor cells and the IL-23 produced an immune response and long-term protection. In th...

Irrational decisions driven by emotions

from an ability to override automatic emotional responses, rather than an absence of emotion per se. It has long been assumed in classical theories of economics that people act entirely rationally when taking decisions. However, it has increasingl...
