A Brazilian study published April 26 in the journal Cancer Research shows for the first time in vivo that Zika virus can be used as a tool to treat aggressive human central nervous system (CNS) tumors. After injecting small amounts of the pathogen into the brains of mice with an advanced stage of the disease, the scientists observed a significant reduction in tumor mass and an increase in survival. In some cases, the tumor was completely eliminated, even where the disease had metastasized to [...]

Scientists from the Babraham Institute near Cambridge in collaboration with colleagues from Brazil and Italy have discovered a way that good bacteria in the gut can control genes in our cells. The work, published January 9 in Nature Communications, shows that chemical messages from bacteria can change the location of key chemical markers throughout the human genome. By communicating in this way, the bacteria may help to fight infections and to prevent cancer. This work, led by Dr. Patrick [...]

Researchers at the University of São Paulo (USP), in Brazil, are testing a technique in mice that combines low-intensity electric current with a formulation containing nanoencapsulated chemotherapy to treat skin cancer. Applying a low-intensity unidirectional current is one of the ways to ensure that chemical substances penetrate the skin, pushed into the bloodstream through the electric field using a technique known as iontophoresis. According to preliminary results of the study, [...]
