How does scorpion poison detect brain cancer?

Glioma is considered the most dangerous type of brain tumor. Not only does it react poorly to conventional chemotherapy, it also hides well from scanners, spreading across a wide range of brain tissue. It seems that in the near future the treatment of this type of cancer will become a little easier – scientists have created a new type of tumor imaging, which causes cancer cells to "glow like a Christmas tree." The most interesting thing is that based on the technology lies an amino acid contained in the scorpion venom. To make the tumor more noticeable and highlight its facets for subsequent removal, researchers from Cedars-Sinai Medical Center used a compound called tosulehistid (BLZ-100). It is a synthetic variation of a peptide extracted from scorpion venom that easily binds to cancer cells in the brain. By adding a fluorescent dye to it, the researchers made it well visible with Continue Reading

Modified viruses prevent death from infectious disease

Many species of life-threatening bacteria are immune to antibiotics, and because of this, about 700,000 people die each year. Of course, researchers from all over the world are trying to develop new drugs, but the process has been going on for quite a while, while they have another, less proven method of treating infections – the use of viruses that eat bacteria. Recently, an experimental and extremely risky method helped save the life of a girl, whose probability of survival was less than one percent. How was the treatment? The girl who escaped imminent death was seventeen Isabelle Carnell Holdey. Even as a child, she suffered from chronic infection with Mycobacterium abscessus and from cystic fibrosis, a hereditary disease accompanied by damage to the endocrine glands and dysfunction of respiration. She underwent a lung transplantation, after which her condition worsened greatly: the infection was activated with double force, the liver Continue Reading
