In collaboration, researchers from two Russian universities have developed compounds that trigger programmable death in cancer cells and tested their efficiency on cervical tumor samples. The new compounds do not affect healthy cells, their toxicity being eight times lower than that of doxorubicin, a commonly used cancer treatment. This means that in the future, treatments using the new compound may help avoid the common side effects of chemotherapy.
ITMO Scientists Suggest New Synthesis Method For Nanoparticles Used in Cancer Treatment and Diagnostics
Researchers from ITMO’s ChemBio Cluster have suggested a new way of synthesizing magnetic nanoparticles for cancer treatment and diagnostics. Thanks to machine learning at the core of the new approach, the scientists can quickly select the properties of nanoparticles for efficient MRI diagnostics and hyperthermia treatment. With the new method, the synthesis of a single nanoparticle takes just a few seconds – compared to the hours required in the conventional experimental approach. The method was described in a paper published in Small.
Started by a single mutation in a cell, cancer is one of the leading causes of death worldwide that killed nearly 10 million people in 2020. In the article, Evgeniya Platonova, a Master’s student at ITMO’s SCAMT Institute, explains what cancer is and how it starts, and shares what medical advances are already helping to combat the disease.
Cancer is the second most common death cause in the world, which in 2020 took the lives of nearly 10 million people – every sixth death, according to WHO. Globally, researchers are developing new, more efficient treatments for oncological diseases. Scientists from ITMO also contribute to these efforts: recently, they have come up with a universally applicable magnetic particle from zinc ferrite and manganese ferrite that can facilitate both cancer diagnostics and treatment. The new method increases the efficiency of radiotherapy by 40%, and during magnetic hyperthermia it can heat cancer cells in several seconds, while also securing less exposure for the healthy cells. This study was published in Journal of Materials Chemistry B.
Ahmed Eldeeb decided to become a scientist when he was still at school. Though his family wanted him to pursue a career in engineering, medicine, or programming, the future researcher was so passionate about biotechnology and DNA/RNA technologies that, eventually, his dream brought him to ITMO University. Now the head of a frontier laboratory at the university’s SCAMT Institute, he develops DNA robots for cancer gene therapy and viral diagnostics. In this interview, Ahmed Eldeeb gives an insight into what it's like to build a lab from scratch and lead a team of 23 as a young PI.
In recent years, oncological diseases have become one of the most wide-spread causes of death in developed countries – and despite the abundant new diagnostics and treatment methods, fighting cancer is still a challenge. Nearly all known treatments have significant side effects, while some of them are even helpless against more persistent cancer cells. One solution to this problem is photothermal therapy, on its own or in combination with other treatments. Researchers from ITMO University have suggested a new method to treat melanoma more effectively and safely using gold nanoparticles. Read on to learn more about the new method.
From a next-gen toothpaste to a promising cancer treatment technology, as well as a new ecology-focused Master’s program and exciting academic mobility opportunities – there's lots going on in our science news digest for the second half of July. Let's dig in!
Neuroblastoma cells are used in the first stages of testing biocompatibility of nervous system drugs.
Scientists Propose New Nanoparticles That Can Potentially Be Used to Treat Cancer with Magnetic Fluid Hyperthermia
A group of Russian scientists have synthesized manganese–zinc ferrite nanoparticles that can potentially be used in cancer treatment. Due to their unique magnetic properties, the particles can serve as deactivators of affected cells while having almost no negative impact on healthy tissues. The results have been published in the Journal of Sol-Gel Science and Technology.
