What could heart surgery possibly have in common with ship design? Apparently quite a lot. A team of researchers from the Foundation for Cardiac Surgery Development in the southern city of Zabrze has built a prototype of a cutting-edge biological heart valve to help patients with ailing hearts. The researchers, headed by Dr. Piotr Wilczek, have succeeded because they teamed up in the project with experts from different research institutions, including the Ship Design and Research Center (CTO) in the northern city of Gdańsk, which helped them understand the intricacies of how the blood flows through the organs. The researchers were also helped by the Zabrze-based Silesian Center for Heart Diseases, which specializes in the treatment of cardiovascular conditions.
Researchers from the Foundation for Cardiac Surgery Development in the southern city of Zabrze have used tissue engineering technology to develop a new type of biological heart valve. The valves are called biological because the patients themselves are the source of cell material used in them.

Cells of malignant brain tumors deceive a patient’s immune system so effectively that it starts working for them. But this can also work the other way: researchers from the Nencki Institute of Experimental Biology in Warsaw have found a way to deceive brain tumors and transform malignant gliomas into benign forms.
Ozone is a colorless, odorless form of oxygen in the Earth’s atmosphere that plays an important role in protecting living organisms from the harmful effects of UV radiation from the sun.
A movement of the head and blowing air into a special tube are enough to move a wheelchair built by a young researcher from the Wrocław University of Technology in southeastern Poland. He is now working to upgrade his invention to make it more intuitive.

Prof. Wiesław L. Nowiński, a Singapore-based Polish researcher who has developed a range of three-dimensional atlases of the human brain that help doctors better diagnose brain diseases and plan neurosurgical procedures, talks to Danuta K. Gruszczyńska.
Your three-dimensional, highly accurate computerized atlases of the human brain can help doctors in making a diagnosis and in planning treatment. Can you tell us in more detail how they come in useful?
