Cure cancer by " reprogramming " immune cells

Researchers from the US National Cancer Institute have invented a special method to activate the process of self-destruction of cancer cells.

According to Professor Paul Hergenroter, the author of the invention, doctors initially sought to take immune cells - called T-lymphocyte - of a person whose body is specifically able to heal itself. Skin melanoma (a type of cancer consisting of small tumors that are dark in the skin).

From these T-lymphocytes, scientists have identified the types of genes that can identify cancer cells and replicate the gene. Later, the new gene was transplanted into immune cells taken from patients with melanoma. After patients undergo a round of chemotherapy, they will be re-implanted ' corrected ' immune cells with new genes. As a result, after 18 months, many patients had no cancer cells in them.

Wireless artificial heart

Abiomed's US experts have succeeded in inventing Bi-VAD BVS 5000 - a new generation of polymer made with polymer with many outstanding features. The most important advantage of this type of artificial heart is that after implant surgery there is no need to connect any wires or pipes - a means that has always caused infection in patients with heart transplantation.

The Bi-VAD system operates fully automatically thanks to the battery and computer processor fully implanted in the abdomen, while the energy feeder is implanted in the right breast. The charging of the heart's energy can be carried out directly through the skin through electromagnetic radiation technology.

According to Professor Dominic Tedesso, author of the invention, he and his colleagues tested new hearts on 14 volunteer patients and the initial results were very good.
