5 'revolution' in medicine

Changing body parts such as changing wheels, surgery without opening, hearing heart rate by clothes, cancer treatment with micro-pills, expressive gene analysis . are revolutionary technologies in medical, according to the vote of Marianne Weekly (France).

Change human parts like . change wheels

Changing old damaged body parts with new parts is a dream for many generations of humans. In fact, medicine can be done by grafting organs (humans and neighboring animals) or by inserting an artificial organ.

However, it is impossible to match a completely new, genetically appropriate copy from the patient's own cell. This can become a reality when Genzyme Company in Cambridge (USA) succeeds in replacing damaged cartilage in the knee with completely new cartilage. This year, Pennsylvania's Tengion Company also intends to transplant blood vessels to "heart " cultivated cardiovascular patients in the laboratory from the patient's own cells. Thus, when lying in the body, graft blood vessels are no longer afraid of being eliminated.

Kill cancer cells with tiny tablets

This is the method proposed by the Massachusetts Institute of Technology (USA). Accordingly, one would use a tablet of 200 nanometers (1 billionth of a meter) into the tumor to kill cancer cells. The tablet consists of an outer layer that dissolves slowly so that when it enters the tumor it releases a substance that destroys blood vessels. Once cancer cells have no blood vessels, they are killed with a toxin from the secreted drug. The method is very safe and effective.

Surgery does not need to be opened

Now this technology is available under the name of "endoscopic surgery". In the future, it will go farther: Through the scaffold, people put the germ cells into their organs to create a new series of cells to replace damaged cells. In the short term, this method can be applied in cardiovascular through Da Vinci robot surgery method. Just drill 3 small pea holes on your chest, people will replace the heart valve without opening the chest.

Expression gene analysis

The current genetic analysis requires a lot of effort and time. This will be reversed by a DNA bug, which can analyze thousands of DNA fragments in extremely short time. Their applications are diverse: Detecting disease-carrying genes, identifying relatives .

The technology is completely grounded in, because in 2005, Affimetrix launched the FoodExpert-ID bug to help distinguish traces of 32 different animal meat types such as cows, chickens, and sheep. goats, fish .

Clothing 'hears' the heartbeat

Currently, some patients with arrhythmias must wear a vibrator or a pacemaker, which is quite bulky and requires trouble installing. In the near future, these people just need to wear a smart cotton shirt that can "hear" the heartbeat; When necessary, the shirt will automatically 'fix' any irregularities. This European project is named MyHeart (my heart).
