Eight major achievements in medicine since 2018



Two scientific teams They helped people with paralysis go back by stimulating the spinal cord with electrical impulses. Is it an injury in that area caused by an accident that prevents the brain's instructions from reaching the muscles, which prevents the individual from moving.

Thanks to electrical implants in the spinal cord, lost signals could reach their destination. And while these techniques are still experimental, one of the examined patients uses the device in their everyday life. While in another, there is evidence that the damaged nerves in the area began to regenerate.

The case that he voiced was that of Judy Perkins, who survived terminal cancer through pioneering therapy. There were tumors with a tennis ball size in the liver and secondary crabs around the body. Doctors gave him three months to live, while doctors at the National Cancer Institute in the US decided to try a new one "live drugs". Your tumor has been genetically analyzed to identify certain changes that might be visible to your immune system.

Of the 62 found genetic anomalies, only four offer potential lines of attack. And so did the search. The patient's immune system attacks the tumor, but white blood cells end up losing the fight against cancer. What the scientists did was to examine Perkins' white cells and to extract those who were able to attack their tumors. Then they increased in large quantities in the laboratory and injected them into their bodies (nearly 90,000m), along with removing drugs for the immune system. This new immunotherapy procedure led to Perkins cancer remission.

  • Transplantation of the womb of the deceased woman

For the first time in the world, A healthy baby is born from a dead woman's transplanted womb. Although there were previous attempts with this technique, they failed. While success was not achieved in Brazil, with a 32-year-old woman, that she was born without the womb due to the Meyer-Roitian-Couster-Hauser syndrome, which means that neither the vagina, nor uterus nor uterus form properly.

They are transplanting the womb of a deceased donor with brain bleeding, which had three children in life. Six weeks after the organ was built, the patient began to have his period.

Seven months later, fertilized eggs were implanted and, after a normal pregnancy, a girl was born with a caesarean section of approximately 2.5 kg.

  • First genetically modified babies

Chinese scientist has caused the greatest excitement in science in the years when claimed he had created the first genetically modified babies in the world. They are twins, who are obviously in good health.

Researcher He Jiankui claimed that he had changed the baby's DNA to protect them from HIV. However, details of the procedure have not been published, so their statements must be taken with skepticism. His announcement also provoked a profound ethical debate about whether the proceedings were to be conducted or not. Embryos were obtained by treatment with fertilization.

Experts have made significant progress in treatment the main cause of blindness in the world: age-related macular degeneration, also called maculopathy.

The macula is part of the eye that allows us to see what is in front of us, whether it recognizes faces, watching TV or reading a book. It is composed of cones and trails that experience light. Behind them there is a layer of nutrients, but when this layer fails, macular degeneration and blindness occur.

But one team discovered how to form a layer of supportive cells and implanted it as a patch over the injured layer. Patients who received this treatment regained the central sight not only for reading, but also to see people who were previously considered blurred.

Scientists from the University of Edinburgh, Scotland, developed a laboratory for mature human ovaries outside the ovaries for the first time. The technique can be used to develop new ways to preserve the fertility of girls who are undergoing cancer treatment.

It also presents an opportunity to investigate and ovules, whose development process still has many issues that science does not respond.

The procedure is an opportunity to explore ovules, whose development process still has many questions.

  • A blood test for cancer?

Scientists have progressed to the development of a universal blood test to detect cancer. This achievement was from a team at Johns Hopkins University, USA, who conducted a trial using a method that revealed eight common forms of the disease. This was possible because tumors release small traces of their mutated DNA and the proteins they form in the bloodstream.

The test CancerSeek requires mutations in 16 genes They usually occur with cancer and 8 proteins that are usually released from the disease. This test was tested for more than 1,000 patients with ovarian, liver, stomach, pancreatic, esophagus, colon, lung and breast tumors that did not spread to other tissues. The test was effective in 70% of cancer.

  • A germ, a hidden half of our body

It's not a matter of bad pressing of microbes. In fact, Mel Graves, a professor at the Cancer Research Institute in the UK, has collected 30 years of evidence showing that the immune system can become cancerous if it does not "see" enough microbes from the first stages of life.

The aim of this study is not to accuse parents of being overly clean, but to show what the price of progress in society and medicine is in things such as, for example, drinking water. The long-term goal is to give children a safe drink of bacteria – in yogurt – so that their immune system can train.
