Discoveries in medicine that have changed the world

Modern medicine failed to respond to the most terrible challenges of the past century( AIDS, cancer, adaptive bacteria, hybrid viruses), but it is constantly expanding its horizons, allowing humanity to hope for a panacea.

Today, increasingly, the search for drugs rests on DNA, which has coded prescriptions for all ailments. Soon you can expect the possibility of injections without needles, to implement Down's syndrome therapy during embryonic development. At the moment, scientists have managed to make unique discoveries.

Contraceptive for men

Employees of the Cancer Institute in Boston were able to create a drug that could revolutionize non-hormonal contraceptives for a strong half of humanity. The active substance of the new drug is JQ1, a substance capable of slowing the semen-specific protein of the bromodomain and blocking the formation of sperm. This remedy is completely devoid of sedative and anxiolytic effects. At the moment, it was possible to conduct a test on rodents, where the drug was able to show high efficiency.

Subsequently, a new drug will help prevent unwanted pregnancies in couples who avoid taking hormonal contraceptives.

Medication for bad memories

University specialists in Montreal were able to create a unique drug that can reduce people's access to unpleasant memories. This was a noticeable step towards correcting the work of memory. The drug was called metarapon. It is used in medicine for a long time, but before that it was prescribed for the diagnosis of "adrenocortical insufficiency".However, scientists were interested in the ability of the drug to lower the level of cortisol in the bloodstream. As a result, the person is weakened by the morbidity of memories and creates a positive outlook on what is happening.

A tool against racism

Scientists have been able to establish that the use of propranolol, which is widely used for ischemic disease, hypertension, helps to reduce the level of subconscious racism. The fact that the drug has a side effect in the form of a decrease in the activity of neurons, which are responsible for the severity of subconscious fears.

Conducting chromosomal therapy

Specialists at the University of Massachusetts have learned to turn off the creation of an extra copy of the 21st chromosome responsible for the development of Down syndrome. At the moment, it was possible to conduct in vitro experiments, but they will allow in the future to conduct therapy of this pathology during embryonic development and after birth.

During the research, scientists used stem cultures that could be isolated from the tissues of a patient with Down's syndrome. As a result, an "excess gene" could be inserted into the extra chromosome. The regulator of this gene was doxycycline, which is a broad-spectrum antibiotic. The effect of the "switch gene" could inactivate the activity of the extra chromosome, resulting in the cell becoming healthy.
