Ambito científico:
BIOETICA (BIOETHICAL)
Resumen:
A group of scientists have found a way of treat the diseases of the brain that is an almost unreachable place. The brain is a very difficult organ to study or explore, even to treat its diseases because of his protection against  any virus or drugs. So this treatment is based on the creation of a sort of a shuttle that pass his protection when the brain feeds of iron  in order to transport the necessary drugs to treat a disease.
The team who experiment this molecule has made some changes to protect it from being decomposed and making it more resistant. This experiment finally has been proved in animals such as rats and they had succeed.
VALORACIÓN CRÍTICA:
In my point of view this new experiment and discovery has been a great  advance in the neurology’s world.
By this way humans will be able to treat and even cure diseases from the brain  in a near future but before achieving this hopes the scientists and the experimenters of this project will have to experiment and try in human bodies that are not the same as rats.
This process is not short by far but with a big effort it could be possible one day and I think that the people  or the state should encourage this with economical aids in order to accelerate the experimentation process.
This intervention may be very expensive in the future because of its complexity and many people might not be able to afford it.
Trying this possible treatment will have disadvantages too, they could leave irreparable aftermaths.

GLOSARIO:
- IRB BARCELONA :  institute of biomedical research of Barcelona
- Blood brain barrier:  is a highly selective permeability barrier that separates the circulating blood from the brain extracellular fluid.
- Peptides: is formed by the union of a small number of amino acids

- Transferrin: is the specific carrier protein of iron in plasma.
