NOTICIA NUM.9
TITULAR: Los científicos españoles
defienden la experimentación con animales
Fecha de publicación: 19 FEB 2015
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.
