ALHZEIMER

Alzheimer it's a progressive disease that destroys the memory and other mental functions because of the deterioration and death of brain neurons. The symptom of this disease are: changes in the personality, changes in the mood, problems for pay attention and in the orientation, low levels in energy, among others. It's the most common form of dementia, it's incurable and terminal. The causes of Alzheimer's are unknown but the most of the time this occurs in elderly people.

I choose this disease because I knew a lot of friends who have family members who suffers this terrible illness and because I think we have to support more the people who are diseased and the family or the people who taking care of him or her.

In itself the Alzheimer it is equally common in all parts of the world but the 60% of the cases of Alzheimer they are in countries with low and middle income.

As Alzheimer's affects neurons, this in turn affects the muscular system and in some more severe cases the cardiorespiratory system.

International Alzheimer's Day is commemorated on September 21, the date was chosen by the WHO and the International Alzheimer's Federation, in which activities are carried out in various countries to raise awareness and help prevent the disease.

The most enjoyable subject

In this semester I really like so much the subject of chemical laboratory techniques, in this subject first we do a theory class about a type of the differents laboratory techniques that there are , for example: distillation, filtration, solutions, etc, then we do the practical part (for me is the best part of the class) when we put into practice what they taught us before. 

It's my favorite subject because, every week we do something different from the previous one and also is the kind of subject that has as much theory part as to practice part.

And also this subject it's so important in our future professional life because, when we will be graduates always will have contact with a laboratory, so it's very necessary that from our first year of university we begin to enter in the lab, his instruments, his rules and his precautions.

Marie Curie

One of the most expert on science that I admire is Marie Curie, she was the first person and woman who receiving two Nobel prizes for his works in radioactive energy and the discover of the elements radium and polonium.

She was born in 1867, in Varsovia, Poland and she died in 1934, in Passy, France cause the constant contact she had with radioactive compound. At a very short age she was interested by the biology and chemistry something unusual at the time. Because of the limited opportunities to study in Poland she traveled to Paris, there she study at the Sorbonne, Paris getting a degree in physics and math then she meet her future husband Pierre Curie who was a renowned chemist, they got married and worked together in the laboratory studying the radiation. 

Pierre and Marie Curie

She made great contributions to understand the radioactivity also she was the figure of many scientific women to have a space in the scientific community.

I admire her so much because she had to effort every day to be able to reach his goals and dreams just because she was a woman, but that never stopped her.
