In this entry I will speak about a liposomes, this nanoparticules are the most I know because  with my colleagues we made a report and we made a presentation about them the last week.  Liposomes are a nanoparticules of natural origin and semi-sintetic, they are formed by a phospholipid layer which can contain any particle  water soluble inside, because this we can transport any drug  selectively, this is possible by modifications on the surface of the liposomes. You can add different proteins to fulfill this function! These can transport anticancer agents for the treatment of cancer, for example skin cancer. With the use of the liposomes could be used less doses since to be directed specifically to the cancer cells would not lose drug to other areas of the body, also this it allows reduce the secondary effects because the drugs are cytotoxic and with liposomes the drug can acts onlyy in the action site. This can help a to many people with differents tipes of can...

Hello, today I will tell you about one of my favorite subject,  Physiology. I really like this subject because it encompasses other subjects such as chemistry, biology and physics, and it is seen from the functions of the human body as well as being one of the first subjects that take concepts and are a kind of introduction to higher subjects of the career like farmacology I think and this is exciting . In classes I pay attention and try to write everything that the teacher says but I think the hours of classes are bad distributed, there are also seminars where we can solve doubts about the subject, the teacher explains very well and the helpers are very willing to resolve doubts, are very committed and whenever they see us they tell us about the notes, controls and give us encouragement.   Although the notes that I have had are not what I expected, I still try it although there is not much left for the end of the semester...Thanks for reading, I will be attentive ...

It was Marie Curie who was born on 7 November 1867 in Poland. Passionate for the exact sciences as physical and chemical emigrated to Paris since in her country women were not allowed to study in the university.  his first Nobel Prize was thanks to the research done on radioactivity with her husband. In addition, his second Nobel Prize was due to the discovery of radium and polonium, and she alone won it,! Unfortunately, she died in 1934 because its studies with radioactive elements produced a disease to him to the blood that caused the death I admire her because she was the first woman to be recognized for her achievements, despite the difficulties I face for the simple fact of being a woman. believe she is an example to follow because of her perseverance, effort and his contribution to science...
