From the invisible to the visible world and back...

Today I will speak about of a very interesting subject in the field of sciences especially in pharmacology...the Liposomes. 
The liposomes are nanoparticles, which are used as a vehicle for administration of nutrients and pharmaceutical drugs. 
I studied this issue for the subject "Research for the pharmaceutical sciences", where we specifically focus on the action of liposomes on skin cancer. 
This topic is very important in the pharmacological world because the liposome acts as a vehicle for anticancer agents , targeting cancer cells specifically without side effects as in common therapies (For example chemotherapy, which has cytotoxic agents that attack both good and bad cell, causing secondary affections such as hair loss).
One of the advantages of liposomes is that various modifications can be made to improve their specificity, such as adding proteins to the surface of their membrane, which will make a better recognition of the cancer cells, releasing the anticancer agent(drug) only in those "bad cells ". On the other hand, this treatment is so new and innovative, that even the scientists continue making various modifications to the liposomes, which are very expensive, which is a great disadvantage if you want to generate a cure in the skin cancer.
This topic we exposed with my friends a week ago, and clearly if the scientists continue with the studies of liposomes and their various modifications to treat not only skin cancer if not any other type, you could reach a cure, which Is a necessity nowadays in many people.

The most enjoyable subject ...

Hi people! Today I will speak about to my favorite subject Organic Chemistry.

Organic chemistry is a subject which combines the theoretical with the practical in equal parts since I have organic chemistry and organic chemistry lab; both subjects are a challenge, because it is the basis of everything that I can learn in the future.

 For me, the organic chemistry is very interesting because this subject studies all those compounds that contain carbon, and almost everything that one eats, drinks or simply what makes the body work is produced thanks to carbon (for this reason the carbon is called the basis of life ).

My classes of organic chemistry are divided into two parts, one of theoretical class, and another called seminary, where you practice what is seen in the theoretical class and everything that I learn in this subject, I apply it in organic chemistry lab, and that I just love it! Here we can synthesize so many things, and see so many reactions that it just makes me wonderful to go to the laboratory.

Well...learning organic chemistry will help me in the future to be able to synthesize drugs in order to help people, and that is the most important thing for me.

Person/Expert you admire

The greatest contributors to science have always been men and they have always been rewarded for their discoveries since ancient times, but women have also contributed a lot to science, for example, Maria Curie, Jane Goodall, Emmy Noether, or Barbara McClintock, she discovered the transposition – genes moving about within chromosomes – often described as jumping genes, and showed that genes are responsible for switching the physical traits of an organism on or off, but for a long time his works were not taken into account, 30 years later he was awarded the Nobel Prize...30 years!! is something I still can not believe!

But the most emblematic and admirable case for me is the Rosalind Franklin. She was born on July 25, 1920 in London, the second of five brothers, three of them men, in a Jewish family that had four generations dedicated to the banking. At age 18 she passed the entrance exam at Newnham College in Cambridge to study experimental sciences and, in particular, chemistry.  Her father did not accept Rosalind's decision and took away her support of money, however, but his aunt paid his studies, and so she graduated from the University of Cambridge in 1941. She learned crystallography and X-ray diffraction, techniques that she applied to DNA fibers. One of her photographs (Known as photograph 51) provided key insights into DNA structure. But, Other scientists (Watson and Crick) used it as evidence to support their DNA model and took credit for the discovery, who were awarded the Nobel Prize in Physiology and Medicine in 1962. 
Rosalind Franklin never received any recognition in life, on the contrary, Watson and Crick almost never mentioned it, but that was not an impediment to continue looking for the answer to questions that were unimaginable, teither was her father an impediment for her to study! For these and many other reasons as her discoveries is that she is a woman to admire ... we must always look for ways to produce knowledge regardless of the difficulties that are put in the way or the prizes that one can receive for it .
