the prion MOVE along axons in the brain.

prion protein is found in the cell membrane of brain neurons. The misfolded form of the protein or infectious disease (also called "scrapie"), is responsible for the disease of so-called "mad cow

" and is involved in Creutzfeldt-Jakob disease in humans . Non-infectious and infectious forms of prion proteins interact causing the disease, so in order to help to find out how the infection spreads within and between nerve cells in the brain, scientists have studied the mechanism dell'USCD allows normal PrPC to move in neuronal cells of mice.

"Our job is to unravel the mechanism of this movement pemette the normal prion protein, and this will help us more fully understand their mechanism of action. Curiously, our work may also shed light on what happens in other neurodegenerative diseases like Alzheimer's

, "said Larry Goldstein, PhD, a professor at the Howard Hughes Medical Institute.

E 'known that the normal prion proteins and prions, "infectious" must interact so that the structure with abnormal prions alter normal, but do not know how it happen and why it happens.

prion protein load travels along microtubules, which are used as the actual tracks and this allows prion particles to move within vesicles along the peripheral nerves and central nervous system to the synapse. The intracellular transport is often bi-directional, because the loads on a regular reverse their route to final destinations. Researchers have identified what are the motors driving these vesicles that allow the movement forward (anterograde) of kinesin-1 moves only to the synapses and dynein, which is retrograde, moving away from the synapse. These two proteins "engine" are associated with the vesicles containing PrPC allowing them to move back and forth along the microtubules.

Secondly, it was discovered that the movement back and forth of these "loaded" is modulated by regulatory factors rather than by other structural changes of the association between motor and load. The study data show that the activity of kinesin-1 and dynein are tightly coupled, allowing the vesicles containing PrPC to move at different speeds and for various lengths along axons.

The study of the mechanisms that allow the movement of these vesicles along axons in the mouse cells could also shed light on other neurodegenerative diseases. While Alzheimer's is not generally considered an infectious disease like mad cow disease, emerging data suggest that Tau, beta-amyloid and alpha-synuclein - proteins involved in Alzheimer's disease and Parkinson's - have fibrillar structures can self-propagating with characteristics similar to those of prions. Understanding how the mechanisms occurring in movement of prion proteins may lead to the formulation of a therapy that can control the movement of intracellular aggregates and perhaps many other therapies for neurodegenerative disorders.

I think I've finally found the serenity . I have never been balanced, stable and sure of myself, because I was always lead to question everything, even the aspects of my life that an observer would judge perfect. I accepted the mistakes of others with a deep indulgence, but also in front of my smallest hesitation was very severe. I've always said "You can do more, you can learn more, you can improve more." I did not care that I deem more prepared and capable, I had to live up to myself, I had to constantly confront the claims-sometimes absurd-my pride, and not just in schools but in every field. Since the end of the summer but I was able to at least some moderate 'this aspect of my character, finding a quiet I never thought of being able to make my own. It was short and on time, I had to readjust to fight constantly against the expectations and goals that force myself to achieve. The last month has been difficult : every morning I woke up with doubt, uncertain themselves into a proper behavior and whether the choices I made would make me happy. I was not happy, I was again a prisoner of worst part of myself, the destructive, critical and inaccontentabile. Now I think to be able to appease all. I feel at peace with the world and with myself. I also decided I'm going to do philosophy (♥), the only matter that I love with all of myself. How many times that I came from one of my periods blacks I feel renewed and calm. Eventually I passed too!

February 9, 1849 after violent clashes


o'clock in the morning of 9 February 1849, a Constituent Assembly elected by universal suffrage in Rome approved a decree of four articles: Article 1
. The Papacy has been deprived of fact and law from the time of the Roman government.
Article 2. The Roman Pontiff will have all the guarantees necessary for independence in the exercise of his spiritual power.
Article 3. The form of the Roman state government will take the pure democracy and the glorious name of the Roman Republic.
Article 4. The Roman Republic will have relations with the rest of Italy, which requires a national policy.
Thus began the glorious story of the Roman Republic in 1849.
born following a liberal and democratic uprising in the territories of the Papal States, in the context of the great upheavals that shook the whole of Europe in 1848, attacked by the Bourbons and heroically defended by its citizens and many young volunteers came from all over ' Italy, July 4 fell only upon the powerful intervention of the French army sent by the government of Louis Napoleon supported the royalist-clerical.
The Constitution of the Republic, approved in the last days of life, draw, since its fundamental principles, a draft was extraordinary and ever present and remains its great testament ideal

FUNDAMENTAL PRINCIPLES I. The right to sovereignty is eternal in people. The people of the Roman State is in a democratic republic.
II.Il democratic government has to regulate the equality, liberty, fraternity. Does not recognize titles of nobility, or privileges of birth or caste.
III.La Republic with the laws and institutions to promote the improvement of hill moral and material conditions of all citizens.
IV.La Republic regards all people as brothers, respects all nationalities: the Italian advocates.
VI Hall all have equal rights: their independence is not limited by the laws of the State utility.
VI.La more equitable distribution as possible of local interests in keeping the State's policy is coll'interesse the norm of territorial division of the Republic.
VII.Dalla religious belief does not depend on the exercise of civil and political rights.
VIII.Il Head of the Catholic Church in the Republic will have all the guarantees necessary for the independent exercise of spiritual power.

five months of extraordinary passion, civil and democratic power of moral, political penalty during which Rome went from being a state among the laggards of Europe to test new democratic ideas, basing its political and civil life on values, such as universal suffrage, the abolition of the death penalty, freedom of religion and belief, the secular state, which in Europe were to become reality only about a century later
