Media activism on and off line by Italian adolescents and young adults

From several researchers it appears that Italian adolescents and young people are grown up with commercial television which is accused to contain too much violence, sex, reality shows, advertising, cartoons which are watched from 1 to 4 hours daily. Adolescents are also great users of mobile phones and spend a lot of time to use it. Their academic results are below the average of Ocse States. However the widespread use of communication technology and social networks display also another side of adolescents who engage in media activism and political movement such as Ammazzateci tutti!, Indymedia, Movimento 5 Stelle, Movimento No Tav. In which way does the world economic crisis -with the specific problems of Italy as the cutting founds for school, academic research and welfare, the corruption of political class, mafia and camorra organisation induce a reaction in our adolescents and young people? Several researches inform us about their use of internet in terms of spending time but, more important, how internet, and the web 2.0, could be an instrument for their reaction? What do they do online? How they do it? Which is the meaning of their presence online? And, has their online activity a continuity offline? The research aims are: 1. Trough a participant observation of Social Network profiles opened by 10 young active citizens, I would seek to understand which kind of social or political activities they engage in online as individuals and which is the meaning of their presence online. 2. To observe and understand if adolescents and young people have a continuity of their socio-political engagement online in offline activities and which kind of experiences it is. 3. Try to comprehend which was (or which were) the significant, learning experiences that convinced them about the potential of the web as tool for their activism.

Neurodegenerative diseases: molecular mechanisms and new strategies for neuroprotection

The term neurodegeneration defines numerous conditions that modify neuron’s normal functions in the human brain where is possible to observe a progressive and consistent neuronal loss. The mechanisms involved in neurodegenerative chronic and acute diseases evolution are not completely understood yet, however they share common characteristics such as misfolded proteins, oxidative stress, inflammation, excitotoxicity, and neuronal loss. Many studies have shown the frequency to develop neurodegenerative chronic diseases several years after an acute brain injury. In addition, many patients show, after a traumatic brain injury, motor and cognitive manifestations that are close to which are observed in neurodegenerative chronic patients. For this reason it is evident how is fundamental the concept of neuroprotection as a way to modulate the neurodegenerative processes evolution. Neuroinflammation, oxidative stress and the apoptotic process may be functional targets where operate to this end. Taking into account these considerations, the aim of the present study is to identify potential common pathogenetic pathways in neurodegenerative diseases using an integrated approach of preclinical studies. The goal is to delineate therapeutic strategies for the prevention of neuroinflammation, neurodegeneration and dysfunctions associated to Parkinson’s disease (PD) and cerebral ischemia. In the present study we used a murine model of PD treated with an isothiocyanate, 6-MSITC, able to quench ROS formation, restore the antioxidant GSH system, slow down the apoptotic neuronal death and counteract motor dysfunction induced by 6-OHDA. In the second study we utilized a transgenic mouse model knockout for CD36 receptor to investigate the inflammation involvement in a long term study of MCAo, which shows a better outcome after the damage induced. In conclusion, results in this study allow underlying the connection among these pathologies, and the importance of a neuroprotective strategy able to restore neurons activity where current drugs therapies have shown palliative but not healing abilities.
