         <description><![CDATA[<div>La vitamina A esiste in 3 forme: retinolo, retinale e acido retinoico. Questa vitamina è implicata nei processi molecolari che sono alla base del meccanismo della visione, attraverso la conversione dell'11-cis-retinale in trans-retinale. La molecola del retinale è costituita da un anello esagonale insaturo e da una catena idrocarburica contenente doppi legami. Tale molecola è un componente della rodopsina, contenuta nelle cellule della retina chiamate bastoncelli. Quando la luce visibile viene captata dalla rodopsina, il cis-retinale si trasforma nel suo isomero trans. La sua carenza pertanto provoca disturbi visivi.</div>]]></description>

         <description><![CDATA[<div>Gli amminoacidi sono composti che presentano allo stesso tempo un gruppo amminico e un gruppo carbossilico. Gli amminoacidi presenti in natura sono tutti α-amminoacidi, cioè molecole di acidi carbossilici nelle quali il gruppo amminico si trova in posizione α rispetto al carbossile. Tutti gli amminoacidi oltre al gruppo amminico e carbossilico, possiedono anche una parte variabile, il radicale R. Tranne nel caso della glicina, il cui gruppo R variabile è rappresentato da un atomo di idrogeno, in tutti gli altri amminoacidi il carbonio α risulta avere 4 sostituenti diversi e perciò costituisce uno stereocentro; di conseguenza, tutti gli amminoacidi potranno esistere in 2 forme speculari non sovrapponibili (enantiomeri). A causa di ciò si chiamano L-amminoacidi quelli che hanno il gruppo amminico sulla sinistra, mentre D-amminoacidi quelli che hanno il gruppo amminico sulla destra.</div>]]></description>

Chromatin immunoprecipitation and luciferase reporter assays were used to determine the interacting molecules and the activity of the enzyme. An in vivo study was carried out in GC xenograft mice.</div><div>RESULTS: PCI-24781 significantly reduced the growth of the GC cells, enhanced cell apoptosis and suppressed clonogenicity, and these effects synergized with the effects of CDDP. PCI-24781 modulated the cell cycle and significantly.</div>]]></description>

         <description><![CDATA[<div>The theme of the double The Strange Case of Dr Jekyll and Mr Hyde is Robert Louis Stevenson's most famous and important novel and it is one of the greatest classics of the fantasy genre. The theme of the double Henry Jekyll is a brilliant scientist who, by mixing special drugs, succeeds in creating a potion which is able to separate the two nature of man: good and evil. The latter, the deformed and repulsive Mr Hyde, slowly manages to prevail over the former and commits several wicked and criminal deeds. The theme of the double The novel represents the eternal struggle between good and evil, which, this time, live together in the same person: Jekyll and Hyde are the symbol of a double personality. The theme of the double Dr Jekyll and Mr Hyde are symbolic of the duplicity of the Victorian Age: on one side Jekyll represents the public face of the individual and is a respectable man; on the other side, at night in the bad areas of London, he is Mr Hyde, who represents the dark side present in all people. The theme of the double Even the name Hyde is linked to the theme of the double: it means to hide, to do what you cannot do openly. The theme of the double In Frankenstein by Mary Shelley, Victor Frankenstein, creates a monster that in a certain way represents his double. The theme of the double As a consequence of his manipulations with nature, Frankenstein is punished because his creature kills the people that the doctor loved. The theme of the double Wilde's The Picture of Dorian Gray is the story of a young man that is very beautiful: his portrait represents his double, his soul corrupted by his bad actions. At the end of the novel, Dorian dies when he destroys his picture with a knife. A common element in all these stories is their moral message: sooner or later the protagonists will be punished for their sins because in the end the evil will be defeated.<br><br></div>]]></description>

         <description><![CDATA[<div><em>Nel romanzo Uno, nessuno e centomila</em> Pirandello, attraverso la metafora della maschera, spiega come l’uomo si nasconda dietro una “maschera”, un velo di Maya che non consente di conoscere la propria personalità. Nella realtà quotidiana gli individui non si mostrano mai per quello che sono, ma assumono una maschera che li rende personaggi e non li rivela come persone. La maschera non è altro che una mistificazione pirandelliana, simbolo alienante, indice della spersonalizzazione e della frantumazione dell'io in identità molteplici, e una forma di adattamento in relazione al contesto e alla situazione sociale in cui si produce un determinato evento.</div>]]></description>
