Rug Discovery .. (Translation Of Science Into Medicines)

Hello ..
this assignment is final portfolio .. we had to write four units in this portfolio during the semester .. at the end (now) we need to finish this by writing introduction and conclusion for the whole thing .. so if you can help me writing Introduction and conclusion for the four units Ill be thankful .. I put all the instructions they gave us in the first page and I also put the four units, in case you want to see them .. I think one page for intro and one page for conclusion should be enough .. if you think you need more than one page please let me know and Ill pay for extra pages.. can you please put citation within the text.

Many thanks
