         97 . The method of  claim 94 , wherein the composition is administered to the individual intravenously, orally, and/or upon a device. 
     
     
         98 . The method of  claim 94 , wherein the composition is administered multiple times to the individual. 
     
     
         99 . The method of  claim 94 , wherein the composition is administered once a day, twice a day, once a week, twice a week, once a month, or twice a month.
