Question: Passage: In August 2012, he made his European debut for the club, coming on as a substitute in a UEFA Europa League qualifying match against Gomel, replacing Joe Cole in a 0–1 away win. The following week, Sterling scored his first goal for the senior team with a first-half strike in a friendly against Bayer Leverkusen. On 23 August 2012, he started his first match for Liverpool in a Europa League qualifying match away to Hearts in a 0–1 win. He was given his first start in the league three days later in a 2–2 draw at Anfield to Manchester City. He played the full 90 minutes in the loss to Arsenal on 2 September, and the draw with Sunderland on 15 September, where he registered one assist and was named man of the match. On 19 September, Sterling was one of the group of teenagers that travelled to Switzerland to play Young Boys in a UEFA Europa League group match. He replaced Stewart Downing in the second half as Liverpool won 3–5. On 20 October, Sterling scored his first senior competitive goal for Liverpool in the 29th minute in a 1–0 league win against Reading with a strike from the edge of the box.

Question: Passage: Maryanoff has been active in the fields of medicinal chemistry and organic chemistry. He is an inventor of topiramate, a unique sugar sulfamate drug, which has been marketed worldwide for the treatment of epilepsy and migraine, attaining annual sales of more than $2 billion. Topiramate is also a principal component of the antiobesity drug Qsymia. Maryanoff is an internationally renowned expert in drug design and drug discovery, especially in the application of protein structure-based drug design. He made seminal contributions to understanding the stereochemistry and mechanism of the Wittig reaction; adapted the cobalt-catalyzed alkyne trimerization to the synthesis of macrocycles; and devised novel peptides that undergo self-assembly to mimic native collagen structurally and functionally. Maryanoff is an author on 280 scientific publications, including several books (editor), book chapters, and review articles. He is an inventor on 100 issued U.S. patents, has presented over 185 invited lectures worldwide, and mentored 11 postdoctoral associates. Maryanoff organized and edited a special memorial issue of the Journal of Medicinal Chemistry to honor the memory of Dr. Paul Janssen (2005) and has served on numerous editorial advisory boards for scientific journals and research grant review committees.
 Link Information: Topiramate was discovered in 1979 by Bruce E. Maryanoff and Joseph F. Gardocki during their research work at McNeil Pharmaceuticals. Question: How many years ago was the unique sugar sulfamate drug invented by Maryanoff approved for medical use in the U.S.?
