The rats that received more raspberry ketones burned more body fat and gained less fat tissue. A third study exposed fat cells in a test tube to raspberry ketones and found that the raspberry ketones stimulated the breakdown of the fat cells.
Notre Dame Cathedral in Paris was built by decree of Bishop Maurice de Sully in 1163 A.D. Like almost all medieval cathedrals, it took many years (and several successive Bisho â¦ ps) before it was finished. The average start to finish time of a Cathedral in that era was about a century.
It also has the greatest interior volume of any French cathedral, estimated at 200,000 cubic metres (260,000 cu yd). The cathedral was built between 1220 and c.1270 and has been listed as a UNESCO World Heritage Site since 1981.
