![]() Pitolisant, the first in its class, has changed the way narcolepsy (with or without cataplexy) is managed and dramatically improved the quality of life for those suffering from the condition. This discovery led to the development and commercialisation of pitolisant (Wakix™) by Bioprojet in Europe and Harmony Biosciences in the USA. After many years without discovering a drug, he took a different, first principles approach to generate a type of chemical structure that led to Wakix™. Professor Ganellin’s research group synthesized novel chemical compounds that were tested in Paris. His research group in Paris identified histamine H3 receptors that controlled histamine transmission and demonstrated that histamine was a neurotransmitter that probably led to wakefulness. Upon joining UCL, Professor Ganellin started collaborating with French neuroscientist Professor Jean-Charles Schwartz. Professor Robin Ganellin (UCL Department of Chemistry) had been researching with biologists since 1964, when he worked in industry, focusing on histamine receptors. Prior to the commercial release of pitolisant, there was an unmet need for an effective, safe, and tolerable treatment regime in the management of narcolepsy. It significantly decreases the quality of life of the affected individuals, with two-thirds of patients being unable to work. Detachable 18ct brooch.Narcolepsy is a disabling, long-term neurological disease that affects 1 in 2,000 individuals (approximately 30,000 people in the UK and 165,000 people in the USA). The movement flared brightly but briefly and by 1910 it was already going out of style to be replaced by Art Deco. The “New Art” style became a worldwide movement encompassing all disciplines of the arts, and world class artists as far afield as Gaudi with his “modernisme” architecture in Spain, Louis Comfort Tiffany in New York with objects, Galle Glass in France and the Liberty & Co Archibald Knox designs in Britain, Jugendstil in Northern Europe and Faberge in Russia. However, during the Art Nouveau period, jewellers adopted the idea of using other semi–precious stones “from nature” such as agate, garnet opal, moonstone, aquamarine and experimented with a wide variety of new techniques e.g. Before the Art Nouveau period, the emphasis had been to design pieces with an emphasis on gem stones, diamonds, rubies emeralds etc. Artists, such as William Morris, took their inspiration from the flora and fauna of nature and rejected the mass industrialisation and mechanisation of the Victorian age.Īrt Nouveau continued with this theme and has a distinctive appearance with soft, curved shapes and lines and often depicted natural designs such as flowers, birds and the female form. It had its roots in the Pre Raphaelite and Arts and Crafts movements in Britain in the 1860’s. The Art Nouveau period was a short lived but worldwide movement which reached its peak at the end of the 19th Century and the first decade of the 20th Century. A very thin layer of silver was applied to the gold, on which the diamonds were set, to show them off to their best advantage (as the yellow would reflect and distort the white colour of the diamonds). Setting diamonds in gold with a thin layer of silver, “silver set”, was a technique used in the Georgian/Victorian/Art Nouveau period as white coloured gold and platinum were not yet available.
