Long jump at the Olympics gold medals in its brief history. From 1900 to 1912 a variation of the event was contested at the Olympics where athletes had to long jump from a standing position. This was one of three standing jumps to have featured on the Olympic programme, alongside the standing high jump (present for the same period) and the standing triple jump (1900 and 1904 only). The standing jump competitions were dominated by Ray Ewry, who won the Olympic standing long jump titles in 1900, 1904 and 1908. His clearance of at the 1904 Olympics remained as the Olympic record for the event
Hop (protein) Hop (protein) Hop, occasionally written HOP, is an abbreviation for Hsp70-Hsp90 Organizing Protein. It functions as a co-chaperone which reversibly links together the protein chaperones Hsp70 and Hsp90. Hop belongs to the large group of co-chaperones, which regulate and assist the major chaperones (mainly heat shock proteins). It is one of the best studied co-chaperones of the Hsp70/Hsp90-complex. It was first discovered in yeast and homologues were identified in human, mouse, rat, insects, plants, parasites, and virus. The family of these proteins is referred to as STI1 (stress inducible protein) and can be divided into yeast, plant, and animal STI1
