Milwaukee shoulder syndrome: Milwaukee shoulder syndrome (apatite-associated destructive arthritis) is a rheumatological condition similar to calcium pyrophosphate dihydrate deposition disease (CPPD). It is associated with periarticular or intraarticular deposition of hydroxyapatite crystals.ChondrocalcinosisTetrasodium pyrophosphateHexagonal crystal system: In crystallography, the hexagonal crystal system is one of the 7 crystal systems, the hexagonal lattice system is one of the 7 lattice systems, and the hexagonal crystal family is one of the 6 crystal families. They are closely related and often confused with each other, but they are not the same.Water injection (oil production): Water injection or water flooding refers to the method in the oil industry where water is injected into the reservoir, usually to increase pressure and thereby stimulate production. Water injection wells can be found both on- and offshore, to increase oil recovery from an existing reservoir.Octacalcium phosphateTophusNucleotide Pyrophosphatase/Phosphodiesterase (NPP): Nucleotide pyrophosphatase/phosphodiesterase (NPP) is a class of dimeric enzymes that catalyze the hydrolysis of phosphate diester bonds. NPP belongs to the alkaline phosphatase (AP) superfamily of enzymes.ATC code M04: ==M04A Antigout preparations==Calcinosis cutisOsteoarthritis Research Society International: The Osteoarthritis Research Society International (OARSI) is a non-profit scientific organization.OARSI.Knee pain: Knee pain is a common complaint for many people. There are several factors that can cause knee pain.Thiamine pyrophosphateArticular cartilage repair: The aim of an articular cartilage repair treatment is to restore the surface of an articular joint's hyaline cartilage. Over the last decades, surgeons and researchers have been working hard to elaborate surgical cartilage repair interventions.Arthritis Research UKCalcium encodingUndecaprenyl phosphate N,N'-diacetylbacillosamine 1-phosphate transferase: Undecaprenyl phosphate N,N'-diacetylbacillosamine 1-phosphate transferase (, PglC) is an enzyme with system name UDP-N,N'-diacetylbacillosamine:tritrans,heptacis-undecaprenyl-phosphate N,N'-diacetylbacillosamine transferase. This enzyme catalyses the following chemical reaction
