Vogt–Koyanagi–Harada disease at the University of Tokyo, in 1911. It was the much later article, published in 1929, that definitively associated Koyanagi with the disease. Harada's 1926 paper is recognized for its comprehensive description of what is now known as Vogt–Koyanagi–Harada disease. Vogt–Koyanagi–Harada disease Vogt–Koyanagi–Harada disease (VKH), also known as Vogt–Koyanagi–Harada syndrome, uveomeningitis syndrome and uveomeningoencephalitic syndrome, is a multisystem disease of presumed autoimmune cause, that affects pigmented tissues, which have melanin. The most significant manifestation is bilateral, diffuse uveitis, which affects the eye. VKH may variably also involve the inner ear with effects on hearing, the skin, and the meninges of
Jens Ritter Instruments made of heavy brass and completely lockable with a design meant to produce perfect conduction of the string oscillation. Ritter B1 String Attachment Each string attaches to the body separately which is meant to produce an absolutely independent tone development with sonic transparency. The optional Ritter BB1 Tremolo System operates with 4 radial miniature ball-bearings. This construction is meant to produce smooth action without the friction commonly found in classic tremolo systems. With a gear-driven spring tension adjuster, the BB1 can allow regulation of the spring tension without removing the instrument's rear cover plate. In addition to the numerous shapes
