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
Regeneration in humans four weeks later. Research has also been conducted into the engineering of heart valves. Tissue-engineered heart valves derived from human cells have been created in vitro and transplanted into a non-human primate model. These showed a promising amount of cellular repopulation even after eight weeks, and succeeded in outperforming currently used artificial valves. Chronic obstructive pulmonary disease (COPD) is one of the most widespread health threats today. It affects 329 million people worldwide, which makes up nearly 5% of the global population. Having killed over 3 million people in 2012, COPD was the third greatest cause of death. Worse still
