...activity. Earlier researchers suspected that the missing enzyme was hexosaminidase. Yet substantial amounts of hexosaminidase are found in Tay-Sachs victims. Neuroscientists John O'Brien and Shintaro Okada investigated hexosaminidase more intensively and discovered that it actually consisted of two enzymes, Hex-A and Hex-B. Both are present in normal tissue but, they found, only Hex-B occurs in the tissue of Tay-Sachs victims. So, they concluded, it is the absence of Hex-A that prevents the metabolism of fats in brain cells, and this results in the fatal disease...

The result was an artistic revelation...

Its kremlin (citadel), houses and surrounding fortress-monasteries have been restored to look just as they did in the 17th century. The beautiful 18th century Church of the Transfiguration was moved to its present site from another village. Over the next two or three years, the Soviet government plans to turn the Suzdal area into a new national tourist center, and will build an open-air museum and three new restaurants, as well as restore many other churches, peasant cottages and windmills...
