Chinese Business Trip

A man went on a business trip to China and wanted to buy some gifts for his kids. He went to a shop and found a nice looking CD player. Wary of buying inferior goods, he asked the shopkeeper, 'What would happened if this does not work?'
The shopkeeper quietly points to the only sign in English that reads, 'GUARANTEE NO SPOILT'.
Feeling assured, he paid for the CD player and returns to his hotel. He tried to use the CD player after returning to the hotel but it would not even switch on.
He quickly return to the shop and asked for a refund or an exchange for another unit. When the shopkeeper refused to give either, the man points to the sign assuring him of a guarantee.
The shopkeeper then said, 'Brother, you are in China. We read from the right to the left.'

Thyroxine

In 1914, the thyroid hormone, thyroxine, was first crystallized by biochemist Edward C. Kendall of the Mayo Foundation in Rochester, NY. Thyroxine controls the cellular rate of carbohydrate metabolism and of protein synthesis and breakdown. On Dec 23, he began evaporating an ethanol solution of a sample of the acid-insoluble fraction of thyroid glands removed surgically from patients. It left a white crust surrounded by a ring of yellow waxy material. Adding ethanol now redissolved the waxy material, but not the white crust. On Christmas Day, he dissolved some of the white crust in ethanol and sodium hydroxide. A few drops of acetic acid precipitated crystals. This throxine was fully active in relieving the symptoms of thyroid deficiency in hypothyroid patients.
