A part in the play

A young lad's father picked him up from school to take him to a dental appointment.

Knowing the parts for the school play were supposed to be posted today, he asked his son if he got a part.

The boy enthusiastically announced that he'd gotten a part. "I play a man who's been married for twenty years."

"That's great, son. Keep up the good work and before you know it they'll be giving you a speaking part."

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.
