Barber shop

President George Bush and President Barack Obama ended up at the barbershop at the same time.

As they sat there, each being worked on by a different barber, not a word was spoken.

The barbers were even afraid to start a conversation, for fear it would turn to politics.

As the barbers finished their shaves, the one who had President Bush in his chair reached for the aftershave. President Bush was quick to stop him, saying: “No thanks, my wife will smell that and think I've been in a whorehouse.”

The second barber turned to President Obama and said: “How about you, Mr. President?

Obama replied, “Go ahead, my wife doesn't know what the inside of a whorehouse smells like.”

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.
