Pituitary hormoneIn 1937, the successful isolation of the first of the protein pituitary hormones was published in Science journal. Bovine prolactin (bPRL), the lactogenic hormone, was obtained in pure crystalline form by three doctors at the Yale University School of Medicine. This meticulous, time-consuming work by A. White, H.R. Catchpole and C.N.H. Long was done long before the availability of modern chromatographic methods of analysis and purification. The peanut-sized pituitary gland at the base of the brain is the master endocrine gland in vertebrate animals. Different pituitary hormones control the functioning of most of the body's endocrine glands, stimulate growth and control the water balance of the body. Prolactin was first named for its ability to promote milk production in response to the suckling stimulus of hungry young mammals.«[Ref: White, A., Catchpole, H.R. and Long, C.N.H., 'A crystalline protein with high lactogenic activity', Science (23 Jul 1937), 86, 82-83.]
The Sailor And The Pirate
A sailor meets a pirate in a bar, and take turns boasting of their adventures on the high seas. The sailor notes that the pirate has a peg-leg, hook, and an eyepatch.
The sailor asks "So, how did you end up with the peg-leg?"
The pirate replies "We were in a storm at sea, and I was swept overboard into a school of sharks. Just as my men were pulling me out a shark bit my leg off."
"Wow!" said the sailor. "What about your hook"?
"Well...", replied the pirate, "While my men and I were plundering in the middle east, I was caught stealing from a merchant and the punishment for theft in the middle east is the loss of the hand that steals"
"Incredible!" remarked the sailor. "How did you get the eyepatch"?
"A sea gull dropping fell into my eye.", replied the pirate.
"You lost your eye to a sea gull dropping?" the sailor asked incredulously.
"Well...", said the pirate, "..it was my first day with the hook."
