De Quervain's tenosynovitis is inflammation of tendons on the side of the wrist at the base of the thumb. These tendons include the extensor pollicis brevis and the abductor pollicis longus tendons, which extend the joints of the thumb. De Quervain's tenosynovitis can be brought on by simple strain injury to the extensor pollicis longus and abductor pollicis tendons. Typical causes include stresses such as lifting young children into car seats, lifting heavy grocery bags by the loops, and lifting gardening pots up and into place.
double helix. n. The coiled structure of double-stranded DNA in which strands linked by hydrogen bonds form a spiral configuration, with the two strands oriented in opposite directions.
In 1962, Watson shared the Nobel Prize for Physiology or Medicine with Francis Crick and Maurice Wilkins who, with Rosalind Franklin, provided the data on which the structure was based. Watson wrote The Double Helix: A Personal Account of the Discovery of the Structure of DNA, which was published in 1968. This book was the first of its kind, being a gossipy account of the inner workings of the scientific world, and has never been out of print.
