Twenty-five years of progress in laboratory animal science

Twenty-five years of progress.

Twenty-five years of progress in bilirubin metabolism (1952-77).

This review deals with the development of our understanding of the chemistry of bilirubin and its glucuronide derivatives during the years 1952-1977. It examines the relation between haem metabolism and bilirubin formation and our present knowledge of hepatic transport of bilirubin. The heterogeneity of familial hyperbilirubinaemia is discussed.

Twenty-Five Years of Progress in the Three-Nucleon Problem

Twenty-five years ago the International Few-Body Conference was held in Quebec City. It became very clear at that meeting that the theoretical situation concerning the He and H ground states was confused. A lack of computational power prevented converged brute-force solutions of the Faddeev or Schrödinger equations, both for bound and continuum states of the three-nucleon systems. Pushed by exp...

Development of flexor tendon surgery: twenty-five years of progress.

Regaining satisfactory digital function after flexor tendon laceration and repair within the digit has long been one of the most difficult problems in hand surgery. Until the 1960s it was universally recommended that tendons divided in the digit (then referred to as “no man’s land”) should not be repaired. Bunnell taught that “it is better to remove the tendons entirely from the finger and graf...

Twenty-Five Years of Endocrine Disruption Science: Remembering Theo Colborn

The field of endocrine disruption is widely recognized as having formally begun in 1991 with the historic meeting at the Wingspread Conference Center in Racine, Wisconsin. This year, the National Institute of Environmental Health Sciences (NIEHS) celebrates the 25th anniversary of endocrine disruption science with an open meeting to explore past lessons and future directions (http://tools. nieh...
