In Memoriam : Robert Danis, an inspiration for Maurice Müller and origins of the AO Foundation.

Acta Orthop Belg 2020 Dec;86(4):577-579

Robert Danis (1880-1962) was a Belgian general surgeon mostly remembered for his contributions in the field of bone and joint surgery, a medical subdiscipline currently known as orthopaedic trauma surgery. He initiated this with his first book (1) on the subject in 1932. Danis was the first to develop a concept for biomechanically stable internal fracture fixation, creating and producing his own screws and plates with self-developed machine tools. Read More

Immunohistochemistry in surgical pathology: principles and practice.

Authors:
Clive R Taylor

Methods Mol Biol 2014 ;1180:81-109

Department of Pathology, HMR 311, Keck School of Medicine, University of Southern California, 2011 Zonal Avenue, 90033, Los Angeles, CA, USA,

The extent to which data from immunohistochemical (IHC) staining are useful is critically dependent not only upon the proper performance and control of the method but also upon appropriate interpretation. A decade ago an individual pathologist may have nurtured a reasonable expectation of achieving a comprehensive understanding of the IHC literature across the whole field of pathology. Today such an expectation is clearly unreasonable with a simple Medline search of the IHC literature postdating the general adoption of antigen retrieval (arbitrarily 1996), yielding more than 100,000 "relevant" articles.
