ISOTOPIC RESPONSE

International Journal of Dermatology, 1995
Abstract Background. The occurrence of a new skin disorder exactly at the site of another one, already healed and unrelated, was first described in 1955. In 1985, Wolf et al. recognized that we are dealing with a dermatologic phenomenon and established a precise definition for this phenomenon.

Isotopic Distributions

2013
Isotopic information determined by mass spectrometry can be used in a wide variety of applications. Broadly speaking these could be classified as "passive" applications, meaning that they use naturally occurring isotopic information, and "active" applications, meaning that the isotopic distributions are manipulated in some way.

Isotope imaging

Baillière's Clinical Rheumatology, 1996
Patients with a wide variety of rheumatological conditions can be usefully investigated by nuclear medicine techniques and particularly by bone scintigraphy. This aspect of nuclear medicine work is increasing and the trend can be expected to continue.
