Embryotoxicity of Stable Isotopes and Use of Stable Isotopes in Studies of Teratogenetic Mechanisms
The Journal of Clinical Pharmacology, 1986Experiments on teratogenic effects of stable isotopes from our own and other laboratories are evaluated. In the first series of investigations, the enrichment of the stable isotope 13C derived from U‐13C‐glucose was studied in mouse embryos at various stages of development, including limb buds in organ culture.

Stable isotopes and a changing world
Oecologia, 2023The measurement of naturally occurring stable isotope ratios of the light elements (C, N, H, O, S) in animal tissues and associated organic and inorganic fractions of associated environments holds immense potential as a means of addressing effects of global change on animals.

Stable Isotopes: Origins and Safety
The Journal of Clinical Pharmacology, 1986Fundamental studies of the atomic elements in the first quarter of the 20th century resulted in the recognition of the isotopes of oxygen, carbon, nitrogen, and finally hydrogen. The unique character of a hydrogen isotope led quickly to its enrichment, to the investigation of its biologic effects, and ultimately to its use as a tracer in biologic ...

European Journal of Pediatrics, 1997
The increased employment of stable isotope tracers for diagnostic and research purposes frequently raises questions on potential risks associated with their use, which is of particular importance in the paediatric age group. Biological effects and the potential of adverse events has been evaluated in a large number of animal and, in part, also human ...

Stable isotopes in ecological studies
Oecologia, 2005Stable isotope ratio analyses at natural abundance levels are an increasingly useful tool in ecological studies, with new papers being published in nearly every issue of Oecologia and other ecological journals. In April 2004, the National Institute of Water and Atmospheric Research (NIWA) and the Institute of Geological and Nuclear Sciences (IGNS) co ...

Stable Isotope Probing and Plants
2014This chapter summarizes the applications of stable isotope probing (SIP) technology in plant-soil systems and presents an overview of the progress achieved in the understanding of the plant-soil microbe interactions and their role in ecosystem functioning.

Stable Isotopic Labeling for Proteomics
2011Since the coining of the term Proteome, the field of Proteomics has developed rapidly and come to rely heavily on mass spectrometry, initially for protein identification but recently the use of stable isotopic labels for protein quantitation has grown in importance.

Labeling Monosaccharides With Stable Isotopes
2015Chemical and chemi-enzymic methods are discussed for the preparation of monosaccharide isotopomers that are singly and multiply labeled with (13)C, (2)H, (17/18)O, and (15)N isotopes. The discussion focuses primarily on chemical methods to incorporate stable isotopes into monosaccharides and not on methods to assemble labeled monosaccharides into more ...

Nutrition, 1998
There is a need for non-invasive tests of gastrointestinal and nutritional function. Clinical problems peculiar to infancy and childhood require prompt diagnosis, and methods that are invasive or involve the use of radioisotopes are often impractical or ethically unacceptable. What the pediatrician and clinical scientist seek are tests that are simple,
