Stable Isotopes

2016
Abstract Stable isotopes provide traceability throughout the ocean. The isotopes of a given chemical element have the same electronic structure and the same chemical behavior but slightly different weights. Therefore, slight variations of their relative abundance occur in nature because the atom diffusion speed and the atom bond strength

Embryotoxicity of Stable Isotopes and Use of Stable Isotopes in Studies of Teratogenetic Mechanisms

The Journal of Clinical Pharmacology, 1986
Experiments 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, 2023
The 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, 1986
Fundamental 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 ...
