Stable isotopes in clinical research: safety reaffirmed.
Approaching half a century of stable-isotope usage in human metabolic studies has been without documented significant adverse effect. Side-effects with acute D dosing are transitory with no demonstrated evidence of permanent deleterious action. The threshold of D toxicity has been defined in animals and is far in excess of concentrations conceivably used in human studies. The possibility that D...
متن کاملStable isotopes labeling of drugs in pediatric clinical pharmacology.
Stable isotope labeling (SIL) still has not been used very much in pediatric and perinatal clinical pharmacology. However, this method has numerous advantages. It allows one to determine the concentration of drugs with great sensitivity, thereby allowing quantification in small amounts of biologic samples. It also allows quantification with great specificity, eliminating interference by drug me...
متن کاملThe use of stable isotopes for diagnosis and clinical research.
Stable, non-radioactive isotopes, so long overshadowed by radionuclides, have recently become much more widely used in clinical science. This renewed interest has been stimulated by improvements both in the increased availability and diversity of stable-isotopelabelled compounds and in mass-spectrometric methods for their quantitative analysis. In addition, there is an increasing awareness of t...
متن کاملCurrent Practice GROWING POINTS Radioactive Isotopes in Clinical Medicine
There are four fundamental atomic particles-the proton, the neutron, the electron, and the positron. The proton has mass and a unit positive electrical charge. The neutron has mass and no charge. The electron has very small mass compared with the proton and neutron, and has unit negative electrical charge. The positron is the positively charged counterpart of the electron, having equal mass and...
متن کاملStable isotopes in tree rings
Stable isotopes in tree rings could provide palaeoclimate reconstructions with perfect annual resolution and statistically defined confidence limits. Recent advances make the approach viable for non-specialist laboratories. The relevant literature is, however, spread across several disciplines, with common problems approached in different ways. Here we provide the first overview of isotope dend...
