Phosphorus cycling and partitioning in an oligotrophic Everglades wetland ecosystem: a radioisotope tracing study

Freshwater Biology, 2003
Summary1. Our goal was to quantify short‐term phosphorus (P) partitioning and identify the ecosystem components important to P cycling in wetland ecosystems. To do this, we added P radiotracer to oligotrophic, P‐limited Everglades marshes. 32PO4 was added to the water column in six 1‐m2 enclosed mesocosms located in long‐hydroperiod marshes of Shark ...

Radioisotope Scanning for Tumors of the Head and Neck: Experience With Indium 111 and Phosphorus 32

Archives of Otolaryngology - Head and Neck Surgery, 1973
The use of four radioisotopes, selenium 75 (75Se), gallium 67 (67Ga), indium 111 (111In), and sodium phosphate 32 (32P), suitable for tumor scanning is discussed with emphasis on the diagnosis of malignant tumors of the head and neck. Personal experience with the latter two radioisotopes is described.

Cross-bridged cyclam derivatives with bis(phosphinate) and phosphinate-phosphonate pendant arms (cb-BPC) as chelators for copper radioisotopes.

Organic and biomolecular chemistry
Copper radioisotopes can be used for imaging as well as for therapy and, thus, can form ideal theranostic pairs. The Cu(II) complexes of cross-bridged cyclam (cb-cyclam) derivatives are considered to be highly stable in vivo.

Iron absorption in man: ascorbic acid and dose-dependent inhibition by phytate.

American Journal of Clinical Nutrition, 1989
The dose-dependent inhibitory effect of sodium phytate on iron absorption was studied in man by serving wheat rolls containing no phytates and rolls to which various amounts (seven dose levels between 2 and 250 mg expressed as phytate phosphorus) were ...
