Intestinal Phosphorus Absorption in Moderate CKD and Healthy Adults Determined Using a Radioisotopic Tracer

Journal of the American Society of Nephrology, 2021
Significance Statement Reducing intestinal phosphorus absorption through dietary restrictions and phosphate binders is common in managing and preventing CKD-MBD. Yet, how CKD pathophysiology affects intestinal phosphorus absorption is poorly understood.

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.

Dissolved and particulate phosphorus turnover in a river dominated marginal sea traced by cosmogenic 32P and 33P.

Water Research
Given the excessive nitrogen inputs and phosphorus (P) limitation in estuarine and coastal environments, P turnover rate is critical for regulating ecological dynamics.

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.

Efficient production and purification of 32P radioisotope from sulfur by dry distillation: A practical approach with high radiochemical purity.

Applied Radiation and Isotopes
The 32P radioisotope, with a half-life of 14.3 days and an energy level of 1.71 MeV, has diverse applications in medicine and research. Consequently, producing a carrier-free 32P radioisotope characterized by high radiochemical and radionuclide purity is
