Phosphorus acquisition by wheat from organic and inorganic sources labelled with 32P and 33P radioisotopes [PDF]
Scientia Agricola, 2020 : Investment in soil phosphorus (P) capital in the tropics is often constrained by poor availability of mineral fertiliser to small-scale farmers. Consequently, new sustainable agricultural cropping strategies are required to maintain fertility and ...

Phosphorus-32 in the Phage Group: radioisotopes as historical tracers of molecular biology [PDF]
Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2009 The recent historiography of molecular biology features key technologies, instruments and materials, which offer a different view of the field and its turning points than preceding intellectual and institutional histories. Radioisotopes, in this vein, became essential tools in postwar life science research, including molecular biology, and are here ...

Characterisation of soil phosphorus forms in the soil-plant system using radioisotopic tracer method [PDF]
Plant, Soil and Environment, 2021 Soil incubation and pot experiments were conducted to follow the sorption processes of added phosphorus (P) fertiliser using the radioisotope tracer technique. Increasing doses of P fertiliser (40, 80, 160, 320 mg P/kg soil) were added to Chernozem and Arenosol and incubated for 1, 3, and 13 weeks. After incubation, perennial ryegrass (Lolium perenne L.

Soil solution phosphorus turnover: derivation, interpretation, and insights from a global compilation of isotope exchange kinetic studies [PDF]
Biogeosciences, 2018 The exchange rate of inorganic phosphorus (P) between the soil solution and solid phase, also known as soil solution P turnover, is essential for describing the kinetics of bioavailable P.

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.

Hydroxyapatite (Ha) labeling with a phosphorus-32 radioisotope of the TRIGA 2000 reactor irradiation result as a candidate for radiosinovectomy therapy [PDF]
Journal of Physics: Conference Series, 2020 Abstract Radiosynovectomy is a therapy performed on patients with acute-level arthritis (rheumatoid arthritis) as an alternative solution besides surgery. Radiosynovectomy is performed using a labeled compound with a particle size of 0.5-10 μm labeled with a β radioisotope.
