Investigation of the Role of Organic Acids on the Phosphorus and Zinc Uptake by Corn in Calcareous Soils by Using 32P and 65Zn Radioisotopes [PDF]
To investigate the effect of oxalic and citric organic acids on the uptake of Phosphorus and Zinc by corn (Zea mays L.), an experiment was conducted by the use of radioactive potassium phosphate and zinc sulfate fertilizers in microcosm and greenhouse ...

A biosynthetic method for the preparation of high specific activity 32P-labeled phospholipids
32P-Labeled phospholipids with specific activities up to 400 mCi/mmole as well as [32P]CDP-choline were prepared by cultivation of mouse fibroblasts or mouse Ehrlich ascites cells in the presence of [32P]orthophosphate.

Impact of PNKP mutations associated with microcephaly, seizures and developmental delay on enzyme activity and DNA strand break repair [PDF]
Microcephaly with early-onset, intractable seizures and developmental delay (MCSZ) is a hereditary disease caused by mutations in polynucleotide kinase/phosphatase (PNKP), a DNA strand break repair protein with DNA 5'-kinase and DNA 3'-phosphatase ...

CINÉTICA DO FÓSFORO EM TECIDOS DE CORDEIROS RECEBENDO DIETAS COM CONCENTRAÇÕES CRESCENTES DO MINERAL
Avaliou-se o efeito do incremento na ingestão de fósforo sobre a cinética do mineral nos tecidos de cordeiros. Vinte e quatro cordeiros machos da raça Santa Inês com peso vivo médio de 34,5kg foram distribuídos em quatro tratamentos (0,16; 0,37; 0,58 e 0,

Level structure of 32P from 31P(d, p)32P reactions [PDF]
Abstract States up to an excitation energy of 6.8 MeV of the nucleus 32 P are investigated by studying the angular distribution of protons in the reaction 31 P(d, p) 32 P. One new state is found at 1.51 MeV. A state previously reported at 6.56 MeV is found to be a doublet with excitation energies 6.58 MeV and 6.53 MeV. The angular distributions for

Phosphorus utilization by corn as affected by green manure, nitrogen and phosphorus fertilizers
The objective of this work was to evaluate the utilization by corn plants of P from triple superphosphate fertilizer labeled with 32P (32P‑TSP), and of P from soil as affected by N rates and by the green manures (GM) sunn hemp (Crotalaria juncea) and ...

Phosphoproteins and protein-kinase activity in isolated envelopes of pea (Pisum sativum L.) chloroplasts [PDF]
A protein kinase was found in envelope membranes of purified pea (Pisum sativum L.) chloroplasts. Separation of the two envelope membranes showed that most of the enzyme activity was localized in the outer envelope.
