The different combinations of phosphorus to be found in a given tissue may be divided into three main groups: I. Protein phosphorus or phosphorus in combination with protein, including nucleoprotein and phospho-proteins or nucleoalbumins, insoluble in water especially after treatment with alcohol; 2. Lecithin and kephalin phosphorus or phosphorus in combination with fat and a nitrogen complex, ...

A comparative study on the cyanobacterial isolates, Anabaena ambigua Rao (A100) and Oscillatoria foreaui Fremy (A1340) were carried out to investigate the response of an organophosphorus insecticide Divap 100 at different concentrations of 1, 5 and 10ppm on the growth and release of extracellular products such as protein, nitrogen, ammonia, carbohydrates, amino acids and phenols. The experiment...

BACKGROUND Elevated serum phosphorus might aggravate the effect of hypertension on mortality. The objective of this study was to examine the joint effect of hypertension and serum phosphorus on the risk of mortality. METHODS AND RESULTS A large prospective (n=15 833), population-based cohort of participants from the National Health and Nutritional Examination Survey III was examined to test p...

Eosinophil degranulation has always aroused the interests of physicians and scientists alike. Loss of viability and release of membrane-free granules upon eosinophil degranulation was first demonstrated by Gleich and coworkers in 1996. These free eosinophil granules, once considered as crush artifacts, are now confirmed products of eosinophil cytolysis, and suggested to be significantly pathoge...

Carboxylates, such as malate and citrate, are widely acknowledged to have a central role in plant metabolism. They are involved in the production of energy and its storage as well as contributing to the cellular osmolyte pool and participating in the regulation of cellular pH. As we discuss here, recent research has demonstrated the functional importance of carboxylate excretion into the soil, ...

Engineering phosphorus heteroatoms into the plane of ultrathin MoS2 nanosheets is realized via a facile thermolytical process. The doping of low-electronegative P atoms generates an extra ORR activity with four-electron selectivity, manifesting seven-fold current increase as well as 160 mV positive shift in both onset and half-wave potentials.

The content of the phosphorus fractions in bacillus spores reveal a marked difference in the quantity of residue phosphorus (Fitz-James and Young, 1959). In particular, the spores of two strains of Bacillus megaterium contained a residue phosphorus of over 1 per cent of the dry weight whereas in another strain it was essentially nil. This residue fraction remaining after a modified Schmidt and ...
