In a recent issue of the Journal, Taylor et al. (1) argued that selenium appears to play an important role not only in preventing various cancers but also in some degenerative diseases. Most of the data on the cancer prevention and cancer reduction effects of selenium are derived from epidemiologic studies (2). However, despite strong evidence for the importance of selenium in carcinogenesis, v...

The results of this examination show that the determination of Ca and inorganic P concentrations in the blood plasma and urine is of no significance for an early diagnosis of metabolic diseases of cattle skeleton, i. e. in the latent or prodromal stages of the disease. Data obtained by chemical analysis of the tuber coxae biopsy samples taken from cows with various forms of osteopathies due to ...

Magnesium (Mg) supplementation may be required when certain health problems or conditions such as Crohn’s disease or pregnancy cause Mg deficiency for which increasing dietary intake is insufficient. Mg supplements are available as inorganic or organic forms, which are absorbed differently. Although inorganic salts are particularly rich in elemental Mg, organic forms are generally considered to...

Phosphorus (P) regeneration and transformation in the oceanic water column and in marine sediments depends on the chemical nature of the sinking particulate P pool. For the first time, we have characterized the molecular composition of this pool, in various oceanic settings and water depths, using P nuclear magnetic resonance (NMR) spectroscopy. Both inorganic P (orthophosphate, pyrophosphate, ...
