Vitamin D has proven to be much more than a simple "calcium hormone." The fact that the vitamin D receptor has been found in cells not related to mineral metabolism supports that statement. The interest of nephrologists in vitamin D and its effects beyond mineral metabolism has increased over the last few years, evidencing the importance of this so-called "sunshine hormone." In the present revi...
The development of secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease. SHPT develops as a consequence of mineral metabolism disturbances and is characterized by elevated serum parathyroid hormone (PTH) and parathyroid hyperplasia. Evidence suggests that SHPT contributes to the development of vascular calcification and cardiovascular disease, as well as to th...
BACKGROUND AND OBJECTIVES The relationship between mineral metabolism disorders, bone fractures and vascular calcifications in kidney transplant recipients has not been established. METHOD We performed a cross-sectional study in 727 stable recipients from 28 Spanish transplant clinics. Mineral metabolism parameters, the semi-quantification of vertebral fractures and abdominal aortic calcifica...
Previous studies have suggested that kidney donors may have abnormalities of mineral and bone metabolism typically seen in chronic kidney disease. This may have important implications for the skeletal health of living kidney donors and for our understanding of the pathogenesis of long-term mineral and bone disorders in chronic kidney disease. In this prospective study, 182 of 203 kidney donors ...
The osteocyte has long been considered to be the primary mechanosensory cell in the bone. Recent evidence has emerged that the osteocyte is also a key regulator of various bone and mineral metabolism and that its regulatory effects are in part mediated through locally produced osteocyte-derived factors, such as sclerostin, receptor activator of nuclear factor-kappa B ligand (RANKL), and fibrobl...
INTRODUCTION It has been suggested that a dialysate calcium concentration of 1.5 mmol/L is a compromise between bone protection and cardiovascular risk. This study aimed to investigate the effect of reducing dialysate calcium concentration to 1.5 mmol/L on mineral metabolism and hemodynamic parameters. MATERIALS AND METHODS Dialysate calcium concentration was changed from 1.75 mmol/L to 1.5 m...
conclusions: in the current study, quality of life was correlated with serum calcium level, calcium-phosphate product, and serum pth level, while hospitalization was correlated only with serum phosphorus level. however, quality of life was inversely correlated with hospitalization. background: significant impairment in health-related quality of life (hrqol) among dialysis patients could be part...
To date, several bacterial species have been described as mineral-weathering agents which improve plant nutrition and growth. However, the possible relationships between mineral-weathering potential, taxonomic identity, and metabolic ability have not been investigated thus far. In this study, we characterized a collection of 61 bacterial strains isolated from Scleroderma citrinum mycorrhizae, t...
A metabolism study was conducted with rabbits to determine the effect of consumption of 5% dietary Senecio jacobaea (SJ) on tissue mineral levels and mineral excretion. Gastro-intestinal (GIT) absorption of pyrrolizidine alkaloids (PA) from SJ was also studied by monitoring excretion into urine and feces and by the use of ligated gut segments in vitro. Inclusion of SJ into a diet containing add...
als must be supplied in swine rations for optimum performance. About 5 percent of the total body weight of swine consists of mineral elements. These elements are essential for most of the basic metabolic reactions in the body. They have a role in digestion; metabolism of protein, fats, and carbohydrates; and the structure of chromosomes, enzymes, nerves, blood, skeleton, hair and milk. They are...
