Heavy metals, such as, cadmium, zinc, Strontium and Arsenic have different chemical and physical properties. Also, each metal has its specific toxicological effects; in general, the contamination caused by heavy metals can have different effects in a human health. It is worth to summarize the effect of each element on human health. Scientific literature shows that cadmium affects the cardiovasc...

We present the synthesis of M-type strontium hexaferrite by sonochemistry and annealing. The effects of the sonication time and thermal energy on the crystal structure and magnetic properties of the obtained powders are presented. Strontium hexagonal ferrite (SrFe12O19) was successfully prepared by the ultrasonic cavitation (sonochemistry) of a complexed polyol solution of metallic acetates and...

BACKGROUND There is evidence from animal studies that lactose has a beneficial effect on intestinal calcium absorption. However, data concerning the effect of lactose on calcium absorption in lactose-tolerant adults are inconclusive. OBJECTIVE Our objective was to investigate the effect of lactose on calcium bioavailability in humans by the use of a stable-strontium test under controlled meta...

The title compounds, strontium perchlorate trihydrate {di-μ-aqua-aquadi-μ-perchlorato-strontium, [Sr(ClO4)2(H2O)3] n }, strontium perchlorate tetra-hydrate {di-μ-aqua-bis-(tri-aqua-diperchloratostrontium), [Sr2(ClO4)4(H2O)8]} and strontium perchlorate nona-hydrate {hepta-aqua-diperchloratostrontium dihydrate, [Sr(ClO4)2(H2O)7]·2H2O}, were crystallized at low temperatures according to the solid-...

BACKGROUND To avoid morbidity and limited availability associated with autografts, synthetic calcium phosphate (CaP) ceramics were extensively developed and used as bone filling materials. Controlling their induced-inflammatory response nevertheless remained a major concern. Strontium-containing CaP ceramics were recently demonstrated for impacting cytokines' secretion pattern of human primary ...

OBJECTIVES The nature of land use and mobility during the transition to agriculture has often been debated. Here, we use isotope analysis of tooth enamel from human populations buried in two different Neolithic burial monuments, Penywyrlod and Ty Isaf, in south-east Wales, to examine patterns of land use and to evaluate where individuals obtained their childhood diet. MATERIALS AND METHODS We...

This study investigated the effects of a new strontium-doped bioactive glass and fluoride on hydroxyapatite crystallization. We designed an in vitro experiment with calcium phosphate (CaCl2·2H2O + K2HPO4 buffer solution) different concentrations (1 mg/mL or 5 mg/mL), (0 ppm, 1 ppm ppm). Tris-buffered saline served as negative control. After incubation at 37 ? for 48 h, shape organization crysta...

BACKGROUND Surface functionalization of orthopedic implants with pharmaceutically active agents is a modern approach to enhance osseointegration in systemically altered bone. A local release of strontium, a verified bone building therapeutic agent, at the fracture site would diminish side effects, which could occur otherwise by oral administration. Strontium surface functionalization of special...

This report describes the case of a 57-year-old woman with liver and bone metastases from malignant insulinoma, who was afflicted with severe hypoglycemia. Treatment of the liver metastases using octreotide, diazoxide and transarterial embolization failed to raise her blood glucose level and she required constant glucose infusion (about 1000 kcal/day) and oral feeding (about 2200 kcal/day) to a...
