The Effects of Ethanol and Strontium on Growth and Development of Two-Cell Arrested Mouse Embryos

Sub-10 nm strontium titanate nanocubes highly dispersed in non-polar organic solvents.

Strontium titanate (SrTiO(3)) nanoparticles with well defined cubic shape and sub-10 nm size that are highly dispersible in non-polar organic solvents were successfully synthesized by hydrothermal (HT) processing. Water-soluble titanium complexes and strontium hydroxide were employed as precursors. When the HT process was carried out without oleic acid, the SrTiO(3) particles obtained were rela...

Strontium ranelate--a novel therapy for osteoporosis or a permutation of the same?

Osteoporosis was originally described in literature and art hundreds of years ago. Our ability to treat this disease lay dormant for centuries, but in the past 10 years, clinical trials have improved treatment options and efficacy. In this issue of the Journal , Meunier et al. 1 report on their study of the safety and effectiveness of strontium ranelate as a putative, novel therapy for osteopor...

Mechanism for the retardation of the acid dissolution rate of hydroxapatite by strontium.

Dissolution rates and apparent solubilities for synthetic hydroxyapatite in acetate buffers containing phosphate and strontium ions in the range of 10-3 to 10-2 M were determined under various pH and buffer conditions. Critical examination of the role of strontium with a physical model suggests that a calcium-strontium apatite surface complex may govern the driving force of the dissolution reac...

AIR POLLUTION: New Rules Proposed for Power Plant Toxics

Strontium-90 is a radioactive by-product of fission reactions within nuclear reactors that generate electricity. About 3% of the mass of spent nuclear fuel consists of fission products including strontium-90. Because of its high decay energy and its long half-life of 30 years—it takes hundreds of years to decay naturally to harmless levels—strontium-90 is classified a high-level waste. Strontiu...
