Source of strontium in archaeological mobility studies—marine diet contribution to the isotopic composition

Archaeological and Anthropological Sciences, 2020
The strontium isotope composition of human tissues is widely used in archaeological mobility studies. However, little attention is paid to the relative contributions of terrestrial versus marine sources of strontium in these studies. There is some debate

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Multiple and Promising Applications of Strontium (Sr)-Containing Bioactive Glasses in Bone Tissue Engineering

Frontiers in Bioengineering and Biotechnology, 2019
Improving and accelerating bone repair still are partially unmet needs in bone regenerative therapies. In this regard, strontium (Sr)-containing bioactive glasses (BGs) are highly-promising materials to tackle this challenge.

Comparison between strontium administration and ibandronate injection effects on bone density of post-ovariectomy Wistar rat [PDF]

Гений oртопедии, 2020
Introduction Osteoporosis is a disease causing high morbidity with increasing prevalence. It is one of chronic diseases caused by reduced bone mass that subsequently decreases bone strength and increases fracture risks.

Metallicity and Superconductivity in Doped Strontium Titanate [PDF]

Annual Review of Condensed Matter Physics, 2018
Strontium titanate is a wide-gap semiconductor avoiding a ferroelectric instability thanks to quantum fluctuations. This proximity leads to strong screening of static Coulomb interaction and paves the way for the emergence of a very dilute metal with ...

Effects of strontium and boron interactions in Al-7Si alloys [PDF]

China Foundry, 2010
Effects of boron and strontium combined treatment on the microstructure of hypoeutectic Al-7Si alloy have been studied. Experimental results show that strontium has no significant effect on the grain refinement efficiency of boron and the eutectic ...

Strontium ion can significantly decrease enamel demineralization and prevent the enamel surface hardness loss in acidic environment

Journal of the Formosan Medical Association, 2019
Background/purpose: Strontium ion may play a role similar to calcium ion in enamel remineralization. The aim of this study was to investigate the effect of strontium ion concentration gradient on the demineralization of enamel.

Strontium potently inhibits mineralisation in bone-forming primary rat osteoblast cultures and reduces numbers of osteoclasts in mouse marrow cultures [PDF]

, 2014
The basic mechanisms by which strontium ranelate acts on bone are still unclear. We show that an important action of strontium salts is to block calcification in cultures of osteoblasts, the bone-forming cells.
