“…Strontium (Sr) is an alkaline element and rare earth metal (Browning & Cowieson, 2013 ). The physical and chemical properties are similar to that of calcium (Skoryna, 1981 ). In addition, stable Sr isotopes do not have any significant health threat (Gulson & Wong, 2006 ).…”

Background: In the modern broiler industry, leg and gait disorders are considerable problems. Fast-growing broilers are especially susceptible to bone abnormalities, causing major problems for broiler producers. Strontium ranelate (SrR) has been used successfully for the treatment of osteoporosis in humans. In addition, cerium oxide (CeO) is an anti-stress agent applied in the biological system.Methods: This study was conducted to investigate the effect of SrR, CeO, and their combinations on tibia quality in broilers. A total of 384 one-day-old Ross chicks were divided into six treatments, with four replicates per treatment (16 birds per replicate).The control group was fed a standard diet, and other groups were fed SrR at levels 450, 900 mg/kg feed, CeO at levels 300 and 600 mg/kg feed and a combination of 450 SrR + 300 CeO mg/kg feed. Bone mineral density (BMD), bone mineral content (BMC), bone strength (BS), tibia area, tibia weight, bone Length, bone diameter, minerals in tibia bone of male broilers, alkaline phosphatase gene (ALP) and osteocalcin gene (OC) in male broilers were analysed. Results:The results showed that the addition of SrR and CeO had no significant influence (p > 0.01) on BMD, BMC, BS, bone weight, bone length and bone diameter. While there was a significant interaction between sex and treatments, especially in the combination group, BS in females significantly (p < 0.01) increased compared to the control group. Generally, females were found to be more responsive to treatments than males.Significant increases in gene expression were noticed in OC with the addition of low levels of SrR and CeO and mixed group compared to the control. The gene expression of ALP was increased significantly only in a combination group compared to the control group. Conclusion:It is concluded that SrR and CeO can be used as beneficial additives in the feed to improve the tibia quality of broilers.

“…For the metallic Sr target, dendritic strontium (MANUFACTURER) was rinsed with petroleum ether under an inert N 2 atmosphere, transferred to the 20 mm steel press and pressed under 10 tons as well, keeping it in a N 2 atmosphere when not in use as a target. Strontium metal quickly reacts with oxygen, water and carbon dioxide in the air to form its oxide, hydroxide and carbonate [123]. This makes the synthesis and survival of a powderbased Sr target very difficult.…”

“…(52) This conclusion, however, appears as diametrically opposed to the chapter 4 on the Handbook of Stable Strontium, also from 1981, which covers strontium as an inhibitory competitor to calcium deposition. (53)(54) The presence of strontium and its distribution throughout the sample can be very informative as strontium partitioning in water is temperature dependent. BECK et al…”

Comparative characterization of Upper-Pleistocene and modern day coral skeleton

Reefs are marine formations with biological, ecological and scientific value, such as harboring enormous biodiversity, protecting the shoreline from waves and marking sea-level and sea temperature evolution through epochs. Corals thrive in a variety of habitats according to their adaptations, having colonized depths from 0 to 2000 m from the sea surface and all latitudes across Earth. Reefs are mainly constituted by scleractinian corals, also known as stony corals, that synthesize a calcareous skeleton which act as scaffold for other organisms to shelter. The synthesized limestone captures carbon and performs an important role in Oceans' carbon cycle as carbon sinks. Since the decade of 1950, scleractinian corals are known for depositing aragonite which is a metastable calcium carbonate polymorph with rare natural occurrence, being calcite the most stable polymorph. Coral aragonite have shown interesting physical properties such as distorted aragonite unit cells and different phase transition temperatures when compared to geological aragonite, also notable mechanical strength capable of enduring oceanic tides. This work studies two colonial corals found in brazilian fauna for their age, chemical composition, crystalline structure and thermal behavior. Assessed specimens are Mussismilia hispida (Verrill, 1901) collected at 10 m deep and Lophelia pertusa (Linnaeus, 1758) collected 852 m deep, called Mh and Lp respectively. Results from radiocarbon dating tell that Mh is 22 years old modern coral and Lp is 12000 years old fossilized Pleistocene corals. Both samples are composed of aragonite and present trace elements originated in seawater, such as Mg, Na, Sr, S and Cl. Their thermal behavior and phase transition temperatures were proven to be distinct from other scleractinian corals previously studied. Although all corals presented the beginning of phase transition at 285 o C, our samples ended the process 310 o C, 100 o C cooler than the model corals, around 400 o C.This phenomenon is reputed to corals being of different clades, hence having a fundamental genetic difference, but this has to be studied further.
