Calcium phosphate materials are widely used as bone substitutes because of their properties close to those of the mineral phase of bones. Nevertheless, after several months, calcium phosphate-based materials release particles that may be phagocytosed by monocytes, leading to an inflammatory reaction. Strontium is well known to counteract the osteoporosis process, but little is known about its e...

INTRODUCTION Strontium ranelate is proven to reduce vertebral and non-vertebral fracture risk in osteoporosis. Concerns about cardiac safety have led to a new contraindication to strontium ranelate in patients with uncontrolled hypertension and/or current or past history of ischaemic heart disease, peripheral arterial disease and/or cerebrovascular disease. AREAS COVERED A literature search w...

The aim of this double-blinded, vehicle-controlled study was to test the antipruritic efficacy of topical strontium to relieve a nonhistaminergic form of itch that would be clinically relevant for chronic pruritic diseases. Itch induced with cowhage is mediated by PAR2 receptors which are considered to play a major role in itch of atopic dermatitis and possibly other acute and chronic pruritic ...

BACKGROUND Osteomalacia is now a rare disease in dialysis patients in developed countries since the withdrawal of aluminium overload. The involvement of fluoride and strontium in the pathogenesis of the disease has been suggested. The aim of this study was to investigate a possible association between osteomalacia in dialysis patients and the fluoride or strontium contents of bone. METHODS Of...

Abstract Lead zirconate (PbZrO 3 ) is considered the prototypical antiferroelectric material with an antipolar ground state. Yet, several experimental and theoretical works hint at a partially polar behaviour in this compound, indicating that polarization may not be completely compensated. In work, we propose simple ferrielectric structure for lead zirconate. First-principles calculations revea...

First principles calculations and Monte Carlo simulations reveal the impact of defect interactions on hydration barium-zirconate.

AIMS The study was performed to assess the safety of strontium ranelate in accordance with the ICH, E14 guidelines for QT/QT(c) studies. Its primary objective was to compare supratherapeutic repeated dosing of strontium ranelate (4 g day⁻¹ for 15 days) with placebo on the largest time-matched mean QT(c) variation, from baseline to under treatment values, in healthy subjects. METHODS Ninety-si...

The environmental benefits of fuel cells have been increasingly appreciated in recent years. Among candidate electrolytes for solid-oxide fuel cells, yttrium-doped barium zirconate has garnered attention because of its high proton conductivity, particularly in the intermediate-temperature region targeted for cost-effective solid-oxide fuel cell operation, and its excellent chemical stability. H...
