BACKGROUND AND OBJECTIVES Idiopathic hypercalciuria is a frequent defect in calcium kidney stone formers that is associated with high intestinal calcium absorption and osteopenia. Characteristics distinguishing hypercalciuric stone formers from hypercalciuric patients without kidney stone history (HNSFs) are unknown and were explored in our study. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS...

The compositions and molecular structures of anhydrous and hydrated cements are established by using advanced solid-state nuclear magnetic resonance (NMR) spectroscopy methods to distinguish among different molecular species and changes that occur as a result of cement hydration and setting. One- and two-dimensional (2D) solid-state (29)Si and (27)Al magic-angle spinning NMR methodologies, incl...

CONTEXT Strontium ranelate reduces vertebral and nonvertebral fracture risk in postmenopausal osteoporosis. OBJECTIVE The objective of this study was to determine the efficacy and safety of strontium ranelate in osteoporosis in men over 2 years (main analysis after 1 year). DESIGN This was an international, unbalanced (2:1), double-blind, randomized placebo-controlled trial (MALEO [MALE Ost...

The efficiency of strontium selenite and selenite F broths in the isolation of S. typhi from 625 clinical stool specimens were compared. A total of 126 strains of S. typhi were detected. Of these, 96 (76%) were isolated with selenite F broth and 118 (94%) were isolated with strontium selenite broth. At the same time, the number of false positive isolates accruing to strontium selenite broth was...

Strontium (atomic symbol Sr) is a silvery-white alkaline earth metal that exists in several stable (e.g., Sr-86 and Sr-88) and several radioactive (e.g., Sr-89 and Sr-90) isotopic states. Stable strontium and its salts have many industrial uses, such as providing the red color in pyrotechnic devices such as tracer bullets, distress signal rockets, flares, and fireworks. In medicine, strontium b...

Contamination maps do not exist ; at best, strontium measurements are carried out sporadically by individual research groups. Furthermore, strontium is not at all looked for in the foodstuffsdatabase, which is used to calculate the radiation exposure of the population through taking in contaminated food. But it is known that relevant amounts of radioactive strontium were found in the teeth and ...

Line broadening of the hydrogen Balmer lines provides a sensitive measure of the number and energy of excited hydrogen atoms in a glow discharge plasma. The width of the 656.5 nm Balmer α line emitted from gas discharge plasmas having atomized hydrogen from pure hydrogen alone, hydrogen with magnesium or strontium, a mixture of 10% hydrogen and helium, argon, krypton, or xenon, and a mixture of...

The effect of pseudowollastonite (Pw) additions on the in vitro bioactivity and compressive strength of composites based on calcium aluminate cement (CAC) was studied. Composites were prepared by mixing calcium aluminate clinker with pseudowollastonite (5 and 10 wt%) at a w/c ratio of 0.4 (0.015M LiCl aqueous solution). In order to assess the in vitro bioactivity and compressive strength, compo...
