In this study the regulation of squamous cell differentiation in several rat esophageal epithelial cell lines is examined. Nontumorigenic RE-149 cells undergo a program of squamous cell differentiation at confluence. This program of differentiation is influenced by the concentration of calcium in the medium and by the presence of retinoic acid. High calcium concentration stimulates terminal cel...

Benign primary bone tumors are commonly treated with intralesional curettage with or without the use of surgical adjuvants. The reconstructive approach to the resulting contained bone defects is controversial, and clinical practice is varied. Synthetic bone substitutes may provide early mechanical support while minimizing the risks of disease transmission, nonunion, infection, and donor-site mo...

BACKGROUND Urinary sulfate (SO4(2-)) and thiosulfate (S2O3(2-)) can potentially bind with calcium and decrease kidney stone risk. We modeled the effects of these species on the concentration of ionized calcium (iCa) and on supersaturation (SS) of calcium oxalate (CaOx) and calcium phosphate (CaP), and measured their in vitro effects on iCa and the upper limit of stability (ULM) of these salts. ...

Calcium sulfate exists in three forms, namely dihydrate or gypsum (CaSO4·2H2O), anhydrite (CaSO4), and hemihydrate bassanite (CaSO4·0.5H2O) depending on temperature, pressure, pH, formation conditions. The of calcium sulfates occurs widely nature many engineering settings. Herein, a dataset containing the experimental solubility data minerals, i.e., anhydrite, aqueous solutions is presented. co...

The article is devoted to the study of effect theKhojakulsandstone deposit Karakalpakstan on physical and mechanical properties Portland cement based clinker containing unbound calcium sulfate.

Most commercial water contains alkaline earth metal cations such as magnesium, calcium and barium, and anions such as carbonate, bicarbonate, sulfate, silicate, oxalate, phosphate, etc. Different combinations of these anions and cations will give rise to potentially scalant systems, such as calcium carbonate, calcium silicate, calcium sulfate, calcium oxalate, barium sulfate, magnesium sulfate,...

Despite the continuing advances in treatment of open fractures and musculoskeletal wounds, infection remains a serious complication. Current treatments to prevent infection utilize surgical debridement and irrigation, and high doses of systemic antimicrobial therapy. The aim of this work was to evaluate, in vitro, the potential of a fast-resorbing calcium sulfate pellet loaded with an antibioti...

Vitamin D3-3 beta-sulfate has been synthesized using pyridine sulfur trioxide as the sulfate donor. It has been shown to be pure by high performance liquid chromatography and spectral methods. Unlike previous reports, the product has been identified unambiguously as the 3 beta-sulfate ester of vitamin D3 by its ultraviolet, nuclear magnetic resonance, infrared, and mass spectra. The biological ...
