Effect of different calcium sulfate aspect ratios and chitosan addition methods on the interface properties of calcium sulfate/chitosan composite bone cement

open access: yesMedComm – Biomaterials and Applications
It is a great challenge to improve the properties of pure calcium sulfate bone cement. Here, two calcium sulfate hemihydrate powders with different aspect ratios were prepared, and three chitosan addition methods were adopted to investigate the effect on

The effect of calcium sulfate/calcium phosphate composite for the treatment of chronic osteomyelitis compared with calcium sulfate [PDF]

open access: yesAnnals of Palliative Medicine, 2020
Treatment of chronic osteomyelitis often requires surgical debridement in combination with bone defect reconstruction and antibiotics administration. We aimed at investigating and evaluating the effect of antibiotic-loaded absorbable calcium sulfate/calcium phosphate (CS/CP) composite as bone substitute in the treatment of chronic osteomyelitis ...

Calcium ameliorates the toxicity of sulfate salinity in Brassica rapa [PDF]

open access: yes, 2018
Salinity stress in Brassica, often only associated with osmotic effects and the toxicity of Na+, was more severe when applied as Na2SO4 than as NaCl, indicating that SO42− ions had toxic effects as well.
