Kidney stone disease affects people globally, with its prevalence on the rise. Given importance of elements’ function in formation kidney stones, this study investigated major and trace element content thirty samples from patients Beijing. The included inorganic components (calcium oxalate carbonate apatite) organic (uric acid). Results showed that Ca is much higher than components. Compared to...

Granular-shaped carbonate apatite (CO3Ap) bone substitute has demonstrated good clinical results, especially in the augmentation procedure, because it high osteoconductivity and can be replaced by a new bone. This study aimed to evaluate potential usefulness of CO3Ap for alveolar ridge preservation beagle dogs during 9-week follow-up period after surgery. Reconstruction extraction sockets with ...

Chemiluminescence (CL) from the cobalt(II)-catalyzed oxidation of luminol with hydrogen peroxide was dramatically enhanced by the presence of carbonate. The CL signal increases by several orders of magnitude over a wide range of concentrations of Co(II), luminol, or hydrogen peroxide. A limit of detection of 10 M for Co(II) and luminol and 10 M for hydrogen peroxide can be achieved. The CL emis...

In this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nHAp) composites. Cell culture and MTT assays were performed for in vitro biocompatibility. They show that nHAp can affect the proliferation of cells and the nHAp-starch and nHAP-gelatin biocomposites have no negative effect on the cell morphology, viability and p...

The controlled integration of organic and inorganic components confers natural bone with superior mechanical properties. Bone biogenesis is thought to occur by templated mineralization of hard apatite crystals by an elastic protein scaffold, a process we sought to emulate with synthetic biomimetic hydrogel polymers. Cross-linked polymethacrylamide and polymethacrylate hydrogels were functionali...

Hypochlorous acid and its conjugate base, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM). This may occur through the binding of myeloperoxidase directly to the glycosaminoglycans. The N-Cl group in the chloramides is a potential selective target for both reducing and o...
