This study proposes applying cold-bonded low calcium Class F fly ash (FFA) based artificial lightweight aggregate (ALWA) to partially replace natural fine aggregate in an ecological unfired brick with a low energy super-sulfated cement (SSC). To estimate the influence of ALWA on the brick properties, natural fine aggregate (FA) in the reference brick was substituted with ALWA at four different amounts of 25, 50, 75 and 100% by volume.

To compare the clinical efficacy of vancomycin calcium sulfate implantation and fenestration decompression in the treatment of sclerosing osteomyelitis. Both treatment methods can relieve pain effectively. Compared with fenestration decompression, vancomycin calcium sulfate implantation can shorten the treatment time effectively, control the infection better.

The management of displaced intra-articular calcaneal fractures (DIACFs) remains challenging and controversial. A prospective randomized controlled trial was conducted to compare percutaneous reduction, cannulated screw fixation and calcium sulfate cement (PR+CSC) grafting with minimally invasive sinus tarsi approach and plate fixation (MISTA) for treatment of DIACFs.

Managing with diabetic foot osteomyelitis (DFO) is challenging. Even after infective bone resection and thorough debridement, DFO is still difficult to cure and has a high recurrence rate. This retrospective study aims to compare the outcomes of two treatment methods, infected bone resection combined with adjuvant antibiotic-impregnated calcium sulfate and infected bone resection alone, for the treatment of diabetic foot osteomyelitis.

The research in the field of cementitious materials has brought towards many non-traditional binder systems. One of these systems, a ternary binder composed of calcium aluminate cement (CAC), ordinary Portland cement (OPC), and calcium sulfate (C$Hx), called ettringite binder, offers a possibility of very rapid development in mechanical strength. In this research, 18 different ternary mixtures were tested with two types of calcium sulfate, i.e. anhydrite and hemihydrate.

In seminiferous tubules, Sertoli cells provide structural and nutritional support for the developing germinal cells. Cellto-cell signaling and cell adhesion require proteoglycans expressed at the cell membrane. A preliminary biochemical and structural approach indicated that cell surface proteoglycans are mostly heparan sulfate proteoglycans (HSPG). Glypican-1, syndecans-1 and -4 were identified using a molecular approach.

In the leukemic macrophage cell-line THP-1, a fraction of the secreted matrix metalloproteinase 9 (MMP-9) is linked to the core protein of chondroitin sulfate proteoglycans (CSPG). Unlike the monomeric and homodimeric forms of MMP-9, the addition of exogenous CaCl2 to the proMMP-9/CSPG complex resulted in an active gelatinase due to the induction of an autocatalytic removal of the N-terminal prodomain.
