Streptococcus sanguis demonstrated a high affinity for hydrocarbon solvents. When aqueous suspensions of the organism were mixed with either hexadecane or toluene, the cells tended to bind to the nonaqueous solvent. Increases in temperature resulted in a greater affinity of cells for hexadecane. Interaction between the cells and hexadecane was also enhanced by dilute aqueous sodium chloride and...

BACKGROUND Filler injection for face augmentation is a common cosmetic procedure in the last decades, in our case report we describe long-term outcomes of a devastating complication of ophthalmic artery emboli following Calcium Hydroxylapatite filler injection to the nose bridge. CASE PRESENTATION A healthy 24-year-old women received a Calcium Hydroxylapatite filler injection to her nose brid...

OBJECTIVES/HYPOTHESIS Dorsal nasal irregularities after trauma, and various procedures such as excessive nasal hump resection, are major problems for patients who have undergone rhinoplasty. Many grafts have been described for the correction of dorsal nasal irregularities. In this study, we used an injectable implant, in combination with diced or block cartilage grafts, to test the efficacy of ...

The review is based on the analysis of 53 literature sources from PubMed, Google, Google Scholar, and Cochrane Library. Among substitutes for autogenous bone grafts in spine surgery, ceramic biomaterials are largest studied group, among which certain niche occupied by calcium phosphate ceramics (CPCs). Hydroxylapatite, tricalcium biphasic with all parts hydroxylapatite widely used surgery. adva...

We employed Gas expanded liquids (GXLs) technology to synthesize calcium carbonate-hydroxylapatite composite (CaCO3-HAp) nanoparticles and investigated the effects of reaction parameters on properties composites as well performance drug delivery agent using ibuprofen a model in simulated gastric fluid. Separately, carbonate hydroxylapatite have been used extensively pharmaceutical systems (DDS)...

Objective: Human jawbones consist mainly of hydroxylapatite. The aim of this study was to assess the structure of solid calcium phosphate compounds of the jaw bone (JB) in cases of normal and osteoporotic JBs. Design: The X-ray diffraction technique was used to analyze the structure of samples of cadavers’ jawbones. The experimental JB samples were taken from an osteoporotic and atrophic jawbon...

Metal immobilization may contribute to the environmental management strategy of dredged sediment landfill sites contaminated by metals. In a field experiment, amendment effects and efficiency were investigated, focusing on plants, springtails and bacteria colonisation, metal extractability and sediment ecotoxicity. Conversely to hydroxylapatite (HA, 3% DW), the addition of Thomas Basic Slag (TB...

The aging hand is a common area of concern for many patients. Until recently, adequate treatment options have been hampered by pain of injecting into the dorsum and, post-injection, by the absence of longevity of treatment. In this article, we describe the off-label use of the soft tissue filler calcium hydroxylapatite (CaHA; Radiesse) for hand rejuvenation. The product is inherently biocompati...
