Hydroxyapatite-lignin composite as a metallic implant-bone tissue osseointegration improver: experimental study in dogs Ciência Rural
Valente,Fabrício Luciani; Santos,Letícia Corrêa; Sepúlveda,Rodrigo Viana; Gonçalves,Gustavo Pereira; Eleotério,Renato Barros; Reis,Emily Correna Carlo; Borges,Andréa Pacheco Batista.
The study aimed to evaluate biocompatibility, osteoconduction and osseointegration of a pasty composite of hydroxyapatite (20%) and lignin (80%) as a promoter of metal implant and bone tissue integration. An intramedullary Schanz pin was implanted in both tibias of fifteen bitches. In the left tibia, the pin was coated with the biomaterial at the time of surgery. Marrow cavity was also filled with the biomaterial. Right limb did not receive the biomaterial, then constituting the control group. Tibias were harvested from five animals at 8, 60 and 150 days after surgery; three of them were analyzed by histological and biomechanical assessment and the two remaining tibias by X-ray diffraction. Results showed that the biomaterial is biocompatible, with...

Single-walled carbon nanotubes functionalized with sodium hyaluronate enhance bone mineralization BJMBR
Sá,M.A.; Ribeiro,H.J.; Valverde,T.M.; Sousa,B.R.; Martins-Júnior,P.A.; Mendes,R.M.; Ladeira,L.O.; Resende,R.R.; Kitten,G.T.; Ferreira,A.J..
The aim of this study was to evaluate the effects of sodium hyaluronate (HY), single-walled carbon nanotubes (SWCNTs) and HY-functionalized SWCNTs (HY-SWCNTs) on the behavior of primary osteoblasts, as well as to investigate the deposition of inorganic crystals on titanium surfaces coated with these biocomposites. Primary osteoblasts were obtained from the calvarial bones of male newborn Wistar rats (5 rats for each cell extraction). We assessed cell viability using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay and by double-staining with propidium iodide and Hoechst. We also assessed the formation of mineralized bone nodules by von Kossa staining, the mRNA expression of bone repair proteins, and the deposition of inorganic...
