Effects of Puerarin Combined with PLGA/TCP/Puerarin on Osteocalcin and Sialoprotein of Mandibular Defects.

In order to evaluate the effects of puerarin combined with poly lactic-co-glycolic acid (PLGA)/tricalcium phosphate (TCP)/puerarin on osteocalcin and sialoprotein of mandibular defects, the obtained rat jaw cells are analyzed. The surface morphology of osteoblast complex in the scaffold material group and puerarin combined scaffold material group is observed by a scanning electron microscope, and the growth and proliferation of osteoblasts are detected by the Cell Counting Kit-8 (CCK-8) method. Besides, the expression of type-I collagen (COL-I), osteocalcin (OC), and osteopontin (OPN) mRNA and related proteins in osteoblasts are detected by immunocytochemical staining.

miR-101-3p and miR-199b-5p promote cell apoptosis in oral cancer by targeting BICC1.

microRNAs (miRNAs) are involved in the carcinogenesis and progression of oral cancer. In this research, we aimed to identify the DE_miRNAs in oral cancer and the related molecular mechanisms. Using the GEO2R online tool, we identified 19 DE_miRNAs from the GSE115117 dataset and 3343 the DEGs from GSE74530 dataset.

[Investigation of machinable-infiltrated-ceramic glass infiltrating through the aluminous matrix].

This investigation was amied at the infiltrative capability of the machinable-infiltrated-ceramic(MIC) glass and the color of the composite after the MIC glass infiltrated through the aluminous matrix with different packing densities. By heating the components to 1100 degrees C for 2 hours, the MIC glass was made to infiltrate through the aluminous matrix with different packing densities. We measured the infiltrative depth and the color parameter and observed the rupture surface of the composite by means of SEM.
