Hydroxyapatite (HA) coatings on titanium (Ti) substrates have attracted much attention owing to the combination of good mechanical properties of Ti and superior biocompatibility of HA. Incorporating silver (Ag) into HA coatings is an effective method to impart the coatings with antibacterial properties. However, the uniform distribution of Ag is still a(More)
Fibronectin adsorption on biomaterial surfaces plays a key role in the biocompatibility of biomedical implants. In the current study, the adsorption behavior of the 7-10th type III modules of fibronectin (FN-III7-10) in the presence of hydroxyapatite (HAP) was systematically investigated by using molecular docking approach. It was revealed that the FN-III10(More)
The macro-pore sizes of porous scaffold play a key role for regulating ectopic osteogenesis and angiogenesis but many researches ignored the influence of interconnection between macro-pores with different sizes. In order to accurately reveal the relationship between ectopic osteogenesis and macro-pore sizes in dorsal muscle and abdominal cavities of dogs,(More)
From the aerial parts of Senecio dianthus, five eremophilane glucosides (1, 2, 4–6) and one new eremophilenolide (7) were isolated, together with sixteen known compounds (3, 8–22). Their structures and relative configurations were elucidated on the basis of extensive spectroscopic analysis, including HR-ESI-MS, X-ray, CD, 1D- and 2D-NMR experiments.
A novel steroidal alkaloid, suchengbeisine (1), along with two known steroidal alkaloids, N-oxide of verticinone (2) and zhebeininoside (3), were isolated from the bulbs of Fritillaria shuchengensis S. C. Chen et S. F. Yin. The structures of these compounds were elucidated by intensive spectroscopic methods, including NMR, IR, CD and MS.
Biodegradable polymer particles present a promising approach for intracellular delivery of drugs, proteins, and nucleic acids. Poly-d,l-lactide-poly(ethylene glycol) (PELA) copolymers with different weight ratios of polyethylene glycol (PEG) were used as drug carriers in the present study. PELA particles entrapped with fluorescein isothiocyanate (FITC) as a(More)
