Poly (glycerol-sebacate) (PGS) is an elastomeric biodegradable polymer which possesses the ideal properties of drug carriers. In the present study, we prepared a series of PGS implants (5-FU-PGSs) loaded with different weight percent of 5-fluorouracil (2, 5, 7.5 and 10%). We studied the infrared spectrum properties, in vitro degradation and drug release, in(More)
The development of biodegradable materials with controllable degradation properties is beneficial for a variety of applications. Poly(glycerol-sebacate) (PGS) is a promising candidate of biomaterials; so we synthesize a series of poly(glycerol, sebacate, glycolic acid) (PGSG) with 1:2:0, 1:2:0.2, 1:2:0.4, 1:2:0.6, 1:2:1 mole ratio of glycerol, sebacate, and(More)
Poly(glycerol-sebacate) (PGS) is an elastomeric biodegradable polyester that could be used as biodegradable drug carrier. We have previously prepared PGS implants doped with 5-fluorouracil (5-FU-PGSs) and found that 5-FU-PGSs exhibited an initial burst of 5-FU release during in vitro degradation. The synthesis temperature and time are two of the most(More)
Curcumin has multiple biological and pharmacological activities, including antioxidant, anti-inflammatory, antiviral, antibacterial, antifungal, and antitumor activities. However, the clinical use of curcumin is limited because of its poor oral absorption and extremely poor bioavailability. In order to overcome these limitations, we conjugate curcumin(More)
BACKGROUND Takayasu arteritis (TA) is a rare inflammatory arteriopathy of unknown etiology. The aim of this study was to investigate the genetic susceptibility to TA in a Chinese population. METHODS Four single nucleotide polymorphisms (SNPs) those locate in the IL12B region (rs56167332), the MLX region (rs665268), the FCGR2A/FCGR3A locus (rs10919543),(More)
Poly(glycerol-sebacate) (PGS) is an elastomeric biodegradable polyester. Our previous series of studies have showed that PGS has good biocompatibility. In view of the potential use of PGS in bioengineering, we attempt to characterize the PGS polymer with different ratio of glycerol and sebacic acid, and the cell adhesion and growth on these polymers. PGSs(More)
