“…The hydrophobic surface was often modified by physical and chemical treatment to improve cell adhesion. The intrinsic hydrophobicity of PCL strongly limits its applications for tissue engineering scaffolds; thus, PCL nanofibers were frequently surface‐treated to improve their hydrophilicity . The addition of ASF into PCL nanofibers resulted in a smaller water contact angles than those of pure PCL, suggesting that the incorporation of ASF could improve the hydrophilicity of hybrid nanofibers.…”

To engineer tissue restoration, it is necessary to provide a bioactive, mechanically robust scaffold. Electrospun poly(ε‐caprolactone) (PCL) nanofiber is a promising biomaterial candidate with excellent mechanical properties, but PCL scaffolds are inert and lack natural cell recognition sites. To overcome this problem we investigated the incorporation of Antheraea pernyi silk fibroin (ASF) containing inherent RGD tripeptides with PCL in electrospinning process. The mixing ratios showed remarkable impact on the properties of hybrid nanofibers. Increasing PCL content significantly enhanced the mechanical properties of nanofibers. In particular, the mechanical properties were remarkably enhanced when PCL content increased from 50 wt% to 70 wt%. Moreover, the biological assays based on endothelial cells showed promoted cell viability when ASF content reached to 30 wt%. The data demonstrated that the nanofiber containing 70% of PCL and 30% of ASF achieved the most balanced performances for integrating the mechanical properties of PCL and the bioactivity of ASF. Furthermore, biomimetic alignment of 70PCL/30ASF nanofibers was achieved, which could support PC12 neuron‐like cell growth and guide neurite outgrowth, providing a potentially useful option for the engineering of oriented tissues. The results show that the PCL/ASF hybrid nanofibers can be considered as a promising candidate for tissue engineering scaffolds. POLYM. ENG.

Textiles can benefi t from using membranes capable to work as multi-compartment arrays, where diff erent and complementary functions can be allocated. Today, textiles markets face great competition but supply does not meet demand fully. Membrane science along with sensor technology is expected to bring innovation within the textiles manufacturing industry. Th e design of intelligent materials for the creation of ultra-smart textiles, which can provide self-maintenance, adaptability, auto-adjustment and long-distance communication, represent the future. Th is chapter is dedicated to deal with smart materials for the fabrication of sensing membranes showing adjustable functions, including breathability, heat exchange, self-cleaning, odor capture, drug delivery, power storage and communication. Every membrane function is discussed in relation to specifi c work activities and needs. Present and prospects of intelligent membranes for the creation of ultra-smart textiles are discussed as well.

“…5 Several published papers have analyzed the pharmacokinetics of some active constituents from a number of herbal medicines. [6][7][8][9][10] In this paper, the authors have developed a solid-phase extraction high performance liquid chromatography based method (SPE-HPLC) to simultaneously determine these four coumarins in rat plasma. Furthermore, the method is applied to investigate the pharmacokinetics of these coumarins in rat plasma after oral administration of YGC.…”

Foi desenvolvido um método simples, sensível e rápido de extração em fase sólida utilizando cromatografia liquida de alta eficiência (SPE-CLAE) para a determinação simultânea de quatro cumarinas, psoralen, isopsoralen, imperatorina e isoimperatorina, utilizando ostole como padrão interno. Utilizando este método, foi analisada a farmacocinética destas cumarinas em plasma de ratos após administração oral de uma cápsula "YIGONG" da medicina chinesa tradicional. Amostras de plasma foram pré-tratadas com extração em fase sólida utilizando cartuchos Extract-Clean TM e a separação dos extratos foi realizada com uma coluna Eurospher C 18 utilizando metanol-água como fase móvel. Os limites de quantificação foram 9,7 ng mL -1 para psoralen, 7,1 ng mL -1 para isopsoralen, 6,7 ng mL -1 para imperatorina e 3,0 ng mL -1 para isoimperatorina. As recuperações médias das quatro cumarinas contidas no plasma de ratos foram bem acima de 80%. As precisões determinadas para 6 dias estiveram sempre dentro de 10%. Concluiu-se que o método estabelecido é adequado para estudos farmacocinéticos destas quatro cumarinas em plasma de ratos.A simple, sensitive and rapid solid-phase extraction method by using high performance liquid chromatography (SPE-HPLC) was developed for simultaneous determination of four coumarins, psoralen, isopsoralen, imperatorin and isoimperatorin using osthole as internal standard. Using this method, pharmacokinetic of these coumarins in rat plasma was analyzed after oral administration of a traditional Chinese medicine "YIGONG" capsule. Plasma samples were pretreated with solidphase extraction using Extract-Clean TM cartridges, and separation of the extracts was performed on a Eurospher C 18 column using methanol-water as mobile phase. The quantification limits for psoralen, isopsoralen, imperatorin and isoimperatorin in rat plasma were 9.7, 7.1, 6.7 and 3.0 ng mL -1 , respectively. Average extract recoveries of the four coumarins from rat plasma were all over 80%. Precisions determined from 6 days were all within 10%. It was concluded that the established method is suitable for pharmacokinetic studies of these four coumarins in rat plasma.
