1Characterizing Thermal Augmentation of Convection-Enhanced Drug Delivery with the Fiberoptic Microneedle Device显示文摘Convection-enhanced delivery(CED) is a promis ing technique leveraging pressure-driven flow to increase penetration of infused drugs into interstitial spaces. We have developed a fiberoptic microneedle device for inducing local sub-lethal hyperthermia to further improve CED drug distribution volumes, and this study seeks to quantitatively characterize this approach in agarose tissue phantoms. Infusions of dye were conducted in 0.6%(w/w) agarose tissue phantoms with isothermal conditions at 15 °C, 20 °C, 25 °C, and 30 °C. Infusion metrics were quantifled using a custom shadowgraphy setup and imageprocessing algorithm. These data were used to build an empirical predictive temporal model of distribution volume as a function of phantom temperature. A second set of proof of-concept experiments was conducted to evaluate a novel fiberoptic device capable of generating local photothermal heating during fluid infusion. The isothermal infusions showed a positive correlation between temperature and distribution volume, with the volume at 30 °C showing a 7-fold increase at 100 min over the 15 °C isothermal case. Infusions during photothermal heating(1064 nm at 500 mW) showed a similar eff ect with a 3.5-fold increase at 4 h over the control(0 mW). These results and analyses serve to provide insight into and characterization of heat-mediated enhancement of volumetric dispersal.R.Lyle Hood Rudy T.Andriani Tobias E.Ecker John L.Robertson Christopher G.Rylander 2015Engineering2015,1,3:2

9切花的国际贸易显示文摘七十年代,切花和切枝、切叶的国际贸易额有了很大增长,这主要是由于在中南美洲(特别是哥伦比亚)、以色列、肯尼亚,以及近年又在墨西哥建成了一些新的生产基地;另一方面,发达的花卉生产中心如荷兰、意大利和加拿大也加强了他们的国际性花卉贸易活动。George L.Staby Jerry L.Robertson 邵健文 1984世界农业1984,,12:0
