| 1 | Windformer∧TM向大容量发展的风力发电显示文摘随着新技术的突破,风力发电的容量已超过所有的预言,现在装机容量约13.4GW的电站,相当于20多个现代大型火电站。一种新技术名为“Windformer∧TM”的综合系统,在海上和沿海地区产生风力,并将电力传送到用户网上。Windformer可增加电力输出约20%,并使寿命期内的维修费用减半。采用ABB原Powerformer∧TM高压发电机先进的电缆技术,ABB工程师已开发了风力发电机,它既没有齿轮箱,又取消了变压器,使风力发电更加可靠,并减小了电气方面的损耗。 | 沈梁伟 Mikael Dahlgren | 2001 | 国外大电机2001，，1： | 3 |

| 6 | Effect of paracellular permeation enhancers on intestinal permeability of two peptide drugs,enalaprilat and hexarelin, in rats显示文摘Transcellular permeation enhancers are known to increase the intestinal permeability of enalaprilat,a 349 Da peptide,but not hexarelin(887 Da).The primary aim of this paper was to investigate if paracellular permeability enhancers affected the intestinal permeation of the two peptides.This was investigated using the rat single-pass intestinal perfusion model with concomitant blood sampling.These luminal compositions included two paracellular permeation enhancers,chitosan(5 mg/mL) and ethylenediaminetetraacetate(EDTA,1 and 5 mg/mL),as well as low luminal tonicity(100 mOsm) with or without lidocaine.Effects were evaluated by the change in lumen-to-blood permeability of hexarelin and enalaprilat,and the blood-to-lumen clearance of ^(51)chromium-labeled EDTA(CL_(Cr-EDTA)),a clinical marker for mucosal barrier integrity.The two paracellular permeation enhancers increased the mucosal permeability of both peptide drugs to a similar extent.The data in this study suggests that the potential for paracellular permeability enhancers to increase intestinal absorption of hydrophilic peptides with low molecular mass is greater than for those with transcellular mechanism-of-action.Further,the mucosal blood-to-lumen flux of ^(51)Cr-EDTA was increased by the two paracellular permeation enhancers and by luminal hypotonicity.In contrast,luminal hypotonicity did not affect the lumen-to-blood transport of enalaprilat and hexarelin.This suggests that hypotonicity affects paracellular solute transport primarily in the mucosal crypt region,as this area is protected from luminal contents by a constant water flow from the crypts. | David Dahlgren Tobias Olander Markus Sjoblom Mikael Hedeland Hans Lennernas | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 0 |
