The Effects of Irradiation on the Allergenicity of Crab Tropomyosins

食物过敏是当前食品安全领域较为突出的问题,辐照作为食物过敏原的加工处理方法之一,引起了学者的重视.作者对中华绒鳌蟹和三疣梭子蟹的主要过敏原(原肌球蛋白)进行了辐照处理,并分析了辐照处理对原肌球蛋白性质的影响.十二烷基磺酸钠-聚丙烯酰胺凝胶电泳结果显示,部分纯化的蟹类原肌球蛋白经7 kgy辐照处理后出现明显降解,10 kgy辐照处理后完全降解;蟹类过敏者血清的免疫印迹分析结果显示,部分纯化原肌球蛋白经3--7 kgy辐照处理后的过敏原性无明显变化,而10 kgy辐照处理后的过敏原性降低;兔抗锯缘青蟹原肌球蛋白抗体的免疫胶体金层析检测结果证实部分纯化原肌球蛋白经10 kgy辐照处理后的抗原性为阴性.但是,3--10 kgy辐照处理对整蟹原肌球蛋白及其过敏原性无明显影响,模拟胃液消化反应结果也表明3--10 kgy辐照处理对整蟹原肌球蛋白的酶解消化特性无明显影响.Food allergy is a prominent issue in the field of food safety.Irradiation treatment of food allergens has aroused extensive attention in the world.This study focused on the effects on the characteristic of the allergen(tropomyosins) from Chinese mitten crab and Swimming crab through irradiation.Analysis of SDS-PAGE showed that partially purified tropomyosins obviously degraded after treated with 7 kGy dose while almost degraded after 10 kGy treatment.Analysis of Western-Blotting with crab allergenic patients' sera indicated that the allergenicity of partially purified tropomyosins that treated by 10 kGy irradiation have an obvious decrease while that of partially purified tropomyosins treated by 3--7 kGy irradiation have slight differences.The results of the gold immunochromatography assay with animal antibody indicated that the antigenicity of partially purified tropomyosins was negative after treatment with 10 kGy irradiation.On the other hand,there was little effect on the allergenicity of tropomyosins from the entire Chinese mitten crab and the entire Swimming crab through irradiation.The simulating digestion experiment of gastric fluid also showed that there was little effect on the digestive stability of the tropomyosins from the entire crab through irradiation.国家自然科学基金(30571450;30871947);福建省科技计划重点项目(2006I0023;2006F5064)资

Preparatoin of Ultra-thin Ge-on-insulator with Ge-condensation Technique and O_3 Oxidation

采用锗(Ge)浓缩技术对绝缘层上锗硅(SGOI)材料进行循环氧化、退火,制备出19nm厚的绝缘层上锗(GOI)材料。然后对该GOI材料在400℃下进行O_3氧化,以进一步减薄GOI的厚度。采用高分辨透射电镜(HRTEM)、X射线反射(XRR)和原子力显微镜(AFM)等对样品形貌和结构进行表征。测试结果显示,O_3氧化减薄后的GOI晶体质量得到提高,且表面更加平整(厚度减薄2.5nm,粗糙度RMS降低0.26nm)。通过循环的O_3氧化减薄,可获得高质量的超薄(小于10nm)GOI材料,用于制备超薄高迁移率沟道Ge MOSFET。Ultra-thin germanium-on-insulator(GOI) was fabricated by modified Ge condensation process of SiGe on SOI substrate.The prepared GOI was then oxidized in an atomic layer deposition chamber with O_3 at 400 ℃ and the Ge oxides was removed with dilute hydrofluoric acid to get a thinner Ge layer.The GOI materials after O_3 oxidation were characterized by HRTEM、XRR and AFM measurements,indicating better crystal quality and smoother surface than those of the as-prepared GOI by Ge condensation techniques.When the GOI was oxidized at 400℃for 30 min,the thinning thickness was about 2.5nm and the surface roughness was reduced from 1.23 nm to 0.97 nm.High crystal quality ultra-thin(below 10nm)GOI can be expected by cyclic O_3 oxidation and thinning of Ge condensed GOI,which is one of the most promise candidates for high speed MOSFETs.国家自然科学基金项目(61474094,61176092);; 国家重点基础研究发展计划项目(2012CB933503,2013CB632103
