| 1 | 镇江市古运河和金山湖河湖上覆水体和沉积物氮及有机质分布特征及污染评价显示文摘镇江市位于长江和京杭大运河'十字黄金水道'的交汇处,是我国历史上最为重要的水上交通枢纽之一,区域内水量充沛、河网密布.近年来,该区域水环境存在不同程度的退化,故调查镇江市主要河湖水体及沉积物污染现状,将为当地水环境质量的改善提供重要的基础数据.基于此,本研究选择镇江市典型河湖水体共21个点位(金山湖10个点位,古运河及其支流共11个点位),在冬夏两季采集上覆水及沉积物样品测定其理化指标和氮素含量,并通过有机指数及有机氮对沉积物污染程度进行评价.结果表明:(1)上覆水总氮(TN)浓度在冬夏季节分别介于1.95~15.71 mg·L^(-1)和0.64~12.09 mg·L^(-1)之间,平均值为4.01 mg·L^(-1)和4.07 mg·L^(-1),平均值浓度高于地表水Ⅴ类标准.上覆水氨氮(NH^(+)_(4)-N)浓度在季节上均表现为冬季<夏季,空间上则表现为河流>湖泊;(2)沉积物TN含量在冬夏两季分别介于394.61~3288.09 mg·kg^(-1)和869.21~3598.04mg·kg^(-1)之间,平均值为1928.58 mg·kg^(-1)和2068.40 mg·kg^(-1).湖泊沉积物TN、NH^(+)_(4)-N、硝态氮(NO^(-)_(3)-N)和有机氮(Org-N)含量均表现为冬季>夏季,而河流沉积物TN平均含量为冬季<夏季,NH^(+)_(4)-N和NO^(-)_(3)-N则表现为冬季>夏季,表明河流沉积物在季节上的分布规律更为复杂;空间上,冬夏两季沉积物NO^(-)_(3)-N表现为湖泊>河流,NH^(+)_(4)-N含量则表现为湖泊<河流.C/N结果表明研究区域沉积物有机质主要来源于内源污染;(3)湖泊和河流沉积物超过60%点位属于有机氮污染Ⅳ水平,即存在有机氮污染,而超过70%和54.55%的湖泊和河流沉积物处于有机指数Ⅱ类水平,即较清洁水平,表明镇江市河湖沉积物主要为氮素污染.以上研究结果将为镇江市河流水体及沉积物氮素控制提供重要的基础数据. | 原璐彬 邢书语 刘鑫 周晓红 Adelaide Angela Dadzie | 2021 | 环境科学2021，42，7： | 6 |
| 2 | 逆流聚能式超声预处理对谷朊蛋白酶解及其结构和热特性的影响显示文摘采取逆流聚能式超声波预处理技术提高谷朊蛋白酶解制备ACE抑制肽的效率。以谷朊蛋白酶解产物的ACE抑制率为指标,通过Box-Behnken响应面试验设计,建立逆流超声预处理谷朊蛋白的数学模型,优化技术参数。利用原子力显微镜、紫外光谱、荧光光谱、差示量热扫描仪对超声预处理后蛋白结构性质进行分析。结果表明,在超声波频率20 k Hz、功率446 W条件下,逆流超声预处理谷朊蛋白制备ACE抑制肽模型的最优条件为:脉冲超声工作时间4 s、间歇时间3 s、料液初始温度30℃、预处理时间30 min。在最优条件下,ACE抑制率为77.235%,IC50值为0.41 mg/m L,分别比未超声预处理的对照组提高了29.8%,降低了36.92%。结构及热特性分析表明,超声预处理改变了谷朊蛋白的微观形貌,使其表面粗糙度变大;蛋白分子发生了伸展,高级结构改变;热转变温度及热焓值下降。形貌、结构及热特性的变化表明超声波预处理使谷朊蛋白有利于酶解反应的进行。 | 张艳艳 马海乐 Rosemond Godbless Dadzie 叶晓非 曲文娟 李云亮 廖安妮 | 2017 | 中国食品学报2017，17，3： | 3 |
| 3 | Is onchocerciasis elimination in Africa feasible by 2025:a perspective based on lessons learnt from the African control programmes显示文摘Background:Onchocerciasis is found predominantly in Africa where large scale vector control started in 1974.Registration and donation of ivermectin by Merck&Co in 1987 enabled mass treatment with ivermectin in all endemic countries in Africa and the Americas.Although elimination of onchocerciasis with ivermectin was considered feasible only in the Americas,recently it has been shown possible in Africa too,necessitating fundamental changes in technical and operational approaches and procedures.Main body:The American programme(OEPA)operating in onchocerciasis epidemiological settings similar to the mild end of the complex epidemiology of onchocerciasis in Africa,has succeeded in eliminating onchocerciasis from 4 of its 6 endemic countries.This was achieved through biannual mass treatment with ivermectin of 85%of the eligible population,and monitoring and evaluation using serological tests in children and entomological tests.The first African programme(OCP)had a head start of nearly two decades.It employed vector control and accumulated lots of knowledge on the dynamics of onchocerciasis elimination over a wide range of epidemiological settings in the vast expanse of its core area.OCP made extensive use of modelling and operationalised elimination indicators for entomological evaluation and epidemiological evaluation using skin snip procedures.The successor African programme(APOC)employed mainly ivermectin treatment.Initially its objective was to control onchocerciasis as a public health problem but that objective was later expanded to include the elimination of onchocerciasis where feasible.Building on the experience with onchocerciasis elimination of the OCP,APOC has leveraged OCP’s vast modelling experience and has developed operational procedures and indicators for evaluating progress towards elimination and stopping ivermectin mass treatment of onchocerciasis in the complex African setting.Conclusions:Following the closure of APOC in 2015,implementation of onchocerciasis elimination in Africa appears to overlook all the experience that has been accumulated by the African programmes.It is employing predominantly American processes that were developed in a dissimilar setting from the complex African onchocerciasis setting.This is impeding progress towards decisions to stop intervention in many areas that have reached the elimination point.This article summarizes lessons learned in Africa and their importance for achieving elimination in Africa by 2025. | Yankum Dadzie Uche V.Amazigo Boakye A.Boatin Azodoga Seketeli | 2018 | Infectious Diseases of Poverty2018，7，1： | 3 |
