| 4 | Cytotoxic activity and phytochemical analysis of Arum palaestinum Boiss.显示文摘Objective: To evaluate the in vitro cytotoxic activity of the fractionated extract as well as isolated compounds of Arum palaestinum Boiss.(A. palaestinum)(black calla lily), and to identify the volatile components which may be responsible for the potential antitumor activity.Methods: A. palaestinum was collected from its natural habitats and subjected to phytochemical analysis for separation of pure compounds. In vitro cytotoxic activity was investigated against four human carcinoma cell lines Hep2, He La, Hep G2 and MCF7 for the fractionated extract and isolated compounds. While, the diethyl ether fraction was subjected to GC–MS analysis as it exhibited the most potent cytotoxic effect to evaluate the active constituents responsible for the cytotoxic activities.Results: Four flavonoid compounds were isolated(luteolin, chrysoeriol, isoorientin,isovitexin) from the diethyl ether and ethyl acetate. The extracts and the pure isolated compounds showed a significant high antiproliferative activity against all investigated cell lines. The GC–MS analysis revealed the separation and identification of 15 compounds representing 95.01% of the extract and belonging to different groups of chemical compounds.Conclusions: The present study is considered to be the first report on the cytotoxic activities carried out on different selected fractions and pure compounds of A. palaestinum to provide evidences for its strong antitumor activities. In addition,chrysoeriol and isovitexin compounds were isolated for the first time from the studied taxa. | Mai Mohammed Farid Sameh Reda Hussein Lamiaa Fawzy Ibrahim Mohammed Ali El Desouky Amr Mohammed Elsayed Ahmad Ali El Oqlah Mahmoud Mohammed Saker | 2015 | Asian Pacific Journal of Tropical Biomedicine2015,5,11: | 1 |
| 5 | Microalgae-based wastewater treatment:Mechanisms,challenges,recent advances,and future prospects显示文摘The rapid expansion of both the global economy and the human population has led to a shortage of water resources suitable for direct human consumption.As a result,water remediation will inexorably become the primary focus on a global scale.Microalgae can be grown in various types of wastewaters(WW).They have a high potential to remove contaminants from the effluents of industries and urban areas.This review focuses on recent advances on WW remediation through microalgae cultivation.Attention has already been paid to microalgae-based wastewater treatment(WWT)due to its low energy requirements,the strong ability of microalgae to thrive under diverse environmental conditions,and the potential to transform WW nutrients into high-value compounds.It turned out that microalgae-based WWT is an economical and sustainable solution.Moreover,different types of toxins are removed by microalgae through biosorption,bioaccumulation,and biodegradation processes.Examples are toxins from agricultural runoffs and textile and pharmaceutical industrial effluents.Microalgae have the potential to mitigate carbon dioxide and make use of the micronutrients that are present in the effluents.This review paper highlights the application of microalgae in WW remediation and the remediation of diverse types of pollutants commonly present in WW through different mechanisms,simultaneous resource recovery,and efficient microalgae-based co-culturing systems along with bottlenecks and prospects. | Abdallah Abdelfattah Sameh Samir Ali Hassan Ramadan Eslam Ibrahim El-Aswar Reham Eltawab Shih-Hsin Ho Tamer Elsamahy Shengnan Li Mostafa M.El-Sheekh Michael Schagerl Michael Kornaros Jianzhong Sun | 2023 | Environmental Science and Ecotechnology2023,,1: | 0 |
| 6 | 鲊辣椒生香酵母的分离筛选鉴定及其应用研究显示文摘从自然发酵鲊辣椒中以嗅闻法结合总酯含量作为生香酵母的筛选依据分离筛选到1株生香酵母,经鉴定并分类命名为库德里阿兹威氏毕赤酵母菌(Pichia kudriavzevii)Y50,为探究该菌株混菌发酵生产鲊辣椒的品质提升作用,将Y50与植物乳杆菌混合发酵鲊辣椒(C),以自然发酵的鲊辣椒(A)以及接种植物乳杆菌发酵的鲊辣椒(B)为对比研究对象,对3种鲊辣椒的基本理化指标、辣椒碱、有机酸和挥发性成分进行比较分析。结果表明,3种鲊辣椒pH值、总酸、亚硝酸盐、胡萝卜素含量较为接近,但鲊辣椒C中有机酸含量达(25.46±0.32)g/kg,比鲊辣椒A和鲊辣椒B分别高出57.8%和32.2%。鲊辣椒A、B、C中分别检出挥发性风味物质90种、67种和72种,其中鲊辣椒C的挥发性物质含量最高,为(10101.11±99.04)μg/kg,酯类、醇类、醛类、酸类挥发性物质含量均有提高,相比A、B分别提升了75%、358%、106%、23%和102%、59%、68%、51%,赋予鲊辣椒更浓郁的酯香、花香和果香,说明添加生香酵母Y50能提升鲊辣椒整体的风味品质,通过气味活度值(odor activity value,OAV)的计算,共检出22种OAV>1的香气化合物,这些关键香味物质赋予了鲊辣椒特有的香气特征,其中β-紫罗兰酮、2-甲基丁酸乙酯、己酸己酯、正庚醇、(+)-柠檬烯、庚醛、愈创木酚是构成鲊辣椒C风味的关键物质。试验表明Y50具有进一步应用于鲊辣椒生产的潜力。 | 姚红 尹小庆 颜宇鸽 阚建全 武运 戚晨晨 王治国 Sameh AWAD Amel IBRAHIM 杜木英 | 2023 | 食品与发酵工业2023,49,17: | 0 |
| 7 | 模糊数学感官评价结合响应面法优化鲊辣椒混菌发酵工艺显示文摘以小米椒和玉米粉为原料,植物乳植杆菌XZ3和生香酵母菌Y50为菌种,制作一款混菌发酵鲊辣椒。以鲊辣椒的模糊感官评分为响应值,采用Box-Behnken中心组合设计试验对鲊辣椒混菌发酵工艺进行优化,并测定其产品的功能性成分。结果表明,混菌发酵鲊辣椒的最优发酵条件为:植物乳植杆菌XZ3与生香酵母菌Y50的比例为1∶1、混菌添加量为2.5%、食盐添加量为4%、发酵时间6 d。在此优化条件下,鲊辣椒的感官评分为8.45分。与不接种自然发酵鲊辣椒和利用植物乳植杆菌XZ3纯种发酵的鲊辣椒进行对比,发现优化后的混菌发酵鲊辣椒的香气更突出。进一步测定其功能性成分发现,混菌发酵鲊辣椒中多酚组分含量最高且种类检出最多,其总酸含量、辣椒碱含量和总黄酮含量都显著高于自然发酵鲊辣椒。除此之外,相比于其他两种,混菌发酵鲊辣椒中甜味氨基酸的含量上升,苦味氨基酸的比例降低。该研究为混菌发酵鲊辣椒的生产提供了有益参考。 | 黄璐晗 尹小庆 阚建全 武运 戚晨晨 彭芸 SAMEH Awad AMEL Ibrahim 杜木英 | 2024 | 食品与发酵工业2024,50,7: | 0 |
| 8 | Efficient Hardware Design of a Secure Cancellable Biometric Cryptosystem显示文摘Biometric security is a growing trend,as it supports the authentication of persons using confidential biometric data.Most of the transmitted data in multi-media systems are susceptible to attacks,which affect the security of these sys-tems.Biometric systems provide sufficient protection and privacy for users.The recently-introduced cancellable biometric recognition systems have not been investigated in the presence of different types of attacks.In addition,they have not been studied on different and large biometric datasets.Another point that deserves consideration is the hardware implementation of cancellable biometric recognition systems.This paper presents a suggested hybrid cancellable biometric recognition system based on a 3D chaotic cryptosystem.The rationale behind the utilization of the 3D chaotic cryptosystem is to guarantee strong encryption of biometric templates,and hence enhance the security and privacy of users.The suggested cryptosystem adds significant permutation and diffusion to the encrypted biometric templates.We introduce some sort of attack analysis in this paper to prove the robustness of the proposed cryptosystem against attacks.In addition,a Field Programmable Gate Array(FPGA)implementation of the pro-posed system is introduced.The obtained results with the proposed cryptosystem are compared with those of the traditional encryption schemes,such as Double Random Phase Encoding(DRPE)to reveal superiority,and hence high recogni-tion performance of the proposed cancellable biometric recognition system.The obtained results prove that the proposed cryptosystem enhances the security and leads to better efficiency of the cancellable biometric recognition system in the presence of different types of attacks. | Lamiaa A.Abou Elazm Walid El-Shafai Sameh Ibrahim Mohamed G.Egila H.Shawkey Mohamed K.H.Elsaid Naglaa F.Soliman Hussah Nasser AlEisa Fathi E.Abd El-Samie | 2023 | Intelligent Automation & Soft Computing2023,,4: | 0 |
