| 1 | Comparative assessment of total polyphenols, antioxidant and antimicrobial activity of different tea varieties of Bangladesh显示文摘Objective: To determine the total polyphenol content, antioxidant activity and antibacterial properties of the extracts of different Bangladeshi tea varieties such as flowery broken orange pekoe, broken orange pekoe, red dust and green tea.Methods: Total phenolic and flavonoid contents were determined by Folin–Ciocalteu and aluminum chloride colorimetric assay, respectively.The antioxidant capacity was determined by ferric ion reducing antioxidant power and phosphomolybdenum method.Antibacterial activity was evaluated by disc diffusion method in agar plate and subsequently, the minimum inhibitory concentration was determined by broth dilution method.Results: Total phenolic and flavonoid contents were significantly higher(P < 0.05) in green tea compared to other three black tea varieties.The green tea also showed a higher free radical scavenging and antioxidant activities than all the other tea varieties tested(P < 0.05).In addition, the extracts of all four tea varieties showed inhibitory activity against several pathogenic bacteria and also the same trend of higher antimicrobial activity of green tea than other tea varieties was observed.Conclusions: Taken together, the results of this study demonstrated that Bangladeshi tea,especially the green tea, may act as a substitute for natural antioxidants and as a promising antibacterial agent for beneficial influence in human health. | Yead Morshed Nibir Ahmed Faisal Sumit Anwarul Azim Akhand Nazmul Ahsan Mohammad Shahnoor Hossain | 2017 | Asian Pacific Journal of Tropical Biomedicine2017，7，4： | 6 |
| 2 | Graphene-Coated Optical Fiber SPR Biosensor for BRCA1 and BRCA2 Breast Cancer Biomarker Detection:a Numerical Design-Based Analysis显示文摘This paper provides a simple hybrid design and numerical analysis of the graphene-coated fiber-optic surface plasmon resonance(SPR)biosensor for breast cancer gene-1 early onset(BRCA1)and breast cancer gene-2 early onset(BRCA2)genetic breast cancer detection.Two specific mutations named 916delTT and 6174delT in the BRCA1 and BRCA2 are selected for numerical detection of breast cancer.This sensor is based on the technique of the attenuated total reflection(ATR)method to detect deoxyribonucleic acid(DNA)hybridization along with individual point mutations in BRCA1 and BRCA2 genes.We have numerically shown that momentous changes present in the SPR angle(minimum:135%more)and surface resonance frequency(SRF)(minimum:136%more)for probe DNA with various concentrations of target DNA corresponding to a mutation of the BRCA1 and BRCA2 genes.The variation of the SPR angle and SRF for mismatched DNA strands is quite negligible,whereas that for complementary DNA strands is considerable,which is essential for proper detection of genetic biomarkers(916delTT and 6174delT)for early breast cancer.At last,the effect of electric field distribution in inserting graphene layer is analyzed incorporating the finite difference time domain(FDTD)technique by using Lumerical FDTD solution commercial software.To the best of our knowledge,this is the first demonstration of such a highly efficient biosensor for detecting BRCA1 and BRCA2 breast cancer.Therefore,the proposed biosensor opens a new window toward the detection of breast cancers. | Md.Biplob HOSSAIN Md.Muztahidul ISLAM Lway Faisal ABDULRAZAK Md.Masud RANA Tarik Bin Abdul AKIB Mehedi HASSAN | 2020 | Photonic Sensors2020，10，1： | 4 |
| 3 | 第25章 水文学100年进步显示文摘本章聚焦过去100年水文学进步。这一时期出现了从实用工程水文向水文科学基础研究的显著转变,包括了对地球系统科学的贡献。本章前3节回顾理论、观测和水文预报进展。在此基础上,讨论了全球水文、陆地-大气相互作用和耦合、生态水文学和水管理等主题,同时对出现的挑战和未来方向给出建议总结。尽管评述力争全面,但对于美国气象学会(AMS)文集的读者来说,本章还是在地表水文学和水文气象阐述更全面些。 | 克里斯塔·彼得斯-利达德 FAISAL HOSSAIN L.RUBYLEUNG NATE MCDOWELL MATTHEW RODELL FRANCISCO J.TAPIADOR F.JOE TURK ANDREW WOOD 贾朋群(编译) 李婧华(编译) | 2019 | 气象科技进展2019，9，S01： | 3 |
