| 1 | Anti-endothelial cell antibody rich sera from rheumatic heart disease patients induces proinflammatory phenotype and methylation alteration in endothelial cells显示文摘Rheumatic heart disease(RHD)is a major cause of cardiovascular morbidity and mortality in developing nations like India.RHD commonly affects the mitral valve which is lined by a single layer of endothelial cells(ECs).The role of ECs in mitral valve damage during RHD is not well elucidated.In here,anti-endothelial cell antibody from RHD patients has been used to stimulate the ECs(HUVECs and HMVECs).ECs proinflammatory phenotype with increased expression of TNFa,IL-6,IL-8,IFNg,IL-1b,ICAM1,VCAM1,E-selectin,laminin B,and vimentin was documented in both ECs.The promoter hypomethylation of various key inflammatory cytokines(TNFa,IL-6,and IL-8),integrin(ICAM1)associated with leukocyte transendothelial migration,and extracellular matrix genes(vimentin,and laminin)were also observed.Further,the in-vitro data was in accordance with ex-vivo observations which correlated significantly with the etiological factors such as smoking,socioeconomic status,and housing.Thus,the study sheds light on the role of ECs in RHD which is a step forward in the elucidation of disease pathogenesis. | Mukul Rastogi Subendu Sarkar Ankita Makol Rana Sandip Singh Uma Nahar Saikia Dibyajyoti Banerjee Seema Chopra Anuradha Chakraborti | 2018 | Genes & Diseases2018，5，3： | 5 |
| 2 | Study of cyanide removal from contaminated water using zinc peroxide nanomaterial显示文摘The present study highlights the potential application of zinc peroxide(ZnO_2)nanomaterial as an efficient material for the decontamination of cyanide from contaminated water. A process patent for ZnO_2 synthesis has been granted in United States of America(US Patent number 8,715,612; May 2014),South Africa,Bangladesh,and India. The ZnO_2 nanomaterial was capped with polyvinylpyrrolidone(PVP)to control the particle size. The PVP capped ZnO_2nanomaterial(PVP-ZnO_2)before and after adsorption of cyanide was characterized by scanning electron microscope,transmission electron microscope,X-ray diffractometer,Fourier transform infrared spectroscopy and time of flight-secondary ion mass spectrometry. The remaining concentration of cyanide after adsorption by PVP-ZnO_2 was determined using ion chromatograph. The adsorption of cyanide over PVP-ZnO_2 was also studied as a function of p H,adsorbent dose,time and concentration of cyanide. The maximum removal of cyanide was observed in p H range 5.8–7.8 within 15 min. The adsorption data was fitted to Langmuir and Fruendlich isotherm and it has been observed that data follows both the isotherms and also follows second order kinetics. | Himani Uppal S.

| 3 | Comparative study of leaching of silver nanoparticles from fabric and effective effluent treatment显示文摘Nano silver (Agn) is employed as an active antimicrobial agent, but the environmental impact of Agn released from commercial products is unknown. The quantity of nanomaterial released from consumer products during use should be determined to assess the environmental risks of advancement of nanotechnology. This work investigated the amount of silver released from three different types of fabric into water during washing. Three different types of fabric were loaded with chemically synthesized Ag nanoparticles and washed repeatedly under simulated washing conditions. Variable leaching rates among fabric types suggest that the manufacturing process may control the release of silver reaching the waste water treatment plants. In an attempt to recover the Agn for reutilization and to save it from polluting water, the effluents from the wash were efficiently treated with bacterial strains. This treatment was based on biosorption and was very efficient for the elimination of silver nanoparticles in the wash water. The process ensured the recovery of the Agn leached into the effluent for reutilization, thus preventing environmental repercussions. | Aneesh Pasricha Sant Lal Jangra Nahar Singh Neeraj Dilbaghi K.
