| 1 | A review of ecological risk assessment and associated health risks with heavy metals in sediment from India显示文摘Heavy metal(HM)pollution in sediment is a serious concern particularly in developing nations,warranting an extensive survey to understand the current situation and propose possible remedial measures.This paper compiles the data of HMs cadmium(Cd),iron(Fe),cobalt(Co),manganese(Mn),arsenic(As),lead(Pb),chromium(Cr),copper(Cu),zinc(Zn)and nickel(Ni)in aquatic sediment from India from 1979 to 2017.It was found that mean values of Cu,Co,Zn,Pb,As,and Cr in Indian sediment were high in comparison to the Australian Interim Sediment Quality Guidelines,World Surface Rock Average,and the Threshold Effect Level for freshwater ecosystems.Anthropogenic activities,lithogenic factors,and sand intrusion are the main factors associated with HM pollution as observed using cluster analysis and principal component analysis.The results of contamination indices indicate that HM contamination ranged from average to high,in the sediment.The ecological risk assessment results showed that 11%HMs present very high risk.The cancer risk,due to the high contents of Cd,As,and Cr the ingestion pathway,showed high risk of cancer through food/water contaminated with sediment.At source reduction of HMs in industrial effluents by effluent treatment plants,and plantation of phytoremediating rooted macrophytes in sediment may help in HM mitigation of the sediment. | Vinod Kumar Anket Sharma Shevita Pandita Renu Bhardwaj Ashwani Kumar Thukral Artemi Cerda | 2020 | International Journal of Sediment Research2020，35，5： | 4 |
| 2 | Lipid-polymer hybrid nanoparticles: Development & statistical optimization of norfloxacin for topical drug delivery system显示文摘Poly lactic acid is a biodegradable, biocompatible, and non-toxic polymer, widely used in many pharmaceuticalpreparations such as controlled release formulations, parenteral preparations, surgicaltreatment applications, and tissue engineering. In this study, we prepared lipid-polymer hybrid nanoparticlesfor topical and site targeting delivery of Norfloxacin by emulsification solvent evaporationmethod (ESE). The design of experiment (DOE) was done by using software to optimize the result, andthen a surface plot was generated to compare with the practical results. The surface morphology, particlesize, zeta potential and composition of the lipid-polymer hybrid nanoparticles were characterized bySEM, TEM, AFM, and FTIR. The thermal behavior of the lipid-polymer hybrid nanoparticles was characterizedby DSC and TGA. The prepared lipid-polymer hybrid nanoparticles of Norfloxacin exhibited anaverage particle size from 178.6 ± 3.7 nm to 220.8 ± 2.3 nm, and showed very narrow distribution withpolydispersity index ranging from 0.206 ± 0.36 to 0.383 ± 0.66. The surface charge on the lipid-polymerhybrid nanoparticles were confirmed by zeta potential, showed the value from t23.4 ± 1.5 mVto t41.5 ± 3.4 mV. An Antimicrobial study was done against Staphylococcus aureus and Pseudomonasaeruginosa, and the lipid-polymer hybrid nanoparticles showed potential activity against these two.Lipid-polymer hybrid nanoparticles of Norfloxacin showed the %cumulative drug release of 89.72% in24 h. A stability study of the optimized formulation showed the suitable condition for the storage oflipid-polymer hybrid nanoparticles was at 4 ± 2 C/60 ± 5% RH. These results illustrated high potential oflipid-polymer hybrid nanoparticles Norfloxacin for usage as a topical antibiotic drug carriers. | Vivek Dave Renu Bala Yadav Kriti Kushwaha Sachdev Yadav Swapnil Sharma Udita Agrawal | 2017 | Bioactive Materials2017，2，4： | 2 |

| 11 | In Situ TEM Observation of the Gasification and Growth of Carbon Nanotubes Using Iron Catalysts显示文摘We report the in situ transmission electron microscope (TEM) observation of the catalytic gasification and growth of carbon nanotubes (CNTs). It was found that iron catalysts can consume the CNTs when pumping out the precursor gas, acetylene, at the growth temperature, and reinitiate the growth when acetylene is re-introduced. The switching between gasification and growth of CNTs can be repeated many times with the same catalyst. To understand the phenomenon, thermogravimetric analysis (TGA) coupled with mass spectroscopy was used to study the mechanism involved. It was shown that the residual water molecules in the growth chamber of the TEM react with and remove carbon atoms of CNTs as carbon monoxide vapor under the action of the catalyst, when the precursor gas is pumped out. This result contributes to a better understanding of the water-assisted and oxygen-assisted synthesis of CNT arrays, and provides useful clues on how to extend the lifetime and improve the activity of the catalysts. | Xiaofeng Feng See Wee Chee Renu Sharma Kai Liu Xu Xie Qunqing Li Shoushan Fan Kaili Jiang | 2011 | Nano Research2011，4，8： | 1 |

| 14 | Staphylococcal bullous impetigo in a neonate显示文摘An otherwise healthy, full-term neonate presented at day 15 of life to the pediatric emergency with generalized papulo-pustular rash for 2 d. This was finally diagnosed as bullous impetigo caused by Staphylococcus aureus(S. aureus). The skin lesions decreased significantly after starting antibiotic therapy and drainage of blister fluid. There was no recurrence of the lesions on followup. This case of generalized pustular eruption due to S. aureus in a neonate is reported, as it poses a diagnostic dilemma and can have serious consequences if left untreated. | Shalini Dewan Duggal Tanisha Bharara Pragnya Paramita Jena Avinash Kumar Abha Sharma Renu Gur Sanjay Chaudhary | 2016 | World Journal of Clinical Cases2016，4，7： | 0 |
