Research ArticleOpen accessIn the keywordsA Study on Infections Caused By Metallo Beta Lactamase Producing Gram Negative Bacteria in Intensive Care Unit PatientsDebasrita Chakraborty, Saikat Basu, Satadal DasProblem statement: Metallo Beta Lactamse (MBL) producing bacteria is gradually increasing throughout the globe. There is no report of MBL producing bacteria from the city of Kolkata so far although it is a very big metropolice city in India. Thus this study was aimed to investigate the impact of this highly virulent group of bacteria in this city. Approach: In … …American Journal of Infectious Diseases, Vol. 6, Issue 2 · 30 Jun 2010 · 12,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Pseudomonas aeruginosa Infecting Bacteriophages from Swiftlet House Pond Water and Sewage in South Kalimantan, IndonesiaSiti Gusti Ningrum, Dyah Widhowati, Titin Yulinery et al.Pseudomonas aeruginosa is an opportunistic bacterium that may occur in animal-production environments and contribute to microbial contamination of animal-derived products. However, information on P. aeruginosa-infecting bacteriophages in artificial swiftlet-house environments remains limited. This study aimed to isolate and evaluate P. aeruginosa-infecting bacteriophages from the swiftlet-house environment in South Kalimantan, Indonesia. A total of 75 samples involving pond waters (n = … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 55 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Effect of Ulvan and Biosynthesized Silver Nanoparticles on Different Cell Lines Cytotoxicity and Gene ExpressionHadear Hanie Amin, Mohammed Ahmed Taha AbdelreheemUntil now, researchers searching for compounds that contribute for treating the most serious disease of this age, cancer. Researchers hope to contribute to this through this research. Activities of both Ulvan extracted from Ulva lactuca and silver nanoparticles (Ag-NPs) were examined against seven different cancer cell types called (Caco2 cells, A549 cells, Mcf7 cells, Hep2 cells, HepG2 cells, PC3 cells, … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 30 Jun 2020 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence and Genotypic Analysis and Antibiotic Resistance of Salmonella Species Isolated from Imported and Freshly Slaughtered ChickenWael K. Elfeil, Mahmoud E. Ezzat, Amira Fathi et al.Salmonellosis is a bacterial disease caused by different types of Salmonella species and associated with clinical disease in both human, birds and livestock species. Salmonellosis associated with severe economic impacts either from losses in poultry farm due to pathological picture losses, cost of medication, condemnation in slaughterhouse or zoonotic important. This study focused on the prevalence of Salmonellae in imported … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 28 May 2020 · 6,986 accessesView PDFCite
InvestigationOpen accessIn the abstractGenotypic Characterization of Antimicrobial Resistance-Associated Genes in Citrobacter Freundii Isolated from Patients with Urinary Tract Infection in Al-Najaf Governorate-IraqThualfakar Hayder, Ahmed Abduljabbar Jaloob AljanabyCitrobacter freundii is one of the most important pathogens that cause urinary tract infection in human because it harbors many types of antimicrobials resistance-associated genes. Therefore, this study aimed to evaluate the prevalence of antimicrobial resistance-associated genes citrobacter freundii isolated from patients with urinary tract infection in Al-Najaf governorate-Iraq. A total of 30 strains of citrobacter freundii isolated from urine … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 26 Jun 2019 · 8,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Marine Clay-Supported Nano Zero Valent IronHo Kuok How, Wan Zuhairi Wan YaacobThis study reports the preparation and characterization of marine clay nano zero valent iron (MC+nZVI) where marine clay acts as the composite material. Marine clay was air dried and pulverized before used. Basically, MC+nZVI was synthesized by chemical reduction method. The materials synthesized were left oven dried overnight at 50°C. The obtained materials were characterized by Field Emission Scanning Electron … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 26 Jun 2015 · 7,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Optimization of Plant Extract Loaded Nanoemulsion Mixtures for the Treatment of Inflammatory DisorderMukesh Gohel, Tejal Soni, Lal Hingorani et al.In current study, a nanoemulsion as drug delivery system (NE) of spray dried Boswellia Serrata Extract (BSE) was developed and characterized to compare it in vitro/Ex vivo diffusion with reference formulation. Pseudo-ternary phase diagrams were constructed by phase diagram by aqueous titration method, of which the evaluation method was improved for solubility, Droplet size and transmittance. The formulation of BSE-loaded … …Current Research in Drug Discovery, Vol. 1, Issue 2 · 26 Jan 2015 · 14,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractRAPID DEGRADATION OF AZO DYES USING NANO-SCALE ZERO VALENT IRONNabila Rahman, Zainal Abedin, M. Ali HossainIn the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM and … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 8 Apr 2014 · 8,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractSCANNING ELECTRON MICROSCOPE IMAGING OF AMYLOID FIBRILSEisuke Takai, Gai Ohashi, Ryuichi Ueki et al.This study demonstrated the applicability of Scanning Electron Microscopy (SEM) for the observation of amyloid fibrils without staining.
