Research ArticleOpen accessEvery word in the titleCross Talk between Iron Regulatory Proteins and Proinflammatory Molecules in Ovarian Cancer Patients Based on Menopausal StatusHaritha Padannapurath Manoj, Sudha Kuthethur, Reshma Kumarchandra et al.Micronutrient iron is postulated to contribute to the initiation of cancer mainly by the formation of Reactive Oxygen Species (ROS), the key signaling molecules of inflammatory reactions. Iron may also cause elevation of MMP9, a gelatinase responsible for remodeling extracellular matrix in cancer cells through the ROS pathway. Estrogen the hormone which decreases markedly in post menopause is also known … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 May 2024 · 4,491 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Application of Numerical Taxonomy Technique in the Iron Ore Flotation to Determine Appropriate pH and Particle Size DistributionRasoul Khosravi, Fahimeh Dehghani, Hossein Siavoshi et al.The numerical taxonomic technique is one of the multivariate decision-making techniques for assessment and ranking. It is widely used for planning and development studies. In this research, flotation experiments were conducted for Band Narges mine iron ore using different pH and particle size ranges. Numerical taxonomy technique, as one of the most important multi-attribute decision-making techniques, was used to determine … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 24 Dec 2020 · 6,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDoes Iron Modulate Cytokine Production by Desferrioxamine Treated Mononuclear Cells?Hanna Bessler, Meir DjaldettiIron is an essential element for maintaining the normal function of cellular and multicellular organisms and it is closely associated with inflammation and immunity. Macrophages and lymphocytes play an important role in its homeostasis. Hereby we have evaluated cytokine production by iron depleted and iron supplemented human peripheral blood mononuclear cells (PBMC) from healthy adult donors. Non-stimulated or stimulated PBMC … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 7 Jan 2018 · 6,845 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Hydrolysis Conditions for the Production of Iron-Binding Peptides from Scad (Decapterus maruadsi) Processing ByproductsWenting Zhang, Yanan Li, Jie Zhang, Guangrong HuangThe scad (Decapterus maruadsi) processing byproduct (SPB) was hydrolyzed by four commercial enzymes, namely, trypsin, flavourzyme, protamex and alcalase, for preparing high Iron-Binding Capacity (IBC) hydrolysate. Alcalase was the best choice for obtaining high IBC hydrolysate from SPB. Response surface methodology using a central-composite design was employed to optimize the enzymatic hydrolysis conditions with alcalase to obtain a maximum hydrolysate … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 17 Oct 2016 · 7,589 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis 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 accessEvery word in the titleFUNGAL LEACHING OF IRON ORE: ISOLATION, CHARACTERIZATION AND BIOLEACHING STUDIES OF PENICILLIUM VERRUCULOSUMNeha Chaudhary, Trina Banerjee, Neha Ibrahim, G. SibiPyrometallurgical and hydrometallurgical technologies for recovery of metals from low grade ores require high energy and capital costs. Use of microorganisms in leaching of mineral ores is gaining importance due to the implementation of stricter environmental rules. Microbes convert metal compounds into their water soluble forms and are biocatalysts of leaching processes. This study was performed to isolate and characterize … …Current Research in Microbiology, Vol. 5, Issue 1 · 25 Sep 2014 · 7,999 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRAPID 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 accessEvery word in the titleEffect of Chromium(VI) on Serum Iron and Removal of its Toxicity by Combining Deferasirox and Deferiprone Chelators in RatsS. Jamil A. Fatemi, Marzieh Iranmanesh, Faezeh Dahooee BaloochThe present research is aimed to characterize the potential efficiency of two chelators after chromium(VI) administration for 60 days following two doses of 15 and 30 mg kg-1 chromium(VI) per body weight daily to male rats. However, the hypothesis that the two chelators might be more efficient as combined therapy than as single therapy in removing chromium(VI) from bood serum … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 4 · 30 Oct 2013 · 7,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProtection of Terminalia belerica Roxb. Against Iron Overload Induced Liver Toxicity: An Account of Its Reducing and Iron Chelating CapacityBibhabasu Hazra, Rhitajit Sarkar, Nripendranath MandalExcess iron deposition in the liver catalyses the production of Reactive Oxygen Species (ROS) which in turn initiate oxidative damage of protein and nucleic acids leading to several human diseases. The fruits of Terminalia Belerica Roxb. (TB) has been most commonly used not only in stimulating gastrointestinal health, but also in treatment of various hepatic disorders. The present study was … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 3 · 20 Nov 2012 · 7,989 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCytotoxicity Studies of Superparamagnetic Iron Oxide Nanoparticles in Macrophage and Liver CellsAroonsri Priprem, Pramote Mahakunakorn, Chunpen Thomas, Ian ThomasSuperparamagnetic Iron Oxide Nanoparticles (SPIONs) prepared by simplified coprecipitation were attractive as MRI contrast agents and drug carriers which could internally be manipulated under the influence of an external magnetic field and also cancer treatment due to additional hyperthermia effects.
