Research ArticleOpen accessEvery word in the titleBiosynthesis and Evaluation of Zinc, Copper, and Methionine Feed Supplements Using Saccharomyces cerevisiae on Duck Performance in Minimal Water SystemsHendi Setiyatwan, Muhammad Rifqi IsmirajOptimizing duck performance under minimal water conditions is essential for sustainable poultry farming. Biosynthesizing essential feed supplements like Zinc (Zn), Copper (Cu), and methionine using Saccharomyces cerevisiae presents a promising method to enhance growth and meat quality. This study developed a biosynthesis method for Zn, Cu, and methionine supplements using S. cerevisiae and evaluated their effects on duck performance. In … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 11 Feb 2025 · 4,405 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExpression of Metallothionein-Like Protein 2B Gene Induced by Different Concentrations of Copper in White Spruce (Picea glauca)Megan McKergow, Kabwe NkongoloThe alterations to the expressions of metal transporter genes can induce metal ion uptake to maintain cell homeostasis when metal concentrations are low. Metallothioneins (MTs) are a class of low molecular mass (4-8 kDa), cysteine (Cys)-rich proteins that can bind metals via the thiol groups of their Cys residues. Studies on MT gene expressions in higher plants, such as conifers, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 25 Dec 2022 · 5,118 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeochemical and Petrology Properties of Zafarghand Index and Kahang Deposit of Porphyry Copper-MolybdenumMohsen Dehghanipoodeh, Hooshang Asadi Haroni, Mahin Mansouri Esfahani et al.The probability of the occurrence of porphyry copper ore associated with subduction zone of the Neo-Tethys ocean and volcanic arc of Iran (Urumieh-Dokhtar) justifies the necessity of exploration and prospection of this type of ore in Iran. Zafarghand index and Kahang deposit of porphyry copper-molybdenum located in Isfahan province, center of Iran using Satellite data interpretations were discovered in the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 19 Nov 2020 · 6,796 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge. The influence of contact … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 19 Oct 2020 · 6,920 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCopper (I)-Nicotinate Promotes Gene Expression of CYPs that Produce M1 and Q1 in Aflatoxicosed RatsMohammed Salah, Laila Mostafa, Tahia H. Saleem et al.Aflatoxin-contaminated food poses a serious risk to both human and animal health. Copper (1)-nicotinate (Cu+-nicotinate) complex potentiated the prophylactic effect against chronic aflatoxicosis in the experimental animals through the synthesis of less toxic metabolites M1 and Q1 which are easily excreted in urine. To investigate the action of the safety Cu+-nicotinate complex on gene expression of Cytochrome 450 (CYP450) system, … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 28 Jan 2020 · 8,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDifferential Gene Transcription in Red Oak (Quercus rubra) Genotypes Resistant to Copper ToxicityProulx Migueal, Paul Michael, Charnelle Djeukam, Kabwe NkongoloToxicity of metals is a major abiotic stressor of plants. Copper (Cu) is one of the most abundant metals in soils from the Greater Sudbury Region (GSR) due to its mining history. Recent studies have described several transporters and chelating proteins involved in copper resistance. Quercus rubra (Red Oak) is a common species that grows in metal contaminated soils in … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 11 Dec 2017 · 8,545 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCopper and Zinc Serum Level in Patients Receiving HemodialysisRahim Raoofi, Hossein Hakimelahi, Mohammad Sadegh Sanie et al.Decreased kidney function can accumulate trace elements. Increased trace elements can have toxic features. On the other hand, studies are showing that concentration of some trace elements could be decreased in chronic kidney disease patients as well. Because these patients are at risk for alterations of trace elements, we measured serum level of zinc and copper trace elements in hemodialysis … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 18 Aug 2015 · 7,360 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoval of Copper from Aqueous Solution using Tunisian ClayN. Boujelben, S. Gharab, F. Bouhamed et al.Natural adsorbents such as clay was used to replace expensive imported synthetic adsorbents. In this study, Scanning Electron Microscopy (SEM), Infrared spectroscopy and X-ray diffraction techniques were used to characterize the used sorbent (clays C). Batch experiments were performed to evaluate the effects of contact time, solution pH and temperature on copper removal onto used sorbent from aqueous solution. Equilibrium … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 15 Jun 2015 · 7,182 accessesView PDFCite
