Panahi Z, Khakvar R, Aliasgharzad N, Zehtab S, Farshbaf PourAbad R (2023) The effect of copper nanoparticles on soft rot agent of potato, carrot and onion. Plant Pathology Science, 12(1):1-11. Doi: 10.2982/PPS.12.1.1 Abstract Introduction: Bacterial soft rot caused by Pectobacterium species is one of the important and common diseases in Potatoes and vegetables. Disinfection of tubers or...
persian gulf is known as one of the main areas of oil exploration and production, and in the meanwhile, this causes some problems for the contained water ecosystem by pollution. in this concern, one of the ways to face this problem is the use of oysters as biological treatment. sacostrea cucullata is one of endemic oyster species to persian gulf that is known as one of the important filterers. ...
Copper-ionophores that elevate intracellular bioavailable copper display significant therapeutic utility against prostate cancer cells in vitro and in TRAMP (Transgenic Adenocarcinoma of Mouse Prostate) mice. However, the pharmacological basis for their anticancer activity remains unclear, despite impending clinical trails. Herein we show that intracellular copper levels in prostate cancer, eva...
The gammaproteobacterium Xanthomonas citri pv. citri causes Asiatic citrus canker. Pathotype A strains have a broad host range, which includes most commercial citrus species, and they cause important economic losses worldwide. Control often relies on frequent copper sprays. We present here the complete genomes of six X. citri pv. citri copper-resistant strains.
Clear nosed skate, Raja erinacea were exposed to 0.10 (control), 0.52 or 1.73 microM copper and sculpin, Myoxocephalus octodecemspinosus were exposed to 0.10 or 1.73 microM copper (as CuSO4) in Salisbury Cove seawater for up to seven days. Skate gill copper concentrations increased 40-50 fold over background in response to copper exposure at both concentrations. In comparison, sculpin gill leve...
We evaluated the impact of the copper-silver ionization system in a hospital where hyperendemic nosocomial legionellosis and was present and all previous disinfection measures had failed. After implementation of the copper-silver ionization system, environmental colonization with Legionella species decreased significantly, and the incidence of nosocomial legionellosis decreased dramatically, fr...
A copper(I)-phosphine complex has been found to facilely promote the distannylation of alkynes with the aid of a base, where a catalytically generated Cu-Sn species serves as a key intermediate. The broad versatility of the copper catalysis has been demonstrated by the facile distannylation of unfunctionalized aliphatic alkynes, being hardly achievable with the conventional palladium catalysts.
The di-copper(II) cation, [Cu(2)(μ-terephthalate)(1,10-phen)(4)](2+), is a powerful, non-sequence-specific, minor-groove oxidizer of duplex DNA which, unlike copper(II) bis-1,10-phenanthroline chloride, operates independently of exogenous reagents. The agent displays excellent in vitro cytoxicity towards cisplatin-resistant ovarian cancer cells, producing intracellular reactive oxygen species u...
LCuOTf complexes [L = cyclic (alkyl)(amino)carbenes (CAACs) or N-heterocyclic carbenes (NHCs)] selectively promote the dehydrogenative borylation of C(sp)-H bonds at room temperature. It is shown that σ,π-bis(copper) acetylide and copper hydride complexes are the key catalytic species.
Evolutionary links between type 1 blue copper (T1 Cu), type 2 red copper (T2 Cu), and purple Cu(A) cupredoxins have been proposed, but the structural features and mechanism responsible for such links as well as for assembly of Cu(A) sites in vivo are poorly understood, even though recent evidence demonstrated that the Cu(II) oxidation state plays an important role in this process. In this study...
