In order to evaluate the effect of potassium silicate spray on the control of coffee leaf rust and coffee yield, an experiment was conducted during the 2005/2006 and 2006/2007 growing seasons on Coffea arabica cv. Catuaí Vermelho IAC 144, in a location situated at an elevation of 850 m in Coimbra, Minas Gerais, Brazil. The treatments consisted of: 1 potassium silicate; 2 potassium silicate + co...
Wilson's disease is a severe human disorder of copper homoeostasis. The disease is associated with various mutations in the ATP7B gene that encodes a copper-transporting ATPase, and a massive accumulation of copper in the liver and several other tissues. The most frequent disease manifestations include a wide spectrum of liver pathologies as well as neurological and psychiatric abnormalities. A...
Zinc pyrithione (ZPT) is an antimicrobial material with widespread use in antidandruff shampoos and antifouling paints. Despite decades of commercial use, there is little understanding of its antimicrobial mechanism of action. We used a combination of genome-wide approaches (yeast deletion mutants and microarrays) and traditional methods (gene constructs and atomic emission) to characterize the...
Pyruvaldehyde bis(thiosemicarbazone) (PTS) was tested alone and in combination with dietary copper sulfate on 10 tumor systems. Potentiation of the cancerostatic activity of PTS by copper sulfate occurred in 8 of the tumor systems: Sarcoma 180, Taper liver tumor (solid and ascites), Carcinoma 1025, Sarcoma T241, Ridgway osteogenic sarcoma, Mecca lymphosarcoma, and Walker Rat Carcinosarcoma 256 ...
Iron-copper interactions were described decades ago; however, molecular mechanisms linking the two essential minerals remain largely undefined. Investigations in humans and other mammals noted that copper levels increase in the intestinal mucosa, liver and blood during iron deficiency, tissues all important for iron homeostasis. The current study was undertaken to test the hypothesis that dieta...
in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...
THE ANTIBACTERIAL ECTIVITY OF COPPER NANOPARTICLES AND COMBINATION WITH COTRIMOXAZOLE AGAINST SALMONELLA TYPHI IN VITRO ANIMAL MODEL
This in vitro study evaluated the antibacterial effect of copper additives in silicone implants. Specimens of a standard silicone material used in breast augmentation and modified copper-loaded silicone specimens were prepared and incubated in a Staphylococcus epidermidis suspension (2 h, 37 degrees C). After the quantification of adhering staphylococci using a biofluorescence assay (Resazurin)...
Mechanisms of copper transport into purified mitochondrial suspensions prepared from the hepatopancreas of the Atlantic lobster Homarus americanus were investigated. Mitochondria were purified by combining methods of differential and Percoll-gradient centrifugation, and copper transport was studied using the copper-sensitive fluorescent dye Phen Green. Copper transport by this mitochondrial pre...
