A copper deficiency myeloneuropathy was diagnosed secondary to chronic use of a zinc-containing dental fixative paste. The paste was discontinued and a copper supplementation was started. Resolution of symptoms was not achieved with intensive physiotherapy. The patient remains a wheelchair user though ...
Fungicidal synergistic effect of biogenically synthesized zinc oxide and copper oxide nanoparticles against Alternaria citri causing citrus black rot disease. Saudi J Biol Sci. 2022;29:88–95. Article CAS PubMed Google Scholar Wang ZL, Zhang X, Fan GJ, Que Y, Xue F, Liu YH. Toxicity ...
The toxicity of copper and zinc sulphates to immature Atlantic salmon (Salmo salar L.) was tested in soft water.The relation between concentration of metal and survival-time could be fitted by a straight line when logarithms were used. A sharp break in this relation marked the incipient lethal...
Example: Yeast Copper–Zinc Superoxide Dismutase As an example of a molecular replacement solution, we present the crystal structure of yeast copper–zinc superoxide dismutase (ySOD) by Drs. Hans Parge and John Tainer. When this structure was undertaken, two Cu-Zn superoxide dismutases...
In human cell lines and mouse models, the influx of zinc into chondrocytes upregulates a zinc-activated transcription factor, MTF1, which then induces expression of matrix-degrading enzymes, causing cartilage destruction38. For iron, a longitudinal cohort study observed that increased serum ferritin ...
Coprecipitation facilitates the incorporation of Zn into the lattice of Fe (hydr)oxide, which is a crucial mechanism causing low Zn bioavailability in widespread Zn-deficient soils. Zn isotopes are a potential indicator of the coprecipitation of Zn and Fe (hydr)oxides in soils. However, the Zn...
Zinc oxide and copper oxide nanoparticles are known for their promising biological activities. This study aims to synthesize zinc oxide nanoparticles and copper-doped zinc oxide nanoparticles to harness the combined cytotoxic and anticancer effects of th
In the case of series AMn, part of the Zn2+ was dissolved in the copper oxide matrix causing an increase in the reduction temperature of the copper oxide. 展开 关键词: copper-zinc oxide catalyst preparation (thermal decomposition coprecipitation) catalyst characterization (DRS DTA ESR XPS) ...
The flue gas chloride is effectively absorbed by water and dilute acid, causing it to enter the circulating acid. As a result, the chloride ion concentration in the acid solution increases after multiple cycles, often exceeding 2000 mg L−1 (Liu et al., 2023). 2.1.2 Wet metallurgy ...
all of the control samples exhibited loss of adhesion between the polymer coating and the copper wire, and the polymer insulation was brittle and cracked causing it to pull away from the substrate. The zinc-treated wire samples showed no flaws in the insulation which was still firmly bonded to...
