Abstract The experiment was carried out in a greenhouse at the University of Diyala’s Research Station for Department Horticulture and Landscaping College Agriculture during 2020–2021 academic year. Experiments were conducted on Catharanthus roseus cv. ‘Pacifica XP’ from November 24, 2020, to June 1, 2021, effects adding copper 0, 30, 45, 60 mg L -1 , foliar spraying with benzoic salicylic acid...

It has become clear that copper toxicity is playing a major role in Alzheimer's disease; but why is the brain copper toxicity with cognition loss in Alzheimer's disease so much different clinically than brain copper toxicity in Wilson's disease, which results in a movement disorder? Furthermore, why is the inorganic copper of supplement pills and in drinking water so much more damaging to cogni...

the interaction of copper oxide nanoparticles and copper ions and proteinase k from tritirachium album limber has been investigated employing uv spectroscopy and kinetics measurements. the aim of this study was to evaluate the effect of nanoparticles of cuo for proteinase k. in this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase k stabilit...

Nanobiotechnogy has been developed to synthesized copper oxide nanoparticle. This was carried out biologically using leaf extract of Psidium guajava as a reducing and stabilizing agent. Optical property showed color change from dark brown gold- yellow after the addition extract. The possible functional group in plant responsible for reduction CuONps identified belonging alkyl halide by FT-IR an...

Metallic copper surfaces rapidly and efficiently kill bacteria. Cells exposed to copper surfaces accumulated large amounts of copper ions, and this copper uptake was faster from dry copper than from moist copper. Cells suffered extensive membrane damage within minutes of exposure to dry copper. Further, cells removed from copper showed loss of cell integrity. Acute contact with metallic copper ...

Copper is an essential micronutrient that is toxic in excess. To maintain an adequate yet non-toxic concentration of copper, cells possess several modes of control. One involves copper uptake mediated by genes encoding proteins that play key roles in high affinity copper transport. These include the FRE1-encoded Cu2+/Fe3+ reductase and the CTR1 and CTR3-encoded membrane-associated copper transp...

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on nutritional physiological parameters grain yield common bean. The experimental design was randomized block, in 2 x 5 factorial scheme. first factor site application fertilization. second doses: 0, 1, 2, 3, 4 kg ha-1 (6 replicates). following were evaluated: leaf nitrogen contents, relative chloro...

to find the effects of spring foliar application of volck® mineral oil and its combination with fertilizer on the physiological, yield and quality characteristics of pistachio fruit, this research was done in the form of a randomized complete block design (rcbd) of 12 treatments and 3 replications on ohadi pistachio cultivar in chatrud of kerman in 2006 and 2007 for a duration of two years. the...

Located in the Puchuncaví Valley (PV) central Chile is one of most important and oldest industrial complexes (ICs) country. The PV affected by anthropogenic emissions from IC where industry a copper smelter refinery. In this context, study assessed profile, concentration, enrichment factors trace elements, both soil Cupressus macrocarpa leaves high-pollution-load area. leaf samples were taken f...
