In this study the influence of copper salts on the hypothalamic ovulatory hormone releasing factor was studied in vivo. 321 healthy adult female rabbits were used. 85 mcg of estradiol-17-beta-benzoate dissolved in 1 ml of sesame oil was injected intramuscularly for 2 days. Absence of ovulation and an active corpus luteum were confirmed by laparotomy. (For the measurement of LH rats were inj...
Established marinas act as gateways for human impact on the natural environment. One of the major ways this occurs is through the leaching of biocides from antifouling paints applied to marine vessels. These paints often contain copper, which can have an effect on non-target organisms, especially those in fouling communities within marinas. In this study, I hypothesized that the level of copper...
Strengthening of copper matrix by dispersion of metallic oxides particles as an efficient way to increase strength without losing thermal and electrical conductivities has been recognized for many years. Such a composite can withstand high temperatures and keep its properties. Such copper alloys have many applications especially in high temperature including resistance welding electrodes, elect...
The molecular responses of macrophages to copper-based nanoparticles have been investigated via a combination of proteomic and biochemical approaches, using the RAW264.7 cell line as a model. Both metallic copper and copper oxide nanoparticles have been tested, with copper ion and zirconium oxide nanoparticles used as controls. Proteomic analysis highlighted changes in proteins implicated in ox...
Human immunodeficiency virus type 1 (HIV-1) can be transmitted through breast-feeding and through contaminated blood donations. Copper has potent biocidal properties and has been found to inactivate HIV-1 infectivity. The objective of this study was to determine the capacity of copper-based filters to inactivate HIV-1 in culture media. Medium spiked with high titers of HIV-1 was exposed to copp...
Copper-catalyzed (or -mediated) asymmetric coupling reactions have received significant attention over the past few years. Especially the coupling reactions of aryl or alkyl halides with nucleophiles became a very powerful tool for the formation of C-C, C-N, C-O and other carbon-heteroatom bonds as well as for the construction of heteroatom-containing ring systems. This review summarizes the re...
The Holy Quran is God’s miracle and its scientific miracle aspects or wonders have been recognized by development of human scientific abilities. Stating the story of Zolqarnein and dam construction by him, verses 83 to 98 of Al-Kahf have pointed to some scientific points and facts regarding safety industry, impenetrability and consolidation of iron through putting a coating of copper on its sur...
HD (Huntington's disease) is caused by a polyQ (polyglutamine) expansion in the huntingtin protein, which leads to protein misfolding and aggregation of this protein. Abnormal copper accumulation in the HD brain was first reported more than 15 years ago. Recent findings show that copper-regulatory genes are induced during HD and copper binds to an N-terminal fragment of huntingtin, supporting t...
Diabetic individuals frequently suffer from skin pathologies, especially in their feet. Co-existing peripheral vascular disease and neuropathy exacerbate the capacity of these individuals to cope with infections, minor cuts and wounds, often leading to hard to treat and chronic ulcers. Copper has potent anti-fungal and antibacterial properties. Copper is also an essential trace element vital fo...
