The present study revealed the damaging effects of copper and hydrogen peroxide on DNA isolated from human blood in in vitro. Ultra violet spectral studies showed that copper and H2O2 alone (at 20 mM) caused destabilization of DNA structure. Notwithstanding, the effect was more prominent in combination of copper and H2O2. Further, agarose gel electrophoretic studies revealed that neither copper...

The application of iron and copper in combination with Rhizobium was studied with on the growth of Vignamungo(L.).The Vignamungo(L.) seeds were grown in different concentrations (0, 30, 60 and 90ppm) of iron and copper individually in natural conditions. This study has shown that copper and iron metal ions have stimulatory effects on plant growth at low concentration but it turns toxic at high ...

wilson's disease is a rare but treatable condition with variable clinical presentations. its diagnosis depends on a combination of clinical and laboratory findings. we evaluated the clinical and laboratory findings in children with wilson's disease (wd). twenty -seven children (4-14 years, 59.2 % male, 40.7% female) with confirmed wd were evaluated between 1994 and 2003 at imam khomei...

The high-affinity copper transporter (Ctr1; SCLC31A1) plays an important role in regulating copper homeostasis because copper is an essential micronutrient and copper deficiency is detrimental to many important cellular functions, but excess copper is toxic. Recent research has revealed that human copper homeostasis is tightly controlled by interregulatory circuitry involving copper, Sp1, and h...

A study of the effect of certain metals on the prevention of nutritional anemia in the rat has been reported in the preceding paper (4). Animals receiving a mixture of manganese, cobalt, nickel, and zinc with iron developed a progressive anemia and died, whereas those receiving the same mixture with iron and copper developed an abnormally high hemoglobin value at the age of 7 to 9 weeks. After ...

Copper-catalyzed asymmetric allylation of chiral N-tert-butanesulfinyl imines has been described. Dual stereocontrol, through the combination of a chiral auxiliary and a chiral copper complex, has played an important role in achieving the nearly perfect diastereoselectivities (all dr > 99 : 1), especially for ketimine substrates.

Venerid clam, Paphia malabarica Chemnitz, is the commercially exploited species distributed exclusively in Vembanad Lake and Ashtamudi estuary, along the south west coast of India. In this study, the survival rate and development of P. malabarica larvae were studied for 3 days in ambient salinity (33), copper (2.5 microg Cu2+ l(-1)), reduced salinities (25 and 20) and a combination of copper in...

The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...

Under ambient conditions, toluene can be oxidized selectively to benzaldehyde, an essential compound in the chemical industry. Copper(I) complexes were applied combination with [Ru(bipy)3](PF6)2 and dioxygen as oxidant. A peroxido copper complex is formed active species. The copper(II) obtained after oxidation photochemically reduced starting copper(I) species, process repeated. More informatio...
