Metallothionein was purified under anaerobic conditions from livers of human fetuses ranging from 19 weeks gestational age to term. Homogeneous metallothionein obtained in the absence of reducing agents from the soluble fraction of the tissue which contained 24% and 85% of the total liver copper and zinc, respectively, had less than 1 g atom of copper and about 3.1 g atoms of zinc/mol. Extracti...

A three-dimensional, porous electrode composed of reticulated vitreous carbon (RVC) has been examined for the selective removal of metals by electrodeposition from single and multi-component solutions. A three-stage system was envisioned where each metal from a ternary mixture could be selectively removed in each stage. Single and multi-component solutions of copper, nickel, zinc and silver wer...

Nanoparticles have received much attention recently due to their use in cancer therapy. Studies have shown that different metal oxide nanoparticles induce cytotoxicity in cancer cells, but not in normal cells. In some cases, such anticancer activity has been demonstrated to hold for the nanoparticle alone or in combination with different therapies, such as photocatalytic therapy or some antican...

Recently, the rapid emergence of antibiotic-resistant pathogens has caused a serious health problem. Scientists respond to the threat by developing new antimicrobial materials to prevent or control infections caused by these pathogens. Polymer-based nanocomposite hydrogels are versatile materials as an alternative to conventional antimicrobial agents. Cross-linking of polymeric materials by met...

background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

BACKGROUND Toxic endothelial cell destruction (TECD) syndrome after intraocular ophthalmic surgery is rare and can result from exposure to a variety of toxins. During January 8 to 14, 1998, 6 patients developed TECD with corneal edema associated with unreactive or dilated pupils at Hospital A. METHODS A case patient was any Hospital A patient with TECD within 24 hours after surgery during Jan...

BACKGROUND Copper and zinc are the elements with numerous physiological activities. Copper (Cu) has an important role in angiogenesis and acts by increasing Vascular Endothelial Growth Factor (VEGF). Serum levels of copper will be increased in cancer incidence, progression and recurrence. The aim of this study was to measure blood levels of copper, zinc, and the ratio of Cu /Zn, as well as VEGF...

to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with th...
