The effect of copper on the production of extracellular trypsin-like proteases of Trichoderma harzianum T66 was examined. Trypsin-like protease enzyme activities were significantly enhanced in the presence of copper ion. It was demonstrated that instead of raising the activity of previously produced enzymes, copper ions are able to induce the secretion of extracellular trypsin-like proteases. S...

Bioelectrochemical systems (BESs) are a novel, promising technology for the recovery of metals. The prerequisite for upscaling from laboratory to industrial size is that high current and high power densities can be produced. In this study we report the recovery of copper from a copper sulfate stream (2 g L(-1) Cu(2+)) using a laboratory scale BES at high rate. To achieve this, we used a novel c...

The present study evaluated the single and mixed toxicities of commonly used antifouling biocides (copper pyrithione, Sea nine 211, dichlofluanid, tolylfluanid, and Irgarol 1051) on the early embryogenesis of sea urchin Strongylocentrotus intermedius. Their toxicities were quantified in terms of the median effective concentration (EC50) reducing the embryogenesis success by 50%. For individual ...

The Lapeh-Zanak copper deposit is located about 15 km east of Tehran, in the southern part of the Central Alborz Zone. The rock units exposed in this area include a sequence of volcanic and pyroclastic rocks (basalt, andesite, trachy-andesite and dacitic and vitric tuff) belonging to the Fajan Formation with the Paleocene-Lower Eocene age, which are cut by subvolcanic igneous masses with a comp...

UNLABELLED While research has identified an important contribution for metals, such as iron, in microbial pathogenesis, the roles of other transition metals, such as copper, remain mostly unknown. Recent evidence points to a requirement for copper homeostasis in the virulence of Cryptococcus neoformans based on a role for a CUF1 copper regulatory factor in mouse models and in a human patient co...

A one pot green three‐component coupling reaction of aldehyde, phenylacetylene, and amine derivatives in the presence of copper (II)–thioamide combination as a novel and efficient heterogeneous catalyst under solvent–free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to high yields. The key to this procedure was the generatio...

The effects of higher levels of chromium alone, and in combination with copper, were investigated in broiler chicks divided into seven equal groups. Group G served as control, receiving no treatment. Groups A, B and F received chromium chloride at a rate of 2 g/kg and nicotinic acid 150 mg/kg, while groups C, D and E received chromium chloride 8 mg/kg and nicotinic acid 150 mg/kg. Broilers in g...

Purpose: Copper in serum supports angiogenesis and inhibits replication of wild-type HSV-1. Copper chelation is currently being investigated as an antiangiogenic and antineoplastic agent in patients diagnosed with cancer. Herpes simplex virus–derived oncolytic viruses (oHSV) are being evaluated for safety and efficacy in patients, but several host barriers limit their efficacy. Here, we tested ...
