Cu(II) inhibition of the proton translocation machinery of the influenza A virus M2 protein. (1/7019)

The homotetrameric M2 integral membrane protein of influenza virus forms a proton-selective ion channel. An essential histidine residue (His-37) in the M2 transmembrane domain is believed to play an important role in the conduction mechanism of this channel. Also, this residue is believed to form hydrogen-bonded interactions with the ammonium group of the anti-viral compound, amantadine. A molecular model of this channel suggests that the imidazole side chains of His-37 from symmetry-related monomers of the homotetrameric pore converge to form a coordination site for transition metals. Thus, membrane currents of oocytes of Xenopus laevis expressing the M2 protein were recorded when the solution bathing the oocytes contained various transition metals. Membrane currents were strongly and reversibly inhibited by Cu2+ with biphasic reaction kinetics. The biphasic inhibition curves may be explained by a two-site model involving a fast-binding peripheral site with low specificity for divalent metal ions, as well as a high affinity site (Kdiss approximately 2 microM) that lies deep within the pore and shows rather slow-binding kinetics (kon = 18.6 +/- 0.9 M-1 s-1). The pH dependence of the interaction with the high affinity Cu2+-binding site parallels the pH dependence of inhibition by amantadine, which has previously been ascribed to protonation of His-37. The voltage dependence of the inhibition at the high affinity site indicates that the binding site lies within the transmembrane region of the pore. Furthermore, the inhibition by Cu2+ could be prevented by prior application of the reversible blocker of M2 channel activity, BL-1743, providing further support for the location of the site within the pore region of M2. Finally, substitutions of His-37 by alanine or glycine eliminated the high affinity site and resulted in membrane currents that were only partially inhibited at millimolar concentrations of Cu2+. Binding of Cu2+ to the high affinity site resulted in an approximately equal inhibition of both inward and outward currents. The wild-type protein showed very high specificity for Cu2+ and was only partially inhibited by 1 mM Ni2+, Pt2+, and Zn2+. These data are discussed in terms of the functional role of His-37 in the mechanism of proton translocation through the channel.  (+info)

Internal electron transfer between hemes and Cu(II) bound at cysteine beta93 promotes methemoglobin reduction by carbon monoxide. (2/7019)

Previous studies showed that CO/H2O oxidation provides electrons to drive the reduction of oxidized hemoglobin (metHb). We report here that Cu(II) addition accelerates the rate of metHb beta chain reduction by CO by a factor of about 1000. A mechanism whereby electron transfer occurs via an internal pathway coupling CO/H2O oxidation to Fe(III) and Cu(II) reduction is suggested by the observation that the copper-induced rate enhancement is inhibited by blocking Cys-beta93 with N-ethylmaleimide. Furthermore, this internal electron-transfer pathway is more readily established at low Cu(II) concentrations in Hb Deer Lodge (beta2His --> Arg) and other species lacking His-beta2 than in Hb A0. This difference is consistent with preferential binding of Cu(II) in Hb A0 to a high affinity site involving His-beta2, which is ineffective in promoting electron exchange between Cu(II) and the beta heme iron. Effective electron transfer is thus affected by Hb type but is not governed by the R left arrow over right arrow T conformational equilibrium. The beta hemes in Cu(II)-metHb are reduced under CO at rates close to those observed for cytochrome c oxidase, where heme and copper are present together in the oxygen-binding site and where internal electron transfer also occurs.  (+info)

Negligible amount of copper in hepatic L-tryptophan 2,3-dioxygenase. (3/7019)

During the purification of L-tryptophan 2,3-dioxygenase, a protohemoprotein from rat liver, both copper and heme contents of the preparations were found to be progressively increased as purification proceeded. However, the greater part of copper was removed in the late stages of the purification giving a copper to heme ratio less than 0.4. The small amounts of copper could further be reduced by one-half, by a mild treatment of enzyme with chelators such as ethylenedi aminetetraacetate, without any accompanying decrease in enzymatic activity. Since the turnover number of these enzyme preparations expressed per mol of enzyme-bound heme, 200 to 277 min-1 at 25 degrees, were either comparable to or slightly higher than those reported with homogeneous enzyme preparations, the heme in the preparation was considered to be of fully active L-tryptophan 2,3-dioxygenase and, therefore, such a small ratio of copper to heme, 0.1 to 0.3, indicated that copper is not a constituent of L-tryptophan 2,3-dioxygenase of rat liver. The findings were thus inconsistent with the results of Brady et al. (Brady, F. O., Monaco, M. E. Forman, H. J. Schutz, G., and Feigelson, P. (1972) J. Biol. Chem. 247, 7915-7922), who found that L-tryptophan 2,3-dioxygenase contained 2 g atoms of copper and 2 mol of heme/mol of enzyme. Possible reasons for this discrepancy have been discussed.  (+info)

Characterisation of copper-binding to the second sub-domain of the Menkes protein ATPase (MNKr2). (4/7019)

The Menkes ATPase (MNK) has an essential role in the translocation of copper across cellular membranes. In a complementary manner, the intracellular concentration of copper regulates the activity and cellular location of the ATPase through its six homologous amino-terminal domains. The roles of the six amino-terminal domains in the activation and cellular trafficking processes are unknown. Understanding the role of these domains relies on the development of an understanding of their metal-binding properties and structural properties. The second conserved sub-domain of MNK was over-expressed, purified and its copper-binding properties characterised. Reconstitution studies demonstrate that copper binds to MNKr2 as Cu(I) with a stoichiometry of one copper per domain. This is the first direct evidence of copper-binding to the MNK amino-terminal repeats. Circular dichroism studies suggest that the binding or loss of copper to MNKr2 does not cause substantial changes to the secondary structure of the protein.  (+info)

Computed radiography dual energy subtraction: performance evaluation when detecting low-contrast lung nodules in an anthropomorphic phantom. (5/7019)

A dedicated chest computed radiography (CR) system has an option of energy subtraction (ES) acquisition. Two imaging plates, rather than one, are separated by a copper filter to give a high-energy and low-energy image. This study compares the diagnostic accuracy of conventional computed radiography to that of ES obtained with two radiographic techniques. One soft tissue only image was obtained at the conventional CR technique (s = 254) and the second was obtained at twice the radiation exposure (s = 131) to reduce noise. An anthropomorphic phantom with superimposed low-contrast lung nodules was imaged 53 times for each radiographic technique. Fifteen images had no nodules; 38 images had a total of 90 nodules placed on the phantom. Three chest radiologists read the three sets of images in a receiver operating characteristic (ROC) study. Significant differences in Az were only found between (1) the higher exposure energy subtracted images and the conventional dose energy subtracted images (P = .095, 90% confidence), and (2) the conventional CR and the energy subtracted image obtained at the same technique (P = .024, 98% confidence). As a result of this study, energy subtracted images cannot be substituted for conventional CR images when detecting low-contrast nodules, even when twice the exposure is used to obtain them.  (+info)

Enhanced bioaccumulation of heavy metal ions by bacterial cells due to surface display of short metal binding peptides. (6/7019)

Metal binding peptides of sequences Gly-His-His-Pro-His-Gly (named HP) and Gly-Cys-Gly-Cys-Pro-Cys-Gly-Cys-Gly (named CP) were genetically engineered into LamB protein and expressed in Escherichia coli. The Cd2+-to-HP and Cd2+-to-CP stoichiometries of peptides were 1:1 and 3:1, respectively. Hybrid LamB proteins were found to be properly folded in the outer membrane of E. coli. Isolated cell envelopes of E. coli bearing newly added metal binding peptides showed an up to 1.8-fold increase in Cd2+ binding capacity. The bioaccumulation of Cd2+, Cu2+, and Zn2+ by E. coli was evaluated. Surface display of CP multiplied the ability of E. coli to bind Cd2+ from growth medium fourfold. Display of HP peptide did not contribute to an increase in the accumulation of Cu2+ and Zn2+. However, Cu2+ ceased contribution of HP for Cd2+ accumulation, probably due to the strong binding of Cu2+ to HP. Thus, considering the cooperation of cell structures with inserted peptides, the relative affinities of metal binding peptide and, for example, the cell wall to metal ion should be taken into account in the rational design of peptide sequences possessing specificity for a particular metal.  (+info)

The pro-phenoloxidase of coleopteran insect, Tenebrio molitor, larvae was activated during cell clump/cell adhesion of insect cellular defense reactions. (7/7019)

To characterize the proteins involved in cell clump/cell adhesion of insect cellular defense reactions, we induced the cell clump/cell adhesion reaction in vitro with the hemolymph of larvae of the coleopteran insect, Tenebrio molitor. The 72 kDa protein was specifically enriched in the residues of cell clump/cell adhesion and was purified to homogeneity. A cDNA clone for the 72 kDa protein was isolated. We found that the 72 kDa protein was an activated phenoloxidase from Tenebrio pro-phenoloxidase. We suggest that activated phenoloxidase is involved in the cell clump/cell adhesion reaction as well as in the synthesis of melanin.  (+info)

Cryptocyanin, a crustacean molting protein: evolutionary link with arthropod hemocyanins and insect hexamerins. (8/7019)

Cryptocyanin, a copper-free hexameric protein in crab (Cancer magister) hemolymph, has been characterized and the amino acid sequence has been deduced from its cDNA. It is markedly similar in sequence, size, and structure to hemocyanin, the copper-containing oxygen-transport protein found in many arthropods. Cryptocyanin does not bind oxygen, however, and lacks three of the six highly conserved copper-binding histidine residues of hemocyanin. Cryptocyanin has no phenoloxidase activity, although a phenoloxidase is present in the hemolymph. The concentration of cryptocyanin in the hemolymph is closely coordinated with the molt cycle and reaches levels higher than hemocyanin during premolt. Cryptocyanin resembles insect hexamerins in the lack of copper, molt cycle patterns of biosynthesis, and potential contributions to the new exoskeleton. Phylogenetic analysis of sequence similarities between cryptocyanin and other members of the hemocyanin gene family shows that cryptocyanin is closely associated with crustacean hemocyanins and suggests that cryptocyanin arose as a result of a hemocyanin gene duplication. The presence of both hemocyanin and cryptocyanin in one animal provides an example of how insect hexamerins might have evolved from hemocyanin. Our results suggest that multiple members of the hemocyanin gene family-hemocyanin, cryptocyanin, phenoloxidase, and hexamerins-may participate in two vital functions of molting animals, oxygen binding and molting. Cryptocyanin may provide important molecular data to further investigate evolutionary relationships among all molting animals.  (+info)

Levels of serum copper in 34 patients with adult non-Hodgkins lymphoma at different phases of the disease have been studied. All of the patients were evaluated with complete blood counts, sedimentation rate, gallium scintigraphy, liver and bone marrow biopsies, lymph node biopsy, and laparoscopy. The level of serum copper was significantly elevated in non-responding or relapsing patients (mean 191.06 micrograms/dl), and correlated with the estimated tumor burden. Serum copper levels within normal range were found in patients in complete remission (mean 114.76 micrograms/dl). Age- and sex-matched normal controls also showed serum copper levels within normal range (mean 112.81 micrograms/dl). It is proposed that serial measurements of serum copper level may be of use in: (1) monitoring the remission status of patients with non-Hodgkins lymphoma, (2) detecting early relapse of non-Hodgkins lymphoma, and (3) contrary to previous reports by Hrgovcic et al., the level of serum copper seems to be ...

Copper is an essential nutrient for sheep. Copper is required, but is also highly toxic. Copper is required for normal melanin production, elastin and collagen synthesis, iron metabolism, and the integrity of the nervous system. Copper is also known to be important for effective immune responses. The true importance of copper may be understood from looking at the problems associated with copper deficiency. Deficiencies are not often seen in the US. Common signs of copper deficiency are neonatal ataxia or swayback, degeneration of the myelin sheath of nerve fibers, and wool that lacks strength, crimp, elasticity, and pigment. Copper toxicity is more commonly seen and will prove to be more of a problem.. Copper Requirement. Copper is regularly used in the diet at about 8-11 parts per million. It may be toxic to sheep at 15-20 parts per million. There is a narrow difference between the amount of copper required and what will be toxic to the animal.

Crustaceans can store excess copper in the hepatopancreas, an organ playing a role in digestive activity as well as in neurosecretory control. Here, we studied the effect of copper exposure on the level of histamine, an indicator of food spoilage in edible crustaceans. Histamine is also a neuromodulator in the intestinal nervous system of crustaceans, and a human allergen. Marbled crayfish (Procambarus fallax forma virginalis) were exposed to average measured values of 0.031 mg Cu/l and 0.38 mg Cu/l, respectively, for 14 days and then transferred to copper-free water for another 14 days. Concentrations of copper and histamine in the hepatopancreas and muscle were evaluated at different time points. Histamine levels were significantly higher in hepatopancreas and muscle tissues at the highest exposure level, but only after transfer of the animals to copper-free water. The increased histamine concentration following copper exposure may be explained by a (delayed) stress response, and by up-regulated

Because of its role in facilitating iron uptake, copper deficiency can produceanemia-like symptoms, neutropenia, bone abnormalities, hypopigmentation, impaired growth, increased incidence of infections, osteoporosis, hyperthyroidism, and abnormalities in glucose and cholesterol metabolism. Conversely, Wilsons disease causes an accumulation of copper in body tissues. Severe deficiency can be found by testing for low plasma or serum copper levels, low ceruloplasmin, and low red blood cell superoxide dismutase levels; these are not sensitive to marginal copper status. The cytochrome c oxidase activity of leucocytes and platelets has been stated as another factor in deficiency, but the results have not been confirmed by replication.

In this paper we examine how the bacterial growth is influenced by the availability of copper ions in complex Mueller Hinton growth media. The data shows that the free copper concentration is seven to eight orders of magnitude lower the total copper concentration and that there seems to be a better correlation between the free copper concentration and bacterial growth, than for the total copper concentration and growth. Furthermore, it is shown that the initial pH influences the amount of free copper ions in the media and that this has a direct effect on the ability of bacterial cultures to grow. However, there still remains an effect of pH on bacterial growth which cannot be attributed to the influence of the Cu2+ concentration alone. The study also shows that the sterilization treatment can have some effect on the availability of copper ions in the media over time. Freshly autoclaved and sterile filtered media contain the same level of free copper ions and perform equally well in the ...

Copper solution. Copper is an essential trace element for our organism. It has a long medical pre-history as means of healing. It was already in use in Egypt 4000 years ago. For many ages the copper jewellery was worn because of its therapeutic impact. Besides wearing copper, many other treatments were known and applied including the use of copper powder. Hippocrates and Paracelsus used copper in their medical practice. Spiritual qualities: Copper intensifies the dream life. It develops the feeling for aesthetic and beauty. Copper helps relaxation, unblocks and fosters the intuition. Copper is vital for health. The acknowledged health claims concerning copper indicate that:. • Copper contributes to maintenance of connective tissues.. • Copper contributes to energy metabolism within the organism.. • Copper contributes to normal functioning of the nervous system.. • Copper contributes to normal hair pigmentation. • Copper contributes to distribution of iron in the organism.. • Copper ...
Wilson disease is a rare autosomal recessive inherited disorder of copper metabolism. The condition is characterized by excessive deposition of copper in the liver, brain, and other tissues.
Similar to iron, coppers unique ability to transfer electrons makes it a critical component for many metabolic pathways. Copper levels must be maintained within a narrow range for optimal function. We know that there are elevated levels of copper in the brain tissue in people with Alzheimers disease. Elevated copper levels also contribute to the retinal degeneration and cerebellar degeneration that leads to cognitive dysfunction. Elevated copper levels have been shown to lead to some cancers and heart disease. Elevated levels also inhibit Thyroid Releasing Hormone at the hypothalamus and in the case of Wilsons Syndrome, build up in the liver preventing conversion of T4 to the active thyroid hormone, T3. Common sources of copper exposure are copper piping, copper cooking utensils and supplements.. ...
Acute symptoms of copper poisoning by ingestion include vomiting, hematemesis (vomiting of blood), hypotension (low blood pressure), melena (black tarry feces), coma, jaundice (yellowish pigmentation of the skin), and gastrointestinal distress.[1] Individuals with glucose-6-phosphate deficiency may be at increased risk of hematologic effects of copper.[1] Hemolytic anemia resulting from the treatment of burns with copper compounds is infrequent.[1]. Chronic (long-term) effects of copper exposure can damage the liver and kidneys.[2] Mammals have efficient mechanisms to regulate copper stores such that they are generally protected from excess dietary copper levels.[2][3]. Those same protection mechanisms can cause milder symptoms, which are often misdiagnosed as psychiatric disorders. There is a lot of research going on regarding the function of the Cu/Zn ratio in many conditions, neurological, endocrinological and psychological.[4][5][6] The diagnostic difficulties arise from the fact that many ...

AU - Daston, George P.. AU - Kwik-Uribe, Catherine L.. AU - Rucker, Robert B.. PY - 1998. Y1 - 1998. N2 - Copper deficiency during embryonic and fetal development can result in numerous gross structural and biochemical abnormalities. Such a deficiency can arise through a variety of mechanisms, including low maternal dietary copper intake, disease-induced or drug-induced changes in maternal and conceptus copper metabolism, or both. These issues are discussed in this article along with the use of in vitro embryo culture models to study the mechanisms underlying copper deficiency-induced teratogenesis. Current data suggest that changes in free radical defense mechanisms, connective tissue metabolism, and energy production can all contribute to the dysmorphogenesis associated with developmental copper ...
Our work provides direct evidence that varying levels of copper can modulate the proliferation of cancer cells and associated tumor growth, indicating that copper can be a rate-limiting nutrient for tumors, much like oxygen and glucose. We do not think, however, that copper is a carcinogen: exposure of wild-type mice to 20 μM copper in drinking water for up to 2 y did not result in increased cancer incidence. We demonstrate herein that the activity of cytochrome c oxidase, a key enzyme in oxidative phosphorylation, in tumors is affected by copper levels. Additional bioavailable copper evidently facilitates increased production of ATP, which is consumed to fuel rapid proliferation of cancer cells. Thus, copper may not initiate transformation, but may stimulate proliferation of transformed cells by providing energy needed for cell-cycle progression.. In most eukaryotes, oxidative phosphorylation is the predominant source of ATP; glycolysis is used in an adaptive response to oxygen limitation. ...
TY - JOUR. T1 - Copper Depletion Down-regulates Expression of the Alzheimers Disease Amyloid-β Precursor Protein Gene. AU - Bellingham, Shayne A.. AU - Lahiri, Debomoy K.. AU - Maloney, Bryan. AU - La Fontaine, Sharon. AU - Multhaup, Gerd. AU - Camakaris, James. PY - 2004/5/7. Y1 - 2004/5/7. N2 - Alzheimers disease is characterized by the accumulation of amyloid-β peptide, which is cleaved from the amyloid-β precursor protein (APP). Reduction in levels of the potentially toxic amyloid-β has emerged as one of the most important therapeutic goals in Alzheimers disease. Key targets for this goal are factors that affect the regulation of the APP gene. Recent in vivo and in vitro studies have illustrated the importance of copper in Alzheimers disease neuropathogenesis and suggested a role for APP and amyloid-β in copper homeostasis. We hypothesized that metals and in particular copper might alter APP gene expression. To test the hypothesis, we utilized human fibroblasts overexpressing the ...
DESCRIPTION (provided by applicant): The overall aim of this grant is to elucidate the novel linkage between copper transport protein Antioxidant1 (Atox1) and NADPH oxidase involved in inflammatory angiogenesis. Ischemic disease is a leading cause of morbidity and mortality in worldwide. Neovascularization is an important repair process in response to ischemia, which depends on angiogenesis, inflammation and reactive oxygen species (ROS). Copper (Cu), an essential micronutrient, is involved in physiological repair processes such as wound healing and angiogenesis as well as in various pathophysiologies including tumor growth, atherosclerosis and inflammatory diseases. Since excess Cu is toxic, bioavailability of intracellular Cu is tightly controlled by Cu transport proteins such as Cu chaperone Atox1. Our laboratories provided the first evidence that Atox1 functions as a Cu-dependent transcription factor to regulate Cu-induced cell growth. Furthermore, we are one of the first to demonstrate that ...
CuD subjects In order to be enrolled into the CuD Arm, subjects who have had RYGB surgery will be recruited and screened for eligibility (inclusion and exclusion criteria below). Subjects whose plasma copper concentrations are in the deficient range (less than 80 μg/dL for women and less than 70 µg/dL for men, and/or ceruloplasmin activity below 62 units/L-1) following 4 weeks of supplementation with the RDA for copper will be eligible. Such supplementation is the routine standard of care with all patients undergoing RYGB surgery. This process aims to exclude patients who were only marginally copper deficient and not in need of sustained copper therapy. Subjects will be notified about their copper status by a study physician. They will be contacted by the study team, and their willingness to participate in the study will be determined.. Inclusion criteria: 1) Patient has a history of RYGB weight loss surgery; 2) subject has a plasma copper level which is less than 80 μg/dL for women andl less ...

Y1 - 2013. N2 - Ammonia oxidizing archaea (AOA) have recently been recognized as the primary nitrifiers in the marine environment; they thus play an important role in the nitrogen cycle. Available genome sequences of AOA indicate that numerous Cu-dependent enzymes are essential for both ammonia oxidation and electron transfer, suggesting a particularly high requirement for copper. However, our knowledge of the copper requirements of AOA and their response to copper limitation in the ocean is nonexistent. Here, we examine the copper requirements of the chemolithoautotrophic AOA Candidatus Nitrosopumilus maritimus SCM1 ...
TY - JOUR. T1 - Copper in fetal and neonatal development.. AU - Hurley, L. S.. AU - Keen, Carl L. AU - Lönnerdal, B.. PY - 1980. Y1 - 1980. N2 - The essentially of copper for normal fetal and neonatal development has been well documented, although copper metabolism during this period is poorly understood. The dietary requirement for copper is influenced by genetic background. The neurological phenotypic characteristics of the mutant gene quaking (qk) in mice resemble in part those of copper-deficient animals. Supplementation of the maternal diet with copper during pregnancy and lactation, or during lactation alone, greatly reduced the frequency of tremors characteristic of these mutants, and brought the otherwise low copper concentrations in the brain to normal. Prenatal copper supplementation of crinkled (cr) mice increased neonatal survival and produced nearly normal development of skin and hair. Non-supplemented cr/cr mice showed anaemia at 21 days of age which disappeared later. Similarly, ...
Pathogenic variants in the ATP7A gene result in several metabolic disorders (eg, Menkes disease) related to copper uptake and serum copper concentrations. Low copper concentration leads to progressive intellectual delay, bone and skeletal abnormalities, changes to skin and hair structure, hypotonia, and seizures. Symptoms of Menkes disease are progressive. Individuals are typically healthy from birth to 3-5 months, when the infant begins to lose developmental skills. Because of the wide spectrum of phenotypic severity and the progressive nature of symptoms, life expectancy is difficult to predict. Individuals diagnosed as children typically do not survive past early childhood, although some individuals respond to treatment with an improved quality of life and longer life expectancy. A diagnosis of Menkes disease is confirmed by genetic testing.. ...
The cop operon of Enterococcus hirae controls cytoplasmic copper levels. It encodes two copper ATPases, a repressor, and the CopZ metallo-chaperone. Transcription of these genes is induced by copper. However, at higher copper concentrations, CopZ is degraded by a copper-activated proteolytic activity. This specific proteolysis of CopZ can also be demonstrated in vitro with E. hirae extracts. Growth of the cells in copper increases the copper-inducible proteolytic activity in extracts. Zymography reveals the presence of a copper-dependent protease in crude cell lysates. Copper-stimulated proteolysis of CopZ appears to play an important role in copper homoeostasis by E. hirae. ...
Copper is an essential trace element required for many vitally important functions in all cell types in most living organisms [1]. Safe copper cellular uptake, its distribution to cuproenzyme formation sites and its excretion are provided by special copper metabolic system. Unidrectional transport of copper atoms to the sites of cuproenzyme formation is provided by proteins of this system consecutively through direct protein-protein interactions. Copper translocation through cell membrane is the crucial stage of copper metabolism. High affinity Cu(I) transporter, belonging to CTR1 family (encoded by SLC31A1), is the main candidate for mammalian transmembrane Cu(I) importer [2]. Despite the current progress in CTR1 structure and function studies many aspects of putative CTR1 mediated mechanisms remain to be unclear. It is still unknown, what protein is the donor of copper for N-terminal domain of CTR1, localized on the cell surface. The copper atoms could be provided by ceruloplasmin (Cp) - a ...
Predicting copper (Cu) toxicity in marine and estuarine environments is challenging because of the influence of anions on Cu speciation, competition between Cu2+ and other cations at the biotic ligand and the effect of salinity on the physiology of the organism. In the present study the combined effect of salinity and dissolved organic carbon (DOC) on Cu toxicity to larvae of Mytilus galloprovincialis was assessed. Two statistical models were developed and used to elucidate the relationship between Cu toxicity, salinity, and DOC. All models based on dissolved Cu indicate a decrease in Cu toxicity with increasing DOC concentrations, which can partly be explained by complexation of Cu2+ ions with DOC. These models also indicate an increase in Cu toxicity (modeled with dissolved Cu or Cu2+ activity) with increasing salinity, suggesting a salinity-induced alteration in the physiology of the mussel larvae. When based on Cu body burdens, neither of the models indicates an effect of salinity or DOC. ...
TY - JOUR. T1 - Regulation of the high-affinity copper transporter (hCtr1) expression by cisplatin and heavy metals. AU - Liang, Zheng Dong. AU - Long, Yan. AU - Chen, Helen H W. AU - Savaraj, Niramol. AU - Kuo, Macus Tien. PY - 2014/1/14. Y1 - 2014/1/14. N2 - Platinum-based antitumor agents have been the mainstay in cancer chemotherapy for many human malignancies. Drug resistance is an important obstacle to achieving the maximal therapeutic efficacy of these drugs. Understanding how platinum drugs enter cells is of great importance in improving therapeutic efficacy. It has been demonstrated that human high-affinity copper transporter 1 (hCtr1) is involved in transporting cisplatin into cells to elicit cytotoxic effects, although other mechanisms may exist. In this communication, we demonstrate that cisplatin transcriptionally induces the expression of hCtr1 in time- and concentration-dependent manners. Cisplatin functions as a competitor for hCtr1-mediated copper transport, resulting in reduced ...
Copper toxicity is rare in the general population. Excess copper consumption may lead to liver, kidney, or neurologic damage. Excess dosing may lead to toxic symptoms including weakness, abdominal pain, nausea, vomiting, and diarrhea, with more serious signs of acute toxicity including liver damage, kidney failure, pleural damage, coma, and death. Other medical problems associated with copper toxicity in studies or anecdotally include anxiety, depression, dizziness, fatigue, headache, learning disabilities, memory lapses, diminished concentration, insomnia, seizure, delirium, stuttering, hyperactivity, arthralgias, myalgias, hypertension, gingivitis, dermatitis, discoloration of skin/hair, preeclampsia, postpartum psychosis, weight gain, or transaminitis. Acute copper poisoning has occurred through the contamination of beverages by storage in copper containing containers as well as from contaminated water supplies. In the U.S., the health-based guideline for a maximum water copper concentration ...
At S & D Non-Ferrous, we stock Sulphur Copper in Grade CW114C, a free machining copper with an approximately 80% machinability rating. Adding sulphur to copper produces a free machining copper as the sulphur acts as a chip breaker, making it far easier to machine than pure copper and only having a minor effect on the conductivity of the metal.. Machining speeds can reach up to 4 times faster than those of pure copper and greater tooling life span is also seen when using sulphur copper over pure copper. Sulphur Copper is a versatile metal as it combines the high thermal and electrical conductivity values that are usually only seen in pure copper, however the ease of machining from the sulphur, allowing it to be used in a greater number of circumstances. Other qualities of CW114C are easy solder ability and decent levels of corrosion resistance. Our CW114C sulphur copper is readily available in a number of formations, including sulphur copper plate or sulphur copper bar in a range of shapes. Our ...
PROJECT: Wilsons disease (WD) is an inherited disorder of copper metabolism characterised by juvenile liver cirrhosis and by neurological symptoms. Copper levels in brain in WD have been reported to be 10 to 15 fold normal values, depending on the different brain regions. Being very few data on copper distribution in central nervous system in WD available, it seemed of interest to study the concentration of copper and of other trace elements (Zn, P, Mg, Ca, Fe and S) in the brain of a patient died for WD. PROCEDURE: a 56 year old woman affected by WD was admitted to our hospital with signs of hepatic failure and died few days later. At autopsy, a brain slice extending from the left to the right hemisphere was divided in 28 samples. On each sample Copper, Iron, Magnesium, Phosphorus, Sulphur, Zinc and Calcium were determined by Induced Coupled Plasma Atomic Emission Spectroscopy. RESULTS: the mean concentration of copper, ranging from 88 to 158 microg/g of dry tissue in all the brain specimens ...

Lapidaries (rock and gem polishers) have at times been sickened by absorption of copper while polishing malachite gemstones or carvings. It is possible that such absorption could occur in other instances where copper dissolved in a solvent or oil comes in regular contact with the skin. Swimming in lakes that have been treated with copper-bearing algicides, or that receive effluent from copper-treated cooling towers can also result in dermal absorption. Airborne copper sources can include fumes from smelting operations, or dust from any of the many processes involving copper and its compounds. Chronic exposure to copper dust can irritate the nose, mouth, and eyes, and cause headaches, dizziness, nausea, and diarrhea. The Occupational Safety and Health Administration (OSHA) has set a limit of 0.1 mg/m3 of copper fumes (vapor generated from heating copper) and 1 mg/m3 of copper dusts (fine metallic copper particles) and mists (aerosol of soluble copper) in workroom air during an 8-hour work shift, ...

birth defects. Exceeding the daily requirement is dangerous, however, because copper toxicity commonly occurs. Copper toxicity is a very serious medical problem. Acute toxicity due to ingestion of too much supplement, for example, may cause nausea, vomiting, abdominal pain, diarrhea, dizziness, headache, and a metallic taste in the mouth. Chronic toxicity is often caused by genetic defects of copper metabolism, such as Wilsons disease. In this disease, copper is not eliminated properly and is allowed to accumulate to toxic levels. Copper is therefore present at high concentration where it should not be, such as in the liver, the lens of the eye, kidneys, or brain.. Disease Prevention. Copper is a good antioxidant. It works together with an antioxidant enzyme, superoxide dismutase (SOD), to protect cell membranes from being destroyed by free radicals. Free radicals are any molecules that are missing one electron. Because this is an unbalanced and unstable state, a radical is desperately finding ...
Coppers most important alloy is bronze which gave its name to an historic age. Bronze forms by mixing copper with tin. The Bronze Age is typically dated to Sumer around 4000 BC. The Bronze Age lasted until the Iron Age which began around 2000 BC. However, the art of smelting and creating works in copper and bronze continues to the present day. Ancient copper and bronze works survive today as artifacts in museums and attest to the importance that the ancients placed on these metals. Many copper artifacts and tiles boast a green patina. This outer layer forms on copper due to oxidation; however, it actually protects the copper beneath it.. Copper and bronze were used to create jewelry as well as vessels for daily and ceremonial use. It was vital for trade as well as to centers that boasted large populations. Copper was often used to create purely functional items. For instance, one of the ancient pyramids features copper piping. Copper has historically been used on various exterior buildings; ...
How copper is made - material, used, processing, steps,Once the waste materials have been physically removed from the ore, the remaining copper concentrate must undergo several chemical reactions to remove the iron and sulfur. This process is called smelting and traditionally involves two furnaces as described below..Extracting copper. Extracting copper.,Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell.

Copper in blood and liver can be divided into several fractions. Copper in blood is about evenly divided between erythrocytes and plasma. Normal concentrations for most species range between one and two parts per million. Plasma copper is mainly a copper protein, ceruloplasmin and a loosely bound form, reacting directly with Na diethyldithiocarbamate (DR Cu). In livers of normal rats (ca. 18 ppm Cu) the distribution is: debris, 12.8%; mitochondria, 13.5%; microsomes, 17.9%; and soluble fraction, 54.8%. On the other hand, in cattle with higher liver copper levels (ca. 69.5 ppm) the distribution is: debris, 22.2%; mitochondria, 12.3%; microsomes, 14.6%; and soluble fraction, 50.9%. The distributions are influenced by dietary copper in rats fed rations containing from 1 ppm to 200 ppm Cu. Erythrocyte and DR Cu appeared to be directly related to the copper intake, with values ranging from 0.95 to 2.04 μg/ml and 0.19 to 1.52 μg respectively. Ceruloplasmin values were depressed in the low ration ...
Additionally, we only ended up reacting 74.0% of the copper that shouldve theoretically reacted. This low percentage and low mass of reacted copper, are due to a number of inherent flaws in our experiment, and ended up skewing the molar ratio of reacted copper to precipitate silver. As previously mentioned, when it came time to take the remaining copper ribbon out of the silver nitrate solution, no matter how hard we scrapped, there still was a good amount of silver coating the copper (not to mention the silver that continued to form). Additionally, after we dried the copper, we noticed that the copper had a greenish coating on it, signifying that the copper was most likely oxidized. Both the oxidation of the copper, coupled with the amount of silver that was still stuck on the ribbon ended up increasing the mass of the recovered copper. In the end, this meant that we were subtracting a larger number from the initial mass of copper, and ended up getting a smaller number of moles of reacted ...

We developed a procedure for aqueous ion exchange to obtain different Cu loadings of Cu/SAPO-34 (between 0 and 2.6 wt %). The catalysts were washcoated on monoliths and characterised with respect to their activity and selectivity under standard selective catalytic reduction (SCR), fast SCR, NH3 oxidation and NO oxidation reactions. They were further characterised using X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), H-2-temperature programmed reduction (H-2-TPR), ultraviolet (UV)-vis spectroscopy and NH3 adsorption. As expected, activity of all reactions increased with copper loading, due to increased number of active sites. However, the N2O formation during standard and fast SCR yielded interesting mechanistic information. We observed that N2O formation at low temperature increased with copper loading for the standard SCR reaction, while it decreased for fast SCR. The low-temperature N2O formation during fast SCR thus occurs predominantly over Bronsted sites. Species responsible for N2O
Disclosed is a dispersion comprising at least metallic copper particles with gelatin provided on the surface thereof, a polymeric dispersant, and an organic solvent. The dispersion is produced by reducing copper oxide in an aqueous solvent in the presence of gelatin having an amine number and an acid number such that the difference therebetween (amine number−acid number) is 0 or less, then subjecting the reaction solution to solid-liquid separation, and then mixing the resultant metallic copper particles with gelatin provided on the surface thereof and a polymeric dispersant having an amine number and an acid number such that the difference therebetween (amine number−acid number) is 0 to 50, into an organic solvent. The dispersion can maintain dispersion stability of the metallic copper particles for a long period of time, is suitable for inkjet printing and spray coating and can be used in the formation of microelectrodes and circuit wiring patterns, for example, in printed wiring boards, and
Plasma copper concentration. The breed- and pooled-plasma Cu concentrations are shown in Figure 1 and Table 1 respectively. In both breeds, gestation or parturition had no significant effect on plasma Cu concentration, except for a high concentration at the beginning of the third trimester. When the samples from both breeds were pooled, the plasma concentration was significantly (p , 0.05) higher at 7-mo compared to several other time points. By 8-mo of pregnancy, the concentration declined to early pregnancy concentrations and remained so until parturition. At 0.25-mo (one week) following parturition, plasma Cu concentration increased compared to the concentration at full term. Then it gradually declined to reach a concentration similar to that prior to conception and early pregnancy. During the experiment, Angus tended to have a higher plasma Cu concentration compared to Simmental.. Plasma zinc concentration. The overall mean plasma Zn concentration between the breeds during the experiment was ...
The objectives of this research project are to: (1) measure how quickly a population of Pseudomonas syringae, a casual agent of bacterial blight of many woody plants, can become tolerant to copper under standard disease control programs; and (2) study the population dynamics of tolerant versus sensitive individuals in the presence and absence of copper sprays. Copper tolerant strains of P. syringae have been isolated from Northwest nurseries and fruit orchards. Growers have relied heavily on fixed copper compounds as bactericides, but because of copper tolerance, these products are no longer providing acceptable levels of disease control. A survey has shown that there are high levels of copper tolerance in populations of pathogenic P. syringae. Research has focused on understanding tolerance mechanisms at the molecular level, describing localized toxic effects in detail, but it has not addressed ecological aspects of microbial systems at the population level. This has hindered the extrapolation ...

... s, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior. Their activity is regulated by factors that control their ability to bind to and hydrolyze guanosine triphosphate (GTP) to guanosine diphosphate (GDP). When they are bound to GTP, they are 'on', and, when they are bound to GDP, they are 'off'. G proteins belong to the larger group of enzymes called GTPases.. There are two classes of G proteins. The first function as monomeric small GTPases, while the second function as heterotrimeric G protein complexes. The latter class of complexes is made up of alpha (α), beta (β) and gamma (γ) subunits.[1] In addition, the beta and gamma subunits can form a stable dimeric complex referred to as the beta-gamma complex.. G proteins located within the cell are activated by G protein-coupled receptors (GPCRs) that span the cell ...

Although they are grown as ornamental trees in many areas of the Old World tropics of Indonesia, Malaysia and the Philippines, only the Philippines produces and processes pili nuts commercially. Production centers are located in the Bicol region, provinces of Sorsogon, Albay, and Camarines Sur, southern Tagalog, and eastern Visayas. There is no commercial planting of this crop; fruits are collected from natural stands in the mountains near these provinces. In 1977, the Philippines exported approximately 3.8 t of pili preparation to Guam and Australia. The most important product from pili is the kernel. When raw, its flavor resembles that of roasted pumpkin seed, and when roasted, its nutty flavor and waxy texture is similar to the pine nut. Research from the Institute of Plant Breeding, University of the Philippines at Los Banos describe pili nuts of high quality as large, round kernel, and a thin pulp and shell.
