Ionic currents underlying spontaneous action potentials in isolated cerebellar Purkinje neurons. (1/2206)

Acutely dissociated cell bodies of mouse Purkinje neurons spontaneously fired action potentials at approximately 50 Hz (25 degrees C). To directly measure the ionic currents underlying spontaneous activity, we voltage-clamped the cells using prerecorded spontaneous action potentials (spike trains) as voltage commands and used ionic substitution and selective blockers to isolate individual currents. The largest current flowing during the interspike interval was tetrodotoxin-sensitive sodium current (approximately -50 pA between -65 and -60 mV). Although the neurons had large voltage-dependent calcium currents, the net current blocked by cobalt substitution for calcium was outward at all times during spike trains. Thus, the electrical effect of calcium current is apparently dominated by rapidly activated calcium-dependent potassium currents. Under current clamp, all cells continued firing spontaneously (though approximately 30% more slowly) after block of T-type calcium current by mibefradil, and most cells continued to fire after block of all calcium current by cobalt substitution. Although the neurons possessed hyperpolarization-activated cation current (Ih), little current flowed during spike trains, and block by 1 mM cesium had no effect on firing frequency. The outward potassium currents underlying the repolarization of the spikes were completely blocked by 1 mM TEA. These currents deactivated quickly (<1 msec) after each spike. We conclude that the spontaneous firing of Purkinje neuron cell bodies depends mainly on tetrodotoxin-sensitive sodium current flowing between spikes. The high firing rate is promoted by large potassium currents that repolarize the cell rapidly and deactivate quickly, thus preventing strong hyperpolarization and restoring a high input resistance for subsequent depolarization.  (+info)

Cyanide poisoning: pathophysiology and treatment recommendations. (2/2206)

This paper aims to assess and compare currently available antidotes for cyanide poisoning. Such evaluation, however, is difficult. Thus, extrapolation from the results of animal studies has potential pitfalls, as significant inter-species differences in response may exist, and these experiments often involve administration of toxin and antidote almost simultaneously, rather than incorporating a more realistic time delay before initiation of treatment. Direct inference from human case reports is also problematic; either because of uncertainties over the exposure levels involved (and hence the likely outcome without treatment), or because of difficulties in identifying the specific contribution of a particular antidote within the overall treatment regimen. Certainly an effort to compare the relative efficacy of cyanide antidotes produces equivocal findings, with no single regimen clearly standing out. Indeed, factors such as the risks of antidote toxicity to various individuals and other practical issues, may be more important considerations. There is therefore no single treatment regimen which is best for all situations. Besides individual risk factors for antidote toxicity, the nature of the exposure and hence its likely severity, the evolving clinical features and the number of persons involved and their proximity to hospital facilities, all need to be considered. Clinically mild poisoning may be treated by rest, oxygen and amyl nitrite. Intravenous antidotes are indicated for moderate poisoning. Where the diagnosis is uncertain, sodium thiosulphate may be the first choice. With severe poisoning, an additional agent is required. Given the various risks with methaemoglobin formers or with unselective use of kelocyanor, hydroxocobalamin may be preferred from a purely risk-benefit perspective. However the former alternatives will likely remain important.  (+info)

Source of inappropriate receptive fields in cortical somatotopic maps from rats that sustained neonatal forelimb removal. (3/2206)

Previously this laboratory demonstrated that forelimb removal at birth in rats results in the invasion of the cuneate nucleus by sciatic nerve axons and the development of cuneothalamic cells with receptive fields that include both the forelimb-stump and the hindlimb. However, unit-cluster recordings from primary somatosensory cortex (SI) of these animals revealed few sites in the forelimb-stump representation where responses to hindlimb stimulation also could be recorded. Recently we reported that hindlimb inputs to the SI forelimb-stump representation are suppressed functionally in neonatally amputated rats and that GABAergic inhibition is involved in this process. The present study was undertaken to assess the role that intracortical projections from the SI hindlimb representation may play in the functional reorganization of the SI forelimb-stump field in these animals. The SI forelimb-stump representation was mapped during gamma-aminobutyric acid (GABA)-receptor blockade, both before and after electrolytic destruction of the SI hindlimb representation. Analysis of eight amputated rats showed that 75.8% of 264 stump recording sites possessed hindlimb receptive fields before destruction of the SI hindlimb. After the lesions, significantly fewer sites (13.2% of 197) were responsive to hindlimb stimulation (P < 0.0001). Electrolytic destruction of the SI lower-jaw representation in four additional control rats with neonatal forelimb amputation did not significantly reduce the percentage of hindlimb-responsive sites in the SI stump field during GABA-receptor blockade (P = 0.98). Similar results were obtained from three manipulated rats in which the SI hindlimb representation was silenced temporarily with a local cobalt chloride injection. Analysis of response latencies to sciatic nerve stimulation in the hindlimb and forelimb-stump representations suggested that the intracortical pathway(s) mediating the hindlimb responses in the forelimb-stump field may be polysynaptic. The mean latency to sciatic nerve stimulation at responsive sites in the GABA-receptor blocked SI stump representation of neonatally amputated rats was significantly longer than that for recording sites in the hindlimb representation [26.3 +/- 8.1 (SD) ms vs. 10.8 +/- 2.4 ms, respectively, P < 0.0001]. These results suggest that hindlimb input to the SI forelimb-stump representation detected in GABA-blocked cortices of neonatally forelimb amputated rats originates primarily from the SI hindlimb representation.  (+info)

Regulation of interleukin-8 expression by reduced oxygen pressure in human glioblastoma. (4/2206)

Oxygen deprivation is an important biological feature of tumor growth. We previously showed that in glioma, anoxia increases expression of IL-8, a chemokine and angiogenic factor. Here, we analysed for the first time the biochemical mechanisms inducing the IL-8 gene upon anoxia in glioma cells, and showed that they differ from those inducing the VEGF gene. Both genes are induced in biologically and genetically heterogenous glioblastoma cell lines (LN-229, LN-Z308, U87MG, T98G), whereas, in gliosarcoma cells (D247MG), only the VEGF gene is induced. The kinetics of IL-8 and VEGF mRNA inductions differ in these cells and reoxygenation experiments showed that the induction is due to the anoxic stress per se. Furthermore, in LN-229 and LN-Z308 cell lines actinomycin D, DRB and nuclear run-on experiments showed that anoxia stimulates increased transcription of both genes. Electromobility shift assays show increased protein binding to the AP-1 site on the IL-8 promoter following anoxia treatment. Finally, in situ hybridization on glioblastoma sections shows that the in vivo expression patterns of IL-8 and VEGF genes overlap, but are not identical. Since intratumoral augmentation of IL-8 and VEGF secretion, following microenvironmental decreases in oxygen pressure, may promote angiogenesis, further definition of these pathways is essential to appropriately target them for antitumoral therapy.  (+info)

Acetylcholine-induced membrane potential changes in endothelial cells of rabbit aortic valve. (5/2206)

1. Using a microelectrode technique, acetylcholine (ACh)-induced membrane potential changes were characterized using various types of inhibitors of K+ and Cl- channels in rabbit aortic valve endothelial cells (RAVEC). 2. ACh produced transient then sustained membrane hyperpolarizations. Withdrawal of ACh evoked a transient depolarization. 3. High K+ blocked and low K+ potentiated the two ACh-induced hyperpolarizations. Charybdotoxin (ChTX) attenuated the ACh-induced transient and sustained hyperpolarizations; apamin inhibited only the sustained hyperpolarization. In the combined presence of ChTX and apamin, ACh produced a depolarization. 4. In Ca2+-free solution or in the presence of Co2+ or Ni2+, ACh produced a transient hyperpolarization followed by a depolarization. In BAPTA-AM-treated cells, ACh produced only a depolarization. 5. A low concentration of A23187 attenuated the ACh-induced transient, but not the sustained, hyperpolarization. In the presence of cyclopiazonic acid, the hyperpolarization induced by ACh was maintained after ACh removal; this maintained hyperpolarization was blocked by Co2+. 6. Both NPPB and hypertonic solution inhibited the membrane depolarization seen after ACh washout. Bumetanide also attenuated this depolarization. 7. It is concluded that in RAVEC, ACh produces a two-component hyperpolarization followed by a depolarization. It is suggested that ACh-induced Ca2+ release from the storage sites causes a transient hyperpolarization due to activation of ChTX-sensitive K+ channels and that ACh-activated Ca2+ influx causes a sustained hyperpolarization by activating both ChTX- and apamin-sensitive K+ channels. Both volume-sensitive Cl- channels and the Na+-K+-Cl- cotransporter probably contribute to the ACh-induced depolarization.  (+info)

The distribution of neurons expressing calcium-permeable AMPA receptors in the superficial laminae of the spinal cord dorsal horn. (6/2206)

The superficial dorsal horn is a major site of termination of nociceptive primary afferents. Fast excitatory synaptic transmission in this region is mediated mainly by release of glutamate onto postsynaptic AMPA and NMDA receptors. NMDA receptors are known to be Ca2+-permeable and to provide synaptically localized Ca2+ signals that mediate short-term and long-term changes in synaptic strength. Less well known is a subpopulation of AMPA receptors that is Ca2+-permeable and has been shown to be synaptically localized on dorsal horn neurons in culture (Gu et al., 1996) and expressed by dorsal horn neurons in situ (Nagy et al., 1994; Engelman et al., 1997). We used kainate-induced cobalt uptake as a functional marker of neurons expressing Ca2+-permeable AMPA receptors and combined this with markers of nociceptive primary afferents in the postnatal rat dorsal horn. We have shown that cobalt-positive neurons are located in lamina I and outer lamina II, a region strongly innervated by nociceptors. These cobalt-positive neurons colocalize with afferents labeled by LD2, and with the most dorsal region of capsaicin-sensitive and IB4- and LA4-positive afferents. In contrast, inner lamina II has a sparser distribution of cobalt-positive neurons. Some lamina I neurons expressing the NK1 receptor, the receptor for substance P, are also cobalt positive. These neurons are likely to be projection neurons in the nociceptive pathway. On the basis of all of these observations, we propose that Ca2+-permeable AMPA receptors are localized to mediate transmission of nociceptive information.  (+info)

EPR characterization of axial bond in metal center of native and cobalt-substituted guanylate cyclase. (7/2206)

The nature of the metal-proximal base bond of soluble guanylate cyclase from bovine lung was examined by EPR spectroscopy. When the ferrous enzyme was mixed with NO, a new species was transiently produced and rapidly converted to a five-coordinate ferrous NO complex. The new species exhibited the EPR signal of six-coordinate ferrous NO complex with a feature of histidine-ligated heme. The histidine ligation was further examined by using the cobalt protoporphyrin IX-substituted enzyme. The Co2+-substituted enzyme exhibited EPR signals of a broad g perpendicular;1 component and a g;1 component with a poorly resolved triplet of 14N superhyperfine splittings, which was indicative of the histidine ligation. These EPR features were analogous to those of alpha-subunits of Co2+-hemoglobin in tense state, showing a tension on the iron-histidine bond of the enzyme. The binding of NO to the Co2+-enzyme markedly stimulated the cGMP production by forming the five-coordinate NO complex. We found that N3- elicited the activation of the ferric enzyme by yielding five-coordinate high spin N3- heme. These results indicated that the activation of the enzymes was initiated by NO binding to the metals and proceeded via breaking of the metal-histidine bonds, and suggested that the iron-histidine bond in the ferric enzyme heme was broken by N3- binding.  (+info)

Inhibition of hypoxia-inducible factor 1 activation by carbon monoxide and nitric oxide. Implications for oxygen sensing and signaling. (8/2206)

It has been proposed that cells sense hypoxia by a heme protein, which transmits a signal that activates the heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1), thereby inducing a number of physiologically relevant genes such as erythropoietin (Epo). We have investigated the mechanism by which two heme-binding ligands, carbon monoxide and nitric oxide, affect oxygen sensing and signaling. Two concentrations of CO (10 and 80%) suppressed the activation of HIF-1 and induction of Epo mRNA by hypoxia in a dose-dependent manner. In contrast, CO had no effect on the induction of HIF-1 activity and Epo expression by either cobalt chloride or the iron chelator desferrioxamine. The affinity of CO for the putative sensor was much lower than that of oxygen (Haldane coefficient, approximately 0.5). Parallel experiments were done with 100 microM sodium nitroprusside, a nitric oxide donor. Both NO and CO inhibited HIF-1 DNA binding by abrogating hypoxia-induced accumulation of HIF-1alpha protein. Moreover, both NO and CO specifically targeted the internal oxygen-dependent degradation domain of HIF-1alpha, and also repressed the C-terminal transactivation domain of HIF-1alpha. Thus, NO and CO act proximally, presumably as heme ligands binding to the oxygen sensor, whereas desferrioxamine and perhaps cobalt appear to act at a site downstream.  (+info)

AU - Sierra, Rafael J.. AU - Moyer, Thomas P.. PY - 2015/2/1. Y1 - 2015/2/1. N2 - Objectives: Cobalt (Co) exposure has been documented to result in increased erythropoiesis. To evaluate the potential for implant-derived Co toxicity, we examined the relationship between serum Co (sCo) and erythrocyte counts (ERY) in a metal-containing total-hip arthroplasty implant population. Methods: Retrospective review of sCo concentrations identified 77 patients with concomitant ERY. Statistical analysis was performed to determine if there was a significant difference in ERY for patients divided into clinically relevant sCo ranges. A single detailed case review of a patient with a loose mal-positioned acetabular component and significantly elevated sCo was also performed for symptoms thought to arise from Co ...
In this diploma thesis the adsorption of cobalt ions on egg shells was studied depending on the different initial concentrations of cobalt ions solutions (4.488 mmol dm-3, 8.365 mmol dm-3, 11.427 mmol dm-3, 20.814 mmol dm-3, and 31.223 mmol dm-3) at a constant temperature of 28°C, stirring speed of 200 rpm for 96 h. Egg shells with diameter d , 125 m were used as adsorbent while the concentrations of cobalt ions in equilibrium solutions were determined spectrophotometrically. Based on the results obtained, it can be concluded that the amount of adsorbed cobalt ions (qe) increases with the increase of the equilibrium concentration of cobalt ions in solution (ce) reaching value of qe = 0.163 mmol g-1 that represents the equilibrium amount of adsorbed cobalt ions on egg shells. The adsorption efficiency of cobalt ions reaches its maximum value of 9.758 % at initial concentration of 8.365 mmol dm-3 and then decreases with the increase of initial concentration of cobalt ions in solution.

Cyclic and square wave voltammetric measurements have been performed to assess their redox characteristics. Both complexes undergo several reduction processes in cathodic negative potential region at more or less similar potentials. In view of these reductions being independent of the nature of the metal, they are thought to be ligand-localized. Although similar in negative region, a marked difference in the behavior of the complexes is ...

Building on the idea of a pentapyridine ligand, the Piers group has recently focused on the development of a family of boron-substituted pentadentate ligands (B2Pz4Py). This work will describe the expansion of preliminary research completed by Dr. Denis Spasyuk, involving newly synthesized cobalt complexes coordinated with a dianionic pentadentate phenyl-substituted diborate ligand. Instead of continuing with the phenyl-substituted ligand, the synthetic procedure for the ligand was adapted to make a tolyl-substituted version. The synthesis and characterization of cobalt(II) complexes and their propensity to bind O2 forming a binuclear μ-peroxo cobalt(III) complex was explored. The binding of oxygen was found to be reversible and that the O2 was activated towards protonation and that reduction of the products lead back to cobalt(II). The relevance of this chemistry to the Oxygen Reduction Reaction (ORR) was discussed. The catalytic ability of the complex to reduce oxygen was measured and ...
Workers may be exposed to cobalt during the production of cobalt and cobalt salts, in the production of alloys and hard metal, drying agents, pigments and catalysts, and during diamond polishing. World production of refined cobalt has increased steadily over the last decade, due partly to new operations and partly to a net increase in production by established producers [1]. World cobalt mine production in 2001 was 36,700 tons and the cobalt refinery production 38,400 tons [2]. The respective numbers in 2016 were 123,000 tons and 91,300 tons [3]. In the United States, more than a million workers are potentially exposed to cobalt and its compounds [4]. In Finland, about 1500 workers (0.1% of employed people) are estimated to be exposed to cobalt or cobalt compounds at work [5].. Different epidemiological studies provide relatively sparse and contradictory data on the carcinogenicity of cobalt to humans. A Swedish study retrospectively followed a cohort of 3000 cobalt workers in 1951-1982 [6]. It ...

In this study, N,N-dimethylaminopropyl methacrylamide (DMAPMAm) homopolymer and DMAPMAm/itaconic acid (DMAPMAm/IA) copolymers were obtained from 60Co-γ radiation polymerization. Gel fraction and percentage of swelling values were calculated through gravimetrical calculations. In order to increase the swelling of the hydrogel, the amount of IA in initial copolymer composition was gradually increased, but it was observed that gelation values were low. The structural and morphological assessments of homopolymer and copolymers were made by means of several techniques including Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Energy-Dispersive X-ray Spectroscopy (EDS). The cobalt ion (Co2+) removal capacities of hydrogel were investigated by taking into account of the initial metal ion concentration and pH of aqueous medium. When it came to the maximum capacity of values obtained from adsorption experiments by using Co2+ solutions at pH 5, they changed between ...
In order to collect further evidence on the mode of action for cobalt-induced carcinogenicity (see chapter Summary and discussion of carcinogenicity or the endpoint summary in IUCLID section 7.7- Carcinogenicity), further in vitro mechanistic studies were conducted. The aim of these studies was to elucidate the role of genotoxicity, oxidative stress and HIF1a activation, which are recognised key events in cells and tissues after cobalt exposure. In the ToxTracker assay reported by Derr and Brandsma (2019 and Hendriks (2019) mouse embryonic stem (mES) reporter cell lines were exposed to 15 different cobalt substances. The ToxTracker assay is used to identify the biological reactivity and potential carcinogenic properties of these cobalt substances in a single test. The test system monitors activation of specific cellular signalling pathways for detection of the biological reactivity of the cobalt substances. ToxTracker consists of a panel of six different mES GFP reporter cell lines ...
The predicted dominance of electric vehicles and the need for grid-scale energy storage have heightened concerns that cobalt, a key constituent of lithium-ion batteries, could become a critical limiting factor. With limited terrestrial resources and over half the global production coming from politically challenging regions increasing risk, a shortage of cobalt could be experienced by the early 2020s. Fortunately, the oceans contain about 70 times more cobalt than on land and can be harvested sustainably with passive adsorption technologies; and a symbiotic system using existing offshore structures to harvest cobalt could enhance the economic feasibility of seawater cobalt harvesting. Our study finds that retrofitting just 76 unused oil platforms in the Gulf of Mexico could extract an average of 27.3% of the nations 2017 cobalt consumption. New Offshore Opportunity for Underwater Cobalt Harvesting has the potential to reduce the cobalt supply pinch point in lithium-ion battery production ...

Our previous study demonstrated the direct involvement of the HIF-1α subunit in the promotion of cardiac differentiation of murine embryonic stem cells (ESCs). We report the use of cobalt chloride to induce HIF-1α stabilization in human ESCs to promote cardiac differentiation. Treatment of undifferentiated hES2 human ESCs with 50μM cobalt chloride markedly increased protein levels of the HIF-1α subunit, and was associated with increased expression of early cardiac specific transcription factors and cardiotrophic factors including NK2.5, vascular endothelial growth factor, and cardiotrophin-1. When pretreated cells were subjected to cardiac differentiation, a notable increase in the occurrence of beating embryoid bodies and sarcomeric actinin-positive cells was observed, along with increased expression of the cardiac-specific markers, MHC-A, MHC-B, and MLC2V. Electrophysiological study revealed increased atrial-and nodal-like cells in the cobalt chloride-pretreated group. Confocal calcium ...

This document provides step-by-step instructions for porting Cobalt to run on your platform. To do so, youll use Starboard, which is Cobalts porting layer and OS abstraction. Starboard encapsulates only the platform-specific functionality that Cobalt uses.. To complete a port, you need to add code to the Cobalt source tree. We recognize that many porters will not want to actually share details of their Starboard implementation with external users. These porters likely have their own source control and will fork Cobalt into their software configuration management (SCM) tools. These instructions take that use case into account and explain how to add your port in a way that will not conflict with future Cobalt source code changes.. ...
NanoMolar Nickel / Cobalt Assay Kit The NanoMolar Nickel / Cobalt Assay Kit is for measurement of nanomolar concentrations of nickel or cobalt (10 nM - 500 nM). The assay is based on the principle that binding the fluorescence dye NMA with nickel or cobalt ions results in decrease of the fluorescence intensity (emission 535 nm, excitation 485 nm). Other metal ions including Mg2+, Ca2+, Zn2+, Mn2+, Al3+, Cu2+ and Ag+ give much lower assay sensitivity. Chelators such EDTA and thiol compounds bind strongly some of the metal ions and should be avoided in the assay.. The assay kit can be used for high-throughput measurements of nickel or cobalt concentrations in biological samples or environmental water samples. The kit can also be used for biochemical assays of enzyme assays associated with nickel or cobalt metabolism.. ...
As previously discussed, cobalt has a low bioaccumulation potential in both aquatic and terrestrial pathways (see section 4.4) and as an essential element for plants and animals (Gal et al 2008) homeostatic mechanisms maintain cobalt concentrations in tissues and body fluids within ideal levels by actively accumulating or depurating cobalt depending on metabolic requirements. Therefore there is no indication of a bioaccumulation potential, hence secondary poisoning is not considered relevant. The PNECoral values represent dietary predicted no effect concentrations, below which food concentrations are not expected to pose a risk to birds or mammals. Although a PNECoral value is not relevant for cobalt, an approximate no effect dietary concentration was estimated for both bird and mammal pathways using a Tier 1 approach according to ECHA TGD R.7.13. In this approach, a default assessment factor was applied to the lowest available NOEC identified for both the bird (7.5.1) and mammal (7.5.2) ...

Cobalt ions can enhance the generation of reactive oxygen species (ROS), which may be the reason for cobalt toxicity. This study aimed to determine whether Co 2+ toxicity in goldfish is related to induced oxidative stress in gills, heart and spleen, and to assess responses of antioxidant systems. Exposure of goldfish to 50, 100 and 150 mg L -1 of Co 2+ for 96 h elevated total hemoglobin in blood by 23, 44 and 78%, respectively. In gills, cobalt exposure enhanced lipid peroxide levels and activities of primary antioxidant enzymes; superoxide dismutase (SOD) rose by 125% and glutathione peroxidase (GPx) increased by 53-296%. Glutathione-S- transferase (GST) activity also increased by 117-157% and glucose-6-phosphate dehydrogenase (G6PDH) enhanced by 46-96%. Heart showed limited effects of fish exposure to 50 or 100 mg L -1 of Co 2+, but the exposure to 150 mg L -1 of Co 2+ elevated concentrations of lipid peroxides by 123% and activities of GPx by 98% and SOD by 208%. The most substantial effects ...

Coordination chemistry research on metal complexes of Schiff bases has shown their potential for applications based on their biological activities, catalytic reactions and as photoelectric materials. 4-Chloro-2-(quinolin-8-yliminomethyl)-phenol (HClQP) is a Schiff base synthesized by condesation of 8-aminoquinoline and 5-chloro-2-hydroxybenzaldehyde. It can be used as an N,N,O-tridentate ligand for the synthesis of new metal complexes of Schiff bases. However, few crystal structural studies on the metal complexes of HClQP have so far been reported (Neves et al., 2009; Vasilchenko et al., 1999). In the present work, we report the first cobalt(III) complex of HClQP in cationic form, with a simple cobalt(II) complex in anionic form as the counterion (Fig. 1).. Crystal structure refinement of the title complex revealed that half of the cobalt(II) of the starting material was oxidized to cobalt(III) under the solvothermal synthesis conditions. The cobalt(III) is six-coordinated by four N atoms and ...

Resource potential of cobalt in India is practically negligible. Cobalt in marine manganese nodule though known since long, its report from terrestrial manganese ore is least observed. This paper reports the occurrence of cobalt in low-grade manganese ores of Bonai-Keonjhar belt, Orissa, eastern India and describes methods for its possible enrichment. Cobalt is associated with manganese minerals like lithiophorite (~CoO: 1.2%) and cryptomelane (~CoO: 0.2%). A feed of low-grade siliceous manganese ore containing 26% Mn and 32% SiO2 and 0.08% Co was subjected to physical beneficiation. By processing the low-grade siliceous ore on a dry belt magnetic separator, a product with 47% Mn at 60% recovery could be obtained. It was observed that along with manganese the cobalt value gets enriched (~Co: 0.38%) more than four times in comparison to the feed. Some other traces like Ni, Cu, Zn, Ga, Li etc. also get enriched in the magnetic product. Thus, through simple dry magnetic separation a low-valued
Lambda-Tris(4,7-diphenyl-1,10-phenanthroline)cobalt(III), a photoactivated DNA-cleaving agent, is a small molecular probe of DNA structure. Because of its chirality, the complex cannot bind to regular right-handed B-form DNA but exhibits site-specific cleavage along the polymer strand at conformationally distinct sites such as those in a left-handed conformation. Both coarse and higher resolution mapping experiments using the chiral cobalt complex indicate intriguing conformational variations along the simian virus 40 genome. Highly specific cleavage is evident in the enhancer and promoter blocks and in the region downstream of 3 termini. A specific cleavage pattern borders an alternating purine/pyrimidine stretch within the enhancer, which was found earlier to bind anti-Z-DNA antibodies. Throughout the simian virus 40 genome, variations in structure delineated with the cobalt complex appear to correlate with regions important for control of gene expression. ...

By Peter Kennedy. The Democratic Republic of Congo has granted a monopoly to a new state-owned company that is being set up to buy and market all cobalt in the country that is not mined industrially.. According to a Reuters report, the move is a bid to control the entire artisanal supply chain and boost government revenue through control of prices. Another aim is to exert greater state oversight of working conditions in the artisanal sector, which has been plagued by instances of child labour and other abuses.. That has prompted a number of mining and exploration companies in Canada to try and capitalize on the DRCs image problem by developing projects in North America. They include companies like Fortune Minerals Ltd. [FT-TSX], Canada Cobalt Works Inc., [CCW-TSXV], and First Cobalt Corp [FCC-TSXV, ASX; FTSSF-OTCQB].. Cobalt, with the exception of silver-cobalt ores from the Cobalt Mining Camp in northeast Ontario, is produced primarily as a by-product of copper and nickel and plays a key role ...

The catalytic performances of different commercial cobalt oxides(CoxOy, i.e., Co2O3, Co3O4, and CoO) for peroxymonosulfate(PMS) activation in dye degradation were compared in this study. The CoO/PMS system exhibited the highest catalytic oxidation performances with more than 96% methylene blue(MB) removal at 90 min. The concentration of dissolved cobalt ions from CoO was 1.474 mg/L at neutral pH and 5.231 mg/L at acidic pH at 90 min which accounted for the high MB removal and CoO activated PMS homogeneously compared to the associated CoSO4/PMS. Co3O4 and Co2O3 exhibited similar catalytic performances and characteristics. The MB removal in Co3O4/PMS and Co2O3/PMS system were more than 88% at neutral pH and over 64% at acidic pH, respectively, in 90 min. The concentration of dissolved cobalt ions from Co3O4 and Co2O3 was less than 0.018 mg/L at neutral pH and 0.036 mg/L at acidic pH at 90 min. The MB removal achieved by Co3O4/PMS and Co2O3/PMS were approximately three times higher than that ...

The occurrence of pseudotumours following metal-on-metal hip resurfacing arthroplasty (MoMHRA) has been associated with high serum metal ion levels and consequently higher than normal bearing wear. Measuring ground reaction force is a simple method of collecting information on joint loading during a sit-to-stand (STS). We investigated vertical ground reaction force (VGRF) asymmetry during sit-to-stand for 12 MoMHRA patients with known serum metal ion levels. Asymmetry was assessed using two methods: a ratio of VGRF for implanted/unimplanted side and an absolute symmetry index (ASI). It was found that subjects with high serum metal ion levels preferentially loaded their implanted sides. The difference between the two groups was most apparent during the first 22% of STS. VGRF ratio showed significant and strong correlation with serum metal ion levels (Spearmans rho = 0.8, p = 0.003). These results suggest that individual activity patterns play a role in the wear of MoMHRA and preferential loading of an
Further details on the read-across approach are given in Appendix 1.1 of the CSR for the oral systemic effects and Appendix 1.2 of the CSR for the inhalation local effects. Cobalt dinitrate is assigned to the read-across groups (i) oral-systemic: bioavailable cobalt substances group and (ii) inhalation-local: reactive Toxicological relevance of the non-common compound The toxicological relevance of the non-common compound in cobalt dinitrate for oral-systemic toxicity is discussed in Appendix 1.1 of the CSR. Human data - inhalation Repeated dose toxicity - local effects The comprehensive discussion of the available human data can be found at the beginning of chapter 5 of the CSR and in section 7.10 of the IUCLID. The overall outcome was that, based on the findings of the epidemiological studies in workers by Swennen et al. (1993) and Verougstraete et al. (2004), Roto (1980) and Sauni et al. (2010) a cobalt concentration of 0.12 mg Co/m³ will be used as NOAEC for setting a DNEL (inhalation, ...

Ischemia-modified albumin (IMA) is assumed “N-terminal modified” albumin which is generated immediately following myocardial ischemia. The diagnosis of IMA is based on reduced cobalt binding affinity to albumin which is attributed mainly to incapability of cobalt to bind at albumin’s modified N-terminus. Although the albumin cobalt binding test was accepted as a potentially powerful marker for discriminating acute coronary syndrome from nonischemic chest pain, its usefulness has been brought into question in recent years. Patients with acutely ischemic myocardium exhibit a rapid increase in serum levels of fatty acids (FAs). Almost all released FAs are strongly bound to albumin which create conformational changes in the protein with resultant reduced cobalt binding affinity. There is a clear metabolic and temporal relationship between IMA measured via albumin cobalt binding testing and serum levels of FAs. In line with what has been suggested recently in the literature, we conclude
A highly selective and sensitive spectrophotometric determination of cobalt (II) was developed. 7-Nitroso-8-hydroxyquinoline-5-sulfonic acid sodium salt was used as the chromogenic reagent for color development. Although other metals form colored chelates with the ligand, it was possible to develop a selective method using McIlvaines pH 8 citric acid-phosphate buffer. Under these conditions, iron(II), iron (III), copper (II), zinc (II), and manganese (II), minerals likely to be compounded with cobalt (II) in geriatric formulations, do not interfere with the precision of the method or the color development. Calcium (II) and magnesium (II) do not form colored chelates with the used ligand. Hormones, vitamins, and additives likely to be present along with the cobalt ion in pharmaceutical formulations do not interfere. The sensitivity is 0.37 mug of cobalt (II)/ml of sample solution. ...
While the individual need for dosage of nickel and cobalt in anaerobic digesters has been established, together with the biochemistry underpinning such need; their co-requisite in anaerobic digestion of acetate has not been extensively studied. In addition, the balance between the catalytic and toxic concentrations of nickel and cobalt in anaerobic acetate digesters is not well documented. The aim of this study was to examine and evaluate the effects of individual and combined dosage of nickel and cobalt on biogas production as well as on methanogenic population balance of a mesophilic (37°C) anaerobic acetate digester so as to determine their catalytic and toxic concentrations. Four semi-CSTR digesters were daily fed acetate at a loading rate of 1.8 g L-1 d-1 and were operated at a HRT of 10 days for this investigation. Co-dosage of nickel and cobalt in anaerobic acetate digesters were found to lead to increased biogas production in an additive manner, with the sole dosage of nickel resulting ...
en] Metallo-beta-lactamases are native zinc enzymes that catalyse the hydrolysis of beta-lactam antibiotics, but are also able to function with cobalt(II) and require one or two nnetal-ions for catalytic activity. The hydrolysis of cefoxitin, cephaloridine and benzylpenicillin catalysed by CoBcII (cobalt-substituted beta-lactamase from Bacillus cereus) has been studied at different pHs and metal-ion concentrations. An enzyme group of pK(a) 6.52 +/- 0.1 is found to be required in its deprotionated form for metal-ion binding and catalysis. The species that results from the loss of one cobalt ion from the enzyme has no significant catalytic activity and is thought to be the mononuclear CoBcII. It appears that dinuclear CoBcII is the active form of the enzyme necessary for turnover, while the mononuclear CoBcII is only involved in substrate binding. The cobalt-substituted enzyme is a more efficient catalyst than the native enzyme for the hydrolysis of some beta-lactam antibiotics suggesting that the ...
Introduction: Over 1 million metal-on-metal (MOM) hip replacements were performed between 2003 and 2010. These prostheses were intended to be more durable than previous models, but have been associated with a higher failure rate. There have also been isolated cases of fulminant cardiomyopathy in patients with very high serum cobalt levels. We screened a cohort of asymptomatic patients with these prostheses for subclinical cardiac abnormalities. Methods: All patients with MOM hip replacements at our centre undergo regular follow-up in the orthopaedic clinic with serum cobalt and chromium levels, and periodic magnetic resonance scanning of the affected joint. We recruited consecutive asymptomatic patients to receive echocardiography and recorded demographic data including age, height, weight, serum cobalt and chromium levels, and date of prosthesis implantation. Echocardiographers were blinded to medical history and laboratory results. The cohort was split into quartiles of serum cobalt. ANOVA, ...
I passed this paper out in the week after students synthesized a series of Werner complexes in the laboratory. Students had been exposed to descriptive inorganic chemistry and periodic trends, symmetry and (rudimentary) group theory prior to this exercise. In the second half of the laboratory session, they had compared the rates of hydration of hexammine, pentammine, and cis-tetrammine chloride cobalt complexes using UV/VIS, so some students were quite familiar with the stability of the hexammine complex. My students had not yet been introduced to ligand field theory, HSAB theory, redox mechanisms, or the 18-electron rule; incorporation of those ideas would be an interesting extension to the activity if your class has already been prepared to discuss those theories. The paper also explicitly mentions the large number of structures in the RCSB protein data bank that make use of cobalt complexation. This could be another option for extending the exercise for an upper-level course.. Most of the ...
This thesis focuses on the study of hydrogen dynamic behavior in a series of proton sponge cations as well as in bis(silyl)hydride organometallic complexes. To understand the dynamic behavior, a new tool, i.e. the three-dimensional vibrational Schrödinger equation has been derived and solved. Three different vibrational patterns for hydrogen motion have been revealed. The classification of proton sponges and bis(silyl)hydride complexes into those with localized and delocalized hydrogen behavior has been proposed. For the organometallic complexes the influence of the vibrational motion of the hydrogen on J(Si−H) spin−spin coupling constants has been studied. Also this thesis presents a study of [Cp*Co(SiR3)2(H)2] cobalt complexes and their iridium analogues to detect possible Si···H interactions. Based on molecular geometries, Wiberg bond indices, and J(Si-H) spin-spin coupling constants, at least two residual Si···H interactions have been detected in cobalt complexes while there are ...
Was the patient in question a drinker of cobalt laced beer? No - but she did have cobalt in her body. She had bilateral DuPuy ASR metal-on-metal hip prostheses that had been placed 5 years and 4 years prior to the heart transplant. She had learned about one year prior to transplantation that the prostheses were being recalled due to a higher than expected failure rate and a protocol for follow up was sent to her. She was advised to get repeat hip imaging and serum cobalt levels done. Pelvic MRI showed reactive areas with fluid collection and the cobalt level was elevated at 287.6 mcg/liter with a reference value of less than 1.0 mcg/liter. The prostheses were removed 11 and 13 months post heart transplantation. She had a complicated course but apparently recovered. Serial cobalt levels were done and 16 months after transplantation remained at 11.8 mcg/liter a significant drop. She also had a chromium level determined at 248.9 mcg/liter about 8 months after transplantation ...

Several cobalt complexes with tripodal chelating ligands Tp and Tp* (Tp = tris(pyrazolyl)borate; Tp* = tris(3,5-dimethyl-pyrazolyl)borate) were synthesized by treating the homoscorpionates of the first generation with CoBr2 under different conditions. These complexes were characterized with X-ray crystallographic determination as well as IR, NMR, MS, and UV-vis spectroscopies. Reaction of KTp with CoBr2 in THF afforded an unprecedented trinuclear Co(II) complex [TpCo(Hpz)Br]2(CoBr2) (1) with Tp as terminal ligands, as well as an oxidized side-product (Tp2Co)(Co2Br6) (2). The terminal Co(II) centers of (1) are octahedrally coordinated while the Co(II) in the bridging unit has a distorted tetrahedral geometry, holding a neighboring Co···Co distance of 3.472 Å. Reaction of KTp* with CoBr2 afforded half-sandwich Tp*CoBr (4) with pseudotetrahedrally coordinated Co(II) center, which is accessible to other donors. Mononuclear Tp*CoSPh (7) and dinuclear (Tp*Co)2O2(pz)2 (8) were prepared through ...

The design of a catalyst for one of the most important electrocatalytic reactions, the oxygen reduction reaction (ORR), was done following the most recent guidelines of theoretical studies on this topic. Aim of this work was to achieve a synergic effect of two different metals acting on different steps of the ORR. The catalytic activity of Ag, already known and characterized, was enhanced by the presence of a monolayer of cobalt subdivided into nanosized islands. To obtain such a controlled nanostructure, a novel method utilizing self-assembled monolayers (SAMs) as templates was employed. In a recent study, we were able to perform a confined electrodeposition of cobalt onto Ag(111) in a template formed by selectively desorbing a short-chain thiol (3-mercaptopropionic acid, MPA) from binary SAMs using 1-dodecanthiols (DDT). [32] This method allows for an excellent control of the morphology of the deposit by varying the molar ratio of the two thiols. Because cobalt does not deposit on silver at an ...

TY - JOUR. T1 - Cation-driven electron transfer involving a spin transition at room temperature in a cobalt iron cyanide thin film. AU - Sato, O.. AU - Einaga, Y.. AU - Iyoda, T.. AU - Fujishima, A.. AU - Hashimoto, K.. PY - 1997/5/15. Y1 - 1997/5/15. N2 - The electronic structure of a cobalt iron cyanide thin film, Na0.4Co1.3[Fe(CN)6]5H2O, was switched from FeIII(low spin)-CN-CoII(high spin) to FeII(low spin)-CN-CoIII(low spin) by exchanging cations in interstitial sites from Na+ to K+. The reverse process was also induced by replacing Na+ with K+. That is, the alkali cations in the interstitial sites dominate the electronic and spin states of the host compound. This type of switching phenomenon can be achieved by choosing a compound with both electronic degeneracy and zeolitic properties.. AB - The electronic structure of a cobalt iron cyanide thin film, Na0.4Co1.3[Fe(CN)6]5H2O, was switched from FeIII(low spin)-CN-CoII(high spin) to FeII(low spin)-CN-CoIII(low spin) by exchanging cations in ...

It is with great sadness that I have to announce the following: I will be moving forward with Cobalt without my brother Phil. His recent activities have made it impossible for the two of us to continue on a creative path. We started Cobalt 12 years ago, and our music has carried us through many storms. I am extremely proud of what we have done. But our ideals no longer match, and it is time to keep going. Ive been working rigorously on the material for Slow Forever, and I am set to enter the studio in June 2015 to begin tracking. The loss of Phil is a devastating blow, but I cant let what has happened stop me from completing my work. I am still unclear as to who will be doing the vocals on the album. I have some people in mind. Or I may do them myself. Well see. But it is ultimately sad to lose Phils relentless presence and savage force. More will be posted as it develops. Thank you to everyone who has supported Cobalt over the years and continues to support the band ...

The absorption spectrum of cobalt(II)-substituted Aeromonas aminopeptidase is markedly perturbed by the presence of equimolar concentrations of D-amino acid hydroxamates and acyl hydroxamates that have previously been shown to be powerful inhibitors of this enzyme (Wilkes, S. H., and Prescott, J. M. (1983) J. Biol. Chem. 258, 13517-13521). D-Valine hydroxamate produces the most distinctive perturbation, splitting the characteristic 527 nm absorption peak of the cobalt enzyme to form peaks at 564, 520, and 487 nm with molar extinction values of 126, 98, and 67 M-1 cm-1, respectively. A qualitatively similar perturbation, albeit with lower extinction values, results from the addition of D-leucine hydroxamate, whereas D-alanine hydroxamate perturbs the spectrum, but does not evoke the peak at 564 nm. In contrast, hydroxamates of L-valine and L-leucine in concentrations equi-molar to that of the enzyme produce only faint indications of change in the spectrum, but the hydroxamates of several other L-amino

This magnificent off-road vehicle has made its mark in the 23 foot segment. Yes, she is expansive, and then some, but the Cobalt R3 is much more than your typical 23 footer.. Let us begin with her physique. The R3 exterior profile is sleek and low. The transom, platform design and aft sunpad are sculpted beautifully creating a smooth and sexy profile. The sunpad backrest is convertible, and the rumble seat is simple and effective.. As we step aboard through the walk-through transom, you will notice the cockpit has an interior beam measurement that is over a foot wider than any competitive runabout. This is no illusion. This interior expansion, Free Space Reclamation, is exactly what Cobalts build process creates. It is most noticeable in the cockpit, which is adorned with seating that wraps around the transom and the port side. The wrap-around yacht style seating is exclusive to a boat her size. Notice the attention to detail in the upholstery with the stitching in perfect harmony. The design ...
