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)

N2 - In an effort to obtain synthetic analogues of water-oxidizing complex (WOC) of photosystem II (PS II) of plant photosynthesis, a Schiff base manganese and a cobalt complex, employing Niten, a SALEN type ligand, have been prepared. 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 ...

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 ...

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.. ...

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%.

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 ...

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 ...

Adverse Reaction to Metal Debris (ARMD) is still a major reason for revision surgeries in patients with metal-on-metal (MoM) hip replacements. ARMD consists of a wide range of alterations in periprosthetic tissues, most important of which are metallosis, inflammation, pseudotumors and necrosis. Studies investigating histopathological findings and their association to implant wear or indirect measures of wear have yielded inconsistent results. Therefore, we aimed to investigate bearing surface wear volume, whole blood and synovial fluid metal ion concentrations, histopathological findings in periprosthetic tissues and their associations. Seventy-eight patients with 85 hips revised for ARMD were included in the study. Prior to revision surgery, all patients had whole blood chromium and cobalt ion levels assessed. In revision surgery, a synovial fluid sample was taken and analyzed for chromium and cobalt. Periprosthetic tissue samples were taken and analyzed for histopathological findings. Explanted

EmailOCEANPORT, N.J. - Cobalt Blue charged from far back to snatch victory from his California rival, E Z Warrior, in capturing the $200,000 Select Stakes on the Breeders Cup undercard Saturday at Monmouth Park. With Garrett Gomez riding for trainer Doug ONeill, Cobalt Blue returned $26 after finishing six furlongs in 1:10.54 over a sloppy track. He was the third-longest shot in a field of nine 3-year-olds. E Z Warrior, ridden by Victor Espinoza, dueled outside of Unbridled Trust for most of the way before edging away in midstretch. At the sixteenth pole, E Z Warrior was still clear, but the torrid run of Cobalt Blue nailed him, with the final margin being a half-length. Appealing Spring rallied late to finish third, another two lengths behind E Z Warrior. Cobalt Blue is owned by the estate of the late Merv Griffin. Earlier in the year, when Griffin was still alive, the colt was considered a Kentucky Derby prospect before he faltered in the Illinois Derby, and he had not won since the San ...

Myocardial ischemia (MI) induces many changes in the body, including pH decrease and electrolyte imbalance. No obvious symptoms of MI appear until irreversible cellular injuries occur. Since early treatment is critical for recovery from ischemia, the development of reliable diagnostic tool is demanded to detect the early ischemic status. Ischemia modified albumin (IMA), formed by cleavage of the last two amino acids of the human serum albumin (HSA) N-terminus, has been considered so far as the most trustworthy and accurate marker for the investigation of ischemia. IMA levels are elevated in plasma within a few minutes of ischemic onset, and may last for up to 6 h. In the present study, we developed a novel assay for the examination of IMA levels to ameliorate the known albumin cobalt binding (ACB) test established previously. We observed a stronger copper ion bound to the HSA N-terminal peptide than cobalt ion by HPLC and ESI-TOF mass spectrometric analyses. The copper ion was employed with ...

TY - JOUR. T1 - Fischer-Tropsch synthesis on Co/ZnO catalyst - Effect of pretreatment procedure. AU - Pan, Zhendong. AU - Bukur, Dragomir B.. PY - 2011/9/19. Y1 - 2011/9/19. N2 - The effect of catalyst pretreatment, using hydrogen or carbon monoxide, on the activity and selectivity of cobalt on ZnO catalyst (10 wt% Co/ZnO) during Fischer-Tropsch synthesis was studied in a fixed bed reactor. Catalyst reduced with hydrogen had higher activity and higher olefin content, and produced less methane than the CO activated catalyst. Catalysts were characterized by means of Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), temperature programmed reduction (TPR), and hydrogen chemisorption (H 2-TPD) with pulse re-oxidation. Reduction of Co 3O 4 occurs in two stages during H 2-TPR and CO-TPR. In the latter case CoO, metallic cobalt, cobalt carbides (Co xC; x = 2 or 3) and carbon (from CO disproportionation) are formed during the reduction process. The existence of Co 0 along with CoO and Co xC, ...
Activation of ammonia and amines occurs during metal vapor synthesis at cryogenic temperatures. The Group IIA metal atoms: magnesium, calcium, strontium, and barium, and the transition metal atoms: chromium, manganese, iron, cobalt, nickel, and zinc react with amines and ammonia. Copper metal atoms do not react. Methane and hydrogen are evoved during warming of the Mn/(CH(,3))(,3)N matrix; methane is evolved during warming of the Mn/(CH(,3)CH(,2))(,3)N matrix. Hydrolysis of the cocondensates yields saturated and unsaturated hydrocarbons, and in some cases, hydrogen is formed. The reaction of certain cocondensates with unsaturated compounds yields hydrogenated products ...

Herein, metallo-pyrophosphate complexes have been designed and synthesized, in which pyrophosphate is chelated to multiple metals, with an emphasis on cobalt and copper metal centers. These complexes have diverse and interesting behaviors ranging from cooperative magnetism to anti-mycobacterial properties. The latter application is one of the main focuses of this work, investigating cobalt(II) and copper(II) pyrophosphate complexes as antibacterial agents. In particular, a cobalt(II) pyrophosphate complex with an aromatic capping donor ligand has selectivity and potency against Mycobacterium tuberculosis, the causative agent of tuberculosis (TB). TB causes up to 10 million incident cases per year, with an estimated annual death toll of two million. The need for innovative TB therapy has been stressed, and this research has resulted in new lead compounds for the treatment of TB, with a cobalt(II) pyrophosphate complex having activity comparable to current first-line TB therapy.

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

We present a comparative study of the toxicity of polyethylene glycol (PEG)-coated cobalt ferrite nanoparticles and nanospheres. Nanoparticles were prepared by hydrothermal method while nanospheres were prepared by solvothermal technique. The surface of nanomaterials was successfully modified with polyethylene glycol. To investigate the morphology of the prepared samples, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, thermogravimetric analysis (TGA), and electron microscopy techniques were employed. Structural analyses confirmed the formation of polycrystalline cobalt ferrite nanoparticles with diameters in the range 20-25 nm and nanospheres in the range 80-100 nm, respectively. Kunming SPF mice (female, 6-8 weeks old) were used to investigate the toxicity induced by cobalt ferrite nanoparticles and nanospheres in different organs of the mice. Biodistribution studies, biochemical indices, histopathological assessments, inflammatory factors, oxidation and
We previously reported on the metal ion concentrations of cobalt, chromium, and titanium that were found in the serum of patients three years after they had undergone primary total hip arthroplasty as compared with the concentrations found in the serum of control patients who did not have an implant. This study is a concise update on the serum metal levels found in a cohort of these patients ten years after the time of hip implantation. Of the original seventy-five subjects, metal ion levels were available for forty patients (53%). Ten patients (hybrid group) had received a hybrid total hip replacement that consisted of a modular cobalt-alloy femoral stem with a cobalt-alloy femoral head that had been inserted with cement and a titanium acetabular socket that had been inserted without cement. Nine patients (cobalt-chromium [CoCr] group) had received an implant with an extensively porous-coated modular cobalt-alloy femoral stem and femoral head along with a titanium acetabular socket; the femoral ...
Cobalamin is a complex organic molecule containing a tetrapyrole corrin ring that is similar in structure to heme but that has a divalent cobalt atom in its center instead of an iron atom. Like heme iron, this cobalt atom binds to two ligands. One is a benzimidazole nucleotide, whereas the other can be either a methyl group (found in methylcobalamin) or an adenosyl group (found in adenosylcobalamin). Cobalamin is present in all foods of animal origin including meat, fish, and dairy products. Food cobalamin is tightly bound to proteins. Following ingestion, some cobalamin in food is transferred to human haptocorrin in saliva. As depicted in Figure 6-1, the low pH of the gastric juice facilitates efficient release and transfer of the remaining food cobalamin to haptocorrin. After transit to the duodenum, the increase in pH enables the transfer of cobalamin from haptocorrin to intrinsic factor, a transport protein secreted by gastric parietal cells. The cobalamin-intrinsic factor complex resists ...
Chemically responsive hydrogels with embedded magnetic nanoparticles are of interest for biosensors that magnetically detect chemical changes. A crucial point is the irreversible linkage of nanoparticles to the hydrogel network, preventing loss of nanoparticles upon repeated swelling and shrinking of the gel. Here, acrylic acid monomers are adsorbed onto ferrite nanoparticles, which subsequently participate in polymerization during synthesis of poly(acrylic acid)-based hydrogels (PAA). To demonstrate the fixation of the nanoparticles to the polymer, our original approach is to measure low-field AC magnetic susceptibility spectra in the 0.1 Hz to 1 MHz range. In the hydrogel, the magnetization dynamics of small iron oxide nanoparticles are comparable to those of the particles dispersed in a liquid, due to fast Néel relaxation inside the particles; this renders the ferrogel useful for chemical sensing at frequencies of several kHz. However, ferrogels holding thermally blocked iron oxide or cobalt ferrite
Not only did the jury find the design of the Pinnacle metal-on-metal hip implant was defective, it also found that Johnson & Johnson and DePuy failed to properly inform the public about the risks. According to an article that appeared on the Fortune magazine website on March 17, the jury awarded approximately $140 million in compensatory damages and about another $360 million in punitive damages. Although the punitive damage award was subsequently reduced by the Court, this remains a huge win for the victims.. More than 8,000 lawsuits involving the Pinnacle metal-on-metal hip implant have been consolidated in a federal court in Texas.. The plaintiffs in the case received the Pinnacle device and claimed that it failed faster than expected due to design flaws. They have alleged that they suffered several different types of health problems as a result, including metal in the blood, tissue death, and bone erosion. They have also claimed the defendants marketed the implant as being safe and durable ...
