Overexpression of the multidrug resistance-associated protein (MRP1) in human heavy metal-selected tumor cells. (1/319)

Cellular and molecular mechanisms involved in the resistance to cytotoxic heavy metals remain largely to be characterized in mammalian cells. To this end, we have analyzed a metal-resistant variant of the human lung cancer GLC4 cell line that we have selected by a step-wise procedure in potassium antimony tartrate. Antimony-selected cells, termed GLC4/Sb30 cells, poorly accumulated antimony through an enhanced cellular efflux of metal, thus suggesting up-regulation of a membrane export system in these cells. Indeed, GLC4/Sb30 cells were found to display a functional overexpression of the multidrug resistance-associated protein MRP1, a drug export pump, as demonstrated by Western blotting, reverse transcriptase-polymerase chain reaction and calcein accumulation assays. Moreover, MK571, a potent inhibitor of MRP1 activity, was found to markedly down-modulate resistance of GLC4/Sb30 cells to antimony and to decrease cellular export of the metal. Taken together, our data support the conclusion that overexpression of functional MRP1 likely represents one major mechanism by which human cells can escape the cytotoxic effects of heavy metals.  (+info)

Chemistry and toxicity of flame retardants for plastics. (2/319)

An overview of commercially used flame retardants is give. The most used flame retardants are illustrated and the seven major markets, which use 96% of all flame-retarded polymers, are described. Annual flame retardant growth rate for each major market is also projected. Toxicity data are reviewed on only those compositions that are considered commercially significant today. This includes 18 compounds or families of compounds and four inherently flame-retarded polymers. Toxicological studies of flame retardants for most synthetic materials are of recent origin and only a few of the compounds have been evaluated in any great detail. Considerable toxicological problems may exist in the manufacturing of some flame retardants, their by-products, and possible decomposition products.  (+info)

Asp45 is a Mg2+ ligand in the ArsA ATPase. (3/319)

The ATPase activity of ArsA, the catalytic subunit of the plasmid-encoded, ATP-dependent extrusion pump for arsenicals and antimonials in Escherichia coli, is allosterically activated by arsenite or antimonite. Magnesium is essential for ATPase activity. To examine the role of Asp45, mutants were constructed in which Asp45 was changed to Glu, Asn, or Ala. Cells expressing these mutated arsA genes lost arsenite resistance to varying degrees. Purified D45A and D45N enzymes were inactive. The purified D45E enzyme exhibited approximately 5% of the wild type activity with about a 5-fold decrease in affinity for Mg2+. Intrinsic tryptophan fluorescence was used to probe Mg2+ binding. ArsA containing only Trp159 exhibited fluorescence enhancement upon the addition of MgATP, which was absent in D45N and D45A. As another measure of conformation, limited trypsin digestion was used to estimate the surface accessibility of residues in ArsA. ATP and Sb(III) synergistically protected wild type ArsA from trypsin digestion. Subsequent addition of Mg2+ increased trypsin sensitivity. D45N and D45A remained protected by ATP and Sb(III) but lost the Mg2+ effect. D45E exhibited an intermediate Mg2+ response. These results indicate that Asp45 is a Mg2+-responsive residue, consistent with its function as a Mg2+ ligand.  (+info)

Short report: improved diagnosis and follow-up of canine leishmaniasis using amastigote-based indirect immunofluorescence. (4/319)

A comparison of an indirect immunofluorescence test using promastigotes (IFATp) or cultured amastigotes (IFATa) in the diagnosis and follow-up of canine leishmaniasis caused by Leishmania infantum was carried out. Results obtained with both diagnostic methods were in good agreement although the IFATa titration was more sensitive than the currently used IFATp without losing specificity. The higher sensitivity of the amastigote-based IFAT resulted in an earlier diagnosis in the absence of clinical signs. Both methods showed comparable results for monitoring the clinical evolution of naturally infected and treated (meglumine antimoniate plus allopurinol) dogs.  (+info)

High frequency of serious side effects from meglumine antimoniate given without an upper limit dose for the treatment of visceral leishmaniasis in human immunodeficiency virus type-1-infected patients. (5/319)

Organic pentavalent antimonials are one of the mainstays of treatment for visceral leishmaniasis (VL). Few data are available on the toxicity and efficacy of these drugs at the dosing schedule recommended by the Centers for Disease Control and Prevention (CDC) (Atlanta, GA). We analyzed 25 VL episodes in human immunodeficiency virus (HIV)-infected patients who were treated with meglumine antimoniate (MA) at the CDC-recommended dose in southern Spain. Adverse effects were observed in 14 (56%) VL episodes. In 7 (28%), treatment with MA was permanently discontinued due to serious adverse effects that included acute pancreatitis, acute renal failure, and leukopenia. Three (12%) patients died during therapy due to severe acute pancreatitis attributable to MA. The dosing regimen of MA currently recommended for treating VL is associated with a high rate of serious side effects in HIV-1-infected patients.  (+info)

Roles of endogenous gamma interferon and macrophage microbicidal mechanisms in host response to chemotherapy in experimental visceral leishmaniasis. (6/319)

In experimental visceral leishmaniasis, in which the tissue macrophage is the target, in vivo responsiveness to conventional chemotherapy (pentavalent antimony [Sb]) requires a T-cell-dependent mechanism. To determine if this mechanism involves gamma interferon (IFN-gamma)-induced activation and/or specific IFN-gamma-regulated macrophage leishmanicidal mechanisms (generation of reactive nitrogen or oxygen intermediates, we treated gene-deficient mice infected with Leishmania donovani. In IFN-gamma gene knockout (GKO) mice, Sb inhibited but did not kill intracellular L. donovani (2% killing versus 76% in controls). Sb was active (>94% killing), however, in both inducible nitric oxide synthase (iNOS) knockout (KO) and respiratory burst (phagocyte oxidase)-deficient chronic granulomatous disease (X-CGD) mice. Sb's efficacy was also maintained in doubly deficient animals (X-CGD mice treated with an iNOS inhibitor). In contrast to Sb, amphotericin B (AmB) induced high-level killing in GKO mice; AmB was also fully active in iNOS KO and X-CGD animals. Although resolution of L. donovani infection requires iNOS, residual visceral infection remained largely suppressed in iNOS KO mice treated with Sb or AmB. These results indicate that endogenous IFN-gamma regulates the leishmanicidal response to Sb and achieves this effect via a pathway unrelated to the macrophage's primary microbicidal mechanisms. The role of IFN-gamma is selective, since it is not a cofactor in the response to AmB. Treatment with either Sb or AmB permits an iNOS-independent mechanism to emerge and control residual intracellular L. donovani infection.  (+info)

Ultrastructural histochemical alteration of the plasma membrane in chronic myelocytic leukemia. (7/319)

Ultrastructural histochemical evaluation of the surface of normal human blood and bone marrow cells exposed to the pyroantimonate-osmium (PAO) reaction indicated the selective binding of pyroantimonate to certain cations (calcium, magnesium, and possibly sodium) associated with the plasma membrane of neutrophilic leukocytes and their developmental forms. Other leukocytes and their precursors did not exhibit plasma membrane PAO reactivity. The extent of surface binding was related to cell maturity, with maximal labeling evident in the mid and late promyelocytes; decreased binding occurred with subsequent maturation while myeloblasts were nonreactive. This study was initiated to ascertain if histochemical surface modifications of neutrophilic cells occur in certain myeloproliferative disorders. In this regard, we have been able to demonstrate a distinctive defect in the plasma membrane PAO binding characteristics of the leukemic cells in chronic myelocytic leukemia (CML). Limited binding of pyroantimonate to the plasma membrane of the leukemic cell series in four patients with CML contrasted with that of the normal granulocytic cell series and the neutrophilic cells seen in myelomonocytic leukemia (two patients), myelofibrosis (one patient), and acute myelocytic leukemia (three patients). Comparison of surface PAO reactivity of neutrophilic cells in all stages of maturation in two patients with CML in blast crisis revealed that, in the patient with 30% circulating blast cells, PAO reactivity was identical to that noted in CML, while in the patient with 80% circulating blast forms, the PAO reactivity of the maturing neutrophilic cells more nearly resembled that observed in neutrophilic cells from normal individuals. Many neutrophilic cells from patients with myelofibrosis and myelomonocytic leukemia and from one patient in severe blast crisis had large surface deposits of pyroantimonate considered to reflect increased membrane-associated reactive cation.  (+info)

Concentrations of antimony in infants dying from SIDS and infants dying from other causes. (8/319)

OBJECTIVES: Raised concentrations of antimony have been found in infants dying of sudden infant death syndrome (SIDS). The presumed source of this antimony is toxic gases generated from fire retardants that are present in cot mattresses. The aim of this study was to determine the role of antimony in SIDS. DESIGN: Samples of liver, brain, serum, and urine were collected from all patients dying from SIDS and a group of aged matched control infants who had died of other causes. SETTING: Nationwide study in Ireland. SUBJECTS: 52 infants dying from SIDS and 19 control infants aged > 7 days and < 1 year. RESULTS: The median concentration of antimony in the liver and brain of infants dying of SIDS was < 1 ng/g, with no difference detected between the infants dying from SIDS and the control infants. The range of antimony in the serum of infants dying of SIDS was 0.09-0.71 microg/litre (median, 0.26). Although no difference was found between infants dying from SIDS and control infants, SIDS infants were found to have higher concentrations when compared with healthy infants in the 1st year of life, probably as a result of release of antimony into serum after death. Urine antimony concentrations in infants dying from SIDS were < 3.91 ng/mg (corrected for creatinine) and similar to values found both in control infants and healthy infants. CONCLUSION: There is no evidence to support a causal role for antimony in SIDS.  (+info)

A process is provided for separation of at least one metal sulfide from a mixed sulfide concentrate. The process may comprise: subjecting the mixed sulfide concentrate to flotation in which at least one sulfide comprising antimony, arsenic and a first metal is floated and at least one sulfide comprising a second metal is depressed. The flotation yields a first metal concentrate having the at least one sulfide comprising antimony, arsenic and the first metal and a second metal concentrate having the at least one sulfide comprising the second metal. The first metal concentrate is leached to yield a further concentrate and a leach solution. The further concentrate comprises the first metal and the leach solution comprises soluble antimony and soluble arsenic. The process may further comprise oxidizing the leach solution to yield an antimony precipitate and an arsenic solution, and forming a stable arsenic compound from the arsenic solution.
Upon dissolution in aqueous media at physiologically relevant concentrations and pH conditions, the only aqueous antimony species emerging from all considered trivalent antimony substances is the trivalent antimony cation. In vitro bioaccessibility testing in various artificial body fluids (Hedberg et al., 2010) has shown that diantimony tris(ethylene glycolate) compared to diantimony trioxide has a lower release rate of antimony ions, thus read-across warrants an intrinsic conservatism. With respect to systemic toxicity, read-across from diantimony trioxide toward diantimony tris(ethylene glycolate) is justified. Please also refer to the study results presented in section 4.8 and 7.1.1 of the technical dossier (IUCLID) and in section 1.3 and 5.1.1 of the CSR. The following conclusions can be drawn for diantimony trioxide and by read across, also for diantimony tris(ethylene glycolate): Skin: The Committee for Risk Assessment (RAC) of the European Chemicals Agency (ECHA) concluded that a ...
Summary A series of experiments was undertaken to evaluate the prophylactic, suppressive and therapeutic effects of four compounds against Schistosoma mansoni infections in rhesus monkeys. Marked therapeutic activity was obtained with an olive oil suspension of antimony dimercapto succinic acid in lower doses than those required for the sodium antimony dimercapto succinate in water. These results would suggest that sustained levels of antimony may result in enhanced schistosomicidal activity, thus permitting the use of smaller doses. Anti-schistosomal action was also observed with two non-antimonial compounds. However, one of these, a dicarbonic acid hydrazide, was active only in large doses administered parenterally. Although quantities of eggs in the stools were greatly reduced, considerable numbers of live worms remained at necropsy. The nitro-thiazole derivative, however, manifested prophylactic, suppressive and curative effects in doses seemingly well tolerated. This was shown by a marked reduction

There are substantial environmental concerns with the recycling of polyester right now. Most polyester contains antimony which is not a benign chemical - it is a likely carcinogen, among other issues. Recycling polyester releases encapsulated antimony, thus creating antimony trioxide, which has a toxicity profile less sanguine even than antimonys. If your green desire is to help stem the use of industrial chemicals and their pollution of the earth - and of people - this is a step you would choose to avoid. Thanks to the cradle to cradle people, antimony free polyester does exist. Antimony free polyester fabrics are available. Unfortunately, although antimony free polyester - that is, non-toxic polyester (and there is controversy about whether the antimony is a threat to humans during use and before end of life) - does exist, there is no viable program for recycling it and keeping it segregated from other types of polyester right now. In fact, there is no viable program for the recycling of ...

Leishmania donovani is the etiological agent of visceral leishmaniasis in the Indian sub-continent (ISC). Leishmania are Protozoa alternating between two life forms: the extracellular promastigotes in the insect vector and the intracellular amastigotes in the mammalian host. Pentavalent antimony was the first line drug in the ISC from 1923 to 2005 when it was abandoned because of treatment failure and drug resistance. In a previous phylogenomic study, we were able to show the circulation of two genetically different L. donovani in the ISC (i) the Core Group (CG) endemic in the Gangetic plains and (ii) another population called ISC1 found in the Nepalese high-lands. Interestingly, 100% of the CG isolates showed a unique ancestral character, the intra-chromosomal amplification (ICA) of the H- and M-loci. However, the link between the genomic features and drug resistance was not clear. The main hypothesis of this PhD was that gene dosage would play a major role in the development of antimonial ...

There are no laboratory studies available on bioaccumulation of antimony in earthworms. However, concentrations of antimony in soil and invertebrates at locations close to an antimony smelter have been measured by Ainsworth et al. (1990b). The highest antimony concentrations were found in earthworms (Oligochaeta). The dry weight concentrations (including gut contents) were 398 ± 94 mg/kg, 213 ± 65 mg/kg and 109 ± 28 mg/kg, at 100m, 250m and 450m downwind of the smelter. The EU RAR for diantimony trioxide used measurements presented in figures in Ainsworth et al.(1990b) to derive the following approximations for the 0-5, 5-10, 10-15 and ,15 cm depths for the 100m, 250m and 450m sites: 367, 253, 220 and 171 mg Sb/kg dw, 204, 155, 114 and 94 mg Sb/kg dw, and 180, 180, 163 and 135 mg Sb/kg dw, respectively.

Antimony trisulfide (Sb2S3) is found in nature as the crystalline mineral stibnite and the amorphous red mineral metastibnite. It is manufactured for use in safety matches, military ammunition, explosives and fireworks. It also is used in the production of ruby-colored glass and in plastics as a flame retardant. Historically the stibnite form was used as a grey pigment in paintings produced in the 16th century. It is a semiconductor with a direct band gap of 1.8-2.5 eV.[citation needed] With suitable doping, p and n type materials can be produced. Sb2S3 can be prepared from the elements at temperature 500-900 °C: 2Sb + 3S → Sb2S3 Sb2S3 is precipitated when H2S is passed through an acidified solution of Sb(III). This reaction has been used as a gravimetric method for determining antimony, bubbling H2S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb2S3 which turns black under the reaction conditions. Sb2S3 is readily oxidised, reacting vigorously with oxidising ...
Abstract Standard courses of pentavalent antimonials frequently fail to cure cutaneous, mucocutaneous, and visceral leishmaniasis, and characteristically fail to cure diffuse cutaneous We have determined the in vitro sensitivity of clinical isolates of Leishmania to pentavalent antimony to determine if inherent drug resistance of the parasite is responsible for treatment failures in human beings. Intracellular amastigotes resulting from promastigote-initiated infection of human macrophages were exposed to pentavalent antimony for 6 days at 34.5-35°C. Amastigotes from clinically sensitive simple cutaneous lesions exhibited a range of in vitro sensitivity. Four strains were ≥90% eliminated and two strains were 70-75% eliminated in vitro by concentrations of antimony (15-20 µg Sb/ml), comparable to peak achievable serum levels in humans. Amastigotes from initially clinically resistant simple cutaneous lesions showed a wider range of sensitivities. Five strains were ≥90% eliminated, but one strain was
Researchers at Griffith University in Australia have developed a new diffusive gradients in thin films (DGT) method to determine the concentration of antimony in polluted waters. This new technique also allows them to measure in situ the speciation of this metalloid in its different oxidation states. Speciation could be carried out before using solid phase extraction (SPE) cartridges, but these present some limitations when it comes to analysing some complex mixtures like seawater.. On the other hand, DGT is a sampling technique that can be used to measure a myriad of analytes in different mixtures. DGT uses a combination of hydrogel-based layers to extract and retain the analyte, that can be eluted and determined later on. This technique has been used to measure trace metals, metalloids, sulphides, phosphates and ammonium. In this case, to enhance the affinity of DGT membranes to antimony, researchers have used thiol-based silica gel layers.. In this paper, the authors present a combination of ...

Mass spectrometry (MS) is a powerful analytical tool with its application in the field of biological sciences for identification of proteins, defining post-translational modifications, studying protein expression and protein interactions. This thesis presents MS analyses of proteins for defining modifications observed during sample preparation and identification of proteins isolated from clinical samples and microorganisms. The first part of the thesis includes proteomic analysis of antimony resistant L. tropica. The results clearly indicated that the generation of antimony resistance by parasites, either in host organism or in vitro, causes alteration of protein expression levels, and the mechanism of antimony resistance in host organism and in vitro conditions follow different strategies. In the second part of the study, proteomic analysis of Bence Jones proteins isolated from urine of multiple myeloma patients was performed. Gel electrophoresis and MS analysis revealed that the proteins from ...
Abstract : Antimony sulfide (Sb2S3) has gained extensive attention in solar cells due to their potential as a low-cost and earth abundant absorber material. In solar cell absorber, the optoelectrical properties such as energy band gap and absorption coefficient of Sb2S3 play an important role, which have strong relationships with their crystal structure, lattice parameter and crystallite size.��Hence in the present investigation, Sb2S3 powder samples were exposed to biofield treatment, and further its physical, structural and spectral properties are investigated. The particle size analysis showed larger particle size and surface area after treatment. X-ray diffraction (XRD) analysis revealed polycrystalline orthorhombic structure with superior crystallinity in treated Sb2S3 along with significant changes in the lattice parameters, which led to changes in unit cell volume and density. XRD data analysis indicates that crystallite size was increased by around 150% in treated sample. In ...

Chemotherapy of leishmaniasis is principally predicated on antimonials. and 13e werent dangerous against fibroblasts, macrophages, or dendritic cells. Jointly, these results claim that the aziridine-2,3-dicarboxylates 13b and 13e are potential antileishmanial business lead substances with low toxicity against web host cells and selective antiparasitic results. Chemotherapy against leishmaniasis is situated generally on antimony substances, initially defined in 1912 by Vianna (42) in Brazil as trivalent antimonials [Sb(III)]. These substances display high toxicity and a small therapeutic window, conditions that led to the introduction of the pentavalent antimonium [Sb(V)] agencies sodium stibogluconate (Pentostam) and meglumine antimoniate (Glucantime), presented around 1940 (31, 38). Pentavalent antimonium substances display a wider healing window and therefore became the medications of preference against leishmaniasis. Nevertheless, their toxicity causes critical unwanted effects that PXD101 ...
For localization of pyroantimonate-precipitable cations, mouse testes were fixed with a saturated aqueous solution of potassium pyroantimonate (pH about 9.2, without addition of any conventional fixative), hardened with formaldehyde, and postosmicated. A good preservation of the cell membranes and over-all cell morphology is obtained as well as a consistent and reproducible localization of the insoluble antimonate salts of magnesium, calcium, and sodium. Four sites of prominent antimonate deposits are revealed, besides a more or less uniform distribution of the precipitates. These sites are: (a) In the walls of the seminiferous tubules, localized in two concentric layers corresponding to the inner and outer layers of the tubular wall; (b) Around the blood vessels and adjacent connective tissue; (c) At the area of contact between the Sertoli cell and spermatids, where a double line of precipitate surrounds the head of the mature spermatids; and (d) In the cell nuclei, disposed between regions of ...

Antimony pentachloride is a highly corrosive substance that should be stored away from heat and moisture. It is a chlorinating agent and, in the presence of moisture, it releases hydrogen chloride gas. Because of this, it may etch even stainless-steel tools (such as needles), if handled in a moist atmosphere. It should not be handled with non-fluorinated plastics (such as plastic syringes, plastic septa, or needles with plastic fittings), since it melts and carbonizes plastic materials.[9] ...

Abstract:. Introduction: Antimony potassium tartrate is a component of certain expectorants in homeopathic medicine, particularly in those classified as antihomotoxic remedies. Given that antihomotoxic products are prepared with different epistemological and methodological statuses, they should be tested to prevent eventual toxic effects. Methods: In this study, we evaluate the possibility of using continuous flow hydride generation (HG) coupled with Fourier transforms infrared spectroscopy (FTIR) for determining antimony concentration in antihomotoxic products containing antimony potassium tartrate. Results: The results showed good agreement with the theoretically estimated values for the liquid commercial samples, in the range from 0.5 μg/mL to 30 μg/mL, following the principle of decimal dilutions used in homeopathic medicine. Liquid samples were analyzed directly from the commercial container. Discussion: In the absence of regulatory standards for antihomotoxic products, the proposed ...

Nose surgery can take place under general or local anesthesia, meaning that the patient is either awake or asleep while the work is done. The surgeon will carry out the changes to the patients nose by making incisions inside it, where the scars wont be noticeable in the future. They may then take away some bone and cartilage or add tissue, depending upon the changes that are required. Once all of this is done, the skin is put back in place, and a temporary splint is located outside the nose to provide additional support while the nose heals from the surgery. The full procedure normally takes up to 2 hours to complete, although the complexity of the case and the working methods of the Antimony rhinoplasty doctor in question can make it longer or shorter.. ...

Capillary electrophoresis with indirect UV detection was used to determine simultaneously arsenic, selenium, antimony and tellurium compounds. The separation was achieved in a fused silica capillary filled with an electrolyte solution containing sodium chromate and an electroosmotic flow modifier, trimethyltetradecylammonium hydroxide (TTAOH). The effect of the TTAOH concentration and electrolyte solution pH on the electrophoretic mobility of the species was studied. The best simultaneous separation of these species was achieved with 0.5 mM TTAOH and an electrolyte pH of 11.2 within 5 min. Detection limits range from 13 μg 1-1 for Se(VI) to 509 μg 1-1 for Te(IV) with electromigrative injection. The reproducibility was below 10% and linearity was verified in the 0-100 mg 1-1 range for all species. Interferences by other inorganic ions were studied. This method was applied to the determination of metalloids in a spiked drinking water. Water extracts of industrial soils were analysed and results were

Thin film all-solid-state secondary microbatteries are extensively studied since the 1990s [1-3]. These systems present specific features such as reduced surface, high thermal resistance, excellent cycle life, absence of liquid electrolyte, etc. that make them the most suitable energy sources for some emerging applications (real time clock, medical implants, secured smart cards, etc.). All-solid-state microbatteries are realized by successive deposition of thin films with a total thickness of less than 20 µm. The corresponding manufacturing steps are mainly carried out using physical vapor deposition processes such as thermal evaporation or sputtering, which are commonly used in the microelectronics industry. Then, microbattery systems need to tolerate microelectronics constraints, namely the solder reflow (T°C , 260°C) and short-circuits during manufacturing. Lithium metal anode is then no longer satisfactory. In this work, we study two original anode materials: antimony Sb and bismuth Bi. ...
Pure and Antimony (Sb, x = 0.01%, 0.02% and 0.03%) doped Bi0.5Na0.5TiO3 electro ceramics were successfully synthesized by a conventional solid state reaction route. X-ray diffraction analysis showed that a distinct 002/200 peak splitting appears when doping percentage changes from 0.02 to 0.03, referring to a hexagonal symmetry. The data show the Lorentzian deconvolution of the 002 and 200 peaks of the tetragonal phase and the 202 peak of the rhombohedral phase. There is no significant change in the Raman spectra for the prepared compositions while some additional peaks around 151, 281, 585 and 853 cm-1 compared to the peaks observed in BNT. It may be possible that a morphotrophic phase boundary (MPB) exists around x = 0.03. Analysis of peak positions, widths and intensities of Raman spectroscopy study also confirmed the existence of structural change around x = 0.03 composition.

HERING says of this drug, An invention of the alchemists, very popular with them, forbidden by the French Academy, finally introduced and much used and much abused by the Old School. Old School, Farrington says, does not make much play in these days with Tartar emetic: and he is borne out by its present day teachings, for we are told (Hale White) that many years ago an ointment, of Tartar emetic was applied as a counter irritant: but it causes too much pain and is now seldom used. That Tartar emetic cannot be recommended as an emetic, its action is slow and its general depression great. It should never be given to produce purgation. It is also pronounced an undesirable expectorant. But this is qualified. The only cases in which it is permissible are those in which an emetic is required for laryngitis, bronchitis, or some other acute inflammatory condition of the respiratory tract for then its depressant action on the circulation may perhaps be beneficial, but usually Ipecacuanha is ...

TY - JOUR. T1 - A structural study of tin-antimony oxide catalysts by high-resolution electron microscopy. AU - Berry, Frank J.. AU - Smith, David J.. PY - 1984/7. Y1 - 1984/7. N2 - Tin-antimony oxide catalysts prepared by the calcination of precipitates have been investigated by high-resolution electron microscopy. The exposure of the catalysts prepared at low temperatures to gaseous atmospheres containing hydrocabon and oxygen results in a segregation of antimony from the poorly crystalline rutile-type solids and the development of an amorphous material. The catalysts containing low concentrations of antimony are also partially converted to a non-rutile-type crystalline phase. Prolonged calcination in air of the used catalysts at high temperatures leads to the attainment of bulk equilibrium and the formation of solid solutions of antimony in tin(IV) oxide. Treatment of the equilibrated crystalline catalysts prepared at high temperatures in the hydrocarbon and oxygen gas stream gives rise to ...

Arsenic, Sb, Tl and Bi are highly toxic elements and found in trace amounts in the earths crust. Various investigations documented that the atmospheric load and geochemical cycles of these rare elements in the Northern Hemisphere where industrial activities are intensive, have been controlled by changing emissions from various natural and industrial processes in modern times. In order to understand the atmospheric behavior of As, Sb, Tl, and Bi in the most remote areas in the Southern Hemisphere, we have determined these elements in a continuous series of 80 snow samples from a 4-m snow pit, covering 50 years from 1957 to 2007, at Dome Fuji in East Antarctica. They were measured by ultrasensitive inductively coupled sector field mass spectrometry (ICP-SFMS) under a Class 10 ultraclean condition. Concentrations of As, Sb, Tl, and Bi are extremely low, with mean values of 11.3 pg g-1 for As, 0.29 pg g-1 for Sb, 0.07 pg g-1 for Tl, and 0.12 pg g-1 for Bi, respectively.

Mussel shell (MS), cow bone (CB) and biochar (BC) were selected to immobilize metals in an army firing range soil. Amendments were applied at 5% (wt) and their efficacies were determined after 175 d. For metal phytoavailability test, maize (Zea mays L.) plants were cultivated for 3 weeks. Results showed that all amendments decreased the exchangeable Pb by up to 99% in planted/unplanted soils. Contrarily, exchangeable Sb were increased in the MS- and CB-amended soils. The rise in soil pH (~1 unit) by the amendments affected Pb and Sb mobility in soils. Bioavailability of Pb to maize was reduced by up to 71% in the amended soils. The Sb uptake to maize was decreased by up to 53.44% in the BC-amended soil. Sequential chemical extractions showed the transformation of easily available Pb to stable residual form with the amendment treatments.

The cells were reconnected as shown above and the potentials across both cells were carefully adjusted to match each other using a high resolution Hewlett-Packard digital voltmeter. The currents via the cells were measured with a specially constructed differential shunt resistor network having a matching accuracy batter than 0.1% . The current of the Ca-Ca cell was measured across A - B, the current of the Sb-Ca cell was measured across C - D and the differential was monitored across B - D, again using the H-P instrument.. (In previous testing an untreated antimony cell had drawn more than six times the electrolysis current of a calcium cell. An antimony cell containing Batteryvitamin S2 in the negative but no formation catalyst in the electrolyte drew roughly three times the electrolysis current of the calcium cell.). Subsequent cycling of the cells in parallel was performed. Discharging at the 5 hour rate down to 1.50 V/cell and charging at the 20 hour rate up to an average of 2.60 V/cell - ...

Summary of Facts and Submissions. I. European patent application 81 102 182.3 filed on 23 March 1981 and published on 30 September 1981 with publication number 36 661, claiming priority of the prior application on 24 March 1980 was refused by the decision of the Examining Division of the European Patent Office dated 22 January 1985. The decision was based on Claims 1 to 14 filed on 2 May 1983. The main claim was worded as follows:. A process for catalytically cracking hydrocarbons in the absence of antimony utilizing a passivating agent for the passivation of catalyst-contaminating metals, characterized by using a passivating agent containing tin, phosphorus and sulphur.. II. The stated ground for refusal was that the subject-matter of Claim 1 did not involve an inventive step. The cited closest prior art EP-A-1642 (1) described a process using a passivating agent containing tin, phosphorus and sulphur but the use of a combination of these three in the absence of antimony was not specifically ...

  • CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of 11 substances referred to collectively as the Antimony-containing Substances Group. (canada.ca)
  • Results from surveys under section 71 of CEPA indicate that the 11 antimony-containing substances in this group were manufactured or imported above reporting thresholds in either 2008 or 2011. (canada.ca)
  • The ecological risks of the 11 substances in the Antimony-containing Substances Group were characterized using the Ecological Risk Classification of Inorganic Substances (ERC-I). The ERC-I is a risk-based approach that employs multiple metrics considering both hazard and exposure in a weight of evidence. (canada.ca)
  • Exposure profiling considered two approaches: predictive modeling using a generic near-field exposure model for each substance, and an analysis of measured concentrations collected by federal and provincial water quality monitoring programs using antimony concentrations as a conservative indicator of exposure for the 11 substances. (canada.ca)
  • The ERC-I identified these 11 antimony-containing substances as having low ecological concern. (canada.ca)
  • Considering all available lines of evidence presented in this screening assessment, there is a low risk of harm to the environment from the 11 antimony-containing substances. (canada.ca)
  • The following resources provide information about occupational exposure to antimony. (cdc.gov)
  • Criteria for a Recommended Standard: Occupational Exposure Standard for Antimony -DHHS (NIOSH) Publication No. 78-216. (cdc.gov)
  • Antimony can be measured in the urine, feces, and blood for several days after exposure. (cdc.gov)
  • Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. (mdpi.com)
  • Exposure to antimony occurs in the workplace or from skin contact with soil at hazardous waste sites. (cdc.gov)
  • Exposure to antimony at high levels can result in a variety of adverse health effects. (cdc.gov)
  • The quinoline derivatives and their antimony(III) complexes were evaluated for their anti-trypanosomal activity as well as for their cytotoxicity against HL-60 and Jurkat human leukemia cell lines. (nih.gov)
  • Polyus, controlled by the family of Russian tycoon Suleiman Kerimov, said it will produce the metal at its large Olimpiada gold deposit in Russia which has reserves of high-content antimony ore. (reuters.com)
  • The total amount of high content antimony ore to be mined at the Olimpiada deposit between 2017 and 2026 is estimated at 11 million tonnes. (reuters.com)
  • Liu and his team, postdoctoral fellow Long Cheng and graduate student Chenmu Zhang, outline their discovery that, in its 2D form, the chemical element antimony may serve as a suitable alternative to silicon. (nanowerk.com)
  • Liu has only demonstrated its potential through theoretical computational methods but is confident it can exhibit the same properties when tested with physical antimony samples, which is the team's next step. (nanowerk.com)
  • Chemical methods specific for the determination of the levels of trivalent antimony (Sb +3 ) and pentavalent antimony (Sb +5 ) were used to investigate proprietary formulas used to treat leishmaniasis. (ajtmh.org)
  • Trivalent antimony was determined by differential pulse polarography, whereas Sb +5 was determined by iodine titration. (ajtmh.org)
  • Antimony is probably only slightly toxic in human beings, though in rats it affects the heart and reduces the life span. (healthy.net)
  • William Shotyk, a Canadian scientist working at the University of Heidelberg, studied 132 brands of bottled water stored for six months, and found significant levels of the toxic metal antimony had leached out of the PET bottles into the water. (treehugger.com)
  • Antimony is toxic and several states have identified it as a safety concern for children's products. (ewg.org)
  • Antimony is a dangerous and toxic pollutant listed as a priority by the US Environmental Protection Agency. (rsc.org)
