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)

Antimony (Sb) is a toxic, flaky, brittle element with the symbol Sb (Latin: stibium, meaning "mark") and atomic number 51. It does not react with air, but burns brightly when ignited. Since it is not a metal, antimony is a poor conductor of both heat and electricity. The stable form of antimony is a blue-white metalloid. Yellow and black antimony are unstable non-metals. Antimony is used in flame-proofing, paints, batteries, ceramics, enamels, as a hardener for lead and other metals, and in a wide variety of alloys, electronics, and rubber. The ancient Egyptians used black stibnite as eye make-up. Antimony is a member of the "pnictogen" (group 15) of the periodic table. This is the area that has a metal near the bottom (bismuth) and some nonmetals near the top (nitrogen). Antimony in between-It is one of the few elements which is neither a metal or a non-metal. Antimony was known as an element at least as far back as the alchemists. It was first scientifically studied in 1707 by Nicolas Lemery. ...

A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented. The influences of molten salt addition and composition, ferric oxide dosage, smelting temperature and duration on extraction efficiency of antimony were investigated in details, respectively. The optimum conditions were determined as follows: 1.0 time stoichiometric requirement (α) of mixed sodium salt (αsalt = 1.0), WNaCl:Wsalt = 40%, αFe2O3 = 1.0, Wcoke:Wstibnite = 40%, where W represents weight, smelting at 850 °C (1123 K) for 60 min. Under the optimum conditions, the direct recovery rate of antimony can reach 91.48%, and crude antimony with a purity of 96.00% has been achieved. 95.31% of sulfur is fixed in form of FeS in the presence of iron oxide. Meanwhile, precious metals contained in stibnite concentrate are enriched and recovered comprehensively in crude antimony. In comparison to

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 ...

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 ...
ANTIMONY 521 In exceptional cases the post-mortem appearances of poisoning by antimony may be absent. For instance, in the case of Mrs. Taylor, one of the victims of Dr. Pritchard, where death occurred from acute poisoning by tartar emetic, the post-mortem examination revealed nothing although the poison was detected in the viscera, urine, blood and intestinal contents.44 In poisoning by antimony trichloride the post-mortem appearances will be charring and corrosion of those parts with which it has come into contact. Fig. 172. Microphotograph of Antimony Trioxide Crystals X 400. (R3. Dr. K. N. Bagchi.) Chronic Poisoning1. This occurs from the administration of repeated small doses of tartar emetic. The symptoms are nervous irritability, giddi- ness, headache, nausea, persistent vomiting of bile and mucus, and watery purging sometimes alternating with constipation. The tongue becomes foul; there is loss of voice, and the pulse is weak and rapid. The skin is cold and clammy. There is great ...

This paper describes a procedure for the determination of antimony (III) by differential pulse anodic stripping voltammetry using a mercury film screen-printed electrode as the working electrode. The procedure has been optimized using experimental design methodology. Under these conditions, in terms of Residual Standard Deviation (RSD), the repeatability (3.81 %) and the reproducibility (5.07 %) of the constructed electrodes were both analyzed. The detection limit for Sb (III) was calculated at a value of 1.27×10-8 M. The linear range obtained was between 0.99 × 10-8 - 8.26 × 10-8 M. An analysis of possible effects due to the presence of foreign ions in the solution was performed and the procedure was successfully applied to the determination of antimony levels in pharmaceutical preparations and sea water samples.

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 ...

article{4144201, abstract = {Based on promising results obtained in earlier work on antimony ores, we have investigated the use of natural variation in the isotopic composition of Sb as determined using multi-collector ICP-mass spectrometry (MC-ICP-MS) for provenancing Roman glasses. In antiquity, Sb was used either as a decolourizer or as an opacifier and thus, colourless and opaque coloured glasses from different regions and periods were selected for investigation. Both, the sample digestion and isolation of Sb preceeding isotopic analysis via MC-ICP-MS have been optimized and validated for this type of materials. For this purpose, NIST SRM 610 glass reference material and an in-house standard were employed. Isotope ratio determinations were carried out by MC-ICP-MS, relying on In as an internal standard for correction for instrumental mass discrimination. The merits of external calibration in a sample-standard bracketing approach and the so-called {\textacutedbl}revised Russells ...

Methods, additives and compositions for selectively temporarily sealing high temperature permeable formations penetrated by well bores. The compositions are formed by dispersing a granular additive into an aqueous medium which contains a galactomannan gum treated with potassium pyroantimonate whereby the hydration rate of the gum is retarded at temperatures below about 120 F. but increases at temperatures thereabove. When the composition is introduced into a high temperature permeable formation, it is heated whereby the treated galactomannan gum hydrates and the composition is formed into a stiff gel.

AU - Rheingold, Arnold L.. PY - 2010/11/8. Y1 - 2010/11/8. N2 - Arsenic and antimony triiodide react with 3 equiv of Na[C 5Me4H] in THF to form the yellow tris(tetramethylcyclopentadienyl) derivatives M(C5Me 4H)3 in 61% and 76% yields, respectively. When equimolar amounts of SbI3 and Na[C5Me4H] react in THF, the orange diiodo species Sb(C5Me4H)I2 is produced in 87% yield. The effect on the complexes of the methylated cyclopentadienyl rings varies from minimal to substantial. For example, the properties of the antimony compound Sb(C5Me4H)3 are similar to those of the unsubstituted complex Sb(C5H 5)3; in contrast, As(C5Me4H) 3 and Sb(C5Me4H)I2 are considerably more thermally stable than their parent versions. The complexes are fluxional on the 1H NMR time scale at room temperature. A single-crystal X-ray structure of ...

Stibiconite is a rather rare mineral, but is known among collectors for its first class pseudomorphs. A pseudomorph is an atom by atom replacement of one minerals chemistry to form another completely different mineral. The process leaves the crystal shape of the lost mineral intact. Pseudomorph means false (pseudo) shape (morph). In the case of stibiconite, the mineral that is lost is stibnite, Sb2S3. Stibnites sword-like crystals arranged in radiating clusters are truly works of natural art. A pseudomorph of stibiconite can perfectly match the sword-like shape of stibnites crystals. It can do this because the process is done slowly, allowing the oxygens to replace the sulfurs essentially one atom at a time. However, stibiconite lacks the metallic luster or steel gray color of stibnite. If two classic specimens of the minerals are put side by side the color and luster contrasts along with the similarity of the crystal shapes would simply fasinate the onlooker. As might be guessed, stibiconite ...

Many will remember the "borough mystery," arising out of the death of Maud Marsh, a barmaid at the Crown public house. It afforded another instance of the value of the criminal analyst; though in this case the expert was Dr. Stevenson. He was able to state definitely that the young woman had been given antimony over a considerable period in infinitesimal doses. George Chapman, the landlord of the inn - his real name was Severino Klosowski - was arrested, and the police were led to look into the deaths of two other women who had died under like suspicious circumstances. The bodies were exhumed, and, though two years had elapsed in one case, and six in the other, since burial, Dr. Stevenson found sufficient antimony in each case to ground further capital charges against Chapman, had the case of Maud Marsh been insufficient to hang him. In 1892 the police in South London were baffled by a clever scoundrel. A human monster, they knew, was at large, inducing girls to take capsules, "in order to ...

Kohl (khur, kuhl, kahal, or kohol) is a black substance used by the women of the Arabian Peninsula as eyeliner and eyeshadow. Apart from making the eyes look brighter and larger, kohl was once believed to have value as a protection against eye disease. Its blackness also controls the suns glare in the desert, and thus it is used by both men and women of the desert. Kohl is powdered antimony, a brittle metallic elementary body of bright bluish-white colour and flaky crystalline texture. Artemis imports, a belly dance mail-order supply house, sells both light and darker grades of kohl of fine quality. It can also be found at middle eastern grocery stores, but beware of any powder which does not appear to be very finely and consistently ground. The "kohl" pencils used in modern makeup are a completely different item and should not be applied in the manner the powder is applied, next to the eye. To apply kohl you need: 1) a small stick or large toothpick which has both ends rounded off. Place this ...
In 1947, I was appointed to work at the Medical Research Councils Industrial Injuries and Burns Research Unit, based at the Birmingham Accident Hospital. The director of the new Unit, John Squire, like myself, had done some personnel research in the Services during the war. I also had experience with mepacrine control of Malaria in the Tropics and the treatment of an outbreak of Schistosomiasis in West Africa with intravenous Tartar Emetic. We were both keen to develop clinical research at the Accident Hospital to parallel Leonard Colebrooks bacteriological studies on Burns.. The science teaching at Burton Grammar School was excellent and had encouraged my interest in the history of Science. I thought the history of the noting and testing of treatments would be a promising topic for my MD Thesis. No formal supervision was possible. Having already had experience of working on original papers for my Cambridge "Part II", it was not a big step to work up references - using particularly Index ...

BACKGROUND: Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease caused by a range of Leishmania species. Many treatment modalities have been proposed, although pentavalent antimonials are still considered to be the first-line treatment of CL. However, due to the high cost and adverse effects of antimonials, as well as an increase in the number of resistant strains of CL to antimonials, this study was conducted to compare the efficacy of oral ketoconazole with intralesional meglumine antimoniate (Glucantime, Specia, Paris, France) for the treatment of CL. METHODS: A total of 96 patients with CL were enrolled in the study. The diagnosis of CL was confirmed parasitologically using direct skin smears or skin biopsies. The patients were randomly allocated to two treatment groups. Group A (64 patients) was treated with ketoconazole 600 mg/day for adults and 10 mg/kg per day for children for 30 days. Group B (32 patients) was treated with 6-8 biweekly intra-lesional injections of meglumine ...
In molecular biology, the ars operon is an operon found in several bacterial taxon. It is required for the detoxification of arsenate, arsenite, and antimonite. This system transports arsenite and antimonite out of the cell. The pump is composed of two polypeptides, the products of the arsA and arsB genes. This two-subunit enzyme produces resistance to arsenite and antimonite. Arsenate, however, must first be reduced to arsenite before it is extruded. A third gene, arsC, expands the substrate specificity to allow for arsenate pumping and resistance. ArsC is an approximately 150-residue arsenate reductase that uses reduced glutathione (GSH) to convert arsenate to arsenite with a redox active cysteine residue in the active site. ArsC forms an active quaternary complex with GSH, arsenate, and glutaredoxin 1 (Grx1). The three ligands must be present simultaneously for reduction to occur. ArsA and ArsB form an anion-translocating ATPase. The ArsB protein is distinguished by its overall hydrophobic ...

Leishmaniasis is a complex disease, with visceral and cutaneous manifestations, and is caused by over 15 different species of the protozoan parasite genus Leishmania. There are significant differences in the sensitivity of these species both to the standard drugs, for example, pentavalent antimonials and miltefosine, and those on clinical trial, for example, paromomycin. Over 60% of patients with visceral leishmaniasis in Bihar State, India, do not respond to treatment with pentavalent antimonials. This is now considered to be due to acquired resistance. Although this class of drugs has been used for over 60 years for leishmaniasis treatment, it is only in the past 2 years that the mechanisms of action and resistance have been identified, related to drug metabolism, thiol metabolism, and drug efflux. With the introduction of new therapies, including miltefosine in 2002 and paromomycin in 2005-2006, it is essential that there be a strategy to prevent the emergence of resistance to new drugs; ...
Background. Pentavalent antimonials (Sbv) are the first-line chemotherapy for American tegumentary leishmaniasis (ATL). There are, however, reports of the occurrence of treatment failure with these drugs. Few studies in Latin America have compared the response to Sbv treatment in ATL caused by different Leishmania species. Methods. Clinical parameters and response to Sbv chemotherapy were studied in 103 patients with cutaneous leishmaniasis (CL) in Peru. Leishmania isolates were collected before treatment and typed by multilocus polymerasechain- reaction restriction fragment-length polymorphism analysis. Results. The 103 isolates were identified as L. (Viannia) peruviana (47.6%), L. (V.) guyanensis (23.3%), L. (V.) braziliensis (22.3%), L. (V.) lainsoni (4.9%), L. (Leishmania) mexicana (1%), and a putative hybrid, L. (V.) braziliensis/L. (V.) peruviana (1%). L. (V.) guyanensis was most abundant in central Peru. Of patients infected with the 3 former species, 21 (21.9%) did not respond to SbV ...
Background and objectives: Leishmaniasis is caused by the genus Leishmania. Medications such as antimony compounds for the treatment of the disease are associated with limitations along with several side effects and disease recurrence; thus, evaluation of natural compounds with history of antimicrobial properties such as Pleurotus ostreatus, is of a great importance. The purpose of this study was to evaluate the apoptotic and leishmanicidal effects of Pleurotus ostreatus alcoholic extract on Leishmania major promastigote in vitro. Methods: Different concentrations of Pleurotus ostreatus extract (50, 100, 150, 200 and 250 μg/mL) were tested at 6, 24, 48 and 72 h on Leishmania major (MRHO/IR/75/ER) promastigotes. The leishmanicidal effects were determined using MTT [3-(4,5-dimethyl thiazolyl- 2)-2,5-diphenyle tetrazolium bromide] assay. Also, apoptosis induction was measured by flow cytometry and DNA fragmentation analysis. Results:The MTT results showed that leishmanicidal effect of Pleurotus
Mucosal leishmaniasis is a rare form of the disease, that affects only 6% of the patients with cutaneous leishmaniasis in the New World. It causes deformities and may be lethal if not treated. It is part of the neglected tropical diseases because on the past sixty years there was few progress regarding other treatment options or improvement at quality of life of its patients. Also, there was little interest from the pharmaceutical industry and government authorities to develop new researches. The standard treatment, meglumine antimoniate, is toxic, invasive, requires trained personnel and has many adverse effects and restrictions. On the other hand, miltefosine is the first oral drug to demonstrate efficacy against mucocutaneous leishmaniasis. Few clinical trials have being performed in Central and South American countries, but so far, just one involved mucosal leishmaniasis patients, and compared miltefosine to amphotericin B. None studies comparing its efficacy to the standard treatment have ...
