Allyl-containing sulfides in garlic increase uncoupling protein content in brown adipose tissue, and noradrenaline and adrenaline secretion in rats. (1/1610)

The effects of garlic supplementation on triglyceride metabolism were investigated by measurements of the degree of thermogenesis in interscapular brown adipose tissue (IBAT), and noradrenaline and adrenaline secretion in rats fed two types of dietary fat. In Experiment 1, rats were given isoenergetic high-fat diets containing either shortening or lard with or without garlic powder supplementation (8 g/kg of diet). After 28 d feeding, body weight, plasma triglyceride levels and the weights of perirenal adipose tissue and epididymal fat pad were significantly lower in rats fed diets supplemented with garlic powder than in those fed diets without garlic powder. The content of mitochondrial protein and uncoupling protein (UCP) in IBAT, and urinary noradrenaline and adrenaline excretion were significantly greater in rats fed a lard diet with garlic powder than in those fed the same diet without garlic. Other than adrenaline secretion, differences due to garlic were significant in rats fed shortening, also. In Experiment 2, the effects of various allyl-containing sulfides present in garlic on noradrenaline and adrenaline secretion were evaluated. Administration of diallyldisulfide, diallyltrisulfide and alliin, organosulfur compounds present in garlic, significantly increased plasma noradrenaline and adrenaline concentrations, whereas the administration of disulfides without allyl residues, diallylmonosulfide and S-allyl-L-cysteine did not increase adrenaline secretion. These results suggest that in rats, allyl-containing sulfides in garlic enhance thermogenesis by increasing UCP content in IBAT, and noradrenaline and adrenaline secretion.  (+info)

Nitrate removal in closed-system aquaculture by columnar denitrification. (2/1610)

The columnar denitrification method of nitrate-nitrogen removal from high-density, closed system, salmonid aquaculture was investigated and found to be feasible. However, adequate chemical monitoring was found to be necessary for the optimization and quality control of this method. When methanol-carbon was not balanced with inlet nitrate-nitrogen, the column effluent became unsatisfactory for closed-system fish culture due to the presence of excess amounts of nitrite, ammonia, sulfide, and dissolved organic carbon. Sulfide production was also influenced by column maturity and residence time. Methane-carbon was found to be unsatisfactory as an exogenous carbon source. Endogenous carbon could not support high removal efficiencies. Freshwater columns adpated readily to an artificial seawater with a salinity of 18% without observable inhibition. Scanning electron microscopy revealed that the bacterial flora was mainly rod forms with the Peritricha (protozoa) dominating as the primary consumers. Denitrifying bacteria isolated from freshwater columns were tentatively identified as species of Pseudomonas and Alcaligenes. A pilot plant column was found to behave in a manner similar to the laboratory columns except that nitrite production was never observed.  (+info)

Dense populations of a giant sulfur bacterium in Namibian shelf sediments. (3/1610)

A previously unknown giant sulfur bacterium is abundant in sediments underlying the oxygen minimum zone of the Benguela Current upwelling system. The bacterium has a spherical cell that exceeds by up to 100-fold the biovolume of the largest known prokaryotes. On the basis of 16S ribosomal DNA sequence data, these bacteria are closely related to the marine filamentous sulfur bacteria Thioploca, abundant in the upwelling area off Chile and Peru. Similar to Thioploca, the giant bacteria oxidize sulfide with nitrate that is accumulated to +info)

Tetradecylthioacetic acid (a 3-thia fatty acid) impairs secretion of oleic acid-induced triacylglycerol-rich lipoproteins in CaCo-2 cells. (4/1610)

The fatty acid analogue tetradecylthioacetic acid (TTA) has previously been shown to decrease triacylglycerol secretion in CaCo-2 cells (Gedde-Dahl et al., J. Lipid Res. 36 (1995) 535-543). The present study was designed to further elucidate the effect of TTA on lipoprotein production in CaCo-2 cells. TTA did not affect oleic acid-induced triacylglycerol synthesis, but it significantly decreased secretion of newly synthesized triacylglycerol when compared to cells incubated with oleic acid alone or oleic acid in combination with palmitic acid. In contrast, pulse-chase experiments showed no difference in the amount of labeled triacylglycerol secreted from cells exposed to either fatty acid combination during the chase period, indicating that TTA did not affect the secretory process in general. Cells incubated with TTA alone secreted triacylglycerol present at 1.025+info)

Thiolated recombinant human tumor necrosis factor-alpha protects against Plasmodium berghei K173-induced experimental cerebral malaria in mice. (5/1610)

The introduction of reactive thiol groups in recombinant human tumor necrosis factor (TNF) alpha (rhTNF-alpha) by the reagent succinimidyl-S-acetylthioacetate resulted in the formation of a chemically stabilized rhTNF-alpha trimer (rhTNFalpha-AT; as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis). rhTNFalpha-AT showed a substantially enhanced protective efficacy against the development of experimental murine cerebral malaria (ECM) after intravenous injection compared to the protective efficacy of nonmodified rhTNF-alpha. Administration of thiolated rhTNF-alpha with protected thiol groups (rhTNFalpha-ATA; no stabilized trimers in vitro) exhibited the same protective efficacy against ECM, while in vitro bioactivity was reduced. Parasitemia was significantly suppressed in rhTNF-treated mice that were protected against ECM but not in treated mice that developed ECM. Protection against ECM was not related to increased concentrations in plasma of soluble TNF receptor 1 and 2 directly after injection or at the moment of development of ECM in nontreated mice. The results indicate that thiolation of rhTNF-alpha leads to the formation of stable trimers with increased potential in vivo.  (+info)

A fission yeast gene for mitochondrial sulfide oxidation. (6/1610)

A cadmium-hypersensitive mutant of the fission yeast Schizosaccharomyces pombe was found to accumulate abnormally high levels of sulfide. The gene required for normal regulation of sulfide levels, hmt2(+), was cloned by complementation of the cadmium-hypersensitive phenotype of the mutant. Cell fractionation and immunocytochemistry indicated that HMT2 protein is localized to mitochondria. Sequence analysis revealed homology between HMT2 and sulfide dehydrogenases from photosynthetic bacteria. HMT2 protein, produced in and purified from Escherichia coli, was soluble, bound FAD, and catalyzed the reduction of quinone (coenzyme Q2) by sulfide. HMT2 activity was also detected in isolated fission yeast mitochondria. We propose that HMT2 functions as a sulfide:quinone oxidoreductase. Homologous enzymes may be widespread in higher organisms, as sulfide-oxidizing activities have been described previously in animal mitochondria, and genes of unknown function, but with similarity to hmt2(+), are present in the genomes of flies, worms, rats, mice, and humans.  (+info)

Health aspects of the curing of synthetic rubbers. (7/1610)

A commonly used tread rubber formulation was cured in the laboratory under conditions simulating vulcanization in the Bag-O-Matic press. Volatile emissions were collected on charcoal and analyzed by combined GC-mass spectrometry. The compounds identified were either contaminants present in the raw material or reaction products. Some of these compounds were also identified in charcoal tube samples collected in the atmosphere of the industrial operations. Estimates based on the loss of weight of rubber during curing were used to predict airborne concentrations and compared to the concentrations actually found. The literature of the toxicity of raw materials and effluents was reviewed, and no acute or chronic toxicological effects would be anticipated. Information concerning potential carcinogenicity was not available and could not be evaluated.  (+info)

Novel derivatives of phenethyl-5-bromopyridylthiourea and dihydroalkoxybenzyloxopyrimidine are dual-function spermicides with potent anti-human immunodeficiency virus activity. (8/1610)

Sexually active women represent the fastest growing HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome) risk group. In an effort to develop a vaginal microbicidal contraceptive potentially capable of preventing HIV transmission as well as providing fertility control, we have synthesized novel non-nucleoside inhibitors (NNIs) of HIV-1 reverse transcriptase (RT) and examined them for dual-function anti-HIV and spermicidal activity. Structure-based drug design by use of a computer docking procedure for the NNI binding pocket generated from nine RT-NNI crystal structures led to the synthesis of three novel NNIs: N-[2-(2, 5-dimethoxyphenethyl)]-N'-[2-(5-bromopyridyl)]-thiourea (D-PBT); N-[2-(2-fluorophenethyl)]-N'-[2-(5-bromopyridyl)]-thiourea (F-PBT); and 5-isopropyl-2-[(methylthiomethyl)thio]-6-(benzyl)-pyrimidin-4-(1H)-on e (S-DABO). The anti-HIV activity of these NNIs was compared with that of trovirdine and virucidal/spermicide, nonoxynol-9 (N-9), by measuring viral RT activity and p24 antigen production as markers of viral replication using HTLVIIIB-infected human peripheral blood mononuclear cells (PBMCs). The effects on sperm motion kinematics and sperm membrane integrity were examined by computer-assisted sperm analysis and by confocal laser scanning microscopy (CLSM), respectively. The growth-inhibitory effects of NNI versus N-9 against normal human ectocervical and endocervical epithelial cells were tested using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay. All three NNIs were potent inhibitors of purified recombinant HIV RT and abrogated HIV replication in PBMCs at nanomolar concentrations (IC50 < 1 nM) when compared with N-9 or trovirdine (IC50 values of 2.2 microM and 0.007 microM, respectively). Two NNIs, F-PBT and S-DABO, also exhibited concentration- and time-dependent spermicidal activity. The drug concentration required to inhibit sperm motility by 50% (EC50 values) for the lead compound F-PBT versus N-9 was 147 microM and 81 microM, respectively. Sperm-immobilizing activity induced by F-PBT and S-DABO was rapid (t1/2 = 7-13 min) and irreversible. Unlike that of N-9, spermicidal activity of F-PBT and S-DABO was not accompanied by loss of acrosomal membrane as detected by fluorescent-lectin binding assay and CLSM. Whereas N-9 was cytotoxic to normal human ectocervical and endocervical cells at spermicidal doses, both F-PBT and S-DABO were selectively spermicidal. We conclude that as potent anti-HIV agents with spermicidal activity and reduced cytotoxicity, F-PBT and S-DABO show unique clinical potential to become the active ingredients of a vaginal contraceptive for women who are at high risk for acquiring HIV by heterosexual vaginal transmission.  (+info)

Dimethyl trisulfide - WikipediaDimethyl trisulfide - Wikipedia
Dimethyl trisulfide (DMTS) is an organic chemical compound and the simplest organic trisulfide. It is a flammable liquid with a foul odor, which is detectable at levels as low as 1 part per trillion. Dimethyl trisulfide has been found in volatiles emitted from cooked onion, leek and other Allium species, from broccoli and cabbage, as well as from Limburger cheese, and is involved in the unpalatable aroma of aged beer and stale Japanese sake. It is a decomposition product of bacterial decomposition, including the early stages of human decomposition, and is a major attractant for blowflies looking for hosts. Dimethyl trisulfide along with dimethyl sulfide and dimethyl disulfide have been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum (Helicodiceros muscivorus). These flies are attracted to the odor of fetid meat and help pollinate this plant. DMTS contributes to the foul odor given off by the fungus Phallus impudicus, also known as the common ...

The thermodynamics for the first electron transfer step for sulfide and oxygen indicates that the reaction is unfavorable as unstable superoxide and bisulfide radical ions would need to be produced. However, a two electron transfer is favorable as stable S(0) and peroxide would be formed, but the partially filled orbitals in oxygen that accept electrons prevent rapid kinetics. Abiotic sulfide oxidation kinetics improve when reduced iron and/or manganese are oxidized by oxygen to form oxidized metals which in turn oxidize sulfide. Biological sulfur oxidation relies on enzymes that have evolved to overcome these kinetic constraints to affect rapid sulfide oxidation. Here we review the available thermodynamic and kinetic data for H2S and HSā€¢ as well as O2, reactive oxygen species, nitrate, nitrite and NOx species. We also present new kinetic data for abiotic sulfide oxidation with oxygen in trace metal clean solutions that constrain abiotic rates of sulfide oxidation in metal free solution and agree with

With the development of science and technology, new applications about nanoparticles should be explored to achieve full-scale knowledge. Therefore, in this work, the toxicity and potential application of raw cadmium sulfide nanoparticles (CdS) in vivo were further studied through ICP-OES and CTs. Surprisingly, CdS exhibited an excellent photographic property, except for finding the accumulation of CdS in the lungs, liver, spleen, and kidney with a strong dependence on time; it is also found that there were a significant uptake in the pancreas for an obvious CT imaging. And the following investigations showed that the raw CdS could damage the tissues accumulating nanoparticles. Through this work, it can be seen that the raw CdS being modified might be an excellent photographic developer for detecting cancers or other diseases.

Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately choosing the composition of the sulfide host. Main application areas are flat panel displays based on thin film electroluminescence, field emission displays and ZnS-based powder electroluminescence for backlights. For these applications, special attention is given to BaAl2S4:Eu, ZnS:Mn and ZnS:Cu. Recently, sulfide materials have regained interest due to their ability (in contrast to oxide materials) to provide a broad band, Eu2+-based red emission for use as a color conversion material in white-light emitting diodes (LEDs). The potential application of rare-earth doped binary alkaline-earth sulfides, like CaS and SrS, thiogallates, thioaluminates and thiosilicates as conversion phosphors is discussed. Finally, this review concludes with the size

AU - Wang, Weilin. AU - Wei, Boli. AU - Oyama, S. Ted. AU - Schwartz, Viviane. PY - 2003/3. Y1 - 2003/3. N2 - Molybdenum based sulfide catalysts are widely used in hydroprocessing of petroleum fractions in refining industry. Multi-probe molecular reactions for simultaneous HDS, HDN, and C-C hydrogenolysis over Mo-based monometallic and bimetallic carbide and sulfide catalysts, in conjunction with the work on single-probe molecular reactions were presented. A multi-component model-feedstock was used to test catalytic functions. These reactions were precisely those involved in the conversion and processing of heavy hydrocarbon resources such as heavy oil, coal, and other residual materials. The multi-component feed includes 4-(1-naphthylmethyl)bibenzyl, dibenzothiophene, quinoline, pyrene, and eicosane. ...

Frank: Thank you for the comment. It is hard to answer your question because GTAC has not been very forthcoming about what its plans actually are. There are two end-members of a range of possibilities. At one end, it is possible that everything GTAC has said is true, that it has not looked at the cores, that it has no idea what is in they Tyler shale, and that this is an iron mine pure and simple. In that case the mine will uncover pyrite and apatite in the process of recovering the iron, which is a problem that has not been discussed at all by either by GTAC or the legislators. The whole rationale for creating separate laws to cover the mining of iron oxides is that iron oxide mining will not uncover sulfides. The presence of sulfides in the Tyler undermines this rationale. At the other extreme is the possibility that GTAC knows exactly what is in the Tyler and is hiding it, either to prevent the issue of sulfides being raised during debate over a bill that creates an artificial distinction ...

Family of Minerals
The six families we will investigate include the sulfides, sulfates, oxides, halides, carbonates, borates, and silicates. Sulfides and sulfates all have sulfur in the anion. For example galena is a sulfide and its composition is PbS. The sulfides mainly are metallic. The sulfates include the radical SO4 and include minerals that are nonmetallic. These can include gypsum. Some families have an anion that is related to oxygen. Oxides contain a anion that is usually a metal in combination with oxygen. For example, hematite is iron plus oxygen (Fe2O3). Carbonates include the CO3 radical and includes minerals like calcite. Borates contain the BO3 group and include minerals like borax and ulexite. Sulfates also have oxygen within its radical.. Silicates form the largest chemical class among the minerals. They contain various elements in different combination like sodium, potassium, calcium, magnesium, aluminum, and iron in combination with silicon and oxygen. They have very complex chemical structures. ...

The study procedure was based on OECD Guideline No. 218 (2004). The batch of TPS 32 (polysulfides, di-tert-dodecyl) tested was a clear yellow liquid. Based on the results of the range-finding test, a final test was performed with concentrations ranging from 100 to 1000 mg/kg d.w., increasing with a factor of 1.8. Furthermore, a blank-control and a solvent-control were included. The test concentrations were prepared by mixing spiked sand, after evaporation of the solvent, with sediment. A bulk amount was prepared and distributed over the replicates. In total 80 larvae per group (20 per replicate/4 replicates) were exposed to the controls (blank and solvent-control) and theTPS 32 (polysulfides, di-tert-dodecyl) concentrations. The total test period was 28 days. On days 0 and 28 samples for analysis were taken from overlying water, pore water and sediment from the concentrations. The results of analysis at the start and at the end of the final test showed that the measured concentrations in ...

Patente US4678584 - Method of removing heavy metal from wastewater streams - Google PatentesPatente US4678584 - Method of removing heavy metal from wastewater streams - Google Patentes
A method for treating a heavy metal-containing liquid, such as a wastewater stream, oil for recycling, or other metal-bearing liquid, with a trithiocarbonate, particularly an alkali metal trithiocarbonate, such as sodium trithiocarbonate, to precipitate the metals as insoluble sulfides. The precipitated metal sulfides are recovered as a low volume sludge, which can be processed through standard metallurgical techniques to yield the metals in economically useful forms. Among the most unexpected results produced by this method is the lowering of the selenium content in a naturally occurring body of water from 1.0 ppm to 0.0015 ppm.

GRATONITE (Lead Arsenic Sulfide)GRATONITE (Lead Arsenic Sulfide)
Gratonite is a rare lead sulfide mineral. It forms nice crystals that can be arranged into rosette-like clusters with projecting rhombohedral terminations. Clusters can be attractive and good specimens command large prices, mostly because of the rarity of the mineral. Gratonite is a sulfosalt, a segment of sulfides where the arsenic acts more like a metal than a non-metal and occupies a position where it is bonded to sulfurs. Also, Gratonite is the most common mineral whose symmetry is in the Trigonal Pyramidal Class. ...

Diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS) are major oil-soluble organosulfur compounds of garlic responsible for most of its pharmacological effects. The present study investigated the influence of repeated intraperitoneally (ip) administration of DAS, DADS and DATS on the total level of sulfane sulfur, bound sulfur (S-sulfhydration) and hydrogen sulfide (H2S) and on the activity of enzymes, which catalyze sulfane sulfur formation and transfer from a donor to an acceptor in the normal mouse kidney, i.e., Ī³-cystathionase (CSE) and rhodanese (TST). The activity of aldehyde dehydrogenase (ALDH), which is a redox-sensitive protein, containing an -SH group in its catalytic center, was also determined. The obtained results indicated that all tested compounds significantly increased the activity of TST. Moreover, DADS and DATS increased the total sulfane sulfur level and CSE activity in the normal mouse kidney. ALDH activity was inhibited in the kidney after DATS

Signaling effects of sodium hydrosulfide in healthy donor peripheral blood mononuclear cellsSignaling effects of sodium hydrosulfide in healthy donor peripheral blood mononuclear cells
Hydrogen sulfide (H2S) is an endogenous gasotransmitter in human physiology and inflammatory disease, however, with limited knowledge of how signal transduction pathways are involved in immune cells. To examine the effects of sulfide on relevant intracellular signaling in human peripheral blood mononuclear cells (PBMCs), we stimulated healthy donor PBMCs with sodium hydrosulfide (NaHS, 1-1000 Ī¼M) to mimic H2S stimulation, and analyzed phosphorylation of p38 mitogen activated protein kinase (MAPK) (pT180/pY182), NF-ĪŗB p65 (pS529), Akt (pS473) and CREB/ATF1 (pS133/pS63) with flow and mass cytometry. In contrast to transient effects in subsets of lymphocytes, classical monocytes demonstrated sustained phosphorylation of p38, Akt and CREB/ATF1. NaHS induced calcium dependent phosphorylation of p38, Akt and CREB, but not NF-ĪŗB, and the phosphorylation of Akt was partly dependent on p38, indicative of p38-Akt crosstalk. Attenuation of these effects by molecules targeting p38 and Hsp90 indicated ...

Removal of Pb(II) and Cu(II) Ions from ā€ŽAqueous Solutions by Cadmium Sulfide ā€ŽNanoparticlesRemoval of Pb(II) and Cu(II) Ions from ā€ŽAqueous Solutions by Cadmium Sulfide ā€ŽNanoparticles
In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the metal ions at the optimum conditions. The adsorption process was rapid, as equilibrium was achieved within 15 min. The kinetic and isotherm experiment data could be well described with the pseudo-second order kinetic model and the Freundlich isotherm model. The maximum adsorption capacities for Pb(II) and Cu(II) ions were 200 mg/g and 166.7 mg/g, respectively. The thermodynamics of adsorption process such as changes in standard free energy, enthalpy and entropy were also discussed. This study revealed that CdS NPs are effective adsorbent for rapid removal of Pb(II) and Cu(II) ions from aqueous solutions.

Large sulfur isotope fractionation by bacterial sulfide oxidation | Science AdvancesLarge sulfur isotope fractionation by bacterial sulfide oxidation | Science Advances
The large sulfur isotope fractionations are best explained by a combination of mechanisms. First, a pH-dependent isotope effect can partially explain the observation with DA. It has been shown that the light [sulfur-32 (32S)] and heavy (34S) isotopes of sulfur quickly exchange between the two major sulfide species, dihydrogen sulfide (H2S) and monohydrogen sulfide (HSāˆ’), in the pH range of the experiment and reach an isotope equilibrium where H2S is +6ā€° enriched relative to HSāˆ’ (12, 13). Since MSO uses H2S as a substrate as opposed to HSāˆ’ (14), the relative speciation of sulfide, which is pH dependent [pKa (where Ka is the acid dissociation constant) = 6.89], will have an important consequence on the resulting sulfur isotope enrichment. For example, at pH 7 where H2S accounts for 50% of the sulfide, phototrophic sulfide oxidizers consume H2S and produce elemental sulfur (S0). The H2S is +6ā€° enriched in 34S relative to HSāˆ’ but is only +3ā€° enriched relative to the bulk sulfide. Thus, ...

The reaction of H2O2 with thioanisole and p-methoxythioanisole catalysed by lignin peroxidase from Phanerochaete chrysosporium has been studied spectrophotometrically under turnover and single turnover conditions with a stopped-flow apparatus. Pre-formed lignin peroxidase compounds I and II are each able to react with the sulphides to form a sulphide radical cation. The radical cation is then converted into the sulphoxide either by reaction with the medium or by reaction with compound II. This is the first report of a direct reaction between compound II and the substrate radical cation. With thioanisole, significant enantiomeric selectivity and high oxygen incorporation in the sulphoxide are obtained because compound II is preferentially reduced by the enzyme-bound thioanisole radical cation compared with the neutral substrate. By contrast, with p-methoxythioanisole, the data imply formation of an intermediate ternary complex comprising compound II, radical cation and neutral substrate, such ...

Synthesis of Aryl Thioethers Through the NCS-Promoted Cross-Coupling Reaction of Thiols with Grignard Reagents | NCHU...
A convenient one-pot approach for the synthesis of aryl sulfides through the coupling of thiols with Grignard reagents in the presence of N-chlorosuccinimide is described. The sulfenylchlorides were formed when thiols were treated with N-chlorosuccinimide, and the resulting sulfenylchlorides were then directly reacted with Grignard reagents to provide aryl sulfides in good to excellent yields under mild reaction conditions. Functional groups including ester, fluoro and chloro are tolerated by the reaction conditions employed. It is important to note that this method has a short reaction time (30 min in total), and represents an alternative approach for the synthesis of aryl sulfides over the existing protocols ...

ABSTRACT: The ecophysiological differences of 4 sibling species of the Capitella capitata species complex from habitats with different sulfide concentrations were studied: Capitella sp. S (small) from a North Sea intertidal flat, living in the upper sediment layer containing low sulfide concentrations (up to 20 Āµmol l-1); Capitella sp. L (large), sympatric to Capitella sp. S, but living in deeper sediment layers with high sulfide concentrations (up to 350 Āµmol l-1); Capitella sp. M from the Mediterranean Sea from highly sulfidic sediments (up to 710 Āµmol l-1) close to shallow hydrothermal vents; and Capitella sp. I from eutrophicated coastal areas of the North Atlantic. Capitella sp. L, Capitella sp. M and Capitella sp. I are significantly more tolerant to anoxia and 760 Āµmol l-1 sulfide than Capitella sp. S from the upper North Sea sediments. Respiration rates showed that only Capitella sp. S can be characterized as an oxyconformer. The oxygen consumption of Capitella sp. S becomes ...

Hydrothermal sulfide chimneys located along the global system of oceanic spreading centers are habitats for microbial life during active venting. Hydrothermally extinct, or inactive, sulfide deposits also host microbial communities at globally distributed sites. The main goal of this study is to describe sulfide mineral alteration at the seafloor, and examine alteration products for signatures of biological activity using Fe mineralogy and stable isotope approaches. The study includes active and inactive sulfides from the East Pacific Rise 9o50N vent field. First, the mineralogy of Fe(III)-bearing precipitates is investigated using microprobe X-ray absorption spectroscopy (ĀµXAS) and X-ray diffraction (ĀµXRD). Second, laser-ablation (LA) and micro-drilling (MD) are used to obtain samples for Fe stable isotopes by multicollector-inductively couple plasma-mass spectrometry (MC-ICP-MS). Eight Fe-bearing minerals types are present in the samples: oxyhydroxides, secondary phyllosilicates, and sulfides

Solvent-Free Synthesis of Quaternary Metal Sulfide Nanoparticles Derived from Thiourea - KAUST RepositorySolvent-Free Synthesis of Quaternary Metal Sulfide Nanoparticles Derived from Thiourea - KAUST Repository
The synthesis of metal sulfide (MS) materials with sizes in the sub-10 nm regime often requires capping agents with long hydrocarbon chains that affect their structures and properties. Herein, this study presents a molten-state synthesis method for a series of transition-MS nanoparticles using thiourea as a reactive precursor without capping agents. This study also reports the synthesis of MS with single metals (Fe, Co, Ni, Cu, and Zn) and quaternary CuGa2In3S8 using the same synthesis protocol. Thiourea first melts to form a molten-state condition to serve as the reaction medium at a relatively low temperature (,200 Ā°C), followed by its thermal decomposition to induce a reaction with the metal precursor to form different MS. This synthesis protocol, owing to its dynamic characteristics, involves the formation of a variety of organic carbon nitride polymeric complexes around the MS particles. Dynamic nuclear polarization surface-enhanced nuclear magnetic resonance spectroscopy is effective to ...

The changes in neurotransmitters biosynthesis in the cerebrum of Coq9R239X mice are not limited to the reduction in Lā€glutamate but also to the biosynthesis of serotonin and catecholamines. These alterations might be a consequence of the disruption in hydrogen sulfide metabolism because a doseā€dependent and timeā€dependent decrease in glutamate levels and increase in serotonin levels have been described in the cerebrum and frontal cortex of rats chronically exposed to 20 ppm and 75 ppm of hydrogen sulfide (Skrajny et al, 1992; Roth et al, 1995). The same authors reported a decrease in the levels of norepinephrine with the exposure to 20 ppm of hydrogen sulfide and an increase in those levels with the exposure to 75 ppm of hydrogen sulfide (Skrajny et al, 1992). Norepinephrine and epinephrine levels were, however, decreased in isolated porcine irisā€ciliary body exposed to increased concentrations of NaSH, which is a commonly used hydrogen sulfide donor (Kulkarni et al, 2009).

The 2nd analytical group of cations consists of ions that form acid-insoluble sulfides. Cations in the 2nd group include: Cd2+, Bi3+, Cu2+, As3+, As5+, Sb3+, Sb5+, Sn2+, Sn4+ and Hg2+. Pb2+ is usually also included here in addition to the first group. Although these methods refer to solutions that contain sulfide (S2āˆ’), these solutions actually only contain H2S and bisulfide (SHāˆ’). Sulfide (S2āˆ’) does not exist in appreciable concentrations in water. The reagent used can be any substance that gives S2āˆ’ ions in such solutions; most commonly used are H2S (at 0.2-0.3 M), AKT (at 0.3-0.6 M). The test with the sulfide ion must be conducted in the presence of dilute HCl. Its purpose is to keep the sulfide ion concentration at a required minimum, so as to allow the precipitation of 2nd group cations alone. If dilute acid is not used, the early precipitation of 4th group cations (if present in solution) may occur, thus leading to misleading results. Acids beside HCl are rarely used. Sulfuric acid ...

Rotoruas hydrogen sulphide does not worsen asthma - Healthcanal.com : Healthcanal.comRotoruas hydrogen sulphide does not worsen asthma - Healthcanal.com : Healthcanal.com
Hydrogen sulphide or H2S is responsible for the characteristic sulphur smell of Rotorua.. There has long been medical and scientific debate about the health impacts of H2S gas in the workplace and residential areas, and this study is the largest ever of associations between ambient H2S and respiratory health. Concentrations of toxic hydrogen sulphide gas can be produced in factories as a by-product of industrial processes, as well as naturally in volcanic and geothermal regions like Rotorua.. The five year study examined a variety of health effects, including asthma, amongst over 1600 adult Rotorua residents. With a population of nearly 60,000, Rotorua is the largest centre anywhere with long term exposure to hydrogen sulphide and is recognised as an ideal place to research the health effects of H2S.. Exposure to H2S was estimated from measurements taken around Rotorua in summer and winter, and then each persons exposure was estimated from where they lived and worked. H2S exposure was divided ...

Sediment was collected 10-50 cm below the seawater/sediment interface at the Kai Tak Approach Channel connected to Victoria Harbor in Hong Kong, China. Sewage and industrial effluent had been discharged there for decades until the installation of a new sewage collection system in the late 1990s. The long lasting sulfate-reducing conditions resulted in a high sulfide concentration in the sediment, where an AVS (Acid-Volatile Sulfide) of 198 Ī¼mol g-1 had been measured [8]. The pore water after centrifugation at 4,000 rpm for 15 min had a pH of 7.89 and a salinity of 2.9%.. Enrichments were prepared by adding 20 g of wet sediment (32.0% dry matter) to serum bottles containing 70 mL of sterilized seawater, purged with N2 and incubated for at least 24 h at room temperature. Potassium nitrate (1 g L-1) and sodium phosphate, monobasic (0.1 mmol L-1), were then added from sterilized stock solutions. The bottles were incubated at 28Ā°C in a water bath for 72 h.

Carbonaceous material (CM) is commonly associated with gold and sulfides in metasediment-hosted orogenic gold deposits. The role of CM in Au deposition is controversial; CM has been proposed to contribute to gold deposition by reducing Au bisulfide complexes, or by facilitating sulfidation, which destabilizes Au in bisulfide complexes with resultant Au deposition. Integration of petrographic observations, thermodynamic models, and geochemical data from metasediment-hosted orogenic gold deposits in New Zealand, Australia, Canada, and West Africa reveals genetic links between sulfides, CM, and mineralization. The results are consistent with the coexistence of CM and pyrite as a consequence of their codeposition from ore fluids, with a minor proportion of CM originally in situ in the host rocks. Au is deposited when pyrite and CM deposition decreases H2S concentration in ore fluids, destabilizing Au(HS)2- complexes. Most CM in gold deposits is deposited from CO2 and CH4 in ore fluids. These ...

SYNTHESIS OF MODELS FOR NEIGHBORING PROLINE AMIDE AND ARYL PARTICIPATION IN ELECTRON TRANSFER FROM THIOETHERSSYNTHESIS OF MODELS FOR NEIGHBORING PROLINE AMIDE AND ARYL PARTICIPATION IN ELECTRON TRANSFER FROM THIOETHERS
A series of 6-endo-(methylthio)-bicyclo[2.2.1]heptane-2-endo-proline amides was synthesized to study the neighboring proline amide participation in electron transfer from thioethers. The thioether with endo-pyrrolidine amide formed a two-center three-electron SO bond after one electron oxidation and the oxidation potential of the thioether was lowered by 530 mV and 330 mV compared to the corresponding exo-pyrrolidine amide and the primary amide analogues, respectively. The thioether with a proline methyl ester showed the oxidation potential of 410 mV higher than that of the pyrrolidine amide. The basis for this surprising result was revealed by an X-ray crystallographic structure study of the diastereomerically pure proline methyl ester which showed amide carbonyl n ā†’ methyl ester Ļ€* interaction which removes electron density from the neighboring amide which results in less effective neighboring amide participation in thioether oxidation. This accounts for the electrochemical result. A potent ...

What Is a Non-Silicate Mineral?What Is a Non-Silicate Mineral?
Carbonates are known as rock-forming minerals, while the remaining groups are often ore minerals. Calcite and dolomite are two of the most important carbonates. Pyrite is the only sulfide that commonly occurs in rocks. Sulfides are significant economic minerals that provide the main source of elements such as zinc, mercury, nickel, lead, molybdenum, copper and arsenic.. Non-silicate minerals constitute less than 10 percent of the Earths crust. Carbon is found in diamond and graphite form. The carbonates, sulfides and oxides are the most common non-silicates. A few elements exist in pure form, such as gold, silver, lead, arsenic, copper, tellurium and bismuth. Many of the non-silicates are considered economically important, particularly those that include valuable metals. Some non-silicates are valued as gems due to their beauty, color and hardness.. ...

Glacial weathering, sulfide oxidation, and global carbon cycle feedbacks | PNASGlacial weathering, sulfide oxidation, and global carbon cycle feedbacks | PNAS
Higher dissolved ion yields and higher SO4:Na and Ca:Na ratios together suggest that sulfide and carbonate dissolution rates are enhanced in association with glacial weathering. To first order, glaciation thus appears to act as a CO2 source, by maintaining total solute fluxes while shifting weathering toward reactions that release rather than consume CO2.. In principle, glacially enhanced Ca and SO4 fluxes could derive from preferential dissolution of sulfate-bearing evaporites or weathering of Ca-bearing silicates by sulfuric acid, reactions that would not act as CO2 sources. We have no a priori reason to expect that such effects dominate globally. Nonetheless, fully understanding the net effect of glaciation on the carbon cycle depends on quantifying (i) the proportion of the dissolved sulfate derived from sulfide mineral oxidation, and (ii) the extent to which this oxidative flux of protons (Eq. 4) is balanced by alkalinity generation from silicate and carbonate weathering (Eqs. 1 and 2).

7 Great Benefits of Onions - Nutrition & Health Hub7 Great Benefits of Onions - Nutrition & Health Hub
Onion belongs to the lily group of plants. The other members of this group include leeks, shallots, garlic, etc. There are over 500 species of onion such as yellow onion, green onion, white onion and much more. Each kind of variety has its own unique taste and flavor, ranging from very strong to slightly sweet.. Not only is onion being used for centuries especially in the east to add flavor to foods, but is also known for its ornamental, therapeutic and medicinal effects.. Onion contains sulfides, thiosulfonates, and sulfoxides, which produce the eye-irritating results. The thiosulfonates exhibit anti-microbial qualities that make onion quite efficient at treating infections caused by E.coli, Salmonella and Bacillus subtilis.. Studies have demonstrated that onion is quite useful in avoiding coronary artery disease and cholesterol-reducing levels. The sulfides in onion help lower blood pressure levels and fats as well. Moreover, onion makes an excellent organic dietary source of flavonoids, which ...

Quartz, phosphate, and organic matter occur as only one generation each. Authigenic clay minerals are represented by chlorite and kaolinite. The paragenetic sequence of cements is subdivided into the two pre-burial carbonates, succeeded by ten relatively early burial cements, and six late burial cements, the kaolinite being the latest of them all and potentially being of Cretaceous age.

  • Reference mass spectra and analytical correlations for 20 alkylcycloalkyl sulfides and two dicycloalkyl sulfides are presented to provide information that will facilitate the identification of sulfur compounds occurring in natural or synthetic mixtures. (cdc.gov)
  • Palme and O'Neill 2013) - sulfides are, nonetheless, very important phases because many elements have a strong affinity for sulfur. (elementsmagazine.org)
  • These sulfur-loving elements are termed 'chalcophiles' (Fig. 1), and they are concentrated in sulfide minerals. (elementsmagazine.org)
  • Hydrogen sulfide is used in preparation of other sulfur chemical compounds and can be a byproduct of industrial activities such as pulp and paper mills, manufacturing rayon, food processing, tanneries and fur processing, and oil and natural gas refineries. (wa.gov)
  • Moreover, addition of organic matter reduced seagrass rhizome biomass and increased pore water sulfide levels, lucinid tissue sulfur content, lucinid condition (expressed as flesh/shell dry weight ratio), and total lucinid biomass, while enhancement of lucinid densities reduced lucinid condition. (frontiersin.org)
  • Large sulfur isotope fractionation by bacterial sulfide oxidation. (cam.ac.uk)
  • A sulfide-oxidizing microorganism, Desulfurivibrio alkaliphilus (DA), generates a consistent enrichment of sulfur-34 (34 S) in the produced sulfate of +12.5 per mil or greater. (cam.ac.uk)
  • Since the DA-type sulfide oxidation pathway is ubiquitous in sediments, in the modern environment, and throughout Earth history, the enrichments and depletions in 34 S in sediments may be the combined result of three microbial metabolisms: microbial sulfate reduction, the disproportionation of external sulfur intermediates, and microbial sulfide oxidation. (cam.ac.uk)
  • Effectively, this means that industries that use hydrogen sulfide, such as sulfur-producing metallurgy or certain types of oil refineries that use hydrogen sulfide as an additive, will need a risk management plan in place, but that industries where hydrogen sulfide is a byproduct, such as pulping or concentrated agricultural feeding operations (CAFOs) often will not need to make a hydrogen sulfide risk management plan. (publiclab.org)
  • Since hydrogen sulfide can oxidize in the atmosphere to sulfur dioxide, which is a criteria pollutant included in the NAAQS, industrial operations who emit hydrogen sulfide above a certain threshold, called a Significant Emissions Rate (SER), will have to obtain a PSD permit. (publiclab.org)
  • It is made by melting metallic bismuth with sulfur or passing hydrogen sulfide into bismuth salt solution. (ormemoda.it)
  • As is well known, sulfur tends to form sulfides, in particular, chromium sulfides when the steel contains chromium. (elsevier.com)
  • One is in atomic sulfur state as a solid solution, and the other is in sulfide state as a precipitate. (elsevier.com)
