Exposure to trichloroethylene II. Metabolites in blood and urine. (1/52)

Fifteen men were exposed to trichloroethylene (TRI) in three different ways with regard to the concentration of TRI in the air as well as exercise on a bicycle ergometer. The total amount of TRI supplied and taken up by each person was measured. The concentrations of trichloroethanol (TCE) and trichloroacetic acid (TCA) were determined in blood and urine. In spite of large differences in uptake, there were only small differences in the concentration of TCA in blood during the day of exposure. There was a large scatter for the values of TCA in urine within each group. The concentration of TCE in arterial blood increased during exposure. Thereafter the concentrations were almost constant for 2 h and differed among the groups. These results can be interpreted as being due to balanced rates of the formation and elimination of TCE. The levels mentioned were related to the uptake of TRI. The same was found for the rate of excretion of TCE in urine when calculations were made from the morning sample obtained the day after exposure.  (+info)

Mutagenicity of chloroacetaldehyde, a possible metabolic product of 1,2-dichloroethane (ethylene dichloride), chloroethanol (ethylene chlorohydrin), vinyl chloride, and cyclophosphamide. (2/52)

We have previously described a very sensitive and efficient bacterial test designed to detect chemical carcinogens as mutagens. Chloroacetaldehyde is mutagenic in this system and is of interest because it is a possible metabolite in mammals of the large volume industrial chemicals 1,2-dichloroethane (ethylene dichloride) (3.5 billion kg/yr, U.S.) and vinyl chloride (2.5 billion kg/yr, U.S.), and of the antineoplastic agent cyclophosphamide. Chloroacetaldehyde reverts a new Salmonella bacterial tester strain (TA100). Chloroacetaldehyde is shown to be hundreds of times more effective in reversion of TA100 than is chloroethanol (ethylene chlorohydrin), a known metabolic precursor of chloroacetaldehyde and a possible metabolite of dichloroethane and vinyl chloride, or than vinyl chloride, which is itself mutagenic for TA100. Chloroethanol is shown to be activated by rat (or human) liver homogenates to a more highly mutagenic form with reversion properties similar to chloroacetaldehyde. Reversion properties of cyclophosphamide after in vitro metabolic activation suggest that chloroacetaldehyde is not the active mutagenic form of this antineoplastic drug.  (+info)

Isolation and characterization of 2,3-dichloro-1-propanol-degrading rhizobia. (3/52)

2,3-Dichloro-1-propanol is more chemically stable than its isomer, 1, 3-dichloro-2-propanol, and is therefore more difficult to degrade. The isolation of bacteria capable of complete mineralization of 2, 3-dichloro-1-propanol was successful only from enrichments at high pH. The bacteria thus isolated were found to be members of the alpha division of the Proteobacteria in the Rhizobium subdivision, most likely Agrobacterium sp. They could utilize both dihaloalcohol substrates and 2-chloropropionic acid. The growth of these strains in the presence of 2,3-dichloro-1-propanol was strongly affected by the pH and buffer strength of the medium. Under certain conditions, a ladder of four active dehalogenase bands could be visualized from this strain in activity gels. The enzyme involved in the complete mineralization of 2,3-dichloro-1-propanol was shown to have a native molecular weight of 114,000 and consisted of four subunits of similar molecular weights.  (+info)

The entry of alpha-chlorohydrin into body fluids of male rats and its effect upon the incorporation of glycerol into lipids. (4/52)

The rate of entry of alpha-chlorohydrin into rat rete testis fluid has been studied using the 14-C and 36-Cl-labelled compounds. The alpha-chlorohydrin crosses the blood-testis barrier and the concentration of radioactivity in rete testis fluid attained blood levels within 45 min. Within 3 hr of a single injection of [14-C] alpha-chlorohydrin, radioactivity was widely distributed in body fluids, and was present in the lipids of the brain, testis, epididymis and epididymal fat pads. No radioactivity was found in tissue lipids following the administration of [36-Cl] alpha-chlorohydrin, which suggests that dechlorination of this compound occurs before its incorporation. Neither a single high dose nor repeated low doses of alpha-chlorohydrin induced changes in the incorporation of [14-C] glycerol into lipids of the brain, testis, epididymis and epididymal fat pads.  (+info)

Purification and structure of the major product obtained by reaction of NADPH and NMNH with the myeloperoxidase/hydrogen peroxide/chloride system. (5/52)

The first spectrophotometric study of the reaction of the myeloperoxidase/H2O2/Cl- system with NADPH and NMNH showed that the reaction products were not the corresponding oxidized nucleotides and that modifications would take place on the nicotinamide part of the molecule [Auchere, F. & Capeillere-Blandin, C. (1999) Biochem. J. 343, 603-613]. In this report, in order to obtain more precise information on the structural modifications and mechanism of the reaction, we focus on the purification and isolation of products derived from NADPH and NMNH by RP-HPLC. Electrospray ionization mass spectra indicated that the relative height of the peaks reflected that of the natural isotopic abundance of 35Cl and 37Cl, providing evidence that the products derived from NADPH and NMNH were monochlorinated. Moreover, calculated masses revealed the 1 : 1 addition of HOCl to the molecule. Various 1D and 2D NMR experiments provided data for the assignments of the chemical shifts of protons and carbons and the coupling constants of the protons of the chlorinated nucleotides. Further NOESY experiments allowed the characterization of the spatial structure of the chlorinated product and showed that trans HOCl addition occurred at the C5=C6 carbon double bond of the nicotinamide ring, leading to a chlorohydrin.  (+info)

Mutagenic potential of bisphenol A diglycidyl ether (BADGE) and its hydrolysis-derived products in the Ames Salmonella assay. (6/52)

The mutagenicity of bisphenol A diglycidyl ether (BADGE), its first and second hydrolysis products (the diol epoxide and bis-diol of BADGE, respectively) and the bis-chlorohydrin of BADGE were investigated using the Ames Salmonella assay with strains TA98, TA100, TA1535 and TA1537. The assays were performed in the absence and presence of various concentrations of rat liver S9 fraction. The results obtained confirm the mutagenic power of BADGE in strains TA100 and TA1535 and show a positive response to the diol epoxide of BADGE in these strains, although the latter compound was approximately 10 times less potent than the former. A lack of mutagenic activity of the bis-diol of BADGE and the chlorohydrin under study is also shown. These findings suggest that BADGE and, to a much lesser extent, the diol epoxide of BADGE may constitute a genotoxic hazard, but not the bis-diol or bis-chlorohydrin of BADGE.  (+info)

Lipid analysis of human HDL and LDL by MALDI-TOF mass spectrometry and (31)P-NMR. (7/52)

The analysis of HDL and LDL is important for the further understanding of atherosclerosis because changes of the protein and lipid moieties occur under pathological conditions. Because destruction of lipids leads to the formation of well-defined products such as lysophospholipids or chlorohydrins, methods that allow their fast and reliable determination would be useful. In this study, matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) was applied for the analysis of the lipid composition of human lipoproteins. These data were compared with high resolution (31)P-NMR spectroscopy. Differences between LDL and HDL in sphingomyelin and phosphatidylcholine content could be monitored by NMR and mass spectrometry, and differences with respect to the extraction efficiency were found by MALDI-TOF MS. Additionally, treatment of LDL with hypochlorite and phospholipase A(2) resulted in marked changes (formation of chlorohydrines and lysolipids). Lysophosphatidylcholines were detectable by both methods, whereas MALDI-TOF MS failed to detect chlorohydrines of phospholipids. We conclude that MALDI-TOF MS provides rapidly a reliable lipid profile of lipoproteins. However, a previous lipid separation must be performed to detect lipid oxidation products. NMR can be directly applied, but suffers from lower sensitivity, and provides only limited information on fatty acid composition.  (+info)

The effects of alpha-chlorohydrin on the composition of rat and rabbit epididymal plasma: a possible explanation of species difference. (8/52)

The relationship between the antifertility effect of alpha-chlorohydrin and changes in composition of luminal plasma from the cauda epididymidis of rats and rabbits has been investigated. At each dose regimen studied, the fertilizing capacity of rats treated with alpha-chlorohydrin was reduced to zero. The levels of sodium, potassium, glycerylphosphorylcholine (GPC), acid phosphatase and alkaline phosphatase in epididymal plasma were not markedly affected by drug treatment. The most noticeable change was a considerable increase in the concentration of lactic dehydrogenase (LDH) at all dose levels and of glutamic-oxaloacetic transaminase (GOT) after 7 days of treatment with 8 and 16 mg/kg. The effect of cold shock on the composition of epididymal plasma showed that LDH and GOT are, at least in part, derived from spermatozoa. In contrast, alpha-chlorohydrin did not have an antifertility action in the rabbit, and the only notable change in the compositon of epididymal plasma was an increase in the level of GPC. These results provide evidence that, in the rat, alpha-chlorohydrin or a metabolite primarily exerts its antifertility effect by a direct action on the spermatozoa, whilst in the rabbit a barrier may exist to the entrance of the drug into the lumen of the epididymal duct.  (+info)

The oxidation of low-density lipoprotein (LDL) is thought to contribute to atherogenesis, which is an inflammatory disease involving activation of phagocytic cells. Myeloperoxidase, an enzyme which is able to produce hypochlorous acid (HOCl), is released from these phagocytic cells, and has been found in an active form in atherosclerotic plaques. HOCl can oxidize both the lipid and protein moiety of LDL, and HOCl-modified LDL has been found to be pro-inflammatory, although it is not known which component is responsible for this effect. As HOCl can oxidize lipids to give chlorohydrins, we hypothesized that phospholipid chlorohydrins might have toxic and pro-inflammatory effects. We have formed chlorohydrins from fatty acids (oleic, linoleic and arachidonic acids) and from phospholipids (stearoyl-oleoyl phosphatidylcholine, stearoyl-linoleoyl phosphatidylcholine and stearoyl-arachidonoyl phosphatidylcholine), and investigated various biological effects of these oxidation products. Fatty acid and ...

The major part of this thesis describes the asymmetric synthesis of β- and γ-amino alcohols through the combination of ruthenium catalyzed racemization and enzymatic kinetic resolution.. The dynamic kinetic resolution, DKR, protocol for chlorohydrins was improved by employing Bäckvalls catalyst, which is a base activated racemization catalyst, in combination with Burkholderia cepacia lipase. These optimized conditions broadened the substrate scope and improved the yields and ees of the obtained chlorohydrin acetates. The utility of the method was demonstrated in the synthesis of (S)-salbutamol.. In the second part of the thesis, DKR was utilized in the enantio-determining step of the total synthesis of (R)-duloxetine. Optimized DKR conditions, combining Bäckvalls catalyst together with Candida antarctica lipase B, afforded a β-cyano acetate in high yield and ee. (R)-Duloxetine was accessible through synthetic alterations of the enantioenriched β-cyano acetate in high overall ...

When water attacks carbon, carbon lets go of the electrons binding it to bromine. (bromine wanted them anyway) thus breaking the bromonium bridge.. The attacking oxygen atom still has 2 bound hydrogen atoms for a total of 3 bonds and one lone pair. This results in an oxonium, or an oxygen atom with a positive formal charge.. Oxygen, an electronegative atom, is not thrilled with the positive charge and therefore pulls on the electrons binding it to hydrogen. This results in a slightly less positive oxygen, and a partially positive hydrogen atom.. Another water molecule in solution reaches out with one of its nucleophilic lone pairs to grab the partially positive hydrogen atom. The electrons break away and return to the oxygen giving it a second lone pair and neutral charge.. This resulting product is a halohydrin. If bromine you get a bromohydrin, if chlorine youll get a chlorohydrin.. How Markovnikovs Rule Factors In:. Recognize that at no point in this explanation did I mention a carbocation. ...

With the purpose of improving the mechanical properties of the polyamides, the possibility of combining polyamides with elastomers has been used. The low compatibility of the resulting blends leads to deficient mechanical properties, and therefore, it is necessary to add the compatibilizer to the mixture or to produce the compatibilizer during the melting mixture. Usually, at least one of the components must contain a reactive functional groups. In the present work, blends of polyamide 6 (PA 6) and epichlorohydrin elastomers, polyepichlorohydrin (PEPI), and the equimolar copolymer poly(epichlorohydrin-co-ethylene oxide), EGO, with different compositions were prepared by mechanical mixture using a Banbury-type mixer. The blends were characterized by rheological measurements, the Molau test, elemental analysis, Infrared Spectroscopy by Diffuse Reflectance, Transmission Electron Microscopy, and X-ray Diffractometry. The blends of PA 6 with PEPI and ECO are heterogeneous, showing a morphology of ...

You could of course cheat and buy these Pukka Herbs 3 ginger teabags.

Epichlorohydrin (ECH) is a DNA bifunctional alkylating agent that has been shown to form DNA inter-strand cross-links in vitro at the N7 position of guanines at the 5-GNC and 5-GC consensus sequences. We used the quantitative polymerase chain reaction (QPCR) to monitor the formation of in vivo ECH lesions in 6C2 chicken erythroid progerutor cells. Three distinct loci were investigated in order to determine the effect of ECH reactivity in different levels of chromatin condensation. The sites consisted of an open locus of the nuclear genome, a closed locus of the nuclear genome, and a naked locus of the mitochondrial genome. We found that ECH alkylation was preferentially targeted towards the nuclear sites and that chromatin structure had no effect upon ECH reactivity. Repair assays of the three sites revealed that there appears to be no repair of ECH lesions in the nuclear genome.

Some places legally defined pi as 3, too. Theres an old story about a farmer who sees a man poking around his barn. He goes out to ask the stranger what he wants. The stranger whips out a badge and says, "Listen! Im from the state tax office and this badge means I dont have to tell you when Im going in your barn. Now Im going to go over to that shed across the field." The farmer says, "You should do that." The agent gets irate and once again waves his badge in the farmers face. "I dont NEED your permission as long as Im carrying this badge." The farmer relents.. The agent opens the gate, enters the field, and attracts the attention of the farmers old bull. The bull, enraged, starts charging at the agent who begins running and screaming for help. The farmer cups his hand to his mouth and says, "Show him the badge! Show him the badge!". So, yes, no one is arguing you cant do conversions. By the way, there is a serious byproduct of the "legal" decision to make the inch 2.54cm in 1959. The ...

How is Vinyl Made? Vinyl is essentially derived from two simple ingredients: petroleum and salt. Petroleum or natural gas is put through a process, called cracking, to make ethylene, which is combined with the natural element chlorine to produce ethylene dichloride. Another cracking process transforms ethylene dichloride into a gas called vinyl chloride monomer (VCM). Finally, through a process known as polymerization, the gaseous monomer is converted into a fine, white powder - vinyl resin. However, one more step remains before the resin becomes a usable material. Besides looking very much like flour, vinyl resin is similar to flour. Both are of little use, by themselves. However, just as flour can be combined with other ingredients to make a moist cake, a flaky pie crust, or a variety of breads, vinyl resin can achieve various desired properties suited for a variety of end-products once it is combined with selected chemical additives and modifiers. https://www.eduessayhelper.org. The diagram ...

To enhance solubility and the performance of a plant gum (from south peach tree of China, SP gum) as a drilling fluid additive, we explored the potential of Modified SP (MSP) gum by modifying it with epichlorohydrin. The modification conditions, such as the mass ratio of the crosslinking agent, pH and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslinking agent to SP gum with pH=10 at the temperature of 50°C lead to the Modified SP (MSP) gum showed the well performance in the water based drilling fluids.It was discovered that drilling fluids modified with 0.5%wt MSP demonstrated more excellent rheology and lower filtration than that of SP treated drilling fluids, which should be contributed to the good clay inhibition obtained from swelling experiment and high inhibitive to the hydration and swell of the mud supported by mud ball immersing experiments .
