Thermodynamic analysis of halide binding to haloalkane dehalogenase suggests the occurrence of large conformational changes. (1/418)

Haloalkane dehalogenase (DhlA) hydrolyzes short-chain haloalkanes to produce the corresponding alcohols and halide ions. Release of the halide ion from the active-site cavity can proceed via a two-step and a three-step route, which both contain slow enzyme isomerization steps. Thermodynamic analysis of bromide binding and release showed that the slow unimolecular isomerization steps in the three-step bromide export route have considerably larger transition state enthalpies and entropies than those in the other route. This suggests that the three-step route involves different and perhaps larger conformational changes than the two-step export route. We propose that the three-step halide export route starts with conformational changes that result in a more open configuration of the active site from which the halide ion can readily escape. In addition, we suggest that the two-step route for halide release involves the transfer of the halide ion from the halide-binding site in the cavity to a binding site somewhere at the protein surface, where a so-called collision complex is formed in which the halide ion is only weakly bound. No large structural rearrangements are necessary for this latter process.  (+info)

Chloride dependence of hyperpolarization-activated chloride channel gates. (2/418)

1. ClC proteins are a class of voltage-dependent Cl- channels with several members mutated in human diseases. The prototype ClC-0 Torpedo channel is a dimeric protein; each subunit forms a pore that can gate independently from the other one. A common slower gating mechanism acts on both pores simultaneously; slow gating activates ClC-0 at hyperpolarized voltages. The ClC-2 Cl- channel is also activated by hyperpolarization, as are some ClC-1 mutants (e.g. D136G) and wild-type (WT) ClC-1 at certain pH values. 2. We studied the dependence on internal Cl- ([Cl-]i) of the hyperpolarization-activated gates of several ClC channels (WT ClC-0, ClC-0 mutant P522G, ClC-1 mutant D136G and an N-terminal deletion mutant of ClC-2), by patch clamping channels expressed in Xenopus oocytes. 3. With all these channels, reducing [Cl-]i shifted activation to more negative voltages and reduced the maximal activation at most negative voltages. 4. We also investigated the external halide dependence of WT ClC-2 using two-electrode voltage-clamp recording. Reducing external Cl- ([Cl-]o) activated ClC-2 currents. Replacing [Cl-]o by the less permeant Br- reduced channel activity and accelerated deactivation. 5. Gating of the ClC-2 mutant K566Q in normal [Cl-]o resembled that of WT ClC-2 in low [Cl-]o, i.e. channels had a considerable open probability (Po) at resting membrane potential. Substituting external Cl- by Br- or I- led to a decrease in Po. 6. The [Cl-]i dependence of the hyperpolarization-activated gates of various ClC channels suggests a similar gating mechanism, and raises the possibility that the gating charge for the hyperpolarization-activated gate is provided by Cl-. 7. The external halide dependence of hyperpolarization-activated gating of ClC-2 suggests that it is mediated or modulated by anions as in other ClC channels. In contrast to the depolarization-activated fast gates of ClC-0 and ClC-1, the absence of Cl- favours channel opening. Lysine 556 may be important for the relevant binding site.  (+info)

Human extracellular water volume can be measured using the stable isotope Na234SO4. (3/418)

The volume of human extracellular water (ECW) may be estimated from the sulfate space (SS). Although it may better approximate ECW volume than the bromide space, a common alternative, SS measurement is limited by the need to administer a radioactive substance, sodium [35S]sulfate. In this paper, we demonstrate the measurement of the SS using the stable isotope, sodium [34S]sulfate. Eight healthy nonobese men ingested 0.50-0.78 mg (3.47-5.42 micromol) Na234SO4/kg body weight and 30 mg NaBr/kg body weight. Sulfate concentrations and 34SO4 enrichments were measured by electrospray tandem mass spectrometry before and during the 5 h after tracer administration. SS was calculated by linear extrapolation of the natural logarithm of serum 34SO4 concentrations obtained at h 2, 3 and 4 compared with h 3, 4 and 5. The SS obtained using values between h 3 and 5 (187 +/- 17 mL/kg) was similar to published determinations using intravenous or oral radiosulfate, and was 80% of the simultaneously measured corrected bromide space (234 +/- 10 mL/kg, P = 0.01). Oral sodium [34S]sulfate administration is a suitable technique for measuring ECW and avoids radiation exposure.  (+info)

Bromine K-edge EXAFS studies of bromide binding to bromoperoxidase from Ascophyllum nodosum. (4/418)

Bromine K-edge EXAFS studies have been carried out for bromide/peroxidase samples in Tris buffer at pH 8.

It is found that bromide does not coordinate to the vanadium centre. Rather, bromine binds covalently to carbon. A possible candidate is active site serine.  (+info)

Agonist-induced sensitization of beta-adrenoceptor signaling in neonatal rat heart: expression and catalytic activity of adenylyl cyclase. (5/418)

Agonist stimulation of neonatal cardiac beta-adrenoceptors produces heterologous sensitization of adenylyl cyclase (AC) signaling, rather than desensitization, as seen in adults. We examined the ontogenetic patterns of AC expression and activity, and evaluated isoproterenol effects on this pattern. [(3)H]Forskolin binding showed an increase in AC concentration across the period (birth to 25 days of age) in which agonist-induced sensitization is replaced by desensitization; binding affinity also increased, suggesting a shift in conformation and/or isoform. Indeed, catalytic properties of AC changed substantially with development, as evaluated by AC responses to forskolin versus Mn(2+). In contrast, there were only minor changes in the levels of mRNAs encoding the two major isoforms. Neonates given repeated isoproterenol treatment showed an enhancement of [(3)H]forskolin binding B(max) and a precocious shift to the mature affinity state and corresponding catalytic properties. Although isoproterenol caused significant increases in AC mRNAs, the effects were small and showed no isoform preference. Thus, a primary mode for ontogenetic increases in cardiac cellular responsiveness to adrenergic stimulation is the increase in AC activity attendant upon an absolute increase in the membrane concentration of AC molecules, along with changes in the catalytic properties of AC. The lack of correlation between mRNA and AC protein suggests that the primary regulatory events are post-transcriptional. The induction of AC by beta-adrenoceptor stimulation in the fetus and neonate accounts for heterologous, agonist-induced sensitization, a phenomenon that preserves cellular responses during the period of the perinatal transition.  (+info)

Evidence for de novo production of self-replicating and environmentally adapted RNA structures by bacteriophage Qbeta replicase. (6/418)

Highly purified coliphage Qbeta replicase when incubated without added template synthesizes self-replicating RNA species in an autocatalytic reaction. In this paper we offer strong evidence that this RNA production is directed by templates generated de novo during the lag phase. Contamination of the enzyme by traces of RNA templates was ruled out by the following experimental results: (1) Additional purification steps do not eliminate this RNA production. (2) The lag phase is lengthened to several hours by lowering substrate or enzyme concentration. At a nucleoside triphosphate concentration of 0.15 mM no RNA is produced although the template-directed RNA synthesis works normally. (3) Different enzyme concentrations lead to RNA species of completely different primary structure. (4) Addition of oligonucleotides or preincubation with only three nucleoside triphosphates affects the final RNA sequence. (5) Manipulation of conditions during the lag phase results in the production of RNA structures that are adapted to the particular incubation conditions applied (e.g., RNA resistant to nuclease attack or resistant to inhibitors or even RNAs "addicted to the drug," in the sense that they only replicate in the presence of a drug like acridine orange). RNA species obtained in different experiments under optimal incubation conditions show very similar fingerprint patterns, suggesting the operation of an instruction mechanism. A possible mechanism is discussed.  (+info)

Resonance raman spectra of manganese (III) tetraphenylporphin halides. (7/418)

Unique resonance Raman spectra were obtained when manganese(III) tetraphenylporphin halides in noncoordinating solvents were illuminated by laser frequencies around 500 nm. Of particular interest is the observation of a feature that is sensitive to the nature of the axial ligand. This feature disappears when the coordinating solvent pyridine is employed, and it, therefore, appears to be diagnostic of the manganese coordination number.  (+info)

Randomised controlled trial of postnatal sodium supplementation on body composition in 25 to 30 week gestational age infants. (8/418)

AIMS: To compare the effects of early and delayed sodium supplementation on body composition and body water compartments during the first two weeks of postnatal life. METHODS: Preterm infants of 25-30 weeks' gestation were stratified and randomly assigned according to gender and gestational age, to receive a sodium intake of 4 mmol/kg/day beginning either on the second day after birth or when weight loss of 6% of birthweight had been achieved. Daily sodium intake, total fluid intake, energy intake, urine volume, and urinary sodium excretion were recorded. Total body water was measured by H(2)(18)O dilution on days 1, 7, and 14, and extracellular fluid volume by sodium bromide dilution on days 1 and 14. RESULTS: Twenty four infants received early, and 22 delayed, sodium supplementation. There were no significant differences between the groups in body water compartments on day 1. In the delayed group, but not the early group, there was a significant loss of total body water during the first week (delayed -44 ml/kg, p=0. 048; early 6 ml/kg, p=0.970). By day 14 the delayed, but not the early group, also had a significant reduction in extracellular fluid volume (delayed -53 ml/kg, p=0.01; early -37 ml/kg, p=0.2). These changes resulted in a significant alteration in body composition at the end of the first week (total body weight: delayed 791 ml/kg; early 849 ml/kg, p=0.013). By day 14 there were once again no significant differences in body composition between the two groups. CONCLUSIONS: Body composition after preterm birth is influenced by the timing of introduction of routine sodium supplements. Early sodium supplementation can delay the physiological loss of body water that is part of normal postnatal adaptation. This is likely to be of particular relevance to babies with respiratory distress syndrome. A tailored approach to clinical management, delaying the introduction of routine sodium supplements until there has been postnatal loss of body water, is recommended.  (+info)

Oxidative treatment is one of the options to eliminate emerging pollutants (EPs) from drinking water or wastewater. For drinking water treatment, the ozonation technology is already implemented at many sites all around the world, so far mostly for disinfection purposes. However, in some countries such as the Netherlands surface water contains relatively high bromide concentrations, which leads upon reaction with ozone to the formation of bromate, a suspe cted carcinogen. In such a case, UV/H2O2 treatment is considered a useful alternative, despite the fact that energy requirements are substantially higher compared to treatment with ozone or O3 /H2O2. Only in recent years, the oxidative treatment of wastewat er has been investigated to not only protect our water resources, but also the ecosystem from pollution with chemicals used in our daily life. In Switzerland, the first permanent full scale plant with ozonat ion, WWTP Neugut in Dübendorf, is running since March 2014 . Its performance was ...
I came to the conclusion that adding 2ml/liter of a 5% solution of household ammonia to the salt fixer, the time is reduced to as few as 2 hours. In this recipe I also included 2g/l of Potassium Bromide which also contributes to the speeding of the salt fixer. But it may be left away, if time may be longer than 2 hours, let us say 4 hours. Also Potassium Bromide is not a household stuff and this is actually the aim of the thing, no need of expensive products and hard to get ...

Cytochrome bo forms complexes with chloride, bromide and iodide in which haem o remains high-spin and in which the 630 nm charge-transfer band is red-shifted by 7-8 nm. The chloride and bromide complexes each have a characteristic set of integer-spin EPR signals arising from spin coupling between haem o and CuB. The rate and extent of chloride binding decreases as the pH increases from 5.5 to 8.5. At pH 5.5 the dissociation constant for chloride is 2 mM and the first-order rate constant for dissociation is 2×10-4 s-1. The order of rate of binding, and of affinity, at pH 5.5 is chloride (1) , bromide (0.3) , iodide (0.1). It is suggested that the halides bind in the binuclear site but, unlike fluoride, they are not direct ligands of the iron of haem o. In addition, both the stability of the halide complexes and the rate of halide binding seem to be increased by the co-binding of a proton.. ...

Solid samples can be prepared in a variety of ways. One common method is to crush the sample with an oily mulling agent (usually Nujol) in a marble oragate mortar, with a pestle. A thin film of the mull is smeared onto salt plates and measured. The second method is to grind a quantity of the sample with a specially purified salt (usually potassium bromide) finely (to remove scattering effects from large crystals). This powder mixture is then pressed in a mechanical press to form a translucent pellet through which the beam of the spectrometer can pass. A third technique is the cast film technique, which is used mainly for polymeric materials. The sample is first dissolved in a suitable, non hygroscopic solvent. A drop of this solution is deposited on surface of KBr or NaCl cell. The solution is then evaporated to dryness and the film formed on the cell is analysed directly. Care is important to ensure that the film is not too thick otherwise light cannot pass through. This technique is suitable ...

For the next test Ive choosen a more delicate subject with a rather big contrast due to the strong side light and a dark surrounding. I didnt care for an EI 400 exposure but started with EI 800 going up to EI 3200. Development was 80 minutes in Caffenol-C-L with 1.2 g/l potassium bromide, 5 mins presoak , 24 °C pure stand development and agitation only for the first minute. Yes, 80 mins @ 24 °C! To keep the temperature I used a mantle bath with water of the same temperature. The stronger development should give the best film speed and more contrast, and the lack of any agitation after the first minute should avoid burnt highlights. When I took the wet negs out of the tank for drying I immediately knew: yep, thats it! The EI 800 exposure is spot on, almost no postprocessing needed, the grain is very fine for EI 800 and the contrast is simply perfect. No blown highlights at all. Base fog is still low enough for easy to enlarge wetprints, perfect even development. I was amazed. Rarely Ive ...

By: Jill Enfield. People usually think of doing tintypes in large format cameras such as 4 x 5 or 8 x 10s, but for years I have been encouraging students to use any type of camera they have on hand. Brownies and pinhole cameras have been used as well as something that has become a favorite - the Holga.. Dry plate tintypes are not faux tintypes. Gelatin emulsion tintypes were made commercially (by Kodak and others) as early as the 1880s. They were also made on paper and used in street cameras.. The emulsion bought today (such as AG plus) is similar to what you get when you make it from scratch using: gelatin, silver nitrate, potassium bromide and chrome alum.. I have been using dry plate tintype kits made by Rockland called the Rockloid AG Plus Tintype Parlor. It is very simple and the plates, which are actually aluminum, can be cut with a scissors so that they can fit into any camera. Since it is dry plate, no preparation needs to be done to the camera. Nothing will be dripped on or get ruined ...
I just got home from visiting with him and speaking to the vet. Gio is completely doped up, so was mostly unresponsive when I was there. But I got to give him lots of hugs and kisses at least. He has to stay overnight, and possibly tomorrow night as well. Lots of fluids, and depending how he is tomorrow morning, maybe some other treatment whose name has slipped my mind at the moment. Something about giving IV solution that competes with the Potassium Bromide and flushes it from the system quicker. So far, he doesnt need that, but if he doesnt improve much by tomorrow morning then it is a possibility ...

Reaction mechanism - Reaction mechanism - Unimolecular: Unimolecular nucleophilic substitution reactions proceed by a two-stage mechanism in which heterolysis precedes reaction with the nucleophile. The following equation is a typical example: in which the symbols are the same as in earlier equations, with the addition of delta plus (δ+) and delta minus (δ−), which indicate partial positive and negative charges, respectively. The significant consideration in this reaction mechanism is the initial separation of the bromide ion (by way of a transition state showing partial separation of the ion) to give a free positively charged organic ion (carbonium ion). This step is the rate-determining step of the reaction,

A halide is a binary phase, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound. The alkali metals combine directly with halogens under appropriate conditions forming halides of the general formula, MX (X = F, Cl, Br or I). Many salts are halides; the hal- syllable in halide and halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. A halide ion is a halogen atom bearing a negative charge. The halide anions are fluoride (F−), chloride (Cl−), bromide (Br−), iodide (I−) and astatide (At−). Such ions are present in all ionic halide salts. Halide minerals contain halides. All these halides are colourless, high melting crystalline solids having high negative enthalpies of formation. ...

Autori: M. Teodorescu,S. G. Gaynor and K. Matyjaszewski. Editorial: American Chemical Society, Macromolecules, 33(7), p.2335-2339, 2000.. Rezumat:. Halide anions have been used as complexing ligands in iron-mediated ATRP, in both direct and reverse ATRP. In direct ATRP, iron(II) bromide complexed with ammonium and phosphonium chloride, bromide or iodide salts has been shown to catalyze the polymerization of both styrene and (meth)acrylates in a controlled manner under appropriate conditions. The experimental molecular weights increased linearly with monomer conversion and were close to the calculated values. The polymerization rates and polydispersities (Mw/Mn = 1.1 - 1.4) were dependent on the monomer employed. Reverse ATRP, initiated by AIBN/FeBr3/onium salts, led to a controlled polymerization of both methyl methacrylate and methyl acrylate, while for styrene uncontrolled molecular weights and high polydispersities were obtained, presumably due to the involvement of the cationic ...

Examples of nucleophiles are anions such as Cl−, or a compound with a lone pair of electrons such as NH3 (ammonia).. In the example below, the oxygen of the hydroxide ion donates an electron pair to bond with the carbon at the end of the bromopropane molecule. The bond between the carbon and the bromine then undergoes heterolytic fission, with the bromine atom taking the donated electron and becoming the bromide ion (Br−), because a SN2 reaction occurs by backside attack. This means that the hydroxide ion attacks the carbon atom from the other side, exactly opposite the bromine ion. Because of this backside attack, SN2 reactions result in a reversal of the configuration of the electrophile. If the electrophile is chiral, it typically maintains its chirality, though the SN2 products configuration is flipped as compared to that of the original electrophile.. ...
Relative densities and heat capacity ratios have been measured for selected aqueous systems. These measurements have been used to calculate apparent molar volumes and heat capacities. Densities of aqueous sodium bromide have been measured from 374 to 522 K and 10.00 to 30.00 MPa using a recently developed high temperature and pressure vibrating tube densimeter. These data have been used to test the utility of an automated high temperature and pressure densimetric data analysis program. Apparent molar volumes and heat capacities of several aqueous rare earth sulphate systems at 298.15 K and 0.10 MPa have been reported, and discussed in terms of ionic contributions. Single ion partial molar volumes and heat capacities for aqueous trivalent rare earth species have been estimated in a review of apparent molar data from the literature and through the use of semi-empirical Debye-Huckel equation. These singles ion properties have subsequently been used to estimate the single ion properties of the ...

For the rest of the problem, you can see that from all of the balanced equations, for every 8NaBr to be produced, 3Fe is needed. You can then start with the dimensional analysis. First convert the ton of NaBr to grams, then use molar mass to get the number of moles in 2.5ton of NaBr. Then you can use the ratio of NaBr to Fe to get the moles of Fe. From there, you could use molar mass and unit conversion to calculate and convert the final mass of Fe needed. Hope this helped ...

Hi all -- Ive spoken with Mike about his bromine request. The OSHA PEL (TWA) is 0.1 ppm - compare to that of Cl2, which is 0.5 ppm. However, like most things, it can be managed safely (gee, I remember using it as an undergrad in organic synthesis lab.) Its heavy, red gas, so you can see it coming. But I really dont want to see this in our cleanroom. However, Mike has worked with it and is familiar with safety precautions. This is expected to be done only a few times at most as his company is building their lab now. I would like to suggest that we allow Mike (and only Mike) to do this etch in one of the exhausted benches in the wafersaw room. His solution is pretty dilute, so he can collect the waste as solvent waste. He just needs to make sure that the bromine kept in the proper storage area, not at the bench. I would also suggest that this be done only during working hours (so people will be nearby and he can access the storage area -- I dont think we should store this in the personal ...

  • Bromide compounds, especially potassium bromide, were frequently used as sedatives in the 19th and early 20th centuries. (
  • silver bromide is extensively used in photography, and the bromides of sodium and potassium are used as drugs. (
  • Potassium bromide, commonly abbreviated as "KBr", is a drug that is commonly used to control seizures in dogs. (
  • So the potassium bromide blood level must be monitored carefully when used for treatment. (
  • A potassium bromide level is indicated after trying a new dose of potassium bromide, if excessive vomiting or diarrhea occur or if seizures develop during potassium bromide treatment. (
  • It is also a good idea to check potassium bromide blood levels at least every 6 months, even if the dog is doing well. (
  • There are no real contraindications to performing this test in an dog on potassium bromide. (
  • What Does a Potassium Bromide Level Reveal in Dogs? (
  • A potassium bromide level will reveal the levels of potassium bromide circulating in the blood. (
  • High levels of potassium bromide indicate that the dose should be reduced. (
  • Low levels indicate that the dose of potassium bromide should be increased in order to be effective. (
  • How Is a Potassium Bromide Level Done in Dogs? (
  • In order to perform a potassium bromide level, your veterinarian must draw a blood sample, which is placed in a special glass tube. (
  • Is a Potassium Bromide Level Painful to Dogs? (
  • Is Sedation or Anesthesia Needed for a Potassium Bromide Level? (
  • Potassium bromide has the same lattice structure as NaCl. (
  • The density of potassium bromide has to be calculated. (
  • Libromide comes in tablets containing 325mg of potassium bromide (KBr). (
  • The amount of salt in the dog's diet affects how much potassium bromide is in the blood stream, so blood tests are often needed to establish the correct dose for a particular dog. (
  • Side effects are seen in some dogs which are particularly sensitive to potassium bromide, or in cases of overdose. (
  • Potassium bromide (KBr) is a salt, used as an anticonvulsant and a sedative in the 1800s. (
  • Potassium bromide is a typical ionic salt which is fully dissociated and pH7 in aqueous solution. (
  • I am trying to find out which way Ethidium bromide runs in an agrose gel. (
  • A salt-induced cooperative conformational transition of a synthetic DNA, poly(dG-dC), is reversed by addition of ethidium bromide. (
  • These convenient cards stain gels easily and rapidly with a minimum of ethidium bromide waste. (
  • I have been trying to stain dead cells using ethidium bromide and I havnt been very successful. (
  • and what wave length is ideal to excite Ethidium Bromide? (
  • Ethidium bromide, also sometimes referred to as ethobromide, homidium bromide, and dromilac, appears as dark red crystals when it is pure and dry. (
  • A relatively large, flat molecule, ethidium bromide appears somewhat similar to a DNA base pair and can easily insert into strands of the material due to its chemical structure. (
  • Thus, when bound to double-stranded DNA molecules, increased fluorescence of ethidium bromide occurs. (
  • Commonly utilized in molecular biology and biochemistry laboratories around the world, ethidium is best known in its bromide form. (
  • Despite the usefulness of ethidium bromide, many other fluorescent dyes have been developed for detecting nucleic acid components in recent years. (
  • The reason for this progression is largely due to the fact that ethidium bromide use is plagued by many possible hazards. (
  • Moreover, inhalation of ethidium bromide dust could cause serious side effects since the stain is known to be a severe respiratory irritant. (
  • Hydrobromic acid is a water solution of hydrogen bromide, a gas. (
  • HOBr (aq) + HBr (g)}}} This forms hypobromous acid (HOBr), and hydrogen bromide (HBr) a colourless gas. (
  • This produces toxic gases including hydrogen bromide (see ICSC 0282) and nitrogen oxides (see ICSCs 0930 and 1311). (
  • wherein said gaseous mixture comprises hydrogen bromide and a chlorine-bearing species. (
  • wherein said gaseous mixture comprises hydrogen bromide, and at least one halogen bearing species taken from the class consisting of fluorine and chlorine. (
  • and (4) potential effect of pyridostigmine bromide in oxidative stress, addressing as subtitle the influence of pyridostigmine bromide on the superoxide-hydrogen peroxide imbalance model. (
  • The substance decomposes on heating producing toxic and corrosive fumes including hydrogen bromide and carbonyl bromide. (
  • Reacts violently with water, methanol or ethanol to form hydrogen bromide. (
  • For use as a fumigant, methyl bromide often is mixed with chloropicrin, which serves as a warning agent because of its intense odour. (
  • Death and injury caused by methyl bromide-an insecticide fumigant. (
  • The practice of fumigating imported fruit and vegetables with the highly toxic fumigant methyl bromide should be stopped immediately, and effective alternatives such as steam sterilisation should be required instead, Green Party Safe Food and Health Spokesperson Sue Kedgley says. (
  • Methyl bromide is a highly toxic fumigant and it is extremely concerning that fruit and vegetables intended for human consumption are being fumigated with it," Ms Kedgley says. (
  • New Zealand's use of the ozone-depleting gas methyl bromide has doubled despite the fact that New Zealand has signed conventions pledging to reduce use of the fumigant. (
  • The largest agricultural source of bromine in soil within the United Kingdom is probably derived from the use of bromomethane (methyl bromide) as a soil fumigant. (
  • In the replicated experiments eight fumigant treatments were evaluated each year, including the nonfumigated control and commercial standard methyl bromide plus chloropicrin mixture. (
  • In summary, Garca-Mndez stated: "Replacements for methyl bromide will require more than one fumigant component as well as a higher level of management of pest populations in the fields during rotational crop production. (
  • The North Carolina Department of Environmental Quality's Division of Air Quality is taking action on the use of methyl bromide , a toxic fumigant, in log fumigation operations. (
  • Clidinium bromide ( INN ) is an anticholinergic (specifically a muscarinic antagonist ) drug . (
  • Ipratropium Bromide Inhalation Solution is an anticholinergic (parasympatholytic) agent that, based on animal studies, appears to inhibit vagally-mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released from the vagus nerve. (
  • Ipratropium bromide , a short-acting inhaled anticholinergic, was approved in 1986 for COPD. (
  • Spiriva HandiHaler ( tiotropium bromide) Inhalation Powder is an anticholinergic drug used to prevent bronchospasm (narrowing of the airways in the lungs ) in people with bronchitis , emphysema , or COPD ( chronic obstructive pulmonary disease ). (
  • Glycopyrronium Bromide is also known as glycopyrrolate, an anticholinergic agent. (
  • Ipratropium bromide is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo[3.2.1] octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl8-(1-methylethyl)-, bromide monohydrate, (3-endo, 8-syn)-: a synthetic quaternary ammonium compound chemically related to atropine . (
  • Silver bromide is one of the light-sensitive silver salts used in films, plates, and printing papers for photography. (
  • Bromargyrite-natural, crystalline silver bromide-is the most common bromide mineral known but is still very rare. (
  • The formation of creamy silver bromide precipitate confirms the existence of bromides. (
