Comparison of two in vitro activation systems for protoxicant organophosphorous esterase inhibitors. (1/242)

In order to perform in vitro testing of esterase inhibition caused by organophosphorous (OP) protoxicants, simple, reliable methods are needed to convert protoxicants to their esterase-inhibiting forms. Incubation of parathion or chlorpyrifos with 0.05% bromine solution or uninduced rat liver microsomes (RLM) resulted in production of the corresponding oxygen analogs of these OP compounds and markedly increased esterase inhibition in SH-SY5Y human neuroblastoma cells. Neither activation system affected cell viability or the activity of AChE or NTE in the absence of OP compounds. Although parathion and chlorpyrifos were activated by RLM, bromine activation required fewer steps and produced more esterase inhibition for a given concentration of chlorpyrifos. However, RLM activation of OP protoxicants produced metabolites other than oxygen analogs and may, therefore, be more relevant as a surrogate for OP biotransformation in vivo. This methodology makes the use of intact cells for in vitro testing of esterase inhibition caused by protoxicant organophosphate compounds a viable alternative to in vivo tests.  (+info)

Reactive airways dysfunction and systemic complaints after mass exposure to bromine. (2/242)

Occasionally children are the victims of mass poisoning from an environmental contaminant that occurs due to an unexpected common point source of exposure. In many cases the contaminant is a widely used chemical generally considered to be safe. In the following case, members of a sports team visiting a community for an athletic event were exposed to chemicals while staying at a local motel. Bromine-based sanitizing agents and other chemicals such as hydrochloric acid, which were used in excess in the motel's swimming pool, may have accounted for symptoms experienced by the boy reported here and at least 16 other adolescents. Samples of pool water contained excess bromine (8.2 microg/mL; ideal pool bromine concentration is 2-4 microg/mL). Symptoms and signs attributable to bromine toxicity included irritative skin rashes; eye, nose, and throat irritation; bronchospasm; reduced exercise tolerance; fatigue; headache; gastrointestinal disturbances; and myalgias. While most of the victims recovered within a few days, the index case and several other adolescents had persistent or recurrent symptoms lasting weeks to months after the exposure.  (+info)

Identification and molecular characterization of BP75, a novel bromodomain-containing protein. (3/242)

We here describe the identification and characterization of a novel bromodomain-containing protein, the bromodomain protein of 75 kDa (BP75). Initially, we identified BP75 in a two-hybrid screening for proteins that interact with the first PDZ (acronym for post-synaptic density protein PSD-95, Drosophila discs large tumor suppressor DlgA and the tight junction protein ZO-1) domain in protein tyrosine phosphatase-BAS-like (PTP-BL). We found that BP75 is expressed ubiquitously and show that both BP75 and a PTP-BL deletion mutant consisting of the first PDZ domain are located mainly in the nucleus, although cytoplasmic localization is also evident. Full-length PTP-BL, on the contrary, is predominantly localized in the cytoplasm, although some basal nuclear staining is observed. The described molecular interaction may reflect a mechanism of coupling submembraneous signalling events and nuclear events.  (+info)

Actin filament organization is required for proper cAMP-dependent activation of CFTR. (4/242)

Previous studies have indicated a role of the actin cytoskeleton in the regulation of the cystic fibrosis transmembrane conductance regulator (CFTR) ion channel. However, the exact molecular nature of this regulation is still largely unknown. In this report human epithelial CFTR was expressed in human melanoma cells genetically devoid of the filamin homologue actin-cross-linking protein ABP-280 [ABP(-)]. cAMP stimulation of ABP(-) cells or cells genetically rescued with ABP-280 cDNA [ABP(+)] was without effect on whole cell Cl(-) currents. In ABP(-) cells expressing CFTR, cAMP was also without effect on Cl(-) conductance. In contrast, cAMP induced a 10-fold increase in the diphenylamine-2-carboxylate (DPC)-sensitive whole cell Cl(-) currents of ABP(+)/CFTR(+) cells. Further, in cells expressing both CFTR and a truncated form of ABP-280 unable to cross-link actin filaments, cAMP was also without effect on CFTR activation. Dialysis of ABP-280 or filamin through the patch pipette, however, resulted in a DPC-inhibitable increase in the whole cell currents of ABP(-)/CFTR(+) cells. At the single-channel level, protein kinase A plus ATP activated single Cl(-) channels only in excised patches from ABP(+)/CFTR(+) cells. Furthermore, filamin alone also induced Cl(-) channel activity in excised patches of ABP(-)/CFTR(+) cells. The present data indicate that an organized actin cytoskeleton is required for cAMP-dependent activation of CFTR.  (+info)

3,4-Dihydrocoumarin hydrolase with haloperoxidase activity from Acinetobacter calcoaceticus F46. (5/242)

A novel lactonohydrolase, an enzyme that catalyzes the hydrolysis of 3,4-dihydrocoumarin, was purified 375-fold to apparent homogeneity, with a 22.7% overall recovery, from Acinetobacter calcoaceticus F46, which was isolated as a fluorene-assimilating micro-organism. The molecular mass of the native enzyme, as estimated by high-performance gel-permeation chromatography, is 56 kDa, and the subunit molecular mass is 30 kDa. The enzyme specifically hydrolyzes 3,4-dihydrocoumarin, and the Km and Vmax for 3,4-dihydrocoumarin are 0.806 mM and 4760 U.mg-1, respectively. The N-terminal and internal amino acid sequences of the enzyme show high similarity to those of bacterial non-heme haloperoxidases. The enzyme exhibits brominating activity with monochlorodimedon in the presence of H2O2 and 3, 4-dihydrocoumarin or an organic acid, such as acetate and n-butyrate.  (+info)

Efficient introduction of aryl bromide functionality into proteins in vivo. (6/242)

Artificial proteins can be engineered to exhibit interesting solid state, liquid crystal or interfacial properties and may ultimately serve as important alternatives to conventional polymeric materials. The utility of protein-based materials is limited, however, by the availability of just the 20 amino acids that are normally recognized and utilized by biological systems; many desirable functional groups cannot be incorporated directly into proteins by biosynthetic means. In this study, we incorporate para-bromophenylalanine (p-Br-phe) into a model target protein, mouse dihydrofolate reductase (DHFR), by using a bacterial phenylalanyl-tRNA synthetase (PheRS) variant with relaxed substrate specificity. Coexpression of the mutant PheRS and DHFR in a phenylalanine auxotrophic Escherichia coli host strain grown in p-Br-phe-supplemented minimal medium resulted in 88% replacement of phenylalanine residues by p-Br-phe; variation in the relative amounts of phe and p-Br-phe in the medium allows control of the degree of substitution by the analog. Protein expression yields of 20-25 mg/l were obtained from cultures supplemented with p-Br-phe; this corresponds to about two-thirds of the expression levels characteristic of cultures supplemented with phe. The aryl bromide function is stable under the conditions used to purify DHFR and creates new opportunities for post-translational derivatization of brominated proteins via metal-catalyzed coupling reactions. In addition, bromination may be useful in X-ray studies of proteins via the multiwavelength anomalous diffraction (MAD) technique.  (+info)

Eosinophils generate brominating oxidants in allergen-induced asthma. (7/242)

Eosinophils promote tissue injury and contribute to the pathogenesis of allergen-triggered diseases like asthma, but the chemical basis of damage to eosinophil targets is unknown. We now demonstrate that eosinophil activation in vivo results in oxidative damage of proteins through bromination of tyrosine residues, a heretofore unrecognized pathway for covalent modification of biologic targets in human tissues. Mass spectrometric studies demonstrated that 3-bromotyrosine serves as a specific "molecular fingerprint" for proteins modified through the eosinophil peroxidase-H(2)O(2) system in the presence of plasma levels of halides. We applied a localized allergen challenge to model the effects of eosinophils and brominating oxidants in human lung injury. Endobronchial biopsy specimens from allergen-challenged lung segments of asthmatic, but not healthy control, subjects demonstrated significant enrichments in eosinophils and eosinophil peroxidase. Baseline levels of 3-bromotyrosine in bronchoalveolar lavage (BAL) proteins from mildly allergic asthmatic individuals were modestly but not statistically significantly elevated over those in control subjects. After exposure to segmental allergen challenge, lung segments of asthmatics, but not healthy control subjects, exhibited a >10-fold increase in BAL 3-bromotyrosine content, but only two- to threefold increases in 3-chlorotyrosine, a specific oxidation product formed by neutrophil- and monocyte-derived myeloperoxidase. These results identify reactive brominating species produced by eosinophils as a distinct class of oxidants formed in vivo. They also reveal eosinophil peroxidase as a potential therapeutic target for allergen-triggered inflammatory tissue injury in humans.  (+info)

Permeabilization via the P2X7 purinoreceptor reveals the presence of a Ca2+-activated Cl- conductance in the apical membrane of murine tracheal epithelial cells. (8/242)

Calcium-activated Cl(-) secretion is an important modulator of regulated ion transport in murine airway epithelium and is mediated by an unidentified Ca(2+)-stimulated Cl(-) channel. We have transfected immortalized murine tracheal epithelial cells with the cDNA encoding the permeabilizing P2X(7) purinoreceptor (P2X(7)-R) to selectively permeabilize the basolateral membrane and thereby isolate the apical membrane Ca(2+)-activated Cl(-) current. In P2X(7)-R-permeabilized cells, we have demonstrated that UTP stimulates a Cl(-) current across the apical membrane of CF and normal murine tracheal epithelial cells. The magnitude of the UTP-stimulated current was significantly greater in CF than in normal cells. Ion substitution studies demonstrated that the current exhibited a permselectivity sequence of Cl(-) > I(-) > Br(-) > gluconate(-). We have also determined a rank order of potency for putative Cl(-) channel blockers: niflumic acid > or = 5-nitro-2-(3-phenylpropylamino)benzoic acid > 4, 4'-diisothiocyanostilbene-2,2'-disulfonate > glybenclamide >> diphenlyamine-2-carboxylate, tamoxifen, and p-tetra-sulfonato-tetra-methoxy-calix[4]arene. Complete characterization of this current and the corresponding single channel properties could lead to the development of a new therapy to correct the defective airway surface liquid in cystic fibrosis patients.  (+info)

About Hydrogen & Bromine | ElestorAbout Hydrogen & Bromine | Elestor
Bromine, from ancient Greek, meaning stench, is a chemical element with symbol Br, and atomic number 35. It is a halogen.. Free bromine does not occur in nature, but occurs as colorless soluble crystalline salts, analogous to table salt. The high solubility of bromide ions has caused its accumulation in the oceans, where it is abundantly available. Commercially, the element is easily extracted from brine pools, mostly in the United States, Israel and China.. Elemental bromine is a red-brown liquid at room temperature, corrosive and toxic, with properties between those of chlorine and iodine. One of the major uses of bromine is as a water purifier/disinfectant in swimming pools and hot tubs. Another key use of bromine compounds is in the manufacturing of pharmaceuticals: Brominated substances are important ingredients of many over-the-counter and prescription drugs, including analgesics, sedatives, and antihistamines.. Elestors storage systems incorporate a number of parallel and independent ...

ACP - Observations of bromine monoxide transport in the Arctic sustained on aerosol particlesACP - Observations of bromine monoxide transport in the Arctic sustained on aerosol particles
Abstract. The return of sunlight in the polar spring leads to the production of reactive halogen species from the surface snowpack, significantly altering the chemical composition of the Arctic near-surface atmosphere and the fate of long-range transported pollutants, including mercury. Recent work has shown the initial production of reactive bromine at the Arctic surface snowpack; however, we have limited knowledge of the vertical extent of this chemistry, as well as the lifetime and possible transport of reactive bromine aloft. Here, we present bromine monoxide (BrO) and aerosol particle measurements obtained during the March 2012 BRomine Ozone Mercury EXperiment (BROMEX) near Utqiaġvik (Barrow), AK. The airborne differential optical absorption spectroscopy (DOAS) measurements provided an unprecedented level of spatial resolution, over 2 orders of magnitude greater than satellite observations and with vertical resolution unable to be achieved by satellite methods, for BrO in the Arctic.

In situ generation of bromine for micelle-assisted bromination and oxidation -- Restricted access to full textIn situ generation of bromine for micelle-assisted bromination and oxidation -- Restricted access to full text
This paper describes our recent work in which CTAB (cetyltrimethylammonium bromide) micelles are used as catalytic platforms for performing bromination and oxidation reactions in water. The bromide counter ion is used to prepare Br2 in situ which is subsequently employed as a brominating and oxidizing agent. In this process the bromide is rapidly oxidized to bromine using BPO (benzoic peroxyanhydride). The reaction is facilitated by the micelle which improves the BPO solubility and its proximity with Br-. Several example reactions are discussed including micelle-assisted bromination of cholesterol and methyl styrene along with an example of mild oxidation of benzyl alcohol to form benzaldehyde. These examples illustrate the use of bromine as a mild oxidizing agent and also as a brominating agent. Kinetic studies of Br2 formation and cholesterol bromination are also presented ...

In solid substances used as fuels, bromine originates mainly from flame retarded plastics and textiles, as well as from wastewater sludge. It has been indicated that bromine behaves in a similar way as chlorine with respect to ash forming matter, aerosol formation and high temperature corrosion in biomass and waste fired boilers. In this work, a measurement campaign was carried out in a 20 kW(th) bubbling fluidized bed (BFB) bench scale reactor to characterize the fate of Cl and Br in BFB combustion conditions. Spruce bark was used as the base fuel -serving as a source of alkali metals (mainly K, little Na). The gases HCl and HBr were fed with the fluidization air at different proportions into the BFB unit. In total, six experiments were done. The fate of bromine and chlorine was evaluated by means of several measurements including: FTIR (flue gas measurement), a low-pressure impactor (size distribution and chemical composition of aerosol particles) and deposit probe sampling (deposit growth ...

Human Metabolome Database: Showing metabocard for Bromide (HMDB0002500)Human Metabolome Database: Showing metabocard for Bromide (HMDB0002500)
Bromine is a brown or red liquid with a characteristic odor. Bromine is mainly used in the manufacture of dyes, inks, flame retardants, pharmaceuticals and chemical warfare agents. Occupational exposure to bromine may occur during the production and the application of bromine compounds and during other industrial activities. This compound is adsorbed into the human body through the respiratory tract, skin (occupational exposure) and alimentary tract (general population). Physiologically, bromine exists as an ion in the body. Slight eye irritation occurs as a consequence of chronic exposure to bromine vapors at concentration of 1 mg/m3. Higher concentrations increase this effect and cause nasal and skin irritation. Many years observations have shown that during occupational exposure to bromine vapors at concentrations of up to 0.7 mg/m3 (0.1 ppm), there are no observed adverse effects. From cytotoxicity and mutagenicity assays, it is known that brominated organic compounds are more toxic than ...

Bromination of Alkenes - How Does It Work? - Master Organic ChemistryBromination of Alkenes - How Does It Work? - Master Organic Chemistry
In a previous post we went through the key reactions of the carbocation pathway. Its a family of reactions which proceed through 1) attack of an alkene upon an acid, forming a free carbocation, and 2) attack of a nucleophile upon the carbocation.. Although we saw that several key reactions of alkenes were consistent with this mechanism, it isnt the case for all. Take the bromination of alkenes, for instance.. Treatment of an alkene with bromine (Br2) in a chlorinated solvent (CHCl3, and CH2Cl2 are popular choices; CCl4 is often cited in textbooks*) leads to the formation of products containing two bromine atoms.. Observation #1: Bromination Proceeds with anti stereochemistry. Possibly the most interesting feature of this reaction is that the products follow a very predictable stereochemical pattern. For instance, in the reaction of cyclohexene with Br2, the two bromine atoms add to opposite faces of the alkene (anti stereochemistry). No syn products are observed.. ...

Bromine - WikipediaBromine - Wikipedia
Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine and iodine. Bromine has the electron configuration [Ar]3d104s24p5, with the seven electrons in the fourth and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell.[16] Corresponding to periodic trends, it is intermediate in electronegativity between chlorine and iodine (F: 3.98, Cl: 3.16, Br: 2.96, I: 2.66), and is less reactive than chlorine and more reactive than iodine.

What is the best bromine chemistry for indoor pool - Swimming Pool HelpWhat is the best bromine chemistry for indoor pool - Swimming Pool Help
Thanks Chem Geek for your reply. I also asked this question in other forums and got different answers. Local pool supply shops suggested to not use a chlorine based shock because of the generation of unwanted chemistry in a bromine pool (dont remember now what that was supposed to be). In any case, I went with a non-chlorine shocker. I understand that with the DCDMH that shocking is not as necessary but I did use shocker with all the fresh water. In any case, the bromine testing seems to be good. The stabilizer, cyanuric acid, I understand to be required for chlorine in outside pools to protect from breakdown due to UV light. In any case, my understanding was that mono-chloroamine was the cause of chlorine smell. My pool is indoor and is directly attached to the basement floor in a walkout configuration. Still there was some cyanuric acid in the pool even though it should not be required. In any case, this configuration is very sensitive to the chemical smell. I have now moved on to a different ...

Bromine request from mwiemerBromine request from mwiemer
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 ...

Tire curing bladders are made from poly(isobutylene-co-4-bromomethylstyrene) with a benzylic bromine content of from 0.15 to 0.45 mole percent, vulcanized with a cure system of 1,6-hexamethylene-bis(sodium thiosulfate) and zinc oxide. The vulcanizate has low residual benzylic bromine content which leads to enhanced stability under severe duty applications, reduced hot tension set, and reduced adhesion or co-cure to halobutyl tire innerliners.

Bromine: Secret Toxin?. Reference: Endocrine Society, Oncology Letter,. Archives: www.newsinnutrition.com. What do you know about bromine? I bet not much. Its in the halide family, meaning the same family as chlorine and iodine and fluorine. Iodine is the biggest size of the lot, then smaller bromine, then chlorine and finally fluorine. They all share a negative one charge, so act the same chemically. They differ only in size and weight. Bromine is easily extracted from ocean salt brine pools, and is used industrially as a fire retardant. It used to be used as an insecticide in the form of methyl bromide, but that turned out to be a potent ozone depletor, so that got nixed. And once upon a time it was used as an anti-anxiety drug, and hence the term, Bromides for trite and trivial soothing answers.. The issue of bromine that I want to explore is that of its competition with iodine. We need iodine. Desparately. It is one of the elements that all of us are just barely getting enough of.

This brings up another point. With all the fluorine and chlorine we are exposed to from bathing, brushing our teeth, cooking with tap water, drinking tea, consuming chlorides such as sodium chloride (table salt), etc. why isnt every one breaking out in acne? After all fluorine and chlorine will both push bromine out of the system. On the other hand iodine is less reactive than bromine so the bromine if present will push the iodine out of the system. Yet they are claiming that the acne only occurs when they take the less reactive iodine that does not push bromine out of the body like fluorine and chlorine will ...

Photochemical Activation of Chlorine and Bromine from Iron-doped Saline Media - EPub BayreuthPhotochemical Activation of Chlorine and Bromine from Iron-doped Saline Media - EPub Bayreuth
The multifaceted role of halogen chemistry in the troposphere gained increasing attention in the last two decades. In particular, the interaction of Reactive Halogen Species (RHS) with ozone (O3) and nitrogen oxide (NOX) cycles (producing particulate matter and O3), as well as the consumption of methane (CH4) and volatile organic compounds by chlorine atoms (Cl) in competition with OH radicals, or the initiation of sudden O3 depletions by bromine (Br) atoms, are of major interest in atmospheric research. An important issue is the exploration and quantification of RHS sources and sinks, considering homogeneous and heterogeneous processes. The main focus of this work is the heterogeneous, photochemical formation of atomic Cl and Br in the presence of iron-doped saline media at various salt and gas-phase compositions. A Teflon smog chamber was employed to expose the samples to simulated sunlight under controlled conditions (air composition, temperature, relative humidity). The production of the ...

I dont think polarization is the issue. Adding $\ce{FeBr3}$ is just to reduce the $\ce{Br-Br}$ bond strength, speeding up the reaction (attack of the aromatic ring on the bromine is part of the rate determining step, which is slow in the bromination of benzene). It functions as a catalyst being recycled when the $\ce{Br-}$ grabs a $\ce{H+}$ to restore aromaticity in the ring. Im pretty sure - at least I see no reason to doubt - that the catalyst requirements for the bromination of anisole and the bromination of phenol do not differ much, if at all. That is, no catalyst is required for the bromination of anisole.. ...

Three new methods have been developed for the assay of cyproheptadine in bulk drug and in tablet formulation based on the bromination of cyproheptadine hydrochloride (CPH) by bromine generated in situ by the action of acid on bromate-bromide mixture. In titrimetry, the drug is treated with a known excess of bromate-bromide mixture in hydrochloric acid medium followed by the determination of unreacted bromine iodometrically. Spectrophotometry involves the addition of a measured excess of bromate-bromide reagent in acid medium to CPH, and after the reaction is ensured to be complete, the residual bromine is determined by reacting with a fixed amount of methyl orange, and measuring the absorbance at 520 nm. In kinetic method, a mixture containing CPH and methyl orange dye in 1 M sulphuric acid is mixed with bromate-bromide reagent at 4-5 C and time required for bleaching of methyl orange colour is measured. In titrimetry and spectrophotometry, the amount of bromine reacted corresponds to the amount ...

Poly maleic acid is prepared with maleic anhydride as reactant and peroxide of hydrogen as initiator in the solvent of water. The influences of the amount of catalyst and reaction temperature on its bromine value, viscosity, scale inhibition action are showed respectively by changing two reaction conditions including reaction temperature and the amount of catclyst. The effect of polymers bromine value and its viscosity on inhibiting scale is also investigated. The relationship between the scale inhibition action and amount of polymer added is also discussed. The experimental results state that the bromine value and viscosity and amount of polymer affect inhibiting scale, the best efficiency of sacle inhibition can be obtained by controlling polymers bromine value and viscosity according to reaction conditions. The efficiency of scale inhibition can not be enhanced when amount of polymer is added to certain degree.

Flame Retardant Chemical Found in US Soft Drinks - The Science Of EatingFlame Retardant Chemical Found in US Soft Drinks - The Science Of Eating
Both animal research and human studies of bromine have demonstrated its toxicity, finding links to lowered fertility, early puberty onset and impaired neurological development. Studies have also shown that bromine builds up in the heart, liver and fat tissue. The accumulation may also appear in breast milk. Because of this evidence, some health safety experts are concerned about bromines use even as a flame retardant which can be present in many household items.. Given the high levels of soda many people consume in the US, its presence in soft drinks is alarming. Health experts point in particular to the gamer culture where people may play video games for hours, drinking soft drinks throughout an extended session of gaming. Some soft drink companies, such as Mountain Dew, even offer game tie-ins, awarding players bonus points for drinking more of the soda.. ...

Taste-and-odour complaints are a leading cause of consumer dissatisfaction with drinking water. The aim of this study was to determine odour threshold concentration ranges and descriptors, using a Western Australian odour panel, for chlorine, bromine, chlorine added to bromide ions, the four major regulated trihalomethanes (THMs), and combined THMs. An odour panel was established and trained to determine odour threshold concentration ranges for odorous compounds typically found in drinking water at 25°C, using modified flavour profile analysis (FPA) techniques. Bromine and chlorine had the same odour threshold concentration ranges and were both described as having a chlorinous odour by a majority of panellists, but the odour threshold concentration range of bromine expressed in free chlorine equivalents was lower that that of chlorine. It is likely that the free chlorine equivalent residuals measured in many parts of distribution systems in Western Australia are comprised of some portion of ...

Retaining hexagonal lyotropic liquid crystal (LLC) structures in polymers after surfactant removal and drying is particularly challenging, as the surface tension existing during the drying processes tends to change the morphology. In this study, cross-linked poly(ethylene glycol) diacrylate (PEGDA) hydrogels were prepared in LLC hexagonal phases formed from a dodecyltrimethylammonium bromide (DTAB)/water system. The retention of the hexagonal LLC structures was examined by controlling the surface tension. Polarized light microscopy, X-ray diffraction and small angle X-ray scattering results indicate that the hexagonal LLC structure was successfully formed before polymerization and well retained after polymerization and after surfactant removal when the surface tension forces remained neutral. Controlling the surface tension during the drying process can retain the nanostructures templated from lyotropic liquid crystals which will result in the formation of materials with desired nanostructures ...

Halohydrin Formation - Alkene Reaction MechanismHalohydrin Formation - Alkene Reaction Mechanism
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. ...

July 2000. Background. Until 1999, DWI provided the support services for the voluntary approval system for chemicals used in swimming pool treatment. Following the decision to terminate the voluntary approval system, this study was commissioned in response to unresolved concerns about the conditions of approval for products based on the organobromine compound BCDMH.. Bromine-based disinfectants were introduced during the 1970s and early 1980s for use in recreational pools following the governments recommendation for the discontinuation of the use of chlorine gas. At the time, the perceived benefits of bromine were the improved bactericidal efficiency of bromination over chlorination (due to the greater biological activity of bromamines over chloramines, produced by the combination of the halogen with nitrogenous pollution - ie. urine), and the reduced scale of pH correction required, although it was recognized that elemental bromine is hazardous and capsulated dosing systems were recommended ...

BVO is patented by chemical companies as a flame retardant. It is also banned in over 100 countries, but it is still used in the U.S. Research shows that brominated flame retardants are building up in our bodies, and are linked to birth defects, growth problems, hearing loss, major organ system damage, early onset puberty and schizophrenia. Some individuals have reacted to drinking a beverage with BVO just once, while others dont show reactions unless they consume larger quantities. The reality is that Bromine is a fire retardant and considered an environmental toxin; it shouldnt be in any foods or drinks.. Many experts believe that the FDA standards for BVO based on data from 1977 are dated. Since laboratory testing technologies have advanced so rapidly, many feel that compounds such as bromine should be reexamined periodically, to verify that there arent any negative effects that may have been missed by prior inferior testing methods.

Alternatives to chlorine for your swimming poolAlternatives to chlorine for your swimming pool
Active oxygen (Aquablanc) is a sanitation system that uses Hydrogen Peroxide or Potassium Monopersulfate. It works in a very similar way to chlorine and bromine as it kills bacteria and breaks down contaminants in your water but unlike chlorine, it does not produce by-products which are often the cause for irritated skin, red eyes or that chlorine smell, it also dissipates quickly. Active oxygen is recommended for private domestic pools which are well maintained and looked after. It is not as strong as bromine or chlorine and therefore thorough regular maintenance is required to ensure your pool and hot tub remains in a good condition. However, it has become increasingly popular in recent years since it is odour free and offers a gentle alternative to those with sensitive skin. It is particularly recommended for those with children.. Pros: Gentle on skin, no odour, Aquablanc is an easy to use system, no more red-eye.. Cons: Not as strong, needs you to stay on top of cleaning and dosing. ...

Exposure to bromine gas inhalation during pregnancy causes preeclampsia-like symptoms, maternal death and severe fetal growth restriction. This project is supported by an NIH CounterACT U01 (Link to project in NIH Reporter). The CounterACT program supports basic and translational research aimed at the identification of better therapeutic medical countermeasures against chemical threat agents, and facilitates their movement through the drug development and regulatory processes in collaboration with other federal departments, agencies, and initiatives. (NIH CounterACT website). Briefly: The halogen bromine (Br2) is used as water disinfectant, for bleaching fibers, for manufacturing antiepileptic drugs, dyestuffs, flame-retardants, insecticides, drilling fluids, and gasoline additives. Exposure of pregnant mice at gestational day 15 (E15) to Br2 (600 ppm for 30 min.) results in 75% mortality over four days, in contrast to 25% mortality in males or non-pregnant females (p,0001).

In the 1960s, one slice of bread in the USA contained the full RDA of 0.15 mg iodine. The risk for breast cancer was then 1 in 20 (7). Over the last 2 decades, iodine was replaced by bromine in the bread making process. Bromine blocks thyroid function and may interfere with the anticancer effect of iodine on the breast. Now, the risk for breast cancer is 1 in 8 and increasing 1% per year (7 ...

You may have heard that photography is a snap. Thats because every picture begins with the snap of a shutter. When the shutter opens, light is captured and recorded on photographic film. It doesnt matter if the film youre shooting is black-and-white or color--the same chemical processes are at work. Black-and-white film is made by suspending billions of tiny silver halide crystals in gelatin and coating a clear sheet of plastic with the gelatin. Each tabular-shaped crystal contains silver and bromideions held together by strong electrostatic forces. Photons of light with the right amount of energy can change these crystals, producing silver ions, bromine atoms, and free electrons. An electron wanders through the crystal until it is captured by a silver ion. In the process, silver ions are changed into black metallic silver. The number of silver atoms formed depends on the amount of light each crystal receives. In an exposed crystal, as few as four silver atoms may form. These atoms usually ...

METHYLENE IODIDE (DIIODOMETHANE)METHYLENE IODIDE (DIIODOMETHANE)
Halogenoalkanes, also known as haloalkanes or alkyl halides, are organic compounds in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms, fluorine, chlorine, bromine or iodine. In carbon-halogen bond, halogens have significantly greater electronegativities than carbon except iodine. In result, this functional group is polarized so that the carbon is electrophilic and the halogen is nucleophilic. Halogenoalkanes are can be classified depending on the halogen atom position on the chain of carbon atoms. The carbon which is attached with the halogen atom is linked up with only one other alkyl group in primary halogenoalkanes, whereas directly linked up with two and three other alkyl groups in secondary halogenoalkanes and tertiary halogenoalkanes respectively. In some case, primary halogenoalkanes are counted even though there are no alkyl groups attached to the carbon with the halogen on it. Three characteristics provide important influences on the chemical behavior ...

Here, we investigate the strengths of R-X···π interactions, involving both chlorine and bromine, in model systems derived from protein-ligand complexes found in the PDB. We find that the strengths of these interactions can vary significantly, with binding energies ranging from −2.01 to −3.60 kcal/mol. Symmetry adapted perturbation theory (SAPT) analysis shows that, as would be expected, dispersion plays the largest role in stabilizing these R-X···π interactions, generally accounting for about 50% to 80% of attraction. R-Br···π interactions are, for the most part, found to be stronger than R-Cl···π interactions, although the relative geometries of the interacting pair and the halogens chemical environment can also have a strong impact. The two factors that have the strongest impact on the strength of these R-X···π interactions is the distance between the halogen and the phenyl plane as well as the size of the halogen σ-hole.

Chlorine Rash PreventionChlorine Rash Prevention
Even if you do decide to go for a swim in a chlorine-treated pool, make sure you take a shower before and right after the swim to prevent the rash from appearing!. Some health complications may accompany chlorine rash as a result of increased exposure. It can be a red rash on balls or just white spots on your testicles. A tightly fitting swim cap and pair of goggles prevents the chlorinated water from further reaching the hair and eye area. Skin Problems Caused by Swimming Pool Bromine - Swimming pool water needs disinfection and constant maintenance in order to keep it safe for swimmers. How can you prevent hot tub rash? If youre using a public hot tub or pool, the CDC recommends asking the person in charge if disinfectant (like chlorine) pH levels are checked at least twice a. Poison ivy, oak, and sumac are a great way to ruin a day in the outdoors. Chlorine helps eliminate harmful bacteria and other foreign agents that can build up in a body of water, especially when its exposed to a large ...

Tennessine - WikipediaTennessine - Wikipedia
The known isotopes of tennessine, 293Ts and 294Ts, are too short-lived to allow for chemical experimentation at present. Nevertheless, many chemical properties of tennessine have been calculated.[101] Unlike the previous group 17 elements, tennessine may not exhibit the chemical behavior common to the halogens.[10] For example, fluorine, chlorine, bromine, and iodine routinely accept an electron to achieve the more stable electronic configuration of a noble gas, obtaining eight electrons (octet) in their valence shells instead of seven.[102] This ability weakens as atomic weight increases going down the group; tennessine would be the least willing group 17 element to accept an electron. Of the oxidation states it is predicted to form, −1 is expected to be the least common.[5] The standard reduction potential of the Ts/Ts− couple is predicted to be −0.25 V; this value is negative, unlike for all the previous halogens.[2] There is another opportunity for tennessine to complete its octet-by ...

18251
  • Löwig isolated bromine from a mineral water spring from his hometown Bad Kreuznach in 1825. (wikipedia.org)
Periodic1
  • The atomic weight of an element such as bromine is located on the periodic table of eleme. (reference.com)
Irritation2
  • Breathing bromine gas could cause you to cough, have trouble breathing, get a headache, have irritation of your mucous membranes (inside your mouth, nose, etc.), be dizzy, or have watery eyes. (cdc.gov)
  • Symptoms of a bromine allergy may include difficulty breathing, coughing, lung sensitivity, headache, dizziness and possible skin irritation, such as a rash. (ehow.co.uk)
Symbol2
  • Bromine is a chemical element with the symbol Br and atomic number 35. (wikipedia.org)
  • The symbol for bromine is Br, and its atomic number is 35. (reference.com)
Ingredient1
  • Check for bromine as an ingredient on any fire-safe material. (ehow.co.uk)
Large quantities2
  • Bromine was not produced in large quantities until 1858, when the discovery of salt deposits in Stassfurt enabled its production as a by-product of potash. (wikipedia.org)
  • During the war, large quantities of bromine were used in asphyxiating and lachrymating gases. (dictionary.com)
Examples1
  • However, there are plenty of examples where Br or I make it into the final drug candidate or even marketed drug. (sciencemag.org)
Molecular2
  • What Is the Molecular Weight of Bromine? (reference.com)
  • The molecular weight of bromine is about 79.90 atomic mass units. (reference.com)
Symptoms5
  • Swallowing a large amount of bromine in a short period of time would be likely to cause symptoms such as nausea and vomiting (gastrointestinal symptoms). (cdc.gov)
  • Showing these signs and symptoms does not necessarily mean that a person has been exposed to bromine. (cdc.gov)
  • Occasionally, someone may have an allergy to bromine, which can cause serious symptoms. (ehow.co.uk)
  • Bromine allergy symptoms may be different depending on the severity of the allergy and the concentration of the bromine. (ehow.co.uk)
  • Bromine allergies have several different symptoms depending on how the chemical is encountered. (ehow.co.uk)
Exposure4
  • The seriousness of poisoning caused by bromine depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed. (cdc.gov)
  • Moving to an area with fresh air is a good way to reduce the possibility of negative health effects from exposure to bromine. (cdc.gov)
  • A clinically compatible case in which a high index of suspicion (credible threat or patient history regarding location and time) exists for bromine exposure, or an epidemiologic link exists between this case and a laboratory-confirmed case. (cdc.gov)
  • Morabia A, Selleger C, Landry JC, Conne P, Urban P, Fabre J. Accidental bromine exposure in an urban population: an acute epidemiological assessment. (cdc.gov)
Orbital1
Encounter2
  • The most common way to encounter bromine is to run across it in drinking water or in a swimming pool. (ehow.co.uk)
  • It involves attaching an atom of bromine to it, and pure bromine is not something that you want to encounter in a dark alley. (kqed.org)
Contaminated water1
  • Following the release of bromine into water, you could be exposed by drinking the contaminated water. (cdc.gov)
Chemical element1
  • A chemical element, like bromine, may have very little in common with a compound, say BVO, that contains the element. (kqed.org)
Rapidly2
  • If you think you may have been exposed to bromine, you should remove your clothing, rapidly wash your entire body with soap and water, and get medical care as quickly as possible. (cdc.gov)
  • Add a few drops of the bromine solution rapidly to each of the vials of toluene. (washington.edu)
