Reactivity of cyanate with valine-1 (alpha) of hemoglobin. A probe of conformational change and anion binding. (1/258)

The 3-fold increase in the carbamylation rate of Val-1 (alpha) of hemoglobin upon deoxygenation described earlier is now shown to be a sensitive probe of conformational change. Thus, whereas this residue in methemoglobin A is carbamylated at the same rate as in liganded hemoglobin, upon addition of inositol hexaphosphate its carbamylation rate is enhanced 30% as much as the total change in the rate between the CO and deoxy states. For CO-hemoglobin Kansas in the presence of the organic phosphate, the relative increase in the carbamylation rate of this residue is about 50%. These results indicate that methemoglobin A and hemoglobin Kansas in the presence of inositol hexaphosphate do not assume a conformation identical with deoxyhemoglobin but rather form either a mixture of R and T states or an intermediate conformation in the region around Val-1 (alpha). Studies on the mechanism for the rate enhancement in deoxyhemoglobin suggest that the cyanate anion binds to groups in the vicinity of Val-1 (alpha) prior to proton transfer and carbamylation of this NH2-terminal residue. Thus, specific removal with carboxypeptidase B of Arg-141 (alpha), which is close to Val-1 (alpha) in deoxyhemoglobin, abolishes the enhancement in carbamylation. Chloride, which has the same valency as cyanate, is a better competitive inhibitor of the carbamylation of deoxyhemoglobin (Ki = 50 mM) compared with liganded hemoglobin. Nitrate and iodide are also effective inhibitors of the carbamylation of Val-1 (alpha) of deoxyhemoglobin (Ki = 35 mM); inorganic phosphate, sulfate, and fluoride are poor competitive inhibitors. The change in pKa of Val-1 (alpha) upon deoxygenation may be due to its differential interaction with chloride.  (+info)

Effect of chronic sodium cyanate administration on O2 transport and uptake in hypoxic and normoxic exercise. (2/258)

Systemic O2 transport during maximal exercise at different inspired PO2 (PIO2) values was studied in sodium cyanate-treated (CY) and nontreated (NT) rats. CY rats exhibited increased O2 affinity of Hb (exercise O2 half-saturation pressure of Hb = 27.5 vs. 42.5 Torr), elevated blood Hb concentration, pulmonary hypertension, blunted hypoxic pulmonary vasoconstriction, and normal ventilatory response to exercise. Maximal rate of convective O2 transport was higher and tissue O2 extraction was lower in CY than in NT rats. The relative magnitude of these opposing changes, which determined the net effect of cyanate on maximal O2 uptake (VO2 max), varied at different PIO2: VO2 max (ml. min-1. kg-1) was lower in normoxia (72.8 +/- 1.9 vs. 81. 1 +/- 1.2), the same at 70 Torr PIO2 (55.4 +/- 1.4 vs. 54.1 +/- 1.4), and higher at 55 Torr PIO2 (48 +/- 0.7 vs. 40.4 +/- 1.9) in CY than in NT rats. The beneficial effect of cyanate on VO2 max at 55 Torr PIO2 disappeared when Hb concentration was lowered to normal. It is concluded that the effect of cyanate on VO2 max depends on the relative changes in blood O2 convection and tissue O2 extraction, which vary at different PIO2. Although uptake of O2 by the blood in the lungs is enhanced by cyanate, its release at the tissues is limited, probably because of a reduction in the capillary-to-tissue PO2 diffusion gradient secondary to the increased O2 affinity of Hb.  (+info)

Subchronic exposure to diisocyanates increases guinea pig tracheal smooth muscle responses to acetylcholine. (3/258)

OBJECTIVE: In order to study the threshold concentrations of isocyanates (IC) for induction of lung disorders, constrictive responses of tracheal smooth muscles to acetylcholine (ACH) in guinea pigs with and without diisocyanate [toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI) and diphenylmethane diisocyanate (MDI)] exposure were investigated. METHODS: An IC-induced increase in smooth muscle responsiveness was studied by measuring cumulative ACH dose responses (10(-10) to 10(-4) M ACH). Basal ACH dose-response curves, measured twice in intervals of 1 h using tracheal preparations of 11 guinea pigs previously not exposed to IC, were reproducible. RESULTS: Subchronic in vivo exposures to TDI, HDI, and MDI atmospheres of 10 and 20 parts per billion (ppb) on 5 consecutive days led to significantly (p < 0.05) increased ACH responsiveness of tracheal smooth muscle, whereas concentrations of 2.5 and 5 ppb were not effective. Exposure to HDI atmospheres of 10 ppb for 1, 2, 4, or 8 weeks resulted in a time-dependent increase in ACH responses (p < 0.05) of guinea pig tracheal smooth muscle. Increased tracheal muscle responses to ACH were transient since tracheal preparations from animals exposed to 10 and 20 ppb MDI for 4 weeks and with an exposure-free interval of 8 weeks before preparation did not show enlarged ACH responses, which were present in preparations at the end of the exposure period (p < 0.05). Exposure to low IC concentrations as present in workplaces cause increased ACH responsiveness of guinea pig tracheal smooth muscle. The increased responsiveness of the airways seems to be largely reversible, since normal responses were found after 8 weeks of IC avoidance. CONCLUSION: Reversibility of IC-induced airway hyperresponsiveness is of great occupational and preventive medical importance. Workers with acquired airway hyperresponsiveness might escape lung damage if the changes are detected in an early stage before alterations in lung function are in a chronic stage.  (+info)

Bioactivation of cyanide to cyanate in sulfur amino acid deficiency: relevance to neurological disease in humans subsisting on cassava. (4/258)

Neurological disorders have been reported from parts of Africa with protein-deficient populations and attributed to cyanide (CN-) exposure from prolonged dietary use of cassava, a cyanophoric plant. Cyanide is normally metabolized to thiocyanate (SCN-) by the sulfur-dependent enzyme rhodanese. However, in protein-deficient subjects where sulfur amino acids (SAA) are low, CN may conceivably be converted to cyanate (OCN-), which is known to cause neurodegenerative disease in humans and animals. This study investigates the fate of potassium cyanide administered orally to rats maintained for up to 4 weeks on either a balanced diet (BD) or a diet lacking the SAAs, L-cystine and L-methionine. In both groups, there was a time-dependent increase in plasma cyanate, with exponential OCN- increases in SAA-deficient rats. A strongly positive linear relationship between blood CN- and plasma OCN- concentrations was observed in these animals. These data are consistent with the hypothesis that cyanate is an important mediator of chronic cyanide neurotoxicity during protein-calorie deficiency. The potential role of thiocyanate in cassava-associated konzo is discussed in relationship to the etiology of the comparable pattern of motor-system disease (spastic paraparesis) seen in lathyrism.  (+info)

Treatment of intradural paraclinoidal aneurysms. (5/258)

Intradural paraclinoidal aneurysm still presents conceptual confusion and technical surgical problems. The clinical features of 68 consecutive patients with paraclinoidal aneurysms were analyzed. The pterional approach was used in all patients. Subarachnoid hemorrhage (SAH) occurred in 37 patients from the paraclinoidal aneurysm and in 10 patients from another associated aneurysm. Thirty-four of the 37 ruptured paraclinoidal aneurysms were clipped, two blister-like aneurysms required trapping, and one blister-like aneurysm was coated. Thirteen of the 31 unruptured paraclinoidal aneurysms, consisting of 10 with ruptured associated aneurysm, four symptomatic, and 17 incidental, were clipped and 18 were coated. Favorable outcomes were obtained in 38 of 47 patients with SAH and 17 of 21 patients without SAH. Nine unfavorable outcomes in SAH patients were caused by primary brain damage (5), vasospasm (2), cerebral infarction after trapping (1), and pneumonia (1). All four unfavorable outcomes in non-SAH patients were due to surgical procedures for giant aneurysms or associated basilar artery aneurysm. Removal of the anterior clinoid process was performed to secure the proximal neck in 15 patients with large or giant aneurysms. Multiple clips with or without fenestrated clips were required in all giant aneurysms, and exposure of the cervical internal carotid artery (ICA) in 17 giant or large aneurysms. Fenestrated clips were also useful for one small aneurysm projecting posteriorly. A favorable outcome was achieved in 17 of 19 patients undergoing coating. Coating without clipping might be better for some blister-like ICA aneurysms, even if ruptured. Paraclinoidal aneurysms can be clipped with favorable results using these techniques except for giant aneurysms and associated basilar artery aneurysm.  (+info)

Biological monitoring to assess exposure from use of isocyanates in motor vehicle repair. (6/258)

OBJECTIVES: To develop a method for the measurement of a metabolite of hexamethylene diisocyanate (HDI), an isocyanate, and use it to assess the exposure of sprayers employed in motor vehicle repair shops. METHODS: Urine samples were taken from sprayers wearing personal protective equipment and spraying in booths or with local exhaust ventilation, from bystanders, and from unexposed subjects. Samples were analyzed for a metabolite of HDI, hexamethylene diamine (HDA), by gas chromatography-mass spectrometry (GC-MS). RESULTS: HDA was detected in four sprayers and one bystander out of 22 workers. No HDA was detected in the urine of unexposed subjects. CONCLUSIONS: Exposure to isocyanates still occurs despite the use of personal protective equipment and the use of a booth or extracted space. Health surveillance is likely to be required to provide feedback on the adequacy of controls even if such precautions are used and to identify cases of early asthma. Biological monitoring can provide a useful additional tool to assess exposure and the adequacy of controls in this group of exposed workers.  (+info)

Histological changes in the rat common carotid artery following simultaneous topical application of cotton sheet and cyanoacrylate glue. (7/258)

Histological changes in and around the arterial walls of rats were investigated following simultaneous topical application of cotton sheet and cyanoacrylate glue. The bilateral common carotid arteries were exposed using sterile techniques, and the test materials were applied to the right artery. The left artery served as a control. Changes in arterial histology were evaluated at 2 weeks, 1 month, 2 months, and 3 months after surgery. Extensive inflammation consisting primarily of histiocytes and multinuclear giant cells was observed around the materials, but tended to decrease by 3 months. Necrosis in the media and fibrosis in the adventitia initially appeared around 2 weeks, and became advanced by 2-3 months. At 2-3 months, disruption of elastic fibers and marked fibrosis in the media were seen, and endothelial proliferation in the intima appeared. Intimal proliferation was observed at both the experimental and other sites of the vessels. The present results suggest that simultaneous use of the test materials can cause the arterial occlusive lesions observed following aneurysmal surgery.  (+info)

Exposure biomarkers and risk from gluing and heating of polyurethane: a cross sectional study of respiratory symptoms. (8/258)

OBJECTIVES: To define the relation between exposure to polyurethane (PUR) glue, biomarkers of exposure and effect, and work related symptoms that occur at least once a week. METHODS: In a cross sectional study, 152 workers and 14 clerks in a factory with exposure to sprayed and heated PUR glue containing 4, 4'-diphenylmethane (MDI) or 1,6-hexamethylene (HDI) di-isocyanate were examined with gas chromatography-mass spectrometry (GC-MS) for metabolites of MDI in plasma (P-MDX) and urine (U-MDX), 2,4- and 2, 6-toluene di-isocyanate (TDI; P-TDX, U-TDX) and HDI in plasma and urine, specific serum IgG (S-IgG-MDI, S-IgG-HDI, and S-IgG-TDI, respectively) and IgE (S-IgE-MDI). Work related symptoms of the eyes and airways (nose or lower airways, or both), and lung function were also evaluated. RESULTS: P-MDX was detected in 65% of the workers, U-TDX in 47%, HDX in none. Three per cent were positive for S-IgE-MDI, 33% for S-IgG-MDI, 32% for S-IgG-TDI, and 12% for S-IgG-HDI. A few clerks had metabolites, and some had antibodies. Most metabolites and immunoglobulins were slightly correlated-for example, P-MDX v S-IgG-MDI: r(s)=0.21. Workers who heated glue had increased P-MDX (odds ratio (OR)=12 for a value above the median) and S-IgG-MDI (OR=3.7), sprayers P-2,4-TDX (OR=6.2) and P-2,6-TDX (OR=16). Twenty six per cent of the workers had work related symptoms of the airways, 21% from the nose, 11% from the lower airways. Spraying of glue increased the risk of work related symptoms and slightly decreased lung function. U-MDX was associated with work related symptoms from the airways (OR=3.7) and P-2,6-TDX with work related symptoms from the lower airways (OR=6.6). S-IgG-MDI was related to work related symptoms from the airways (OR=2.6). CONCLUSIONS: There were relations between exposures to sprayed and heated PUR glue based on MDI and HDI, concentrations of metabolites of MDI and TDI in plasma and urine, specific IgG serum antibodies against MDI, TDI, and HDI, and work related symptoms.  (+info)

Diffusion phenomena during cyanate resin cure<...
TY - JOUR. T1 - Diffusion phenomena during cyanate resin cure. AU - Deng, Yong. AU - Martin, George C.. PY - 1996/8. Y1 - 1996/8. N2 - The diffusion phenomena, including the molecular diffusion processes and the effect of diffusion on the cure kinetics and molecular size distribution, during the curing of a zinc-catalysed cyanate ester resin have been studied. The average diffusivity, which was estimated using the dielectric analysis-based approach, decreased by several orders of magnitude during the curing process. The molecular size distribution measured with size exclusion chromatography was found to deviate from the mean-field prediction at relatively high conversions. By using the Rabinowitch model, a diffusion-controlled kinetic model was formulated, which adequately predicted the experimental cyanate conversion profiles over the entire range of cure..

Escherichia coli can overcome the toxicity of environmental cyanate by hydrolysisof cyanate to ammonia and bicarbonate. This reaction is catalyzed by the enzymecyanase, encoded by the cynS gene. The nucleotide sequence of cynS has beenreported (Sung, Y.-c., Anderson, P. M., and Fuchs, J. A. (1987) J. Bacteriol.169, 5224-5230). The nucleotide sequence of the complete cyn operon has now been determined. The cyn operon is approximately 2600 base pairs and includes cynT,cynS, and cynX, which encode cyanate permease, cyanase, and a protein of unknown function, respectively. Two cyanate-inducible transcripts of 1500 and 2500nucleotides, respectively, were detected by Northern blot analysis. S1 nucleasemapping experiments indicated that two different cyn mRNAs have a common 5-endand two different 3-ends. One 3-end was located within the coding region ofcynX, whereas the other 3-end includes the entire DNA sequence of cynX. Thelonger transcript contained 98 nucleotides complementary to lac mRNA ...

Cyanate therapy of sickle-cell disease is currently under investigation. Since cyanate-treated erythrocytes have increased oxygen affinity, we studied the effect of chronic cyanate administration on tissue oxygen delivery in rats. Sodium cyanate (CNO) was administered for 8 weeks to two groups of rats. Thirty received 625 mg/kg body weight-week orally, and 30 received 250 mg/kg body weight-week intraperitoneally. Control animals received equivalent amounts of NaCl. Animals were killed at 2, 4, and 8 weeks, and blood oxygen affinity (P50), erythrocyte 2, 3-diphosphoglycerate (DPG), hematocrit, and erythrocyte mass were measured. Tissue oxygen delivery was assessed by skin bubble oxygen tension (SBpO2). ...

after he obtained his doctorate in Medicine, Surgery, and Midwifery he was encouraged by the chemist Leopold Gmelin to continue his chemical investigations. At Gmelins suggestion Woehler sought a position in the laboratory of the Swedish chemist Berzelius. In the Swedish lab he pursued studies on his recently synthesized cyanic acid. This led to the preparation of silver cyanate which, in turn, would lead to a collaboration with Justus von Liebig and the discovery of the property of isomerism. Woehler continued his chemical studies and in 1828 reported the finding that the combination of potassium cyanate with ammonium sulfate led to the production of a compound that was identical in composition to that of the naturally occurring compound urea. In 1836 Woehler accepted a position at Goettingen where he proceeded to develop one of the great teaching laboratories of the world. Although he seemed destined to be a major force in the development of Organic Chemistry Woehler returned to his roots in ...

Synthesis and characterization of heterocyclic polymers :polybenzoxazoles and cyanate ester networksSynthesis and characterization of heterocyclic polymers :polybenzoxazoles and cyanate ester networks
High molecular weight soluble aromatic polybenzoxazoles (PBO) were synthesized from various bis( ortho amino phenols) and aromatic diacid chlorides via solution step polymerization in Nmethyl- 2-pyrrolidone (NMP). It was demonstrated that reaction temperatures of about 0 Cor lower were highly desired in order to obtain high molecular weight polyhydroxy amides. It was postulated that this lower temperature prevented pyridine catalyzed side reactions with the phenol group, which would otherwise either limit molecular weight or produce branched or gelled structures. The polyhydroxy amides were successfully solution cyclized at elevated temperatures (170 C) and complete cyclization was demonstrated with reactions times of 6 hours or less. The reSUlting fluorinated PBO materials were soluble in amide solvents at concentrations of at least 150/0 at 25 C.

Methyl Isocyanate - Hazards | Technology Trends
Hazards. Methyl isocyanate (MIC) is extremely toxic. The threshold limit value set by the American Conference on Government Industrial Hygienists is 0.02 ppm. MIC is toxic by inhalation, ingestion and contact in quantities as low as 0.4 ppm. Exposure symptoms includes coughing, chest pain, dyspnea, asthma, irritation of the eyes, nose and throat, as well as skin damage. Higher levels of exposure, over 21 ppm, can result in pulmonary or lung edema, emphysema and hemorrhages, bronchial pneumonia and death. Although the odor of methyl isocyanate cannot be detected at 5 ppm by most people, its potent lachrymal properties provide an excellent warning of its presence (at a concentration of 2-4 parts per million (ppm) subjects eyes are irritated, while at 21 ppm, subjects could not tolerate the presence of methyl isocyanate in air).. Proper care must be taken to store methyl isocyanate because of its ease of exothermically polymerizing (see Reactions) and its similar sensitivity to water. Only ...

TY - JOUR. T1 - Autoradiographic analyses of Guinea pig airway tissues following inhalation exposure to C-labeled methyl isocyanate. AU - Kennedy, Amy L.. AU - Singh, Gurmukh. AU - Alarie, Yves. AU - Brown, William E.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Through the use of radioactively labeled methyl isocyanate (MIC), the deposition, penetration, and clearance of this highly reactive compound in the airway at the tissue and cellular levels have been directly examined. Guinea pigs were exposed to 14C-MIC vapors at concentrations ranging from 0.38 to 15.2 ppm for periods of 1-6 hr. Solubilization of tissues from these animals showed the airway tissues to have the highest level of radioactivity. In the nasal region, 14C deposition, as monitored by histoautoradiography, was limited to the epithelial layer, was related to dose, and was dependent on the specific epithelial cell type. The squamous epithelium was minimally labeled on the surface and the label did not penetrate the cell layer. However, ...

OBJECTIVES: The pathogenic basis of respiratory disorders associated with isocyanates are still obscure. One reason for this is the lack of good estimates of human exposure. In this study exposure was estimated by measurement of isocyanate metabolites in biological samples. METHODS: In a factory using isocyanate based polyurethane (PUR) glue, isocyanate concentrations in air were measured by liquid chromatography. Samples from 174 employees were analysed for metabolites of 4,4-methylene diphenyl diisocyanate (MDI) in plasma (P-MDX) and urine (U-MDX). After hydrolysis, 4,4-methylenedianiline was measured by gas chromatography-mass spectrometry (GC-MS). The employees were screened for work related respiratory symptoms and tested for specific immunoglobulin E (IgE) and IgG antibodies directed against isocyanate conjugated to human serum albumin. RESULTS: The time weighted isocyanate concentrations in air were low (MDI , 0.2-7; hexamethylene diisocyanate (HDI) , 0.1-0.7; 2,6-toluene diisocyanate ...

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was blended with poly(lactic acid) (PLA) with various reactive processing agents to decrease its brittleness and enhance its processability. Three diisocyanates, namely, hexamethylene diisocyanate, poly(hexamethylene diisocyanate), and 1,4-phenylene diisocyanate, were used as compatibilizing agents. The morphology, thermomechanical properties, and rheological behavior were investigated with scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry, tensile testing, dynamomechanical thermal analysis in torsion mode (dynamic mechanical analysis), and oscillatory rheometry with a parallel-plate setup. The presence of the diisocyanates resulted in an enhanced polymer blend compatibility; this led to an improvement in the overall mechanical performance but did not affect the thermal stability of the system. A slight reduction in the PHBV crystallinity was observed with the incorporation of the diisocyanates. The ...

By Kavita Krishnan. July 2010 -- Liberation -- More than 25 years after the infamous Bhopal gas disaster, the verdict of a trial court in Bhopal is nothing but a cruel mockery of justice. With charges already diluted by the Supreme Court of India, the June 7 trial court verdict could only be a formal burial of justice. Not only does the verdict insult the victims of one of the worlds worst industrial disasters by letting off, either scot-free or with a ridiculously light sentence, the mighty CEOs who were the chief perpetrators, it amounts to an assurance to multinational corporations that they will enjoy total impunity in India even when their negligence and violations of regulations leads to the loss of thousands of Indian lives and injury to several thousand more. On December 2-3, 1984, 40 tonnes of methyl isocyanate (MIC) leaked out of the Union Carbide Corporations pesticide plant in Bhopal, exposing more that 5,000,000 people to the toxic fumes. As many as 25,000 people have died as a ...

Leicester Research Archive: Some aspects of the chemistry of chlorosulphonyl isocyanate.
The reactions of chlorosulphonyl isocyanate with cyclic 1, 3-dienes gave thermally unstable N-chlorosulphonyl B-lactams which were intercepted by reduction to the corresponding stable NH-B-lactams. The exclusively Markovnikov orientation of the addition suggests a considerable degree of dipolar character in the transition state. Stepwise rearrangement of the initial 1, 2-addition products to thermodynamically more stable 1, 4-addition or substitution products was observed and the assignment of these products is discussed. The invertomer ratios and activation energies for inversion at nitrogen in several 2-chloro-2-zabicyclo [2, 2, 17] and [2, 2, 2] systems, derived from rearrangement products obtained in the reactions of chlorosulphonyl isocyanate with 1, 3-cyclopentadiene and 1, 3-cyclohexadiene, were determined using variable temperature n.m.r. spectroscopy. The assignment of the invertomers, and factors influencing the invertomer ratio and activation energy for inversion at nitrogen in ...

We investigated whether late asthmatic reactions and the associated increase in airway responsiveness induced by toluene diisocyanate (TDI) in sensitized subjects are inhibited by indomethacin and/or prednisone. Four sets of experiments were conducted in five subjects sensitized to TDI. To assess late asthmatic reactions to TDI, FEV1 was measured immediately before and after exposure to TDI and then hourly for 8 h. To assess change in airway responsiveness, the provocative dose (mg) of methacholine that caused a decrease in FEV1 of 20% (PD20FEV1) before treatment, and then before and after exposure to TDI was measured. In the first set of experiments, each subject was given no treatment and was studied before and 8 h after exposure to TDI; in the other two sets, each subject was studied before treatment, then during treatment with indomethacin (50 mg q.i.d. for 3 days, orally) or prednisone (50 mg once a day, for 3 days, orally), both before and 8 h after TDI exposure.

What Community is this book trying describe? It is certainly not Bhopal, in India, where in 1984 a release of methyl isocyanate from a chemical plant operated by an affiliate of Union Carbide Corporation killed at least 4,000 people and (according to the Indian government) left some 50,000 people permanently injured and unable to work. It is certainly not Butte, Montana, where much of the old mining community is now a Superfund site that dramatically exemplifies the problem of acid mine drainage, a problem that is common in much of the American West. Within a short walk from the center of Butte, residents and visitors can gaze on the Berkeley Pit -- an open pit, about a mile in diameter, that now is flooded with some 30 billion gallons of mine-drainage water. This water, which stands 700 feet deep above 200 feet of sediment, is very acidic and has 107 ppm of aluminum, 150 ppm of iron, 159 ppm of zinc, 49 ppm of copper and 1 ppm of cadmium, among other things.

Food (cassava) linamarin is metabolized into neurotoxicants cyanide and cyanate, metabolites of which we sought to elucidate the differential toxicity effects on memory. Young 6-8 weeks old male rats were treated intraperitoneally with either 2.5 mg/kg body weight (bw) cyanide (NaCN), or 50 mg/kg bw cyanate (NaOCN), or 1 μl/g bw saline, daily for 6 weeks. Short-term and long-term memories were assessed using a radial arm maze (RAM) testing paradigm. Toxic exposures had an influence on short-term working memory with fewer correct arm entries (F 2, 19 = 4.57 p , 0.05), higher working memory errors (WME) (F 2, 19 = 5.09, p , 0.05) and longer RAM navigation time (F 2, 19 = 3.91, p , 0.05) for NaOCN relative to NaCN and saline treatments. The long-term working memory was significantly impaired by cyanide with fewer correct arm entries (F 2, 19 = 7.45, p , 0.01) and increased working memory errors (F 2, 19 = 9.35 p , 0.05) in NaCN relative to NaOCN or vehicle treated animals.

Beckmann rearrangement - WikipediaBeckmann rearrangement - Wikipedia
Presumably after the phenyl group migrates and expels the cyanate, it then attacks the nitrillium ion formed. In carbon tetrachloride the isocyanate can be isolated, whereas in ethanol the urethane is formed after solvolysis of the isocyanate. One computational study has established the mechanism accounting for solvent molecules and substituents.[6] The rearrangement of acetone oxime in the Beckmann solution involved three acetic acid molecules and one proton (present as an oxonium ion). In the transition state leading to the iminium ion (σ-complex), the methyl group migrates to the nitrogen atom in a concerted reaction as the hydroxyl group is expelled. The oxygen atom in the hydroxyl group is stabilized by three acetic acid molecules. In the next step the electrophilic carbon atom in the nitrilium ion is attacked by water and a proton is donated back to acetic acid. In the transition state leading to the imidate, the water oxygen atom is coordinated to 4 other atoms. In the third step, an ...

Two-component adhesive
The present invention relates to two-component adhesive for bonding wood materials.. Previously polyurethane adhesives used for bonding wood materials, including, in particular, bearing glued wooden structures (wooden building structures), such as, for example, structural elements (laminated wooden beams, wall elements and so on). In such applications are used as two-component and one-component curing in a moist environment, adhesives. In the case of the latter system after application of the adhesive passes the initial reaction between isocyanates and moisture from the ambient air or substrate: part used isocyanate with the release of carbon dioxide is formed corresponding amine and then it reacts with the isocyanate with the formation of urea due to release of CO2.. The reaction of aromatic isocyanates with hydroxyl groups (water or alcohols) by several orders of magnitude faster than the corresponding aliphatic isocyanates. However, the aromatic system makes aromatic isocyanates are sensitive ...

Coherence and anticoherence resonance in high-concentration erbium-doped fiber laserCoherence and anticoherence resonance in high-concentration erbium-doped fiber laser
We report an experimental study of low-frequency (similar to 10 kHz) self-pulsing of the output intensity in a high-concentration erbium-doped fiber laser. We suggest that the fast intensity fluctuations caused by multimode and polarization instabilities play the role of an external noise source, leading to low-frequency auto-oscillations through a coherence resonance scenario.. ...

The test substance is covered by the category approach of methylenediphenyl diisocyanates (MDI). Hence, data of the category substances can be used to cover this endpoint. Yakabe et al (1994) found that for loadings of 400 - 10,000 mg/L, and under heterogeneous conditions, oligomeric MDI had a half-life of ca. 20h at 25°C when the disappearance rate was fitted to a zero-order kinetic model. However the rate constant increased approximately linearly with the nominal concentration of oligomeric MDI for all constituents. For the two-ring constituents the rate constant was found to be 0.5h-1 (i.e. half-life = 1.4 hour) for a loading of 1000 mg/L oligomeric MDI. The findings in the Yakabe et al (1994) study concur with the generally accepted chemistry of hydrolysis of an isocyanate whereby the initially produced carbamate decarboxylates to amine which then reacts very readily with more isocyanate to produce a urea. For a diisocyanate of low solubility such as MDI, the reaction system is usually ...
