Properties of non-polymerizable tropomyosin obtained by carboxypeptidase A digestion. (1/1719)

Tropomyosin digested with carboxypeptidase A [EC] (CTM) shows a lower viscosity than the undigested protein in solution. From the relation between the viscosity decrease and the amount of amino acids liberated from the carboxyl terminus during this digestion, it is inferred that loss of the tri-peptide-Thr-Ser-Ile from the C-terminus is responsible for the decrease in viscosity. The secondary structure of -TM was not affected by the digestion according to circular dichroic measurements. The viscosity of CTM did not increase in methanol-water mixtures, whereas that of tropomyosin increased markedly. These results indicate that polymerizability was lost upon the removal of a small peptide from the C-terminus without change in the secondary structure. A decrease in the viscosity of tropomyosin solutions was observed on the addition of CTM, indicating that CTM interacts with intact tropomyosin. The dependence of the viscosity decrease on the amount of CTM showed that CTM binds tropomyosin in a one-to-one ratio as a result of end-to-end interaction. Since paracrystals having a 400 A repeated band structure could be grown in the presence of Mg ions at neutral pH, side-by-side interactions in CTM molecules remain intact, even though polymerizability is lost. The disc gel electrophoretic pattern showed that troponin could bind to CTM, but no increase in viscosity due to the complex was observed in solution. That is, the C-terminal part of tropomyosin is not required for the formation of the complex. The amount of CTM bound to F-actin was less than half of that bound to undigested tropomyosin, and could be reduced to one-tenth by a washing procedure. In the presence of troponin, however, the amount recovered to the level of tropomyosin normally bound to F-actin. Therefore, it is concluded that troponin is bound in the middle of the tropomyosin molecule and strengthens the binding of tropomyosin to F-actin.  (+info)

Immunofluorescence detection of ezrin/radixin/moesin (ERM) proteins with their carboxyl-terminal threonine phosphorylated in cultured cells and tissues. (2/1719)

Ezrin/radixin/moesin (ERM) proteins are thought to play an important role in organizing cortical actin-based cytoskeletons through cross-linkage of actin filaments with integral membrane proteins. Recent in vitro biochemical studies have revealed that ERM proteins phosphorylated on their COOH-terminal threonine residue (CPERMs) are active in their cross-linking activity, but this has not yet been evaluated in vivo. To immunofluorescently visualize CPERMs in cultured cells as well as tissues using a mAb specific for CPERMs, we developed a new fixation protocol using trichloroacetic acid (TCA) as a fixative. Immunoblotting analyses in combination with immunofluorescence microscopy showed that TCA effectively inactivated soluble phosphatases, which maintained the phosphorylation level of CPERMs during sample processing for immunofluorescence staining. Immunofluorescence microscopy with TCA-fixed samples revealed that CPERMs were exclusively associated with plasma membranes in a variety of cells and tissues, whereas total ERM proteins were distributed in both the cytoplasm and plasma membranes. Furthermore, the amounts of CPERMs were shown to be regulated in a cell and tissue type-dependent manner. These findings favored the notion that phosphorylation of the COOH-terminal threonine plays a key role in the regulation of the cross-linking activity of ERM proteins in vivo.  (+info)

Formate-induced inhibition of photoreceptor function in methanol intoxication. (3/1719)

Formic acid is the toxic metabolite responsible for the retinal and optic nerve toxicity produced in methanol intoxication. Previous studies in our laboratory have documented formate-induced retinal dysfunction and histopathology in a rodent model of methanol intoxication. The present studies define the time and concentration dependence of formate-induced retinal toxicity in methanol-intoxicated rats. Retinal function was assessed 24, 48, and 72 h after the initial dose of methanol by flicker electroretinographic measurements. Retinal histopathology was assessed at the same time intervals. Rod- and cone-mediated electroretinogram (ERG) responses were attenuated in a formate concentration- and time-dependent manner, and both retinal sensitivity and maximal responsiveness to light were diminished. Attenuation of UV-cone-mediated responses was temporally delayed in comparison to the functional deficits observed in the 15 Hz/510 nm responses, which have a rod-mediated component and occurred at significantly higher formate concentrations. Both 15 Hz/510 nm and UV-cone-mediated ERG responses were undetectable by 72 h; however, if light intensity was increased, a retinal ERG response could be recorded, indicating that photoreceptor function was profoundly attenuated, but not abolished, under these intoxication conditions. Functional changes preceded structural alterations. Histopathological changes were most pronounced in the outer retina with evidence of inner segment swelling, photoreceptor mitochondrial disruption, and the appearance of fragmented photoreceptor nuclei in the outer nuclear layer. The nature of both the functional and structural alterations observed are consistent with formate-induced inhibition of mitochondrial energy production, resulting in photoreceptor dysfunction and pathology.  (+info)

Positive selection of novel peroxisome biogenesis-defective mutants of the yeast Pichia pastoris. (4/1719)

We have developed two novel schemes for the direct selection of peroxisome-biogenesis-defective (pex) mutants of the methylotrophic yeast Pichia pastoris. Both schemes take advantage of our observation that methanol-induced pex mutants contain little or no alcohol oxidase (AOX) activity. AOX is a peroxisomal matrix enzyme that catalyzes the first step in the methanol-utilization pathway. One scheme utilizes allyl alcohol, a compound that is not toxic to cells but is oxidized by AOX to acrolein, a compound that is toxic. Exposure of mutagenized populations of AOX-induced cells to allyl alcohol selectively kills AOX-containing cells. However, pex mutants without AOX are able to grow. The second scheme utilizes a P. pastoris strain that is defective in formaldehyde dehydrogenase (FLD), a methanol pathway enzyme required to metabolize formaldehyde, the product of AOX. AOX-induced cells of fld1 strains are sensitive to methanol because of the accumulation of formaldehyde. However, fld1 pex mutants, with little active AOX, do not efficiently oxidize methanol to formaldehyde and therefore are not sensitive to methanol. Using these selections, new pex mutant alleles in previously identified PEX genes have been isolated along with mutants in three previously unidentified PEX groups.  (+info)

Distribution of gangliosides, GM1 and GM3, in the rat oviduct. (5/1719)

It is known that gangliosides, being ubiquitous membrane components, play important roles in cell-cell recognition, differentiation and transmembrane signalling. GM3, GM1 and GD1a were detected in the rat oviduct as major gangliosides by thin-layer chromatography (TLC) analysis. The total amounts of gangliosides from the oviducts at various times after hormone injection were not much changed. In order to identify their distribution and possible changes during ovulation, frozen sections of the rat oviducts were stained with specific monoclonal antibodies (MAbs) against the ganglio-series gangliosides. GM3 and GM1 were expressed in a different manner, but GD1a and other gangliosides were not immunohistochemically detected. In the ampullar region, GM3 was expressed in all the stroma and epithelial cells, but not GM1. GM1 was also not observed in epithelial cells. Staining by anti-GM1 monoclonal antibodies revealed long and minute thread-like structures in some of the stroma cells, whereas anti-GM3 monoclonal antibodies stained the entire cytoplasm, but not the nucleus, of all the stroma and epithelial cells. Other ganglio-series gangliosides, including GD1a, were not detected to some extent in the ampullar region by immunohistochemistry. Thus, these data suggest that GM3 and GM1 are oviduct-specific gangliosides.  (+info)

Effects of nickel and cobalt on kinetics of methanol conversion by methanogenic sludge as assessed by on-line CH4 monitoring. (6/1719)

When metals were added in a pulse mode to methylotrophic-methanogenic biomass, three methane production rate phases were recognized. Increased concentrations of Ni and Co accelerated the initial exponential and final arithmetic increases in the methane production rate and reduced the temporary decrease in the rate. When Ni and Co were added continuously, the temporary decrease phase was eliminated and the exponential production rate increased. We hypothesize that the temporary decrease in the methane production rate and the final arithmetic increase in the methane production rate were due to micronutrient limitations and that the precipitation-dissolution kinetics of metal sulfides may play a key role in the biovailability of these compounds.  (+info)

Antimalarial activities of various 4-pyridinemethanols with special attention to WR-172,435 and WR-180,409. (7/1719)

Pilot appraisals of the activities of 10 specially selected 2,6-substituted-4-pyridinemethanols against acute Plasmodium falciparum infections in owl monkeys identified three derivatives that were two to three times as active as chloroquine against infections with a 4-aminoquinoline-susceptible strain and, at the same doses, were equally effective against infections with a strain fully resistant to treatment with maximally tolerated doses of chloroquine, quinine, and pyrimethamine. Two of these derivatives, WR-172,435 and WR-180,409, deemed worthy of evaluation in human volunteers, were studied in greater depth in owl monkeys infected with either the multidrug-resistant Smith strain of P. falciparum or the pyrimethamine-resistant Palo Alto strain of P. vivax. These studies showed (i) that at the same total oral dose, 3-day and 7-day treatment schedules were equally effective and slightly superior to a single-dose schedule; (ii) that WR-172,435 was slightly more active than WR-180,409 in each treatment regimen; (iii) that intravenous delivery of WR-180,409 phosphate was feasible and effective; (iv) that both compounds effected control of parasitemia more rapidly than any standard or newly discovered antimalarial drug; and (v) that WR-172,435 and WR-180,409 had therapeutic indexes at least four to eight times those exhibited by chloroquine in infections with 4-aminoquinoline-susceptible strains, indexes retained by these pyridinemethanols against infections with various drug-resistant strains.  (+info)

Microbial oxidation of methane and methanol: isolation of methane-utilizing bacteria and characterization of a facultative methane-utilizing isolate. (8/1719)

A methane-utilizing organism capable of growth both on methane and on more complex organic substrates as a sole source of carbon and energy, has been isolated and studied in detail. Suspensions of methane-grown cells of this organism oxidized C-1 compounds (methane, methanol, formaldehyde, formate); hydrocarbons (ethane, propane); primary alcohols (ethanol, propanol); primary aldehydes (acetaldehyde, propionaldehyde); alkenes (ethylene, propylene); dimethylether; and organic acids (acetate, malate, succinate, isocitrate). Suspensions of methanol-or succinate-grown cells did not oxidize methane, ethane, propane, ethylene, propylene, or dimethylether, suggesting that the enzymatic systems required for oxidation of these substrates are induced only during growth on methane. Extracts of methane-grown cells contained a particulate reduced nicotinamide adenine dinucleotide-dependent methane monooxygenase activity. Oxidation of methanol, formaldehyde, and primary alcohols was catalyzed by a phenazine methosulfate-linked, ammonium ion-requiring methanol dehydrogenase. Oxidation of primary aldehydes was catalyzed by a phenazine methosulfate-linked, ammonium ion-independent aldehyde dehydrogenase. Formate was oxidized by a nicotinamide adenine dinucleotide-specific formate dehydrogenase. Extracts of methane-grown, but not succinate-grown, cells contained the key enzymes of the serine pathway, hydroxypyruvate reductase and malate lyase, indicating that the enzymes of C-1 assimilation are induced only during growth on C-1 compounds. Glucose-6-phosphate dehydrogenase was induced during growth on glucose. Extracts of methane-grown cells contained low levels of enzymes of the tricarboxylic acid cycle, including alpha-keto glutarate dehydrogenase, relative to the levels found during growth on succinate.  (+info)

The methylotrophic yeast Pichia pastoris can be used to express recombinant genes at high levels under the control of the methanol-inducible alcohol oxidase 1 (AOX1) promoter. Accurate regulation of the methanol concentration in P. pastoris cultures is necessary to maintain induction, while preventing accumulation of methanol to cytotoxic levels. We developed an inexpensive methanol sensor that uses a gas-permeable silicone rubber tube immersed in the culture medium and an organic solvent vapor detector. The sensor was used to monitor methanol concentration continuously throughout a fed-batch shake-flask culture of a P. pastoris clone producing the N-lobe of human transferrin. The sensor calibration was stable for the duration of the culture and the output signal accurately reflected the methanol concentration determined off-line by HPLC. A closed-loop control system utilizing this sensor was developed and used to maintain a 0.3% (v/v) methanol concentration in the culture. Use of this system ...
Methanol poisoning is a serious public health issue in developing countries, but few data are available in the literature on acute kidney injury (AKI) after methanol intoxication. This study examined the clinical features, spectrum and outcomes of AKI in patients with methanol intoxication and evaluated the predictors of mortality after methanol intoxication. A total of 50 patients with methanol intoxication were seen at Chang Gung Memorial Hospital between 2000 and 2013. Patients were grouped according to the status of renal damage as AKI (n = 33) or non-AKI (n = 19). Demographic, clinical, laboratory, and mortality data were obtained for analysis. Most patients were middle-aged (47.8 ± 14.9 years), predominantly male (74.0%), and habitual alcohol consumers (70.0%). Most incidents were oral exposures (96.0%) and unintentional (66.0%). Two (4.0%) patients attempted suicide by intravenous injection of methanol. Five (10.0%) patients suffered methanol intoxication after ingestion of methomyl pesticide
TY - JOUR. T1 - Real time measurements of methanol crossover in a DMFC. AU - Han, Jiahua. AU - Liu, Hongtan. PY - 2007/1/10. Y1 - 2007/1/10. N2 - Methanol crossover is a serious problem in a direct methanol fuel cell (DMFC), which causes significant voltage loss and waste of fuel. Due to methanol crossover, most DMFCs must operate on a fuel with a very low methanol concentration; yet very low methanol concentration also causes a poor cell performance. Thus, it is very important to find the optimal operating conditions of methanol concentration and other operating parameters. In this research, methanol crossover rate in a DMFC is determined by measuring the carbon dioxide concentration at the cathode exit in real time. By measuring methanol crossover and cell performances at different inlet methanol concentrations and various operating conditions three types of characteristics are identified in the relationships between methanol crossover and cell current density. Further analysis of these ...
In order to regulate methanol concentration, since the methanol crossover rate is roughly proportional to the methanol concentration at the anode, it is necessary to accurately sense the concentration of methanol in solution. Various types of sensors may be used to measure the concentration of methanol in an aqueous solution. Capacitance devices, which measure the change in the dielectric constant of the methanol solution, can be used as methanol sensors. However, the difference in dielectric constants for a methanol-water system is small leading to less accurate values. A sensing device, in wide range of methanol concentrations, up to about, 10 mol/L, would be very helpful for DMFC optimized operation. A passive mode design, of about 1/10th of a cm area, using a single parameter function, will be designed. The design and simulation would involve optimization of various parameters like the area of the working electrodes and counter electrodes, separation distance and overlap length between ...
In this work, methanol in crude glycerol solution was used to assist the lipid production with oleaginous yeast Trichosporon oleaginosus cultivated under non-sterilized conditions. The investigated methanol concentration was 0%, 1.4%, 2.2%, 3.3% and 4.4% (w/v). The results showed that methanol played a significant role in the non-sterilized fermentation for lipid production. The optimal methanol concentration was around 1.4% (w/v) in which the growth of T. oleaginosus was promoted and overcame that of the contaminants. The non-sterilized fed-batch fermentation with initial methanol concentration of 1.4% (w/v) was then performed and high biomass production (43.39 g/L) and lipid production (20.42 g/L) were achieved.. ...

Owing to the serious crossover of methanol from the anode to the cathode through the polymer electrolyte membrane, direct methanol fuel cells (DMFCs) usually use dilute methanol solutions as fuel. However, the use of high-concentration methanol is highly demanded to improve the energy density of a DMFC system. Instead of the conventional strategies (for example, improving the fuel-feed system, membrane development, modification of electrode, and water management), we demonstrate the use of selective electrocatalysts to run a DMFC at high concentrations of methanol. In particular, at an operating temperature of 80°C, the as-fabricated DMFC with core-shell-shell [email protected]@Pt nanocomposites at the anode and core-shell [email protected] nanoparticles at the cathode produces a maximum power density of 89.7 mW cm−2 at a methanol feed concentration of 10 M and maintains good performance at a methanol concentration of up to 15 M. The high selectivity of the electrocatalysts achieved through structural construction ...
Methanol oxidation catalysts comprising an outer Pt-shell with an inner Ni-core supported on carbon, (Pt-Ni/C), were prepared with either crystalline or amorphous Ni core structures. Structural comparisons of the two forms of catalyst were made using transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), and methanol oxidation activity compared using CV and chronoamperometry (CA). While both the amorphous Ni core and crystalline Ni core structures were covered by similar Pt shell thickness and structure, the Pt-Ni(amorphous)/C catalyst had higher methanol oxidation activity. The amorphous Ni core thus offers improved Pt usage efficiency in direct methanol fuel cells.
1. The effect of methanol on the β-galactosidase-catalysed hydrolysis of some nitrophenyl β-d-galactopyranosides has been studied under steady-state conditions. 2. The initial fractional rate of increase of kcat. as a function of methanol concentration with 2,4- and 3,5-dinitrophenyl β-d-galactopyranosides, but not with the other substrates studied, indicated that degalactosylation of the enzyme was rate-limiting. 3. The decrease in kcat. at high methanol concentrations for these substrates is considered to arise from causes other than galactosylation becoming rate-limiting. 4. Both galactosylation and degalactosylation of the enzyme require protonation of a group of pKa approx. 9.. ...
Abstract: A binary metallic catalyst (PtSn/C) and a ternary metallic catalyst (PtSnCo/C) with a metal mass fraction of 20% were prepared by borohydride reduction and subsequent hydrothermal treatment in a glycol liquid phase. The structure and composition of the as-prepared electrocatalysts were characterized by X-ray diffraction (XRD) and energy-dispersive spectrometry (EDS). Their activity and stability for the catalysis of methanol oxidation were evaluated by anodic linear sweep voltammetry (LSV), cyclic voltammetry (CV), and the anodic stripping of a pre-adsorbed CO monolayer. We found that the PtSnCo/C catalyst gave the best catalytic activity for the methanol oxidation of all the catalysts including the commercial JM-PtRu/C catalyst. After 100 cycles, the peak current of methanol oxidation for the PtSn/C catalyst rapidly decreased to 11% of its initial peak current but PtSnCo/C decreased to only 50%. This result suggests that the PtSnCo/C catalyst has better chemical stability for the ...
Methyl alcohol poisoning has been mainly reported in community. Two cases of methyl alcohol poisoning occurred in a small-sized subcontracted factory which manufactured smartphone parts in Korea. One young female patient presented with dyspnea and visual disturbance. Another young male patient presented with visual disturbance and myalgia. They treated with sodium bicarbonate infusion and hemodialysis for metabolic acidosis. In addition, he received ethyl alcohol per oral treatment. Her and his urinary methyl alcohol concentration was detected as 7.632 mg/L, 46.8 mg/L, respectively, although they were treated hemodialysis. Results of the working environment measurement showed that the concentration of methyl alcohol (1030.1-2220.5 ppm) in the air exceeded the time weighted average (200 ppm). They were diagnosed with optic neuropathy due to methyl alcohol poisoning and still have visual impairment. Workers who hired as dispatched employees in a small-sized subcontracted factory were exposed to high
A patient who is suspected to suffer from methanol toxicity should be brought to the hospital as soon as possible. Information such as the type of methanol the patient was exposed to, the amount and the time the exposure occurred will be helpful in the management of the toxicity [2].. Once the patient arrives at the hospital, the priority is to establish the airway and breathing. Intubation may be required if there is acute pulmonary distress or pulmonary edema. An intravenous access will also be established to administer fluid and medications. If the ingestion occurred less than 60 minutes prior, a tube may be inserted through the patients nose to remove any remaining poison in the stomach. Once the patient is stable, antidotes may be given to the patient.. The antidotes used for methanol toxicity are ethanol or fomepizole. These substances delay the metabolism of methanol until it is removed from the body either naturally or through the help of hemodialysis. Delayed metabolism of methanol ...
The electrochemical and in-situ surface-enhanced Raman spectroscopy (SERS) techniques were used to investigate the electrooxidation behavior of methanol in acidic, neutral and alkaline media at a Pt-Ru nanoparticle modified glassy carbon (Pt-Ru/GC) electrode. The results showed that methanol could be dissociated spontaneously at the Pt-Ru/GC electrode to produce a strongly adsorbed intermediate, CO. It was found that CO could be oxidized more easily in the alkaline medium than in the acidic and neutral media. The peak potential of methanol oxidation was shifted from 0.663 and 0.708 V in the acidic and neutral media to -0.030 V in the alkaline medium, which is due to that the adsorption strength of CO on the Pt surface in the alkaline medium is weaker than that in the acidic and neutral media. The final product of the methanol oxidation is C02. However, in the alkaline medium, CO2 proCO(2) duced would form CO32- and HCO3- resulting in the decrease in the alkaline concentration and then in the ...

Methanol crossover on the cathodes causes significant performance loss in direct methanol fuel cells, and the parasitic current induced by the electrochemical oxidation of methanol on the cathodes is believed to be the cause. Palladium cathodes are known to bear resistance to methanol but not platinum cathodes. By means of the density functional theory (DFT), the distorted molecular structure of the adsorbed methanol on platinum was revealed, and this distorted molecular structure indicates that platinum makes methanol has a tendency toward the elimination of the first hydrogen (involved in the first step of electrochemical oxidation of methanol) in electric neutrality, and loss of an electron can reinforce this tendency. However, palladium cannot distort the molecular structure of the adsorbed methanol, even in the loss of electron condition. The activation energies and the reaction energies calculated by means of DFT also show that after losing an electron, the elimination of the first ...

N2 - Direct methanol fuel cells are increasingly considered as an attractive power source for mobile applications because of the high energy density. The binary PtRu nanoparticle catalyst on carbon support is currently one of the most-studied electrocatalysts showing a bifunctional catalytic mechanism. A systematical electrochemical characterization of PtRu/Vulcan carbon catalysts (E-tek) for methanol oxidation under various conditions was carried out. The results revealed some initial insights into the experimental conditions for comparing the catalytic activities of different electrocatalysts. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA ...
The role of methanol produced in-situ in the liquid phase methanol synthesis process has been experimentally examined. The catalyst crystallite size is found to be more stable when the produced water and methanol are consistently removed from the catalyst active sites. The experimental evidence shows that in-situ produced water is not the only culprit for the catalyst crystallite size growth, rather, methanol is also responsible for contributing to crystallite growth and therefore catalyst deactivation. Hydrothermal leaching of the catalyst was also determined to be an active participant in catalyst deactivation. Two experimental designs were run to assess the influence of temperature, leaching solution concentration and pretreatment conditions on the extent of leaching of the methanol synthesis catalyst. Water and methanol were found to be active participants in the reduction of catalyst activity. Hence, the methanol/water solutions serve as potentially harmful agents in the leaching of aluminum and

The flowing electrolyte-direct methanol fuel cell (FE-DMFC) is a type of fuel cell in which a flowing liquid electrolyte is used, in addition to two solid membranes, to reduce methanol crossover. In this study, FE-DMFCs having new materials and design were manufactured and studied. In this design, the flow field plates were made of stainless steel 2205 and had a pin type flow structure. PTFE treated carbon felts were used as the backing layers as well as the flowing electrolyte channel. Nafion® 115 or Nafion® 212 was used as the membranes. The polarization curves and methanol crossover current densities under different methanol concentrations and flow rates of sulfuric acid were measured using fully automated DMFC test stations. The performances of the FE-DMFCs were compared with those of the DMFCs having a single or double membrane. This study is, to the authors knowledge, the first experimental study on measuring the methanol crossover in a FE-DMFC. The results of this study demonstrate that this
Theoretical calculations based on density functional theory have made significant contributions to our understanding of metal oxides, their surfaces, and the binding of molecules at these surfaces. In this paper we investigate the binding of methanol at the alpha-Al2O3(0001) surface using first-principles density functional theory. We calculate the molecular adsorption energy of methanol to be E^g_ads=1.03 eV/molecule. Taking the methanol-methanol interaction into account, we obtain the adsorption energy E_ads=1.01 eV/molecule. Our calculations indicate that methanol adsorbs chemically by donating electron charge from the methanol oxygen to the surface aluminum. We find that the surface atomic structure changes upon adsorption, most notably the spacing between the outermost Al and O layers changes from 0.11 Angstrom to 0.33 Angstrom.
The methanol-induced conformational transitions under acidic conditions for beta -lactoglobulin, cytochrome c, and ubiquitin, representing three different classes of proteins with beta -sheets, alpha -helices, and both alpha -helices and beta -sheets, respectively, are studied under equilibrium conditions by electrospray ionization mass spectrometry (ESI-MS). The folding states of proteins in solution are monitored by the charge state distributions that they produce during ESI and by hydrogen/deuterium (H/D) exchange followed by ESI-MS. The changes in charge state distributions are correlated with earlier studies by optical and other methods which have shown that, in methanol, these proteins form partially unfolded intermediates with induced ct-helix structure. Intermediate states formed at about 35% methanol concentration are found to give bimodal charge state distributions. The same rate of H/D exchange is shown by the two contributions to the bimodal distributions. This suggests the ...
The answer is Maybe 0.3% will probably be fine, but it depends on the cell line a lot. Note that if the drug is soluble in methanol, it will also be soluble in ethanol, which might be less toxic.. ...

Methanol toxicity is poisoning from methanol.[1] Symptoms may include a decreased level of consciousness, poor coordination, vomiting, abdominal pain, and a specific smell on the breath.[1][2] Decreased vision may start as early as twelve hours after exposure.[2] Long-term outcomes may include blindness and kidney failure.[1] Toxicity and death may occur even after drinking a small amount.[1] Methanol poisoning most commonly occurs following the drinking of windshield washer fluid.[2] This may be accidental or done purposefully in an attempt to die by suicide.[1] Toxicity may also rarely occur through extensive skin exposure or breathing in fumes.[1] When methanol is broken down by the body it results in formaldehyde, formic acid, and formate which cause much of the toxicity.[2] The diagnosis may be suspected when there is acidosis or an increased osmol gap and confirmed by directly measuring blood levels.[1][2] Other conditions that can produce similar symptoms include infections, exposure to ...

This PhD thesis deeply analyzes the mechanistic and kinetic behavior of methanol and dimethyl ether (DME) in the industrially relevant Methanol-To-Hydrocarbons (MTH) reaction, which employs zeolitic materials as catalysts. Industrial MTH processes use methanol, DME or combined methanol/DME feeds over zeolitic catalysts. Methanol and its dehydration product, DME, are conventionally attributed an analogous behavior in MTH; however, a thorough investigation on the theme was missing even though the MTH reaction has been studied for 40 years already. By means of mechanistic and kinetic studies, methanol has been found to negatively impact catalyst stability as compared to DME. This is rationalized based on the ability of methanol to form formaldehyde, a molecule that can act as coke promoter. Furthermore, the work presented in this PhD thesis suggest different strategies to reduce the impact of methanol on catalyst deactivation, thereby optimizing the lifetime of the catalyst during MTH operation ...
This study aims at investigating the emissions of cathode gas-phase polycyclic aromatic hydrocarbons (PAHs) from a single direct methanol fuel cell (DMFC) at different operating parameters (methanol concentration, methanol flowrate, oxygen flowrate, and cell temperature). At the standard test condition (run A1), the concentrations of stage 1 (S1) and S2 PAHs ranged from non-detect (ND) to 10.3 ± 2.54 (Nap) and ND to 0.148 ± 0.047 (IND) µg Nm-3, respectively; furthermore, the Total-PAHs and Total-BaPeq concentrations of S1 + S2 were 21.2 ± 4.48 µg Nm-3 and 409 ± 226 ng Nm-3, respectively. The operating parameters significantly influenced the patterns of PAH concentration profiles. Decreasing with increasing methanol flowrate and concentration or decreasing oxygen flowrate and cell temperature, the ranges of Total-PAHs and Total-BaPeq concentrations of S1 + S2 for different runs were (36.4 ± 10.9)‒(0.98 ± 0.21) µg Nm-3 and (409 ± 226)‒(98.7 ± 30.3) ng Nm-3, respectively, with corresponding
Background: Acute methanol poisoning is a fatal illness. Several Atypical presentations could make it difficult to suspect the diagnosis.. Case Report: A 50 years old male known chronic alcoholic presented to the emergency department with severe acute abdominal pain nausea and vomiting. He rapidly deteriorated within 2 hours to develop confusion and seizures, was found to have double gap severe metabolic acidosis and elevated serum methanol. The patient was managed with Continuous Renal Replacement Therapy (CRRT) and supportive measures. He gradually improved and was discharged with no neurological or visual complications.. Conclusion and Recommendations: Acute methanol toxicity should be expected if the alcoholic patient develops a rapid neurological deterioration and shows double anion gap acidosis.. Health authorities should provide the serum formic acid test for diagnosis and the fomepizole as a preferable antidote. Until then, supportive treatment, intravenous ethanol and CRRT should be ...

Objective: Methanol-induced optic neuropathy is a visual impairment that results from damage to the optic nerve fibers caused by methanol. It is frequently bilateral with permanent visual deterioration. According to the American Academy of Clinical Toxicology (AACT), methanol-poisoned patients who present with ocular manifestations should be treated with fomepizole, ethanol, or hemodialysis, which do not remove the metabolites from the optic nerve. High-dose intravenous steroid treatment has been proposed in several studies to salvage vision because of its anti-inflammatory effect. This article examines the existing literature on the efficacy of high-dose intravenous steroid treatment in patients with methanol-induced optic neuropathy. ...
One of the reasons why Methanol has the potential to be an enduring solution to human energy needs is because the beltched out C02 (greenhouse gas emission) both from using Methanol and while producing Methanol can be tapped back to produce Methanol. Thereby a seamless loop of CO2 sequestration cycle is created to perpetually burn fuels without polluting the environment at all. C02 from steel plants, Thermal Power plants, Cement Plants etc. can be tapped in large quantities to produce Methanol. The Technology has acquired commercial maturity and countries like Iceland are producing in meaningful quantities already.. NITI Aayog has drawn out a comprehensive plan to replace 20% of crude imports from Methanol alone. Adopting Methanol in this scale would bring down pollution in the country by more than 40% and not to forget the benefits from import substitution. Over a period of time of time diesel can completely be done away with. Indian Railways alone burns three billion litres of diesel every ...

Theres a useful general principle in chemistry where like dissolves like relative to polarity of solids and liquids. The light fraction of petroleum, literally it weighs less by volume, is hydrocarbons. Hydrocarbons are considered non-polar molecules. The petroleum distillates in petrol (gasoline) are also non-polar hydrocarbon molecules. Methanol alcohol is a hydroxide group bonded to a carbon atom with three hydrogen atoms also bonded to the carbon atom. A result is methanol is a polar molecule, it also participates in hydrogen bonding. Where like dissolves like, methanol is not like hydrocarbons relative to polarity. So methanol is not very miscible (soluble) in pure hydrocarbons. Pour lighter fluid into a jar with methanol and you will see, pure methanol doesnt dissovle much in lighter fluid. But methanol dissolves in biodiesel, and kerosene (hydrocarbon) is miscible (dissolves) to a degree in biodiesel ...
The discovery may also spur research leading to biofuel applications in the future. Methanol can be considered a baby sugar molecule and is rapidly consumed in the ocean by abundant bacteria - called methylotrophs - which specialize in this type of food, said Dr. Tracy Mincer, WHOI associate scientist and lead author of the paper.. However, up until now, the thought was that methanol in the ocean came from an overflow of terrestrial methanol in the atmosphere. So, this discovery reveals a huge source of methanol that has gone completely unaccounted for in global methanol estimates.. Mincer first became interested in the idea of biologically-produced methanol in the ocean through previous work where he found methanol-nibbling bacteria in a phytoplankton culture he was growing. Intrigued, he extracted the microbe s DNA and its barcodes matched up with a well-known methylotroph in the ocean. Once we were able to characterize this bacteria, I wanted to explore the idea of plankton-produced ...

TY - JOUR. T1 - Hydrogen bonding and dynamics of methanol by high-pressure diamond-anvil cell NMR. AU - Okuchi, Takuo. AU - Cody, George D.. AU - Mao, Ho Kwang. AU - Hemley, Russell J.. PY - 2005/8/1. Y1 - 2005/8/1. N2 - Liquid methanol at densities up to ρ ρ 0 =1.7 was studied by NMR in a specially designed diamond-anvil cell. Methyl and hydroxyl resonances have been separately observed at pressures to 43 kbars which exceeds equilibrium freezing pressure of methanol. The chemical shift difference between methyl and hydroxyl protons increases nonlinearly with increasing density, indicating a noticeable decrease in hydrogen bond length. The analyses of spin-lattice relaxation rates of both hydroxyl and methyl protons indicate that compression enhances intermolecular proton exchange and selectively reduces motion of the hydroxyl protons. Collectively these observations reveal that hydrogen bonding interaction in liquid methanol noticeably increases with compression, inhibiting the liquid-solid ...
Due to high potential of pollution risk of the untreated palm oil mill effluent (POME), it can be treated and converted into methane gas and with a further conversion that can produce into methanol. Previously, methanol is widely used in domestic and industrial applications as a solvent. It has a unique characteristic, which are colourless, flammable, volatile, odourless liquid that is readily miscible in water and has boiling point approximately 64.5˚C. Nowadays, the methanol has more been used in transportation and energy production. In future, it is predicted that the use of methanol in fuel applications will generate a huge demand. This study targets to design the process of transforming carbon dioxide, captured from the biogas through anaerobic digestion into synthesizing the methanol with the aim to produce 200 tonnes of methanol per year. This expectation is due to several advantages offered by the use of methanol, which less polluted to the environment, economically attractive, less ...

TY - GEN. T1 - Methanol adsorption and activation by zeolitic protons. AU - Blaszkowski, S.R.. AU - Santen, van, R.A.. PY - 1997. Y1 - 1997. N2 - Density functional theory is used to determine the modes of adsorption at low and high coverage of methanol as well as the intermediates involved in the Brønsted acid methanol dehydration to dimethyl ether. Two different reaction pathways were studied. In the first, methanol adsorption and surface methoxy species formation are the initial elementary steps for this reaction. Subsequent dimethyl ether formation by reaction of methanol with the surface methoxy species takes place. The second path involves the simultaneous adsorption and activation of two methanol molecules with formation of dimethyl ether and water in one step. The latter appears to be the preferred route. Additionally, carbon-carbon bond formation from the activation of methanol or dimethyl ether molecules by the surface methoxy groups was studied. The products are ethanol and ethyl ...
In 2011, North America imported more than three-quarters of its methanol from overseas. Methanol demand is projected to grow, as its applications continue to be used as green energy resources (methanol can be blended with other fuels to make a cleaner burning fuel; it is also used to make biodiesel). With increased demand, the price of methanol has continued to rise since 2009; additionally, in North America, the price of methanol includes the cost of shipping from another continent. Oberon provides a cost effective solution-it can produce methanol from an inexpensive domestic feedstock and locate production units near the end user, therefore reducing or eliminating shipping costs.. ...
The methanol to be produced is called green because the waste that is delivered is recycled in this process instead of burned. The waste - low-grade plastic and adhering green waste - is converted into syngas made of carbon (CO) and hydrogen (H2) and then into methanol. Normally methanol is made from natural gas and contributes to the emission of CO2. The total CO2 emissions are at least 65% lower than with fossil methanol. Air Liquide and Nouryon deliver the necessary raw materials, respectively oxygen and partly green hydrogen.. The planned factory converts 360,000 tons of waste - a waste stream of more than 700,000 households - into 220,000 tons of methanol every year. It is the first factory in Europe to produce chemicals and biofuels from non-recyclable waste. This is the first step towards a larger scale of methanol production, says Waas. Factories for fossil methanol are four to five times as large.. ...
Whod have thunk it - a chemistry conference full of space news. Its not that weird really, when you consider that the search for life = search for molecules.. Lars Kristensen from Leiden University in the Netherlands today showed us his maps of methanol in space. He is making these maps so he can see how methanol is distributed in the material that young stars are made from. Methanol is used as a tracer for early star formation and forms on the surface of interstellar ice-covered dust grains. Hell also soon be able to compare his methanol maps with results of water abundance from Herschel, which set off recently to check out the most distant objects in the universe.. Methanol forms as ice on dust grains. According to Kristensen, the major way that the methanol escapes from the surface of these grains is not by heating thermally, but by a non-thermal mechanism, be that activation by UV light, or other methods.. The abundance of methanol in the areas that Kristensen looked at, using the Harp B ...
