Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.

Antisense RNA strategies for metabolic engineering of Clostridium acetobutylicum. (1/704)

We examined the effectiveness of antisense RNA (as RNA) strategies for metabolic engineering of Clostridium acetobutylicum. Strain ATCC 824(pRD4) was developed to produce a 102-nucleotide asRNA with 87% complementarity to the butyrate kinase (BK) gene. Strain ATCC 824(pRD4) exhibited 85 to 90% lower BK and acetate kinase specific activities than the control strain. Strain ATCC 824(pRD4) also exhibited 45 to 50% lower phosphotransbutyrylase (PTB) and phosphotransacetylase specific activities than the control strain. This strain exhibited earlier induction of solventogenesis, which resulted in 50 and 35% higher final concentrations of acetone and butanol, respectively, than the concentrations in the control. Strain ATCC 824(pRD1) was developed to putatively produce a 698-nucleotide asRNA with 96% complementarity to the PTB gene. Strain ATCC 824(pRD1) exhibited 70 and 80% lower PTB and BK activities, respectively, than the control exhibited. It also exhibited 300% higher levels of a lactate dehydrogenase activity than the control exhibited. The growth yields of ATCC 824(pRD1) were 28% less than the growth yields of the control. While the levels of acids were not affected in ATCC 824(pRD1) fermentations, the acetone and butanol concentrations were 96 and 75% lower, respectively, than the concentrations in the control fermentations. The lower level of solvent production by ATCC 824(pRD1) was compensated for by approximately 100-fold higher levels of lactate production. The lack of any significant impact on butyrate formation fluxes by the lower PTB and BK levels suggests that butyrate formation fluxes are not controlled by the levels of the butyrate formation enzymes.  (+info)

Immunofluorescence detection of ezrin/radixin/moesin (ERM) proteins with their carboxyl-terminal threonine phosphorylated in cultured cells and tissues. (2/704)

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)

Dibromopropanone cross-linking of the phosphopantetheine and active-site cysteine thiols of the animal fatty acid synthase can occur both inter- and intrasubunit. Reevaluation of the side-by-side, antiparallel subunit model. (3/704)

The objective of this study was to test a new model for the homodimeric animal FAS which implies that the condensation reaction can be catalyzed by the amino-terminal beta-ketoacyl synthase domain in cooperation with the penultimate carboxyl-terminal acyl carrier protein domain of either subunit. Treatment of animal fatty acid synthase dimers with dibromopropanone generates three new molecular species with decreased electrophoretic mobilities; none of these species are formed by fatty acid synthase mutant dimers lacking either the active-site cysteine of the beta-ketoacyl synthase domain (C161A) or the phosphopantetheine thiol of the acyl carrier protein domain (S2151A). A double affinity-labeling strategy was used to isolate dimers that carried one or both mutations on one or both subunits; the heterodimers were treated with dibromopropanone and analyzed by a combination of sodium dodecyl sulfate/polyacrylamide gel electrophoresis, Western blotting, gel filtration, and matrix-assisted laser desorption mass spectrometry. Thus the two slowest moving of these species, which accounted for 45 and 15% of the total, were identified as doubly and singly cross-linked dimers, respectively, whereas the fastest moving species, which accounted for 35% of the total, was identified as originating from internally cross-linked subunits. These results show that the two polypeptides of the fatty acid synthase are oriented such that head-to-tail contacts are formed both between and within subunits, and provide the first structural evidence in support of the new model.  (+info)

Evidence for an inducible nucleotide-dependent acetone carboxylase in Rhodococcus rhodochrous B276. (4/704)

The metabolism of acetone was investigated in the actinomycete Rhodococcus rhodochrous (formerly Nocardia corallina) B276. Suspensions of acetone- and isopropanol-grown R. rhodochrous readily metabolized acetone. In contrast, R. rhodochrous cells cultured with glucose as the carbon source lacked the ability to metabolize acetone at the onset of the assay but gained the ability to do so in a time-dependent fashion. Chloramphenicol and rifampin prevented the time-dependent increase in this activity. Acetone metabolism by R. rhodochrous was CO2 dependent, and 14CO2 fixation occurred concomitant with this process. A nucleotide-dependent acetone carboxylase was partially purified from cell extracts of acetone-grown R. rhodochrous by DEAE-Sepharose chromatography. Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis suggested that the acetone carboxylase was composed of three subunits with apparent molecular masses of 85, 74, and 16 kDa. Acetone metabolism by the partially purified enzyme was dependent on the presence of a divalent metal and a nucleoside triphosphate. GTP and ITP supported the highest rates of acetone carboxylation, while CTP, UTP, and XTP supported carboxylation at 10 to 50% of these rates. ATP did not support acetone carboxylation. Acetoacetate was determined to be the stoichiometric product of acetone carboxylation. The longer-chain ketones butanone, 2-pentanone, 3-pentanone, and 2-hexanone were substrates. This work has identified an acetone carboxylase with a novel nucleotide usage and broader substrate specificity compared to other such enzymes studied to date. These results strengthen the proposal that carboxylation is a common strategy used for acetone catabolism in aerobic acetone-oxidizing bacteria.  (+info)

Urinary volatile constituents of the lion, Panthera leo. (5/704)

The volatile components of urine from lions were investigated using GC-MS headspace techniques. Fifty-five compounds were found in the urine samples. Seven potential species-identifying compounds were found. Male lion scent marks overlapped significantly more in compound composition with other males than they did with female marks. A similar relationship was not found for the females. Males had a significantly higher absolute content of 2-butanone in their urine than females, and females had a significantly higher relative content of acetone than males. Samples from 13/16 individual lions overlapped more within the individual than they did with samples from the other individuals, but only seven significantly so.  (+info)

Toxicokinetic interactions between orally ingested chlorzoxazone and inhaled acetone or toluene in male volunteers. (6/704)

The aim of this study was to examine if the drug chlorzoxazone has any influence on the toxicokinetics of acetone and toluene. Chlorzoxazone is mainly metabolized by the same enzyme (Cytochrome P450 2E1) as ethanol and many other organic solvents. Ten male volunteers were exposed to solvent vapor (2 h, 50 watt) in an exposure chamber. Each subject was exposed to acetone only (250 ppm), acetone + chlorzoxazone, toluene (50 ppm) only, toluene + chlorzoxazone, and chlorzoxazone only. Chlorzoxazone (500 mg) was taken as two tablets 1 h prior to solvent exposure. Samples of blood, urine and exhaled air were collected before, during and until 20 h post exposure. The samples were analyzed by head-space gas chromatography (acetone and toluene) and high-performance liquid chromatography (chlorzoxazone, 6-hydroxychlorzoxazone and hippuric acid). The time-concentration curves of acetone and toluene in blood were fitted to one- and four-compartment toxicokinetic models, respectively. Intake of chlorzoxazone was associated with slight but significant increases in the area under the blood concentration-time curve (AUC) and steady state concentration of acetone in blood, along with non significant tendencies to an increased half time in blood and an increased AUC in urine. Except for a delayed excretion of hippuric acid in urine, no effects on the toluene toxicokinetics were seen after chlorzoxazone treatment. Small increases in chlorzoxazone plasma levels were seen after exposure compared to chlorzoxazone alone. These interactions, although statistically significant, seem to be small compared to the interindividual variability on metabolism and toxicokinetics.  (+info)

Anti-tumor-promoting activity of a polyphenolic fraction isolated from grape seeds in the mouse skin two-stage initiation-promotion protocol and identification of procyanidin B5-3'-gallate as the most effective antioxidant constituent. (7/704)

Procyanidins present in grape seeds are known to exert anti-inflammatory, anti-arthritic and anti-allergic activities, prevent skin aging, scavenge oxygen free radicals and inhibit UV radiation-induced peroxidation activity. Since most of these events are associated with the tumor promotion stage of carcinogenesis, these studies suggest that grape seed polyphenols and the procyanidins present therein could be anticarcinogenic and/or anti-tumor-promoting agents. Therefore, we assessed the anti-tumor-promoting effect of a polyphenolic fraction isolated from grape seeds (GSP) employing the 7,12-dimethylbenz[a]anthracene (DMBA)-initiated and 12-O-tetradecanoylphorbol 13-acetate (TPA)-promoted SENCAR mouse skin two-stage carcinogenesis protocol as a model system. Following tumor initiation with DMBA, topical application of GSP at doses of 0.5 and 1.5 mg/mouse/application to the dorsal initiated mouse skin resulted in a highly significant inhibition of TPA tumor promotion. The observed anti-tumor-promoting effects of GSP were dose dependent and were evident in terms of a reduction in tumor incidence (35 and 60% inhibition), tumor multiplicity (61 and 83% inhibition) and tumor volume (67 and 87% inhibition) at both 0.5 and 1.5 mg GSP, respectively. Based on these results, we directed our efforts to separate and identify the individual polyphenols present in GSP and assess their antioxidant activity in terms of inhibition of epidermal lipid peroxidation. Employing HPLC followed by comparison with authentic standards for retention times in HPLC profiles, physiochemical properties and spectral analysis, nine individual polyphenols were identified as catechin, epicatechin, procyanidins B1-B5 and C1 and procyanidin B5-3'-gallate. Five of these individual polyphenols with evident structural differences, namely catechin, procyanidin B2, procyanidin B5, procyanidin C1 and procyanidin B5-3'-gallate, were assessed for antioxidant activity. All of them significantly inhibited epidermal lipid peroxidation, albeit to different levels. A structure-activity relationship study showed that with an increase in the degree of polymerization in polyphenol structure, the inhibitory potential towards lipid peroxidation increased. In addition, the position of linkage between inter-flavan units also influences lipid peroxidation activity; procyanidin isomers with a 4-6 linkage showed stronger inhibitory activity than isomers with a 4-8 linkage. A sharp increase in the inhibition of epidermal lipid peroxidation was also evident when a gallate group was linked at the 3'-hydroxy position of a procyanidin dimer. Procyanidin B5-3'-gallate showed the most potent antioxidant activity with an IC(50) of 20 microM in an epidermal lipid peroxidation assay. Taken together, for the first time these results show that grape seed polyphenols possess high anti-tumor-promoting activity due to the strong antioxidant effect of procyanidins present therein. In summary, grape seed polyphenols in general, and procyanidin B5-3'-gallate in particular, should be studied in more detail to be developed as cancer chemopreventive and/or anticarcinogenic agents.  (+info)

Thapsigargin has similar effect on p53 protein response to benzo[a]pyrene-DNA adducts as TPA in mouse skin. (8/704)

The level of p53 tumor suppressor protein increases in response to DNA damage caused by benzo[a]pyrene (B[a]P). The most used tumor promoter in the two step mouse skin carcinogenesis model, 12-O-tetradecanoylphorbol-13-acetate (TPA) decreases this response in mouse skin. In this study the effect of another promoter, thapsigargin was tested on B[a]P-induced p53 response using immunohistochemistry, western blotting and immunoelectron microscopy. We also studied the localization of p53 protein after treatments with BP and TPA or thapsigargin. Thapsigargin had a TPA-like effect on the acute induction of p53 protein related to benzo[a]pyrene-7, 8-diol-9,10-epoxide-DNA adducts in the skin of C57BL/6 mouse. After B[a]P treatment, there was slightly more putatively wild-type p53 protein in nuclei than in cytoplasm of the cells. Neither TPA nor thapsigargin affected the localization of p53 protein. Since both compounds increase the level of intracellular calcium, the inhibition of the p53 response may depend on the level of intracellular calcium. Inhibition of the putatively genome-protecting increase in p53 protein may be one of the critical effects of tumor promoters.  (+info)

Scientists at NDSU have developed a glucose monitor based on acetone in exhaled breath. The detection range encompasses normal through diabetic glucose levels, enabling versatility to monitor blood glucose in diabetic and pre-diabetic individuals, as well as tracking diet and athletic performance. Results are obtained in seconds, with the acetone concentration providing a direct indicator of blood glucose. The correlation between breath acetone and blood glucose is well known, but the ability to build this capability into a handheld device has been a hurdle. The NDSU sensor is very small, suitable for a handheld device, but with excellent accuracy and precision. Data may be compiled to provide a history (e.g. integration into a diabetes wellness app), while also providing immediately actionable information (e.g. blood sugar status). The acetone detector consists of semiconducting nanomaterial that includes tungsten oxide, a doping material, and oxygen, and requires no needles, patches, or other ...
The impact of including a more detailed VOC oxidation scheme (CRI v2-R5) with a multi-generational approach for simulating tropospheric acetone is investigated using a 3-D global model, STOCHEM-CRI. The CRI v2-R5 mechanism contains photochemical production of acetone from monoterpenes which account for 64% (46.8 Tg/yr) of the global acetone sources in STOCHEM-CRI. Both photolysis and oxidation by OH in the troposphere contributes equally (42%, each) and dry deposition contributes 16% of the atmospheric sinks of acetone. The tropospheric life-time and the global burden of acetone are found to be 18 days and 3.5 Tg, respectively, these values being close to those reported in the study of Jacob et al. (2002). A dataset of aircraft campaign measurements are used to evaluate the inclusion of acetone formation from monoterpenes in the CRI v2-R5 mechanism used in STOCHEM-CRI. The overall comparison between measurements and models show that the parameterised approach in STOCHEM-NAM (no acetone formation ...

PhD ceremony: Ms. H.M. Dudek, 12.45 uur, Academiegebouw, Broerstraat 5, Groningen. Dissertation: Redesign of Baeyer-Villiger monooxygenases for synthetic applications Promotor(s): prof. M.W. Fraaije. Faculty: Mathematics and Natural Sciences. Biocatalysis employs enzymes for performing chemical reactions which may lead to more efficient and environmentally friendly processes. Nowadays, it is possible to tailor properties of enzymes using protein engineering methods. The main goal of the research of Hanna Dudek was engineering phenylacetone monooxygenase (PAMO), a member of the Baeyer-Villiger family, into an efficient catalyst. First, she attempted changing coenzyme and substrate specificity of PAMO by site-specific mutagenesis. This resulted in moderate improvements of the enzyme properties, but nevertheless increased the knowledge on this class of enzymes. On the other hand, the limited success of the rational-engineering experiments underscored the need for alternative approaches. Therefore, ...
Various furans are considered as valuable platform chemicals as they can be derived from plant biomass. Yet, for their exploitation, follow-up chemistry is required. Here we demonstrate that Baeyer-Villiger monooxygenases (BVMOs) can be used as biocatalysts for the selective oxidation of several furans, including 5-(hydroxymethyl) furfural (HMF) and furfural. A total of 15 different BVMOs were tested for their activity on furfural, which revealed that most of the biocatalysts were active on this aromatic aldehyde. Phenylacetone monooxygenase (PAMO) and a mutant thereof (PAMOM446G) were selected for studying their biocatalytic potential in converting furfural and some other furans. While BVMOs are usually known to form an ester or lactone as a normal product by inserting an oxygen atom adjacent to the carbonyl carbon of the substrate, our results reveal that both biocatalysts produce furanoid acids as the main product from the corresponding aldehydes. Altogether, our study shows that BVMOs can be
This study combined photocatalytic technology with activated carbon cellulose-paper filter (ACCF) adsorption to decompose gaseous pollutants.

Skin contact with acetone is not recommended, as prolonged exposure can cause defatting of the skin. Acetones low boiling point of requires work in a ventilated area. While acetone is volatile and while its fumes are not particularly toxic, they can be irritating in large amounts. Acetone however is among the least toxic solvents, and as many studies have shown there are no long term risks in case of repeated exposure. The main danger of acetone comes from its flammability. Its vapors have a flash point much below room temperature, so air/acetone mixtures can explode or burst into flames easily, even from static shocks. At temperatures above 486 °C, acetone will self-ignite. ...

While the amount of acetone present in a patients breath is an accurate biomarker for blood glucose concentration, breathalyzer technology was previously not developed enough for clinical use. As a result, diabetics must use a fingerprick device multiple times per day to monitor blood glucose levels.. Now, researchers at Western New England University have developed a way of measuring breath acetone concentration using a cost-effective, portable medical device. In speaking with medGadget, Dr. Ronny Priefer of the universitys Department of Pharmaceutical and Administrative Sciences, and one of the scientists that developed the device, explained how the technology works.. According to Priefer, breath samples are composed primarily of water, with only a small fraction consisting of acetone. If acetone is only present in a few parts per billion, this presents a challenge in accurately quantifying the compound.. While most previous attempts at creating an acetone breathalyzer have applied a method ...

A new cytochrome P-450 isozyme (Mr = 52,000) was purified to apparent electrophoretic homogeneity from hepatic microsomes of mice treated with acetone and its biochemical, spectral, and immunological properties characterized. Several criteria indicated that the purified cytochrome was distinct from the known mouse P-450 isozymes. The absolute spectrum of its oxidized form indicated that it was in the high spin state. In a reconstituted system, it showed low catalytic activities towards 7-ethoxycoumarin, aminopyrine, and coumarin, whereas it catalyzed the oxidation of aniline, acetone, dimethylnitrosamine with high turnover number. The mouse enzyme was immunoreactive with polyclonal antibodies against rat P-450IIE1 and exhibited an NH2-terminal aminoacid sequence with a high homology to that of rat-P-450IIE1. Based upon the above catalytic, spectral, immunological and structural properties, the purified mouse P-450 appears to be the ortholog of previously described P-450IIE1(s) of other species ...

33 RECOVERY AND REUSE OF SPENT ACETONE VIA A MOBILE SOLVENT RECOVERY UNIT Mark W. Townsend, Senior Environmental Specialist Monsanto Company Addyston, Ohio 45001 BACKGROUND The Monsanto Chemical Company, an operating division of Monsanto Company, operates a plastics and resins plant located in Addyston, Ohio. One of the products manufactured at the Port Plastics facility is a styrene-maleic anhydride copolymer sold under the trade name Scripset®. The copolymer is produced by a polymerization process with the resulting solids ground into powder for sale to paper, adhesive, and photoplate manufacturers. The process equipment requires routine rinsing with technical grade acetone between batches. Due to the volumes of spent acetone generated and the associated RCRA hazardous waste regulations, the plant sought to recycle and reuse the acetone to reduce the purchase cost of virgin acetone and the cost of spent acetone disposal. One of the first options explored was package unit distillation units. ...
Two instances of finding abnormally high concentrations of acetone in urine (0.10 g/dL and 0.052 g/dL) without any measurable amounts of ethanol (, 0.005 g/dL) or isopropanol (, 0.005 g/dL) prompted a survey of the elimination kinetics of isopropanol and its metabolite acetone in humans. In a hospital patient who had ingested denatured alcohol, the elimination half- life (t( 1/2 )) of acetone during detoxification was 27 h and not 3-5 h as reported by other workers. Several other literature reports of individuals who had ingested isopropanol as well as controlled studies after administration of moderate amounts of acetone and/or isopropanol support the notion of a long elimination half-life of 17-27 h for acetone compared with a t( 1/2 ) of 1-3 h for isopropanol.. ...
This study was conducted to estimate the genetic parameters of β-hydroxybutyrate (BHBA) and acetone concentration in milk by Fourier transform infrared spectroscopy along with test-day milk production traits including fat %, protein % and milk yield based on monthly samples of milk obtained as part of a routine milk recording program in Korea. Additionally, the feasibility of using such data in the official dairy cattle breeding system for selection of cows with low susceptibility of ketosis was evaluated. A total of 57,190 monthly test-day records for parities 1, 2, and 3 of 7,895 cows with pedigree information were collected from April 2012 to August 2014 from herds enrolled in the Korea Animal Improvement Association. Multi-trait random regression models were separately applied to estimate genetic parameters of test-day records for each parity. The model included fixed herd test-day effects, calving age and season effects, and random regressions for additive genetic and permanent ...
Acetone definition, a colorless, volatile, water-soluble, flammable liquid, C 3 H 6 O, usually derived by oxidation of isopropyl alcohol or by bacterial fermentation of carbohydrates: used chiefly in paints and varnishes, as a general solvent, and in organic synthesis. See more.
Abstract: Photocatalysis of 2-propanol on A-TiO2(101) has been investigated using a temperature programed desorption method with 266 nm laser light. A clear mechanism is proposed for photodissociation of 2-propanol on A-TiO2(101). Acetone product on five coordinate Ti4+ sites is formed in a stepwise manner in which the O-H dissociation proceeds first and then followed by secondary C-H dissociation of 2-propanol while H atoms are transferred to the adjacent bridge bond oxygen (BBO) sites. Low temperature water is formed in a thermally driven process via H-atom on BBO in exchange with isopropyl groups of molecule 2-propanol, while isopropyl radical desorbs at high temperature during the TPD process. The observation demonstrates the prospect of TiO2 as a photocatalyst for degradation of organics.. ...

It doesnt matter if acetone is found in the childs urine or if it smells from the mouth - all this is called acetonemic syndrome. As a rule, the condition occurs in childhood. Usually people call it acetone in children, to simplify the concept. If the mother was told that the child in the urine had acetone or she felt a corresponding smell from her mouth, this does not mean that the child was poisoned or got to acetone. This experience is often the case with mothers of young children, because they are not always able to keep track of. In fact, the causes are in the internal processes of the body.. Acetonemic syndrome in children. This diagnosis means a list of symptoms that causes an increased concentration of ketone bodies in the blood. There are several theories why these bodies can increase in the blood: a drop in glucose or a violation of the regulation of glucose metabolism. But this does not mean that deterioration immediately sets in, it only occurs with provocative factors. ...
Acetone is a colourless, volatile, flammable liquid with a pungent sweetish odour. It is an inexpensive solvent that is useful for cleaning up liquid Polyester and Vinyl Ester Resins. It cannot dissolve them once they have cured. Acetone is not effective on Epoxy Resins. Acetone is useful for cleaning up waxes, adhesives, removing nail polish, cleaning up and removing some paints and lacquers. Prolonged or repeated exposure of Acetone to the skin removes natural oils, resulting in dryness or cracking. It must not be used to clean hands. Acetone readily forms a vapour at low temperatures and in small or poorly ventilated rooms this vapour can build up and can cause irritation to the eyes, nose and throat.. ...
TY - JOUR. T1 - Isotope effects in dipole-bound anions of acetone. AU - Hammer, Nathan I.. AU - Compton, Robert N.. AU - Adamowicz, Ludwik. AU - Stepanian, Stepan G.. PY - 2005/4/22. Y1 - 2005/4/22. N2 - Precision measurements using the Rydberg charge-exchange and electric field-detachment methods find that the dipole-bound electron affinity (EA) of acetone (C3H6O) is 55 ± 10 μeV greater than for deuterated acetone (C3D6O). The result agrees well with a theoretical prediction obtained with high-level electronic-structure and anharmonic vibrational calculations. The dipole moments calculated for the vibrationally averaged structures of C3H6O and C 3D6O show that the isotope effect (2% reduction) on the EA of acetone is mainly due to a slight reduction (0.5%) of the average dipole moment upon deuteration.. AB - Precision measurements using the Rydberg charge-exchange and electric field-detachment methods find that the dipole-bound electron affinity (EA) of acetone (C3H6O) is 55 ± 10 μeV ...
The results showed a definite decrease in the thickness after the treatment, though whether it was caused by the manicure or the removal process (the manicure must be soaked off in an acetone solution) remains unclear. Beauty editor Emma Hill is convinced that removing the varnish is the problem.. Acetone dries out your nails, she says.. My nails took four months to recover after I had two manicures back to back.. Samantha Sweet, a spokeswoman for Shellac, argues that if a trained technician applies and removes the nail polish, then this shouldnt be a problem.. Applying Shellac shouldnt damage the nail surface, she says.. The polish has a honeycomb construction, making it porous. The oils penetrate and nourish nails.. She also says proper removal means acetone soaked cotton wool is placed on the polish and left there just long enough to soften it.. You shouldnt be saturating the nail with acetone, and you certainly shouldnt soak the entire hand in a bowl of acetone, she ...

In your question, you didnt mention how low freezing temperature solvent system you are looking for instead of telling that the solvent has to remain liquid at the lowest possible temperature. And, Ivan Neretin mentioned that ethanol alone would get you about freezing temperature close enough to get you any ethanol+acetone solvent would get. For example, freezing point of ethanol is about $\pu{159 K}$, when compared to ~$\pu{155 K}$, the reported freezing point of ethanol:acetone (83:17) system (lowest of the system; see the chart given in your answer). Yet, freezing point of pure diethyl ether is $\pu{150.6 K}$, lower than the lowest achieved in acetone/ethanol system. Thus, I decided to list some low temperature systems for your convenience (Ref.1 & 2):. $$ \begin{array}{ccc}\hline \text{Solvent} &\text{Solute} & \text{Solvent mole fraction} & \text{Freezing point in}\; \pu{K} \\\hline \text{diethyl ether} & \text{none} & 1.0000 & 150.61 \\ \text{diethyl ether} & \text{acetone} & 0.9737 & ...

Acetone is a very volatile flammable liquid that is commonly used as a solvent. Nitrocellulose, parlon and red gum dissolve very well in acetone. The solution of nitrocellulose is called nitrocellulose lacquer. Working with acetone can be difficult as compositions dry out very quickly. The evaporation of the acetone also causes cooling of composition, sometimes even below 0° C. This can result in condensation of water.. ...

The reaction between the hydroperoxy radical, HO2, and acetone may play an important role in acetone removal and the budget of HOx radicals in the upper troposphere. We measured the equilibrium constants of this reaction over the temperature range of 215-272 K at an overall pressure of 100 Torr using a flow tube apparatus and laser flash photolysis to produce HO2. The HO2 concentration was monitored as a function of time by near-IR diode laser wavelength modulation spectroscopy. The resulting [HO2] decay curves in the presence of acetone are characterized by an immediate decrease in initial [HO2] followed by subsequent decay. These curves are interpreted as a rapid (,100 μs) equilibrium reaction between acetone and the HO2 radical that occurs on time scales faster than the time resolution of the apparatus, followed by subsequent reactions. This separation of time scales between the initial equilibrium and ensuing reactions enabled the determination of the equilibrium constant with values ...

so, why do i use pure acetone? the answer is super simple... i have no patience and pure acetone is the quickest way to remove any type of polish... INCLUDING GLITTER! i pour enough acetone into a bowl (i like to reuse the plastics tubs lunch meats come in) to cover all my nails on one hand, then put my nails in to soak. even glitter, which takes the longest to soak off, usually will easily rub off in under a minute! the issue with acetone, of course, is how harsh it is on your nails and skin. i counteract those effects by using Vaseline, cuticle creams and oils, and body lotion! making sure your skin and nails are moisturized are key parts towards insuring their health! dedication is also key... and i confess i sometimes slack pretty badly, and then my poor nails pay the price for my laziness ...
If youve never used one of these Acetone Antidotes, you are really missing out. Straight acetone is the best thing for removing nail polish, but it dries out your skin and leaves a horrible white caste across the skin. By mixing this vial into about 6oz of acetone you have a nourishing, moisturising, and fragrant polish remover without sacrificing any strength. I cannot live without these. I keep a mixed bottle (currently a Lord of Misrule blend), plus I add a drop of whatever new scent Im in the mood for to my clean-up dish. The best part is that once the acetone fully evaporates...your trash can will smell delightful. It is the little things in life, guys ...
1991-2001 draws rather sparingly from the Acetone official discography (four albums and three EPs), giving equal space to unreleased tracks and recently-unearthed home recordings. I recall that Acetone played rockers as well, maybe not always convincingly, yet youd never know it from this compilations focus on the bands dreamy style. The result is a narcotic listening experience that lets considerable air and light into an intimate sound. Intriguingly, 1991-2001 accompanies a new music biography, Hadley Lee Lightcap by Sam Sweet. The book traces Acetones rise from of the Cal Arts/Newport Beach nexus (the catalyzing of art-college music by suburban networks being a recurring theme in music history) to become the ur-band for todays buzzing Highland Park scene. The darkness lurking behind the music is made clear in the figure of Richie Lee, who committed suicide in 2001, but Hadley Lee Lightcap stresses the beauty in Acetone as a story and a sound specific to the arid concrete and scrub-brush ...

Cleanup The most common mistake is using too much glue. The next most common mistake is trying to remove glue from skin areas without acetone. The worst case is to glue your fingers together, and that is easily fixed by applying acetone to the glue. A tissue, a cotton ball or a cotton swab (Q-Tip) will soften the glue enough to pull the fingers apart gently. It will take a few minutes, but its worth the time to avoid tearing skin. A more common cleanup is getting glue off the cuticle, where the back of the nail meets the skin on the finger. This can be done any time, but is slightly easier within 10 minutes of getting the glue on there in the first place. A cotton swab with just one drop of acetone is enough, because the acetone will spread outward toward the end of the nail, where the insert is. We want to keep the acetone away from that area, especially as the glue is hardening. Just keep putting one drop of acetone at a time at the back of the cuticle, keeping it wet, and the glue will ...
