Pentachlorophenol (PCP), a xenobiocide used to preserve lumbers, is a major environmental pollutant in North America. In spite of an expected high resistance to biodegradation, a number of aquatic and soil bacteria can degrade PCP. In this study, we cloned, expressed and purified tetrachlorobenzoquinone reductase (PcpD), the second enzyme in the PCP biodegradation pathway in Sphingobium chlorophenolicum. PcpD, present mainly as a homo-trimer, exhibited low but statistically significant activity in the reduction of tetrachlorobenzoquinone to tetrachlorohydroquinone. The optimal pH for PcpD activity was 7.0. PcpD was stimulated by tetrachlorohydroquinone at low concentrations but inhibited at high concentrations. Because of the constitutive expression and relatively high catalytic efficiency of downstream enzyme tetrachlorohydroquinone reductive dehalogenase, tetrachlorohydroquinone was unlikely to accumulate in high concentrations, suggesting that PcpD would only be stimulated by tetrachlorohydroquinone

A sensor electrode to detect one or more components in a liquid mixture comprises an electrically conductive material having at least an an external surface, the combination of an enzyme catalytic for a reaction of the desired component, and a mediator compound which transfers electrons from the enzyme to the electrode when such catalytic activity takes place. It can be used as an in vivo glucose sensor either with a silver electrode coated with e.g. glucose oxidase and a polyviologen as the mediators, or with a particulate carbon electrode, glucose oxidase and chloranil or fluoranil as mediator. Another system is to use bacterial glucose dehydrogenase or glucose oxidase as the enzyme and/or ferrocene or a ferrocene derivative as the mediators compound to give electrodes with improved linearity, speed of response and insensitivity to oxygen.

The major glutathione S-transferase isoenzyme from bovine brain was isolated and purified approx. 500-fold. The enzyme has a pI of 7.39 +/- 0.02 and consists of two non-identical subunits having apparent Mr values of 22,000 and 24,000. The enzyme is uniformly distributed in brain, and kinetic data at pH 6.5 with 1-chloro-2,4-dinitrobenzene (CDNB) as substrate suggest a random rapid-equilibrium mechanism. The kinetics of inhibition by product, by GSH analogues and by NADH are consistent with the suggested mechanism and require inhibitor binding to several different enzyme forms. Long-chain fatty acids are excellent inhibitors of the enzyme, and values of 1nKi for hexanoic acid, octanoic acid, decanoic acid and lauric acid form a linear series when plotted as a function of alkyl chain length. A free-energy change of -1900 J/mol (-455 cal/mol) per CH2 unit is calculated for the contribution of hydrophobic binding energy to the inhibition constants. The turnover number of the purified enzyme dimer ...

Thousands of regions with higher than average mCG levels, which we term enriched residual methylation loci (ERML), were identified. We further show that persistence of mCG at a subset of these loci, including ERVs, germ-line genes, and a subgroup of imprinted DMRs, is dependent upon Setdb1. Finally, we provide evidence that Setdb1-mediated H3K9me3 promotes the stability of mCG at ERML at least in part by inhibiting Tet-dependent oxidation in these areas. Outcomes Characterization of Enriched Residual Methylation Loci in DKO mESCs. To comprehensively map the genomic areas that stay hypermethylated in the lack of the de novo Dnmts, we examined the genome-wide distribution of DNA methylation in past due passing DKO (passing 33) and WT (passing 39) parental mESCs by methylC-seq. In keeping with earlier studies, we discovered that apart from nearly ...

Vibrational spectra of CT complexes of acridine orange. Sagar Agravat, Vishal Jain & A T Oza*. Received 4 May 2007; revised 31 January 2008. Infrared spectra of acridine orange and its charge transfer complexes with acceptors such as chloranil, 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ), 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) and tetracyano-p-ethylene (TCNE) are reported here. Their photo conducting nature is explained with two absorption edges in infrared range associated with non-equivalent sites of chloride ion or formation of bonding, non-bonding and antibonding orbitals. The mid-IR transition is usually direct and the low-energy transition is indirect. Whether the transition is allowed or forbidden depends on average intermolecular distance. This differs from ordinary ternary complexes in which two acceptors give rise to two conduction bands. Also, there is absence of any screening found in two donor based ternary systems. There is some band tailing of phonon bands in absorption ...

Although previous studies have addressed the consequences of treating cells (5) or nucleosides (7) with TCBQ, the rates of physiologically relevant reactions between TCBQ and nucleophiles have not been examined. TCBQ reacts with thiols with rate constants ,1.4 × 106-1.3 × 107 M−1⋅s−1 at pH 7. The apparent decrease in reactivity going from cysteine to glutathione to β-ME correlates with their pKas (8.2, 9.2, and 9.6, respectively) (Fig. S1) and is consistent with the reactive moiety being the thiolate. Given these pKa values, 6%, 0.6%, and 0.3% of the thiols will be deprotonated at pH 7 for cysteine, glutathione, and β-ME, respectively. Thus, the rate constant for reaction between TCBQ and thiolates is ,108 M−1⋅s−1 , essentially the diffusion-controlled limit. It is important to note that each molecule of TCBQ can react with multiple thiols, leading to depletion of up to four molecules of glutathione per TCBQ (23). Further, reaction of TCBQ with multiple thiols can lead to ...

TY - JOUR. T1 - Poly-vinylidene-fluoride/p-benzoquinone gel polymer electrolyte with good performance by redox mediator effect for Li-Air battery. AU - Kim, Young Bok. AU - Kim, Il To. AU - Song, Myeong Jun. AU - Shin, Moo Whan. PY - 2016/8/20. Y1 - 2016/8/20. N2 - In this study, the poly-vinylidene fluoride (PVDF)/p-benzoquinone (pBQ) gel polymer electrolyte (GPE) is synthesized well with LiTFSI/TEGDME for Li-Air battery (LAB) applications. The PVDF/pBQ GPEs are characterized by electrochemical analysis and compared to the PVDF GPE. We confirm that pBQ molecule in PVDF GPE shows redox mediate behavior during charge-discharge process. Employing PVDF/pBQ GPE for LAB leads to an improved cycleability from 2 to over 30. In addition it results in a charge voltage decrease from around 4.2 V to around 3.3 V. The energy cycle efficiency (ECE) is improved about 15%. The pBQ accelerates to the formation of an amorphous phase on synthesized PVDF GPE matrix by acting inhibitor for polymerization. It leads ...

Free radical-triggered tissue damage is believed to play an essential role in a variety of human diseases. Pentachlorophenol (PCP) is applied as a pesticide worldwide in both industries and homes. It is used extensively as a biocide and wood preservative. Tetrachlorohydroquinone (TCHQ) was proved as a major toxic metabolite of PCP, contributing the release of free radicals during PCP metabolism. PCP has been proposed as a tumor promoter; however, only limited knowledge is available regarding the mechanisms of tumor promotion induced by PCP and its metabolite, TCHQ. A growing amount of literature suggests that a link between reactive oxygen species (ROS) and tumor promotion could exist. Herein, we summarize the findings regarding the ROS-triggered signaling pathways involved in the cytotoxicity and tumor promotion effects of PCP and TCHQ. Some of the notable findings demonstrated that TCHQ can induce DNA lesions and glutathione depletion in mammalian cells; meanwhile, oxidative stress and apoptosis

Gallic acid, also known as gallate or acid, gallic, belongs to the class of organic compounds known as gallic acids. These are organic compounds that contain a 3,4,5-trihydroxybenzoic acid moiety. Gallic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Gallic acid exists in all living species, ranging from bacteria to humans. Outside of the human body, Gallic acid is found, on average, in the highest concentration within a few different foods, such as mango, pomegranates, and cloves and in a lower concentration in red raspberries, cumins, and turnips. Gallic acid has also been detected, but not quantified in, several different foods, such as common walnuts, tarragons, gingers, fruit juices, and corns. This could make gallic acid a potential biomarker for the consumption of these foods. A trihydroxybenzoic acid in which the hydroxy groups are at positions 3, 4, and 5 ...

Machine fault prognosis techniques have been considered profoundly in the recent time due to their profit for reducing unexpected faults or unscheduled maintenance. With those techniques, the working conditions of components, the trending of fault propagation, and the time-to-failure are forecasted precisely before they reach the failure thresholds. In this work, we propose an approach of Least Square Regression Tree (LSRT), which is an extension of the Classification and Regression Tree (CART), in association with one-step-ahead prediction of time-series forecasting technique to predict the future conditions of machines. In this technique, the number of available observations is firstly determined by using Caos method and LSRT is employed as prognosis system in the next step. The proposed approach is evaluated by real data of low methane compressor. Furthermore, the comparison between the predicted results ...

Pentachlorophenol (PCP) is a widely used and highly toxic wood preservative. It was first introduced as a pesticide in 1936 (7) and is not known to be a natural product. Despite its recent introduction into the environment and its high toxicity, several strains of Sphingobium chlorophenolicum (previously Sphingomonas chlorophenolica) (24) that can mineralize PCP have been identified. The best studied of these are strains ATCC 39723 (19), RA-2 (23), and UG30 (6). It appears that S. chlorophenolicum has assembled a new metabolic pathway capable of converting this anthropogenic compound into a recognizable metabolite. Our previous studies suggest that this pathway has been assembled by patching together enzymes from at least two different metabolic pathways (8). PCP hydroxylase (PCP monooxygenase; EC 1.14.13.50) and 2,6-dichlorohydroquinone dioxygenase may have originated from enzymes that hydroxylated a naturally occurring chlorinated phenol and then cleaved the resulting hydroquinone. ...

Previously, Dembski had stated that neural nets were instances of evolutionary algorithms; in NFL, Dembski says that training neural nets by evolutionary computation are instances of evolutionary algorithms. The previous claim was simply false and the new claim is based upon the fact that some people do apply evolutionary computation to the problem of training neural nets. It reduces to the claim that instances of evolutionary computation are evolutionary computation; mentioning neural nets at all in that context seems unlikely to do anything but lead readers to the erroneous conclusion that the original claim has not been abandoned. Such basic errors as these reduce the credibility of his claims to achieve accurate representation ...

Using cyclic voltammetry, the electrochemistry of aqueous solutions of 4-methoxy-1,2-benzoquinone was investigated over the pH range 0-8. From the variation of half-wave potential with pH, it was inferred that the quinone was reduced to the hydroquinone; no acid-base reactions involving either the quinone or hydroquinone were observed. At low pH ( , 3), the cyclic voltammogram of the benzoquinone changed rapidly to a second pair of peaks at lower potentials. These were shown to be due to 2-hydroxy-1,4-benzoquinone, formed by hydrolysis of the original compound. The other hydrolysis product, methanol, was detected chromatographically. The hydrolysis reaction was shown to be first order both with respect to the 1,2-benzoquinone and protons. At pH 6 and above, 4-methoxy-1,2-benzoquinone showed a second type of decomposition whose rate was approximately first order in hydroxide ion. Using electrochemical and spectroscopic measurements, it was also demonstrated that 4-methoxy-1,2-benzoquinone was ...

I found nothing on any possible reaction between acetone and p-benzoquinone with SciFinder. If there would be a reaction under basic conditions, I would guess that 5-hydroxy-2-methylbenzofurane would be the expected product. I would guess the reason why this apparently does not happen is because benzoquinone is unlikely to be stable toward the strong bases required for the enolization of acetone (such as hydroxides which can react with quinones themselves ...

Living cells rely upon the detection of chemical alerts because of their existence. sound dominates both for low- and high-chemoattractant concentrations.

BackgroundThe objective of the present study was to test the ability of the partial least squares regression technique to impute genotypes from low density single nucleotide polymorphisms (SNP) panels i.e. 3K or 7K to a high density panel with 50K SNP. No pedigree information was used.MethodsData consisted of 2093 Holstein, 749 Brown Swiss and 479 Simmental bulls genotyped with the Illumina 50K Beadchip. First, a single-breed approach was applied by using only data from Holstein animals. Then, to enlarge the training population, data from the three breeds were combined and a multi-breed analysis was performed. Accuracies of genotypes imputed using the partial least squares regression method were compared with those obtained by using the Beagle software. The impact of genotype imputation on breeding value prediction was evaluated for milk yield, fat content and protein content.ResultsIn the single-breed approach, the accuracy of imputation using partial least squares regression was around 90 and 94% for

Pentachlorophenol (PCP) is present in most environmental compartments, including those which result in direct human exposure. This paper assesses the contribution made by different exposure routes and illustrates that the average non-occupationally exposed UK individual absorbs 0.05, 0.32 and 4.16 μg PCP per day from air inhalation, water and diet ingestion, giving a total absorption of 4.53 μg (total intake being 5.7 μg). Using data from other sources it appears that most human PCP body burdens are in the region of 550 μg. Using the body burden and calculated daily intakes it is concluded that either the half-life of PCP in the human body has been underestimated or that the UK body burden is below that found in other countries.. ...

It is usually more convenient to base programs for nonlinear regression on matrix algebra. This is the approach taken in higher level mathematical programming software such as that provided by Matlab and Mathcad (sources for the Matlab and Mathcad software are listed at the end of this chapter). The principles are exactly the same as in the algebraic approach discussed above, but matrix methods facilitate organization and manipulation of the data.. In matrix notation, the straight-line model can be expressed as [3, 5]. where Y is a vector containing the n values of y; (meas), X is an n X 2 sample matrix, e is a vector containing the observed residuals, and b is the vector containing values of the slope and intercept.

When I first tried this I bought a 30 % H2O2 under the name Baquacil and I tried the Erowid version of the synthesis and dripping the H2O2 with almost no fizzing in a two necked 500 ml rbf which only resulted in quinhydrone. Only until I boiled the reaction contents for a minute to a minute and a half while refluxing after I added the H2O2 wholesale did the hydroquinone go all the way to Benzoquinone after the boiling I would chill the rbf immediately in an icebath and then it would promptly go into the freezer for crystalization. Now I have returned to make more with the same gallon of H2O2 which I put in a refridgerator and I painted the walls when I added the H2O2 wholesale and tried to boil it the first time which prompted me to make a blast hood out of 2x4s and clear plastic. I took the Baquacil out of the fridge and let it sit for a day or two hoping the temp would raise and it would react like it did in the past and it seemed even more exothermic when I tried to add it wholesale somehow ...
