Replication of mycoplasmavirus MVL51. IV. inhibition of viral synthesis by rifampin - Publications of the IAS Fellows
The effect of rifampin on the replication of MVL51, a bullet-shaped mycoplasmavirus with single-stranded circular DNA of molecular weight 2 X 10(6), has been examined in a rifampin-resistant host cell. Rifampin does not block the early steps in MVL51 infection but does decrease the total amount of parental viral DNA taken up. The single-stranded parental viral DNA that enters the cell is found in membrane-associated, double-stranded DNA replicative forms I and II. Rifampin had no significant effect on the synthesis of progeny viral DNA RFI and RFII early in infection and SSI (single-stranded progeny viral chromosomes) later in infection. The rifampin block in virus synthesis was found to be in the step converting SSI into assembled virions. Rifampin was shown to affect the synthesis of virus-specific RNA, Which suggests that viral transcription is necessary for virion assembly. ...
Phase equilibria of aqueous solutions of formaldehyde and methanol: Improved approach using UNIQUAC coupled to chemical...
The study of the phase equilibria involving formaldehyde is still relevant because of its presence in new processes where biomass is the raw material. The coupling between physical phase equilibria and chemical reactions makes its thermodynamic description a challenging task. In this work, an improved approach using UNIQUAC coupled to chemical equilibria was developed and compared with experimental data from the literature. The first application was done for the phase equilibria of the formaldehyde-water system and distribution of oligomers in the liquid phase was computed. The second and the third applications respectively considered the phase equilibria of the formaldehyde-methanol system and the formaldehyde-water-methanol system. ...
Exploring the Interplay of Lipids and Membrane Proteins
The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models.. A monotopic membrane protein, monoglucosyldiacylglyecerol synthase (MGS) from Acholeplasma laidlawii is known to induce intracellular vesicles when expressed in Escherichia coli. The mechanism leading to this unusual phenomenon was investigated by various biochemical and biophysical techniques. The results indicated a doubling of lipid synthesis in the cell, which was triggered by the selective binding of MGS to anionic lipids. Multivariate data analysis revealed a good correlation with MGS production. Furthermore, preferential anionic lipid sequestering by MGS was shown to induce a different fatty acid modeling of E. coli membranes. The roles of specific lipid binding and the probable mechanism leading ...

Adsorption of mycoplasma virus P1 to host cells
The adsorption of mycoplasma virus P1, a virus which infects some strains of Mycoplasma pulmonis, to host cells was examined. Mutants of M. pulmonis to which P1 virus did not adsorb were isolated. Proteins from the mutants and from wild-type cells were compared by two-dimensional polyacrylamide gel electrophoresis, and the only observed difference was in the surface antigen V-1. The electrophoretic properties of V-1 also correlated with the host range of the virus. These data strongly suggest that the V-1 antigen affects adsorption of P1 virus to host cells ...

Molecular simulation and modeling of the phase equilibria of polar compounds.
The initial phase of the project involved an investigation into the modeling of binary carboxylic acid vapour-liquid equilibrium (VLE) data. This stemmed from the Masters research that led into the current study, in which the conventional gamma-phi formulation of VLE was found to inadequately describe the complicated acid chemistry. In an effort to correctly describe the dimerization occurring in both the liquid and vapour phases, the chemical theory of vapour-phase imperfections was applied. The chemical theory technique allowed the experimental liquid-phase activity coefficients to be accurately calculated by taking the vapour phase dimerization into account. Once these activity coefficients had been determined, standard Gibbs excess energy models were fitted to permit analysis of the VLE datas thermodynamic consistency. In addition, the typical bubble-point iteration scheme used for VLE data regression was adapted to include the chemical theory expressions necessary for satisfactory modeling ...
Measurement and correlation of phase equilibria for poly(ethylene glycol) methacrylate + alcohol systems at 298.15 K
The activities of methanol, ethanol, 2-propanol, and 1-butanol in poly(ethylene glycol) methacrylate (Mn = 360) solutions have been measured by the isopiestic method at 298.15 K. Sodium iodide and calcium chloride were used as the isopiestic standards for the calculation of activities. The original equation of Flory−Huggins and the modified Flory−Huggins equation with concentration-dependent interaction parameters have been used for the correlation of the experimental solvent activity data. The strength of interaction between different alcohols and the polymer was discussed on the basis of the obtained Flory−Huggins interaction parameters. The reliability of the two local-composition models, NRTL and NRF, were also assessed by fitting the experimental activity data to these models. All of these models satisfactorily present the obtained experimental activity data. ...

AU - Huang, T. H.. AU - Das Gupta, S. K.. AU - Griffin, R. G.. PY - 1982/7. Y1 - 1982/7. N2 - The temperature dependence of the 13C NMR spectra of dipalmitoylphosphatidylethanolamine (DPPE) and three lecithins-dimyristoyl-, dipalmitoyl-, and distearoylphosphatidylcholine- which have been 13C-labeled at the sn-2 carbonyl has been studied. In the Lg or Lp phase, an axially symmetric powder pattern of about 100-ppm breadth is observed, and this transforms to an isotropic line at the main Lβ (Lβ) →Lα phase transition. In the case of DPPE, this transformation occurs precipitously and, with data from 2H spectra of 2H chain labeled DPPE, is shown to be due to a change in conformation at the sn-2 carbonyl. In contrast, the 13C=0 sn-2 spectra of lecithins exhibit a gradual transformation, beginning at ...
The effect of sulphur on the phase equilibria of vesuvius phonolites : preliminary results. - INSU - Institut national des...
Crystallisation experiments have been performed on white phonolitic pumice samples of the Mercato (8010 BP), Avellino (3360 BP), Pompei (79 AD), and Pollena (472 AD) eruptions of Vesuvius to determine how the addition of sulphur to the system changes phase equilibria and compositions with respect to the sulphurfree system (experiments being undertaken by B. Scaillet and co-workers); the goal being to better constrain the pre-eruption conditions in the magma chamber preceding major phonolitic eruptions at Vesuvius, as well as to constrain the atmospheric sulphur yields of these eruptions. The experiments have been performed in an IHPV with a hydrogen membrane at 200 MPa, a maximum temperature of 930 °C, ƒO2 between NNO-4 and NNO+2, with 1 wt% S added to half of the capsules. Run durations were 6-10 days with an isobaric quench. The experimental products were identified by SEM and EMPA techniques. The addition of sulphur to the Avellino composition causes the appearance of sulphur-bearing scapolite and

Phase equilibria and thermodynamics of hydroxybenzoic acid isomers and salicylamide
Solution and solid-state properties of m-hydroxybenzoic acid have been investigated. Two polymorphs were found where the monoclinic modification exhibits a higher stability than the orthorhombic form. The solubility of the monoclinic polymorph was determined between 10 and 50 degrees C in methanol, acetonitrile, acetic acid, acetone, water and ethyl acetate. The solubility of the orthorhombic polymorph was determined between 10 and 50 degrees C in acetonitrile, acetic acid, acetone and ethyl acetate. A thermodynamic analysis revealed a marked correlation between the molar solubility and the vant Hoff enthalpy of solution at constant temperature. In addition, in each solvent increased temperature resulted in increased vant Hoff enthalpy of solution. It is shown that the solubility data can be used to estimate melting properties for both polymorphs. The solubility ratio of the two forms and the DSC thermogram of the orthorhombic form strongly suggest that the system is monotropic. However, ...

So now were starting to look at mixtures. And so now we have more than one constituent. And we have more than one phase present. Right? So youve started to look at things that look like this, where youve got, lets say, two components. Both in the gas phase. And now to try to figure out what the phase equilibria look like. Of course its now a little bit more complicated than what you went through before, where you can get pressure temperature phase diagrams with just a single component.

LABORATOIRE DE GENIE CHIMIQUE
Graphical shortcut methods are useful tools for the design of distillation columns. The proposed nonideal shortcut method includes a graphical representation and is based on the concept of operation leaves. This new method uses a production segment rather than a completely specified product, which eliminates any sensitivity to the composition of the minor product. Concerning phase equilibria, no restrictive assumptions are made. - The study aimed (1) to determine whether a specified separation respects the mass balance and thermodynamic feasibility and (2) to find the minimum reflux ratio for a preliminary design of the column. Designs obtained with this new method for ideal, non-ideal, and azeotropic mixtures give purity and recovery rates close to the specifications, which might be impossible to obtain with a conventional ideal shortcut like the well-known Fenske-Underwood-Gilliland shortcut method. The distillation boundaries of azeotropic mixtures are taken into account thanks to a non-ideal ...

Plasmaviridae - Wikipedia
Plasmaviridae is a family of bacteria-infecting viruses. Acholeplasma species serve as natural hosts. There are currently only one genus (Plasmavirus), and one species in this family: the type species Acholeplasma phage L2. All species known in this family have been isolated from species in the class Mollicutes. This family is poorly studied and little is known about these viruses. The family has one genus, Plasmavirus, which has one recognized member. There are five tentative members of Plasmavirus: Acholeplasma phage L2 (type species) Mycoplasmatales virus-laidlawii 1 (L1) (tentative) Mycoplasmatales virus-laidlawii 2 (L2) (tentative) Mycoplasmatales virus-laidlawii 3 (L3) (tentative) Mycoplasmatales virus-laidlawii 51 (L51) (tentative) Mycoplasmatales virus-laidlawii O1 (O1) (tentative) Group: dsDNA Order: Unassigned Family: Plasmaviridae Genus: Plasmavirus Acholeplasma phage L2 The genome is condensed, nonsegmented and consists of a single molecule of circular, supercoiled double-stranded ...

AU - Iwai, Yoshio. AU - Sasaki, Mitsuru. AU - Goto, Motonobu. PY - 2008/12/1. Y1 - 2008/12/1. N2 - Phase equilibrium data for methanol + C18 methyl esters and methanol + α-tocopherol were measured at 523-573 K in the pressure ranges of 2.45-11.45 MPa for C18 methyl esters and 3.19-15.02 MPa for α-tocopherol, respectively. The measured data were correlated using Peng-Robinson equation of state (PR EOS) with conventional mixing rules. The distribution coefficients of C18 methyl esters and α-tocopherol in methanol were discussed. The data illustrate that when the pressure is lower than the critical pressure of methanol (8.097 MPa), the mole fractions of methanol in vapor are very close to unity for both systems. When the pressure increased over 8 MPa, the distribution coefficients increased ...

ASMscience | Molecular Biology and Pathogenicity of Mycoplasmas
Mycoplasmas are unique microorganisms. They are the smallest known free-living and self-replicating prokaryotes and are distinct from gram-negative and gram-positive bacteria by the lack of a rigid cell wall. Mycoplasmas and bacterial L-forms reveal a similar colony appearance (i.e., a fried-egg colony morphology) but have no close relationship, as genomic analyses has shown. Mycoplasmas can be found in animals, humans, plants, and insects. Some mycoplasmas are well described as pathogens; others have been discussed as cofactors, opportunists, or commensals.

Investigation of Degradation Mechanisms of LSCF Based SOFC Cathodes - by CALPHAD Modeling and Experiments - DTU Orbit
The first part of the research work was devoted to establish a self-consistent thermodynamic database of relevant components (La-Sr-Co-Fe-O) using the CALPHAD (CALculation of PHAse Diagrams) approach. Published thermodynamic databases and experimental data related to the La-Sr-Co-Fe-O system were critically reviewed. The thermodynamic descriptions of the La-Co-O, Sr-Co-O and La-Sr-Co-O systems were further improved in order to construct the present thermodynamic database for LSCF, while new thermodynamic modeling of the Co-Fe-O, Sr-Co-Fe-O and La-Sr-Co-Fe-O systems was performed in this work. Calculated phase equilibria in LSCF as functions of composition, temperature, oxygen partial pressure are discussed by comparing with experimental data. Based on the developed thermodynamic database, the stability windows of LSC (La1−xSrxCoO3−δ) and LSCF are predicted and presented in Chapter 5 and Chapter 6, respectively. Calculations show that the perovskite phase is stable at high La and Fe ...

A Practical Fitting Method Involving a Trade-Off Decision in the Parametrization Procedure of a Thermodynamic Model and Its...
The design of processes containing information on phase equilibria must be carried out through a series of steps, experimentation ↔ verification ↔ modeling ↔ simulation. Each of these steps should be rigorously performed to guarantee a good representation of the behavior of the system under study, whose adequate modeling could be used to simulate the corresponding process. To carry out the different previous tasks, two representative systems, extracted from known database, are used. The quality checking of experimental data series is certified through several thermodynamic consistency methods. The modeling is done by applying a multi-objective optimization procedure, which allows to define a solution front (Pareto front) for different sub-models that are established in this work. The fitness of trade-off solutions, obtained from the efficient front, on the design of distillation processes is analyzed through a simulation.
