Nitrilase of Rhodococcus rhodochrous J1. Conversion into the active form by subunit association. (1/19)

Nitrilase-containing resting cells of Rhodococcus rhodochrous J1 converted acrylonitrile and benzonitrile to the corresponding acids, but the purified nitrilase hydrolyzed only benzonitrile, and not acrylonitrile. The activity of the purified enzyme towards acrylonitrile was recovered by preincubation with 10 mM benzonitrile, but not by preincubation with aliphatic nitriles such as acrylonitrile. It was shown by light-scattering experiments, that preincubation with benzonitrile led to the assembly of the inactive, purified and homodimeric 80-kDa enzyme to its active 410-kDa aggregate, which was proposed to be a decamer. Furthermore, the association concomitant with the activation was reached after dialysis of the enzyme against various salts and organic solvents, with the highest recovery reached at 10% saturated ammonium sulfate and 50% (v/v) glycerol, and by preincubation at increased temperatures or enzyme concentrations.  (+info)

Hyper-inducible expression system for streptomycetes. (2/19)

Streptomycetes produce useful enzymes and a wide variety of secondary metabolites with potent biological activities (e.g., antibiotics, immunosuppressors, pesticides, etc.). Despite their importance in the pharmaceutical and agrochemical fields, there have been no reports for practical expression systems in streptomycetes. Here, we developed a "P(nitA)-NitR" system for regulatory gene expression in streptomycetes based on the expression mechanism of Rhodococcus rhodochrous J1 nitrilase, which is highly induced by an inexpensive and safe inducer, epsilon-caprolactam. Heterologous protein expression experiments demonstrated that the system allowed suppressed basal expression and hyper-inducible expression, yielding target protein levels of as high as approximately 40% of all soluble protein. Furthermore, the system functioned in important streptomycete strains. Thus, the P(nitA)-NitR system should be a powerful tool for improving the productivity of various useful products in streptomycetes.  (+info)

Effect of high hydrostatic pressure on the barrier properties of polyamide-6 films. (3/19)

Little is known about the barrier properties of polymer films during high pressure processing of prepackaged foods. In order to learn more about this, we examined the influence of high hydrostatic pressure on the permeation of raspberry ketone (dissolved in ethanol/water) through polyamide-6 films at temperatures between 20 and 60 degrees C. Permeation was lowered by increasing pressure at all temperatures. At 23 degrees C, the increasing pressure sequence 0.1, 50, 100, 150, and 200 MPa correlated with the decreasing permeation coefficients P/(10(9) cm(2) s-1) of 6.2, 3.8, 3.0, 2.2, and 1.6. Analysis of the permeation kinetics indicated that this effect was due to a reduced diffusion coefficient. Pressure and temperature acted antagonistically to each other. The decrease in permeation at 200 MPa was compensated for by a temperature increase of 20 degrees C. After release of pressure, the former permeation coefficients were recovered, which suggests that this 'pressure effect' is reversible. Taken together, our data revealed no detrimental effects of high hydrostatic pressure on the barrier properties of polymer films.  (+info)

A new method for measuring free drug concentration: retinal tissue as a biosensor. (4/19)

PURPOSE: To develop a method of using isolated rat retina as a biosensor in experiments on controlled drug release for measuring the resultant concentration of free model drug in living tissue and for testing the biocompatibility of the polymers and polymeric nanostructures used as drug carriers. METHODS: The method is based on the monotonic dependence of the photoresponse kinetics of retinal rods on the concentration of the membrane-permeable phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (IBMX). Changes in the time to peak (tp) of linear-range rod photoresponses were followed by transretinal ERG mass potential recordings in the aspartate-treated, dark-adapted rat retina. The dependence of tp on [IBMX] was measured, and the calibration curve thus obtained was used to determine the amount of IBMX released from polymeric structures. The biocompatibility of the carrier was first assessed by the degree to which rods retained stable function in the presence of the polymer or monomers alone. RESULTS: The dependence of tp on [IBMX] was well-described by a second-order polynomial. After each change of [IBMX], a new equilibrium state was reached within 6 to 9 minutes, depending on temperature. The amounts of IBMX released from biocompatible polymeric structures were measurable with good accuracy in the range 10 to 300 microM. CONCLUSIONS: This method enables accurate concentration determinations of the model drug IBMX in retinal tissue in drug-release experiments. The concentration dependence of the photoresponse kinetics has to be calibrated for each retina and temperature. The same preparation can be used for rapid testing of possible bioincompatibility of various molecules.  (+info)

Temperature limit values for touching cold surfaces with the fingertip. (5/19)

OBJECTIVES: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. METHODS: Data were collected in four laboratories with a total of 20 males and 20 females performing a grand total of 1655 exposures. Each touched polished blocks of aluminium, stainless steel, nylon-6 and wood using the distal phalanx of the index finger with a contact force of 1.0, 2.9 and 9.8 N, at surface temperatures from +2 to -40 degrees C for a maximum duration of 120 s. Conditions were selected in order to elicit varying rates of skin cooling upon contact. Contact temperature (TC) of the fingertip was measured over time using a T-type thermocouple. RESULTS: A database obtained from the experiments was collated and analysed to characterize fingertip contact cooling across a range of materials and surface temperatures. The database was subsequently used to develop a predictive model to describe the contact duration required for skin contact temperature to reach the physiological criteria of onset of pain (15 degrees C), onset of numbness (7 degrees C) and onset of frostbite risk (0 degrees C). CONCLUSIONS: The data reflect the strong link between the risk of skin damage and the thermal properties of the material touched. For aluminium and steel, skin temperatures of 0 degrees C occurs within 2-6 s at surface temperatures of -15 degrees C. For non-metallic surfaces, onset of numbness occurs within 15-65 s of contact at -35 degrees C and onset of cold pain occurs within 5 s of contact at -20 degrees C. The predictive model subsequently developed was a non-linear exponential expression also reflecting the effects of material thermal properties and initial temperature. This model provides information for the protection of workers against the risk of cold injury by establishing the temperature limits of cold touchable surfaces for a broad range of materials, and it is now proposed as guidance values in a new international standard.  (+info)

High-yield activation of scaffold polymer surfaces to attach cell adhesion molecules. (6/19)

Zirconium tetra(tert-butoxide) reacts with surface amide groups of polyamide nylon 6/6 to give (eta(2)-amidate)zirconium complexes in high yield. These surface complexes react to bond the cell-adhesive peptide arginine-glycine-aspartic acid (RGD) to the polymer surface. A surface loading of 0.18 nmol/cm(2) of RGD is achieved, which is 20-1000 times higher than previously reported attainable on natural or synthetic polymers by other strategies. Approximately 40% of the nylon surface is covered by the RGD, which gives a surface that is both stable to hydrolysis and highly active for cell adhesion and spreading in vitro.  (+info)

Nylon-6 capillary-channeled polymer fibers as a stationary phase for the mixed-mode ion exchange/reversed-phase chromatography separation of proteins. (7/19)

Capillary-channeled polymer (C-CP) fibers extruded from nylon-6 are used as the stationary phase for the ion-exchange/reversed-phase mixed-mode chromatographic separation of a three protein mixture. The nylon-6 C-CP fibers are packed collinearly in a 250 x 1.5-mm i.d. column with an interstitial fraction of approximately 0.6. The effects of four displacing salts at three different pHs are studied with regards to protein retention time, peak width, selectivity, and resolution for a synthetic mixture consisting of myoglobin, ribonuclease A, and lysozyme to determine the optimum mobile phase conditions. The net charge model is found to be inadequate in fully explaining the retention behavior, as the proteins are retained by anion and cation-exchange interactions, as well as hydrophobic interactions with the stationary phase. It is found that pH and displacing salt strength had a significant influence on the retention properties and resolution of the proteins.  (+info)

The chemical works, owned by Nypro UK (a joint venture between Dutch State Mines (DSM) and the British National Coal Board (NCB)) had originally produced fertiliser from by-products of the coke ovens of a nearby steelworks. Since 1967, it had instead produced caprolactam, a chemical used in the manufacture of nylon 6.[a] The caprolactam was produced from cyclohexanone. This was originally produced by hydrogenation of phenol, but in 1972 additional capacity was added, built to a DSM design in which hot liquid cyclohexane was partially oxidised by compressed air. The plant was intended to produce 70,000 tpa (tons per annum) of caprolactam but was reaching a rate of only 47,000 tpa in early 1974. Government controls on the price of caprolactam put further financial pressure on the plant.[2] It was a failure of the cyclohexane plant that led to the disaster. A major leak of liquid from the reactor circuit caused the rapid formation of a large cloud of flammable hydrocarbon. When this met an ignition ...

A series of sidearm functionalized bisoxazoline ligands has been synthesized by reaction of the monolithiated methyl{bis(oxazolinyl)}methane with the appropriate electrophiles, and tested in the copper catalyzed asymmetric allylic oxidation of cyclohexene ("Kharasch-Sosnovski" reaction). The observed enantioselectivities were higher (up to 85% ee) than for the unfunctionalized bisoxazoline ("BOX") derivatives (ca. 60% ee). Regardless of the functional groups incorporated into the sidearm unit, the ees obtained for the different derivatives were essentially indistinguishable. This implies that the sidearms do not interfere directly in this reaction and only play an indirect role by virtue of their steric demand. Three of the copper complexes have been characterized by X-ray diffraction, establishing a distorted octahedral coordination geometry around the copper atom in all three cases. In the elongated distorted CuN2O4 octahedra, the two nitrogen atoms of the oxazolines and one oxygen atom of ...

Nanostructuring organic polymers and organic/inorganic hybrid materials and controlling blend morphologies at the molecular level are the prerequisites for modern electronic devices including biological sensors, light emitting diodes, memory devices and solar cells. To achieve all-around high performance, multiple organic and inorganic entities, each designed for specific functions, are commonly incorporated into a single device. Accurate arrangement of these components is a crucial goal in order to achieve the overall synergistic effects. We describe here a facile methodology of nanostructuring conjugated polymers and inorganic quantum dots into well-ordered core/shell composite nanofibers through cooperation of several orthogonal non-covalent interactions including conjugated polymer crystallization, block copolymer self-assembly and coordination interactions. Our methods provide precise control on the spatial arrangements among the various building blocks that are otherwise incompatible with one

Polymer recycle has been practiced as part of the manufacturing process for nylon-6,6 (219) and nylon-6 (220) almost from the beginning of the iadustry. Acid hydrolysis by Du Pont and base hydrolysis by BASF and Rhc ne-Poulenc of relatively pure nylon-6,6 waste streams, followed by separation of iagredients, purification, and reuse, has been practiced for many years. Also, phosphoric acid-cataly2ed hydrolysis and steam distillation of caprolactam from pure nylon-6 is still used by BASF, Rhc ne-Poulenc, and SNIA. However, it is the challenge of recycling post-consumer waste that has generated the greatest activity siace 1990. Stimulated by more stringent governmental regulations for recycling plastic packagiag and automotive plastic components la Germany and the growing landfill problem ia the United States, the nylon iadustry has developed several technologies to address the issue of recycling post-consumer waste. One of the greatest economic challenges is the collection and separation of nylon ...
In Paramecium, small granular particles are present in the cytoplasm called as kappa particles. Kappa particles produce a protein called paramecin that kills the sensitive strain without kappa particles. The strain with the kappa particles is called as killer/resistant strain and the other strain is called as sensitive strain. Gene responsible for producing kappa particles is present in homozygous or heterozygous dominant condition in killer strain while it is present in recessive form in sensitive strain. Paramecium reproduces both by sexual and asexual mode. During asexual reproduction, when conditions favour the cells undergo cell division while the kappa particles cannot divide at the same rate. Therefore the daughter cells receive less number of kappa particles and after few generations there can be complete loss of kappa particles. In this situation, strains with dominant alleles remain without any kappa particles. This proves the gene for kappa particles can only help in multiplication of ...

FRANKFURT, Germany (AP) ? Chemicals and oil company BASF SE warned Thursday that it will find it more difficult to achieve its full-year profit target as it reported a 4.2 percent fall in second-quarter earnings due to weaker demand in an uneven global economy.. Following the warning, BASF shares fell 4 percent to 67.09 euros in morning trading in Frankfurt.. Net profit fell 4.2 percent to 1.16 billion euros ($1.53 billion) even as revenues rose 2.9 percent to 18.35 billion euros.. The company, based in Ludwigshafen, Germany, said it saw thinner profit margins on some products in its basic chemicals division such as caprolactam, the raw material for a widely used form of nylon that goes into everything from lingerie to tires.. It also said its business in more extensively processed chemical products saw "intense competition in some product lines." That division also saw euro earnings reduced by a weaker yen, while its year-earlier earnings were boosted by insurance payments for damage suffered ...

Kosterlitz and Thouless (and independently Berezinskii) were looking at the problem of phase transitions in two dimensions of a certain type. As an example, imagine a huge 2d array of compass needles, each free to rotate in the plane, but interacting with their neighbors, so that neighbors tend to want to point the same direction. In the low temperature limit, the whole array will be ordered (pointing all the same way). In the very high temperature limit, when thermal energy is big compared to the interaction between needles, the whole array will be disordered, with needles at any moment randomly oriented. The question is, as temperature is increased, how does the system get from ordered to disordered? Is it just a gradual thing, or does it happen suddenly in a particular way? It turns out that the right way to think about this problem is in terms of vorticity, a concept that comes up in fluid mechanics as well (see this wiki page with mesmerizing animations). Its energetically expensive to ...

Two new UiO-68 type of Zr-MOFs featuring redox non-innocent catechol-based linkers of different redox activities have been synthesized through a de novo mixed-linker strategy. Metalation of the MOFs with Cu(II) precursors triggers the reduction of Cu(II) by the phenyl-catechol groups to Cu(I) with the concomitant formation of semiquinone radicals as evidenced by EPR and XPS characterization. The MOF-supported catalysts are selective toward the allylic oxidation of cyclohexene and it is found that the presence of in situ-generated Cu(I) species exhibits enhanced catalytic activity as compared to a similar MOF with Cu(II) metalated naphthalenyl-dihydroxy groups ...
Eukaryotic protein‐coding genes are typically classified into two groups: those with expression regulated by specific signals versus the relatively constant "housekeeping" genes. Although these differences are associated with alternative modes of RNA polymerase II (RNAP II) pre‐initiation complex (PIC) assembly, a role for gene‐specific activators in controlling "regulatability" has been difficult to rule out. To address this question, de Jonge et al (2017) studied a group of genes controlled by a common activator but dependent on either TFIID or SAGA and found that the magnitude of regulation strongly correlates with the mechanism of PIC assembly..

Frustrated and disappointed, I decided to listen to my body and simply proceed to the wod: 10 rounds of 10 kettlebells @40# and 10 toes-to-bar (I realize this is unfamiliar territory for my family, but instead of me listing definitions for everything, you can always ask if you dont understand something). I figured the entire wod would easily take under 15 minutes. After the second round, I was seriously considering quitting. I felt dizzy. Out of breath. I had plenty of strength, but all I could do was stare at that bar and say, "No way. Im not jumping up there." Id lean against the wall and press my face to the nice cold surface, practically praying to it, "Thank you, cement wall. Thank you for being cold and comforting my 42-year-old body in this time of need." Then Id take a deep breath and keep attacking the wod. I promised myself that if I could make it to five rounds, Id quit then. But before I got that far, I vowed I would finish the workout if it took an entire hour. Ive never quit ...
19th July 2017. Something in Shade was spinning, replaying events that had already passed. It liked doing that but it usually stuck to his childhood. Which was why his eyes widened.. Grubby features fixed themselves on him. They looked like they could once have been plump yet they had, over time, acquired a lesser stuffing. It wasnt the weight that scared him - that wouldve been hypocritical with a mother who had been skinny and an uncle who had sworn he had a beer belly. No, there was something wrong with it. Something so drastically wrong that he heard Vic gag behind him as she rose to her feet.. He gasped for air, his neck arching and his head making contact with a cold surface beneath him. As his chest heaved, the rest of his body was paralysed. The brief moments he left the state of spinning over and over were like the snippets of time a drowning man had with his mouth above the water.. The man with the grubby face let out a low sound and pressed his mottled skin up close. Thought we ...

The study compared the biosensing properties of laccase biosensors based on carbon nanofibers (CNFs) and copper/carbon composite nanofibers (Cu/CNFs). The two kinds of nanofibers were prepared by electrospinning and carbonization under the same conditions. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy were employed to investigate the morphologies and structures of CNFs and Cu/CNFs. The amperometric results indicated that the Cu/CNFs/laccase(Lac)/Nafion/glass carbon electrode (GCE) possessed reliable analytical performance for the detection of catechol. The sensitivity of the Cu/CNFs/Lac/Nafion/GCE reached 33.1 μA/mM, larger than that of CNFs/Lac/Nafion/GCE. Meanwhile, Cu/CNFs/Lac/Nafion/GCE had a wider linear range from 9.95 × 10−6 to 9.76 × 10−3 M and a lower detection limit of 1.18 μM than CNFs/Lac/Nafion/GCE. Moreover, it exhibited a good repeatability, reproducibility, selectivity and long-term stability, revealing that electrospun Cu/CNFs have great

Handmade cloning (HMC) has been used to generate transgenic pigs for biomedical research. Recently, we found that parthenogenetic activation (PA) of porcine oocytes and improved HMC efficiency could be achieved by treatment with sublethal high hydrostatic pressure (HHP). However, the molecular mechanism underlying the effects of HHP treatment on embryonic development is poorly understood and so was investigated in the present study. Thus, in the present study, we undertook genome-wide gene expression analysis in HHP-treated and untreated oocytes, as well as in 4-cell and blastocyst stage embryos derived by PA or HMC. Hierarchical clustering depicted stage-specific genomic expression profiling. At the 4-cell and blastocyst stages, 103 and 163 transcripts were differentially expressed between the HMC and PA embryos, respectively (P , 0.05). These transcripts are predominantly involved in regulating cellular differentiation, gene expression and cell-to-cell signalling. We found that 44 transcripts ...
Xenopus laevis embryos of stages 14-20 were subjected, for periods of 5-330 min, to hydrostatic pressures ranging from 500 to 10000 psi. The specimens were fixed under corresponding pressures and their neuroepithelium was studied under light and electron microscopy. A pressure of 3000 psi, maintained for as long as 180 min, did not inhibit neurulation though it induced slight deformities of the neuroepithelium. A pressure of 4000 psi, applied for 180 min, disrupted the apical ring of microfilaments and blocked neurulation. The cells lost their dissymmetry. The effect was reversible. Lengthening the duration of treatment to 330 min caused the neuroepithelial cells to loose their microtubules and to become round. This situation was not reversible. Our results indicated that microfilaments are more sensitive than microtubules, that both organelles became increasingly sensitive as the exerted pressure was increased and that microtubules of older embryos exhibited a better resistance. Finally, we ...
Extractables can be diverse. No single analytical method can detect all extractables, so multiple orthogonal methods must always be used. The table below summarizes analytical techniques and their ability to detect diverse chemical entities extracted from materials.. Liquid chromatography and gas chromatography are two analytical separation techniques that, when applied together, provide the ability to detect diverse extractables. The use of alternate sample introduction techniques (e.g. headspace analysis) and detectors (e.g. flame ionization detector) increases the range of detectable extractables.. In addition, sample modification techniques can provide the ability to more effectively detect specific types of extractables. For example, organic acids are often more easily detected by GC following sample derivatization.. The different techniques employed by VR Analytical are briefly described below. When a combination of these techniques is applied, a more complete characterization of the ...
Electrospinning is a versatile method to fabricate nanofibers of a range of polymeric and composite materials suitable as scaffolds for tissue engineering applications. In this study, we report the fabrication and characterization of polyaniline-carbon nanotube/poly(N-isopropyl acrylamide-co-methacrylic acid) (PANI-CNT/PNIPAm-co-MAA) composite nanofibers and PNIPAm-co-MAA nanofibers suitable as a three-dimensional (3D) conducting smart tissue scaffold using electrospinning. The chemical structure of the resulting nanofibers was characterized with FUR and H-1 NMR spectroscopy. The surface morphology and average diameter of the nanofibers were observed by SEM. Cellular response of the nanofibers was studied with mice L929 fibroblasts. Cell viability was checked on 7th day of cell culture by double staining the cells with calcein-AM and PI dye. PANI-CNT/PNIPAm-co-MAA composite nanofibers were shown the highest cell growth and cell viability as compared to PNIPAm-co-MAA nanofibers. Cell viability in ...

Batch processiag of nylon-6 is generally used only for the production of specialty polymers such as very high molecular weight polymer or master batch polymers for special additives. In a typical modem batch process (147-150), the caprolactam is mixed ia a hoi ding tank with the desired additives and then charged to an autoclave with a small amount (2-4%) of water. During the two-stage polymeriza tion cycle, the temperature is raised from 80 to 260°C. In the first stage, water is held ia the reactor, the pressure rises, and the hydrolysis and addition steps occur. After a predetermined time the pressure is releasedand the final condensation reaction step occurs. The molecular weight of the polymer can be iacreased by means of a vacuum finishing step, if desired. The entire process can take three to five hours. The final polymer is then drained, often with a forcing pressure of iaert gas, through a die to form ribbons of polymer, which are then cooled ia water and cut iato pellets. Because ...
Cyclohexanone oxime is used primarily as a captive intermediate in the synthesis of caprolactam for the production of polycaprolactam (Nylon-6) fibers and plastics and also in a variety of industrial applications. Cyclohexanone oxime was selected for study because of the potential for human exposure and the interest in oximes as a chemical class. Toxicity studies of cyclohexanone oxime (approximately 99% pure) were carried out in male and female B6C3F1 mice; the compound was administered in drinking water for 2 weeks or 13 weeks. In addition, the genetic toxicity of cyclohexanone oxime was evaluated by determining mutagenicity in Salmonella typhimurium and induction of chromosomal aberrations in cultured Chinese hamster ovary cells in vitro, with and without S9 activation. The frequency of micronucleated normochromatic erythrocytes in the bone marrow and peripheral blood of mice from the 13-week study was also determined.. In the 2-week study, groups of five male and five female mice were given ...
Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films or shapes. Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1930. The first example of nylon (nylon 6,6) was produced using diamines on February 28, 1935, by Wallace Carothers at DuPonts research facility at the DuPont Experimental Station. In response to Carothers work, Paul Schlack at IG Farben developed nylon 6, a different formulation based on caprolactam, on January 29, 1938. Nylon was first used commercially in a nylon-bristled toothbrush in 1938, followed more famously in womens stockings or "nylons" which were shown at the 1939 New York Worlds Fair and first sold commercially in 1940. During World War II, almost all nylon production was diverted to the military for use in parachutes and parachute cord. Wartime uses of ...
Phenol ranked 38th in production among U.S. chemicals in 1978 with annual production of 2.38 billion pounds. Approximately 90% of the phenol produced is used in the manufacture of phenolic (phenol formaldehyde) resins, caprolactam, bisphenol A, alkyl phenol, and adipic acid. The remainder of the phenol is used to produce an assortment of end products, including salicylic acid, phenacetin, dyes, metal cleaners, disinfectants, antiseptics, photographic chemicals, wood preservatives (pentachlorophenol), paints, paint and varnish removers, and agricultural chemicals (2,4-D and parathion).. A bioassay of phenol to test for possible carcinogenicity was conducted by providing this substance in drinking water to F344 rats and B6C3F1 mice. Groups of 50 rats and 50 mice of each sex were given drinking water containing 2,500 or 5,000 ppm phenol for 103 weeks. As matched controls, groups of 50 rats and 50 mice of each sex received tap water.. A dose-related depression in mean body weight gain occurred in ...
Dry lubricants can be classified into solid lubricants in powder form, ceraceous sliding films and in bonded coatings containing solids. Bonded coatings are solid lubricants (usually MoS2, graphite or PTFE) that are incorporated into an organic or inorganic binder. In order to allow distribution of the bonded coating, a solvent which evaporates during the hardening or drying time is added. After thorough preparation of the surface, coating is carried out by means of immersion, spraying or painting. ...
DNA topoisomerases are enzymes that control DNA topology and are vital targets for antimicrobial and anticancer drugs. Here we present a mass spectrometry study of complexes formed between the A subunit of the topoisomerase DNA gyrase and the bifunctional inhibitor simocyclinone D8 (SD8), an antibiotic isolated from Streptomyces. These studies show that, in an alternative mode of interaction to that found by X-ray crystallography, each subunit binds a single bifunctional inhibitor with separate binding pockets for the two ends of SD8. The gyrase subunits form constitutive dimers, and fractional occupancies of inhibitor-bound states show that there is strong allosteric cooperativity in the binding of two bifunctional ligands to the dimer. We show that the mass spectrometry data can be fitted to a general model of cooperative binding via an extension of the "tight-binding" approach, providing a rigorous determination of the dissociation constants and degree of cooperativity. This general approach ...
In 2007, only 5,000 bbl/d of crude and 71,000 bbl/d of petroleum products, including fuel ethanol, moved on tankers and barges from the Midwest to the Gulf Coast. The growth in waterborne movements began in 2010 and was driven by increases in product movements because Midwest refineries with access to discounted crude oil increased the volume of crude oil processed; however, with limited product pipeline capacity from PADD 2 to PADD 3, those refineries turned to alternative modes of transportation to move their products. The growth in 2011 and 2012 waterborne shipments was driven by crude oil movements as production of crude oil in PADD 2 outpaced pipeline capacity growth and producers looked for alternative ways to move growing crude oil volumes to refining centers on the U.S. Gulf Coast ...
The report establishes a theoretical framework and computational procedures which lead to an experimental strategy for distinguishing between two alternative modes of operation of the vestibular statoreceptors: the question is whether individual kinocilia in the maculae sacculi and utriculi are innervated by single vestibular afferent fibers; or else, whether convergence of neural discharges originating from several kinocilia with different orientation of functional polarization occurs in vestibular afferent fibers. If the former condition prevails, it is possible to calculate the vector of maximal sensitivity of each kinocilium from the polar plot of nerve discharge rates, obtained at suitable head positions in the gravity field. The principle of the procedure consists in the matching of experimental data with a computer simulated model of sacculus and utriculus. (Author)(*MEDICAL EQUIPMENT
In principle, the manufacturing process of films for use in biopharmaceutical applications is comparable to that of films for use in food packaging, says Schnellenbach. Pharmaceutical suppliers also have to adhere to precisely defined controlled production processes that are subject to defined change control. This also applies to the formulation of the granules from which the films are extruded at the company site in Ochsenhausen. The supply chain and secure supply of identical granules, documentation, marketing authorisation procedure and the accompanying measurements throughout the controlled production processes have to meet pharmaceutical industry standards.. Safety is the key to biopharmaceutical development and production. So-called extractables and leachables that can migrate from the polymer material into the active ingredients are considered the greatest of all potential risks. Extractables are compounds that can migrate from polymers over a prolonged period of time, at high ...
It had been proposed that superfluidity could coexist with crystalline order in solid helium, thanks its quantum properties. If true, solid helium would have been be the first "supersolid". For some years, one thought that this paradoxical coexistence of order in real and momentum space - named "supersolidity" - had been observed by several groups in the world. But nowadays, we understand that supersolidity does not exist in these crystals, but instead the mobility of their dislocations is so high in the low temperature limit and if all impurities are suppressed, that it does not resist to shear in some directions. The discovery of this "giant plasticity" in helium crystals is not less interesting than supersolidity. Its careful analysis has led to fundamental progress in the knowledge of dislocation networks and dynamics, which are basic phenomena at the origin of the plasticity of materials. Now a question remains: in the end, what is really quantum in these crystals? I will try to give some ...
Comments: 78 Pages.. Nylon comprises a family of man-made substances that were first manufactured in 1935. Nylonases are biological enzymes that can break down nylon oligomers. Although the most prominent nylonases are within the family of enzymes classified as 6-aminohexanoate hydrolases, some enzymes not formally classified as 6-aminohexanoate hydrolases also have the ability to breakdown nylons, and so can also be classified as nylonases. Organisms that encode a nylonase enzyme do not necessarily have the ability to actually survive on a nylon substrate as their sole carbon source. Among the first documented organisms that did have this ability was the soil bacterium Arthrobacter KI72. It has long been thought that nylonase genes and proteins were essentially absent from the biosphere prior to 1935. This belief led to the widespread assumption that any nylonase gene observed in the present must have emerged since 1935. Several authors developed hypothetical models of how a specific nylonase ...

Several additive manufacturing processes have been developed for plastic parts. However, there is an ongoing interest to increase the functionality of these parts which are mainly considered as prototypes due to the material and process limitations. This research investigated a novel additive approach for producing a functional engineering plastic, nylon 6. The idea was to combine inkjet printing technology and anionic polymerisation of caprolactam by depositing mixtures of caprolactam with activator and catalyst on top of each other under the appropriate conditions. An experimental setup was integrated based on two identical jetting assemblies with pneumatic and thermal control, synchronised with a deposition system for the reaction of the mixtures upon radiation heating. Different offline material characterisation and inline process monitoring methods were employed to obtain an understanding of the material behaviour at each stage of the research. These included the use of high speed imaging, ...

Capsaicinol is an ingredient of hot red pepper. In this study, we developed a novel method for capsaicinol synthesis and examined capsaicinols physiological effects on capsaicin receptor (TRPV1)-related actions. Allylic oxidation of capsaicin by palladium acetate (Pd(OAc),SUB,2,/SUB,) resulted in the formation of (±)-capsaicinol acetate at a 7.2% yield in a single step. The effectiveness of (±)-capsaicinol in TRPV1 activation (EC,SUB,50,/SUB,=1.1 μ,small,M,/small,) was found to be weaker than that of capsaicin (EC,SUB,50,/SUB,=0.017 μ,small,M,/small,), whereas the efficacy of (±)-capsaicinol reached 75% of that of capsaicin. Intravenous administration of (±)-capsaicinol in anesthetized rats dose-dependently enhanced adrenaline secretion from the adrenal gland. The response to a 5 mg/kg-dose of (±)-capsaicinol was comparable to that of a 0.05 mg/kg-dose of capsaicin. The relative pungency of capsaicinol to capsaicin was coincident with the relative effectiveness in inducing these ...

Longstanding beliefs about how children read accentuate the importance of phonological processing in mapping letters to sound. However, when one considers the nature of the script being read, the process can be far more complicated, particularly in the case of an alphabetic script like English (Share, 2008). Cross-cultural reading research reveals alternative modes of processing text that is not entirely phonological. Chinese is known for its non-alphabetic script and its greater reliance upon morphological processing (Anderson & Kuo, 2006), visual skills (Ho & Bryant, 1997; Huang & Hanley, 1995; McBride-Chang & Zhong, 2003), and radical awareness- all argued to be essential skills in deciphering the character-based script. Given the more visual and semantic structure of Chinese, would reading Chinese be easier for deaf students than a sound-based system like English? Deaf readers in China are nevertheless required to learn two very different scripts- one alphabetic (Pinyin) and another ...

Although leaky roofs, poor flashings, inadequate sidewall construction, and plumbing leaks are common sources of excessive moisture in homes and other buildings, condensation within buildings has become a more important factor in much of the United States. Condensation problems are obviously different in cold and temperate regions from those in warm, humid ones. Cold-weather condensation is most likely to occur in North America north of 370 latitude (excluding the Pacific Coast strip) where the average January temperature is below 35 ۶ (17 ۳). In this region, temperature differential results in vapor pressure inside a house being several times higher than outside, so that moisture tends to move outward through cracks, crevices, and building materials, and is most likely to condense on some cold surface, such as the outside face of sheathing, the back and inside faces of siding, on the undersides of roofs, and on chimmneys. The moisture generally condenses in the form of ice or frost. The frost ...
Stale air is typically exhausted from the kitchen and the bathrooms, since these areas have a high concentration of moisture. Moisture is a primary indoor air pollutant, and frequently needs to be removed. Other pollutants, such as carbon dioxide, cooking odors, and smoke, also need to be purged, but moisture remains a key "indicator" pollutant. When water is seen to condense on cold surfaces such as window panes, the relative humidity is too high in the house and the rate of ventilation (measured in whole house air changes per hour or ACH) must be increased. As a rule of thumb, for proper air quality, most SI houses require 1/3 ACH, or 10-20 CFM (cubic feet per minute) per person when occupied ...

Wall Tie corrosion is a problem particularly common in older brick properties with cavity walls. Condensing moisture in buildings always migrates to cold surfaces and since the Wall Ties are steel, moisture gathers on them. Over time they corrode until eventually they fail completely rendering the wall structurally unstable. In several cases this has led to building collapse.Book in a survey to check the structure and condition of your wall ties. Cavity wall design incorporating metal wall ties, has been in use since the beginning of the nineteenth century, to prevent rain penetration and to improve thermal insulation. Over recent years, it has become apparent that a high number of properties, built before 1981 are suffering from premature wall tie corrosion.. Latest research by the Building Research Establishment, has found that wall ties corrode faster in the mortar within the external leaf of brickwork, leading to oxidisation where they will expand to several times their original size. This ...

Polyvinyl alcohol (PVA) nanofibers and single-walled carbon nanotube (SWNT)/PVA composite nanofibers have been produced by electrospinning. An apparent increase in the PVA crystallinity with a concomitant change in its main crystalline phase and a reduction in the crystalline domain size were observed in the SWNT/PVA composite nanofibers, indicating the occurrence of a SWNT-induced nucleation crystallization of the PVA phase. Both the pure PVA and SWNT/PVA composite nanofibers were subjected to the following post-electrospinning treatments: (i) soaking in methanol to increase the PVA crystallinity, and (ii) cross-linking with glutaric dialdehyde to control the PVA morphology. Effects of the PVA morphology on the tensile properties of the resultant electrospun nanofibers were examined. Dynamic mechanical thermal analyses of both pure PVA and SWNT/PVA composite electrospun nanofibers indicated that SWNT-polymer interaction facilitated the formation of crystalline domains, which can be further ...

Low temperature performance affects the geographical distribution of insects. The lower critical temperature limits of chill-susceptible insects are likely determined by failure of ion and water balance at low temperature. I used phenotypic plasticity in the cold tolerance of Gryllus pennsylvanicus, and the naturally higher cold tolerance of Gryllus veletis to test the hypothesis that variation in low temperature performance is accompanied by variation in ion and water homeostasis at low temperatures. Low temperature acclimation and cold adaptation enhanced performance at low temperatures. Groups with higher cold tolerance had an enhanced ability to prevent or mitigate the migration of hemolymph Na+ and water into the digestive system, which ultimately resulted in smaller decreases in K+ equilibrium potentials at the muscle tissue. The ability to maintain ion and water balance as a result of changes in gut membrane permeability increased performance at low temperatures, and reduced the onset of chilling
