Zur Bestimmung der Detektorakzeptanz wurde eine modellabhaengige Simulationsrechnung mit dem Programm SAPHIR-GEANT durchgefuehrt. Das benutzte Modell basiert auf dem Zuschauermodell mit einem starken Einfluss des Kontaktgraphen {gamma}d {yields} n{sub s}{Delta}{sup ++}{pi}{sup -}. Die im Modell verwendete Winkelverteilung fuer den Zerfall der {Delta}-Resonanz ist in Anlehnung an aeltere Messungen am Proton mit W(cos{theta}) = 5 - 3 * cos{sup 2}{theta}) angenommen worden. Mit diesem Modell konnten die gemessenen Daten gut beschrieben werden.

Polypyrrole (PPy)/cobalt (Co) nanocomposites were successfully prepared by an in-situ polymerization of pyrrole in the presence of synthesized Co nanoparticles. Characterization of the product was accomplished by XRD, TEM, FT-IR, VSM, and vector network analyzer techniques. XRD analysis revealed that characteristic diffraction peaks of polypyrrole and Co appeared at the same time in nanocomposites. FT-IR analysis indicated a successful conjugation of Co particles with polypyrrole. TEM confirmed the formation of a core-shell structure with a wide particle size distribution. Magnetization measurements showed that polypyrrole coating decreased the saturation magnetization of Co significantly. With the increase of the matching thickness, the absorption peak varied towards low frequency direction. When the matching thickness was 3.0 mm, the value of the maximum reflection loss (RL) was −20.0 dB at 13.8 GHz with the 7.2 GHz bandwidth. - Highlights: • The influence of PPy on the structure of Co is discussed. • The influence of PPy on the magnetic properties of Co is discussed. • The influence of PPy on the absorption property of Co is discussed. • PPy/Co possessed the excellent absorption property.

With Low-Temperature-Electron-Microscopy (LTSEM) it is possible to analyse the transport properties of solids at low temperatures. In particular it is possible to image the supercurrent density j{sub s} in Josephson junctions. This was demonstrated by comparing TTREM-images with calculated values for j{sub s}. In this thesis ramp-type Nd{sub 2-x}Ce{sub x}CuO{sub 4-y}/Nb-Josephson-junctions (NCCO/Nb) and Josephson junctions with a ferromagnetic interlayer Nb/Al-Al{sub 2}O{sub 3}/NiCu/Nb, so-called SIFS (superconductor-insulator-ferromagnet-superconductor) Josephson junctions were studied.It was demonstrated that LTSEM provides direct imaging of the sign change of the order parameter in superconductors with d{sub x{sup 2}-y{sup 2}}-symmetry. This was a controversial issue over the last decade. A step like variation in the thickness of the F-layer allows the fabrication of linear and annular Josephson junctions with different numbers of 0 and {pi} facets. With the LTSEM 0-, {pi}-, 0-{pi}-, 0-{pi}-0-, 0/2-{pi}-0/2-, 20 x (0-{pi})- as well as square-shaped-, circular- and annular-Josephson-junctions were studied. It was demonstrated, that these junctions are of good quality and have critical current densities up to 42 A/cm{sup 2} at T=4.2 K, which is a record value for SIFS junctions with a NiCu F-layer so far. By comparing the measurements with simulations a first indication of a semifluxon at the 0-{pi}-boundary was found. (orig.)

Simultaneous in situ reduction of hexachloroplatinic acid by the amine group in the pyrrole monomer and oxidation of pyrrole to form polypyrrole (PPy) was examined. The reactions were performed at various temperatures to understand the degree of reduction of platinum precursor as well as doping of polypyrrole with Pt(II) chloro-complex. Spectroscopic images revealed different morphologies for the Pt/PPy nano-composite prepared at various temperatures. The as-prepared Pt/PPy nano-composite samples were tested for their ability to sense liquefied petroleum gas (LPG) which resulted in excellent sensing at relatively low temperature. The porous nature and ohmic contact between the PPy and platinum nanoparticles makes the as-prepared Pt/PPy nano-composite highly useful for sensors as well as electronic applications.

Allergic diseases are characterized by an increased production of specific IgE antibodies. Suppression of IgE antibody production may be accomplished through idiotypic manipulation. Using an animal model, we explored the effects of anti-Lol pI monoclonal antibody administration on the subsequent IgE and IgG antibody response against Lol pI. Mice were treated with an anti-Lol pI monoclonal antibody (290A-167), which resulted in the production of anti-idiotypic antibodies as evidenced by their ability to bind to the Fab fraction of 290A-167 and to inhibit the binding of rabbit polyclonal anti-idiotypic antibodies to 290A-167. The animals were then immunized with Lol pI adsorbed onto alum, and the immune response to the protein was analyzed. Antigen-specific IgG1 and IgE responses were strongly suppressed as determined by immunoassay. Suppression of anti-Lol pI IgE antibodies was confirmed by a reduction of end-point titers measured by passive cutaneous anaphylaxis. The suppression of antigen-specific antibody was accompanied by a reduction of anti-Lol pI antibody-producing spleen cells. These data indicate that pretreatment with 290A-167 can strongly downregulate the IgE response to the main allergen of ryegrass pollen, which is associated with an increase in anti-idiotypic antibodies. This approach could provide rapid, long-term hyposensitization in patients with grass pollen allergy.

Molecular species analysis of phosphatidylinositol (PI), phosphatidic acid (PA) and diacylglycerol (DG) in rat mast cells

The metabolism of DG, PA and PI were studied in purified rat mast cells to determine whether generally accepted pathways of PI metabolism could explain the pattern of fatty acids seen in these intermediates. A method was developed to separate and quantitate by mass (for DG) or endogenous labeling (for PA and PI) the different molecular species of each lipid that are defined by their component fatty acids. The resultant molecular species fingerprint for each lipid was examined to see if it was similar to other intermediates in the PI cycle. For each class of compounds the percent in a given subclass was recorded. Stimulation caused a reduction of more saturated subclasses and/or an increase in AA containing compounds in PA, PI and DG. The relative similarity of subclasses of 32 P-PA and 32 P-PI supports the view that they are metabolically related. The relative absence of AA-containing species of DG suggests that most of the stimulated increase of DG was not produced by PI hydrolysis

In some fields of fMRI data analysis, using correct methods for dealing with noise is crucial for achieving meaningful results. This paper provides a quantitative assessment of the effects of different preprocessing and noise filtering strategies on psychophysiological interactions (PPI) methods for analyzing fMRI data where noise management has not yet been established. Both real and simulated fMRI data were used to assess these effects. Four regions of interest (ROIs) were chosen for the PPI analysis on the basis of their engagement during two tasks. PPI analysis was performed for 32 different preprocessing and analysis settings, which included data filtering with RETROICOR or no such filtering; different filtering of the ROI "seed" signal with a nuisance data-driven time series; and the involvement of these data-driven time series in the subsequent PPI GLM analysis. The extent of the statistically significant results was quantified at the group level using simple descriptive statistics. Simulated data were generated to assess statistical improvement of different filtering strategies. We observed that different approaches for dealing with noise in PPI analysis yield differing results in real data. In simulated data, we found RETROICOR, seed signal filtering and the addition of data-driven covariates to the PPI design matrix significantly improves results. We recommend the use of RETROICOR, and data-driven filtering of the whole data, or alternatively, seed signal filtering with data-driven signals and the addition of data-driven covariates to the PPI design matrix.

Regulation of PI-2b Pilus Expression in Hypervirulent Streptococcus agalactiae ST-17 BM110.

Directory of Open Access Journals (Sweden)

Bruno Périchon

Full Text Available The widely spread Streptococcus agalactiae (also known as Group B Streptococcus, GBS "hypervirulent" ST17 clone is strongly associated with neonatal meningitis. The PI-2b locus is mainly found in ST17 strains but is also present in a few non ST17 human isolates such as the ST-7 prototype strain A909. Here, we analysed the expression of the PI-2b pilus in the ST17 strain BM110 as compared to the non ST17 A909. Comparative genome analyses revealed the presence of a 43-base pair (bp hairpin-like structure in the upstream region of PI-2b operon in all 26 ST17 genomes, which was absent in the 8 non-ST17 strains carrying the PI-2b locus. Deletion of this 43-bp sequence in strain BM110 resulted in a 3- to 5-fold increased transcription of PI-2b. Characterization of PI-2b promoter region in A909 and BM110 strains was carried out by RNAseq, primer extension, qRT-PCR and transcriptional fusions with gfp as reporter gene. Our results indicate the presence of a single promoter (Ppi2b with a transcriptional start site (TSS mapped 37 bases upstream of the start codon of the first PI-2b gene. The large operon of 16 genes located upstream of PI-2b codes for the group B carbohydrate (also known as antigen B, a major constituent of the bacterial cell wall. We showed that the hairpin sequence located between antigen B and PI-2b operons is a transcriptional terminator. In A909, increased expression of PI-2b probably results from read-through transcription from antigen B operon. In addition, we showed that an extended 5' promoter region is required for maximal transcription of gfp as a reporter gene in S. agalactiae from Ppi2b promoter. Gene reporter assays performed in Lactococcus lactis strain NZ9000, a related non-pathogenic Gram-positive species, revealed that GBS-specific regulatory factors are required to drive PI-2b transcription. PI-2b expression is up-regulated in the BM110ΔcovR mutant as compared to the parental BM110 strain, but this effect is probably

Land use type and managing method which is greatly influenced by human activities, is one of the most important factors of non-point pollution. Based on the collection and analysis of non-point pollution control methods and the concept of the three ecological fronts, 9 land use optimized scenarios were designed according to rationality analysis of the current land use situation in the 3 typed small watersheds in Miyun reservoir basin. Take Caojialu watershed for example to analyze and compare the influence to environment of different scenarios based on potential pollution index (PPI) and river section potential pollution index (R-PPI) and the best combination scenario was found. Land use scenario designing and comparison on basis of PPI and R-PPI could help to find the best combination scenario of land use type and managing method, to optimize space distribution and managing methods of land use in basin, to reduce soil erosion and to provide powerful support to formulation of land use planning and pollution control project.

POC polymer is an oxadiazole-carbazole copolymer we have previously synthetized and established as light emitting material in Organic Light Emitting Devices (OLEDs), although POC quantum yield emission efficiency and color purity still need to be enhanced. On the other hand, tris[2-phenylpyridinato-C2,N]iridium(III) (Ir(ppy)3) complexes, namely Ir(ppy)3 are among the brightest luminophores employed in green light emitting devices. Our aim, in this work, is to take advantage of Ir(ppy)3 bright emission by combining the Ir complex with blue emitting POC to obtain tunable light emitting composites over a wide range of the visible spectrum. Here we have investigated the optical proprieties POC based nanocomposites with different concentrations of Ir(ppy)3, ranging from 1 to 10 wt%. Both spectral and time resolved fluorescence measurements show an efficient energy transfer from the polymer to the dopants, resulting in white-emitting composites. The most intense and stable emission has been found when POC was doped with about 5 wt% concentration of Ir(ppy)3.

Full Text Available Bioinformatics is an integrated area of data mining, statistics and computational biology. Protein-Protein Interaction (PPI network is the most important biological process in living beings. In this network a protein module interacts with another module and so on, forming a large network of proteins. The same set of proteins which takes part in the organic courses of biological actions is detected through the Function Module Detection method. Clustering process when applied in PPI networks is made of proteins which are part of a larger communication network. As a result of this, we can define the limits for module detection as well as clarify the construction of a PPI network. For understating the bio-mechanism of various living beings, a detailed study of FMFinder detection by clustering process is called for.

Does the Sustainable PPI Investments Promote Financial Market’s Sustainable Development?

Directory of Open Access Journals (Sweden)

Tong Fu

2016-01-01

Full Text Available Since the late 1980s, most developing countries adopt a policy of attracting investments for Private Participation in Infrastructure (PPI projects. With a perspective of sustainability, this paper offers a first attempt to examine whether the sustainable PPI investments promote financial market development. First, we demonstrate how the PPI policy enlargers the size of financial markets and then fosters the liquidity of financial markets in the static and dynamic conditions. Using the data from 33 developing countries during 1997–2012, we discover the significant promotion effect of PPI investments on the development of financial markets in the dimensions of size and liquidity. Additionally, we confirm the significant mediator effect of financial market size for the positive relationship between PPI investments and financial market liquidity. Both the promotion effect and mediation effect are robust to different control variables and estimation techniques used.

Full Text Available Tin dioxide (SnO2 plays a dominant role in solid state gas sensors and exhibit sensitivity towards oxidizing and reducing gases by a variation of its electrical properties. The electrical conducting polymer-polypyrrole (PPy has high anisotropy of electrical conduction and used as a gas sensor. SnO2/PPy multilayer, pure SnO2, pure PPy sensors were prepared by screen-printing method on Al2O3 layer followed by glass substrate. The sensors were used for different concentration (ppm of CO2 gas investigation at room temperature (303 K. The sensitivity of SnO2/PPy multilayer sensor was found to be higher, compared with pure SnO2 and pure PPy sensors. The multilayer sensor exhibited improved stability. The response and recovery time of multilayer sensor were found to be ~2 min and ~10 min respectively.

Full Text Available Qufengtongluo (QFTL decoction is an effective treatment for diabetic nephropathy (DN. However, the underlying molecular mechanism is still unclear. In this study, we try to investigate whether QFTL decoction acts via inhibiting PI3K/Akt signaling pathway. Twenty-four GK rats were randomly divided into 3 groups: blank group, sham-operated group, and QFTL group. After model establishment, rats in QFTL group were given QFTL decoction by gavage, while the rest were given pure water. During the 8-week intervention, 24 hr urinal protein was measured every 2-3 weeks. After intervention, kidneys were removed for pathological smear, quantitative real-time PCR, and western blotting to detect expression levels of p-PI3K, p-Akt, PTEN, TGF-β, PI3K mRNA, Akt mRNA, PTEN mRNA, and TGF-β mRNA. QFTL group showed a slighter degree of renal fibrosis in Masson and PASM staining and a greater reduction of 24 hr urinal protein than blank group. Compared to blank group, expression levels of p-PI3K, p-Akt, PI3K mRNA, and Akt mRNA were lower in QFTL group, while expression levels of PTEN and PTEN mRNA were higher. Besides, TGF-β was downregulated by QFTL decoction. In conclusion, this study suggests that QFTL decoction might inhibit PI3K/Akt signaling pathway via activating PTEN and inhibiting TGF-β.

Revealing protein complexes are important for understanding principles of cellular organization and function. High-throughput experimental techniques have produced a large amount of protein interactions, which makes it possible to predict protein complexes from protein-protein interaction (PPI) networks. However, the small amount of known physical interactions may limit protein complex detection. The new PPI networks are constructed by integrating PPI datasets with the large and readily available PPI data from biomedical literature, and then the less reliable PPI between two proteins are filtered out based on semantic similarity and topological similarity of the two proteins. Finally, the supervised learning protein complex detection (SLPC), which can make full use of the information of available known complexes, is applied to detect protein complex on the new PPI networks. The experimental results of SLPC on two different categories yeast PPI networks demonstrate effectiveness of the approach: compared with the original PPI networks, the best average improvements of 4.76, 6.81 and 15.75 percentage units in the F-score, accuracy and maximum matching ratio (MMR) are achieved respectively; compared with the denoising PPI networks, the best average improvements of 3.91, 4.61 and 12.10 percentage units in the F-score, accuracy and MMR are achieved respectively; compared with ClusterONE, the start-of the-art complex detection method, on the denoising extended PPI networks, the average improvements of 26.02 and 22.40 percentage units in the F-score and MMR are achieved respectively. The experimental results show that the performances of SLPC have a large improvement through integration of new receivable PPI data from biomedical literature into original PPI networks and denoising PPI networks. In addition, our protein complexes detection method can achieve better performance than ClusterONE.

A Generalized Form of Context-Dependent Psychophysiological Interactions (gPPI): A Comparison to Standard Approaches

Functional MRI (fMRI) allows one to study task-related regional responses and task-dependent connectivity analysis using psychophysiological interaction (PPI) methods. The latter affords the additional opportunity to understand how brain regions interact in a task-dependent manner. The current implementation of PPI in Statistical Parametric Mapping (SPM8) is configured primarily to assess connectivity differences between two task conditions, when in practice fMRI tasks frequently employ more than two conditions. Here we evaluate how a generalized form of context-dependent PPI (gPPI; http://www.nitrc.org/projects/gppi), which is configured to automatically accommodate more than two task conditions in the same PPI model by spanning the entire experimental space, compares to the standard implementation in SPM8. These comparisons are made using both simulations and an empirical dataset. In the simulated dataset, we compare the interaction beta estimates to their expected values and model fit using the Akaike Information Criterion (AIC). We found that interaction beta estimates in gPPI were robust to different simulated data models, were not different from the expected beta value, and had better model fits than when using standard PPI (sPPI) methods. In the empirical dataset, we compare the model fit of the gPPI approach to sPPI. We found that the gPPI approach improved model fit compared to sPPI. There were several regions that became non-significant with gPPI. These regions all showed significantly better model fits with gPPI. Also, there were several regions where task-dependent connectivity was only detected using gPPI methods, also with improved model fit. Regions that were detected with all methods had more similar model fits. These results suggest that gPPI may have greater sensitivity and specificity than standard implementation in SPM. This notion is tempered slightly as there is no gold standard; however, data simulations with a known outcome support our

A full amplitude analysis of $\\Lambda_b^0 \\to J/\\psi p \\pi^-$ decays is performed with a data sample acquired with the LHCb detector from 7 and 8 TeV $pp$ collisions, corresponding to an integrated luminosity of 3 fb$^{-1}$. A significantly better description of the data is achieved when, in addition to the previously observed nucleon excitations $N\\to p\\pi^-$, either the $P_c(4380)^+$ and $P_c(4450)^+\\to J/\\psi p$ states, previously observed in $\\Lambda_b^0 \\to J/\\psi p K^-$ decays, or the $Z_c(4200)^-\\to J/\\psi \\pi^-$ state, previously reported in $B^0 \\to J/\\psi K^+ \\pi^-$ decays, or all three, are included in the amplitude models. The data support a model containing all three exotic states, with a significance of more than three standard deviations. Within uncertainties, the data are consistent with the $P_c(4380)^+$ and $P_c(4450)^+$ production rates expected from their previous observation taking account of Cabibbo suppression.

PPI finder: a mining tool for human protein-protein interactions.

Directory of Open Access Journals (Sweden)

Min He

Full Text Available BACKGROUND: The exponential increase of published biomedical literature prompts the use of text mining tools to manage the information overload automatically. One of the most common applications is to mine protein-protein interactions (PPIs from PubMed abstracts. Currently, most tools in mining PPIs from literature are using co-occurrence-based approaches or rule-based approaches. Hybrid methods (frame-based approaches by combining these two methods may have better performance in predicting PPIs. However, the predicted PPIs from these methods are rarely evaluated by known PPI databases and co-occurred terms in Gene Ontology (GO database. METHODOLOGY/PRINCIPAL FINDINGS: We here developed a web-based tool, PPI Finder, to mine human PPIs from PubMed abstracts based on their co-occurrences and interaction words, followed by evidences in human PPI databases and shared terms in GO database. Only 28% of the co-occurred pairs in PubMed abstracts appeared in any of the commonly used human PPI databases (HPRD, BioGRID and BIND. On the other hand, of the known PPIs in HPRD, 69% showed co-occurrences in the literature, and 65% shared GO terms. CONCLUSIONS: PPI Finder provides a useful tool for biologists to uncover potential novel PPIs. It is freely accessible at http://liweilab.genetics.ac.cn/tm/.

Medulloblastoma is comprised of at least four molecular subgroups with distinct clinical outcome (WHO classification 2016). SHH-TP53-mutated as well as MYC-amplified Non-WNT/Non-SHH medulloblastoma show the worst prognosis.Here we present evidence that single application of the multi-kinase inhibitor Vandetanib displays anti-neoplastic efficacy against cell lines derived from high-risk SHH-TP53-mutated and MYC-amplified Non-WNT/Non-SHH medulloblastoma. The narrow target spectrum of Vandetanib along with a favourable toxicity profile renders this drug ideal for multimodal treatment approaches. In this context our investigation documents that Vandetanib in combination with the clinically available PI3K inhibitor GDC-0941 leads to enhanced cytotoxicity against MYC-amplified and SHH-TP53-mutated medulloblastoma. In line with these findings we show for MYC-amplified medulloblastoma a profound reduction in activity of the oncogenes STAT3 and AKT. Furthermore, we document that Vandetanib and the standard chemotherapeutic Etoposide display additive anti-neoplastic efficacy in the investigated medulloblastoma cell lines that could be further enhanced by PI3K inhibition. Of note, the combination of Vandetanib, GDC-0941 and Etoposide results in MYC-amplified and SHH-TP53-mutated cell lines in complete loss of cell viability. Our findings therefore provide a rational to further evaluate Vandetanib in combination with PI3K inhibitors as well as standard chemotherapeutics in vivo for the treatment of most aggressive medulloblastoma variants.

Cathodic polarization antifouling deserves attention because of its environmentally friendly nature and good sustainability. It has been proven that cathodic voltages applied on metal substrates exhibit outstanding antifouling effects. However, most metals immersed in marine environment are protected by insulated anticorrosive coatings, restricting the cathodic polarization applied on metals. This study developed a conducting polypyrrole (PPy)/acrylic resin coating (σ = 0.18 Scm -1 ), which can be applied in cathodic polarization antifouling. The good stability and electro-activity of PPy in the negative polarity zone in alkalescent NaCl solution were verified by linear sweep voltammetry (LSV), chronoamperometry (CA), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), demonstrating the feasibility of PPy as cathodic polarization material. Furthermore, the antifouling effects of PPy/acrylicresin coating on 24-h old Escherichia coli bacteria (E. coli) which formed on PPy/acrylic resin-coated plastic plate were measured under different cathodic potentials and treatment time, characterized by fluorescent microscope. The results suggest that at cathodic potential around -0.5 V (vs. saturated calomel electrode (SCE)), there was little trace of attached bacteria on the substrate after 20 min of treatment. PPy/acrylicresin-coated substrates were also subjected to repeated cycles of biofilm formation and electrochemical removal, where high removal efficiencies were maintained throughout the total polarization process. Under these conditions, the generation of hydrogen peroxide is believed to be responsible for the antifouling effects because of causing oxidative damage to cells, suggesting the potential of the proposed technology for application on insulated surfaces in various industrial settings.

Tungsten oxide (WO{sub 3}) films are critical for smart windows because of their capacity of varying the throughput of visible light and solar energy. This study highlights the evolution of structural and morphological changes of electrodeposited WO{sub 3} thin films coated with polypyrrole (PPy) by using chemical bath deposition. The structural and surface properties of WO{sub 3} thin films were studied using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy. The electrochemical stability was inspected using repetitive cyclic voltammetry (CV) cycles for each sample in LiClO{sub 4}-PC electrolyte for prolonged periods. The results showed an improvement in the electrochemical stability after the CV study. - Graphical abstract: Mechanism: A schematic of the mechanism is proposed in above fig. The mechanism is based on three step process: (i) WO{sub 3} coated on ITO by electrodeposition followed by thermal treatment. It produces ordered nanoarrayed morphology. (ii) A second step involving deposition of PPy by chemical bath deposition on ITO. It possesses globular morphology. (iii) When PPy coated on WO{sub 3}, PPy applies shearing force on WO{sub 3} and produces disordered nanoarrayed morphology. - Highlights: • Nanoarrayed WO{sub 3}/PPy composite was synthesized. • Interplanar spacing enhances due to PPy coating. • PPy applies shearing force on WO{sub 3} produces disordered morphology. • Nanocomposite showed high stability in LiClO{sub 4}-PC.

Recently, we reported that Ilexgenin A exhibits anti-cancer activities and induces cell arrest. Here, we investigated the effect of Ilexgenin A on the inflammation, angiogenesis and tumor growth of hepatocellular carcinoma (HCC). Our current study revealed that Ilexgenin A significantly inhibited the inflammatory cytokines TNF-α and IL-6 levels and downregulated pro-angiogenic factor VEGF production and transcription in HepG2 cells. The underlying mechanism for Ilexgenin A effects appears to be through inhibiting STAT3 and PI3K pathways. Furthermore, we found that not only Ilexgenin A inhibited STAT3 and PI3K pathways in HepG2 cells but also blocked these signaling pathways in HUVECs. Most importantly, by employing two HCC xenografts models - HepG2 and H22, we showed that Ilexgenin A reduced tumor growth and exhibited synergy effect with Sorafenib. ELISA assay, histological analysis and immunohistochemistry examination revealed that the expression of VEGF and MVD was significantly decreased after the treatment with Ilexgenin A and the combination. Moreover, Ilexgenin A could enhance caspase-3/7 activity in vitro and transmission electron microscope indicated that the combination induced evident apoptosis of tumor cells and caused the structural changes of mitochondria in vivo. Although no apparent adverse effects occurred during the treatment period, Sorafenib monotherapy elicited hepatotoxicity for specific expression in the increased level of AST and the ratio of AST/ALT. However, the combination could remedy this adverse effect. In conclusion, the results described in the present study identifies Ilexgenin A as a promising therapeutic candidate that modulates inflammation, angiogenesis, and HCC growth. - Highlights: • Ilexgenin A exerts anti-inflammatory and anti-angiogenesis effects in hepatoma. • Ilexgenin A may exert these effects through inhibition of STAT3 and PI3K pathways. • Ilexgenin A exhibits synergistic effects with Sorafenib on hepatoma growth

2014-01-01

Polypyrrole (PPy) conducting polymers have shown a great potential for the fabrication of conjugated polymer-based actuating devices. Consequently, they have been a key point in developing many advanced emerging applications such as biomedical devices and biomimetic robotics. When designing an actuator, taking all of the related decision variables, their roles and relationships into consideration is of pivotal importance to determine the actuator’s final performance. Therefore, the central focus of this study is to develop an electrochemomechanical constrained multiobjective optimization model of a PPy/MWCNTs trilayer actuator. For this purpose, the objective functions are designed to capture the three main characteristics of these actuators, namely their tip vertical displacement, blocking force and response time. To obtain the optimum range of the designated decision variables within the feasible domain, a multiobjective optimization algorithm is applied while appropriate constraints are imposed. The optimum points form a Pareto surface on which they are consistently spread. The numerical results are presented; these results enable one to design an actuator with consideration to the desired output performances. For the experimental analysis, a multilayer bending-type actuator is fabricated, which is composed of a PVDF layer and two layers of PPy with an incorporated layer of multi-walled carbon nanotubes deposited on each side of the PVDF membrane. The numerical results are experimentally verified; in order to determine the performance of the fabricated actuator, its outputs are compared with a neat PPy actuator’s experimental and numerical counterparts.

Blocking protein-protein interactions (PPI) using small molecules or peptides modulates biochemical pathways and has therapeutic significance. PPI inhibition for designing drug-like molecules is a new area that has been explored extensively during the last decade. Considering the number of available PPI inhibitor databases and the limited number of 3D structures available for proteins, docking and scoring methods play a major role in designing PPI inhibitors as well as stabilizers. Docking methods are used in the design of PPI inhibitors at several stages of finding a lead compound, including modeling the protein complex, screening for hot spots on the protein-protein interaction interface and screening small molecules or peptides that bind to the PPI interface. There are three major challenges to the use of docking on the relatively flat surfaces of PPI. In this review we will provide some examples of the use of docking in PPI inhibitor design as well as its limitations. The combination of experimental and docking methods with improved scoring function has thus far resulted in few success stories of PPI inhibitors for therapeutic purposes. Docking algorithms used for PPI are in the early stages, however, and as more data are available docking will become a highly promising area in the design of PPI inhibitors or stabilizers.

A case of Graves` disease occurring in a patient with hemiagenesis is presented. The detection of the rare occurrence of a congential hemiagenesis is often made by either clinical symptoms of thyroid dysfunction or anatomical abnormalities such as nodular goiter. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning and ultrasonography of an absent lobe. Anti-thyroid antibody studies documented the presence of Graves` disease within the remaining lobe. (orig.)

Calibration of LHCb RICH detectors with \\Lambda \\to p\\pi decay using data

CERN Multimedia

Popovici, Bogdan

2008-01-01

The LHCb physics programme will focus on high precision studies of CP violation and rare phenomena in B hadron decays. The RICH detectors of LHCb will provide hadron identification over the wide momentum range 1 to 100 GeV/c, and are central to the physics goals of the experiment. An excellent understanding of the hadron identification performance of the RICH detectors is essential. To achieve this goal, calibration strategies have been devised that will enable the performance to be measured from the data themselves. The decay chain $\\Lambda \\to p \\pi$ can be cleanly selected, based on its kinematic signature, without the use of RICH information. These events can be used as an unbiased sample for calibrating the RICH particle identification performance of pions and protons. In this way, the calibration method using the high purity samples of $\\Lambda$'s will be described.

HomPPI: a class of sequence homology based protein-protein interface prediction methods

2011-06-01

Full Text Available Abstract Background Although homology-based methods are among the most widely used methods for predicting the structure and function of proteins, the question as to whether interface sequence conservation can be effectively exploited in predicting protein-protein interfaces has been a subject of debate. Results We studied more than 300,000 pair-wise alignments of protein sequences from structurally characterized protein complexes, including both obligate and transient complexes. We identified sequence similarity criteria required for accurate homology-based inference of interface residues in a query protein sequence. Based on these analyses, we developed HomPPI, a class of sequence homology-based methods for predicting protein-protein interface residues. We present two variants of HomPPI: (i NPS-HomPPI (Non partner-specific HomPPI, which can be used to predict interface residues of a query protein in the absence of knowledge of the interaction partner; and (ii PS-HomPPI (Partner-specific HomPPI, which can be used to predict the interface residues of a query protein with a specific target protein. Our experiments on a benchmark dataset of obligate homodimeric complexes show that NPS-HomPPI can reliably predict protein-protein interface residues in a given protein, with an average correlation coefficient (CC of 0.76, sensitivity of 0.83, and specificity of 0.78, when sequence homologs of the query protein can be reliably identified. NPS-HomPPI also reliably predicts the interface residues of intrinsically disordered proteins. Our experiments suggest that NPS-HomPPI is competitive with several state-of-the-art interface prediction servers including those that exploit the structure of the query proteins. The partner-specific classifier, PS-HomPPI can, on a large dataset of transient complexes, predict the interface residues of a query protein with a specific target, with a CC of 0.65, sensitivity of 0.69, and specificity of 0.70, when homologs of

PpiA, a surface PPIase of the cyclophilin family in Lactococcus lactis.

Directory of Open Access Journals (Sweden)

Nicolas Trémillon

Full Text Available BACKGROUND: Protein folding in the envelope is a crucial limiting step of protein export and secretion. In order to better understand this process in Lactococcus lactis, a lactic acid bacterium, genes encoding putative exported folding factors like Peptidyl Prolyl Isomerases (PPIases were searched for in lactococcal genomes. RESULTS: In L. lactis, a new putative membrane PPIase of the cyclophilin subfamily, PpiA, was identified and characterized. ppiA gene was found to be constitutively expressed under normal and stress (heat shock, H(2O(2 conditions. Under normal conditions, PpiA protein was synthesized and released from intact cells by an exogenously added protease, showing that it was exposed at the cell surface. No obvious phenotype could be associated to a ppiA mutant strain under several laboratory conditions including stress conditions, except a very low sensitivity to H(2O(2. Induction of a ppiA copy provided in trans had no effect i on the thermosensitivity of an mutant strain deficient for the lactococcal surface protease HtrA and ii on the secretion and stability on four exported proteins (a highly degraded hybrid protein and three heterologous secreted proteins in an otherwise wild-type strain background. However, a recombinant soluble form of PpiA that had been produced and secreted in L. lactis and purified from a culture supernatant displayed both PPIase and chaperone activities. CONCLUSIONS: Although L. lactis PpiA, a protein produced and exposed at the cell surface under normal conditions, displayed a very moderate role in vivo, it was found, as a recombinant soluble form, to be endowed with folding activities in vitro.

Full Text Available Studies suggest proton pump inhibitor (PPI use impacts body weight regulation, though the effect of PPIs on energy intake, energy extraction, and energy expenditure is unknown. We used data on 3073 eligible adults from the National Health and Nutrition Examination Survey (NHANES. Medication use, energy intake, diet composition, and physical activity were extracted from NHANES. Multivariate regression models included confounding variables. Daily energy intake was similar between PPI users and non-users (p = 0.41. Diet composition was similar between the two groups, except that PPI users consumed a slightly greater proportion of calories from fat (34.5% vs. 33.2%; p = 0.02. PPI users rated themselves as being as physically active as their age/gender-matched peers and reported similar frequencies of walking or biking. However, PPI users were less likely to have participated in muscle-strengthening activities (OR: 0.53; 95% CI: 0.30–0.95. PPI users reported similar sedentary behaviors to non-users. Male PPI users had an increase in weight (of 1.52 ± 0.59 kg; p = 0.021 over the previous year compared to non-users, while female PPI users had a non-significant increase in weight. The potential mechanisms for PPI-associated weight gain are unclear as we did not find evidence for significant differences in energy intake or markers of energy expenditure.

Full Text Available Die medikamentöse Behandlung von Herzrhythmusstörungen ist unbefriedigend, da bei guter Wirksamkeit durch die Proarrhythmie eine Verbesserung der Prognose gefährdet und nicht gesichert ist. Man kann davon ausgehen, daß Magnesiumsalze keine arrhythmogene Effekte aufweisen. Bei Patienten mit einer Herzinsuffizienz besteht häufig ein Mg-Mangel, der durch gastrointestinale Störungen, neurohormonale Regulationen, aber auch durch die Therapie (Diuretika,Digitalisbedingt ist. An Patienten mit einer Herzinsuffizienz müßte sich demnach zeigen lassen, ob die Mg-Substitution einen antiarrhythmischen Effekt aufweist. In fünf placebokontrollierten Studien konnte gezeigt werden, daß sich teil weise signifikant und mit ausreichen der Aussagekraft (PowerArrhythmien bei Patienten mit Herzinsuffizienz durch orale und parenterale Gabe von Mg-Salzen reduzieren lassen. Trotz Einschränkungen wie z.B. inadäquates Design, fehlende Vermeidung von Bias, ungenügende Vergleichbarkeit der Behandlungsgruppen, inadäquate Auswertung und ungenügende Berücksichtigung der Spontanvariation läßt sich aufgrund der Ergebnisse der Studien die Hypothese aufstellen, daß Magnesiumsalze bei Patienten mit Herzinsuffizienz Herzrhythmusstörungen günstig beeinflussen können. Prospektive, randomisierte,verblindete und kontrollierte konfirmatorische Studien mit ausreichenden Fallzahlen sind jedoch notwendig, um diese Hypothese zu bestätigen.

The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0- spin-parity states is also observed, whereas contributions of 2- states and of a state with spin-parity 2+ and zero helicity are found to be negligible.

2003-02-28

The photoelectrochemical properties of polypyrrole (PPy) film in aqueous solutions in the potential region of -0.7 to 0.5 V (versus Ag/AgCl) were investigated by using photocurrent, photothermal and photothermal current methods under the irradiation of laser beams with wavelength of 532 and 632.8 nm, respectively. It was found that the photocurrent at more negative potential was caused by the p-type semiconductor properties, while the photocurrent at more positive potential was caused by the local temperature rather than the semiconductor properties of the films. The effect of the film thickness on the photocurrent of PPy films was studied in detail.

In mobile equipment, in demand is a high precision liquid crystal display (LCD) having the power of expression equivalent to printed materials like magazines because of the necessity of displaying a large amount of information on a easily potable small screen. In addition, with the spread and high-quality image of digital still cameras, it is strongly desired to display photographed digital image data in high quality. Toshiba Corp., by low temperature polysilicone (p-Si) technology, commercialized the liquid crystal display series of 200 ppi (pixels per inch) precision dealing with the rise of the high-precision high-image quality LCD market. The super high precision of 200 ppi enables the display of smooth beautiful animation comparable to printed sheets of magazines and photographs. The display series are suitable for the display of various information services such as electronic books and electronic photo-viewers including internet. The screen sizes lined up are No. 4 type VGA (640x480 pixels) of a small pocket notebook size and No. 6.3 type XGA (1,024x768 pixels) of a paperback size, with a larger screen to be furthered.

We analyse tau to pi pi pi nu /sub tau / decays within the framework of the resonance effective theory of QCD. We have worked out the relevant Lagrangian that describes the axial-vector current hadronization contributing to these processes, and the new coupling constants that arise have been constrained by imposing the asymptotic behaviour of the corresponding spectral function within QCD. Hence we compare the theoretical framework with the experimental data, obtaining a good quality fit from the ALEPH spectral function and branching ratio. We also get values for the mass and on-shell width of the a/sub 1/(1260) resonance, and provide the tau to pi pi pi nu /sub tau / structure functions that have been measured by OPAL and CLEO-II finding an excellent agreement.

To estimate the impact of adherence with proton pump inhibitor (PPI) therapy on the incidence of nonsteroidal anti-inflammatory drug (NSAID)-induced gastropathy (NSAID gastropathy) in patients with rheumatoid arthritis (RA). PPI pharmacotherapy adherence was estimated using the Medication Adherence Questionnaire (MAQ) in 92 patients with RA, including 32 patients did not take a PPI and 60 used a PPI. The groups were matched for age, disease duration, and used NSAIDs. All those asked underwent video esophagogastroduodenoscopy. According to the data of MAQ survey, low, moderate, and high adherence subgroups could be identified among the patients treated with a PPI. NSAID gastropathy was detected in 43.8% of the patients taking no PPI, in 50% of those with low PPI treatment adherence, in 12.5% with moderate adherence, and in 4.5% with high adherence. In the patients with low adherence to PPI therapy, NSAID gastropathy was recorded 11 times more frequently than in those with high adherence (c2 = 7.77; p = 0.005). This condition occurred in 28.6% of the patients taking NSAID without preventively using a PPI in the absence of risk factors for NSAID gastropathy. Only 36.7% patients who had been recommended to use a PPI for the prevention of NSAID gastropathy strictly observed their doctor's directions. Low PPI pharmacotherapy adherence may serve as an additional risk factor for NSAID gastropathy in patients in whom preventive antisecretory therapy used in combination with NSAID is indicated.

Conductive polymer composites (CPCs) containing nanoscale conductive fillers have been widely studied for their potential use in various applications. In this paper, polypyrrole (PPy)/polydopamine (PDA)/silver nanowire (AgNW) composites with high electromagnetic interference (EMI) shielding performance, good adhesion ability and light weight are successfully fabricated via a simple in situ polymerization method followed by a mixture process. Benefiting from the intrinsic adhesion properties of PDA, the adhesion ability and mechanical properties of the PPy/PDA/AgNW composites are significantly improved. The incorporation of AgNWs endows the functionalized PPy with tunable electrical conductivity and enhanced EMI shielding effectiveness (SE). By adjusting the AgNW loading degree in the PPy/PDA/AgNW composites from 0 to 50 wt%, the electrical conductivity of the composites greatly increases from 0.01 to 1206.72 S cm -1 , and the EMI SE of the composites changes from 6.5 to 48.4 dB accordingly (8.0-12.0 GHz, X-band). Moreover, due to the extremely low density of PPy, the PPy/PDA/AgNW (20 wt%) composites show a superior light weight of 0.28 g cm -3 . In general, it can be concluded that the PPy/PDA/AgNW composites with tunable electrical conductivity, good adhesion properties and light weight can be used as excellent EMI shielding materials.

Quantum-correlated $\\psi(3770) \\to D\\bar{D}$ decays collected by the CLEO-c experiment are used to perform a first measurement of $F_+^{4\\pi}$, the fractional $CP$-even content of the self-conjugate decay $D \\to \\pi^+\\pi^-\\pi^+\\pi^-$, obtaining a value of $0.737 \\pm 0.028$. An important input to the measurement comes from the use of $D \\to K^0_{\\rm S}\\pi^+\\pi^-$ and $D \\to K^0_{\\rm L}\\pi^+\\pi^-$ decays to tag the signal mode. This same technique is applied to the channels $D \\to\\pi^+\\pi^-\\pi^0$ and $D \\to K^+K^-\\pi^0$, yielding $F_+^{\\pi\\pi\\pi^0} = 1.014 \\pm 0.045 \\pm 0.022$ and $F_+^{KK\\pi^0} = 0.734 \\pm 0.106 \\pm 0.054$, where the first uncertainty is statistical and the second systematic. These measurements are consistent with those of an earlier analysis, based on $CP$-eigenstate tags, and can be combined to give values of $F_+^{\\pi\\pi\\pi^0} = 0.973 \\pm 0.017$ and $F_+^{KK\\pi^0} = 0.732 \\pm 0.055$. The results will enable the three modes to be included in a model-independent manner in measurements of the ...

The decays B+-> J/psi 3 pi(+)2 pi(-) and B+ -> psi(2S)pi(+)pi(+)pi(-) are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb(-1), collected by the LHCb experiment in proton- proton collisions at the centre-of-mass energies of 7 and 8 TeV. The branching fractions relative to that of B+ -> psi(2S)K+ are measured to be B(B+-> J/psi 3 pi(+)2 pi(-))/B(B+ -> psi (2S)K+) = (1.88 +/- 0.17 +/- 0.09)x10(-2).

Using 355 pb;{-1} of data collected by the CDF II detector in pp[over ] collisions at sqrt[s]=1.96 TeV at the Fermilab Tevatron, we study the fully reconstructed hadronic decays B_{(s)};{0}-->D_{(s)};{-}pi;{+} and B_{(s)};{0}-->D_{(s)};{-}pi;{+}pi;{+}pi;{-}. We present the first measurement of the ratio of branching fractions B(B_{s};{0}-->D_{s};{-}pi;{+}pi;{+}pi;{-})/B(B;{0}-->D;{-}pi;{+}pi;{+}pi;{-})=1.05+/-0.10(stat)+/-0.22(syst). We also update our measurement of B(B_{s};{0}-->D_{s};{-}pi;{+})/B(B;{0}-->D;{-}pi;{+}) to 1.13+/-0.08(stat)+/-0.23(syst), improving the statistical uncertainty by more than a factor of 2. We find B(B_{s};{0}-->D_{s};{-}pi;{+})=[3.8+/-0.3(stat)+/-1.3(syst)]x10;{-3} and B(B_{s};{0}-->D_{s};{-}pi;{+}pi;{+}pi;{-})=[8.4+/-0.8(stat)+/-3.2(syst)]x10;{-3}.

1999-01-01

Crystal Barrel data on pbarp -> pi sup 0 pi sup 0 are presented. Shapes of angular distributions are similar to data of Dulude et al, but show some systematic disagreements. Absolute normalisations disagree seriously. An amplitude analysis finds two alternative solutions. Both contain a J sup P sup C 2 sup + sup + resonance with M = 2020 +- 40 MeV and GAMMA = 235 +- 70 MeV, tentatively identified as the qbarq sup 3 F sub 2 state. Both solutions also require f sub 4 (2050) and f sub 4 (2300).

Solar Radiation Measurement Using Raspberry Pi and Its Modelling Using Artificial Neural Networks

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available The advent of solar energy as the best alternative to traditional energy sources has led to an extensive study on the measurement and prediction of solar radiation. Devices such as pyranometer, pyrrheliometer, global UV radiometer are used for the measurement of solar radiation. The solar radiation measuring instruments available at Innovation Center, MIT Manipal were integrated with a Raspberry Pi to allow remote access to the data through the university Local Area Network. The connections of the data loggers and the Raspberry Pi were enclosed in a plastic box to prevent damage from the rainfall and humidity in Manipal. The solar radiation data was used to validate an Artificial Neural Network model which was developed using various meterological data from 2011-2015.

Electrochemical Behaviour of a PPy(DBS)/Polyacrylonitrile (PAN):LITF:EC:PC/ Li Cell

Vidanapathirana, K.; Careem, M.A.; Skaarup, Steen

2006-01-01

The electrochemical behaviour of Li rechargeable cells with Polypyrrole (PPy) as the cathode material was investigated using cyclic voltammetry. The PPy used was doped with the large surfactant anion dodecyl benzenesulphonate (DBS-). The cells were constructed with PAN:LiTF:EC:PC gel electrolyte...... with Li as anode. The results indicate that during the first reduction, cations are inserted into the PPy film forming LiDBS neutral salt. During the next oxidation/reduction cycles, the mechanism then switches to anion movement. Cyclic voltammetry studies also verified that complete electrochemical...

We report a study of the suppressed $B^{-}\\to DK^-\\pi^+\\pi^-$ and favored $B^-\\to D\\pi^-\\pi^+\\pi^-$ decays, where the neutral $D$ meson is detected through its decays to the $K^{\\mp}\\pi^{\\pm}$ and $CP$-even $K^+K^-$ and $\\pi^+\\pi^-$ final states. The measurement is carried out using a proton-proton collision data sample collected by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{-1}$. We observe the first significant signals in the $CP$-even final states of the $D$ meson for both the suppressed $B^{-}\\to DK^-\\pi^+\\pi^-$ and favored $B^-\\to D\\pi^-\\pi^+\\pi^-$ modes, as well as in the doubly Cabibbo-suppressed $D\\to K^+\\pi^-$ final state of the $B^-\\to D\\pi^-\\pi^+\\pi^-$ decay. Evidence for the ADS suppressed decay $B^{-}\\to DK^-\\pi^+\\pi^-$, with $D\\to K^+\\pi^-$, is also presented. From the observed yields in the $B^{-}\\to DK^-\\pi^+\\pi^-$, $B^-\\to D\\pi^-\\pi^+\\pi^-$ and their charge conjugate decay modes, we measure the value of the weak phase to be $\\gamma=(74^{+20}_{-18})^{\\rm o}$.

Highlights: {yields} Nuclear translocation of GST{pi} is abrogated by the deletion of the last 16 amino acid residues in the carboxy-terminal region, indicating that residues 195-208 of GST{pi} are required for nuclear translocation. {yields} The lack of a contiguous stretch of positively charged amino acid residues within the carboxy-terminal region of GST{pi}, suggests that the nuclear translocation of GST{pi} is mediated by a non-classical nuclear localization signal. {yields} An in vitro transport assay shows that the nuclear translocation of GST{pi} is dependent on cytosolic factors and ATP. -- Abstract: Glutathione S-transferase {pi} (GST{pi}), a member of the GST family of multifunctional enzymes, is highly expressed in human placenta and involved in the protection of cellular components against electrophilic compounds or oxidative stress. We have recently found that GST{pi} is expressed in the cytoplasm, mitochondria, and nucleus in some cancer cells, and that the nuclear expression of GST{pi} appears to correlate with resistance to anti-cancer drugs. Although the mitochondrial targeting signal of GST{pi} was previously identified in the amino-terminal region, the mechanism of nuclear translocation remains completely unknown. In this study, we find that the region of GST{pi}195-208 is critical for nuclear translocation, which is mediated by a novel and non-classical nuclear localization signal. In addition, using an in vitro transport assay, we demonstrate that the nuclear translocation of GST{pi} depends on the cytosolic extract and ATP. Although further experiments are needed to understand in depth the precise mechanism of nuclear translocation of GST{pi}, our results may help to establish more efficient anti-cancer therapy, especially with respect to resistance to anti-cancer drugs.

AIM: To determine non-steroidal anti-inflammatory drug (NSAID) prescribing practices in a tertiary referral hospital. METHODS: A single time-point audit of drug kardexes and clinical notes of n = 388 patients on 2 July 2008 was carried out assessing demographics, gastrointestinal and coronary heart disease risk factors, renal function and co-prescribed medications. RESULTS: Fifty-seven of 388 (14.7%) hospital patients were on NSAIDs. Forty-nine were prescribed NSAID after admission. Nineteen (32.2%) were on regular NSAID (11\\/19 on PPI) and 38 patients were on PRN NSAID (12\\/38 on PPI). Seventeen of 49 patients were on other medications associated with gastrointestinal bleeding (10\\/17 were on PPI). Nineteen patients (33.3%) were >60 years. Eight patients had three or four risk factors for gastrointestinal bleeding; six were on PPI. Thirteen patients had two risks; 7 were on PPI. Six of 19 patients with one risk factor were on PPI. 40.3% had stage 2\\/3 chronic kidney disease. 35.1% had ischaemic heart disease. CONCLUSIONS: NSAIDs and PPIs are often prescribed inappropriately.

We study the process e+e- -> pi+pi-pi+pi-gamma, with a photon emitted from the initial-state electron or positron, using 454.3 fb^-1 of data collected with the BABAR detector at SLAC, corresponding to approximately 260,000 signal events. We use these data to extract the non-radiative sigma(e+e- ->pi+pi-pi+pi-) cross section in the energy range from 0.6 to 4.5 Gev. The total uncertainty of the cross section measurement in the peak region is less than 3%, higher in precision than the corresponding results obtained from energy scan data.

A search for $CP$ violation in the phase-space structures of $D^{0}$ and $\\bar{D^{0}}$ decays to the final states $K^{-}K^{+}\\pi^{-}\\pi^{+}$ and $\\pi^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ is presented. The search is carried out with a data set corresponding to an integrated luminosity of 1.0 fb$^{−1}$ collected in 2011 by the LHCb experiment in $pp$ collisions at a centre-of-mass energy of 7 TeV. For the $K^{-}K^{+}\\pi^{-}\\pi^{+}$ final state, the four-body phase space is divided into 32 bins, each bin with approximately 1800 decays. The $p$-value under the hypothesis of no $CP$ violation is 9.1 %, and in no bin is a $CP$ asymmetry greater than 6.5 % observed. The phase space of the $\\pi^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ final state is partitioned into 128 bins, each bin with approximately 2500 decays. The p-value under the hypothesis of no $CP$ violation is 41 %, and in no bin is a $CP$ asymmetry greater than 5.5 % observed. All results are consistent with the hypothesis of no $CP$ violation at the current sensitivity.

The reaction anti-proton + proton -> anti-\\Lambda + \\Lambda -> anti-proton + \\pi^+ + proton + \\pi^- has been measured with high statistics at anti-proton beam momentum of 1.637 GeV/c. The use of a transversely-polarized frozen-spin target combined with the self-analyzing property of \\Lambda/anti-\\Lambda decay allows access to unprecedented information on the spin structure of the interaction. The most general spin-scattering matrix can be written in terms of eleven real parameters for each bin of scattering angle, each of these parameters is determined with reasonable precision. From these results all conceivable spin-correlations are determined with inherent self-consistency. Good agreement is found with the few previously existing measurements of spin observables in anti-proton + proton -> anti-\\Lambda + \\Lambda near this energy. Existing theoretical models do not give good predictions for those spin-observables that had not been previously measured.

Purpose: To assess the feasibility of magnetic resonance imaging (MRI)-planned partial salvage permanent prostate implant (psPPI) among patients with biopsy-proven local recurrence after initial PPI without evidence of distant disease. Methods and Materials: From 2003-2009, 15 patients underwent MRI/magnetic resonance spectroscopy (MRS) planning for salvage brachytherapy (psPPI, I-125 [n=14; 144 Gy]; Pd-103 [n=1; 125 Gy]) without hormone therapy. Full dose was prescribed to areas of recurrence and underdosage, without entire prostate implantation. Limiting urethral and rectal toxicity was prioritized. Follow-up was from salvage date to prostate-specific antigen (PSA) concentration failure (Phoenix criteria = nadir + 2.0; ASTRO = 3 consecutive rises), recurrence, distant metastases, or last follow-up PSA level. Progression-free survival (PFS) was defined as no PSA failure or biopsy-proven recurrence without all-cause mortality. Toxicity was scored using Common Terminology Criteria for Adverse Events version 4.0. Results: At salvage, median age was 68 years, and PSA concentration was 3.5 ng/mL (range, 0.9-5.6 ng/mL). Abnormal MRI/MRS findings were evident in 40% of patients. Biopsy-proven recurrences consisted of a single focus (80%) or 2 foci (20%). At recurrence, Gleason score was 6 (67%) or ≥7 (27%). Median interval between initial and salvage implantation was 69 months (range, 28-132 months). psPPI planning characteristics limited doses to the rectum (mean V100 = 0.5% [0.07 cc]) and urethra (V100 = 12% [0.3 cc]). At median follow-up (23.3 months; range, 8-88 months), treatment failure (n=2) resulted only in localized recurrence; both patients underwent second psPPI with follow-up PSA tests at 12 and 26 months, resulting in 0.6 and 0.7 ng/mL, respectively. American Society for Radiation Oncology PFS rates at 1, 2, and 3 years were 86.7%, 78.4%, and 62.7%, respectively, with 5 patients for whom treatment failed (n=3 with negative transrectal ultrasound

Funders of research are increasingly requiring researchers to involve patients and the public in their research. Patient and public involvement (PPI) in research can potentially help researchers make sure that the design of their research is relevant, that it is participant friendly and ethically sound. Using and sharing PPI resources can benefit those involved in undertaking PPI, but existing PPI resources are not used consistently and this can lead to duplication of effort. This paper describes how we are developing a toolkit to support clinical trials teams in a clinical trials unit. The toolkit will provide a key 'off the shelf' resource to support trial teams with limited resources, in undertaking PPI. Key activities in further developing and maintaining the toolkit are to: ● listen to the views and experience of both research teams and patient and public contributors who use the tools; ● modify the tools based on our experience of using them; ● identify the need for future tools; ● update the toolkit based on any newly identified resources that come to light; ● raise awareness of the toolkit and ● work in collaboration with others to either develop or test out PPI resources in order to reduce duplication of work in PPI. Background Patient and public involvement (PPI) in research is increasingly a funder requirement due to the potential benefits in the design of relevant, participant friendly, ethically sound research. The use and sharing of resources can benefit PPI, but available resources are not consistently used leading to duplication of effort. This paper describes a developing toolkit to support clinical trials teams to undertake effective and meaningful PPI. Methods The first phase in developing the toolkit was to describe which PPI activities should be considered in the pathway of a clinical trial and at what stage these activities should take place. This pathway was informed through review of the type and timing of PPI activities within

Communication: Conjugated polymers such as polypyrrole (PPy) have potential use as artificial muscles or in microsystems such as valves for micro-fluid handling. One of the most important parameters in such uses is the magnitude of volume change during associated redox processes; however, until now...... estimates have varied greatly. Atomic force microscopy is reported here as allowing direct measurement of the in situ thickness change during oxidation and reduction of thin films of PPy doped with dodecylbenzenesulfonate....

A new technique of asymmetry measurement involving simultaneous $K^+$ and $K^-$ beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to be $A^c_g=(-1.5\\pm2.1)\\times10^{-4}$ with $3.11\\times 10^9$ $K^{\\pm}\\to\\pi^\\pm\\pi^+\\pi^-$ decays, and $A^n_g=(1.8\\pm1.8)\\times10^{-4}$ with $9.13\\times 10^7$ $K^{\\pm}\\to\\pi^\\pm\\pi^0\\pi^0$ decays. The precision of the results is limited mainly by the size of the data sample.

Extraction of the $\\pi^+\\pi^-$ Subsystem in Diffractively Produced $\\pi^-\\pi^+\\pi^-$ at COMPASS

2017-01-01

The COMPASS experiment at CERN has collected a large data sample of 50 million diffractively produced $\\pi^-\\pi^+\\pi^-$ events using a $190\\,$GeV$/c$ negatively charged hadron beam. The partial-wave analysis (PWA) of these high-precision data reveals previously unseen details. The PWA, which is currently limited by systematic uncertainties, is based on an isobar model, where multi-particle decays are described as subsequent two-body decays and where a prior-knowledge parametrization for the intermediate two-pion resonances has to be assumed -- usually a Breit-Wigner amplitude -- thus increasing systematic uncertainties, due to the concrete choice of the parametrization. We present a novel method, which allows to extract isobar amplitudes directly from the data in a less biased way. The focus lies on the scalar $\\pi^+\\pi^-$ subsystem, where a previous analysis found a signal for a new axial-vector state $a_1(1420)$ decaying into $f_0(980)\\pi$.

Polypyrrole-poly(3,4-ethylenedioxythiophene)-Ag (PPy-PEDOT-Ag) nanocomposite films for label-free electrochemical DNA sensing.

The electrochemical DNA hybridization sensing of bipolymer polypyrrole and poly(3,4-ethylenedioxythiophene) (PPy-PEDOT) nanotubes functionalized with Ag nanoparticles has been investigated. The bipolymer nanotubes are prepared by simple chemical route and silver nanoparticles (Ag) further deposited over the PPy-PEDOT nanotubes to form PPy-PEDOT-Ag nanocomposite films. DNA labeled at 5'end using 6-mercapto-1-hexhane (HS-ssDNA) is immobilized on the PPy-PEDOT-Ag surface to form PPy-PEDOT-Ag-S-ssDNA and hybridization sensing is done in phosphate buffer. The presence of Ag nanoparticles (~28±5nm) well dispersed in the polymer composite with high surface area, high electrical conductivity and catalytic activity provides desirable microenvironment for the immobilization of probe DNA with controlled orientation leading to increased hybridization efficiency with target DNA. The morphological and structural characterizations by a scanning electron microscope (SEM) and X-ray diffraction (XRD) confirm the nanotube structure of composite polymer while Raman measurements indicate the efficient interactions between the PPy, PEDOT, Ag and HS-ssDNA. The sensor effectively discriminates different target DNA sequences with PPy-PEDOT-Ag-S-ssDNA substrate. The observed dynamic detection range is found between 1×10(-11)M and 1×10(-14)M with the lowest detection limit (3 σ/b) of 5.4×10(-15)M. This observed value is of higher sensitivity than that for MWCNT-Ag, PANi-Au, MWCNT-PPy-Au and PPy-PANi-Au composites reported previously. Copyright © 2013 Elsevier B.V. All rights reserved.

The COMPASS collaboration at CERN has investigated the $\\pi^-\\gamma \\to \\pi^-\\pi^-\\pi^+$ reaction at center-of-momentum energy below five pion masses, $\\sqrt{s} \\lt 5m_\\pi$ , embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasi-real photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, $t' \\lt 0.001 GeV^2/c^2$. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3pi-invariant mass $m_{3\\pi} = \\sqrt{s}$ were extracted. The absolute cross section was determined in seven bins of $\\sqrt{s}$ with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

Zeros of the pi /sup +/ pi /sup -/ to pi /sup +/ pi /sup -/ amplitude (from data on pp to pi /sup -/ pi /sup +/)

Recent data on the reaction pp to pi /sup -/ pi /sup +/ show four conspicuous dips in the angular distribution at fixed values of nu =t- u. The conjecture is made that the channel pi /sup -/ pi /sup +/ to pi /sup -/ pi /sup +/ has zeros at the same nu values. Using data of the CERN-Munich group, one can follow the zeros through the whole Mandelstam plane. The zeros pass through the intersections of s and t channel poles, as the Veneziano model predicts; however, away from these intersections, they propagate in a fashion systematically quite different from Veneziano's ansatz.

An analysis of $B^{\\pm}\\to DK^{\\pm}$ and $B^{\\pm}\\to D\\pi^{\\pm}$ decays is presented where the $D$ meson is reconstructed in the four-body final state $K^{\\pm}\\pi^{\\mp} \\pi^+ \\pi^-$. Using LHCb data corresponding to an integrated luminosity of $1.0{\\rm \\,fb}^{-1}$, first observations are made of the suppressed ADS modes $B^{\\pm}\\to [\\pi^{\\pm} K^{\\mp}\\pi^+\\pi^-]_D K^{\\pm}$ and $B^{\\pm}\\to [\\pi^{\\pm} K^{\\mp} \\pi^+\\pi^- ]_D\\pi^{\\pm}$ with a significance of $5.1\\sigma$ and greater than $10\\sigma$, respectively. Measurements of $CP$ asymmetries and $CP$-conserving ratios of partial widths from this family of decays are also performed. The magnitude of the ratio between the suppressed and favoured $B^{\\pm}\\to DK^{\\pm}$ amplitudes is determined to be $r^K_B = 0.097 \\pm{0.011}$.

A simple chemical oxidative polymerization of pyrrole (Py) directly onto the surface of LiFePO 4 particles was applied to the synthesis of polypyrrole-LiFePO 4 (PPy-LiFePO 4 ) powder. The LiFePO 4 sample without carbon coating was synthesized by a solvothermal method. The polyethylene glycol (PEG) was used as additive during Py polymerization for increasing the PPy-LiFePO 4 conductivity. Properties of resulting LiFePO 4 , PPy-LiFePO 4 and PPy/PEG-LiFePO 4 samples were characterized by XRD, SEM, TGA and galvanostatic charge-discharge measurements. These methods confirmed the presence of polypyrrole on LiFePO 4 particles and its homogeneous distribution in the resulting powder material. The PPy/PEG-LiFePO 4 composites show higher discharge capacity than pure LiFePO 4 , as PPy/PEG network improves the electron conductivity. It presents specific discharge capacity of 153 mAh/g at C/5 rate.

We report the results from a study of the full sample of $~6.031 x 10^{7} K^{\\pm} \\to \\pi^{\\pm} \\pi^{0} \\pi^{0}$ decays recorded by the NA48/2 experiment at the CERN SPS. As first observed in this experiment, the $\\pi^{0} \\pi^{0}$ invariant mass (M_00) distribution shows a cusp-like anomaly in the region around $M_{00} = 2m_{+}$, where m_{+} is the charged pion mass. This anomaly has been interpreted as an effect due mainly to the final state charge exchange scattering process $\\pi^{+}\\pi^{-} \\to \\pi^{0} \\pi^{0}$ in $K^{\\pm} \\to \\pi^{\\pm} \\pi^{+} \\pi^{-}$ decay. Fits to the M_{00} distribution using two different theoretical models provide the presently most precise determination of $a_{0}-a_{2}$, the difference between the pi pi S-wave scattering lengths in the isospin I = 0 and I = 2 states. Higher-order pi pi rescattering terms, included in the two models, allow also an independent, though less precise, determination of a_2.

Wiki-pi: a web-server of annotated human protein-protein interactions to aid in discovery of protein function.

Directory of Open Access Journals (Sweden)

Naoki Orii

Full Text Available Protein-protein interactions (PPIs are the basis of biological functions. Knowledge of the interactions of a protein can help understand its molecular function and its association with different biological processes and pathways. Several publicly available databases provide comprehensive information about individual proteins, such as their sequence, structure, and function. There also exist databases that are built exclusively to provide PPIs by curating them from published literature. The information provided in these web resources is protein-centric, and not PPI-centric. The PPIs are typically provided as lists of interactions of a given gene with links to interacting partners; they do not present a comprehensive view of the nature of both the proteins involved in the interactions. A web database that allows search and retrieval based on biomedical characteristics of PPIs is lacking, and is needed. We present Wiki-Pi (read Wiki-π, a web-based interface to a database of human PPIs, which allows users to retrieve interactions by their biomedical attributes such as their association to diseases, pathways, drugs and biological functions. Each retrieved PPI is shown with annotations of both of the participant proteins side-by-side, creating a basis to hypothesize the biological function facilitated by the interaction. Conceptually, it is a search engine for PPIs analogous to PubMed for scientific literature. Its usefulness in generating novel scientific hypotheses is demonstrated through the study of IGSF21, a little-known gene that was recently identified to be associated with diabetic retinopathy. Using Wiki-Pi, we infer that its association to diabetic retinopathy may be mediated through its interactions with the genes HSPB1, KRAS, TMSB4X and DGKD, and that it may be involved in cellular response to external stimuli, cytoskeletal organization and regulation of molecular activity. The website also provides a wiki-like capability allowing users

The pi pi phase-shifts have been determined by a Chew-Low extrapolation in the pi pi mass region from 500 to 1500 MeV using data of a spark chamber experiment on pi /sup -/p to pi /sup -/ pi /sup +/n at 17.2 GeV/c, which yielded 318000 events. The authors find an I=0 s- wave phase shift which increases slowly, passing through 90 degrees near 900 MeV, and then rises very rapidly. The old 'up' solution is eliminated on the basis of fits in the mass region from 900-1000 MeV. (13 refs).

Full Text Available Metastasis of cancer is the cause of the majority of cancer deaths. Active compound flaccidoxide-13-acetate, isolated from the soft coral Cladiella kashmani, has been found to exhibit anti-tumor activity. In this study, Boyden chamber analysis, Western blotting and gelatin zymography assays indicated that flaccidoxide-13-acetate exerted inhibitory effects on the migration and invasion of RT4 and T24 human bladder cancer cells. The results demonstrated that flaccidoxide-13-acetate, in a concentration-dependent manner, reduced the levels of matrix metalloproteinase-2 (MMP-2, MMP-9, urokinase-type plasminogen activator receptor (uPAR, focal adhesion kinase (FAK, phosphatidylinositide-3 kinases (PI3K, p-PI3K, AKT, p-AKT, mammalian target of rapamycin (mTOR, p-mTOR, Ras homolog gene family, member A (Rho A, Ras, mitogen-activated protein kinase kinase 7 (MKK7 and mitogen-activated protein kinase kinase kinase 3 (MEKK3, and increased the expressions of tissue inhibitor of metalloproteinase-1 (TIMP-1 and TIMP-2 in RT4 and T24 cells. This study revealed that flaccidoxide-13-acetate suppressed cell migration and invasion by reducing the expressions of MMP-2 and MMP-9, regulated by the FAK/PI3K/AKT/mTOR pathway. In conclusion, our study was the first to demonstrate that flaccidoxide-13-acetate could be a potent medical agent for use in controlling the migration and invasion of bladder cancer.

Melanoma is an aggressive form of human cancer with limited treatment options currently available. The present study was aimed to evaluate the anticancer activity of kaempferol (KAM) against the human malignant melanoma A375 cell line along with evaluation of its effects on apoptosis, cell cycle, cell migration and m-TOR/PI3K/AKT pathway. Effects on cell viability were assessed by MTT assay while clonogenic assay measured the effects of KAM on colony formation. Annexin V assay evaluated the apoptotic effects of KAM in these cells using flow cytometry. Effects on cell cycle were determined by using flow cytometry with propidium iodide (PI) as probe. The effects of KAM on m-TOR/ PI3K/AKT signalling pathway were evaluated by western blot assay. MTT assay indicated that KAM exhibits a significant anticancer activity against A375 cells with an IC50 of 20 μM. These antiproliferative effects of KAM were also supported by the colony formation assay wherein KAM reduced the colony formation in a dose-dependent manner. The anticancer effect of KAM was found to be due to the initiation of apoptosis in human malignant melanoma A375 cells. Additionally, KAM also exhibited the capacity to trigger G2/M cell cycle arrest and to inhibit the cell migratory potential of A375 cells. KAM caused significant downregulation of m-TOR, phosphorylated (p) m-TOR, PI3K, p-PI3K and Akt protein levels in A375 malignantmelanoma cells. KAM exerts potent anticancer effects via induction of apoptosis, G2/M cell cycle arrest, cell migration inhibition and downregulation of m-TOR, pm-TOR, PI3K, p-PI3K and Akt protein levels.

Copper doped titanium dioxide-polypyrrole (Cu-TiO2/PPY) composite was successfully synthesized via chemical oxidative in-situ polymerization process. The structural and morphological properties of Cu-TiO2/PPY composite were investigated using X-ray diffractometer (XRD), field emission electron microscopy (FESEM) and transmission electron microscopy(TEM) techniques. The electrochemical properties of as-synthesized composite were studied using cyclic voltammetry (CV), galvanostatic charge discharge (GCD) and electrochemical impedance spectroscopic (EIS) techniques. The novel Cu-TiO2/PPY composite showed enhanced volumetric capacitance ˜714 F cm-1 and gravimetric capacitance ˜674 F g-1 at 1 A g-1. In addition an excellent coulombic efficiency and comparabley low charge transfer resistance than pure PPY suggests improved supercapacitive performance of Cu-TiO2/PPY composite as an electrode material.

A search for the $C\\!P$-violating strong decays $\\eta \\to \\pi^+\\pi^-$ and $\\eta^\\prime(958) \\to \\pi^+\\pi^-$ has been performed using approximately $2.5 \\times 10^{7}$ events of each of the decays $D^+ \\to \\pi^+\\pi^+\\pi^-$ and $D_s^+ \\to \\pi^+\\pi^+\\pi^-$, recorded by the LHCb experiment. The data set corresponds to an integrated luminosity of 3.0 fb$^{-1}$ of $pp$ collision data recorded during LHC Run 1 and 0.3 fb$^{-1}$ recorded in Run 2. No evidence is seen for $D^+_{(s)} \\to \\pi^+ \\eta^{(\\prime)}$ with $\\eta^{(\\prime)} \\to \\pi^+\\pi^-$, and upper limits at 90% confidence level are set on the branching fractions, $\\mathcal{B}(\\eta \\to \\pi^+\\pi^-) < 1.6 \\times 10^{-5}$ and $\\mathcal{B}(\\eta^\\prime \\to \\pi^+\\pi^-) < 1.8 \\times 10^{-5}$. The limit for the $\\eta$ decay is comparable with the existing one, while that for the $\\eta^\\prime$ is a factor of three smaller than the previous limit.

Bacterial and fungal infections in the use of surgical devices and medical implants remain a major concern. Traditional bioadhesives fail to incorporate anti-microbial properties, necessitating additional anti-microbial drug injection. Herein, by the introduction of the clinically used and inexpensive anti-fungal agent, 10-undecylenic acid (UA), into our recently developed injectable citrate-based mussel-inspired bioadhesives (iCMBAs), a new family of anti-bacterial and anti-fungal iCMBAs (AbAf iCs) was developed. AbAf iCs not only showed strong wet tissue adhesion strength, but also exhibited excellent in vitro cyto-compatibility, fast degradation, and strong initial and considerable long-term anti-bacterial and anti-fungal ability. For the first time, the biocompatibility and anti-microbial ability of sodium metaperiodate (PI), an oxidant used as a cross-linking initiator in the AbAf iCs system, was also thoroughly investigated. Our results suggest that the PI-based bioadhesives showed better anti-microbial properties compared to the unstable silver-based bioadhesive materials. In conclusion, AbAf iCs family can serve as excellent anti-bacterial and anti-fungal bioadhesive candidates for tissue/wound closure, wound dressing, and bone regeneration, especially when bacterial or fungal infections are a major concern.

The results of a search for a possible evidence of a pi /sup +/ pi /sup +/ resonant state in the np to pi /sup +/ pi /sup +/ pi /sup -/ annihilation reaction with data collected by the OBELIX Experiment are presented. The study has been performed by means of a partial wave analysis in the frame of the isobar model. Production fractions for a possible pi /sup +/ pi /sup +/ resonance have been evaluated. The observed effects at the pi /sup +/ pi /sup +/ threshold may be described reasonably well by the contributions of f/sub 2/(1270), f /sub 0/(1500), f/sub 2/(1565) and rho (1450) states and their interferences, but a meaningful statistical indication for a pi /sup +/ pi /sup +/ scalar state at about 1400 MeV emerges from the analysis.

Thermal polymerization of pyrrole was performed using silver nitrate as source of silver ions followed by its conversion to Polypyrrole (PPy)/Ag nano-comoposites without using any external oxidizing agent or solvent. The formation of PPy was monitored by UV-Visible absorption spectroscopy showing a band at approximately 464 nm. XRD measurement confirmed characteristic peaks for face centered cubic (fcc) silver and presence of PPy at 2 theta of approximately 23 degrees suggesting the formation of PPy/Ag nanocomposite. Transmission electron microscopy (TEM) images showed non-aggregated spherical Ag nano-particles of about 5-10 nm. PPy/Ag thick film acts as a NH3 sensor at 100 degrees C, a H2S sensor at 250 degrees C and CO2 sensor at 350 degrees C. The thick films showed capability to recognize various gases at different operating temperature.

Production of {pi}{sup 0}{pi}{sup 0} and {pi}{sup +}{pi}{sup +} pairs in proton-proton collisions

Energy Technology Data Exchange (ETDEWEB)

Skorodko, Tatiana

2009-07-17

The {pi}{sup 0}{pi}{sup 0} production in proton-proton collisions has been measured in the energy range from threshold up to 1.3 GeV using the WASA 4{pi} detector setup with an internal pellet target at the CELSIUS storage ring in Uppsala. In addition the {pi}{sup +}{pi}{sup +} production has been measured at an incident energy of 1.1 GeV. The {pi}{sup 0}{pi}{sup 0} and {pi}{sup +}{pi}{sup +} data taken at WASA constitute the first exclusively measured samples of solid statistics in the considered energy range. Total and differential cross sections for the pp{yields}pp{pi}{sup 0}{pi}{sup 0} and pp{yields}nn{pi}{sup +}{pi}{sup +} reactions are systematically compared to the Valencia model predictions. At incident energies close to threshold, i.e. up to 0.9 GeV, the {pi}{sup 0}{pi}{sup 0} data can be successfully explained by excitation and decay of the Roper resonance. Its direct decay into the N{sigma} channel is found to be by far the dominating two-pion decay process. in favor of a monopole excitation of the Roper resonance. At energy T{sub p}>1 GeV, i.e. in the energy region, which is beyond the Roper excitation but at the onset of {delta}{delta} excitation, a behavior is observed which is different from the theoretical prediction both in differential and total cross sections. The differential cross sections for {pi}{sup 0}{pi}{sup 0} channel in the {delta}{delta} region can be described, if the special configuration ({delta}{delta}){sub 0} is assumed. Moreover, the {pi}{sup 0}{pi}{sup 0} data exhibit a small systematic low-mass enhancement in the {pi}{sup 0}{pi}{sup 0} invariant mass spectrum. The total pp{pi}{sup 0}{pi}{sup 0} cross sections fall behind theoretical predictions, whereas the nn{pi}{sup +}{pi}{sup +} cross section is a factor of five larger that expected. A model-unconstrained isospin decomposition of the total cross sections points to a s-channel-like energy dependence of the Roper excitation as well as to a significant contribution of an

Una delle ricerche più interessanti è quella che ha portato ad utilizzare, per scopi analitici, tecnologie legate alla cosiddetta Intelligenza Artificiale (IA, una disciplina nata verso la fine degli anni Cinquanta con lo scopo di simulare l'intelligenza mediante un sistema computerizzato. In mancanza di una definizione univoca di intelligenza, un primo gruppo di ricercatori del MIT (Massachusetts Institute of Tecnology, diretti da Marvin Minsksy, assunse come paradigma di riferimento l'intelligenza umana e, in una delle ricerche più avanzate nel campo, le cosiddette reti neurali (neural networks.

We have performed the most comprehensive resonance-model fit of $ \\pi^-\\pi^-\\pi^+$ states using the results of our previously published partial-wave analysis (PWA) of a large data set of diffractive-dissociation events from the reaction $\\pi^- +p \\to \\pi^-\\pi^-\\pi^+ +p_{recoil}$ with a 190 GeV/${\\it c}$ pion beam. The PWA results, which were obtained in 100~bins of three-pion mass, 0.5 < ~$m_{3\\pi}$ < 2.5 GeV/${\\it c}$$^2$, and simultaneously in 11~bins of the reduced four-momentum transfer squared, 0.1 < $t'$ < 1.0 (GeV/${\\it c}$)$^2$, are subjected to a resonance-model fit using Breit-Wigner amplitudes to simultaneously describe a subset of 14~selected waves using 11~isovector light-meson states with $J^{PC} = 0^{-+}$, $1^{++}$, $2^{++}$, $2^{-+}$, $4^{++}$, and spin-exotic $1^{-+}$ quantum numbers. The model contains the well-known resonances $\\pi$(1800), $a_1$(1260), $a_2$(1320), $\\pi_2$(1670), $\\pi_2$(1880), and $a_4$(2040). In addition, it includes the dispute...

Performance of the Chemical and Electrochemical Composites of PPy/CNT as Electrodes in Type I Supercapacitors

Full Text Available Polypyrrole (PPy is one of the most studied conducting polymers and a very promising material for various applications such as lithium-ion secondary batteries, light-emitting devices, capacitors, and supercapacitors, owing to its many advantages, including good processability, easy handling, and high electronic conductivity. In this work, PPy films were chemically and electrochemically synthesized, both in and around carbon nanotubes (CNTs. The cyclic voltammograms of the device, composed of the electrochemically synthesized PPy/CNT composites as working and counter electrodes (Type I supercapacitor with p-type doping, showed a predominantly capacitive profile with low impedance values and good electrochemical stability, with the anodic charge remaining almost constant (11.38 mC, a specific capacitance value of 530 F g−1 after 50 charge and discharge cycles, and a coulombic efficiency of 99.2%. The electrochemically synthesized PPy/CNT composite exhibited better electrochemical properties compared to those obtained for the chemically synthesized composite. Thus, the electrochemically synthesized PPy/CNT composite is a promising material to be used as electrodes in Type I supercapacitors.

Measurements of B{sup 0} Decays to pi{sup +}pi{sup -}pi{sup 0}

We present preliminary results of searches for exclusive B{sup 0} decays to {pi}{sup +}{pi}{sup -} {pi}{sup 0} among 22.7 million b{bar b} pairs collected by the BABAR experiment from electron-positron collisions near the {Upsilon}(4S) resonance. We measure {Beta}(B{sup 0} {yields} {pi}{sup {+-}}) = (28.9 {+-} 5.4 {+-} 4.3) x 10{sup 6}, and find no evidence for the presence of any other decay mode in the {pi}{sup +}{pi}{sup -} {pi}{sup 0} Dalitz plot. Upper limits are determined for the branching fractions of B{sup 0} {yields} {sup 0}{pi}{sup 0}, non-resonant B{sup 0} decays to {pi}{sup +}{pi}{sup -} {pi}{sup 0} and of several discrete regions of {pi}{sup +}{pi}{sup -} {pi}{sup 0} phase-space. We also measure the direct CP-violating asymmetry between the rates of untagged {sup +}{pi}{sup -} and {sup -}{pi}{sup +}, finding no significant evidence for an effect.

PI3Kδ-selective and PI3Kα/δ-combinatorial inhibitors in clinical development for B-cell non-Hodgkin lymphoma.

The efficacy of the prototypical phosphatidylinositol-3-kinase (PI3K) inhibitor idelalisib for the treatment of chronic lymphocytic leukemia (CLL) and indolent non-Hodgkin lymphoma (iNHL) has led to development of multiple compounds targeting this pathway. Areas Covered: We review the hypothesized therapeutic mechanisms of PI3K inhibitors, including abrogation of B cell receptor signaling, blockade of microenvironmental pro-survival signals, and enhancement of anti-tumor immunity. We examine toxicities of idelalisib, including bacterial infections (possibly secondary to drug-induced neutropenia), opportunistic infections (possibly attributable to on-target inhibition of T cell function), and organ toxicities such as transaminitis and enterocolitis (possibly autoimmune, secondary to on-target inhibition of p110δ in regulatory T cells). We evaluate PI3K inhibitors that have entered trials for the treatment of lymphoma, focusing on agents with selectivity for PI3Kα and PI3Kδ. Expert Opinion: PI3K inhibitors, particularly those that target p110δ, have robust efficacy in the treatment of CLL and iNHL. However, idelalisib has infectious and autoimmune toxicities that limit its use. Outside of trials, idelalisib should be restricted to CLL patients with progression on ibrutinib or iNHL patients with progression on two prior therapies. Whether newer PI3K inhibitors will demonstrate differentiated toxicity profiles in comparable patient populations while retaining efficacy remains to be seen.

An analysis of the decays of $B^\\mp \\rightarrow D K^\\mp$ and $B^\\mp \\rightarrow D \\pi^\\mp $ is presented in which the $D$ meson is reconstructed in the three-body final states $K^\\mp \\pi^\\pm \\pi^0$, $\\pi^+ \\pi^- \\pi^0$ and $K^+ K^- \\pi^0$. Using data from LHCb corresponding to an integrated luminosity of 3.0~fb$^{-1}$ of $pp$ collisions, measurements of several $CP$ observables are performed. First observations are obtained of the suppressed ADS decay $B^\\mp \\rightarrow [\\pi^\\mp K^\\pm \\pi^0]_D \\pi^\\mp$ and the quasi-GLW decay $B^\\mp \\rightarrow [K^+ K^- \\pi^0]_D \\pi^\\mp$. The results are interpreted in the context of the unitarity triangle angle $\\gamma$ and related parameters.

The decay $B_c^+\\to J/\\psi \\pi^+\\pi^-\\pi^+$ is observed for the first time, using 0.8 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s}=7$ TeV collected by the LHCb experiment. The ratio of branching fractions ${\\cal B}(B_c^+\\to J/\\psi \\pi^+\\pi^-\\pi^+)/{\\cal B}(B_c^+\\to J/\\psi \\pi^+)$ is measured to be $2.41\\pm0.30\\pm0.33$, where the first uncertainty is statistical and the second systematic. The result is in agreement with theoretical predictions.

Full Text Available Die orale Medikation mit Sildenafil (Viagra™ hat sich zur Therapie der erektilen Dysfunktion etabliert und relativiert die Differentialdiagnose zwischen psychogener und organischer Dysfunktion mit den entsprechenden therapeutischen Konsequenzen. Diesem Problem widmet sich diese Studie zur Prüfung der erektilen Antwort unter RigiScan®-Monitoring ohne/mit 50 mg Viagra™. 64 Patienten (mittleres Alter 48 Jahre mit einer erektilen Dysfunktion arteriogener (n = 10, venöser (n = 7, gemischt neurogen/vaskulärer (n = 15 und psychogener (n = 32 Genese von mehr als 6 Monaten Dauer wurden in die Studie aufgenommen. Alle Patienten wurden eingehend diagnostisch abgeklärt, inklusive Hormonlabor, dynamischer Pharmako-Duplexsonographie und, falls indiziert, mit einer Cavernosometrie/ -graphie. Zur Testung der penilen Rigidität und zur Objektivierung der Erektion wurde das "real-time" RigiScan® verwendet. In zwei konsekutiven Messungen wurden sowohl die direkte erektile Antwort auf visuelle Stimulation als auch die nächtlichen Erektionen abgeleitet und die Meßergebnisse mit den Begleiterkrankungen, "lifestyle"-Faktoren und dem Ergebnis der Pharmako-Duplexsonographie korreliert. Es fand sich keine Korrelation zwischen der Ätiologie der erektilen Dysfunktion in bezug auf organische oder psychogene Genese und dem Alter der Patienten, der Dauer der Erektionsstörung, dem Nikotinabusus, den Blutfetten, den Testosteronwerten, dem klinischen Ergebnis der Pharmakotestung (Erektionsgrad und dem duplexsonographisch gemessenen Fluß der penilen Arterien. Hingegen zeigte sich eine positive Korrelation zwischen Genese der erektilen Dysfunktion (organisch bzw. psychogen und dem RigiScan®-Meßergebnis (r = 0,29. Patienten mit psychogen bedingter Erektionsstörung profitierten am meisten von Viagra™, während Patienten mit vaskulärer Genese oder gemischt neurogener/vaskulärer Genese deutlich schlechter auf Viagra™ ansprachen. Es bestand keine Korrelation

First observations of the Cabibbo suppressed decays $\\bar{B}^0\\to D^+K^-\\pi^+\\pi^-$ and $B^-\\to D^0K^-\\pi^+\\pi^-$ are reported using 35~pb$^{-1}$ of data collected with the LHCb detector. Their branching fractions are measured with respect to the corresponding Cabibbo favored decays, from which we obtain ${\\cal{B}}(\\bar{B}^0\\to D^+K^-\\pi^+\\pi^-)/{\\cal{B}}(\\bar{B}^0\\to D^+\\pi^-\\pi^+\\pi^-)=(5.9\\pm1.1\\pm0.5)\\times10^{-2}$ and ${\\cal{B}}(B^-\\to D^0K^-\\pi^+\\pi^-)/{\\cal{B}}(B^-\\to D^0\\pi^-\\pi^+\\pi^-)=(9.4\\pm1.3\\pm0.9)\\times10^{-2}$, where the uncertainties are statistical and systematic, respectively. The $B^-\\to D^0K^-\\pi^+\\pi^-$ decay is particularly interesting, as it can be used in a similar way to $B^-\\to D^0K^-$ to measure the CKM phase $\\gamma$.

While documented plans for patient and public involvement (PPI) in research are required in many grant applications, little is known about how frequently PPI occurs in practice. Low levels of reported PPI may mask actual activity due to limited PPI reporting requirements. This research analysed the frequency and types of reported PPI in the presence and absence of a journal requirement to include this information. A before and after comparison of PPI reported in research papers published in The BMJ before and 1 year after the introduction of a journal policy requiring authors to report if and how they involved patients and the public within their papers. Between 1 June 2013 and 31 May 2014, The BMJ published 189 research papers and 1 (0.5%) reported PPI activity. From 1 June 2015 to 31 May 2016, following the introduction of the policy, The BMJ published 152 research papers of which 16 (11%) reported PPI activity. Patients contributed to grant applications in addition to designing studies through to coauthorship and participation in study dissemination. Patient contributors were often not fully acknowledged; 6 of 17 (35%) papers acknowledged their contributions and 2 (12%) included them as coauthors. Infrequent reporting of PPI activity does not appear to be purely due to a failure of documentation. Reporting of PPI activity increased after the introduction of The BMJ 's policy, but activity both before and after was low and reporting was inconsistent in quality. Journals, funders and research institutions should collaborate to move us from the current situation where PPI is an optional extra to one where PPI is fully embedded in practice throughout the research process. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The most common methods for the drug delivery are swallowing pills or receiving injections. However, formulations that control the rate and period of medicine (i.e., time-release medications) are still problematic. The proposed implantable devices which include batteries, sensors, telemetry, valves, and drug storage reservoirs provide an alternative method for the responsive drug delivery system [1]. Using this device, drug concentration can be precisely controlled which enhances drug efficiency and decreases the side effects. In order to achieve responsive drug delivery, a reliable release valve has to be developed. Biocompatibility, low energy consumption, and minimized leakage are the main requirements for such release method. A bilayer structure composed of Au/PPy film is fabricated as a flap to control the release valve. Optimized potentiostatic control to synthesize polypyrrole (PPy) is presented. The release of miniaturize valve is tested and showed in this paper. A novel idea to simultaneously fabricate the device reservoirs as well as protective packaging is proposed in this paper. The solution of PDMS permeability problem is also mentioned in this article.

Monitoring of unfractionated heparin with rotational thrombelastometry using the prothrombinase-induced clotting time reagent (PiCT®).

To achieve sufficient and safe anticoagulation with unfractionated heparin (UFH) a close and reliable drug monitoring is necessary. In general, the activated partial thromboplastin time (APTT) is used for this purpose. In acute phase response, however, the APTT test procedure might be unreliable e.g. with false low results in the presence of elevated factor VIII. In this so called heparin resistance, measurement of anti-Xa activity is recommended over APTT to avoid potentially harmful dose escalation. A combination of anti-Xa measurement and global hemostatic testing with ROTEM® employing the anti-Xa sensitive PiCT® reagent showed high correlation with enoxaparin levels. This test modification could also be suitable for monitoring UFH. Aim of the study was to evaluate the correlation between PiCT®-ROTEM® and levels of UFH. In this in-vitro study blood samples from healthy volunteers were spiked with UFH and subjected to different ROTEM® tests. There was a linear correlation between UFH level and clotting time (CT) in the PiCT®-ROTEM® test with an excellent correlation coefficient of 0.92. Additional endpoints showed similar results (PiCT®-ROTEM® MaxVel r = -0.85 and PiCT®-ROTEM® t_MaxVel r = 0.88). As a point-of-care applicable tool ROTEM® is immediately at hand.

Development organisations need easy-to-use and quick-to-implement indicators to quantify poverty when requested to measure program impact. In this paper we assess the validity of the Progress out of Poverty Index (PPI)™, a country-specific indicator based on ten closed questions on directly observable household characteristics, by its compliance to the SMART criteria. Each response receives a pre-determined score, such that the sum of these scores can be converted into the likelihood the household is living below the poverty line. We focus on the PPI scorecard for Rwanda, which was validated using two national household surveys conducted in 2005/06 and 2010/11. The PPI is Specific, Measurable, Available cost effectively, and Timely available. Yet, its Relevance depends on the way it is used. Although it accurately distinguishes poor from non-poor households, making it a useful reporting tool, its limited sensitivity to changes in poverty status restricts its usefulness for evaluating the impact of development projects.

We present measurements of the branching fractions and CP violation parameters for the decay channels B{sup 0}{yields}{pi}{sup +}{pi}{sup -}, B{sup 0}{yields}K{sup +}{pi}{sup -} and B{sup 0}{yields}K{sup +}K{sup -}. The final Belle dataset of 772 million B anti B pairs produced at the {Upsilon}(4S) resonance at the KEKB asymmetric-energy e{sup +}e{sup -} collider is used. For the branching fractions, we obtain B(B{sup 0}{yields}{pi}{sup +}{pi}{sup -})=(5.63{+-} 0.16(stat){+-} 0.16(syst)) x 10{sup -6}, B(B{sup 0}{yields}K{sup {+-}}{pi}{sup -+})=(18.71{+-}0.25(stat){+-} 0.37(syst)) x 10{sup -6}, B(B{sup 0}{yields}K{sup +}K{sup -})<14 x 10{sup -8} at 90% CL. For the CP-asymmetries, we obtain following values: A{sub CP}(B{sup 0}{yields}{pi}{sup +}{pi}{sup -})=0.33{+-}0.06(stat){+-}0.03 (syst), S{sub CP}(B{sup 0}{yields}{pi}{sup +}{pi}{sup -})=-0.64{+-}0.08(stat){+-}0.03(syst), A{sub CP}(B{sup 0}{yields}K{sup {+-}}K{sup -+})=-0.061{+-}0.014(stat){+-}0.008 (syst), where A{sub CP} and S{sub CP} represent direct and mixing-induced CP violation, respectively. For the CP-violating weak phase {phi}{sub 2} we exclude the region 23.8 <{phi}{sub 2}<66.8 at the 1{sigma} level. A model independent test of new physics using a sum rule in the K{pi} system yields a mild deviation from the standard model of -0.289{+-}0.139(stat){+-}0.064(syst) with a 1.9{sigma} significance.

Identifying protein complex by integrating characteristic of core-attachment into dynamic PPI network.

Directory of Open Access Journals (Sweden)

Xianjun Shen

Full Text Available How to identify protein complex is an important and challenging task in proteomics. It would make great contribution to our knowledge of molecular mechanism in cell life activities. However, the inherent organization and dynamic characteristic of cell system have rarely been incorporated into the existing algorithms for detecting protein complexes because of the limitation of protein-protein interaction (PPI data produced by high throughput techniques. The availability of time course gene expression profile enables us to uncover the dynamics of molecular networks and improve the detection of protein complexes. In order to achieve this goal, this paper proposes a novel algorithm DCA (Dynamic Core-Attachment. It detects protein-complex core comprising of continually expressed and highly connected proteins in dynamic PPI network, and then the protein complex is formed by including the attachments with high adhesion into the core. The integration of core-attachment feature into the dynamic PPI network is responsible for the superiority of our algorithm. DCA has been applied on two different yeast dynamic PPI networks and the experimental results show that it performs significantly better than the state-of-the-art techniques in terms of prediction accuracy, hF-measure and statistical significance in biology. In addition, the identified complexes with strong biological significance provide potential candidate complexes for biologists to validate.

To date there have been no clear features that aid in differentiating patients with eosinophilic oesophagitis (EoE) from PPI-responsive oesophageal eosinophilia (PPI-REE). However, barium swallow roentgenography is a more sensitive and specific measure to detect subtle fibrostenotic remodeling changes present in EoE. We aim to characterise any clinical, endoscopic, histiological or barium roentgenographic differences between EoE and PPI-REE. To characterise any clinical, endoscopic, histiological or barium roentgenographic differences between EoE and PPI-REE. We performed a retrospective cohort analysis on data collected from a tertiary referral centre population from 2010 to 2015. Data from 66 patients with EoE and 28 patients with PPI-REE were analysed. Cases were adults who met consensus guidelines for EOE, and had a barium swallow study within 6 months of the index endoscopy. Clinical, endoscopic, histiological and barium swallow findings were collected. Patients with EoE reported similar characteristics as PPI-REE patients, except EoE patients were younger (35.6 vs. 46.6 years; P = 0.011), had earlier symptom onset (29.0 vs. 38.0 years; P = 0.026), and smaller oesophageal diameters on barium swallow (19.5 mm vs. 20; P = 0.042). Patients with EoE were more likely to have distal strictures (EoE 77% vs. 25%; P = 0.02) and, importantly, a greater likelihood of small calibre oesophagus (51.5% vs. 17.9%; P = 0.002). Moreover, EoE patients had a higher probability of developing small calibre oesophagus after 20 years of symptoms (72.3% vs. 30.2%; P = 0.074) compared to PPI-REE patients. When compared with eosinophilic oesophagitis, PPI-REE patients demonstrate findings that suggest PPI-responsive oesophageal eosinophilia to be a later onset, less aggressive form of oesophageal stricturing disease than eosinophilic oesophagitis. © 2016 John Wiley & Sons Ltd.

Full Text Available Well-regulated DC bus voltage is the important point to guarantee the power demand in hybrid vehicle applications. Voltage regulation can be achieved with control method that build switching signal on DC-DC converter. This paper describes design and small scale experimental results of bus voltage regulation control of the DC-DC bidirectional converter with battery and supercapacitor as energy source. The control system consists of two control loops, the outer loop that get DC bus voltage feedback using PI anti-windup back calculation control method. This outer loop will generate a reference current for the inner loop that implement hysteresis control. The inner control loop will compare that reference curent with the source current obtained from the current sensor. Simulation and experimental results show that bus voltage is well-regulated under the load changes with 1% voltage ripple.

Evolutionary, kinetic and thermodynamic aspects on the bioenergetics of inorganic pyrophosphate (PPi) and adenosine triphosphate (ATP)

1995-01-01

Energy barriers for energy carriers are of fundamental significance for the successful operation of the bioenergetic reactions in living cells. PPi and ATP are outstanding ''energy-rich'' examples of molecular ''energy currencies'' in biological systems, with kinetic barriers preventing excessively fast thermodynamically feasible hydrolysis from occurring. The barriers may be considered to facilitate the energy coupling roles of these phosphate compounds, which are to secure growth and maintain numerous other energy requiring functions. The enzymes involved in overcoming the energies of activation of the bioenergetic reactions have evolved to be very well tuned for their roles. Three aspects will be discussed in some detail. The first is the fact that ATP at neutral pH is considerably more energy-rich than PPi, which thus has been called a ''poor man's ATP''. This is exemplified by the kinetic and thermodynamic differences observed between the requirements for the photosynthetic formation of PPi and ATP in certain photobacterial chromatophores by varying levels of energy supply. At lower pH, PPi and ATP are equally energy-rich, which may be of significance for acidophiles. The second concerns the possible evolutionary significance of the finding that, in the dark, a pH gradient suffices to drive extensive PPi synthesis, whereas ATP synthesis requires both a pH gradient and a membrane potential (Strid et al, Biochim. Biophys. Acta 892 (1987) 236-244). Thirdly, PPi as the most plausible predecessor to ATP in the origin and early evolution of life, will be discussed. (author). Abstract only

Measurement of Global Solar Radiation data using Raspberry Pi and its estimation using Genetic Algorithm

Full Text Available The demand for more efficient and environmentally benign, non-conventional sources of energy came into picture due to increasing demands for human comforts. Solar energy is now the ultimate option. In this paper, the instruments used to measure the solar radiation at Innovation Centre, MIT Manipal were connected to a Raspberry Pi to access the data remotely. Genetic Algorithms were formulated, so that the monthly mean global solar radiation in Manipal can be effectively estimated. Meteorological data such as humidity, temperature, wind speed, etc. were used as inputs to train the networks. A successful network was made between the data loggers and the Raspberry Pi. The data collected by the data loggers from the devices are transmitted to the Raspberry Pi which in turn sends the data to an internal server. The Raspberry Pi can be accessed using any SSH client such as PuTTY. The meteorological data was collected for the years 2010-2014 in order to formulate the Artificial Intelligence models. The validity of the formulated models were checked by comparing the measured data with the estimated data using tools such as RMSE, correlation coefficient, etc. The modelling of solar radiation using GA was carried out in GeneXpro tools version 5.0.

Highlights: ► SA chromophore groups are formed by bonding terminal groups to PPI dendrimers. ► SA chromophore groups reveal four most stable tautomeric forms. ► Tautomeric properties of SA groups depend on the dendrimer generation and solvent. ► Aggregation of SA chromophores facilitates formation of the trans-keto tautomers. ► Fluorescence of PPI SA dendrimers is attributed to nπ ∗ states of keto tautomers. -- Abstract: Bonding of the promesogenic unit derived from 4-(4′-ethoxybenzoyloxy)salicylaldehyde to the amino terminated PPI dendrimer chains results in formation of the salicylidenimine chromophore groups. Absorption and fluorescence investigations of the dendrimer solutions supported by the quantum chemistry calculations revealed that the chromophore groups may exist in enol and keto tautomeric forms with relative concentrations depending on the dendrimer generation and solvent. The dendrimer fluorescence is attributed to nπ ∗ states of keto tautomers which may also be formed from excited enol tautomers.

Preparation of stable magnetic nanofluids containing Fe3O4@PPy nanoparticles by a novel one-pot route

Full Text Available Abstract Stable magnetic nanofluids containing Fe3O4@Polypyrrole (PPy nanoparticles (NPs were prepared by using a facile and novel method, in which one-pot route was used. FeCl3·6H2O was applied as the iron source, and the oxidizing agent to produce PPy. Trisodium citrate (Na3cit was used as the reducing reagent to form Fe3O4 NPs. The as-prepared nanofluid can keep long-term stability. The Fe3O4@PPy NPs can still keep dispersing well after the nanofluid has been standing for 1 month and no sedimentation is found. The polymerization reaction of the pyrrole monomers took place with Fe3+ ions as the initiator, in which these Fe3+ ions remained in the solution adsorbed on the surface of the Fe3O4 NPs. Thus, the core-shell NPs of Fe3O4@PPy were obtained. The particle size of the as-prepared Fe3O4@PPy can be easily controlled from 7 to 30 nm by the polymerization reaction of the pyrrole monomers. The steric stabilization and weight of the NPs affect the stability of the nanofluids. The as-prepared Fe3O4@PPy NPs exhibit superparamagnetic behavior.

A study of the reaction {pi}{sup -} p {yields} p {pi}{sup +}{pi}{sup -}{pi}{sup -} at 2.75 GeV/c was carried out in an 81 cm liquid hydrogen bubble chamber at the CERN proton synchrotron. One observes that the abundant N{sub 33}{sup *++} (1236 MeV) isobar production occurs predominantly backwards in the center of mass of the reaction. This feature suggests a peripheral production mechanism with {pi} exchange. The validity of this hypothesis, which allows the study of the {pi}{sup -}{pi}{sup -} interaction within the frame of the Chew and Low model, is verified. Among other results one finds for the isospin-2 state the values of the elastic {pi}{pi} cross section and of the S and D wave phase shifts.

PPI-IRO: A two-stage method for protein-protein interaction extraction based on interaction relation ontology

KAUST Repository

Li, Chuanxi

2014-01-01

Mining Protein-Protein Interactions (PPIs) from the fast-growing biomedical literature resources has been proven as an effective approach for the identifi cation of biological regulatory networks. This paper presents a novel method based on the idea of Interaction Relation Ontology (IRO), which specifi es and organises words of various proteins interaction relationships. Our method is a two-stage PPI extraction method. At fi rst, IRO is applied in a binary classifi er to determine whether sentences contain a relation or not. Then, IRO is taken to guide PPI extraction by building sentence dependency parse tree. Comprehensive and quantitative evaluations and detailed analyses are used to demonstrate the signifi cant performance of IRO on relation sentences classifi cation and PPI extraction. Our PPI extraction method yielded a recall of around 80% and 90% and an F1 of around 54% and 66% on corpora of AIMed and Bioinfer, respectively, which are superior to most existing extraction methods.

Measurements of double-differential charged pion production cross-sections in interactions of 12 GeV/c protons on O_2 and N_2 thin targets are presented in the kinematic range 0.5 GeV/c < p_{\\pi} < 8 GeV/c and 50 mrad < \\theta_{\\pi} < 250 mrad (in the laboratory frame) and are compared with p--C results. For p--N_2 (p--O_2) interactions the analysis is performed using 38576 (7522) reconstructed secondary pions. The analysis uses the beam instrumentation and the forward spectrometer of the HARP experiment at CERN PS. The measured cross-sections have a direct impact on the precise calculation of atmospheric neutrino fluxes and on the improved reliability of extensive air shower simulations by reducing the uncertainties of hadronic interaction models in the low energy range. In particular, the present results allow the common hypothesis that p--C data can be used to predict the p--N_2 and p--O_2 pion production cross-sections to be tested.

The K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} decay mode was investigated using the data collected in 2002 by the NA48/1 Collaboration. With about 23 k K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} events and 59 k K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0} normalization decays, the K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} branching ratio relative to the K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0} one was determined to be BR(K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -})/BR(K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0})=(3.28{+-}0.06{sub stat{+-}}0.04{sub syst})x10{sup -2}. This result was used to set the upper limit |g{sub E1}/g{sub BR}|<3.0 at 90% CL on the presence, in the decay amplitude, of an E1 direct emission (g{sub E1}) term relative to the dominant inner bremsstrahlung (g{sub BR}) term. The CP-violating asymmetry A{sub {phi}} in the sin{phi}cos{phi} distribution of K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} events, where {phi} is the angle between the {pi}{sup +{pi}-} and the e{sup +}e{sup -} decay planes in the kaon centre of mass, was found to be A{sub {phi}=}(-0.4{+-}0.8)%, consistent with zero. These results are in good agreement with a description of the K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} decay amplitude dominated by the CP-even inner bremsstrahlung process.

The exclusive electroproduction process $\\vec{e}p \\to e^\\prime n \\pi^+$ was measured in the range of the photon virtuality $Q^2 = 1.7 - 4.5 \\rm{GeV^2}$, and the invariant mass range for the $n\\pi^+$ system of $W = 1.15 - 1.7 \\rm{GeV}$ using the CEBAF Large Acceptance Spectrometer. For the first time, these kinematics are probed in exclusive $\\pi^+$ production from protons with nearly full coverage in the azimuthal and polar angles of the $n\\pi^+$ center-of-mass system. The $n\\pi^+$ channel has particular sensitivity to the isospin 1/2 excited nucleon states, and together with the $p\\pi^0$ final state will serve to determine the transition form factors of a large number of resonances. The largest discrepancy between these results and present modes was seen in the $\\sigma_{LT'}$ structure function. In this experiment, 31,295 cross section and 4,184 asymmetry data points were measured. Because of the large volume of data, only a reduced set of structure functions and Legendre polynomial moments can be presented that are obtained in model-independent fits to the differential cross sections.

Graphical abstract: A novel tube-in-tube nanostructured PPy/MnO 2 /CNTs composite have been successfully fabricated. Its inner tubules are CNTs and the outer tubules are template-synthesized PPy. Most MnO 2 nanoparticles are sandwiched between the inner and outer wall, some relatively large particles are also latched onto the outside wall of the PPy tube. The composite yields a good electrochemical reversibility through 1000 cycles’ cyclic voltammogram (CV) test and galvanostatic charge–discharge experiments at different current densities. Display Omitted Highlights: ► We fabricate a ternary organic–inorganic complex of PPy/MnO 2 /CNTs composite. ► We characterize its morphological structures and properties by several techniques. ► The composite possesses the typical tube-in-tube nanostructures. ► Most MnO 2 nanoparticles are sandwiched between the inner CNTs and outer PPy wall. ► The composite has good electrochemical reversibility for supercapacitor. -- Abstract: Ternary organic–inorganic complex of polypyrrole/manganese dioxide/carbon nanotubes (PPy/MnO 2 /CNTs) composite was prepared by in situ chemical oxidation polymerization of pyrrole in the host of inorganic matrix of MnO 2 and CNTs, using complex of methyl orange (MO)/FeCl 3 was used as a reactive self-degraded soft-template. The morphological structures of the composite were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopic (HRTEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD), respectively. All the results indicate that the PPy/MnO 2 /CNTs composite possesses the typical tube-in-tube nanostructures: the inner tubules are CNTs and the outer tubules are template-synthesized PPy. MnO 2 nanoparticles may either sandwich the space between the inner and outer tubules or directly latch onto the wall of the PPy tubes. The composite yields a good electrochemical

Phosphate Activation via Reduced Oxidation State Phosphorus (P. Mild Routes to Condensed-P Energy Currency Molecules

Full Text Available The emergence of mechanisms for phosphorylating organic and inorganic molecules is a key step en route to the earliest living systems. At the heart of all contemporary biochemical systems reside reactive phosphorus (P molecules (such as adenosine triphosphate, ATP as energy currency molecules to drive endergonic metabolic processes and it has been proposed that a predecessor of such molecules could have been pyrophosphate [P2O74−; PPi(V]. Arguably the most geologically plausible route to PPi(V is dehydration of orthophosphate, Pi(V, normally a highly endergonic process in the absence of mechanisms for activating Pi(V. One possible solution to this problem recognizes the presence of reactive-P containing mineral phases, such as schreibersite [(Fe,Ni3P] within meteorites whose abundance on the early Earth would likely have been significant during a putative Hadean-Archean heavy bombardment. Here, we propose that the reduced oxidation state P-oxyacid, H-phosphite [HPO32−; Pi(III] could have activated Pi(V towards condensation via the intermediacy of the condensed oxyacid pyrophosphite [H2P2O52−; PPi(III]. We provide geologically plausible provenance for PPi(III along with evidence of its ability to activate Pi(V towards PPi(V formation under mild conditions (80 °C in water.

Rational use of nonsteroidal anti-inflammatory drugs and proton pump inhibitors in combination for rheumatic diseases

Full Text Available Wolfgang W BoltenDivision of Rheumatology, Klaus-Miehlke Klinik, Wiesbaden, GermanyAbstract: Nonsteroidal anti-inflammatory drugs (NSAIDs are successfully used to alleviate pain and inflammation in rheumatic diseases. In an appreciable percentage of cases, the use of systemic NSAIDs is associated with adverse lesions of the gastrointestinal (GI mucosa up to life-threatening perforations, ulcers, and bleeding. Reliable warning signals mostly do not arise. Therefore, it is important to take preventive measures to reduce the GI risk. One established method is to assign cyclooxygenase 2 (COX-2-specific inhibitors (coxibs instead of traditional NSAIDs (tNSAIDs. Coxibs spare in part the endogenous gastroprotective mechanisms. Another reliable choice to improve the GI safety is the comedication of proton pump inhibitors (PPIs to suppress gastric acid. A fixed NSAID/PPI combination ensures expected protective effects by improving patients’ PPI adherence and physicians’ PPI prescription persistence. A fixed combination of enteric-coated naproxen and immediate-release esomeprazole has just been approved by the US Food and Drug Administration. PPI combinations with aspirin, other tNSAIDs, and coxibs are desirable. Patients in all risk groups, even patients at low risk of GI adverse events, benefit from concomitant protective measures. Moreover, the literature suggests that NSAID/PPI combinations are cost effective, including for patients in low-GI-risk groups. Pricing of fixed NSAID/PPI combinations will play a pivotal role for their broad acceptance in the future.Keywords: PPI, NSAID, fixed combination, gastrointestinal, adverse events, prevention

The the associated kaon-hyperon photoproduction is studied at the particle accelerator ELSA. The data were token with the combined photon spectrometers Crystal Barrel and TAPS and a linearly polarized photon beam with photon energies up to 2.9 GeV. This arrangement covers a spatial angle of about 98% and was therefore well suited to measure neutral decay channels over a large angular range. By this it is possible to determine for the reaction {gamma}p{yields}{sigma}{sup +}K{sub s}{sup 0}{yields}(p{pi}{sup 0})({pi}{sup 0}{pi}{sup 0}){yields}p6{gamma} the differential cross section, the recoil polarization P and the photon asymmetry {sigma}. The photon beam must have at last a polarization degree of 15% and its photons an energy of at least 1047 MeV. In order to improve the resolution, a kinematical fit was performed, the confidence level of which must at least amount to 0.1. Then the {sigma}{sup +}- and K{sub s}{sup 0} peaks were identified in the p{pi}{sup 0} respectively {pi}{sup 0}{pi}{sup 0} mass spectra and the background described by Monte-Carlo simulations. Because nearly the whole angular range could be measured and the acceptance for this reaction is flat over the angular range, the total cross section can be directly extracted from the data. The weak decay of the hyperon leads to a counting-rate asymmetry, from which the recoil polarization of the hyperon can be determined. From the azimutal angular distribution of the {sigma}{sup +} and K{sub s}{sup 0} particles the photon asymmetry can be extracted.

Proton pump inhibitors (PPIs) are the most effective agents available for reducing acid secretion. They are used for medical treatment of various acid-related disorders. PPIs are used extensively and for extended periods of time in gastroesophageal reflux disease (GERD). A troublesome issue regarding maintenance therapy has been the propensity of PPI-treated patients to develop chronic atrophic gastritis while on therapy that could theoretically lead to an increased incidence of gastric cancer. In addition, animal studies have raised concern for development of enterochromaffin-like cell hyperplasia and carcinoid tumors in the stomachs of mice receiving high dose PPIs. Current literature does not provide a clear-cut conclusion on the subject and the reports are sometimes contradictory. Therefore, this study is a systematic review of the available literature to address the safety of long-term PPI use and its relation to the development of malignant/premalignant gastric lesions. A literature search of biomedical databases was performed. The reference lists of retrieved articles were reviewed to further identify relevant trials. We hand-searched the abstracts of the American Digestive Disease Week (DDW) and the United European Gastroenterology Week (UEGW) from 1995 to 2013. Only randomized clinical trials (RCTs) that used PPIs as the primary treatment for at least six month versus no treatment, placebo, antacid or anti-reflux surgery (ARS) were included. Two reviewers independently extracted the data. Discrepancies in the interpretation were resolved by consensus. All analyses of outcomes were based on the intention-to-treat principle. We performed statistical analysis using Review Manager software. The effect measure of choice was relative risk (RR) for dichotomous data. Six RCTs with a total of 785 patients met the inclusion criteria. Two multicenter RCTs compared Esomeprazole with placebo. One RCT compared omeprazole with ARS. Two RCTs compared omeprazole with

The analysis of B{sup {+-}} {yields} pi{sup {+-}}{pi}{sup 0} and B{sup {+-}} {yields} K{sup {+-}}{pi}{sup 0} modes has been done with a sample of 227 millions of B pairs corresponding to 205 fb{sup -1} of data collected between october 1999 and july 2004 with the BABAR detector. The branching ratios and CP asymmetries obtained are: Br({pi}{pi}{sup 0}) = (5.57 {+-} 0.60 {+-} 0.33)*10{sup -6}; Br(K{pi}{sup 0}) (11.50 {+-} 0.65 {+-} 0.57)*10{sup -6}; A({pi}{pi}{sup 0}) = (-0.007 {+-} 0.104 {+-} 0.023); and A(K{pi}{sup 0}) = (0.066 {+-} 0.055 {+-} 0.010). The constraints on the angle alpha of the unitarity triangle have been derived from the isospin analysis of B {yields} {pi}{pi} modes. The isospin symmetry has also been used to relate B {yields} K{pi} modes in order to constraint the CKM matrix. More significant constraints have been obtained with the SU(3) symmetry for B, Bs {yields} {pi}{pi}/ K{pi}/ KK modes. They are in good agreement with the Standard CKM fit. It has been shown that such an analysis will be competitive with the Standard CKM fit in the future and will allow to determine SU(3) breaking or New Physics parameters from data. (author)

Empirical parameterization of the $K^{\\pm} \\to \\pi^{\\pm}\\pi^{0}\\pi^{0}$ decay Dalitz plot

2010-01-01

As first observed by the NA48/2 experiment at the CERN SPS, the $\\pi^{0}\\pi^{0}$ invariant mass ($M_{00}$) distribution from $K^{\\pm} \\rightarrow \\pi^{\\pm}\\pi^{0}\\pi^{0}$ decay shows a cusp-like anomaly at $M_{00}=2m_{+}$, where $m_{+}$ is the charged pion mass. An analysis to extract the $\\pi\\pi$ scattering lengths in the isospin $I=0$ and $I=2$ states, $a_{0}$ and $a_{2}$, respectively, has been recently reported. In the present work the Dalitz plot of this decay is fitted to a new empirical parameterization suitable for practical purposes, such as Monte Carlo simulations of $K^{\\pm} \\rightarrow \\pi^{\\pm}\\pi^{0}\\pi^{0}$ decays.

Momordica charantia fruit is a widely used traditional medicinal herb as, anti-diabetic, anti-HIV, anti-ulcer, anti-inflammatory, anti-leukemic, anti-microbial, and anti-tumor. The present study is undertaken to investigate the possible mode of action of fruit extracts derived from Momordica charantia (MC) and study its pharmacological effects for controlling diabetic mellitus. Effects of aqueous and chloroform extracts of Momordica charantia fruit on glucose uptake and up-regulation of glucose transporter (Glut-4), peroxisome proliferator activator receptor gamma (PPAR gamma) and phosphatidylinositol-3 kinase (PI3K), were investigated to show its efficacy as a hypoglycaemic agent. Dose dependent glucose uptake assay was performed on L6 myotubes using 2-deoxy-D-[1-(3)H] glucose. Up-regulatory effects of the extracts on the mRNA expression level of Glut-4, PPAR gamma and PI3K have been studied. The association of Momordica charantia with the aqueous and chloroform extracts of Momordica charantia fruit at 6 microg/ml has shown significant up-regulatory effect, respectively, by 3.6-, 2.8- and 3.8-fold on the battery of targets Glut-4, PPAR gamma and PI3K involved in glucose transport. The up-regulation of glucose uptake was comparable with insulin and rosiglitazone which was approximately 2-fold over the control. Moreover, the inhibitory effect of the cyclohexamide on Momordica charantia fruit extract mediated glucose uptake suggested the requirement of new protein synthesis for the enhanced glucose uptake. This study demonstrated the significance of Glut-4, PPAR gamma and PI3K up-regulation by Momordica charantia in augmenting the glucose uptake and homeostasis.

Die Behandlung von Psoriasis-Patienten mit einer Kombination aus Fumarsäureestern (FSE, Fumaderm ® ) und Phototherapie (UV) ist verbreitet, wurde aber im Rahmen von Studien wenig untersucht. Bisher liegen lediglich Daten aus einer kleinen Pilotstudie vor. Intention dieser Studie war, eine FSE/UV-Kombinationsbehandlung an einem größeren Patientenkollektiv mit mittelschwerer bis schwerer Psoriasis zu untersuchen. In dieser prospektiven, multizentrischen, nichtinterventionellen Studie wurden Daten von Patienten mit FSE/UV-Kombinationstherapie hinsichtlich der Wirksamkeit (PGA' PASI, DLQI, EQ-5D), Sicherheit und Dosierung über einen Zeitraum von zwölf Monaten erfasst und mit Daten einer retrospektiven Studie mit FSE-Monotherapie verglichen. Es wurden Daten von 363 Patienten ausgewertet. Unter der Kombinationstherapie verbesserten sich alle Wirksamkeitsparameter deutlich. Im Vergleich zur Monotherapie mit FSE konnte durch die Kombination mit UV ein schnellerer Wirkeintritt erzielt werden, wobei nach zwölf Monaten kein Unterschied in der Wirksamkeit bestand. Die Dauer und Art der Phototherapie zeigte keinen Einfluss auf die Wirksamkeitsparameter. Allgemein wurde die Kombinationstherapie gut vertragen. Unerwünschte Ereignisse wurden bei 7 % der Patienten berichtet. Die FSE/UV Kombinationstherapie zeigt eine gute Wirksamkeit und Verträglichkeit und kann zu einem schnelleren Wirkeintritt führen. Eine Kombinationstherapie erscheint vor allem in den ersten drei Monaten der FSE Behandlung sinnvoll. © 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Highly active microbial phosphoantigen induces rapid yet sustained MEK/Erk- and PI-3K/Akt-mediated signal transduction in anti-tumor human gammadelta T-cells.

Directory of Open Access Journals (Sweden)

Daniel V Correia

Full Text Available BACKGROUND: The unique responsiveness of Vgamma9Vdelta2 T-cells, the major gammadelta subset of human peripheral blood, to non-peptidic prenyl pyrophosphate antigens constitutes the basis of current gammadelta T-cell-based cancer immunotherapy strategies. However, the molecular mechanisms responsible for phosphoantigen-mediated activation of human gammadelta T-cells remain unclear. In particular, previous reports have described a very slow kinetics of activation of T-cell receptor (TCR-associated signal transduction pathways by isopentenyl pyrophosphate and bromohydrin pyrophosphate, seemingly incompatible with direct binding of these antigens to the Vgamma9Vdelta2 TCR. Here we have studied the most potent natural phosphoantigen yet identified, (E-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMB-PP, produced by Eubacteria and Protozoa, and examined its gammadelta T-cell activation and anti-tumor properties. METHODOLOGY/PRINCIPAL FINDINGS: We have performed a comparative study between HMB-PP and the anti-CD3epsilon monoclonal antibody OKT3, used as a reference inducer of bona fide TCR signaling, and followed multiple cellular and molecular gammadelta T-cell activation events. We show that HMB-PP activates MEK/Erk and PI-3K/Akt pathways as rapidly as OKT3, and induces an almost identical transcriptional profile in Vgamma9(+ T-cells. Moreover, MEK/Erk and PI-3K/Akt activities are indispensable for the cellular effects of HMB-PP, including gammadelta T-cell activation, proliferation and anti-tumor cytotoxicity, which are also abolished upon antibody blockade of the Vgamma9(+ TCR Surprisingly, HMB-PP treatment does not induce down-modulation of surface TCR levels, and thereby sustains gammadelta T-cell activation upon re-stimulation. This ultimately translates in potent human gammadelta T-cell anti-tumor function both in vitro and in vivo upon transplantation of human leukemia cells into lymphopenic mice, CONCLUSIONS/SIGNIFICANCE: The development of

The observation of hydrogen-like $\\pi K$ atoms, consisting of $\\pi^- K^+$ or $\\pi^+ K^-$ mesons, is presented. The atoms have been produced by 24 GeV/$c$ protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionisation) of $\\pi K$ atoms in the same targets yields characteristic $\\pi K$ pairs, called ``atomic pairs'', with small relative momenta in the pair centre-of-mass system. The upgraded DIRAC experiment has observed $349\\pm62$ such atomic $\\pi K$ pairs, corresponding to a signal of 5.6 standard deviations.

The time-dependence of the decay rate of initially pure K/sup 0/ into the final state ( pi /sup +/ pi /sup -/ pi /sup 0/) has been studied in search for the decay K/sup 0//sub S/ to pi /sup +/ pi /sup -/ pi /sup 0/. No evidence is found in a sample of 384 observed events. The ratio of the CP-violating K/sup 0//sub S/ amplitude and the K/sup 0 //sub L/ amplitude is eta /sub +-0/=(0.13(+0.17-0.20))+i(0.17 (+0.27-0.26)); the ratio of the CP-conserving K/sup 0//sub S/ amplitude and K/sup 0//sub L/ amplitude is mod rho mod <0.4. The energy dependence of the K/sup 0/ to pi /sup +/ pi /sup -/ pi /sup 0/ matrix element is found to be a/sub +-0/=-0.31+or-0.03. (12 refs).

Graphical abstract: A novel tube-in-tube nanostructured PPy/MnO{sub 2}/CNTs composite have been successfully fabricated. Its inner tubules are CNTs and the outer tubules are template-synthesized PPy. Most MnO{sub 2} nanoparticles are sandwiched between the inner and outer wall, some relatively large particles are also latched onto the outside wall of the PPy tube. The composite yields a good electrochemical reversibility through 1000 cycles’ cyclic voltammogram (CV) test and galvanostatic charge–discharge experiments at different current densities. Display Omitted Highlights: ► We fabricate a ternary organic–inorganic complex of PPy/MnO{sub 2}/CNTs composite. ► We characterize its morphological structures and properties by several techniques. ► The composite possesses the typical tube-in-tube nanostructures. ► Most MnO{sub 2} nanoparticles are sandwiched between the inner CNTs and outer PPy wall. ► The composite has good electrochemical reversibility for supercapacitor. -- Abstract: Ternary organic–inorganic complex of polypyrrole/manganese dioxide/carbon nanotubes (PPy/MnO{sub 2}/CNTs) composite was prepared by in situ chemical oxidation polymerization of pyrrole in the host of inorganic matrix of MnO{sub 2} and CNTs, using complex of methyl orange (MO)/FeCl{sub 3} was used as a reactive self-degraded soft-template. The morphological structures of the composite were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopic (HRTEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD), respectively. All the results indicate that the PPy/MnO{sub 2}/CNTs composite possesses the typical tube-in-tube nanostructures: the inner tubules are CNTs and the outer tubules are template-synthesized PPy. MnO{sub 2} nanoparticles may either sandwich the space between the inner and outer tubules or directly latch onto the wall of the PPy tubes. The composite

The data on the pi- p --> M0 n, with M0 = pi0 pi0 pi0 or pi0 pi0 eta obtained in the GAMS experiment may be useful to study the sigma(400--700) and a_1^chi (1000), which can be taken as chiral partners of pi and rho, respectively. A preliminary analysis for 3pi0 invariant mass spectra gives a support for the assumed a_1^chi with a mass of 930 MeV and Gamma = 170 MeV.

{pi}{pi}-correlations in hot and dense matter; {pi}{pi}-Korrelationen in heisser und dichter Materie

Energy Technology Data Exchange (ETDEWEB)

Properties of the {pi}{pi}-interactions in hot and dense matter are studied within a nonperturbative and symmetry conserving approach. The pion and its chiral partner, the {sigma}-meson, are described within the linear {sigma} model and special attention is given to the conservation of the underlying chiral symmetry. The first part deals with the properties of pion and {sigma} in the vacuum, the further being the ''Goldstone''-boson of the theory, while the latter is a broad resonance. The results in the vacuum are tested against experimental results like {pi}{pi}-phase shifts as well as the mass and the width of the {sigma}-meson. Besides the propagator of the {sigma}-meson, the preservation of the chiral symmetry is explicitly examined and chiral Ward identities for the n-point functions of the theory are fulfilled. Furthermore the {pi}{pi}-scattering matrix is calculated and shown to be consistent with predictions from chiral perturbation theory. In the second part of this work the model is extended to finite temperature with special emphasis on the chiral phase transition. The transition temperature and the critical exponent {beta} are determined, and the influence of the temperature on the propagator of the s-meson as well as on the {pi}{pi}-scattering matrix is examined. The third part deals with the properties of pion and {sigma} in dense matter. Additional couplings like the ones to particle-hole excitations and short range repulsion have to be included to ensure stability at nuclear matter density. At zero three momentum one observes a strong downward shift of the {sigma}-mass accompanied by an accumulation of strength near the two-pion threshhold in the spectral function. Taking into account a finite three momentum for the {pi}{pi}-pair, respectively the {sigma}-meson, one observes a weakening of the aforementioned effect. Having thus developed a model for the {pi}{pi}-interaction at finite temperature and density, we try to describe

Recently, we have seen interesting progress in the exploration of CP violation in B^0_d -> pi^+ pi^-: the measurements of mixing-induced CP violation by the BaBar and Belle collaborations are now in good agreement with each other, whereas the picture of direct CP violation is still unclear. Using the branching ratio and direct CP asymmetry of B^0_d -> pi^- K^+, this situation can be clarified. We predict A_CP^dir(B_d -> pi^+ pi^-) = -0.24+-0.04, which favours the BaBar result, and extract gamma=(70.0^{+3.8}_{-4.3})deg, which agrees with the unitarity triangle fits. Extending our analysis to other B -> pi K modes and B^0_s -> K^+ K^- with the help of the SU(3) flavour symmetry and plausible dynamical assumptions, we find that all observables with colour-suppressed electroweak penguin contributions are measured in excellent agreement with the Standard Model. As far as the ratios R_{c,n} of the charged and neutral B -> pi K branching ratios are concerned, which are sizeably affected by electroweak penguin contri...

Three-dimensional (3D α-Fe2O3/polypyrrole (PPy nanocomposite for effective electromagnetic absorption

Directory of Open Access Journals (Sweden)

Full Text Available The lightweight and 3-dimensional reticulated α-Fe2O3/PPy hybrids were successfully fabricated via a facile one-pot polyreaction. The measured complex permittivity and microwave attenuation performance suggest that the dielectric properties of PPy can be regulated by the mass ratio of added α-Fe2O3. The two dielectric resonance peaks of complex permittivity can be ascribed to the interface capacitor-like structure. An equivalent circuit model was established to explain the nonlinear resonance behavior of the α-Fe2O3/PPy wax composites. The addition of α-Fe2O3 properly tuned the dielectric constant to endow the composites with highly efficient microwave absorption. The minimum reflection loss of α-Fe2O3/PPy wax composites were enhanced to nearly −29dB with an effective bandwidth (RL≤ − 10dB up to 5.0GHz. The numerical method was proposed to calculate the optimum thickness for minimum RL at expected frequency by detailed investigation on the transmission formula. Moreover, the required thickness for optimum absorption efficiency at expected frequency can be obtained directly.

Patients with typical reflux symptoms (heartburn/regurgitation) persisting despite proton pump inhibitor (PPI) therapy are not uncommon. Impedance-pH monitoring detects gastroesophageal reflux at all pH levels and may establish if ongoing symptoms on PPI therapy are associated with acid/nonacid reflux. Laparoscopic fundoplication is a therapeutic option in such patients but reflux parameters on PPI therapy and after intervention and their relationship with symptom persistence/remission have been scarcely studied. The aim of this study was to assess reflux parameters and their relationship with symptoms before and after laparoscopic fundoplication, on and off PPI therapy, respectively, in patients with PPI-unresponsive heartburn/regurgitation and with a positive symptom-reflux association and/or abnormal reflux parameters detected on PPI therapy. Impedance-pH monitoring was performed on high-dose PPI therapy and 3 months after laparoscopic fundoplication, off PPI therapy, in 40 patients with PPI-unresponsive heartburn/regurgitation. Symptoms were scored by a validated questionnaire. Esophageal acid exposure time as well as the number of total and proximal reflux events and of acid and weakly acidic refluxes decreased significantly after surgery: normal values were found in 100, 77, 95, 92 and 65% of cases, respectively. Weakly alkaline refluxes increased significantly postoperatively but neither before nor after intervention were associated with symptoms. All patients reported total/subtotal remission of heartburn/regurgitation 3 months after surgery. Laparoscopic fundoplication improves acid and weakly acidic reflux parameters when compared with PPI therapy. This improvement justifies the very high post-surgical symptom remission rate that we observed. Prolonged follow-up is warranted but our findings strongly support the surgical option in PPI failures.

Polarized antiquark flavor asymmetry DELTA anti u(x)-DELTA anti d(x) and the pion cloud

The flavor asymmetry of the unpolarized antiquark distributions in the proton, anti u(x)- anti d(x)0. Using a simple chiral linear sigma model as an example, we demonstrate that in the meson cloud picture a large positive DELTA anti u(x)-DELTA anti d(x) can be obtained from pi-sigma interference contributions. This calls into question previous estimates based on rho-meson contributions alone, and indicates how the results of the meson cloud picture may be reconciled with those of quark-based models.

Amplitude models are constructed to describe the resonance structure of ${D^{0}\\to K^{-}\\pi^{+}\\pi^{+}\\pi^{-}}$ and ${D^{0} \\to K^{+}\\pi^{-}\\pi^{-}\\pi^{+}}$ decays using $pp$ collision data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb experiment, corresponding to an integrated luminosity of $3.0\\mathrm{fb}^{-1}$. The largest contributions to both decay amplitudes are found to come from axial resonances, with decay modes $D^{0} \\to a_1(1260)^{+} K^{-}$ and $D^{0} \\to K_1(1270/1400)^{+} \\pi^{-}$ being prominent in ${D^{0}\\to K^{-}\\pi^{+}\\pi^{+}\\pi^{-}}$ and $D^{0}\\to K^{+}\\pi^{-}\\pi^{-}\\pi^{+}$, respectively. Precise measurements of the lineshape parameters and couplings of the $a_1(1260)^{+}$, $K_1(1270)^{-}$ and $K(1460)^{-}$ resonances are made, and a quasi model-independent study of the $K(1460)^{-}$ resonance is performed.

Radiative corrections to the charged pion-pair production process {pi}{sup -}{gamma} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup -} at low energies

We calculate the one-photon loop radiative corrections to the charged pion-pair production process {pi}{sup -}{gamma} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup -}. In the low-energy region this reaction is governed by the chiral pion-pion interaction. The pertinent set of 42 irreducible photon-loop diagrams is calculated by using the package FeynCalc. Electromagnetic counterterms with two independent low-energy constants k{sub 1} and k{sub 2} are included in order to remove the ultraviolet divergences generated by the photon loops. Infrared finiteness of the virtual radiative corrections is achieved by including soft photon radiation below an energy cut-off {Lambda}. The purely electromagnetic interaction of the charged pions mediated by one-photon exchange is also taken into account. The radiative corrections to the total cross section (in the isospin limit) vary between +10% close to threshold and about -1% at a center-of-mass energy of 7m{sub {pi}}. The largest contribution comes from the simple one-photon exchange. Radiative corrections to the {pi}{sup +}{pi}{sup -} and {pi}{sup -}{pi}{sup -} mass spectra are studied as well. The Coulomb singularity of the final-state interaction produces a kink in the dipion mass spectra. The virtual radiative corrections to elastic {pi}{sup -}{pi}{sup -} scattering are derived additionally. (orig.)

With prevalences ranging from 0.26 to 0.8 permille of all live births tetralogy of Fallot (TOF) is the most common congenital heart disease with primary cyanosis. Due to improvements in surgical techniques, nearly all patients can nowadays expect to reach adulthood. After surgical repair, pulmonary regurgitation (PR) occurs in almost every child and is an important contributing factor in long-term morbidity and mortality. Cardiac magnetic resonance imaging is well established for functional assessment and flow measurements and is an ideal tool for serial post-surgical follow-up examinations, as it is non-invasive and does not expose patients to ionizing radiation. The timing of pulmonary valve replacement is crucial as right ventricular (RV) volumes have only proven to normalize when preoperative end-diastolic volumes are <170 ml/m{sup 2} and end-systolic volumes are <85 ml/m{sup 2}. After surgical repair up to 15% of patients have residual or recurrent pulmonary artery stenosis. Distal pulmonary branch stenosis can aggravate PR and lead to right heart failure due to combined pressure and volume overload. Therefore, it has to be diagnosed in time and treated by angioplasty with or without stenting. (orig.)

MnO 2 @PPy core-shell micromaterials are prepared by chemical polymerization of pyrrole on the MnO 2 surface. The polypyrrole (PPy) is formed as a homogeneous organic shell on the MnO 2 surface. The thickness of PPy shell can be adjusted by the usage of pyrrole. The analysis of SEM, FT-IR, X-ray photoelectron spectroscopy (XPS), thermo-gravimetric analysis (TGA), and XRD are used to confirm the formation of PPy shell. Galvanostatic cell cycling and electrochemical impedance spectroscopy (EIS) are used to evaluate the electrochemical performance as anode for lithium-ion batteries. The results show that after formation of MnO 2 @PPy core-shell micromaterials, the cyclic performance as anode for lithium-ion batteries is improved. Fifty microliters of PPy-coated caddice-clew-like MnO 2 has the best cyclic performances as has 620 mAh g -1 discharge specific capacities after 300 cycles. As a comparison, the discharge specific capacity of bare MnO 2 materials falls to below 200 mAh g -1 after 10 cycles. The improved lithium-storage cyclic stability of the MnO 2 @PPy samples attributes to the core-shell hybrid structure which can buffer the structural expansion and contraction of MnO 2 caused by the repeated embedding and disengagement of Li ions and can prevent the pulverization of MnO 2 . This experiment provides an effective way to mitigate the problem of capacity fading of the transition metal oxide materials as anode materials for (lithium-ion batteries) LIBs.

Editorial 3/2015: Handeln mit Symbolen

Full Text Available Die paradigmatische Unterscheidung zwischen Sozial- und Kulturwissenschaften, die spätestens seit den 1980er Jahren eingehend diskutiert wurde, lässt sich anhand des Bereichs des Symbolischen auf den Punkt bringen: Ist das Symbolische nur ein Effekt von sozialen, ökonomischen oder medialen Strukturen einer gegebenen Gesellschaft oder reproduzieren sich Strukturen nur durch die symbolischen Handlungen der AkteurInnen innerhalb einer gegebenen Kultur? So hatte etwa der klassische "harte" Strukturalismus bei Claude Lévi-Strauss, Jacques Lacan und dem frühen Michel Foucault symbolische Ordnungen (und d. i. hier die Sprache als eine unbewusst determinierende Voraussetzung von menschlicher Interaktion begriffen, woraufhin mit dem Post- bzw. Neostrukturalismus die Rückkehr der individuellen Äußerung, der parole, des speech acts (und d. i. hier das Sprechen, also der symbolischen Handlung in den Mittelpunkt rückte. Medienpädagogisch ist diese Unterscheidung gerade dann von Interesse, wenn es darum geht, wie Lehrende und Lernende sich zueinander verhalten, interagieren und dabei eben mit Symbolen handeln. Insofern ist es bemerkenswert, dass – fast parallel zu Foucaults Unterscheidung von diskursiven und nicht-diskursiven Praktiken – auch Dieter Baacke 1973 von diskursiven und nicht-diskursiven Symbolen gesprochen hat. Denn – wie auch im Rahmen des "Symbolischen Interaktionismus" von George Herbert Mead argumentiert wurde – können Symbole nur im Rahmen einer gegebenen Diskursökonomie von AkteurInnen diskursiv ausgetauscht werden und konstituieren dabei Erfahrungen bzw. Wahrnehmungen und somit auch die soziale bzw. kulturelle Wirklichkeit. Insofern ist die Frage nach dem Symbolischen immer auch eine Frage nach den Möglichkeiten der Handlungstheorie (im Sinne Jürgen Habermas’ bzw. der Praxeologie (im Sinne Pierre Bourdieus.

This study was designed in order to investigate the effects between rehabilitation training on the apoptosis of nerve cells and the recovery of neural and motor functions of rats with ischemic stroke by way of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) and nuclear factor E2-related factor 2/antioxidant responsive element (Nrf2/ARE) signaling pathways. In total, 110 healthy adult male Sprague-Dawley (SD) rats were selected in order to take part in this study. Ninety SD rats were used in order to establish the middle cerebral artery occlusion (MCAO), among which 80 rats were randomly assigned as part of the natural recovery, natural recovery+Rp-PI3K (the rats injected with PI3K/Akt inhibitor LY294002), rehabilitation training, and rehabilitation training+Rp-PI3K groups. Meanwhile, 20 rats were selected as part of the sham operation group. The neural and motor functions of these rats were evaluated using a balance beam test and the Bederson score. The mRNA expressions of PI3K, Akt, Nrf2 and HO-1 were measured using an RT-qPCR. The protein expressions of PI3K, p-PI3K, Akt, p-Akt, Nrf2 and HO-1 were also detected by using western blotting and the immunohistochemistry process. The cell cycle and cell apoptosis were detected by using a flow cytometry and TUNEL assay. The sham operation group exhibited lower neural and motor function scores than other groups. At the 7, 14, and 21 d marks of this study, the neural and motor function scores were increased in the natural recovery, natural recovery+Rp-PI3K, and rehabilitation training+Rp-PI3K groups in comparison with the rehabilitation training group but found to be decreased in the natural recovery group in comparison with the natural recovery+Rp-PI3K group. In comparison with the sham operation group, expressions of PI3K, Nrf2 and HO-1, and proportions of p-PI3K/PI3K and p-Akt/Akt were all higher in the natural recovery, rehabilitation training, and rehabilitation training+Rp-PI3K groups.

The Arabidopsis ppi1 Mutant Is Specifically Defective in the Expression, Chloroplast Import, and Accumulation of Photosynthetic ProteinsW⃞

The import of nucleus-encoded proteins into chloroplasts is mediated by translocon complexes in the envelope membranes. A component of the translocon in the outer envelope membrane, Toc34, is encoded in Arabidopsis by two homologous genes, atTOC33 and atTOC34. Whereas atTOC34 displays relatively uniform expression throughout development, atTOC33 is strongly upregulated in rapidly growing, photosynthetic tissues. To understand the reason for the existence of these two related genes, we characterized the atTOC33 knockout mutant ppi1. Immunoblotting and proteomics revealed that components of the photosynthetic apparatus are deficient in ppi1 chloroplasts and that nonphotosynthetic chloroplast proteins are unchanged or enriched slightly. Furthermore, DNA array analysis of 3292 transcripts revealed that photosynthetic genes are moderately, but specifically, downregulated in ppi1. Proteome differences in ppi1 could be correlated with protein import rates: ppi1 chloroplasts imported the ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit and 33-kD oxygen-evolving complex precursors at significantly reduced rates, but the import of a 50S ribosomal subunit precursor was largely unaffected. The ppi1 import defect occurred at the level of preprotein binding, which is consistent with a role for atToc33 during preprotein recognition. The data suggest that atToc33 is involved preferentially in the import of photosynthetic proteins and, by extension, that atToc34 is involved in the import of nonphotosynthetic chloroplast proteins.

The production of long-lived negative secondaries, including [pi][sup -], K[sup -], antiprotons (anti p) and antideuterons (anti d) at 0deg in Si+Au, Si+Cu, and Si+Al collisions at the BNL-AGS has been measured using a double-bend, double-focussing spectrometer. The anti p rapidity spectra from all three targets are well fit by Gaussians centered (anti y = 1.7 - 1.8) at mid-rapidity, and are consistent with production in nucleon-nucleon first collisions. The anti d/anti p[sup 2] ratio in Si+Al collisions is lower by a factor of 10 than that seen in p+p and p+A collisions. (orig.).

Localization of Piwi and piRNA has been reported mostly in nucleus and cytoplasm of higher eukaryotes germ-line cells, where it is believed that known piRNA sequences are located in repeat regions of nuclear genome in germ-line cells. However, localization of PIWI and piRNA in mammalian somatic cell mitochondria yet remains largely unknown. We identified 29 piRNA sequence alignments from various regions of the human mitochondrial genome. Twelve out 29 piRNA sequences matched stem-loop fragment sequences of seven distinct tRNAs. We observed their actual expression in mitochondria subcellular fractions by inspecting mitochondrial-specific small RNA-Seq datasets. Of interest, the majority of the 29 piRNAs overlapped with multiple longer transcripts (expressed sequence tags) that are unique to the human mitochondrial genome. The presence of mature piRNAs in mitochondria was detected by qRT-PCR of mitochondrial subcellular RNAs. Further validation showed detection of Piwi by colocalization using anti-Piwil1 and mitochondria organelle-specific protein antibodies

The K_L -> pi+pi-e+e- and K_S -> pi+pi-e+e- decay modes have been studied in detail using the NA48 detector at CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 K_L -> pi+pi-e+e- candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement BR(K_L -> pi+pi-e+e-)=(3.08+-0.20)x10^-7. The distribution of events in the sin\\phicos\\phi variable, where \\phi is the angle between the pi+pi- and the e+e- decay planes in the kaon centre of mass, is found to exhibit a large CP-violating asymmetry with the value A_\\phi(14.2+-3.6)%. For the K_S -> pi+pi-e+e- decay channel, 621 candidates have been identified in the 1999 data sample with an estimated background contribution of 0.7 event. The corresponding branching ratio has been determined to be BR(K_S -> pi+pi-e+e-)=(4.71+-0.32)x10^-5. The combined value of this measurement with the published 1998 result id BR(K_S -> pi+pi-e+e-)=4.69+-0.30)x10^-5. No asymmetry is observed ...

Wund-D.A.CH. ist der Dachverband deutschsprachiger Fachgesellschaften, die sich mit den Thematiken der Wundbehandlung beschäftigen. Experten verschiedener Fachgesellschaften aus Deutschland, Österreich und der Schweiz haben nun einen aktuellen Konsens der Kompressionstherapie für Patienten mit Ulcus cruris venosum erstellt. In Europa ist das Ulcus cruris venosum eine der häufigsten Ursachen für chronische Wunden. Neben der konservativen und interventionellen Wund- und Venentherapie, ist die Kompressionstherapie die Basis der Behandlungsstrategien. Die Kompressionstherapie kann heute mit sehr unterschiedlichen Materialien und Systemen durchgeführt werden. Während in der Entstauungsphase insbesondere Verbände mit Kurzzugbinden oder Mehrkomponentensysteme zur Anwendung kommen, sind es anschließend überwiegend Ulkus-Strumpfsysteme. Eine weitere, bislang wenig verbreitete Alternative sind adaptive Kompressionsbandagen. Insbesondere für die Rezidivprophylaxe werden medizinische Kompressionsstrümpfe empfohlen. Durch die Vielzahl der heute zur Verfügung stehenden Behandlungsoptionen, kann für nahezu alle Patienten ein Konzept entwickelt werden, dass sich an den individuellen Bedürfnissen und Fähigkeiten orientiert und daher auch akzeptiert und durchgeführt wird. Die Kompressionstherapie ist für die Behandlung von Patienten mit Ulcus cruris venosum essentiell. In den letzten Jahren sind viele verschiedene Therapieoptionen verfügbar, die in den deutschsprachigen Ländern unterschiedlich angewendet oder durchgeführt werden. Daher soll dieser Expertenkonsens dazu beitragen, konkrete Empfehlungen für die praktische Durchführung der Kompressionstherapie von Patienten mit Ulcus cruris venosum darzustellen. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Very preliminary results are presented on the non-annihilation channel antipp→antippπ + π - at the rather low incident anti p momentum of 3.6 GeV/c. The analysis was performed using an interactive cluster analysis technique developed at CERN. This kind of analysis is similar to the well known prism-plot technique developed at MIT. (L.M.K.)

To establish if the indication for different approaches for thyroidectomy and the incision length provided by means of pre-operative assessment of gland volume and size of nodules resulted in safe and effective outcomes and in any notable aesthetic or quality-of-life impact on patients. Ninehundred eightytwo consecutive patients, undergoing total thyroidectomy, were enrolled. The thyroid volume and maximal nodule diameter were measured by means of ultrasounds. Based on ultrasounds findings, patients were divided into three groups: minimally invasive video assisted thyroidectomy (MIVAT), minimally invasive thyroidectomy (MIT) and conventional thyroidectomy (CT) groups. The data concerning the following parameters were collected: operative time, postoperative complications, postoperative pain and cosmetic results. The MIVAT group included 179 patients, MIT group included 592 patients and CT group included 211 patients. Incidence of complications did not differ significantly in each group. In MIVAT and MIT group, the perception of postoperative pain was less intense than CT group. The patients in the MIVAT (7±1.5) and MIT (8±2) groups were more satisfied with the cosmetic results than those in CT group (5±1.3) (p= MIT is a technique totally reproducible, and easily convertible to perform surgical procedures in respect of the patient, without additional complications, increased costs, and with better aesthetic results.

Einleitung: Bei etwa 5% der Patienten mit chronischem Tinnitus gehen die Ohrgeräusche mit erheblichem Leidensdruck, häufig auch mit psychiatrischen Störung einher. Da es aktuell keine wirksame Behandlung gibt, welche zu Beseitigung des chronischen Tinnitus führt, ist das Therapieziel die Reduktion der Tinnitus-Belastung. Methodik: Es wurden von 7/13 bis 12/14 308 Patienten mit chronischen Tinnitus tagesklinisch interdisziplinär behandelt. Die Tinnitus-Belastung wurde mit Tinnitus-Fragebogen...

Anti-Cancer Effect of Metabotropic Glutamate Receptor 1 Inhibition in Human Glioma U87 Cells: Involvement of PI3K/Akt/mTOR Pathway

Directory of Open Access Journals (Sweden)

Chi Zhang

Full Text Available Background: Metabotropic glutamate receptors (mGluRs are G-protein-coupled receptors that mediate neuronal excitability and synaptic plasticity in the central nervous system, and emerging evidence suggests a role of mGluRs in the biology of cancer. Previous studies showed that mGluR1 was a potential therapeutic target for the treatment of breast cancer and melanoma, but its role in human glioma has not been determined. Methods: In the present study, we investigated the effects of mGluR1 inhibition in human glioma U87 cells using specific targeted small interfering RNA (siRNA or selective antagonists Riluzole and BAY36-7620. The anti-cancer effects of mGluR1 inhibition were measured by cell viability, lactate dehydrogenase (LDH release, TUNEL staining, cell cycle assay, cell invasion and migration assays in vitro, and also examined in a U87 xenograft model in vivo. Results: Inhibition of mGluR1 significantly decreased the cell viability but increased the LDH release in a dose-dependent fashion in U87 cells. These effects were accompanied with the induction of caspase-dependent apoptosis and G0/G1 cell cycle arrest. In addition, the results of Matrigel invasion and cell tracking assays showed that inhibition of mGluR1 apparently attenuated cell invasion and migration in U87 cells. All these anti-cancer effects were ablated by the mGluR1 agonist L-quisqualic acid. The results of western blot analysis showed that mGluR1 inhibition overtly decreased the phosphorylation of PI3K, Akt, mTOR and P70S6K, indicating the mitigated activation of PI3K/Akt/mTOR pathway. Moreover, the anti-tumor activity of mGluR1 inhibition in vivo was also demonstrated in a U87 xenograft glioma model in athymic nude mice. Conclusion: The remarkable efficiency of mGluR1 inhibition to induce cell death in U87 cells may find therapeutic application for the treatment of glioma patients.

We derive the off-shell nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST) as well as anti-BRST transformations s ( a) b corresponding to the Yang-Mills gauge transformations of 3D Jackiw-Pi model by exploiting the "augmented" super-field formalism. We also show that the Curci-Ferrari restriction, which is a hallmark of any non-Abelian 1-form gauge theories, emerges naturally within this formalism and plays an instrumental role in providing the proof of absolute anticommutativity of s ( a) b .

Strong final-state interactions create a pronounced cusp in {eta}'{yields}{eta}{pi}{sup 0}{pi}{sup 0} decays. We adapt and generalize the non-relativistic effective field theory framework developed for the extraction of {pi}{pi} scattering lengths from K{yields}3{pi} decays to this case. The cusp effect is predicted to have an effect of more than 8% on the decay spectrum below the {pi}{sup +}{pi}{sup -} threshold. (orig.)

Full Text Available Electrode modification on screen printed carbon electrode (SPCE with polypyrrole (Ppy-SiO2 was done by electropolymerization. Polypyrrole (Ppy-SiO2 was used for phenol determination. The analysis of this material was done by using Scanning Electron Microscopy (SEM, cyclic voltammetry method and differential pulse voltammetry. In a cyclic voltammetry analysis, we used potential range of -1 to 1 V with Ag/AgCl comparator electrode at scan rate of 100 mV/sec, while in differential pulse voltammetry method the potential range was 0 to 1 V toward Ag/AgCl, the scan rate of 50 mV/sec, the pulse rate is 0,2 V and the pulse width is 50 ms. From the analysis result with SEM, cyclic voltammetry and differential pulse voltammetry method, Polypyrrole (Ppy -SiO2 is the best material and can be used as phenol measurement.

ABSTRACT Chitin is an important cell wall component of Aspergillus fumigatus conidia, of which hundreds are inhaled on a daily basis. Previous studies have shown that chitin has both anti- and proinflammatory properties; however the exact mechanisms determining the inflammatory signature of chitin are poorly understood, especially in human immune cells. Human peripheral blood mononuclear cells were isolated from healthy volunteers and stimulated with chitin from Aspergillus fumigatus. Transcription and production of the proinflammatory cytokine interleukin-1β (IL-1β) and the anti-inflammatory cytokine IL-1 receptor antagonist (IL-1Ra) were measured from the cell culture supernatant by quantitative PCR (qPCR) or enzyme-linked immunosorbent assay (ELISA), respectively. Chitin induced an anti-inflammatory signature characterized by the production of IL-1Ra in the presence of human serum, which was abrogated in immunoglobulin-depleted serum. Fc-γ-receptor-dependent recognition and phagocytosis of IgG-opsonized chitin was identified as a novel IL-1Ra-inducing mechanism by chitin. IL-1Ra production induced by chitin was dependent on Syk kinase and phosphatidylinositol 3-kinase (PI3K) activation. In contrast, costimulation of chitin with the pattern recognition receptor (PRR) ligands lipopolysaccharide, Pam3Cys, or muramyl dipeptide, but not β-glucan, had synergistic effects on the induction of proinflammatory cytokines by human peripheral blood mononuclear cells (PBMCs). In conclusion, chitin can have both pro- and anti-inflammatory properties, depending on the presence of pathogen-associated molecular patterns and immunoglobulins, thus explaining the various inflammatory signatures reported for chitin.

Highlights: • The high-dispersed Ag modified g-C{sub 3}N{sub 4} (Ag/g-C{sub 3}N{sub 4}) was successfully synthesized in situ deposited on the surface of g-C{sub 3}N{sub 4} during calcined melamine. • The as-prepared Ppy@Ag/g-C{sub 3}N{sub 4} could remove of various organic pollutants in water. • The enhanced photocatalytic activity of Ppy@Ag/g-C{sub 3}N{sub 4} comes from π conjugated electronic structures of Ppy and Ag species as the electron transfer mediator between Ppy and g-C{sub 3}N{sub 4}. • The Ppy@Ag/g-C{sub 3}N{sub 4} sample also showed a relatively good recycling stability. - Abstract: The ternary conductive Ppy@Ag/g-C{sub 3}N{sub 4} composite photocatalysts was successfully synthesized by polymerization process and surface polymerization technique. And the as-prepared Ppy@Ag/g-C{sub 3}N{sub 4} sample exhibited the higher photocatalytic activity for various pollutant (MO, DM, TC, CIP, GFLX and EH) remove than that of pure g-C{sub 3}N{sub 4} and Ag/g-C{sub 3}N{sub 4} under visible light irradiation. It mainly originated from the Ag nanoparticles anchored between g-C{sub 3}N{sub 4} and Ppy acted as electron transfer mediator that facilitated the charge carrier separation and then expending the lifetime of the carriers. Meanwhile, the obtained Ppy@Ag/g-C{sub 3}N{sub 4} sample also showed a relatively good recycling stability which was the crucial factor for photocatalyst practical application. This work provided a new facile strategy for improving photo-degradation activity of g-C{sub 3}N{sub 4} photocatalyst.

In the present work, in situ synthesis of polypyrrole-silver-polyvinylpyrrolidone (PPy-Ag-PVP) nanohybrid using AgNO 3 as an oxidant and polyvinylpyrrolidone (PVP) as a stabilizer and surfactant is demonstrated. The obtained ternary PPy-Ag-PVP nanohybrid was characterized by UV-vis, FT-IR, XRD, Raman, TGA, SEM, and HR-TEM analysis. Further the synthesized PPy-Ag-PVP has been investigated for its selective and sensitive sensing of dopamine (DA). The PPy-Ag-PVP modified glassy carbon electrode shows a reversible electrochemical behavior with superior response for DA. The limit of detection and limit of quantification are found to be 0.0126 and 0.042 μM (S/N = 3 and 10), respectively, with remarkable sensitivity (7.26 μA mM -1 cm -2 ). The practical application of the present modified electrode has been validated by determining the concentration of DA in human urine samples of different age group.

Phosphatidylinositol 3-kinase (PI3-K)/PTEN/Akt signaling is over activated in various tumors including colon cancer. Activation of this pathway regulates multiple biological processes such as apoptosis, metabolism, cell proliferation, and cell growth that underlie the biology of a cancer cell. In the present study, the chemopreventive effects have been observed of Diclofenac, a preferential COX-2 inhibitory non-steroidal anti-inflammatory drugs, and Curcumin, a natural anti-inflammatory agent, in the early stage of colorectal carcinogenesis induced by 1,2-dimethylhydrazine dihydrochloride in rats. The tumor-promoting role of PI3-K/Akt/PTEN signal transduction pathway and its association with anti-apoptotic family of proteins are also observed. Both Diclofenac and Curcumin downregulated the PI3-K and Akt expression while promoting the apoptotic mechanism. Diclofenac and Curcumin administration significantly increased the expression of pro-apoptotic Bcl-2 family members (Bad and Bax) while decreasing the anti-apoptotic Bcl-2 protein. An up-regulation of cysteine protease family apoptosis executioner, such as caspase-3 and -9, is seen. Diclofenac and Curcumin inhibited the Bcl-2 protein by directly interacting at the active site by multiple hydrogen bonding, as also evident by negative glide score of Bcl-2. These drugs stimulated apoptosis by increasing reactive oxygen species (ROS) generation and simultaneously decreasing the mitochondrial membrane potential (ΔΨ M). Diclofenac and Curcumin showed anti-neoplastic effects by downregulating PI3-K/Akt/PTEN pathway, inducing apoptosis, increasing ROS generation, and decreasing ΔΨ M. The anti-neoplastic and apoptotic effects were found enhanced when both Diclofenac and Curcumin were administered together, rather than individually.

The systematic exploration of excited meson and baryon states was the central topic of the COmmon Muon Proton Apparatus for Structure and Spectroscopy (COMPASS) physics program in the years 2008 and 2009 at the CERN facility. Particularly states non fitting a constituent quark model were searched for, identified by their exotic quantum numbers which are forbidden by a simple q anti q scheme. A high energetic hadron-beam on a fixed target yielded in resonances decaying into a large variety of final states. The diffractive and central production mechanisms allowed for a clean exclusive selection of channels such as {pi}{sup -}p {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +}p{sub recoil}, which then were analysed with a high precision and a huge number of events. Apart from the main pion component in the negative hadron beam a small fraction of kaons of about 2.5% allowed the study of light strange resonances in the K{sup -}{pi}{sup +}{pi}{sup -} decay channel. The best measurement in this channel was quoted to be so far the measurement of the WA03 experiment at CERN. The ACCMOR-collaboration has the data recorded and analysed with an experimental set-up very similar to the COMPASS-spectrometer. COMPASS had therefore not only the ability to remeasure this channel with a significantly higher number of events and better precision to cross-check those over 30 years old results. Moreover, improved analysis methods together with new evidences from other experiments, are expected to enlighten our present picture of the hadron spectrum. Chapter 1 introduces the concept of meson spectroscopy. The formation of bound quark anti-quark systems allows to interpret our measurements in terms of coupled quantum numbers, with properties as spin, charge conjugation and parity. Particularly kaonic isospin I=(1)/(2) resonances are classified as proposed by group theory and differences to I=1 and I=0 states, formed mainly by u and d quarks and their anti-quarks, are pointed out.

Highlights: • A new photocatalyst PPy/Bi{sub 2}O{sub 2}CO{sub 3} was synthesized by a simple hydrothermal method. • The PPy/Bi{sub 2}O{sub 2}CO{sub 3} photocatalyst shows enhanced degradation activity of RhB under UV light irradiation. • A photocatalytic mechanism is proposed based on the synergistic effect of PPy and Bi{sub 2}O{sub 2}CO{sub 3}. - Abstract: Photocatalyst Bi{sub 2}O{sub 2}CO{sub 3} modified by polypyrrole (PPy) was synthesized via a facile hydrothermal method. As-prepared PPy/Bi{sub 2}O{sub 2}CO{sub 3} composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV–vis diffuse reflectance spectroscopy (DRS). Presence of PPy did not affect the crystal structure, but exerted great influence on the photocatalytic activity of Bi{sub 2}O{sub 2}CO{sub 3} and enhanced absorption band of pure Bi{sub 2}O{sub 2}CO{sub 3}. The photocatalytic activities of the PPy/Bi{sub 2}O{sub 2}CO{sub 3} samples were determined by photocatalytic degradation of Rhodamine-B (RhB) under ultra violet (UV) irradiation and 0.75 wt.% PPy/Bi{sub 2}O{sub 2}CO{sub 3} composite showed the highest photocatalytic activity. The enhanced photocatalytic performance could be attributed to the synergistic effect of PPy and Bi{sub 2}O{sub 2}CO{sub 3}. A possible photocatalytic mechanism of the PPy/Bi{sub 2}O{sub 2}CO{sub 3} photocatalysts was proposed in order to guide the further improvement of its photocatalytic performance.

Plasma levels of antibodies against phosphatidylinositol (PI), phosphatidylcholine (PC) and cardiolipin (CL) were measured by enzyme-linked immunosorbent assay (ELISA) in patients from malaria endemic area of Sudan and The Gambia. Some Sudanese adults produced IgM antibodies against all three types...... of phospholipids (PL) during an acute Plasmodium falciparum infection. The anti-PL antibody titre returned to preinfection levels in most of the donors 30 days after the disease episode. IgG titres against PI, PC and CL were low. In Gambian children with malaria, IgM antibody titres against PI and PC were...... significantly higher in those with severe malaria than in those with mild malaria. These results show that a proportion of malaria patients produce anti-PL antibodies during infection and that titres of these antibodies are associated with the severity of disease....

Discovering functional interdependence relationship in PPI networks for protein complex identification.

Protein molecules interact with each other in protein complexes to perform many vital functions, and different computational techniques have been developed to identify protein complexes in protein-protein interaction (PPI) networks. These techniques are developed to search for subgraphs of high connectivity in PPI networks under the assumption that the proteins in a protein complex are highly interconnected. While these techniques have been shown to be quite effective, it is also possible that the matching rate between the protein complexes they discover and those that are previously determined experimentally be relatively low and the "false-alarm" rate can be relatively high. This is especially the case when the assumption of proteins in protein complexes being more highly interconnected be relatively invalid. To increase the matching rate and reduce the false-alarm rate, we have developed a technique that can work effectively without having to make this assumption. The name of the technique called protein complex identification by discovering functional interdependence (PCIFI) searches for protein complexes in PPI networks by taking into consideration both the functional interdependence relationship between protein molecules and the network topology of the network. The PCIFI works in several steps. The first step is to construct a multiple-function protein network graph by labeling each vertex with one or more of the molecular functions it performs. The second step is to filter out protein interactions between protein pairs that are not functionally interdependent of each other in the statistical sense. The third step is to make use of an information-theoretic measure to determine the strength of the functional interdependence between all remaining interacting protein pairs. Finally, the last step is to try to form protein complexes based on the measure of the strength of functional interdependence and the connectivity between proteins. For performance evaluation

A search for the $D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-$ decay, where the muon pair does not originate from a resonance, is performed using proton-proton collision data corresponding to an integrated luminosity of $1.0\\mathrm{fb}^{-1}$ recorded by the LHCb experiment at a centre-of-mass energy of $7\\mathrm{TeV}$. No signal is observed and an upper limit on the relative branching fraction with respect to the resonant decay mode $D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)$, under the assumption of a phase-space model, is found to be \\begin{align} \\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-)/\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)) < 0.96\\\\ \\end{align} at the $90\\%$ confidence level. The upper limit on the absolute branching fraction is evaluated to be $\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-) < 5.5 \\, \\times 10^{-7}$ at 90% confidence level.

This paper describes our efforts to employ the Microsoft Kinect as a low cost vision control system for the MIT-Skywalker, a robotic gait rehabilitation device. The Kinect enables an alternative markerless solution to control the MIT-Skywalker and allows a more user-friendly set-up. A study involving eight healthy subjects and two stroke survivors using the MIT-Skywalker device demonstrates the advantages and challenges of this new proposed approach.

A study of $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states is performed using pp collision data, corresponding to an integrated luminosity of 1.0 $fb^{-1}$, collected at a centre-of-mass energy of 7 TeV with the LHCb detector. The $D_1(2420)^0$ resonance is observed in the $D^{*+}\\pi^-$ final state and the $D^*_2(2460)$ resonance is observed in the $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states. For both resonances, their properties and spin-parity assignments are obtained. In addition, two natural parity and two unnatural parity resonances are observed in the mass region between 2500 and 2800 MeV. Further structures in the region around 3000 MeV are observed in all the $D^{*+}\\pi^-$, $D^+\\pi^-$ and $D^0 \\pi^+$ final states.

The charmless decays $B^{\\pm} \\rightarrow K^{+}K^{-}\\pi^{\\pm}$ and $B^{\\pm} \\rightarrow \\pi^{+}\\pi^{-}\\pi^{\\pm}$ are reconstructed in a data set, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of pp collisions at a center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be $A_{CP}(B^{\\pm} \\rightarrow K^{+}K^{-}\\pi^{\\pm}) =-0.141 \\pm 0.040 (stat) \\pm 0.018 (syst) \\pm 0.007 (J/\\psi K^{\\pm})$ and $A_{CP}(B^{\\pm} \\rightarrow \\pi^{+}\\pi^{-}\\pi^{\\pm}) = 0.117 \\pm 0.021 (stat) \\pm 0.009 (syst) \\pm 0.007 (J/\\psi K^{\\pm})$, where the third uncertainty is due to the CP asymmetry of the $B^{\\pm} \\rightarrow J/\\psi K^{\\pm}$ reference mode. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.

Despite its obvious pathophysiological relevance, the clinical utility of measures of esophagogastric junction (EGJ) contractility is unsubstantiated. High-resolution manometry (HRM) may improve upon this with its inherent ability to integrate the magnitude of contractility over time and length of the EGJ. This study aimed to develop a novel HRM metric summarizing EGJ contractility and test its ability distinguish among subgroups of proton pump inhibitor non-responders (PPI-NRs). 75 normal controls and 88 PPI-NRs were studied. All underwent HRM. PPI-NRs underwent pH-impedance monitoring on PPI therapy scored in terms of acid exposure, number of reflux events, and reflux-symptom correlation and grouped as meeting all criteria, some criteria, or no criteria of abnormality. Control HRM studies were used to establish normal values for candidate EGJ contractility metrics, which were then compared in their ability to differentiate among PPI-NR subgroups. The EGJ contractile integral (EGJ-CI), a metric integrating contractility across the EGJ for three respiratory cycles, best distinguished the All Criteria PPI-NR subgroup from controls and other PPI-NR subgroups. Normal values (median, [IQR]) for this measure were 39 mmHg-cm [25-55 mmHg-cm]. The correlation between the EGJ-CI and a previously proposed metric, the lower esophageal sphincter-pressure integral, that used a fixed 10 s time frame and an atmospheric as opposed to gastric pressure reference was weak. Among HRM metrics tested, the EGJ-CI was best in distinguishing PPI-NRs meeting all criteria of abnormality on pH-impedance testing. Future prospective studies are required to explore its utility in management of broader groups of gastroesophageal reflux disease patients. © 2013 John Wiley & Sons Ltd.

The influence of KD and K anti K mesonic molecules in selected reactions; Auswirkung der im KD- und K anti K-Kanal gebildeten mesonischen Molekuele in verschiedenen Reaktionen

The attractive potential of the Juelich meson exchange model in the K anti K-channel causes formation of a scalar isoscalar molecule. We investigate this observation from different points of view. First we look at the dependence of pion production in the peripheral reaction {pi}{sup -}p {yields} {pi}{sup 0}{pi}{sup 0}n on the momentum transferred at the nucleus. Accounting for the production via {pi} and a{sub 1} emission in a consistent way, we are able to explain the momentum dependence using the Juelich model. Furthermore we investigate how a measurement of dd {yields} {alpha}K anti K close to threshold may contribute to our knowledge on K anti K interaction and the f{sub 0}(980). The Juelich model links the properties of the f{sub 0}(980) to the a{sub 0}(980). We will use this information to learn about the d anti K-interaction in pp {yields} dK anti K. The recent discovery of the D{sup *}{sub sJ}(2317) o ers a different perspective on the dynamical generation of poles, since it may be connected to the KD-threshold nearby. We construct a SU(4)-extention of the Juelich model including isospin violation. Within this extention a dynamical resonance is formed, which only may explain the D{sup *}{sub sJ}(2317) if isoscalar production is assumed. Special interest is paid to the predicted width of the D{sup *}{sub sJ}(2317) associated with a dynamical interpretation. (orig.)

The Dalitz plot analysis technique is used to study the resonant substructures of $B^- \\to D^+ \\pi^- \\pi^-$ decays in a data sample corresponding to 3.0 fb$^-1$ of $pp$ collision data recorded by the LHCb experiment during 2011 and 2012. A model-independent analysis of the angular moments demonstrates the presence of resonances with spins 1, 2 and 3 at high $D^+\\pi^-$ mass. The data are fitted with an amplitude model composed of a quasi-model-independent function to describe the $D^+\\pi^-$ S-wave together with virtual contributions from the $D^*(2007)^{0}$ and $B^{*0}$ states, and components corresponding to the $D^*_2(2460)^{0}$, $D^*_1(2680)^{0}$, $D^*_3(2760)^{0}$ and $D^*_2(3000)^{0}$ resonances. The masses and widths of these resonances are determined together with the branching fractions for their production in $B^- \\to D^+ \\pi^- \\pi^-$ decays. The $D^+\\pi^-$ S-wave has phase motion consistent with that expected due to the presence of the $D^*_0(2400)^{0}$ state. These results constitute the first obser...

Direct CP violation in B -> pi sup +pi sup -pi. Determination of alpha without discrete ambiguity

Leitner, O; Thomas, A W

2002-01-01

Direct CP violation in the hadronic decays B-bar sup 0 -> pi sup +pi sup -pi sup 0 is investigated near the peak of the rho sup 0 taking into account the effect of rho - omega mixing. Branching ratio for processes B sup+- sup , sup 0 -> rho sup+- sup , sup 0 pi sup+- sup , sup 0 and B sup - -> omega pi sup - are calculated as well. We find that the CP violation asymmetry is strongly dependent on the CKM matrix elements. For a fixed N sub c sup e sup f sup f , the CP violation asymmetry, a, has a maximum of order - 40% to - 70% for B-bar sup 0 -> rho sup 0 (omega)pi sup 0 when the invariant mass of the pi sup +pi sup - pair is in the vicinity of the omega resonance. The sensitivity of the asymmetry to N sub c sup e sup f sup f is small in that case. Moreover, we find that in the range of N sub c sup e sup f sup f which is allowed by the most recent experimental branching ratios from the BABAR, BELLE and CLEO Collaborations, the sign of sin delta is always positive. Thus, a measurement of direct CP violation in...

Decorating MOF-Derived Nanoporous Co/C in Chain-Like Polypyrrole (PPy Aerogel: A Lightweight Material with Excellent Electromagnetic Absorption

Full Text Available To clear away the harmful effects of the increment of electromagnetic pollution, high performance absorbers with appropriate impedance matching and strong attenuation capacity are strongly desired. In this study, a chain-like PPy aerogel decorated with MOF-derived nanoporous Co/C (Co/C@PPy has been successfully prepared by a self-assembled polymerization method. With a filler loading ratio of 10 wt %, the composite of Co/C@PPy could achieve a promising electromagnetic absorption performance both in intensity and bandwidth. An optimal reflection loss value of −44.76 dB is achieved, and the effective bandwidth (reflection loss lower than −10 dB is as large as 6.56 GHz. Furthermore, a composite only loaded with 5 wt % Co/C@PPy also achieves an effective bandwidth of 5.20 GHz, which is even better than numerous reported electromagnetic absorption (EA materials. The result reveals that the as-fabricated Co/C@PPy—with high absorption intensity, broad bandwidth, and light weight properties—can be utilized as a competitive absorber.

High Operating Voltage Supercapacitor Using PPy/AC Composite Electrode Based on Simple Dipping Method

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available As various wearable devices are emerging, self-generated power sources, such as piezoelectric generators, triboelectric generators, and thermoelectric generators, are of interest. To adapt self-generated power sources for application devices, a supercapacitor is necessary because of the short generation times (1–10 ms and low generated power (1–100 μW of self-generated power sources. However, to date, supercapacitors are too large to be adapted for wearable devices. There have been many efforts to reduce the size of supercapacitors by using polypyrrole (PPy for high energy supercapacitor electrodes. However, these supercapacitors have several disadvantages, such as a low operating voltage due to the use of an aqueous electrolyte, and complex manufacturing methods, such as the hydrogel and aerosol methods. In particular, the low operating voltage (~1.0 V is a significant issue because most electronic components operate above 3.0 V. In this study, we successfully demonstrated the high operating voltage (3.0 V of a supercapacitor using a PPy/activated carbon (AC composite electrode based on the chemical polymerization of the PPy by simple dipping. In addition, a twofold enhancement of its energy density was achieved compared with conventional supercapacitors using AC electrodes.

Temperature dependence of the lifetime {tau}3 and intensity I{sub 3} of the long-lived ortho-positronium (o-Ps) component was measured for two polyimides PI189 and PI304 both below and above glass-transition temperatures Tg of these polymers. First heating runs of the experiments revealed anomalous, irregular behavior of the lifetime {tau}3 in both PI in the vicinity (below) of the glass transition temperature. The effect was similar to that discussed recently for a number of PI. However, on the cooling stage of the first cycle and on the heating run of the second cycle, such irregularities disappeared. These results show that anomalous behavior of annihilation characteristics of o-Ps in our PI samples were due not to anomalous behavior of PI structure itself close to Tg point (not to a specific phase transition), but to removal of residual solvent in vicinity of Tg during the first heating cycle. Different approaches to estimations of the specific hole volume and of the holes number density N on the basis of positron annihilation data are discussed. Final estimation for PI189 gives the fractional free volume h=3.35% and N=0.44x1027m-3. The effects of positron trapping by polar-CO groups on annihilation characteristics of PI and on the obtained value of N are also considered.

The Mi-T2 training module was built based on the Sidek Module Development Model (2001). Constructivist learning theory, cognitive learning theory, i-THINK map and higher order thinking skills were the building blocks of the module development. In this study, researcher determined the validity and reliability of Mi-T2 module. The design being used in this study was descriptive study. To determine the needs of Mi-T2 module, questionnaires and literature review were used to collect data. When the need of the module was determined, the module was built and a pilot study was conducted to test the reliability of the Mi-T2 module. The pilot study was conducted at a secondary school in North Kinta, Perak. A Form Two class was selected to be the sample study through clustered random sampling. The pilot study was conducted for two months and one topic had been studied. The Mi-T2 module was evaluated by five expert panels to determine the content validity of the module. The instruments being used in the study were questionnaires about the necessity of the Mi-T2 module for guidance, questionnaires about the validity of the module and questionnaires concerning the reliability of the module. Statistical analysis was conducted to determine the validity and reliability coefficients of the Mi-T2 module. The content validity of Mi-T2 module was determined by Cohen's Kappa's (1968) agreement coefficient and the reliability of Mi-T2 module was determined by Cronbach Alpha's value scale. The content validity of Mi-T2 module was 0.89 and the Cronbach Alpha's value of Mi-T2 module was 0.911.

Cervical cancer is the second leading cause of cancer deaths in women worldwide. In recent years, the studies find that inflammation is a critical component of tumor progression, and the ideal therapeutic methods should be aimed at the inflammation reaction triggers. (1β,3β,5β,25S)-spirostan-1,3-diol1-[α-L-rhamnopyranosyl-(1 → 2)-β-D-xylopyranoside] (RCE-4) was the main active composition of Reineckia carnea (Andr.) Kunth. It significantly induced apoptosis in cervical cancer Caski cells through the mitochondrial pathway in our previous studies; however, its underlying mechanism remains poorly understood. This study aimed to further evaluate the effect of RCE-4 on human cervical cancer HeLa cells. Based on this observation, we investigated the anti-cervical cancer effect of RCE-4 by modulating phosphatidylinositol 3-kinase/protein kinase-B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway, nuclear factor-kappa B (NF-κB) activation, and inflammation-related key factors in HeLa cells. The results indicated that the HeLa cell was the most sensitive with an IC50 of 7.01 μM; RCE-4 significantly promoted the release of cellular lactate dehydrogenase (LDH); increased DNA fragmentation and apoptosis; reduced PI3K, Akt, mTOR, and NF-κBp65 phosphorylation levels; increased the Bax and cleaved poly (ADP-ribose) polymerase (PARP) protein levels; suppressed Bcl-2 protein expression; elevated the Bax/Bcl-2 expression ratio; and decreased the interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) mRNA expressions in HeLa cells in a concentration-dependent manner. These findings suggest that RCE-4 exerted beneficially anti-cervical cancer effect on HeLa cells, mainly inhibiting PI3K/Akt/mTOR signaling pathway phosphorylation and NF-κB activation, promoting HeLa cell apoptosis.

Equilibria and partitioning of complexes in the S-adenosylmethionine synthetase reaction

International Nuclear Information System (INIS)

Markham, G.D.

1987-01-01

S-adenosylmethionine synthetase (ATP: L-methionine S-adenosyltransferase) catalyzes a reaction in which the [enzyme-ATP-methionine] complex reacts to form an intermediate [enzyme-AdoMet-PPPi] complex: hydrolysis of PPPi yields an [enzyme-AdoMet-PPi-Pi] complex from which AdoMet is the last product to dissociate. Analysis of reaction mixtures which were quenched with acid during turnover of E. coli AdoMet synthetase with saturating substrates containing [α - 32 P]ATP showed that PPPi is present in an amount corresponding to 45% of the total enzyme active sites, reflecting the portion of enzyme present in an [enzyme-AdoMet-PPPi] complex. Similar experiments in which excess pyrophosphatase was included (to hydrolyze PPi as it was released from AdoMet synthetase), showed that enzyme-bound PPi is present in an amount corresponding to 22% of the total AdoMet synthetase. The enzyme not present in complexes with PPPi or PPi is probably distributed between the [enzyme-ATP-methionine] and the [enzyme-AdoMet] complexes. AdoMet synthetase forms enzyme-bound 32 PPPi from added 32 PPi and Pi; the equilibrium constant [enzyme-AdoMet-PPi-Pi]/[enzyme-AdoMet-PPPi] is 2.0, greatly displaced from the equilibrium for hydrolysis of free PPPi. Since the ratio of enzyme-bound PPi to PPPi is 0.5 during the steady state, the PPPi hydrolysis step is not at equilibrium during turnover. Formation of [ 32 P]ATP from the [enzyme-AdoMet- 32 PPPi] complex was not detected

In the first part of this experiment, we determined the total cross section for processes yielding only neutral particles, from 300 to 1600 MeV. For this, we counted the number of incident {pi}{sup -}, as defined by a counter telescope, which interact in a liquid-hydrogen target without giving charged particles in a 4{pi} counter surrounding the target. In the second part of this experiment, we have separated the reaction {pi}{sup -} p {yields} {pi}{sup 0} n and {pi}{sup -} p {yields} {pi}{sup 0} {pi}{sup 0} n between 300 and 1100 MeV, by supposing that only these two reactions was realized by placing lead absorbers between the target and 4{pi} counter and by comparing the counting rate for neutral events with and without lead. The transmission thus measured is a function of the average number of photons produced and therefore of the ratio between the two neutral channels, {pi}{sup 0} n and {pi}{sup 0} {pi}{sup 0} n. In the last section of this work, we discuss the experimental results and compare them to those obtained by other authors in the study of photoproduction and the {pi}-nucleon interaction.

Decays of baryon resonances in the second and the third resonance region into N{pi}{sup 0}{pi}{sup 0} are studied by photoproduction of two neutral pions off protons. Partial decay widths of N* and {delta}* resonances decaying into {delta}(1232){pi}, N({pi}{pi}){sub S}, N(1440)P{sub 11}{pi}, and N(1520)D{sub 13}{pi} are determined in a partial wave analysis of this data and of data from other reactions. Several partial decay widths were not known before. Interesting decay patterns are observed which are not even qualitatively reproduced by quark model calculations. In the second resonance region, decays into {delta}(1232){pi} dominate clearly. The N({pi}{pi}){sub S}-wave provides a significant contribution to the cross section, especially in the third resonance region. The P{sub 13}(1720) properties found here are at clear variance to PDG values.

The pneumo- and hepato-toxicity of 4-vinylphenol (4VP), a styrene metabolite, has been previously reported. Nevertheless, the present study reported the novel anti-angiogenic activities of 4VP which was firstly isolated from the aqueous extract of a Chinese medicinal herb Hedyotis diffusa. Our results showed that 4VP at non-toxic dose effectively suppressed migration, tube formation, adhesion to extracellular matrix proteins, as well as protein and mRNA expressions of metalloproteinase-2 of human endothelial cells (HUVEC and HMEC-1). Investigation of the signal transduction revealed that 4VP down-regulated PI3K/AKT and p38 MAPK. Besides, 4VP interfered with the phosphorylation of ERK1/2, the translocation and expression of NFkappaB. In zebrafish embryo model, the new blood vessel growth was significantly blocked by 4VP (6.25-12.5 μg/mL medium). The VEGF-induced blood vessel formation in Matrigel plugs in C57BL/6 mice was suppressed by 4VP (20-100 μg/mL matrigel). In addition, the blood vessel number and tumor size were reduced by intraperitoneal 4VP (0.2-2 mg/kg) in 4T1 breast tumor-bearing BALB/c mice, with doxorubicin as positive control. Together, the in vitro and in vivo anti-angiogenic activities of 4VP were demonstrated for the first time. These findings suggest that 4VP has great potential to be further developed as an anti-angiogenic agent.

We derive the off-shell nilpotent and absolutely anti-commuting Becchi-Rouet-Stora-Tyutin (BRST) as well as anti-BRST symmetry transformations corresponding to the non-Yang-Mills (NYM) symmetry transformations of (2+1)-dimensional Jackiw-Pi (JP) model within the framework of "augmented" superfield formalism. The Curci-Ferrari (CF) restriction, which is a hallmark of non-Abelian one-form gauge theories, does not appear in this case. One of the novel features of our present investigation is the derivation of proper (anti-)BRST symmetry transformations corresponding to the auxiliary field ρ that cannot be derived by any conventional means.

A modified Chew-Low extrapolation procedure is applied to the reaction pi /sup -/p to Delta /sup ++/ pi /sup -/ pi /sup -/ to extract the I=2 pi pi elastic cross sections from threshold to 1260 MeV. The predictions of the one-pion-exchange model are used to estimate the contributions from background processes of the type pi /sup -/p to Delta /sup 0/ rho /sup 0/. The moments of the pi /sup -/ pi /sup -/ angular distribution are also extrapolated to the pion pole and a phase shift analysis performed. The s-wave inelasticity is constrained using information on the inelastic cross section coming from six-body final states. The magnitude of the s-wave phase shift at the K/sup 0/ mass is found to be 7.2 degrees +or-1.0 degrees , increasing to 26.2 degrees +or-2.5 degrees at 1 GeV. d- and g-waves contribute above about 900 MeV, but the corresponding phase shifts are small compared with the s-wave. All three phase shifts have the same sign. (24 refs).

A series of amino-substituted triazines were developed and examined for PI3Kβ inhibition and anti-platelet function. Structural adaptations of a morpholine ring of the prototype pan-PI3K inhibitor ZSTK474 yielded PI3Kβ selective compounds, where the selectivity largely derives from an interaction with the non-conserved Asp862 residue, as shown by site directed mutagenesis. The most PI3Kβ selective inhibitor from the series was studied in detail through a series of in vitro and in vivo functional studies. MIPS-9922, 10 potently inhibited ADP-induced washed platelet aggregation. It also inhibited integrin αIIbβ3 activation and αIIbβ3 dependent platelet adhesion to immobilized vWF under high shear. It prevented arterial thrombus formation in the in vivo electrolytic mouse model of thrombosis without inducing prolonged bleeding or excess blood loss. Copyright © 2016 Elsevier Masson SAS.

Exclusive production of $\\eta\\pi^-$ and $\\eta'\\pi^-$ has been studied with a $191\\,\\textrm{GeV}/c$ $\\pi^-$ beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal different odd/even angular momentum ($L$) characteristics in the inspected invariant mass range up to $3\\,\\textrm{GeV}/c^2$. A striking similarity between the two systems is observed for the $L=2,4,6$ intensities (scaled by kinematical factors) and the relative phases. The known resonances $a_2(1320)$ and $a_4(2040)$ are in line with this similarity. In contrast, a strong enhancement of $\\eta'\\pi^-$ over $\\eta\\pi^-$ is found for the $L=1,3,5$ waves, which carry non-$q\\bar q$ quantum numbers. The $L=1$ intensity peaks at $1.7\\,\\textrm{GeV}/c^2$ in $\\eta'\\pi^-$ and at $1.4\\,\\textrm{GeV}/c^2$ in $\\eta\\pi^-$, the corresponding phase motions with respect to $L=2$ are different.

Melanoma is the most aggressive and deadly form of cutaneous neoplasm due to its propensity to metastasize. Oncogenic BRAF drives sustained activation of the BRAF/MEK/ERK (MAPK) pathway and cooperates with PI3K/AKT/mTOR (PI3K) signaling to induce epithelial to mesenchymal transition (EMT), leading to cell invasion and metastasis. Therefore, targeting these pathways is a promising preventive/therapeutic strategy. We have shown that fisetin, a flavonoid, reduces human melanoma cell invasion by inhibiting EMT. In addition, fisetin inhibited melanoma cell proliferation and tumor growth by downregulating the PI3K pathway. In this investigation, we aimed to determine whether fisetin can potentiate the anti-invasive and anti-metastatic effects of sorafenib in BRAF-mutated melanoma. We found that combination treatment (fisetin + sorafenib) more effectively reduced the migration and invasion of BRAF-mutated melanoma cells both in vitro and in raft cultures compared to individual agents. Combination treatment also effectively inhibited EMT as observed by a decrease in N-cadherin, vimentin and fibronectin and an increase in E-cadherin both in vitro and in xenograft tumors. Furthermore, combination therapy effectively inhibited Snail1, Twist1, Slug and ZEB1 protein expression compared to monotherapy. The expression of MMP-2 and MMP-9 in xenograft tumors was further reduced in combination treatment compared to individual agents. Bioluminescent imaging of athymic mice, intravenously injected with stably transfected CMV-luciferase-ires-puromycin.T2A.EGFP-tagged A375 melanoma cells, demonstrated fewer lung metastases following combination treatment versus monotherapy. Our findings demonstrate that fisetin potentiates the anti-invasive and anti-metastatic effects of sorafenib. Our data suggest that fisetin may be a worthy adjuvant chemotherapy for the management of melanoma.

Ir(ppy){sub 2}(VPHD) (ppy=2-phenyl pyridine, VPHD=6-(4-vinylphenyl)-2,4-hexanedione) was copolymerized with methyl methacrylate (MMA). The copolymer had high quantum yield of 52.3{+-}0.5% in dilute ethyl acetate solution, and the yield increased around 45% than that of the iridium monomer. The maximum emission peaks for the copolymers shifted from 515 to 489 nm while the iridium complex content was less than 0.005 mol% in the feed. The blue emission at 489 nm and the green emission at 520 nm were analyzed by Lorenz function. They are attributed to {sup 1}MLCT and {sup 3}MLCT emissions, respectively. - Highlights: > PMMA-Ir(ppy){sub 2}(VPHD) as luminescent material with high yield of 53%. > The blue color emission at 489 nm from {sup 1}MLCT in conformity with Lorenz function. > The quantum yield for the copolymer increases 45% than that of the iridium monomer. > The {sup 3}MLCT Ex. intensity versus the monomer concentration is in conformity with Boltzmann function.

Jupiter's upper atmospheric temperature is considerably higher than that predicted by Solar Extreme Ultraviolet (EUV) heating alone. Simulations incorporating magnetosphere-ionosphere coupling effects into general circulation models have, to date, struggled to reproduce the observed atmospheric temperatures under simplifying assumptions such as azimuthal symmetry and a spin-aligned dipole magnetic field. Here we present the development of a full three-dimensional thermosphere model coupled in both hemispheres to an axisymmetric magnetosphere model. This new coupled model is based on the two-dimensional MIT model presented in Yates et al., 2014. This coupled model is a critical step towards to the development of a fully coupled 3D MIT model. We discuss and compare the resulting thermospheric flows, energy balance and MI coupling currents to those presented in previous 2D MIT models.

For flexible film supercapacitor, high areal capacitance is a main evaluating indicator. In this paper, bacterial cellulose (BC) with special three-dimensional structure was used as the natural flexible base material. Fe3O4 nanoparticles with average diameter of 20 nm were synthesized on the surface of BC fibers. The conductive path polypyrrole (PPy) was introduced as shell of BC/Fe3O4 fibers to further improve the pseudo capacitance in 1 mol/L H2SO4 solution. Besides, the BC/Fe3O4@PPy was used for supercapacitor application in acid electrolyte, and delivered higher areal capacitance compared to other Fe3O4 composites in previous reports. The obtained BC/Fe3O4@PPy film showed excellent mechanical strength (tensile strength reached 11 MPa), high areal specific capacitance (5.4 F cm-2 at active mass of 8.4 mg cm-2), and long cycle life (1.95 F cm-2 over 3500 cycles).

This thesis describes two studies of the four-body decays of the neutral charm meson, $D^{0} \\rightarrow K^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ and its doubly Cabibbo-suppressed counterpart $D^{0} \\rightarrow K^{+}\\pi^{-}\\pi^{-}\\pi^{+}$. The first analysis is a model-independent determination of parameters that characterise the phase space averaged interference between the two amplitudes associated with each of these decay modes. The analysis exploits quantum correlations in $D\\bar{D}$ pairs produced from the $\\psi(3770)$ resonance in data collected with the CLEO-c detector.

Studies of the favoured mode, $D^{0} \\rightarrow K^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ , are the most precise studies of the amplitude to date and this data set is one of the largest samples of any decay mode to be studied using an amplitud...

Choice vs. voice? PPI policies and the re-positioning of the state in England and Wales.

Science.gov (United States)

Hughes, David; Mullen, Caroline; Vincent-Jones, Peter

2009-09-01

CONTEXT AND THESIS: Changing patient and public involvement (PPI) policies in England and Wales are analysed against the background of wider National Health Service (NHS) reforms and regulatory frameworks. We argue that the growing divergence of health policies is accompanied by a re-positioning of the state vis-à-vis PPI, characterized by different mixes of centralized and decentralized regulatory instruments. Analysis of legislation and official documents, and interviews with policy makers. In England, continued hierarchical control is combined with the delegation of responsibilities for the oversight and organization of PPI to external institutions such as the Care Quality Commission and local involvement networks, in support of the government's policy agenda of increasing marketization. In Wales, which has rejected market reforms and economic regulation, decentralization is occurring through the use of mixed regulatory approaches and networks suited to the small-country governance model, and seeks to benefit from the close proximity of central and local actors by creating new forms of engagement while maintaining central steering of service planning. Whereas English PPI policies have emerged in tandem with a pluralistic supply-side market and combine new institutional arrangements for patient 'choice' with other forms of involvement, the Welsh policies focus on 'voice' within a largely publicly-delivered service. While the English reforms draw on theories of economic regulation and the experience of independent regulation in the utilities sector, the Welsh model of local service integration has been more influenced by reforms in local government. Such transfers of governance instruments from other public service sectors to the NHS may be problematic.

Polypyrrole (PPY)-Zinc Oxide (ZnO) nanocomposites with varying concentration of ZnO (1:1-1:4) were prepared via in-situ polymerization technique by using pyrrole monomer in the presence of ammonium persulphate (APS) as oxidant. Globular morphology of PPY and sheet like structure of ZnO was examined using FESEM and EDAX. FTIR showed the presence of vibration modes in fingerprint region (1500 cm-1-500 cm-1) for metal oxides confirming the presence and interaction of ZnO with the polymer matrix in nanocomposites. Amorphous nature of PPY and hexagonal wurtzite structure of ZnO was confirmed using XRD with average crystallite size within 20 nm-30 nm. PANI-ZnO (1:1) exhibited blue shift in comparison to PPY (neat) and optimized optical band gap ∼ 1.81 eV. The effect of carrier concentration was investigated using electrochemical analyzer and maximum current was recorded for PANI-ZnO (1:1). The highest conductance was calculated for PANI-ZnO (1:1) ∼ 7.3242 × 10-3 S using current -voltage characteristics. Thermal stability was found to be increasing with the increase in ZnO concentration PANI-ZnO nanocomposite.

The phosphatidylinositol 3-kinase (PI3K) pathway is commonly deregulated in cancer and, thus, PI3K has been recognized as an attractive molecular target for novel anti-cancer therapies. However, the effect of PI3K inhibitors on T-cell function, a key component of antitumor immunity, has been scantly explored. The objective of this study was to investigate the effect on human T-cell activation of two PI3K inhibitors currently being tested in clinical trials: PX-866 and BKM120. Their activity against a leukemic T cell line was also assessed. For that purpose, Jurkat cells or anti-CD3/anti-CD28 stimulated human peripheral blood mononuclear cells were cultured in the presence of different concentrations of PX-866 or BKM120 and their effect on T-cell proliferation, apoptosis, expression of activation markers and cytokine secretion was analyzed by flow cytometry. In addition, Akt and Erk phosphorylation was analyzed by Western blotting. Both PX-866 and BKM120 decreased viability of Jurkat cells and blocked cell cycle progression. Regarding primary T cells, both compounds similarly inhibited expression of activation markers and cytokine secretion, although they did not induce apoptosis of stimulated T cells. Interestingly, we found differences in their ability to block T-cell proliferation and IL-2 secretion, exerting BKM120 a more potent inhibition. These disparate effects could be related to differences observed in PI3K/Akt and RAS/MEK/ERK signaling between PX-866 and BKM120 treated cells. Our results suggest that, when selecting a PI3K inhibitor for cancer therapy, immunosuppressive characteristics should be taken into account in order to minimize detrimental effects on immune function.

The microtubule interacting and trafficking (MIT) domain is a small protein module that is conserved in proteins of diverged function, such as Vps4, spastin and sorting nexin 15 (SNX15). The molecular function of the MIT domain is protein-protein interaction, in which the domain recognizes peptides containing MIT-interacting motifs. Recently, we identified an evolutionarily related domain, 'variant' MIT domain at the N-terminal region of the microtubule severing enzyme katanin p60. We found that the domain was responsible for binding to microtubules and Ca(2+). Here, we have examined whether the authentic MIT domains also bind Ca(2+). We found that the loop between the first and second α-helices of the MIT domain binds a Ca(2+) ion. Furthermore, the MIT domains derived from Vps4b and SNX15a showed phosphoinositide-binding activities in a Ca(2+)-dependent manner. We propose that the MIT domain is a novel membrane-associating domain involved in endosomal trafficking.

The authors calculate the complete next-to-next-to-leading order QCD corrections to the charm contribution of the rare decay K{sup +} {yields} {pi}{sup +}{nu}{bar {nu}}. They encounter several new features, which were absent in lower orders. They discuss them in detail and present the results for the two-loop matching conditions of the Wilson coefficients, the three-loop anomalous dimensions, and the two-loop matrix elements of the relevant operators that enter the next-to-next-to-leading order renormalization group analysis of the Z-penguin and the electroweak box contribution. The inclusion of the next-to-next-to-leading order QCD corrections leads to a significant reduction of the theoretical uncertainty from {+-} 9.8% down to {+-} 2.4% in the relevant parameter P{sub c}(X), implying the leftover scale uncertainties in {Beta}(K{sup +} {yields} {pi}{sup +}{nu}{bar {nu}}) and in the determination of |V{sub td}|, sin 2{beta}, and {gamma} from the K {yields} {pi}{nu}{bar {nu}} system to be {+-} 1.3%, {+-} 1.0%, {+-} 0.006, and {+-} 1.2{sup o}, respectively. For the charm quark {ovr MS} mass m{sub c}(m{sub c}) = (1.30 {+-} 0.05) GeV and |V{sub us}| = 0.2248 the next-to-leading order value P{sub c}(X) = 0.37 {+-} 0.06 is modified to P{sub c}(X) = 0.38 {+-} 0.04 at the next-to-next-to-leading order level with the latter error fully dominated by the uncertainty in m{sub c}(m{sub c}). They present tables for P{sub c}(X) as a function of m{sub c}(m{sub c}) and {alpha}{sub s}(M{sub z}) and a very accurate analytic formula that summarizes these two dependences as well as the dominant theoretical uncertainties. Adding the recently calculated long-distance contributions they find {Beta}(K{sup +} {yields} {pi}{sup +}{nu}{bar {nu}}) = (8.0 {+-} 1.1) x 10{sup -11} with the present uncertainties in m{sub c}(m{sub c}) and the Cabibbo-Kobayashi-Maskawa elements being the dominant individual sources in the quoted error. They also emphasize that improved calculations of the long

Full Text Available A novel series of PI3Kβ (Phosphatidylinositol-3-kinases beta subunit inhibitors with the structure of benzothiazole scaffold have been designed and synthesized. All the compounds have been evaluated for inhibitory activities against PI3Kα, β, γ, δ and mTOR (Mammalian target of rapamycin. Two superior compounds have been further evaluated for the IC50 values against PI3Ks/mTOR. The most promising compound 11 displays excellent anti-proliferative activity and selectivity in multiple cancer cell lines, especially in the prostate cancer cell line. Docking studies indicate the morpholine group in 2-position of benzothiazole is necessary for the potent antitumor activity, which confirms our design is reasonable.

The results of a wire chamber spectrometer experiment studying anti K*(890) production in the reaction K/sup -/p..-->..K/sup -/..pi../sup +/n at 13 GeV are presented. Strong forward structure is observed for mod(t)pi..)/sup 2/ in the s-channel density matrix elements and differential cross section. These features are similar to those observed in ..pi../sup -/p..-->..rho/sup 0/n data and are characteristic of ..pi.. exchange. In contrast in the intermediate, mod(t)approximately 0.2 GeV/sup 2/, and large momentum transfer regions anti K*(890) production is dominated by the natural parity rho-A/sub 2/ exchange contribution.

The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the pi- pi- pi+ final state using a 190 GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1 GeV^2/c^2. The well-known resonances a1(1260), a2(1320), and pi2(1670) are clearly observed. In addition, the data show a significant natural parity exchange production of a resonance with spin-exotic quantum numbers J^PC = 1-+ at 1.66 GeV/c^2 decaying to rho pi. The resonant nature of this wave is evident from the mass-dependent phase differences to the J^PC = 2-+ and 1++ waves. From a mass-dependent fit a resonance mass of 1660 +- 10+0-64 MeV/c^2 and a width of 269+-21+42-64 MeV/c^2 is deduced.

Feasibility study of the {eta}'{yields} {pi}{sup +} {pi}{sup -} {pi}{sup 0} decay using WASA-at-COSY apparatus

Energy Technology Data Exchange (ETDEWEB)

Zielinski, M.

2008-07-15

One of the objectives of the vast physics programme of the recently commissioned WASA-at-COSY facility is the study of fundamental symmetries via the measurements of the {eta} and {eta}' mesons decays. Especially interesting are isospin violating hadronic precesses of these mesons into 3{pi} systems driven by the term of QCD Lagrangian which depends on the mass difference of the u and d quarks. When an {eta} or an {eta}' meson is created in the hadronic reaction signals from such decays may be significantly obscured by the prompt production of {pi} mesons. In this thesis we present the estimation of the upper limit of the background due to prompt pion production for the {eta}'{yields}3{pi}{sup 0} and {eta}'{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} decays. Using the data from proton-proton collisions measured by the COSY-11 group we have extracted differential cross sections for the multimeson production with the invariant mass corresponding to the mass of the {eta}' meson. Based on these results and on parametrizations of the total cross sections for the {eta}' meson as well as parametrization of the upper limit for the prompt pi{sup +}pi{sup -}pi{sup 0} production in the collisions of protons we discuss in details the feasibility of a measurement of the {eta}' meson decay into 3{pi} channels with the WASA-at-COSY facility. Based on the chiral unitary approach the value of the branching ratio BR({eta}'{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}) was recently predicted to be about 1%. We show that the WASA-at-COSY has a potential to verify this result empirically. (orig.)

Atrial fibrillation/tachycardia (AF/AT) may result in inappropriate therapies in implantable cardioverter-defibrillators (ICDs). The post-pacing interval (PPI) and tachycardia cycle length difference (PPI - TCL) has been previously demonstrated to indicate the proximity of the pacing site to a tachycardia origin. We postulated that the PPI and PPI - TCL would be greater in AT/AF vs. ventricular tachycardia (VT) after episodes of failed anti-tachycardia pacing (ATP). This was a single-centre, retrospective study evaluating consecutive patients implanted with dual (DR)/biventricular (BIV) ICDs. Stored electrograms were used to determine whether the ATP captured the arrhythmia and the arrhythmia did not present with primary or secondary termination. Measurements were done using manual calipers. A total of 155 patients were included. There were 79 BIV and 76 DR devices. In total, 39 episodes were identified in 20 patients over a 23-month follow-up period. A total of 76 sequences of ATP (burst/ramp) were delivered, 28 (37%) of them inappropriate. Fifty-one events (18 AT/AF and 33 VT) were compared. The mean PPI was 693 ± 96 vs. 512 ± 88 ms (P failed ATP differs significantly between AF/AT and VT and are therefore useful indices to discriminate between supraventricular tachycardia and VT in ICDs.

We study the processes e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}-{gamma}, K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0}{gamma}, and K{sup +}K{sup -}K{sup +}K{sup -}{gamma}, where the photon is radiated from the initial state. About 84000, 8000, and 4200 fully reconstructed events, respectively, are selected from 454 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the e{sup +}e{sup -} center-of-mass energy, so that the K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} data can be compared with direct measurements of the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -} reaction. No direct measurements exist for the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0} or e{sup +}e{sup -} {yields} K{sup +}K{sup -}K{sup +}K{sup -} reactions, and we present an update of our previous result with doubled statistics. Studying the structure of these events, we find contributions from a number of intermediate states, and extract their cross sections. In particular, we perform a more detailed study of the e{sup +}e{sup -} {yields} {phi}(1020){pi}{pi}{gamma} reaction, and confirm the presence of the Y (2175) resonance in the {phi}(1020)f{sub 0}(980) and K{sup +}K{sup -} f{sub 0}(980) modes. In the charmonium region, we observe the J/{psi} in all three final states and in several intermediate states, as well as the {phi}(2S) in some modes, and measure the corresponding branching fractions.

The first observation of the decays $\\bar{B}^0_{s}\\to D_s^+K^-\\pi^+\\pi^-$ and $\\bar{B}^0\\to D_s^+K^-\\pi^+\\pi^-$ are reported using an integrated luminosity of 1.0 fb$^{-1}$ recorded by the LHCb experiment. The branching fractions, normalized with respect to $\\bar{B}^0_{s}\\to D_s^+\\pi^-\\pi^+\\pi^-$ and $\\bar{B}^0_{s}\\to D_s^+K^-\\pi^+\\pi^-$, respectively, are measured to be $\\frac{B(\\bar{B}^0_{s}\\to D_s^+K^-\\pi^+\\pi^-)}{B(\\bar{B}^0_{s}\\to D_s^+\\pi^-\\pi^+\\pi^-)} = (5.2\\pm0.5\\pm0.3)\\times10^{-2}$, $\\frac{B(\\bar{B}^0\\to D_s^+K^-\\pi^+\\pi^-)}{B(\\bar{B}^0_{s}\\to D_s^+K^-\\pi^+\\pi^-)} = 0.54\\pm0.07\\pm0.07$, where the first uncertainty is statistical and the second is systematic.

This work had as main objective the synthesis and characterization of LDH [Co-Al-Cl] method by hydrolysis of urea and then its synthesized polypyrrole coating by chemically targeting the application as adsorbent dichlorophenoxyacetic acid (2,4-D). The x-ray diffractogram of well defined showed diffraction peaks corresponding to the planes 003, 006, 009 and 110 which allow them to rhombohedral indexes and lamellar structure. The composite LDH / Ppi had a percentage of 49% herbicide retention in aqueous solution. From the investigated adsorption isotherm models that more fit the experimental data was the Freundlich, so it could be inferred that the interaction between the LDH / Ppi and the herbicide was physical, ie an rapid, reversible adsorption and does not specify.

Model-Independent Analysis of the Neutron-Proton Final-State Interaction Region in the $\\pi\\pi \\to pn\\pi^+$ Reaction

CERN Document Server

Uzikov, Yu N

2001-01-01

Experimental data on the \\pi\\pi\\to pn\\pi^+ reaction measured in an exclusive two-arm experiment at 800 MeV show a narrow peak arising from the strong proton-neutron final-state interaction. It was claimed, within the framework of a certain model, that this peak contained up to a 25 % spin-singlet final-state contribution. By comparing the data with those of \\pi\\pi\\to d\\pi^+ in a largely model-independent way, it is here demonstrated that at all the angles measured the whole of the peak could be explained as being due to spin-triplet final states, with the spin-singlet being at most a few percent. Good qualitative agreement with the measured proton analysing power is also found within this approach.

b-baryon light-cone distribution amplitudes and a dynamical theory for [bq] [ anti b anti q]-tetraquarks

Energy Technology Data Exchange (ETDEWEB)

Hambrock, Christian

2011-04-15

In my thesis I present our work on the bottom-baryon light-cone distribution amplitudes (LCDAs) and on the [bq][ anti b anti q]-tetraquarks. For the former we extended the known LCDAs for the ground state baryon {lambda}{sub b} to the entire b-baryon ground state multiplets and included s-quark mass-breaking effects. The LCDAs form crucial input for the calculations of characteristic properties of b-baryon decays. In this context they can for example be used in the calculation of form factors for semileptonic flavor-changing neutral-current (FCNC) decays. For the [bq][ anti b anti q]-tetraquarks, we calculated the tetraquark mass spectrum for all quarks q=u,d,s,c in a constituent Hamiltonian quark model. We estimated the electronic width by introducing a generalized Van Royen-Weisskopf formula for the tetraquarks, and evaluated the partial hadronic two-body and total decay widths for the tetraquarks with quantum numbers J{sup PC}=1{sup --}. With this input, we performed a Breit-Wigner fit, including the tetraquark contributions, to the inclusive R{sub b}-spectrum measured by BaBar. The obtained {chi}{sup 2}/d.o.f. of the BaBar R{sub b}-scan data is fairly good. The resulting fits are suggestive of tetraquark states but not conclusive. We developed a model to describe the transitions e{sup +}e{sup -}{yields}Y{sub b}{yields}{upsilon}(nS)({pi}{sup +}{pi}{sup -},K{sup +}K{sup -},{eta}{pi}{sup 0}), in which Y{sub b} is a 1{sup --} tetraquark state. The model includes the exchange of light tetraquark and meson states. We used this model to fit the invariant-mass and helicity spectra for the dipionic final state measured by Belle and used the results to estimate the spectra of the channels e{sup +}e{sup -}{yields}Y{sub b}{yields}{upsilon}(nS)(K{sup +}K{sup -},{eta}{pi}{sup 0}). The spectra are enigmatic in shape and magnitude and defy an interpretation in the framework of the standard bottomonia, requesting either an interpretation in terms of exotic states, such as

Starting from (subtracted) hyperbolic dispersion relations for {pi}N scattering, which are based on the general principles of Lorentz invariance, unitarity, crossing and analyticity as well as isospin symmetry, we propose a closed system of (subtracted) hyperbolic partial wave dispersion relations for the partial waves f{sup I}{sub l{+-}}({radical}(s)) of the s-channel reaction {pi}N{yields}{pi}N and the partial waves f{sup J}{sub {+-}}(t) of the t-channel reaction {pi}{pi}{yields} anti NN in the spirit of Roy and Steiner. A key step to the ultimate goal of solving this Roy-Steiner system is to first solve the corresponding (subtracted) Muskhelishvili-Omnes problem with inelasticities and a finite matching point for the lowest t-channel partial waves f{sup 0}{sub +}(t), f{sup 1}{sub {+-}}(t). The recent status of this ongoing effort is presented.

Proton pump inhibitor (PPI)-refractory heartburn may be due to persistent gastro-oesophageal reflux, oesophageal hypersensitivity or functional heartburn (FH). The differentiation between non-erosive reflux disease (NERD) and FH may be very difficult. However, this differentiation is important for appropriate therapeutic management. Dilated intercellular spaces (DIS), papillary elongation (PE) and basal cell hyperplasia (BCH) can be all assessed by light microscopy. Whether these mucosal abnormalities allow the differentiation of NERD from FH in PPI-refractory patients is uncertain. To assess histopathological findings by light microscopy in patients with refractory heartburn to differentiate NERD from FH. Sixty-two patients with PPI-refractory symptoms underwent EGD and MII-pH after pausing PPI medication for 2 weeks before investigation. Twenty-five subjects without upper gastrointestinal symptoms were included as controls. Symptom assessment was based on the reflux disease questionnaire (RDQ). Biopsies were taken 3-5 cm above the gastro-oesophageal junction. DIS, PE, BCH and infiltration of immune cells were evaluated and a sum score was calculated. Based on endoscopy and MII-pH, GERD was diagnosed in 43 patients (NERD: 20; ERD: 23) and FH in 19 patients. There was no difference in symptoms between the groups. Each individual histopathological item was different between the groups (P < 0.0001). Between NERD and FH, the most significant difference was found for DIS and the histopathological sum score (P < 0.001). These findings suggest that oesophageal biopsies are useful to differentiate NERD from FH. Increased DIS and a histological sum score are the most significant histopathological abnormalities in NERD as compared with FH. © 2013 John Wiley & Sons Ltd.

Choice vs. voice? PPI policies and the re‐positioning of the state in England and Wales

Science.gov (United States)

Hughes, David; Mullen, Caroline; Vincent‐Jones, Peter

2009-01-01

Abstract Context and Thesis  Changing patient and public involvement (PPI) policies in England and Wales are analysed against the background of wider National Health Service (NHS) reforms and regulatory frameworks. We argue that the growing divergence of health policies is accompanied by a re‐positioning of the state vis‐à‐vis PPI, characterized by different mixes of centralized and decentralized regulatory instruments. Method  Analysis of legislation and official documents, and interviews with policy makers. Findings  In England, continued hierarchical control is combined with the delegation of responsibilities for the oversight and organization of PPI to external institutions such as the Care Quality Commission and local involvement networks, in support of the government’s policy agenda of increasing marketization. In Wales, which has rejected market reforms and economic regulation, decentralization is occurring through the use of mixed regulatory approaches and networks suited to the small‐country governance model, and seeks to benefit from the close proximity of central and local actors by creating new forms of engagement while maintaining central steering of service planning. Whereas English PPI policies have emerged in tandem with a pluralistic supply‐side market and combine new institutional arrangements for patient ‘choice’ with other forms of involvement, the Welsh policies focus on ‘voice’ within a largely publicly‐delivered service. Discussion  While the English reforms draw on theories of economic regulation and the experience of independent regulation in the utilities sector, the Welsh model of local service integration has been more influenced by reforms in local government. Such transfers of governance instruments from other public service sectors to the NHS may be problematic. PMID:19754688

Charm meson oscillations are observed in a time-dependent analysis of the ratio of $D^0\\to K^+\\pi^-\\pi^+\\pi^-$ to $D^0\\to K^-\\pi^+\\pi^-\\pi^+$ decay rates, using data corresponding to an integrated luminosity of $3.0\\,{\\rm fb}^{-1}$ recorded by the LHCb experiment. The measurements presented are sensitive to the phase-space averaged ratio of doubly Cabibbo-suppressed to Cabibbo-favoured amplitudes $r_{D}^{K3\\pi}$ and the product of the coherence factor $R_{D}^{K3\\pi}$ and a charm mixing parameter $y^{'}_{K3\\pi}$. The constraints measured are $r_{D}^{K3\\pi}=(5.67 \\pm 0.12)\\times10^{-2}$, which is the most precise determination to date, and $R_{D}^{K3\\pi} \\cdot y^{'}_{K3\\pi} = (0.3 \\pm 1.8)\\times 10^{-3}$, which provides useful input for determinations of the CP-violating phase $\\gamma$ in $B^\\pm \\to D K^\\pm, D \\to K^\\mp\\pi^\\pm\\pi^\\mp\\pi^\\pm$ decays. The analysis also gives the most precise measurement of the $D^0\\to K^+\\pi^-\\pi^+\\pi^-$ branching fraction, and the first observation of $D^0-\\bar D^0$ oscillations...

[Digestive and extra-digestive complications of nonsteroidal anti-inflammatory drugs. Preventive and curative strategies].

1997-04-01

The authors review the digestive ulceration risk factors and the criteria for selecting a non steroidal antiinflammatory (NSAI), included the most recent drugs, such as selective anti-cyclo-oxygenases 2. They actualize the preventive strategies and insist on the values of misoprostol and of slow acting anti-rheumatic drugs. In the case of digestive ulcerations, they plead for the immediate stop of the NSAI and its replacement if necessary by corticosteroids, for the prescription of a proton pump inhibitor (PPI) or mesalazine according to the localisation of the lesion, finally for the eradication within 8 days of Helicobacter pylori.

Lymphocyte numbers are increased in the lungs of chronic obstructive pulmonary disease (COPD) patients. Phosphatidylinositol-3-kinase delta (PI3Kδ) is involved in lymphocyte activation. We investigated the effect of PI3Kδ inhibition on cytokine release from COPD lymphocytes. We also evaluated phosphorylated ribosomal S6 protein (rS6) as a potential biomarker of PI3Kδ activation. Peripheral blood mononuclear cells (PBMCs) and bronchoalveolar lavage (BAL) cells isolated from healthy never smokers (HNS), smokers (S) and COPD patients were stimulated to induce a T cell receptor response. The effects of a PI3Kδ specific inhibitor (GSK045) on cytokine release and rS6 phosphorylation were measured by Luminex and flow cytometry respectively. The effects of GSK045 on cytokine production from PHA stimulated chopped lung samples were investigated. GSK045 reduced cytokine release from PBMCs, BAL cells and chopped lung. Inhibition was greatest in the chopped lung model, with approximately 80% inhibition of interferon (IFN) γ, interleukin (IL)-2, IL-17 and IL-10. PI3Kδ inhibition suppressed rS6 phosphorylation in unstimulated airway T-lymphocytes by up to 60%. Inhibition of PI3Kδ suppressed T cell cytokine production in COPD patients. rS6 phosphorylation shows potential as a biomarker to assess PI3Kδ activity. © 2017 John Wiley & Sons Australia, Ltd.

In this study, a new support has been developed by immobilization of α-amylase onto modified magnetic Fe 3 O 4 -nanoparticles. The characterization of soluble and immobilized α-amylases with regards to kinetic parameters, pH, thermal stability and reusability was studied. The effect of polypyrrole/silver nanocomposite (PPyAgNp) percentage on weight of Fe 3 O 4 and pH on the immobilization of α-amylase was studied. The highest immobilization efficiency (75%) was detected at 10% PPyAgNp/Fe 3 O 4 -nanocomposite and pH 7.0. Immobilization of α-amylase on PPyAgNp/Fe 3 O 4 -nanocomposite was characterized by FT-IR spectroscopy and scanning electron microscopy. The reusability of the immobilized enzyme activity was 80% of its initial activity after 10 reuses. The immobilized enzyme was more stable towards pH, temperature and metal ions compared with soluble enzyme. The kinetic study appeared higher affinity of immobilized enzyme (K m 2.5 mg starch) compared with soluble enzyme (K m 3.5 mg starch). In conclusion, the immobilization of α-amylase on PPyAgNp/Fe 3 O 4 -nanocomposite could successfully be used in industrial and medical applications.

Evidence is presented for the decay $B_c+\\rightarrow J/\\psi 3\\pi^+2\\pi^-$ using proton-proton collision data, corresponding to an integrated luminosity of 3fb$^{-1}$, collected with the LHCb detector. A signal yield of $32\\pm8$ decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of the $B_c^+\\rightarrow J/\\psi 3\\pi^+ 2\\pi^-$ decay to that of the $B_c^+ \\rightarrow J/\\psi \\pi^+$ decay is measured to be $$ \\frac{Br (B_c^+ \\rightarrow J/\\psi 3\\pi^+2\\pi^)}{Br (B_c^+ \\rightarrow J/\\psi \\pi^+)} = 1.74\\pm0.44\\pm0.24, $$ where the first uncertainty is statistical and the second is systematic.

We have measured the ratio $\\sigma(e^+e^-\\rightarrow\\pi^+\\pi^-\\gamma)/\\sigma(e^+e^-\\rightarrow \\mu^+\\mu^-\\gamma)$, with the KLOE detector at DA$\\Phi$NE for a total integrated luminosity of $\\sim$ 240 pb$^{-1}$. From this ratio we obtain the cross section $\\sigma(e^+e^-\\rightarrow\\pi^+\\pi^-)$. From the cross section we determine the pion form factor $|F_\\pi|^2$ and the two-pion contribution to the muon anomaly $a_\\mu$ for $0.592pi\\pi}<0.975$ GeV, $\\Delta^{\\pi\\pi} a_\\mu$= $({\\rm 385.1\\pm1.1_{stat}\\pm2.7_{sys+theo}})\\times10^{-10}$. This result confirms the current discrepancy between the Standard Model calculation and the experimental measurement of the muon anomaly.

A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K pi pi system and peaks at roughly the same mass as the Q in diffractive K pi pi production. The polarization properties of the 1/sup +/S(K* pi ) and 1/sup +/S(K rho ) waves differ from those of the diffractive 1/sup +/ wave. There is some evidence for a resonance contribution to 1/sup +/S(K* pi ). The strong 2/sup +/ wave is identified with K*(1420) and the K rho /K* pi decay branching ratio determined to be 0.36+or-0.10. An enhancement with spin-parity 1 /sup -/ is observed under the K*(1420). (14 refs).

We present a study of ten B-meson decays to a D{sup (*)}, a proton-antiproton pair, and a system of up to two pions using BABAR's data set of 455 x 10{sup 6} B{bar B} pairs. Four of the modes {bar B}{sup 0} {yields} D{sup 0}p{bar p}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}, {bar B}{sup 0} {yields} D{sup +}p{bar p}{pi}{sup -}, {bar B}{sup 0} {yields} D{sup ast+}p{bar p}{pi}{sup -} are studied with improved statistics compared to previous measurements; six of the modes (B{sup -} {yields} D{sup 0}p{bar p}{pi}{sup -}, B{sup -} {yields} D*{sup 0}p{bar p}{pi}{sup -}, {bar B}{sup 0} {yields} D{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, B{sup -} {yields} D{sup +}p{bar p}{pi}{sup -}{pi}{sup -}, B{sup -} {yields} D{sup ast+}p{bar p}{pi}{sup -}{pi}{sup -}) are first observations. The branching fractions for 3- and 5-body decays are suppressed compared to 4-body decays. Kinematic distributions for 3-body decays show non-overlapping threshold enhancements in m(p{bar p}) and m(D{sup (*)0}p) in the Dalitz plots. For 4-body decays, m(p{pi}{sup -}) mass projections show a narrow peak with mass and full width of (1497.4 {+-} 3.0 {+-} 0.9)MeV/c{sup 2} and (47 {+-} 12 {+-} 4)MeV/c{sup 2}, respectively, where the first (second) errors are statistical (systematic). For 5-body decays, mass projections are similar to phase space expectations. All results are preliminary.

Thin-layer chromatography of polyphosphoinositides from platelet extracts: interference by an unknown phospholipid

Different ratios of radioactive polyphosphoinositides in platelets pulse-labelled with 32p-orthophosphate have been reported by various laboratories. We studied whether these differences originate from differences in methodology. Extracts of 32p-Pi labelled human platelets were prepared at various times after gel-filtration and phosphatidylinositol (PI)-, mono (PIP)- and bisphosphate (PIP2) were separated by thin-layer chromatography using four different solvent systems. The 32p-levels in PIP and PIP2 remained constant during one hour after gel-filtration, whereas 32p-PI increased continuously and more than doubled within the first h. In two of the systems PIP co-chromatographed with a radioactive compound which separated well from PIP in the two other systems. This unknown compound was also labelled with 3H-glycerol, 3H-inositol and 3H-arachidonic acid, but it was metabolically and functionally different from the polyphosphoinositides. Both the co-chromatography of this unknown phospholipid and the increase in 32p-PI in gel-filtered platelets can explain the difference in 32p-labelling in phosphoinositides reported in the literature

A new analysis of S-wave production amplitudes for the reaction {pi}{sup -}p{yields}{pi}{sup +}{pi}{sup -}n on a transversely polarized target is performed. It is based on the results obtained by CERN-Cracow-Munich collaboration in the {pi}{pi} energy range from 600 MeV to 1600 MeV at 17.2 GeV/c {pi}{sup -} momentum. Energy-independent separation of the S-wave pseudoscalar amplitude ({pi} exchange) from the pseudovector amplitude (a{sub 1} exchange) is carried out using assumptions much weaker than those in all previous analyses. We show that, especially around 1000 MeV and around 1500 MeV, the a{sub 1} exchange amplitude cannot be neglected. The scalar-isoscalar {pi}{pi} phase shift are calculated using fairly weak assumptions. Our results are consistent both with the so called ``up`` and the well-known ``down`` solution, provided we choose those in which the S-wave phases increase slower with the effective {pi}{pi} mass than the P-wave phases. Above 1420 MeV both sets of phase shifts increase with energy faster than in the experiment on an unpolarized target. This fact can be related to the presence of scalar resonance f{sub o}(1500).

Oral bioavailability of the ether lipid plasmalogen precursor, PPI-1011, in the rabbit: a new therapeutic strategy for Alzheimer's disease

Directory of Open Access Journals (Sweden)

Wood Paul L

Full Text Available Abstract Introduction Docosahexaenoic acid (DHA and DHA-containing ethanolamine plasmalogens (PlsEtn are decreased in the brain, liver and the circulation in Alzheimer's disease. Decreased supply of plasmalogen precursors to the brain by the liver, as a result of peroxisomal deficits is a process that probably starts early in the AD disease process. To overcome this metabolic compromise, we have designed an orally bioavailable DHA-containing ether lipid precursor of plasmalogens. PPI-1011 is an alkyl-diacyl plasmalogen precursor with palmitic acid at sn-1, DHA at sn-2 and lipoic acid at sn-3. This study outlines the oral pharmacokinetics of this precursor and its conversion to PlsEtn and phosphatidylethanolamines (PtdEtn. Methods Rabbits were dosed orally with PPI-1011 in hard gelatin capsules for time-course and dose response studies. Incorporation into PlsEtn and PtdEtn was monitored by LC-MS/MS. Metabolism of released lipoic acid was monitored by GC-MS. To monitor the metabolic fate of different components of PPI-1011, we labeled the sn-1 palmitic acid, sn-2 DHA and glycerol backbone with13C and monitored their metabolic fates by LC-MS/MS. Results PPI-1011 was not detected in plasma suggesting rapid release of sn-3 lipoic acid via gut lipases. This conclusion was supported by peak levels of lipoic acid metabolites in the plasma 3 hours after dosing. While PPI-1011 did not gain access to the plasma, it increased circulating levels of DHA-containing PlsEtn and PtdEtn. Labeling experiments demonstrated that the PtdEtn increases resulted from increased availability of DHA released via remodeling at sn-2 of phospholipids derived from PPI-1011. This release of DHA peaked at 6 hrs while increases in phospholipids peaked at 12 hr. Increases in circulating PlsEtn were more complex. Labeling experiments demonstrated that increases in the target PlsEtn, 16:0/22:6, consisted of 2 pools. In one pool, the intact precursor received a sn-3

Data on the charge-exchange reaction pi /sup -/p to ( pi /sup +/ pi /sup -/ pi /sup 0/)n have been taken at beam momenta of 12 and 15 GeV /c, using the CERN Omega Multiparticle Spectrometer. A partial-wave analysis has been made of the (3 pi )/sup 0/ system. Both natural and unnatural spin-parity production was observed. The natural parity states can be identified with established resonances. In addition a natural spin-parity enhancement is observed at a mass of about 2 GeV/c /sup 2/ with J/sup P/=4/sup +/ preferred. This effect is called the A /sub 2/*(2030). The unnatural spin-parity production found is consistent with reggeized Deck model predictions. No unambiguous A/sub 1/ or A/sub 3/ production is observed.

Amplitude Analysis of B0 to K^ pi^-pi^0 and Evidence of Direct CP Violation in B to K^* pi decays

Energy Technology Data Exchange (ETDEWEB)

Lees, J.P.

2011-11-04

We analyze the decay B{sup 0} {yields} K{sup +} {pi}{sup -} {pi}{sup 0} with a sample of 454 million B{bar B} events collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, and extract the complex amplitudes of seven interfering resonances over the Dalitz plot. These results are combined with amplitudes measured in B{sup 0} {yields} K{sup 0}{sub s}{pi}{sup +}{pi}{sup -} decays to construct isospin amplitudes from B{sup 0} {yields} K{sup *}{pi} and B{sup 0} {yields} {rho}K decays. We measure the phase of the isospin amplitude {Phi}{sub 3/2}, useful in constraining the CKM unitarity triangle angle {gamma} and evaluate a CP rate asymmetry sum rule sensitive to the presence of new physics operators. We measure direct CP violation in B{sup 0} {yields} K{sup *+}{pi}{sup -} decays at the level of 3 {sigma} when measurements from both B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} and B{sup 0} {yields} K{sup 0}{sub s}{pi}{sup +}{pi}{sup -} decays are combined.

The proposed experiment is a further development of the DIRAC experiment already running at CERN PS. Up to now more than 21000 $\\pi^+\\pi^-$ pairs originated from the $\\pi^+\\pi^-$ atom ($A_{2\\pi}$) breakup were identified and the overall accuracy of the $A_{2\\pi}$ lifetime is about 9% in accordance with the DIRAC proposal. This measurement allowed to extract the difference $|a_0-a_2|$ of $s$-wave $\\pi\\pi$-scattering length with accuracy of 4.3%. The observation of long-lived (metastable) $A_{2\\pi}$ states will be performed with the same setup. This observation opens a possibility to measure the energy difference between $ns$ and $np$ states and to determine the value of another combination $2a_0+a_2$ of $\\pi\\pi$ scattering length in a model-independent way. In combination with the first measurement it allows to get $a_0$ and $a_2$ separately. An additional measurement of the multiple scattering angles in different materials with accuracy better than 1% will be performed in parallel with the observation. This m...

Parallelization Experience with Four Canonical Econometric Models Using ParMitISEM

Directory of Open Access Journals (Sweden)

Nalan Baştürk

2016-03-01

Full Text Available This paper presents the parallel computing implementation of the MitISEM algorithm, labeled Parallel MitISEM. The basic MitISEM algorithm provides an automatic and flexible method to approximate a non-elliptical target density using adaptive mixtures of Student-t densities, where only a kernel of the target density is required. The approximation can be used as a candidate density in Importance Sampling or Metropolis Hastings methods for Bayesian inference on model parameters and probabilities. We present and discuss four canonical econometric models using a Graphics Processing Unit and a multi-core Central Processing Unit version of the MitISEM algorithm. The results show that the parallelization of the MitISEM algorithm on Graphics Processing Units and multi-core Central Processing Units is straightforward and fast to program using MATLAB. Moreover the speed performance of the Graphics Processing Unit version is much higher than the Central Processing Unit one.

We critically evaluate the isovector GMO sumrule for the charged $\\pi N N$ coupling constant using recent precision data from $\\pi ^-$p and $\\pi^-$d atoms and with careful attention to systematic errors. From the $\\pi ^-$d scattering length we deduce the pion-proton scattering lengths ${1/2}(a_{\\pi ^-p}+a_{\\pi ^-n})=(-20\\pm 6$(statistic)$ \\pm 10$ (systematic))~$\\cdot 10^{-4}m_{\\pi_c}^{-1}$ and ${1/2}(a_{\\pi ^-p}-a_{\\pi ^-n})=(903 \\pm 14)\\cdot 10^{-4}m_{\\pi_c}^{-1}$. From this a direct evaluation gives $g^2_c(GMO) =14.20\\pm 0.07$(statistic)$\\pm 0.13$(systematic) or $f^2_c= 0.0786\\pm 0.0008$.

Helicobacter sp. MIT 01-6451 has been detected in SPF mice kept in Japan. To characterize strain MIT 01-6451, its infection route during fetal and neonatal life and effects on pregnancy were investigated using immunocompetent and immunodeficient mouse strains (BALB/c, C57BL/6, and SCID). MIT 01-6451 was detected in the uterus, vagina, and mammary glands of 50% of infected SCID mice, whereas these tissues were all negative in immunocompetent mice. No fetal infections with MIT 01-6451 were detected at 16-18 days after pregnancy in any mouse strain. In newborn mice, MIT 01-6451 was detected in intestinal tissue of C57BL/6 and SCID mice at 9-11 days after birth, but not in BALB/c mice. The IgA and IgG titers to MIT 01-6451 in sera of C57BL/6 female mice were significantly lower than those of BALB/c mice. Although no significant differences in the number of newborns per litter were observed between MIT 01-6451-infected and MIT 01-6451-free dams, the birth rate was lower in infected SCID mice than in control SCID mice. The present results indicated that MIT 01-6451 infects newborn mice after birth rather than by vertical transmission to the fetus via the placenta and that MIT 01-6451 infection shows opportunistically negative effects on the birth rate. In addition, the maternal immune response may affect infection of newborn mice with MIT 01-6451 through breast milk.

AgPi: Agents on Raspberry Pi

Full Text Available The Raspberry Pi and its variants have brought with them an aura of change in the world of embedded systems. With their impressive computation and communication capabilities and low footprint, these devices have thrown open the possibility of realizing a network of things in a very cost-effective manner. While such networks offer good solutions to prominent issues, they are indeed a long way from being smart or intelligent. Most of the currently available implementations of such a network of devices involve a centralized cloud-based server that contributes to making the necessary intelligent decisions, leaving these devices fairly underutilized. Though this paradigm provides for an easy and rapid solution, they have limited scalability, are less robust and at times prove to be expensive. In this paper, we introduce the concept of Agents on Raspberry Pi (AgPi as a cyber solution to enhance the smartness and flexibility of such embedded networks of physical devices in a decentralized manner. The use of a Multi-Agent System (MAS running on Raspberry Pis aids agents, both static and mobile, to govern the various activities within the network. Agents can act autonomously or on behalf of a human user and can collaborate, learn, adapt and act, thus contributing to embedded intelligence. This paper describes how Tartarus, a multi-agent platform, embedded on Raspberry Pis that constitute a network, can bring the best out of the system. To reveal the versatility of the concept of AgPi, an application for a Location-Aware and Tracking Service (LATS is presented. The results obtained from a comparison of data transfer cost between the conventional cloud-based approach with AgPi have also been included.

The Micro Imaging Technology (MIT) 1000 Rapid Microbial Identification (RMID) System is a device that uses the principles of light scattering coupled with proprietary algorithms to identify bacteria after being cultured and placed in a vial of filtered water. This specific method is for pure culture identification of Listeria spp. A total of 81 microorganisms (55 isolates) were tested by the MIT 1000 System, of which 25 were Listeria spp. and 30 a variety of other bacterial species. In addition, a total of 406 tests over seven different ruggedness parameters were tested by the MIT 1000 System to determine its flexibility to the specifications stated in the MIT 1000 System User Guide in areas where they might be deviated by a user to shorten the test cycle. Overall, MIT concluded that the MIT 1000 System had an accuracy performance that should certify this Performance Test Method for the identification of Listeria spp. This report discusses the tests performed, results achieved, and conclusions, along with several reference documents to enable a higher understanding of the technology used by the MIT 1000 System.

Using a sample of 4.7 fb/sup -1/ integrated luminosity accumulated with the CLEO II detector at the Cornell Electron Storage Ring (CESR) , we investigate the mass spectrum and resonant structure in tau /sup -/ to K/sup -/ pi /sup +/ pi /sup -/ nu /sub tau / decays. We measure the relative fractions of K/sub 1/(1270) and K/sub 1/(1400) resonances in these decays, as well as the K/sub 1/ masses and widths. Our fitted K/sub 1/ resonances are somewhat broader than previous hadroproduction measurements, and in agreement with recent CERN LEP results from tau decay. The larger central value of our measured width supports models which attribute the small tau /sup -/ to K/sup -/ pi /sup +/ pi /sup -/ nu /sub tau / branching fraction to larger K/sub 1/ widths than are presently tabulated. We also determine the K/sub a/-K/sub b/ mixing angle theta /sub K/. (22 refs) .

Graphical abstract: Polypyrrole(PPy) film has improved the rate performance of LiMn{sub 2}O{sub 4} efficiently due to its excellent conductivity. PPy@LiMn{sub 2}O{sub 4} could provide more energy under the higher power than pristine LMO. - Highlights: • The PPy layer on the surface of LMO particles hasn’t been studied in LiMn{sub 2}O{sub 4} so far. • The solvent in the synthesis process of PPy@LMO is absolute ethyl alcohol. • The differences of surface-modification between the PPy and PI for LMO. • The analyses of rate performances are through specific power. - Abstract: Polypyrrole (PPy) is an excellent conductive polymer and the study on its utilization in the surface modification of the LiMn{sub 2}O{sub 4} (LMO) is few. In this work, the structure, morphology and electrochemical performance of surface-modified LiMn{sub 2}O{sub 4} composites with PPy and polyimides (PI) were discussed. The crystal structure, chemical bonds and morphology were characterized through X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), respectively. Moreover, the specific power and cycling performance were tested at room and high (55 °C) temperature. The PPy@LMO (surface-modified LMO composites with PPy) shows better performances than the pristine LMO. The addition of PPy not only weakens the corrosion caused by electrolyte, but also improves the discharge capacity at higher rates. The charge transfer resistance of the PPy@LMO is much lower than that of the pristine LMO after cycling.

The solid polymer electrolyte based conducting polymer actuator was presented. In the preparation of acutuator module, an ionic liquid impregnated a synthetic rubber (NBR) and PPy were used as a solid polymer electrolyte and conducting polymer, respectively. An ionic liquid, 1-butyl-3-methylimidazolium bis (trifluoromethyl sulfonyl)imide (BMITFSI) is gradually dispersed into the NBR film and the conducting polymer, PPy was synthesized on the surface of NBR. The ionic conductivity of new type solid polymer electrolyte as a function of the immersion time was investigated. The cyclic voltammetry responsed and the redox switching dynamics of PEDOT in NBR matrix were studied. The displacement of the actuator was measured by laser beam.

A study of the interaction ..pi../sup -/p ..-->.. n..pi../sup +/..pi../sup -/ is reported where the neutron was produced fast and forward in the laboratory. The data were obtained using an 8 GeV/c ..pi../sup -/ beam that was focused on a liquid hydrogen target located inside the University of Illinois--Argonne National laboratory streamer chamber. The chamber was triggered on the interaction of a fast, forward neutral hadron in thick plate optical spark chambers. A total of 866 events had an acceptable 3-constraint fit to ..pi../sup -/p ..-->.. n..pi../sup +/..pi../sup -/ and satisfied other selection criteria. The data were characterized by backward production of the final states n rho/sup 0/, nf/sup 0/, and ..delta../sup -/(1232)..pi../sup +/. Differential cross sections and decay angular distributions for these resonant states are presented and the implications for the production mechanisms discussed. 20 references.

The resonant substructures of $B^0 \\to \\overline{D}^0 \\pi^+\\pi^-$ decays are studied with the Dalitz plot technique. In this study a data sample corresponding to an integrated luminosity of 3.0 fb$^{-1}$ of $pp$ collisions collected by the LHCb detector is used. The branching fraction of the $B^0 \\to \\overline{D}^0 \\pi^+\\pi^-$ decay in the region $m(\\overline{D}^0\\pi^{\\pm})>2.1$ GeV$/c^2$ is measured to be $(8.46 \\pm 0.14 \\pm 0.29 \\pm 0.40) \\times 10^{-4}$, where the first uncertainty is statistical, the second is systematic and the last arises from the normalisation channel $B^0 \\to D^*(2010)^-\\pi^+$. The $\\pi^+\\pi^-$ S-wave components are modelled with the Isobar and K-matrix formalisms. Results of the Dalitz plot analyses using both models are presented. A resonant structure at $m(\\overline{D}^0\\pi^-) \\approx 2.8$ GeV$/c^{2}$ is confirmed and its spin-parity is determined for the first time as $J^P = 3^-$. The branching fraction, mass and width of this structure are determined together with those of the $D...

Starting from the strong gravity theory of Salam-Isham-Strathdee the M.I.T. bag is identified as a certain region of the global extension of a De Sitter-Schwarzschild solution. As a result the M.I.T. bag radius, a geometrical interpretation of the binding Lagrangian term and a rate of decaying of the ''bag manifold'' into the flat space (which, however, does not lead to observable quark wave functions) are obtained.

Full Text Available Pyrrole monomer was chemically polymerized onto SrCO3-Sr(OH2 powders to obtain SrCO3-Sr(OH2/polypyrrole nanocomposite to be used as a candidate for photocatalytic degradation of methylene blue dye (MB. The material was characterized by Fourier transform infrared (FTIR spectroscopy, UV/Vis spectroscopy, and X-ray diffraction (XRD. It was observed from transmission electronic microscopy (TEM analysis that the reported synthesis route allows the production of SrCO3-Sr(OH2 nanoparticles with particle size below 100 nm which were embedded within a semiconducting polypyrrole matrix (PPy. The SrCO3-Sr(OH2 and SrCO3-Sr(OH2/PPy nanocomposites were tested in the photodegradation of MB dye under visible light irradiation. Also, the effects of MB dye initial concentration and the catalyst load on photodegradation efficiency were studied and discussed. Under the same conditions, the efficiency of photodegradation of MB employing the SrCO3-Sr(OH2/PPy nanocomposite increases as compared with that obtained employing the SrCO3-Sr(OH2 nanocomposite.

We estrapolate the PI-PI amplitudes with isospin one and two in the t-channel onto the imaginary ν approximately equal to (s - u)/4msub(π) axis in the complex ν-plane by means of ''optimal'' Poisson weighted dispersion relations. The values obtained are compared with expected theoretical asymptotic behaviours and found not to be inconsistent with the possibility of a ''precocious asymptotism'' setting for imaginary ν-values

A maximum likelihood fit finds the following branching fractions: {Beta}(B{sup 0} {yields} K{sup 0}{pi}{sup +}{pi}{sup -}) = (43.0 {+-} 2.3 {+-} 2.3) x 10{sup -6}, {Beta}(B{sup 0} {yields} f{sub 0}({yields} {pi}{sup +}{pi}{sup -})K{sup 0}) = (5.5 {+-} 0.7 {+-} 0.5 {+-} 0.3) x 10{sup -6} and {Beta}(B{sup 0} {yields} K*{sup +}{pi}{sup -}) = (11.0 {+-} 1.5 {+-} 0.5 {+-} 0.5) x 10{sup -6}. For these results, the first uncertainty is statistical, the second is systematic, and the third (if present) is due to the effect of interference from other resonances.

It is recommended that research studies are carried out with or by patients and the public through their involvement from the beginning and in as many stages as possible (known as PPI). Some studies formally invite patients and the public to participate in interviews and focused group discussions to collect views about topics (known as qualitative research). In our study on financial incentives for giving up smoking in pregnancy and breastfeeding, we combined both PPI and qualitative research to include the views of women with a range of experiences of smoking and breastfeeding. We involved two mother and baby groups in disadvantaged areas of North East Scotland and North West England as research partners on our team. First, we asked members to comment on our research plans and documents, which is standard PPI. Second, we asked members to participate in voice recorded discussions, contributing to qualitative research data. These discussions revealed different views from those that we heard through research interviews. They allowed us to develop more relevant research tools and resources. Members also helped us to identify people outside the groups who we could interview. Combining involvement and participation helped us to include the views of a wide range of women from 'harder-to-reach' groups who don't usually take part in research. This was important because the research was intended for women who could benefit from incentives to stop smoking in pregnancy and breastfeed, often present in such groups. Positive continuing relationships and trust improved on involvement or participation alone. ᅟ. Patient and public involvement (PPI) in all research studies is recommended from the earliest point and in as many stages as possible. Qualitative research is also recommended in the early stages of designing complex intervention trials. Combining both together might enable inclusion of 'harder-to-reach' perspectives from the target population(s), particularly when the

Full Text Available Polypyrrole films were generated on high purity aluminum substrates under anodic polarization from aqueous electrolytes comprised of pyrrole and sodium dodecylbenzene sulfonate. The methods employed to characterize the polymer films included scanning electron microscopy, Fourier-transform infrared and X-photoelectron spectroscopy and X-ray diffraction. PPY/SDBS films revealed nodular morphology with occasional appearing of "dendrites", high level of protonation, excess of counter-anions ([S]/[N] > [N+]/[N] and high degrees of disorder.

The study of the K{sub L,S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} decay modes in the NA48 experiment at CERN is presented in this thesis. Using the full data samples collected in 1998 and 1999, 1285 {+-} 37 events K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} have been extracted over a background of 41 events. The measured branching ratio is: BR(K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[3,16{+-}0,09(stat.){+-}0,16(syst.)] x 10{sup -7}. Concerning the K{sub S} mode, a signal of 768 {+-} 28 candidates has been observed over a negligible background. The obtained branching ratio is: BR(K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[4,28{+-}0,18(stat.){+-}0,26(syst.)] x 10{sup -5}. Both results are in very good agreement with the values predicted by phenomenological models where the processes K{sub L,S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} are described in terms of inner Bremsstrahlung and direct emission contributions. In the K{sub L} mode, the presence of two components with opposed CP states leads to a large asymmetry A in the distribution of the angle {phi} between the decay planes of the two pions and the two electrons. The detailed analysis of the K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} mode ends up to a non-zero value of the asymmetry with more than 4 standard deviations: A(K{sub L} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[13,8{+-}2,8(stat.){+-}2,3(syst.)]%. This result is a clear manifestation of CP violation in this channel. The large value of this asymmetry, in excellent agreement with theoretical prediction, accounts for CP violation in the K{sup 0}-K-bar{sup 0} mixing. Furthermore, it was verified that in the K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -} mode which is dominated by the inner Bremsstrahlung component, the asymmetry is compatible with zero: A(K{sub S} {yields} {pi}{sup +}{pi}{sup -}e{sup +}e{sup -})=[-0,8{+-}3,6(stat.){+-}1,2(syst.)]%.

Grundlegende Steuerungsverfahren im heterogenen Logistiknetz mit Kanban

Dickmann, Eva; Dickmann, Philipp; Lödding, Hermann; Möller, Niklas; Rücker, Thomas; Schneider, Herfried M.; Zäh, Michael F.

In vielen Unternehmen werden heterogene (verschiedene) Steuerungen in einem abgestimmten Konzept kombiniert. Je nach Anwendungsfall und Rahmenbedingungen werden Kombinationen allgemein bekannter Steuerungen oder Steuerungsvarianten gemischt eingesetzt, um eine optimale Steuerung für unterschiedliche Fälle zu erreichen. Hierbei stehen neben den bekannten und weit verbreiteten Methoden, wie Material Requirements Planning (MRP) oder Kanban, auch weniger bekannte oder neue Methoden zur Auswahl, wie die Produktionssteuerung mit dezentraler, bestandsorientierter Fertigungsregelung (DBF). Kanban ist ein simples und effizientes Steuerungskonzept, das in der klassischen Form für spezifische einfache Anwendungsfälle umsetzbar ist. Hochentwickelte Steuerungsalgorithmen können helfen, komplexe Abläufe optimal abzubilden. Mit einer grundlegenden Vereinfachung der Abläufe kann allerdings in vielen Fällen ein wesentlich stärkerer und umfassender Verbesserungseffekt erzielt werden. Die wesentliche Fragestellung sollte folglich lauten: Warum ist der Ablauf nicht mit einer einfachen Steuerung wie Kanban abzubilden? Um die Vorteile des Konzepts auch in untypischen Bereichen anwenden zu können, sind jedoch verschiedene Varianten oder Kanban-ähnliche Steuerungsmethoden entstanden. Darüber hinaus sind in der Praxis hybride Steuerungen im Einsatz, welche so kombiniert werden, dass die Zusammensetzung anspruchsvolle Eigenschaftsbilder noch exakt abbildet. In der Praxis basieren die Steuerungsentscheidungen nur zu einem kleinen Teil auf den eigentlichen Steuerungsalgorithmen, wie sie uns das MRP-System zur Verfügung stellt. Moderne Steuerungswelten" schließen alle relevanten Informationsquellen in eine heterogene Entscheidungsmatrix mit ein. Letztlich zählt nicht, ob die Entscheidung auf den Informationen aus dem MRP-System oder auf Softfacts basierend getroffen wurde, sondern nur, ob die Entscheidung erfolgreich war.

A partial-wave analysis of the (3 pi )/sup 0/ system produced peripherally in the reaction K/sup -/p to pi /sup +/ pi /sup -/ pi /sup 0/ Lambda at 4.2 GeV/c is presented. The observation of the weak Lambda decay allows a determination of all the transverse production amplitudes except for two phases. The production of known resonances having decay modes other than 3 pi is used to test the isobar model ansatz. Significant omega (783), phi (1020) and A/sub 2/(1310) production is observed. The spin parity of the omega *(1675) is established as 3/sup -/. No evidence for production of other resonances, such as axial vector-mesons, is found. (23 refs).

This thesis describes a Dalitz plot analysis of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays. The data sample comprises 213 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center in California (SLAC). Preliminary results are presented for measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892){sup +}{pi}{sup -} and {rho}(770){sup -}K{sup +}. Observations of B{sup 0} decays to the K{pi} S-wave intermediate states, K*{sub 0}(1430){sup +}{pi}{sup -} and K*{sub 0}(1430){sup 0}{pi}{sup 0}, are reported. Evidence of the decay B{sup 0} {yields} K*(892){sup 0}{pi}{sup 0} is seen. We set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.

Neuroprotection has received considerable attention as a strategy for the treatment of Parkinson's disease (PD). Deprenyl (Selegiline) is a promising candidate for neuroprotection; however, its cytoprotective mechanism has not been fully clarified. Here, we report a novel cytoprotective mechanism of deprenyl involving PI3K and Nrf2-mediated induction of oxidative stress-related proteins. Deprenyl increased the expression of HO-1, PrxI, TrxI, TrxRxI, γGCS, and p62/A170 in SH-SY5Y cells. Deprenyl also induced the nuclear accumulation of Nrf2 and increased the binding activity of Nrf2 to the enhancer region of human genomic HO-1. The Nrf2-mediated induction of antioxidative molecules was controlled by PI3K. Indeed, furthermore, neurotrophin receptor TrkB was identified as an upstream signal for PI3K-Nrf2 activation by deprenyl. These results suggest that the cytoprotective effect of deprenyl is, in part, dependent on Nrf2-mediated induction of antioxidative proteins, suggesting that activation of the PI3K-Nrf2 system may be a useful therapeutic strategy for PD

This work is part of the first experiment to detect neutral pions and protons in coincidence in kinematically complete measurements. The reaction was studied on /sup 16/O (using water targets) at several pion angles: theta/sub ..pi../sup 0// = 70/degree/, 80/degree/, 110/degree/, and 130/degree/. At theta/sub ..pi../sup 0// = 110/degree/ measurements were also made on /sup 56/Fe, /sup 120/Sn, and /sup 208/Pb. The neutral pions were detected with the LAMPF ..pi../sup 0/ spectrometer, while the protons were detected in a vertical array of plastic-scintillator ..delta..E-E telescopes, each spanning 8.5 msr. Energy spectra of the differential cross sections d/sup 4/sigma/dE/sub ..pi../sup 0// dE/sub p/d..cap omega../sub ..pi../sup 0//d..cap omega../sub p/ were obtained for each proton telescope and subsequently integrated over proton and pion energy and proton angle. The characteristics of these spectra are consistent with a quasi-free description of the (..pi../sup +/,..pi../sup 0/p) reaction. The angular dependence of dsigma/d..cap omega../sub ..pi../sup 0//(theta/sub ..pi../sup 0//) for /sup 16/O(..pi../sup +/,..pi../sup 0/p) was found to be in accordance with that of the cross section for the corresponding free reaction at backward ..pi../sup 0/ angles. For the /sup 16/O(..pi../sup +/,..pi../sup 0/p) reaction, events in which a p-shell nucleon had been removed were identified. The p-shell events were found to constitute only 40--50% of the total cross section for quasi-free one-nucleon removal. The (..pi../sup +/,..pi../sup 0/p) cross section at theta/sub ..pi../sup 0// = 110/degree/ proved to be almost the same for all target nuclei, possibly slightly decreasing as a function of A. 102 refs., 108 figs., 24 tabs.

We look at methods to determine the weak phases $\\phi_2$ and $\\phi_3$ from $B \\to \\pi\\pi$ and $K\\pi$ decays within the perturbative QCD approach. We obtain quite interesting bounds on $\\phi_2$ and $\\phi_3$ from experimental measurement in B-factory: $55^o \\leq \\phi_2 \\leq 100^o$ and $51^o \\leq \\phi_3 \\leq 129^o$. Specially we predict the possibility of large direct CP violation effect in $B^0 \\to \\pi^{+}\\pi^{-} (23\\pm7 %)$ decay.

Aluminium (ALUM) is used as experimental and clinical adjuvant for parenteral vaccine formulation. It is also contained in anti-acid drugs like sucralfate (SUC). These anti-acids have been shown to cause sensitization to food proteins via elevation of the gastric pH. The aim of this study was to assess the oral adjuvant properties of ALUM, alone or contained in SUC, in a BALB/c mouse model. Mice were fed SUC plus ovalbumin (OVA) and compared with groups where ALUM or proton pump inhibitors (PPI) were applied as adjuvants. The humoral and cellular immune responses were assessed on antigen-specific antibody and cytokine levels. The in vivo relevance was investigated in skin tests. The highest OVA-specific immunoglobulin G1 (IgG1) and IgE antibody levels were found in mice fed with OVA/SUC, followed by OVA/ALUM-treated animals, indicating a T helper 2 (Th2) shift in both groups. Antibody levels in other groups revealed lower (OVA/PPI-group) or baseline levels (control groups). Positive skin tests confirmed an allergic response in anti-acid or adjuvant-treated animals. Our data show for the first time that ALUM acts as a Th2-adjuvant via the oral route. This suggests that orally applied SUC leads to an enhanced risk for food allergy, not only by inhibiting peptic digestion but also by acting as a Th2-adjuvant by its ALUM content.

Study of the reaction {pi}{sup -}p {yields} {pi}{sup -}{pi}{sup 0} p at 2.77 GeV/c carried out in the CERN 2 meter large liquid hydrogen bubble chamber at the proton synchrotron, shows that 70 per cent of this reaction goes through {pi}{sup -}p {yields} {rho}{sup -}p channel. The high statistics allow us to specify the mass and the width of the {rho}{sup -} resonance. In other hand, if the {rho}{sup -} production parameters are independent of the {rho}{sup -} width, it is not the same case for the decay parameters. In the second part, the Chew-Low extrapolation method allows us to determine the {pi}{sup -}{pi}{sup 0} elastic cross section to the pole, and the phase shifts of the P waves in the isospin 1 state and S waves in the isospin 2 state.

L'abondance de la statistique a permis de preciser la masse et la largeur de la resonance {rho}{sup -}. D'autre part, si les parametres de la production du {rho}{sup -} sont independants de la largeur de la resonance, il n'en est pas de meme des parametres de la desintegration.

A quark-diquark cascade model which includes flavor dependence and resonance effect is studied. The inclusive distributions of vector and pseudoscalar mesons and octet baryons and antibaryons in K/sup +/ and ..pi../sup +/ beam jets are analyzed. The contribution of decuplet baryons to the octet baryon spectra is very important in meson beam jet. The effects of the asymmetric u- and anti s-quark distributions in K/sup +/ and the SU(6)-symmetry breaking for the produced octet baryon are discussed in connection with the ..pi../sup +//K/sup +/ beam ratio and other data.

Dendrimers are an emerging class of polymeric nanoparticles with beneficial biomedical applications like early diagnostics, in vitro gene transfection or controlled drug delivery. However, the potential toxic impact of exposure on human health or the environment is often inadequately defined. Thus, polyamidoamine (PAMAM) dendrimers of generations G3.0, 3.5, 4.0, 4.5 and 5.0 and polypropylenimine (PPI) dendrimers G3.0, 4.0 and 5.0 were tested in zebrafish embryos for 96 h and human cancer cell lines for 24 h, to assess and compare developmental in vivo toxicity with cytotoxicity. The zebrafish embryo toxicity of cationic PAMAM and PPI dendrimers increased over time, with EC50 values ranging from 0.16 to just below 1.7 μM at 24 and 48 hpf. The predominant effects were mortality, plus reduced heartbeat and blood circulation for PPI dendrimers. Apoptosis in the embryos increased in line with the general toxicity concentration-dependently. Hatch and dechorionation of the embryos increased the toxicity, suggesting a protective role of the chorion. Lower generation dendrimers were more toxic in the embryos whereas the toxicity in the HepG2 and DU145 cell lines increased with increasing generation of cationic PAMAMs and PPI dendrimers. HepG2 were less sensitive than DU145 cells, with IC50 values ≥ 402 μM (PAMAMs) and ≤ 240 μM (PPIs) for HepG2 and ≤ 13.24 μM (PAMAMs) and ≤ 12.84 μM (PPIs) for DU145. Neither in fish embryos nor cells toxicity thresholds were determinable for anionic PAMAM G3.5 and G4.5. The study demonstrated that the cytotoxicity underestimated the in-vivo toxicity of the dendrimers in the fish embryos. - Highlights: • Zebrafish embryo toxicity of cationic PAMAM and PPI dendrimers increased over time. • Zebrafish embryo toxicity of cationic dendrimers did not increase with generation. • Cationic dendrimers induced apoptosis in zebrafish embryos. • Toxicity of cationic dendrimers was lower in HepG2 and DU145 than zebrafish embryos. �

Cryogenic silicon detectors and analysis of Primakoff contributions to the reaction {pi}{sup -}Pb {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}Pb at COMPASS

An important part of the physics programme of the COMPASS experiment at CERN is the measurement of reactions with hadron beam particles impinging on fixed targets at small momentum transfer. These measurements require tracking of charged particles with high precision, which is only reachable employing silicon microstrip detectors placed around the target, both as a part of the beam telescope and in the first part of the spectrometer. These detectors have been operated at a sensor temperature of 200 K starting with the 2009 beam time. They are cooled with liquid nitrogen in thin capillaries attached to the silicon sensors. For stable long-term operation, various extensions around the previously existing setup were required. Particularly the mechanical stability of the cooled detector modules concerning thermal deformation, as well as the cooling stability, have been improved to the level where installation in the experiment became feasible. The detector performance profits significantly from the cryogenic operation, so that a time resolution in the range of 1.4-1.8 ns and a spatial resolution of 4-6 {mu}m and 7-11 {mu}m (for two and one strips hit, respectively) is reached. This corresponds to an improvement of 15-20% with respect to the warm operation. Meson spectroscopy using a high-energetic pion beam impinging on heavy nuclear targets features both diffractive and Primakoff, i.e. electro-magnetic, production of the final state, the latter becoming competitive particularly at lowest momentum transfer t'. Four million exclusive {pi}{sup -}{pi}{sup -}{pi}{sup +} final state events, emerging from {pi}{sup -} beam scattering off a lead target, have been recorded during the COMPASS 2004 hadron run. About one million feature t' < 10{sup -3} GeV{sup 2}/c{sup 2}. Employing partial-wave analysis techniques, Primakoff-produced resonances, and the interference between Primakoff and diffractive production have been observed. Using the free decay of the kaon

The K sub L-> pi sup +pi sup - e sup + e sup - and K sub S-> pi sup +pi sup - e sup + e sup - decay modes have been studied in detail using the NA48 detector at the CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 K sub L-> pi sup +pi sup - e sup + e sup - candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement BR(K sub L -> pi sup +pi sup - e sup + e sup -)=(3.08+-0.20) x 10 sup - sup 7. The distribution of events in the sin phi cos phi variable, where phi is the angle between the pi sup +pi sup - and the e sup + e sup - decay planes in the kaon centre of mass, is found to exhibit a large CP-violating asymmetry with the value A subphi=(14.2+-3.6)%. For the K sub S-> pi sup +pi sup - e sup + e sup - decay channel, 621 candidates have been identified in the 1999 data sample with an estimated background contribution of 0.7 event. The corresponding branching ratio has been determined to be BR(K sub S-> pi ...

The exclusive channel polarized proton(polarized e,e prime p)pi0 was studied in the first and second nucleon resonance regions in the Q2 range from 0.187 to 0.770 GeV2 at Jefferson Lab using the CEBAF Large Acceptance Spectrometer (CLAS). Longitudinal target and beam-target asymmetries were extracted over a large range of center-of-mass angles of the pi0 and compared to the unitary isobar model MAID, the dynamic model by Sato and Lee, and the dynamic model DMT. A strong sensitivity to individual models was observed, in particular for the target asymmetry and in the higher invariant mass region. This data set, once included in the global fits of the above models, is expected to place strong constraints on the electrocoupling amplitudes A_{1/2} and S_{1/2} for the Roper resonance N(1400)P11, and the N(1535)S11 and N(1520)D13 states.

Acetone-water complexes at MRCI level using localized orbitals: n ->pi* and pi ->pi* electronic transitions

The n -> pi* and pi -> pi* vertical electronic transitions of acetone with two and four H2O which correspond to a first solvation shell are considered. By using localized orbitals, and thanks to the MRCI approach which permits to know the wave function, the role of the various solvent molecules...... is analysed in details. Distinguishing the solvent molecules allows one to consider them at different calculation levels. The methodology is to compare the spectra obtained with four H2O, with two H2O either in the acetone plane or in a perpendicular plane and when they are completely or partly frozen....

The reaction pp -> pf (pi+pi-pi0) ps has been studied at 450 GeV/c in an experiment designed to search for gluonic states. A spin analysis has been performed and the dPT filter applied. The analysis confirms the previous observation that all undisputed qqbar states are suppressed at small dPT. In addition, a clear difference is observed in the production mechanism for the eta and omega.

msiDBN: A Method of Identifying Critical Proteins in Dynamic PPI Networks

Full Text Available Dynamics of protein-protein interactions (PPIs reveals the recondite principles of biological processes inside a cell. Shown in a wealth of study, just a small group of proteins, rather than the majority, play more essential roles at crucial points of biological processes. This present work focuses on identifying these critical proteins exhibiting dramatic structural changes in dynamic PPI networks. First, a comprehensive way of modeling the dynamic PPIs is presented which simultaneously analyzes the activity of proteins and assembles the dynamic coregulation correlation between proteins at each time point. Second, a novel method is proposed, named msiDBN, which models a common representation of multiple PPI networks using a deep belief network framework and analyzes the reconstruction errors and the variabilities across the time courses in the biological process. Experiments were implemented on data of yeast cell cycles. We evaluated our network construction method by comparing the functional representations of the derived networks with two other traditional construction methods. The ranking results of critical proteins in msiDBN were compared with the results from the baseline methods. The results of comparison showed that msiDBN had better reconstruction rate and identified more proteins of critical value to yeast cell cycle process.

Dielectric parameters of free standing films of pure PVA (PolyvinylAlcohol) and PVA with varying concentrations of PVP(Polyvinylpyrrolidone) and Polypyrrole were prepared and studied in low frequency range (100Hz - 2MHz). The results show that dielectric constant, loss tangent and conductivity increase sharply on increasing the concentration of PVP above 50wt% in polymer matrix. PVA-PVP film with low concentration of PPy showed improvement in the values of complex permittivity, loss tangent and ac conductivity within the experimental frequency range. This eco - friendly polymeric material will be studied for its probable application for RFI/EMI shielding, biosensors, capacitors & insulation purposes.

Acacetin protects against cardiac remodeling after myocardial infarction by mediating MAPK and PI3K/Akt signal pathway

Full Text Available Since inhibiting cardiac remodeling is a critical treatment goal after myocardial infarction (MI, many drugs have been evaluated for this purpose. Acacetin is a flavonoid compound that has been shown to have anti-cancer, anti-mutagenic, anti-inflammatory and anti-peroxidative effects. In this study, we investigated whether acacetin is able to exert a protective effect against MI. One week after anterior wall standard MI surgeries or sham surgeries were performed in mice, acacetin was administered via gavage for two weeks. The results of echocardiographic and hemodynamic evaluation revealed that cardiac dysfunction significantly improved after acacetin treatment. H&E staining indicated that the ratio of the infarct size and the cardiomyocyte cross-sectional area was decreased by acacetin. Masson's staining detected that the fibrotic area ratio was evidently lower in the acacetin-treated MI group. TUNEL assays showed that acacetin ameliorated cardiomyocyte apoptosis after MI. RT-qPCR analysis showed that levels of hypertrophic and fibrotic markers were significantly decreased after acacetin treatment. Western blot analysis of various signaling pathway proteins showed that acacetin targets the MAPK and PI3K/Akt signaling pathways. Collectively, acacetin improves mouse left ventricular function and attenuates cardiac remodeling by inhibiting of the MAPK and PI3K/Akt signaling pathway.

A search for time-integrated CP violation in the Cabibbo-suppressed decay $D^0\\to\\pi^-\\pi^+\\pi^0$ is performed using for the first time an unbinned model-independent technique known as the energy test. Using proton-proton collision data, corresponding to an integrated luminosity of 2.0 fb$^{-1}$ collected by the LHCb detector at a centre-of-mass energy of $\\sqrt{s}$ = 8 TeV, the world's best sensitivity to CP violation in this decay is obtained. The data are found to be consistent with the hypothesis of CP symmetry with a $p$-value of (2.6$\\pm$ 0.5)$\\%$

We study the three-pion decays of the lightest isoscalar vector mesons, {omega} and {phi}, in a dispersive framework that allows for a consistent description of final-state interactions between all three pions. Our results are solely dependent on the phenomenological input for the pion-pion P-wave scattering phase shift. We predict the Dalitz plot distributions for both decays and compare our findings to recent measurements of the {phi}{yields}3{pi} Dalitz plot by the KLOE and CMD-2 collaborations. Dalitz plot parameters for future precision measurements of {omega}{yields}3{pi} are predicted. We also calculate the {pi}{pi} P-wave inelasticity contribution from {omega}{pi} intermediate states.

Ciobotaru, I.C.; Polosan, S.; Ciobotaru, C.C.

2014-01-01

The synthesis of organometallic compound with iridium and two types of ligands, quinoline and phenylpyridine, was done successfully. The absorption spectra of this compound have shown broad peaks in a visible region assigned to metal-to-ligands charge transfer and in UV region assigned to intraligand absorptions. The photoluminescence spectra exhibit dual character in which the red emission is more intense than the green one. In cathodoluminescence measurements, under electron beam, the powder obtained after recrystallization from dichloromethane, shows similar behaviors with photoluminescence spectra. The cathodoluminescence images have shown a luminescent crystalline powder with triclinic structure. This compound exhibits combined vibrational modes, which proves the presence in the same molecule of both ligands. Density Functional Theory calculation was involved in order to identify the main vibrations of this compound. Highlights: • Mixed-ligand of IrQ(ppy) 2 synthesis which gives green and red phosphorescence due to the MCLT processes coming from two types of ligands. • Absorption, photoluminescence, infrared spectroscopy and cathodoluminescence measurements for characterization of IrQ(ppy) 2 organometallic compound. • Experimental results have been compared with the output files obtained from Density Functional Theory by using the Gaussian 03W software

This work had as main objective the synthesis and characterization of LDH [Co-Al-Cl] method by hydrolysis of urea and then its synthesized polypyrrole coating by chemically targeting the application as adsorbent dichlorophenoxyacetic acid (2,4-D). The x-ray diffractogram of well defined showed diffraction peaks corresponding to the planes 003, 006, 009 and 110 which allow them to rhombohedral indexes and lamellar structure. The composite LDH / Ppi had a percentage of 49% herbicide retention in aqueous solution. From the investigated adsorption isotherm models that more fit the experimental data was the Freundlich, so it could be inferred that the interaction between the LDH / Ppi and the herbicide was physical, ie an rapid, reversible adsorption and does not specify.

The aim of this study was to compare surface imaging, portal imaging, and skin marker set-up in radiotherapy of thoracic and pelvic regions, using cone beam computed tomography (CBCT) data as the gold standard. Twenty patients were included in this study. CBCT, surface acquisition (SA), and two orthogonal portal images (PI) were acquired during the first four treatment sessions. Patient set-up corrections, obtained by registering the planning CT with CBCT, were used as the gold standard. Registration results of the PI and SA were evaluated and compared with those obtained with CBCT. The advantage derived from using SA or PI verification systems over a skin marker set-up was also quantified. A statistically significant difference between PI and SA (in favour of PI) was observed in seven patients undergoing treatment of the pelvic region and in two patients undergoing treatment of the thoracic region. The use of SA or PI, compared with a skin marker set-up, improved patient positioning in 50% and 57 % of the thoracic fractions, respectively. For pelvic fractions, the use of PI was beneficial in 73 % of the cases, while the use of SA was beneficial in only 45 %. Patient positioning worsened with SA, particularly along longitudinal and vertical directions. PI yielded more accurate registration results than SA for both pelvic and thoracic fractions. Compared with the skin marker set-up, PI performances were superior to SA for pelvic fractions while comparable results were obtained for thoracic fractions. (orig.)

In this work, the sulfonic acid (–SO{sub 3}H) group terminated Fe{sub 3}O{sub 4}@SiO{sub 2} magnetic spheres were prepared. Polypyrrole (PPy) was in-situ polymerized on Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H spheres due to the dual roles of the –SO{sub 3}H groups: acting as both “anchoring sites” for adsorbing of pyrrole monomer and dopant agent in PPy. By adsorbing gold nanoseeds on the as-prepared Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H@PPy spheres followed the seed-mediated growth method, the multifunctional Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H@PPy@Au spheres were obtained. The application of Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H@PPy@Au spheres in surface-enhanced Raman scattering (SERS) was investigated, and the results exhibited the enhancement in the order of 10{sup 4} using 4-aminothiophenol as the probe molecule. - Highlights: • The sulfonic acid-terminated Fe{sub 3}O{sub 4}@SiO{sub 2} (Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H) spheres were prepared. • The –SO{sub 3}H groups of Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H spheres played dual roles in adsorbing pyrrole and protonating polypyrrole. • Fe{sub 3}O{sub 4}@SiO{sub 2}–SO{sub 3}H@PPy core/gold shell composites can act as SERS substrate for detecting 4-ATP molecule.

The long-term use of proton pump inhibitors (PPIs) exacerbates corpus atrophic gastritis in patients with Helicobacter pylori (H. pylori) infection. To identify a potential mechanism for this change, we discuss interactions between pH, bile acids, and H. pylori. Duodenogastric reflux, which includes bile, occurs in healthy individuals, and bile reflux is increased in patients with gastroesophageal reflux disease (GERD). Diluted human plasma and bile acids have been found to be significant chemoattractants and chemorepellents, respectively, for the bacillus H. pylori. Although only taurine conjugates, with a pKa of 1.8-1.9, are soluble in an acidic environment, glycine conjugates, with a pKa of 4.3-5.2, as well as taurine-conjugated bile acids are soluble in the presence of PPI therapy. Thus, the soluble bile acid concentrations in the gastric contents of patients with GERD after continuous PPI therapy are considerably higher than that in those with intact acid production. In the distal stomach, the high concentration of soluble bile acids is likely to act as a bactericide or chemorepellent for H. pylori. In contrast, the mucous layer in the proximal stomach has an optimal bile concentration that forms chemotactic gradients with plasma components required to direct H. pylori to the epithelial surface. H. pylori may then colonize in the stomach body rather than in the pyloric antrum, which may explain the occurrence of corpus-predominant gastritis after PPI therapy in H. pylori-positive patients with GERD.

Full Text Available In this article we introduce a new concept called Alpha-skew Pi-Armendariz rings (Alpha - S Pi - ARas a generalization of the notion of Alpha-skew Armendariz rings.Another important goal behind studying this class of rings is to employ it in order to design a modern algorithm of an identification scheme according to the evolution of using modern algebra in the applications of the field of cryptography.We investigate general properties of this concept and give examples for illustration. Furthermore, this paperstudy the relationship between this concept and some previous notions related to Alpha-skew Armendariz rings. It clearly presents that every weak Alpha-skew Armendariz ring is Alpha-skew Pi-Armendariz (Alpha-S Pi-AR. Also, thisarticle showsthat the concepts of Alpha-skew Armendariz rings and Alpha-skew Pi- Armendariz rings are equivalent in case R is 2-primal and semiprime ring.Moreover, this paper proves for a semicommutative Alpha-compatible ringR that if R[x;Alpha] is nil-Armendariz, thenR is an Alpha-S Pi-AR. In addition, if R is an Alpha - S Pi -AR, 2-primal and semiprime ring, then N(R[x;Alpha]=N(R[x;Alpha]. Finally, we look forwardthat Alpha-skew Pi-Armendariz rings (Alpha-S Pi-ARbe more effect (due to their properties in the field of cryptography than Pi-Armendariz rings, weak Armendariz rings and others.For these properties and characterizations of the introduced concept Alpha-S Pi-AR, we aspire to design a novel algorithm of an identification scheme.

Plumbagin and Quercetin are naturally occurring compounds which exhibit anti-cancerous activity. To evaluate the effect of radioiodination on cytotoxicity, both Plumbagin and Quercetin were radioiodinated with 125 I. 125 I-Plumbagin and 125 I-Quercetin could be prepared in moderate yields and good radiochemical purity and were characterized using reverse phase HPLC. In Swiss mice bearing fibrosarcoma, 125 I-Plumbagin showed a tumor uptake of ∼2.5%ID/g at 3 h p.i. and ∼0.5%ID/g at 24 h p.i on i.v. injection. When injected intratumorally, greater tumor uptake and retention was observed (∼20%ID/g at 3 h p.i. and ∼14%ID/g at 24 h p.i. respectively). (author)

Adaptive GSA-based optimal tuning of PI controlled servo systems with reduced process parametric sensitivity, robust stability and controller robustness.

This paper suggests a new generation of optimal PI controllers for a class of servo systems characterized by saturation and dead zone static nonlinearities and second-order models with an integral component. The objective functions are expressed as the integral of time multiplied by absolute error plus the weighted sum of the integrals of output sensitivity functions of the state sensitivity models with respect to two process parametric variations. The PI controller tuning conditions applied to a simplified linear process model involve a single design parameter specific to the extended symmetrical optimum (ESO) method which offers the desired tradeoff to several control system performance indices. An original back-calculation and tracking anti-windup scheme is proposed in order to prevent the integrator wind-up and to compensate for the dead zone nonlinearity of the process. The minimization of the objective functions is carried out in the framework of optimization problems with inequality constraints which guarantee the robust stability with respect to the process parametric variations and the controller robustness. An adaptive gravitational search algorithm (GSA) solves the optimization problems focused on the optimal tuning of the design parameter specific to the ESO method and of the anti-windup tracking gain. A tuning method for PI controllers is proposed as an efficient approach to the design of resilient control systems. The tuning method and the PI controllers are experimentally validated by the adaptive GSA-based tuning of PI controllers for the angular position control of a laboratory servo system.

Dennoch ist der Endpunkt der meisten klinischen Analysen rein anatomischer und funktioneller Natur. In der vorliegenden Untersuchung wurden die Einflüsse der operativen Rekonstruktion mit einem Netz prospektiv auf die LQ evaluiert. Patienten und Methoden: Bei insgesamt 111 Patientinnen mit Deszensus erfolgte zwischen 08/2005 und 12/2007 eine operative Versorgung mittels vaginaler Netzeinlage (anteriorer bzw. kompletter Mesh-Repair. Die LQ wurde prospektiv prä- und postoperativ anhand standardisierter LQ-Fragebögen erfasst. Ergebnisse: Präoperativ zeigte sich bei den Patientinnen eine signifikant reduzierte LQ gegenüber einem Normalkollektiv (p 0,01. Bei 7 % der Patientinnen mit anteriorem, und bei 11 % mit komplettem Mesh-Repair lag postoperativ kein adäquates klinisches Ergebnis vor. In diesem Kollektiv zeigte sich kein signifikanter Unterschied in den LQ-Tests prä- und postoperativ. Bei gutem postoperativem Ergebnis zeigte sich in der Gruppe mit anteriorer Netzeinlage lediglich bei 45 % (p = 0,021, bei kompletter Netzeinlage nur bei 31 % (p = 0,041 eine signifikant verbesserte LQ. Bei kleiner Fallzahl und kurzem Nachbeobachtungszeitraum kann eine gültige Aussage bezüglich der LQ nach Deszensuschirurgie mit Netzeinlage jedoch noch nicht getroffen werden.

The LHCb experiment has recorded the world's largest sample of charmed meson decays. This contribution presents a study of a $D^0$ meson decaying into a final state containing a neutral pion in LHCb. The search for $CP$ violation exploits a novel model-independent unbinned technique to assign a $p$-value for the no $CP$ violation hypothesis. With a data sample size exceeding that of previous measurements by almost an order of magnitude the world's best sensitivity is obtained. The $p$-value of no $CP$ violation hypothesis given data of $D^0\\rightarrow \\pi^-\\pi^+\\pi^0$ decay analysed is found to be $(2.6 \\pm 0.5)\\times 10^{-2}$.

Lens epithelial cell proliferation, migration, and transdifferentiation are involved in the development of subcapsular cataracts and postoperative capsular opacification (PCO). PI3K/Akt pathway is involved in the proliferation and migration of lens epithelial cells. Andrographolide is the main bioactive component of Andrographis paniculata and is known to possess anti-proliferative and anti-migratory activities. The purpose of this study is to evaluate the effect of andrographolide on proliferation and migration induced by growth factors (TGF-β and bFGF) in the lens epithelial cell line, FHL 124. We have also evaluated the role of the PI3K/Akt pathway and its alteration by andrographolide during proliferation and migration of lens epithelial cells. The results showed that andrographolide significantly inhibited proliferation in a dose and time dependent manner. The growth factors, TGF-β and bFGF, induced migration of lens epithelial cells, which was lowered by andrographolide. The growth factors also up regulated phosphorylated Akt (Ser473) and Akt (Thr308), which was abolished by simultaneous treatment of andrographolide. Similar changes were also observed with the PI3K inhibitor, LY290042. Our findings suggest that andrographolide reduces proliferation, migration, and phosphorylated Akt levels in lens epithelial cells. Hence andrographolide can be utilized for the prevention of PCO.

2015-05-01

Full Text Available Exposure to hazardous concentrations of volatile organic compounds indoors in small workshops could affect the health of workers, resulting in respirative diseases, severe intoxication or even cancer. Controlling the concentration of volatile organic compounds is required to prevent harmful conditions for workers in indoor environments. In this document, PI and fuzzy PI controllers were used to reduce hazardous indoor air benzene concentrations in small workplaces. The workshop is represented by means of a well-mixed room model. From the knowledge obtained from the model, PI and fuzzy PI controllers were designed and their performances were compared. Both controllers were able to maintain the benzene concentration within secure levels for the workers. The fuzzy PI controller performed more efficiently than the PI controller. Both approaches could be expanded to control multiple extractor fans in order to reduce the air pollution in a shorter time. The results from the comparative analysis showed that implementing a fuzzy logic PI controller is promising for assuring indoor air quality in this kind of hazardous work environment.

Pyrophosphate synthesis in iron mineral films and membranes simulating prebiotic submarine hydrothermal precipitates

Cells use three main ways of generating energy currency to drive metabolism: (i) conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) by the proton motive force through the rotor-stator ATP synthase; (ii) the synthesis of inorganic phosphate˜phosphate bonds via proton (or sodium) pyrophosphate synthase; or (iii) substrate-level phosphorylation through the direct donation from an active phosphoryl donor. A mechanism to produce a pyrophosphate bond as “energy currency” in prebiotic systems is one of the most important considerations for origin of life research. Baltscheffsky (1996) suggests that inorganic pyrophosphate (PO74-; PPi) may have preceded ATP/ADP as an energy storage molecule in earliest life, produced by an H+ pyrophosphatase. Here we test the hypothesis that PPi could be synthesized in inorganic precipitates simulating hydrothermal chimney structures transected by thermal and/or ionic gradients. Appreciable yields of PPi were obtained via substrate phosphorylation by acetyl phosphate within the iron sulfide/silicate precipitates at temperatures expected for an alkaline hydrothermal system. The formation of PPi only occurred in the solid phase, i.e. when both Pi and the phosphoryl donor were precipitated with Fe-sulfides or Fe-silicates. The amount of Ac-Pi incorporated into the precipitate was a significant factor in the amount of PPi that could form, and phosphate species were more effectively incorporated into the precipitate at higher temperatures (⩾50 to >85 °C). Thus, we expect that the hydrothermal precipitate would be more enriched in phosphate (and especially, Ac-Pi) near the inner margins of a hydrothermal mound where PPi formation would be at a maximum. Iron sulfide and iron silicate precipitates effectively stabilized Ac-Pi and PPi against hydrolysis (relative to hydrolysis in aqueous solution). Thus it is plausible that PPi could accumulate as an energy currency up to useful concentrations for early life in a

Full Text Available Purpose: To investigate the effect of JTXK granule on the expression pattern of miRNA in pancreatic tissue of KKAy diabetic mice, and to explore the molecular mechanism and pathways of JTXK granule in anti-diabetic effect.Methods: We used high fat diet (HFD to induce the KKAy diabetic mice and screened the differentially expressed miRNAs (DEMs between JTXK-treated group (n = 6 and the diabetic group (n = 6 using MicroRNA (miRNA Microarray. C57BL/6J mice were given a normal diet as the control group (n = 6. Subsequently, miRNA target gene prediction, GO and Pathway analysis were used to explore the function of DEMs. Finally, the mechanism of anti-diabetic effects of JTXK granule was tested by in vitro INS-1 pancreatic β-cell experiment.Results: The blood glucose and body weight of JTXK-treated group was significantly lower compared with the model group. Moreover, a total of 45 miRNAs with significant differences were detected in the model group and the JTXK-treated group (P ≤ 0.05, Fold Change > 2. Further, miRNA-mRNA analysis showed that the differential expression of mmu-miR-192-5p, mmu-miR-291a-3p, mmu-miR-320-3p, mmu-miR-139-5p and mmu-miR-378a-3p are closely related to pancreatic histological changes. In addition, pathway analysis showed that the DEMs were closely related to PI3K-Akt Signaling Pathway. Furthermore, the levels of serine/threonine-protein kinase (Akt, phosphorylated Akt (p-Akt and phosphorylated forkhead transcription factor O1 (p-Foxo1 in INS-1-FOXO1 overexpressing model cells were lower than those in normal group, while JTXK granules could increase the expression of Akt, p-Akt and p-Foxo1.Conclusions: The results showed that JTXK granule could play an anti-diabetic role by regulating the mRNA and miRNAs associated with PI3K-Akt pathway in diabetic mice pancreatic tissue.

Proton-proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{-1}$i, are analysed to search for the charmless ${B^0 \\to \\rho^0 \\rho^0}$ decay. More than 600 ${B^0 \\to (\\pi^+\\pi^-)(\\pi^+\\pi^-)}$ signal decays are selected and used to perform an amplitude analysis from which the ${B^0 \\to \\rho^0 \\rho^0}$ decay is observed for the first time with 7.1 standard deviations significance. The fraction of ${B^0 \\to \\rho^0 \\rho^0}$ decays yielding a longitudinally polarised final state is measured to be $fL = 0.745^{+0.048}_{-0.058} ({\\rm stat}) \\pm 0.034 ({\\rm syst})$. The ${B^0 \\to \\rho^0 \\rho^0}$ branching fraction, using the ${B^0 \\to \\phi K^*(892)^{0}}$ decay as reference, is also reported as $\\mathcal B (B^0 \\to \\rho^0 \\rho^0) = (0.94 \\pm 0.17 ({\\rm stat}) \\pm 0.09 ({\\rm syst}) \\pm 0.06 ({\\rm BF})) \\times 10^{-6}$.

Lodrup, A.; Pottegård, Anton; Hallas, J.

2014-01-01

Objective Antireflux surgery (ARS) has been suggested as an alternative to lifelong use of proton pump inhibitors (PPI) in reflux disease. Data from clinical trials on PPI use after ARS have been conflicting. We investigated PPI use after ARS in the general Danish population using nationwide...

First Observation of Charmed Resonances in the $\\Lambda^0_b \\to \\Lambda^+_c \\pi^- \\pi^+ \\pi^-$ Inclusive Decay and Measurement of Their Relative Branching Ratios at CDF

Energy Technology Data Exchange (ETDEWEB)

Barria, Patrizia [Univ. of Siena (Italy)

2012-01-01

We present the observation of the $\\Lambda^0_b$ decay into a $\\Lambda^+_c \\pi^- \\pi^+ \\pi^-$ final state, in $p\\bar{p}$ collisions at $\\sqrt{s}$ = 1:96 TeV. The data analyzed were collected by the CDF II detector at the Fermilab Tevatron collider, and correspond to 2:4 $fb^{-1}$ of integrated luminosity. We fit the invariant mass distribution of the reconstructed candidates to extract a signal yield of 848 $\\pm$ 93 $\\Lambda^0_b$ into $\\Lambda^+_c \\pi^- \\pi^+ \\pi^-$....

Amplitude Analysis of the Decay $D_s^+ \\to \\pi^+ \\pi^- \\pi^+$ in the Experiment E831/FOCUS

Energy Technology Data Exchange (ETDEWEB)

Schilithz, Anderson Correa; /Rio de Janeiro, CBPF

2005-01-01

We present in this thesis the Dalitz Plot analysis of the D{sub s}{sup +} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +} decay, with the data of the E831/FOCUS, that took data in 1996 and 1997. The masses and widhts of f{sub 0}(980) and f{sub 0}(1370) are free parametres of the fit on Dalitz Plot, objectiving to study in detail these resonances. After this analysis we present the Spectator Model study on the S wave in this decay. For this study we used the formalism developed by M. Svec [2] for scattering. We present the comparison between the Isobar Model, frequently used in Dalitz Plot analysis, and this formalism.

Diffractive dissociation of a {pi}{sup -} beam(190 GeV/c) on a proton target was measured at the COMPASS spectrometer. During a run in 2008, a large number of events with {pi}{sup -}{pi}{sup -}{pi}{sup +}{eta} in the final state was recorded. Partial wave analyses(PWA) of these data are being performed, concentrating on the kinematic domain of momentum transfer t' from 0.1 to 1.0 GeV{sup 2}/c{sup 2}. Subject of this thesis is the diffractive production of X from {pi}{sup -}p{yields}Xp with the subsequent decays X{yields}{pi}{sup -}f{sub 1} and f{sub 1}{yields}{pi}{sup -}{pi}{sup +}{eta}. Two different decays of the {eta} were selected: {eta}{yields}{pi}{sup -}{pi}{sup +}{pi}{sup 0}({gamma}{gamma}) and {eta}{yields}{gamma}{gamma}. A kinematic fitting routine was used to improve the data selection. In order to do the PWA, a Monte Carlo(MC) simulation is needed to account for the detector acceptance. In the mass-independent PWA the angular distributions of the real events are compared with the event distributions imposed on Monte Carlo(MC) events in order to determine the production amplitudes of different assumed partial waves in mass bins of 50 MeV/c{sup 2} of the invariant mass m{sub X} of X in the range 1.3 < m{sub X} < 3.0 GeV/c{sup 2}, by means of a maximum-likelihood-fit. Then a simplified mass-dependent fit of Breit-Wigner amplitudes has been applied to the distributions of production intensities as a function of m{sub X} in order to determine the contributions of known or presumed resonances. In the {pi}{sup -}f{sub 1} channel, we focus on the S, P and D wave i.e. orbital angular momentum L=0, 1, 2 between {pi}{sup -} and f{sub 1}. Significant intensity and phase motion are observed for the following J{sup PC}M{sup {epsilon}} combinations, where J, P, C, M and {epsilon} stand for the total angular momentum, parity and charge conjugation, total spin projection and reflectivity: 1{sup -+}1{sup +} (S wave), 1{sup ++}0{sup +} (P wave), 2{sup -+}0{sup +} (D

A model in which Q/sub 1/ and Q/sub 2/ resonance contributions add coherently to a Gaussian background is shown to reproduce the mass dependence of the Jsup(P)=1/sup +/K*..pi.. and rhoK partial waves in K/sup + -/p..-->..K/sup + -/..pi../sup +/..pi../sup -/p at 13 GeV/c. Through a fit to the data, the mass and total width for Q/sub 1/ are found to be m=1289+-3+-(25) MeV, GAMMA=150+-9(+-70) MeV and for Q/sub 2/, m=1404+-3(+-10) MeV, GAMMA=142+-4(+-15) MeV, where estimated systematic errors are given in parentheses. While a significant background is required for the 1/sup +/K*..pi.. system, none is needed for the 1/sup +/rhoK system.

Gomisin N Inhibits Melanogenesis through Regulating the PI3K/Akt and MAPK/ERK Signaling Pathways in Melanocytes

Full Text Available Gomisin N, one of the lignan compounds found in Schisandra chinensis has been shown to possess anti-oxidative, anti-tumorigenic, and anti-inflammatory activities in various studies. Here we report, for the first time, the anti-melenogenic efficacy of Gomisin N in mammalian cells as well as in zebrafish embryos. Gomisin N significantly reduced the melanin content without cellular toxicity. Although it was not capable of modulating the catalytic activity of mushroom tyrosinase in vitro, Gomisin N downregulated the expression levels of key proteins that function in melanogenesis. Gomisin N downregulated melanocortin 1 receptor (MC1R, adenylyl cyclase 2, microphthalmia-associated transcription factor (MITF, tyrosinase, tyrosinase-related protein-1 (TRP-1, and tyrosinase-related protein-2 (TRP-2. In addition, Gomisin N-treated Melan-A cells exhibited increased p-Akt and p-ERK levels, which implies that the activation of the PI3K/Akt and MAPK/ERK pathways may function to inhibit melanogenesis. We also validated that Gomisin N reduced melanin production by repressing the expression of MITF, tyrosinase, TRP-1, and TRP-2 in mouse and human cells as well as in developing zebrafish embryos. Collectively, we conclude that Gomisin N inhibits melanin synthesis by repressing the expression of MITF and melanogenic enzymes, probably through modulating the PI3K/Akt and MAPK/ERK pathways.

To observe the effect of anti-gingivitis IgY toothpaste in control of gingivitis and plaque. The study was a double-blind, randomized, parallel-controlled clinical trail with a total of 100 subjects who were divided into two groups, experimental group and control group. The subjects in experimental group used anti-gingivitis IgY toothpaste to brush twice daily for 3 minutes, and the subjects in control group used none anti-gingivitis IgY toothpaste. The examiner recorded GI, PI and BOP index of all subjects at the baseline, 6-weeks and 12-weeks. SPSS21.0 software package was used for statistical analysis. Twelve weeks later, there were significant differences in GI and BOP between the two groups. Yet no significant difference was found in PI. Anti-gingivitis IgY toothpaste is effective in control of gingivitis.

Here, the expression of F4/80 on the cell surface of murine macrophages was exploited to develop a novel imaging tracer that could visualize macrophages in vivo. The immunoreactive fraction and IC{sub 50} of anti-F4/80-A3-1, conjugated with diethylenetriaminepentaacetic acid (DTPA) and radiolabelled with {sup 111}In, were determined in vitro using murine bone marrow-derived macrophages. In vivo biodistribution studies were performed with {sup 111}In-anti-F4/80-A3-1 and isotype-matched control antibody {sup 111}In-rat IgG2b at 24 and 72 h post-injection (p.i.) in SCID/Beige mice bearing orthotopic MDA-MB-231 xenografts. In some studies mice were also treated with liposomal clodronate. Macrophage content in tissues was determined immunohistochemically. Micro-single photon emission computed tomography (SPECT)/CT images were also acquired. In vitro binding assays showed that {sup 111}In-anti-F4/80-A3-1 specifically binds F4/80 receptor-positive macrophages. The immunoreactivity of anti-F4/80-A3-1 was 75 % and IC{sub 50} was 0.58 nM. In vivo, injection of 10 or 100 μg {sup 111}In-anti-F4/80-A3-1 resulted in splenic uptake of 78 %ID/g and 31 %ID/g, respectively, and tumour uptake of 1.38 %ID/g and 4.08 %ID/g, respectively (72 h p.i.). Liposomal clodronate treatment reduced splenic uptake of 10 μg {sup 111}In-anti-F4/80-A3-1 from 248 %ID/g to 114 %ID/g and reduced {sup 111}In-anti-F4/80-A3-1 uptake in the liver and femur (24 h p.i.). Tracer retention in the blood and tumour uptake increased (24 h p.i.). Tumour uptake of {sup 111}In-anti-F4/80-A3-1 was visualized by microSPECT/CT. Macrophage density in the spleen and liver decreased in mice treated with liposomal clodronate. Uptake of {sup 111}In-rat IgG2b was lower in the spleen, liver and femur when compared to {sup 111}In-anti-F4/80-A3-1. Radiolabelled anti-F4/80-A3-1 antibodies specifically localize in tissues infiltrated by macrophages in mice and can be used to visualize tumours. The liver and spleen act as antigen

Long-lived mitochondrial (Mit) mutants of Caenorhabditis elegans utilize a novel metabolism.

The Caenorhabditis elegans mitochondrial (Mit) mutants have disrupted mitochondrial electron transport chain (ETC) functionality, yet, surprisingly, they are long lived. We have previously proposed that Mit mutants supplement their energy needs by exploiting alternate energy production pathways normally used by wild-type animals only when exposed to hypoxic conditions. We have also proposed that longevity in the Mit mutants arises as a property of their new metabolic state. If longevity does arise as a function of metabolic state, we would expect to find a common metabolic signature among these animals. To test these predictions, we established a novel approach monitoring the C. elegans exometabolism as a surrogate marker for internal metabolic events. Using HPLC-ultraviolet-based metabolomics and multivariate analyses, we show that long-lived clk-1(qm30) and isp-1(qm150) Mit mutants have a common metabolic profile that is distinct from that of aerobically cultured wild-type animals and, unexpectedly, wild-type animals cultured under severe oxygen deprivation. Moreover, we show that 2 short-lived mitochondrial ETC mutants, mev-1(kn1) and ucr-2.3(pk732), also share a common metabolic signature that is unique. We show that removal of soluble fumarate reductase unexpectedly increases health span in several genetically defined Mit mutants, identifying at least 1 alternate energy production pathway, malate dismutation, that is operative in these animals. Our study suggests long-lived, genetically specified Mit mutants employ a novel metabolism and that life span may well arise as a function of metabolic state.

This book documents the history of pi from the dawn of mathematical time to the present. One of the beauties of the literature on pi is that it allows for the inclusion of very modern, yet accessible, mathematics. The articles on pi collected herein include selections from the mathematical and computational literature over four millennia, a variety of historical studies on the cultural significance of the number, and an assortment of anecdotal, fanciful, and simply amusing pieces. For this new edition, the authors have updated the original material while adding new material of historical and cultural interest. There is a substantial exposition of the recent history of the computation of digits of pi, a discussion of the normality of the distribution of the digits, new translations of works by Viete and Huygen, as well as Kaplansky's never-before-published "Song of Pi." From the reviews of earlier editions: "Few mathematics books serve a wider potential readership than does a source book and this particular on...

Massachusetts Institute of Technology (MIT) partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce energy consumption by at least 30% as part of DOE’s Commercial Building Partnerships (CBP) Program.1 Lawrence Berkeley National Laboratory (LBNL) provided technical expertise in support of this DOE program. MIT is one of the U.S.’s foremost higher education institutions, occupying a campus that is nearly 100 years old, with a building floor area totaling more than 12 million square feet. The CBP project focused on improving the energy performance of two campus buildings, the Ray and Maria Stata Center (RMSC) and the Building W91 (BW91) data center. A key goal of the project was to identify energy saving measures that could be applied to other buildings both within MIT’s portfolio and at other higher education institutions. The CBP retrofits at MIT are projected to reduce energy consumption by approximately 48%, including a reduction of around 72% in RMSC lighting energy and a reduction of approximately 55% in RMSC server room HVAC energy. The energy efficiency measure (EEM) package proposed for the BW91 data center is expected to reduce heating, ventilation, and air-conditioning (HVAC) energy use by 30% to 50%, depending on the final air intake temperature that is established for the server racks. The RMSC, an iconic building designed by Frank Gehry, houses the Computer Science and Artificial Intelligence Laboratory, the Laboratory for Information and Decision Systems, and the Department of Linguistics and Philosophy.

Peripheral T-cell non-Hodgkin lymphoma (PTCL) are heterogeneous, rare, and aggressive diseases mostly incurable with current cell cycle therapies. Aurora kinases (AKs) are key regulators of mitosis that drive PTCL proliferation. Alisertib (AK inhibitor) has a response rate ∼30% in relapsed and refractory PTCL (SWOG1108). Since PTCL are derived from CD4 + /CD8 + cells, we hypothesized that Program Death Ligand-1 (PD-L1) expression is essential for uncontrolled proliferation. Combination of alisertib with PI3Kα (MLN1117) or pan-PI3K inhibition (PF-04691502) or vincristine (VCR) was highly synergistic in PTCL cells. Expression of PD-L1 relative to PD-1 is high in PTCL biopsies (∼9-fold higher) and cell lines. Combination of alisertib with pan-PI3K inhibition or VCR significantly reduced PD-L1, NF-κB expression and inhibited phosphorylation of AKT, ERK1/2 and AK with enhanced apoptosis. In a SCID PTCL xenograft mouse model, alisertib displayed high synergism with MLN1117. In a syngeneic PTCL mouse xenograft model alisertib demonstrated tumor growth inhibition (TGI) ∼30%, whilst anti-PD-L1 therapy alone was ineffective. Alisertib + anti-PD-L1 resulted in TGI >90% indicative of a synthetic lethal interaction. PF-04691502 + alisertib + anti-PD-L1 + VCR resulted in TGI 100%. Overall, mice tolerated the treatments well. Co-targeting AK, PI3K and PD-L1 is a rational and novel therapeutic strategy for PTCL.

The BABAR experiment operating at the PEP-II e{sup +}e{sup -} collider is designed to study CP violation effects in the B-meson system. From May 1999 to June 2002 approximately 81 fb{sup -1} of data have been collected at the {Upsilon}(4S) resonance, containing (87.9 {+-} 1.4) Million BB pairs. From this data sample the branching fraction for the decay B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0} has been extracted using a multi-dimensional maximum likelihood technique. With an efficiency of 20.4%, we find 36{sub -14-1}{sup +15+1} B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0} events and measure the branching fraction to be {Beta}(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) = (2.0{sub -0.8-0.2}{sup +0.9+0.3}) x 10{sup -6} where the first error is statistical and the second systematic. The statistical significance is 3.1{sigma} and we report an upper limit of {Beta}(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) < 3.6 x 10{sup -6} (90%CL). The results of the fit are confirmed using a simple cut based analysis technique.

The series of hybrid inorganic-organic solids T(Im){sub 2}[Ni(CN){sub 4}] with T=Fe, Co, Ni and Im=imidazole were prepared by soft chemical routes from aqueous solutions of the involved building units: imidazole, T{sup 2+} metal and the [Ni(CN){sub 4}]{sup 2-} anionic block. The obtained samples were characterized from infrared and UV-vis spectroscopies, and thermogravimetric, X-ray diffraction and magnetic measurements. Anhydrous solids which crystallize with a monoclinic unit cell, in the I2/a space group with four formula units per cell (Z=4) were obtained. Their crystal structure was solved ab initio from the recorded X-ray powder patterns and then refined by the Rietveld method. The metal T is found with octahedral coordination to four N ends of CN groups and two imidazole molecules while the inner Ni atom preserves its planar coordination. The system of layers remains stacked in an ordered 3D structure through dipole-dipole and {pi}-{pi} interactions between imidazole rings from neighboring layers. In this way, a pillared structure is achieved without requiring the coordination of both nitrogen atoms from imidazole ring. The recorded magnetic data indicate the occurrence of a predominant ferromagnetic interaction at low temperature for Co and Ni but not for Fe. Such magnetic ordering is more favorable for Ni with transition temperature of 14.67 K, which was ascribed to the relatively high polarizing power for this metal. Within the considered T metals, to nickel the highest electron-withdrawing ability corresponds and this leads to an increase for the metal-ligand electron clouds overlapping and to a stronger {pi}-{pi} attractive interaction, two factors that result into a higher magnetic ordering temperature. - Graphical Abstract: Magnetic ordering through the {pi}-{pi} interaction between the imidazole rings.

Cystic Fibrosis Transmembrane Conductance Regulator Attaches Tumor Suppressor PTEN to the Membrane and Promotes Anti Pseudomonas aeruginosa Immunity.

The tumor suppressor PTEN controls cell proliferation by regulating phosphatidylinositol-3-kinase (PI3K) activity, but the participation of PTEN in host defense against bacterial infection is less well understood. Anti-inflammatory PI3K-Akt signaling is suppressed in patients with cystic fibrosis (CF), a disease characterized by hyper-inflammatory responses to airway infection. We found that Ptenl -/- mice, which lack the NH 2 -amino terminal splice variant of PTEN, were unable to eradicate Pseudomonas aeruginosa from the airways and could not generate sufficient anti-inflammatory PI3K activity, similar to what is observed in CF. PTEN and the CF transmembrane conductance regulator (CFTR) interacted directly and this interaction was necessary to position PTEN at the membrane. CF patients under corrector-potentiator therapy, which enhances CFTR transport to the membrane, have increased PTEN amounts. These findings suggest that improved CFTR trafficking could enhance P. aeruginosa clearance from the CF airway by activating PTEN-mediated anti-bacterial responses and might represent a therapeutic strategy.

The analysis of this signal confirms the results obtained by the OBELIX Collaboration in previous works, namely: the existence of two pseudoscalar states at 1.413+or-0.002 and 1.460+or-0.012 GeV with widths 0.051+or-0.004 and 0.120+or-0.015 GeV, respectively. The pp system in the /sup 3/P/sub 1/ wave shows also a signal corresponding to the axial vector f/sub 1/ (1420) decaying to K*K with mass 1.420+or-0.003 GeV and width 0.061+or-0.005 GeV. A study of the incoherent phase space background shows that its origin is mostly due to the reflection of a resonant state in the K/sup +/K /sup -/ pi /sup +/ pi /sup -/ system. The isobar decomposition of this resonant state is mainly f/sub 0/(1370)( pi pi )/sub S/, its parame...

The reaction pi /sup -/p to omega n has been studied at 8 and 12 GeV/c incident momenta with the CERN Omega spectrometer using a neutron time of flight trigger. The differential cross sections and the omega - decay density matrix elements are presented as functions of the momentum transfer squared -t in the range of 0.02 to 0.80 GeV/sup 2/. The data are used to evaluate the intercept and slope of both the natural and unnatural parity exchange trajectories. Regge exchange amplitude factorisation tests involving the reaction pi N to omega N are investigated. (32 refs).

The decay {tau}{sup {minus}}{r_arrow}2{pi}{sup {minus}}{pi}{sup + }3{pi}{sup 0}{nu}{sub {tau}} has been studied with the CLEOII detector at the Cornell Electron Storage Ring. The branching fraction is measured to be (2.85{plus_minus}0.56{plus_minus}0.51){times}10{sup {minus}4} . The result is in good agreement with the isospin expectation but somewhat below the conserved-vector-current prediction. We have searched for resonance substructure in the decay. Within the statistical precision, the decay is saturated by the channels {tau}{sup {minus}}{r_arrow}{pi}{sup {minus}}2{pi}{sup 0 }{omega}{nu}{sub {tau}} , 2{pi}{sup {minus}}{pi}{sup +}{eta}{nu}{sub {tau}} , and {pi}{sup {minus}}2{pi}{sup 0}{eta}{nu}{sub {tau}} .

The LHCb experiment is designed to perform flavour physics measurements at the Large Hadron Collider. Using data collected during the 2010 run, we reconstructed a sample of $H_b \\to h^+h^{'-}$ decays, where $H_b$ can be either a $B^0$ meson, a $B^s_0$ meson or a $\\Lambda_b$ baryon, while h and $h^’$ stand for $\\pi$, K or p. Such decays are sensitive probes of the Cabibbo-Kobayashi-Maskawa matrix and have the potential to reveal the presence of New Physics. We present preliminary measurements of the direct CP asymmetries in the $B^0 \\to K^+\\pi^-$ and $B_s^0 \\to \\pi^+ K^-$ decays.

The use of Acoustic Radiation Force decorrelation-weighted pulse inversion (ADW-PI) for enhanced ultrasound contrast imaging

Objectives The use of ultrasound imaging for cancer diagnosis and screening can be enhanced with the use of molecularly targeted microbubbles. Nonlinear imaging strategies such as pulse inversion (PI) and “contrast pulse sequences” (CPS) can be used to differentiate microbubble signal, but often fail to suppress highly echogenic tissue interfaces. This failure results in false positive detection and potential misdiagnosis. In this study, a novel Acoustic Radiation Force (ARF) based approach was developed for superior microbubble signal detection. The feasibility of this technique, termed ARF-decorrelation-weighted PI (ADW-PI), was demonstrated in vivo using a subcutaneous mouse tumor model. Materials and Methods Tumors were implanted in the hindlimb of C57BL/6 mice by subcutaneous injection of MC38 cells. Lipid-shelled microbubbles were conjugated to anti-VEGFR2 antibody and administered via bolus injection. An image sequence using ARF pulses to generate microbubble motion was combined with PI imaging on a Verasonics Vantage programmable scanner. ADW-PI images were generated by combining PI images with inter-frame signal decorrelation data. For comparison, CPS images of the same mouse tumor were acquired using a Siemens Sequoia clinical scanner. Results Microbubble-bound regions in the tumor interior exhibited significantly higher signal decorrelation than static tissue (n = 9, p < 0.001). The application of ARF significantly increased microbubble signal decorrelation (n = 9, p < 0.01). Using these decorrelation measurements, ADW-PI imaging demonstrated significantly improved microbubble contrast-to-tissue ratio (CTR) when compared to corresponding CPS or PI images (n = 9, p < 0.001). CTR improved with ADW-PI by approximately 3 dB compared to PI images and 2 dB compared to CPS images. Conclusions Acoustic radiation force can be used to generate adherent microbubble signal decorrelation without microbubble bursting. When combined with pulse inversion

Here, the expression of F4/80 on the cell surface of murine macrophages was exploited to develop a novel imaging tracer that could visualize macrophages in vivo. The immunoreactive fraction and IC50 of anti-F4/80-A3-1, conjugated with diethylenetriaminepentaacetic acid (DTPA) and radiolabelled with (111)In, were determined in vitro using murine bone marrow-derived macrophages. In vivo biodistribution studies were performed with (111)In-anti-F4/80-A3-1 and isotype-matched control antibody (111)In-rat IgG2b at 24 and 72 h post-injection (p.i.) in SCID/Beige mice bearing orthotopic MDA-MB-231 xenografts. In some studies mice were also treated with liposomal clodronate. Macrophage content in tissues was determined immunohistochemically. Micro-single photon emission computed tomography (SPECT)/CT images were also acquired. In vitro binding assays showed that (111)In-anti-F4/80-A3-1 specifically binds F4/80 receptor-positive macrophages. The immunoreactivity of anti-F4/80-A3-1 was 75 % and IC50 was 0.58 nM. In vivo, injection of 10 or 100 μg (111)In-anti-F4/80-A3-1 resulted in splenic uptake of 78 %ID/g and 31 %ID/g, respectively, and tumour uptake of 1.38 %ID/g and 4.08 %ID/g, respectively (72 h p.i.). Liposomal clodronate treatment reduced splenic uptake of 10 μg (111)In-anti-F4/80-A3-1 from 248 %ID/g to 114 %ID/g and reduced (111)In-anti-F4/80-A3-1 uptake in the liver and femur (24 h p.i.). Tracer retention in the blood and tumour uptake increased (24 h p.i.). Tumour uptake of (111)In-anti-F4/80-A3-1 was visualized by microSPECT/CT. Macrophage density in the spleen and liver decreased in mice treated with liposomal clodronate. Uptake of (111)In-rat IgG2b was lower in the spleen, liver and femur when compared to (111)In-anti-F4/80-A3-1. Radiolabelled anti-F4/80-A3-1 antibodies specifically localize in tissues infiltrated by macrophages in mice and can be used to visualize tumours. The liver and spleen act as antigen sink organs for macrophage-specific tracers.

From May 1999 to June 2002 approximately 81 fb sup - sup 1 of data have been collected at the UPSILON(4S) resonance, containing (87.9 +- 1.4) Million BB pairs. From this data sample the branching fraction for the decay B sup 0 -> pi sup 0 pi sup 0 has been extracted using a multi-dimensional maximum likelihood technique.

Aim: The detection of TSH-receptor-antibodies (TRAb) in patients (pts) with Graves' disease (GD) is routinely used in nuclear medicine laboratories. It is performed by commercial, porcine radioreceptorassays (RRA) measuring TSH binding inhibitory activity. A second generation assay using the human, recombinant TSH-receptor was developed during the last years. The manufacturer composed this new assay as a coated tube RRA (CT RRA) and claimed a higher sensitivity for GD. Methods: TRAb was measured in 207 pts with various thyroid disorders and 205 healthy controls using the new coated tube RRA (Fa. B.R.A.H.M.S. Diagnostica GmbH, Berlin, Germany) as well as a conventional RRA (Fa. Medipan Diagnostica GmbH, Selchow, Germany): 60 pts suffering from GD showing a relapse after anti-thyroid drug treatment and before radioiodine therapy, 109 pts with disseminated autonomia (DA) and 38 pts suffering from Hashimoto's thyroiditis. A ROC-analysis was performed to find the optimal decision threshold level for positivity. Results: We found 42/60 TRAb-positive pts with GD in the established RRA (threshold 6 U/L) and 52/60 in the CT RRA, respectively. The sensitivity increased from 70% (RRA) to 86,7% (CT RRA). The CT RRA found 2 false positives (one Hashimoto's and one healthy control) and the RRA detected 3 Hashimoto's and 2 healthy controls as false positive. Conclusion: The increased sensitivity of CT RRA for GD provides an advantage compared to conventional RRA, especially in GD-patients relapsing afte antithyroid drug treatment. Functional sensitivity and Interassayvariation of CT RRA are very precisely compared to conventional RRA. Handling of the new assay is also improved. (orig.)

Full Text Available Der Islam mit seinen verschiedenen Verhaltensweisen und Verboten spielt direkt oder indirekt immer noch eine wichtige Rolle im alltäglichen Leben vieler Migranten. Religiöse Vorschriften zeichnen sich dadurch aus, dass ihrer Achtung nicht juristisch, sondern durch sozialen Druck Nachdruck verliehen wird (Verwandtschaft, religiöse Lehrer, islamische Gemeinde, religiöse Vereine etc. und dass ihre Missachtung mit Folgen in Form von Ausgrenzung, Missachtung und Diskriminierung einhergeht. Die kulturellen Vorstellungen der ersten Generation unterscheiden sich auf Grund der unterschiedlichen Biografien von denen der zweiten und dritten durch den Grad der Verwurzelung in der kulturellen Identität und der Verbundenheit mit traditionellen Wertvorstellungen. Fehlende Integrationskonzepte, Ausgrenzung im Migrationsland auf der einen und weltweite staatliche und halbstaatliche Konflikte im Namen des Islams bis hin zum Terrorismus auf der anderen Seite haben einen erheblichen Einfluss auf den Integrationsgrad von jugendlichen Migranten im Aufnahmeland.

The branching fractions for B{sup 0} --> K{sup 0}{pi}{sup +}{pi}{sup -}, B{sup 0} --> K*{sup +}{pi}{sup -} and B{sup 0} --> D{sup -}(--> K{sub s}{sup 0}{pi}{sup -}){pi}{sup +} decaying to a K{sub s}{sup 0}{pi}{sup +}{pi}{sup -} state have been measured and agree with previous measurements. The direct CP violating parameter A{sub K*{pi}} was measured for the decay B{sup 0} --> K*{sup +}{pi}{sup -} and is in agreement with the CLEO measurement, with no evidence of CP violation with the statistics used. Using larger datasets, one can extract amplitudes and relative phases of the resonant contributions to the Dalitz plot, with the possibility to observe new B-meson decays.

The decay $B^0_s \\to J/\\psi\\pi^+\\pi^-$ can be exploited to study $CP$ violation. A detailed understanding of its structure is imperative in order to optimize its usefulness. An analysis of this three-body final state is performed using a 1.0 fb$^{-1}$ sample of data produced in 7 TeV $pp$ collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis of the final state is performed using both the invariant mass spectra and the decay angular distributions. The $\\pi^+\\pi^-$ system is shown to be dominantly in an S-wave state, and the $CP$-odd fraction in this $B^0_s$ decay is shown to be greater than 0.977 at 95\\% confidence level. In addition, we report the first measurement of the $J/\\psi\\pi^+\\pi^-$ branching fraction relative to $J/\\psi\\phi$ of $(21.28 \\pm 0.51 \\pm 0.56)\\%$.

[Relations between FANS, PPI and atrial fibrillation].

Science.gov (United States)

Ricci, Fabrizio; De Caterina, Raffaele

2013-05-01

Recent evidence supports the existence of an association between the use of non-steroidal anti-inflammatory drugs and the risk of atrial fibrillation. Anti-inflammatory drugs are widely used for the treatment of systemic inflammatory disorders, and chronic inflammation is a well-known risk factor for the development of myocardial fibrosis. The latter accounts for atrial inhomogeneities of conduction, thus triggering and perpetuating atrial fibrillation. Atrial inflammatory remodeling may therefore be responsible for the higher incidence of atrial fibrillation among patients assuming steroidal and non-steroidal anti-inflammatory drugs because of an underlying inflammatory disorders. Alternative theories contemplate gastroesophageal reflux, which is extremely common during the use of non-steroidal anti-inflammatory drugs and may trigger atrial fibrillation, as mediating the above-mentioned association.

Association between PI3K/Akt/mTOR/p70S6K signaling pathway and hepatic fibrosis

Full Text Available Phosphoinositide 3-kinase (PI3K/protein kinase-B (AkT/mammalian target of rapamycin (mTOR/70-kDa ribosomal protein S6 kinase (p70S6K, PI3K/Akt/mTOR/p70S6K, is an important signaling pathway in the life activities of cells, and it plays an important role in promoting the growth, proliferation, invasion, and anti-apoptosis of cells and promoting angiogenesis. It was clarified that the PI3K/Akt/mTOR/p70S6K signaling pathway is involved in regulating the activities of hepatic stellate cell(HSC, thus influencing the development and progression of hepatic fibrosis. Analysis demonstrated that blocking any target of the PI3K/Akt/mTOR/p70S6K signaling pathway can inhibit the activation and proliferation of HSC, promote the apoptosis of HSC, inhibit the extracellular matrix secretion from HSC, and delay the progression of hepatic fibrosis. Blocking the pathway is expected to be a treatment strategy for hepatic fibrosis.

Hepatic stellate cells (HSCs) are the primary source of matrix components in liver disease such as fibrosis. Phosphatidylinositol 3-kinase (PI3K) signaling in HSCs has been shown to induce fibrogenesis. In this study, we evaluated the anti-fibrotic activity of a novel imidazopyridine analogue (HS-173) in human HSCs as well as mouse liver fibrosis. HS-173 strongly suppressed the growth and proliferation of HSCs and induced the arrest at the G2/M phase and apoptosis in HSCs. Furthermore, it reduced the expression of extracellular matrix components such as collagen type I, which was confirmed by an in vivo study. We also observed that HS-173 blocked the PI3K/Akt signaling pathway in vitro and in vivo. Taken together, HS-173 suppressed fibrotic responses such as cell proliferation and collagen synthesis by blocking PI3K/Akt signaling. Therefore, we suggest that this compound may be an effective therapeutic agent for ameliorating liver fibrosis through the inhibition of PI3K signaling. PMID:24326778

The MIT-Skywalker is a robotic device developed for the rehabilitation of gait and balance after a neurological injury. This device has been designed based on the concept of a passive walker and provides three distinct training modes: discrete movement, rhythmic movement, and balance training. In this paper, we present our efforts to evaluate the comfort of a bicycle/saddle seat design for the system's novel actuated body weight support device. We employed different bicycle and saddle seats and evaluated comfort using objective and subjective measures. Here we will summarize the results obtained from a study of fifteen healthy subjects and one stroke patient that led to the selection of a saddle seat design for the MIT-Skywalker.

Interpretation of CP violation measurements using charmonium decays, in both the B0 and Bs systems, can be subject to changes due to "penguin" type diagrams. These effects can be investigated using measurements of the Cabibbo-suppressed B0->J/\\psi pi+pi- decays. The final state composition of this channel is investigated using a 1.0/fb sample of data produced in 7 TeV pp collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis is performed using both the invariant mass spectra and the decay angular distributions. An improved measurement of the B0->J/\\psi pi+pi- branching fraction of (3.97 +/-0.09+/- 0.11 +/- 0.16)x10^{-5} is reported where the first uncertainty is statistical, the second is systematic and the third is due to the uncertainty of the branching fraction of the decay B- -> J/\\psi K- used as a normalization channel. In the J/\\psi pi+pi- final state significant production of f0(500) and rho(770) resonances is found, both of which can be used for CP violation studie...

Prism plot analysis of the reaction positive Pi+ P → P Pi+ Pi0 at 4.1 GeV/C

International Nuclear Information System (INIS)

Heller, M.E.

1980-01-01

A sample of events fit to the reaction pi + p → p pi + pi 0 and extracted from exposures of a hydrogen bubble chamber to 4.09 GeV/c positive pions, has been separated into its channels by the method of prism plot tagging. Background affecting the reaction has been removed by the same method. The separated channels have been studied, and the dominant resonances fit with the Dual Absorptive Model. The delta+ + is found to be consistent with that extracted from higher-momentum data by conventional means, and is well fit by the model, using rho exchange. The rho + is well fit by an extended parameterization of the model at all but the lowest momentum transfers. Omega-meson exchange is indicated as the dominant mechanism for the reaction pi + p → rho + for momentum transfers greater than 0.02 GeV 2 /c 2 ; pion exchange is suggested as the probable mechanism at lower momentum transfers

To explore the effect of quercetin on the proliferation and apoptosis of HeLa cells, HeLa cells were incubated with quercetin at different concentrations. Cell viability was evaluated by MTT assay, cell apoptosis was detected by Annexin-V/PI double labeled cytometry and DNA ladder assay. Cell cycle was flow cytometrically determined and the morphological changes of the cells were observed under a fluorescence microscope after Hoechst 33258 staining and the apoptosis-related proteins in the HeLa cells were assessed by Western blotting. The results showed that quercetin significantly inhibited the growth of HeLa cells and induced obvious apoptosis in vitro in a time- and dose-dependent manner. Moreover, quercetin induced apoptosis of HeLa cells in cell cycle-dependent manner because quercetin could induce arrest of HeLa cells at G0/G1 phase. Quercetin treatment down-regulated the expression of the PI3K and p-Akt. In addition, quercetin could down-regulate expression of bcl-2, up-regulate Bax, but exerted no effect on the overall expression of Akt. We are led to conclude that quercetin induces apoptosis via PI3k/Akt pathways, and quercetin has potential to be used as an anti-tumor agent against human cervix cancer.

We present a study on the invariant mass distribution of {pi}''{+-}{pi}''0 pairs produced in the process {tau}{yields}{pi}''{+-}{pi}''0{nu} . The analysis is based on a sample of 33,096 events collected by the L3 detector between 1991 and 1994. The data is not inconsistent with the hypothesis that the process is being mediated by the p(770) meson alone but is in better agreement with the inclusion of an extra {rho} resonance in the decay of the tau lepton.

A search for non-resonant $D^{+}_{(s)} \\rightarrow \\pi^{+} \\mu^{+} \\mu^{-}$ and $D^{+}_{(s)} \\rightarrow \\pi^{-} \\mu^{+} \\mu^{+}$ decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, at $\\sqrt{s}=7$ TeV recorded by the LHCb experiment in 2011. No signals are observed and the $90\\% \\, (95\\%)$ confidence level (CL) limits on the branching fractions are found to be \\begin{eqnarray*} \\mathcal{B}(D^{+} \\rightarrow \\pi^{+} \\mu^{+} \\mu^{-}) < 7.3 \\, (8.3) \\times 10^{-8},\\\\ \\mathcal{B}(D^{+}_{s} \\rightarrow \\pi^{+} \\mu^{+} \\mu^{-}) < 4.1 \\, (4.8) \\times 10^{-7},\\\\ \\mathcal{B}(D^{+} \\rightarrow \\pi^{-} \\mu^{+} \\mu^{+}) < 2.2 \\, (2.5) \\times 10^{-8},\\\\ \\mathcal{B}(D^{+}_{s} \\rightarrow \\pi^{-} \\mu^{+} \\mu^{+}) < 1.2 \\, (1.4) \\times 10^{-7}.\\\\ \\end{eqnarray*} These limits are the most stringent to date.

A search for the rare decays $B_s^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ and $B^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ is performed in a data set corresponding to an integrated luminosity of 3.0 fb$^{-1}$ collected by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. Decay candidates with pion pairs that have invariant mass in the range 0.5-1.3 GeV/$c^2$ and with muon pairs that do not originate from a resonance are considered. The first observation of the decay $B_s^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ and the first evidence of the decay $B^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-$ are obtained and the branching fractions are measured to be $\\mathcal{B}(B_s^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-)=(8.6\\pm 1.5\\,({\\rm stat}) \\pm 0.7\\,({\\rm syst})\\pm 0.7\\,({\\rm norm}))\\times 10^{-8}$ and $\\mathcal{B}(B^0 \\to \\pi^+\\pi^-\\mu^+\\mu^-)=(2.11\\pm 0.51\\,({\\rm stat}) \\pm 0.15\\,({\\rm syst})\\pm 0.16\\,({\\rm norm}) )\\times 10^{-8}$, where the third uncertainty is due to the branching fraction of the decay $B^0\\to J/\\psi(\\to \\mu^+\\mu^-)K^*(890)...

Full Text Available Ziel: Diese nichtinterventionelle Beobachtungsstudie (NIS wurde von Schweizer Gynäkologen und Allgemeinmedizinern im Rahmen der üblichen ärztlichen Grundversorgung durchgeführt. Das Ziel der NIS war es, die Wirksamkeit und Sicherheit von Vitex-agnus-castus-(VAC Extrakt (Ze 440: premens, Zeller Medical AG, Romanshorn, Schweiz bei Frauen, die unter menstruellen Zyklusstörungen wie Polymenorrhö, Oligomenorrhö oder Amenorrhö litten, zu untersuchen. Methode: Insgesamt 211 Patientinnen nahmen an dieser NIS teil. Symptome, die mit menstruellen Zyklusstörungen („menstrual cycle irregularities“ [MCIs] und der Menstruationsblutung in Verbindung stehen, wurden bei einer Erstuntersuchung („baseline visit“ [BV] und einer Kontrolluntersuchung („follow-up visit“ [FV] nach Behandlung mit VAC-Extrakt über einen Zeitraum von 3 aufeinanderfolgenden Menstruationszyklen beurteilt. Ergebnisse: Der Anteil der Patientinnen, bei denen eine Beschwerdefreiheit oder eine Besserung der MCIs (insgesamt und spezifischer Beschwerdebilder wie Polymenorrhö, Oligomenorrhö und Amenorrhö erzielt werden konnte, lag bei der FV bei 79–85 %. Bei Symptomen im Zusammenhang mit der Menstruationsblutung wie Dysmenorrhö, Zwischenblutungen, Hypermenorrhö, Menometrorrhagie, Ovulationsblutung, präoder postmenstrueller Blutung betrug der Anteil der Patientinnen, bei denen ein Rückgang oder eine Besserung festgestellt wurde, bei der FV zwischen 60 und 88 %. Von 53 Patientinnen, die bei der BV von einem unerfüllten Kinderwunsch berichteten, wurden 12 Frauen (23 % während der Behandlung mit VAC-Extrakt schwanger. Bei der FV waren 91 % der Ärzte und 92 % der Patientinnen mit den erzielten Behandlungsergebnissen „zufrieden“ oder „sehr zufrieden“ und 80 % der Patientinnen bestätigten, dass sie gerne mit der Behandlung mit VAC-Extrakt fortfahren wollen. Fazit: Diese Beobachtungsstudie im Bereich der ärztlichen Grundversorgung ergab, dass die Behandlung mit VAC

Iron (Fe) is an essential micronutrient for plant growth and development, and its reduced bioavailability strongly impairs mitochondrial functionality. In this work, the metabolic adjustment in the rice (Oryza sativa) mitochondrial Fe transporter knockdown mutant (mit-2) was analysed. Biochemical characterization of purified mitochondria from rice roots showed alteration in the respiratory chain of mit-2 compared with wild-type (WT) plants. In particular, proteins belonging to the type II alternative NAD(P)H dehydrogenases accumulated strongly in mit-2 plants, indicating that alternative pathways were activated to keep the respiratory chain working. Additionally, large-scale changes in the transcriptome and metabolome were observed in mit-2 rice plants. In particular, a strong alteration (up-/down-regulation) in the expression of genes encoding enzymes of both primary and secondary metabolism was found in mutant plants. This was reflected by changes in the metabolic profiles in both roots and shoots of mit-2 plants. Significant alterations in the levels of amino acids belonging to the aspartic acid-related pathways (aspartic acid, lysine, and threonine in roots, and aspartic acid and ornithine in shoots) were found that are strictly connected to the Krebs cycle. Furthermore, some metabolites (e.g. pyruvic acid, fumaric acid, ornithine, and oligosaccharides of the raffinose family) accumulated only in the shoot of mit-2 plants, indicating possible hypoxic responses. These findings suggest that the induction of local Fe deficiency in the mitochondrial compartment of mit-2 plants differentially affects the transcript as well as the metabolic profiles in root and shoot tissues. © The Author 2015.
