    Full Text Available Aromatic amines are an important group of industrial chemicals, which are widely used for manufacturing of dyes, pesticides, drugs, pigments, and other industrial products. These compounds have been considered highly toxic to human beings due to their carcinogenic nature. Three groups of aromatic amines have been recognized: monocyclic, polycyclic and heterocyclic aromatic amines. Bacterial degradation of several monocyclic aromatic compounds has been studied in a variety of bacteria, which utilizes monocyclic aromatic amines as their sole source of carbon and energy. Several degradation pathways have been proposed and the related enzymes and genes have also been characterized. Many reviews have been reviewed toxicity of monocyclic aromatic amines; however, there is lack of review on biodegradation of monocyclic aromatic amines. The aim of this review is to summarize bacterial degradation of monocyclic aromatic amines. This review will increase our current understanding of biochemical and molecular basis of bacterial degradation of monocyclic aromatic amines.

    2014-01-01

    Full Text Available A novel ultra-wideband (UWB monocycle pulse generator with good performance is designed and demonstrated in this paper. It contains a power supply circuit, a pulse drive circuit, a unique pulse forming circuit, and a novel monopolar-to-monocycle pulse transition circuit. The drive circuit employs wideband bipolar junction transistors (BJTs and linear power amplifier transistor to produce a high amplitude drive pulse, and the pulse forming circuit uses the transition characteristics of step recovery diode (SRD effectively to produce a negative narrow pulse. At last, the monocycle pulse forming circuit utilizes a novel inductance L short-circuited stub to generate the monocycle pulse directly. Measurement results show that the waveform of the generated monocycle pulses is over 76 V in peak-to-peak amplitude and 3.2 ns in pulse full-width. These characteristics of the monocycle pulse are advantageous for obtaining long detection range and high resolution, when it is applied to ultra-wideband radar applications.

    2014-01-01

    Background The enumeration of chemical graphs (molecular graphs) satisfying given constraints is one of the fundamental problems in chemoinformatics and bioinformatics because it leads to a variety of useful applications including structure determination and development of novel chemical compounds. Results We consider the problem of enumerating chemical graphs with monocyclic structure (a graph structure that contains exactly one cycle) from a given set of feature vectors, where a feature vector represents the frequency of the prescribed paths in a chemical compound to be constructed and the set is specified by a pair of upper and lower feature vectors. To enumerate all tree-like (acyclic) chemical graphs from a given set of feature vectors, Shimizu et al. and Suzuki et al. proposed efficient branch-and-bound algorithms based on a fast tree enumeration algorithm. In this study, we devise a novel method for extending these algorithms to enumeration of chemical graphs with monocyclic structure by designing a fast algorithm for testing uniqueness. The results of computational experiments reveal that the computational efficiency of the new algorithm is as good as those for enumeration of tree-like chemical compounds. Conclusions We succeed in expanding the class of chemical graphs that are able to be enumerated efficiently. PMID:24955135

    2016-06-01

    The global atmospheric budget and distribution of monocyclic aromatic compounds is estimated, using an atmospheric chemistry general circulation model. Simulation results are evaluated with an ensemble of surface and aircraft observations with the goal of understanding emission, production and removal of these compounds.Anthropogenic emissions provided by the RCP database represent the largest source of aromatics in the model (≃ 23 TgC year-1) and biomass burning from the GFAS inventory the second largest (≃ 5 TgC year-1). The simulated chemical production of aromatics accounts for ≃ 5 TgC year-1. The atmospheric burden of aromatics sums up to 0.3 TgC. The main removal process of aromatics is photochemical decomposition (≃ 27 TgC year-1), while wet and dry deposition are responsible for a removal of ≃ 4 TgC year-1.Simulated mixing ratios at the surface and elsewhere in the troposphere show good spatial and temporal agreement with the observations for benzene, although the model generally underestimates mixing ratios. Toluene is generally well reproduced by the model at the surface, but mixing ratios in the free troposphere are underestimated. Finally, larger discrepancies are found for xylenes: surface mixing ratios are not only overestimated but also a low temporal correlation is found with respect to in situ observations.

    Yamashita, Mikio; Morita, Ryuji

    2005-01-01

    "Mono-Cycle Photonics and Optical Scanning Tunneling Microscopy" deals with both the ultrashort laser-pulse technology in the few- to mono-cycle region and the laser-surface-controlled scanning-tunneling microscopy (STM) extending into the spatiotemporal extreme technology. The former covers the theory of nonlinear pulse propagation beyond the slowly-varing-envelope approximation, the generation and active chirp compensation of ultrabroadband optical pulses, the amplitude and phase characterization of few- to mono-cycle pulses, and the feedback field control for the mono-cycle-like pulse generation. In addition, the wavelength-multiplex shaping of ultrabroadband pulse is described. The latter covers the CW-laser-excitation STM, the femtosecond-time-resolved STM and atomic-level surface phenomena controlled by femtosecond pulses.

    1978-01-01

    The antiviral compound trisodium phosphonoformate (PFA), which inhibits herpesvirus multiplication by 50% at a concentration of 10 μM, did not show any effects on macromolecular synthesis and cell proliferation in HeLa and human lung cells at this concentration. At the high concentration of 2 mM, PFA reduced DNA synthesis to 50% after 1 h of treatment, whereas no effects could be seen on RNA and protein synthesis. Treatment for 24 h with 1 mM PFA inhibited both DNA synthesis and cell proliferation to 50%. The inhibition of DNA synthesis and cell proliferation at 10 mM PFA was rapidly reversed by removing the drug from the cells. PMID:727763

    2010-09-01

    Full Text Available Context Caroli’s disease is a rare congenital disorder first described by Caroli in 1958. This abnormality consists of non-obstructive, saccular or fusiform dilation of the intrahepatic bile ducts resulting in cystic lesions; similar abnormalities may also occur in the kidneys and pancreas. Case report We illustrate the role of enhanced mangafodipir trisodium magnetic resonance imaging in a patient with sporadic non-hereditary Caroli’s disease associated with pancreatic involvement in which mangafodipir trisodium magnetic resonance imaging characterized part of the cystic liver lesions as saccular dilations of the intrahepatic bile ducts of the left lobe, allowing diagnosis of the disease. Conclusion We strongly recommend hepatobiliary magnetic resonance imaging with mangafodipir trisodium in such patients.

    Mangafodipir trisodium (Teslascan), a hepatobiliary contrast agent, has the potential of providing functional biliary imaging similar to hepatobiliary scintigraphy. To our knowledge. the potential role of this biliary contrast agent in the detection of bile duct leaks has not been reported. In this case report, we report the first case of a bile duct leak diagnosed with enhanced MRI with mangafodipir trisodium in a patient following laparoscopic cholecystectomy. Our case illustrates that functional MR cholangiography images can be successfully acquired by using a post-mangafodipir fat-suppressed GRE technique and that bile duct leaks can be detected.

    We propose and experimentally demonstrate a scheme to simultaneously realize multi-channel centimeter wave (CMW) band and millimeter wave (MMW) band ultra-wideband (UWB) monocycle pulse generation using four wave mixing (FWM) effect in a highly nonlinear photonic crystal fiber (HNL-PCF). Two lightwaves carrying polarity-reversed optical Gaussian pulses with appropriate time delay and another lightwave carrying a 20 GHz clock signal are launched into the HNL-PCF together. By filtering out the FWM idlers, two CMW-band UWB monocycle signals and two MMW-band UWB monocycle signals at 20 GHz are obtained simultaneously. Experimental measurements of the generated UWB monocycle pulses at individual wavelength, which comply with the FCC regulations, verify the feasibility and flexibility of proposed scheme for use in practical UWB communication systems.

  1. Towards endometriosis diagnosis by gadofosveset-trisodium enhanced magnetic resonance imaging.

    Directory of Open Access Journals (Sweden)

    Marc H Schreinemacher

    Full Text Available Endometriosis is defined as the presence of endometrial tissue outside the uterus. It affects 10-15% of women during reproductive age and has a big personal and social impact due to chronic pelvic pain, subfertility, loss of work-hours and medical costs. Such conditions are exacerbated by the fact that the correct diagnosis is made as late as 8-11 years after symptom presentation. This is due to the lack of a reliable non-invasive diagnostic test and the fact that the reference diagnostic standard is laparoscopy (invasive, expensive and not without risks. High-molecular weight gadofosveset-trisodium is used as contrast agent in Magnetic Resonance Imaging (MRI. Since it extravasates from hyperpermeable vessels more easily than from mature blood vessels, this contrast agent detects angiogenesis efficiently. Endometriosis has high angiogenic activity. Therefore, we have tested the possibility to detect endometriosis non-invasively using Dynamic Contrast-Enhanced MRI (DCE-MRI and gadofosveset-trisodium as a contrast agent in a mouse model. Endometriotic lesions were surgically induced in nine mice by autologous transplantation. Three weeks after lesion induction, mice were scanned by DCE-MRI. Dynamic image analysis showed that the rates of uptake (inwash, persistence and outwash of the contrast agent were different between endometriosis and control tissues (large blood vessels and back muscle. Due to the extensive angiogenesis in induced lesions, the contrast agent persisted longer in endometriotic than control tissues, thus enhancing the MRI signal intensity. DCE-MRI was repeated five weeks after lesion induction, and contrast enhancement was similar to that observed three weeks after endometriosis induction. The endothelial-cell marker CD31 and the pericyte marker α-smooth-muscle-actin (mature vessels were detected with immunohistochemistry and confirmed that endometriotic lesions had significantly higher prevalence of new vessels (CD31 only

    Aim: Imaging of the left atrium is regularly performed prior to pulmonary vein isolation. The aim of the study was to evaluate the feasibility of contrast-enhanced high-resolution magnetic resonance angiography (MRA) of the left atrium using the blood-pool contrast agent gadofosveset trisodium in comparison to noncontrast MRA. Materials and methods: Twenty consecutive patients were examined by free-breathing electrocardiogram-gated whole-heart MRA (reconstructed spatial resolution, 0.7 mm x 0.6 mm x 0.8 mm) with a noncontrast T2-prepared steady state free precession sequence (T2-prep SSFP) and a gadofosveset trisodium-enhanced inversion-recovery SSFP sequence (CE IR-SSFP). Contrast-to-noise ratio (CNR) of blood in the left atrium was determined. Depiction of the left atrium was rated by two radiologists in consensus. A cardiologist segmented the MR data sets and rated depiction of the left atrium. Results: Five of 20 patients had irregular breathing patterns with navigator efficiency less than 35% and were excluded from evaluation. CNR was significantly higher for CE IR-SSFP compared with T2-prep SSFP (18.4 {+-} 5.3 vs. 11.7 {+-} 3.5, p < 0.01). Depiction of the left atrium by T2-prep SSFP was rated as good in four patients, moderate in ten patients, and poor in one patient, whereas depiction of the left atrium by CE IR-SSFP was rated as excellent in nine patients, good in four patients, and moderate in two patients. CE IR-SSFP allowed for semiautomated segmentation of the left atrium in 15 patients, whereas T2-prep SSFP allowed for segmentation only in ten patients. Conclusion: Gadofosveset trisodium-enhanced MRA of the left atrium is feasible with significantly improved image quality compared to noncontrast MRA.

    Full Text Available Novel esters of γ-aminobutyric acid (GABA with monocyclic terpenes were synthesized via Steglich esterification and characterized by 1H-NMR, IR and mass spectral studies. Their anticonvulsant, analgesic and anti-inflammatory activities were evaluated by a PTZ-induced convulsion model, AITC-induced hyperalgesia and AITC-induced paw edema, respectively. All studied esters, as well as their parent terpenes, were found to produce antinociceptive effects in the AITC-induced model and attenuate acute pain more than the reference drug benzocaine after their topical application. GABA esters of l-menthol and thymol were also shown to exceed the reference drug ibuprofen in their ability to decrease the inflammatory state induced by intraplantar injection of the TRPA1 activator AITC. The present findings indicate that GABA esters of carvacrol and guaiacol are not a classical prodrug and possess their own pharmacological activity. Prolonged antiseizure action of the ester based on the amino acid and guaiacol (200 mg/kg was revealed at 24 h after oral administration. Furthermore, orally co-administered gidazepam (1 mg/kg and GABA esters of l-menthol, thymol and carvacrol produce synergistic seizure prevention effects.

    Optical vortex, possessing an annular intensity profile and an orbital angular momentum (characterized by an integer termed a topological charge) associated with a helical wavefront, has attracted great attention for diverse applications due to its unique properties. In particular for terahertz (THz) frequency range, several approaches for THz vortex generation, including molded phase plates consisting of metal slit antennas, achromatic polarization elements and binary-diffractive optical elements, have been recently proposed, however, they are typically designed for a specific frequency. Here, we demonstrate highly intense broadband monocycle vortex generation near 0.6 THz by utilizing a polymeric Tsurupica spiral phase plate in combination with tilted-pulse-front optical rectification in a prism-cut LiNbO3 crystal. A maximum peak power of 2.3 MW was obtained for THz vortex output with an expected topological charge of 1.15. Furthermore, we applied the highly intense THz vortex beam for studying unique nonlinear behaviors in bilayer graphene towards the development of nonlinear super-resolution THz microscopy and imaging system.

    2004-10-01

    Factors influencing production of the monocyclic carotenoid torulene in recombinant Escherichia coli were investigated by modulating enzyme expression level, culture conditions, and engineering of the isoprenoid precursor pathway. The gene dosage of in vitro evolved lycopene cyclase crtY2 significantly changed the carotenoid profile. A culture temperature of 28 degrees C showed better production of torulene than 37 degrees C while initial culture pH had no significant effect on torulene production. Glucose-containing LB, 2xYT, TB and MR media significantly repressed the production of torulene, and the other carotenoids lycopene, tetradehydrolycopene, and beta-carotene, in E. coli. In contrast, glycerol-containing LB, 2xYT, TB, and MR media enhanced torulene production. Overexpression of dxs, dxr, idi and/or ispA, individually and combinatorially, enhanced torulene production up to 3.1-3.3 fold. High torulene production was observed in a high dissolved oxygen level bioreactor in TB and MR media containing glycerol. Lycopene was efficiently converted into torulene during aerobic cultures, indicating that the engineered torulene synthesis pathway is well coordinated, and maintains the functionality and integrity of the carotenogenic enzyme complex.

    In order to overcome the elementary heterogeneous nucleation while octahydro trisodium salt of fructose-1,6-diphosphate(FDPNaa.8 H2O) is crystallized with ethanol precipitation at low temperature, a new crystallizationmethod with alcohol precipitation combined with salt precipitation has been presented. The ethanol-sodium ac-etate system for crystallization of salt of fructose-1,6-diphosphate is based on the mechanism of crystallization ofFDPNa3.8 H2O in the ethanol-low temperature system. It is found that crystal size may be controlled by regulatingtemperature or pH value of solution in the crystallization process, and the crystal yield increases to 95% from 78%which obtained in the ethanol-low temperature system.

    Full Text Available Zinc sulfide (ZnS thin films due to their properties are widely used in various electronic optical devices. They are produced by several methods, among which – vacuum sublimation, high frequency sputtering method, quasiclosed volume method, sol-gel method, electrodeposition. These methods have high energy consumption which increases the price of ZnS thin films. Aim: The aim of this work is to establish the optimal parameters of the synthesis of ZnS thin films of the aqueous caustic and the correlation between content of zinc in the synthesized films determined by the method of stripping voltammetry and thickness, structural, morphological and optical parameters. Materials and Methods: The ZnS thin films were obtained from aqueous caustics of zinc-containing salt using chemical deposition. Fresh solution of zinc-containing salt, trisodium citrate (Na3C6H5O7 as a complexing agent, thiourea ((NH22CS and ammonium hydroxide (NH4OH was used for the synthesis of ZnS films by chemical deposition. The deposition was performed on prepared glass substrates with the area of 5,76 cm2. Results: The phase mixture of the films has been determined. It showed the presence of ZnS compounds in the cubic modification (sphalerite. Stripping voltammetry was used to determine the mass of zinc in the ZnS films on various conditions of synthesis, namely on the concentration of the initial zinc-containing salt, trisodium citrate, thiourea, deposition time and temperature. The surface morphology, optical properties, the thickness of the ZnS resulting films have been studied. Conclusions: The optimal conditions for the synthesis of ZnS films were found based on these data. Three-dimensional surface morphology of ZnS film studies showed its smoothness, uniformity, integrity and confirmed the correctness of determining the optimal synthesis parameters.

    Graphical abstract: - Highlights: • SnS thin films grown by CBD in different concentration of tri-sodium citrate. • Grain size increases, while surface roughness decreases, with concentration. • Optical band gap decreases from 1.40 eV to 1.17 eV with increasing concentration. • Electrical conductivity improves with increasing concentration. - Abstract: Tin sulfide thin films were deposited onto glass substrates by chemical bath deposition. The effects of molar concentration of the complexing agent, tri-sodium citrate, on the structural, morphological, optical and electrical properties of the films were investigated. The films are characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, optical absorption spectroscopy and Hall effect measurements. Polycrystalline film structure in orthorhombic phase was determined. Flower-like spherical grains are observed on the surface. While their average size increased from 345 nm to 750 nm when the tri-sodium citrate concentration was increased from 6.4 × 10{sup −3} M to 8.0 × 10{sup −3} M, the surface roughness varied in an opposite manner from approximately 120.18 nm to 29.36 nm. For these concentrations, optical band gap of the films decreased from 1.40 eV to 1.17 eV, whereas the Hall conductivity, mobility and carrier concentration of the films increased slightly from 5.91 × 10{sup −5} to 8.78 × 10{sup −5} (Ω cm){sup −1}, from 148 to 228 cm{sup 2} V{sup −1} s{sup −1} and from 1.73 × 10{sup 12} to 3.59 × 10{sup 12} cm{sup −1}, respectively.

    The synergy effect of trisodium phosphate (TSP) and ethanol against murine norovirus 1 (MNV-1), as a surrogate for human noroviruses, on fresh produces was evaluated. More than 2% (w/v) of TSP effectively inactivated MNV-1. The single treatment of 1% TSP or 30% ethanol for 30 min was not effective on MNV-1; however, cotreatment showed inactivation of MNV-1 on stainless steel and the produces of lettuce and bell pepper under 15 min. The results suggest that cotreatment of TSP and ethanol at a low concentration and a short time of exposure might be useful for the reduction of norovirus in some produce.

    Effect of trisodium citrate on the precipitation of carbonate apatite is studied. The experimental series are performed in the solution of artificial urine. The investigations are related to infectious urinary stones formation as carbonate apatite is one of the main components of this kind of stones. To mimic a real infection in urinary tract the aqueous ammonia solution was added to the solution of artificial urine. The spectrophotometric results demonstrate that trisodium citrate increases induction time with respect to carbonate apatite formation and decreases the efficiency of carbonate apatite precipitation. The inhibitory effect of trisodium citrate on the precipitation of carbonate apatite is explained in base of chemical speciation analysis. Such an analysis demonstrates that the inhibitory effect is mainly related with the fact that trisodium citrate binds Ca{sup 2+} ions and causes the formation of CaCit{sup −} and Ca{sub 10}(PO{sub 4}){sub 6}CO{sub 3} complexes. Trisodium citrate binds Ca{sup 2+} ions in the range of pH from 6 to 9.5 for which carbonate apatite is favored to be formed. - Highlights: • Trisodium citrate (TC) increases induction time of carbonate apatite (CA) formation. • TC decreases the efficiency of CA precipitation. • The inhibitory effect of TC is explained in base of chemical speciation analysis. • The inhibitory effect is mainly related with the fact that TC binds Ca{sup 2+} ions. • TC binds Ca{sup 2+} ions in the range of pH from 6 to 9.5 for which CA is formed.

    By simultaneous sequential sampling of gas and rainwater from 1999 to 2000 in the campus of Kanagawa University in Yokohama, Japan, we investigated the wet-scavenging process of volatile organic compounds, some chlorinated hydrocarbons (CHs) and monocyclic aromatic hydrocarbons (MAHs), via rain droplets. Their volume-weighted mean concentrations in 125 rainwater were 4.98 nM for dichloromethane, 3.71 nM for toluene, 2.00 nM for benzene, 0.93 nM for 1,2-dichloroethane, 0.62 nM for o-xylene, 0.57 nM for m, p-xylene, 0.51 nM for p-dichlorobenzene, and 0.35 nM for trichloromethylene. Their rainwater concentrations did not depend on the rainfall intensity, and the temporal variation of their concentrations was similar to that of gas-phase concentrations. The dissolution of CHs and MAHs into rainwater, however, was larger than expected from their gas-phase concentrations at the ground and their temperature-corrected Henry's law constants. A simple below-cloud scavenging model, which was developed by Levine and Schwartz (Atmos. Environ. 16 (1982) 1725) could explain the independence of the rainfall intensity but not explain their enhanced dissolution in rainwater. The results of this study indicate the estimated concentrations, which were based on the Henry's law equilibrium, considerably underestimate the wet-deposition fluxes of CHs and MAHs onto the ground.

    Present study focused on the screening of bacterial consortium for biodegradation of monocyclic aromatic hydrocarbon (MAH) and polycyclic aromatic hydrocarbons (PAHs). Target compounds in the present study were naphthalene, acenaphthene, phenanthrene (PAHs), and benzene (MAH). Microbial consortia enriched with the above target compounds were used in screening experiments. Naphthalene-enriched consortium was found to be the most efficient consortium, based on its substrate degradation rate and its ability to degrade other aromatic pollutants with significantly high efficiency. Substrate degradation rate with naphthalene-enriched culture followed the order benzene > naphthalene > acenaphthene > phenanthrene. Chryseobacterium and Rhodobacter were discerned as the predominant species in naphthalene-enriched culture. They are closely associated to the type strain Chryseobacterium arthrosphaerae and Rhodobacter maris, respectively. Single substrate biodegradation studies with naphthalene (PAH) and benzene (MAH) were carried out using naphthalene-enriched microbial consortium (NAPH). Phenol and 2-hydroxybenzaldehyde were identified as the predominant intermediates during benzene and naphthalene degradation, respectively. Biodegradation of toluene, ethyl benzene, xylene, phenol, and indole by NAPH was also investigated. Monod inhibition model was able to simulate biodegradation kinetics for benzene, whereas multiple substrate biodegradation model was able to simulate biodegradation kinetics for naphthalene.

    Full Text Available Burkholderia sp. K24, formerly known as Acinetobacter lwoffii K24, is a soil bacterium capable of utilizing aniline as its sole carbon and nitrogen source. Genomic sequence analysis revealed that this bacterium possesses putative gene clusters for biodegradation of various monocyclic aromatic hydrocarbons (MAHs, including benzene, toluene, and xylene (BTX, as well as aniline. We verified the proposed MAH biodegradation pathways by dioxygenase activity assays, RT-PCR, and LC/MS-based quantitative proteomic analyses. This proteogenomic approach revealed four independent degradation pathways, all converging into the citric acid cycle. Aniline and p-hydroxybenzoate degradation pathways converged into the β-ketoadipate pathway. Benzoate and toluene were degraded through the benzoyl-CoA degradation pathway. The xylene isomers, i.e., o-, m-, and p-xylene, were degraded via the extradiol cleavage pathways. Salicylate was degraded through the gentisate degradation pathway. Our results show that Burkholderia sp. K24 possesses versatile biodegradation pathways, which may be employed for efficient bioremediation of aniline and BTX.

For these concentrations, optical band gap of the films decreased from 1.40 eV to 1.17 eV, whereas the Hall conductivity, mobility and carrier concentration of the films increased slightly from 5.91 × 10-5 to 8.78 × 10-5 (Ω cm)-1, from 148 to 228 cm2 V-1 s-1 and from 1.73 × 1012 to 3.59 × 1012 cm-1, respectively.

  19. Bioequivalence of generic drugs.

    Science.gov (United States)

    Andrade, Chittaranjan

    2015-09-01

    Generic drugs are bioequivalent to the original brand; this is a prerequisite for marketing approval. It is theoretically possible that one generic drug may overestimate the pharmacokinetic (PK) parameters of the original and another generic may underestimate these PK parameters; in consequence, these 2 generics may not be bioequivalent between themselves. The result could be loss of efficacy or development of drug-related adverse effects if these generics are interchanged in stable patients. In a recent study involving 292 indirect comparisons of generic formulations of 9 different drugs, mathematical modeling showed that in most cases (87.0% for maximum concentration, 90.1% for area under the curve, and 80.5% for both) generic drugs are bioequivalent to each other. These reassuring findings notwithstanding, prudence dictates that, in stable patients, generic drugs should be interchanged only if there is a good reason for it. This is because bioequivalent brands of drugs may differ in their excipient content, and this can result in variations in safety profiles.

    2007-04-01

    The effect of trisodium citrate (TSC) on the rheological and physical properties and microstructure of yogurt was investigated. Reconstituted skim milk was heated at 85 degrees C for 30 min, and various concentrations (5 to 40 mM) of TSC were added to the milk, which was then readjusted to pH 6.50. Milk was inoculated with 2% yogurt culture and incubated at 42 degrees C until pH was 4.6. Acid-base titration was used to determine changes in the state of colloidal calcium phosphate (CCP) in milk. Total and soluble Ca contents of the milk were determined. The storage modulus (G') and loss tangent (LT) values of yogurts were measured as a function of pH using dynamic oscillatory rheology. Large deformation rheological properties were also measured. Microstructure of yogurt was observed using confocal scanning laser microscopy, and whey separation was also determined. Addition of TSC reduced casein-bound Ca and increased the solubilization of CCP. The G' value of gels significantly increased with addition of low levels of TSC, and highest G' values were observed in samples with 10 to 20 mM TSC; higher (> 20 mM) TSC concentrations resulted in a large decrease in G' values. The LT of yogurts increased after gelation to attain a maximum at pH approximately 5.1, but no maximum was observed in yogurts made with > or = 25 mM of TSC because CCP was completely dissolved prior to gelation. Partial removal of CCP resulted in an increase in the LT value at pH 5.1. At low TSC levels, the removal of CCP crosslinks may have facilitated greater rearrangement and molecular mobility of the micelle structure, which may have helped to increase G' and LT values of gels by increasing the formation of crosslinks between strands. At high TSC concentrations the micelles were completely disrupted and CCP crosslinks were dissolved, both of which resulted in very weak yogurt gels with large pores obvious in confocal micrographs. Gelation pH and yield stress significantly decreased with the use of

    The crystal structure of anhydrous trisodium citrate, Na3(C6H5O7), has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional theory (DFT). There are two independent five-coordinate Na+and one six-coordinate Na+cations in the asymmetric unit. The [NaO5] and [NaO6] polyhedra share edges and corners to form a three-dimensional framework. There are channels parallel to theaandbaxes in which the remainder of the citrate anions reside. The only hydrogen bonds are an intramolecular one between the hydroxy group and one of the terminal carboxylate O atoms and an intermolecular one between a methylene group and the hydroxyl O atom.

    Doherty, V F; Otitoloju, A A

    2016-10-01

    The widespread distribution of petroleum products arising from the rapid growth of the petroleum industry in Nigeria has resulted in the pollution of the environment through oil spills involving leakages from tankers, pipelines, tank farms, and dumping of waste petroleum products. The impacts and distribution of major toxic components (benzene, toluene, ethylbenzene, and xylene (BTEX)) of petroleum products in water and sediment samples collected from sampling stations in the Lagos lagoon was investigated over a 2-year period (February 2009-July 2010). The distribution of benthic communities in the different sampling stations of the Lagos lagoon was assessed. The determination of hydrocarbon levels in the samples showed that the levels of total hydrocarbon content (THC) in the water samples around the Atlas Cove and Apapa were high with values ranging from 2.03 to 31.38 mg/l and 4.04 to 22.89 mg/l, respectively. The highest value of total BTEX in the lagoon sediment was also recorded in the Apapa station (450.53 μg/kg), where oil depots and tank farm facilities are located. The study of the macrobenthic community structure showed that the species richness ranged from 1.57 to 2.02 in the reference station, Unilag, while in the Atlas Cove, Iddo, and Apapa stations, it ranged from 1.80 to 2.89, 1.95 to 3.03, and 1.86 to 2.95, respectively. The highest number of organisms (183) was recorded in the reference stations, while the least number (46) was recorded in Apapa. The main hydrocarbon pollution indicator species identified in the impacted aquatic stations were Nais eliguis and Heteromastus filiformis. The levels of hydrocarbon observed in the aquatic environment showed that there is widespread contamination as a result of petroleum product importation, storage, and distribution. The assessment of the monocyclic aromatic hydrocarbon and benthic community will therefore provide important tools for early detection, diagnosis, and management of hydrocarbon pollution

    Novel monocyclic cyanoenones examined to date display unique features regarding chemical reactivity as Michael acceptors and biological potency. Remarkably, in some biological assays, the simple structure is more potent than pentacyclic triterpenoids (e.g., CDDO and bardoxolone methyl) and tricycles (e.g., TBE-31). Among monocyclic cyanoenones, 1 is a highly reactive Michael acceptor with thiol nucleophiles. Furthermore, an important feature of 1 is that its Michael addition is reversible. For the inhibition of NO production, 1 shows the highest potency. Notably, its potency is about three times higher than CDDO, whose methyl ester (bardoxolone methyl) is presently in phase III clinical trials. For the induction of NQO1, 1 also demonstrated the highest potency. These results suggest that the reactivity of these Michael acceptors is closely related to their biological potency. Interestingly, in LPS-stimulated macrophages, 1 causes apoptosis and inhibits secretion of TNF-α and IL-1β with potencies that are higher than those of bardoxolone methyl and TBE-31.

    This paper reports on an extension of generic airspace research to explore the amount of memorization and specialized skills required to manage sectors with specific characteristics or factors. Fifty-five retired controllers were given an electronic survey where they rated the amount of memorization or specialized skills needed for sixteen generic airspace factors. The results suggested similarities in the pattern of ratings between different areas of the US (East, Central, and West). The average of the ratings for each area also showed some differences between regions, with ratings being generally higher in the East area. All sixteen factors were rated as moderately to highly important and may be useful for future research on generic airspace, air traffic controller workload, etc.

    Lisano, Michael E., II; Crues, Edwin Z.

    2005-01-01

    The Generic Kalman Filter (GKF) software provides a standard basis for the development of application-specific Kalman-filter programs. Historically, Kalman filters have been implemented by customized programs that must be written, coded, and debugged anew for each unique application, then tested and tuned with simulated or actual measurement data. Total development times for typical Kalman-filter application programs have ranged from months to weeks. The GKF software can simplify the development process and reduce the development time by eliminating the need to re-create the fundamental implementation of the Kalman filter for each new application. The GKF software is written in the ANSI C programming language. It contains a generic Kalman-filter-development directory that, in turn, contains a code for a generic Kalman filter function; more specifically, it contains a generically designed and generically coded implementation of linear, linearized, and extended Kalman filtering algorithms, including algorithms for state- and covariance-update and -propagation functions. The mathematical theory that underlies the algorithms is well known and has been reported extensively in the open technical literature. Also contained in the directory are a header file that defines generic Kalman-filter data structures and prototype functions and template versions of application-specific subfunction and calling navigation/estimation routine code and headers. Once the user has provided a calling routine and the required application-specific subfunctions, the application-specific Kalman-filter software can be compiled and executed immediately. During execution, the generic Kalman-filter function is called from a higher-level navigation or estimation routine that preprocesses measurement data and post-processes output data. The generic Kalman-filter function uses the aforementioned data structures and five implementation- specific subfunctions, which have been developed by the user on

    Thermal inactivation of normal and starved cells of Salmonella Enteritidis on chicken skin previously exposed to different concentrations of acidified sodium chlorite (ASC) or tri-sodium phosphate (TSP) was investigated. Inoculated skin was pretreated with different concentration of ASC or TSP, packaged in bags, and then immersed in a circulating water bath at 60 to 68 °C. The recovery medium was Hektoen enteric agar. D-values, determined by linear regression, for normal cells on chicken skin, were 2.79, 1.17 and 0.53 min whereas D-values for starved cells were 4.15, 1.83 and 0.66 at 60, 64 and 68 °C, respectively. z-values for normal cells were 3.54 and for starved cells were 2.29. Pretreatment of Salmonella Enteritidis cells with 0 to 200 ppm of ASC or 0 to 1.0 % TSP resulted in lower D-values at all temperatures. Sensory results indicated no significance differences for control and treatments. Thus, results of this study indicated that pretreatment of chicken skin with ASC or TSP increased sensitivity of Salmonella Enteritidis to heat without affecting organoleptic quality of chicken meat.

    Full Text Available Natural sepiolite from Andrici (Serbia was functionalized by covalent grafting of N-[3-(trimethoxysilylpropyl]ethylenediamine triacetic acid trisodium salt to the Si-OH sepiolite groups. The functionalized material, MSEAS, was characterized by determination of phase composition by X-ray diffraction (XRD analysis, analysis of morphological characteristics by scanning electron microscopy (SEM, using Fourier transform infrared (FTIR spectroscopy, differential thermal analyses (DTA, determination of specific surface areas and pore size distribution using B.E.T. method and point of zero charge (pHpzc determination.

    Visser, M; Visser, Matt; Hochberg, David

    1997-01-01

    Wormholes and black holes have traditionally been treated a quite separate objects with relatively little overlap. The possibility of a connection arises in that wormholes, if they exist, might have profound influence on black holes, their event horizons, and their internal structure. After discussing some connections, we embark on an overview of what can generally be said about traversable wormhole throats. We discuss the violations of the energy conditions that typically occur at and near the throat of any traversable wormhole and emphasize the generic nature of this result. We discuss the original Morris-Thorne wormhole and its generalization to a spherically symmetric time-dependent wormhole, and also discuss spherically symmetric Brans-Dicke wormholes. We also discuss the relationship with the topological censorship theorem. Finally we turn to a rather general class of wormholes that permit explicit analysis: generic static traversable wormholes (without any symmetry). We define the wormhole throat in te...

    Full Text Available This work presents the Generic Network Location Service based on the Chord implementation utilizing data structures called distributed hash tables (DHT or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee resilience in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes failing and leaving. Generic Network Location Service provides a Location Service system based on DHT technology, which is storing device location records in nodes within a Chord DHT. Location records are consisting of network device identification keys as attributes, which are used to create replicas of additional location records through established Chord hashing mechanisms. Storing device location records, in places address-able (using the DHT lookup by individual location record keys provides a simple way of implementing transla¬tion functions similar to well¬ known network services (e.g. ARP, DNS, ENUM. The generic network location ser¬vice presented in the paper is not supposed to be a substitu¬tion of the existing translation techniques (e.g. ARP, DNS, ENUM, but it is considered as an overlay service that uses data available in existing systems and provides some translations currently unavailable.

    Rationale and objectives: Dedicated contrast agents are now available for contrast-enhanced magnetic resonance angiography (CE-MRA). This study retrospectively compares the safety and diagnostic performance data from Phase III regulatory trials performed to evaluate gadobenate dimeglumine (MultiHance) and gadofosveset trisodium (Vasovist) for renal and peripheral CE-MRA. Materials and methods: Similar examination and blinded assessment methodology was utilized in all studies to determine the safety and diagnostic performance of the agents for detection of significant (>50%) steno-occlusive disease. Digital Subtraction Angiography (DSA) was used as the standard of truth. Diagnostic performance data (sensitivity, specificity, predictive values [PVs], and likelihood ratios [LRs]) were compared (Chi-square test). Results: CE-MRA with gadobenate dimeglumine was more specific (92.4% vs. 80.5%, p < 0.0001) and accurate (83.6% vs. 77.1%, p = 0.022) than CE-MRA with gadofosveset in the detection of significant renal artery stenosis. The average sensitivity was higher for gadofosveset (74.4% vs. 67.3%, p = 0.011) in peripheral vessels although gadobenate dimeglumine was more specific (93.0% vs. 88.2%, p < 0.0001) with no difference in accuracy (86.6% vs. 86.3%, p = 0.66). PPVs were higher (p < 0.0001) for gadobenate dimeglumine in both vascular territories. Pre- to post-test shifts in the probability of detecting significant disease were greater after gadobenate dimeglumine. Adverse events in the renal and peripheral studies were reported by 9.2% and 7.7% of patients after gadobenate dimeglumine compared with 30.3% and 22.1% of patients after gadofosveset. Conclusion: The diagnostic performance of CE-MRA for the detection of significant steno-occlusive disease is similar with gadofosveset and gadobenate dimeglumine although the rate of adverse events appears higher with gadofosveset.

    We designed this study to evaluate the feasibility of using mangafodipir trisodium enhanced functional liver imaging (MT-FLI) for assessing the viable fraction of hepatocytes (VFH) in the liver. We evaluated the change of VFH with using MT-FLI before and after inducing acute hepatic necrosis (AHN) with CCI{sub 4} in the liver of 15 beagle dogs. The MR imaging was performed on a 1.5T MRI unit with using the EFGRE-3D sequence (TR/TE = 4.7/1.1 msec; flip angle: 20.0 .deg. ). We evaluated the linear dependence of the density of viable hepatocytes in AHN on the MR images as compared to that in the corresponding normal livers (D{sub AHN}/D{sub N}) on the VFH in their pathologic specimens, and the change of the VFH from the MT-FLI on that of the laboratory findings (AST, ALT, albumin, bilirubin, PT, ICG-R15) before and after AHN induction. The mean {+-} SD of the VFH from the MT-FLI in AHN was 61.2 {+-} 10.7% of that of the normal ones. The D{sub AHN}/D{sub N} showed strong positive linear dependence on the VFH in their pathologic specimens ({beta} = .769, {rho} < .05). The change of the VFH from MT-FLI showed high linear dependence on that of all the above-mentioned laboratory findings ({beta} < -.933 or > .938, {rho} < .05). The MT-FLI seems to be a feasible method for measuring VFH in the liver.

    A key issue in maintaining Linux device drivers is the need to keep them up to date with respect to evolutions in Linux internal libraries. Currently, there is little tool support for performing and documenting such changes. In this paper we present a tool, spdiff, that identifies common changes...... developers can use it to extract an abstract representation of the set of changes that others have made. Our experiments on recent changes in Linux show that the inferred generic patches are more concise than the corresponding patches found in commits to the Linux source tree while being safe with respect...

    The effects of dipping treatments (15 min) in potable water or in solutions (wt/vol) of 12% trisodium phosphate (TSP), 1,200 ppm acidified sodium chlorite (ASC), 2% citric acid (CA), and 220 ppm peroxyacids (PA) on inoculated pathogenic bacteria (Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus, Salmonella Enteritidis, Escherichia coli, and Yersinia enterocolitica) and skin pH were investigated throughout storage of chicken legs (days 0, 1, 3, and 5) at 3 +/- 1 degrees C. All chemical solutions reduced microbial populations (P 0.05) were observed on water-dipped and control legs. Type of treatment, microbial group, and sampling day influenced microbial counts (P < 0.001). Average reductions with regard to control samples were 0.28 to 2.41 log CFU/g with TSP, 0.33 to 3.15 log CFU/g with ASC, 0.82 to 1.97 log CFU/g with CA, and 0.07 to 0.96 log CFU/g with PA. Average reductions were lower (P < 0.001) for gram-positive (0.96 log CFU/g) than for gram-negative (1.33 log CFU/g) bacteria. CA and ASC were the most effective antimicrobial compounds against gram-positive and gram-negative bacteria, respectively. TSP was the second most effective compound for both bacterial groups. Average microbial reductions per gram of skin were 0.87 log CFU/g with TSP, 0.86 log CFU/g with ASC, 1.39 log CFU/g with CA, and 0.74 log CFU/g with PA for gram-positive bacteria, and 1.28 log CFU/g with TSP, 2.03 log CFU/g with ASC, 1.23 log CFU/g with CA, and 0.78 log CFU/g with PA for gram-negative bacteria. With only a few exceptions, microbial reductions in TSP- and ASC-treated samples decreased and those in samples treated with CA increased throughout storage. Samples treated with TSP and samples dipped in CA and ASC had the highest and lowest pH values, respectively, after treatment. The pH of the treated legs tended to return to normal (6.3 to 6.6) during storage. However, at the end of storage, the pH of legs treated with TSP remained higher and that of legs treated with CA

  12. Generic Quantum Fourier Transforms

    2003-01-01

    The quantum Fourier transform (QFT) is the principal algorithmic tool underlying most efficient quantum algorithms. We present a generic framework for the construction of efficient quantum circuits for the QFT by ``quantizing'' the separation of variables technique that has been so successful in the study of classical Fourier transform computations. Specifically, this framework applies the existence of computable Bratteli diagrams, adapted factorizations, and Gel'fand-Tsetlin bases to offer efficient quantum circuits for the QFT over a wide variety a finite Abelian and non-Abelian groups, including all group families for which efficient QFTs are currently known and many new group families. Moreover, the method gives rise to the first subexponential-size quantum circuits for the QFT over the linear groups GL_k(q), SL_k(q), and the finite groups of Lie type, for any fixed prime power q.

  13. Dimensional regularization is generic

    CERN Document Server

    Fujikawa, Kazuo

    2016-01-01

    The absence of the quadratic divergence in the Higgs sector of the Standard Model in the dimensional regularization is usually regarded to be an exceptional property of a specific regularization. To understand what is going on in the dimensional regularization, we illustrate how to reproduce the results of the dimensional regularization for the $\\lambda\\phi^{4}$ theory in the more conventional regularization such as the higher derivative regularization; the basic postulate involved is that the quadratically divergent induced mass, which is independent of the scale change of the physical mass, is kinematical and unphysical. This is consistent with the derivation of the Callan-Symanzik equation, which is a comparison of two theories with slightly different masses, for the $\\lambda\\phi^{4}$ theory without encountering the quadratic divergence. We thus suggest that the dimensional regularization is generic in a bottom-up approach starting with a successful low-energy theory. We also define a modified version of t...

  14. Generic torus canards

    Science.gov (United States)

    Vo, Theodore

    2017-10-01

    Torus canards are special solutions of fast/slow systems that alternate between attracting and repelling manifolds of limit cycles of the fast subsystem. A relatively new dynamic phenomenon, torus canards have been found in neural applications to mediate the transition from tonic spiking to bursting via amplitude-modulated spiking. In R3, torus canards are degenerate: they require one-parameter families of 2-fast/1-slow systems in order to be observed and even then, they only occur on exponentially thin parameter intervals. The addition of a second slow variable unfolds the torus canard phenomenon, making it generic and robust. That is, torus canards in fast/slow systems with (at least) two slow variables occur on open parameter sets. So far, generic torus canards have only been studied numerically, and their behaviour has been inferred based on averaging and canard theory. This approach, however, has not been rigorously justified since the averaging method breaks down near a fold of periodics, which is exactly where torus canards originate. In this work, we combine techniques from Floquet theory, averaging theory, and geometric singular perturbation theory to show that the average of a torus canard is a folded singularity canard. In so doing, we devise an analytic scheme for the identification and topological classification of torus canards in fast/slow systems with two fast variables and k slow variables, for any positive integer k. We demonstrate the predictive power of our results in a model for intracellular calcium dynamics, where we explain the mechanisms underlying a novel class of elliptic bursting rhythms, called amplitude-modulated bursting, by constructing the torus canard analogues of mixed-mode oscillations. We also make explicit the connection between our results here with prior studies of torus canards and torus canard explosion in R3, and discuss how our methods can be extended to fast/slow systems of arbitrary (finite) dimension.

  20. A Generic Dynamic Emulator

    CERN Document Server

    Albert, Carlo

    2011-01-01

    In applied sciences, we often deal with deterministic simulation models that are too slow for simulation-intensive tasks such as calibration or real-time control. In this paper, an emulator for a generic dynamic model, given by a system of ordinary non-linear differential equations, is developed. The non-linear differential equations are linearized and Gaussian white noise is added to account for the non-linearities. The resulting linear stochastic system is conditioned on a set of solutions of the non-linear equations that have been calculated prior to the emulation. A path-integral approach is used to derive the Gaussian distribution of the emulated solution. The solution reveals that most of the computational burden can be shifted to the conditioning phase of the emulator and the complexity of the actual emulation step only scales like $\\mathcal O(Nnm^2)$, where $N$ is the number of time-points at which the solution is to be emulated, $n$ the number of solutions the emulator is conditioned on and $m$ the n...

    The aim of this work is to obtain further evidence about the salting-out effect produced by the addition of tri-sodium citrate to aqueous solutions of water miscible ionic liquid 1-butyl-3-methylimidazolium bromide ([C{sub 4}mim][Br]) by evaluating the effect of tri-sodium citrate on the thermodynamic properties of aqueous solutions of this ionic liquid. Experimental measurements of density and sound velocity at different temperatures ranging from (288.15 to 308.15) K, the refractive index at 308.15 K and the liquid-liquid phase diagram at different temperatures ranging from (288.15 to 338.15) K for aqueous solutions containing 1-butyl-3-methylimidazolium bromide ([C{sub 4}mim][Br]) and tri-sodium citrate (Na{sub 3}Cit) are taken. The apparent molar volume of transfer of [C{sub 4}mim][Br] from water to aqueous solutions of Na{sub 3}Cit have positive values and it increases by increasing salt molality. Although at high IL molality, the apparent molar isentropic compressibility shows similar behaviour with that of the apparent molar volume. However at low concentrations of IL, the apparent molar isentropic compressibility of transfer of [C{sub 4}mim][Br] from water to aqueous solutions of Na{sub 3}Cit have negative values. The effects of temperature and the addition of Na{sub 3}Cit and [C{sub 4}mim][Br] on the liquid-liquid phase diagram of the investigated system have been studied. It was found that an increase in temperature caused the expansion of the one-phase region. The presence of Na{sub 3}Cit triggers a salting-out effect, leading to significant upward shifts of the liquid-liquid de-mixing temperatures of the system. The effect of temperature on the phase-forming ability in the system investigated has been studied based on a salting-out coefficient obtained from fitting the binodal values to a Setschenow-type equation for each temperature. Based on cloud point values, the energetics of the clouding process have been estimated and it was found that both of

    Little work has been reported on the use of commercial antimicrobials against foodborne pathogens on duck meat. We investigated the effectiveness of trisodium phosphate (TSP) and sodium hypochlorite (SH) as antimicrobial treatments against Campylobacter and Salmonella on duck meat under simulated commercial water chilling conditions. The results were compared to the same treatments on well-studied chicken meat. A six strain Campylobacter or Salmonella cocktail was inoculated (5 ml) at two dilution levels (10(4) and 10(8) cfu/ml) onto 25 g duck or chicken meat with skin and allowed to attach for 10 min. The meat was exposed to three concentrations of pH adjusted TSP (8, 10 and 12% (w/v), pH 11.5) or SH (40, 50 and 60 ppm, pH 5.5) in 30 ml water under simulated spin chiller conditions (4 °C, agitation) for 10 min. In a parallel experiment the meat was placed in the antimicrobial treatments before inoculation and bacterial cocktails were added to the meat after the antimicrobial solution was removed while all other parameters were maintained. Untreated controls and controls using water were included in all experiments. Bacterial numbers were determined on Campylobacter blood-free selective agar and Mueller Hinton agar or xylose deoxycholate agar and tryptone soya agar using the thin agar layer method for Campylobacter and Salmonella, respectively. All TSP concentrations significantly (pCampylobacter (~1.2-6.4 log cfu/cm(2)) and Salmonella (~0.4-6.6 log cfu/cm(2)) on both duck and chicken meat. On duck meat, numbers of Campylobacter were less than the limit of detection at higher concentrations of TSP and numbers of Salmonella were less than the limit of detection at all concentrations of TSP except one. On chicken meat, numbers of Campylobacter and Salmonella were less than the limit of detection only at the lower inoculum level and higher TSP concentrations. By contrast only some of the concentrations of SH significantly (pCampylobacter and Salmonella (~0.2-1.5 log

    2015-09-01

    The definition and reuse of generic software architecture for launchers is not so usual for several reasons: the number of European launcher families is very small (Ariane 5 and Vega for these last decades); the real time constraints (reactivity and determinism needs) are very hard; low levels of versatility are required (implying often an ad hoc development of the launcher mission). In comparison, satellites are often built on a generic platform made up of reusable hardware building blocks (processors, star-trackers, gyroscopes, etc.) and reusable software building blocks (middleware, TM/TC, On Board Control Procedure, etc.). If some of these reasons are still valid (e.g. the limited number of development), the increase of the available CPU power makes today an approach based on a generic time triggered middleware (ensuring the full determinism of the system) and a centralised mission and vehicle management (offering more flexibility in the design and facilitating the long term maintenance) achievable. This paper presents an example of generic software architecture which could be envisaged for future launchers, based on the previously described principles and supported by model driven engineering and automatic code generation.

    2014-12-01

    Full Text Available Linseed oil which has various biomedical applications was encapsulated by chitosan (Chi-based microcapsules in the development of a suitable carrier. Oil droplets formed in oil-in-water emulsion using sodium dodecyl sulfate (SDS as emulsifier was stabilized by Chi, and microcapsules with multilayers were formed by alternate additions of SDS and Chi solutions in an emulsion through electrostatic interaction. No chemical cross-linker was used in the study and the multilayer shell membrane was formed by ionic gelation using Chi and SDS. The rigidification of the shell membrane of microcapsules was achieved by alkali treatment in the presence of a small amount of 1-butanol to reduce aggregation. A trisodium citrate solution was used to stabilize the charge of microcapsules by ionic cross-linking. Effects of butanol during alkali treatment and citrate in post alkali treatment were monitored in terms of morphology and the chemical properties of microcapsules. Various characterization techniques revealed that the aggregation was decreased and surface roughness was increased with layer formation.

    2016-01-01

    Full Text Available sorption of Ni2+ on the sepiolite functionalized by covalent grafting of N-[3-(trimethoxysilylpropyl]ethylenediamine triacetic acid trisodium salt, MSEAS, was studied in batch experiments as a function of the initial metal concentration, the equilibration time, pH value, and temperature. The modification of sepiolite resulted in an enhanced Ni2+ retention with a capacity of 0.261 mmol/g at 298 K. The retention of Ni2+ ions occurred dominantly by specific sorption and exchange of Mg2+ ions from the sepiolite structure. The sorption process followed pseudo-second-order kinetics. The sorption equilibrium results were best described by the non-linear form of the Langmuir Sorption Equation. The values of the thermodynamic parameters (enthalpy, free energy and entropy were calculated from temperature dependent sorption isotherms and these values showed that the sorption of Ni2+ onto modified sepiolite was endothermic.

    2014-03-01

    Full Text Available This article provides insights into proactive safety management and mitigation. An analysis of accident reports reveals categories of supervening causes of accidents which can be directly linked to the concept of generic competencies (information management, communication and coordination, problem solving, and effect control. These findings strongly suggest adding the human element as another safety-constituting pillar to the concept of ship safety next to technology and regulation. We argue that the human element has unique abilities in dealing with critical and highly dynamic situations which can contribute to the system's recovery from non-routine or critical situations. By educating seafarers in generic competencies we claim to enable the people onboard to successfully deal with critical situations.

  1. Efficient Generation of Generic Entanglement

    CERN Document Server

    Oliveira, R; Plenio, M B

    2006-01-01

    We find that generic entanglement is physical, in the sense that it can be generated in polynomial time from two-qubit gates picked at random. We prove as the main result that such a process generates the average entanglement of the uniform (Haar) measure in at most $O(N^3)$ steps for $N$ qubits. This is despite an exponentially growing number of such gates being necessary for generating that measure fully on the state space. Numerics furthermore show a variation cut-off allowing one to associate a specific time with the achievement of the uniform measure entanglement distribution. Various extensions of this work are discussed. The results are relevant to entanglement theory and to protocols that assume generic entanglement can be achieved efficiently.

    In part I, we discussed new drug development, reviewed the history of the generic drug industry, described how generic drugs are approved by the US Food and Drug Administration, and defined the concepts of bioequivalence and therapeutic equivalence. Herein, we explore various factors impacting generic drug use across the different parties involved: the prescriber, the pharmacist, the patient, and the payer. We also include original cost analysis of dermatologic brand name and generic drugs and show the potential cost savings that can be achieved through generic substitution. We conclude with a review of the data addressing potential differences in the effectiveness of brand name versus generic drugs in dermatology. The cost of brand name and generic medications is highly variable by pharmacy, state, and payer. We used one source (www.drugstore.com) as an example and for consistency across all medications discussed herein. Prices included here may not reflect actual retail prices across the United States.

    A generic reference case for disposal of spent nuclear fuel and high-level radioactive waste in crystalline rock is outlined. The generic cases are intended to support development of disposal system modeling capability by establishing relevant baseline conditions and parameters. Establishment of a generic reference case requires that the emplacement concept, waste inventory, waste form, waste package, backfill/buffer properties, EBS failure scenarios, host rock properties, and biosphere be specified. The focus in this report is on those elements that are unique to crystalline disposal, especially the geosphere representation. Three emplacement concepts are suggested for further analyses: a waste packages containing 4 PWR assemblies emplaced in boreholes in the floors of tunnels (KBS-3 concept), a 12-assembly waste package emplaced in tunnels, and a 32-assembly dual purpose canister emplaced in tunnels. In addition, three failure scenarios were suggested for future use: a nominal scenario involving corrosion of the waste package in the tunnel emplacement concepts, a manufacturing defect scenario applicable to the KBS-3 concept, and a disruptive glaciation scenario applicable to both emplacement concepts. The computational approaches required to analyze EBS failure and transport processes in a crystalline rock repository are similar to those of argillite/shale, with the most significant difference being that the EBS in a crystalline rock repository will likely experience highly heterogeneous flow rates, which should be represented in the model. The computational approaches required to analyze radionuclide transport in the natural system are very different because of the highly channelized nature of fracture flow. Computational workflows tailored to crystalline rock based on discrete transport pathways extracted from discrete fracture network models are recommended.

    From atomic nuclei to supernovae, including plates and rocks, every cohesive system can be broken into fragments, provided that the deposited energy is sufficiently large compared to its cohesive energy. We present a simple numerical model for investigating the general properties of fragmentation. By use of molecular dynamics simulations, we study the impact fragmentation of a solid disk of interacting particles with a wall. Regardless of the particular form of the interaction potential, the fragment size distribution exhibits a power law behaviour with an exponent that increases logarithmically with the energy deposited in the system, in agreement with experiments. We expect this behaviour to be generic in fragmentation phenomena. (authors)

  8. Skin rash during treatment with generic itraconazole

    Directory of Open Access Journals (Sweden)

    Antonio De Vuono

    2014-01-01

    Full Text Available Generic drugs have the same active substance, the same pharmaceutical form, the same therapeutic indications and a similar bioequivalence with the reference medicinal product (branded. Although a similar efficacy is postulated, some cases of clinical inefficacy during treatment with generic formulations have been reported. In this case, we describe a woman with onychomycosis that developed a skin rash during treatment with a generic formulation of itraconazole. Drug administration and its re-challenge confirmed the association between itraconazole and skin rash. Both Naranjo probability scale and World Health Organization causality assessment scale documented a probable association between generic-itraconazole and skin rash. The switch from generic formulation to brand one induced an improvement of symptoms. Since we are unable to evaluate the role of each excipient in the development of skin rash, we cannot rule out their involvement. However, more data are necessary to better define the similarities or differences between branded and generic formulations.

    2009-05-01

    Much of the success of small unmanned air vehicles (UAVs) has arguably been due to the widespread availability of low-cost, portable autopilots. While the development of unmanned ground vehicles (UGVs) has led to significant achievements, as typified by recent grand challenge events, to date the UGV equivalent of the UAV autopilot is not available. In this paper we describe our recent research aimed at the development of a generic UGV autopilot. Assuming we are given a drive-by-wire vehicle that accepts as inputs steering, brake, and throttle commands, we present a system that adds sonar ranging sensors, GPS/IMU/odometry, stereo camera, and scanning laser sensors, together with a variety of interfacing and communication hardware. The system also includes a finite state machine-based software architecture as well as a graphical user interface for the operator control unit (OCU). Algorithms are presented that enable an end-to-end scenario whereby an operator can view stereo images as seen by the vehicle and can input GPS waypoints either from a map or in the vehicle's scene-view image, at which point the system uses the environmental sensors as inputs to a Kalman filter for pose estimation and then computes control actions to move through the waypoint list, while avoiding obstacles. The long-term goal of the research is a system that is generically applicable to any drive-by-wire unmanned ground vehicle.

  13. Determinants of generic drug substitution in Switzerland

    Directory of Open Access Journals (Sweden)

    Lufkin Thomas M

    2011-01-01

    Full Text Available Abstract Background Since generic drugs have the same therapeutic effect as the original formulation but at generally lower costs, their use should be more heavily promoted. However, a considerable number of barriers to their wider use have been observed in many countries. The present study examines the influence of patients, physicians and certain characteristics of the generics' market on generic substitution in Switzerland. Methods We used reimbursement claims' data submitted to a large health insurer by insured individuals living in one of Switzerland's three linguistic regions during 2003. All dispensed drugs studied here were substitutable. The outcome (use of a generic or not was modelled by logistic regression, adjusted for patients' characteristics (gender, age, treatment complexity, substitution groups and with several variables describing reimbursement incentives (deductible, co-payments and the generics' market (prices, packaging, co-branded original, number of available generics, etc.. Results The overall generics' substitution rate for 173,212 dispensed prescriptions was 31%, though this varied considerably across cantons. Poor health status (older patients, complex treatments was associated with lower generic use. Higher rates were associated with higher out-of-pocket costs, greater price differences between the original and the generic, and with the number of generics on the market, while reformulation and repackaging were associated with lower rates. The substitution rate was 13% lower among hospital physicians. The adoption of the prescribing practices of the canton with the highest substitution rate would increase substitution in other cantons to as much as 26%. Conclusions Patient health status explained a part of the reluctance to substitute an original formulation by a generic. Economic incentives were efficient, but with a moderate global effect. The huge interregional differences indicated that prescribing behaviours and

    In this paper we study the effect of reference pricing on pharmaceutical prices and ex-penditures when generic entry is endogenously determined. We develop a Salop-type model where a brand-name producer competes with generic producers in terms of prices.

    For economic reasons, the generic substitution of branded medications is common and welcome. These replacements are based on the concept of bioequivalence, which is considered equal to therapeutic equivalence. Regulatory standards for bioequivalence require the 90 % confidence intervals of group averages of pharmacokinetic measures of a generic and the original drug to overlap within ±20 %. However, therapeutic equivalence has been challenged for several psychotropic agents by retrospective studies and case reports. To evaluate the degree of bioequivalence and therapeutic equivalence of branded and generic psychotropic drugs, we performed an electronic search (from database inception until 24 May 2012 and without language restrictions) in PubMed/MEDLINE, Cochrane Library, and Web of Science. Search terms were "(generic) AND (psychotropic OR psychoactive OR antipsychotic OR antiepileptic OR antidepressant OR stimulant OR benzodiazepine)" or the respective individual substances. We included clinical studies, regardless of design, comparing branded with generic psychotropic drug formulations, identifying 35 such studies. We also included case reports/series reporting on outcomes after a switch between brand and generic psychotropics, identifying 145 clinical cases. Bioequivalence studies in healthy controls or animals, in-vitro studies, and health economics studies without medical information were excluded. An overview of the few randomized controlled studies supports that US FDA regulations assure clinically adequate drug delivery in the majority of patients switched from brand to generic. However, with a growing number of competing generic products for one substance, and growing economic pressure to substitute with the currently cheapest generic, frequent generic-generic switches, often unbeknownst to prescribing clinicians, raise concerns, particularly for antiepileptics/mood stabilizers. Generic-generic switches may vary by more than ±20 % from each other in

    固体磷酸三钠(TSP)属于强碱弱酸盐,具有较强的碱性和较高的溶解度,化学性质稳定,能够长期保存.在安全壳喷淋系统(EAS)的喷淋水中添加TSP替代NaOH,能够调节喷淋液的pH值,有效地除去从泄漏的冷却水中释放至安全壳中的碘气体,避免强碱对工作人员的伤害,易于事故后的清理.本文对TSP在EAS系统中的应用进行了分析研究,计算了TSP的用量、pH值调节能力和溶解时间,初步确定了化学物贮存箱的结构、设置方式.在安全壳地坑旁安装TSP贮存箱,使用TSP替代氢氧化钠(NaOH)溶液是可行的.%Trisodium phosphate (TSP) belongs to strong acid-weak base salt, having the strong alkalescence, good solubility and steady chemical property. It can be preserved for a long time. In order to provide the effective trapping of iodine in the water and to prevent the stress corrosion cracking of the metal material, it is necessary to buffer the acid and raise the pH by the addition of trisodium phosphate in the spray water. We have studied TSP application in EAS system through the calculation of TSP quantity, and the ability to adjust pH and dissolution time. The structure and the layout of TSP storage tank could be confirmed. It is concluded that the setting of TSP container beside the containment sump, sodium hydroxide could be replaced by trisodium phosphate.

    2014-12-01

    The market share of generic medicines in France is low compared to other European countries. This perspective paper provides an overview of the generic medicines retail market in France and how the current policy environment may affect the long-term sustainability. Looking at the French generic medicines retail market and the surrounding regulatory framework, all conditions seem to be in place to create a healthy generic medicines market: the country has well-respected regulatory authorities, generic medicines enter the market in a timely manner and prices of generic medicines are competitive compared with other European countries. Despite the success of the demand-side policies targeted at pharmacists and patients, those targeted at physicians were less successful due to a lack of enforcement and a lack of trust in generic medicines by French physicians. Recommendations to increase the use of generic medicines in France round off this perspective paper.

  2. Pharmaceutical policy regarding generic drugs in Belgium.

    Simoens, Steven; De Bruyn, Kristien; Bogaert, Marc; Laekeman, Gert

    2005-01-01

    Pressure to control pharmaceutical expenditure and price competition among pharmaceutical companies are fuelling the development of generic drug markets in EU countries. However, in Belgium, the market for generic drugs is underdeveloped compared with other countries. To promote the use of generic drugs, the government introduced a reference pricing (RP) scheme in 2001. The aim of this paper is to discuss Belgian pharmaceutical policy regarding generic drugs and to analyse how the Belgian drug market has evolved following initiation of the RP scheme. The market share held by generic drugs increased following implementation of the RP scheme. Focusing on volume, average market share (by semester) for generic drugs amounted to 2.05% of the total pharmaceutical market from January 1998 to June 2001, compared with 6.11% from July 2001 to December 2003. As new generic drugs are introduced, their market share tends to increase in the first couple of months, after which it levels off. Faced with increasing generic competition, some manufacturers have launched new variants of their original drug, thereby effectively extending the period of patent protection. Strategies consisting of price reductions in return for the abolition of prescribing conditions and the launch of new dosages or formulations appear to have been successful in maintaining the market share of original drugs. Nevertheless, the introduction of the RP scheme was associated with savings amounting to 1.8% of pharmaceutical expenditure by the third-party payer in 2001 and 2.1% in 2002. The findings of this paper indicate that the RP scheme has stimulated the Belgian generic drug market. However, existing policy has largely failed to take into account the role that physicians and pharmacists can play in stimulating generic drug use. Therefore, further development of the Belgian generic drug market seems to hinge on the creation of appropriate incentives for physicians to prescribe, and for pharmacists to

    2012-03-01

    The cost of health care in the United States is increasing. In order to help control these rising costs, all parties involved in the delivery of health care, including dermatologists, need to be part of the solution of ethically reducing the cost of delivery of care. One potential means of meeting this goal is to increase the use of generic medications in daily practice. Generic medications can offer equally efficacious therapy at significantly lower prices, which can translate into large scale savings for the individual patient, the payer, and the overall health care system. Herein we provide an overview of new drug development, review the history of the generic drug industry, describe how generic drugs are approved by the US Food and Drug Administration, and define the concepts of bioequivalence and therapeutic equivalence. In part II, we explore various factors impacting generic drug use, provide cost analyses of dermatologic brand name and generic drugs, and review data addressing potential differences in the effectiveness of brand name versus generic drugs in dermatology. The cost of brand name and generic medications is highly variable by pharmacy, state, and payer. We used one source (www.drugstore.com) as an example and for consistency across all medications discussed herein. Prices included here may not reflect actual retail prices across the United States.

    2008-01-01

    Since the introduction of generic drugs to the pharmaceutical market a sometimes emotional debate exists whether they are well-investigated and of high quality. There is some uncertainty about whether evidence of bioequivalence is enough to guarantee efficacy and safety of generic drugs. Some physicians ask the question if competent authorities are able to ascertain that the pharmaceutical quality of generics is acceptable. Doctors and patients sometimes are ill at ease about the interchangeability of innovator and generic products. This article describes how the European Union legislation ensures that a generic drug is only approved if its risk-benefit relationship is favourable and that it is essentially similar to the innovator product. In this context pharmacokinetic parameters are accepted as surrogates for clinical results because bioequivalence means therapeutic equivalence as well. For most drugs, current bioequivalence testing generally enables clinicians to routinely substitute generic for innovator products. Published findings, however, suggest that particular drugs may not be ideally suited for generic substitution when a patient is already on that drug. These are the so called critical dose medicinal products (drugs with a narrow therapeutic range). When starting a new therapy with any generic drug, however, its similarity to the innovator drug in terms of efficacy, safety and quality is guaranteed.

    2012-09-01

    Full Text Available The globalization of generic drug manufacturing, supply and testing, and a growing workload that has far outpaced USFDA’s resources has created new challenges. USFDA & Industry propose generic drug user fee to address the need for globalization of the inspection process, and to speed the timely review of generic product applications. The Generic Drug User Fee (GDUF proposal is agreed by generic industry & USFDA and is focused on three key aims: safety, access, and transparency. Under the program, USFDA will receive nearly $1.5 billion over five years in supplemental funding through generic industry user fees in order to help the agency expedite access to generic drugs, enhance drug quality and safety and ensure inspection parity of both foreign and domestic manufacturing sites. GDUF also will help accelerate the market entry of additional manufacturers of drugs currently in short supply and improve quality, consistency, and availability within the supply chain, further helping to mitigate drug shortages. The GDUF new legislation is a milestone for the generic giants and a major win for American health care consumers.

    2008-11-01

    In most therapeutic areas, prescribing generic drugs seems to lower costs without sacrificing efficacy. The use of generic drugs for treating epilepsy may, however, be more controversial. A systematic review of the literature on generic antiepileptic drugs has been carried out based primarily on a bibliographical search in the Medline database. Published studies are usually of a descriptive nature and are sometimes based on generic drugs that were approved in times when regulatory agency requirements were not as strict as they are now. Experts claim that a change in pharmaceutical formulations could cause seizure recurrence in cases that had been successfully controlled in the past, with severe effects on patients. Meanwhile, several health organizations have provided inconsistent recommendations on the use of generic antiepileptic drugs. In order to obtain scientific evidence on the potential risks and benefits of interchanging branded and generic antiepileptic drugs, high methodological comparative studies are necessary. These studies could bring consensus about the role of generic drugs for treating epilepsy.

  11. Generic physical protection logic trees

    Energy Technology Data Exchange (ETDEWEB)

    Paulus, W.K.

    1981-10-01

    Generic physical protection logic trees, designed for application to nuclear facilities and materials, are presented together with a method of qualitative evaluation of the trees for design and analysis of physical protection systems. One or more defense zones are defined where adversaries interact with the physical protection system. Logic trees that are needed to describe the possible scenarios within a defense zone are selected. Elements of a postulated or existing physical protection system are tagged to the primary events of the logic tree. The likelihood of adversary success in overcoming these elements is evaluated on a binary, yes/no basis. The effect of these evaluations is propagated through the logic of each tree to determine whether the adversary is likely to accomplish the end event of the tree. The physical protection system must be highly likely to overcome the adversary before he accomplishes his objective. The evaluation must be conducted for all significant states of the site. Deficiencies uncovered become inputs to redesign and further analysis, closing the loop on the design/analysis cycle.

  12. Generic Magnetic Fusion Reactor Revisited

    Sheffield, John; Milora, Stanley

    2015-11-01

    The original Generic Magnetic Fusion Reactor paper was published in 1986. This update describes what has changed in 30 years. Notably, the construction of ITER is providing important benchmark numbers for technologies and costs. In addition, we use a more conservative neutron wall flux and fluence. But these cost-increasing factors are offset by greater optimism on the thermal-electric conversion efficiency and potential availability. The main examples show the cost of electricity (COE) as a function of aspect ratio and neutron flux to the first wall. The dependence of the COE on availability, thermo-electric efficiency, electrical power output, and the present day's low interest rates is also discussed. Interestingly, at fixed aspect ratio there is a shallow minimum in the COE at neutron flux around 2.5 MW/m2. The possibility of operating with only a small COE penalty at even lower wall loadings (to 1.0 MW/m2 at larger plant size) and the use of niobium-titanium coils are also investigated. J. Sheffield was supported by ORNL subcontract 4000088999 with the University of Tennessee.

    Policy makers around the world seek to encourage generic substitution. In this paper, the importance of prescribing physicians' imperfect agency is tested using the fact that some Swiss jurisdictions allow physicians to dispense drugs on their own account (physician dispensing, PD) while others disallow it. We estimate a model of physician drug choice with the help of drug claim data, finding a significant positive association between PD and the use of generics. While this points to imperfect agency, generics are prescribed more often to patients with high copayments or low incomes.

    Human DNA topoisomerase IIα (htIIα) is a validated target for the development of novel anticancer agents. Starting from our discovered 4-amino-1,3,5-triazine inhibitors of htIIα, we investigated a library of 2,4,6-trisubstituted-1,3,5-triazines for novel inhibitors that bind to the htIIα ATP binding site using a combination of structure-based and ligand-based pharmacophore models and molecular docking. 4,6-substituted-1,3,5-triazin-2(1H)-ones 8, 9 and 14 were identified as novel inhibitors with activity comparable to the established drug etoposide (1). Compound 8 inhibits the htIIα decatenation in a superior fashion to etoposide. Cleavage assays demonstrated that selected compounds 8 and 14 do not act as poisons and antagonize the poison effect of etoposide. Microscale thermophoresis (MST) confirmed binding of compound 8 to the htIIα ATPase domain and compound 14 effectively inhibits the htIIα mediated ATP hydrolysis. The molecular dynamics simulation study provides further insight into the molecular recognition. The 4,6-disubstituted-1,3,5-triazin-2(1H)-ones represent the first validated monocyclic class of catalytic inhibitors that bind to the to the htIIα ATPase domain.

    The availability of a wide range of immunosuppressive therapies has revolutionized the management of patients who have undergone solid organ transplantation (SOT). However, the cost of immunosuppressive drugs remains high. This situation has led to the development of generic equivalents, which are similar in quality, safety, and efficacy to their approved innovator drugs. There are data available for three generic brands, tacrolimus (Intas), tacrolimus (PharOS), and tacrolimus (Sandoz). Bioequivalence has been demonstrated for generic tacrolimus (Sandoz) within a narrow therapeutic range to its innovator tacrolimus drug (Prograf) in both healthy volunteers and kidney transplant patients. Clinical experience with this generic tacrolimus formulation has also been established in both de novo and conversion patients who have undergone kidney and liver transplantation, as well as in conversion of other SOT patients, including lung and heart recipients.

    In this issue Gagne et al. report an elegant case-crossover study of seizures in patients on antiepileptic drugs. They found that a dispensation episode approximately triples the risk of having a seizure within 21 days, but the risk is not statistically different whether the dispensation was of the same brand-name or generic drug as previously used or a switch from brand-name to a generic or from a generic to a brand name. The cause of the seizure might be a delay in taking medication or late redispensation, among others, but apparently the nature of the product dispensed is not relevant in this study; this may alleviate some of the concerns about generic drugs and epilepsy.

    Henderson, J D; Esham, R H

    2001-01-01

    The methodology and criteria for bioequivalence testing have been firmly established by the Food and Drug Administration (FDA). For certain drugs with a narrow therapeutic index (e.g., digoxin, levothyroxine, warfarin), generic substitution may not be advisable or even allowable, depending on the substitution laws of individual states. Digoxin and levothyroxine tablets are examples of drugs for which no New Drug Applications (NDAs) currently exist. However, commercially available generic products for both of these drugs have not been determined by the FDA to be therapeutically equivalent to the innovator products. Generic versions of warfarin have been approved by the FDA as being therapeutically equivalent to the innovator products, as have generic versions of the rescue inhaler albuterol. Yet, misinformation and myths persist regarding the adequacy and proven reliability of the FDA's determination of bioequivalence for these products.

    We consider here the genericity aspects of spacetime singularities that occur in cosmology and in gravitational collapse. The singularity theorems (that predict the occurrence of singularities in general relativity) allow the singularities of gravitational collapse to be either visible to external observers or covered by an event horizon of gravity. It is shown that the visible singularities that develop as final states of spherical collapse are generic. Some consequences of this fact are discussed.

We show that the existence of power-law scaling of the correlation functions (scale invariance) does not determine a unique dynamic scaling form of the correlation functions, which leads to the different anomalous forms of scaling recently observed in growth models. We derive all the existing forms of anomalous dynamic scaling from a new generic scaling ansatz. The different scaling forms are subclasses of this generic scali...

We show that complete information about generic $U(1)^r$ GLSMs can be obtained by studying the GLSM Lagrangian, appropriately modified in the different phases of the theory. This can be used to study the different phases of $L^{a,b,c}$ spaces and their non-supersymmetric counterparts.

  6. The diffusion of generics after patent expiry in Germany.

    Fischer, Katharina Elisabeth; Stargardt, Tom

    2016-11-01

    To identify the influences on the diffusion of generics after patent expiry, we analyzed 65 generic entries using prescription data of a large German sickness fund between 2007 and 2012 in a sales model. According to theory, several elements are responsible for technology diffusion: (1) time reflecting the rate of adaption within the social system, (2) communication channels, and (3) the degree of incremental innovation, e.g., the modifications of existing active ingredient's strength. We investigated diffusion in two ways: (1) generic market share (percentage of generic prescriptions of all prescriptions of a substance) and, (2) generic sales quantity (number of units sold) over time. We specified mixed regression models. Generic diffusion takes considerable time. An average generic market share of about 75 % was achieved not until 48 months. There was a positive effect of time since generic entry on generic market share (p innovation influenced generic market share (mostly p < 0.001), but not generic sales quantity. Market structure, e.g., the number of generic manufacturers (p < 0.001) and prices influenced both generic market share and sales. Imperfections in generic uptake through informational cascades seem to be largely present. Third-party payers could enhance means to promote generic diffusion to amplify savings through generic entry.

  8. Effects of trisodium citrate on morphology of β-NaGd{sub 1-x}Yb{sub x}F{sub 4}:Er{sup 3+} nanocrystals: role of Yb{sup 3+} concentration

    In solvothermal synthesis of Er{sup 3+}-doped NaGd{sub 1-x}Yb{sub x}F{sub 4} nanocrystals, morphology of the nanoparticles is dependent on the molar ratio of the chelating agent (e.g., trisodium citrate) to the lanthanide ions. Usually, addition of chelating agent is reported to be effective only when the molar ratio is below a critical value usually around 1 for the preparation of Er{sup 3+}- and Yb{sup 3+}-doped NaYF{sub 4} nanocrystals. In this work, we found that, by increasing the Yb{sup 3+} concentration, the critical molar ratio can be up to more than 4 in the preparation of Er{sup 3+}-doped NaGd{sub 1-x}Yb{sub x}F{sub 4} nanocrystals, which provides a new route to control the nanoparticles' size. The result is particularly useful for the synthesis of small Er{sup 3+}-doped NaGd{sub 1-x}Yb{sub x}F{sub 4} nanocrystals with high concentration of the Yb{sup 3+} dopant. We also investigated mechanisms on the formation of such particles (β-NaGd{sub 0.3}Yb{sub 0.7}F{sub 4}:Er{sup 3+}) with large size in a sub-micrometer scale, i.e., the aggregation-induced crystal growth. In addition, upconversion luminescence properties of the powdery samples were studied, which is shown to be dependent both on size of the nanoparticles and on dosage of the trisodium citrate.

  10. Effects of generic versus non-generic feedback on motor learning in children.

    Directory of Open Access Journals (Sweden)

    Suzete Chiviacowsky

    Full Text Available Non-generic feedback refers to a specific event and implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. The present study examined the influences of generic versus non-generic feedback on motor performance and learning in 10-year-old children. In the first experiment, using soccer ball kicking at a target as a task, providing participants with generic feedback resulted in worse performance than providing non-generic feedback, after both groups received negative feedback. The second experiment measured more permanent effects. Results of a retention test, performed one day after practicing a throwing task, showed that participants who received non-generic feedback during practice outperformed the generic feedback group, after receiving a negative feedback statement. The findings demonstrate the importance of the wording of feedback. Even though different positive feedback statements may not have an immediate influence on performance, they can affect performance, and presumably individuals' motivation, when performance is (purportedly poor. Feedback implying that performance is malleable, rather than due to an inherent ability, seems to have the potential to inoculate learners against setbacks--a situation frequently encountered in the context of motor performance and learning.

    The list of generic medicines (LGM), published since 1997 by the Agence Française de Sécurité Sanitaire des Produits de Santé (AFFSSaPS), the French Medicine Agency, concerns a special part of the medicines reimbursed by the National Health Insurance (Social Security). The objectives of the present study were: i) to describe the components of this list, based on pharmaceutical, economical and therapeutic characteristics, ii) to study differences between generic and reference products (formulations, excipients, prices, etc.), iii) to analyze information on excipients provided to health care professionals. The 21st version of the LGM (April 2001) was used. Therapeutic value was retrieved from the 2001 AFSSaPS report on the therapeutic value of 4490 reimbursed medicines. Information on excipients in the LGM and the Vidal dictionary (reference prescription book in France) was compared. The products included in the LGM represent 20% of all reimbursed medicines. The mean price differences between generics and their reference products vary between 30 and 50% for more than two thirds of the generic groups. The therapeutic value of the products of the LGM was judged important in 71% of cases (vs 63% for the 4409 assessed medicines) and insufficient in 13% of cases (vs 19%). Information on excipients is often missing and sometimes erroneous. Although the LGM is regularly revised and thus the generic market in perpetual change, the 2001 cross description of this pharmaceutical market provides much informations and raises some concern.

  13. Generic Rigidity Matroids with Dilworth Truncations

    CERN Document Server

    Tanigawa, Shin-ichi

    2010-01-01

    We prove that the linear matroid that defines generic rigidity of $d$-dimensional body-rod-bar frameworks (i.e., structures consisting of disjoint bodies and rods mutually linked by bars) can be obtained from the union of ${d+1 \\choose 2}$ graphic matroids by applying variants of Dilworth truncation $n_r$ times, where $n_r$ denotes the number of rods. This leads to an alternative proof of Tay's combinatorial characterizations of generic rigidity of rod-bar frameworks and that of identified body-hinge frameworks.

    The SENSEI generic in situ interface is an API that promotes code portability and reusability. From the simulation view, a developer can instrument their code with the SENSEI API and then make make use of any number of in situ infrastructures. From the method view, a developer can write an in situ method using the SENSEI API, then expect it to run in any number of in situ infrastructures, or be invoked directly from a simulation code, with little or no modification. This paper presents the design principles underlying the SENSEI generic interface, along with some simplified coding examples.

  15. Associations between generic substitution and patients' attitudes, beliefs and experience

    DEFF Research Database (Denmark)

    Østergaard Rathe, Jette; Larsen, Pia Veldt; Andersen, Morten

    2013-01-01

    Abstract Background Generic substitution has been implemented in many countries, but knowledge about patients’ attitudes, beliefs and experiences is still sparse. Aim To assess associations between generic switching and patients’ attitudes, beliefs and experiences with previous generic switching...... on generic medicine and confidence in the healthcare system. Only prescriptions issued by the general practitioners were included. For each patient we focused on one purchase of a generically substitutable drug (index drug). Patients were identified by means of a dispensing database. Results Earlier generic...... switches within the index ATC code were statistically significantly associated with experience of a generic switch (adjusted OR 5.93 95% CI 4.70; 7.49). Having had more than 5 earlier switches within other ATC codes and having negative views on generic medicines reduced the odds of experiencing a generic...

  16. Should Physicians be Encouraged to use Generic Names and to Prescribe Generic Drugs?

    Science.gov (United States)

    Riaz, Haris; Krasuski, Richard A

    2016-06-01

    While using the brand names seems like a trivial issue at the outset, using these names is inherently problematic. Cardiovascular drugs remain the most commonly prescribed drugs by the physicians. The junior doctors are likely to introject practices of their seniors and consequently to reciprocate from the experiences learnt from their preceptors. Using the generic names may be one way to facilitate prescription of the generic drugs who have a better cost profile and similar efficacy than the more expensive branded drugs. In this editorial, we have outlined several arguments to suggest the importance of using the generic names in academic discussions and clinical documentation.

  17. The importance of being first: evidence from Canadian generic pharmaceuticals.

    Science.gov (United States)

    Hollis, Aidan

    2002-12-01

    This paper uses pooled cross-section data on Canadian ethical drug sales to examine the effect of entry timing on sales of generic drugs. The data is for all drugs for which the first generic competitor entered during the years 1994-1997. It is found that the first generic entrant has a lasting competitive advantage: being first into the market appears to lead to an increase of around 30% in market share (among generics) over a period of at least 4 years. This finding has considerable implications for the current policy of allowing brandname drug companies to issue pseudo-generic equivalents as a preemptive strike against true generic competitors.

  10. Psychiatrists' decision making between branded and generic drugs.

    Science.gov (United States)

    Hamann, Johannes; Mendel, Rosmarie; Kissling, Werner; Leucht, Stefan

    2013-07-01

    To study psychiatrists' decision making between generic and branded antipsychotics or antidepressants a hypothetical decision scenario involving decisions between branded and generic drugs was presented to a sample of German psychiatrists. Factors influencing this decision were identified using a regression analysis. n=410 Psychiatrists participated in the survey. Psychiatrists were more likely to choose branded drugs when imagining choosing the drug for themselves (vs. recommending a drug to a patient). In addition, psychiatrists were more likely to choose generic antidepressants than generic antipsychotics. Additional predictors for choosing a generic drug were a higher share of outpatients, less negative attitudes toward generics and higher uncertainty tolerance. In conclusion, psychiatrists' decision making in choosing between branded or generic antidepressants or antipsychotics is to a large extent influenced by vague attitudes towards properties of generics and branded drugs as well as by "non-evidence based" factors such as uncertainty tolerance.

  8. A developmental analysis of generic nouns in Southern Peruvian Quechua.

    Mannheim, Bruce; Gelman, Susan A; Escalante, Carmen; Huayhua, Margarita; Puma, Rosalía

    2010-01-01

    Generic noun phrases (e.g., "Cats like to drink milk") are a primary means by which adults express generalizations to children, yet they pose a challenging induction puzzle for learners. Although prior research has established that English speakers understand and produce generic noun phrases by preschool age, little is known regarding the cross-cultural generality of generic acquisition. Southern Peruvian Quechua provides a valuable comparison because, unlike English, it is a highly inflected language in which generics are marked by the absence rather than the presence of any linguistic markers. Moreover, Quechua is spoken in a cultural context that differs markedly from the highly educated, middle-class contexts within which earlier research on generics was conducted. We presented participants from 5 age groups (3-6, 7-9, 10-12, 14-35, and 36-90 years of age) with two tasks that examined the ability to distinguish generic from non-generic utterances. In Study 1, even the youngest children understood generics as applying broadly to a category (like "all") and distinct from indefinite reference ("some"). However, there was a developmental lag before children understood that generics, unlike "all", can include exceptions. Study 2 revealed that generic interpretations are more frequent for utterances that (a) lack specifying markers and (b) are animate. Altogether, generic interpretations are found among the youngest participants, and may be a default mode of quantification. These data demonstrate the cross-cultural importance of generic information in linguistic expression.

  13. Towards Generic Interaction Styles for Product Design

    2008-01-01

    A growing uneasiness among users with the experience of current product user interfaces mounts pressure on interaction designers to innovate user interface conventions. In previous research we have shown that a study of the history of product interaction triggers a broader discussion of interaction...... qualities among designers in a team, and that the naming of interaction styles helps establish an aesthetics of interaction design. However, that research focused on one particular product field, namely industrial controllers, and it was yet to be proven, if interaction styles do have generic traits across...... a wider range of interactive products. In this paper we report on five years of continued research into interaction styles for telephones, kitchen equipment, HiFi products and medical devices, and we show how it is indeed possible and beneficial to formulate a set of generic interaction styles....

  14. The Doppler peaks from a generic defect

    CERN Document Server

    Magueijo, J

    1996-01-01

    We investigate which of the exotic Doppler peak features found for textures and cosmic strings are generic novelties pertaining to defects. We find that the ``out of phase'' texture signature is an accident. Generic defects, when they generate a secondary peak structure similar to inflation, apply to it an additive shift. It is not necessary for this shift to be ``out of phase''. We also show which factors are responsible for the absence of secondary oscillations found for cosmic strings. Within this general analysis we finally consider the conditions under which topological defects and inflation can be confused. It is argued that only \\Omega=1 inflation and a defect with a horizon size coherence length have a chance to be confused. Any other inflationary or defect model always differ distinctly.

  16. Generic Data Pipelining Using ORAC-DR

    Science.gov (United States)

    Allan, Alasdair; Jenness, Tim; Economou, Frossie; Currie, Malcolm J.; Bly, Martin J.

    A generic data reduction pipeline is, perhaps, the holy grail for data reduction software. We present work which sets us firmly on the path towards this goal. ORAC-DR is an online data reduction pipeline written by the Joint Astronomy Center (JAC) and the UK Astronomy Technology Center (ATC) and distributed as part of the Starlink Software collection (SSC). It is intended to run with a minimum of observer interaction, and is able to handle data from many different instruments, including SCUBA, CGS4, UFTI, IRCAM and Michelle, with support for IRIS2 and UIST under development. Recent work by Starlink in collaboration with the JAC has resulted in an increase in the pipeline's flexibility, opening up the possibility that it could be used for truly generic data reduction for data from any imaging, and eventually spectroscopic, detector.

A representative list of components and failure modes for SRS risk models was generated by reviewing existing safety analyses and component failure data bases and from suggestions from SRS safety analysts. Then sources of data or failure rate estimates were identified and reviewed for applicability. A major source of information was the Nuclear Computerized Library for Assessing Reactor Reliability, or NUCLARR. This source includes an extensive collection of failure data and failure rate estimates for commercial nuclear power plants. A recent Idaho National Engineering Laboratory report on failure data from the Idaho Chemical Processing Plant was also reviewed. From these and other recent sources, failure data and failure rate estimates were collected for the components and failure modes of interest. This information was aggregated to obtain a recommended generic failure rate distribution (mean and error factor) for each component failure mode.

    2015-01-01

    While developing the aerodynamic database for the Orion spacecraft, the low-speed flight regime (transonic and below) proved to be the most difficult to predict and measure accurately. The flow over the capsule heat shield in descent flight was particularly troublesome for both computational and experimental efforts due to its unsteady nature and uncertainty about the boundary layer state. The data described here were acquired as part of a study to improve the understanding of the overall flow around a generic capsule. The unsteady pressure measurements acquired on a generic capsule shape are presented along with a discussion about the effects of various flight conditions and heat-shield surface roughness on the resulting pressure fluctuations.

    The protection provided by patents on medicines has a limited duration. The expiry of patents expiration allows copies of the drugs to be released, competing with original. At first, they were identical to the original, known as generic drugs, but in recent years, due to the marketing of biological therapies and the expiry of many of their patents, biosimilar drugs have also emerged. These are not exact copies of the original, but, like generic drugs, biosimilar drugs have to demonstrate equivalence to the reference drugs in quality, safety and efficacy. Nevertheless, despite their importance and contribution to sustainability of health system, doctors are sometimes unaware of differences between them, and their impact in terms of clinical and economic effects. An attempt is made to review and clarify certain aspects often unknown by physicians, despite their involvement in their use. Copyright © 2015 SECA. Published by Elsevier Espana.

    Full Text Available Religious texts have been examined by scholars from different theoretical standpoints. However, a close survey of the literature reveals that little attention has been paid to Christian apologetics from a linguistic perspective. Also, an examination of studies along the lines of Generic Structure Potential (henceforth GSP shows that the genre status of Christian apologetics has not been indicated. This gap provides the motivation for this paper, which investigates the GSP of Christian apologetics. Twenty texts written by various key contemporary apologetic writers were purposively selected for the study. The following generic structure potential catalogue was generated:The paper reveals that the elements of the GSP concertedly work to advance, argue for or defend the Christian belief system. The paper also suggests that the model could be applied to other forms of apologetic instances.

For each component failure mode, this information was aggregated to obtain a recommended generic failure rate distribution (mean and error factor based on a lognormal distribution). Results are presented in a table in this report. A major difference between generic database and previous efforts is that this effort estimates failure rates based on actual data (failure events) rather than on existing failure rate estimates. This effort was successful in that over 75% of the results are now based on actual data. Also included is a section on guidelines for more advanced applications of failure rate data. This report describes the results of a project to improve the generic component failure database for the Savannah River site (SRS).

    We study a model theoretic context (finite thorn rank, NIP, with finitely satisfiable generics) which is a common generalization of groups of finite Morley rank and definably compact groups in o-minimal structures. We show that assuming thorn rank 1, the group is abelian-by-finite, and assuming thorn rank 2 the group is solvable by finite. Also a field is algebraically closed.

    Bioequivalence (BE) has always been an important pharmaceutical area, particularly (but not solely) in Mediterranean region, where the use of generic drugs is a relatively recent development. The lack of new therapeutic molecules has concentrated primary research in the hands of a few large pharmaceutical companies.

    We develop a generic spacetime model in General Relativity from which all existing model results are produced under specific assumptions, depending on the case. We classify each type of possible assumption, especially the role of observers and that of symmetries, and discuss their role in the development of a model. We apply the results in a step by step approach to the case of a Bianchi I spacetime and a string fluid.

  8. Generic drug names and social welfare.

    Science.gov (United States)

    Lobo, Félix; Feldman, Roger

    2013-06-01

    This article studies how well International Nonproprietary Names (INNs), the "generic" names for pharmaceuticals, address the problems of imperfect information. Left in private hands, the identification of medicines leads to confusion and errors. Developed in the 1950s by the World Health Organization, INNs are a common, global, scientific nomenclature designed to overcome this failure. Taking stock after sixty years, we argue that the contribution of INNs to social welfare is paramount. They enhance public health by reducing errors and improving patient safety. They also contribute to economic efficiency by creating transparency as the foundation of competitive generic drug markets, reducing transaction costs, and favoring trade. The law in most countries requires manufacturers to designate pharmaceuticals with INNs in labeling and advertising. Generic substitution is also permitted or mandatory in many countries. But not all the benefits of INNs are fully realized because prescribers may not use them. We advocate strong incentives or even legally binding provisions to extend the use of INNs by prescribing physicians and dispensing pharmacists, but we do not recommend replacing brand names entirely with INNs. Instead, we propose dual use of brand names and INNs in prescribing, as in drug labeling.

  9. Generic superweak chaos induced by Hall effect.

    2016-05-01

    We introduce and study the "kicked Hall system" (KHS), i.e., charged particles periodically kicked in the presence of uniform magnetic (B) and electric (E) fields that are perpendicular to each other and to the kicking direction. We show that for resonant values of B and E and in the weak-chaos regime of sufficiently small nonintegrability parameter κ (the kicking strength), there exists a generic family of periodic kicking potentials for which the Hall effect from B and E significantly suppresses the weak chaos, replacing it by "superweak" chaos (SWC). This means that the system behaves as if the kicking strength were κ^{2} rather than κ. For E=0, SWC is known to be a classical fingerprint of quantum antiresonance, but it occurs under much less generic conditions, in particular only for very special kicking potentials. Manifestations of SWC are a decrease in the instability of periodic orbits and a narrowing of the chaotic layers, relative to the ordinary weak-chaos case. Also, for global SWC, taking place on an infinite "stochastic web" in phase space, the chaotic diffusion on the web is much slower than the weak-chaos one. Thus, the Hall effect can be relatively stabilizing for small κ. In some special cases, the effect is shown to cause ballistic motion for almost all parameter values. The generic global SWC on stochastic webs in the KHS appears to be the two-dimensional closest analog to the Arnol'd web in higher dimensional systems.

  10. Generic legislation of new psychoactive drugs.

    2013-03-01

    New psychoactive drugs (NPDs, new psychoactive substances) enter the market all the time. However, it takes several months to ban these NPDs and immediate action is generally not possible. Several European countries and drug enforcement officers insist on a faster procedure to ban NPDs. Introduction of generic legislation, in which clusters of psychotropic drugs are banned in advance, has been mentioned as a possible solution. Here we discuss the pros and cons of such an approach. First, generic legislation could unintentionally increase the expenditures of enforcement, black market practices, administrative burden and health risks for users. Second, it may have a negative impact on research and the development of new treatments. Third, due to the complexity of generic legislation, problems in the enforcement are anticipated due to lack of knowledge about the chemical nomenclature. Finally, various legal options are already available to ban the use, sale and trade of NPDs. We therefore conclude that the currently used scientific benefit-risk evaluation should be continued to limit the adverse health effects of NPDs. Only in emergency cases, where fatal incidents (may) occur, should this approach be overruled.

    2005-01-01

    This study evaluated knowledge and use of generic drugs in a population-based sample of adults from a southern Brazilian city. The outcomes were: the proportion of generics in total medicines used; theoretical and practical knowledge about generics; and strategies used to buy medicines on medical prescriptions. The recall period for drug utilization was 15 days. The proportion of generics in total medicines was 3.9%. While 86.0% knew that generics cost less and 70.0% that the quality is similar to brand name medicines, only 57.0% knew any packaging characteristics that distinguish generics from other medicines. The highest proportion of generic drug utilization was in the antimicrobial pharmacological group. A brand name medicine (with a brand similar to the generic name) was mistakenly classified as a generic through photos by 48.0% of the interviewees. Among subjects who bought medicines in the 15-day period, 18.9% reported buying a generic, but this result should be interpreted with caution, because the population frequently fails to differentiate between generics and other medicines.

    This paper presents a chronoamperometric method to determine tungsten in water using screen-printed carbon electrodes modified with gold nanoparticles and cross linked alkaline phosphatase immobilized in the working electrode. Enzymatic activity over 2-phospho-l-ascorbic acid trisodium salt, used as substrate, was affected by tungsten ions, which resulted in a decrease of chronoamperometric current, when a potential of 200 mV was applied on 10 mM of substrate in a Tris HCl buffer pH 8.00 and 0.36 M of KCl. Calibration curves for the electrochemical method validation, give a reproducibility of 5.2% (n = 3), a repeatability of 9.4% (n = 3) and a detection limit of 0.29 ± 0.01 μM. Enriched tap water, purified laboratory water and bottled drinking water, with a certified tungsten reference solution traceable to NIST, gave a recovery of 97.1%, 99.1% and 99.1% respectively (n = 4 in each case) and a dynamic range from 0.6 to 30 μM. This study was performed by means of a Lineweaver–Burk plot, showing a mixed kinetic inhibition. PMID:25621602

    Generic medicines offer an opportunity for governments to contain pharmaceutical expenditures, since generics are generally 10%-80% lower in price than brand medicines. Belgium has a small generic market that takes up 15% of the total pharmaceutical market in packages sold. To determine the knowledge of consumers about the different available packages of a common over-the-counter medicine (acetaminophen) with regard to price advantage, quality, and effectiveness in a country with a small generic market. We conducted an online survey in the general Flemish population using a questionnaire with 25 statements. The questionnaire also contained 2 informative interventions. First, we showed the price per package and per tablet that the patient would pay in the pharmacy. Second, we provided the respondent with general information about generic medication (equivalence, effectiveness, price, and recognition). Before and after the interventions, we probed for preferences and knowledge about the different packages. Multivariate logistic models were used to examine the independent effects of consumer characteristics on responses to the survey statements. We obtained a sample of 1,636 respondents. The general attitude towards generic medication was positive-only 5% would rather not use a generic. Nevertheless, only 17% of the respondents were able to recognize a generic medicine. Older consumers (aged 60 years and above) were more often confused about the different packages (OR = 2.59, 95% CI = 1.76-3.80, P ≤ 0.001). Consumers without a higher education degree tended to be more doubtful about the difference in effectiveness and quality between the different brands (OR = 0.59, 95% CI = 0.44-0.79, P ≤ 0.001). Consumer recognition of the name of the active substance of acetaminophen was poor. When different brands were displayed, possible price advantage seemed to be an important motive to switch to a cheaper brand. Consumers generally found medicines

    Generic medicine is a pharmaceutical product which is bioequivalent to the innovator product in terms of dosage form, strength, route of administration, quality, safety, performance characteristics, and intended use. Generic medicines are a cornerstone for providing affordable medicines to patients. The major generic markets in the world include United States of America followed by European Union, Canada, Japan, and Australia. The major suppliers of generic medicines China and India are showing tremendous growth in the generic medicine sector. There are many legal and regulatory issues along with quality concerns associated with the use of the generic products. Lately, bilateral international agreements called free trade agreements, delaying tactics by originator companies like strategic patenting and litigations on generic manufacturers, have been a major setback for the generic medicine industry. These issues need to be addressed to optimize the use of generic medicines. The sustainability of generic medicine sector is crucial for improving access to essential medicines for the worldwide. © 2015 Société Française de Pharmacologie et de Thérapeutique.

  17. What Is the Future of Generics in Transplantation?

    2015-11-01

    Generic immunosuppressive drugs are available in Europe, Canada, and the United States. Between countries, there are large differences in the market penetration of generic drugs in general, and for immunosuppressive drugs in particular. The registration criteria for generic immunosuppressive drugs are often criticized. However, it is unlikely that the criteria for registration of narrow therapeutic index drugs are going to change, and bioequivalence studies, performed in healthy volunteers, will remain the backbone of the registration process. It would be good if the registration authorities would demand that all generic variants of an innovator drug have the same pill appearance to reduce errors and promote drug adherence.To allow for safe substitution, a number of criteria need to be fulfilled. Generic substitution should not be taken out of the hands of the treating physicians. Generic substitution can only be done safely if initiated by the prescriber, and in well-informed and prepared patients. Payers should refrain from forcing pharmacists to dispense generic drugs in patients on maintenance treatment with innovator drug. Instead, together with transplant societies, they should design guidelines on how to implement generic immunosuppressive drugs into clinical practice. Substitutions must be followed by control visits to check if the patient is taking the medication correctly and if drug exposure remains stable. Inadvertent, uncontrolled substitutions from 1 generic to another, initiated outside the scope of the prescriber, must be avoided as they are unsafe. Repetitive subsequent generic substitutions result in minimal additional cost savings and have an inherent risk of medication errors.

  18. Generic hierarchical engine for mask data preparation

    2002-07-01

    Electronic layouts are usually flattened on their path from the hierarchical source downstream to the wafer. Mask data preparation has certainly been identified as a severe bottleneck since long. Data volumes are not only doubling every year along the ITRS roadmap. With the advent of optical proximity correction and phase-shifting masks data volumes are escalating up to non-manageable heights. Hierarchical treatment is one of the most powerful means to keep memory and CPU consumption in reasonable ranges. Only recently, however, has this technique acquired more public attention. Mask data preparation is the most critical area calling for a sound infrastructure to reduce the handling problem. Gaining more and more attention though, are other applications such as large area simulation and manufacturing rule checking (MRC). They all would profit from a generic engine capable to efficiently treat hierarchical data. In this paper we will present a generic engine for hierarchical treatment which solves the major problem, steady transitions along cell borders. Several alternatives exist how to walk through the hierarchy tree. They have, to date, not been thoroughly investigated. One is a bottom-up attempt to treat cells starting with the most elementary cells. The other one is a top-down approach which lends itself to creating a new hierarchy tree. In addition, since the variety, degree of hierarchy and quality of layouts extends over a wide range a generic engine has to take intelligent decisions when exploding the hierarchy tree. Several applications will be shown, in particular how far the limits can be pushed with the current hierarchical engine.

A brief description of the functionality of the physical devices making up the system is given. An attempt has been made to integrate the devices for accelerator specific interfacing into a standard microprocessor system, namely, the Universal Device Controller (UDC). The main goals for such a generic device controller are to provide: local computing power; flexibility to configure; and real time event handling. The UDC assemblies and software are described.

    A generic design model for evolutionary algo rithms is proposed in this paper. The model, which was described by UML in details, focuses on the key concepts and mechanisms in evolutionary algorithms. The model not only achieves separation of concerns and encapsulation of implementations by classification and abstraction of those concepts,it also has a flexible architecture due to the application of design patterns. As a result, the model is reusable, extendible,easy to understand, easy to use, and easy to test. A large number of experiments applying the model to solve many different problems adequately illustrate the generality and effectivity of the model.

    Drugs are the third largest source of expenditure under Switzerland's compulsory basic health insurance. Generics, the price of which should be at least 30 per cent less than the cost of the original drugs, can potentially allow substantial savings. Their approval requires bioequivalence studies and their use is safe, although some factors may influence patients' and physicians' acceptance. The increased substitution of biosimilar drugs for more expensive biotech drugs should allow further cost savings. In an attempt to extend the monopoly granted by the original drug patent, some pharmaceutical companies implement "evergreening" strategies including small modifications of the original substance for which the clinical benefit is not always demonstrated.

    A static aeroelastic analysis capability that calculates flexible air loads for generic configuration wings was developed. It was made possible by integrating a finite element structural analysis code (MSC/NASTRAN) and a panel code of aerodynamic analysis based on linear potential flow theory. The framework already built in MSC/NASTRAN was used, and the aerodynamic influence coefficient matrix was computed externally and inserted in the NASTRAN by means of a DMAP program. It was shown that deformation and flexible air loads of an oblique wing configuration including asymmetric wings can be calculated reliably by this code both in subsonic and supersonic speeds.

    We study the holographic entanglement entropy and mutual information for Lorentz boosted subsystems. In holographic CFTs at zero and finite temperature, we find that the mutual information gets divergent in a universal way when the end points of two subsystems are light-like separated. In Lifshitz and hyperscaling violating geometries dual to non-relativistic theories, we show that the holographic entanglement entropy is not well-defined for Lorentz boosted subsystems in general. This strongly suggests that in non-relativistic theories, we cannot make a real space factorization of the Hilbert space on a generic time slice except the constant time slice, as opposed to relativistic field theories.

We prove that the generic compact set $K\\subseteq X$ (in the sense of Baire category) is either finite or there is a continuous gauge function $h$ such that $0<\\mathcal{H}^{h}(K)<\\infty$, where $\\mathcal{H}^h$ denotes the $h$-Hausdorff measure. This answers a question of C. Cabrelli, U. B. Darji, and U. M. Molter. Moreover, for every weak contraction $f\\colon K\\to X$ we have $\\mathcal{H}^{h} (K\\cap f(K))=0$. This is a measure theoretic analogue of a result of M. Elekes.

    The wing-body aerodynamics data base consists of a series of CFD (Computational Fluid Dynamics) simulations about a generic wing body configuration consisting of a ogive-circular-cylinder fuselage and a simple symmetric wing mid-mounted on the fuselage. Solutions have been obtained for Nonlinear Potential (P), Euler (E) and Navier-Stokes (N) solvers over a range of subsonic and transonic Mach numbers and angles of attack. In addition, each solution has been computed on a series of grids, coarse, medium and fine to permit an assessment of grid refinement errors.

    Full Text Available This paper discusses a generic user interface for managing web data that is incorporated in a content management system. The interface is created at run-time from a set of XML documents stored in database. We accentuate the importance of content analysis phase that leads to a well formed data model. Another important aspect is the use of context in the interface and the hierarchical model to represent multiple relationships between hierarchy items. The proposed event model acts like a glue between data management and application logic.

    Full Text Available A Smart Home is an emerging technology, where the electronic devices are controlled automatically based on the occupants activities. The pervasive computing plays a vital role in the smart home environment, which provides the computer-based service to human beings anywhere and anytime. However, when discussing smart home of the future, related studies have focused on providing middleware. The middleware acts as a interface between human beings and the smart devices. In this paper, we have proposed a generic middleware model for smart home that enables interaction between human being and devices and also between various devices based on the context identified in the environment.

    When the patent protection is terminated, the original registered-mark preparation becomes a generic drug, which results in a decrease in its price as compared with the original pharmaceutical. The effects of changes in price relation are discussed from the viewpoint of the generic firms and the manufacturers of original preparations. The differences in the insurance system and legislative regulations of the registration of generic preparations can markedly the size influence of the share of generic drugs in the total consumption of drugs. The future development of generic drugs from a general viewpoint is discussed in relation to the contemporary extensive expiration of patent protection of drugs. The hitherto results are summed up and the topics for the present strategy of the development of generic drugs in the Research Institute for Pharmacy and Biochemistry, or in the Czech Republic, respectively are discussed.

    Generics ("Dogs bark") convey important information about categories and facilitate children's learning. Two studies with parents and their 2- or 4-year-old children (N = 104 dyads) examined whether individual differences in generic language use are as follows: (a) stable over time, contexts, and domains, and (b) linked to conceptual factors. For both children and parents, individual differences in rate of generic production were stable across time, contexts, and domains, and parents' generic usage significantly correlated with that of their own children. Furthermore, parents' essentialist beliefs correlated with their own and their children's rates of generic frequency. These results indicate that generic language use exhibits substantial stability and may reflect individual differences in speakers' conceptual attitudes toward categories. © 2013 The Authors.

  16. The generic danger and the idiosyncratic support

    2016-04-01

    This contribution argues two main points. First, that generic landscapes used in some modelling studies sometimes have properties or cause simulation results that are unrealistic. Such initially flat or straight-sloped landscapes, sometimes with minor random perturbations, e.g. form the backdrop for ecological simulations of vegetation growth and competition that predict catastrophic shifts. Exploratory results for semi-arid systems suggest that the results based on these generic landscapes are end-members from a distribution of results, rather than an unbiased, typical outcome. Apparently, the desire to avoid idiosyncrasy has unintended consequences. Second, we argue and illustrate that in fact new insights often come from close inspection of idiosyncratic case studies. Our examples from landslide systems, connectivity and soil formation show how a central role for the case study - either in empirical work or to provide model targets - has advanced our understanding. Both points contribute to the conclusion that it is dangerous to forget about annoying, small-scale, idiosyncratic and, indeed, perhaps bad-ass case studies in Earth Sciences.

    Full Text Available This study proposes a Generic Hybrid Encryption System (HES under mutual committee of symmetric and asymmetric cryptosystems. Asymmetric (public key Cryptosystems associates several performance issues like computational incompetence, memory wastages, energy consumptions and employment limitations on bulky data sets but they are quite secure and reliable in key exchange over insecure remote communication channels. Symmetric (private key cryptosystems are 100 times out performed, having no such issues but they cannot fulfill non-repudiation, false modifications in secret key, fake modifications in cipher text and origin authentication of both parties while exchanging information. These contradictory issues can be omitted by utilizing hybrid encryption mechanisms (symmetric+asymmetric to get optimal benefits of both schemes. Several hybrid mechanisms are available with different logics but our logic differs in infrastructural design, simplicity, computational efficiency and security as compared to prior hybrid encryption schemes. Some prior schemes are either diversified in performance aspects, customer satisfaction, memory utilization or energy consumptions and some are vulnerable against forgery and password guessing (session key recovery attacks. We have done some functional and design related changes in existing Public Key Infrastructure (PKI to achieve simplicity, optimal privacy and more customer satisfaction by providing Hybrid Encryption System (HES that is able to fulfill all set of standardized security constraints. No such PKI based generic hybrid encryption scheme persists as we have provided in order to manage all these kinds of discussed issues.

    Full Text Available Reusability is the key concept in todays software development environment. The concept of reusability can be achieved by Generic programming approach. C++ templates help us to develop generic code which results in reusable software modules and also identify effectiveness of this reuse strategy. Many researchers have already developed various reusability metrics [9] [7]. In this paper we emphasis on evaluating reusability metrics on weyukers set of properties. Weyukers list of properties has always been a point of reference and suggested as a guiding tool in identification of a good complexity measure by several researchers. We have chosen some recently reported reusability metrics Method Template Inheritance Factor (MTIF and Attribute Template Inheritance factor (ATIF and evaluated them against Weyukers set of principles. We divide our work in a two-step framework. In the first step the metrics are analytically evaluated against a formal list of Weyukers properties and in the second step we calculate LOC metric value by using three different programs designed using template and inheritance features of object-oriented programming and observe that by using template with inheritance property we can reduce number of lines of a project to a great extent.

  20. A Fast Generic Sequence Matching Algorithm

    CERN Document Server

    Musser, David R

    2008-01-01

    A string matching -- and more generally, sequence matching -- algorithm is presented that has a linear worst-case computing time bound, a low worst-case bound on the number of comparisons (2n), and sublinear average-case behavior that is better than that of the fastest versions of the Boyer-Moore algorithm. The algorithm retains its efficiency advantages in a wide variety of sequence matching problems of practical interest, including traditional string matching; large-alphabet problems (as in Unicode strings); and small-alphabet, long-pattern problems (as in DNA searches). Since it is expressed as a generic algorithm for searching in sequences over an arbitrary type T, it is well suited for use in generic software libraries such as the C++ Standard Template Library. The algorithm was obtained by adding to the Knuth-Morris-Pratt algorithm one of the pattern-shifting techniques from the Boyer-Moore algorithm, with provision for use of hashing in this technique. In situations in which a hash function or random a...

  5. Generic medicine pricing in Europe: current issues and future perspective.

    Science.gov (United States)

    Simoens, Steven

    2008-01-01

    This editorial discusses a number of trends affecting the pricing of generic medicines in Europe. With respect to pricing, recent evidence has emerged that European generic medicine manufacturers face competition from Indian manufacturers; that the price level of generic medicines varies substantially between European countries; and that generic medicine manufacturers engage in competition by discount rather than price competition in France, The Netherlands and the UK. These trends suggest that there may be scope for further reducing the prices of generic medicines in several countries. In relation to reference pricing, most European countries have incorporated market incentives within reference pricing systems with a view to promoting price competition. The European experience indicates that the generic medicines industry delivers competitive prices under a reference pricing system if demand-side policies are in place that stimulate physicians, pharmacists and patients to use generic medicines. Finally, caution needs to be exercised when focusing on the drivers of generic medicine pricing as these drivers not only vary between countries, but may also vary within a country. Manufacturers of originator and generic medicines do not take a single pricing approach following patent expiry, but vary their pricing strategy from molecule to molecule.

  6. Brand loyalty, patients and limited generic medicines uptake.

    Science.gov (United States)

    Costa-Font, Joan; Rudisill, Caroline; Tan, Stefanie

    2014-06-01

    The sluggish development of European generic drug markets depends heavily on demand side factors, and more specifically, patients' and doctors' loyalty to branded products. Loyalty to originator drugs, to the point where originator prices rise upon generic entry has been described as the 'generics paradox'. Originator loyalty can emerge for a plethora of reasons; including costs, perceptions about quality and physician advice. We know very little about the behavioural underpinnings of brand loyalty from the consumer or patient standpoint. This paper attempts to test the extent to which patients are brand loyal by drawing upon Spain's 2002 Health Barometer survey as it includes questions about consumer acceptance of generics in a country with exceptionally low generic uptake and substitution at the time of the study. Our findings suggest that at least 13% of the population would not accept generics as substitutes to the originator. These results confirm evidence of brand loyalty for a minority. Alongside high levels of awareness of generics, we find that low cost-sharing levels explain consumer brand loyalty but their impact on acceptance of generic substitution is very small. Higher cost-sharing and exempting fewer patients from cost-sharing have the potential to encourage generic acceptance.

    Science.gov (United States)

    Welty, Timothy E

    2007-06-01

    Generic substitution of antiepileptic drugs is an issue that is gathering a lot of attention in the neurology community but is not receiving much attention within pharmacy. Several proposals have been drafted that restrict a pharmacist's decision-making in generic substitution. These proposals highlight concerns about the pharmacy community related to generic substitution. Careful consideration needs to be given to these issues by pharmacists and pharmacy professional organizations. Unless pharmacy as a profession takes strong positions in support of a pharmacist's ability to make decisions about pharmacotherapy and addresses many of the pharmacy-related problems of generic substitution, policies that negatively impact pharmacy will be established.

For our survey we used a standardized self-questionnaire of ten points. The influence of sex, age, education, medical history, knowledge of generic drugs and experience with generic substitution and medicines was examined through Chi-square tests.RESULTS: The results show that 74% of the participants seemed not to be informed on generic drugs and 26% received valuable and relevant information from their general practitioner or pharmacist. 94% believed that generic medicines are inferior to brand medicines on quality, safety and efficacy.CONCLUSIONS: The main reason for almost all the participants (94% to prefer original medicines, over generics is the insufficient information, they have. The core factors forming patients' opinion and expectations for generic drugs are medical professionals' recommendation and previous experience. The main advantages of the generics according to the participants in the study are the lower price and better accessibility. The results raise the issue of the awareness and level knowledge about generic medicines and the rational drug use in the general population.

    Context This paper reports on the results of treatment of compressive neuralgia using a combination of nucleotides (uridine triphosphate trisodium [UTP] and cytidine monophosphate disodium [CMP]) and vitamin B12. Objectives To assess the safety and efficacy of the combination of nucleotides (UTP and CMP) and vitamin B12 in patients presenting with neuralgia arising from neural compression associated with degenerative orthopedic alterations and trauma, and to compare these effects with isolated administration of vitamin B12. Methods A randomized, double-blind, controlled trial, consisting of a 30-day oral treatment period: Group A (n=200) receiving nucleotides + vitamin B12, and Group B (n=200) receiving vitamin B12 alone. The primary study endpoint was the percentage of subjects presenting pain visual analog scale (VAS) scores ≤20 at end of study treatment period. Secondary study endpoints included the percentage of subjects presenting improvement ≥5 points on the patient functionality questionnaire (PFQ); percentage of subjects presenting pain reduction (reduction in VAS scores at study end in relation to pretreatment); and number of subjects presenting adverse events. Results The results of this study showed a more expressive improvement in efficacy evaluations among subjects treated with the combination of nucleotides + vitamin B12, with a statistically significant superiority of the combination in pain reduction (evidenced by VAS scores). There were adverse events in both treatment groups, but these were transitory and no severe adverse event was recorded during the study period. Safety parameters were maintained throughout the study in both treatment groups. Conclusion The combination of uridine, cytidine, and vitamin B12 was safe and effective in the treatment of neuralgias arising from neural compression associated with degenerative orthopedic alterations and trauma.

  13. Modeling generic aspects of ideal fibril formation

    CERN Document Server

    Michel, Denis

    2016-01-01

    Many different proteins self-aggregate into insoluble fibrils growing apically by reversible addition of elementary building blocks. But beyond this common principle, the modalities of fibril formation are very disparate, with various intermediate forms which can be reshuffled by minor modifications of physico-chemical conditions or amino-acid sequences. To bypass this complexity, the multifaceted phenomenon of fibril formation is reduced here to its most elementary principles defined for a linear prototype of fibril. Selected generic features, including nucleation, elongation and conformational recruitment, are modeled using minimalist hypotheses and tools, by separating equilibrium from kinetic aspects and in vitro from in vivo conditions. These reductionist approaches allow to bring out known and new rudiments, including the kinetic and equilibrium effects of nucleation, the dual influence of elongation on nucleation, the kinetic limitations on nucleation and fibril numbers and the accumulation of complexe...

    1987-01-01

    A static aeroelastic analysis capability that can calculate flexible air loads for generic configuration aircraft was developed. It was made possible by integrating a finite element structural analysis code (MSC/NASTRAN) and a panel code of aerodynamic analysis based on linear potential flow theory. The framework already built in MSC/NASTRAN was used and the aerodynamic influence coefficient matrix is computed externally and inserted in the NASTRAN by means of a DMAP program. It was shown that deformation and flexible airloads of an oblique wing aircraft can be calculated reliably by this code both in subsonic and supersonic speeds. Preliminary results indicating importance of flexibility in calculating air loads for this type of aircraft are presented.

    The using of generic forms (GF) is presented as a potential source of budgetary "saving of money" in the field of pharmaceutical expenses. Not frequently prescribed in Belgium, they win a new interest thanks to the recent making use of the "reference repayment". Sale's authorization of GF is controlled by european rules, but some questions about their identity to original medications remain. Do similarities based only upon qualitative and quantitative composition in active molecules, pharmaceutical forms and biodisponibility give us all requested guaranties? Several cases of discordances can appear; the major elements of non conformity are the nature of excipients, notice's contents and the value of biodisponibility studies. However, in term of economy, in the drug market, development of GF appears to constitute an unavoidable phenomenon.

    This paper presents the result of the modelling and verification of a generic slung load system using a small-scale helicopter. The model is intended for use in simulation, pilot training, estimation, and control. The model is derived using a redundant coordinate formulation based on Gauss......' Principle of Least Constraint using the Udwadia-Kalaba equation and can be used to model all body to body slung load suspension types. The model provides intuitive and easy-to-use means of modelling and simulating different slung load suspension types. It includes detection of, and response to, wire...... slackening and tightening as well as aerodynamic coupling between the helicopter and the load. Furthermore, it is shown how the model can be easily used for multi-lift systems either with multiple helicopters or multiple loads. A numerical stabilisation algorithm is introduced and finally the use...

  20. Generic Adaptively Secure Searchable Phrase Encryption

    Directory of Open Access Journals (Sweden)

    Kissel Zachary A.

    2017-01-01

    Full Text Available In recent years searchable symmetric encryption has seen a rapid increase in query expressiveness including keyword, phrase, Boolean, and fuzzy queries. With this expressiveness came increasingly complex constructions. Having these facts in mind, we present an efficient and generic searchable symmetric encryption construction for phrase queries. Our construction is straightforward to implement, and is proven secure under adaptively chosen query attacks (CQA2 in the random oracle model with an honest-but-curious adversary. To our knowledge, this is the first encrypted phrase search system that achieves CQA2 security. Moreover, we demonstrate that our document collection preprocessing algorithm allows us to extend a dynamic SSE construction so that it supports phrase queries. We also provide a compiler theorem which transforms any CQA2-secure SSE construction for keyword queries into a CQA2-secure SSE construction that supports phrase queries.

  1. Generic small modular reactor plant design.

    Energy Technology Data Exchange (ETDEWEB)

    Lewis, Tom Goslee,; Cipiti, Benjamin B.; Jordan, Sabina Erteza; Baum, Gregory A.

    2012-12-01

    This report gives an overview of expected design characteristics, concepts, and procedures for small modular reactors. The purpose of this report is to provide those who are interested in reducing the cost and improving the safety of advanced nuclear power plants with a generic design that possesses enough detail in a non-sensitive manner to give merit to their conclusions. The report is focused on light water reactor technology, but does add details on what could be different in a more advanced design (see Appendix). Numerous reactor and facility concepts were used for inspiration (documented in the bibliography). The final design described here is conceptual and does not reflect any proposed concept or sub-systems, thus any details given here are only relevant within this report. This report does not include any design or engineering calculations.

    Multi-function fingers that are able to handle multiple workpieces are crucial in improvement of a robot workcell. Design automation of multi-function fingers is highly demanded by robot industries to overcome the current iterative, time consuming and complex manual design process. However, the existing approaches for the multi-function finger design automation are unable to entirely meet the robot industries’ need. This paper proposes a generic approach for design automation of multi-function fingers. The proposed approach completely automates the design process and requires no expert skill. In addition, this approach executes the design process much faster than the current manual process. To validate the approach, multi-function fingers are successfully designed for two case studies. Further, the results are discussed and benchmarked with existing approaches.

  3. Generic Skills from Qur'anic Perspective

    Directory of Open Access Journals (Sweden)

    Siddig Ahmad

    2012-06-01

    Full Text Available Generic skills are defined as a set of skills that are directly related and needed for the working environment. Employers prefer to recruit officials who are competent in interpersonal communication, leadership skill, team work, oral and written skills. They are reluctant to employ graduates lacking certain necessary skills. This reveals the fact that there is a serious gap between the skills that are required by the employers and the skills that the graduates possess. Therefore, this research is focused on five aspects of generic skills namely; communication, team work, problem solving, lifelong learning and self-esteem. From Qur’anic perspective, the same terms have been used except minor differences in using various terms. The thematic approach is used when discussing these aspects from the Qur’an. The findings showed that the ways of effective communication are represented by terms of qawl sadid, qawl ma`ruf, qawl baligh, qawl maysur, qawl karim and qawl layyin. For collective work, ta`aruf and tafahum, as the pre-requisites, should be practiced via ta`awun and takaful. For problem solving, four methods are adapted from the Qur’an such as reflection of the past, observation, demonstration and asking questions. For lifelong learning, the establishment of learning institutions and the self-motivation of learners are two pre-requisites that should be undertaken for its accomplishment. They could be practiced through open learning system, consultation and hands-on learning. Last but not least, for personality development could be built up through physical training, spiritual training and mental training.

  4. Generic Opinion Mining System for Decision Support

    Directory of Open Access Journals (Sweden)

    Dr.P.G.Naik

    2016-04-01

    Full Text Available Social networking sites prove to be indispensible tools for decision making owing to the large repository of user views accumulated over a period of time. Such a real data can be exploited for various purposes such as making buying decisions, analysing the user views about new product launched by a company, product promotion campaign , impact of policy decisions made by a political party on society etc. In the current work the authors have proposed a generic model for feature based polarity determination by sentiment analysis of tweets. This model has been implemented by the seamless integration of R tool, XML, JAVA, Link Parser A practical multistep system, in place, efficiently extracts data from tweet text, pre-process the raw data to remove noise, and tags their polarity. Data used in the current study is derived from online product feature based reviews collected from tweeter tweets. Link parser version 4.1 b is employed for parsing a natural sentence which is broken into multiple tokens corresponding to noun and adjective before being stored in a persistent storage medium. The objectivity score is determined using SentiWordNet 3.0 lexical resource which is parsed using a tool implemented in Java. The linguistic hedges are taken care of using Zadeh’s proposition which modifies the final objectivity score. The objectivity score so computed, provides the necessary guidelines in influencing decisions. The authors have tested the model for product purchase decisions of two different sets of products, smart phone and laptop based on predefined set of features. The model is generic and can be applied to any set of products evaluated on a predefined set of features.

  19. Is bioavailability altered in generic versus brand anticonvulsants?

    Science.gov (United States)

    Jankovic, Slobodan M; Ignjatovic Ristic, Dragana

    2015-03-01

    Therapeutic window of anticonvulsants is not a wide one, with phenytoin being one extreme, which can be classified as a narrow therapeutic index drug, since its ratio between the least toxic and the least effective concentration is less than twofold. In order to obtain marketing authorization, a generic anticonvulsant should demonstrate relative bioequivalence with its brand-name counterpart. However, although bioequivalent, generic anticonvulsants still do not have the same bioavailability as brand-name drugs, which may lead to larger fluctuations of steady-state plasma concentrations, and sometimes to loss of seizure control if a patient is switched from brand-name to generic or from generic to generic anticonvulsant. Generic anticonvulsants are effective, safe and affordable drugs for treatment of epilepsy, and patients could be successfully treated with them from the very beginning. It is switching from brand-name to generic anticonvulsant or from one generic anticonvulsant to another that should be avoided in clinical practice, since subtle differences in bioavailability may disturb optimal degree of seizure control to which the patient was previously successfully titrated.

  20. Generic noun phrases in mother-child conversations.

    Science.gov (United States)

    Pappas, A; Gelman, S A

    1998-02-01

    Generic noun phrases (e.g. Tigers are fierce) are of interest for their semantic properties: they capture 'essential' properties, are timeless, and are context-free. The present study examines use of generic noun phrases by preschool children and their mothers. Mother-child pairs were videotaped while looking through a book of animal pictures. Each page depicted either a single instance of a particular category (e.g. one crab) or multiple instances of a particular category (e.g. many crabs). The results indicated a striking difference in how generics vs. non-generics were distributed, both in the speech of mothers and in the speech of preschool children. Whereas the form of non-generic noun phrases was closely linked to the structure of the page (i.e. singular noun phrases were used more often when a single instance was presented; plural noun phrases were used more often when multiple instances were presented), the form of generic noun phrases was independent of the information depicted (e.g. plural noun phrases were as frequent when only one instance was presented as when multiple instances were presented). We interpret the data as providing evidence that generic noun phrases differ in their semantics and conceptual organization from non-generic noun phrases, both in the input to young children and in children's own speech. Thus, this simple linguistic device may provide input to, and a reflection of, children's early developing notion of 'kinds'.

  9. Generic medicines: solutions for a sustainable drug market?

    Science.gov (United States)

    Dylst, Pieter; Vulto, Arnold; Godman, Brian; Simoens, Steven

    2013-10-01

    Generic medicines offer equally high-quality treatment as originator medicines do at much lower prices. As such, they represent a considerable opportunity for authorities to obtain substantial savings. At the moment, the pharmaceutical landscape is changing and many pharmaceutical companies have altered their development and commercial strategies, combining both originator and generic divisions. In spite of this, the generic medicines industry is currently facing a number of challenges: delayed market access; the limited price differential with originator medicines; the continuous downwards pressure on prices; and the negative perception regarding generic medicines held by some key stakeholder groups. This could jeopardize the long-term sustainability of the generic manufacturing industry. Therefore, governments must focus on demand-side policies, alongside policies to accelerate market access, as the generic medicines industry will only be able to deliver competitive and sustainable prices if they are ensured a high volume. In the future, the generic medicines industry will increasingly look to biosimilars and generic versions of orphan drugs to expand their business.

  10. An audit of generic prescribing in a general surgical department.

    LENUS (Irish Health Repository)

    Gleeson, M

    2013-01-17

    BACKGROUND: The Health Service Executive introduced a generic prescription policy to reduce costs. Despite this, generic prescription rates remain low. AIM: To audit in-patient prescription practice in a single surgical department and identify potential savings which could be realised by adherence to the generic prescribing policy. METHODS: Surgical in-patient charts were obtained at the point of discharge and their drug prescription information was recorded. RESULTS: 51 % of prescriptions involved a trade-name prescription where an appropriate generic equivalent existed. The cost implications for hospital and community patients were found to be greatly affected by substitution policies that exist at hospital pharmacy level. CONCLUSION: There is a need to promote greater adherence to generic prescribing amongst hospital doctors in line with international best practice. It can have a positive impact in terms of safe prescribing and can have cost implications at both hospital and community level.

    The Brazilian generic drugs policy was implemented in 1999 with the aim of stimulating competition in the market, improve the quality of drugs and improve the access of the population to drug treatment. The process of implementing this policy allowed the introduction and discussion of concepts that had never before been used in the context of drug registration in Brazil: bioavailability, bioequivalence, pharmaceutical equivalence, generic drugs, biopharmaceutical classification system, biowaiver. The present article provides definitions for these concepts in the context of Brazilian legislation as well as a historical and chronological description of the implementation of the generic drugs policy in Brazil, including a list of current generic drug legislation. This article contributes to the understanding of the Brazilian generic drugs policy and facilitates the search for information concerning the legal requirements for registration of drugs in Brazil.

  12. Generic switching of warfarin and risk of excessive anticoagulation

    DEFF Research Database (Denmark)

    Hellfritzsch, Maja; Rathe, Jette; Stage, Tore Bjerregaard;

    2015-01-01

    PURPOSE: Generic switching of warfarin was recently repealed in Denmark, as adverse drug reaction (ADR) reports suggested risk of excessive anticoagulation following switches from branded to generic warfarin. We investigated this putative association in a formalized pharmacoepidemiological analysis....... METHODS: We conducted a nationwide cohort study based on Danish healthcare registries, including data from the introduction of generic warfarin until the repeal (January 2011-April 2015). We followed Danish warfarin users over time and compared the rate of incident hospitalizations due to excessive...... anticoagulation (i.e. increased INR or any bleeding requiring hospitalization) in periods following a recent switch to generic warfarin to the rate in periods without a recent switch. RESULTS: We included 105 751 warfarin users, filling a total of 1 539 640 prescriptions for warfarin (2.5% for generic warfarin...

  13. The Impact of Information on Doctors’ Attitudes Toward Generic Drugs

    Aggeliki V. Tsaprantzi MD

    2016-03-01

    Full Text Available The objective of this study is to assess the impact of information on doctors’ attitudes and perceptions toward generics. A cross-sectional survey based on a specially designed 21-item questionnaire was conducted. The survey involved doctors of different specialties working in a public hospital in Greece. The analysis includes descriptive and inferential statistics, reliability and validity tests, as well as structural equation modeling to evaluate the causal model. Statistical analysis was accomplished by using SPSS 20 and Amos 20. A total of 134 questionnaires out of 162 were received, providing a response rate of 82.71%. A number of significant associations were found between information and perceptions about generic medicines with demographic characteristics. It seems that the provision of quality information on generic drugs influences doctors’ attitudes and prescription practices toward generic drugs. This is not a static process but a rather dynamic issue involving information provision policies for strengthening the proper doctors’ attitudes toward generic drugs.

    Dalen, Dag Morten; Furu, Kari; Locatelli, Marilena; Strøm, Steinar

    2011-02-01

    The importance of prices, doctor and patient characteristics, and market institutions for the likelihood of choosing generic drugs instead of the more expensive original brand-name version are examined. Using an extensive dataset extracted from The Norwegian Prescription Database containing all prescriptions dispensed to individuals in February 2004 and 2006 on 23 different drugs (chemical substances) in Norway, we find strong evidence for the importance of both doctor and patient characteristics for the choice probabilities. The price difference between brand and generic versions and insurance coverage both affect generic substitution. Moreover, controlling for the retail chain affiliation of the dispensing pharmacy, we find that pharmacies play an important role in promoting generic substitution. In markets with more recent entry of generic drugs, brand-name loyalty proves to be much stronger, giving less explanatory power to our demand model.

  16. Generic policy in Bulgaria: a policy of failure or success?

    Directory of Open Access Journals (Sweden)

    Assena Stoimenova

    2016-09-01

    Full Text Available Generic medicines play a key role in managing the financial resources for pharmaceuticals in every country. This study analysed the generic policy legislative framework in Bulgaria with the aim to identify whether the policy implementation can be considered successful in the light of an international review of such policies introduced in other countries, or on the contrary, it has failed to deliver the main benefits. Legislative analysis, desktop study and macroeconomic overview of the Bulgarian pharmaceutical market were included. The study showed that only 3 out of 11 important policy elements are implemented in the country. Bulgaria has one of the highest shares of generics, an average of 81.39% (volume, for the studied period (2006–2014. However, further research is needed to evaluate the success of the existing generic policy in Bulgaria, as the market share of generic drugs is not the only measure of the policy efficiency.

  17. Generic Argillite/Shale Disposal Reference Case

    2014-08-08

    properties (parameters) used in these models are different, which not only make inter-model comparisons difficult, but also compromise the applicability of the lessons learned from one model to another model. The establishment of a reference case would therefore be helpful to set up a baseline for model development. A generic salt repository reference case was developed in Freeze et al. (2013) and the generic argillite repository reference case is presented in this report. The definition of a reference case requires the characterization of the waste inventory, waste form, waste package, repository layout, EBS backfill, host rock, and biosphere. This report mainly documents the processes in EBS bentonite and host rock that are potentially important for performance assessment and properties that are needed to describe these processes, with brief description other components such as waste inventory, waste form, waste package, repository layout, aquifer, and biosphere. A thorough description of the generic argillite repository reference case will be given in Jové Colon et al. (2014).

    Some older generic drugs have become very expensive, owing to factors including drug shortages, supply disruptions, and consolidations in the generic-drug industry. But generics manufacturers that legally obtain a market monopoly can also unilaterally raise prices.

    This study evaluated the acid and heat resistance of Salmonella Enteritidis in simulated gastric fluid (pH 2.0) and during thermal treatment (54-60 °C), respectively, after adaptation to lactic acid (LA) or trisodium phosphate (TSP) at various pHs (pH 5.3-9.0). The changes in membrane lipid composition and expression levels of RpoS and RpoH were examined to elucidate their roles in bacterial stress resistance. Transcriptional profile of several virulence-related genes was also analyzed. Results showed that LA-adapted cells at pH 5.3 and 6.3 had higher acid and heat resistance than control cells and cells adapted to TSP at pH 8.3 and 9.0. LA-adapted cells had the lowest ratio of unsaturated to saturated fatty acids, indicating that they might possess a less fluid membrane. It was observed that the expression levels of RpoH and RpoS were upregulated in TSP-adapted cells but not in LA-adapted cells. Thus, these results indicate that the increased acid and heat resistance of LA-adapted S. Enteritidis was possibly due to the decreased membrane fluidity instead of the upregulation of RpoS and RpoH. About 6.0, 2.1, and 2.46-fold upregulation of spvR, avrA, and hilA were observed in cells adapted to TSP at pH 9.0, except sefA that had its highest expression level in the control cells, indicating that the expression of these virulence genes highly depends on environmental conditions. This is the first study to show that the alteration in the cytoplasmic membrane rather than RpoS and RpoH plays a more crucial role in conferring greater acid and heat resistance on LA-adapted S. Enteritidis, thus providing a better understanding on the bacterial stress response to acidic conditions.

  1. Innovation strategies for generic drug companies: moving into supergenerics.

    Ross, Malcolm S F

    2010-04-01

    Pharmaceutical companies that market generic products generally are not regarded as innovators, but rather as companies that produce copies of originator products to be launched at patent expiration. However, many generics companies have developed excellent scientific innovative skills in an effort to circumvent the defense patents of originator companies. More patents per product, in terms of both drug substances (process patents and polymorph patents) and formulations, are issued to generics companies than to companies that are traditionally considered to be 'innovators'. This quantity of issued patents highlights the technical knowledge and skill sets that are available in generics companies. In order to adopt a completely innovative model (ie, the development of NCEs), a generics company would require a completely new set of skills in several fields, including a sufficient knowledge base, project and risk management experience, and capability for clinical data evaluation. However, with relatively little investment, generics companies should be able to progress into the so-called 'supergeneric' drug space - an area of innovation that reflects the existing competencies of both innovative and generics companies.

    2008-07-01

    Experiments in high energy physics use a combination of widely different detector systems to achieve an optimal measurement of particle trajectories. The software package GENFIT has been developed to provide a consistent treatment of track parameter estimation with hits from detectors providing different spatial information, e.g. strip projections, 3-D space points, drift distances to wires, etc. The concept is based on the idea of a full separation of parameterizations (hit-measurements and track models) from the algebra of regression algorithms. This implements the possibility to switch between different track propagation algorithms and detector geometries without changing the core fitting classes. Key components of the system are the Kalman filter and so-called virtual detector planes. An interface to the propagation package GEANE has also been realized. The poster illustrates the object-oriented architecture of the toolkit which uses generic programming techniques to realize the flexible and portable design. Some applications in the framework of the PANDA simulation studies are shown.

  4. A generic program for multistate protein design.

    Directory of Open Access Journals (Sweden)

    Andrew Leaver-Fay

    Full Text Available Some protein design tasks cannot be modeled by the traditional single state design strategy of finding a sequence that is optimal for a single fixed backbone. Such cases require multistate design, where a single sequence is threaded onto multiple backbones (states and evaluated for its strengths and weaknesses on each backbone. For example, to design a protein that can switch between two specific conformations, it is necessary to to find a sequence that is compatible with both backbone conformations. We present in this paper a generic implementation of multistate design that is suited for a wide range of protein design tasks and demonstrate in silico its capabilities at two design tasks: one of redesigning an obligate homodimer into an obligate heterodimer such that the new monomers would not homodimerize, and one of redesigning a promiscuous interface to bind to only a single partner and to no longer bind the rest of its partners. Both tasks contained negative design in that multistate design was asked to find sequences that would produce high energies for several of the states being modeled. Success at negative design was assessed by computationally redocking the undesired protein-pair interactions; we found that multistate design's accuracy improved as the diversity of conformations for the undesired protein-pair interactions increased. The paper concludes with a discussion of the pitfalls of negative design, which has proven considerably more challenging than positive design.

  5. Maximal coherence in a generic basis

    Since quantum coherence is an undoubted characteristic trait of quantum physics, the quantification and application of quantum coherence has been one of the long-standing central topics in quantum information science. Within the framework of a resource theory of quantum coherence proposed recently, a fiducial basis should be preselected for characterizing the quantum coherence in specific circumstances, namely, the quantum coherence is a basis-dependent quantity. Therefore, a natural question is raised: what are the maximum and minimum coherences contained in a certain quantum state with respect to a generic basis? While the minimum case is trivial, it is not so intuitive to verify in which basis the quantum coherence is maximal. Based on the coherence measure of relative entropy, we indicate the particular basis in which the quantum coherence is maximal for a given state, where the Fourier matrix (or more generally, complex Hadamard matrices) plays a critical role in determining the basis. Intriguingly, though we can prove that the basis associated with the Fourier matrix is a stationary point for optimizing the l1 norm of coherence, numerical simulation shows that it is not a global optimal choice.

  6. The harmonic structure of generic Kerr orbits

    Grossman, Rebecca; Perez-Giz, Gabe

    2011-01-01

    Generic Kerr orbits exhibit intricate three-dimensional motion. We offer a classification scheme for these intricate orbits in terms of periodic orbits. The crucial insight is that for a given effective angular momentum $L$ and angle of inclination $\\iota$, there exists a discrete set of orbits that are geometrically $n$-leaf clovers in a precessing {\\it orbital plane}. When viewed in the full three dimensions, these orbits are periodic in $r-\\theta$. Each $n$-leaf clover is associated with a rational number, $1+q_{r\\theta}=\\omega_\\theta/\\omega_r$, that measures the degree of perihelion precession in the precessing orbital plane. The rational number $q_{r\\theta}$ varies monotonically with the orbital energy and with the orbital eccentricity. Since any bound orbit can be approximated as near one of these periodic $n$-leaf clovers, this special set offers a skeleton that illuminates the structure of all bound Kerr orbits, in or out of the equatorial plane.

  7. A Generic Framework for Tsunami Evacuation Planning

    2010-05-01

    Coastal communities are vulnerable with regard to the devastating impacts tsunami waves may generate to life, lifelines, assets and economy. The risk is quantified by rather rare occurrence on one hand, and by high damage to be expected on the other hand. Hence a pure numerical calculation could easily become meaningless. Yet over-dramatizing the threat could become counter-productive taking into account social behaviour and human perception of potential risk of tsunami waves. Local communities would therefore rather act in a "silent" way by gradually improving the level of preparedness. The goal should be to create a concept of an emergency and evacuation plan that could easily be invoked if necessary. Obviously such concepts are based on a huge variety of parameters which can be set in an individual way considering local particularities, scopes and questions of applicability. Nevertheless guidance through all these parameters and their calculations is difficult to find. This abstract proposes a generic framework that summarizes the application of various steps to be taken, the interdependencies of these steps and the three phases of repetition due to generation, mid-term maintenance and long-term revision of such emergency and evacuation plans. The abstract represents the outcome of research work done as part of the EU-funded SCHEMA (scenarios for hazard-induced emergencies management) project.

  8. Modeling generic aspects of ideal fibril formation

    Many different proteins self-aggregate into insoluble fibrils growing apically by reversible addition of elementary building blocks. But beyond this common principle, the modalities of fibril formation are very disparate, with various intermediate forms which can be reshuffled by minor modifications of physico-chemical conditions or amino-acid sequences. To bypass this complexity, the multifaceted phenomenon of fibril formation is reduced here to its most elementary principles defined for a linear prototype of fibril. Selected generic features, including nucleation, elongation, and conformational recruitment, are modeled using minimalist hypotheses and tools, by separating equilibrium from kinetic aspects and in vitro from in vivo conditions. These reductionist approaches allow to bring out known and new rudiments, including the kinetic and equilibrium effects of nucleation, the dual influence of elongation on nucleation, the kinetic limitations on nucleation and fibril numbers, and the accumulation of complexes in vivo by rescue from degradation. Overlooked aspects of these processes are also pointed: the exponential distribution of fibril lengths can be recovered using various models because it is attributable to randomness only. It is also suggested that the same term “critical concentration” is used for different things, involved in either nucleation or elongation.

    Full Text Available The generic software architecture offers a solution for the the information system's development and implementation. A generic software/non-software model could be developed by integrating the enterprise blueprint concept (Zachman and the object oriented paradigm (Coad's archetype concept. The standardization of the generic software architecture for various specific software components could be a direction of crucial importance, offering the guarantee of the quality of the model and increasing the efficiency of the design, development and implementation of the software. This approach is also useful for the implementation of the ERP systems designed to fit the user’s particular requirements.

    A review is given of a number of lasers in a form of photonic integrated circuits realized on InP substrate using a generic integration approach. The potential of these photonic circuits lies in their compactness, low power consumption, and significant reduction of fabrication cost by realization in generic foundry runs. Generic integration platforms offer the possibility of realizing functionally advanced photonic circuits using combinations of just a few standardized and parameterized building blocks. This vibrant field opens new doors to innovative product development for SMEs as well as curiosity-driven research.

    2016-12-01

    Full Text Available The generic name Dorcadion Adans. ex Lindb. is a superfluous and illegitimate name for Orthotrichum Hedw. The new generic name Dorcadionella Plášek, Sawicki & Ochyra is proposed for a segregate of Orthotrichum which comprises species with superficial stomata that are always monoicous and only occasionally produce gemmae on leaves. Dorcadionella affinis (Schrad. ex Brid. Plášek, Sawicki & Ochyra is selected as a type of this new generic name. The genus Dorcadionella consists of 63 species and one variety that have a worldwide distribution. Traditionally, they were all placed in Orthotrichum and the relevant transfers to the new genus are effected in the present account.

    The very word generics stiffens sinews and tightens lips in the pharma industry. It has been proposed that large profits and much pride are now being lost through the creeping forces of intellectual piracy and generic plagiarism [1-3]. In this article, I will argue against this position. Using models from evolution and modern day complexity theory I will attempt to address some of the fears that surround generic pharmaceutical enterprise and to express my own concerns about some of the overly optimistic thinking that occurs with respect to developing world systems and the HIV virus.

    Objectives: To investigate the impact of an educational intervention on doctors’ knowledge and perceptions towards generic medicines and their generic (international non-proprietary name) prescribing practice. Methods: This is a single-cohort pre-/post-intervention pilot study. The study was conducted in a tertiary care hospital in Perak, Malaysia. All doctors from the internal medicine department were invited to participate in the educational intervention. The intervention consisted of an interactive lecture, an educational booklet and a drug list. Doctors’ knowledge and perceptions were assessed by using a validated questionnaire, while the international non-proprietary name prescribing practice was assessed by screening the prescription before and after the intervention. Results: The intervention was effective in improving doctors’ knowledge towards bioequivalence, similarity of generic medicines and safety standards required for generic medicine registration (p = 0.034, p = 0.034 and p = 0.022, respectively). In terms of perceptions towards generic medicines, no significant changes were noted (p > 0.05). Similarly, no impact on international non-proprietary name prescribing practice was observed after the intervention (p > 0.05). Conclusion: Doctors had inadequate knowledge and misconceptions about generic medicines before the intervention. Moreover, international non-proprietary name prescribing was not a common practice. However, the educational intervention was only effective in improving doctors’ knowledge of generic medicines. PMID:26770747

    Generic substitution (GS) is an integral part of drug policy in many countries. Similarly to other countries its introduction in the Czech Republic gave rise to a vibrant discussion. The aim of the study was to map and analyze pharmacists' opinions of, attitudes towards and experiences with generic drugs and GS after the first year from its legislative embodiment in the Czech Republic. All 7,665 members of the Czech Chamber of Pharmacists were addressed to participate in a questionnaire survey between November 2008 and March 2009. The questionnaire consisted of 28 questions concerning the issue of generic drugs and GS and was divided into five sections. All collected data were analyzed using descriptive statistics and correlations were tested by selected parametric and non-parametric tests. A total of 615 completed questionnaire forms were returned (a questionnaire return rate of 8.0%). The demographic characteristics of the respondents were as follows: 470 (76.4%) females, mean age of 37.5 years (SD = 10.4) and 429 (69.6%) pharmacists with a practice specialization. Altogether 345 (56.1%) respondents became aware of the issue of brand name and generic drugs during their undergraduate studies. 378 (61.5%) respondents considered generic drugs as bioequivalent and 455 (74.0%) respondents as therapeutically equivalent to the respective brand name drugs. 99 (16.1%) pharmacists believed that generic products are of lower quality than branded drugs and 69 (11.2%) respondents expected generics to cause more adverse drug reactions. GS was perceived as a positive tool by 476 (77.4%) respondents. Only 71 (11.5%) respondents showed acquaintance with all the legal rules for GS. Legislation awareness and attitude towards GS was correlated with age (p generic drugs and GS. Approaching patients on an individual basis and pharmacists' awareness can minimize adverse drug events caused by generic drugs and at the same time enhance the professional status of pharmacists.

The discovery of penicillin transformed the medicine industry and initiated a search for a better antibiotic every time resulting in several synthetic and semi-synthetic antibiotics. Beginning with the 1937 sulfa drug tragedy, the drug regulations had a parallel growth along with the antibiotics and the antibiotic-based generic Pharma industries. This review article is focused on the scenario depicting current global Pharma industries based on generic antibiotics. Several regulatory aspects involved with these industries have been discussed along with the complexity of the market, issues that could affect their growth, their struggle for quality, and their compliance with the tightened regulations. With the skyrocketing commercialization of antibiotics through generics and the leveraging technologic renaissance, generic industries are involved in providing maximum safer benefits for the welfare of the people, highlighting its need today..

  1. Generic drugs for hypertension: are they really equivalent?

    Cooper-DeHoff, Rhonda M; Elliott, William J

    2013-08-01

    Many antihypertensive drugs are now available in generic formulations at fractions of the cost of their branded counterparts. In the United States, marketing approval for generic medications is usually granted by the Food and Drug Administration on the basis of two simple studies involving dissolution rates and bioavailability in 24 - 36 healthy people, without data regarding antihypertensive efficacy, safety, or long-term outcomes. This process leaves many true disciples of "Evidence-Based Medicine" in a quandary: prescribe only brand-name medications that have been demonstrated in clinical trials to both lower blood pressure and prevent cardiovascular events, or instead recommend lower-priced generic agents that are usually supported by no such data. This review summarizes the current evidence that generic antihypertensive drugs are likely to be safe and effective, may increase the probability of medication availability and adherence for many patients, but, by law, must have a different physical appearance than the original product.

    We propose a new description scheme for MPEG7-: Generic-model-based Description Scheme to describe contents of audio, video, text and other sorts of multimedia.It uses a generic model as the description frame, which provides a simple but useful object-based structure. The main components of the description scheme are generic model, objects and object fcatures. The proposed description scheme is illustrated and exemplified by Extensible Markup Language.It aims at clarity and flexibility to support MPEG-7 applications such as query and edit. We demonstrate its feasibility and efficiency by presenting applications: Digital Broadcasting and Edit System (DEBS) and Non-linear Edit System (NLES) that already used the generic structure or will greatly benefit from it.

    2008-01-01

    When the patent on fluoxetine expired in 2001, prices for it fell sharply and marketing decreased. We investigated how market share for fluoxetine changed with the introduction of the generic. Prescribing information was tracked at a military hospital where providers knew the cost of medication, but were not compelled to use the cheaper form. Market share for fluoxetine among selective serotonin reuptake inhibitors was observed for the 64 months surrounding the introduction, and changes were examined by linear regression analysis. Results showed that in the 32 months before the introduction of the generic, fluoxetine maintained a relatively steady share of prescriptions. After the introduction of the generic, fluoxetine steadily lost market share over time. No significant relationship could be seen between drug company visits and gains for their individual products. Examination of all Department of Defense prescriptions for the 16 months surrounding the introduction of generic fluoxetine showed a similar drop in its market share.

    Generic medicines are clinically interchangeable with original brand medicines and have the same quality, efficacy and safety profiles. They are, nevertheless, much cheaper in price. Thus, while providing the same therapeutic outcomes, generic medicines lead to substantial savings for healthcare systems. Therefore, the quality use of generic medicines is promoted in many countries. In this paper, we reviewed the role of generic medicines in healthcare systems and the experiences of promoting the use of generic medicines in eight selected countries, namely the United States (US), the United Kingdom (UK), Sweden, Finland, Australia, Japan, Malaysia and Thailand. The review showed that there are different main policies adopted to promote generic medicines such as generic substitution in the US, generic prescribing in the UK and mandatory generic substitution in Sweden and Finland. To effectively and successfully implement the main policy, different complementary policies and initiatives were necessarily introduced. Barriers to generic medicine use varied between countries from negative perceptions about generic medicines to lack of a coherent generic medicine policy, while facilitators included availability of information about generic medicines to both healthcare professionals and patients, brand interchangeability guidelines, regulations that support generic substitution by pharmacists, and incentives to both healthcare professionals and patients.

    Proteins operate and interact with partners by dynamically exchanging between functional substates of a conformational ensemble on a rugged free energy landscape. Understanding how these substates are linked by coordinated, collective motions requires exploring a high-dimensional space, which remains a tremendous challenge. While molecular dynamics simulations can provide atomically detailed insight into the dynamics, computational demands to adequately sample conformational ensembles of large biomolecules and their complexes often require tremendous resources. Kinematic models can provide high-level insights into conformational ensembles and molecular rigidity beyond the reach of molecular dynamics by reducing the dimensionality of the search space. Here, we model a protein as a kinematic linkage and present a new geometric method to characterize molecular rigidity from the constraint manifold Q and its tangent space Q at the current configuration q. In contrast to methods based on combinatorial constraint counting, our method is valid for both generic and non-generic, e.g., singular configurations. Importantly, our geometric approach provides an explicit basis for collective motions along floppy modes, resulting in an efficient procedure to probe conformational space. An atomically detailed structural characterization of coordinated, collective motions would allow us to engineer or allosterically modulate biomolecules by selectively stabilizing conformations that enhance or inhibit function with broad implications for human health.

    OpenAIRE

    De Maesschalck, Peter; Dumortier, Freddy

    2006-01-01

    This paper deals with singular perturbation problems for vector fields on 2-dimensional manifolds. "Canard solutions" are solutions that, starting near an attracting normally hyperbolic branch of the singular curve, cross a "turning point" and follow for a while a normally repelling branch of the singular curve. Following the geometric ideas developed by Dumortier and Roussarie in 1996 for the study of canard solutions near a generic turning point, we study canard solutions near non-generic t...

  13. Lorentzian Cobordisms, Compact Horizons and the Generic Condition

    CERN Document Server

    Larsson, Eric

    2014-01-01

    We consider the problem of determining which conditions are necessary for cobordisms to admit Lorentzian metrics with certain properties. In particular, we prove a result originally due to Tipler without a smoothness hypothesis necessary in the original proof. In doing this, we prove that compact horizons in a smooth spacetime satisfying the null energy condition are smooth. We also prove that the "generic condition" is indeed generic in the set of Lorentzian metrics on a given manifold.

    We find conditions that guarantee that a decomposition of a generic third-order tensor in a minimal number of rank-$1$ tensors (canonical polyadic decomposition (CPD)) is unique up to permutation of rank-$1$ tensors. Then we consider the case when the tensor and all its rank-$1$ terms have symmetric frontal slices (INDSCAL). Our results complement the existing bounds for generic uniqueness of the CPD and relax the existing bounds for INDSCAL. The derivation makes use of algebraic geometry. We...

  16. The short-term impact of Ontario's generic pricing reforms.

    Directory of Open Access Journals (Sweden)

    Michael R Law

    Full Text Available BACKGROUND: Canadians pay amongst the highest generic drug prices in the world. In July 2010, the province of Ontario enacted a policy that halved reimbursement for generic drugs from the public drug plan, and substantially lowered prices for private purchases. We quantified the impact of this policy on overall generic drug expenditures in the province, and projected the impact in other provinces had they mimicked this pricing change. METHODS: We used quarterly prescription generic drug dispensing data from the IMS-Brogan CompuScript Audit. We used the price per unit in both the pre- and post-policy period and two economics price indexes to estimate the expenditure reduction in Ontario. Further, we used the post-policy Ontario prices to estimate the potential reduction in other provinces. RESULTS: We estimate that total expenditure on generic drugs in Ontario during the second half of 2010 was between $181 and $194 million below what would be expected if prices had remained at pre-policy level. Over half of the reduction in spending was due to savings on just 10 generic ingredients. If other provinces had matched Ontario's prices, their expenditures over during the latter half of 2010 would have been $445 million lower. DISCUSSION: We found that if Ontario's pricing scheme were adopted nationally, overall spending on generic drugs in Canada would drop at least $1.28 billion annually--a 5% decrease in total prescription drug expenditure. Other provinces should seriously consider both changes to their generic drug prices and the use of more competitive bulk purchasing policies.

    The objective of this study was to compare treatment persistence and rates of seizure-related events in patients who initiate antiepileptic drug (AED) therapy with a generic versus a brand-name product. We used linked electronic medical and pharmacy claims data to identify Medicare beneficiaries who initiated one of five AEDs (clonazepam, gabapentin, oxcarbazepine, phenytoin, zonisamide). We matched initiators of generic versus brand-name versions of these drugs using a propensity score that accounted for demographic, clinical, and health service utilization variables. We used a Cox proportional hazards model to compare rates of seizure-related emergency room (ER) visit or hospitalization (primary outcome) and ER visit for bone fracture or head injury (secondary outcome) between the matched generic and brand-name initiators. We also compared treatment persistence, measured as time to first 14-day treatment gap, between generic and brand-name initiators. We identified 19,760 AED initiators who met study eligibility criteria; 18,306 (93%) initiated a generic AED. In the matched cohort, we observed 47 seizure-related hospitalizations and ER visits among brand-name initiators and 31 events among generic initiators, corresponding to a hazard ratio of 0.53 (95% confidence interval, 0.30 to 0.96). Similar results were observed for the secondary clinical endpoint and across sensitivity analyses. Mean time to first treatment gap was 124.2 days (standard deviation [sd], 125.8) for brand-name initiators and 137.9 (sd, 148.6) for generic initiators. Patients who initiated generic AEDs had fewer adverse seizure-related clinical outcomes and longer continuous treatment periods before experiencing a gap than those who initiated brand-name versions.

    2013-01-01

    Background Controversy exists about the safety of substituting generic anti-epileptic drugs (AEDs). Lamotrigine, the prototypical newer AED, is often used for psychiatric and neurological conditions other than epilepsy. The safety of generic substitution of lamotrigine in diverse populations of AED users is unclear. Objective The objective of this study was to evaluate potential associations between generic substitution of lamotrigine and adverse consequences in a population of diverse users of this drug. Study Design This study was a retrospective cohort-crossover design using state Medicaid claims data from July 2006 through June 2009. Methods Subjects were included in the cohort if they converted from brand to generic lamotrigine and had 2 years of lamotrigine use prior to conversion. The frequency of emergency department (ED) visits, hospitalizations and condition-specific ED visits or hospitalizations were recorded in the 60 days immediately following the conversion to generic lamotrigine, then compared with the incidence of the same events during a randomly selected time period indexed to one of the patient’s past refills of branded lamotrigine. Multivariate conditional logistic regression was used to quantify the association between generic conversion and health services utilization while controlling for changes in lamotrigine dose and concurrent drug use. Results Of the 616 unique subjects included in this analysis, epilepsy was the most common diagnosis (41%), followed by bipolar disorder (32%), pain (30%) and migraine (18%). Conversion to generic lamotrigine was not associated with a statistically significant increase in the odds of an ED visit (adjusted odds ratio [AOR] = 1.35; 95% confidence interval [CI] 0.92, 1.97), hospitalization (AOR = 1.21; 95% CI 0.60, 2.50) or condition-specific encounter (AOR 1.75; 95 CI 0.87, 3.51). Conclusions A statistically significant increase in ED visits, hospitalizations or condition-specific encounters was not

  4. Toward better quality of anticancer generics in India

    2014-01-01

    Full Text Available Treatment of cancer is limited by affordability of patients in the many developing countries including India. Generic drug manufacturers have responded to this scenario by making drugs available at affordable costs, often at less than 10% the cost of the original brand. In our practice, it is found that there is a three-fold higher prescription of generic brands compared to innovator, accompanied by cost savings of up to 80% per prescription. Unfortunately, the regulatory environment prevailing in India is not geared to ensure satisfactory quality of generic products. The standards set by the regulatory agencies for establishing equivalence of generics vis-ΰ-vis the innovator product allow anticancer generics to enter markets without undergoing clinical evaluation. Many drug manufacturing units in India flout good manufacturing practice norms, which was evident during the center for drug evaluation and research classifications inspection in the year 2006. Inferior drugs have therefore, made their way into the Indian markets, compromising the quality of care. The system of drug manufacturing and marketing approval needs a major overhaul, including regular inspection of manufacturing facilities. Bioequivalence should be made mandatory for all oral formulations. Unless these measures are rigidly implemented, the benefits of generic substitution would be seriously undermined.

    Our aim was to systematically identify and compare how generic medications, as defined by the US Food and Drug Administration (FDA), World Health Organization (WHO), and European Medicines Agency (EMA), are classified and defined by regulatory agencies around the world. We focused on emerging markets and selected the most populated countries in each of the WHO regions: Africa, the Americas, Eastern Mediterranean, Europe, Southeast Asia, and Western Pacific. A structured review of published literature was performed through December 2013. Direct information from regulatory agencies and Ministries of Health for each country was extracted. Additionally, key informant interviews were performed for validation. Of the 21 countries selected, approximately half provided an official country-level definition for generic pharmaceuticals. The others did not have any definition or referred to the WHO. Only two-thirds of the countries had specific requirements for generic pharmaceuticals, often associated with clinical interchangeability. Most countries with requirements mention bioequivalence, but few required bioavailability studies explicitly. Over 30% of the countries had other terms associated with generics in their definitions and processes. In countries with generic drug policies, there is reference to patent and/or data protection during the drug registration process. Several countries do not mention good manufacturing practices as part of the evaluation process. Countries in Africa and Eastern Mediterranean regions appear to have a less developed regulatory framework. In summary, there is significant variability in the definition and classification of generic drugs in emerging markets. Standardization of the definitions is necessary to make international comparisons viable.

    2017-04-01

    The aim of this study was to fill the lack of knowledge regarding a more grounded exploration of the consumer's decision-making process in the context of generic drugs. In this perspective, a model, within the theoretical framework of the Theory of Planned Behaviour (TPB), for studying the consumers' purchase intention of generic drugs was developed. An online survey on 2,222 Italian people who bought drugs in the past was conducted. The proposed model was tested through structural equation modelling (SEM). Almost all the constructs considered in the model, except the perceived behavioural control, contribute to explain the consumer's purchase intention of generic drugs, after controlling for demographic variables (age, income, education). Specifically, attitude, subjective norm, past behaviour, self-identity and trust in the pharmacist have a positive influence on the intention to buy generic drugs. On the contrary, perceived risk towards products and brand sensitivity act negatively. The results of the present study could be useful to public policy makers in developing effective policies and educational campaigns aimed at promoting generic drugs. Specifically, marketing efforts should be directed to inform consumers about the generic drugs' characteristics to mitigate the perceived risk towards these products and to raise awareness during their decision-making process.

  7. Generic drugs: Review and experiences from South India.

    The cost of pharmaceuticals, as a percentage of total healthcare spending, has been rising worldwide. This has resulted in strained national budgets and a high proportion of people without access to essential medications. Though India has become a global hub of generic drug manufacturing, the expected benefits of cheaper drugs are not translating into savings for ordinary people. This is in part due to the rise of branded generics, which are marketed at a price point close to the innovator brands. Unbranded generic medicines are not finding their way into prescriptions due to issues of confidence and perception, though they are proven to be much cheaper and comparable in efficacy to branded medicines. The drug inventory of unbranded generic manufacturers fares reasonably when reviewed using the World Health Organization-Health Action International (WHO-HAI) tool for analysing drug availability. Also, unbranded generic medicines are much cheaper when compared to the most selling brands and they can bring down the treatment costs in primary care and family practice. We share our experience in running a community pharmacy for an urban health center in the Pathanamthitta district of Kerala State, which is run solely on generic medicines. The drug availability at the community pharmacy was 73.3% when analyzed using WHO-HAI tool and the savings for the final consumers were up to 93.1%, when compared with most-selling brand of the same formulation.

  8. Medicaid payment for generic drugs: achieving savings and access.

    2010-09-30

    Medicaid payment for generic prescription drugs has been a point of contention for the pharmacy industry over the past few years because of reimbursement formula changes contained in the Deficit Reduction Act (DRA) of 2005. The Patient Protection and Affordable Care Act (PPACA) includes provisions to resolve some of these issues. The DRA reduced the maximum amount the federal government would pay state Medicaid programs for generic drugs, and the Centers for Medicare & Medicaid services (CMS) final regulation, to implement the DRA provisions was met with a lawsuit from the pharmacy industry. An injunction by the federal district court, followed by a congressional moratorium, kept CMS from implementing the regulation and kept the pre-DRA formula for the generic drug payment limit in place. PPACA provisions increase maximum federal reimbursement levels for Medicaid generic drugs, but the impact on the pharmacy industry depends on CMS implementation and state policies. This paper examines Medicaid payment for generic drugs, the DRA and PPACA changes to generic drug reimbursement, the concerns of the pharmacy industry, and the potential impact on access.

    Recent development of high spatial resolution satellites such as IKONOS, Quickbird and Orbview enable observation of the Earth's surface with sub-meter resolution. Compared to the 30 meter resolution of Landsat 5 TM, the amount of information in the output image was dramatically increased. In this era of high spatial resolution, the estimation of spatial quality of images is gaining attention. Historically, the Modulation Transfer Function (MTF) concept has been used to estimate an imaging system's spatial quality. Sometimes classified by target shapes, various methods were developed in laboratory environment utilizing sinusoidal inputs, periodic bar patterns and narrow slits. On-orbit sensor MTF estimation was performed on 30-meter GSD Landsat4 Thematic Mapper (TM) data from the bridge pulse target as a pulse input . Because of a high resolution sensor s small Ground Sampling Distance (GSD), reasonably sized man-made edge, pulse, and impulse targets can be deployed on a uniform grassy area with accurate control of ground targets using tarps and convex mirrors. All the previous work cited calculated MTF without testing the MTF estimator's performance. In previous report, a numerical generic sensor model had been developed to simulate and improve the performance of on-orbit MTF estimating techniques. Results from the previous sensor modeling report that have been incorporated into standard MTF estimation work include Fermi edge detection and the newly developed 4th order modified Savitzky-Golay (MSG) interpolation technique. Noise sensitivity had been studied by performing simulations on known noise sources and a sensor model. Extensive investigation was done to characterize multi-resolution ground noise. Finally, angle simulation was tested by using synthetic pulse targets with angles from 2 to 15 degrees, several brightness levels, and different noise levels from both ground targets and imaging system. As a continuing research activity using the developed sensor

    Authorized generics are identical in formulation to brand drugs, manufactured by the brand company but marketed as a generic. Generics, marketed by generic manufacturers, are required to demonstrate pharmaceutical and bioequivalence to the brand drug, but repetition of clinical trials is not required. This retrospective cohort study compared outcomes for generics and authorized generics, which serves as a generic vs. brand proxy that minimizes bias against generics. For the seven drugs studied between 1999-2014, 5,234 unique patients were on brand drug prior to generic entry and 4,900 (93.6%) switched to a generic. During the 12-months following the brand-to-generic switch, patients using generics vs. authorized generics were similar in terms of outpatient visits, urgent care visits, hospitalizations, and medication discontinuation. The likelihood of emergency department visits was slightly higher for authorized generics compared with generics. These data suggest that generics were clinically no worse than their proxy brand comparator. This article is protected by copyright. All rights reserved.

    2011-07-01

    Historically, brand-name pharmaceuticals have enjoyed long periods of market exclusivity in Japan, given the limited use of generics after patent expiration. To improve the efficiency of the health-care system, however, the government has recently implemented various policies aimed at increasing generic substitution. Although this has created expectations that the Japanese generic drug market may finally take off, to date, generic usage has increased only modestly. After reviewing the incentives of key market participants to choose generics, we argue that previous government policies did not provide proper incentives for pharmacies to boost generic substitution. We offer some recommendations that may help to increase generic usage.

  17. A new generic system for the pantropical Caesalpinia group (Leguminosae)

    2016-01-01

    Abstract The Caesalpinia group is a large pantropical clade of ca. 205 species in subfamily Caesalpinioideae (Leguminosae) in which generic delimitation has been in a state of considerable flux. Here we present new phylogenetic analyses based on five plastid and one nuclear ribosomal marker, with dense taxon sampling including 172 (84%) of the species and representatives of all previously described genera in the Caesalpinia group. These analyses show that the current classification of the Caesalpinia group into 21 genera needs to be revised. Several genera (Poincianella, Erythrostemon, Cenostigma and Caesalpinia sensu Lewis, 2005) are non-monophyletic and several previously unclassified Asian species segregate into clades that merit recognition at generic rank. In addition, the near-completeness of our taxon sampling identifies three species that do not belong in any of the main clades and these are recognised as new monospecific genera. A new generic classification of the Caesalpinia group is presented including a key for the identification of genera, full generic descriptions, illustrations (drawings and photo plates of all genera), and (for most genera) the nomenclatural transfer of species to their correct genus. We recognise 26 genera, with reinstatement of two previously described genera (Biancaea Tod., Denisophytum R. Vig.), re-delimitation and expansion of several others (Moullava, Cenostigma, Libidibia and Erythrostemon), contraction of Caesalpinia s.s. and description of four new ones (Gelrebia, Paubrasilia, Hererolandia and Hultholia), and make 75 new nomenclatural combinations in this new generic system.

  18. Avoidance of generic competition by Abbott Laboratories' fenofibrate franchise.

    2012-05-14

    The ongoing debate concerning the efficacy of fenofibrate has overshadowed an important aspect of the drug's history: Abbott Laboratories, the maker of branded fenofibrate, has produced several bioequivalent reformulations that dominate the market, although generic fenofibrate has been available for almost a decade. This continued use of branded formulations, which cost twice as much as generic versions of fenofibrate, imposes an annual cost of approximately $700 million on the US health care system. Abbott Laboratories maintained its dominance of the fenofibrate market in part through a complex switching strategy involving the sequential launch of branded reformulations that had not been shown to be superior to the first-generation product and patent litigation that delayed the approval of generic formulations. The small differences in dose of the newer branded formulations prevented their substitution with generics of older-generation products. As soon as direct generic competition seemed likely at the new dose level, where substitution would be allowed, Abbott would launch another reformulation, and the cycle would repeat. Based on the fenofibrate example, our objective is to describe how current policy can allow pharmaceutical companies to maintain market share using reformulations of branded medications, without demonstrating the superiority of next-generation products.

  19. Affordance-based 3D feature for generic object recognition

    Iizuka, M.; Akizuki, S.; Hashimoto, M.

    2017-03-01

    Techniques for generic object recognition, which targets everyday objects such as cups and spoons, and techniques for approach vector estimation (e.g. estimating grasp position), which are needed for carrying out tasks involving everyday objects, are considered necessary for the perceptual system of service robots. In this research, we design feature for generic object recognition so they can also be applied to approach vector estimation. To carry out tasks involving everyday objects, estimating the function of the target object is critical. Also, as the function of holding liquid is found in all cups, so a function is shared in each type (class) of everyday objects. We thus propose a generic object recognition method that can estimate the approach vector by expressing an object's function as feature. In a test of the generic object recognition of everyday objects, we confirmed that our proposed method had a 92% recognition rate. This rate was 11% higher than the mainstream generic object recognition technique of using convolutional neural network (CNN).

  20. ASSESSMENT OF QUALITY OF GENERICS IN CARDIOLOGY: REALITY AND POSSIBILITIES

    Directory of Open Access Journals (Sweden)

    V. V. Yakusevich

    2005-01-01

    Full Text Available Wide presence of original drugs’ copies, the so-called “generics”, on the pharmaceutical market is analyzed. The positive side of this expansion is connected with the lower price of generics, which makes it possible to decrease the costs of treatment. From the other side with the advent of big number of copies of the original drugs it becomes more difficult to assess the quality of each particular generic. Russian legislation in the field of registration allows selling in the country almost all drugs, which have at least minimal similarity to the original. The problem of pre-registration studies of bioequivalency of original and analogue drugs, therapeutical equivalency is widely observed. Concrete proposals of how to prevent the overflow of the Russian market with the generics with the unproved efficacy and safety are considered.

  4. Price regulation and generic competition in the pharmaceutical market.

    Dalen, Dag Morten; Strøm, Steinar; Haabeth, Tonje

    2006-09-01

    In March 2003 the Norwegian government implemented yardstick-based price regulation schemes on a selection of drugs subjected to generic competition. The retail price cap, termed the "index price," on a drug (chemical substance) was set equal to the average of the three lowest producer prices on that drug, plus a fixed wholesale and retail margin. This is supposed to lower barriers of entry for generic drugs and to trigger price competition. Using monthly data over the period 1998-2004 for the six drugs (chemical entities) included in the index price system, we estimate a structural model enabling us to examine the impact of the reform on both demand and market power. Our results suggest that the index price helped to increase the market shares of generic drugs and succeeded in triggering price competition.

  5. A proof of Connelly's conjecture on 3-connected generic cycles

    Berg, Alex Rune; Jordán, Tibor

    2001-01-01

    A graph G = (V , E) is called a generic circuit if |E| = 2|V| - 2 and every X ⊂ V with 2 ≥ |X| ≥ |V| - 1 satisfies i(X) ≤ 2|X| - 3. Here i(X) denotes the number of edges induced by X. The operation extension subdivides an edge uw of a graph by a new vertex v and adds a new edge vz for some vertex z...... ≠ u, w. Connelly conjectured that every 3-connected generic circuit can be obtained from K4 by a sequence of extensions. We prove this conjecture. As a corollary, we also obtain a special case of a conjecture of Hendrickson on generically globally rigid graphs....

  6. [Users sceptical about generic drugs: an anthropological approach].

    Science.gov (United States)

    Sarradon-Eck, A; Blanc, M-A; Faure, M

    2007-06-01

    Since the enactment of the 2002 legislative measures favoring the prescription of generic drugs, various quantitative studies have shown that approval by prescribers and users has risen in France. Nevertheless, scepticism remains as well as distrust towards these drugs focusing on their effectiveness compared with brand-name drugs, on potential dangers, and on the interruption they cause in prescription and consumption habits. Using a comprehensive approach, this article analyzes the social and cultural logic behind the negative image of generic drugs. The materials issued from an ethnographic study on the prescription of drugs for high blood pressure. Sixty-eight interviews were undertaken between April 2002 and October 2004 with people (39 women and 29 men, between the age of 40 and 95, 52 over the age of 60) treated for over a year for high blood pressure in rural areas in the Southeast of France. Thirteen people provided unsolicited opinions about generic drugs. Analysis of the information collected shows that users have various representations of generic drugs, including the idea of counterfeited and foreign drugs. These representations interfere with the adjustment process and the development of consumer loyalty. They are part of a set of social representations about drugs which form and express the user's reality. In these representations, the drug is an ambivalent object, carrier of both biological effectiveness and toxicity; it is also the metonymical extension of the prescriber, bestowing upon the prescription a symbolic value. By placing the generic drug in its network of symbolic and social meaning, this study highlights the coherence of the scepticism towards generic drugs by consumers (and prescribers) with a system of common opinion in which drugs are everyday things, personalized and compatible with users, symbolic exchange carriers in the physician-patient relationship, and in which confidence in the drug is also that given to the health care

    Martínez-Huerta, H.; Pérez-Lorenzana, A.

    2017-06-01

    One of the most studied approaches in phenomenology to introduce the breaking of Lorentz symmetry is the generic approach. This consist on the modification of the free particle dispersion relation by the addition of an extra power law term of order n on energy or momentum. Using this approach in the photon sector, we have calculated the generic rates for vacuum Cherenkov radiation and photon decay, for any order n, at leading order. Explicit results for the decay and emission rates for the lowest values of n are also presented.

    2009-12-15

    A general method to derive the diagonal representation for a generic matrix valued quantum Hamiltonian is proposed. In this approach new mathematical objects like non-commuting operators evolving with the Planck constant promoted as a running variable are introduced. This method leads to a formal compact expression for the diagonal Hamiltonian which can be expanded in a power series of the Planck constant. In particular, we provide an explicit expression for the diagonal representation of a generic Hamiltonian to the second order in the Planck constant. This result is applied, as a physical illustration, to Dirac electrons and neutrinos in external fields. (orig.)

    Previous research has shown that a manufacturer's promotional strategy for a brand name drug is typically affected by generic entry. However, little is known about how newer strategies to extend patent life, including product reformulation introduction or obtaining approval to market for additional clinical indications, influence promotion. To examine the relationships among promotional expenditures, generic entry, reformulation entry and new indication approval. We used quarterly data on national product-level promotional spending (including expenditures for physician detailing and direct-to-consumer advertising [DTCA], and the retail value of free samples distributed in physician offices) for selective serotonin reuptake inhibitors (SSRIs) over the period 1997-2004. We estimated econometric models of detailing, DTCA and total quarterly promotional expenditures as a function of the timing of generic entry, entry of new product formulations and US FDA approval for new clinical indications for existing medications in the SSRI class. Expenditures by pharmaceutical manufacturers for promotion of antidepressant medications was the main outcome measure. Over the period 1997-2004, there was considerable variation in the composition of promotional expenditures across the SSRIs. Promotional expenditures for the original brand molecule decreased dramatically when a reformulation of the molecule was introduced. Promotional spending (both total and detailing alone) for a specific molecule was generally lower after generic entry than before, although the effect of generic entry on promotional spending appears to be closely linked with the choice of product reformulation strategy pursued by the manufacturer. Detailing expenditures for Paxil were increased after the manufacturer received FDA approval to market the drug for generalized anxiety disorder (GAD), while the likelihood of DTCA outlays for the drug was not changed. In contrast, FDA approval to market Paxil and Zoloft

    To evaluate factors associated with "Generic drug prescription" (GDP) behaviour in Spain using the ASE (Attitude, Social Influence, Self-Efficacy) Model. General Practitioners were sent a validated and anonymous questionnaire measuring the ASE and Motivation variables for GDP and their generic drug prescription percentage. Most (n=486; 61.98%) responded to this cross-sectional survey. The mean scores and the 95% confidence intervals (95% CI) were calculated. A binary logistic regression was used to identify the variables that best predict GDP behaviour. The main advantages and motivations for GDP were "saving money" and "protecting professional ethics". The greatest social influences were "doctors' personal preferences" and "authorities' pressure". GDP accounted for a scarce 15% of the total prescription. ASE and Motivation items were the best predictors: they explain 25% of being a 'high prescriber'. The highest prescribers were paediatricians (OR=5.07), workers in rural settings (OR=3.68) and professionals with high Motivation (OR=1.17) and Attitude (OR=1.11) scores. GDP percentage is very low compared with other countries. Interventions to modify the Attitudes of Primary Care doctors towards generic drugs should be implemented. Better informed patients, longer doctor appointment times and more varied dosage forms of generic drugs would also facilitate improvements in GDP. Copyright © 2010 Elsevier Ireland Ltd.

    Directory of Open Access Journals (Sweden)

    María José Bezanilla

    2014-01-01

    Full Text Available This paper focuses on the design of a serious game for the teaching and assessment of generic competences, placing particular emphasis on the competences assessment aspect. Taking into account important aspects of competence assessment such as context, feedback and transparency, among other aspects, and using the University of Deusto's Generic Competences Assessment Model based on the defining of levels, indicators and descriptors as a reference point, a serious game has been designed for the development and evaluation of two Generic Competences: Problem Solving and Entrepreneurship, aimed at final-year undergraduate and first-year postgraduate students. The design process shows that having a Competence Assessment Model based on levels, indicators and descriptors is of great help in defining the game's scenarios and learning and assessment activities. Serious games can also be excellent resources to help in the development and assessment of generic competences, but not as a unique tool, since the concept of competence in itself is highly complex (integrating knowledge, skills, attitudes and values and some elements might require other methods and techniques for its development. It also reveals the difficulties of evaluating competences in general and through serious games in particular.

Two years after high generic drug prices became a public controversy, Reuters is reporting that 20 states filed a lawsuit Thursday against Mylan, Teva Pharmaceuticals and four other generic drug makers (1. The suit alleges the companies conspired to fix prices or allocated markets to prop up prices. The civil lawsuit, led by antitrust investigators in Connecticut, comes one day after the U.S. Department of Justice filed criminal charges against two former executives of the generic drug maker, Heritage. The states attorneys general asked the court to order the companies to disgorge ill-gotten gains, which were not defined, pay attorneys' fees and stop collusion. Of the states in the Southwest only Nevada is participating in the lawsuit. The cases are part of a broader generic drug pricing probe that remains under way at the state and federal level, as well as in the U.S. Congress. In 2014, media reports of …

    Determine, according to the Beer-Fick criteria, the prevalence of drugs potentially inappropriate for the elderly available as generic medication in Brazil. Analysis of the list of generic medications issued by " Diário Oficial da União" on July/12/2004 and of the page of the National Agency for Sanitary Surveillance (ANVISA) - www.anvisa.gov.br, using the Beers-Fick criteria. From the list of 299 products 20 (6.7% of the total) included in the Beers-Fick criteria were analyzed, mainly in the categories of anxiolytics, platelet antiaggregants, antiallergics, anti-angina and vasodilators, antiarrythmics, antidepressants, antispasmodics, anti-hypertensive's, non steroid antinflammatories, antiulceratives and cardiac glycosides. These criteria do not include drugs such as cough suppressants, cinnarizine, diltiazem, piracetam, quinolones, xanthines, creams, ointments and ophthalmic solutions which are also present in the list of generic medication. The Beers-Fick criteria may prevent use of drugs potentially inappropriate for the elderly, however, it should be stressed that these criteria are not complete for Brazilian generic medications.

    2014-01-01

    Objective To assess the level of knowledge, perceptions and usage profile for generic drugs among laypersons. Methods A cross-sectional study was conducted with 278 volunteers (180 women and 98 men, aged 37.1±15.8 years). A questionnaire was drawn up with questions on their use, perceptions and knowledge of generic drugs. Results Most respondents (99.6%) knew that generic drugs exist, but only 48.6% were able to define them correctly, while 78.8% of the respondents had some information about generics. This information was obtained mainly through television (49.3%). In terms of generic drug characteristics, 79.1% stated that they were confident about their efficacy, 74.8% believed that generic drugs have the same effect as branded medications, 88.8% said that generics were priced lower than branded medications, and 80.2% stated that they bought generic drugs because of price. With regard to drugs prescribed by medical practitioners, 17.6% of the participants said that their doctors never prescribed generics and only 7.5% confirmed that their doctors always prescribed generics. Conclusion For the lay public, the sample in this study has sufficient knowledge of generic drugs in terms of definition, efficacy and cost. Consequently, the volunteers interviewed are very likely to use generics. Furthermore, the results of this study indicate that programs should be implemented in order to boost generic drug prescriptions by medical practitioners. PMID:25295444

  5. Assessment of industrial attitudes toward generic research needs in tribology

    Energy Technology Data Exchange (ETDEWEB)

    Sibley, L.B.; Zlotnick, M.; Levinson, T.M.

    1985-09-01

    Based on extended discussions during visits with 27 companies representing 13 different parts of the tribology industry (such as bearings, lubricants, coatings, powerplants), it is apparent that only a tiny fraction of the large sums publicly reported as R and D expenditures by industry are used to fund generic tribology research. For example, of the greater than $2 B expenditures reported for R and D in the lubricants sector for 1982, the estimated total for generic tribology research was $12 M. This was the largest expenditure in any sector of the tribology industry and one-third of the total of $36 M. In the automotive industry out of a reported expenditure of $4 B, the estimated generic tribology research was $3 M. In some segments of the tribology industry, for example coatings and filters, there were no expenditures on generic research. There was little tendency to improve the state of the art of the tribology industry through long-term investment in generic R and D in ways that would foster innovation and productivity of energy conservation technology. Expenditures were oriented to development of specific commercial and military products, or to basic research focused on unspecified far term results, although useful spin-off of military developments into commercial fields sometimes occurs. There was a broad consensus in the companies visited that existing research results were not always made easily accessible to potential users in industry. The implication was that industry might benefit more if a larger fraction of the funds were devoted to putting the research results into a form design and development engineers could more readily apply. The need for a more effective presentation of research results was expressed with greater urgency at the smaller companies, but there seemed to be a broad consensus on the need for improvement. Recommendations are given.

  6. Biopharmaceutic Risk Assessment of Brand and Generic Lamotrigine Tablets.

    2015-07-06

    The therapeutic equivalence of generic and brand name antiepileptic drugs has been questioned by neurologists and the epilepsy community. A potential contributor to such concerns is pharmaceutical quality. The objective was to assess the biopharmaceutic risk of brand name Lamictal 100 mg tablets and generic lamotrigine 100 mg tablets from several manufacturers. Lamotrigine was characterized in terms of the Biopharmaceutics Classification System (BCS), including aqueous solubility and Caco-2 permeability. A panel of pharmaceutical quality tests was also performed on three batches of Lamictal, three batches of Teva generic, and one batch of each of four other generics: appearance, identity, assay, impurity, uniformity of dosage units, disintegration, dissolution, friability, and loss on drying. These market surveillance results indicate that all brand name and generic lamotrigine 100 mg tablets passed all tests and showed acceptable pharmaceutical quality and low biopharmaceutic risk. Lamotrigine was classified as a BCS class IIb drug, exhibiting pH-dependent aqueous solubility and dissolution. At pH 1.2 and 4.5, lamotrigine exhibited high solubility, whereas lamotrigine exhibited low solubility at pH 6.8, including non-sink dissolution. Lamotrigine showed high Caco-2 permeability. The apparent permeability (Papp) of lamotrigine was (73.7 ± 8.7) × 10(-6) cm/s in the apical-to-basolateral (AP-BL) direction and (41.4 ± 1.6) × 10(-6) cm/s in the BL-AP direction, which were higher than metoprolol's AP-BL Papp of (21.2 ± 0.9) × 10(-6) cm/s and BL-AP Papp of (34.6 ± 4.6) × 10(-6) cm/s. Overall, lamotrigine's favorable biopharmaceutics from a drug substance perspective and favorable quality characteristics from a tablet formulation perspective suggest that multisource lamotrigine tablets exhibit a low biopharmaceutic risk.

    Algebraic geometry, although little explored in signal processing, provides tools that are very convenient for investigating generic properties in a wide range of applications. Generic properties are properties that hold "almost everywhere". We present a set of conditions that are sufficient for demonstrating the generic uniqueness of a certain structured matrix factorization. This set of conditions may be used as a checklist for generic uniqueness in different settings. We discuss two partic...

  12. Generic Scrip Share and the Price of Brand-Name Drugs: The Role of the Consumer

    OpenAIRE

    John A Rizzo; Richard Zeckhauser

    2005-01-01

    Generic drug utilization has risen dramatically, from 19% of scrips in 1984 to 47% in 2001, thus bringing significant direct dollar savings. Generic drug use may also yield indirect savings if it lowers the average price of those brand-name drugs that are still purchased. Prior work indicates - and we confirm - that generic competition does not induce brand-name producers to lower prices. However, consumer choices between generic and brand-name drugs could affect the average price of those br...

The objective of this study was to survey the awareness of generic drugs among outpatients and medical staff and propose methods of promoting the use of generic drugs. Our survey showed that 86.7% of respondents were aware of generic drugs. This is a higher awareness rate than that in a survey of other groups conducted last year. One reason to explain this higher awareness is the recent increase in generic drug advertisements both in newspapers and on television. However, a point of note is that generic drug usage has not increased. Our survey also showed that generic drug awareness was differed widely among age groups, as younger respondents were much more aware of generic drugs than older respondents. Still, about 40% of respondents who were aware of generic drugs did not realize that they were less expensive than name-brand drugs ? including 30% of medical staff. In addition to continuing advertisement of generic drugs in the media, medical doctors and pharmacists should also be encouraged to endorse the use of generic drugs. Furthermore a new system allowing for substitution prescriptions started in April 2008 and consequently pharmacists can now play an important role in promoting the use of generic drugs.

    Full Text Available Introduction: Switching brand name medications to generics is recommended in France in the interest of cost effectiveness but patients and physicians are sometimes not convinced that switching is appropriate. Some antiretroviral (ARV generics (ZDV, 3TC, NVP have been marketed in France since 2013. Materials and Methods: A multicentric cross-sectional survey was performed in September 2013 to evaluate the perception of generics overall and ARV generics in physicians and HIV-infected patients and factors associated to their acceptability. Adult HIV outpatients were asked to complete a self-questionnaire on their perception of generics. Physicians completed a questionnaire on the acceptability of generics and ARV generics. Socio-demographic data, medical history and HIV history were collected. Results: 116 physicians in 33 clinics (68% in University Hospital included 556 patients (France-native 77%, active employment 59%, covered by social Insurance 100%, homosexual/bisexual contamination 47%, median HIV duration 13 years, hepatitis coinfection 16%, on ARV therapy 95%. Overall, patients accepted and had confidence in generics in 76% and 55% of the cases, respectively. Switching ARVs for generics was accepted by 44% of the patients but only by 17% if the pill burden was going to increase. 75% of the physicians would prescribe generics, but this decreased to only 26% if the combo had to be broken. The main reasons for non-prescription of generics were previous brand name ARV-induced side effects (35%, refusal of generics overall (37%, lack of understanding of generics (26%, risk of non-observance of treatment (44%, anxiety (47% and depressive symptoms (25%. In multivariate analysis, factors associated with the acceptability of ARV generics in patients were the use of generics overall (p<0.001 and in physicians, the absence of concern regarding the drug efficacy (p<0.001 and being aware that the patient would accept generics overall (p=0.03 and ARV

  18. Monotone complete C*-algebras and generic dynamics

    CERN Document Server

    Saitô, Kazuyuki

    2015-01-01

    This monograph is about monotone complete C*-algebras, their properties and the new classification theory. A self-contained introduction to generic dynamics is also included because of its important connections to these algebras. Our knowledge and understanding of monotone complete C*-algebras has been transformed in recent years. This is a very exciting stage in their development, with much discovered but with many mysteries to unravel. This book is intended to encourage graduate students and working mathematicians to attack some of these difficult questions. Each bounded, upward directed net of real numbers has a limit. Monotone complete algebras of operators have a similar property. In particular, every von Neumann algebra is monotone complete but the converse is false. Written by major contributors to this field, Monotone Complete C*-algebras and Generic Dynamics takes readers from the basics to recent advances. The prerequisites are a grounding in functional analysis, some point set topology and an eleme...

    2016-05-01

    We study analytic germs in one variable with a parabolic fixed point at the origin, over an ultrametric ground field of positive characteristic. It is conjectured that for such a germ the origin is isolated as a periodic point. Our main result is an affirmative solution of this conjecture in the case of a generic germ with a prescribed multiplier. The genericity condition is explicit: the power series is minimally ramified, i.e. the degree of the first nonlinear term of each of its iterates is as small as possible. Our main technical result is a computation of the first significant terms of a minimally ramified power series. From this we obtain a lower bound for the norm of nonzero periodic points, from which we deduce our main result. As a by-product we give a new and self-contained proof of a characterization of minimally ramified power series in terms of the iterative residue.

    A generic process has been developed to grow nearly defect-free arrays of (heterostructured) InP and GaP nanowires. Soft nano-imprint lithography has been used to pattern gold particle arrays on full 2 inch substrates. After lift-off organic residues remain on the surface, which induce the growth of additional undesired nanowires. We show that cleaning of the samples before growth with piranha solution in combination with a thermal anneal at 550 deg. C for InP and 700 deg. C for GaP results in uniform nanowire arrays with 1% variation in nanowire length, and without undesired extra nanowires. Our chemical cleaning procedure is applicable to other lithographic techniques such as e-beam lithography, and therefore represents a generic process.

    Photonic integrated circuits (PICs) are considered as the way to make photonic systems or subsystems cheap and ubiquitous. PICs still are several orders of magnitude more expensive than their microelectronic counterparts, which has restricted their application to a few niche markets. Recently, a novel approach in photonic integration is emerging which will reduce the R&D and prototyping costs and the throughput time of PICs by more than an order of magnitude. It will bring the application of PICs that integrate complex and advanced photonic functionality on a single chip within reach for a large number of small and larger companies and initiate a breakthrough in the application of Photonic ICs. The paper explains the concept of generic photonic integration technology using the technology developed by the COBRA research institute of TU Eindhoven as an example, and it describes the current status and prospects of generic InP-based integration technology.

  2. Sensor Fault Tolerant Generic Model Control for Nonlinear Systems

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    A modified Strong Tracking Filter (STF) is used to develop a new approach to sensor fault tolerant control. Generic Model Control (GMC) is used to control the nonlinear process while the process runs normally because of its robust control performance. If a fault occurs in the sensor, a sensor bias vector is then introduced to the output equation of the process model. The sensor bias vector is estimated on-line during every control period using the STF. The estimated sensor bias vector is used to develop a fault detection mechanism to supervise the sensors. When a sensor fault occurs, the conventional GMC is switched to a fault tolerant control scheme, which is, in essence, a state estimation and output prediction based GMC. The laboratory experimental results on a three-tank system demonstrate the effectiveness of the proposed Sensor Fault Tolerant Generic Model Control (SFTGMC) approach.

    1986-07-01

    Pacific Northwest Laboratory developed a method for forecasting potential locations and startup sequences of nuclear power plants that will be required in the future but have not yet been specifically identified by electric utilities. Use of the method results in numerical ratings for potential nuclear power plant sites located in each of the 10 federal energy regions. The rating for each potential site is obtained from numerical factors assigned to each of 5 primary siting characteristics: (1) cooling water availability, (2) site land area, (3) power transmission land area, (4) proximity to metropolitan areas, and (5) utility plans for the site. The sequence of plant startups in each federal energy region is obtained by use of the numerical ratings and the forecasts of generic nuclear power plant startups obtained from the EIA Middle Case electricity forecast. Sites are assigned to generic plants in chronological order according to startup date.

    Although the field of cancer immunotherapy is intensively investigated, there is still a need for generic strategies that allow easy, mild and efficient formulation of vaccine antigens. Here we report on a generic polymer-protein ligation strategy to formulate protein antigens into reversible polymeric conjugates for enhanced uptake by dendritic cells and presentation to CD8 T-cells. A N-hydroxypropylmethacrylamide (HPMA)-based copolymer was synthesized via RAFT polymerization followed by introduction of pyridyldisulfide moieties. To enhance ligation efficiency to ovalbumin, which is used as a model protein antigen, protected thiols were introduced onto lysine residues and deprotected in situ in the presence of the polymer. The ligation efficiency was compared for both the thiol-modified versus unmodified ovalbumin, and the reversibility was confirmed. Furthermore, the obtained nanoconjugates were tested in vitro for their interaction and association with dendritic cells, showing enhanced cellular uptake and antigen cross-presentation to CD8 T-cells.

    Kota, Ramachandra; Gibbins, Nicholas; Jennings, Nicholas R.

    Autonomic computing is being advocated as a tool for managing large, complex computing systems. Specifically, self-organisation provides a suitable approach for developing such autonomic systems by incorporating self-management and adaptation properties into large-scale distributed systems. To aid in this development, this paper details a generic problem-solving agent organisation framework that can act as a modelling and simulation platform for autonomic systems. Our framework describes a set of service-providing agents accomplishing tasks through social interactions in dynamically changing organisations. We particularly focus on the organisational structure as it can be used as the basis for the design, development and evaluation of generic algorithms for self-organisation and other approaches towards autonomic systems.

    Under the Abbreviated New Drug Application pathway, a proposed generic salmon calcitonin nasal spray is required to demonstrate pharmaceutical equivalence and bioequivalence to the brand-name counterpart or the reference listed drug. This review discusses two important aspects of pharmaceutical equivalence for this synthetic peptide nasal spray product. The first aspect is drug substance sameness, in which a proposed generic salmon calcitonin product is required to demonstrate that it contains the same active ingredient as that in the brand-name counterpart. The second aspect is comparability in product- and process-related factors that may influence immunogenicity (i.e., peptide-related impurities, aggregates, formulation, and leachates from the container/closure system). The comparability of these factors helps to ensure the product safety, particularly with respect to immunogenicity. This review also highlights the key features of in vitro and/or in vivo studies for establishing bioequivalence for a solution nasal spray containing a systemically acting salmon calcitonin.

    Kim, Duk-Hyun; Kim, Cheolhan

    Performance measurement (PM) is essential for managing networked enterprises (NEs) because it greatly affects the effectiveness of collaboration among members of NE.PM in NE requires somewhat different approaches from PM in a single enterprise because of heterogeneity, dynamism, and complexity of NE’s. This paper introduces a generic framework of PM in NE (we call it NEPM) based on the Balanced Scorecard (BSC) approach. In NEPM key performance indicators and cause-and-effect relationships among them are defined in a generic strategy map. NEPM could be applied to various types of NEs after specializing KPIs and relationships among them. Effectiveness of NEPM is shown through a case study of some Korean NEs.

    Full Text Available The paper focuses on the description of film musicals as a subgenre of the genre family of musicals. Their dramatic structure is examined in terms of the generic elements that constitute the progression of a story expressed through the combination of spoken dialogue, songs and dance. The function of songs in the generic structure of film musicals is examined in the framework of the systemic-functional theory of register and genre. Special attention is given to the role of songs in the unfolding of the narrative. The theoretical observations about the role of songs in the register and genre of film musicals are then illustrated with an analysis of the use of songs in the TV musical High School Musical 2.

    2014-01-01

    Full Text Available Generic skills include transferable skills which contribute to general work skills of an individual and can be used in different jobs and work organizations. Situational assessment is considered to be the best approach in gathering information on generic skills and adaptive behavior in persons with intellectual disabilities (ID, since it enables systematic observation of work related behavior. The aim of this paper is to determine the relation of the degree of generic skills acquisition with regard to the level of intellectual functioning of students with mild intellectual disability (MID. The sample consists of 120 examinees undergoing professional training, of both genders, with IQ between 51 and 70. The sample is divided in two groups: the group with higher level of intellectual functioning (IQ 61-70 which includes 75 examinees (62.5%, and the group lower level of intellectual functioning (IQ 51-60 which includes 45 (37.5% examinees. The results of the adapted Situational assessment form test (Cline et al., 2005 indicate the statistically significant difference between the examinees with different levels of intellectual functioning. The examinees with higher level of intellectual functioning show greater interest in work, they perform the assigned tasks for a longer period of time, they adapt to changes while working more easily, and use the acquired work skills appropriately. They are more independent and mobile during training, they initiate a greater number of social interactions, behave more appropriately in work environment, and manage to control fatigue and stress while working. Information on generic skills can be used for developing individual plan of employment of persons with MID and/or for determining the model of employment, adaptation of work place and temporary placement.

    Results: All the commercial brands of metformin were stable under all storage conditions for up to 30 days. They retained more than 90% of the initial quantity of the active drug, with pH of 7.4 ± 0.3. Conclusion: extemporaneous formulations of metformin can be made with both the innovative drug and with generics; money can be saved, with the certainty that they will retain their physicochemical properties.

  3. Do higher-priced generic medicines enjoy a competitive advantage under reference pricing?

    Science.gov (United States)

    Puig-Junoy, Jaume

    2012-11-01

    In many countries with generic reference pricing, generic producers and distributors compete by means of undisclosed discounts offered to pharmacies in order to reduce acquisition costs and to induce them to dispense their generic to patients in preference over others. The objective of this article is to test the hypothesis that under prevailing reference pricing systems for generic medicines, those medicines sold at a higher consumer price may enjoy a competitive advantage. Real transaction prices for 179 generic medicines acquired by pharmacies in Spain have been used to calculate the discount rate on acquisition versus reimbursed costs to pharmacies. Two empirical hypotheses are tested: the discount rate at which pharmacies acquire generic medicines is higher for those pharmaceutical presentations for which there are more generic competitors; and, the discount rate at which pharmacies acquire generic medicines is higher for those pharmaceutical forms for which the consumer price has declined less in relation to the consumer price of the brand drug before generic entry (higher-priced generic medicines). An average discount rate of 39.3% on acquisition versus reimbursed costs to pharmacies has been observed. The magnitude of the discount positively depends on the number of competitors in the market. The higher the ratio of the consumer price of the generic to that of the brand drug prior to generic entry (i.e. the smaller the price reduction of the generic in relation to the brand drug), the larger the discount rate. Under reference pricing there is intense price competition among generic firms in the form of unusually high discounts to pharmacies on official ex-factory prices reimbursed to pharmacies. However, this effect is highly distorting because it favours those medicines with a higher relative price in relation to the brand price before generic entry.

  4. Origami building blocks: Generic and special four-vertices

    Waitukaitis, Scott; van Hecke, Martin

    2016-02-01

    Four rigid panels connected by hinges that meet at a point form a four-vertex, the fundamental building block of origami metamaterials. Most materials designed so far are based on the same four-vertex geometry, and little is known regarding how different geometries affect folding behavior. Here we systematically categorize and analyze the geometries and resulting folding motions of Euclidean four-vertices. Comparing the relative sizes of sector angles, we identify three types of generic vertices and two accompanying subtypes. We determine which folds can fully close and the possible mountain-valley assignments. Next, we consider what occurs when sector angles or sums thereof are set equal, which results in 16 special vertex types. One of these, flat-foldable vertices, has been studied extensively, but we show that a wide variety of qualitatively different folding motions exist for the other 15 special and 3 generic types. Our work establishes a straightforward set of rules for understanding the folding motion of both generic and special four-vertices and serves as a roadmap for designing origami metamaterials.

    Shafiq, Omair

    Semantic Web Services research has gained momentum over the last few Years and by now several realizations exist. They are being used in a number of industrial use-cases. Soon software developers will be expected to use this infrastructure to build their B2B applications requiring dynamic integration. However, there is still a lack of guidelines for the evaluation of tools developed to realize Semantic Web Services and applications built on top of them. In normal software engineering practice such guidelines can already be found for traditional component-based systems. Also some efforts are being made to build performance models for servicebased systems. Drawing on these related efforts in component-oriented and servicebased systems, we identified the need for a generic evaluation model for Semantic Web Services applicable to any realization. The generic evaluation model will help users and customers to orient their systems and solutions towards using Semantic Web Services. In this chapter, we have presented the requirements for the generic evaluation model for Semantic Web Services and further discussed the initial steps that we took to sketch such a model. Finally, we discuss related activities for evaluating semantic technologies.

    Due to a packaging error that left white placebo pills in place of active pills, Gynex Inc. has had to recall 325,000 packages of generic oral contraceptives (OC), a mistake that the company insists has not affected consumers. Company vice president Stephen M. Simes says that although the majority of the defective packages remain in the possession of wholesalers and chain store warehouses, some had been shipped to pharmacies. But presently, it seems that none have reached consumers. Recently entering the generic OC market, the company's packaging error involved its first shipment of Gynex 1/35E and Gynex 0.5/35 in 28-day packs. These two generics are copy products on ON 1/35, made by Ortho Pharmaceutical, Modicon/Brevicon, made by Ortho Pharmaceutical and Syntex Laboratories--two widely used OCs. While the company is still investigating the incident, Simes explains that the company is enacting changes in the packaging procedures and is considering alterations in machinery and in quality control. The error will probably represent a financial loss for the company, and it will delay Gynex's entry into the contraceptive market. But the California-based company plans to press ahead, having already filed marketing applications for 5 additional low-dose OC formulations.

    The purpose of this generic aging lessons learned (GALL) review is to provide a systematic review of plant aging information in order to assess materials and component aging issues related to continued operation and license renewal of operating reactors. Literature on mechanical, structural, and thermal-hydraulic components and systems reviewed consisted of 97 Nuclear Plant Aging Research (NPAR) reports, 23 NRC Generic Letters, 154 Information Notices, 29 Licensee Event Reports (LERs), 4 Bulletins, and 9 Nuclear Management and Resources Council Industry Reports (NUMARC IRs) and literature on electrical components and systems reviewed consisted of 66 NPAR reports, 8 NRC Generic Letters, 111 Information Notices, 53 LERs, 1 Bulletin, and 1 NUMARC IR. More than 550 documents were reviewed. The results of these reviews were systematized using a standardized GALL tabular format and standardized definitions of aging-related degradation mechanisms and effects. The tables are included in volume s 1 and 2 of this report. A computerized data base has also been developed for all review tables and can be used to expedite the search for desired information on structures, components, and relevant aging effects. A survey of the GALL tables reveals that all ongoing significant component aging issues are currently being addressed by the regulatory process. However, the aging of what are termed passive components has been highlighted for continued scrutiny. This report consists of Volume 2, which consists of the GALL literature review tables for the NUMARC Industry Reports reviewed for the report.

    In vitro dissolution testing is an important tool used for development and approval of generic dosage forms. The objective of this article is to summarize how dissolution testing is used for the approval of safe and effective generic drug products in the United States (US). Dissolution testing is routinely used for stability and quality control purposes for both oral and non-oral dosage forms. The dissolution method should be developed using an appropriate validated method depending on the dosage form. There are several ways in which dissolution testing plays a pivotal role in regulatory decision-making. It may be used to waive in vivo bioequivalence (BE) study requirements, as BE documentation for Scale Up and Post Approval Changes (SUPAC), and to predict the potential for a modified-release (MR) drug product to dose-dump if co-administered with alcoholic beverages. Thus, in vitro dissolution testing plays a major role in FDA's efforts to reduce the regulatory burden and unnecessary human studies in generic drug development without sacrificing the quality of the drug products.

    The cost of HIV care in European countries is high. Direct medical costs, in France, have been estimated at 500,000 Euros per patient's lifetime (20,000 Euros/year/patient). Overall, 73% of these costs are related to antiretroviral treatments. In the current financial crisis context, some European countries are beginning to make economic decisions on the drugs to be used. These approaches are likely to become more frequent. It is obviously essential to prescribe the most effective, appropriate, best tolerated, and easy-to-use antiretroviral treatments to patients. However, while taking the above into consideration, and if various treatment options or combinations are available, cost should also be considered in the treatment choice. One may thus reflect on the use of generic antiretroviral agents as they have just been launched in France. We aimed to review the cost and cost-effectiveness of generic antiretroviral drugs and to review treatment strategies other than generic drugs that could help reduce HIV-related costs. HIV clinicians should consider treatment costs to avoid any future coercive measures.

    Full Text Available BACKGROUND: The transition of the generic/biotechnology industry to innovation by investing in innovative R&D will enhance business expertise in biopharmaceutical development and manufacturing. The major impact of this evolution is on patient access to treatment and savings for the health care systems. OBJECTIVES: The aim of this paper is to investigate the innovative aspect of biosimilar and biobetter products, manufactured by some big generic companies. We will also try to explore the innovative business strategy, implementing this high risk product differentiation policy. METHODS: This qualitative research is conducted by a series of interviews with CEOs, physicians, and academics in different countries. The qualitative data obtained were analyzed by Nvivo9.2 software. A literature review has also contributed to our key findings. RESULTS: The results show that switching into biosimilars/biobetters is an innovative strategic choice, approved by some big generic pharmaceutical companies. The biosimilar/biobetter products can be considered innovative because of their value added quality. CONCLUSION: Expanding the product portfolio to biosimilars/biobetter can be considered as a long run strategy in the innovative business plans aiming to ensure the market access. Patients and their access to better treatments are major components of these innovative business models.

    The success of cost containment with generic drugs is based on consumer's willingness to accept substitution. This investigation reveals 3 major themes that can explain attitudes of patients towards generics: 1) personal beliefs and knowledge (coming from the media issues, family, friends) are fragmented and sometimes erroneous, with a background of suspicion on the quality of the generics; 2) relation with the prescriber (indirectly pharmacist) is central to build up patient's trust; suspicious professionals generate an anxious patient; 3) previous experience from the consumer with generics. Starting from patients' experiences and beliefs allows to anticipate their resistance to the generic and to adapt drug prescription choices.

    Policy Points: Our study indicates that there are opportunities for cost savings in generic drug markets in Europe and the United States. Regulators should make it easier for generic drugs to reach the market. Regulators and payers should apply measures to stimulate price competition among generic drugmakers and to increase generic drug use. To meaningfully evaluate policy options, it is important to analyze historical context and understand why similar initiatives failed previously. Rising drug prices are putting pressure on health care budgets. Policymakers are assessing how they can save money through generic drugs. We compared generic drug prices and market shares in 13 European countries, using data from 2013, to assess the amount of variation that exists between countries. To place these results in context, we reviewed evidence from recent studies on the prices and use of generics in Europe and the United States. We also surveyed peer-reviewed studies, gray literature, and books published since 2000 to (1) outline existing generic drug policies in European countries and the United States; (2) identify ways to increase generic drug use and to promote price competition among generic drug companies; and (3) explore barriers to implementing reform of generic drug policies, using a historical example from the United States as a case study. The prices and market shares of generics vary widely across Europe. For example, prices charged by manufacturers in Switzerland are, on average, more than 2.5 times those in Germany and more than 6 times those in the United Kingdom, based on the results of a commonly used price index. The proportion of prescriptions filled with generics ranges from 17% in Switzerland to 83% in the United Kingdom. By comparison, the United States has historically had low generic drug prices and high rates of generic drug use (84% in 2013), but has in recent years experienced sharp price increases for some off-patent products. There are policy

    This meta-analysis aimed to compare the efficacy and adverse events, either serious or mild/moderate, of all generic versus brand-name cardiovascular medicines. We searched randomized trials in MEDLINE, Scopus, EMBASE, Cochrane Controlled Clinical Trial Register, and ClinicalTrials.gov (last update December 1, 2014). Attempts were made to contact the investigators of all potentially eligible trials. Two investigators independently extracted and analyzed soft (including systolic blood pressure, LDL cholesterol, and others) and hard efficacy outcomes (including major cardiovascular adverse events and death), minor/moderate and serious adverse events. We included 74 randomized trials; 53 reported ≥1 efficacy outcome (overall sample 3051), 32 measured mild/moderate adverse events (n = 2407), and 51 evaluated serious adverse events (n = 2892). We included trials assessing ACE inhibitors (n = 12), anticoagulants (n = 5), antiplatelet agents (n = 17), beta-blockers (n = 11), calcium channel blockers (n = 7); diuretics (n = 13); statins (n = 6); and others (n = 3). For both soft and hard efficacy outcomes, 100 % of the trials showed non-significant differences between generic and brand-name drugs. The aggregate effect size was 0.01 (95 % CI -0.05; 0.08) for soft outcomes; -0.06 (-0.71; 0.59) for hard outcomes. All but two trials showed non-significant differences in mild/moderate adverse events, and aggregate effect size was 0.07 (-0.06; 0.20). Comparable results were observed for each drug class and in each stratified meta-analysis. Overall, 8 serious possibly drug-related adverse events were reported: 5/2074 subjects on generics; 3/2076 subjects on brand-name drugs (OR 1.69; 95 % CI 0.40-7.20). This meta-analysis strengthens the evidence for clinical equivalence between brand-name and generic cardiovascular drugs. Physicians could be reassured about prescribing generic cardiovascular drugs, and health care organization about endorsing their wider

    Generic drugs are interchangeable with original proprietary drugs, as they have the same active pharmaceutical ingredients, dosage forms, strength, quality, indications, effects, directions, and dosage. The cost of generic drugs is lower than original drugs, because the developmental cost is lower. The expansion of medical expenses is an important issue in many countries, including Japan, the USA, and Europe, and promotion of generic drugs has been demanded to solve this issue in Japan. Generic drug approval review in Japan is conducted by the Pharmaceuticals and Medical Devices Agency (PMDA), which reviews the equivalence of the original drugs from the viewpoint of quality, efficacy, and safety, based on documentation submitted by the generic drug applicants. However, the details of the generic drug review in Japan have not been reported. In this report, we introduce the application types, the number of applications and approvals, and the review timeline of generic drugs in Japan. In addition, we discuss recent consultations and future prospects.

    Generic agents play a crucial role in reducing the cost of medical care in many countries. However, the therapeutic equivalence remains a great concern. Our study aims to assess the in vitro antimicrobial activity and bioequivalence between generic and brand-name levofloxacin. Enantiomeric purity test, dissolution test, and in vitro antimicrobial susceptibility against seven clinically important pathogens by the agar dilution method were employed to assess the similarity between four generic products and brand-name levofloxacin (Daiichi Sankyo). All the generic and brand-name levofloxacin passed enantiomeric purity test. The results of dissolution tests were not similar among the generic products and the brand-name levofloxacin. Compared with the generic products, the brand-name levofloxacin had the smallest mean variations (-25% to 13%) with reference standard (United States Pharmacopeia levofloxacin Reference Standards). Variations were observed particularly in dissolution profiles and in vitro activity between generic products and brand-name levofloxacin.

    Full Text Available Introduction One of the main targets of planners, decision makers and governments is increasing society health with promotion and production of suitable and healthy food. One of the basic commodities that have important role in satisfaction of required human food is milk. So, some part of government and producer healthy budget allocate to milk consumption promotion by using generic advertising. If effectiveness of advertising budget on profitability is more, producer will have more willing to spend for advertising. Determination of optimal generic advertising budget is one of important problem in managerial decision making in producing firm as well as increase in consumption and profit and decrease in wasting and non-optimality of budget. Materials and Methods: In this study, optimal generic advertising budget intensity index (advertising budget share of production cost was estimated under two different scenarios by using equilibrium replacement model. In equilibrium replacement model, producer surplus are maximized in respect to generic advertising in retail level. According to market where two levels of farm and processing before retail exist and there is trade in farm and retail level, we present different models. Fixed and variable proportion hypothesis is another one. Finally, eight relations are presented for determination of milk generic advertising optimum budget. So, we use data from several resources such as previous studies, national (Iran Static center and international institute (Fao formal data and own estimation. Because there are several estimations in previous studies, we identify some scenarios (in two general scenarios for calculation of milk generic advertising optimum budget. Results and Discussion: Estimation of milk generic advertising optimum budget in scenario 1 shows that in case of one market level, fixed supplies and no trade, optimum budget is 0.4672539 percent. In case of one market level and no trade, optimum

    After the expiry of patents for originator medicines, generic medicines can enter the market, and price competition may occur. This process generates savings to the healthcare payer and to patients, but knowledge about the factors affecting price competition in the pharmaceutical market following patent expiry is still limited. This study aimed to investigate the relationship between the market share of generic medicines and the change of the medicine price level in European off-patent markets. Data on medicine volumes and values for 35 active substances were purchased from IMS Health. Ex-manufacturer prices were used, and the analysis was limited to medicines in immediate-release, oral, solid dosage forms. Countries included were Austria, Belgium, Denmark, Germany, France, Italy, the Netherlands, Spain, Sweden and the UK, which constitute a mix of countries with low and high generic medicines market shares. Data were available from June 2002 until March 2007. Market volume has risen in both high and low generic market share countries (+29.27% and +27.40%, respectively), but the cause of the rise is different for the two markets. In low generic market share countries, the rise was caused by the increased use of generic medicines, while in high market share countries, the rise was driven by the increased use of generic medicines and a shift of use from originator to generic medicines. Market value was substantially decreased in high generic market share countries (-26.6%), while the decrease in low generic market share countries was limited (-0.06%). In high generic market share countries, medicine prices dropped by -43.18% versus -21.56% in low market share countries. The extent to which price competition from generic medicines leads to price reductions appears to vary according to the market share of generic medicines. High generic market share countries have seen a larger decrease in medicine prices than low market share countries.

    Full Text Available A range of factors are believed to exert a negative influence on opinions of physicians about generic drugs.The aim of this study was to survey the opinions of primary care doctors on generics, and determine the factors which may affect them. A questionnaire comprising thirty eight questions was distributed among primary care doctors working in seventy out-patient clinics of the Lodzkie province, Poland, during the period of January 1, 2010 – December 31, 2010. A total of170 of 183 participants completed the survey (average age 48.5; 70.0% women: a 92.9%response rate. While 38.8% of physicians claimed that generics were worse than brand name drugs, 54.1% considered them to be better. However, 36.5% of the doctors did not choose generics for their own use. Two key opinions were identified among the responses concerning the effectiveness of generic drugs: use of generic drugs by the physician (p<0.001, and their opinion that pharmacists do inform patients about generic drugs (p<0.05. Although existing evidence confirms that generic and brand name drugs are equally effective, many physicians doubt this, which prevents them from being used as cost effective drug therapy. In order to increase healthcare savings through the use of generics, these factors should be addressed: for example, convincing a physician to adopt generics for personal use may be an efficient way to support more cost effective treatment of his patients.

    Specifications in the U.S. Code of Federal Regulations for the color additive D&C Green No. 8 (Colour Index No. 59040) limit the levels of the subsidiary colors 1,3,6-pyrenetrisulfonic acid trisodium salt (P3S) and 1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt (P4S). The present paper describes a comparative study of two possible methods to replace the currently used multi-step TLC/spectrophotometry method of separating and quantifying the minor components P3S and P4S in G8. One of the new approaches uses conventional high-performance liquid chromatography (HPLC) and the other, derivative spectrophotometry. While the derivative spectrophotometric method was shown to be inadequate for the analysis of minor components overwhelmed by components of much higher concentration, the HPLC method was proven highly effective. The closely related, very polar compounds P3S and P4S were separated by the new HPLC method in less than 4 min using a conventional HPLC instrument. P3S and P4S were quantified by using five-point calibration curves with data points that ranged from 0.45 to 7.63% and from 0.13 to 1.82%, by weight, for P3S and P4S, respectively. The HPLC method was applied to the analysis of test portions from 20 batches of D&C Green No. 8 submitted to the U.S. Food and Drug Administration for certification.
