Full Text Available Abstract Background Screening women for Chlamydia trachomatis infection in developing countries is highly desirable because of asymptomatic infection. The existing diagnostic methods in developing countries are not effective and their sensitivity fall below 45.0% which leads to further spread of infection. There is an urgent need for improved and cost effective diagnostic tests that will reduce the burden of sexually transmitted infections in the developing world. Methods Prevalence of C. trachomatis infection among women visiting gynaecology department of Hindu Rao hospital in Delhi, India was determined using Roche Amplicor Multi Well Plate kit (MWP as well as using in-house PCR assay. We used 593 endocervical swabs for clinical evaluation of the in-house developed assay against Direct Fluorescence Assay (DFA; Group I n = 274 and Roche Amplicor MWP kit (Group II, n = 319 samples and determined the sensitivity, specificity, positive predictive value (PPV, negative predictive value (NPV of the in-house developed assay. Results We detected 23.0% positive cases and there was a higher representation of women aged 18-33 in this group. An in-house PCR assay was developed and evaluated by targeting unique sequence within the gyrA gene of C. trachomatis. Specificity of the reaction was confirmed by using genomic DNA of human and other STI related microorganisms as template. Assay is highly sensitive and can detect as low as 10 fg of C. trachomatis DNA. The resolved sensitivity of in-house PCR was 94.5% compared with 88.0% of DFA assay. The high specificity (98.4% and sensitivity (97.1% of the in-house assay against Roche kit and availability of test results within 3 hours allowed for immediate treatment and reduced the risk of potential onward transmission. Conclusions The in-house PCR method is cost effective (~ 20.0% of Roche assay and hence could be a better alternative for routine diagnosis of genital infection by C. trachomatis to facilitate

Rapid quantitative molecular methods are very important for the diagnosis of human immunodeficiency virus (HIV) infections, assessment of prognosis and follow up. The purpose of this study was to compare and evaluate the performances of conventional manual extraction method and automated MagNA Pure system, for the nucleic acid isolation step which is the first and most important step in molecular diagnosis of HIV infections. Plasma samples of 35 patients in which anti-HIV antibodies were found as positive by microparticule enzyme immunoassay and confirmed by immunoblotting method, were included in the study. The nucleic acids obtained simultaneously by manual isolation kit (Cobas Amplicor, HIV-1 Monitor Test, version 1.5, Roche Diagnostics) and automated system (MagNA Pure LC Total Nucleic Acid Isolation Kit, Roche Diagnostics), were amplified and detected in Cobas Amplicor (Roche Diagnostics) instrument. Twenty three of 35 samples (65.7%) were found to be positive, and 9 (25.7%) were negative by both of the methods. The agreement between the methods were detected as 91.4%, for qualitative results. Viral RNA copies detected by manual and MagNA Pure isolation methods were found between 76.0-7.590.000 (mean: 487.143) and 113.0-20.300.0000 (mean: 2.174.097) copies/ml, respectively. When both of the overall and individual results were evaluated, the number of RNA copies obtained with automatized system, were found higher than the manual method (p<0.05). Three samples which had low numbers of nucleic acids (113, 773, 857, respectively) with MagNA Pure, yielded negative results with manual method. In conclusion, the automatized MagNA Pure system was found to be a reliable, rapid and practical method for the isolation of HIV-RNA.

Through tidal dissipation in a slowly spinning host star, the orbits of many hot Jupiters may decay down to the Roche limit. We expect that the ensuing mass transfer will be stable in most cases. Using detailed numerical calculations, we find that this evolution is quite rapid, potentially leading to the complete removal of the gaseous envelope in a few gigayears, and leaving behind an exposed rocky core (a {sup h}ot super-Earth{sup )}. Final orbital periods are quite sensitive to the details of the planet's mass-radius relation and to the effects of irradiation and photo-evaporation, but could be as short as a few hours or as long as several days. Our scenario predicts the existence of planets with intermediate masses ({sup h}ot Neptunes{sup )} that should be found precisely at their Roche limit and in the process of losing mass through Roche lobe overflow. The observed excess of small single-planet candidate systems observed by Kepler may also be the result of this process. If so, the properties of their host stars should track those of the hot Jupiters. Moreover, the number of systems that produced hot Jupiters could be two to three times larger than one would infer from contemporary observations.

The small hydropower plant (SHPP) project 'PCH Roches' is planned to be built in Roches, a small village located in the Jura region of the canton of Bern. The goal of this undertaking is to reactivate a site with hydro potential of the river Birs on a section that was already well exploited by some ancient SHPP (since 1953 or probably even earlier). Several modifications were performed on this plant over the years; not all contributed positively on its production figures. Following a transfer of the water rights in 1987, claims became loud against the owner to perform maintenance on the river banks and to modify the weir such that a free passage for the fishes will be granted. Those issues contributed to inflate a conflict which ended in the repeal of the water rights and a total plant shut down in 2001. The new project plans to reuse the existing pen stock and to carry out some refurbishing activities to grant security and better performance. The weir and the intake structure are also redesigned such that the water storage can be somewhat raised for normal operation; a weir gate will however allow to better discharge the river in flood situations. A new turbine house will be erected at the current location where the tail water pen stock rejoins the river. Hence, the existing old turbine house will be obsolete and the upper and lower pen stock sections are to be linked with each other. Limited by the existing pen stock size, the new plant is expected to produce some 50 kW power and 362,000 kWh/year. This represents an increase in energy generation of around 200% compared with the ancient SHPP. Gross head is 5.38 m, net head 4.12 m with a turbine flow of at least 1.6 m{sup 3}/s. The expected energy sales price applicable to this project reaches about 0.17 CHF/kWh as per the current tariffs set by the grid owner. This project calls for the building of a state-of-the-art SHPP. It will avoid the total dismantling of the existing works to take place and allow

Spiral shocks on a Roche lobe overflow in a semi-detached binary system

Sawada, K.; Matsuda, T.; Hachisu, I.

1986-01-01

Two-dimensional hydrodynamic calculations of a Roche lobe overflow in a semi-detached binary system with a mass ratio of unity are carried out. The region of the computation covers both a mass-losing star filling its critical Roche lobe and a mass-accreting compact star. Gas ejected from the mass-losing star with specified energy flows through the L1 point to form an elephant trunk and an accretion ring. It is found that spiral-shaped shocks are formed on the accretion ring. It is suggested that the gas in the accretion ring loses angular momentum at the shocks and spirals in towards the compact star even without viscosity. (author)

HIV-1 viral load (VL) testing is important to predict viral progression and to monitor the response to antiretroviral therapy. New HIV-1 VL tests are continuously introduced to the market. Their performance is usually compared to Abbott and/or Roche HIV-1 VL assays, as reference. The Xpert HIV-1 VL test was recently introduced, but its performance compared to Roche has not been sufficiently studied. To compare the Xpert assay with Roche and to assess its use in the HIV clinical laboratory. A total of 383 plasma samples of HIV-1 infected patients previously tested by Roche, were retrospectively tested by Xpert to determine concordance between the two assays. Samples included a diversity of HIV-1 subtypes and a wide range of VLs. There was a high concordance between the two assays, except for a CRF02_AG subtype variant with high VL titters, that was detected by Roche but undetected by Xpert. The 5' long terminal repeat gene region of this virus, targeted by the Xpert assay, was amplified and sequenced. A 25 nucleotide insert was identified, but was unmatched to any known sequences of HIV-1. This particular insert, however could not explain the false-negativity by the Xpert assay. This study underlines the challenge to routine VL testing due to the high genetic diversity of HIV-1. Clinicians should, therefore be advised that a negative VL in cases where the clinical picture does not match the laboratory report, might in fact be, a false-negative result of the VL assay.

We give an orbifold Riemann-Roch formula in closed form for the Hilbert series of a quasismooth polarized n-fold (X,D), under the assumption that X is projectively Gorenstein with only isolated orbifold points. Our formula is a sum of parts each of which is integral and Gorenstein symmetric of the same canonical weight; the orbifold parts are called ice cream functions. This form of the Hilbert series is particularly useful for computer algebra, and we illustrate it on examples of {K3} surfaces and Calabi-Yau 3-folds. These results apply also with higher dimensional orbifold strata (see [1] and [2]), although the precise statements are considerably trickier. We expect to return to this in future publications.

Many exoplanets have now been detected in orbits with ultra-short periods very close to the Roche limit. Building upon our previous work, we study the possibility that mass loss through Roche lobe overflow (RLO) may affect the evolution of these planets, and could possibly transform a hot Jupiter into a lower-mass planet (hot Neptune or super-Earth). We focus here on systems in which the mass loss occurs slowly (“stable mass transfer” in the language of binary star evolution) and we compute their evolution in detail with the binary evolution code Modules for Experiments in Stellar Astrophysics. We include the effects of tides, RLO, irradiation, and photo-evaporation (PE) of the planet, as well as the stellar wind and magnetic braking. Our calculations all start with a hot Jupiter close to its Roche limit, in orbit around a Sun-like star. The initial orbital decay and onset of RLO are driven by tidal dissipation in the star. We confirm that such a system can indeed evolve to produce lower-mass planets in orbits of a few days. The RLO phase eventually ends and, depending on the details of the mass transfer and on the planetary core mass, the orbital period can remain around a few days for several Gyr. The remnant planets have rocky cores and some amount of envelope material, which is slowly removed via PE at a nearly constant orbital period; these have properties resembling many of the observed super-Earths and sub-Neptunes. For these remnant planets, we also predict an anti-correlation between mass and orbital period; very low-mass planets (M{sub pl} ≲ 5 M{sub ⊕}) in ultra-short periods (P{sub orb} < 1 day) cannot be produced through this type of evolution.

Resumen

Algunos proyectos, como el Dusty relief/B‐mu (2002 de François Roche demuestran como edificios complejos, que toman distancia desde los modelos mecanicistas para referirse a nuevos paradigmas, se pueden interpretar y comprenderse  mejor gracias a un análisis perceptivo que acerca el proyecto de arquitectura a cuestiones como la relación psicológica del hombre con la arquitectura, el miedo al espacio, y las  patologías  vinculadas a la percepción y a las neurosis modernas.
En este caso, aparte de las repercusiones que la fachada de  polvo podría tener en el ámbito de la ecología urbana, es interesante analizar algunos aspectos ligados a la dicotomía  entre forma externa y volúmenes internos para la que François Roche cita como referencia el raumplan de Adolf Loos, pero que presenta motivos para una reflexión vinculada a los aspectos  perceptivos.
El artículo trata de analizar como François Roche proyecta sus edificios extremando la dicotomía entre interior/visual y  exterior/táctil, desarrollando así una nueva relación con el lugar. Roche diseña la fachada exterior del B‐mu autoimponiéndose  una limitación del sentido de la vista, a favor de una dimensión háptica del proyecto y lo hace envolviendo los ámbitos arquitectónicos más familiares de una interfaz abstracta y táctil.

Abstract

Some projects such as Dusty relief/B‐mu (2002 by François  Roche demonstrate how complex buildings, which distance themselves from the mechanicist models in order to refer  themselves to new paradigms, can be better understood and interpreted thanks to a perceptive analysis.
This analysis brings the architectural project closer to matters  such as man’s psychological relationship to Architecture, the fear of space

Homage to Jean Roche

2010-01-01

It was with deep sadness that we learnt that Jean Roche had died. Jean was one of those quietly efficient and conscientious pillars of our community who beaver away unobtrusively for decades and make such a contribution to building CERN. An expert in thermal engineering, he left his mark on many buildings on the Meyrin and Prévessin sites. At the time of the LEP project at the beginning of the 1980s he was in charge of defining the principles of the ventilation systems for the new accelerator. Through his design studies and the calls for tenders that he launched, he developed these high-performance state-of-the-art installations which not only made LEP’s successes possible but also served as benchmarks for the fundamental principles underpinning the design of the LHC ventilation system. Jean always liked to surround himself with young people and during the years of his stewardship the design office was a splendid training ground. Despite his responsibilities, Jean was always keen t...

Human papillomavirus (HPV) testing based on cervical samples is important for use in cervical cancer screening. However, cervical sampling is invasive. Therefore, non-invasive methods for detecting HPV, such as urine samples, are needed. For HPV detection in urine samples, two real-time PCR (RQ-PCR) tests, Roche cobas 4800 test (Roche_HPV; Roche Molecular Diagnostics) and Abbott RealTime High Risk HPV test (Abbott_HPV; Abbott Laboratories) were compared to standard cervical samples. The performance of Roche_HPV and Abbott_HPV for HPV detection was evaluated at the National Cancer Center using 100 paired cervical and urine samples. The tests were also compared using urine samples stored at various temperatures and for a range of durations. The overall agreement between the Roche_HPV and Abbott_HPV tests using urine samples for any hrHPV type was substantial (86.0% with a kappa value of 0.7173), and that for HPV 16/18 was nearly perfect (99.0% with a kappa value of 0.9668). The relative sensitivities (based on cervical samples) for HPV 16/18 detection using Roche_HPV and Abbott_HPV with urine samples were 79.2% (95% CI; 57.9-92.9%) and 81.8% (95% CI; 59.7-94.8%), respectively. When the cut-off C T value for Abbott_HPV was extended to 40 for urine samples, the relative sensitivity of Abbott_HPV increased to 91.7% from 81.8% for HPV16/18 detection and to 87.0% from 68.5% for other hrHPV detection. The specificity was not affected by the change in the C T threshold. Roche_HPV and Abbott_HPV showed high concordance. However, HPV DNA detection using urine samples was inferior to HPV DNA detection using cervical samples. Interestingly, when the cut-off C T value was set to 40, Abbott_HPV using urine samples showed high sensitivity and specificity, comparable to those obtained using cervical samples. Fully automated DNA extraction and detection systems, such as Roche_HPV and Abbott_HPV, could reduce the variability in HPV detection and accelerate the standardization of HPV

Primates reached a great abundance and diversity during the Eocene, favored by warm temperatures and by the development of dense forests throughout the Northern Hemisphere. Here we describe new primate material from La Verrerie de Roches, a Middle Eocene karstic infill situated in the Jura Region (Switzerland), consisting of more than 80 dental remains. The primate assemblage from La Verrerie de Roches includes five different taxa. The best represented primate is Necrolemur aff. anadoni, similar in size and overall morphology to Necrolemur anadoni but resembling in some features the younger species Necrolemur antiquus. Microchoerines are also represented by two species of Pseudoloris, P. pyrenaicus and Pseudoloris parvulus, constituting the unique joint record of these two species known up to now. Remains of Adapiformes are limited to one isolated tooth of a large anchomomyin and another tooth belonging to the small adapine Microadapis cf. sciureus. The studied primate association allows assigning La Verrerie de Roches to the Robiacian Land Mammal Age. More specifically, this site can be confidently situated between the MP15 and MP16 reference levels, although the primate assemblage probably indicates some degree of temporal mixing. This is the first record of P. pyrenaicus and a form closely related to N. anadoni out of the Iberian Peninsula. The identification of these microchoerines in Switzerland gives further support to the connection of NE Spain and Central Europe during the Middle Eocene. Copyright © 2017 Elsevier Ltd.

Adaptation of the Randox Enzymatic Manual UV Ammonia method to be used on the Roche Cobas 6000 (c501) automated analyzer platform. The Randox ammonia reagent was evaluated for precision, linearity, accuracy and interference from hemolysis, icterus and lipemia on the Roche c501 analyzer. Comparison studies were conducted for the Randox reagent between Roche c501, Siemens Vista, Ortho Vitros 250, and Beckman DxC methods. The Randox reagent demonstrates acceptable within-run (L1=65 μmol/L, CV 3.4% L2=168 μmol/L, CV 1.9%) and between-run precision (L1=29 μmol/L, CV 7.3% L2=102 μmol/L, CV 3.0%), Analytical Measurement Range (7-940 μmol/L), and accuracy. The method interference profile is superior for the Randox method (hemolysis index up to 600, icteric index up to 60, lipemic index up to 100) as compared to the Roche method (hemolysis index up to 200, icteric index up to 10, lipemic index up to 50). Comparison was very good between the Randox reagent and two other wet chemistry platforms. The Randox Enzymatic Manual UV Ammonia reagent is an available alternative to the Roche Cobas c501 reagent. The method is more robust to endogenous interferences and less prone to instrument error flags, thus allowing the majority of clinical specimens to be reported without additional sample handling at our institution.

Life near the Roche limit - Behavior of ejecta from satellites close to planets

Dobrovolskis, A. R.; Burns, J. A.

1980-01-01

A study of the dynamics of nearby debris from impact craters was made to explain the distinctive features seen on Phobos, Deimis, and Amalthea. The planetary tides and satellite rotation were considered, and the usual pseudo-energy (Jacobi) integral was numerically calculated in the framework of a restricted body problem where satellites are modelled as triaxial ellipsoids rather than point masses. Iso-contours of this integral show that Deimos and Amalthea are entirely closed by Roche lobes, and the surfaces of their model ellipsoids lie nearly along equipotentials. Presently, the surface of Phobos overflows its Roche lobe, except for regions within a few km of the sub-Mars and anti-Mars points. The behavior of crater ejecta from the satellites of Mars were also examined by numerical integration of trajectories for particles leaving their surfaces in the equatorial plane.

Alteration in sample preparation to increase the yield of multiplex Polymerase Chain Reaction assay for diagnosis of genital ulcer disease

Full Text Available Purpose: Genital Ulcer Disease (GUD is common sexually transmitted infection (STI. Multiple studies have shown that GUDs are strongly associated with the transmission and the acquisition of HIV infection. An accurate diagnosis of common etiology of GUD namely Herpes, syphilis and Chancroid is possible using Multiplex PCR (M-PCR. However, frequent presence of Polymerase Chain Reaction inhibitors in the ulcer swab specimen limits the performance of the assay. In order to overcome this problem, alternative specimen preparation method was used. Materials and Methods: To determine the common etiology, GUD specimens obtained under an STI operations research study were tested with M-PCR after the samples were prepared using Roche Amplicor specimen preparation kit. PCR inhibiting samples were identified from that, which showed negative results. These samples were subjected to phenol-chloroform extraction and ethanol precipitation before the conduct of M-PCR on them. Results: Of the 237 GUD specimens tested, in 145 etiologies could be detected, whereas 92 samples were found negative. Further spiking with one of the target DNA, 128 of the negative samples were found to contain the inhibitors. These 126 samples were then subjected to phenol chloroform extraction and ethanol precipitation followed by M-PCR. Using this method for sample preparation, etiology could be determined in 46 (23% additional samples. This success rate of altered sample preparation method has been lower than that has reported. Conclusion: The results indicate that sample preparation using phenol chloroform extraction and ethanol precipitation, prior to M-PCR helps to eliminate the inhibitors and increase the yield of the assay. However, being a laborious procedure, it may be used for samples giving negative results after the screening by Roche Amplicor specimen preparation kit.

The aim of this study was to develop a novel method for automated quantification of cell-free hemoglobin (fHb) based on the HI (Roche Diagnostics). The novel fHb method based on the HI was correlated with fHb measured using the triple wavelength methods of both Harboe [fHb, g/L = (0.915 * HI + 2.634)/100] and Fairbanks et al. [fHb, g/L = (0.917 * HI + 2.131)/100]. fHb concentrations were estimated from the HI using the Roche Modular automated platform in self-made and commercially available quality controls, as well as samples from a proficiency testing scheme (INSTAND). The fHb using Roche automated HI results were then compared to results obtained using the traditional spectrophotometric assays for one hundred plasma samples with varying degrees of hemolysis, lipemia and/or bilirubinemia. The novel method using automated HI quantification on the Roche Modular clinical chemistry platform correlated well with results using the classical methods in the 100 patient samples (Harboe: r = 0.9284; Fairbanks et al.: r = 0.9689) and recovery was good for self-made controls. However, commercially available quality controls showed poor recovery due to an unidentified matrix problem. The novel method produced reliable determination of fHb in samples without interferences. However, poor recovery using commercially available fHb quality control samples currently greatly limits its usefulness. © 2013.

Clinical laboratories are expected to reliably identify human papilloma virus (HPV) associated oropharyngeal squamous cell carcinoma (OPSCC) for prognostic and potential therapeutic applications. In addition to surrogate p16 immunohistochemistry (IHC) testing, DNA-based HPV-specific testing strategies are widely utilized. Recognizing the efficiency of the Roche Cobas 4800 platform for testing gynecological cytology specimens for high-risk HPV, we elected to evaluate the potential utility of this platform for testing formalin-fixed paraffin-embedded (FFPE) OPSCC tissue. Using the Roche Linear Array assay for comparison, we tested twenty-eight samples (16 primary OPSCC, 2 lymph node metastases from primary OPSCC, 1 oral tongue carcinoma, 3 benign squamous papillomas, and 3 non-oropharyngeal carcinoma tissues). Excluding two invalid results, the Roche Cobas 4800 testing resulted in excellent inter-assay concordance (25/26, 96.2%) and 100% concordance for HPV-16/HPV-18 positive samples. This data suggests that the Roche Cobas 4800 platform may be a cost-effective method for testing OPSCC FFPE tissues in a clinical molecular pathology laboratory setting.

Strategy for the maximization of clinically relevant information from hepatitis C virus, RT-PCR quantification.

LENUS (Irish Health Repository)

Levis, J

2012-02-03

BACKGROUND: The increasing clinical application of viral load assays for monitoring viral infections has been an incentive for the development of standardized tests for the hepatitis C virus. OBJECTIVE: To develop a simple model for the prediction of baseline viral load in individuals infected with the hepatitis C virus. METHODOLOGY: Viral load quantification of each patient\\'s first sample was assessed by RT-PCR-ELISA using the Roche MONITOR assay in triplicate. Genotype of the infecting virus was identified by reverse line probe hybridization, using amplicons resulting from the qualitative HCV Roche AMPLICOR assay. RESULTS: Retrospective evaluation of first quantitative values suggested that 82.4% (n=168\\/204) of individuals had a viral load between 4.3 and 6.7 log(10) viral copies per ml. A few patients (3.4%; n=7\\/204) have a serum viremia less than the lower limit of the linear range of the RT-PCR assay. Subsequent, prospective evaluation of hepatitis C viral load of all new patients using a model based on the dynamic range of viral load in the retrospective group correctly predicted the dynamic range in 75.9% (n=33\\/54). CONCLUSION: The dynamic range of hepatitis C viremia extends beyond the linear range of the Roche MONITOR assay. Accurate determination of serum viremia is substantially improved by dilution of specimens prior to quantification.

Use of Roche coordinates in the problems of small oscillations of tidally-distorted stellar models. II

Kopal's method of Roche coordinates used by the authors in an earlier paper (Mohan and Singh, 1978) to study the problems of small oscillations of tidally-distorted stars has been extended further to take into account the effect of second-order terms in tidal distortion. The results show that the effect of including terms of second order of smallness in tidal distortion in the metric coefficients of the Roche coordinates of tidally distroted stars is quite significant, especially in case of stars with extended envelopes and (or) larger values of the companion star producing tidal distortion. Some of the models which were earlier found stable against small perturbations now become dynamically unstable with the inclusion of the terms of second order of smallness in tidal effects. (Auth.)

Polyphony and counterpoint: Mechanisms of seduction in the diaries of Helen Hessel and Henri Pierre Roché

Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché. Henri Pierre Roché (1879–1959, outeur van Jules et Jim, word beskryf as ‘n sosiale koppelaar, ‘n model-liefhebber van alles en nog wat, ‘n versamelaar van vroue en kuns en een van die mees produktiewe dagboekskrywers en aktiewe minnaars in die opgetekende geskiedenis. Roché het ‘n reeks sketse oor Don Juan gepubliseer en was geboei deur die figuur van die verleier. In sy twintigs beplan hy om sy lewe te wy aan die skepping van ‘n œuvre wat die morele, intellektuele, sosiale en seksuele verhoudings tussen mans en vrouens sou ondersoek. Ter bereiking van hierdie doel, rig hy sy lewe in as laboratorium waarin werklike ondervindinge dien as hoofbron van inligting. Sy dagboek strek oor sestig jaar en is ryk aan verhale van verleiding. Desnieteenstaande bly die mees intense en boeiende intrige van verleiding en verraad steeds sy verhouding met Helen Hessel. Aan die begin van hulle verhouding, stel Roché voor dat sy ook ‘n dagboek hou van hulle hartstogtelike liefde. Helen Hessel se dagboek, geskryf in Frans, Duits en Engels, reflekteer die drama van verleiding en funksioneer op verskillende vlakke: realisties, visionêr, ten volle geabsorbeer in haar eie gedagtes en emosies en tóg krities jeens haarself en ander. ‘n Vergelyking van die twee dagboeke skep ‘n fassinerende, digte tekstuur wat die binnewerkings blootlê van verleiding in aksie. Die kontrapunt geskep deur hierdie twee interafhanklike stemme word nóg meer kompleks namate ‘n mens bewus word van die intertekstuele verwysings wat bydra tot die ontluikende polifonie van geskrewe liefde en lewe.

Numerical Simulations of Gaseous Disks Generated from Collisional Cascades at the Roche Limits of White Dwarf Stars

We consider the long-term evolution of gaseous disks fed by the vaporization of small particles produced in a collisional cascade inside the Roche limit of a 0.6 {M}⊙ white dwarf. Adding solids with radius {r}0 at a constant rate {\\dot{M}}0 into a narrow annulus leads to two distinct types of evolution. When {\\dot{M}}0≳ {\\dot{M}}0,{crit}≈ 3× {10}4 {({r}0/1{km})}3.92 {{g}} {{{s}}}-1, the cascade generates a fairly steady accretion disk where the mass transfer rate of gas onto the white dwarf is roughly {\\dot{M}}0 and the mass in gas is {M}g≈ 2.3× {10}22 ({\\dot{M}}0/{10}10 {{g}} {{{s}}}-1) (1500 {{K}}/{T}0) ({10}-3/α ) g, where T 0 is the temperature of the gas near the Roche limit and α is the dimensionless viscosity parameter. If {\\dot{M}}0≲ {\\dot{M}}0,{crit}, the system alternates between high states with large mass transfer rates and low states with negligible accretion. Although either mode of evolution adds significant amounts of metals to the white dwarf photosphere, none of our calculations yield a vertically thin ensemble of solids inside the Roche limit. X-ray observations can place limits on the mass transfer rate and test this model for metallic line white dwarfs.

Chemical analysis of body fluids is commonly requested by physicians. Because most commercial FDA-cleared clinical laboratory assays are not validated by diagnostic manufacturers for "non-serum" and "non-plasma" specimens, laboratories may need to complete additional validation studies to comply with regulatory requirements regarding body fluid testing. The objective of this report is to perform recovery studies to evaluate potential body fluid matrix interferences for commonly requested chemistry analytes. Using an IRB-approved protocol, previously collected clinical body fluid specimens (biliary/hepatic, cerebrospinal, dialysate, drain, pancreatic, pericardial, peritoneal, pleural, synovial, and vitreous) were de-identified and frozen (-20°C) until experiments were performed. Recovery studies (spiking with high concentration serum, control, and/or calibrator) were conducted using 10% spiking solution by volume; n=5 specimens per analyte/body fluid investigated. Specimens were tested on a Roche cobas 8000 system (c502, c702, e602, and ISE modules). In all 80 analyte/body fluid combinations investigated (including amylase, total bilirubin, urea nitrogen, carbohydrate antigen 19-9, carcinoembryonic antigen, cholesterol, chloride, creatinine, glucose, potassium, lactate dehydrogenase, lipase, rheumatoid factor, sodium, total protein, triglycerides, and uric acid), the average percent recovery was within predefined acceptable limits (less than ±10% from the calculated ideal recovery). The present study provides evidence against the presence of any systematic matrix interference in the analyte/body fluid combinations investigated on the Roche cobas 8000 system. Such findings support the utility of ongoing body fluid validation initiatives conducted to maintain compliance with regulatory requirements.

Both Roche and Abbott have released new glucose meter strips. They supply the entire Australian hospital market. The present study compared the performance of the new strips utilizing various specimen types (capillary, venous lithium heparin whole blood, venous lithium heparin plasma and serum) and evaluated how well they comply with the International Standards Organization (ISO) 15197 criteria. The study included imprecision, patient comparison and interference studies. Participants with and without diabetes were recruited to evaluate the performance of various specimen types against the Beckman DxC800 glucose method. The strips were tested for different interferences: galactose, maltose, lactose, Icodextrin, Intragam, paracetamol, sodium, ascorbic acid, variable strip storage temperature, haematocrit, haemolysis and lipaemia. The imprecision of the two strips was approximately 5% or less, except for the Abbott strip at very low values (1.4 mmol/L), approximately 7%. In total, 78% and 84%, respectively, of the results from the finger prick capillary specimens with the Roche (Accu-Chek Performa meter) and Abbott (Optium Xceed meter) strips, not 95% or greater as recommended by the ISO guideline, were within the recommended limits compared with reference plasma estimation on laboratory analysers. Galactose, ascorbic acid, haematocrit and sodium on the Roche and ascorbic acid and haematocrit on the Abbott strip continue to interfere to a variable degree with the glucose measurement. Analytically small differences exist between the glucose meter strips. The most significant analytical difference with the strips was at low glucose levels when compared with laboratory analyses and this may be of clinical importance. The impact of some of the interferences is variable between the two strips. Individuals, health-care professionals and health-care institutions should consider these data when selecting glucose meters for the management of people with diabetes mellitus.

The alteration of rocks intended for use as the foundations of large-scale civil-engineering projects, for building construction and for rock piling has been studied and numerous tests carried out; some of these tests have been standardized in varying degrees. The conventional method of autoradiography has been used to develop one of the processes for estimating alteration due, in particular, to thermal shocks. By using {sup 35}S and {sup 32}P, the authors were able to follow the progressive alteration of different rocks in the form of microfissurations. This process is considerably more accurate than that based solely on utilization of the characteristics of rocks in normal or polarized light. In addition, it permits absolute comparison of the initial microfissuration conditions of the sample and the microfissuration found after an increasing number of thermal shock cycles. The results of the process are given in the paper. (author) [French] L'alterabilite des roches destinees, soit a des fondations de grands travaux de genie civil, soit a la construction d'immeubles, soit enfin a l'etablissement d'enrochements, a fait l'objet de nombreux essais dont certains ont ete normalises, ou tout au moins ont subi un debut de normalisation. Un des procedes de determination du processus d'alteration du notamment aux chocs thermiques a ete mis au point a partir de la methode classique d'autoradiographie. L'utilisation de {sup 35}S et de {sup 32}P a permis de suivre la progression de l'alteration par microfissuration dans des roches diverses. Ce procede est notablement plus precis que celui qui est fonde sur la seule utilisation des caracteristiques des roches en lumiere naturelle ou polarisee. De plus, il permet la comparaison en valeur absolue de l'etat de microfissuration initial de l'echantillon avec la microfissuration obtenue apres un nombre croissant de cycles de chocs thermiques. Les resultats obtenus grace a ce procede sont donnes dans le memoire. (author)

Roche and IAEA announce joint initiative to train healthcare workers for Africa's fight against cancer. EDUCARE partnership to launch IAEA's VUCCnet training networks

International Nuclear Information System (INIS)

2010-01-01

Full text: Roche and the International Atomic Energy Agency (IAEA) announced today the launch of the EDUCARE (EDUcation for Cancer in African REgions) project to provide concerted support to help combat the growing cancer epidemic in sub-Saharan Africa. The EDUCARE project is to be piloted in Ghana, Tanzania, Uganda and Zambia, and is linked with the IAEA's wider initiative to build regional training networks in cancer control and a Virtual University for Cancer Control (VUCCnet) in Africa. A core component for the successful fight against cancer in any country is the education and training of health care providers. The VUCCnet will allow for training to be provided in an integrated and sustainable way in Africa by taking advantage of low-cost online learning tools. The IAEA is working in collaboration with the World Health Organization (WHO) and other international partners to develop the VUCCnet across Africa. The EDCUARE project will facilitate a first-of-its-kind exchange of knowledge and skills, both at the healthcare provider and country-wide level. Training will be provided by an on-line training resource centre, known as the Virtual University for Cancer Control (VUCC), the first such platform for health workers across the continent. Maturin Tchoumi, General Manager Roche South Africa said: 'As a leader in oncology, Roche believes that its strengths, expertise and resources can be used to improve the quality of oncology training and education in the poorest countries in the world. There is a real lack of basic education in oncology in Africa. By contributing our skills and competencies on the ground, Roche can make a real and sustainable improvement.' This new public-private partnership reflects a shared concern over the increasing cancer burden in sub-Saharan Africa, a region of the world where cancer rates are growing rapidly. Cancer now accounts for 12.5% of all deaths worldwide, more than HIV/AIDS, TB and malaria combined. By 2020, there are expected to

The Aptima HCV Quant Dx assay (Aptima assay) is a fully automated quantitative assay on the Panther® system. This assay is intended for confirmation of diagnosis and monitoring of HCV RNA in plasma and serum specimens. The purpose of the testing described in this paper was to evaluate the performance of the Aptima assay. The analytical sensitivity, analytical specificity, precision, and linearity of the Aptima assay were assessed. The performance of the Aptima assay was compared to two commercially available HCV assays; the Abbott RealTime HCV assay (Abbott assay, Abbott Labs Illinois, USA) and the Roche COBAS Ampliprep/COBAS Taqman HCV Quantitative Test v2.0 (Roche Assay, Roche Molecular Systems, Pleasanton CA, USA). The 95% Lower Limit of Detection (LoD) of the assay was determined from dilutions of the 2nd HCV WHO International Standard (NIBSC 96/798 genotype 1) and HCV positive clinical specimens in HCV negative human plasma and serum. Probit analysis was performed to generate the 95% predicted detection limits. The Lower Limit of Quantitation (LLoQ) was established for each genotype by diluting clinical specimens and the 2nd HCV WHO International Standard (NIBSC 96/798 genotype 1) in HCV negative human plasma and serum. Specificity was determined using 200 fresh and 536 frozen HCV RNA negative clinical specimens including 370 plasma specimens and 366 serum specimens. Linearity for genotypes 1 to 6 was established by diluting armored RNA or HCV positive clinical specimens in HCV negative serum or plasma from 8.08 log IU/mL to below 1 log IU/mL. Precision was tested using a 10 member panel made by diluting HCV positive clinical specimens or spiking armored RNA into HCV negative plasma and serum. A method comparison was conducted against the Abbott assay using 1058 clinical specimens and against the Roche assay using 608 clinical specimens from HCV infected patients. In addition, agreement between the Roche assay and the Aptima assay using specimens with low

The pH may impact the concentration of certain urinary parameters, making urine pre-treatment questionable. 1) Determining the impact of pH in vitro on the urinary concentration of chemistry parameters assayed on Roche Modular analyzers. 2) Evaluating whether concentrations depended on pH in non-pretreated urines from patients. 1) The optimal urinary pH values for each measurement were: 6.3 ± 0.8 (amylase), 6.5 (uric acid). Urinary creatinine, sodium and urea concentrations were not pH-dependent. 2) In urines from patients, the pH was negatively associated with the concentration of some urinary parameters. However, concentrations of all the parameters were strongly and positively correlated with urinary creatinine, and relationships with pH were no longer evidenced after creatinine-normalization. The need for urine pH adjustment does not seem necessary when considering renal function. However, from an analytical and accreditation standpoint, the relationship between urine pH and several parameters justifies its measurement.

High-risk human papilloma virus (HPV) seems to play a role in the pathogenesis of cervical squamous neoplasia and adenocarcinomas of the mucinous and endometrioid cell types. Cervical serous, clear cell, and small cell carcinomas differ from the conventional endocervical adenocarcinoma in their clinical characteristics. The data on the role of HPV in their pathogenesis are limited. In this study, we examined the presence of high-risk HPV-DNA in rare types of cervical carcinoma using polymerase chain reaction-based test. In-house cervical serous, clear cell, and small cell carcinoma cases accessioned between 2000 and 2008 were tested for HPV by polymerase chain reaction amplification of DNA extracted from deparaffinized sections using Roche AMPLICOR HPV Amplification Detection and Control Kits. The kit detects all 13 high-risk HPV-DNA genotypes. The positive cut-off point for AMPLICOR HPV Test was A450 = 0.2. We identified 4 serous, 3 clear cell, 1 mixed clear cell and serous, and 5 small cell carcinomas. High-risk HPV-DNA tested positive in 3 out of 4 serous carcinomas, 2 out of 3 cervical clear cell carcinomas, and all 5 cases of small cell carcinoma and the mixed cell type. Our report documents HPV status in a series of archival unusual types of adenocarcinoma of the uterine cervix. It suggests a robust association between high-risk HPV and these rare subtypes. Despite their unique clinical setting and morphologic appearance, the majority of these tumors likely share a common HPV-mediated carcinogenic pathway. Our observation is particularly significant in cervical cancer prevention as we enter the HPV vaccination era.

After observing a high incidence of low positive hepatitis C virus (HCV) antibody screens by the Ortho-Clinical Vitros ECi test (Orthoclinical Diagnostics, Raritan, NJ), we compared results against those obtained using another chemiluminescent analyzer, as well as two U.S. Food and Drug Administration (FDA)-approved confirmatory methodologies. To ascertain the true anti-HCV status of samples deemed low-positive by the Ortho-Clinical Vitros ECi test, we tested samples using the ADVIA Centaur HCV screen test (Siemens Medical Solutions Diagnostics), the Chiron recombinant immunoblot assay (RIBA) test (Chiron Corp., Emeryville, CA), and the Roche COBAS Amplicor HCV qualitative test (Roche Diagnostics, Indianapolis, IN) in a series of studies. Of 94 specimens positive by Vitros ECi, 19% were observed to be negative by Centaur. A separate study of 91 samples with signal-to-cutoff (s/co) values less than 8.0 showed that all but one was negative for HCV ribonucleic acid (RNA). In comparison with RIBA, 100% (77) samples positive by the Vitros ECi test with s/co values less than 12.0 were negative or indeterminate by RIBA. A final study comparing all four methods side-by-side showed 63% disagreement by Centaur for Vitros ECi low-positive samples, 75% disagreement by RIBA, and 97% disagreement by polymerase chain reaction (PCR). In conclusion, the Ortho-Clinical Vitros ECi Anti-HCV test yields a high rate of false-positive results in the low s/co range in our patient population. (c) 2007 Wiley-Liss, Inc.

Next-generation sequencing (NGS) is commonly used in metagenomic studies of complex microbial communities but whether or not different NGS platforms recover the same diversity from a sample and their assembled sequences are of comparable quality remain unclear. We compared the two most frequently used platforms, the Roche 454 FLX Titanium and the Illumina Genome Analyzer (GA) II, on the same DNA sample obtained from a complex freshwater planktonic community. Despite the substantial differences in read length and sequencing protocols, the platforms provided a comparable view of the community sampled. For instance, derived assemblies overlapped in ~90% of their total sequences and in situ abundances of genes and genotypes (estimated based on sequence coverage) correlated highly between the two platforms (R(2)>0.9). Evaluation of base-call error, frameshift frequency, and contig length suggested that Illumina offered equivalent, if not better, assemblies than Roche 454. The results from metagenomic samples were further validated against DNA samples of eighteen isolate genomes, which showed a range of genome sizes and G+C% content. We also provide quantitative estimates of the errors in gene and contig sequences assembled from datasets characterized by different levels of complexity and G+C% content. For instance, we noted that homopolymer-associated, single-base errors affected ~1% of the protein sequences recovered in Illumina contigs of 10× coverage and 50% G+C; this frequency increased to ~3% when non-homopolymer errors were also considered. Collectively, our results should serve as a useful practical guide for choosing proper sampling strategies and data possessing protocols for future metagenomic studies.

Validation of the LT-SYS quantitative in vitro copper assay on a Roche Cobas 8000 c502 analyzer and comparison with a BIOMED assay on a Roche Cobas Mira analyzer. Imprecision and bias were quantified at different concentration levels (serum and plasma) over a 20-day period. Linearity was assessed covering a range from 4.08 µmol/L to 33.8 µmol/L. Limit of blank (LoB) and limit of detection (LoD) were established based on a total of 120 blank and low-level samples. The method comparison was based on 58 plasma samples. Within-run imprecision ranged from 0.7% to 1.2% and within-laboratory imprecision from 1.4% to 3.3%. Relative bias for the 2 serum pools with known target values was less than 2.5%. The assay did not deviate from linearity over the tested measuring range. LoB and LoD were 0.12 µmol/L and 0.23 µmol/L, respectively. The method comparison revealed an average deviation of 11.5% (2.016 µmol/L), and the linear regression fit was y = 1.464 + 0.795x. The LT-SYS copper assay characterized in this study showed a fully acceptable performance with good degrees of imprecision and bias, no deviation from linearity in the relevant measuring rangem, and very low LoB and LoD. © American Society for Clinical Pathology, 2016.

2015-12-01

Changes in the composition of microbial communities that colonize skin have been linked to several diseases including psoriasis. Nevertheless, the intra-individual dynamics and how these communities respond to balneotherapy remain poorly understood. This open label study was conducted between July and September 2012. Microbial communities of patients with psoriasis vulgaris were characterized prior and post a 3-week selenium-rich water balneotherapy treatment at the thermal care center La Roche-Posay (La Roche-Posay, France). Balneotherapy consisted of high-pressure filiform showers, baths, facial, and body spray treatments as well as La Roche-Posay thermal spring water (LRP-TSW) consumption. Swabs were taken from affected and proximal unaffected skin and the 16S rRNA bacterial gene was used to analyze the composition of bacterial communities. Using the same 16S rRNA gene tool, we tried to describe the LRP-TSW bacterial landscape. This study included 54 patients diagnosed with moderate to severe forms of psoriasis vulgaris. After eliminating individuals lacking paired samples from both visits, 29 individuals were analyzed for their microbiome profile. Shannon Diversity Index and global bacterial landscape indicate similar microbial communities on both unaffected and adjacent affected skin. PASI values decreased post-balneotherapy implying improvement of disease severity. No significant change in the Shannon Diversity Index was noticed at the end of the third week. The average taxonomic composition of skin microbial communities associated with unaffected and affected skin of psoriatic patients post-balneotherapy shows that treatment with LRP-TSW significantly increased the level of Xanthomonas genus and, to a lesser extent, Corynebacterium genus. The Xanthomonas genus belongs to the main Xanthomonadaceae family found in LRP-TSW and also on healthy skin. In psoriatic patients, a poor bacterial biodiversity was noticed and the bacterial communities were similar on

Full Text Available Next-generation sequencing (NGS is commonly used in metagenomic studies of complex microbial communities but whether or not different NGS platforms recover the same diversity from a sample and their assembled sequences are of comparable quality remain unclear. We compared the two most frequently used platforms, the Roche 454 FLX Titanium and the Illumina Genome Analyzer (GA II, on the same DNA sample obtained from a complex freshwater planktonic community. Despite the substantial differences in read length and sequencing protocols, the platforms provided a comparable view of the community sampled. For instance, derived assemblies overlapped in ~90% of their total sequences and in situ abundances of genes and genotypes (estimated based on sequence coverage correlated highly between the two platforms (R(2>0.9. Evaluation of base-call error, frameshift frequency, and contig length suggested that Illumina offered equivalent, if not better, assemblies than Roche 454. The results from metagenomic samples were further validated against DNA samples of eighteen isolate genomes, which showed a range of genome sizes and G+C% content. We also provide quantitative estimates of the errors in gene and contig sequences assembled from datasets characterized by different levels of complexity and G+C% content. For instance, we noted that homopolymer-associated, single-base errors affected ~1% of the protein sequences recovered in Illumina contigs of 10× coverage and 50% G+C; this frequency increased to ~3% when non-homopolymer errors were also considered. Collectively, our results should serve as a useful practical guide for choosing proper sampling strategies and data possessing protocols for future metagenomic studies.

We study the evolution of close binary systems formed by a normal (solar composition), intermediate-mass-donor star together with a neutron star. We consider models including irradiation feedback and evaporation. These nonstandard ingredients deeply modify the mass-transfer stages of these binaries. While models that neglect irradiation feedback undergo continuous, long-standing mass-transfer episodes, models including these effects suffer a number of cycles of mass transfer and detachment. During mass transfer, the systems should reveal themselves as low-mass X-ray binaries (LMXBs), whereas when they are detached they behave as binary radio pulsars. We show that at these stages irradiated models are in a Roche lobe overflow (RLOF) state or in a quasi-RLOF state. Quasi-RLOF stars have radii slightly smaller than their Roche lobes. Remarkably, these conditions are attained for an orbital period as well as donor mass values in the range corresponding to a family of binary radio pulsars known as ''redbacks''. Thus, redback companions should be quasi-RLOF stars. We show that the characteristics of the redback system PSR J1723-2837 are accounted for by these models. In each mass-transfer cycle these systems should switch from LMXB to binary radio pulsar states with a timescale of approximately one million years. However, there is recent and fast growing evidence of systems switching on far shorter, human timescales. This should be related to instabilities in the accretion disk surrounding the neutron star and/or radio ejection, still to be included in the model having the quasi-RLOF state as a general condition.

Pre-analytical sample processing is often overlooked as a potential cause of inaccurate assay results. Here we demonstrate how plasma, extracted from standard EDTA-containing blood collection tubes, may contain traces of blood cells consequently resulting in a false low-level HIV-1 viral load when using Roche Cobas HIV-1 assays. The presence of human DNA in Roche Cobas 4800 RNA extracts and in RNA extracts from the Abbott HIV-1 RealTime assay was assessed by quantifying the human albumin gene by means of quantitative PCR. RNA was extracted from plasma samples before and after an additional centrifugation and tested for viral load and DNA contamination. The relation between total DNA content and viral load was defined. Elevated concentrations of genomic DNA were detected in 28 out of 100 Cobas 4800 extracts and were significantly more frequent in samples processed outside of the AIDS Reference Laboratory. An association between genomic DNA presence and spurious low-level viraemia results was demonstrated. Supplementary centrifugation of plasma before RNA extraction eliminated the contamination and the false viraemia. Plasma isolated from standard EDTA-containing blood collection tubes may contain traces of HIV DNA leading to false viral load results above the clinical cutoff. Supplementary centrifugation of plasma before viral load analysis may eliminate the occurrence of this spurious low-level viraemia.

10Be dating of the Main Terrace level in the Amblève valley (Ardennes, Belgium): new age constraint on the archaeological and palaeontological filling of the Belle-Roche palaeokarst

It is still disputed whether very old archaeological and palaeontological remains found in the Belle-Roche palaeocave (eastern Belgium) pertain to the Early (˜1 Ma) or Middle (˜0.5 Ma) Pleistocene. Here, in situ-produced cosmogenic 10Be concentrations from a depth profile in nearby sediments of the Belle-Roche terrace (Amblève Main Terrace level) are used as an indirect solution of this chronological issue. The distribution of 10Be concentrations in the upper 3 m of this profile displays the theoretically expected exponential decrease with depth. Assuming a single exposure episode, we obtain a best fit age of 222.5±31 ka for the time of terrace abandonment. However, below 3 m, the 10Be concentrations show a marked progressive increase with depth. This distinctive cosmogenic signal is interpreted as the result of slow aggradation of the fluvial deposits over a lengthy interval. Modelling of the whole profile thus suggests that the onset of the terrace formation occurred at around 550 ka, with a sediment accumulation rate of ˜20 mm/ka. Based on two slightly different reconstructions of the geomorphic evolution of the area and a discussion of the temporal link between the cave and Main Terrace levels, we conclude that the fossil-bearing layers in the palaeokarst pertain most probably to MIS 14-13 (or possibly MIS 12-11) and the artifact-bearing layer to MIS 13 (or possibly MIS 11). This age estimate for the large mammal association identified in the Belle-Roche palaeokarst and the attribution to MIS 14-13 of a similar fauna found in the lowermost fossiliferous layers of the Caune de l'Arago (Tautavel) are in mutual support. Our results therefore confirm the status of the Belle-Roche site as a reference site for the Cromerian mammal association and the Early Palaeolithic industry in NW Europe.

The presence of HIV-1 non-B subtypes is increasing worldwide. This poses challenges to commercial diagnostic and viral load (RNA) monitoring tests that are predominantly based on HIV-1 subtype B strains. Based on phylogenetic analysis of the gag, pol, and env gene regions, we describe the first HIV-1 H/J recombinant in Canada that presented divergent viral load values. DNA sequence analysis of the gag gene region further revealed that genetic diversity between this H/J recombinant and the primers and probes used in the bio-Merieux Nuclisens HIV-1 QT (Nuclisens) and Roche Amplicor Monitor HIV-1, v1.5 (Monitor) viral RNA assays can erroneously lead to undetectable viral load values. This observation appears to be more problematic in the Nuclisens assay. In light of increasing genetic diversity in HIV worldwide we recommend that DNA sequencing of HIV, especially in the gag gene region targeted by primers and probes used in molecular diagnostic and viral load tests, be incorporated into clinical monitoring practices.

Background Biotin interference is a significant problem to which at-risk laboratories must now be attuned. We sought to systematically characterize the nature of this interference in Roche immunoassays. Methods Known concentrations of biotin were titrated into serum samples and the effects on competitive and sandwich immunoassays were analysed. The maximum and minimum concentrations examined reflect those likely to be achieved in individuals on 5 to 10 mg supplements at the lower end, and 100 to 300 mg biotin at the high end. Results A high variability in biotin tolerance was observed. Some assays, such as troponin T, TSH and antithyroid antibodies, were extremely sensitive to the lower concentrations of biotin (15.6 and 31.3 ng/mL), whereas the majority of assays were relatively resistant. At concentrations ≥500 ng/mL, all assays showed significant interference from biotin but, again, the magnitude of the interference was variable. The more sensitive assays showed profound analytical bias at biotin concentrations that occur with high-dose therapy. Conclusion Our data demonstrate high variability in biotin tolerance across Roche immunoassays. The shape of the dose-response curves provides more detailed information than the single manufacturer-quoted figure for biotin tolerance. Accordingly, these data may be used by laboratories for more accurate risk assessment in predicting the effects of biotin. Our data may also be extrapolated to guide timing of blood tests in patients on high-dose biotin therapy: it demonstrates the number of half-lives required to withhold biotin in order to decrease its concentration to below a given assay tolerance.

The aim of our study was to perform verification of serum indices on three clinical chemistry platforms. This study was done on three analyzers: Abbott Architect c8000, Beckman Coulter AU5800 (BC) and Roche Cobas 6000 c501. The following analytical specifications were verified: precision (two patient samples), accuracy (sample with the highest concentration of interferent was serially diluted and measured values compared to theoretical values), comparability (120 patients samples) and cross reactivity (samples with increasing concentrations of interferent were divided in two aliquots and remaining interferents were added in each aliquot. Measurements were done before and after adding interferents). Best results for precision were obtained for the H index (0.72%-2.08%). Accuracy for the H index was acceptable for Cobas and BC, while on Architect, deviations in the high concentration range were observed (y=0.02 [0.01-0.07]+1.07 [1.06-1.08]x). All three analyzers showed acceptable results in evaluating accuracy of L index and unacceptable results for I index. The H index was comparable between BC and both, Architect (Cohen's κ [95% CI]=0.795 [0.692-0.898]) and Roche (Cohen's κ [95% CI]=0.825 [0.729-0.922]), while Roche and Architect were not comparable. The I index was not comparable between all analyzer combinations, while the L index was only comparable between Abbott and BC. Cross reactivity analysis mostly showed that serum indices measurement is affected when a combination of interferences is present. There is heterogeneity between analyzers in the hemolysis, icteria, lipemia (HIL) quality performance. Verification of serum indices in routine work is necessary to establish analytical specifications.

Numerical Simulations of Collisional Cascades at the Roche Limits of White Dwarf Stars

Science.gov (United States)

Kenyon, Scott J.; Bromley, Benjamin C.

2017-08-01

We consider the long-term collisional and dynamical evolution of solid material orbiting in a narrow annulus near the Roche limit of a white dwarf. With orbital velocities of 300 {km} {{{s}}}-1, systems of solids with initial eccentricity e≳ {10}-3 generate a collisional cascade where objects with radii r ≲ 100{--}300 {km} are ground to dust. This process converts 1-100 km asteroids into 1 μm particles in 102-106 yr. Throughout this evolution, the swarm maintains an initially large vertical scale height H. Adding solids at a rate \\dot{M} enables the system to find an equilibrium where the mass in solids is roughly constant. This equilibrium depends on \\dot{M} and {r}0, the radius of the largest solid added to the swarm. When {r}0 ≲ 10 km, this equilibrium is stable. For larger {r}0, the mass oscillates between high and low states; the fraction of time spent in high states ranges from 100% for large \\dot{M} to much less than 1% for small \\dot{M}. During high states, the stellar luminosity reprocessed by the solids is comparable to the excess infrared emission observed in many metallic line white dwarfs.

The distribution and stability of human immunodeficiency virus type 1 (HIV-1) in breast milk (BM) components remain largely unknown. Inhibitory effects, if any, of BM on HIV RNA and DNA PCR amplification are poorly understood. We have addressed these issues by using virus-spiked BM samples from HIV-negative women. BM samples from HIV-negative women were spiked with HIV-1 virions or cells containing a single integrated copy of HIV DNA (8E5/LAV). After incubation under different experimental conditions, viral RNA was detected by the Roche Amplicor UltraSensitive assay in whole-milk, skim milk, and lipid fractions. We found excellent correlation between HIV-1 input copy and recovery in whole milk (r = 0.965, P milk (r = 0.972, P 0.982). The effects of incubation duration and temperature and repeated freeze-thaw cycles on HIV RNA recovery were analyzed. HIV RNA levels were remarkably stable in whole milk after three freeze-thaw cycles and for up to 30 h at room temperature. Our findings improve the understanding of the dynamics of HIV detection in BM and the conditions for BM sample collection, storage, and processing.

Persistence of hepatitis C virus in a white population: associations with human leukocyte antigen class 1.

2012-02-03

The aim of this study was to define novel associations between human leukocyte antigen (HLA) class 1 alleles and persistence or clearance of the hepatitis C virus (HCV) in a white population. All individuals in the study were seropositive for anti-HCV antibodies. Viral status was determined by the Roche HCV Amplicor test. HLA-A, -B, -C allelic group profile was molecularly defined by reverse line probe hybridization. The strongest individual allelic group associations with persistent HCV infection were HLA A*11 (p = 0.044) and Cw*04 (p = 0.006). However, only the HLA C*04 association survived correction for multiple comparisons. Further analysis of alleles in linkage with HLA Cw*04 revealed that the haplotype HLA A*11, Cw*04 was present in 11 individuals, 10 of whom were viremic (p = 0.05). No gene dosage effect was observed. No association between HLA class 1 allelic groups and aviremia and virus load was evident in this white population. HLA B*44 is associated with low virus load in human immunodeficiency virus disease, but this association was not evident in this HCV-infected population. Novel HLA class 1 alleles associated with persistence of HCV have been identified.

To evaluate the performance of the Hologic Gen-Probe (San Diego, CA) PANTHER system. The performance of PANTHER was compared with the Hologic Gen-Probe TIGRIS and/or Roche (Indianapolis, IN) COBAS AMPLICOR systems through testing of patient specimens and the spiked-urine matrix. After discrepant resolution, PANTHER demonstrated a 99.3% (95% confidence interval [CI], 96.0%-99.9%) positive and 100% (98.5%-100.0%) negative agreement for Chlamydia trachomatis (CT) and 100% (96.6%-100.0%) positive and 100% (98.6%-100.0%) negative agreement for Neisseria gonorrhoeae (NG) for all male, female, unsexed, and NG-spiked female urine specimens combined. For other specimen types collectively, the PANTHER demonstrated 100% (95% CI, 90.6%-100.0%) positive and 100% (88.3%-100.0%) negative agreement for CT and 90.9% (62.8%-98.4%) positive and 100% (93.5%-100.0%) negative agreement for NG. Analytical sensitivity of the PANTHER in urine matrix was similar to the TIGRIS system. The PANTHER system provides an excellent new addition to options for detecting CT and NG, is appropriate for testing urine samples, and will facilitate high-throughput testing in the clinical laboratory.

We carried out a prospective study comparing the performance of human papillomavirus (HPV) E6/E7 mRNA (PreTect HPV-Proofer; NorChip, Klokkarstua, Norway) and DNA (Amplicor HPV test; Roche Diagnostics, Basel, Switzerland) triage testing of women 6 to 12 months after atypical-squamous-cells-of-undetermined-significance (ASCUS) or low-grade-squamous-intraepithelial-lesion (LSIL) cytology in organized screening to predict high-grade cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) between screening rounds. Between January 2005 and April 2008, 692 study women with screening-detected ASCUS/LSIL cytology 6 to 12 months earlier returned for HPV mRNA and DNA testing and repeat cytology. The median follow-up time was 3 years, using existing health care facilities. Follow-up test results were available for 625 women. Of the 145 CIN2+ cases detected during the study period, 95 (65.5%) were HPV mRNA positive 6 to 12 months after screening-detected ASCUS/LSIL, 44 (30.4%) were HPV mRNA negative, and 6 (4.1%) were invalid. The corresponding HPV DNA results were 139 (95.9%), 5 (3.4%), and 1 (0.7%), respectively. The cumulative incidences of CIN2+ 3 years after a negative HPV mRNA and DNA test were 10.3% (95% confidence interval [CI], 7.2 to 13.3%) and 1.8% (95% CI, 0.0 to 3.6%), respectively. The cumulative incidences of CIN2+ 3 years after positive HPV mRNA and DNA tests were 52.8% (95% CI, 40.1 to 60.1%) and 41.3% (95% CI, 35.5 to 46.6%), respectively. In conclusion, both positive HPV mRNA and DNA test results have a high enough long-term prediction of CIN2+ risk to consider referral to colposcopy as good practice when performed in delayed triage of women with ASCUS/LSIL cytology. In addition, the low CIN2+ risk among women with a negative Amplicor HPV test in our study confirms its safe use in a clinical setting. PMID:22518869

Full Text Available Objectives: Thyroglobulin (Tg measurements are used to monitor for residual thyroid tissue in patients with differentiated thyroid cancer (DTC after thyroidectomy and radioiodine ablative therapy. In recent years highly sensitive Tg assays have been developed. In this study the analytical performance of the new Roche Elecsys Tg II assay was evaluated and compared with the well documented Access2 Tg assay (Beckman–Coulter. Design and methods: Analytical performance was examined using various Clinical and Laboratory Standards Institute (CLSI evaluation protocols. Tg negative patient sera were used to establish an upper reference limit (URL for the Elecsys Tg II assay. Results: Non-linearity, drift and carry-over according to CLSI EP10 and EP6 in a measuring range of 0.04–500 ng/mL were non-significant. Total precision according to CLSI EP5 was 10% at a Tg concentration of 0.08 ng/mL. A patient serum comparison performed according to a modified CLSI EP9 protocol showed a significant difference of a factor of approximately 1.4, despite using an identical CRM calibrator. The Elecsys Tg II assay measured Tg with a two-fold higher sensitivity than the Access2 assay. Finally, using human sera without Tg, an URL of 0.05 ng/mL was determined. Conclusions: In our hands the highly sensitive Elecsys Tg II assay shows a good analytical performance and a higher sensitivity compared to the Access2 Tg assay. An URL of 0.05 ng/mL for the Elecsys Tg II assay was determined which may improve the clinical utility of the assay for the detection of residual DTC or disease recurrence.

This paper investigates the motion of two infinitesimal masses on the location and stability of the equilibrium points in Robe's restricted problem of 2 + 2 bodies with the bigger primary a Roche ellipsoid and the smaller a triaxial body. We suppose the bigger primary of mass m 1 to be filled with a homogeneous incompressible fluid of density ρ 1. The third and the fourth bodies (of mass m 3 and m 4 respectively) are small solid spheres of density ρ 3 and ρ 4 respectively inside the ellipsoid, with the assumption that the mass and the radius of the third and the fourth body are infinitesimal. We assume that m 2 is describing a circle around m 1. The masses m 3 and m 4 mutually attract each other, do not influence the motion of m 1 and m 2 but are influenced by them. We have taken into consideration all the three components of the pressure field in deriving the expression for the buoyancy force viz (i) due to the own gravitational field of the fluid (ii) that originating in the attraction of m 2 (iii) that arising from the centrifugal force. In this paper, equilibrium solutions of m 3 and m 4 and their linear stability are analyzed.

Genotypes of hepatitis C virus (HCV) are distributed differently across the world. There is a paucity of such data in a multi-ethnic Asian population like Malaysia. The objectives of this study were to determine the distribution of HCV genotypes between major ethnic groups and to ascertain their association with basic demographic variables like age and gender. This was a cross-sectional prospective study conducted from September 2007 to September 2013. Consecutive patients who were detected to have anti-HCV antibodies in the University of Malaya Medical Centre were included and tested for the presence of HCV RNA using Roche Cobas Amplicor Analyzer and HCV genotype using Roche single Linear Array HCV Genotyping strip. Five hundred and ninety-six subjects were found to have positive anti-HCV antibodies during this period of time. However, only 396 (66.4%) were HCV RNA positive and included in the final analysis. Our results showed that HCV genotype 3 was the predominant genotype with overall frequency of 61.9% followed by genotypes 1 (35.9%), 2 (1.8%) and 6 (0.5%). There was a slightly higher prevalence of HCV genotype 3 among the Malays when compared to the Chinese (P=0.043). No other statistical significant differences were observed in the distribution of HCV genotypes among the major ethnic groups. There was also no association between the predominant genotypes and basic demographic variables. In a multi-ethnic Asian society in Malaysia, genotype 3 is the predominant genotype among all the major ethnic groups with genotype 1 as the second commonest genotype. Both genotypes 2 and 6 are uncommon. Neither genotype 4 nor 5 was detected. There is no identification of HCV genotype according to ethnic origin, age and gender.

The aim of the present study was to evaluate the performance of three in-house PCR techniques for HBV DNA detection and compare it with commercial quantitative methods to evaluate the usefulness of in-house methods for HBV diagnosis. Three panels of HBsAg reactive sera samples were evaluated: (i) 50 samples were examined using three methods for in-house qualitative PCR and the Cobas Amplicor HBV Monitor Assay; (ii) 87 samples were assayed using in-house semi-nested PCR and the Cobas TaqMan HBV test; (iii) 11 serial samples obtained from 2 HBV-infected individuals were assayed using the Cobas Amplicor HBV test and semi-nested PCR. In panel I, HBV DNA was detected in 44 samples using the Cobas Amplicor HBV test, 42 samples using semi-nested PCR (90% concordance with Cobas Amplicor), 22 samples using PCR for the core gene (63.6% concordance) and 29 samples using single-round PCR for the pre-S/S gene (75% concordance). In panel II, HBV DNA was quantified in 78 of the 87 HBsAg reactive samples using Cobas TaqMan but 52 samples using semi-nested PCR (67.8% concordance). HBV DNA was detected in serial samples until the 17th and 26th week after first donation using in-house semi-nested PCR and the Cobas Amplicor HBV test, respectively. In-house semi-nested PCR presented adequate concordance with commercial methods as an alternative method for HBV molecular diagnosis in low-resource settings. Copyright © 2015 Elsevier B.V.

L'établissement de cette base de données a permis une synthèse du potentiel pétrolier du pays, la partie concernant le bassin de Madre de Dios, la zone subandine et le Chaco, c'est-à-dire toute la zone potentiellement pétrolière du pays, hors Altiplano, est ici présentée. La base contient actuellement les analyses d'un peu plus de 3000 échantillons. Les roches mères sont Paléozoïques et se sont déposées dans un contexte de bassin d'avant-pays; celui ci s'étendait sur la cordillère ainsi que sur l'avant-pays actuel du Silurien au Permien. Le bassin, restreint initialement à la zone sud-ouest, s'est ensuite étendu vers le nord. La bordure ouest n'est pas connue, elle devait se situer au niveau de l'Altiplano actuel. La bordure est correspond au bouclier Brésilien affleurant actuellement à l'est du pays et sur laquelle se biseaute le Paléozoique.

Neisseria gonorrhoeae is an important sexually transmitted diseases (STD) causing pathogen worldwide. Due to absence of an affordable diagnostic assay, routine screening of gonococcal infection becomes impossible in developing countries where infection rates are maximum. Treatment is given on the basis of symptoms alone which leads to spread of infection. Thus, development of a rapid, sensitive, specific, and PCR based visual diagnostic assay suitable for developing countries, required for better disease management, is aimed at in present study. Endocervical swabs were collected from patients visiting gynecology department of various hospitals in Delhi. In-house PCR based assay was developed and modified to visual assay using molecular beacon for end-point detection. It was evaluated against Roche AMPLICOR NG kit and rmp gene. Specificity of beacon was confirmed by competition experiments. Diagnostic test was 98.21% specific and 99.59% sensitive whereas negative and positive predicted value were 99.40% and 98.78%, respectively. We also observed that twice the concentration (2X) of premix was stable at 4°C for 4 months and dry swab samples gave concordant results with that of wet swabs. These features make the test best suitable for routine diagnosis of genital infections in developing countries. PMID:25802857

Diagnosis of neonatal sepsis remains a major challenge in neonatology. Most molecular-based methods are not customized for neonatal requirements. The aim of the present study was to assess the diagnostic accuracy of a modified multiplex PCR protocol for the detection of neonatal sepsis using small blood volumes. 212 episodes of suspected neonatal late onset sepsis were analyzed prospectively using the Roche SeptiFast® MGRADE PCR with a modified DNA extraction protocol and software-handling tool. Results were compared to blood culture, laboratory biomarkers and clinical signs of sepsis. Of 212 episodes, 85 (40.1%) were categorized as "not infected". Among these episodes, 1 was false positive by blood culture (1.2%) and 23 were false positive by PCR (27.1%). Of 51 (24.1%) episodes diagnosed as "culture proven sepsis", the same pathogen was detected by blood culture and PCR in 39 episodes (76.5%). In 8 episodes, more pathogens were detected by PCR compared to blood culture, and in 4 episodes the pathogen detected by blood culture was not found by PCR. One of these episodes was caused by Bacillus cereus, a pathogen not included in the PCR panel. In 76/212 (35.8%) episodes, clinical sepsis was diagnosed. Among these, PCR yielded positive results in 39.5% of episodes (30/76 episodes). For culture-positive sepsis, PCR showed a sensitivity of 90.2% (95%CI 86.2-94.2%) and a specificity of 72.9% (95%CI 67.0-79.0%). The Roche SeptiFast® MGRADE PCR using a modified DNA extraction protocol showed acceptable results for rapid detection of neonatal sepsis in addition to conventional blood culture. The benefit of rapid pathogen detection has to be balanced against the considerable risk of contamination, loss of information on antibiotic sensitivity pattern and increased costs.

A highly sensitive second-generation hepatitis C virus (HCV) core antigen assay has recently been developed. We compared viral disappearance and first-phase kinetics between commercially available core antigen (Ag) assays, Lumipulse Ortho HCV Ag (Lumipulse-Ag), and a quantitative HCV RNA PCR assay, Cobas Amplicor HCV Monitor test, version 2 (Amplicor M), to estimate the predictive benefit of a sustained viral response (SVR) and non-SVR in 44 genotype 1b patients treated with interferon (IFN) and ribavirin. HCV core Ag negativity could predict SVR on day 1 (sensitivity = 100%, specificity = 85.0%, accuracy = 86.4%), whereas RNA negativity could predict SVR on day 7 (sensitivity = 100%, specificity = 87.2%, accuracy = 88.6%). None of the patients who had detectable serum core Ag or RNA on day 14 achieved SVR (specificity = 100%). The predictive accuracy on day 14 was higher by RNA negativity (93.2%) than that by core Ag negativity (75.0%). The combined predictive criterion of both viral load decline during the first 24 h and basal viral load was also predictive for SVR; the sensitivities of Lumipulse-Ag and Amplicor-M were 45.5 and 47.6%, respectively, and the specificity was 100%. Amplicor-M had better predictive accuracy than Lumipulse-Ag in 2-week disappearance tests because it had better sensitivity. On the other hand, estimates of kinetic parameters were similar regardless of the detection method. Although the correlations between Lumipulse-Ag and Amplicor-M were good both before and 24 h after IFN administration, HCV core Ag seemed to be relatively lower 24 h after IFN administration than before administration. Lumipulse-Ag seems to be useful for detecting the HCV concentration during IFN therapy; however, we still need to understand the characteristics of the assay.

Apports de l’archéobotanique à la compréhension de la Source des Roches, Chamalières (Puy-de-Dôme The archaeobotanic contribution to the understanding of la Source des Roches, Chamalières (Puy-de-Dôme

Full Text Available Au tout début de la période romaine, un taux d’arbres inhabituellement élevé a été mis en évidence par la palynologie sur le site de la Source des Roches à Chamalières (Puy-de-Dôme, gisement qui a livré plus de 3500 ex-voto en bois au début des années 70. Durant le second âge du Fer et l’époque romaine, un tel niveau de boisement n’est observé nulle part ailleurs, ni en plaine de Limagne, ni sur le plateau des Dômes. L’hypothèse d’un sanctuaire de plein air, soutenue par Anne-Marie Romeuf qui a dirigé la fouille, se trouve ainsi confortée par l’analyse pollinique, qui permet d’envisager la possibilité de la présence d’un « bois sacré » composé principalement de chênes. La combinaison des données archéobotaniques issues de la palynologie et de la carpologie contribue à renforcer la compréhension du site d’un point de vue paysager et nous renseigne également sur les types d’offrandes végétales associées au dépôt des ex-voto.Unusually high levels of tree pollen were revealed by palynology on the site of the Source des Roches in Chamalières (Puy-de-Dôme for the very beginning of the Roman period. The site had yielded more than 3500 wooden offerings in the early 70s. Such a high density of woodland can be found nowhere else for the Second Iron Age and the Roman period, neither in the plain of Limagne, nor on the plateau of Les Dômes. The hypothesis of an open air sanctuary, first advanced by Anne-Marie Romeuf, director of excavation, is therefore reinforced by the pollen analysis which leads us to consider the possibility that a “sacred grove” made up principally of oaks was present. The correlation of the archaeobotanic data from palynology and paleœthnobotany contributes to the strengthening of the site’s knowledge from the landscape’s point of view. We also have a better understanding of the vegetal offerings associated with the wooden statues.

Vitamin B(12) being water soluble is excreted in the urine when administered in excess. The probability of finding an abnormally excess serum concentration would be almost surreal. We report a peculiar clinical situation that may impact the vitamin B(12) immunoassay on the Roche Elecsys 2010 due to excess analyte concentration. In separate episodes (Feb and June 2010), the Biochemistry laboratory of a tertiary-care hospital, Kolkata, India, encountered two critically ill patients with background chronic kidney disease (CKD), low urine output, and on cyanocoabalamin supplementation, who had serum vitamin B(12) concentrations far exceeding expected values; even post dialysis. The B(12) assays (pmol/l) were performed using electrochemiluminiscence immunoassay on Roche Elecsys 2010, the assay validity confirmed by concomitant quality control runs. The immunoassays failed to deliver results, flagged with "signal level below limit". Biotin therapy was ruled out as a possible interferent. In the first episode, re-assay of a repeat draw yielded same outcome; outsourcing on Immulite provided concentration of >738 pmol/l. Serial dilution gave result of >29520 pmol/l on Elecsys 2010. In the second, we gained from past experience. Vitamin B(12) concentration >59040 pmol/l was conveyed to the treating nephrologist the very day. The B(12) immunoassay on the Elecsys 2010 employs sequential incubation steps for competitive binding that is compromised in the event of abnormally excess B(12) concentration in patient sera akin to the prozone effect. This knowledge may be beneficial while assaying sera of CKD patients to avoid financial loss due unnecessary repeats and delay in turnaround time.

L-thyroxine (L-T4 was started and titrated up to 75 μg, once daily, with clinical improvement. Other investigations revealed very high titres of anti-thyroid peroxidase (anti-TPO and anti-thyroglobulin (anti-Tg antibodies. After three months, there was a fall in TSH to 12.74 μIU/ml, however, with unexpectedly high free T4 (FT4 - 6.8 ng/ml and free T3 (FT3 - 6.7 pg/ml concentrations [reference range (rr: 0.8-1.9 ng/ml and 1.5-4.1 pg/ml (Siemens®, respectively]. At this stage L-T4 was stopped, and this was followed by a rapid increase in TSH (to 77.76 μIU/ml and some decrease in FT4 and FT3, however FT4 concentration remained elevated (2.1 ng/ml. Following this, L-T4 was restarted. On admission to our Department, she was clinically euthyroid on L-T4, 88 μg, once daily. Investigations on Roche® platform confirmed mildly elevated TSH - 5.14 (rr: 0.27-4.2 μIU/ml with high FT4 [4.59 (rr: 0.93-1.7 ng/ml] and FT3 [4.98 (rr: 2.6-4.4 pg/ml] concentrations. Other tests revealed hypoechogenic ultrasound pattern typical for Hashimoto thyroiditis. There was no discrepancy in calculated TSH value following TSH dilution (101% recovery. Concentrations of FT4 and FT3 were assessed on the day of discontinuation of L-T4 and after four days by the means of Abbott® Architect I 1000SR platform. These revealed FT4 and FT3 concentrations within the reference range [e.g., FT4 - 1.08 ng/ml (rr: 0.7-1.48] vs 4.59 ng/ml (rr: 0.93-1.7, Roche®, FT3 - 3.70 pg/ml (rr: 1.71-3.71 vs 4.98 (rr: 2.6-4.4, Roche®], confirming assay interference. Concentrations of ferritin and SHBG were normal. Conclusions Clinicians must be aware of possible assay interference, including the measurements of FT4 and FT3 in the differential diagnosis of abnormal results of thyroid function tests that do not fit the patient clinical

To investigate the performance of the commercial Roche COBAS AmpliScreen assay, and demonstrate whether the COBAS AmpliScreen human immunodeficiency virus-1 (HIV-1) test, v1.5, and COBAS AmpliScreen hepatitis C virus (HCV) v 2.0 for screening for HIV-1 and HCV RNA in the donated blood units from which plasma mini pools were collected, by nucleic acid amplification technology (NAT), could detect the positive pools and reduce the risk of transmission of infections for those routinely tested by serological assays. The study was performed on 3288 plasma samples collected from blood donors in a period of 13 months, from August 2004 to August 2005, at Al-Hada Armed Forces Hospital, Molecular Pathology Laboratory, Taif, Kingdom of Saudi Arabia. The samples were tested by the reverse transcriptase polymerase chain reaction (RT-PCR) after RNA extraction (this represents the major method in NAT assays), in parallel with the routine serological testing to detect qualitatively for HIV-1 and HCV. The NAT assays that include an automated COBAS AmpliPrep system for RNA extraction and COBAS Amplicor Analyzer using AmpliScreen kits for RT-PCR assays, and the routine serological screening assays for the detection of the HIV-1 and HCV RNA in the plasma samples from the blood donors have shown to be a reliable combination that would meet our requirements. The collected data further confirms the results from the serological assays and enables us to decrease the residual risk of transmission to a minimum with the finding of no seronegative window period donation. The results demonstrate that out of 3288 samples, the percentages of RT-PCR (NAT) negative blood donations that were also confirmed as seronegative were 99% for HCV, and 99.1% for HIV-1. The modified combined systems (automated COBAS AmpliPrep system for RNA extraction and COBAS Amplicor Analyzer using AmpliScreen kits for RT-PCR assays) for NAT screening assays has allowed the release of all blood donations supplied in the

Developing Disease-Modifying Treatments in Alzheimer's Disease - A Perspective from Roche and Genentech.

Science.gov (United States)

Doody, R

2017-01-01

Alzheimer's disease (AD) is a chronic neurodegenerative disease for which no preventative or disease-modifying treatments currently exist. Pathological hallmarks include amyloid plaques and neurofibrillary tangles composed of hyper-phosphorylated tau protein. Evidence suggests that both pathologies are self-propagating once established. However, the lag time between neuropathological changes in the brain and the onset of even subtle clinical symptomatology means that patients are often diagnosed late when pathology, and neurodegeneration secondary to these changes, may have been established for several years. Complex pathological pathways associated with susceptibility to AD and changes that occur downstream of the neuropathologic process further contribute to the challenging endeavour of developing novel disease-modifying therapy. Recognising this complexity, effective management of AD must include reliable screening and early diagnosis in combination with effective therapeutic management of the pathological processes. Roche and Genentech are committed to addressing these unmet needs through developing a comprehensive portfolio of diagnostics and novel therapies. Beginning with the most scientifically supported targets, this approach includes two targeted amyloid-β monoclonal antibody therapies, crenezumab and gantenerumab, and an anti-tau monoclonal antibody, RO7105705, as well as a robust biomarker platform to aid in the early identification of people at risk or in the early stages of AD. Identification and implementation of diagnostic tools will support the enrolment of patients into clinical trials; furthermore, these tools should also support evaluation of the clinical efficacy and safety profile of the novel therapeutic agents tested in these trials. This review discusses the therapeutic agents currently under clinical development.

Mechanical Properties of Rocks: Pore Pressure and Scale Effects Propriétés mécaniques des roches : pression de pore et effets d'échelle

Gueguen Y.

2006-12-01

Full Text Available Pore pressure plays a major role when considering rocks mechanical properties. In that field, the concept of effective pressure is a key one to deal with fluids mechanical effects. However, its frequent use has been the source of frequent confusing statements. Because of the various meanings which have been attached to that concept, an attempt is made in this paper to clarify it and examine the validity of its various uses relative to rock mechanical behaviour or rock properties. At a macroscopic scale, thermodynamics provides a powerful tool to investigate this. Reversible or irreversible thermodynamics provide general relationships of great interest. But because real rocks are non homogeneous systems, a microscopic approach is also required in order to analyze the mechanical properties from a description of the small scale processes. The microscopic approach is complementary of the macroscopic thermodynamic one as it leads to the calculation of the effective properties of the medium. In this last approach, effective medium theory is a powerful tool. The effective properties as derived from the microscale can be nicely combined to thermodynamic relations to interpret pore fluid pressure effects and scale effects. The example of elastic properties of porous rocks is more specifically emphasized to illustrate this because of both its intrinsic interest and importance as far as applications are concerned. La pression de pore joue un rôle de première importance dans la considération des propriétés mécaniques des roches. Dans ce domaine, le concept de contrainte effective est essentiel pour aborder les effets mécaniques. Toutefois, son utilisation fréquente a conduit à de nombreuses affirmations trompeuses. Compte tenu des significations diverses accordées à ce concept, nous tentons ici de le clarifier et examinons le domaine d'application de ses divers emplois dans le cadre du comportement mécanique ou des propriétés des roches.

A fundamental to global tuberculosis (TB) control is timely and accurate diagnosis of infectious cases of the disease. Among various methods, techniques based on nucleic acid amplification are the ones with promising prospects. The present study evaluates the diagnostic value of the recently developed IS6110-based loop-mediated isothermal amplification (LAMP) for detection of Mycobacterium tuberculosis complex (MTBC) in sputum specimens. In this cross-sectional study (2008-2009), IS6110-LAMP was evaluated on 101 sputum specimens from 93 highly suspected TB patients and compared to Amplicor MTB test and in-house IS6110-PCR and -nested PCR assays. Culture results or clinical recovery following anti-TB therapy was considered as a reference to prove the TB cases. The overall sensitivity of IS6110-LAMP, Amplicor, nPCR, and PCR were respectively 89.6% (69/77 specimens; 95% confidence interval [CI], 80.5-95.4%), 76.6% (59/77 specimens; CI, 65.6-85.5%), 79.2% (61/77 specimens; CI, 68.5-87.6%) and 59.7% (46/77 specimens; CI, 47.9-70.8%). The specificity and positive predictive value (PPV) were 100% for all the tests, and the negative predictive value (NPV) of IS6110-LAMP, Amplicor, nPCR, and PCR were respectively 75%, 57.1%, 60%, and 43.6%. There was an excellent overall agreement between LAMP and nPCR (k 0.828), and between LAMP and Amplicor (k 0.746), in addition to a better tolerance of IS6110-LAMP to inhibitors present in clinical specimens. The better diagnostic performance of IS6110-LAMP compared to Amplicor (p = 0.009), nPCR (p = 0.013) and PCR (p < 0.0001) besides its rapidity, simplicity, and cost-effectiveness makes it a valuable method for the detection of MTBC in clinical samples, particularly in resource-limited settings.

Development of primary prevention of cervical cancer in other words a vaccination against selected, oncogenic HPV types, entails an increasing importance of epidemiological studies and prevalence of various types of human papilloma virus. The incidence of HPV varies depending on the geographic location of the population. The effectiveness of primary prevention against HPV 16, 18, in the context of reducing the incidence of cervical cancer will depend, among others, on the prevalence of these types in the population and virus-like antigens, which are partially cross-resistant. Identification of the most frequent, oncogenic HPV types in women with HG SIL diagnosis from Central and Western Poland to assess the merits of the development of primary prevention. For the purpose of molecular tests identifying the presence of 13 DNA oncogenic virus types, swabs were taken with the cyto-brush from 76 women diagnosed with CIN 2 or CIN 3 (HG SIL). Patients eligible for the study were diagnosed at the Laboratory of Pathophysiology of Uterine Cervix, Gynecology and Obstetrics Clinical Hospital of Karol Marcinkowski University of Medical Sciences. Patients came from Central and Western parts of Poland. Cell material in which the method of Amplicor HPV (Roche Diagnostics) identified the presence of DNA of oncogenic HPV types was in each case subsequently subjected to genotyping using the molecular test - Linear Array HPV Genotyping (Roche Diagnostics). Five most common oncogenic HPV types in order of detection included: 16, 33, 18, 31, 56. Together these five types of virus comprised 75.86% (88/116) of all detected HPV types. 1. In women from Central and Western Poland, diagnosed with HG SIL, the most common HPV genotypes were HPV 16, HPV33, HPV 18, HPV31, HPV56. 2. Two HPV types 16 and 18, against which vaccinations are directed, belong to the group of three genotypes of HPV most commonly identified in the evolution of CIN 2, CIN 3 diagnosed in women from Central and Western

Objective: To evaluate the virological response to treatment with interferon and ribavirin in-patients with hepatitis C related liver disease. Material and Methods: Two hundred seventy-nine patients were included in the study. These patients had taken interferon and ribavirin treatment for HCV related chronic hepatitis, and were referred to AFIP for HCV RNA testing by polymerase chain reaction (PCR) between January 2002 and September 2002. Out of 279 cases, 229 had taken the treatment for 06 or 12 months and were tested for end-of-treatment response (ETR). Fifty patients had completed there treatment regimens of 6 or 12 months treatment, at least 24 weeks before their PCR test and were having follow-up testing for sustained viral response (SVR). The sera of these patients were tested for HCV RNA by PCR, using a commercial kit of Amplicor (Roche) for qualitative detection of HCV RNA. Results: Out of 229 cases tested for end-of-treatment response, 198 (86.5%) had no detectable HCV RNA (responders) and 31 (13.50%) were PCR positive (non-responders). Thirty-eight out of 50 cases, tested for a sustained viral response, had a negative result for HCV PCR thus showing sustained response rate of 76%. Conclusion: The viral remission/response to interferon and ribavirin combination therapy in our patients was better than that quoted in other regions. (author)

Measurement of viral load in human immunodeficiency virus type 1 (HIV-1) infected patients is essential for the establishment of a therapeutic strategy. Several assays based on qPCR are available for the measurement of viral load; they differ in sample volume, technology applied, target gene, sensitivity and dynamic range. The Bioneer AccuPower® HIV-1 Quantitative RT-PCR is a novel commercial kit that has not been evaluated for its performance. This study aimed to evaluate the performance of the Bioneer AccuPower® HIV-1 Quantitative RT-PCR kit. In total, 288 EDTA plasma samples from the Dharmais Cancer Hospital were analyzed with the Bioneer AccuPower® HIV-1 Quantitative RT-PCR kit and the Roche COBAS? AmpliPrep/COBAS® TaqMan® HIV-1 version 2.0 (CAP/CTM v2.0). The performance of the Bioneer assay was then evaluated against the Roche CAP/CTM v2.0. Overall, there was good agreement between the two assays. The Bioneer assay showed significant linear correlation with CAP/CTM v2.0 (R2=0.963, plaboratories.

Definitive diagnosis of HIV infection in infants mothers is still posing some difficulty in Nigeria and other developing countries. Within this age definitive diagnosis can only be carried out by antigen based techniques which are indeed not available in these developing countries. This has resulted in the absence of authoritative data on the rate of mother-to-child transmission in these countries. Nigeria inclusive. The present pilot study was therefore carried out to generate some information on the rate of mother to child transmission in Nigeria using the PCR technique. Plasma samples were obtained from 68 children of both sexes less than 18 months of age and who were born to HIV infected mothers. The samples were collected from two pediatric departments. in Lagos and in Benin. The presence of HIV 1 RNA in each of the samples. was determined using the Amplicor Monitor V 1.5 technique (Roche Diagnostics). Data showed that HIV-1 RNA was detected in 15 of the 68 samples tested. This gave an HIV-1 RNA detection rate of 22%. Among women who had some intervention, the rate of transmission of infection was 11% while the rate among those without intervention was 30%. The 22% transmission rate recorded in this study is close to the range of 25 to 35% that has been reported in several developed and a few developing countries. A multicenter nationwide study will still be needed to determine the national mother to child transmission rate in Nigeria.

The present retrospective study was initiated to determine the prevalence of Chlamydia trachomatis and to assess the risk factors for infection in adult women and men presenting to general practitioners, gynecologists, dermatologists, and family-planning centers in Greece. The study was carried out in four different Greek hospital centers using highly sensitive nucleic acid amplification techniques. Altogether, 16,834 women and 1,035 men were enrolled from October 1998 to April 2004. Two types of specimens were collected from each patient: cervical swabs from women, urethral swabs from men, and first-catch urine from women and men. All specimens were examined with the Cobas Amplicor C. trachomatis polymerase chain reaction assay (Roche Molecular Systems, Branchburg, NJ, USA) or the LC x C. trachomatis ligase chain reaction assay (Abbott Laboratories, Abbott Park, IL, USA). Demographic and behavioral data were collected by clinicians using a standardized questionnaire. A total of 704 (3.9%) patients were infected with C. trachomatis. The prevalence among female patients was 3.5% and that among male patients 11.2%. Among infected patients, 88% were under 30 years of age, 71% reported more than one sexual partner, and 91% reported a new sexual partner within the last year. In conclusion, the prevalence of C. trachomatis infection in Greece is low. Young age and new and multiple sexual partners within the last year were factors consistently associated with an increased risk of chlamydial infection.

2006-07-15

B-type natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) are small cardiac hormones released from the heart. They can be used as an important aid to diagnose congestive heart failure (CHF). We compared the performances of the Abbott AxSYM and Roche Elecsys 2010 for the measurement of BNP and NT-proBNP. The first method uses a microparticle enzyme-linked immunoassay, whereas the other uses chemiluminescent immunometric assay. The CVs using pooled sera ranged from 3.7% to 12.7% for the AxSYM and 0.9% to 2.2% for the Elecsys 2010. The Passing and Bablok regression was Elecsys 2010 NT-proBNP=7.23xAxSYM BNP+2.53. The BNP in EDTA plasma was more stable than in serum. The immunoreactivity difference of NT-proBNP in serum or EDTA plasma was within 10% when stored at 4 degrees Celsius or 25 degrees Celsius for 72 h. Receiver operating characteristic (ROC) curves were different for both assays, and the areas under the curves were 0.704 and 0.841 for the AxSYM and Elecsys 2010 method, respectively. Both assays were not entirely specific for heart failure. The precision and stability for NT-proBNP was better than for BNP in serum. It is important to use method-appropriate reference ranges (or cutoff) for the BNP and NT-proBNP, respectively, in the assessment of CHF.

Pour les hydrocarbures, tant saturés qu'aromatiques, le facteur essentiel est l'agitation du milieu d'extraction ; la nature du solvant n'est pas critique, à condition de ne pas choisir un très mauvais solvant des hydrocarbures : l'extractibilité est en effet plus fonction du pouvoir désorbant vis-à-vis de la roche que du pouvoir solvant proprement dit. Pour les résines et asphalténes, l'interprétation des résultats est délicate, car la frontière n'est pas nette entre produits simplement dissous, produits de solvolyse et, produits de néoformation par interaction solvant-matière organique-matière minérale.

Monitoring the residual risk of transfusion-transmitted viral infections is important to evaluate the improvement achieved in the blood donation safety and to adopt policies to reduce risks. The present study calculates the incidence of the key infectious diseases, human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) as well as the residual risk of transfusion-transmitted viral infections, during twelve years, 1999 through 2010. Data were analyzed over 3 periods of 4 years (1999-2002, 2003-2006 and 2007-2010). The risk estimates were compared to those previously obtained for blood donations occurred between 1991 and 1998. The study included 209 640 blood donations, from 42 634 regular, volunteers and unpaid donors. The residual risk of transfusion-transmitted infection per million donations was calculated, for each virus, through mathematical model "Incidence rate/window period", described by Schreiber et al. All donations were screened according to Portuguese legislation. In January 2001, the nucleic acid testing in minipool was implemented on all blood donations, for screening simultaneously HIV-1 and HCV ribonucleic acid (RNA) (Cobas Amplicor Ampliscreen-Roche©). This test was replaced, in January 2007, by the simultaneous screening of HBV deoxyribonucleic acid, HCV RNA and HIV-1/HIV-2 RNA, in minipool (Cobas Taqscreen MPX Test-Roche©). The residual risk of transmitting viral infections during the transfusion of blood components is very small and has declined over the years. After the implementation of the nucleic acid testing in minipool for the three viruses, the risk of giving blood during an infectious window period was estimated as follows: for human immunodeficiency virus, 1 in 1.67 million, for hepatitis C virus 1 in 3.33 million and for hepatitis B virus 1 in 526 000. During the 12 years under study, we found a decrease in residual risk for the three viruses, by a factor around five for human immunodeficiency virus

Full Text Available OBJECTIVES: To estimate Chlamydia trachomatis (CT infection prevalence and associated risk factors among a low-income marginalized urban population in Peru. METHODS: Between April 2003 and April 2005, men and women at high-risk for sexually transmitted infections (STIs were recruited from low-income urban areas in three coastal cities in Peru (Chiclayo, Lima, and Trujillo. Consenting participants were studied using a sero-epidemiologic survey. Urine and vaginal swabs collected from men and women were evaluated using polymerase chain reaction (PCR (COBAS® AMPLICOR (CT/NG Test, Roche Molecular Diagnostics, Branchburg, NJ, USA for CT. RESULTS: Among the 2 440 participants recruited for the study (2 145 men and 295 women, overall prevalence of CT infection was 6.6% (95% CI, 5.6-7.6%: 5.5% (95% CI, 4.5-6.5% in men and 14.9% (95% CI, 11.7-27.1% in women. Chlamydial infection was inversely associated with age and positively associated with HIV infection and dysuria in men. Among women, chlamydial infection was inversely associated with age and positively associated with number of sex partners. CONCLUSIONS: CT infection was common among high-risk men and women in urban coastal Peru. Because chlamydial infection is associated with complications related to female reproduction, including infertility and ectopic pregnancy, interventions to prevent and treat infection and studies to determine the feasibility of population-based screening for CT should be conducted among the high-risk female population.OBJETIVOS: Estimar la prevalencia de la infección por Chlamydia trachomatis y los factores de riesgo asociados en una población marginal urbana de bajos ingresos de Perú.

L’efficacite d’un stockage geologique de CO2 repose sur les proprietes de confinement des roches de couverture. Parmi ces proprietes, les caracteristiques diffusives jouent un role important qui est parfois sous-estime. En effet, la diffusion est un processus lent mais qui peut s’averer non negligeable sur le long terme. De plus, les caracteristiques recherchees pour une roche de couverture, principalement une forte pression d’entree et une faible permeabilite, ne sont pas incompatibles avec des coefficients de diffusion relativement eleves, puisque ces grandeurs sont liees a des caracteristiques geometriques differentes (schematiquement, les tailles de pore pour les unes et la tortuosite pour les autres.

Cervical cancer screening programs are switching from cytology-based screening to high-risk (hr) HPV testing. Only clinically validated tests should be used in clinical practice. To assess the clinical performance of the Roche Linear Array HPV genotyping test (Linear Array) within the VALGENT-3 framework. The VALGENT framework is designed for comprehensive comparison and clinical validation of HPV tests that have limited to extended genotyping capacity. The Linear Array enables type-specific detection of 37 HPV types. For the purpose of this study, Linear Array results were designated as positive only if one of the 13 hrHPV types also included in the Hybrid Capture 2 (HC2) was detected. The VALGENT-3 framework comprised 1600 samples obtained from Slovenian women (1300 sequential cases from routine cervical cancer screening enriched with 300 cytological abnormal samples). Sensitivity for cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) (n=127) and specificity for Linear Array and for HC2 and non-inferiority of Linear Array relative to HC2 was checked. In addition, the prevalence of separate hrHPV types in the screening population, as well as the concordance for presence of HPV16, HPV18 and other hrHPV types between Linear Array and the Abbott RealTime High Risk HPV test (RealTime) were assessed. The clinical sensitivity and specificity for CIN2+ of the Linear Array in the total study population was 97.6% (95% CI, 93.3-99.5%) and 91.7% (95% CI, 90.0-93.2%), respectively. The relative sensitivity and specificity of Linear Array vs HC2 was 1.02 [95% CI, 0.98-1.05, (pLinear Array in the screening population was 10.5% (95% CI, 8.9-12.3%) with HPV16 and HPV18 detected in 2.3% and 0.9% of the samples, respectively. Excellent agreement for presence or absence of HPV16, HPV18 and other hrHPV between Linear Array and RealTime was observed. Linear Array showed similar sensitivity with higher specificity to detect CIN2+ compared to HC2. Detection of 13 hrHPV types

The fourth workshop of the OECD/NEA Forum on Stakeholder Confidence (FSC) was hosted by ONDRAF/NIRAS, the Belgian Agency for Radioactive Waste Management and enriched fissile materials. The central theme of the workshop was ''Dealing with interests, values and knowledge in managing risk''within the Belgian context of local partnerships for the long term management of low-level, short-lived radioactive waste. The four-day workshop started with a half-day session in Brussels giving a general introduction on the Belgian context and the local partnership methodology. This was followed by community visits to three local partnerships, PaLoFF in Fleurus-Farciennes, MONA in Mol, and STOLA in Dessel. After the visits, the workshop continued with two full-day sessions in Brussels. One hundred and nineteen registered participants, representing 13 countries, attended the workshop or participated in the community visits. About two thirds were Belgian stakeholders; the remainder came from FSC member organisations. The participants included representatives of municipal governments, civil society organisations, government agencies, industrial companies, the media, and international organisations as well as private citizens, consultants and academics. This Executive Summary gives an overview of the presentations and discussions that took place at the workshop and the community visits. The structure of the Executive Summary follows the structure of the workshop itself. Complementary to this Executive Summary and also provided with this document, is a NEA Secretariat's reflection aiming to place the main lessons of the workshop into an international perspective.

Roche-lobe overflow systems powered by black holes in young star clusters: the importance of dynamical exchanges

Energy Technology Data Exchange (ETDEWEB)

We have run 600 N-body simulations of intermediate-mass (∼3500 M {sub ☉}) young star clusters (SCs; with three different metallicities (Z = 0.01, 0.1, and 1 Z {sub ☉}). The simulations include the dependence of stellar properties and stellar winds on metallicity. Massive stellar black holes (MSBHs) with mass >25 M {sub ☉} are allowed to form through direct collapse of very massive metal-poor stars (Z < 0.3 Z {sub ☉}). We focus on the demographics of black hole (BH) binaries that undergo mass transfer via Roche lobe overflow (RLO). We find that 44% of all binaries that undergo an RLO phase (RLO binaries) formed through dynamical exchange. RLO binaries that formed via exchange (RLO-EBs) are powered by more massive BHs than RLO primordial binaries (RLO-PBs). Furthermore, the RLO-EBs tend to start the RLO phase later than the RLO-PBs. In metal-poor SCs (0.01-0.1 Z {sub ☉}), >20% of all RLO binaries are powered by MSBHs. The vast majority of RLO binaries powered by MSBHs are RLO-EBs. We have produced optical color-magnitude diagrams of the simulated RLO binaries, accounting for the emission of both the donor star and the irradiated accretion disk. We find that RLO-PBs are generally associated with bluer counterparts than RLO-EBs. We compare the simulated counterparts with the observed counterparts of nine ultraluminous X-ray sources. We discuss the possibility that IC 342 X-1, Ho IX X-1, NGC 1313 X-2, and NGC 5204 X-1 are powered by an MSBH.

Computerized summary scoring: crowdsourcing-based latent semantic analysis.

Science.gov (United States)

Li, Haiying; Cai, Zhiqiang; Graesser, Arthur C

2017-11-03

In this study we developed and evaluated a crowdsourcing-based latent semantic analysis (LSA) approach to computerized summary scoring (CSS). LSA is a frequently used mathematical component in CSS, where LSA similarity represents the extent to which the to-be-graded target summary is similar to a model summary or a set of exemplar summaries. Researchers have proposed different formulations of the model summary in previous studies, such as pregraded summaries, expert-generated summaries, or source texts. The former two methods, however, require substantial human time, effort, and costs in order to either grade or generate summaries. Using source texts does not require human effort, but it also does not predict human summary scores well. With human summary scores as the gold standard, in this study we evaluated the crowdsourcing LSA method by comparing it with seven other LSA methods that used sets of summaries from different sources (either experts or crowdsourced) of differing quality, along with source texts. Results showed that crowdsourcing LSA predicted human summary scores as well as expert-good and crowdsourcing-good summaries, and better than the other methods. A series of analyses with different numbers of crowdsourcing summaries demonstrated that the number (from 10 to 100) did not significantly affect performance. These findings imply that crowdsourcing LSA is a promising approach to CSS, because it saves human effort in generating the model summary while still yielding comparable performance. This approach to small-scale CSS provides a practical solution for instructors in courses, and also advances research on automated assessments in which student responses are expected to semantically converge on subject matter content.

The goal of this study was to identify the causes and factors associated with genital ulcer disease (GUD) among patients attending a sexually transmitted disease (STD) clinic in Paris. This study was a prospective investigation of GUD cases. Data were collected from 1995 to 2005. In each case, a Dark Field Examination (DFE), Gram stain, inoculation onto Thayer Martin agar, Columbia agar and chocolate agar with 1% isovitalex and 20% fetal calf serum, PCR Chlamydia trachomatis (Amplicor Roche), culture for herpes simplex virus (HSV) on MRC 5 cells and PCR HSV (Argene Biosoft) were obtained from the ulceration. First Catch Urine (FCU) PCR for Chlamydia trachomatis and syphilis, HIV, HSV, and HBV serologies were also performed. A total 278 cases of GUD were investigated, 244 (88%) in men and 34 (12%) in women. Primary syphilis accounted for 98 cases (35%), genital herpes for 74 (27%), chancroid for 8 (3%), other infections for 12 (5%). In 91 (32%) patients, no identifiable microorganism was documented. Primary syphilis was more prevalent in MSMs (P chancroid were significantly associated with heterosexuality (both P 10 mm (OR: 9.2 [95% CI: 2.9-30.7], P chancroid and reemergence of infectious syphilis have led to a new distribution of pathogens, genital herpes, primary syphilis and GUD from unknown origin, accounting each for one third of cases. No clinical characteristic is predictive of the etiology, underlining the importance of performing a thorough microbiologic evaluation. Close association with HIV is still a major public health problem.

One never quite knows what to say in a summary. If you were at the sessions, you heard the same talks I did. Perhaps the purpose is to summarize the parallel sessions, but like you, I can only attend one of these sessions. In addition, the time is short, so that this cannot be a real summary. What I will present are impressions of the past two days, and these will certainly be colored by my own views. Thus at the outset, let me apologize for any and all omissions and distortions. I will cover primarily the plenary session talks, but will organize this summary along the following lines: 1. vector (V) mesons; 2. pseudoscalar mesons, and 3. other subjects, notably with electrons. This afternoon's talks are so close in time to this summary that I shall omit them. (author)

Low-cost ultra-wide genotyping using Roche/454 pyrosequencing for surveillance of HIV drug resistance.

Directory of Open Access Journals (Sweden)

Dawn M Dudley

Full Text Available Great efforts have been made to increase accessibility of HIV antiretroviral therapy (ART in low and middle-income countries. The threat of wide-scale emergence of drug resistance could severely hamper ART scale-up efforts. Population-based surveillance of transmitted HIV drug resistance ensures the use of appropriate first-line regimens to maximize efficacy of ART programs where drug options are limited. However, traditional HIV genotyping is extremely expensive, providing a cost barrier to wide-scale and frequent HIV drug resistance surveillance.We have developed a low-cost laboratory-scale next-generation sequencing-based genotyping method to monitor drug resistance. We designed primers specifically to amplify protease and reverse transcriptase from Brazilian HIV subtypes and developed a multiplexing scheme using multiplex identifier tags to minimize cost while providing more robust data than traditional genotyping techniques. Using this approach, we characterized drug resistance from plasma in 81 HIV infected individuals collected in São Paulo, Brazil. We describe the complexities of analyzing next-generation sequencing data and present a simplified open-source workflow to analyze drug resistance data. From this data, we identified drug resistance mutations in 20% of treatment naïve individuals in our cohort, which is similar to frequencies identified using traditional genotyping in Brazilian patient samples.The developed ultra-wide sequencing approach described here allows multiplexing of at least 48 patient samples per sequencing run, 4 times more than the current genotyping method. This method is also 4-fold more sensitive (5% minimal detection frequency vs. 20% at a cost 3-5× less than the traditional Sanger-based genotyping method. Lastly, by using a benchtop next-generation sequencer (Roche/454 GS Junior, this approach can be more easily implemented in low-resource settings. This data provides proof-of-concept that next

Les résultats obtenus sont ensuite comparés à ceux de l'analyse plastique par la théorie des charges limites. Cette étude met en évidence l'existence de deux modes de rupture, l'action différente du frottement superficiel selon le sens de l'écoulement relatif du matériau en contact, le phénomène de la ductilité apparente qui dépend de la forme de l'outil ; elle précise les paramètres mécaniques importants du forage. A detailed experimental investigation of the local process of rock cutting by a drill bit was carried out on soft equivalent materials simulating rock under borehole conditions. Different factors were analyzed : the shape of the bit tooth, the roughness of ifs contact area, the average ductility of the materiat. The results obtained are then compared with those from a plastic analysis based on the peak lood theory. This investigation shows that there are two different modes of rock destruction, that the Coulomb friction has a different effect depending on the relative direction of flow of the materiat in contact with the bit, and that an apparent ductility of the materiat is linked to the shape of the bit teeth. Finally, the basic mechanical variables for drilling are described

Analysis of 16S rRNA amplicon sequencing options on the Roche/454 next-generation titanium sequencing platform.

Directory of Open Access Journals (Sweden)

Hideyuki Tamaki

Full Text Available BACKGROUND: 16S rRNA gene pyrosequencing approach has revolutionized studies in microbial ecology. While primer selection and short read length can affect the resulting microbial community profile, little is known about the influence of pyrosequencing methods on the sequencing throughput and the outcome of microbial community analyses. The aim of this study is to compare differences in output, ease, and cost among three different amplicon pyrosequencing methods for the Roche/454 Titanium platform METHODOLOGY/PRINCIPAL FINDINGS: The following three pyrosequencing methods for 16S rRNA genes were selected in this study: Method-1 (standard method is the recommended method for bi-directional sequencing using the LIB-A kit; Method-2 is a new option designed in this study for unidirectional sequencing with the LIB-A kit; and Method-3 uses the LIB-L kit for unidirectional sequencing. In our comparison among these three methods using 10 different environmental samples, Method-2 and Method-3 produced 1.5-1.6 times more useable reads than the standard method (Method-1, after quality-based trimming, and did not compromise the outcome of microbial community analyses. Specifically, Method-3 is the most cost-effective unidirectional amplicon sequencing method as it provided the most reads and required the least effort in consumables management. CONCLUSIONS: Our findings clearly demonstrated that alternative pyrosequencing methods for 16S rRNA genes could drastically affect sequencing output (e.g. number of reads before and after trimming but have little effect on the outcomes of microbial community analysis. This finding is important for both researchers and sequencing facilities utilizing 16S rRNA gene pyrosequencing for microbial ecological studies.

Key frame extraction is an efficient way to create the video summary which helps users obtain a quick comprehension of the video content. Generally, the key frames should be representative of the video content, meanwhile, diverse to reduce the redundancy. Based on the assumption that the video data are near a subspace of a high-dimensional space, a new approach, named as key frame extraction in the summary space, is proposed for key frame extraction in this paper. The proposed approach aims to find the representative frames of the video and filter out similar frames from the representative frame set. First of all, the video data are mapped to a high-dimensional space, named as summary space. Then, a new representation is learned for each frame by analyzing the intrinsic structure of the summary space. Specifically, the learned representation can reflect the representativeness of the frame, and is utilized to select representative frames. Next, the perceptual hash algorithm is employed to measure the similarity of representative frames. As a result, the key frame set is obtained after filtering out similar frames from the representative frame set. Finally, the video summary is constructed by assigning the key frames in temporal order. Additionally, the ground truth, created by filtering out similar frames from human-created summaries, is utilized to evaluate the quality of the video summary. Compared with several traditional approaches, the experimental results on 80 videos from two datasets indicate the superior performance of our approach.

2006-11-01

Full Text Available L'objectif essentiel de cette recherche était de mettre au point une méthode expérimentale pour étudier l'anisotropie de la vitesse des ondes longitudinales (P dans les roches. Cette anisotropie aurait deux causes principales : d'une part, l'existence d'un réseau de pores, de fissures ou de microfissures, distribué de façon anisotrope dans la roche et d'autre part, la structure elle-même, dont l'anisotropie résulte de la nature des minéraux et de leur disposition. Dans un premier temps, nous avons commencé les essais sur des échantillons de carotte, forés dans trois directions perpendiculaires X, Y et Z d'un bloc de deux types de grès : grès des Vosges et grès de Fontainebleau. La vitesse du son a été mesurée sur 3 à 4 sections de carotte avec des intervalles de 30° (6 directions. Elles se distribuent nettement selon une ellipse, appelée l'ellipse d'anisotropie. Ces ellipses ont été tracées par mini-ordinateur et ont permis de mettre en évidence l'état d'anisotropie et l'homogénéité des carottes. La méthode est tellement précise qu'une erreur de repérage des axes sur un échantillon (Y de grès des Vosges a été détectée et certifiée à l'aide de direction des micas. Nous avons effectué le même essai sur les mêmes échantillons saturés sous vide. Une tendance générale à l'augmentation des vitesses, la diminution du degré d'anisotropie (le rapport de Vmax/Vmin et le changement de position de l'axe d'anisotropie a été observée.

Studies have shown that low-frequency resistance mutations can influence treatment outcome. However, the lack of a standardized high-throughput assay has precluded their detection in clinical settings. To evaluate the performance of the Roche prototype 454 UDS HIV-1 drug resistance assay (UDS assay) in a routine diagnostic laboratory. 50 plasma samples, previously characterized by population sequencing and that had shown ≥1 resistance associated mutation (RAM), were retrospectively tested by the UDS assay, including 18 B and 32 non-B subtypes; viral loads between 114-1,806,407 cp/ml; drug-naive (n=27) and drug-experienced (n=23) individuals. The UDS assay was successful for 37/50 (74%) samples. It detected all RAMs found by population sequencing at frequencies above 20%. In addition, 39 low-frequency RAMs were exclusively detected by the UDS assay at frequencies below 20% in both drug-naïve (19/26, 73%) and drug-experienced (9/18, 50%) individuals. UDS results would lead to changes from susceptible to resistant to efavirenz (EFV) in one drug-naive individual with suboptimal response to an EFV-containing regimen and from susceptible to resistance to lamivudine (3TC) in one drug naïve subject who subsequently failed a 3TC-containing regimen and in a treatment experienced subject who had failed a 3TC-containing regimen. The UDS assay performed well across a wide range of subtypes and viral loads; it showed perfect agreement with population sequencing for all RAMs analyzed. In addition, the UDS assay detected additional mutations at frequencies below 20% which correlate with patients' treatment history and had in some cases important prognostic implications.

Uplink is an important part of spacecraft operations. Ensuring the accuracy of uplink content is essential to mission success. Before commands are radiated to the spacecraft, the command and sequence must be reviewed and verified by various teams. In most cases, this process requires collecting the command data, reviewing the data during a command conference meeting, and providing physical signatures by designated members of various teams to signify approval of the data. If commands or sequences are disapproved for some reason, the whole process must be restarted. Recording data and decision history is important for traceability reasons. Given that many steps and people are involved in this process, an easily accessible software tool for managing the process is vital to reducing human error which could result in uplinking incorrect data to the spacecraft. An uplink summary generator called ULSGEN was developed to assist this uplink content approval process. ULSGEN generates a web-based summary of uplink file content and provides an online review process. Spacecraft operations personnel view this summary as a final check before actual radiation of the uplink data. .

Hepatitis C virus (HCV) infection is diagnosed by the presence of antibodies and is supplemented by confirmatory testing methods, such as recombinant immunoblot assay (RIBA) and HCV-RNA detection. This study aimed to evaluate the efficacy of RIBA testing to diagnose HCV infection in blood donors positive for anti-HCV antibodies. A total of 102 subjects positive for anti-HCV determined by enzyme-linked immunosorbent assay (ELISA) at the Hematology and Hemotherapy Foundation of Bahia (HEMOBA) were later assessed with new samples using the Abbott Architect anti-HCV test (Abbott Diagnostics, Wiesbaden, Germany), the RIBA III test (Chiron RIBA HCV 3.0 SIA, Chiron Corp., Emeryville, CA, USA), the polymerase chain reaction (PCR; COBAS® AMPLICOR HCV Roche Diagnostics Corp., Indianapolis, IN, USA) and line probe assay (LiPA - Siemens, Tarrytown, NY, USA) genotyping for HCV diagnosis. Of these new samples, 38.2% (39/102) were positive, 57.8% (59/102) were negative and 3.9% (4/102) were indeterminate for anti-HCV; HCV-RNA was detected in 22.5% (23/102) of the samples. RIBA results were positive in 58.1% (25/43), negative in 9.3% (4/43) and indeterminate in 32.6% (14/43) of the samples. The prevailing genotypes were 1 (78.3%, 18/23), 3 (17.4%, 4/23) and 2 (4.3%, 1/23). All 14 samples with indeterminate RIBA results had undetectable viral loads (detection limit ≤50 IU/mL). Of these samples, 71.4% (10/14) were reevaluated six months later. Eighty percent (8/10) of these samples remained indeterminate by RIBA, and 20% (2/10) were negative. In this study, individuals with indeterminate RIBA results had no detectable HCV-RNA.

Full Text Available Objectives: Laboratory diagnosis of hepatitis C virus (HCV infection is based on the detection of anti-HCV antibodies by enzyme immunoassay (EIA or chemiluminescence immunoassay (CIA techniques. However, a consensus related to the problem of low titer (Serum/Cut-off; S/C= 1.0 anti-HCV antibodies is still lacking. The study attempts to evaluate the clinical status of the patients with low titer anti-HCV antibodies detected by third generation anti-HCV tests during February 2013- May 2014 retrospectively. Methods: Serum samples were studied by Advia Centaur XP autoanalyser (Bayer-Siemens, Germany for anti-HCV, and line immunoassay (Inno-LIATM HCV Score, İnnogenetics, Belgium for anti-HCV confirmatory test, Cobas AmpliPre/Cobas AMPLICOR HCV Test (Roche diagnostics, Switzerland for HCV RNA. Results: A total of 55.631 serum samples were studied, and 55 of them were anti-HCV positive of which with low antibody levels (sample/cutoff [S/CO]. S/CO values ranged from 1.15 to 6.15. Seventeen (31% of patients who have low antibody levels were defined as positive and 2 (4% patients were intermittent and 36 (65% patients were negative with line immunoassay. HCV-RNA was not detected in any of the samples. Conclusions: It is thought that antibody positivity must be verified in cases of recurrent reactivity when considering the cost-effectiveness of molecular tests. In the study was concluded that the use of molecular tests would be appropriate diagnosis, and the effectiveness of treatment if necessary after evaluation of patients with biochemical analysis.

2018-01-01

The International Patient Summary (IPS) standards aim to define the specifications for a minimal and non-exhaustive Patient Summary, which is specialty-agnostic and condition-independent, but still clinically relevant. Meanwhile, health systems are developing and implementing their own variation of a patient summary while, the eHealth Digital Services Infrastructure (eHDSI) initiative is deploying patient summary services across countries in the Europe. In the spirit of co-creation, flexible governance, and continuous alignment advocated by eStandards, the Trillum-II initiative promotes adoption of the patient summary by engaging standards organizations, and interoperability practitioners in a community of practice for digital health to share best practices, tools, data, specifications, and experiences. This paper compares operational aspects of patient summaries in 14 case studies in Europe, the United States, and across the world, focusing on how patient summary components are used in practice, to promote alignment and joint understanding that will improve quality of standards and lower costs of interoperability.

Adams, D C; Bristol, J B; Poskitt, K R

1993-03-01

The problem area of communication between hospital and general practitioners may potentially be improved by the advent of new information technology. The introduction of a regional computer database for general surgery allows the rapid automated production of discharge summaries and has provided us with the opportunity for auditing the quality of old and new styles of discharge communication. A total of 118 general practitioners were sent a postal questionnaire to establish their views on the relative importance of various aspects of patient information and management after discharge. A high response rate (97%) indicated the interest of general practitioners in this topic. The majority (73%) believed that summaries should be delayed no more than 3 days. The structured and shortened new format was preferred to the older style of discharge summary. The older format rarely arrived within an appropriate time and its content was often felt to be either inadequate (35%) or excessive (7%) compared with the new format (8% and 1%, respectively). The diagnosis, information given to the patient, clinic date, list of medications and investigations were considered the more important details in the summary. Improvements in the discharge information were suggested and have subsequently been incorporated in our discharge policy. The use of new information technology, intended to facilitate clinical audit, has improved our ability to generate prompt, well-structured discharge summaries which are accepted by the general practitioners.

The capacity limitations of orientation summary statistics

Science.gov (United States)

Attarha, Mouna; Moore, Cathleen M.

2015-01-01

The simultaneous–sequential method was used to test the processing capacity of establishing mean orientation summaries. Four clusters of oriented Gabor patches were presented in the peripheral visual field. One of the clusters had a mean orientation that was tilted either left or right while the mean orientations of the other three clusters were roughly vertical. All four clusters were presented at the same time in the simultaneous condition whereas the clusters appeared in temporal subsets of two in the sequential condition. Performance was lower when the means of all four clusters had to be processed concurrently than when only two had to be processed in the same amount of time. The advantage for establishing fewer summaries at a given time indicates that the processing of mean orientation engages limited-capacity processes (Experiment 1). This limitation cannot be attributed to crowding, low target-distractor discriminability, or a limited-capacity comparison process (Experiments 2 and 3). In contrast to the limitations of establishing multiple summary representations, establishing a single summary representation unfolds without interference (Experiment 4). When interpreted in the context of recent work on the capacity of summary statistics, these findings encourage reevaluation of the view that early visual perception consists of summary statistic representations that unfold independently across multiple areas of the visual field.

Executive summary

International Nuclear Information System (INIS)

2002-01-01

On 18 May 2001, the Finnish Parliament ratified the Decision in Principle on the final disposal facility for spent nuclear fuel at Olkiluoto, within the municipality of Eurajoki. The Municipality Council and the government has made positive decisions earlier, at the end of 2000, and in compliance with the Nuclear Energy Act, Parliament's ratification was then required. The decision is valid for the spent fuel generated by the existing Finnish nuclear power plants and means that the construction of the final disposal facility is considered to be in line with the overall good of society. Earlier steps included, amongst others, the approval of the technical project by the Safety Authority. Future steps include construction of an underground rock characterisation facility, ONKALO (2003-2004), and application for separate construction and operating licences for the final disposal facility (from about 2010). How did this political and societal decision come about? The FSC Workshop provided the opportunity to present the history leading up to the Decision in Principle (DiP), and to examine future perspectives with an emphasis on stakeholder involvement. This Executive Summary gives an overview of the presentations and discussions that took place at the workshop. It presents, for the most part, a factual account of the individual presentations and of the discussions that took place. It relies importantly on the notes that were taken at the meeting. Most materials are elaborated upon in a fuller way in the texts that the various speakers and session moderators contributed for these proceedings. The structure of the Executive Summary follows the structure of the workshop itself. Complementary to this Summary and also provided with this document, is a NEA Secretariat's perspective aiming to place the results of all discussions, feedback and site visit into an international perspective.

Hospital discharge summaries enable communication between inpatient and outpatient physicians. Despite existing guidelines for discharge summaries, they are frequently suboptimal. The aim of this study was to assess physicians' perspectives about discharge summaries and the differences between summaries' authors (hospitalists) and readers (primary care physicians [PCPs]). A national survey of 1600 U.S. physicians was undertaken. Primary measures included physicians' preferences in discharge summary standardization, content, format, and audience. A total of 815 physicians responded (response rate = 51%). Eighty-nine percent agreed that discharge summaries "should have a standardized format." Most agreed that summaries should "document everything that was done, found, and recommended in the hospital" (64%) yet "only include details that are highly pertinent to the hospitalization" (66%). Although 74% perceived patients as an important audience of discharge summaries, only 43% agreed that summaries "should be written in language that patients…can easily understand," and 68% agreed that it "should be written solely for provider-to-provider communication." Compared with hospitalists, PCPs preferred comprehensive summaries (68% versus 59%, P = 0.002). More PCPs agreed that separate summaries should be created for patients and for provider-to-provider communication than hospitalists (60% versus 47%, P summary" (44% versus 23%, P summary" (60% versus 38%, P summaries should have a standardized format but do not agree on how comprehensive or in what format they should be. Efforts are necessary to build consensus toward the ideal discharge summary.

2011-12-01

Full Text Available This research aimed to find an answer to the question: "Do summary texts produced by teachers have the characteristics that a summary text is supposed to have?” Descriptive method was used in the research. The study group consisted of 55 teachers who work as Turkish Language and Literature teachers at central primary and secondary schools in Burdur. During the research, the essay “Kitap Az Yaşamayı Önler” by Çetin Altan was used as the source text and the summary texts produced by teachers were evaluated using a criteria-based and gradual analysis instrument. At the end of the study, it was determined that the teachers only managed to reach the sufficient level in terms of reconstructing the summary texts through authentic sentences and reflecting the main idea of the source text in the summary texts. However, according to the research results regarding the teachers’ competence in creating a new title for the summary texts, including the source text’s all supporting ideas and important information in the summary texts and providing the summary texts with the capacity of reflecting the source text, it has been observed that the teachers lack the required knowledge and skill

A rapid method of analysis for the physical and chemical determination of the major constituents of silicate rocks is described. Water losses at 100 deg. C and losses of volatile elements at 1000 deg. C are estimated after staying in oven for these temperatures, or by mean of a thermo-balance. The determination of silica is made by a double insolubilization with hydrochloric acid on attack solution with sodium carbonate; total iron and aluminium, both with calcium and magnesium, after ammoniacal precipitation of Fe and Al, are determined on the filtration product of silica by titrimetry-photometry of their complexes with EDTA. The alkalis Na and K by flame spectrophotometry, Mn by colorimetry of the permanganate, and Ti by mean of his complex with H{sub 2}O{sub 2}, are determined on fluosulfuric attack solution. Phosphorus is determined by his complex with 'molybdenum blue' on a fluoro-nitro-boric attack solution; iron is estimated by potentiometry, with the help of bichromate on hydrofluoric solution.

The equilibrium of rubble-pile satellites: The Darwin and Roche ellipsoids for gravitationally held granular aggregates

Science.gov (United States)

Sharma, Ishan

2009-04-01

Many new small moons of the giant planets have been discovered recently. In parallel, satellites of several asteroids, e.g., Ida, have been found. Strikingly, a majority of these new-found planetary moons are estimated to have very low densities, which, along with their hypothesized accretionary origins, suggests a rubble internal structure. This, coupled to the fact that many asteroids are also thought to be particle aggregates held together principally by self-gravity, motivates the present investigation into the possible ellipsoidal shapes that a rubble-pile satellite may achieve as it orbits an aspherical primary. Conversely, knowledge of the shape will constrain the granular aggregate's orbit—the closer it gets to a primary, both primary's tidal effect and the satellite's spin are greater. We will assume that the primary body is sufficiently massive so as not to be influenced by the satellite. However, we will incorporate the primary's possible ellipsoidal shape, e.g., flattening at its poles in the case of a planet, and the proloidal shape of asteroids. In this, the present investigation is an extension of the first classical Darwin problem to granular aggregates. General equations defining an ellipsoidal rubble pile's equilibrium about an ellipsoidal primary are developed. They are then utilized to scrutinize the possible granular nature of small inner moons of the giant planets. It is found that most satellites satisfy constraints necessary to exist as equilibrated granular aggregates. Objects like Naiad, Metis and Adrastea appear to violate these limits, but in doing so, provide clues to their internal density and/or structure. We also recover the Roche limit for a granular satellite of a spherical primary, and employ it to study the martian satellites, Phobos and Deimos, as well as to make contact with earlier work of Davidsson [Davidsson, B., 2001. Icarus 149, 375-383]. The satellite's interior will be modeled as a rigid-plastic, cohesion-less material

Generation of Anomalous Internal Pressures in Source Rocks and Its Role in Driving Petroleum Migration La genèse de pressions internes anormales dans les roches mères et son rôle de poussée dans la migration du pétrole

. La présence de gaz conduit à des comportements très différents et la pression de pores dans les roches mères inférieure à la normale à moins qu'il n'y ait une genèse suffisante de la matière organique en hydrocarbures pour la compenser. En l'absence d'une genèse continue (c'est-à-dire pour le méthane biogénique, le gaz se dissout régulièrement et les pressions chutent considérablement en dessous de la pression hydrostatique. A l'inverse, sur les élévations, les systèmes gazéifères ont tendance à la surpression et la pression peut atteindre la charge de fracturation de la roche. Le craquage thermique des bitumes qui restent dans une roche mère au cours de l'enfouissement va de pair avec une augmentation de volume et, dans un pore isolé, le système des pressions atteint des valeurs élevées. Il suffit qu'un pour cent des bitumes de type huile soit transformé en gaz pour que la pression atteigne la charge pour laquelle la fracturation de la roche est une conséquence inévitable.

Electron and muon physics sessions: Summary

International Nuclear Information System (INIS)

Montgomery, H.E.

1988-06-01

The electromagnetic interaction needs no introduction as a probe of the structure of systems on many scales. The continued use of this technique dominated the sessions on Electron and Muon Physics at the Samoset Meeting. The experimental results continue to stimulate large numbers of theorists and the results on polarized deep inelastic muon scattering and their various interpretations permeated beyond these sessions. The breadth of physics attacked with electrons and muons makes a summary such as this rather peculiar. As one of my nuclear physics friends (I think) commented after my summary, ''it was interesting to see Nuclear Physics from a long distance with the telescope inverted.'' The comment may well be applied to this written version of the summary talk. 21 refs

This report documents the Basic Energy Sciences (BES) Engineering Research Program for fiscal year 1996; it provides a summary for each of the program projects in addition to a brief program overview. The report is intended to provide staff of Congressional committees, other executive departments, and other DOE offices with substantive program information so as to facilitate governmental overview and coordination of Federal research programs. Of equal importance, its availability facilitates communication of program information to interested research engineers and scientists. Each BES Division administers basic, mission oriented research programs in the area indicated by its title. The BES Engineering Research Program is one such program; it is administered by the Engineering and Geosciences Division of BES. In preparing this report the principal investigators were asked to submit summaries for their projects that were specifically applicable to fiscal year 1996. The summaries received have been edited if necessary, but the press for timely publication made it impractical to have the investigators review and approve the revised summaries prior to publication. For more information about a given project, it is suggested that the investigators be contacted directly.

The summary of national environmental restoration needs

International Nuclear Information System (INIS)

1993-07-01

The Office of Technology Development of the US Department of Energy (DOE) has directed the Savannah River Technology Center to implement an Integrated Demonstration Program at Savannah River Site to assess new environmental remediation systems and technologies and transfer them to other DOE sites and private industry for use in full-scale remediation efforts. The first phase of the Integrated Demonstration Program is coming to a successful conclusion and the Savannah River Technology Center has asked a panel of environmental experts to prioritize national, DOE, and Savannah River Site environmental problems and make programmatic recommendations for future technology research and demonstrations. This document is a summary of national and DOE environmental problems that are common to Savannah River Site and was created as a decision making tool for the expert panel. There are many diverse environmental problems, therefore the summary has been limited to environmental problems that are significant to the Savannah River Site. National environmental problems identified in the summary are soil and water contaminated with organic compounds. Specifically, groundwater contaminated with dense non-aqueous phase liquid hydrocarbons was found to be a significant national environmental problem. The DOE environmental problems identified in the summary are soil and water contaminated with fuel and chlorinated hydrocarbon compounds, metal compounds, and radioactive elements. Savannah River Site environmental problems identified in the summary are soil and groundwater contaminated with chlorinated hydrocarbons, metal compounds, tritiated water, and other radioactive elements. Technology deficiencies that were identified in the summary were deficiencies in in situ remediation technologies, in situ characterization technologies, and in situ isolation and containment technologies

Thyroglobulin (Tg) measurements are used to monitor for residual thyroid tissue in patients with differentiated thyroid cancer (DTC) after thyroidectomy and radioiodine ablative therapy. In recent years highly sensitive Tg assays have been developed. In this study the analytical performance of the new Roche Elecsys Tg II assay was evaluated and compared with the well documented Access2 Tg assay (Beckman-Coulter). Analytical performance was examined using various Clinical and Laboratory Standards Institute (CLSI) evaluation protocols. Tg negative patient sera were used to establish an upper reference limit (URL) for the Elecsys Tg II assay. Non-linearity, drift and carry-over according to CLSI EP10 and EP6 in a measuring range of 0.04-500 ng/mL were non-significant. Total precision according to CLSI EP5 was 10% at a Tg concentration of 0.08 ng/mL. A patient serum comparison performed according to a modified CLSI EP9 protocol showed a significant difference of a factor of approximately 1.4, despite using an identical CRM calibrator. The Elecsys Tg II assay measured Tg with a two-fold higher sensitivity than the Access2 assay. Finally, using human sera without Tg, an URL of 0.05 ng/mL was determined. In our hands the highly sensitive Elecsys Tg II assay shows a good analytical performance and a higher sensitivity compared to the Access2 Tg assay. An URL of 0.05 ng/mL for the Elecsys Tg II assay was determined which may improve the clinical utility of the assay for the detection of residual DTC or disease recurrence.

Compact Visualisation of Video Summaries

Directory of Open Access Journals (Sweden)

Janko Ćalić

2007-01-01

Full Text Available This paper presents a system for compact and intuitive video summarisation aimed at both high-end professional production environments and small-screen portable devices. To represent large amounts of information in the form of a video key-frame summary, this paper studies the narrative grammar of comics, and using its universal and intuitive rules, lays out visual summaries in an efficient and user-centered way. In addition, the system exploits visual attention modelling and rapid serial visual presentation to generate highly compact summaries on mobile devices. A robust real-time algorithm for key-frame extraction is presented. The system ranks importance of key-frame sizes in the final layout by balancing the dominant visual representability and discovery of unanticipated content utilising a specific cost function and an unsupervised robust spectral clustering technique. A final layout is created using an optimisation algorithm based on dynamic programming. Algorithm efficiency and robustness are demonstrated by comparing the results with a manually labelled ground truth and with optimal panelling solutions.

Functional summary statistics for the Johnson-Mehl model

DEFF Research Database (Denmark)

Møller, Jesper; Ghorbani, Mohammad

The Johnson-Mehl germination-growth model is a spatio-temporal point process model which among other things have been used for the description of neurotransmitters datasets. However, for such datasets parametric Johnson-Mehl models fitted by maximum likelihood have yet not been evaluated by means...... of functional summary statistics. This paper therefore invents four functional summary statistics adapted to the Johnson-Mehl model, with two of them based on the second-order properties and the other two on the nuclei-boundary distances for the associated Johnson-Mehl tessellation. The functional summary...... statistics theoretical properties are investigated, non-parametric estimators are suggested, and their usefulness for model checking is examined in a simulation study. The functional summary statistics are also used for checking fitted parametric Johnson-Mehl models for a neurotransmitters dataset....

Computer software summaries. Numbers 1 through 423

International Nuclear Information System (INIS)

1979-09-01

The National Energy Software Center (NESC) serves as the software exchange and information center for the US Department of Energy and the Nuclear Regulatory Commission. A major activity of the Center is the preparation and publication of two reports issued periodically - the Center's compilation of program abstracts, ANL-7411, and this software summaries report, ANL-8040. The abstracts describe the softward packages available in the software exchange library maintained and distributed by the Center. The summaries describe agency-sponsored software that is at the specification stage, under development, being checked out, in use, or available at agency offices, laboratories, and contractor installations. Summaries describe software that is not included in the NESC library due to its preliminary status or because it is believed to be of limited interest. The purpose of the summaries report is to keep agency and contractor personnel informed as to the existence, status, and availability of computer programs within the agency, and thereby minimize duplication costs and maximize the value of agency software development efforts

Measurement Differences Between Two Immunoassay Systems for LH and FSH: A Comparison of Roche Cobas e601 vs. Abbott Architect i2000sr.

Science.gov (United States)

Yin, Lianli; Tang, Yinghua; Chen, Xiang; Sun, Yifan

2018-03-01

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) regulate the growth and reproductive activity of gonadal tissue and determine the concentration of LH is essential for the prediction of ovulation. Collectively, FSH and LH are important measurements to ascertain the causes of infertility as well as diagnosing disorders such as polycystic ovary syndrome and pituitary and gonadal dysfunction. This study compares the correlation between LH and FSH measurements during examination with two different systems, Architect i2000sr (Abbott Laboratories; Lake Bluff, IL, USA) and Cobas e601 (Roche; Geneva, Switzerland), and assesses the differences between these systems. Serum analysis was performed for 95 patients using both the Cobas e601 and Architect i2000sr systems. The method used to compare the systems was Passing-Bablok regression analysis with a Bland-Altman agreement plot. Inter-rater agreement was analyzed using a concordance correlation coefficient. Architect i2000sr and Cobas e601 have strong correlations in their LH and FSH results. However, the Bland-Altman plot shows that LH and FSH measurements in Cobas e601 are about 1.31 times and 1.26 times higher than those in Architect i2000sr, respectively. Passing-Bablok regression analysis also shows significant proportional deviation between them. The difference between the test results for LH and FSH in Cobas e601 and Architect i2000sr indicate that the results from one system cannot be directly used to evaluate the other system.

Multiplex PCR assays offer highly sensitive and specific tools for the detection of enteric pathogens. This prospective study aimed at comparing the novel Roche LightMix Modular Assay Gastro Parasites (LMAGP) detecting Giardia duodenalis, Entamoeba histolytica, Cryptosporidium spp., Blastocystishominis, and Dientamoebafragilis with routine laboratory procedures. Stool specimens (n = 1062 from 1009 patients) were consecutively examined by LMAGP, R-Biopharm Ridascreen enzyme immunoassays (EIAs) detecting G. duodenalis or E. histolytica/dispar, and microscopy of wet mounts. Discrepant results were analysed by in-house PCR. D. fragilis or B. hominis were detected by LMAGP in 131 (14.4%) and 179 (19.9%; 16 samples positive by microscopy; p PCR). G. duodenalis was detected by LMAGP, EIA, or microscopy in 20, 16, or 9 of 1039 stool samples, respectively; all four samples missed by EIA were confirmed by in-house PCR. In total, 938 stool samples were analysed for E. histolytica/dispar. Nine of ten EIA-positive samples were negative by LMAGP but positive by in-house PCR for E. dispar. One E. histolytica infection (positive by both LMAGP and in-house PCR) was missed by EIA and microscopy. Parasites only detected by microscopy included Enterobius vermicularis eggs (n = 3) and apathogenic amoebae (n = 27). The data call for routine use of multiplex PCR assays for the detection of enteric protozoan parasites in laboratory diagnostics.

Barnes, T.

2000-01-01

This short contribution is a late MESON2000 conference summary. As appropriate for the 600th anniversary of the Jagiellonian University, it begins with a brief summary of the last 600 years of European history and its place in hadron physics. Next a ''physicist chirality'' order parameter PC is introduced. When applied to MESON2000 plenary speakers this order parameter illustrates the separation of hadron physicists into disjoint communities. The individual plenary talks in MESON2000 are next sorted according to the subconference associated with each of the 36 plenary speakers. Finally, I conclude with a previously unreported Feynman story regarding the use of models in hadron physics. (author)

2005-04-01

Pooling urogenital specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae by nucleic acid amplification tests is an attractive alternative to individual testing. As pooling can reduce the costs of testing as well as labor, it has been advocated for use in resource-poor settings. However, it has neither been widely adopted nor evaluated for use in developing countries. We evaluated the practical use of pooling first-catch urine (FCU) specimens for the detection of C. trachomatis and N. gonorrhoeae from 690 men in Mumbai, India, by PCR. FCU, urethral smears, and swabs were collected from men seen at two sexually transmitted infection (STI) clinics. All laboratory testing was done at the Lokmanya Tilak General Hospital. Gram stain smears and culture isolation for N. gonorrhoeae were performed. Each FCU was tested individually and in pools using the Roche Amplicor PCR for C. trachomatis and N. gonorrhoeae with an internal control for inhibition. Specimen pools consisted of aliquots from five consecutively processed FCUs combined into an amplification tube. An optical density reading of > or =0.20 indicated a pool for which subsequent testing of individual samples was required. Prevalence by PCR on single specimens was 2.2% (15/690) for C. trachomatis and 5.4% (37/690) for N. gonorrhoeae. Compared to individual FCU results, pooling for C. trachomatis and N. gonorrhoeae had an overall sensitivity of 96.1% (50/52). Specificity was 96.5% (83/86) in that three pools required single testing that failed to identify a positive specimen. Pooling missed two positive specimens, decreased the inhibition rate, and saved 50.3% of reagent costs. In this resource-limited setting, the use of pooling to detect C. trachomatis and N. gonorrhoeae by PCR proved to be a simple, accurate, and cost-effective procedure compared to individual testing.

2010-01-01

Full Text Available Purpose: To determine the prevalence of Chlamydia trachomatis infection in a high-risk population by direct and indirect methods and to evaluate the diagnosis of secretory immunoglobulin A (sIgA. Patients and Methods: Urethral or endocervical specimens from 78 patients (48 females and 30 males were examined by cell culture, direct fluorescence assay, PCR Cobas Amplicor (Roche Molecular Diagnostics, and sIgA was detected by the recombinant lipopolysaccharide (LPS-enzyme-linked immunoassay (rELISA. Serum from each patient was also obtained and analysed for the presence of IgG and IgA antibody by in-house microimmunofluorescence (MIF and by the rELISA method (Medac, Hamburg, Germany. Results: The overall C. trachomatis prevalence determined by direct methods was 28%. The detection of sIgA antibodies was significantly higher in the group of patients with a positive direct detection (50% than in the group of negative direct detection (10.7%. The Chlamydia-specific IgA antibodies were detected by the rELISA in 40.9 and 53.6% of group I (positive direct detection and group II patients (negative direct detection, respectively. The species-specific IgA antibodies were detected by the MIF method in 18.2 and 16.1% of group I and II patients, respectively. Chlamydia genus-specific IgG antibodies were detected by the rELISA in 86.4 and 83.9% of group I and group II patients and, C. trachomatis specific IgG were present in 81.8 and 73.2% of group I and group II patients, respectively, as assessed by the MIF test. Conclusion: Combining the positive direct methods and/or positive sIgA antibody results from cervical or urethral specimens had an indication of current C. trachomatis infection.

Chlamydia trachomatis infection and sexual behaviour among female students attending higher education in the Republic of Ireland.

LENUS (Irish Health Repository)

O'Connell, Emer

2009-10-29

BACKGROUND: There are no prevalence data on Chlamydia trachomatis relating to female students attending higher education available for the Republic of Ireland. This information is required to guide on the necessity for Chlamydia screening programmes in higher education settings. This research aimed to determine the prevalence of and predictive risk factors for Chlamydia trachomatis genital infection among female higher education students in Ireland. METHODS: All females presenting during one-day periods at Student Health Units in three higher education institutions in two cities in the Republic of Ireland were invited to participate. Participants completed a questionnaire on lifestyle and socio-demographic factors and provided a urine sample. Samples were tested for C. trachomatis DNA by a PCR based technique (Cobas Amplicor, Roche). To examine possible associations between a positive test and demographic and lifestyle risk factors, a univariate analysis was performed. All associations with a p value < 0.05 were included in a multivariate logistic regression analysis. RESULTS: Of the 460 sexually active participants 22 tested positive (prevalence 4.8%; 95% CI 3.0 to 7.1%). Variables associated with significantly increased risk were current suggestive symptoms, two or more one-night stands and three or more lifetime sexual partners. The students displayed high-risk sexual behaviour. CONCLUSION: The prevalence of C. trachomatis infection and the lack of awareness of the significance of suggestive symptoms among sexually experienced female students demonstrate the need for a programme to test asymptomatic or non-presenting higher education students. The risk factors identified by multivariate analysis may be useful in identifying those who are most likely to benefit from screening. Alcohol abuse, condom use, sexual behaviour (at home and abroad) and, knowledge of sexually transmitted infections (STIs) (including asymptomatic nature or relevant symptoms) were

Full Text Available Introduction: Hepatitis C virus (HCV infection is diagnosed by the presence of antibodies and is supplemented by confirmatory testing methods, such as recombinant immunoblot assay (RIBA and HCV-RNA detection. This study aimed to evaluate the efficacy of RIBA testing to diagnose HCV infection in blood donors positive for anti-HCV antibodies. Methods: A total of 102 subjects positive for anti-HCV determined by enzyme-linked immunosorbent assay (ELISA at the Hematology and Hemotherapy Foundation of Bahia (HEMOBA were later assessed with new samples using the Abbott Architect anti-HCV test (Abbott Diagnostics, Wiesbaden, Germany, the RIBA III test (Chiron RIBA HCV 3.0 SIA, Chiron Corp., Emeryville, CA, USA, the polymerase chain reaction (PCR; COBAS® AMPLICOR HCV Roche Diagnostics Corp., Indianapolis, IN, USA and line probe assay (LiPA - Siemens, Tarrytown, NY, USA genotyping for HCV diagnosis. Results: Of these new samples, 38.2% (39/102 were positive, 57.8% (59/102 were negative and 3.9% (4/102 were indeterminate for anti-HCV; HCV-RNA was detected in 22.5% (23/102 of the samples. RIBA results were positive in 58.1% (25/43, negative in 9.3% (4/43 and indeterminate in 32.6% (14/43 of the samples. The prevailing genotypes were 1 (78.3%, 18/23, 3 (17.4%, 4/23 and 2 (4.3%, 1/23. All 14 samples with indeterminate RIBA results had undetectable viral loads (detection limit ≤50 IU/mL. Of these samples, 71.4% (10/14 were reevaluated six months later. Eighty percent (8/10 of these samples remained indeterminate by RIBA, and 20% (2/10 were negative. Conclusions: In this study, individuals with indeterminate RIBA results had no detectable HCV-RNA.

Hepatitis B virus (HBV) nucleic acid amplification testing (NAAT) is important for the diagnosis and management of HBV infection. We evaluated the analytical performance of the cobas HBV NAAT (Roche Diagnostics GmbH, Mannheim, Germany) on the cobas 4800 System in comparison with COBAS AmpliPrep/COBAS TaqMan HBV Test (CAP/CTM HBV). Precision was evaluated using three levels of cobas HBV/HCV/HIV-1 Control Kit, and linearity was evaluated across the anticipated measuring range (10.0-1.0×109 IU/mL) at seven levels using clinical samples. Detection capability, including limit of blank (LOB), limit of detection (LOD) and limit of quantitation (LOQ), was verified using the 4th WHO International Standard for HBV DNA for NAT (NIBSC code: 10/266). Correlation between the two systems was compared using 205 clinical samples (102 sera and 103 EDTA plasma). Repeatability and total imprecision (coefficient of variation) ranged from 0.5% to 3.8% and from 0.5% to 3.5%, respectively. Linearity (coefficient of determination, R2) was 0.999. LOB, LOD and LOQ were all acceptable within the observed proportion rate (85%). Correlation was very high between the two systems in both serum and plasma samples (correlation coefficient [r]=0.995). The new cobas HBV real-time PCR assay on the cobas 4800 System showed reliable analytical performances.

Full Text Available The research compared students’ summary writing ability before and after they were taught through blog, a new medium or tool for written communication and interaction in many different languages around the world. The research design is a kind of one group pretest posttest. Participants were 33 first-year students who studied EN 011 course (English in Action in the first semester of the academic year 2012 at Bangkok University. They were divided into six groups. Five or six students in each group created a blog; www.blogger.com, and they worked together for fourteen weeks to produce six pieces of summary written work. Each member in the group worked through providing comments, editing and revising on the blog until the group got a final summary paper and submitted that to the teacher for grading. The instruments used in this study were (1 two summary writing tests (2 a questionnaire surveying students’ attitude toward learning through blogs, and (3 postings on blogs to reflect their learning experience. The results revealed that after the students worked together on weblogs, their English summary writing mean score of the posttest was higher than that of the pretest, and they had positive attitudes towards using weblogs in learning. Regarding cooperative learning experiences through using weblogs, most students thought that it was interesting, a new experience to work with their friends on the weblogs.

Physics through the 1990s: A summary

International Nuclear Information System (INIS)

1986-01-01

This summary presents some highlights of the recently released physics survey Physics Through the 1990s. The purpose of the survey is to provide an authoritative research assessment of the major fields of physics. To accomplish that, the Physics Survey Committee prepared six volumes on the fields of physics and two cross-cutting volumes - Scientific interfaces and Technological Applications and An Overview. This brief summary can do little more than pique the reader's interest in the more complete treatment in those eight volumes, which provide convincing documentation of a physics enterprise that is vital and productive. The summary is organized into three parts. The first part sketches the progress that has occurred over the past decade and gives an indication of where the field is headed. Only a few highlights have been included; in each field of physics, important elements have been omitted for the sake of brevity. The second part relates physics to other sciences and the needs of society. The first two sections are quite selective; applications have received strong emphasis as a principal theme of this summary. The third part indicates some of the requirements for maintaining excellence in physics and includes a brief synopsis of the major recommendations of the Physics Survey Committee

Full Text Available The main features of wave propagation in gyrotropic media are compared with wave propagation in anisotropic media. The results of numerical modelling are presented for three typical seismic exploration models. The first two models are azimuthally anisotropic media (of orthorombic symmetry system, group 2m without and with gyration. The third model is a gyrotropic transversely isotropic medium with a vertical symmetry axis. The computations have been made for propagation of shear waves along the vertical symmetry axis. For sufficiently short wave paths (in our models less than 400 m the two-component (x, y seismograms are similar for all three models. For longer paths both signal shape and signal duration for the first and the third model differ noticeably. Some evidence (experimental data and a micromodel is given to show that the gyrotropy of rocks does exist or, at least, can exist. Les principales caractéristiques de la propagation des ondes dans les milieux gyrotropes sont comparées avec la propagation des ondes dans les milieux azimutalement anisotropes. Les résultats d'une modélisation numérique sont présentés pour trois modèles caractéristiques d'exploration sismique. Les deux premiers modèles sont des milieux anisotropes (de symétrie orthorhombique, groupe 2m avec et sans gyrotropie. Le troisième modèle est un milieu gyrotrope transverse isotrope avec un axe de symétrie vertical. Ces calculs ont été réalisés pour la propagation des ondes transversales le long de l'axe de symétrie vertical. Pour des trajets sismiques suffisamment courts (pour nos modèles, moins de 400 m, les sismogrammes à deux composantes (x, y sont similaires pour les trois modèles. Pour des trajets plus longs, la forme et la durée du signal diffèrent sensiblement pour les modèles 1 et 3. Ceci a pour but de montrer (à l'aide des données expérimentales et d'un micromodèle que la gyrotropie dans les roches existe, ou, tout au moins, peut

1992-09-01

Now the summary report of activities under visiting research program in the Research Reactor Institute, Kyoto University, in fiscal year 1991 has been put in order and published. As compared with the past reports, in the report of this year, pages increased and the style changed, but this is due to the change of the method of adopting researches to that throughout one year from fiscal year 1991. So far one page was allotted to every subject, but this limit was relaxed according to the contents. This style is not yet fixed. As well known, discussion is going on about the way the research reactor and the Research Reactor Institute should be. As for this summary report, in order to receive the international evaluation, it was decided to publish the report in English from fiscal year 1992, and the Progress Report on the research by the Institute personnel is included in it. In this report, 98 summaries of the researches using the KUR and 15 summaries of the researches using the KUCA are collected. One summary which was not reported in fiscal year 1990 is added. (K.I.)

Demaree, Dedra; Allie, Saalih; Low, Michael; Taylor, Julian

2008-10-01

The majority of "special access" students at the University of Cape Town are second language English speakers for whom reading the physics textbook is daunting. As a strategy to encourage meaningful engagement with the text, students wrote textbook summaries due the day material was covered in class. The summaries were returned, and they could bring them or re-write them for use during their examinations. A framework was developed to analyze the summaries based on Waywood, defining three cognitive levels seen in mathematics journaling: recounting, summarizing, and dialoging. This framework was refined, expanded, and tested. Interviews with students were conducted for their views on summary writing and survey questions were included on their final exams. The study was carried out in the 2007 spring semester of the "Foundation Physics Course," a component of the special access program.

2015-10-01

To calculate three summary scores of the Framingham Heart Study neuropsychological battery and determine which score best differentiates between subjects classified as having normal cognition, test-based impaired learning and memory, test-based multidomain impairment, and dementia. The final sample included 2,503 participants. Three summary scores were assessed: (a) composite score that provided equal weight to each subtest, (b) composite score that provided equal weight to each cognitive domain assessed by the neuropsychological battery, and (c) abbreviated score comprised of subtests for learning and memory. Receiver operating characteristic analysis was used to determine which summary score best differentiated between the four cognitive states. The summary score that provided equal weight to each subtest best differentiated between the four cognitive states. A summary score that provides equal weight to each subtest is an efficient way to utilize all of the cognitive data collected by a neuropsychological battery. © The Author(s) 2015.

Generation of Natural-Language Textual Summaries from Longitudinal Clinical Records.

Science.gov (United States)

Goldstein, Ayelet; Shahar, Yuval

2015-01-01

Physicians are required to interpret, abstract and present in free-text large amounts of clinical data in their daily tasks. This is especially true for chronic-disease domains, but holds also in other clinical domains. We have recently developed a prototype system, CliniText, which, given a time-oriented clinical database, and appropriate formal abstraction and summarization knowledge, combines the computational mechanisms of knowledge-based temporal data abstraction, textual summarization, abduction, and natural-language generation techniques, to generate an intelligent textual summary of longitudinal clinical data. We demonstrate our methodology, and the feasibility of providing a free-text summary of longitudinal electronic patient records, by generating summaries in two very different domains - Diabetes Management and Cardiothoracic surgery. In particular, we explain the process of generating a discharge summary of a patient who had undergone a Coronary Artery Bypass Graft operation, and a brief summary of the treatment of a diabetes patient for five years.

The Development and Evaluation of a Novel Instrument Assessing Residents' Discharge Summaries.

Science.gov (United States)

Hommos, Musab S; Kuperman, Ethan F; Kamath, Aparna; Kreiter, Clarence D

2017-04-01

To develop and determine the reliability of a novel measurement instrument assessing the quality of residents' discharge summaries. In 2014, the authors created a discharge summary evaluation instrument based on consensus recommendations from national regulatory bodies and input from primary care providers at their institution. After a brief pilot, they used the instrument to evaluate discharge summaries written by first-year internal medicine residents (n = 24) at a single U.S. teaching hospital during the 2013-2014 academic year. They conducted a generalizability study to determine the reliability of the instrument and a series of decision studies to determine the number of discharge summaries and raters needed to achieve a reliable evaluation score. The generalizability study demonstrated that 37% of the variance reflected residents' ability to generate an adequate discharge summary (true score variance). The decision studies estimated that the mean score from six discharge summary reviews completed by a unique rater for each review would yield a reliability coefficient of 0.75. Because of high interrater reliability, multiple raters per discharge summary would not significantly enhance the reliability of the mean rating. This evaluation instrument reliably measured residents' performance writing discharge summaries. A single rating of six discharge summaries can achieve a reliable mean evaluation score. Using this instrument is feasible even for programs with a limited number of inpatient encounters and a small pool of faculty preceptors.

2000-10-01

Fluidized-bed calcination at the Idaho Nuclear Technologies and Engineering Center (INTEC, formally called the Idaho Chemical Processing Plant) has been used to solidify acidic metal nitrate fuel reprocessing and incidental wastes wastes since 1961. A summary of waste calcination in full-scale and pilot plant calciners has been compiled for future reference. It contains feed compositions and operating conditions for all the processing campaigns for the original Waste Calcining Facility (WCF), the New Waste Calcining Facility (NWCF) started up in 1982, and numerous small scale pilot plant tests for various feed types. This summary provides a historical record of calcination at INTEC, and will be useful for evaluating calcinability of future wastes.

Facilitating the Information Exchange Using a Modular Electronic Discharge Summary.

Denecke, Kerstin; Dittli, Pascal A; Kanagarasa, Niveadha; Nüssli, Stephan

2018-01-01

Discharge summaries are a standard communication tool delivering important clinical information from inpatient to ambulatory care. To ensure a high quality, correctness and completeness, the generation process is time consuming. It requires also contributions of multiple persons. This is problematic since the primary care provider needs the information from the discharge summary for continuing the intended treatment. To address this challenge, we developed a concept for exchanging a modular electronic discharge summary. Through a literature review and interviews with multiple stakeholders, we analysed existing processes and derived requirements for an improved communication of the discharge summary. In this paper, we suggest a concept of a modular electronic discharge summary that is exchanged through the electronic patient dossier in CDA CH level 2 documents. Until 2020, all Swiss hospitals are obliged to connect to the electronic patient dossier. Our concept allows to access already completed modules of the discharge summary from the primary care side, before the entire report is entirely finalised. The data is automatically merged with the local patient record on the physician side and prepared for data integration into the practice information system. Our concept offers the opportunity not only to improve the information exchange between hospital and primary care, but it also provides a potential use case and demonstrates a benefit of the electronic patient dossier for primary care providers who are so far not obliged to connect to the patient dossier in Switzerland.

Comparison of Brief Summary Formats Through a Health Literacy Lens.

Science.gov (United States)

Sharp, Michele L; Hall, Lori; Eleftherion, Anthony; Simpson, Katherine; Neuhauser, Linda

2018-01-01

Print pharmaceutical advertisements in the United States require inclusion of a brief summary of side effects, warnings, precautions, and contraindications from the labeling. The full package insert, which sponsors have traditionally used to fulfill the brief summary requirement, does not adhere to health literacy best practices, limiting its value to consumers. This study compared the understandability and usability of brief summaries in 3 formats designed to be more consumer friendly. Three brief summary formats were tested: (1) 2-column "Question and Answer"; (2) "Prescription Drug Facts Box," similar to current US over-the-counter drug facts labeling; and (3) "Health Literacy," based on clear communication principles. Researchers evaluated the formats using the Suitability Assessment of Materials (SAM) tool and conducted structured, scripted, one-on-one interviews (usability tests) with participants with estimated low to average education levels. This research was replicated across 2 therapeutic areas (type 2 diabetes and plaque psoriasis). SAM scores showed that the Health Literacy format outperformed the Question and Answer format and the Prescription Drug Facts Box format in both therapeutic areas, with both Health Literacy brief summaries rated on the SAM as "superior." Qualitative usability tests supported the SAM findings, with the Health Literacy format preferred consistently over the Question and Answer format, and more often than not over the Prescription Drug Facts Box format. Sponsors can employ a user-tested Health Literacy format to improve the understandability and usability of brief summaries with patients.

2010-01-01

The graphical depiction of uncertainty information is emerging as a problem of great importance. Scientific data sets are not considered complete without indications of error, accuracy, or levels of confidence. The visual portrayal of this information is a challenging task. This work takes inspiration from graphical data analysis to create visual representations that show not only the data value, but also important characteristics of the data including uncertainty. The canonical box plot is reexamined and a new hybrid summary plot is presented that incorporates a collection of descriptive statistics to highlight salient features of the data. Additionally, we present an extension of the summary plot to two dimensional distributions. Finally, a use-case of these new plots is presented, demonstrating their ability to present high-level overviews as well as detailed insight into the salient features of the underlying data distribution. © 2010 The Eurographics Association and Blackwell Publishing Ltd.

Hunter, James; Freer, Yvonne; Gatt, Albert; Reiter, Ehud; Sripada, Somayajulu; Sykes, Cindy; Westwater, Dave

2011-01-01

The BT-Nurse system uses data-to-text technology to automatically generate a natural language nursing shift summary in a neonatal intensive care unit (NICU). The summary is solely based on data held in an electronic patient record system, no additional data-entry is required. BT-Nurse was tested for two months in the Royal Infirmary of Edinburgh NICU. Nurses were asked to rate the understandability, accuracy, and helpfulness of the computer-generated summaries; they were also asked for free-text comments about the summaries. The nurses found the majority of the summaries to be understandable, accurate, and helpful (pgenerated summaries. In conclusion, natural language NICU shift summaries can be automatically generated from an electronic patient record, but our proof-of-concept software needs considerable additional development work before it can be deployed.

An examination of the mechanical effects produced on rocks by an underground nuclear explosion calls for the use of particular means of exploration which are described in this report, special attention being paid to the equipment used in connection with the French nuclear tests in the Sahara. The drilling methods used (rotary and turbo-drilling) are adapted to the particular conditions of the sampling programme, to the radioactivity and to the temperature in the region of the explosion. A study of the samples makes it possible to obtain the new characteristics of the rock and to assess the chemical and mechanical transformations which it has undergone. An examination of the core obtained from the drilling, together with a knowledge of the drilling parameters (depth of the probe, sample recovery, etc...), makes it possible to study the extent and the characteristics of the zones which have been damaged to different degrees according to their distance from the zero point: cavity, strongly powdered zone, fractured zone, chimney, zones containing high stresses leading to a particular type of fracture of the cores. The problems connected with the interpretation of the results are also presented.

Full Text Available In this paper we demonstrate a family of metrics for estimating the quality of a text summary relative to one or more human-generated summaries. The improved metrics are based on features automatically computed from the summaries to measure content and linguistic quality. The features are combined using one of three methods—robust regression, non-negative least squares, or canonical correlation, an eigenvalue method. The new metrics significantly outperform the previous standard for automatic text summarization evaluation, ROUGE.

To investigate and compare the analytical and clinical performance of TianLong automatic hypersensitive hepatitis B virus (HBV) DNA quantification system and Roche CAP/CTM system. Two hundred blood samples for HBV DNA testing, HBV-DNA negative samples and high-titer HBV-DNA mixture samples were collected and prepared. National standard materials for serum HBV and a worldwide HBV DNA panel were employed for performance verification. The analytical performance, such as limit of detection, limit of quantification, accuracy, precision, reproducibility, linearity, genotype coverage and cross-contamination, was determined using the TianLong automatic hypersensitive HBV DNA quantification system (TL system). Correlation and Bland-Altman plot analyses were carried out to compare the clinical performance of the TL system assay and the CAP/CTM system. The detection limit of the TL system was 10 IU/mL, and its limit of quantification was 30 IU/mL. The differences between the expected and tested concentrations of the national standards were less than ± 0.4 Log 10 IU/mL, which showed high accuracy of the system. Results of the precision, reproducibility and linearity tests showed that the multiple test coefficient of variation (CV) of the same sample was less than 5% for 10 2 -10 6 IU/mL; and for 30-10 8 IU/mL, the linear correlation coefficient r 2 = 0.99. The TL system detected HBV DNA (A-H) genotypes and there was no cross-contamination during the "checkerboard" test. When compared with the CAP/CTM assay, the two assays showed 100% consistency in both negative and positive sample results (15 negative samples and 185 positive samples). No statistical differences between the two assays in the HBV DNA quantification values were observed ( P > 0.05). Correlation analysis indicated a significant correlation between the two assays, r 2 = 0.9774. The Bland-Altman plot analysis showed that 98.9% of the positive data were within the 95% acceptable range, and the maximum difference

2006-01-01

In conjunction with its 6. annual meeting, the WPDD in close co-operation with the FSC held a Topical session on 'Stakeholder Involvement in Decommissioning' on November 14, 2005. The session was attended by 36 participants totally representing 14 NEA member countries and 2 international organisations. Two keynote addresses were given at the Topical Session. The first one treated of what is needed for robust decisions and how to bring all stakeholders into the debate. In the second keynote address a summary was made on what have been said on stakeholder involvement in decommissioning during earlier meetings of the WPDD. The main part of the session was then devoted to views from different stakeholders regarding their role and their involvement. This part contained viewpoints from local communities (Kaevlinge in Sweden and Port Hope in Canada), authorities (Scottish Executive and CSNC) and operators (EDF from France and EWN from Germany). Case studies from the decommissioning of Dounrey in the UK and from Trojan and Main Yankee in the USA were presented in the end part of the Topical session followed by a summary and lessons learnt report by the Rapporteur. A detailed programme of the Topical session can be seen in Appendix 1

Full Text Available Roche modified the COBAS AmpliPrep/COBAS TaqMan human immunodeficiency virus type 1 (HIV-1 test version 1.0 (CAP/CTM v1.0, resulting in the COBAS AmpliPrep/COBAS TaqMan HIV-1 test version 2.0 (CAP/CTM v2.0. The aim of this study was to evaluate the performance of the CAP/CTM v2.0 and to compare this performance with that of the CAP/CTM v1.0. The study was conducted in a small local study group in Kaohsiung Medical University Hospital, Kaohsiung, Taiwan. A total of 86 plasma samples from HIV-1-seropositive patients were tested using the two assays. The correlation and concordance of results between the two assays were calculated. The CAP/CTM v2.0 generated higher values than did the CAP/CTM v1.0, and five samples (5.8% yielded a difference of > 1 log10 copies/mL. In addition, our data show that CAP/CTM v1.0 and CAP/CTM v2.0 yielded relatively consistent values for 23 samples with low viral loads (< 200 copies/mL. Furthermore, when viral loads were in a medium range (2–5 log10 copies/mL, the results of the two assays were more compatible. This study shows a good correlation between CAP/CTM v1.0 and v2.0 in HIV-1 viral load measurement. Further attention must be paid to those cases in which measured viral loads present larger differences between the two assays.

The summaries contained in this volume were written by the individual contractors with minimal editing by the Office of Fusion Energy. Previous summaries were published in February of 1982 and December of 1987. The Plasma Theory program is responsible for the development of concepts and models that describe and predict the behavior of a magnetically confined plasma. Emphasis is given to the modelling and understanding of the processes controlling transport of energy and particles in a toroidal plasma and supporting the design of the International Thermonuclear Experimental Reactor (ITER). A tokamak transport initiative was begun in 1989 to improve understanding of how energy and particles are lost from the plasma by mechanisms that transport them across field lines. The Plasma Theory program has actively-participated in this initiative. Recently, increased attention has been given to issues of importance to the proposed Tokamak Physics Experiment (TPX). Particular attention has been paid to containment and thermalization of fast alpha particles produced in a burning fusion plasma as well as control of sawteeth, current drive, impurity control, and design of improved auxiliary heating. In addition, general models of plasma behavior are developed from physics features common to different confinement geometries. This work uses both analytical and numerical techniques. The Fusion Theory program supports research projects at US government laboratories, universities and industrial contractors. Its support of theoretical work at universities contributes to the office of Fusion Energy mission of training scientific manpower for the US Fusion Energy Program.

Plutonium focus area: Technology summary

International Nuclear Information System (INIS)

1996-03-01

To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this approach, EM developed a management structure and principles that led to creation of specific focus areas. These organizations were designed to focus scientific and technical talent throughout DOE and the national scientific community on major environmental restoration and waste management problems facing DOE. The focus area approach provides the framework for inter-site cooperation and leveraging of resources on common problems. After the original establishment of five major focus areas within the Office of Technology Development (EM-50), the Nuclear Materials Stabilization Task Group (NMSTG, EM-66) followed EM-50's structure and chartered the Plutonium Focus Area (PFA). NMSTG's charter to the PFA, described in detail later in this book, plays a major role in meeting the EM-66 commitments to the Defense Nuclear Facilities Safety Board (DNFSB). The PFA is a new program for FY96 and as such, the primary focus of revision 0 of this Technology Summary is an introduction to the Focus Area; its history, development, and management structure, including summaries of selected technologies being developed. Revision 1 to the Plutonium Focus Area Technology Summary is slated to include details on all technologies being developed, and is currently planned for release in August 1996. The following report outlines the scope and mission of the Office of Environmental Management, EM-60, and EM-66 organizations as related to the PFA organizational structure

The perceptual processing capacity of summary statistics between and within feature dimensions

Science.gov (United States)

Attarha, Mouna; Moore, Cathleen M.

2015-01-01

The simultaneous–sequential method was used to test the processing capacity of statistical summary representations both within and between feature dimensions. Sixteen gratings varied with respect to their size and orientation. In Experiment 1, the gratings were equally divided into four separate smaller sets, one of which with a mean size that was larger or smaller than the other three sets, and one of which with a mean orientation that was tilted more leftward or rightward. The task was to report the mean size and orientation of the oddball sets. This therefore required four summary representations for size and another four for orientation. The sets were presented at the same time in the simultaneous condition or across two temporal frames in the sequential condition. Experiment 1 showed evidence of a sequential advantage, suggesting that the system may be limited with respect to establishing multiple within-feature summaries. Experiment 2 eliminates the possibility that some aspect of the task, other than averaging, was contributing to this observed limitation. In Experiment 3, the same 16 gratings appeared as one large superset, and therefore the task only required one summary representation for size and another one for orientation. Equal simultaneous–sequential performance indicated that between-feature summaries are capacity free. These findings challenge the view that within-feature summaries drive a global sense of visual continuity across areas of the peripheral visual field, and suggest a shift in focus to seeking an understanding of how between-feature summaries in one area of the environment control behavior.

2005-12-01

Full Text Available The volcanics and volcanoclastic rocks of Draa Sfar (Central Jebilet, Moroccan hercynian belt are affected by ductile stress and hydrothermal alteration accompanied by a weak degree of metamorphism (greenschist facies. Some N-S oriented shearing zones, affect locally these formations while being the site of an important hydrothermal activity. The consequences of these transformations from a non to slightly- deformed rhyodacite, show that through these ductile shearing zones: (1 the mineralogical assemblage of hydrothermal alteration is essentially formed by chlorite, sericite, quartz and magnetite; (2 the gradual increase of the alteration indexes is accompanied by the destruction of the phenocrists and the recrystallization of the matrix by phyllosilicates and quartz; (3 the progressive transfer of material is more intense in the more deformed zones where the values of Ti, Al and Zr remain constant. These shearing zones played a very important role in the circulation of fluids and the transformation of the rhyodacite of Draa Sfar.Les roches volcaniques et volcanoclastiques de Draa Sfar (Jebilet centrales, Maroc hercynien sont affectées par une déformation ductile accompagnée d’un métamorphisme de faible degré (faciès schistes verts et d’une altération hydrothermale. Des zones de cisaillement de direction N-S, ont affecté localement ces formations tout en étant vecteurs d’une importante activité hydrothermale. Le suivi de ces transformations à partir de la rhyodacite non ou peu déformée, montre qu’à travers ces zones de cisaillements ductiles : (1 l’assemblage minéralogique d’altération hydrothermale est formé essentiellement de chlorite, de séricite, de quartz et de magnétite ; (2 l’augmentation graduelle des indices d’altération s’exprime par la destruction des phénocristaux au profit d’une matrice recristallisée en phyllosilicates et quartz ; (3 le transfert progressif de la matière est plus intense

2018-01-01

To apply "user testing" to maximize readability and acceptability of a Clinical Trial Results Laypersons Summary-a new European requirement. "User testing" (using questionnaire and semistructured interview) assessed whether people could find and understand key points. Findings were used to improve content and design, prior to retesting. Participants had a range of levels of health literacy and there was a higher education group. Participants accessed the summary on screen. In round 1 we tested 12 points of information. In round 2 a revised summary addressing round 1 findings was tested, leading to a third final version. In round 1, 2 of 12 points of information did not reach the target and interviews raised further format and content issues (some distracting technical explanations and inability to find or understand the 2 main study purposes). These findings informed revisions for the version tested in round 2, with 2 different points not reaching the target (inclusion criteria relating to duration of seasonal allergies and how researchers found out about participants' symptoms). Identified problems in both rounds were addressed and reflected in the final version. Despite improvements, participants did not consistently understand that summaries were intended for the public, or to only interpret results of single trials in the context of additional trials. All readers, including those with higher education, found the clear and straightforward language acceptable. Applying "user testing" resulted in a largely health-literate summary suitable for people across a range of backgrounds.

Laboratory blood analysis in Strigiformes-Part II: plasma biochemistry reference intervals and agreement between the Abaxis Vetscan V2 and the Roche Cobas c501.

Limited plasma biochemical information is available in Strigiformes. Only one study investigated the agreement between a point-of-care with a reference laboratory analyzer for biochemistry variables in birds. The objective was to report reference intervals (RI) for plasma biochemistry variables in Strigiformes, and to assess agreement between the Abaxis Vetscan V2 and Roche Cobas c501. A prospective study was designed to assess plasma biochemistry RI for concentration of calcium, phosphorus, total protein, albumin, globulin, glucose, bilirubin, uric acid, bile acids, sodium, potassium, and chloride, and activities of AST, GGT, CK, amylase, lipase, LDH, and GLDH. In addition, the agreement between the Vetscan and the Cobas in owl species was assessed. A total of 190 individuals were sampled belonging to 12 Strigiformes species including Barn Owls, Barred Owls, Great Horned Owls, Eurasian Eagle Owls, Spectacled Owls, Eastern Screech Owls, Long-Eared Owls, Short-Eared Owls, Great Gray Owls, Snowy Owls, Northern Saw-Whet Owls, and Northern Hawk-Owls. Order-, species-, and method-specific RI were determined on both analyzers. Although Vetscan data were not equivalent to the Cobas, 4 analytes (glucose, AST, CK, and total protein, with correction for bias) were within acceptable agreement, 3 analytes (uric acid, calcium, and phosphorus) were within close agreement, and the remaining analytes were in strong disagreement. Species-specific differences were observed notably for the concentration of glucose in Barn Owls and electrolytes in Northern Saw-Whet Owls. Overall, this study suggests that the Vetscan has acceptable clinical performance in Strigiformes for some analytes and highlights discrepancies for several analytes. © 2015 American Society for Veterinary Clinical Pathology.

High-risk Human Papillomavirus Determination in Formalin-fixed, Paraffin-embedded Cervical Tissue Using the Roche Cobas 4800 System: A Comparative Study With Liquid-based Cytology.

Tardío, Juan C; Cambero, Olivia; Sánchez-Estévez, Carolina; Sánchez-García, Ana B; Angulo, Fernando; Moreno, Amalia

2017-11-14

Roche cobas 4800 human papillomavirus (HPV) test is an automated real-time polymerase chain reaction-based system that allows the simultaneous detection of 14 human papillomavirus high-risk (HR-HPV) genotypes. This test is Food and Drug Administration approved since 2011 for HPV determination in liquid-based cytologic samples, but a clinically validated technique for formalin-fixed, paraffin-embedded (FFPE) tissue specimens is presently not commercially available. In our laboratory, we have developed an HPV detection procedure in FFPE tissue by cobas 4800 HPV test. In order to validate our method, we retrospectively studied 165 FFPE cervical biopsy and conization specimens with varied diagnoses from our files. In 50 of them, we contrasted the results with those obtained from simultaneous liquid-based cytologies from the same patients. Finally, seeking the possible complementary clinical usefulness of the procedure, we compared the HPV genotypes detected in cervical intraepithelial neoplasia grade 1 (CIN1)-diagnosed biopsies from 20 patients with a subsequent high-grade CIN (CIN2+) diagnosis with those from another group of 20 patients without a posterior CIN2+ diagnosis. Eighty-seven percent of the assays provided informative results. HR-HPV was detected in 28 of 32 (88%) invasive cervical squamous carcinomas. Coincidental HR-HPV genotypes were obtained in 32 of 50 (64%) cases with simultaneous cervical biopsy and liquid-based cytologic samples. A significant higher risk of progression to CIN2+ was found when HPV16 (P=0.022) or any HR-HPV genotype (P=0.037) was detected in CIN1 biopsies. The reported procedure provides an automated, technically time-saving, easy to integrate into laboratory routine, and reliable method of HR-HPV determination in FFPE specimens.

Summary statistics for end-point conditioned continuous-time Markov chains

DEFF Research Database (Denmark)

Hobolth, Asger; Jensen, Jens Ledet

Continuous-time Markov chains are a widely used modelling tool. Applications include DNA sequence evolution, ion channel gating behavior and mathematical finance. We consider the problem of calculating properties of summary statistics (e.g. mean time spent in a state, mean number of jumps between...... two states and the distribution of the total number of jumps) for discretely observed continuous time Markov chains. Three alternative methods for calculating properties of summary statistics are described and the pros and cons of the methods are discussed. The methods are based on (i) an eigenvalue...... decomposition of the rate matrix, (ii) the uniformization method, and (iii) integrals of matrix exponentials. In particular we develop a framework that allows for analyses of rather general summary statistics using the uniformization method....

Quinn, Helen R

2002-01-01

This is the summary talk of a meeting held at the KEK, Tsukuba, Japan, November 20-22, 2001. This meeting has been a wonderful testimony to the success of particle physics in Japan. The hosts are involved in all aspects of flavor physics, both with the world-class facilities in this laboratory and elsewhere in this country, and through their participation in experiments elsewhere. The results they have shown these past few days are at the forefront of B physics and neutrino physics, and the plans for the future we have seen are equally impressive. I give a brief summary of the talks we heard, and a few comments of my own on various points that have been made. Other talks given at this meeting are referred to by the speakers last name; these talks will appear in the same proceedings. See these talks for the detailed references for each subject

U.S. Nuclear Power Plant Operating Cost and Experience Summaries

Reid, RL

2003-01-01

The ''U.S. Nuclear Power Plant Operating Cost and Experience Summaries'' (NUREG/CR-6577, Supp. 2) report has been prepared to provide historical operating cost and experience information on U.S. commercial nuclear power plants during 2000-2001. Costs incurred after initial construction are characterized as annual production costs, which represent fuel and plant operating and maintenance expenses, and capital expenditures related to facility additions/modifications, which are included in the plant capital asset base. As discussed in the report, annual data for these two cost categories were obtained from publicly available reports and must be accepted as having different degrees of accuracy and completeness. Treatment of inconclusive and incomplete data is discussed. As an aid to understanding the fluctuations in the cost histories, operations summaries for each nuclear unit are provided. The intent of these summaries is to identify important operating events; refueling, major maintenance, and other significant outages; operating milestones; and significant licensing or enforcement actions. Information used in the summaries is condensed from operating reports submitted by the licensees, the Nuclear Regulatory Commission (NRC) database for enforcement actions, and outage reports

2015-09-01

Comorbidity adjustment is an important component of health services research and clinical prognosis. When adjusting for comorbidities in statistical models, researchers can include comorbidities individually or through the use of summary measures such as the Charlson Comorbidity Index or Elixhauser score. We examined the conditions under which individual versus summary measures are most appropriate. We provide an analytic proof of the utility of comorbidity summary measures when used in place of individual comorbidities. We compared the use of the Charlson and Elixhauser scores versus individual comorbidities in prognostic models using a SEER-Medicare data example. We examined the ability of summary comorbidity measures to adjust for confounding using simulations. We devised a mathematical proof that found that the comorbidity summary measures are appropriate prognostic or adjustment mechanisms in survival analyses. Once one knows the comorbidity score, no other information about the comorbidity variables used to create the score is generally needed. Our data example and simulations largely confirmed this finding. Summary comorbidity measures, such as the Charlson Comorbidity Index and Elixhauser scores, are commonly used for clinical prognosis and comorbidity adjustment. We have provided a theoretical justification that validates the use of such scores under many conditions. Our simulations generally confirm the utility of the summary comorbidity measures as substitutes for use of the individual comorbidity variables in health services research. One caveat is that a summary measure may only be as good as the variables used to create it.

Summary status of K Basins sludge characterization

International Nuclear Information System (INIS)

Baker, R.B.

1995-01-01

A number of activities are underway as part of the Spent Nuclear Fuels Project (SNFP) related to the processing and disposing of sludge in the 105-K Basins (K Basins). Efforts to rigorously define data requirements for these activities are being made using the Data Quality Objectives (DQO) process. Summaries of current sludge characterization data are required to both help support this DQO process and to allow continued progress with on-going engineering activities (e.g., evaluations of disposal alternatives). This document provides the status of K Basins sludge characterization data currently available to the Nuclear Fuel Evaluations group. This group is tasked by the SNFP to help develop and maintain the characterization baseline for the K Basins. The specific objectives of this document are to: (1) provide a current summary (and set of references) of sludge characterization data for use by SNFP initiatives, to avoid unnecessary duplication of effort and to support on-going initiatives; (2) submit these data to an open forum for review and comment, and identify additional sources of significant data that may be available; (3) provide a summary of current data to use as part of the basis to develop requirements for additional sludge characterization data through the DQO process; (4) provide an overview of the intended activities that will be used to develop and maintain the sludge characterization baseline

Étude de la mouillabilité des roches réservoir à l'échelle du pore par cryomicroscopie électronique à balayage Wettability of Reservoir Rock At the Pore Scale: Contribution of Cryo-Scanning Electron Microscopy

Full Text Available Le but de cette étude est de caractériser, à l'échelle du pore, la mouillabilité des roches réservoir, en relation avec leur géométrie et/ou leur minéralogie. Cette caractérisation se fait, après congélation des échantillons, par l'observation de la distribution des fluides au sein du milieu poreux (saumure et huile brute, en microscopie électronique à balayage. Les expériences ont d'abord été effectuées sur des roches modèles parfaitement mouillables à l'eau, verre fritté et grès naturels. Certains de ces minéraux ont été rendus hydrophobes par greffage de silane. L'étude de ces systèmes a mis en évidence une corrélation entre la mouillabilité et la distribution des fluides. Puis, une roche réservoir (grès argileux de la formation de Brent, de mer du Nord connue comme étant de mouillabilité intermédiaire a été étudiée. Un travail précédent (étude de déplacements eau/huile par tomographie X avait abouti à la conclusion que si ces roches présentaient des hétérogénéités de mouillabilité, l'échelle de ces hétérogénéités devait être inférieure au millimètre. Les études de cryomicroscopie ont montré le caractère hydrophobe de la kaolinite, tandis que les illites, le quartz et les feldspaths sont préférentiellement mouillables à l'eau. L'imbibition spontanée d'huile pourrait ainsi être attribuée à l'existence au sein de la roche d'un réseau de kaolinite, tandis que l'imbibition spontanée de saumure serait due à l'existence d'un second réseau plus ou moins imbriqué avec le premier et constitué des autres minéraux. Un autre cas de roche réservoir a été étudié, à savoir un carbonate du Moyen-Orient. Les mésopores intergranulaires y ont été observés comme étant mouillables à l'huile tandis que les micropores restaient mouillables à l'eau. Dans ce cas, la mouillabilité intermédiaire de ces échantillons s'explique par la géométrie plutôt que par la min

Behavioral and social changes in the modern era have triggered an increase in the incidence of early sexual contact and teenage pregnancy. Since there is no routine Gonococcal & Chlamydial (GC & CT) screening in teens in antenatal clinics in Thailand, the present study was performed to find the prevalence of STI, especially Chlamydial infection, in teenage pregnancy. To evaluate the prevalence of sexually transmitted infections (STIs), especially Chlamydial infection (CT), in teenage pregnancy and its related factors. One hundred and twenty-one teenage pregnancies were recruited at the ANC in Rajavithi Hospital from October 2006 to May 2007. After signing informed consent forms, they were asked to answer questionnaires about baseline data, sexual information and risk factors, after which urine specimens were collected for screening for GC and CT using the PCR technique (AMPLICOR by Roche). Later, pelvic examination was per formed by the gynecologist at the STD (sexually transmitted disease) clinic. All the data and LAB results were recorded and analyzed by the SPSS program. Numbers, percentages, means with SD, Chi-squared test, Fisher's exact test and odds ratio were used. Potential risk factors were analyzed using binary logistic regression. The prevalence of STI in pregnant teenagers was 28.1% (CT = 19.8%, GC = 1.7%, hepatitis B = 3.3%, trichomoniasis 1.7%, Herpes simplex = 0.8% and condyloma acuminata = 0.8%). No Syphilis, chancroid or HIV were found in the present study Other non-STI like candidiasis and bacterial vaginosis were found in 45.5% of participants (candidiasis and bacterial vaginosis at 19.0% and 24.8%, respectively). The risk of CT infection was significantly related (6.9 times higher) to having previous sexual contact before the current partner (95% CI, 1.8-27.0). STI, especially Chlamydial infection, was found in a significant number of teenage pregnancies. Measures should be taken to prevent this resulting in complicated outcomes in the future.

Survival of infants born to HIV-positive mothers, by feeding modality, in Rakai, Uganda.

Full Text Available BACKGROUND: Data comparing survival of formula-fed to breast-fed infants in programmatic settings are limited. We compared mortality and HIV-free of breast and formula-fed infants born to HIV-positive mothers in a program in rural, Rakai District Uganda. METHODOLOGY/PRINCIPAL FINDINGS: One hundred eighty two infants born to HIV-positive mothers were followed at one, six and twelve months postpartum. Mothers were given infant-feeding counseling and allowed to make informed choices as to whether to formula-feed or breast-feed. Eligible mothers and infants received antiretroviral therapy (ART if indicated. Mothers and their newborns received prophylaxis for prevention of mother-to-child HIV transmission (pMTCT if they were not receiving ART. Infant HIV infection was detected by PCR (Roche Amplicor 1.5 during the follow-up visits. Kaplan Meier time-to-event methods were used to compare mortality and HIV-free survival. The adjusted hazard ratio (Adjusted HR of infant HIV-free survival was estimated by Cox regression. Seventy-five infants (41% were formula-fed while 107 (59% were breast-fed. Exclusive breast-feeding was practiced by only 25% of breast-feeding women at one month postpartum. The cumulative 12-month probability of infant mortality was 18% (95% CI = 11%-29% among the formula-fed compared to 3% (95% CI = 1%-9% among the breast-fed infants (unadjusted hazard ratio (HR = 6.1(95% CI = 1.7-21.4, P-value < 0.01. There were no statistically significant differentials in HIV-free survival by feeding choice (86% in the formula-fed compared to 96% in breast-fed group (Adjusted RH = 2.8[95%CI = 0.67-11.7, P-value = 0.16] CONCLUSIONS/SIGNIFICANCE: Formula-feeding was associated with a higher risk of infant mortality than breastfeeding in this rural population. Our findings suggest that formula-feeding should be discouraged in similar African settings.

Improving the accuracy of operation coding in surgical discharge summaries

Science.gov (United States)

Martinou, Eirini; Shouls, Genevieve; Betambeau, Nadine

2014-01-01

Procedural coding in surgical discharge summaries is extremely important; as well as communicating to healthcare staff which procedures have been performed, it also provides information that is used by the hospital's coding department. The OPCS code (Office of Population, Censuses and Surveys Classification of Surgical Operations and Procedures) is used to generate the tariff that allows the hospital to be reimbursed for the procedure. We felt that the OPCS coding on discharge summaries was often incorrect within our breast and endocrine surgery department. A baseline measurement over two months demonstrated that 32% of operations had been incorrectly coded, resulting in an incorrect tariff being applied and an estimated loss to the Trust of £17,000. We developed a simple but specific OPCS coding table in collaboration with the clinical coding team and breast surgeons that summarised all operations performed within our department. This table was disseminated across the team, specifically to the junior doctors who most frequently complete the discharge summaries. Re-audit showed 100% of operations were accurately coded, demonstrating the effectiveness of the coding table. We suggest that specifically designed coding tables be introduced across each surgical department to ensure accurate OPCS codes are used to produce better quality surgical discharge summaries and to ensure correct reimbursement to the Trust.

The summaries were derived from presentations, interviews and discussions at the conference. The summaries are given at two levels, overall for the conference and for specific sessions as follows: 1) Overall Conference: 'A Sound Scientific Basis for Serious Decisions; 2) Sessions on EC Policy and Socio-Political Issues: 'Promoting Safety and Protecting Society'; 3) Session on P and T: 'Partitioning and Transmutation: A Technical Fix or Technical Training?'; 4) Sessions on Geological Disposal and Research Networking: 'No Technical Barriers to Geological Disposal'. First an overall summary of Euradwaste '04 is presented. Significant progress was made on the technical and scientific basis for geological disposal of radioactive waste during the European Commission's Fifth EURATOM Framework Programme for Research (FP5). Deep geological disposal is technically feasible now and can demonstrate the guarantees of long-term isolation and protection of the public. In parallel, socio-political studies have produced methodologies for constructive dialogue with potential host communities that reflect the honesty and openness expected by a democratic society. A harmonized legislative framework for nuclear safety and waste disposal across the enlarged European Union is currently being discussed. Disposal in deep (> 300 metre) geological repositories, the favoured strategy in Europe for long-lived high-level radioactive waste, is now possible. The Sessions on EC Policy and Socio-Political Issues are summarized as follows. The opening day of Euradwaste '04 focused on European Commission policy, including the proposed Directives on disposal of radioactive waste and nuclear safety and socio-political aspects including governance and decision making, public perception/acceptance of waste disposal and its sustainability. A decision on the proposed package will now be made after Union enlargement. Public agreement on the siting of

Patients' electronic medical record contains all information related to treatment processes during hospitalization. One of the most important documents in this record is the record summary. In this document, summary of the whole treatment process is presented which is used for subsequent treatments and other issues pertaining to the treatment. Using suitable architecture for this document, apart from the aforementioned points we can use it in other fields such as data mining or decision making based on the cases. In this study, at first, a model for patient's medical record summary has been suggested using semantic web-based architecture. Then, based on service-oriented architecture and using Java programming language, a software solution was designed and run in a way to generate medical record summary with this structure and at the end, new uses of this structure was explained. in this study a structure for medical record summaries along with corrective points within semantic web has been offered and a software running within Java along with special ontologies are provided. After discussing the project with the experts of medical/health data management and medical informatics as well as clinical experts, it became clear that suggested design for medical record summary apart from covering many issues currently faced in the medical records has also many advantages including its uses in research projects, decision making based on the cases etc.

As most of the heritability of complex traits is attributed to common and low frequency genetic variants, imputing them by combining genotyping chips and large sequenced reference panels is the most cost-effective approach to discover the genetic basis of these traits. Association summary statistics from genome-wide meta-analyses are available for hundreds of traits. Updating these to ever-increasing reference panels is very cumbersome as it requires reimputation of the genetic data, rerunning the association scan, and meta-analysing the results. A much more efficient method is to directly impute the summary statistics, termed as summary statistics imputation, which we improved to accommodate variable sample size across SNVs. Its performance relative to genotype imputation and practical utility has not yet been fully investigated. To this end, we compared the two approaches on real (genotyped and imputed) data from 120K samples from the UK Biobank and show that, genotype imputation boasts a 3- to 5-fold lower root-mean-square error, and better distinguishes true associations from null ones: We observed the largest differences in power for variants with low minor allele frequency and low imputation quality. For fixed false positive rates of 0.001, 0.01, 0.05, using summary statistics imputation yielded a decrease in statistical power by 9, 43 and 35%, respectively. To test its capacity to discover novel associations, we applied summary statistics imputation to the GIANT height meta-analysis summary statistics covering HapMap variants, and identified 34 novel loci, 19 of which replicated using data in the UK Biobank. Additionally, we successfully replicated 55 out of the 111 variants published in an exome chip study. Our study demonstrates that summary statistics imputation is a very efficient and cost-effective way to identify and fine-map trait-associated loci. Moreover, the ability to impute summary statistics is important for follow-up analyses, such as Mendelian

The intramolecular oxidation of ROCH 3 to ROCH 2 OH, where the latter compound spontaneously decomposed to ROH and HCHO, was observed during the reaction of the supramolecular complex (met-hemoCD3) with cumene hydroperoxide in aqueous solution. Met-hemoCD3 is composed of meso-tetrakis(4-sulfonatophenyl)porphinatoiron(III) (Fe III TPPS) and a per-O-methylated β-cyclodextrin dimer having an -OCH 2 PyCH 2 O- linker (Py=pyridine-3,5-diyl). The O=Fe IV TPPS complex was formed by the reaction of met-hemoCD3 with cumene hydroperoxide, and isolated by gel-filtration chromatography. Although the isolated O=Fe IV TPPS complex in the cyclodextrin cage was stable in aqueous solution at 25 °C, it was gradually converted to Fe II TPPS (t 1/2 =7.6 h). This conversion was accompanied by oxidative O-demethylation of an OCH 3 group in the cyclodextrin dimer. The results indicated that hydrogen abstraction by O=Fe IV TPPS from ROCH 3 yields HO-Fe III TPPS and ROCH 2 . . This was followed by radical coupling to afford Fe II TPPS and ROCH 2 OH. The hemiacetal (ROCH 2 OH) immediately decomposed to ROH and HCHO. This study revealed the ability of oxoferryl porphyrin to induce two-electron oxidation. © 2016 Wiley-VCH Verlag GmbH & Co.
