Evaluation of a new rapid lateral flow chromatography test for the diagnosis of Helicobacter pylori.

OBJECTIVE The rapid, simple and non-invasive diagnosis of Helicobacter pylori (H. pylori) infection is important in implementing chemotherapy in appropriate manner, and in assessing persistent H. pylori infection after eradication therapy. The ImmunoCard STAT! HpSA kit (Meridian Bioscience, Europe) is a lateral flow chromatography test which utilizes a monoclonal anti-H. pylori antibody. In this study, we investigated the usefulness of the ImmunoCard STAT! HpSA test before and after eradication therapy on patients referred to undergo upper gastrointestinal endoscopy. METHODS Sixty-five consecutive patients who were referred to undergo upper gastrointestinal endoscopy at the Department of Gastroenterology, Karadeniz Technical University Medical School, Turkey between February and August 2005 were included in this study. The ImmunoCard STAT! HpSA was compared with 4 invasive tests (histology, gram staining, rapid urease test, and culture). The reference method was defined as positive when 2 of the 4 invasive tests were positive. A negative H. pylori status was considered when all 4 tests present concordant negative results. RESULTS Overall, the ImmunoCard STAT! HpSA test had 77.8% sensitivity, 79.3% specificity, 82.4% positive predictive value (PPV) and 74.2% negative predictive value (NPV) in all patients. With regard to pre-treatment values, the sensitivity was 70.6%, specificity 70.6%, PPV 100% and NPV 100% while on post-treatment group the sensitivity was 84.2%, specificity 64.7%, PPV 72.7% and NPV 78.6%. CONCLUSION Our results indicate that the ImmunoCard STAT! HpSA test is a rapid, simple, and helpful procedure not only to determine H. pylori infection but also to assess the success of eradication therapy.
Transforaminal Lumbar Interbody Fusion for the Treatment of Spondylolisthesis and Degenerative Segmental Instability; Surgical and Radiological Outcome

© 2015 Egyptian Journal of Neurosurgery. All rights reserved Background: Transforaminal lumbar interbody fusion (TLIF) was originally described by Harms and Rollinger in the early 1980s as a surgical method of treating symptomatic lumbar disk degeneration. Objective: Evaluation of the clinical and radiological results of the instrumented Transforaminal lumber interbody fusion with single cage for the treatment of spondylolisthesis grade1&2 and in degenerative segmental instability. Patients and Methods: This is a prospective study of thirty patients with lumbar spondylolithesis either isthmic or degenerative, admitted and operated by transforaminal lumbar interbody fusion (TLIF) in the Department of Neurosurgery, Tanta University hospital, from January 2010 to July 2013. Results: In the thirty patients, 66.7% of them were females. Age of the patients ranged between 24-52 years with a mean age of 36 years. History of back trauma could be obtained in 40% of patients and incidence of consanguinity was 10% of patients. Low back pain and sciatica were present in all patients. Neurological deficits included sensory deficits in 40%, reflex changes in 40% and motor in 20% of patients. The affected level was L4-5 in 50%, L5-S1 in 40% and was L3-4 in 10% of patients. Grade I was encountered in 60%, and grade II in 40% of patients. All of the patients had good outcome as regard pain relief. The complications occurred in our study including wound infection in two patients, dural tear in two patients and TLIF cage migration with screw malposition in one patient. Clinical and radiological follow up of the patients was done for a period of 3-6 months. Solid fusion was obtained in 86.7%. Conclusion: The instrumented TLIF with single cage is a safe and effective method for the treatment of spondylolisthesis G I & II and degenerative segmental instability.
Effects of Mismatched Parameters in MRAS Sensorless Doubly Fed Induction Machine Drives

This paper deals with a performance analysis of sensorless drives based on doubly fed induction machines. A simplified model of the whole system equipped with a generic model reference adaptive system (MRAS) observer is introduced, by taking also into account a mismatch in the parameters. Three MRAS known in literature are analyzed in detail and meaningful analytic relations between the mismatched parameters and the error in the estimated rotor position during a steady-state operation are deduced. Then, a stability analysis is performed and the stability regions of each drive are found. Finally, the theoretical results are experimentally validated.
Preliminary results of narrowband Doppler radar imaging using real data in the 0.5 THz frequency band

In this paper preliminary results of radar imaging measurements using a narrowband signal in the low terahertz band are presented. Measurement system architecture as well as the narrowband imaging technique are also discussed. Verification of the theoretical method of acquiring images by the use of narrowband signal through its application to real radar data is presented. Additionally, the results obtained are compared with the results acquired using the Inverse Synthetic Aperture Radar (ISAR) technique utilizing a bandlimited signal.
Effects of the interannual variations in the flood pulse mediated by hypoxia tolerance: the case of the fish assemblages in the upper Parana River floodplain

The effects of the duration of the floods on abiotic variables and attributes of species tolerant and intolerant to hypoxia (STH and SIH respectively) were evaluated in rivers and lakes of the upper Parana River. Fish were sampled once a year, in six sampling stations, during the high water period from 2000 to 2003. There were overall reductions in dissolved oxygen levels and increases in transparency of water in lakes in years of moderate floods. The duration of floods influenced species differentially based on their tolerance to hypoxia: in moderate floods, richness of STH increased and numerical abundance and biomass of SIH reduced significantly. Opposite relationships were detected between dissolved oxygen and the attributes of STH and SIH. Dissolved oxygen was the best predictor of variability of STH and SIH in years of moderate floods, whereas water transparency predicted significant amounts of STH in years of short floods. Being positively affected by dissolved oxygen reductions, STH seem to take advantages in persisting in seasonally harsh lentic habitats. The incorporation of abiotic data as well the differential tolerance of species to hypoxia would improve further investigations of the effects of interannual variations in the flood pulse on tropical fish assemblages
Gestion dynamique des topologies sans fils

La problematique de la qualite de service dans les reseaux locaux sans fils IEEE 802.11 demeure l'un des defis delicats a surmonter par la communaute scientifique. L'etude et l'evaluation des approches apportes pour le support de QoS dans ce type de reseaux que ce soit par des simulations, des modeles analytiques ou des mesures reelles montrent que ces approches sont toujours insuffisantes pour apporter des vraies garanties de qualite de services aux utilisateurs sans fils. Suite a des travaux effectues au CRAN qui ont porte sur l'equilibrage des charges dans les reseaux Ethernet industriels nous avons opte pour une methode d'equilibrage de charges dans le contexte des reseaux Hotspots 802.11. L'objectif de cette approche est d'equilibrer les charges des points d'acces pour satisfaire aux besoins en termes de qualite de service de l'ensemble des applications sans fils. Ces besoins sont exprimes en termes de disponibilite, de delais, de bande passante, etc. Nous avons alors definis un algorithme d'equilibrage de charges pouvant etablir dynamiquement des associations optimales entre les utilisateurs presents dans un Hotspot et les points d'acces en service. Un protocole d'echanges entre les stations sans fils et les points d'acces et entre ces derniers et le serveur d'equilibrage de charges a ete etabli. Le fonctionnement de ce protocole a ete verifie et simule en utilisant les outils SDL et MSC. Pour l'evaluation de la performance de l'approche d'equilibrage par rapport a la methode d'acces de base du protocole, nous avons effectue une ensemble de simulations sur OPNET et montre que cette approche permet d'ameliorer un ensemble de parametres de qualite de service percu par les utilisateurs d'un reseau Hotspot. Dans le futur, nous continuerons a travailler sur l'evaluation de cette approche couplee avec les nouvelles recommandations du standard IEEE 802.11e et a trouver les solutions techniques necessaires a son implementation.
Control and Coordination of Head, Eyes, and Facial Expressions of Virtual Actors in Virtual Environments

This paper addresses the modeling and computational issues associated with the control and coordination of head, eyes, and facial expressions of virtual human actors. The emphasis, as much as possible, is on using accurate physics-based computations for motion computation. Some key issues discussed in this work include the use of kinematics and inverse kinematics, trajectory planning, and the use of finite element methods to model soft tissue deformations.
Molecular Mechanisms of Sexual Development

Gonadal cellular organization is very similar in all vertebrates, though different processes can trigger bipotential gonads to develop into either testes or ovaries. While mammals and birds, apart from some exceptions, show genetic sex determination (GSD), other animals, like turtles and crocodiles, express temperature-dependent sex determination. In some groups of animals, GSD can also be overridden by hormone or temperature influences, indicating how fragile this system can be. This review aims to explain the fundamental molecular mechanisms involved in mammalian GSD, mainly referring to mouse as a major model. Conceivably, other mammals might show a molecular mechanism different from the commonly investigated murine species.
Solution structure of an A-tract DNA bend.

The solution structure of a DNA dodecamer d(GGCAAAAAACGG)/d(CCGTTTTTTGCC) containing an A-tract has been determined by NMR spectroscopy with residual dipolar couplings. The structure shows an overall helix axis bend of 19 degrees in a geometry consistent with solution and gel electrophoresis experiments. Fourteen degrees of the bending occurs in the GC regions flanking the A-tract. The remaining 5 degrees is spread evenly over its six AT base-pairs. The A-tract is characterized by decreasing minor groove width from the 5' to the 3' direction along the A strand. This is a result of propeller twist in the AT pairs and the increasing negative inclination of the adenine bases at the 3' side of the run of adenine bases. The four central thymine bases all have negative inclination throughout the A-tract with an average value of -6.1 degrees. Although this negative inclination makes the geometry of the A-tract different from all X-ray structures, the proton on N6 of adenine and the O4 of thymine one step down the helix are within distance to form bifurcated hydrogen bonds. The 5' bend of 4 degrees occurs at the junction between the GC flank and the A-tract through a combination of tilt and roll. The larger 3' bend, 10 degrees, occurs in two base steps: the first composed of tilt, -4.1 degrees, and the second a combination of tilt, -4.2 degrees, and roll, 6.0 degrees. This second step is a direct consequence of the change in inclination between an adjacent cytosine base, which has an inclination of -12 degrees, and the next base, a guanine, which has 3 degrees inclination. This bend is a combination of tilt and roll. The large change in inclination allows the formation of a hydrogen bond between the protons of N4 of the 3' cytosine and the O6 of the next 3' base, a guanine, stabilizing the roll component in the bend. These structural features differ from existing models for A-tract bends.For comparison, we also determined the structure of the control sequence, d(GGCAAGAAACGG)/d(CCGTTTCTTGCC), with an AT to GC transition in the center of the A-tract. This structure has no negative inclination in most of the bases within the A-tract, resulting in a bend of only 9 degrees. When ligated in phase, the control sequence has nearly normal mobility in gel electrophoresis experiments.
Optimizing the close-to-carrier phase noise of monolithic CMOS-MEMS oscillators using bias-dependent nonlinearity

A fully monolithic 1.12-MHz CMOS-MEMS nonlinear oscillator comprising a double-ended tuning fork (DETF) resonator and a transimpedance sustaining amplifier has been proposed to enable significant close-to-carrier phase noise (PN) reduction while maximizing its output power for far-from-carrier phase noise improvement. The best-case PN of -77 dBc/Hz at 10-Hz offset, -97 dBc/Hz at 100-Hz offset, and -113 dBc/Hz at 1-kHz offset is realized in a monolithic CMOS-MEMS flexural-mode resonator oscillator for the first time, which is on par with bulk-mode MEMS oscillators using resonator Q > 100,000.
Konstanze Marx & Georg Weidacher. 2014. Internetlinguistik. Ein Lehr- und Arbeitsbuch

Seit den 1990er Jahren hat sich die Linguistik mit dem Sprachgebrauch im Internet einen Gegenstandsbereich erschlossen, der einerseits aufgrund der großen Menge an relativ leicht verfügbaren Daten forschungspraktische Vorteile bietet und andererseits erhebliche theoretische und terminologische Herausforderungen bereithält. Vermeintliche Gewissheiten auf dem Gebiet der Textlinguistik oder in Bezug auf Eigenschaften geschriebener und gesprochener Sprache mussten angesichts neuer Daten und Phänomene grundsätzlich hinterfragt werden. Das Internet mit all seinen verschiedenen, teils recht kurzlebigen Angeboten und Möglichkeiten ist daher ein lohnendes Forschungsfeld für weite Teile der Linguistik: Syntaktiker, Pragmatiker, Textlinguisten, Variationslinguisten, Sprachwandelforscher und andere finden „im Netz“ relevante Daten sowie – zumindest teilweise – ganz neue Fragestellungen. Von einer Teildisziplin „Internetlinguistik“ war dennoch in der deutschsprachigen Linguistik bislang keine Rede und ebenso wenig existierten Einführungsoder Lehrwerke, die Bereiche der Linguistik unter dem Aspekt ihrer Beschäftigung mit Internetdaten bündelten. Im englischsprachigen Raum gibt es das bekannte Buch „Internet Linguistics“ von David Crystal (Crystal 2011), allerdings ist die Bezeichnung „Computer-Mediated Communication“ stärker verbreitet und akzeptiert (vgl. etwa Herring, Stein & Virtanen 2013) – damit ist jedoch keine Disziplin, sondern ein Phänomenbereich bezeichnet. Eine Eingrenzung des Gegenstands ist hier letztlich auch sinnvoller als immer neue Namen für angebliche linguistische Teildisziplinen, wenn die fraglichen Disziplinen nicht über genuine Gegenstände und Methoden definiert werden können. Dies trifft m. E. auch auf die Disziplin „Internetlinguistik“ zu. Eine angemessene Eingrenzung des Gegenstandsbereichs ist im Übrigen äußerst komplex (vgl. Jucker & Dürscheid 2012): ‚Das‘ Internet ist ein heterogenes Phänomen und per se noch kein Gegenstand der Linguistik; die verwendete Hardware („computermediated“) ist nicht unbedingt relevant, da Internetdienste auch mit Smartphones genutzt werden können; semiotische Ressourcen sind, wie z. B. bei gleichzeitiger Nutzung von Videotelefonie und Chat, kaum zu trennen. Demnach wirft bereits der – vermarktungstechnisch
Ethnic Tolerance: A Function of Social and Personal Control

Socioeconomic charateristics failed to explain the variations in ethnic hostility found in an intensively studied group of veterans. A significant association emerged between ethnic hostility and social mobility, as well as feelings of deprivation. The character of the person's controls, particularly his tendency to submit to social controls, accounted for tolerance of minorities in line with the level of the community's "tolerance" of these minorities. The stereotypes used to describe Jews and Negroes are related to the individual's defensive needs.
In vitro production of bovine embryos using individual oocytes

The development of a bovine in vitro embryo production system where individual oocytes could be followed through to the morula or blastocyst stage would be of interest to several fields of study and would allow us to characterise developmentally competent oocytes and their corresponding follicular environment. Several studies have, however, reported significantly reduced embryo development when oocytes or embryos were cultured individually compared to in groups. The aim of this study was to establish such an embryo production system, with embryo development rates similar to that observed under control (grouped) conditions. This study showed that conservation of the oocyte/embryo medium densities generally employed for grouped culture does not facilitate embryo development if oocytes/embryos are cultured individually. However, individual oocytes could effectively undergo IVM/IVF/IVC to the expanded blastocyst stage with some small modifications to the standard protocol. Individual IVF was effective if carried out in either 100 μl of medium in wells or in 50 μl droplets. Individual IVC, if carried out in 10 or 20 μl droplets of SOF with FCS added at either 0 or 24 hr, was effective in terms of blastocyst yields but 20 μl droplets did yield significantly fewer hatched blastocysts compared to grouped controls (P < 0.05). An entirely individual embryo production system was effective when it included individual IVM in 10 μl droplets of M199 + 10 ng/ml EGF resulting in day 8 blastocyst yields not significantly different from controls (38% vs. 35% respectively). The use of 10% FCS during individual IVM appeared, at least under our experimental conditions, to be detrimental to subsequent development. The uses of an individual system for embryo production are many and varied. The results of this study show clearly that a large proportion of bovine oocytes can develop to the blastocyst stage when matured, fertilized, and cultured individually. This opens the way for studies regarding the quality of specific oocytes in such a way as will greatly improve our understanding of the events of late folliculogenesis. © 1996 Wiley‐Liss, Inc.
Effect of movement on dipolar source activities of somatosensory evoked potentials

The early scalp somatosensory evoked potentials (SEPs) to median and tibial nerve stimulation were recorded at rest and during voluntary movement of the stimulated hand and foot, respectively. Both tibial and median nerve SEP distributions at rest could be explained by four‐dipole models, in which one dipole was activated at the same latency as the subcortical far field and the three remaining dipolar sources were located in the perirolandic region contralateral to the stimulated side. Voluntary movement reduced all cortical dipoles in strength, while the subcortical one remained unchanged, suggesting that the effect of movement occurs above the cervicomedullary junction. In animals, cutaneous inputs are suppressed during movement and we therefore interpreted the depression of activity in the primary somatosensory cortex induced by movement as due to selective “gating” of cutaneous afferents. Because the reduction in strength of the cortical dipoles was generally lower during passive than active movement, both centrifugal and centripetal mechanisms probably contribute to the phenomenon of “gating. ” © 1999 John Wiley & Sons, Inc.

The use of scale invariant feature transform (SIFT) algorithms to identification garbage images based on product label

Garbage has become a serious problem, especially in major cities. Garbage basically contain elements of organics and non-organic mixed. In a large volume, the separation of organic and non-organic become difficult jobs and longer if done conventionally. Separation is the identification of objects with one another to be classified. Along with the development of technology, it is possible to design intelligent machines capable of identifying organic and non-organic objects, then the machine can separate quickly. Attributes organic and non-organic element can be recognized from the product label and can be a special characteristic. In this experiment, the algorithm SIFT (Scale invariant Feature Transform) to extract the characteristics of the image garbage label. This technique makes use keypoint or image features garbage properly. Based on the experimental results, the method of identification of organic and non-organic using SIFT algorithm gives results with an average accuracy of 89.9%. With a high level of complexity of a large garbage collection, the performance results including good category.
A Compact Frequency-Reconfigurable Multiband LTE MIMO Antenna for Laptop Applications

A compact frequency-reconfigurable multipleinput-multiple-output (MIMO) antenna on a laptop is proposed for multiband LTE services. Each MIMO antenna consists of two planar inverted-F antenna (PIFA) elements, using a T-shaped dc line and two p-i-n diodes (D1 and D2), in conjunction with the proximity-coupled feed structure. By effectively minimizing its dimension and its interference with antenna performance, the proposed T-shaped dc line is designed to fit within the proximity-coupled feed structure. The proposed MIMO antenna covers the LTE 17/13 bands (704-787 MHz, VSWR <; 3) at State 1 (D1 and D2: ON state), and the LTE 20/7 bands (791-862 MHz, 2500-2690 MHz, VSWR <; 3) at State 2 (D1 and D2: OFF state). The proposed antenna obtains high isolation (> 20 dB), low envelope correlation coefficient (ECC <; 0.0161), and total efficiency of greater than 51%, for all operating frequency bands.
Cancer Statistics, 2008

Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Incidence and death rates are age‐standardized to the 2000 US standard million population. A total of 1,437,180 new cancer cases and 565,650 deaths from cancer are projected to occur in the United States in 2008. Notable trends in cancer incidence and mortality include stabilization of incidence rates for all cancer sites combined in men from 1995 through 2004 and in women from 1999 through 2004 and a continued decrease in the cancer death rate since 1990 in men and since 1991 in women. Overall cancer death rates in 2004 compared with 1990 in men and 1991 in women decreased by 18.4% and 10.5%, respectively, resulting in the avoidance of over a half million deaths from cancer during this time interval. This report also examines cancer incidence, mortality, and survival by site, sex, race/ethnicity, education, geographic area, and calendar year, as well as the proportionate contribution of selected sites to the overall trends. Although much progress has been made in reducing mortality rates, stabilizing incidence rates, and improving survival, cancer still accounts for more deaths than heart disease in persons under age 85 years. Further progress can be accelerated by supporting new discoveries and by applying existing cancer control knowledge across all segments of the population.
