Gene expression in gastric biopsies from patients infected with Helicobacter pylori

Background: Helicobacter pylori infection has protean effects on gene expression in the host gastric mucosa, which have been investigated by gene chip analysis in vitro. In this study the effects of H. pylori infection on host gene expression in the gastric antral mucosa in patients were examined. Methods: One gastric antral biopsy was obtained from a total of 18 untreated patients undergoing routine endoscopic evaluation of chronic abdominal complaints. Nine patients had histologic evidence of H. pylori infection and 9 age- and sex-matched patients had no histologic evidence of H. pylori infection. A microarray analysis was performed using a gene chip containing 35,000 human expressed sequence tags on RNA extracted from endoscopic, gastric antral biopsies, and average gene expression among infected and uninfected patients was compared. Results: Underexpressed genes in infected patients' mucosa included gastric intrinsic factor and several metallothionein isoforms. Overexpressed genes in infected patients' mucosa comprised MHC Class II molecules, immunoglobulin and B-cell activation genes, as well as genes known to induce apoptosis. Changes in expression were confirmed for a subset of genes by SYBR green real-time PCR. Conclusions: Microarray analysis of antral biopsies from patients with and without H. pylori infection revealed differential expression of metal regulatory, immunity and inflammation-related genes.
NiFe Underlayer Effect On Exchange Coupling Field And Coercivity In NiFe/FeMn Films

The effect of NiFe texture on the exchange coupling field and coercivity of Ta/NiFe/FeMn films was studied by varying the deposition conditions of dc magnetron-sputtered NiFe films. By decreasing argon pressure or by increasing substrate bias, strongly textured, large grains of NiFe(111) were grown, yielding highly oriented FeMn(111) texture. Well oriented NiFe(111)/FeMn(111) films yielded the highest exchange anisotropy (0.14 erg/cm/sup 2/), lowest coercivity (/spl ap/2 Oe), and highest blocking temperature (200/spl deg/C) ever reported.
DIFFERENTIATING BETWEEN AUTOMATIC AND STRATEGIC CONTROL PROCESSES: TOWARD A MODEL OF COGNITIVE MOBILIZATION IN BILINGUAL READING

Recent years have witnessed an increased interest in studying the effect of first language (L1) reading experience on second language (L2) literacy. Such cross-language influence in reading is understood as a particular case of the more general phenomenon of cognitive mobilization, which refers to the application of L1-related mechanisms to L2 processing (Ellis, 1994). In this paper, we propose a model of cognitive mobilization for the bilingual reader. The model postulates an L1 and an L2 word recognition system the automaticity of which depends on language proficiency, and a language-neutral central system which entails effortful, strategic control processes. Under the assumptions of limited attentional resources and increasing L2 word recognition automaticity due to enhanced L2 proficiency, the model makes different predictions about cognitive mobilization in reading for bilingual readers at various levels of L2 proficiency. L1-to-L2 mobilization and top- down application of general reading strategies to L2 word decoding are similarly modelled. The paper contributes to the area by providing a framework for the formulation of working hypotheses about cognitive mobilization in reading.
Positional Constraints in Optimality Theory and Harmonic Grammar

The ability of weighted constraints to model certain patterns that elude ranked constraints has often been taken to be typologically problematic (e.g., Prince & Smolensky 1993/2004, Legendre, Sorace & Smolensky 2006). This paper argues that the greater power of weighted constraints can actually be advantageous, permitting a smaller set of more general constraints to be employed in the analysis of attested languages. With limitations on the set of constraints, the predicted typology is restricted beyond what is possible in OT where more, and more specific, constraints are necessary. These principled revisions to CON mean that the languages generated by Harmonic Grammar need not be a superset of those generated by Optimality Theory (see also Pater [this volume], Potts et al. 2010).
New Zealand students' perceptions of parental involvement in learning and schooling

This study investigated the relation between multidimensional aspects of high school students' perceptions of their parental involvement and their achievement. It explored differences in socio-economic backgrounds, ethnicity, gender, and higher and lower achieving students, and a structural model was developed to further investigate these relations. A parental involvement questionnaire and measures of efficacy, liking and achievement in mathematics and reading were administered to a sample of 1,554 New Zealand high school students from 59 schools. In the view of students, there is support for parents to be talking to their children about learning and schooling and having high expectations of them and their future in learning, especially for lower achieving students. Students who claim that their parents are talking with their teachers or attending school meetings are more likely to have lower achievement. The implications from this study relate to developing student self-regulation for learning in home, providing more surface than deeper learning as homework, and assisting parents to learn the language of learning and schooling.
Childhood behaviour and adult personality in male and female subjects

In a follow‐up study, teacher ratings of behaviour at 13 years of age were analysed in relation to personality factors in adults (mean age 27 years) for a group of 77 male and 84 female subjects. In the male group, ratings of Aggressiveness, Motor Restlessness, and Concentration Dificulties correlated positively with a broad psychopathy‐related factor. Furthermore, ratings of Timidity correlated positively with two anxiety factors. In the female group, ratings of Motor Restlessness correlated positively with an extraversion factor. The rated childhood behaviours and the adult personality factors were assumed to be a differential reflection of vulnerability to externalizing and internalizing psychosocial disturbances.
Ranking the Best Instances

We formulate a local form of the bipartite ranking problem where the goal is to focus on the best instances. We propose a methodology based on the construction of real-valued scoring functions. We study empirical risk minimization of dedicated statistics which involve empirical quantiles of the scores. We first state the problem of finding the best instances which can be cast as a classification problem with mass constraint. Next, we develop special performance measures for the local ranking problem which extend the Area Under an ROC Curve (AUC) criterion and describe the optimal elements of these new criteria. We also highlight the fact that the goal of ranking the best instances cannot be achieved in a stage-wise manner where first, the best instances would be tentatively identified and then a standard AUC criterion could be applied. Eventually, we state preliminary statistical results for the local ranking problem.
Fusion of face and periocular information for improved authentication on smartphones

Authentication on smartphones for high valued transactions in e-banking applications require authentication methods that are both more robust and more convenient than simple PIN based authentication. Although a two factor authentication approach can increase the system security, the second factor has to be robust enough not to be compromised by simple attacks. Face and periocular based biometrics have been explored in many works for authentication on smartphone. Multi-modal biometrics always have an edge over the unimodal biometrics. In this work, we explore various multi-modal biometrics employing feature level and score level fusion to improve the biometric performance of the system. An extensive number of experiments are conducted using two different devices - Samsung Galaxy S5 smartphone and Samsung Galaxy Note 10.1 tablet. The database consisting of 46 subjects has provided a performance with best Genuine Match Rate (GMR) of 95.52% for smartphone and 96.65% GMR for tablet. The obtained scores for feature level and score level fusion advocates the use of a fused approaches over a unimodal biometric authentication on the smartphones.
Refined analytic torsion as an element of the determinant line

We construct a canonical element, called the refined analytic torsion, of the determinant line of the cohomology of a closed oriented odd-dimensional manifold M with coefficients in a flat complex vector bundle E . We compute the Ray‐Singer norm of the refined analytic torsion. In particular, if there exists a flat Hermitian metric on E , we show that this norm is equal to 1. We prove a duality theorem, establishing a relationship between the refined analytic torsions corresponding to a flat connection and its dual. 58J52; 58J28, 57R20
Journal of Emerging Trends in Computing and Information Sciences a Watermarking of Medical Image: Method Based "lsb"

In this paper, we present a new approach for watermarking of medical image that we are trying to adapt to telemedicine. This approach is intended to insert a set of data in a medical image. These data should be imperceptible and robust to various attacks. It's containing the signature of the original image, the data specific to the patient and his diagnostic. The purpose of the watermarking method is to check the integrity and preservation of the confidentiality of patient data in a network sharing. This approach is based on the use the LSB (least significant bits) of the image and tools borrowed from cryptography.
Widow's Grief: The Impact of Age and Mode of Death

Two variables (age and mode of death) were tested to discover if they could predict the intensity of the grief reaction. It was hypothesized that widows who experienced anticipatory grief would resolve the bereavement crisis in an easier manner than those experiencing the sudden death of a mate, and that younger widows would experience the effects of acute grief to a greater degree than older widows. Information was obtained by a questionnaire from eighty widows bereaved six to nine months. They were divided into three age groups (young, middle, old) and two mode of death groups (sudden death and prolonged death). It was concluded that anticipatory grief is a mitigating influence on post-mortem grief for the young bereaved widow. It appears, however, that age is a more important factor than mode of death in relating to the intensity of the grief reaction. The restlessness symptom was found to be significantly higher in young widows and the irritability symptom showed an interaction effect-high for young (sudden) and middle (prolonged) widows.
A novel noise-free jamming technique against LFM-PC search radar

Linear Frequency Modulation - Pulse Compression (LFM-PC) search radars have a high processing gain that improves their detection performance even at low values of Signal-to Noise Ratio (SNR). To deny the radar detection, the jammer should use high jamming power to overcome this high processing gain which increases the required Jamming-to-Signal Ratio (JSR) is, in most cases, extravagant and unachievable. This paper introduces a novel jamming technique designated as bandwidth shift jamming. The proposed jamming technique generates a replica of the intercepted radar signal but with a small shift in bandwidth. Jamming effectiveness of the proposed technique is evaluated on a typical modern search radar model with three different types of detectors: fixed threshold, Cell Average and Greatest Of Constant False Alarm Rate (CA-CFAR, GO-CFAR). Moreover, matched filter response to the proposed jamming signal is determined and the optimum parameters of the jamming signal are identified to maximize jamming effectiveness. The results show that the proposed jamming technique needs a JSR of -6 dB at least to be effective against LFM-PC search radar.
Pupil Tutoring: The Educational Conjuring Trick.

Abstract A pilot project for pupil tutoring was undertaken in which six ‘persistent truants’ (aged 15 plus) were placed in a Primary School to tutor twelve children aged 5‐8 who had been identified as ‘slow learners’ by their teacher. Each pupil tutor was responsible for tutoring two of the younger children. Pupil tutors attended for 82#fr1/2> hour sessions. Improvements were noted in pupil tutors’ attitudes to school and teachers, self‐concept, basic skills of reading and writing and their understanding of child rearing practices. The teacher of the pupil tutees noted improvements in their language and reading skills as a results of the programme.
Prognostic markers in older patients starting renal replacement therapy.

AIMS We assessed all patients starting renal replacement therapy during a 1-year period to identify factors influencing 1-year survival in older and younger dialysis patients. METHODS Data was collected from 113 patients. Twenty-four possible prognostic factors were introduced into a multivariate, time-based analysis. RESULTS Hazard ratios, and hence risk of mortality, were increased with increasing alcohol consumption, cardiac dyskinesis, age at onset of dialysis, serum phosphate, number of comorbid illnesses, and Karnofsky score (listed in decreasing order of risk). Risk of death within 1 year was reduced in patients with normal serum albumin and higher Barthel scores at the time of commencing dialysis. No age interactions were found. In the elderly age group the risk of death was also increased if left ventricular dilatation was present. Comorbidity and the age of onset were not independent risk factors in patients aged over 65 years at the time of starting dialysis. CONCLUSIONS All factors listed above increase the 1-year mortality of elderly patients. Factors known to increase medium-term morbidity in dialysis patients including diabetes mellitus, ischaemic heart disease, and hypertension do not appear to be important in the short-term survival of older patient on dialysis.
The Borderline Syndromes: Constitution, Personality, and Adaptation.

of both the leaders and their followers, who he saw in the relatively free-associative interviews, would be buttressed. Our curiosity about the personality structure of the Kapvahiv shaman could also have been satisfied to a degree. Nevertheless, this book, as it stands, is very well done and deserves the careful study of all who are interested in culture and personality studies and in the subject of leadership. It affirms anew the great value of the psychoanalytic method for the social sciences, as do other recent s t u d i e ~ . ~
Improving the banking system : the Chilean experience 1

This paper presents some evidence on the current state of the banking system in Chile, with particular focus on the adjustments it must undergo to comply with the Basel II Capital Accord. We present some basic facts about the Chilean banking system and a brief international comparison. We consider separately local banks, the country’s publicly owned bank and foreign banks, and present the evolution of some basic indicators of performance. The evidence shows some important efficiency gains over time. We also examine issues like the changing procyclicality of banks’ lending and the changes in capital requirements which will result from the adoption of Basel II. The Chilean banking system is well prepared to implement Basel II, albeit in a gradual way.
Geographic distribution of an extinct equid (Equus hydruntinus: Mammalia, Equidae) revealed by morphological and genetical analyses of fossils

Equus hydruntinus inhabited Europe and the Middle East for more than 300 000 years. For a long time, palaeontological data failed to place E. hydruntinus into the equid phylogenetic tree, confronted with the fact that it shares primitive Equus characters with both zebras and asses, and derived characters with asses and hemiones. However, the study of a recently discovered skull points to a relationship with hemiones. Extraction of DNA from ancient samples from Crimea (E. hydruntinus) and Iran (E. cf. hydruntinus) yielded 134–288 bp of the mtDNA control region and 143 bp of the cytochrome b gene. This DNA analysis supports the proximity of E. hydruntinus and Equus hemionus suggested by skull and limb bone analyses, and rejects proximity to either Equus burchelli or the asses suggested by tooth morphology. Dental morphology may thus be of poor taxonomical value if used alone for establishing equid phylogenetic relationships. Furthermore, the small genetic distance between E. cf. hydruntinus of Iran and the classical E. hydruntinus of Crimea suggests that both samples belong to the same species. Accordingly, the geographic range of E. hydruntinus— until now believed to be restricted to Europe, Israel, and Turkey — can be extended towards East as far as Iran.
Repetitive Transcranial Direct Current Stimulation Induced Excitability Changes of Primary Visual Cortex and Visual Learning Effects—A Pilot Study

Studies on noninvasive motor cortex stimulation and motor learning demonstrated cortical excitability as a marker for a learning effect. Transcranial direct current stimulation (tDCS) is a non-invasive tool to modulate cortical excitability. It is as yet unknown how tDCS-induced excitability changes and perceptual learning in visual cortex correlate. Our study aimed to examine the influence of tDCS on visual perceptual learning in healthy humans. Additionally, we measured excitability in primary visual cortex (V1). We hypothesized that anodal tDCS would improve and cathodal tDCS would have minor or no effects on visual learning. Anodal, cathodal or sham tDCS were applied over V1 in a randomized, double-blinded design over four consecutive days (n = 30). During 20 min of tDCS, subjects had to learn a visual orientation-discrimination task (ODT). Excitability parameters were measured by analyzing paired-stimulation behavior of visual-evoked potentials (ps-VEP) and by measuring phosphene thresholds (PTs) before and after the stimulation period of 4 days. Compared with sham-tDCS, anodal tDCS led to an improvement of visual discrimination learning (p < 0.003). We found reduced PTs and increased ps-VEP ratios indicating increased cortical excitability after anodal tDCS (PT: p = 0.002, ps-VEP: p = 0.003). Correlation analysis within the anodal tDCS group revealed no significant correlation between PTs and learning effect. For cathodal tDCS, no significant effects on learning or on excitability could be seen. Our results showed that anodal tDCS over V1 resulted in improved visual perceptual learning and increased cortical excitability. tDCS is a promising tool to alter V1 excitability and, hence, perceptual visual learning.
Epidemiology, Risk Factors, and Clinical Features of Intracerebral Hemorrhage: An Update

Intracerebral hemorrhage (ICH) is the second most common subtype of stroke and a critical disease usually leading to severe disability or death. ICH is more common in Asians, advanced age, male sex, and low- and middle-income countries. The case fatality rate of ICH is high (40% at 1 month and 54% at 1 year), and only 12% to 39% of survivors can achieve long-term functional independence. Risk factors of ICH are hypertension, current smoking, excessive alcohol consumption, hypocholesterolemia, and drugs. Old age, male sex, Asian ethnicity, chronic kidney disease, cerebral amyloid angiopathy (CAA), and cerebral microbleeds (CMBs) increase the risk of ICH. Clinical presentation varies according to the size and location of hematoma, and intraventricular extension of hemorrhage. Patients with CAA-related ICH frequently have concomitant cognitive impairment. Anticoagulation related ICH is increasing recently as the elderly population who have atrial fibrillation is increasing. As non-vitamin K antagonist oral anticoagulants (NOACs) are currently replacing warfarin, management of NOAC-associated ICH has become an emerging issue.
Feeling Like a Domestic Goddess

This article examines the significance of cookery writer and television cook Nigella Lawson in relation to debates about postfeminism, arguing that her work negotiates a form of feminine identity between the frequently polarized figures of `the feminist' and `the housewife'. It locates Nigella's work within feminist research into the meanings that women bring to their cooking practices within the sexual division of labour, arguing that her work offers an alternative way of imaging women's relationship to food based on the pleasures of cooking and eating rather than pleasing others. The article draws on Ang to explore how the figure of the domestic goddess constructed by Nigella offers a means of negotiating temporal constraints at the level of fantasy.
The Gender–Ambivalent Group and the Gender–Blinded Analyst

Group therapists must pay careful attention to gender-related issues appearing in groups. While this may appear obvious, in practice there is often a reluctance to do so. This is in part owing to the fact that exploring gender-related differences may threaten group harmony. The present article shows first how this ambivalence is reflected historically in the group therapy literature. It then brings case examples of group sessions which demonstrate such ambivalence. Reasons for the ambivalence are offered in the discussion section. It is suggested that while open exploration of gender tension may lead to acrimony or embarrassment, ultimately the group learns it can contain these feelings, survive and in fact achieve a more solid and lasting cohesion.
Salmonella choleraesuis as an anticancer agent in a syngeneic model of orthotopic hepatocellular carcinoma

Some anaerobic and facultative anaerobic bacteria represent novel therapeutic agents that have been recently applied in cancer therapy. Previously, we found that Salmonella choleraesuis in combination with cisplatin could retard tumor growth in the murine subsutaneous hepatocellular carcinoma (HCC) model. In this regard, we investigated the antitumor activity of S. choleraesuis in the ML‐1 orthotopic tumor model. Systemically administered S. choleraesuis accumulated within not only subcutaneous but also orthotopic tumors for at least 30 days, forming tumor‐to‐normal tissue ratios exceeding 1,000–10,000 to 1. The antitumor effects of S. choleraesuis were evaluated in mice bearing subcutaneous and orthotopic ML‐1 tumors. Compared with the control treatment, S. choleraesuis significantly prolonged the animal survival, reduced the tumor size, as well as upregulated interferon (IFN)‐γ and induced IFN‐inducible chemokines CXCL10 (IP‐10) productions. Furthermore, immunohistochemical staining of the tumors revealed decreased intratumoral microvessel density, increased infiltration of neutrophils, CD4+ and CD8+ T cells, and induced cell death in tumor microenvironment. In conclusion, these results suggest that tumor‐targeted therapy using S. choleraesuis, which exerts tumoricidal and antiangiogenic activities, represents a potential strategy for the treatment of HCC. © 2007 Wiley‐Liss, Inc.
Conditional Euro Area Sovereign Default Risk

We propose an empirical framework to assess the likelihood of joint and conditional sovereign default from observed CDS prices. Our model is based on a dynamic skewed-t distribution that captures all salient features of the data, including skewed and heavy-tailed changes in the price of CDS protection against sovereign default, as well as dynamic volatilities and correlations that ensure that uncertainty and risk dependence can increase in times of stress. We apply the framework to euro area sovereign CDS spreads during the euro area debt crisis. Our results reveal significant time-variation in distress dependence and spill-over effects for sovereign default risk. We investigate market perceptions of joint and conditional sovereign risk around announcements of Eurosystem asset purchases programs, and document a strong impact on joint risk.
