    To explore whether young adolescents consuming alcohol and energy drinks combined were more likely to report negative behavioural outcomes than their peers who drink only one type of these beverages or are abstinent. We analysed data on a representative sample of Slovak adolescents 8502 adolescents (mean age 13.21, 49.4 % boys) from the 2014 Health Behaviour in School-aged Children cross-sectional study. We assessed the associations of alcohol and energy drinks consumption with negative outcomes and their potential synergy, as measured by the synergy index (SI). Adolescents consuming both alcohol and energy drinks were at higher risk of negative behavioural outcomes than their peers who drank only alcohol or energy drinks or were non-consumers. Consumers of alcohol and energy drinks were highly prone to be involved in fighting-the joint association of alcohol and energy drinks consumption was greater than sum of its associations separately in relation to fighting (SI 1.49; 95 % confidence interval 1.03-2.16). Preventive strategies should aim at increasing awareness of negative behavioural outcomes-especially aggressive behaviour associated with alcohol and energy drinks consumption among young adolescents.

    Dvoeglazov, Valeriy V

    2011-01-01

    It is easy to check that both algebraic equation Det (\\hat p - m) =0 and Det (\\hat p + m) =0 for 4-spinors u- and v- have solutions with p_0= \\pm E_p =\\pm \\sqrt{{\\bf p}^2 +m^2}. The same is true for higher-spin equations. Meanwhile, every book considers the p_0=E_p only for both u- and v- spinors of the (1/2,0)\\oplus (0,1/2)) representation, thus applying the Dirac-Feynman-Stueckelberg procedure for elimination of negative-energy solutions. Recent works of Ziino (and, independently, of several others) show that the Fock space can be doubled. We re-consider this possibility on the quantum field level for both s=1/2 and higher spins particles.

    2016-10-01

    We consider entanglement criteria based on the spin squeezing inequalities for arbitrary spin systems. Here we use the negative correlations to detect the entanglement in the system with exchange symmetry. For arbitrary spin systems, we can find that the state is entangled, when the minimal pairwise correlation is negative. Then we give a parameter which is defined by the collective angular momentum operator, to detect the entanglement for the Dicke state with N spin -1 particles, and the results are as the same as negative correlation. We also consider the directions of negative correlation, the state is entangled in two orthogonal directions for the superposition of Dicke state without parity.

  7. The Relationship between Negative Affect and Reported Cognitive Failures

    Full Text Available The purpose of this study was to expand our understanding of the range of negative affect associated with reported problems with everyday functions and activities, measured by the cognitive failures questionnaire (CFQ. Evidence from previous research indicates that individuals meeting criteria for mood disorders, such as major depression or seasonal affective disorder, experience cognitive deficits in memory and attention that can lead to problems with everyday activities reported in the CFQ. The Positive and Negative Affect Scale (PANAS was used to assess potential correlations with a wider range of negative emotions. Findings for a sample of 129 college students revealed that negative affective experiences were significantly correlated with failures of memory and attention on the CFQ (fear = .41, hostility = .38, sadness = .28, and guilt = .43. Conversely, positive affect was negatively correlated with distractibility (r=−.21. Additional affective scales on the PANAS (e.g., shyness and fatigue were also associated with higher reports of cognitive failures. The results provide converging evidence of a relationship between negative affective experiences and reported frequency of problems on the cognitive failures questionnaire.

    Full Text Available The paper shows that nowadays the Internet is increasingly used in higher education. It is argued that the main directions of research use the Internet show a positive effect of using a global network of higher education. It was revealed that in addition to the positive influence of the Internet network has a signifi cant negative impact. Identifi ed such negative factors as the widespread learning task solving and quick copying in the case of the emergence of new jobs. Not shown the ability to publish new textbooks in applying active methods lectures, due to these facilities benefi ts the Internet. The prevalence of false information on the Internet. The question of providing students with the information as it is fi nished, it is shown that in some cases it is not advisable to do. It is said that the publication of the full study guides is suitable only in the case when it comes to the basic disciplines, in other cases it is doubtful. Analyzed the shortcomings of such methods of struggle with the designated program to identify factors such as plagiarism, limiting the exchange of scientifi c and methodological experience. Revealed such disadvantages of using plagiarism detection software as programs to combat the use of these programs, and others. It is shown that the use of new teaching jobs, may lead to the fact that completed assignments will be distributed by students via the Internet, and thus the depreciation of these tasks will occur. Revealed the following pattern of use of new teaching jobs in higher education: the more effective is the learning task, the greater the likelihood that it will be devalued. The question required a waiver of such types of learning tasks as translation work, which is due to the fact that students are copying term papers or materials to them without even reading them.

    We develop breaking soliton equations and negative-order breaking soliton equations of typical and higher orders. The recursion operator of the KdV equation is used to derive these models.We establish the distinctdispersion relation for each equation. We use the simplified Hirota’s method to obtain multiple soliton solutions for each developed breaking soliton equation. We also develop generalized dispersion relations for the typical breaking soliton equations and the generalized negative-order breaking soliton equations. The results provide useful information on the dynamics of the relevant nonlinear negative-order equations.

  13. Worse Health Status and Higher Incidence of Health Disorders in Rhesus Negative Subjects.

    Directory of Open Access Journals (Sweden)

    Jaroslav Flegr

    Full Text Available Rhesus-positive and Rhesus-negative persons differ in the presence-absence of highly immunogenic RhD protein on the erythrocyte membrane. The biological function of the RhD molecule is unknown. Its structure suggests that the molecular complex with RhD protein transports NH3 or CO2 molecules across the erythrocyte cell membrane. Some data indicate that RhD positive and RhD negative subjects differ in their tolerance to certain biological factors, including, Toxoplasma infection, aging and fatique. Present cross sectional study performed on 3,130 subjects showed that Rhesus negative subjects differed in many indices of their health status, including incidences of many disorders. Rhesus negative subjects reported to have more frequent allergic, digestive, heart, hematological, immunity, mental health, and neurological problems. On the population level, a Rhesus-negativity-associated burden could be compensated for, for example, by the heterozygote advantage, but for Rhesus negative subjects this burden represents a serious problem.

    Non-clinical schizotypy was found to be related to poorer Wisconsin Card-Sorting Test (WCST) performance, but the results were inconsistent. Two subgroups, the higher negative-higher positive and the lower negative-lower positive (15 vs 16), were selected from the top and the bottom quartiles of negative and positive scale scores of the Schizotypal Personality Questionnaire (SPQ) completed by 177 healthy volunteers, respectively. The higher negative-higher positive SPQ score subgroup had significantly poorer performance regarding the completed categories of WCST than the lower negative-lower positive SPQ score subgroup. Subjects with higher non-clinical schizotypy trait showed relatively mild cognitive dysfunction.

    In the reform of educational structure in China recently, vocational education is being focused and higher vocational edu⁃cation is developing rapidly. With the increase of student enrollment in Higher Vocational Technical College (HVTC), the quality of students is declining in the meantime and especially the students who major in English have a low proficiency in English lan⁃guage. This thesis explores the theory of phonetics and the theory of transfer in second language learning and deals with negative transfer of mother tongue in segmental and supra-segmental levels to HVTC students when they learn English pronunciation and intonation.

  17. Retrospective Reports of Childhood Misfortune Are Associated With Positive and Negative Affect in Adulthood.

    Childhood misfortune refers to nonnormative experiences individuals encounter at younger ages that affect development across the life span. This study examined whether retrospectively reported childhood misfortune was associated with negative and positive affect in adulthood. In addition, we explored whether perceived control beliefs would moderate these associations. We used archival data from 6,067 adults ( Mage = 46.86; range = 20-75) from the Midlife Development in the United States study. Higher levels of misfortune were associated with higher levels of negative affect and lower levels of positive affect in adulthood. However, control beliefs moderated this association such that the combination of higher perceived control and misfortune resulted in less of a decrease in positive affect and less of an increase in negative affect. Overall, early life events were associated with later life emotional health, and control beliefs were an important psychological resource that buffered the negative effects of childhood misfortune.

    Whooping cough or pertussis is a highly infectious respiratory disease in humans caused by Bordetella pertussis. The use of acellular vaccines (ACV) has been associated with the recent resurgence of pertussis in developed countries including Australia despite high vaccination coverage where B. pertussis strains that do not express pertactin (Prn), a key antigenic component of the ACV, have emerged and become prevalent. In this study, we used an in vivo competition assay in mice immunised with ACV and in naïve (control) mice to compare the proportion of colonisation with recent clinical Prn positive and Prn negative B. pertussis strains from Australia. The Prn negative strain colonised the respiratory tract more effectively than the Prn positive strain in immunised mice, out-competing the Prn positive strain by day 3 of infection. However, in control mice, the Prn positive strain out-competed the Prn negative strain. Our findings of greater ability of Prn negative strains to colonise ACV-immunised mice are consistent with reports of selective advantage for these strains in ACV-immunised humans.

  19. Conflict, negative emotion, and reports of partners' relationship maintenance in same-sex couples.

    Ogolsky, Brian G; Gray, Christine R

    2016-03-01

    The literature on relationship maintenance has focused primarily on the beneficial outcomes of maintenance, and, as a result, little is known about relational processes that may interfere with reports of partners' maintenance. The authors examine how daily conflict influences individuals' reports of their partners' maintenance, and how a constructive communication style buffers this influence by reducing negative emotion on conflict days. In a daily diary study of 98 same-sex couples in romantic relationships, they found that the negative association between conflict and reports of a partner's relationship maintenance was mediated by negative emotion. That is, there was an indirect effect by which daily conflict was associated with higher levels of daily negative emotion, which was associated with reports of lower levels of partners' relationship maintenance. This indirect effect was moderated by couples' overall level of constructive communication such that higher levels diminished the degree to which couples experienced negative emotion on days with episodes of relational conflict. The authors discuss results in the context of interpersonal theory and provide implications for clinicians and practitioners.

    Russell body gastritis is an unusual form of chronic gastritis characterized by the permeation of lamina propria by numerous plasma cells with eosinophilic cytoplasmic inclusions. Very few cases have been reported in the literature; the majority of which have shown Helicobacter Pylori (H. pylori) infection, thus suggesting a correlation between plasma cell presence and antigenic stimulation by H. pylori. We present a case of Russell body gastritis in a 78-year-old woman who was undergoing esophagogastroduodenoscopy for epigastric pain. Gastric biopsy of the gastroesophageal junction showed the presence of cells with periodic acid-Schiff-positive hyaline pink bodies. Giemsa staining for H. pylori infection was negative, as well as immunohistochemical detection. The cells with eosinophilic inclusions stained positive for CD138, CD79a, and κ and lambda light chains, which confirmed plasma cell origin. In particular, κ and lambda light chains showed a polyclonal origin and the patient was negative for immunological dyscrasia. The histological observations were confirmed by ultrastructural examination. The cases reported in the literature associated with H. pylori infection have shown regression of plasma cells after eradication of H. pylori. Nothing is known about the progression of H. pylori-negative cases. The unusual morphological appearance of this type of chronic gastritis should not be misinterpreted during routine examination, and it should be distinguished from other common forms of chronic gastritis. It is mandatory to exclude neoplastic diseases such as gastric carcinoma, lymphoma and plasmocytoma by immunohistochemistry and electron microscopy, which can help with differential diagnosis. The long-term effects of plasma cells hyperactivation are still unknown, because cases of gastric tumor that originated in patients affected by Russell body gastritis have not been described in the literature. We are of the opinion that these patients should be scheduled

    Holt, Nanna; Mygind, Anna; Bro, Flemming

    2017-02-01

    The Danish childhood vaccination programme offers protection against measles, mumps, and rubella (MMR). Nevertheless, many children appear to be unvaccinated according to the national registers. The aim of this study was to estimate the MMR1 vaccination coverage based on a medical record review of children whose vaccination status is negative according to the register-based data. We conducted a cross-sectional study of 19 randomly selected general practices in the Central Denmark Region including 1,712 children aged 18-42 months. The practices received a registration form listing children with a negative MMR1 vaccination status in the register-based data. The general practices then validated the children's vaccination status by medical record review. In total, 94% of the children had been vaccinated according to the medical records in general practice compared with 86% according to the register-based data. Of the 246 children who were unvaccinated according to the register-based data, 135 (55%) had been vaccinated according to the medical records. This discrepancy was due mainly to administrative reimbursement errors. The MMR1 vaccination coverage in Denmark seems to be considerably higher than reflected in national registers. Using medical record review to re-assess the vaccination status revealed that most of the supposedly unvaccinated children had, in fact, been vaccinated. The Danish Research Foundation for General Practice and the General Practitioners' Foundation for Education and Development. not relevant.

  12. Negative refractive index and higher-order harmonics in layered metallodielectric optical metamaterials

    Maas, Ruben; Parsons, James; Polman, Albert

    2014-01-01

    We study the propagation of light in a three-dimensional double-periodic Ag/TiO2 multilayer metamaterial composed of coupled plasmonic waveguides operating in the visible and UV spectral range. For these frequencies, light propagation in the plane of the waveguides is described by a negative phase velocity, while for the orthogonal direction light propagation is described by a Bloch wave composed of a large number of harmonics. As a result, the material cannot generally be described by a single phase index: decomposing the Bloch wave into different harmonics we show that for the wavelength range of interest the positive index m=1 harmonic dominates the propagation of light in the orthogonal direction. These results are corroborated by numerical simulations and optical refraction experiments on a double-periodic Ag/TiO2 multilayer metamaterial prism in the 380-600 nm spectral range, which show that positive refraction associated with right-handed harmonics dominates. Studying the isofrequency contours we find ...

    2016-01-01

    Full Text Available Negative pressure pulmonary edema (NPPE is a rare complication that can occur after acute upper airway obstruction or secondary to relax chronic upper airway obstruction and a life-threatening fatal condition. The first cause in the etiology of NPPE is developed laryngospasm after intubation or extubation, while the other causes are epiglottitis, croup, hiccups, foreign body aspiration, pharyngeal hematoma and oropharyngeal tumors. Supportive therapy is usually the only treatment. The fundamental principle of treatment is early diagnosis and to provide adequate oxygenation. Application of positive airway pressure is often provided with CPAP in most of patients, but sometimes re-intubation and mechanical ventilation may be required.

  14. Experimental studies of the Negative Ion of Hydrogen. Final Report

    Bryant, Howard C.

    1999-06-30

    This document presents an overview of the results of the DOE'S support of experimental research into the structure and interactions of the negative ion of hydrogen conducted by the Department of Physics and Astronomy of the University of New Mexico at the Los Alamos National Laboratory. The work involves many collaborations with scientists from both institutions, as well as others. Although official DOE support for this work began in 1977, the experiment that led to it was done in 1971, near the time the 800 MeV linear accelerator at Los Alamos (LAMPF) first came on line. Until the mid nineties, the work was performed using the relativistic beam at LAMFF. The most recent results were obtained using the 35 keV injector beam for the Ground Test Accelerator at Los Alamos. A list of all published results from this work is presented.

  15. Visualizing Higher Order Finite Elements: FY05 Yearly Report.

    Energy Technology Data Exchange (ETDEWEB)

    Thompson, David; Pebay, Philippe Pierre

    2005-11-01

    This report contains an algorithm for decomposing higher-order finite elementsinto regions appropriate for isosurfacing and proves the conditions under which thealgorithm will terminate. Finite elements are used to create piecewise polynomialapproximants to the solution of partial differential equations for which no analyticalsolution exists. These polynomials represent fields such as pressure, stress, and mo-mentim. In the past, these polynomials have been linear in each parametric coordinate.Each polynomial coefficient must be uniquely determined by a simulation, and thesecoefficients are called degrees of freedom. When there are not enough degrees of free-dom, simulations will typically fail to produce a valid approximation to the solution.Recent work has shown that increasing the number of degrees of freedom by increas-ing the order of the polynomial approximation (instead of increasing the number offinite elements, each of which has its own set of coefficients) can allow some typesof simulations to produce a valid approximation with many fewer degrees of freedomthan increasing the number of finite elements alone. However, once the simulation hasdetermined the values of all the coefficients in a higher-order approximant, tools donot exist for visual inspection of the solution.This report focuses on a technique for the visual inspection of higher-order finiteelement simulation results based on decomposing each finite element into simplicialregions where existing visualization algorithms such as isosurfacing will work. Therequirements of the isosurfacing algorithm are enumerated and related to the placeswhere the partial derivatives of the polynomial become zero. The original isosurfacingalgorithm is then applied to each of these regions in turn.3 AcknowledgementThe authors would like to thank David Day and Louis Romero for their insight into poly-nomial system solvers and the LDRD Senior Council for the opportunity to pursue thisresearch.

    Deep-bed methyl iodide adsorption testing has continued in Fiscal Year 2016 under the Department of Energy (DOE) Fuel Cycle Technology (FCT) Program Offgas Sigma Team to further research and advance the technical maturity of solid sorbents for capturing iodine-129 in off-gas streams during used nuclear fuel reprocessing. Adsorption testing with higher levels of NO (approximately 3,300 ppm) and NO2 (up to about 10,000 ppm) indicate that high efficiency iodine capture by silver aerogel remains possible. Maximum iodine decontamination factors (DFs, or the ratio of iodine flowrate in the sorbent bed inlet gas compared to the iodine flowrate in the outlet gas) exceeded 3,000 until bed breakthrough rapidly decreased the DF levels to as low as about 2, when the adsorption capability was near depletion. After breakthrough, nearly all of the uncaptured iodine that remains in the bed outlet gas stream is no longer in the form of the original methyl iodide. The methyl iodide molecules are cleaved in the sorbent bed, even after iodine adsorption is no longer efficient, so that uncaptured iodine is in the form of iodine species soluble in caustic scrubber solutions, and detected and reported here as diatomic I2. The mass transfer zone depths were estimated at 8 inches, somewhat deeper than the 2-5 inch range estimated for both silver aerogels and silver zeolites in prior deep-bed tests, which had lower NOx levels. The maximum iodine adsorption capacity and silver utilization for these higher NOx tests, at about 5-15% of the original sorbent mass, and about 12-35% of the total silver, respectively, were lower than for trends from prior silver aerogel and silver zeolite tests with lower NOx levels. Additional deep-bed testing and analyses are recommended to expand the database for organic iodide adsorption and increase the technical maturity if iodine adsorption processes.

    On the basis of the standard linear stability analysis and Drude electromagnetic model,the impacts of higher-order dispersions and three kinds of typical saturable nonlinearities on modulation instability (MI) have been analyzed and calculated for negative-refractive metamaterials (MMs).Our results show that the MI gain spectra consist of only one spectral region instead of one or two regions in ordinary materials,which may be close to or far from the zero point.Particularly,the spectrum far from the zero point has a high cut-off frequency but a narrow spectral width,which is obviously beneficial to the generation of high-repetition-rate pulse trains.Moreover,MI characteristics here will vary with the normalized angular frequency which can be modified by adjusting the structures of negative-refractive MMs,signifying the controllability of bistable solitons and MI based applications.The effects of saturable nonlinearities are similar to those in ordinary materials.

  1. Analysis of Current DNA Encoded Library Screening Data Indicates Higher False Negative Rates for Numerically Larger Libraries.

    2017-04-10

    To optimize future DNA-encoded library design, we have attempted to quantify the library size at which the signal becomes undetectable. To accomplish this we (i) have calculated that percent yields of individual library members following a screen range from 0.002 to 1%, (ii) extrapolated that ∼1 million copies per library member are required at the outset of a screen, and (iii) from this extrapolation predict that false negative rates will begin to outweigh the benefit of increased diversity at library sizes >10(8). The above analysis is based upon a large internal data set comprising multiple screens, targets, and libraries; we also augmented our internal data with all currently available literature data. In theory, high false negative rates may be overcome by employing larger amounts of library; however, we argue that using more than currently reported amounts of library (≫10 nmoles) is impractical. The above conclusions may be generally applicable to other DNA encoded library platforms, particularly those platforms that do not allow for library amplification.

ETS translocation variant 4 (ETV4 is an ETS (E-26 transcription factor and has been associated with tumor metastasis. However, the clinical and functional significance of ETV4 in TNBC still remains unclear. Methods: A human tumor metastasis polymerase chain reaction array was used to profile differential expression of tumor metastasis-related genes in TNBC tissue. Real-time reverse transcription and Western blot analyses were performed to verify ETV4 expression in TNBC cells and tissue. Immunohistochemistry was used to detect expression of ETV4 protein in 135 TNBC tissue samples for association between ETV4 protein expression and clinical outcomes. Results: A total total of eight upregulated (CCL7, KISS1, MET, MMP7, NR4A3, ETV4, TIMP3, and TSHR and three downregulated (ITGA7, SSTR, and MMP2 genes were identified between TNBC tissue and the luminal subtype of breast cancer tissue. ETV4 messenger ribonucleic acid was more than five-fold upregulated in TNBC tissue compared with the control tissue. ETV4 overexpression was found in 57.0% of 135 TNBC cases. Overexpression of ETV4 protein was associated with an advanced stage and a higher proportion of positive lymph node and lymphovascular invasion. Patients with an ETV4

    2011-02-01

    The validity of self-reported suicide attempt information is undermined by false positives (e.g., incidences without intent to die), or by unreported suicide attempts, referred to as false negatives. In a sample of 1,385 Austrian adults, we explored the occurrence of false positives and false negatives with detailed, probing questions. Removing false positives decreased the rate of suicide attempters from 4.3% to 2.7%. Probing questions also revealed 0.8% false negatives. We recommend using probing questions with both those who report a suicide attempt and those who do not report a suicide attempt to increase the validity of self-reported suicide-related information.

  5. Single-gene negative binomial regression models for RNA-Seq data with higher-order asymptotic inference.

    2015-01-01

    We consider negative binomial (NB) regression models for RNA-Seq read counts and investigate an approach where such NB regression models are fitted to individual genes separately and, in particular, the NB dispersion parameter is estimated from each gene separately without assuming commonalities between genes. This single-gene approach contrasts with the more widely-used dispersion-modeling approach where the NB dispersion is modeled as a simple function of the mean or other measures of read abundance, and then estimated from a large number of genes combined. We show that through the use of higher-order asymptotic techniques, inferences with correct type I errors can be made about the regression coefficients in a single-gene NB regression model even when the dispersion is unknown and the sample size is small. The motivations for studying single-gene models include: 1) they provide a basis of reference for understanding and quantifying the power-robustness trade-offs of the dispersion-modeling approach; 2) they can also be potentially useful in practice if moderate sample sizes become available and diagnostic tools indicate potential problems with simple models of dispersion.

    2011-07-01

    Full Text Available AbstractGram-negative folliculitis may be the result of prolonged antibacterial treatments in patients with acne and rosacea. It is caused by alteration of facial skin flora and the nasal mucous, a decrease of Gram-positive bacteria and a proliferation of Gram-negative bacteria (for example Escherichia coli, Pseudomonas aeruginosa, Serratia marcescens, Klebsiella sp. and Proteus mirabilis. It should be considered in patients with acne who have not had a clinical improvement after 3-6 months of treatment with tetracyclines. The disease is underestimated, probably because bacteriological studies are rarely requested and the increased use of oral isotretinoin for acne management. One of the most effective treatments for Gram-negative folliculitis is oral isotretinoin (0.5-1 mg / kg / day for 4-5 months. We report the case of Gram negative folliculitis successfully treated with oral isotretinoin.

    We explore possibility to find out a new model of gravastars in the extended $D$-dimensional Einstein-Maxwell spacetime. The class of solutions as obtained by Mazur and Mottola of a neutral gravastar~\\cite{Mazur2001,Mazur2004} have been observed as an alternative to $D$-dimensional versions of the Schwarzschild-Tangherlini black hole. To tackle the spherical system in a convenient way we have configured that the gravastar consists of three distinct regions with different equations of state as follows: [I] Interior region $0 \\leq r < r_1$,~$\\rho = -p$, [II] Thin shell region $r_1 \\leq r < r_2$,~$\\rho = p$, and [III] Exterior region $r_2 < r$,~$\\rho = p =0$. The outer region of this gravastar model therefore corresponds to a higher dimensional Reissner-Nordstr{\\"o}m black hole. In connection to this junction conditions are provided and therefore we have formulated mass and the related Equation of State of the gravastar. It has been shown that the model satisfies all the requirements of the physical fea...

  9. How is emotional awareness related to emotion regulation strategies and self-reported negative affect in the general population?

    Claudia Subic-Wrana

    Full Text Available OBJECTIVE: The Levels of Emotional Awareness Scale (LEAS as a performance task discriminates between implicit or subconscious and explicit or conscious levels of emotional awareness. An impaired awareness of one's feeling states may influence emotion regulation strategies and self-reports of negative emotions. To determine this influence, we applied the LEAS and self-report measures for emotion regulation strategies and negative affect in a representative sample of the German general population. SAMPLE AND METHODS: A short version of the LEAS, the Hospital Anxiety and Depression Scale (HADS and the Emotion Regulation Questionnaire (ERQ, assessing reappraisal and suppression as emotion regulation strategies, were presented to N = 2524 participants of a representative German community study. The questionnaire data were analyzed with regard to the level of emotional awareness. RESULTS: LEAS scores were independent from depression, but related to self-reported anxiety. Although of small or medium effect size, different correlational patters between emotion regulation strategies and negative affectivity were related to implict and explict levels of emotional awareness. In participants with implicit emotional awareness, suppression was related to higher anxiety and depression, whereas in participants with explicit emotional awareness, in addition to a positive relationship of suppression and depression, we found a negative relationship of reappraisal to depression. These findings were independent of age. In women high use of suppression and little use of reappraisal were more strongly related to negative affect than in men. DISCUSSION: Our first findings suggest that conscious awareness of emotions may be a precondition for the use of reappraisal as an adaptive emotion regulation strategy. They encourage further research in the relation between subconsious and conscious emotional awareness and the prefarance of adaptive or maladaptive emotion

    Patients' appraisal of somatic symptoms is correlated with their negative affect. The authors have investigated whether social desirability is associated with patients' symptom and health behavior reporting. One hundred fourteen surgical cancer patients who participated in either an outpatient or an inpatient follow-up care program filled out the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30, the New Social Desirability Scale, and a health behavior checklist. Patients' reports of somatic symptoms were correlated inversely with social desirability (r = -0.50) and positively with negative affect (r = 0.72). When objective health and demographic variables (e.g., prognosis, adjuvant therapy prior to follow-up, and gender) were entered first in hierarchical multiple regression analyses, social desirability and negative affect accounted for an additional 16% and 36% of the symptom variance, respectively. Similar results were found when global quality of life was the dependent variable. Self-reported health behaviors were explained only through the set of health and demographic variables (14%), and social desirability and negative affect did not account for additional variance. On the average, patients reported that they had a median of 4.7 (out of a list of 21) self-initiated health behaviors, and 11% of the patients admitted to having used unproven therapies. Symptom reports do not give a pure picture of patients' health status, but they are strongly correlated with social desirability and negative affect. Detection of such psychologic variables is essential to understanding the dynamics of quality of life. In applied settings, quality-of-life measures should be used together with conventional criteria. As practical experience and scientific understanding grow, the relative positioning of these patient-oriented versus clinic-oriented endpoints will become clear.

    Mindfulness-based interventions are gaining empirical support as alternative or adjunctive treatments for a variety of mental health conditions, including anxiety, depression, and substance use disorders. Emerging evidence now suggests that mindfulness-based treatments may also improve clinical features of schizophrenia, including negative symptoms. However, no research has examined the construct of mindfulness and its correlates in schizophrenia. In this study, we examined self-reported mindfulness in patients (n=35) and controls (n=25) using the Five-Facet Mindfulness Questionnaire. We examined correlations among mindfulness, negative symptoms, and psychological constructs associated with negative symptoms and adaptive functioning, including motivation, emotion regulation, and dysfunctional attitudes. As hypothesized, patients endorsed lower levels of mindfulness than controls. In patients, mindfulness was unrelated to negative symptoms, but it was associated with more adaptive emotion regulation (greater reappraisal) and beliefs (lower dysfunctional attitudes). Some facets of mindfulness were also associated with self-reported motivation (behavioral activation and inhibition). These patterns of correlations were similar in patients and controls. Findings from this initial study suggest that schizophrenia patients may benefit from mindfulness-based interventions because they (a) have lower self-reported mindfulness than controls and (b) demonstrate strong relationships between mindfulness and psychological constructs related to adaptive functioning.

    We report here on the imaging findings of the case of KIT-negative gastrointestinal stromal tumor (GIST) in the stomach of a 12-year-old girl. Radiologic studies revealed the presence of a huge exophytic growing mass that originated from the gastric wall and this mass consisted of solid and cystic components on USG, CT and MR. The cystic regions were mainly located at the periphery of the mass and they were revealed to be myxoid degeneration and hemorrhage on histopathologic examination. The tumor consisted of epithelioid and typical spindle cells and they showed negative immunoreactivity for KIT. Although KIT-negative GISTs are rare, they can be considered in the differential diagnosis when a large heterogeneous extraluminal mass that contains solid portions and various degrees of peripheral cystic regions is observed

    2011-01-01

    The present study investigated event-related brain potentials elicited by true and false negated statements to evaluate if discrimination of the truth value of negated information relies on conscious processing and requires higher-order cognitive processing in healthy subjects across different levels of stimulus complexity. The stimulus material consisted of true and false negated sentences (sentence level) and prime-target expressions (word level). Stimuli were presented acoustically and no overt behavioral response of the participants was required. Event-related brain potentials to target words preceded by true and false negated expressions were analyzed both within group and at the single subject level. Across the different processing conditions (word pairs and sentences), target words elicited a frontal negativity and a late positivity in the time window from 600-1000 msec post target word onset. Amplitudes of both brain potentials varied as a function of the truth value of the negated expressions. Results were confirmed at the single-subject level. In sum, our results support recent suggestions according to which evaluation of the truth value of a negated expression is a time- and cognitively demanding process that cannot be solved automatically, and thus requires conscious processing. Our paradigm provides insight into higher-order processing related to language comprehension and reasoning in healthy subjects. Future studies are needed to evaluate if our paradigm also proves sensitive for the detection of consciousness in non-responsive patients.

    We previously developed a molecular beacon-type probe to detect the strand scission in cellular base excision repair and found that the phosphodiester linkages in the fluorophore/quencher linkers were cleaved. This reaction was applied to a transfection reporter, which contained the unmodified phosphodiester in the linker to another type of fluorophore. After cotransfection of cells with the probe and the reporter, the signals were used to detect the incision and to confirm the proper transfection, respectively. This method will contribute to the prevention of false-negative results in experiments using molecular beacon-type probes. Copyright © 2013 Elsevier Inc. All rights reserved.

    We report on the selection of self-report measures for inclusion in the NIH Toolbox that are suitable for assessing the full range of negative affect including sadness, fear, and anger. The Toolbox is intended to serve as a "core battery" of assessment tools for cognition, sensation, motor function, and emotional health that will help to overcome the lack of consistency in measures used across epidemiological, observational, and intervention studies. A secondary goal of the NIH Toolbox is the identification of measures that are flexible, efficient, and precise, an agenda best fulfilled by the use of item banks calibrated with models from item response theory (IRT) and suitable for adaptive testing. Results from a sample of 1763 respondents supported use of the adult and pediatric item banks for emotional distress from the Patient-Reported Outcomes Measurement Information System (PROMIS(®)) as a starting point for capturing the full range of negative affect in healthy individuals. Content coverage for the adult Toolbox was also enhanced by the development of a scale for somatic arousal using items from the Mood and Anxiety Symptom Questionnaire (MASQ) and scales for hostility and physical aggression using items from the Buss-Perry Aggression Questionnaire (BPAQ).

  3. Negative affectivity: how serious a threat to self-report studies of psychological distress?

    1998-01-01

    Serious questions have been raised about the common practice of relying on self-report measures to assess the relation between subjective role experiences on the one hand and both mental and physical health symptoms on the other. Such self-report measures may reflect a common underlying dimension of negative affectivity (NA), thereby leading to spurious results. In this article, we present findings from analyses in which we estimate, using a hierarchical linear model, the relation between subjective experiences in job and marital roles and self-reports of symptoms of psychological distress after controlling for NA in a sample of 300 full-time employed men and women in married couples. Results demonstrate (a) that NA can account for a great deal of the variation in self-reported psychological distress, as much as half in the case of the men in the sample; (b) that estimates of the relations between a self-reported predictor of social-role quality (e.g., marital-role quality, job-role quality) may be biased by failure to include NA as a predictor of self-reported psychological distress; (c) that the degree of bias in these estimates is dependent on the nature of the predictor, and (d) that the role of NA as a confounder does not appear to be dependent on gender.

  4. Prefrontal electrical stimulation in nondepressed reduces levels of reported negative affects from daily stressors

    Full Text Available Negative emotional responses to the daily life stresses have cumulative effects which, in turn, impose wide-ranging negative constraints on emotional well being and neurocognitive performance (Kalueff et al, 2007, Charles et al, 2013, Nadler et al, 2010. Crucial cognitive functions such as memory and problem solving, as well more short term emotional responses (e.g., anticipation of- and response to- monetary rewards or losses are influenced by mood. The negative impact of these behavioural responses is felt at the individual level, but it also imposes major economic burden on modern healthcare systems. Although much research have been undertaken to understand the underlying mechanisms of depressed mood and design efficient treatment pathways, comparatively little was done to characterize mood modulations that remain within the boundaries of a healthy mental functioning. In one placebo-controlled experiments, we applied daily prefrontal transcranial Direct Current Stimulation (tDCS at five points in time, and found reliable improvements on self-reported mood evaluation. We replicated this finding in an independent double-blinded placebo-controlled experiment and showed that stimulation over a shorter period of time (3 days is sufficient to create detectable mood improvements. Taken together, our data show that repeated bilateral prefrontal tDCS can reduce psychological distress in nondepressed individuals.

    Research conducted during the last decades has provided increasing evidence for the use of psychological treatments for a number of psychiatric disorders and somatic complaints. However, by focusing only on the positive outcomes, less attention has been given to the potential of negative effects. Despite indications of deterioration and other adverse and unwanted events during treatment, little is known about their occurrence and characteristics. Hence, in order to facilitate research of negative effects, a new instrument for monitoring and reporting their incidence and impact was developed using a consensus among researchers, self-reports by patients, and a literature review: the Negative Effects Questionnaire. Participants were recruited via a smartphone-delivered self-help treatment for social anxiety disorder and through the media (N = 653). An exploratory factor analysis was performed, resulting in a six-factor solution with 32 items, accounting for 57.64% of the variance. The derived factors were: symptoms, quality, dependency, stigma, hopelessness, and failure. Items related to unpleasant memories, stress, and anxiety were experienced by more than one-third of the participants. Further, increased or novel symptoms, as well as lack of quality in the treatment and therapeutic relationship rendered the highest self-reported negative impact. In addition, the findings were discussed in relation to prior research and other similar instruments of adverse and unwanted events, giving credence to the items that are included. The instrument is presently available in eleven different languages and can be freely downloaded and used from www.neqscale.com.

    Full Text Available Quorum sensing signals are referred to as acylated homoserine lactones (AHL that are mainly found in Gram-negative bacteria. It implies the ability of certain bacteria of producing different AHL molecules. The bacteria Pseudomonas aureofaciens and Xenorhabdus nematophila were cultured in Luria-Bertani (LB10 media and CV026 was used as a reporter strain to detect the presence of AHLs produced by the cultured bacteria. In this study, the reporter strain has revealed the quorum sensing ability of P. aureofaciens and X. nematophila by producing the purple pigment violacein in the supply of external AHLs molecules. Thin layer chromatography (TLC bioassay having four controls was conducted to detect specific AHL molecule supplied by P. aureofaciens and X. nematophila. The specific AHL molecule was observed to be migrated according to their polarity on the TLC plate.

    '1he NASA Kennedy Space Center (KSC) and Air Force Eastern Range (ER) use data from two cloud-to-ground (CG) lightning detection networks, the CGLSS and the NLDN, and a volumetric lightning mapping array, LDAR, to monitor and characterize lightning that is potentially hazardous to ground or launch operations. Data obtained from these systems during June-August 2006 have been examined to check the classification of small, negative CGLSS reports that have an estimated peak current, [I(sup p)] less than 7 kA, and to determine the smallest values of I(sup p), that are produced by first strokes, by subsequent strokes that create a new ground contact (NGC), and by subsequent strokes that remain in a pre-existing channel (PEC). The results show that within 20 km of the KSC-ER, 21% of the low-amplitude negative CGLSS reports were produced by first strokes, with a minimum I(sup p) of-2.9 kA; 31% were by NGCs, with a minimum I(sup p) of-2.0 kA; and 14% were by PECs, with a minimum I(sup p) of -2.2 kA. The remaining 34% were produced by cloud pulses or lightning events that we were not able to classify.

    Full Text Available OBJECTIVE: In two studies, we aimed at further elucidating the relationship between trait negative affectivity (NA and habitual symptom reporting (HSR by relating these variables to measures of executive function, trait questionnaires, and effects of emotion induction. METHODS: Healthy female participants (N = 75 were selected on their scores for trait NA and for the Checklist for Symptoms in Daily Life. Three groups were compared: (1 low NA-low HSR; (2 high NA-low HSR; and (3 high NA-high HSR (low NA-high HSR did not occur. In study 1, participants underwent a Parametric Go/No-go Task and a Stroop Color-Word test, and trait questionnaires measured alexithymia and absorption. Forty-five participants (N = 15 in each group were further engaged in study 2 to induce state NA using an affective picture paradigm. RESULTS: Impaired inhibition on the Stroop and Go/No go Task characterized high trait NA, but not high HSR, whereas alexithymia and absorption were elevated in HSR, regardless of trait NA. Negative picture viewing induced elevated state NA in all groups, but only high HSR also reported more bodily symptoms. This effect was moderated, but not mediated by state NA. CONCLUSION: High trait NA is a vulnerability factor but not a sufficient condition to develop HSR. Deficient inhibition is related to the broad trait of NA, whereas the moderating effect of state NA on symptom reporting is specific for high HSR. Understanding processes related to alexithymia and absorption may specifically help to explain elevated HSR.

    Full Text Available Objective To investigate the origin, diagnosis, differential diagnosis, treatment, and prognosis of plasmablastic lymphoma (PBL. Methods Based on the retrospective analysis of the clinical data of two patients with PBL admitted to our department from 2009 to 2010, followed by a review of related literatures in China and abroad, we summarized our experience of the diagnosis and treatment of PBL. Results Two patients as reported in this paper were explicitly diagnosed to be HIV negative (–: one presented enlarged lymph nodes, whereas the other presented lesions in the ribs. Both displayed the same morphology characteristics of diffused large cell lymphoma. They also exhibited the typical plasma cell phenotype. Immunohistochemical analysis revealed that the cells stained positively for CD38, CD138, and CD79a, and stained poorly or even negatively for CD20 and PAX-5. PET-CT scans demonstrated that it involved several body parts, such as lymph nodes and bones. CHOP regime, ESHAP, IGVE, and other intensive treatment regimes showed no satisfactory effect. Relapse appeared quickly after a brief remission, and both patients died 2 and 7 months, respectively, after the diagnosis. Conclusions We can conclude that PBL is very rare, but with high malignancy and poor prognosis. PBL patients are of low sensitivity to chemotherapy drugs and exhibit short-time survival. There is no standard chemotherapy regimen for PBL.

    Wind farm developments have been hampered by claims that sound from wind turbines causes symptoms and negative health reports in nearby residents. As scientific reviews have failed to identify a plausible link between wind turbine sound and health effects, psychological expectations have been proposed as an explanation for health complaints. Building on recent work showing negative expectations can create symptoms from wind turbines, we investigated whether positive expectations can produce the opposite effect, in terms of a reduction in symptoms and improvements in reported health. 60 participants were randomized to either positive or negative expectation groups and subsequently exposed to audible wind farm sound and infrasound. Prior to exposure, negative expectation participants watched a DVD incorporating TV footage about health effects said to be caused by infrasound produced by wind turbines. In contrast, positive expectation participants viewed a DVD that outlined the possible therapeutic effects of infrasound exposure. During exposure to audible windfarm sound and infrasound, symptoms and mood were strongly influenced by the type of expectations. Negative expectation participants experienced a significant increase in symptoms and a significant deterioration in mood, while positive expectation participants reported a significant decrease in symptoms and a significant improvement in mood. The study demonstrates that expectations can influence symptom and mood reports in both positive and negative directions. The results suggest that if expectations about infrasound are framed in more neutral or benign ways, then it is likely reports of symptoms or negative effects could be nullified.

    Full Text Available Abstract Background Multicentric Castleman's disease (MCD is a rare disease, but is more frequent in AIDS patients. MCD has only been reported twice before in patients receiving immunosuppressive therapy after renal transplantation, and never in patients receiving immunosuppressive therapy without transplantation. About half of the cases of MCD are human herpesvirus 8 (HHV8 – related, in contrast to Kaposi's sarcoma, a more common complication arising after immunosuppression, where the virus is found in virtually all cases. Case presentation We report a HIV-1 negative, non-transplant patient who developed HHV8-associated multicentric Castleman's disease and Kaposi's sarcoma after 17 years of immunosuppressive treatment with cyclosporin A for a minimal change nephropathy. Chemotherapy with liposomal doxorubicin resolved both symptoms of multicentric Castleman's disease and Kaposi's sarcoma in this patient. A concomitant decline in the HHV8 viral load in serum/plasma, as determined by a quantitative real-time PCR assay, was observed. Conclusions Multicentric Castleman's disease can be a complication of cyclosporin A treatment. Both multicentric Castleman's disease and Kaposi's sarcoma in this patient were responsive to liposomal doxorubicin, the treatment of choice for Kaposi's sarcoma at the moment, again suggesting a common mechanism linking both disorders, at least for HHV8-positive multicentric Castleman's disease and Kaposi's sarcoma. HHV8 viral load measurements can be used to monitor effectiveness of therapy.

    The natural killer (NK) cell activating receptor NKp46/NCR1 plays a critical role in elimination of virus-infected and tumor cells. The NCR1 gene can be transcribed into five different splice variants, but the functional importance and physiological distribution of NKp46 isoforms are not yet fully understood. Here, we shed light on differential expression of NKp46 splice variants in viral respiratory tract infections and their functional difference at the cellular level. NKp46 was the most predominantly expressed natural cytotoxicity receptor in the nasal lavage of patients infected with four respiratory viruses: respiratory syncytia virus, adenovirus, human metapneumovirus, or influenza A. Expression of NKp30 was far lower and NKp44 was absent in all patients. Domain 1-negative NKp46 splice variants (i.e., NKp46 isoform d) were the predominantly expressed isoform in nasal lavage following viral infections. Using our unique anti-NKp46 mAb, D2-9A5, which recognizes the D2 extracellular domain, and a commercial anti-NKp46 mAb, 9E2, which recognizes D1 domain, allowed us to identify a small subset of NKp46 D1-negative splice variant-expressing cells within cultured human primary NK cells. This NKp46 D1-negative subset also showed higher degranulation efficiency in term of CD107a surface expression. NK-92 cell lines expressing NKp46 D1-negative and NKp46 D1-positive splice variants also showed functional differences when interacting with targets. A NKp46 D1-negative isoform-expressing NK-92 cell line showed enhanced degranulation activity. To our knowledge, we provide the first evidence showing the physiological distribution and functional importance of human NKp46 splice variants under pathological conditions. PMID:28261217

  5. Generalized Anxiety Disorder and Social Anxiety Disorder, but Not Panic Anxiety Disorder, Are Associated with Higher Sensitivity to Learning from Negative Feedback: Behavioral and Computational Investigation.

    Anxiety disorders, including generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic anxiety disorder (PAD), are a group of common psychiatric conditions. They are characterized by excessive worrying, uneasiness, and fear of future events, such that they affect social and occupational functioning. Anxiety disorders can alter behavior and cognition as well, yet little is known about the particular domains they affect. In this study, we tested the cognitive correlates of medication-free patients with GAD, SAD, and PAD, along with matched healthy participants using a probabilistic category-learning task that allows the dissociation between positive and negative feedback learning. We also fitted all participants' data to a Q-learning model and various actor-critic models that examine learning rate parameters from positive and negative feedback to investigate effects of valence vs. action on performance. SAD and GAD patients were more sensitive to negative feedback than either PAD patients or healthy participants. PAD, SAD, and GAD patients did not differ in positive-feedback learning compared to healthy participants. We found that Q-learning models provide the simplest fit of the data in comparison to other models. However, computational analysis revealed that groups did not differ in terms of learning rate or exploration values. These findings argue that (a) not all anxiety spectrum disorders share similar cognitive correlates, but are rather different in ways that do not link them to the hallmark of anxiety (higher sensitivity to negative feedback); and (b) perception of negative consequences is the core feature of GAD and SAD, but not PAD. Further research is needed to examine the similarities and differences between anxiety spectrum disorders in other cognitive domains and potential implementation of behavioral therapy to remediate cognitive deficits.

    Guaiac-based fecal occult blood tests (gFOBTs) are the most commonly applied tests for colorectal cancer screening globally but have relatively poor sensitivity to detect colorectal neoplasms. Men have higher prevalences of colorectal neoplasms than women. In case of a positive gFOBT result, participants are referred to colonoscopy, independent of sex. To assess performance of gFOBT in routine screening practice, we assessed age and sex specific prevalences (age groups: 55-59, 60-64, 65-69 and 70-74) of colorectal neoplasms in 182,956 women and men undergoing colonoscopy for primary screening and in 20,884 women and men undergoing colonoscopy to follow-up a positive gFOBT in Bavaria, Germany, in 2007-2009. We conducted model calculations to estimate prevalences among gFOBT negative individuals. Analogous model calculations were performed for women and men tested positive or negative with fecal immunochemical tests. In all age groups (55-59, 60-64, 65-69 and 70-74 years), men undergoing colonoscopy for primary screening had substantially higher prevalences of any colorectal neoplasms and essentially the same prevalences of advanced colorectal neoplasms compared to women undergoing colonoscopy to follow-up a positive gFOBT. Model calculations suggest that men with negative gFOBT likewise have substantially higher prevalences of colorectal neoplasms than gFOBT positive women in each age group. Model calculations further indicate that no such sex paradoxon occurs, and a much clearer risk stratification can be achieved with fecal immunochemical tests. Our findings underline need to move forward from and overcome shortcomings of gFOBT-based colorectal cancer screening. © 2013 UICC.

  7. Classification of Small Negative Lightning Reports at the KSC-ER

    Ward, Jennifer G.; Cummins, Kenneth L.; Krider, Philip

    2008-01-01

    The NASA Kennedy Space Center (KSC) and Air Force Eastern Range (ER) operate an extensive suite of lightning sensors because Florida experiences the highest area density of ground strikes in the United States, with area densities approaching 16 fl/sq km/yr when accumulated in 10x10 km (100 sq km) grids. The KSC-ER use data derived from two cloud-to-ground (CG) lightning detection networks, the "Cloud-to-Ground Lightning Surveillance System" (CGLSS) and the U.S. National Lightning Detection Network (TradeMark) (NLDN) plus a 3-dimensional lightning mapping system, the Lightning Detection and Ranging (LDAR) system, to provide warnings for ground operations and to insure mission safety during space launches. For operational applications at the KSC-ER it is important to understand the performance of each lightning detection system in considerable detail. In this work we examine a specific subset of the CGLSS stroke reports that have low values of the negative inferred peak current, Ip, i.e. values between 0 and -7 kA, and were thought to produce a new ground contact (NGC). When possible, the NLDN and LDAR systems were used to validate the CGLSS classification and to determine how many of these reported strokes were first strokes, subsequent strokes in a pre-existing channel (PEC), or cloud pulses that the CGLSS misclassified as CG strokes. It is scientifically important to determine the smallest current that can reach the ground either in the form of a first stroke or by way of a subsequent stroke that creates a new ground contact. In Biagi et al (2007), 52 low amplitude, negative return strokes ([Ip] strokes) on the basis of video and waveform recordings. Low amplitude return strokes are interesting because they are usually difficult to detect, and they are thought to bypass conventional lightning protection that relies on a sufficient attractive radius to prevent "shielding failure" (Golde, 1977). They also have larger location errors compared to the larger current

    . Several unusual structural features were detected. Multiple G X A pairings in two of the putative helices, which are compatible with phylogenetic sequence comparisons, are strongly supported by the occurrence of cobra venom ribonuclease cuts adjacent to, and in one case between, these pairings. Evidence......An experimental approach was used to determine and compare the highest order structure within the 150 to 200 nucleotides at the 3'-ends of the RNAs from the small ribosomal subunits of Escherichia coli, Bacillus stearothermophilus and Saccharomyces cerevisiae. Chemical reagents were employed...... of additional higher order structure in the renatured free RNA.

    This paper presents a case report of an HIV-negative, supraglottic Kaposi's sarcoma patient. The 80-year-old male patient was admitted with complaints of hoarseness, difficulty in swallowing, and a stinging sensation in his throat for approximately six months. The endoscopic larynx examination revealed a lesion which had completely infiltrated the epiglottis, reached right aryepiglottic fold, was vegetating, pink and purple in color, multilobular, fragile, and shaped like a bunch of grapes, and partially blocked the bleeding airway passage. The case was discussed by the hospital's head-neck cancer committee and a surgery decision was made. A tracheotomy was performed under local anesthesia before the operation due to respiratory distress and endotracheal intubation difficulty. Direct laryngoscopy showed that the mass was limited in the supraglottic area, had invaded the entire left aryepiglottic fold and one-third of the front right aryepiglottic fold, and completely covered epiglottis. It should be remembered that although rare, Kaposi's sarcoma may be encountered in larynx malignancy cases. Disease-free survival may be achieved through local excision and postoperative radiotherapy. PMID:27375914

It should be remembered that although rare, Kaposi’s sarcoma may be encountered in larynx malignancy cases. Disease-free survival may be achieved through local excision and postoperative radiotherapy.

    To compare abnormal vaginal colonization between natural pregnancy and pregnancy by infertility treatment in high-risk parturient women and to examine the association between abnormal vaginal colonization and early-onset neonatal sepsis (EONS). The clinical characteristics, vaginal culture result, and delivery outcome of patients who admitted to our high-risk unit between 2005 and 2014 were retrospectively reviewed and compared. We investigated the prevalence of EONS according to maternal vaginal colonization and examined the concordance between maternal vaginal bacteria and etiologic microorganism causing EONS. Among 1096 pregnancies, the rate of vaginal colonization by gram-negative bacteria, especially Escherichia coli was significantly higher in pregnancies by infertility treatment after adjustment of confounding variables (E. coli, OR [95% CI]: 2.47 [1.33-4.57], p = 0.004). The rate of EONS was significantly higher in neonates with maternal abnormal vaginal bacteria colonization (OR [95% CI]: 3.38 [1.44-7.93], p = 0.005) after adjusting for confounding variables. Notably, among microorganisms isolated from maternal vagina, E. coli and Staphylococcus aureus were consistent with the results from neonatal blood culture in EONS. Our data implicate a possible association between gram-negative bacteria colonization and infertility treatment and suggest that maternal vaginal colonization may be associated with EONS of neonates in high-risk pregnancy.

    Antinuclear antibody (ANA) negative lupus is an important subset of the systemic lupus erythematosus (SLE) disease spectrum. Since the introduction of human cell line for ANA assay, the occurrence of true ANA-negative SLE has been a rare clinical phenomenon. The nature of cardiac involvement in ANA-negative SLE is not well understood, although any cardiac involvement, including valvular dysfunction, should be considered as a presenting manifestation of SLE irrespective of serology status. Early recognition and intervention appears to be associated with decreased morbidity. The following report describes our first case of ANA-negative SLE with an initial presentation of severe cardiac valvular dysfunction and heart failure. It also characterizes the spectrum of disease severity in ANA-negative SLE and demonstrates how aggressive SLE therapy can improve cardiac disease.

    Negative energy balance during military operations can be severe and result in significant reductions in fat-free mass (FFM). Consuming supplemental high-quality protein following such military operations may accelerate restoration of FFM. Body composition (dual-energy X-ray absorptiometry) and whole body protein turnover (single-pool [(15)N]alanine method) were determined before (PRE) and after 7 days (POST) of severe negative energy balance during military training in 63 male US Marines (means ± SD, 25 ± 3 yr, 84 ± 9 kg). After POST measures were collected, volunteers were randomized to receive higher protein (HIGH: 1,103 kcal/day, 133 g protein/day), moderate protein (MOD: 974 kcal/day, 84 g protein/day), or carbohydrate-based low protein control (CON: 1,042 kcal/day, 7 g protein/day) supplements, in addition to a self-selected, ad libitum diet, for the 27-day intervention (REFED). Measurements were repeated POST-REFED. POST total body mass (TBM; -5.8 ± 1.0 kg, -7.0%), FFM (-3.1 ± 1.6 kg, -4.7%), and net protein balance (-1.7 ± 1.1 g protein·kg(-1)·day(-1)) were lower and proteolysis (1.1 ± 1.9 g protein·kg(-1)·day(-1)) was higher compared with PRE (P balance (0.4 ± 1.0 g protein·kg(-1)·day(-1)) and gained TBM (5.9 ± 1.7 kg, 7.8%) and FFM (3.6 ± 1.8 kg, 5.7%) POST-REFED compared with POST (P balance.NEW & NOTEWORTHY This article demonstrates 1) the majority of physiological decrements incurred during military training (e.g., total and fat-free mass loss), with the exception of net protein balance, resolve and return to pretraining values after 27 days and 2) protein supplementation, in addition to an ad libitum, higher protein (~2.0 g·kg(-1)·day(-1)), energy adequate diet, is not necessary to restore fat-free mass following short-term severe negative energy balance.

    A 32 year old Indian female was referred to our hospital at 32 weeks of gestation because of difficulty in blood group determination and further antenatal care. The results of cell and serum grouping of her blood sample were suggestive of Bombay (O(h)) Rh (D) negative phenotype. An indirect antiglobulin test (IAT) using a pool of red cells from two Bombay Rh (D) positive blood donors gave negative result using the tube as well as the gel technique (LISS-Coombs Card, BioRad, Switzerland), thus ruling out anti-D antibody in her serum. The anti-H titer was 16 (tube technique) and with dithiothreitol (DTT) treated patient's serum the antibody screening was negative suggestive of IgM type of anti-H antibodies. Within the patient's family, only one member (younger sister) was of O(h) phenotype and also was Rh (D) negative. The baby was born vaginally at 38+6 weeks of gestation and was non-hydropic with a packed cell volume (PCV) of 55%. The baby's blood group was AB Rh (D) negative and the cord blood direct antiglobulin test (DAT) was negative. Thus, a careful serological testing of O(h) phenotype antenatal women especially with Rh (D) negative phenotype is of utmost importance in determining the isoimmunization status.

    Cannabis use is frequent among depressed patients and may lead to the so-called "amotivational syndrome", which combines symptoms of affective flattening and loss of emotional reactivity (i.e. the so-called "negative" symptomatology). The aim of this study was to investigate the negative symptomatology in depressed patients with concomitant cannabis use disorders (CUDs) in comparison with depressed patients without CUDs. Fifty-one patients with a diagnosis of Major Depressive Disorder (MDD) and concomitant CUD and fifty-one MDD patients were enrolled in the study. The 21-Item Hamilton Depression Rating Scale (HDRS) and the negative symptoms subscales of the Positive and Negative Syndrome Scale (PANSS) were used to assess depressive and negative symptomatology. Patients with cannabis use disorders presented significantly more severe negative symptoms in comparison with patients without cannabis use (15.18 ± 2.25 vs 13.75 ± 2.44; t100 = 3.25 p = 0.002). A deeper knowledge of the "negative" psychopathological profile of MDD patients who use cannabis may lead to novel etiopathogenetic models of MDD and to more appropriate treatment approaches.

    Postoperative negative pressure pulmonary edema (NPPE) is a rare, but well-known life-threatening complication of acute upper airway obstruction (UAO) which develops after general anesthesia. The pronounced inspiratory efforts following UAO lead to excessive negative inspiratory pressure, which may cause acute pulmonary edema. Early recognition and prompt treatment of NPPE is necessary to prevent patient morbidity and mortality. In addition, the physician should carefully manage the patient who has risk factors of UAO to prevent this situation. We experienced a case of NPPE following laryngospasm after tracheal extubation in an obese patient who underwent open reduction of orbital wall and nasal bone surgery. PMID:26316826

    Learning theories of depression have proposed that depressive cognitions, such as negative thoughts with reference to oneself, can develop through a reinforcement learning mechanism. This negative self-reference is considered to be positively reinforced by rewarding experiences such as genuine support from others after negative self-disclosure, and negatively reinforced by avoidance of potential aversive situations. The learning account additionally predicts that negative self-reference would be maintained by an inability to adjust one’s behavior when negative self-reference no longer leads to such reward. To test this prediction, we designed an adapted version of the reversal-learning task. In this task, participants were reinforced to choose and engage in either negative or positive self-reference by probabilistic economic reward and punishment. Although participants were initially trained to choose negative self-reference, the stimulus-reward contingencies were reversed to prompt a shift toward positive self-reference (Study 1) and a further shift toward negative self-reference (Study 2). Model-based computational analyses showed that depressive symptoms were associated with a low learning rate of negative self-reference, indicating a high level of reward expectancy for negative self-reference even after the contingency reversal. Furthermore, the difficulty in updating outcome predictions of negative self-reference was significantly associated with the extent to which one possesses negative self-images. These results suggest that difficulty in adjusting action-outcome estimates for negative self-reference increases the chance to be faced with negative aspects of self, which may result in depressive symptoms.

    2007-01-01

    Spina bifida is a developmental defect in the vertebral column, in which the laminae fail to fuse and thereby the spinal cord is relatively unprotected. We report a case of spina bifida, in a dried specimen of sacrum, characterized by a prominent S1 spine and a higher sacral hiatus. Conventional textbooks of anatomy provide less information about the clinical implications of such anomalies and research studies are the only source of information. The present study, discusses in detail, the structural and radiological aspects of spina bifida, with a higher sacral hiatus. Precise knowledge of normal and abnormal anatomy of the sacrum may be clinically important for anesthetists, neurologists, radiologists and orthopedic surgeons, in their clinical practice (Fig. 3, Ref. 16).

    Full Text Available Cervical regional nodal involvement, as the first manifestation of prostatic cancer, has been rarely reported. Prostate cancer metastasis to the supraclavicular lymph nodes with negative immunohistochemical stain of PSA is even rarer. We report a case of prostate cancer with negative immunohistochemical stain of prostate-specific antigen presenting with left supraclavicular node enlargement. A 63-year-old man was referred to our hospital for a left supraclavicular mass. He had a family history of gastric cancer (two brothers had died of gastric cancer. Enhanced computed tomography of the abdomen revealed retroperitoneal lymph node enlargement. Gastroscopy revealed no evidence of any gastric tumor. Biopsy of the left-sided supraclavicular lymph nodes revealed metastatic adenocarcinoma with a negative prostate-specific antigen (PSA stain. The serum tumor markers were examined, revealing PSA levels of 21.820 ng/ml. Biopsy of the prostate disclosed poorly-to-moderately differentiated adenocarcinoma (Gleason 4 + 4 = 8. Although rare, prostate cancer should be considered in the differential diagnoses of elderly men with undetermined original adenocarcinoma, metastatic to the supraclavicular lymph nodes. Rectal examination, serum PSA and pelvic image can be helpful to lead the diagnosis. PSA stain may be weak or negative in some poorly differentiated patients, however, it is still a sensitive and specific marker of prostatic differentiation and must be routinely applied.

    Globally, the rate at which maternal overweight and obesity increase with rising wealth is higher than the accompanying decline in the prevalence of child stunting, resulting in the double burden of malnutrition. The positive association between household wealth and child linear growth is larger in households with a more educated mother. However, whether a similar positive and synergistic association between maternal education and household wealth is observed for maternal body weight is unknown. Our objective was to assess the potential protective role of maternal education in the etiology of the double burden of malnutrition (stunted child with an overweight mother). We used data on 1547 nonpregnant mothers (aged 18-49 y) and their children (aged 0-5 y) collected in a cross-sectional survey in 235 rural communities in southern Mexico. Child height-for-age Z-score and maternal body weight were regressed on household wealth, women's schooling, and the interaction between both, controlling for relevant covariates. A similar model was used for the prevalence of double-burden pairs (stunted child with an overweight mother). In mothers with less than primary school, a doubling in wealth was not associated with improved child's height but was associated with an increase in mother's weight (3.7%, P effectively mitigated the negative effects of household wealth on the prevalence of double-burden households in rural Mexico. Where maternal schooling is low, poverty reduction must be accompanied by effective behavior change communication to prevent child stunting and to protect women from unhealthy weight gain.

    2014-04-01

    Full Text Available Cryptococcus spp. cerebral abscesses are uncommon in immunocompetent subjects. The recommended induction treatment is the administration of amphotericin B plus flucytosine combined with resection for lesions ≥3cm. In this paper, we describe an HIV-negative woman diagnosed with a large cryptococcoma in the immediate postpartum period. The lesion was not resected, and due to amphotericin B intolerance, she received an extended course of fluconazole monotherapy. There was no disease recurrence during the 4 years of follow-up. The abrupt onset of her symptoms following delivery suggests that she developed a postpartum immune reconstitution syndrome. This case also demonstrates that in specific situations fluconazole monotherapy can be attempted in immunocompetent patients with cryptococcoma.

    Single photon absorption-single electron detachment from few-electron atomic negative ions was studied. A crossed beam apparatus is being used to perform energy- and angle-resolved photoelectron spectroscopic measurements following photodetachment. Forward-directed electrons were collected and energy analyzed. The kinetic energies and yields of the photoelectrons were obtained by fitting the spectral peaks to Gaussian functions. Electron affinities, asymmetry parameters and cross sections are determined from these measurements. A ratio method in which the cross section for the ion of interest is measured relative to that of a reference ion was used. The study of the photodetachment of Li{sup {minus}} was completed, and attention has turned to the photodetachment of the stable ion B{sup {minus}} and the metastable ion Be{sup {minus}}.

    A siphon is suggested to support cerebral blood flow but appears not to be established because internal jugular venous (IJV) pressure is close to zero in upright humans. Thus, in eleven young healthy males, IJV pressure was 9 ± 1 mmHg (mean ± SE) when supine and fell to 3 ± 1 mmHg when seated......, and middle cerebral artery mean blood velocity (MCA Vmean; P ... MCA Vmean decreased and yet within the time of observation ScO2 was not necessarily affected. These findings support the hypothesis that a negative IJV pressure that is a prerequisite for creation of a siphon provokes venous collapse inside the dura, and thereby limits rather than supports CBF....

    Alterations in the sequestration and destruction of bacteria were studied after 10 days of biliary obstruction. Intraperitoneal injection of radiolabeled Escherichia coli was used to study bacterial localization in rats 10 days after common duct ligation and transection or sham celiotomy. Animals were sacrificed 4 hours later and uptake by liver, spleen, lung, and kidney were studied with a scintillation counter. No significant difference in localization between the two groups was noted. Bacteremia was induced in a second set of animals and quantitative bacterial organ cultures were performed. Significantly more viable organisms were identified in lung, liver, and kidney of animals that underwent common duct ligation and transection, when compared with controls that underwent sham celiotomy. This suggests that there is a defect in bacterial killing after 10 days of biliary obstruction. The inability to effectively clear and kill gram-negative bacteria in patients with biliary obstruction may account for some of the clinical complications seen in this patient population.

    Full Text Available Abstract Background In the present article, we propose an alternative method for dealing with negative affectivity (NA biases in research, while investigating the association between a deleterious psychosocial environment at work and poor mental health. First, we investigated how strong NA must be to cause an observed correlation between the independent and dependent variables. Second, we subjectively assessed whether NA can have a large enough impact on a large enough number of subjects to invalidate the observed correlations between dependent and independent variables. Methods We simulated 10,000 populations of 300 subjects each, using the marginal distribution of workers in an actual population that had answered the Siegrist's questionnaire on effort and reward imbalance (ERI and the General Health Questionnaire (GHQ. Results The results of the present study suggested that simulated NA has a minimal effect on the mean scores for effort and reward. However, the correlations between the effort and reward imbalance (ERI ratio and the GHQ score might be important, even in simulated populations with a limited NA. Conclusions When investigating the relationship between the ERI ratio and the GHQ score, we suggest the following rules for the interpretation of the results: correlations with an explained variance of 5% and below should be considered with caution; correlations with an explained variance between 5% and 10% may result from NA, although this effect does not seem likely; and correlations with an explained variance of 10% and above are not likely to be the result of NA biases.

    Full Text Available Plasmablastic lymphoma is a rare and aggressive lymphoma characterized by the diffuse proliferation of large neoplastic cells resembling immunoblasts with an immunophenotype of plasma cells. A 47-year-old male was referred to our hospital with gastrointestinal bleeding, and a mass 10 cm in diameter, was detected. An endoscopic biopsy was performed subsequently. Histopathological examination of the biopsy material revealed ulcer, alterations associated with ulcer, and further presented a diffuse infiltration of atypical cells with abundant cytoplasm and pleomorphic nuclei, some with crush artifacts in lamina propria. Immunohistochemically, the tumor cells were negative for cytokeratin, CD2, CD20, and PAX5; but they were positive for CD3, MUM1, CD38 and CD138. Ki67 proliferation index was as high as 95%. The case was signed out as CD3-positive plasmablastic lymphoma with clinical, histopathological and immunohisto-chemical findings. The plasmablastic lymphoma case with an aberrant CD3 expression has been presented here, which is rarely observed in stomach.

    Laryngospasm, an occlusion of the glottis, can occur at any time during anesthesia, and is associated with serious perioperative complications such as hypoxia, hypercabia, aspiration, bronchospasm, arrhythmia, prolonged recovery, cardiac collapse, and eventually catastrophic death. Importantly, postoperative negative pressure pulmonary edema (NPPE) is a rare, but well described life-threatening complication related to acute and chronic upper airway obstruction. Sugammadex well known for affirmatively reducing the postoperative pulmonary complications associated with residual neuromuscular blockade may have an indirect role in triggering the negative intrathoracic pressure by raising a rapid and efficacious respiratory muscle strength in acute upper airway obstruction. Herein, we report a case of postoperative NPPE following repetitive laryngospasm even after reversal of rocuronium-induced neuromuscular blockade using sugammadex.

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, characterized by an autoantibody response to various nuclear and cytoplasmic antigens. Renal disease in SLE occurs in 40-75% of patients, most often within five years of onset of disease, and is one of the strongest predictors of a poor outcome. A hallmark of glomerular involvement in lupus nephritis is the presence of autoantibodies against double-stranded DNA (dsDNA). Its level usually correlates with disease activity. Our patient presented with a rash resembling malar rash and features of nephrotic syndrome. On investigating, patient was found to have pancytopenia, raised erythrocyte sedimentation rate and depressed serum C3 levels with positivity of antinuclear antibodies and anti- Ro antibodies. However, most of the markers of lupus nephritis including anti dsDNA antibody were negative. Renal biopsy showed features of lupus nephritis (class-IV). Differential item functioning studies showed a full house immunoflourescence staining pattern characteristic of lupus nephritis. Association of Anti-Ro antibody alone with lupus nephritis is less known in literature. Negativity of anti-dsDNA antibody, which is usually considered to be diagnostic of lupus nephritis, poses a diagnostic dilemma short of renal biopsy. Till date only very few cases of non-drug induced lupus nephritis with negative dsDNA antibodies have been reported. In this report we wish to highlight a case of lupus nephritis which was negative for its specific anti dsDNA antibodies and with possible role of anti-Ro antibodies in the pathogenesis of lupus nephritis although the underlying mechanism is incompletely understood.

    After a long history of privileging psychosexual etiological factors over pain and physiological processes, dyspareunia has enjoyed 1 decade of pointed research focused on the presenting problem of pain. Although it is generally acknowledged that certain affective and cognitive styles may play a role in an individual's experience of pain in general, investigations into these questions specifically as they pertain to pain that occurs during sex are relatively scarce. To add to this growing body of knowledge, 759 women aged 18 to 29 completed questionnaires about current sexual functioning, gynecologic history, expectations about intercourse, and various personality and health-related anxiety measures. One-hundred-one women (14% of the sample) reported pain during intercourse on at least 50% of attempts. This group of women significantly differed from 536 women reporting pain on less than 10% of intercourse attempts on personality constructs related to emotional and relational well-being (e.g., neuroticism, extraversion, agreeableness), as well as anxiety sensitivity, anxiety related to physical health concerns, and the amplification of somatosensory experiences. This affective and cognitive profile is consistent with previous studies that have found an attentional hypervigilance to health and pain-related information in women with dyspareunia, all of which could prove germane to cognitive-behavioral treatments targeting this disorder.

    Experiments are reported in which a methane plasma is created, and the methyl ions and hydrogen ions are accelerated within a microchannel array so that they interact with neutral methane molecules on the inside surfaces of the microchannels. No catalysts are used, and the device operates at room temperature. Impact energies of the ions are in the range of 10 eV to greater than 100 eV, and the energy delivered in the interaction at the surfaces causes the production of larger hydrocarbon molecules, such as C{sub 2}H{sub 2}, C{sub 2}H{sub 4}, and C{sub 2}H{sub 6}, along with C{sub 3}, C{sub 4}, C{sub 5}m C{sub 6}, C{sub 7}m and C{sub 8} molecules. There is a decreasing percentage of larger molecules produced, in comparison with the C{sub 2} and C{sub 3} types. Conversion effectiveness is greater at higher pressure, due to the increased ionic activity. The yield of the higher hydrocarbons depends upon the external voltage used, and voltage can be used as a control parameter to adjust the output mixture proportions. A conversion energy of 2.59 kilowatt hours/killogram of output has been demonstrated, and a reduction of this by a factor of 10 is possible using known techniques. In batch experiments, the selectivity for C{sub 2} has varied from 47% to 88%, and selectivity for C{sub 6} has ranged from 0% to 12.8%. Other hydrocarbon selectivities also span a wide and useful range. The estimated costs for hydrocarbons produced with this technology are in the range of $200 per tonne, in production quantities, depending upon natural gas costs. Pilot production experiments are recommended to make these estimates more precise, and to address strategies for scaling the technology up to production levels. Applications are discussed.

    2016-06-15

    Femoral neck stress fracture (FNSF) is well documented in the orthopedic literature and is generally associated with strenuous activities such as long-distance running and military training. The diagnostic yield of magnetic resonance imaging (MRI) for FNSF was reported to be 100 %, and early MRI is recommended when this fracture is suspected. We encountered a 16-year-old male long-distance runner with FNSF in whom the left femoral neck showed no signal changes on MRI although an effusion was detected in the left hip joint. One month later, roentgenograms revealed periosteal callus and oblique consolidation of the left femoral neck, confirming the diagnosis of compression FNSF. Because FNSF with a normal bone marrow signal on MRI is very rare, this patient is presented here. (orig.)

    This case report highlights the presentation of syphilis in a small-for-gestational age (SGA) female infant who was born to a mother with no prenatal care. In the first 2 days of life, the infant developed hepatosplenomegaly, conjugated hyperbilirubinemia, thrombocytopenia, and hemolysis. After extensive diagnostic investigation, the case was solved on the infant's day of life (DOL) 12. In retrospect, the health care team had obtained a diagnostic result that could potentially have solved the case on DOL 2. Although this infant suffered no long-term sequelae secondary to the delayed diagnosis, the review of this case presentation may assist other clinicians in an early identification of a potentially lethal diagnosis.

    2014-10-01

    The current study investigated relationships among self-reported peer victimization, suicidality, and depression in adolescent psychiatric inpatients. Sixty-seven adolescent psychiatric inpatients at a Midwestern children's hospital completed measures of bullying and peer victimization, suicidal ideation, and depression during their inpatient stay. Analyses indicated significant moderate correlations among victimization, suicidal ideation, and depression in adolescents. Results from mediational analyses found that negative self-esteem mediated the relationship between peer victimization and suicidal ideation. To date, this study is the first to directly examine the mechanisms underlying the relationship between peer victimization and suicidal ideation in adolescent psychiatric inpatients.

    Full Text Available Government policy and institutional initiatives have influenced increases in enrolment of non-traditional students to Australian universities. For these students, university culture is often incongruent with their own, making it difficult to understand the tacit requirements for participation and success. Academic teaching staff are important in creating socially inclusive learning experiences, particularly in first year subjects. This paper presents an institution-wide approach to enhancing socially inclusive teaching at one Australian university. Underpinned by a framework of ”bridging social-incongruity” the initiative was guided by six principles of socially inclusive teaching to support practice as proposed in the 2012 “Effective support of students from low socioeconomic backgrounds in higher education” report commissioned by the Australian Office of Learning and Teaching. Feedback from 150 academic teaching staff from various disciplines and campus locations, suggests this initiative was effective in increasing understanding of socially inclusive teaching practices with many participants indicating the teaching enhancements were applicable for their teaching context.

  18. The content of lexical stimuli and self-reported physiological state modulate error-related negativity amplitude.

    Science.gov (United States)

    Benau, Erik M; Moelter, Stephen T

    2016-09-01

    The Error-Related Negativity (ERN) and Correct-Response Negativity (CRN) are brief event-related potential (ERP) components-elicited after the commission of a response-associated with motivation, emotion, and affect. The Error Positivity (Pe) typically appears after the ERN, and corresponds to awareness of having committed an error. Although motivation has long been established as an important factor in the expression and morphology of the ERN, physiological state has rarely been explored as a variable in these investigations. In the present study, we investigated whether self-reported physiological state (SRPS; wakefulness, hunger, or thirst) corresponds with ERN amplitude and type of lexical stimuli. Participants completed a SRPS questionnaire and then completed a speeded Lexical Decision Task with words and pseudowords that were either food-related or neutral. Though similar in frequency and length, food-related stimuli elicited increased accuracy, faster errors, and generated a larger ERN and smaller CRN than neutral words. Self-reported thirst correlated with improved accuracy and smaller ERN and CRN amplitudes. The Pe and Pc (correct positivity) were not impacted by physiological state or by stimulus content. The results indicate that physiological state and manipulations of lexical content may serve as important avenues for future research. Future studies that apply more sensitive measures of physiological and motivational state (e.g., biomarkers for satiety) or direct manipulations of satiety may be a useful technique for future research into response monitoring.

    Negative affectivity is a personality trait that predisposes people to psychological distress and low life satisfaction. Negative affectivity may also affect pain intensity and physical function in patients with musculoskeletal conditions. We explored the association of negative affectivity to pain intensity and self-reported physical function, and tested whether pain intensity mediates the effect of negative affectivity on physical function. In a cross-sectional study, 102 patients with upper extremity musculoskeletal conditions presenting to an orthopedic surgeon completed self-report measures of negative affectivity, pain intensity, and physical function in addition to demographic and injury information. We used the Preacher and Hayes' bootstrapping approach to quantify the indirect effect of negative affectivity on physical function through pain intensity. Negative affectivity correlated with greater pain intensity and lower self-reported physical function significantly. Also, pain intensity mediated the association of negative affectivity with physical function. The indirect effect accounted for one-third of the total effect. To conclude, negative affectivity is associated with decreased engagement in daily life activities both directly, but also indirectly through increased pain intensity. Treatments targeting negative affectivity may be more economical and efficient for alleviation of pain and limitations associated with musculoskeletal illness than those addressing coping strategies or psychological distress.

    Energy Technology Data Exchange (ETDEWEB)

    Kvale, T.J.

    1993-05-01

    This Technical Progress Report describes the progress made on the research objectives during the past twelve months. This research project is designed to provide measurements of various scattering processes which occur in H{sup {minus}} collisions with atomic (specifically, noble gas and atomic hydrogen) targets at intermediate energies. These processes include elastic scattering, single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H{sup {minus}} is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements in progress will provide either experimentally determined cross sections or set upper limits to those cross sections. In either case, these measurements will be stringent tests of our understanding in energetic negative ion - atom collisions. In addition secondary negative particle emission yields for H{sup 0} on Cu in the 3 to 50 keV range are shown.

    Syphilis has a broad spectrum of clinical manifestations, and the cerebral gumma is a kind of neurosyphilis which is rare and can be cured by appropriate antibiotic treatments. However, in clinical practices, diagnosis of cerebral syphilitic gumma is often difficult because imaging and laboratory findings revealed elusive results. Herein, we present a rare case of neurosyphilis presenting as cerebral gumma confirmed by histopathological examination, and positive serologic and cerebrospinal fluid analyses. This case report suggests that cerebral gumma should be considered as possible diagnosis for human immunodeficiency virus-negative patients with space-occupying lesion of the brain. And this case also provides importance of clinical suspicions in diagnosing neurosyphilis because syphilis serology is not routinely tested on patients with neurologic symptoms.

  8. Injuries, negative consequences, and risk behaviors among both injured and uninjured emergency department patients who report using alcohol and marijuana

    Directory of Open Access Journals (Sweden)

    Woolard Robert

    2009-01-01

    Full Text Available Background: Brief intervention (BI to reduce hazardous drinking and negative consequences such as injury has been effective when given in the emergency department (ED. The effectiveness and effect of BI has varied between injured and uninjured ED patients. This study compares injured and uninjured ED patients who admit to alcohol and marijuana use to determine their need and their readiness for BI. Patients and Methods: Participants volunteered to enter a randomized controlled trial of BI to reduce hazardous alcohol and marijuana use. Adult ED patients who had had alcohol in the last month and smoked marijuana in the last year were recruited. Those patients who were admitted to hospital, were under police custody, or were seeking treatment for substance use or psychiatric disorder were excluded. Research assistants interviewed participants using a validated questionnaire. Data were analyzed using SAS (version 9.1. Binominal tests of proportions, t-test analyses, and transformations were conducted as appropriate. Results: Injured (n = 249 and uninjured (n = 266 study participants reported very high, statistically equivalent (P > 0.05, rates of binge drinking (4-5 days/month, marijuana use (13 days/month, driving under the influence of marijuana or alcohol (>49% in the last 3 months, injury (>83% in the last year, and other negative consequences (>64% in the last 3 months prior to their ED visit. These behaviors and the consequences demonstrate a need for change. Both injured and uninjured subjects were ready to change (>56% and confident they could change (>91% alcohol and marijuana use. Discussion: ED patients who admit to alcohol and marijuana use also use other hazardous substances and participate in high-risk behaviors. In both injured and uninjured patients who admit using alcohol and marijuana, the ED visit is an opportunity to deliver BI to reduce alcohol and marijuana use and associated risk behaviors and the subsequent injury and

    2012-03-01

    The aim of this study was to analyse the effects of clinical breakpoint changes in CLSI 2010 and 2011 guidelines and EUCAST 2011 guidelines on antibiotic susceptibility testing (AST) reports. In total, 3713 non-duplicate clinical isolates of Enterobacteriaceae, Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Acinetobacter baumannii were analysed. Inhibition zone diameters were determined for β-lactams, carbapenems, fluoroquinolones, aminoglycosides and trimethoprim/sulfamethoxazole. CLSI 2009-11 and EUCAST 2011 clinical breakpoints were applied. Changes in resistance as defined per the guidelines affected individual species and drug classes differently. The cefepime resistance rate in Escherichia coli and Enterobacter cloacae increased from 2.1% and 1.3% to 8.2% and 6.9%, respectively, applying CLSI 2009-11 versus EUCAST 2011 guidelines. Ertapenem resistance rates in E. cloacae increased from 2.6% with CLSI 2009 to 7.2% for CLSI 2010 and 2011, and to 10.1% when applying EUCAST 2011. Cefepime and meropenem resistance rates in P. aeruginosa increased from 12.2% and 20.6% to 19.8% and 27.7%, respectively, comparing CLSI 2009-11 with EUCAST 2011. Tobramycin and gentamicin resistance rates in A. baumannii increased from 15.9% and 25.4% to 34.9% and 44.4% applying CLSI 2009-11 versus EUCAST 2011. Higher resistance rates reported due to breakpoint changes in CLSI and EUCAST guidelines will result in increasing numbers of Gram-negative bacilli reported as multidrug resistant. AST reports classifying amoxicillin/clavulanic acid, cefepime or carbapenem resistance will lead clinicians to use alternative agents. Upon implementation of the EUCAST guidelines, laboratories should be aware of the implications of modified drug susceptibility testing reports on antibiotic prescription policies.

    2011-06-01

    Full Text Available Abstract Background This retrospective study evaluated the impact of disease progression and of specific sites of metastasis on patient reported outcomes (PROs that assess symptom burden and health related quality of life (HRQoL in women with metastatic breast cancer (mBC. Methods HER-2 negative mBC patients (n = 102 were enrolled from 7 U.S. community oncology practices. Demographic, disease and treatment characteristics were abstracted from electronic medical records and linked to archived Patient Care Monitor (PCM assessments. The PCM is a self-report measure of symptom burden and HRQoL administered as part of routine care in participating practices. Linear mixed models were used to examine change in PCM scores over time. Results Mean age was 57 years, with 72% of patients Caucasian, and 25% African American. Median time from mBC diagnosis to first disease progression was 8.8 months. Metastasis to bone (60%, lung (28% and liver (26% predominated at initial metastatic diagnosis. Results showed that PCM items assessing fatigue, physical pain and trouble sleeping were sensitive to either general effects of disease progression or to effects associated with specific sites of metastasis. Progression of disease was also associated with modest but significant worsening of General Physical Symptoms, Treatment Side Effects, Acute Distress and Impaired Performance index scores. In addition, there were marked detrimental effects of liver metastasis on Treatment Side Effects, and of brain metastasis on Acute Distress. Conclusions Disease progression has a detrimental impact on cancer-related symptoms. Delaying disease progression may have a positive impact on patients' HRQoL.

  15. Multimodality palliative treatment of (111)In-pentetreotide negative/(123)I-MIBG positive metastatic carcinoid - a case report.

    Dworakowska, Dorota; Gueorguiev, Maria; Laji, Ken; Grossman, Ashley B

    2008-01-01

    Patients with carcinoid tumours frequently present with metastatic disease. There are only a few therapeutic options for these patients, and the main goal of palliative treatment is to reduce symptoms and thus to improve quality of life. Current therapy includes surgical resection, hepatic artery embolisation, chemotherapy and somatostatin analogue treatment; however, all these options have limitations. It seems probable that therapeutic modalities based on radiopharmaceuticals may provide better therapy, not only in relation to symptom reduction but may also improve patient survival. In this case report we present a 46-year-old woman with a symptomatic carcinoid, who at the time of diagnosis had liver and abdominal lymph node metastases, the primary tumour being located in the terminal ileum. (111)In-pentetreotide scanning was negative, whereas (123)I-MIBG scanning showed high avidity in the tumour tissue. After right hemicolectomy, two courses of (131)I-MIBG treatment were given (12.95 GBq and 12 GBq, respectively). After the second dose of (131)I-MIBG temporary pancytopenia was present. Octreotide therapy was given empirically only for a short time and was stopped because of drug intolerance. The patient underwent tricuspid and pulmonary valve replacement because of her carcinoid heart disease, followed by two courses of embolisation of liver metastases. While (131)I-MIBG therapy reduced the patient's symptoms of flushing and diarrhoea, there has not yet been any effect on tumour response or 5-HIAA production. This case illustrates the multimodality and multidisciplinary approach to such patients.

    Kvale, T.J.

    1992-04-01

    This Technical Progress Report describes the progress made on the research objectives during the past twelve months. This research project is designed to provide measurements of various scattering processes which occur in H{sup {minus}} collisions with atomic (specifically, noble gas and atomic hydrogen) targets at intermediate energies. These processes include: elastic scattering,single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H{sup {minus}} is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements in progress will provide either experimentally-determined cross sections or set upper limits to those cross sections. In either case, these measurements will be stringent tests of our understanding in energetic negative ion-atom collisions. This series of experiments required the construction of a new facility and the initial ion beam was accelerated through the apparatus in April 1991.

    Orthogonal range reporting is the problem of storing a set of n points in d-dimensional space, such that the k points in an axis-orthogonal query box can be reported efficiently. While the 2-d version of the problem was completely characterized in the pointer machine model more than two decades ago...... data structure for the d-dimensional orthogonal range reporting problem in the pointer machine model of computation that uses S(n) space must spend Ω((log n/ log(S(n)/n))⌊d/2⌋--1) time to answer queries. Thus, if S(n)/n is poly-logarithmic, then the query time is at least Ω((log n/ log log n)⌊d/2......) to Ω((log n/ log log n)2 + k) somewhere between three and six dimensions. Finally, we show that our techniques also lead to improved structures for point location in rectilinear subdivisions, that is, the problem of storing a set of n disjoint d-dimensional axis-orthogonal rectangles...

    Previous research suggests that high levels of negative emotions may affect health. However, it is likely that the absence of an emotional response following stressful events may also be problematic. Accordingly, we investigated whether a non-linear association exists between negative emotional...... cardiovascular, metabolic and immune function biomarkers at three clinical follow-up examinations. A non-linear association between negative emotional response and allostatic load was observed: being at either extreme end of the distribution of negative emotional response increased the risk of physiological...

    Background: Triple-negative breast cancers (TNBC) have a more aggressive course and are associated with poorer prognosis in comparison with other subtypes of breast cancer. One of the most common subtypes of TNBC is basal-like. The aim of this study was to investigate clinicopathological characteristics and clinical course of TNBC in Iranian women and compare them with other studies. Subjects and Methods: Between March 2009 and February 2011, patients with breast cancer in Cancer Institute of Iran were selected and then followed-up for 2 years. Paraffin-embedded tumor block of all TNBC patients were evaluated for CK5/6 and EGFR using IHC method. Results: Among 267 breast cancer patients, 60 cases with TNBC were identified (22.5%), 31 patients (51.7%) had basal-like and 29 patients (48.3%) had non-basal-like tumors. The median age of participants with TNBC was 49.6 years. Among our patients, 70% had positive lymph nodes.93.4% of all patients at the time of diagnosis were stage II or III and tumor size was at least 3 centimeters. No grade 1 TNBC was found in this study. During the follow-up period, there were 26 recurrences and 7 deaths. Conclusion: The percentage of basal-like subtype among Iranian women with TNBC was lower compared to other studies, while bone metastases, clinical stage, lymph node involvement and tumor size were higher. Clinicopathological findings in basal and non-basal-like subgroups were not different, but the probability of lymph node involvement was more common in patients who were EGFR positive. PMID:28286613

    Scherrer, Martin C; Dobson, Keith S; Quigley, Leanne

    2014-09-01

    This study identified and examined a set of potential predictors of self-reported negative mood following a depressive mood induction procedure (MIP) in a sample of previously depressed, clinically anxious, and control participants. The examined predictor variables were selected on the basis of previous research and theories of depression, and included symptoms of depression and anxiety, negative and positive affect, negative and positive automatic thoughts, dysfunctional beliefs, rumination, self-concept, and occurrence and perceived unpleasantness of recent negative events. The sample consisted of 33 previously depressed, 22 currently anxious, and 26 non-clinical control participants, recruited from community sources. Participant group status was confirmed through structured diagnostic interviews. Participants completed the Velten negative self-statement MIP as well as self-report questionnaires of affective, cognitive, and psychosocial variables selected as potential predictors of mood change. Symptoms of anxiety were associated with increased self-reported negative mood shift following the MIP in previously depressed participants, but not clinically anxious or control participants. Increased occurrence of recent negative events was a marginally significant predictor of negative mood shift for the previously depressed participants only. None of the other examined variables was significant predictors of MIP response for any of the participant groups. These results identify factors that may increase susceptibility to negative mood states in previously depressed individuals, with implications for theory and prevention of relapse to depression. The findings also identify a number of affective, cognitive, and psychosocial variables that do not appear to influence mood change following a depressive MIP in previously depressed, currently anxious, and control individuals. Limitations of the study and directions for future research are discussed. Current anxiety

    2014-10-01

    We report three cases of external ventricular derivation infections caused by multidrug-resistant Gram-negative rods and treated successfully with intraventricular colistin. The intrathecal or intraventricular use of colistin have been reported in more than 100 cases without any consensus on dosage, duration and type (monotherapy or combination therapy) of treatment. Based on our comprehensive review of the relevant literature relating to both clinical and pharmacokinetic data, we conclude that the intrathecal/intraventricular administration of colistin is a safe and effective option to treat central nervous system infections caused by multidrug-resistant Gram-negative bacteria.

    2007-04-01

    Individuals with higher functioning autism (HFA) fail to translate their cognitive potential into real-life adaptation, and the severity of their symptoms is considerable despite their intellectual ability. This paper reports on a subsample from a larger study (A. Klin et al., in press) analyzed here by autism spectrum subtypes. It focuses on the nature of ability and disability in HFA and Asperger syndrome (AS) in relation to age and IQ. Participants included 32 individuals with autism and 35 with AS. Individuals with AS had significantly higher Verbal IQ scores and less symptomatology than individuals with autism, but their Vineland scores were equally impaired, highlighting the adaptive deficits in ASD regardless of classification. No relationship was found between adaptive functioning and symptom severity.

The Motivation and Pleasure Scale-Self-Report (MPSR is a self-report measure that assesses the motivation and pleasure domains of negative symptoms based on the CAINS. This study evaluated the reliability and validity of a Korean version of the MPSR.Methods: A total of 139 patients with schizophrenia completed the MPSR, CAINS, Scale for the Assessment of Negative Symptoms (SANS, Brief Psychiatric Rating Scales, Calgary Depression Scale for Schizophrenia, and other measures of trait and cognitive function.Results: The 15-item MPSR showed good internal consistency. In addition, it also had a good convergent validity with the Motivation and Pleasure subscale of the CAINS and the anhedonia/avolition subscale of the SANS. The scale was not associated with psychotic symptoms, agitation/mania, and depression/anxiety, and it showed good discriminant validity. MPSR scores were significantly correlated with Behavioral Activation System total score for trait measure.Conclusion: The Korean version of the MPSR is a notable self-report method for examining the severity of negative symptoms in schizophrenia.

    2017-01-01

    Meta-analyses based on peer-reviewed publications report a sensitivity of approximately 85% for rapid antigen streptococcus tests to diagnose group A streptococcal (GAS) pharyngitis. Because these meta-analyses excluded package inserts, we examined the test characteristics of rapid antigen streptococcal tests and molecular methods that manufacturers report in their package inserts. We included tests available in the US market (Food and Drug Administration, period searched 1993-2015) and used package insert data to calculate pooled sensitivity and specificity. To examine quality, we used the Quality Assessment of Diagnostic Accuracy Studies-2. We excluded 26 tests having different trade names but identical methods and data. The study design was prospective in 41.7% (10 of 24). The pooled sensitivity of the most commonly used method, lateral flow/immunochromatographic, was 95% (95% confidence interval [CI] 94-96) and the pooled specificity was 98% (96-98); 7108 patients. The pooled sensitivity of the polymerase chain reaction or molecular methods was 98% (95% CI 96-98) and the pooled specificity was 96% (95% CI 95-97); 5685 patients. Package inserts include sponsored studies that overestimate the sensitivity of rapid tests to diagnose GAS pharyngitis by approximately 10%. Physicians should understand that package inserts overestimate diagnostic test utility; a negative test cannot be used to exclude GAS pharyngitis.

    A 76-year-old woman was referred to our hospital because of anemia. The laboratory findings revealed hemolysis. Although a direct Coombs test was negative, a high titer of RBC-bound IgG was detected, and a diagnosis of Coombs-negative autoimmune hemolytic anemia was made. She was successfully treated with prednisolone. One year and five months later, she again presented anemia and was diagnosed with pure red cell aplasia. Anti-erythropoietin receptor antibody was detected in the serum. She was treated with cyclosporine and obtained prompt recovery. We herein report this rare case and review the pertinent literature.

    2010-06-15

    This final report for the Swiss Federal Office of Energy (SFOE) takes a look at how a modified refrigerator can be given a higher efficiency by modifying the compressor. The modified refrigerator was fitted with a variable-speed compressor. This compressor could be run at much lower speeds so that it was in operation for up to 90% of the time. It was shown that less electricity was consumed the more the compressor ran. The report discusses the aims of the work and presents details on the standard refrigerator used for the tests. The compressor normally used and the variable-speed compressor used in the test are described. Systems for temperature control and data acquisition during the tests are described. The results obtained are examined and the influence of various factors is discussed.

    Negative-pressure wound therapy is a newly developed, noninvasive technique to manage a wide variety of wounds. This novel therapy was successfully used to heal the wound after open-window thoracostomy without surgical closure. A 46-year-old woman was admitted to hospital because of a painful mass on the right side of her chest. Radiological findings revealed an abscess on the right chest wall that had ruptured into the right lung and caused empyema. Antibiotic therapy did not yield sufficient improvement. Open-window thoracostomy was performed to achieve a sterile pleural space, and negative-pressure wound therapy was then applied. The pleural space was reduced, and the patient was discharged home with self-administered wound care. The wound healed completely in 5 months without any need for surgical closure.

    Androgen receptors (ARs) are expressed in more than 70% of breast cancers (BCs) and have been implicated in BC pathogenesis. Some triple negative (TN)BC tumors express AR and may benefit from ARtargeted therapies. The aim of this study was to evaluate survival and the prevalence of AR expression and its correlation with other risk factors in triple negative BCs in women from Western Iran. In a retrospective study between 20092015, 41 patients with TNBC were referred to the Private Clinic of Oncology, Kermanshah city, Iran. ER, PR and ARpositive expression was defined as ≥10% nuclear staining and also HER2 (2+), FISH was performed. Nuclear staining was considered representative for Ki67 and P53. The mean followup for the patients was 25 months. In this time, 5 patients died and 4 lost to followup were censored from survival analysis. The mean age at diagnosis was 46.9 years (range, 2471 years) and all patients were female. The OS rates for ARpositive and ARnegative patients were 90% and 85.1%, respectively, and the mean OS was 26.3 and 23.2 months. Therefore, there was no significant difference between the two groups (Hazard ratio: 0.580, 95% CI: 0.0863.893, P=0.575). In TNBC patients, evaluation of AR status may provide additional information on prognosis and treatment. The results of studies showed that the prevalence AR expression may differ in the world and probably ethnicity can be an influencing factor.

    "In a recent study of male and female ultra-marathoners in a 161-km ultra-marathon, the prevalence of exercise-associated hyponatremia (EAH) was higher than reported for marathoners. Regarding triathletes, the prevalence of EAH has been investigated in Ironman triathletes, but not in Triple Iron ultra-triathletes. The aim of this study was to investigate the prevalence of EAH in male ultra-triathletes competing in a Triple Iron ultra-triathlon over 11.4 km swimming, 540 km cycling, and 126.6 km running. Changes in body mass, fat mass, skeletal muscle mass, total body water, haematocrit, plasma volume, plasma sodium concentration ([Na ⁺ ]) and urine specific gravity were determined in 31 male athletes with (means ± standard deviation) 42.1 ± 8.1 years of age, 77.0 ± 7.0 kg body mass, 1.78 ± 0.06 m body height and a BMI of 24.3 ± 1.7 kg/m² in the 'Triple Iron Triathlon Germany'. Of the 31 finishers, eight athletes (26%) developed asymptomatic EAH. Body mass, fat mass, skeletal muscle mass, and haematocrit decreased, plasma volume increased ( P Iron ultra-triathletes compared to existing reports on Ironman triathletes. Body fluid homeostasis remained stable in these ultra-triathletes although body mass decreased."

    Aim: Hamstring strain injury is common in soccer. The aim of this study was to evaluate the physical capacity of players who have and have not suffered from hamstring strain injury in a sample of semi-professional and professional Norwegian soccer players in order to evaluate characteristics and to identify possible indications of insufficient rehabilitation. Method: Seventy-five semi-professional and professional soccer players (19 ± 3 years) playing at the second and third level in the Norwegian league participated in the study. All players answered a questionnaire, including one question about hamstring strain injury (yes/no) during the previous 2 years. They also performed a 40 m maximal sprint test, a repeated sprint test (8 × 20 m), a countermovement jump, a maximal oxygen consumption (VO2max) test, strength tests and flexibility tests. Independent sample t-tests were used to evaluate differences in the physical capacity of the players who had suffered from hamstring strain injury and those who had not. Mixed between-within subject's analyses of variance was used to compare changes in speed during the repeated sprint test between groups. Results: Players who reported hamstring strain injury during the previous two years (16%) had a significantly higher drop in speed (0.07 vs. 0.02 s, p = 0.007) during the repeated sprint test, compared to players reporting no previous hamstring strain injury. In addition, there was a significant interaction (groups × time) (F = 3.22, p = 0.002), showing that speed in the two groups changed differently during the repeated sprint test. There were no significant differences in relations to age, weight, height, body fat, linear speed, countermovement jump height, leg strength, VO2max, or hamstring flexibility between the groups. Conclusion: Soccer players who reported hamstring strain injury during the previous 2 years showed significant higher drop in speed during the repeated sprint test compared to players with no hamstring

  14. Does High-Quality Financial Reporting Mitigate the Negative Impact of Global Financial Crises on Firm Performance? Evidence from the United Kingdom

    Directory of Open Access Journals (Sweden)

    Zhiwei Lin

    2014-12-01

    Full Text Available Prior literature has claimed that accounting plays a negative role in a financial crisis. The current study sought to determine whether this effect is dependent on the quality of financial reporting. Specifically, this study examined the impact of the quality of financial reporting (as measured via earnings quality on liquidity (measured by the bid-ask spread in the equity market during the 2008–2009 global financial crisis in the United Kingdom. We found, as expected, that market liquidity was much lower during the crisis than prior to the crisis; however, firms with high-quality financial reporting suffered fewer negative effects as a result of the financial crisis. The results were robust after controlling for other influences, such as return volatility, loss making, market value of equity, and other potential endogeneity problems. In addition, adopting alternative models for earnings quality did not alter our inferences. Our results support the notion that high-quality accounting information can reduce information asymmetry and hence enhance investor confidence during a financial crisis. The results suggest that a stable financial reporting system is an important part of that overall economic fabric. Our findings will help build a framework on which an overall financial crisis risk-management strategy can be developed to avoid future crises.

  15. Duodenal Villous Atrophy in a TTG-Negative Patient Taking Olmesartan: A Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Tasha Kulai

    2016-01-01

    Full Text Available Olmesartan, an angiotensin II receptor antagonist used to treat hypertension, is associated with few adverse effects. Here, a case of severe sprue-like enteropathy and acute kidney injury is described in a 68-year-old male taking olmesartan for 3-4 years. He presented to hospital with a five-week history of diarrhea, vomiting, and a 20 lb weight loss. Anti-TTG was negative with a normal IgA. Biopsies of the distal duodenum and duodenal cap revealed marked blunting of the villi with near complete villous atrophy of the biopsies from the bulb. There was an increase in intraepithelial lymphocytes as well as neutrophils in the surface epithelium. The patient’s diarrhea improved upon discontinuation of olmesartan and he returned to his previous weight. Repeat endoscopy four months later demonstrated complete resolution of inflammatory change with normal villous architecture. Long-term olmesartan use is associated with severe sprue-like enteropathy. The mechanism of intestinal injury is unknown. Duodenal biopsy results may mimic other enteropathies such as celiac disease. Physicians should consider medications as potential etiologies of enteropathy.

    Autoimmune pancreatitis (AIP) is a rare disorder frequently manifesting as a mass-like lesion that may lead to obstructive jaundice. We report here a case of pancreatic obstruction with painless jaundice, and elevation of CA 19-9 without elevation of serum IgG4. Contrast enhanced ultrasonography (CE US) revealed the possibility of AIP, and the final pathological findings confirmed the diagnosis. PMID:22586534

    Compensatory health beliefs (the beliefs that an unhealthy behaviour can be compensated by a healthy behaviour) can interfere with adherence to fruit and vegetable consumption recommendations. Fruit and vegetable consumption, social cognitive variables and compensatory health beliefs were investigated via self-report at baseline (T0) and 8-week follow-up (T1) in N = 790 participants. Self-efficacy predicted fruit and vegetable consumption intentions. Planning mediated between intentions and T1 fruit and vegetable consumption. Compensatory health beliefs negatively predicted intentions at low self-efficacy levels only. The results propose the use of self-efficacy interventions to diminish the negative effects of compensatory health beliefs when forming fruit and vegetable consumption intentions and foster planning to translate intentions into behaviour.

    Jonathan E Matthews

    Full Text Available BACKGROUND: A substantial proportion of men who have sex with men (MSM in the United States remain unvaccinated against hepatitis B. We sought to understand which factors are associated with vaccination among HIV-negative MSM. METHODOLOGY/PRINCIPAL FINDINGS: Data were from a 2010 web-based survey of adult MSM. We calculated the prevalence of self-reported hepatitis B vaccination among 1,052 HIV-negative or HIV-untested men who knew their hepatitis B vaccination status, and used multivariate logistic regression to determine associated factors. 679 (64.5% MSM reported being vaccinated. Younger men were more likely to report being vaccinated than older men, and there was a significant interaction between age and history of hepatitis B testing. Men with at least some college education were at least 2.1 times as likely to be vaccinated as men with a high school education or less (95% CI = 1.4-3.1. Provider recommendation for vaccination (aOR = 4.2, 95% CI = 2.4-7.4 was also significantly associated with receipt of vaccination. CONCLUSIONS/SIGNIFICANCE: Providers should assess sexual histories of male patients and offer those patients with male sex partners testing for hepatitis infection and vaccinate susceptible patients. There may be particular opportunities for screening and vaccination among older and more socioeconomically disadvantaged MSM.

    New technical information may lead to scientific beliefs that diverge over time from the a posteriori right answer. We call this phenomenon, which is particularly problematic in the global change arena, negative learning. Negative learning may have affected policy in important cases, including stratospheric ozone depletion, dynamics of the West Antarctic ice sheet, and population and energy projections. We simulate negative learning in the context of climate change with a formal model that embeds the concept within the Bayesian framework, illustrating that it may lead to errant decisions and large welfare losses to society. Based on these cases, we suggest approaches to scientific assessment and decision making that could mitigate the problem. Application of the tools of science history to the study of learning in global change, including critical examination of the assessment process to understand how judgments are made, could provide important insights on how to improve the flow of information to policy makers.

  1. Measurements of scattering processes in negative ion: Atom collisions. Technical progress report, 1 September 1991--31 December 1994

    Energy Technology Data Exchange (ETDEWEB)

    Kvale, T.J.

    1994-09-27

    This report describes the progress made on the research objectives during the past three years of the grant. This research project is designed to study various scattering processes which occur in H{sup {minus}} collisions with atomic (specifically, noble gas and atomic hydrogen) targets in the intermediate energy region. These processes include: elastic scattering, single- and double-electron detachment, and target excitation/ionization. For the elastic and target inelastic processes where H{sup {minus}} is scattered intact, the experimental technique of Ion Energy-Loss Spectroscopy (IELS) will be employed to identify the final target state(s). In most of the above processes, cross sections are unknown both experimentally and theoretically. The measurements will provide total cross sections (TCS) initially, and once the angular positioning apparatus is installed, will provide angular differential cross sections (ADCS).

    This study examined individual differences in exposure to daily stressors and self-reported changes in memory among older adults. A sample of 87 older adults completed measures of daily stressful experiences, negative affect (NA), cognitive interference (CI), and rated their memory compared to six months ago. Results indicated that more frequent exposure to daily stressors was associated with rating one's memory to be worse compared to six months prior. Furthermore, CI, but not NA partially mediated this association. The findings highlight CI as a psychological pathway for understanding the links between daily stress and perceptions of memory and cognition in old age.

    2015-01-01

    Background Under current European Union legislation, two severe hypoglycemic events within 12 months is grounds for driving license withdrawal. The aim of the study reported here was to determine whether fear of such a withdrawal could lead to patients concealing severe hypoglycemia from physicians, which could negatively impact further treatment decisions. Methods A total of 663 patients with insulin-treated diabetes were anonymously surveyed about whether they would conceal severe hypoglycemic events from their physicians, if revealing them could result in driving license withdrawal. This investigation utilized an adapted and expanded questionnaire by Graveling et al. Results Of all diabetic patients surveyed, 26.17% would most likely not report hypoglycemia, and 25.86% were undecided. In a group of patients with type 1 diabetes, 31.83% would likely not report hypoglycemic events, and 25.06% were undecided. The patients least likely to report severe hypoglycemic events were those who indicated that vehicles were partly essential for work, and who also had more than two hypoglycemic events monthly. Conclusion A considerable percentage of diabetic patients would likely conceal severe hypoglycemic events from their physicians due to fear of driving license withdrawal. Patient failure to report severe hypoglycemic events can potentially lead to physicians being misinformed regarding the patient’s condition, which could lead to inadequate monitoring and treatment.

  7. Holographic Quantum Entanglement Negativity

    Chaturvedi, Pankaj; Sengupta, Gautam

    2016-01-01

    We propose a holographic prescription to compute the entanglement negativity for conformal field theories at finite temperatures which exactly reproduces the entanglement negativity for (1+1)- dimensional conformal field theories at finite temperatures dual to (2+1)- dimensional bulk Euclidean BTZ black holes. We observe that the holographic entanglement negativity captures the distillable pure quantum entanglement and is related to the holographic mutual information. The application of our prescription to higher dimensional conformal field theories at finite temperatures within a $AdS_{d+1}/CFT_{d}$ scenario involving dual bulk $AdS$-Schwarzschild black holes is discussed to elucidate the universality of our conjecture.

    Full Text Available El edema agudo pulmonar por presión negativa es una complicación descrita desde 1977 tras la obstrucción de la vía aérea respiratoria, tanto en niños como en adultos. Aunque su etiopatogenia es multifactorial, destaca especialmente la excesiva presión intratorácica negativa causada por la inspiración forzada espontánea de un paciente con la glotis cerrada, que resulta en trasudación de líquido de los capilares pulmonares hacia el espacio alveolointersticial. El edema pulmonar resultante puede aparecer en pocos minutos tras la obstrucción de la vía aérea o de forma diferida al cabo de varias horas. Este cuadro clínico es potencialmente grave, pero habitualmente responde bien al tratamiento con oxigenoterapia, ventilación mecánica a presión positiva y diuréticos. Es importante el diagnóstico de sospecha para adecuar el tratamiento con presteza. Presentamos nuestra experiencia en 3 casos clínicos con edema agudo pulmonar por presión negativa.Negative pressure pulmonary edema is a complication, described since 1977, caused by upper airway obstruction in both children and adults. Although its aetiopathogeny is multifactorial, especially outstanding is excessive negative intrathoracic pressure caused by the forced spontaneous inspiration of a patient against a closed glottis, that causes high arteriole and capillary fluid pressures that favor transudation into the alveolar space The resulting pulmonary edema can appear a few minutes after the obstruction of the airway or in a deferred way after several hours. The clinical manifestations are potentially serious, but normally respond well to treatment with supplemental oxygen, positive pressure mechanical ventilation and diuretics. Diagnostic suspicion is important for acting promptly. We report three clinical cases with acute negative pressure pulmonary edema.

    Multiple comorbidities and environmental factors increase the complications of incisional wounds in patients. It was demonstrated in previous prospective and randomized studies that negative pressure wound therapy (NPWT) reduced wound infection and other complications in clean, closed surgical incisions. In this case report, the Prevena incision management system was implemented on the clean, closed surgical incision of a 52-year-old female patient, who was given a renal transplantation from cadaver postoperatively in the operating theater. It was removed from the patient on the fifth day after the operation. Following the removal of Prevena, the wound and surrounding skin of the patient were observed. Wound healing was complete, and no skin lesion or tool-related complication was found around the wound due to NPWT. The Prevena NPWT system can be conveniently and safely implemented on the operational incision in renal transplant recipients in order to prevent surgical wound complications.

  17. Isotropic Single Negative Metamaterials

    Directory of Open Access Journals (Sweden)

    P. Protiva

    2008-09-01

    Full Text Available This paper presents the application of simple, and therefore cheap, planar resonators for building 3D isotropic metamaterials. These resonators are: a broadside-coupled split ring resonator with a magnetic response providing negative permeability; an electric dipole terminated by a loop inductor together with a double H-shaped resonator with an electric response providing negative permittivity. Two kinds of 3D isotropic single negative metamaterials are reported. The first material consists of unit cells in the form of a cube bearing on its faces six equal planar resonators with tetrahedral symmetry. In the second material, the planar resonators boxed into spherical plastic shells and randomly distributed in a hosting material compose a real 3D volumetric metamaterial with an isotropic response. In both cases the metamaterial shows negative permittivity or permeability, according to the type of resonators that are used. The experiments prove the isotropic behavior of the cells and of the metamaterial specimens.

    This study explored the cross-sectional and predictive effect of drive for thinness and/or negative affect scores on the development of self-reported anorexia nervosa (AN) and bulimia nervosa (BN). K-means were used to cluster the Eating Disorder Inventory-Drive for Thinness (DT) and Child Behavior Checklist Anxious/Depressed (A/D) scores from 615 unrelated female twins at age 16-17. Logistic regressions were used to assess the effect of these clusters on self-reported eating disorder diagnosis at ages 16-17 (n = 565) and 19-20 (n = 451). DT and A/D scores were grouped into four clusters: Mild (scores lower than 90th percentile on both scales), DT (higher scores only on DT), A/D (higher scores only on A/D), and DT-A/D (higher scores on both the DT and A/D scales). DT and DT-A/D clusters at age 16-17 were associated cross-sectionally with AN and both cross-sectionally and longitudinally with BN. The DT-A/D cluster had the highest prevalence of AN at follow-up compared with all other clusters. Similarly, an interaction was observed between DT and A/D that predicted risk for AN. Having elevated DT and A/D scores may increase risk for eating disorder symptomatology above and beyond a high score on either alone. Findings suggest that cluster modeling based on DT and A/D may be useful to inform novel and useful intervention strategies for AN and BN in adolescents. © 2015 Wiley Periodicals, Inc.

    This final rule revises existing regulations under sections 401 through 432 of the Health Care Quality Improvement Act of 1986, governing the National Practitioner Data Bank for Adverse Information on Physicians and Other Health Care Practitioners, to incorporate statutory requirements under section 1921 of the Social Security Act, as amended by section 5(b) of the Medicare and Medicaid Patient and Program Protection Act of 1987 (MMPPPA), and as amended by the Omnibus Budget Reconciliation Act of 1990 (OBRA). The MMPPPA, along with certain additional provisions in the OBRA, was designed to protect program beneficiaries from unfit health care practitioners, and otherwise improve the anti-fraud provisions of Medicare and State health care programs. Section 1921, the statutory authority upon which this regulatory action is based, requires each State to adopt a system of reporting to the Secretary of Health and Human Services (the Secretary) certain adverse licensure actions taken against health care practitioners and health care entities licensed or otherwise authorized by a State (or a political subdivision thereof) to provide health care services. It also requires each State to report any negative actions or findings that a State licensing authority, peer review organization, or private accreditation entity has concluded against a health care practitioner or health care entity.

  5. Assessing Repetitive Negative Thinking Using Categorical and Transdiagnostic Approaches: A Comparison and Validation of Three Polish Language Adaptations of Self-Report Questionnaires.

    Kornacka, Monika; Buczny, Jacek; Layton, Rebekah L

    2016-01-01

    Repetitive negative thinking (RNT) is a transdiagnostic process involved in the risk, maintenance, and relapse of serious conditions including mood disorders, anxiety, eating disorders, and addictions. Processing mode theory provides a theoretical model to assess, research, and treat RNT using a transdiagnostic approach. Clinical researchers also often employ categorical approaches to RNT, including a focus on depressive rumination or worry, for similar purposes. Three widely used self-report questionnaires have been developed to assess these related constructs: the Ruminative Response Scale (RRS), the Perseverative Thinking Questionnaire (PTQ), and the Mini-Cambridge Exeter Repetitive Thought Scale (Mini-CERTS). Yet these scales have not previously been used in conjunction, despite useful theoretical distinctions only available in Mini-CERTS. The present validation of the methods in a Polish speaking population provides psychometric parameters estimates that contribute to current efforts to increase reliable replication of theoretical outcomes. Moreover, the following study aims to present particular characteristics and a comparison of the three methods. Although there has been some exploration of a categorical approach, the comparison of transdiagnostic methods is still lacking. These methods are particularly relevant for developing and evaluating theoretically based interventions like concreteness training, an emerging field of increasing interest, which can be used to address the maladaptive processing mode in RNT that can lead to depression and other disorders. Furthermore, the translation of these measures enables the examination of possible cross-cultural structural differences that may lead to important theoretical progress in the measurement and classification of RNT. The results support the theoretical hypothesis. As expected, the dimensions of brooding, general repetitive negative thinking, as well as abstract analytical thinking, can all be classified

    2013-01-01

    Over the past decade there has been a lack of attention in the discipline paid to developing strong academic leaders. It is widely acknowledged that the role of the dean has shifted dramatically over the past two decades, with an increasing emphasis on interaction with and accountability to external constituencies at the university, community, and national levels. The overall purpose of this study was to investigate the self-reported leadership styles, behaviors, and experiences of deans of schools of nursing in the United States. The Multifactor Leadership Questionnaire (MLQ) was sent to 655 deans who were members of the American Association of Colleges of Nursing; 344 returned completed surveys for a return rate of 52.5%. Scores on the transformational scale (n = 321; 20 items) ranged from 2.75 to 4.0, with a mean of 3.79; transactional scores ranged from 1.3 to 4.0, with a mean of 3.3 and mode of 3.5. The passive leadership component was lowest, with a range of 0 to 3.75, mean of 1.1, and mode of 1.0. The highest scores for each dean were then examined and compared across the three components. Seventy-seven percent of the deans' highest scores fell on the transformational, 21% on the transactional, and 2% on the passive-avoidant scale. There were no significant differences in the most commonly reported leadership behaviors by gender, ethnicity, or terminal degree. Deans of nursing, compared with over 3,000 other leaders who have completed the MLQ, ranked in the 80th percentile for self-reported transformative behaviors and outcomes effectiveness. The findings from this sample, who were predominantly female, are congruent with previous research on women leaders. Recommendations for future research leadership development programs are presented.

    Full Text Available A 76-year-old gentleman presented with anemia. He had a history of perforated duodenal ulcer six years ago, with Billroth II repair performed. A large gastric bezoar (8X6cm2 with a clean base ulcer at the anastomotic junction was found during the initial Oesophago-gastro-duodenoscopy (OGDS. Rapid urease test was negative. He presented with melena during the subsequent follow up (OGDS showed a Forrest Ib prepylori ulcer. We have successful removed the gastric bezoar with dissolution therapy initially (injection of coke-cola into the bezoar, followed by drinking 325ml coca-cola twice daily, followed by four attempts of OGDS with endoscopic fragmentation. Histopathology reported as degenerated vegetable matter, acellular debris mixed with scattered fungal and bacterial colonies, which was compatible with bezoar. Follow up OGDS showed complete clearance of the bezoar. Coca-cola ingestion should be considered as initial treatment as it is non-invasive, and it enables further successful endoscopic fragmentation.

    Directory of Open Access Journals (Sweden)

    Jeffrey Carson

    2012-01-01

    Full Text Available We present a case of a 3-year-old male originally diagnosed with a CD30+ anaplastic cutaneous T-cell lymphoma with no evidence of systemic disease after CT scan, PET scan, and bone marrow aspiration. Sentinel lymph node biopsy (SLNB was performed as an additional step in the workup and showed microscopic disease. Current management/recommendations for cutaneous T-cell lymphoma do not include SLNB. Medical and surgical management of cutaneous malignancies is dramatically different for local versus advanced disease. Therefore adequate evaluation is necessary to properly stage patients for specific treatment. Such distinction in extent of disease suggests more extensive therapy including locoregional radiation and systemic chemotherapy versus local excision only. Two international case reports have described SLNB in cutaneous T-cell lymphoma with one demonstrating evidence of node positive microscopic disease despite a negative metastatic disease workup. This case is being presented as a novel case in a child with implications including lymphoscintigraphy and SLNB as a routine procedure for evaluation and staging of cutaneous T-cell lymphoma if the patient does not demonstrate evidence of metastatic disease on routine workup.

    Blast injuries, caused by explosions accompanied by high-pressure waves, produce tissue damage in the acute period, followed in the later period by circulatory disorders due to vascular endothelial damage and related tissue necrosis. Blunt rectal perforation is rare and difficult to diagnose. In the acute period following blast pelvic injuries, the main objectives are to stop bleeding, minimise contamination and preserve the patient's life. The patient in this report had major vascular injuries, severe pelvic injury and, in the later period, rectal perforation because of vascular endothelial damage caused by the blast effect. Our aim was to treat the patient conservatively because of his poor general condition. We placed a self-expanding covered stent (SECS) into the rectum and then applied negative pressure wound therapy (NPWT; V.A.C.® Therapy, KCI) to the pelvic region and perirectal area. At the end of the treatment, the rectal perforation was closed, and the patient was discharged with healing. In this article, we discuss the novel use of an SECS with NPWT and review related literature.

    Full Text Available Abstract Background Equine infectious anemia virus (EIAV, a lentivirus that infects horses, has been utilized as an animal model for the study of HIV. Furthermore, the disease associated with the equine lentivirus poses a significant challenge to veterinary medicine around the world. As with all lentiviruses, EIAV has been shown to have a high propensity for genomic sequence and antigenic variation, especially in its envelope (Env proteins. Recent studies have demonstrated Env variation to be a major determinant of vaccine efficacy, emphasizing the importance of defining natural variation among field isolates of EIAV. To date, however, published EIAV sequences have been reported only for cell-adapted strains of virus, predominantly derived from a single primary virus isolate, EIAVWyoming (EIAVWY. Results We present here the first characterization of the Env protein of a natural primary isolate from Pennsylvania (EIAVPA since the widely utilized and referenced EIAVWY strain. The data demonstrated that the level of EIAVPA Env amino acid sequence variation, approximately 40% as compared to EIAVWY, is much greater than current perceptions or published reports of natural EIAV variation between field isolates. This variation did not appear to give rise to changes in the predicted secondary structure of the proteins. While the EIAVPA Env was serologically cross reactive with the Env proteins of the cell-adapted reference strain, EIAVPV (derivative of EIAVWY, the two variant Envs were shown to lack any cross neutralization by immune serum from horses infected with the respective virus strains. Conclusion Taking into account the significance of serum neutralization to universal vaccine efficacy, these findings are crucial considerations towards successful EIAV vaccine development and the potential inclusion of field isolate Envs in vaccine candidates.

    Neutral beam injection (NBI) systems provide both heating and current drive in tokamak fusion reactors. High energy (> 1 MeV) neutral beams are produced by neutralising accelerated ions, for which negative ions are used; the neutralisation cross section for positive ions becomes negligible at these energies. This requires very high throughput negative ion sources. Currently this is achieved using inductively coupled plasma sources, which incorporate caesium to improve the production rate. It has been proposed that helicon plasma sources could provide a more efficient, higher throughput method of producing negative ions for NBI, possibly even removing the need for caesium. We report on studies of the negative hydrogen ion population in the MAGPIE helicon device (Australian National University) under a variety of operating conditions. The probe-based laser photodetachment method and Langmuir probes are employed to estimate the negative hydrogen ion density throughout the device. Initial results support the viability of helicon-based negative ion sources.

    The principal purpose of DOE Cooperative Agreement DE-FC28-04RW12232 is to develop and continue providing the public and the U.S. Department of Energy’s (DOE) Office of Civilian Radioactive Waste Management (OCRWM) with an independently derived, unbiased body of scientific and engineering data concerning the study of Yucca Mountain as a potential high-level radioactive waste repository. Under this agreement, the Nevada System of Higher Education (NSHE), formerly the University and Community College System of Nevada (UCCSN), performs scientific or engineering research, and maintains and fosters collaborative working relationships between government and academic researchers. In performing these activities, the NSHE has already developed and implemented a Quality Assurance (QA) program, which was accepted by the DOE Office of Quality Assurance, under the previous Cooperative Agreement Number DE-FC28-98NV12081. The following describes the objectives of Project Activity 002 “Quality Assurance Program” under cooperative agreement DE-FC28-04RW12232. The objective of this QA program was to assure that data produced under the cooperative agreement met the OCRWM QA Requirements and Description (QARD) requirements for quality-affecting (Q) data. The QA Program was written to address specific QARD requirements historically identified and incorporated in Q activities to the degree appropriate for the nature, scope, and complexity of the activity. Additional QARD requirements were integrated into the program when required to complete a specific activity. NSHE QA staff developed a detailed matrix to address each QARD element, identifying the applicable requirements and specifying where each requirement is addressed in the QA program procedures, or identify requirements as “not applicable” to the QA program. Controlled documents were prepared in the form of QA procedures (QAPs) and implementing procedures (IPs). NSHE identified new QAPs and IPs when needed. NSHE PIs

    The Good Behavior Game (GBG) is a universal classroom-based preventive intervention directed at reducing early aggressive, disruptive behavior and improving children's social adaptation into the classroom. The GBG is one of the few universal preventive interventions delivered in early elementary school that has been shown to reduce the risk for future suicide attempts. This paper addresses one potential mechanism by which the GBG lowers the risk of later suicide attempt. In this study, we tested whether the GBG, by facilitating social adaptation into the classroom early on, including the level of social preference by classmates, thereby lowers future risk of suicide attempts. The measure of social adaptation is based on first and second grade peer reports of social preference ("which children do you like best?"; "which children don't you like?"). As part of the hypothesized meditational model, we examined the longitudinal association between childhood peer social preference and the risk of future suicide attempt, which has not previously been examined. Data were from an epidemiologically based randomized prevention trial, which tested the GBG among two consecutive cohorts of first grade children in 19 public schools and 41 classrooms. Results indicated that peer social preference partially mediated the relationship between the GBG and the associated reduction of risk for later suicide attempts by adulthood, specifically among children characterized by their first grade teacher as highly aggressive, disruptive. These results suggest that positive childhood peer relations may partially explain the GBG-associated reduction of risk for suicide attempts and may be an important and malleable protective factor for future suicide attempt.

    Lower family cohesion is associated with adolescent internalizing and externalizing problems. However, there are likely individual differences in youth's responses to family processes. For example, adolescents higher in negative emotional reactivity, who often exhibit elevated physiological responsivity to context, may be differentially affected by family cohesion. We explored whether youth's negative emotional reactivity moderated the relation between family cohesion and youth's symptoms and tested whether findings were consistent with the diathesis-stress model or differential susceptibility hypothesis. Participants were 651 adolescents (M = 12.99 ± .95 years old; 72% male) assessed at two time points (Time 1, ages 12-14; Time 2, age 16) in Pittsburgh, PA. At Time 1, mothers reported on family cohesion and youth reported on their negative emotional reactivity. At Time 2, youth reported on their symptoms. Among youth higher in negative emotional reactivity, lower family cohesion predicted higher symptoms than higher family cohesion, consistent with the diathesis-stress model.

    To examine changes in the association between pain and patient quality of life (QoL), depressive symptoms, and disability in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) at varying levels of spouse responses to pain. One-hundred eighty-eight men with CP/CPPS completed a questionnaire, including demographic information. The outcome variables were mental QoL (SF-12 MCS), physical QoL (SF-12 PCS), depressive symptoms (Center for Epidemiological Studies Depression Scale), and disability (Pain Disability Index). Patients also reported on the types of responses they had from their spouses (Multidimensional Pain Inventory), and pain (Short-Form McGill Pain Questionnaire). The association between pain and disability was stronger at higher levels of solicitous responses (eg, "Does some of my chores") (β = 0.66, P patient pain and associated disability, or may help create or maintain the patient's pain and disability. In either case, distracting rather than solicitous responses to patient pain are to be encouraged in symptom management. Copyright © 2011 Elsevier Inc. All rights reserved.

    Negative hydrogen/deuterium ions can be formed by processes occurring in the plasma volume and on surfaces facing the plasma. The principal mechanisms leading to the formation of these negative ions are dissociative electron attachment to ro-vibrationally excited hydrogen/deuterium molecules when the reaction takes place in the plasma volume, and the direct electron transfer from the low work function metal surface to the hydrogen/deuterium atoms when formation occurs on the surface. The existing theoretical models and reported experimental results on these two mechanisms are summarized. Performance of the negative hydrogen/deuterium ion sources that emerged from studies of these mechanisms is reviewed. Contemporary negative ion sources do not have negative ion production electrodes of original surface type sources but are operated with caesium with their structures nearly identical to volume production type sources. Reasons for enhanced negative ion current due to caesium addition to these sources are discussed.

    Overweight and obesity are metabolic disorders that have become a public health problem due to the current high prevalence; therefore, it is important to create simple monitoring systems to assess their trends. To determine the correlation between weight, height and body mass index reported by patients and the values measured directly in adults between 25 and 50 years old without higher education. A cross-sectional descriptive study was conducted with participation of 207 adults between 25 and 50 years old. Each participant was asked weight and height; and body mass index was calculated with these data. Moreover, a qualified person determined the real value of these variables. The coefficient of intra-class correlation between self-reported and measurements was obtained. The body mass index measured for men was 25.8±3.7 kg/m2 and for women 26.0±4.1 kg/m2. Intraclass correlation coefficients were for weight 0.962 (IC95%: 0.950-0.971), height 0.909 (IC95%: 0.882-0.930), and body mass index 0.929 (IC95% 0.907-0.945); the real prevalence of people with a body mass index greater than 25 kg/m2 was 52.1%, whereas the value obtained by self-reported data was 44%. Self-reported weight and height data are useful for obesity assessment in adults aged between 25 and 50 years without higher education at the population level. Copyright AULA MEDICA EDICIONES 2014.

    This study is the first nationwide population survey to explore the association between speed of eating and degree of obesity. The objective was to cross-sectionally examine the relationship between self-reported speed of eating and body mass index (BMI; calculated as kg/m(2)) in a nationally representative sample of New Zealand women. In May 2009, a sample of 2,500 New Zealand women aged 40 to 50 years was randomly selected from the nationwide electoral rolls. A 66% participation rate was achieved. Potential participants were mailed a self-administered questionnaire containing questions on self-reported speed of eating, demographics, health conditions, menopause status, physical activity, height, and weight. Univariate models were used to examine the associations between demographic, health and behavioral variables, and BMI, while a multivariate model was developed to investigate the relationship between self-reported speed of eating and BMI. After adjusting for age, smoking status, menopause status, thyroid condition, ethnicity, socioeconomic status, and physical activity, BMI statistically significantly increased by 2.8% (95% confidence interval: 1.5% to 4.1%; P<0.001) for each category increase in self-reported speed of eating. Although the direction of causality requires confirmation in longitudinal and randomized intervention studies, the results suggest that faster eating is associated with higher BMI in middle-aged women.

    Full Text Available The striking similarity displayed at the mechanistic level between tumorigenesis and the generation of induced pluripotent stem cells and the fact that genes and pathways relevant for embryonic development are reactivated during tumor progression highlights the link between pluripotency and cancer. Based on these observations we tested whether it is possible to use a pluripotency-associated transcriptional reporter, whose activation is driven by the SRR2 enhancer from the Sox2 gene promoter (named S4+ reporter, to isolate cancer stem cells from breast cancer cell lines. The S4+ pluripotency transcriptional reporter allows the isolation of cells with enhanced tumorigenic potential and its activation was switched on and off in the cell lines studied, reflecting a plastic cellular process. Microarray analysis comparing the populations in which the reporter construct is active vs. inactive showed that positive cells expressed higher mRNA levels of cytokines (IL-8, IL-6, TNF and genes (such as ATF3, SNAI2, KLF6 previously related with the cancer stem cell phenotype in breast cancer.

    The current state of health care demands higher-value care. Due to many barriers, clinicians routinely do not implement evidence-based care even though it is known to improve quality and reduce cost of care. The purpose of this case report is to describe a theory-based, multitactic implementation of a quality improvement process aimed to deliver higher-value physical therapy for patients with low back pain. Patients were treated from January 2010 through December 2014 in 1 of 32 outpatient physical therapy clinics within an academic health care system. Data were examined from 47,755 patients (mean age=50.3 years) entering outpatient physical therapy for management of nonspecific low back pain, with or without radicular pain. Development and implementation tactics were constructed from adult learning and change management theory to enhance adherence to best practice care among 130 physical therapists. A quality improvement team implemented 4 tactics: establish care delivery expectations, facilitate peer-led clinical and operational teams, foster a learning environment focused on meeting a population's needs, and continuously collect and analyze outcomes data. Physical therapy utilization and change in functional disability were measured to assess relative cost and quality of care. Secondarily, charge data assessed change in physical therapists' application of evidence-based care. Implementation of a quality improvement process was measured by year-over-year improved clinical outcomes, decreased utilization, and increased adherence to evidence-based physical therapy, which was associated with higher-value care. When adult learning and change management theory are combined in quality improvement efforts, common barriers to implementing evidence-based care can be overcome, creating an environment supportive of delivering higher-value physical therapy for patients with low back pain. © 2015 American Physical Therapy Association.

    Full Text Available Abstract A 56-year-old man noticed discomfort in his left lower limb, followed by convulsion and numbness in the same area. Magnetic resonance imaging (MRI showed white matter lesions in the right parietal lobe accompanied by leptomeningeal or leptomeningeal and cortical post-contrast enhancement along the parietal sulci. The patient also exhibited higher brain dysfunction corresponding with the lesions on MRI. Histological pathology disclosed β-amyloid in the blood vessels and perivascular inflammation, which highlights the diagnosis of cerebral amyloid angiopathy (CAA-related inflammation. Pulse steroid therapy was so effective that clinical and radiological findings immediately improved. CAA-related inflammation is a rare disease, defined by the deposition of amyloid proteins within the leptomeningeal and cortical arteries associated with vasculitis or perivasculitis. Here we report a patient with CAA-related inflammation who showed higher brain dysfunction that improved with steroid therapy. In cases with atypical radiological lesions like our case, cerebral biopsy with histological confirmation remains necessary for an accurate diagnosis.

    Populations of Painted Bunting (Passerina ciris) have been declining annually over the past 35 years. A cursory survey indicates that illegal trapping of Painted Buntings for a black market cage-bird trade is widespread in southeastern Florida. Coupled with other negative factors confronting the eastern population, the trapping of buntings for the cagebird trade may, in time, produce dire results for this native songbird. Law enforcement personnel need to continue to monitor the illegal activity of trapping native passerines for the local songbird market and to continue to arrest those who support it.

    To understand negative numbers, must we refer to positive number representations (the phylogenetic hypothesis), or do we acquire a negative mental number line (the ontogenetic hypothesis)? In the experiment reported here, participants made lateralized button responses to indicate the larger of two digits from the range -9 to 9. Digit pairs were displayed spatially congruent or incongruent with either a phylogenetic or an ontogenetic mental number line. The pattern of decision latencies suggests that negative numbers become associated with left space, thus supporting the ontogenetic view.

The study presented a case of a 62-year old male patient after several consecutive wound dehiscence episodes who was primarily treated for rectal cancer by means of low anterior resection of the rectum. Due to acute respiratory insufficiency after several operations, wound necrosis with dehiscence was observed. Considering the high risk of perioperative death we abandoned surgical treatment and introduced conservative management using negative pressure wound therapy until the patient's health improved. Literature regarding the above-mentioned issue was also reviewed.

In case all biomass is going to be harvested the nutrient cycle is no longer in balance and deminishing of soil fertility may occur. Questions to be answered are (1) How much biomass can be removed from a system without negative effects on soil fertility?; (2) Discuss the factors that determine these effects on soil fertility, with special emphasis on straw in Poland; (3) Discuss the effect on farm management and agri-economy. The Biomass Upstream Steering committee (BUS), consisting of the participating consortium partners, was created to generate new ideas, select and rank the most promising ones to be worked out in more detail and to invite market parties to jointly set up R and D projects on upstream biomass.

    Light carries angular momentum, and as such it can exert torques on material objects. Applications of these opto-mechanical effects were limited initially due to their smallness in magnitude, but later becomes powerful and versatile after the invention of laser. Novel and practical approaches for harvesting light for particle rotation have since been demonstrated, where the structure is always subjected to a positive optical torque along a certain axis if the incident angular momentum has a positive projection on the same axis. We report here an interesting phenomenon of "negative optical torque", meaning that incoming photons carrying angular momentum rotate an object in the opposite sense. Surprisingly this can be realized quite straightforwardly in simple planar structures. Field retardation is a necessary condition and discrete rotational symmetry of material object plays an important role. The optimal conditions are explored and explained.

    Clamshell incision is a standard approach for bilateral lung transplantation, providing a good operative field; however, once wide dehiscence occurs, its management is sometimes difficult because of intense immunosuppression and malnutrition of the recipient. A 22-year-old man with idiopathic pulmonary arterial hypertension underwent cadaveric bilateral lung transplantation through a clamshell incision using standard cardiopulmonary bypass. He developed wound dehiscence on postoperative day (POD) 20 that resulted in exposure of the bilateral fifth ribs and open pneumothorax. Considering the extreme malnutrition and emaciation of the recipient, we avoided initial closure of the dehiscence. After the debridement of necrotic tissue, negative pressure wound therapy was initiated on POD 25 and was continued for approximately 6 months with trafermin spray application. Eventually, the wound, including the fifth ribs, was completely covered with granulation tissue except for the wire tying the sternum. On POD 217, the patient underwent removal of the sternal wire followed by split-thickness skin grafting. His wound was successfully closed and he was discharged without activity limitation on POD 265.

    Fournier gangrene is a rare but highly infectious disease characterized by fulminant necrotizing fasciitis involving the genital and perineal regions. Negative pressure wound therapy (NPWT; KCI USA Inc, San Antonio, TX) is a widely adopted technique in many clinical settings. Nevertheless, its application and effect in the treatment of Fournier gangrene are unclear. A 47-year-old male patient was admitted with an anal abscess followed by a spread of the infection to the scrotum, which was caused by Pseudomonas aeruginosa. NPWT was applied on the surface of the scrotal area and continued for 10 days. A split-thickness skin graft from the scalp was then grafted to the wound, after which, NPWT utilizing gauze sealed with an occlusive dressing and connected to a wall suction was employed for 7 days to secure the skin graft. At discharge, the percentage of the grafted skin alive on the scrotum was 98%. The wound beside the anus had decreased to 4 × 0.5 cm with a depth of 1 cm. Follow-up at the clinic 1 month later showed that both wounds had healed. The patient did not complain of any pain or bleeding, and was satisfied with the outcome. NPWT before and after split-thickness skin grafts is safe, well tolerated, and efficacious in the treatment of Fournier gangrene.

    Full Text Available The myeloproliferative diseases (MPDs or myelo-proliferative neoplasms (MPNs are a group of diseases of the bone marrow in which excess cells are produced. Chronic idiopathic myelofibrosis (CIMF is a stem cell defect characterized by splenomegaly with multiorgan extramedullary hematopoiesis, immature peripheral blood granulocytes and erythrocytes and progressive bone marrow fibrosis. The most common chromosomal abnormalities seen in CIMF patients include numerical changes of chromosomes 7, 8 and 9, and structural changes of 1q, 5q, 13q and 20q. At least 75.0% of patients with bone marrow abnormalities have one or more of these chromosomal anomalies. Detection of the Janus kinase 2 (JAK2 mutation may be a potential major breakthrough for understanding the pathobiology of MPNs, and is an essential part of the diagnostic algorithm. In this study, we describe a JAK2V617F mutation negative CIMF patient who has the chromosomal translocation t(3;12(q26;q21 in her karyotype.

    Full Text Available Scholars have recently started to integrate personality traits into models of political participation. In this paper, we present the results of a survey experiment (N = 724 designed to test whether negative political messages differentially impact people with different personality traits. We found evidence that individuals with high scores on agreeableness were less likely, and individuals with high scores on extraversion were more likely, to report intending to participate in politics than their counterparts after being exposed to negative political messages. Agreeableness and extraversion also interacted with negative messages to influence specific intentions to make a political donation, attend a meeting, rally, or event, and volunteer for a political campaign. We also found suggestive evidence that agreeableness interacted with negativity to influence turnout intentions. The results of this study have important implications for the study of political engagement, the ways in which people interact with political information, and the practice of democratic politics.

    Biodiversity research increasingly relies on distribution networks for dealing with large-scale primary data.Up-to-date information on biodiversity is critical for the proper management and conservation of any area. The first step towards conservation should be to compile an authoritative species inventory or checklist. Catalogue of Life:Higher Plants in China (CNPC) is an ongoing biodiversity informatics project with the aim to integrate existing higher plants inventory data, and provide access via an internet based web service to public user and the scientific com-munity. The CNPC, for the first time, provides integrated and authoritative taxonomic information on higher plant species found in China, and this database will be permanent, free and continously updated. Presently, a total of 34377 species have been included in the database. Among of them, 16 620 species are only found in China. Taxa are classified into 432 families and 3 941 genera. The CNPC will be an important source for scientists working on Chinese flora, and will play an important role in helping to achieve the targets set under the Global Strategy for Plant Conservation in the future.

    Research consistently shows a positive association between racial discrimination and problematic alcohol use among African Americans, but little is known about the micro-processes linking this pernicious form of stress to drinking. One possibility is that the cumulative effects of discrimination increase individuals' likelihood of negative-mood-related drinking. In the current study, we examined whether individual differences in lifetime perceived racial discrimination among African American college students moderate relations between daily negative moods and evening alcohol consumption in both social and nonsocial contexts. Data came from an online daily diary study of 441 African Americans (58% female) enrolled at a historically black college/university. Lifetime discrimination was measured at baseline. For 30 days, students reported the number of drinks they consumed the night before both socially and nonsocially, as well as their daytime level of negative mood. In support of the hypotheses, only men who reported higher (vs. lower) lifetime discrimination showed a positive association between daily negative mood and that evening's level of nonsocial drinking. Contrary to expectation, women who reported higher (vs. lower) discrimination showed a negative association between daily negative mood and nonsocial drinking. Neither daily negative mood nor lifetime discrimination predicted level of social drinking. These findings provide further evidence that the cumulative impact of racial discrimination may produce a vulnerability to negative-mood-related drinking--but only for African American men. Importantly, these effects emerged only for nonsocial drinking, which may further explain the robust association between discrimination and problematic alcohol use.

    Full Text Available Strongyloides stercoralis is an intestinal nematode that causes strongyloidiasis, which affects 30 to 100 million people worldwide. Risk factors for hyperinfection and disseminated disease include immunosuppressive drug therapy, human T-lymphotropic virus-1 (HTLV-1 infection, solid organ and bone marrow transplantation, hematologic malignant diseases, hypogammaglobulinemia, and severe malnutrition and associated conditions. The diagnosis can be difficult because a single stool examination fails to detect larvae in up to 70% of the cases, and the symptoms are nonspecific. Although eosinophilia is a common finding in patients with chronic Strongyloides infection, it is an unreliable predictor of hyperinfection. Furthermore, the lack of eosinophilia while receiving immunosuppressive therapy cannot reliably exclude the underlying chronic Strongyloides infection. We report here a fatal Strongyloides hyperinfection in a patient receiving allogeneic stem cell transplantation; risk factors and outcome in this clinical setting are discussed.

  17. Final Technical Report HFC Concrete: A Low­Energy, Carbon-Dioxide­Negative Solution for reducing Industrial Greenhouse Gas Emissions

    2012-05-14

    Solidia/CCSM received funding for further research and development of its Low Temperature Solidification Process (LTS), which is used to create hydrate-free concrete (HFC). LTS/HFC is a technology/materials platform that offers wide applicability in the built infrastructure. Most importantly, it provides a means of making concrete without Portland cement. Cement and concrete production is a major consumer of energy and source of industrial greenhouse gas (GHG) emissions. The primary goal of this project was to develop and commercialize a novel material, HFC, which by replacing traditional concrete and cement, reduces both energy use and GHG emissions in the built infrastructure. Traditional concrete uses Portland Cement (PC) as a binder. PC production involves calcination of limestone at {approx}1450 C, which releases significant amounts of CO{sub 2} gas to the atmosphere and consumes a large amount of energy due to the high temperature required. In contrast, HFC is a carbonate-based hydrate-free concrete (HFC) that consumes CO{sub 2} gas in its production. HFC is made by reaction of silicate minerals with CO{sub 2} at temperatures below 100 C, more than an order-of-magnitude below the temperature required to make PC. Because of this significant difference in temperature, it is estimated that we will be able to reduce energy use in the cement and concrete industry by up to 30 trillion Btu by 2020. Because of the insulating properties of HFC, we believe we will also be able to significantly reduce energy use in the Building sector, though the extent of this saving is not yet quantified. It is estimated that production of a tonne of PC-based concrete requires about 6.2 million Btu of energy and produces over 1 tonne of CO{sub 2} emissions (Choate, 2003). These can be reduced to 1.9 million Btu and 0.025 tonnes of CO{sub 2} emissions per tonne of HFC (with overall CO{sub 2}-negativity possible by increasing carbonation yield). In this way, by replacing PC

    The present study examined the associations between authoritarian parenting beliefs, attributions of hostile intent, negative affect, and harsh parenting practices. General population parents (N=183; 31.1% fathers) completed self-report measures of authoritarian parenting beliefs and read vignettes describing children engaging in transgressions. Following each vignette, parents indicated the extent to which they would attribute hostile intent to the child, feel negative affect, and respond with harsh parenting practices (e.g., yelling, hitting). As hypothesized, parents who subscribed to higher levels of authoritarian beliefs attributed more hostile intent to the child and expected to feel more negative affect in response to the transgressions. In turn, higher levels of hostile attributions and negative affect were associated with increased likelihood of harsh parenting practices. Results from a path analysis revealed that the association between authoritarian parenting beliefs and harsh parenting practices was fully explained by attributions of hostile intent and negative affect.

    Full Text Available Introduction One of the problems that people with schizophrenia face is the inability to understand and interpret the sensory input from the environment. This report aims to describe the effects of the sensory integration approach on non-paranoid schizophrenia. The treatment involved eight sessions held 3 days a week and lasting 45 minutes each. The patient had a defined Iranians form social relationships schizophrenia evaluated and treatment. Sensory integration therapy in these patients focused on the following elements: vestibular and proprioceptive senses, exercises to improve walking, improving upper extremity coordination and movement, writing activities, cognitive skills, activities of daily living, and family therapy. Case Presentation The subject (A.H. was a 32-year-old male graduate student with no history of previous hospitalization. His diagnosis was schizophrenia. The reason for his hospitalization was that he was angry and violent toward his family. In addition, the patient had limited verbal and nonverbal skills, issues with self-control, and restricted community involvement. The results of the patient’s treatment for schizophrenia was assessed via a questionnaire on social skills. Conclusions After eight sessions, increased awareness of the environment, improved posture and gait pattern, improved motivation and enjoyment, improved patient tolerance, improved appearance and personal hygiene, loss of purposeful behavior, a realistic plan of action every day, improved attention span, improved decision-making skills, and improved community involvement and coping skills were achieved. The environment is rich in sensory stimuli. The integration and processing of each individual senses creates different behavioral responses. The results showed that a sensory integration approach combined with drug therapy is an effective treatment for patients with schizophrenia.

    The cytological examination of peri-prosthetic breast effusions allowed the diagnosis of bilateral breast-implant ALK-negative anaplastic large cell lymphoma (BI-ALCL) in the case reported. Ten years after reconstructive surgery with bilateral breast implants, a large unilateral seroma developed and was cytologically analyzed. The presence of CD30 and CD4-positive large-sized atypical lymphoid cells exhibiting horseshoe-shaped nuclei and a brisk mitotic activity rendered the diagnosis of BI-ALCL. Similar cells were seen in the peri-prosthetic fluid intraoperatively collected from the contralateral breast. Although initial histological analysis of the capsulectomy specimens showed unilateral tumor, the cytological findings prompted a more thorough tissue sampling, resulting in the diagnosis of bilateral disease. BI-ALCL usually follows an indolent clinical course; however, there are reported cases with an aggressive behavior. While the presence of bilateral disease is a putative risk factor for a bad prognosis, the small number of cases reported precludes a definitive assessment of this risk. Since most BI-ALCL present with late seromas, cytologic analysis of these effusions in women with breast implants should be mandatory. Cytology is a safe tool for diagnosis and follow-up of patients with breast implant-related late seromas, sometimes proven more sensitive than histological analysis. Complete bilateral capsulectomy and a detailed histological analysis should follow a cytological diagnosis of BI-ALCL in a breast effusion in order to avoid false negative diagnoses. Our case constitutes the first published report of a bilateral BI-ALCL diagnosed by cytology. Diagn. Cytopathol. 2016;44:623-627. © 2016 Wiley Periodicals, Inc.

    Depression is a significant public health problem for young adults of college age, and negative life events exacerbate risk. Not all individuals who experience negative life events, however, report depressive symptoms, perhaps owing to protective characteristics. We examined one such characteristic, trait hope, a goal-oriented construct, as a potential moderator of the association between negative life events and depressive symptoms in an ethnically diverse sample of 386 college students. In support of our hypotheses, negative life events were significantly associated with greater levels of depressive symptoms, and higher levels of hope attenuated this relationship, such that those with greater hope reported fewer depressive symptoms related to potentially traumatic events. The moderating effect of hope did not differ across ethnic groups. Our findings have implications for managing the sequelae of negative life events, including depression. Cognitive-behavioural interventions tailored to help young adults identify and attain important life goals might help to overcome psychopathology associated with life stress.

    This exploratory study focuses on the mental health (MH) and caregiving experience of carers of adolescents with Bulimia Nervosa (BN)/Eating Disorder not otherwise specified (EDNOS), aiming to determine: levels of MH problems in carers and if a negative experience of caregiving predicts carer MH status and which factors predict a negative experience of caregiving. Hundred and twelve carers and 68 adolescents with BN/EDNOS completed self-report measures (General Health Questionnaire, Experience of Caregiving Inventory, Level of Expressed Emotion, Self-report Family Inventory, Inventory of Interpersonal Problems). Over half of the carers reported some MH problems and a minority (5.4%) were experiencing considerable difficulties. A negative experience of caregiving predicted carer MH status. Higher weekly contact hours and patient ratings of expressed emotion (EE) predicted a negative experience of caregiving. Interventions focusing on reducing EE and contact hours could prove beneficial for both patient and caregiver outcomes. 2006 by Wiley Periodicals, Inc.

    Background The reasons for increasing rates of bilateral mastectomy for unilateral breast cancer are incompletely understood and associations of disease stage with bilateral surgery have been inconsistent. We examined associations of clinical and sociodemographic factors, including stage, with surgery type and reconstruction receipt among women with breast cancer. Patients/Methods We surveyed a diverse population-based sample of women from northern California cancer registries with stage 0–III breast cancer diagnosed during 2010–2011 (participation rate=68.5%). Using multinomial logistic regression, we examined factors associated with bilateral and unilateral mastectomy (vs. breast conservation [BCS]), adjusting for tumor and sociodemographic characteristics. In a second model, we examined factors associated with reconstruction for mastectomy-treated patients. Results Among 487 participants, 58% had BCS, 32% had unilateral mastectomy, and 10% underwent bilateral mastectomy. In adjusted analyses, women with stage III (vs. stage 0) cancers had higher odds of bilateral mastectomy (odds ratio [O.R]=8.28; 95% Confidence Interval=2.32–29.50); women with stage II and III (vs. stage 0) disease had higher odds of unilateral mastectomy. Higher (vs. lower) income was also associated with bilateral mastectomy, while age ≥60 (vs. mastectomy-treated patients (n=206), bilateral mastectomy, unmarried status, higher education and income were all associated with reconstruction (Psmastectomy despite a lack of clear medical benefit, raising concern for over-treatment. Our findings highlight the need for interventions to assure women are making informed surgical decisions. PMID:26410475

    There has been substantial renewed interest in negative thermal expansion following the discovery that cubic ZrW{sub 2}O{sub 8} contracts over a temperature range in excess of 1000 K. Substances of many different kinds show negative thermal expansion, especially at low temperatures. In this article we review the underlying thermodynamics, emphasizing the roles of thermal stress and elasticity. We also discuss vibrational and non-vibrational mechanisms operating on the atomic scale that are responsible for negative expansion, both isotropic and anisotropic, in a wide range of materials.

This essay examines the “negative anthropology” of the early Frankfurt School by asking how Max Horkheimer, Theodor W. Adorno and Ulrich Sonnemann engage with the question “What is man?” Negative anthropology turns out to be more than the critique of philosophical anthropology: By understanding the human being as the ensemble of what it is not, negative anthropology avoids the predi...

  17. Negative transverse impedance

    Energy Technology Data Exchange (ETDEWEB)

    Chou, W.

    1989-06-12

    Recently, measurements in the SPS show that the coherent tune shift in the horizontal direction has positive values whereas that in the vertical direction has negative ones. Thus the existence of negative transverse impedance gets confirmed in a real machine. This stimulates us to start a new round of systematic studies on this interesting phenomenon. The results obtained from our computer simulations are presented in this note. Our simulations demonstrate that the negative transverse impedance may appear when the rotational symmetry embedded in a discontinuity is broken, and that the geometries that we have studies may be the source of the positive horizontal tune shift measured in the SPS.

    Full Text Available We investigated bacterial findings from intraoperative tissue samples taken during revision due to infection after total hip arthroplasty (THA. The aim was to investigate whether the susceptibility patterns changed during the period from 1993 through 2007. Reported revisions due to infection in the Norwegian Arthroplasty Register (NAR were identified, and 10 representative hospitals in Norway were visited. All relevant information on patients reported to the NAR for a revision due to infection, including bacteriological findings, was collected from the medical records. A total of 278 revision surgeries with bacterial growth in more than 2 samples were identified and included. Differences between three 5-year time periods were tested by the chi-square test for linear trend. The most frequent isolates were coagulase-negative staphylococci (CoNS (41%, 113/278 and Staphylococcus aureus (19%, 53/278. The proportion of CoNS resistant to the methicillin-group increased from 57% (16/28 in the first period, 1993–1997, to 84% (52/62 in the last period, 2003–2007 (P = 0.003. There was also significant increase in resistance for CoNS to cotrimoxazole, quinolones, clindamycin, and macrolides. All S. aureus isolates were sensitive to both the methicillin-group and the aminoglycosides. For the other bacteria identified no changes in susceptibility patterns were found.

  12. The role of multiple negative social relationships in inflammatory cytokine responses to a laboratory stressor

    2015-06-01

    Full Text Available The present study examined the unique impact of perceived negativity in multiple social relationships on endocrine and inflammatory responses to a laboratory stressor. Via hierarchical cluster analysis, those who reported negative social exchanges across relationships with a romantic partner, family, and their closest friend had higher mean IL-6 across time and a greater increase in TNF-α from 15 min to 75 min post stress. Those who reported negative social exchanges across relationships with roommates, family, and their closest friend showed greater IL-6 responses to stress. Differences in mean IL-6 were accounted for by either depressed mood or hostility, whereas differences in the cytokine stress responses remained significant after controlling for those factors. Overall, this research provides preliminary evidence to suggest that having multiple negative relationships may exacerbate acute inflammatory responses to a laboratory stressor independent of hostility and depressed mood.

    According to the“two-component model of impression management theory, impression motivation influences im⁃pression construction. Based on the data of 217 research samples of 55 listing corporations from 2009 to 2015, this paper exam⁃ines the use of indirect impression management after the negative reports in China. The results show that negative reports stim⁃ulate organizational impression management motivation and prompt the firm to increase the number of indirect impression man⁃agement tactics to repair the image. Specifically, the firm is likely to react with a larger increase in indirect impression manage⁃ment tactics when the firm has a higher reputation, or when the firm engaged in more indirect impression management tactics before the boycott;The pro-threat impression management tactics play a significant negative moderating role in the relation⁃ship of firm reputation and post-threat impression management tactics;The firm will use most of indirect impression manage⁃ment strategy in the face of the defensive negative reports. These findings provide inspirations for the implementation of reputa⁃tion restoration strategy after negative reports.%根据印象管理理论的“双组件”模型,印象动机影响印象构建。文章基于55个上市公司的217个研究样本2009-2015年的数据,考察了我国企业负面报道后间接印象管理使用情况。结果表明,负面报道刺激组织印象管理动机,促使其增加间接印象管理策略的数目来修复形象。具体表现为,企业社会地位越高、负面报道前的印象管理策略越多,负面报道后的间接印象管理策略越多;负面报道前的印象管理策略对企业社会地位与负面报道后印象管理策略之间的关系起到了显著的负向调节作用;面对可辩解型负面报道时,企业会使用较多数目的间接印象管理策略。这些发现为组织负面报道后实施形象修复性策略提供了启示。

  14. Positive and negative expressions of shyness in toddlers: are they related to anxiety in the same way?

    Science.gov (United States)

    Colonnesi, Cristina; Napoleone, Elisa; Bögels, Susan M

    2014-04-01

    Shyness has generally been investigated as a negative and unpleasant emotional state, strongly related to social anxiety and loneliness. However, recent evidence has suggested that shyness may have a positive and socially adaptive form. We examined whether the positive expression of shyness differs from the negative expression of shyness during toddlerhood, and whether a negative relation to anxiety exists. Participants were 30-month-old children (N=102; 56 girls) who were asked to mimic animal sounds with a novel person (performance) and then to watch their performance (self-watching). Their expression of pleasure (positive reactions) and distress (negative reactions), as well as their positive and negative expressions of shyness, were coded. Children's temperamental level of shyness, sociability, and anxiety were measured with parent-reported questionnaires. Toddlers produced more positive and negative displays of shyness in the performance task than in the self-watching task. Children's positive expression of shyness was associated with lower parent-reported anxiety and higher sociability. Negative reactions, but not negative shyness, were related to children's higher anxiety levels and lower sociability. Multiple linear regression analyses confirmed a negative predictive role of the positive expression of shyness on anxiety. These results suggest that the positive expression of shyness can regulate early anxiety symptoms and already serves a social function in interpersonal interactions in early childhood.

  16. Covariant holographic entanglement negativity

    Chaturvedi, Pankaj; Sengupta, Gautam

    2016-01-01

    We conjecture a holographic prescription for the covariant entanglement negativity of $d$-dimensional conformal field theories dual to non static bulk $AdS_{d+1}$ gravitational configurations in the framework of the $AdS/CFT$ correspondence. Application of our conjecture to a $AdS_3/CFT_2$ scenario involving bulk rotating BTZ black holes exactly reproduces the entanglement negativity of the corresponding $(1+1)$ dimensional conformal field theories and precisely captures the distillable quantum entanglement. Interestingly our conjecture for the scenario involving dual bulk extremal rotating BTZ black holes also accurately leads to the entanglement negativity for the chiral half of the corresponding $(1+1)$ dimensional conformal field theory at zero temperature.

    as such may be more or less central to the meaning of the utterance. The present paper investigates the role of morphosyntactic and prosodic prominence as well as register and social setting on the interpretation of negations. It seems plausible to expect that if the negation as such is central to the meaning...... common in certain social context or genres, while polemic negations are more likely to come up in other genres and social settings. Previous studies have shown a relation between articulatory prominence and register, which may further inform the analysis. Hence, the paper investigates how articulatory...... prominence and register may either work in concert or oppose each other with respect to the cues they provide for the interpretation....

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O edema pulmonar por pressão negativa após obstrução de via aérea é atualmente uma entidade bem descrita, porém pouco diagnosticada e com poucos casos relatados. O objetivo deste artigo foi relatar um caso de edema pulmonar por pressão negativa (EPPN após extubação traqueal com sucesso terapêutico, após uso de ventilação mecânica não-invasiva com pressão positiva. RELATO DO CASO: Paciente do sexo feminino, 22 anos, foi submetida à colecistectomia aberta. Os exames pré-operatórios encontravam-se sem alterações. Imediatamente após extubação a paciente apresentou dispnéia súbita e crepitações pulmonares. Foi iniciado tratamento para edema agudo de pulmão com oxigenoterapia sob máscara de Venturi, elevação do tórax e diurético. A paciente foi encaminhada a UTI devido a falha no tratamento. Ao chegar a UTI foi iniciada ventilação mecânica não-invasiva (VMNI com pressão de suporte (15 cmH2O e pressão expiratória final positiva (5 cmH2O com resolução dos sintomas. A paciente foi mantida em observação por mais 24 horas depois do evento com boas condições e recebeu alta para o quarto sem sintomas. CONCLUSÕES: O EPPN é uma entidade de difícil diagnóstico e deverá ser observada sempre que os pacientes evoluem com sinais e sintomas de insuficiência respiratória pós-extubação. Esta paciente se beneficiou de VMNI, mas caso haja falha terapêutica, a intubação traqueal e o suporte ventilatório mecânico invasivo deverão ser instituídos para melhor oxigenação dos pacientes.BACKGROUND AND OBJECTIVES: Negative pressure pulmonary edema after acute upper airway obstruction is a well-described event, thought infrequently diagnosed and reported.

  19. Negative Probabilities and Contextuality

    CERN Document Server

    de Barros, J Acacio; Oas, Gary

    2015-01-01

    There has been a growing interest, both in physics and psychology, in understanding contextuality in experimentally observed quantities. Different approaches have been proposed to deal with contextual systems, and a promising one is contextuality-by-default, put forth by Dzhafarov and Kujala. The goal of this paper is to present a tutorial on a different approach: negative probabilities. We do so by presenting the overall theory of negative probabilities in a way that is consistent with contextuality-by-default and by examining with this theory some simple examples where contextuality appears, both in physics and psychology.

  20. Task reports on developing techniques for scattering by 3D composite structures and to generate new solutions in diffraction theory using higher order boundary conditions

    Science.gov (United States)

    Volakis, John L.

    1991-01-01

    There are two tasks described in this report. First, an extension of a two dimensional formulation is presented for a three dimensional body of revolution. A Fourier series expansion of the vector electric and magnetic fields is employed to reduce the dimensionality of the system, and an exact boundary condition is employed to terminate the mesh. The mesh termination boundary is chosen such that it leads to convolutional boundary operators for low O(n) memory demand. Second, rigorous uniform geometrical theory of diffraction (UTD) diffraction coefficients are presented for a coated convex cylinder simulated with generalized impedance boundary conditions. Ray solutions are obtained which remain valid in the transition region and reduce uniformly those in the deep lit and shadow regions. A uniform asymptotic solution is also presented for observations in the close vicinity of the cylinder.

  1. Negative emotions and coronary heart disease: causally related or merely coexistent? A review.

    Science.gov (United States)

    Smith, D F

    2001-02-01

    Negative emotions have been claimed to be a cause of coronary heart disease (CHD) as well as a consequence of cardiovascular disorders. Early case studies of cardiac disorders of soldiers in battle drew attention to the possibility that strong negative emotional states could cause CHD. Subsequent reports of reactions to natural disasters supported the notion that intense negative emotions could precipitate somatic disorders such as CHD. Since then, numerous studies have investigated relations between negative emotions and CHD. Over the years, retrospective studies have found, for example, that negative emotions are often present before the occurrence of CHD. Cross-sectional studies have indicated that symptoms of depression and anxiety are often present in CHD patients. Prospective studies have shown that the likelihood of CHD tends to be higher for people with negative emotions than for those without them. The main symptoms of negative emotional states that seem to be most closely associated with CHD are nervousness, getting easily upset, feeling fatigue, being indecisive, having sleep disturbances, being usually worried about something, and feeling that others would be better off if oneself were dead. Although the findings appear to support the notion of causal connections between negative emotions and CHD, they fail to provide conclusive proof of such relations. An alternative explanation that could also account for the findings is simply that negative emotions and CHD often coexist.

    A drug interaction leading to higher exposure to cyclosporine DRUGS IMPLICATED: Cyclosporine and ticagrelor THE PATIENT: A 49-year old man with a stable renal graft, managed with cyclosporine with stable trough blood concentrations for several years, was treated with ticagrelor for unstable angina pectoris EVIDENCE THAT LINKS THE DRUG TO THE EVENT: The timeline was consistent with the appearance of an interaction, the interaction was confirmed by an increase in trough concentration of cyclosporine, and there were no alternative causes that by themselves could have caused the increase in cyclosporine exposure MANAGEMENT: Cessation of ticagrelor MECHANISM: Inhibition of CYP3A4 and P-glycoprotein by ticagrelor IMPLICATIONS FOR THERAPY: Clinicians should be aware of this potential interaction as ticagrelor is frequently prescribed in individuals using cyclosporine. Close monitoring of cyclosporine serum concentrations is warranted to avoid overdosing of cyclosporine. A pharmacokinetic study is needed to further examine the probable interaction between cyclosporine and ticagrelor. This article is protected by copyright. All rights reserved.

    1997-10-01

    With the ban of the refrigerant R22, beginning on January 1st, 2000, there will result a need for the development of alternative refrigerators for the refrigeration at temperatures from -50 C to -20 C. During the finished research project it should be tested if Stirling refrigeration plants could efficiently produce cold in that temperature range, because they can use the working gas helium without any environmental influence. Two types of Stirling refrigeration plants have been tested. For one type there should be used a new concept of transferring heat out and into the machine. In this concept a heat carrier should be atomized into the working spaces of the Stirling refrigeration machine to receive a higher coefficient of performance. The other type is a usual Stirling refrigeration machine with heat exchangers for the heat removal and supply. The calculated coefficients of performance in the above mentioned temperature range reach the level of usual R22-refrigeration systems for both types of Stirling refrigeration plants. Comparing both types higher coefficients of performance could be calculated for the machine with heat carrier injection. But during the atmomizing experiments it came out that a realisation of this type of machine is coupled with a high need of instrumentation. Compared to that the machine with heat exchangers is easily constructed. For this reason that kind of machine is built at present however for other applications. During the project there could be found a very interesting and as well important application for Stirling refrigeration plants that produce cold in a temperature range from -50 C to -20 C. This is the low-temperature cooling in supermarkets. For that application a stirling refrigeration plant shows a number of benefits, so that a machine put on the market could be successful. (orig.)

    This longitudinal study applied a stress and coping model to examine the differential pathways of perceived positive and negative health behavior changes. Participants with congestive heart failure completed self-report measures of psychological resources, coping strategies, and perceived behavior changes and were assessed again 6 months later. Patients with higher positive affect and spiritual well-being reported more positive health behavior changes over time, effects mediated by approach coping. Alternatively, patients with lower psychological resources reported more negative behavior changes over time, effects mediated by avoidance coping. The results suggest that different psychological resources are related to different types of coping which, in turn, are associated with perceived positive or negative changes in health behavior over time.

    Triple-negative breast carcinomas (TNBCs) comprise approximately 15% to 20% of breast cancers. Accurate assessment of tumor estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) status is an essential part of classifying tumors into this group. As a group, these tumors are associated with poor clinical outcomes and have been shown to exhibit an increased propensity for hematogenous metastasis to the brain and lungs. Many TNBCs, particularly ductal, not otherwise specified (NOS), and metaplastic carcinomas, show an overlapping characteristic gene expression pattern when evaluated by cDNA microarrays. This group has been termed basal-like because of the similarity with normal breast basal/myoepithelial cells including basal cytokeratin expression and lack of hormone receptor and HER2 expression. The array data have been used to develop multiple immunohistochemical surrogates to identify basal-like tumors in formalin-fixed, paraffin-embedded tissues, most employing basal cytokeratins and epidermal growth factor receptor. Currently, there is no international consensus on biomarkers used to identify tumors as basal-like, and the routine use of the term basal-like in surgical pathology reports is premature. Tumor morphologic features associated with triple-negative status include Nottingham grade 3 with high mitotic rate, pushing border of invasion, geographic tumor necrosis, solid/sheet-like growth pattern, lymphocytic infiltrate, and large central acellular zone. Most breast cancers arising in patients who have a germ-line BRCA1 mutation show similar histologic features and a triple-negative phenotype. Not all TNBCs are associated with an unfavorable prognosis, drawing attention to the heterogeneity of this tumor group and the continued need to link tumor morphology and grade with triple-negative status. This article focuses on histopathology, molecular characterization, carcinogenesis, clinical behavior, and treatment of these

  8. Negative magnetoresistivity in holography

    Negative magnetoresistivity is a special magnetotransport property associated with chiral anomaly in four dimensional chiral anomalous systems, which refers to the transport behavior that the DC longitudinal magnetoresistivity decreases with increasing magnetic field. We calculate the longitudinal magnetoconductivity in the presence of backreactions of the magnetic field to gravity in holographic zero charge and axial charge density systems with and without axial charge dissipation. In the absence of axial charge dissipation, we find that the quantum critical conductivity grows with increasing magnetic field when the backreaction strength is larger than a critical value, in contrast to the monotonically decreasing behavior of quantum critical conductivity in the probe limit. With axial charge dissipation, we find the negative magnetoresistivity behavior. The DC longitudinal magnetoconductivity scales as $B$ in the large magnetic field limit, which deviates from the exact $B^2$ scaling of the probe limit resul...

    Objective: Research consistently shows a positive association between racial discrimination and problematic alcohol use among African Americans, but little is known about the micro-processes linking this pernicious form of stress to drinking. One possibility is that the cumulative effects of discrimination increase individuals’ likelihood of negative-mood–related drinking. In the current study, we examined whether individual differences in lifetime perceived racial discrimination among African American college students moderate relations between daily negative moods and evening alcohol consumption in both social and nonsocial contexts. Method: Data came from an online daily diary study of 441 African Americans (58% female) enrolled at a historically black college/university. Lifetime discrimination was measured at baseline. For 30 days, students reported the number of drinks they consumed the night before both socially and nonsocially, as well as their daytime level of negative mood. Results: In support of the hypotheses, only men who reported higher (vs. lower) lifetime discrimination showed a positive association between daily negative mood and that evening’s level of nonsocial drinking. Contrary to expectation, women who reported higher (vs. lower) discrimination showed a negative association between daily negative mood and nonsocial drinking. Neither daily negative mood nor lifetime discrimination predicted level of social drinking. Conclusions: These findings provide further evidence that the cumulative impact of racial discrimination may produce a vulnerability to negative-mood–related drinking—but only for African American men. Importantly, these effects emerged only for nonsocial drinking, which may further explain the robust association between discrimination and problematic alcohol use. PMID:25785798

  10. Negative Emissions Technology

    Although `negative emissions' of carbon dioxide need not, in principle, involve use of biological processes to draw carbon out of the atmosphere, such `agricultural' sequestration' is the only known way to remove carbon from the atmosphere on time scales comparable to the time scale for anthropogenic increases in carbon emissions. In order to maintain the `negative emissions' the biomass must be used in such a way that the resulting carbon dioxide is separated and permanently sequestered. Two options for sequestration are in the topsoil and via geologic carbon sequestration. The former has multiple benefits, but the latter also is needed. Thus, although geologic carbon sequestration is viewed skeptically by some environmentalists as simply a way to keep using fossil fuels---it may be a key part of reversing accelerating climate forcing if rapid climate change is beginning to occur. I will first review the general approach of agricultural sequestration combined with use of resulting biofuels in a way that permits carbon separation and then geologic sequestration as a negative emissions technology. Then I discuss the process that is the focus of my company---the EPRIDA cycle. If deployed at a sufficiently large scale, it could reverse the increase in CO2 concentrations. I also estimate of benefits --carbon and other---of large scale deployment of negative emissions technologies. For example, using the EPRIDA cycle by planting and soil sequestering carbon in an area abut In 3X the size of Texas would remove the amount of carbon that is being accumulated worldwide each year. In addition to the atmospheric carbon removal, the EPRIDA approach also counters the depletion of carbon in the soil---increasing topsoil and its fertility; reduces the excess nitrogen in the water by eliminating the need for ammonium nitrate fertilizer and reduces fossil fuel reliance by providing biofuel and avoiding natural gas based fertilizer production.

    Greater levels of conscientiousness have been associated with lower levels of negative affect. We focus on one mechanism through which conscientiousness may decrease negative affect: effective emotion regulation, as reflected by greater recovery from negative stimuli. In 273 adults who were 35-85 years old, we collected self-report measures of personality including conscientiousness and its self-control facet, followed on average 2 years later by psychophysiological measures of emotional reactivity and recovery. Among middle-aged adults (35-65 years old), the measures of conscientiousness and self-control predicted greater recovery from, but not reactivity to, negative emotional stimuli. The effect of conscientiousness and self-control on recovery was not driven by other personality variables or by greater task adherence on the part of high conscientiousness individuals. In addition, the effect was specific to negative emotional stimuli and did not hold for neutral or positive emotional stimuli.

    2013-01-01

    The concept of negative temperatures has occasionally been used in connection with quantum systems. A recent example of this sort is reported in the paper of S. Braun et al. [Science 339,52 (2013)], where an attractively interacting ensemble of ultracold atoms is investigated experimentally and found to correspond to a negative-temperature system since the entropy decreases with increasing energy at the high end of the energy spectrum. As the authors suggest, it would be of interest to investigate whether a suitable generalization of standard cosmological theory could be helpful, in order to elucidate the observed accelerated expansion of the universe usually explained in terms of a positive tensile stress (negative pressure). In the present note we take up this basic idea and investigate a generalization of the standard viscous cosmological theory, not by admitting negative temperatures but instead by letting the bulk viscosity take negative values. Evidently, such an approach breaks standard thermodynamics,...

    2014-06-01

    The current study investigated whether negative body evaluation predicts women's overestimation of negative social feedback related to their own body (i.e., covariation bias). Sixty-five female university students completed a computer task where photos of their own body, of a control woman's body, and of a neutral object, were followed by nonverbal social feedback (i.e., facial crowds with equal numbers of negative, positive, and neutral faces). Afterward, women estimated the percentage of negative, positive, and neutral social feedback that followed their own body, the control woman's body, and the neutral object. The findings provided evidence for a covariation bias: negative body evaluation predicted higher estimates of negative social feedback for women's own body, but not for the other stimuli. Additionally, the covariation bias was not explained by differences in how women interpreted the social feedback (the facial stimuli). Clinical implications of the covariation bias to body image are discussed.

    2017-01-01

    Introduction Breast carcinoma is one of the most common malignancies affecting women in developing countries. Molecular studies of breast carcinoma have classified the tumour based on the immunohistochemical staining into 4 subtypes, such as Luminal A, Luminal B, HER2/neu Positive and Triple Negative Breast Carcinoma (TNBC). TNBCs are reported to have an aggressive behaviour and wide metastasis, leading to selective treatment outcomes. Aim The aim was to study the clinicopathological features such as age, site, tumour size, histopathological type, histologic grade, lymph node status, stage and treatment outcomes of triple negative breast carcinoma. Materials and Methods A retrospective study was conducted on 108 cases of breast carcinoma received during the period of 2 years. The tumour was classified based on immunohistochemical staining into four subtypes. The clinicopathological details, histomorphological and immunohistochemical features of TNBC were studied. Results Of the 108 patients, 34 patients were diagnosed as TNBC. The average age at presentation was 48 years. Most of the cases showed Nottingham Modification of Scarff Bloom-Richardson (NMBR) grade 3 (55.9%) and stage II (67.6%). Ly-mph node metastasis was seen in 50% of cases. Infiltrating ductal carcinoma (not otherwise specified) type (91.2%) was the most common histological type. Among the other subtypes, Luminal A carcinoma was the most common (36.1%), followed by TNBC (31.5%) and HER2/neu positive carcinomas (28.7%). Compared to the other types of tumours, TNBC showed the most frequent distant lymph node metastasis (50%) when compared to luminal A (38.5%), luminal B (25%), HER2/neu positive (48.4%). Unlike the other types of tumours, TNBC were mostly high-grade. Conclusion TNBC have an aggressive behaviour compared to other subtypes with higher NMBR grade, nuclear pleomorphism, high mitotic rate and lymph node metastasis. PMID:28273970

    Full Text Available Engineered materials composed of designed inclusions can exhibit exotic and unique electromagnetic properties not inherent in the individual constituent components. These artificially structured composites, known as metamaterials, have the potential to fill critical voids in the electromagnetic spectrum where material response is limited and enable the construction of novel devices. Recently, metamaterials that display negative refractive index – a property not found in any known naturally occurring material – have drawn significant scientific interest, underscoring the remarkable potential of metamaterials to facilitate new developments in electromagnetism.

    This study was designed to investigate environmental colonisation in Algerian hospitals by carbapenem-resistant Gram-negative bacilli (GNB), including molecular characterisation of their resistance, and to perform a comparative molecular analysis between clinical and environmental strains. GNB isolated from hospitalised patients and the hospital environment were identified using microbiological methods and matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF/MS). Antibiotic susceptibility testing was performed by disk diffusion and Etest methods. Carbapenemase- and extended-spectrum β-lactamase (ESBL)-encoding genes were searched for using PCR and sequencing. Clonality of the environmental and clinical strains was assessed by multilocus sequencing typing (MLST). A total of 32 carbapenem-resistant GNB were isolated, including 16 (29%) of 56 multidrug-resistant (MDR) GNB from clinical specimens and 16 (48%) of 33 MDR-GNB from inanimate surfaces. Of the 32 carbapenem-resistant isolates, 14 produced a carbapenemase. The blaOXA-48 gene was detected both in clinical and surface isolates of Klebsiella pneumoniae (n=3) and Enterobacter cloacae (n=2). Clinical and surface isolates of Acinetobacter baumannii were found to produce the carbapenemases NDM-1 (7 isolates) and OXA-23 (2 isolates). MLST revealed clonal diversity and a relationship between environmental and clinical strains with identical sequence types. Here we report the first description of an OXA-48-producing E. cloacae isolate in Algeria. We also highlight the important role of inanimate surfaces in the spread of carbapenem-resistant bacteria and the emergence of nosocomial infections.

  18. Perceptual Negativity Predicts Greater Reactivity to Negative Events in Daily Life.

    2013-11-01

    Reinforcement sensitivity theory includes the idea that people differ in their sensitivity to negative events, but relevant process-based assessments have not been developed. The present studies assessed sensitivity to negative events in terms of the extent to which negative word stimuli were perceived to be larger than neutral word stimuli. There was a general tendency to overestimate the size of negative relative to neutral words, but individuals differed substantially in this form of what is termed perceptual negativity. Of more importance, two studies (total N = 151) found systematic relationships between individual differences in perceptual negativity and reactivity to negative events in daily diary protocols. Study 1 found that within-person variations in the occurrence of daily negative events undermined goal-related optimism to a greater extent at higher, relative to lower, levels of perceptual negativity. Study 2 conceptually replicated this interaction in the context of within-person associations between the occurrence of daily negative events and antisocial behavior. These findings are important in advancing reinforcement sensitivity theory, in operationalizing a particular component of it, and in extending it to reactivity processes in daily life.

  19. Negative Average Preference Utilitarianism

    Full Text Available For many philosophers working in the area of Population Ethics, it seems that either they have to confront the Repugnant Conclusion (where they are forced to the conclusion of creating massive amounts of lives barely worth living, or they have to confront the Non-Identity Problem (where no one is seemingly harmed as their existence is dependent on the “harmful” event that took place. To them it seems there is no escape, they either have to face one problem or the other. However, there is a way around this, allowing us to escape the Repugnant Conclusion, by using what I will call Negative Average Preference Utilitarianism (NAPU – which though similar to anti-frustrationism, has some important differences in practice. Current “positive” forms of utilitarianism have struggled to deal with the Repugnant Conclusion, as their theory actually entails this conclusion; however, it seems that a form of Negative Average Preference Utilitarianism (NAPU easily escapes this dilemma (it never even arises within it.

    2002-01-01

    We investigate cosmological evolution in models where the effective potential V(\\phi) may become negative for some values of the field \\phi. Phase portraits of such theories in space of variables (\\phi,\\dot\\phi,H) have several qualitatively new features as compared with phase portraits in the theories with V(\\phi) > 0. Cosmological evolution in models with potentials with a "stable" minimum at V(\\phi)<0 is similar in some respects to the evolution in models with potentials unbounded from below. Instead of reaching an AdS regime dominated by the negative vacuum energy, the universe reaches a turning point where its energy density vanishes, and then it contracts to a singularity with properties that are practically independent of V(\\phi). We apply our methods to investigation of the recently proposed cyclic universe scenario. We show that in addition to the singularity problem there are other problems that need to be resolved in order to realize a cyclic regime in this scenario. We propose several modificati...

  3. Polarized negative ions

    Haeberli, W.

    1981-04-01

    This paper presents a survey of methods, commonly in use or under development, to produce beams of polarized negative ions for injection into accelerators. A short summary recalls how the hyperfine interaction is used to obtain nuclear polarization in beams of atoms. Atomic-beam sources for light ions are discussed. If the best presently known techniques are incorporated in all stages of the source, polarized H/sup -/ and D/sup -/ beams in excess of 10 ..mu..A can probably be achieved. Production of polarized ions from fast (keV) beams of polarized atoms is treated separately for atoms in the H(25) excited state (Lamb-Shift source) and atoms in the H(1S) ground state. The negative ion beam from Lamb-Shift sources has reached a plateau just above 1 ..mu..A, but this beam current is adequate for many applications and the somewhat lower beam current is compensated by other desirable characteristics. Sources using fast polarized ground state atoms are in a stage of intense development. The next sections summarize production of polarized heavy ions by the atomic beam method, which is well established, and by optical pumping, which has recently been demonstrated to yield very large nuclear polarization. A short discussion of proposed ion sources for polarized /sup 3/He/sup -/ ions is followed by some concluding remarks.

    Concern with real or imagined defect in physical appearance can become a major preoccupation during adolescence and young adult years. This is because, changes of puberty, rapid physical growth, and resulting sexual maturation that characterizes this age can trigger feelings of self-consciousness and awkwardness about body-image perceptions. In addition, the "perfect" body-image as dictated in the social culture could become a measure of self-worth, and this is capable of triggering negative self-image and social anxiety among adolescents. This study seeks to assess the incidence of negative self-image (preoccupation with real or imagined defect in physical appearance) and social anxiety characterized by fear of negative evaluation, among adolescents and young adults. Samples of 329 participants in the age range of 16-25 were drawn from the first and second years students of Federal University Wukari and University of Lagos, Nigeria. Participants completed a socio-demographic data sheet as well as NSII (Negative Self-Image Inventory) and revalidated version of FNE (Fear of Negative Evaluation). Findings revealed that there is a correlation between negative self-image and fear of negative evaluation; males manifested higher symptoms of negative self-image than females; young adults aged 21-25 presented higher negative self-image that those aged 16-20, adolescents and young adults from Lagos metropolis experience higher manifestation of fear of negative evaluation than those from Wukari axis. This study therefore adds to knowledge in this area.

    Full Text Available Abstract Background Negation occurs frequently in scientific literature, especially in biomedical literature. It has previously been reported that around 13% of sentences found in biomedical research articles contain negation. Historically, the main motivation for identifying negated events has been to ensure their exclusion from lists of extracted interactions. However, recently, there has been a growing interest in negative results, which has resulted in negation detection being identified as a key challenge in biomedical relation extraction. In this article, we focus on the problem of identifying negated bio-events, given gold standard event annotations. Results We have conducted a detailed analysis of three open access bio-event corpora containing negation information (i.e., GENIA Event, BioInfer and BioNLP’09 ST, and have identified the main types of negated bio-events. We have analysed the key aspects of a machine learning solution to the problem of detecting negated events, including selection of negation cues, feature engineering and the choice of learning algorithm. Combining the best solutions for each aspect of the problem, we propose a novel framework for the identification of negated bio-events. We have evaluated our system on each of the three open access corpora mentioned above. The performance of the system significantly surpasses the best results previously reported on the BioNLP’09 ST corpus, and achieves even better results on the GENIA Event and BioInfer corpora, both of which contain more varied and complex events.

The ability to identify negated events is a key performance element for these systems. We have conducted the first detailed study on the analysis and identification of negated bio-events.

  12. Micro-syntactic variation in American English Negative Concord

    Directory of Open Access Journals (Sweden)

    Frances Blanchette

    2017-07-01

    Full Text Available This paper presents a series of quantitative gradient acceptability judgment studies of English negative sentences. Adult native speakers of American English recruited via Amazon’s Mechanical Turk were asked to rate sentences on a scale of 1 to 7 on the basis of their naturalness. The main study compares sentences with the marker 'n’t 'and either a negative object (e.g. ‘John didn’t eat nothing’ or a negative subject in canonical position (‘nobody didn’t eat’. Each sentence type has two possible interpretations, one in which the two negatives contribute a single semantic negation, the so-called Negative Concord reading, and another in which the two negations yield a semantic Double Negation logically equivalent to an affirmative. While mean acceptability ratings were below the median for all items, statistical analyses of the gradient data revealed that speakers prefer Negative Concord over Double Negation readings for sentences with negative objects. To rule out a processing explanation for the preference for negative objects over sentence initial negatives, a follow-up study tested the acceptability of sentences with a single negative subject or object and no negative marker. This revealed a preference for subjects, suggesting that the object preference in the two negatives study is a true grammatical effect. A third study revealed that Double Negation constructions are unacceptable overall even in explicit denial contexts, and a fourth study added Negative Auxiliary Inversion constructions (e.g. ‘Didn’t nobody eat’, to compare three types of Negative Concord. The results of all four studies are argued to reveal an English grammar that generates both Negative Concord and Double Negation, and in which Negative Concord is generated despite its unacceptability and reported absence in usage.

    We assessed the effects of beliefs about state HIV criminal law on condomless anal sex (CAS criminal law(s) or where a HIV-related arrest, prosecution, or sentence enhancement (APSE) had occurred. Three-quarters of MSM reported that they were unsure of the law in their state. Men who believed there was a HIV law in their state but lived in states without any or a sex-specific HIV criminal law(s) had higher probabilities of CAS compared to those who were unsure of their state's law; men who believed there was a HIV law in their state and lived in a state where an APSE had occurred had higher probabilities of CAS compared to those who were unsure of their state's law. Correct knowledge of state law was not associated with CAS. Findings suggest that HIV criminal laws have little or counter-productive effects on MSM's risk behavior.

    Physical fields, such as gravity and electromagnetic field, are interpreted as results from rearrangement of vacuum particles to get the equilibrium of net charge density and net mass density in 4-dimensional complex space. Then, both fields should interact to each other in that physical interaction is considered as a field-to-field interaction. Hence, Mass-Charge interaction is introduced with primitive-virtual negative charge defined for the mass. With the concept of Mass-Charge interaction electric equilibrium of the earth is discussed, especially about the electric field and magnetic field of the earth. For unsettled phenomena related with the earth's gravity, such as antigravity phenomenon, gravity anomalies during the solar eclipses, the connection between geomagnetic storms and earthquakes, etc., possible explanations are discussed.

The precise diagnosis requires detailed clinical examination and electrophysiological findings. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17-18 years of age. Clinical and electrophysiological protocols were detailed. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB. This diagnosis was confirmed by genetic studies. CSNB is interesting to study because through electrophysiological findings, it enables a better understanding of the physiology of neural transmission in the outer part of the retina.Keywords: Congenital nystagmus, negative electroretinography, congenital night stationary blindness

    Studies on brain-evoked potential and contingent negative variation (CNV) in mood disorder remain controversial. To date, no CNV difference between unipolar and bipolar depression has been reported. Brain-evoked potentials were measured in the present study to analyze CNV in three subtypes of mood disorder (mania, unipolar depression, and bipolar depression), and these results were compared with normal controls. In the mania group, CNV amplitude B was greater than in controls, and the depression group exhibited lower CNV amplitude B and smaller A-S'2 area, and prolonged post-imperative negative variation latency. The CNV comparison between unipolar and bipolar depression found that the prolonged post-imperative negative variation latency was only in unipolar depression. These results suggest that prolonged post-imperative negative variation latency is a characteristic of unipolar depression, and CNV amplitude change is a state characteristic of mood disorder patients.

    Higher dimensional states (qudits) allow to implement quantum communication schemes of increasing complexity, as e.g. superdense coding. Similarly, qudits allow further research into the fundaments of quantum theory. Here we report on first steps towards the implementation of states with correlated photon pairs in a 2 x 8 dimensional Hilbert space. To this end the photon pairs are prepared in the energy-time basis, as initially proposed in: Using unbalanced interferometers, information can be encoded in the different arrival times of the photon pairs, early and late, as was experimentally realized in. Here, we extend this scheme by proposing and characterizing a scalable multiple time delay interferometer. This interferometer system allows an exponential increase in the dimensionality of the entangled state with only a linear increase in the optical components used. Using the proposed interferometer system, first experimental tests on a two-dimensional state yielded a violation of a Bell inequality by four standard deviations.

    Full Text Available Abstract Background Cannabis is the most widely consumed illicit substance in America, with increasing rates of use. Some theorists tend to link frequency of use with cannabis dependence. Nevertheless, fewer than half of daily cannabis users meet DSM-IV-TR criteria for cannabis dependence. This study seeks to determine whether the negative aspects associated with cannabis use can be explained by a proxy measure of dependence instead of by frequency of use. Results Over 2500 adult daily cannabis users completed an Internet survey consisting of measures of cannabis and other drug use, in addition to measures of commonly reported negative problems resulting from cannabis use. We compared those who met a proxy measure of DSM-IV-TR criteria for cannabis dependence (N = 1111 to those who did not meet the criteria (N = 1770. Cannabis dependent subjects consumed greater amounts of cannabis, alcohol, and a variety of other drugs. They also had lower levels of motivation, happiness, and satisfaction with life, with higher levels of depression and respiratory symptoms. Conclusion Although all of our subjects reported daily use, only those meeting proxy criteria for cannabis dependence reported significant associated problems. Our data suggest that dependence need not arise from daily use, but consuming larger amounts of cannabis and other drugs undoubtedly increases problems.

    To investigate potential predictors of the severity of binge eating disorder (BED), two subtypes of patients with the disorder, a pure dietary subtype and a dietary-negative affect subtype, were identified. This study investigated the relationships between the two subtypes and impulsivity and reinforcement sensitivity. Ninety-two women meeting threshold and subthreshold criteria for BED diagnosis filled out questionnaires to determine eating disorder severity, impulsivity and reinforcement sensitivity before and after participating in an online guided self-help program for BED. Cluster analyses revealed a pure dietary subtype (N=66, 71.7%) and a dietary-negative affect subtype (N=26, 28.3%). Compared to the pure dietary subtype, the dietary-negative affect subtype reported a higher frequency of objective binge episodes, more severe eating disorders, higher urgency scores (defined as a tendency to act rashly in the context of negative affect), a greater sensitivity to punishment, and a higher dropout rate during treatment. These findings suggest that BED patients in the dietary-negative affect subtype exhibit heightened anxiety and are highly impulsive, especially in contexts of negative affect. For these individuals, psychological interventions for BED should focus on inhibiting automatic responses to negative emotions.

    Understanding the emotional risk factors for cigarette smoking in adolescence can greatly inform prevention efforts. The current study examined prospective relationships between 3 affective dimensions--negative mood variability, overall negative mood, and depression---affect-related smoking motives, and future smoking patterns among adolescents. The current study expands on prior research by using real-time methods to assess mood and by focusing on a key developmental transition in smoking behavior: the progression from experimentation or low level, infrequent use to higher use. Ninth- and 10th-grade students (N = 461; 55% girls) provided data on cigarette use at a baseline and follow-up 15-month wave, and also provided ecological momentary assessments of negative moods via palmtop computers for 1 week at each wave. Negative mood was examined via the means of negative mood reports at each wave, and mood variability was examined via the intraindividual standard deviations of negative mood reports at each wave. Depressive symptoms and smoking motives were also assessed. Findings supported a complex self-medication model of smoking escalation in adolescence whereby mood-smoking relationships differed by affect dimension and gender. For girls, greater negative mood variability at baseline significantly predicted rapid escalation in smoking over time, whereas depressive symptoms and overall negative mood were unrelated to girls' smoking patterns. In contrast, overall negative mood significantly predicted boys' smoking escalation among those with affect-related motives for smoking. Results thus suggest that inconsistent mood-smoking relations in past work may be driven by the complex interrelationships among affect vulnerabilities, gender, and smoking patterns.

    There is evidence that women may be less successful when attempting to quit smoking than men. One potential contributory cause of this gender difference is differential craving and stress reactivity to smoking- and negative affect/stress-related cues. The present human laboratory study investigated the effects of gender on reactivity to smoking and negative affect/stress cues by exposing nicotine dependent women (n = 37) and men (n = 53) smokers to two active cue types, each with an associated control cue: (1) in vivo smoking cues and in vivo neutral control cues, and (2) imagery-based negative affect/stress script and a neutral/relaxing control script. Both before and after each cue/script, participants provided subjective reports of smoking-related craving and affective reactions. Heart rate (HR) and skin conductance (SC) responses were also measured. Results indicated that participants reported greater craving and SC in response to smoking versus neutral cues and greater subjective stress in response to the negative affect/stress versus neutral/relaxing script. With respect to gender differences, women evidenced greater craving, stress and arousal ratings and lower valence ratings (greater negative emotion) in response to the negative affect/stressful script. While there were no gender differences in responses to smoking cues, women trended towards higher arousal ratings. Implications of the findings for treatment and tobacco-related morbidity and mortality are discussed.

    When a thin structure in which negative refraction occurs (a metallo-dielectric or a photonic crystal) is illuminated by a beam, the reflected and transmitted beam can undergo a large negative lateral shift. This phenomenon can be seen as an interferential enhancement of the geometrical shift and can be considered as a signature of negative refraction.

    2014-01-01

    SUMMARY The definition of the heterogeneous group of coagulase-negative staphylococci (CoNS) is still based on diagnostic procedures that fulfill the clinical need to differentiate between Staphylococcus aureus and those staphylococci classified historically as being less or nonpathogenic. Due to patient- and procedure-related changes, CoNS now represent one of the major nosocomial pathogens, with S. epidermidis and S. haemolyticus being the most significant species. They account substantially for foreign body-related infections and infections in preterm newborns. While S. saprophyticus has been associated with acute urethritis, S. lugdunensis has a unique status, in some aspects resembling S. aureus in causing infectious endocarditis. In addition to CoNS found as food-associated saprophytes, many other CoNS species colonize the skin and mucous membranes of humans and animals and are less frequently involved in clinically manifested infections. This blurred gradation in terms of pathogenicity is reflected by species- and strain-specific virulence factors and the development of different host-defending strategies. Clearly, CoNS possess fewer virulence properties than S. aureus, with a respectively different disease spectrum. In this regard, host susceptibility is much more important. Therapeutically, CoNS are challenging due to the large proportion of methicillin-resistant strains and increasing numbers of isolates with less susceptibility to glycopeptides. PMID:25278577

    Abstract Rationale: Plasmablastic lymphoma (PBL) is a rare subtype of human immunodeficiency virus (HIV)-related non-Hodgkin's lymphoma that predominantly manifests in the oral cavity. Patient concerns: Three cases of HIV-negative PBL were reported. Diagnoses: HIV-negative PBL Interventions: The patient had undergone chemotherapy. Outcomes: Clinical outcomes were very poor in Cases 1 and 3; Case 2, whose diagnosis suggested no bone marrow involvement, is still alive. Lessons subsections: These cases served to broaden the reported clinical spectrum of HIV-negative PBL. Clinicians and pathologists need to be familiar with lymphoma in the identified extra-oral PBL variation and there levant differential diagnosis procedures for this particular disease. PMID:28207555

    With dyadic data from a US Internet sample of 275 HIV-negative and 58 discordant male couples, we assessed HIV-negative partnered men's attitudes toward using an in-home rapid HIV test (HT) to screen potential new sex partners and associated factors by multivariate multilevel modeling. HIV-negative partnered men were "likely" to use an HT for screening purposes. More positive attitudes were associated with being in a mixed/nonwhite relationship; having an open sexual agreement. Less positive attitudes were associated with both partners being well educated. These findings may highlight how to make the most of HTs as risk-reduction screening tool among at-risk male couples.

    The experimental study on negative capacitance(NC) of various light-emitting diodes(LEDs) is presented.Experimental result shows that all LEDs display the NC phenomenon.The voltage modulated electroluminescence(VMEL) experiment confirms that the reason of negative capacitance is the strong recombination of the injected carriers in the active region of luminescence.The measures also verify that the dependence of NC on voltage and frequency in different LEDs is similar: NC phenomenon is more obvious with higher voltage or lower frequency.

    Full Text Available Introduction. Gossypiboma (GP is a term used to express the mass resulting from forgotten cotton sponge in operations. Rarely, a transmural migration may occur into the gastrointestinal lumen without creating any defect by GP. Laparotomy or endoscopic removal may be required, by the way it can be taken out of the body itself by intestinal ways. In this study, we reported a case of mechanical intestinal obstruction causing GP. Case. The fifty-one-year-old female patient admitted to the emergency department with the complaints of mechanical intestinal obstruction and had a history of open cholecystectomy 20 years ago. There were the findings of intestinal obstruction in abdominal plain radiography and computerized tomography. The sponge that obstructed the lumen completely 40 cm proximal to the ileocecal valve was identified in the laparotomy with the diagnosis of brid ileus. The small intestine was closed over double-fold after removal of sponge. Transmural migration of abdominal-remained sponge was thought to be occurred without creating a defect after cholecystectomy. Postoperatively, the patient was discharged without having any problems at 4th day of hospitalization. Conclusion. Although it is a rare situation in routine clinical practice, GP should be considered as a differential diagnosis in the patients who had a diagnosis of mechanical intestinal obstruction, and laparotomy was applied before. As GP may lead to situations which cause mortality, all precautions should be taken to prevent it.

    To address the need for novel alternatives to antibiotics, we attempted to sensitize gram-negative bacilli to innate antibacterial protagonists. We report a lipopeptide-like sequence (C10OOc12O) that inflicted outer membrane damage at a low micromolar range, whereas measurable bacterial growth inhibition in broth medium required >10-fold higher concentrations. In serum, however, C10OOc12O induced antibacterial activity in a manner suppressible by anticomplement antibodies or heat treatment and acted synergistically with exogenous lysozyme in broth and serum media. Upon subcutaneous administration, C10OOc12O exhibited high circulating levels that correlated with significant therapeutic efficacies, using either the mouse peritonitis-sepsis model or the thigh infection model. These findings are consistent with the view that, by damaging the outer membrane, C10OOc12O was able to enhance gram-negative bacilli susceptibility to antibacterial components of the immune humoral arm. Such lipopeptides may therefore be useful in fighting gram-negative bacilli threats through sensitization to endogenous and/or exogenous antibacterial proteins such as lysozyme and complements. © The Author 2017.

    Neoadjuvant chemotherapy (NAC) is the standard of care for locally advanced triple negative breast cancer, however, approximately 5% of cases show disease progression during NAC. Although downstaging is essential to create an opportunity for curative surgery and to improve the local control outcome in such a case, no additional line of chemotherapy has been established. A 60-year-old woman was referred to our hospital for an axillary mass presenting three weeks ago and was diagnosed as having right locally advanced (T2N2M0, stage IIIA) triple negative breast cancer. After two courses of epirubicine and cyclophosphamide as NAC, disease progression was recognized and curative resection was considered impossible due to enlarged axillary lymph nodes showing invasion to surrounding tissue. As second-line chemotherapy, weekly paclitaxel with bevacizumab treatment was initiated and significant shrinkage was immediately obtained. A clinically complete response was diagnosed after four courses of weekly paclitaxel with bevacizumab and she underwent a right breast mastectomy with axillary lymph node dissection without major complications. Histopathological examination of surgical specimens showed no residual invasive or noninvasive disease and she was diagnosed as having a pathological complete response. Although the addition of bevacizumab to standard adjuvant chemotherapy is not recommended in unselected triple negative breast cancer, the potent effect on tumor shrinkage should be considered in the treatment of locally advanced triple negative breast cancer showing disease progression during standard NAC.

    The stability of spontaneous electrical polarization in ferroelectrics is fundamental to many of their current applications, which range from the simple electric cigarette lighter to non-volatile random access memories. Research on nanoscale ferroelectrics reveals that their behaviour is profoundly different from that in bulk ferroelectrics, which could lead to new phenomena with potential for future devices. As ferroelectrics become thinner, maintaining a stable polarization becomes increasingly challenging. On the other hand, intentionally destabilizing this polarization can cause the effective electric permittivity of a ferroelectric to become negative, enabling it to behave as a negative capacitance when integrated in a heterostructure. Negative capacitance has been proposed as a way of overcoming fundamental limitations on the power consumption of field-effect transistors. However, experimental demonstrations of this phenomenon remain contentious. The prevalent interpretations based on homogeneous polarization models are difficult to reconcile with the expected strong tendency for domain formation, but the effect of domains on negative capacitance has received little attention. Here we report negative capacitance in a model system of multidomain ferroelectric-dielectric superlattices across a wide range of temperatures, in both the ferroelectric and paraelectric phases. Using a phenomenological model, we show that domain-wall motion not only gives rise to negative permittivity, but can also enhance, rather than limit, its temperature range. Our first-principles-based atomistic simulations provide detailed microscopic insight into the origin of this phenomenon, identifying the dominant contribution of near-interface layers and paving the way for its future exploitation.

    The structure of negative ions in liquid 4He is analyzed. The possibility of cluster or bubble formation around impurity ions of both signs is discussed. It is shown that in superfluid helium, bubbles form around negative alkaline earth metal ions and clusters form around halogen ions. The nature of "fast" and "exotic" negative ions is also discussed. It is assumed that "fast" ions are negative ions of helium excimer molecules localized inside bubbles. "Exotic" ions are stable negative impurity ions, which are always present in small amounts in gas discharge plasmas. Bubbles or clusters with radii smaller the radius of electron bubbles develop around these ions.

    Objective To discuss the pattern and effect of reading report activities on college-to-undergraduate nursing students in adult higher education. Methods We chose 154 college-to-undergraduate nursing students in adult higher education who studied at our department from 2009 to 2012 as control group, meanwhile the experimental group consisted of 168 college-to-undergrad-uate nursing students in adult higher education who studied at our department from 2013 to 2014.We used the"five-in-one"teaching method involving relevant scientific knowledge training, tutorial system, group report meeting, exchange of excellent reading report and score checking to train the experimental group, while the control group was still trained by primary method which was relevant scientific knowledge teaching and discussion of excellent reading report. Results The reading reports wrote by the students in the experimental group were superior to those wrote by the control group (P<0.001);The experimental group had better scores in the achievements of scientific knowledge and theory (P<0.001); The self-assessment of experimental group students in the ability of literature review, reading and analysis was higher than that of the control group (P<0.001).As to the effects of reading report such as enhancing scien-tific awareness, expanding scope of knowledge and so on, the experimental group had a obvious advantage over the control group ( P<0.001). Conclusion The "five-in-one"training pattern in the reading report activities involving relevant scientific knowledge training, tutorial system, group report meeting, exchange of excellent reading report and score checking can effectively improve the scientif-ic awareness of college-to-undergraduate nursing students in adult higher education, which is conductive to establish the basis of nurs-ing scientific research, guide the clinical nursing work and improve the comprehensive quality of students.%目的:提升护理学生的科研意识和能力

  18. WHEN ONE MIGHT EXPECT NEGATIVE DISCOUNT RATE?

    Directory of Open Access Journals (Sweden)

    Marcin Palenik

    2012-12-01

    Full Text Available Both in economics and psychology, positive discount rate is usually assumed as an axiom. However, there are circumstances which may lead to negative discount rate. This article presents such a phenomenon. Moreover, author presents particular cases of theories and models which imply preference of receiving lower income in later period of time, rather than higher income in earlier period of time (“less later than more earlier”. The described models are as follows: Life Cycle Hypothesis together with Self Control Theory, Construal Level Theory, Model of Patience Formation and Loewenstein’s Anticipation Model. Authors conclude that there is a need of empirical research verifying implications of these models concerning negative discount rate. Authors believe that the problem of negative discount rate deserves more attention, taking into account that in developed countries interest rates are close to zero and it still does not discourage customers from putting money aside.

Methods. HIV-negative Zimbabwean women (n=2,185 participating in a prospective study on hormonal contraception and HIV risk completed an ancillary questionnaire capturing detailed VP data at quarterly followup visits for two years. Results. Most participants (84% reported ever cleansing inside the vagina, and at 40% of visits women reported drying the vagina using cloth or paper. Vaginal tightening using cloth/cotton wool, lemon juice, traditional herbs/powders, or other products was reported at 4% of visits. Women with ≥15 unprotected sex acts monthly had higher odds of cleansing (adjusted odds ratio (aOR: 1.17, 95% CI: 1.04–1.32. Women with sexually transmitted infections had higher odds of tightening (aOR: 1.42, 95% CI: 1.08–1.86. Conclusion. Because certain vaginal practices were associated with other HIV risk factors, synergism between VPs and other risk factors should be explored.

Women with sexually transmitted infections had higher odds of tightening (aOR: 1.42, 95% CI: 1.08–1.86). Conclusion. Because certain vaginal practices were associated with other HIV risk factors, synergism between VPs and other risk factors should be explored. PMID:20871844

  1. The negation bias: when negations signal stereotypic expectancies.

    Research on linguistic biases shows that stereotypic expectancies are implicitly reflected in language and are thereby subtly communicated to message recipients. We examined whether these findings extend to the use of negations (e.g., not smart instead of stupid). We hypothesized that people use more negations in descriptions of stereotype-inconsistent behavior than in descriptions of stereotype-consistent behavior. In 3 studies, participants either judged the applicability of experimentally controlled person descriptions or spontaneously produced person descriptions themselves. Results provided support for this hypothesis. Moreover, a 4th study demonstrated that negations have communicative consequences. When a target person's behavior was described with negations, message recipients inferred that this behavior was an exception to the rule and that it was more likely caused by situational circumstances than by dispositional factors. These findings indicate that by using negations people implicitly communicate stereotypic expectancies and that negations play a subtle but powerful role in stereotype maintenance.

    Full Text Available Analysis of sentinel lymph nodes (SLNs by means of One-Step Nucleic Acid Amplification (OSNA is gaining widespread use as a quick and accurate method. This assay detects the expression level of cytokeratin 19 (CK19 which is present in some but not all breast tumors. In this study, the clinical significance of negative CK19 was investigated in 219 cases of primary breast cancer. In 179 patients with clinically negative nodes, OSNA and imprint smear cytology of SLN were performed simultaneously. The OSNA revealed a node-positive rate of 24.6%. Negative CK19 correlated significantly with negative ER/PgR and higher Ki-67 values, and marginally with higher nuclear grade and p53 overexpression. The triple negative subtype showed lower CK19 expression. OSNA revealed that one of the negative CK19 cases was actually a false negative but this was corrected with the use of the imprint smear cytology. In conclusion, CK19 negativity reflected the aggressiveness of primary breast cancer. OSNA assay used to analyze SLN was useful, but there is a possibility that it will mistakenly detect false negatives in CK19 negative tumors. Therefore, in tumors with negative CK19, the imprint smear cytology may be more useful in cases with macrometastasis.

    2016-07-01

    This study examines the relationship between negative experiences, negative emotions, and delinquent behavior among young people in a social withdrawal situation. There were 533 participants in this study and various quantitative analyses were utilized. Results showed that participants with a longer period of social withdrawal were generally less affected by negative experiences, while those with a higher level of social withdrawal were more affected by negative experiences, particularly negative relationships with other people. Also, both negative emotions and higher level of social withdrawal mediated the relationship between negative experiences and involvement in delinquent behavior, with negative emotions displaying a higher mediating effect. This reflects that the root of delinquent behavior is the negative experiences which arouse negative emotions, rather than the social withdrawal behavior itself. Results imply that practitioners should first explore the negative experiences suffered by these young people, so as to provide them the most appropriate support.

    The signature of the negative snakes from the soft X-ray cameras is very similar to the more usual snakes except that the localised region of the snake has, compared with its surroundings, decreased rather than increased emission. Circumstances where negative snakes have been seen are reviewed. The negative snake appears as a region of increased resistance and of increased impurity density. The relationship between the shear and the current perturbation is shown, and it seem probable that the magnetic shear is reversed at the point of the negative snake, i.e. that q is decreasing with radius. 6 refs., 6 figs.

  6. Compound negative binomial distribution with negative multinomial summands

    2016-12-01

    The class of Negative Binomial distributions seems to be introduced by Greenwood and Yule in 1920. Due to its wide spread application, investigations of distributions, closely related with it will be always contemporary. Bates, Neyman and Wishart introduce Negative Multinomial distribution. They reach it considering the mixture of independent Poisson distributed random variables with one and the same Gamma mixing variable. This paper investigates a particular case of multivariate compound distribution with one and the same compounding variable. In our case it is Negative Binomial or Sifted Negative Binomial. The summands with equal indexes in different coordinates are Negative Multinomially distributed. In case without shifting, considered as a mixture, the resulting distribution coincides with Mixed Negative Multinomial distribution with scale changed Negative Binomially distributed first parameter. We prove prove that it is Multivariate Power Series Distributed and find explicit form of its parameters. When the summands are geometrically distributed this distribution is stochastically equivalent to a product of independent Bernoulli random variable and appropriate multivariate Geometrically distributed random vector. We show that Compound Shifted Negative Binomial Distribution with Geometric Summands is a particular case of Negative Multinomial distribution with new parameters.

    Full Text Available Abstract Background HIV-negative, CD20-negative de novo diffuse large B-cell lymphoma (DLBCL patients has rarely been reported. To elucidate the nature of this entity, we retrospectively reviewed the data of 1,456 consecutive de novo DLBCL patients who were treated at Sun Yat-Sen University Cancer Center between January 1999 and March 2011. Methods The pathologic characteristics of CD20-negative patients, clinical features, response to initial treatment, and outcomes of 28 patients with available clinical data (n = 21 were reviewed. Then, a matched case-control (1:3 analysis was performed to compare patients with CD20-negative and -positive DLBCL. Results The median age of the 28 CD20-negative DLBCL patients was 48 years, with a male-female ratio of 20:8. Seventeen of 22 (77.3% CD20-negative DLBCL cases were of the non-germinal centre B-cell (non-GCB subtype. High Ki67 expression (≥80%, an index of cell proliferation, was demonstrated in 17 of 24 (70.8% cases. Extranodal involvement (≥ 1 site was observed in 76.2% of the patients. Following initial therapy, 9 of 21 (42.9% cases achieved complete remission, 4 (19% achieved partial remission, 1 (4.8% had stable disease, and 7 (33.3% had disease progression. The median overall survival was 23 months. The 3-year progression-free survival (PFS and overall survival (OS rates were 30.5% and 35%, respectively. A matched case-control analysis showed that patients with CD20-negative and -positive DLBCL did not exhibit a statistically significant difference with respect to the main clinical characteristics (except extranodal involvement, whereas the patients with CD20-positive DLBCL had a better survival outcome with 3-year PFS (P = 0.008 and OS (P = 0.008 rates of 52% and 74.1%, respectively. Conclusions This study suggests that HIV-negative, CD20-negative de novo DLBCL patients have a higher proportion of non-GCB subtype, a higher proliferation index, more frequent extranodal involvement, a poorer

    2014-08-27

    In inkless microcontact printing (IμCP) by soft lithography, the poly(dimethylsiloxane) (PDMS) stamp transfers uncured polymer to a substrate corresponding to its pattern. The spontaneous diffusion of PDMS oligomers to the surface of the stamp that gives rise to this deleterious side effect has been leveraged to fabricate a variety of devices, such as organic thin film transistors, single-electron devices, and biomolecular chips. Here we report an anomalous observation on a partially cured PDMS stamp where the transfer of oligomers onto Au occurred on regions that were not in contact with the stamp, while the surface in contact with the stamp was pristine with no polymer. On the SiO2 surface of the same chip, as expected, the transfer of PDMS occurred exclusively on regions in contact with the stamp. The printing on Au was quantified by a novel method where the submonolayer of PDMS transfer was measured by probing the local electrochemical passivation of the Au. The local transfer of polymer on SiO2 (and also Au) was measured by selective deposition of Au nanoparticle necklaces that exclusively deposited on PDMS at submonolayer sensitivity. It was discovered that the selectivity and sharpness of PDMS deposition on Au for inkless printing (i.e., negative) is significantly better than the traditional (positive) microcontact printing where the stamp is "inked" with low molecular weight PDMS.

    2010-07-01

    This study examined the effects of negative aging stereotypes on self-reported loneliness, risk-taking, subjective health, and help-seeking behavior in a French sample of older adults. The aim of this study was to show the detrimental effects of negative aging stereotypes on older adults' self-evaluations and behaviors, therefore contributing to the explanations of the iatrogenic effect of social environments that increase dependency (e.g., health care institutions). In the first experiment conducted on 57 older adults, we explored the effects of positive, neutral, or negative stereotype activation on the feeling of loneliness and risk taking decision. The second experiment (n = 60) examined the impact of stereotype activation on subjective health, self-reported extraversion as well as on a genuine help-seeking behavior, by allowing participants to ask for the experimenter's help while completing a task. As predicted, negative stereotype activation resulted in lower levels of risk taking, subjective health and extraversion, and in higher feelings of loneliness and a more frequent help-seeking behavior. These findings suggest that the mere activation of negative stereotypes can have broad and deleterious effects on older individuals' self-evaluation and functioning, which in turn may contribute to the often observed dependency among older people.

    The importance of spatial nonlocality in the description of negative refraction in electromagnetic materials has been put forward recently. We develop a theory of negative refraction in homogeneous and isotropic media, based on first principles, and that includes nonlocality in its full generality. The theory shows that both dissipation and spatial nonlocality are necessary conditions for the existence of negative refraction. It also provides a sufficient condition in materials with weak spatial nonlocality. These fundamental results should have broad implications in the theoretical and practical analyses of negative refraction of electromagnetic and other kinds of waves.

    Studies investigating neurobiological bases of negative symptoms of schizophrenia failed to provide consistent findings, possibly due to the heterogeneity of this psychopathological construct. We tried to review the findings published to date investigating neurobiological abnormalities after reducing the heterogeneity of the negative symptoms construct. The literature in electronic databases as well as citations and major articles are reviewed with respect to the phenomenology, pathology, genetics and neurobiology of schizophrenia. We searched PubMed with the keywords "negative symptoms," "deficit schizophrenia," "persistent negative symptoms," "neurotransmissions," "neuroimaging" and "genetic." Additional articles were identified by manually checking the reference lists of the relevant publications. Publications in English were considered, and unpublished studies, conference abstracts and poster presentations were not included. Structural and functional imaging studies addressed the issue of neurobiological background of negative symptoms from several perspectives (considering them as a unitary construct, focusing on primary and/or persistent negative symptoms and, more recently, clustering them into factors), but produced discrepant findings. The examined studies provided evidence suggesting that even primary and persistent negative symptoms include different psychopathological constructs, probably reflecting the dysfunction of different neurobiological substrates. Furthermore, they suggest that complex alterations in multiple neurotransmitter systems and genetic variants might influence the expression of negative symptoms in schizophrenia. On the whole, the reviewed findings, representing the distillation of a large body of disparate data, suggest that further deconstruction of negative symptomatology into more elementary components is needed to gain insight into underlying neurobiological mechanisms.

    Participants performed a physical comparison task of pairs of positive and pairs of negative one-digit numbers while their electrophysiological brain activity was measured. The numerical value of the presented digits was either congruent or incongruent with the physical size of the digits. Analysis has shown that the earliest event-related potential (ERP) difference between positive and negative numbers was found in the P300 ERP component peak, where there was an inverse effect of congruity in the negative pairs, compared with the positive ones. This pattern of results supports the idea that natural numbers serve as primitives of the human cognitive system, whereas negative numbers are apparently generated if needed.

    Many theoretical accounts of selective attention and memory retrieval include reference to active inhibitory processes, such as those argued to underlie the negative priming effect. fMRI was used in order to investigate the areas of cortical activation associated with Stroop interference, Stroop facilitation and Stroop negative priming tasks. The most significant activation within the negative priming task was within the inferior parietal lobule, left temporal lobe and frontal lobes. Areas of cortical activation are discussed with reference to theoretical accounts of the negative priming effect.

  4. Higher prices in Jamaica.

    1982-03-01

    Price increases in the Jamaica CSM program went into effect on August 31, 1981. The program began in 1975. While the need for higher prices has been under discussion for the past 3 years, this is the 1st time the requisite approval from the Jamaica Price Commission has been obtained. The Jamaica National Family Planning Board (JNFPB) reports that the Panther 3-pack (condom) is up US$0.15 to US$0.30. Each Perle package (oral contraceptive) was increased by US$0.20. Single cycle Perle now sells for US$0.50, and 3-pack Perle sells for US$1.10. The 6-year price stagnation experienced by the CSM program resulted in a decreasing operational budget as program costs continued to rise. Marketing costs alone during this period escalated by 100-300%. For example, Panther pop-up display cartons cost the project US 16U each in 1975. By 1979 the same product cost US 49U. Newspaper advertisements have increased from the 1975 cost of US$68.00 to nearly $200.00 per placement. The overall inflation rate in Jamaica during the last 5 years has averaged more than 20% annually. In the face of these rising costs, outlet expansion for Perle has been prevented, wholesaler margins have been unavailable, and new retailer training has been discontinued. It is projected that the new prices will result in an annual increased revenues of US$80,000 which will be used to reinstate these essential marketing activities. The JNFPB is also planning to introduce a Panther 12-pack and Panther strips to the CSM product line. According to Marketing Manager Aston Evans, "We believe the public is now ready for this type of packaging" which is scheduled to be available soon. Panther is presently only available in a 3-pack, but annual sales have been steady. The new 12-pack will be stocked on supermarket shelves to provide higher product visibility and wider distribution. The selling price has been set as US$1.20 and is expected to yield a 25% increase in sales during the 1st year. A complete sales promotion

    Full Text Available The paper represents the first report of negative superposition in our country. Photo of randomly selected young, living woman was superimposed on the previously discovered female skull. Computer program Adobe Photoshop 7.0 was used in work. Digitilized photographs of the skull and face, after uploaded to computer, were superimposed on each other and displayed on the monitor in order to assess their possible similarities or differences. Special attention was payed to matching the same anthropometrical points of the skull and face, as well as following their contours. The process of fitting the skull and the photograph is usually started by setting eyes in correct position relative to the orbits. In this case, lower jaw gonions go beyond the face contour and gnathion is highly placed. By positioning the chin, mouth and nose their correct anatomical position cannot be achieved. All the difficulties associated with the superposition were recorded, with special emphasis on critical evaluation of work results in a negative superposition. Negative superposition has greater probative value (exclusion of identification than positive (possible identification. 100% negative superposition is easily achieved, but 100% positive - almost never. 'Each skull is unique and viewed from different perspectives is always a new challenge'. From this point of view, identification can be negative or of high probability.

  6. The Negative Affect Hypothesis of Noise Sensitivity

    Directory of Open Access Journals (Sweden)

    Daniel Shepherd

    2015-05-01

    Full Text Available Some studies indicate that noise sensitivity is explained by negative affect, a dispositional tendency to negatively evaluate situations and the self. Individuals high in such traits may report a greater sensitivity to other sensory stimuli, such as smell, bright light and pain. However, research investigating the relationship between noise sensitivity and sensitivity to stimuli associated with other sensory modalities has not always supported the notion of a common underlying trait, such as negative affect, driving them. Additionally, other explanations of noise sensitivity based on cognitive processes have existed in the clinical literature for over 50 years. Here, we report on secondary analyses of pre-existing laboratory (n = 74 and epidemiological (n = 1005 data focusing on the relationship between noise sensitivity to and annoyance with a variety of olfactory-related stimuli. In the first study a correlational design examined the relationships between noise sensitivity, noise annoyance, and perceptual ratings of 16 odors. The second study sought differences between mean noise and air pollution annoyance scores across noise sensitivity categories. Results from both analyses failed to support the notion that, by itself, negative affectivity explains sensitivity to noise.

    Abraham, Eitan; Penrose, Oliver

    2017-01-01

    Negative absolute temperatures were introduced into experimental physics by Purcell and Pound, who successfully applied this concept to nuclear spins; nevertheless, the concept has proved controversial: a recent article aroused considerable interest by its claim, based on a classical entropy formula (the "volume entropy") due to Gibbs, that negative temperatures violated basic principles of statistical thermodynamics. Here we give a thermodynamic analysis that confirms the negative-temperature interpretation of the Purcell-Pound experiments. We also examine the principal arguments that have been advanced against the negative temperature concept; we find that these arguments are not logically compelling, and moreover that the underlying "volume" entropy formula leads to predictions inconsistent with existing experimental results on nuclear spins. We conclude that, despite the counterarguments, negative absolute temperatures make good theoretical sense and did occur in the experiments designed to produce them.

    2003-01-01

    This paper describes negative correlation learning for designing neural network ensembles. Negative correlation learning has been firstly analysed in terms of minimising mutual information on a regression task. By ninimising the mutual information between variables extracted by two neural networks, they are forced to convey different information about some features of their input. Based on the decision boundaries and correct response sets, negative correlation learning has been further studied on two pattern classification problems. The purpose of examining the decision boundaries and the correct response sets is not only to illustrate the learning behavior of negative correlation learning, but also to cast light on how to design more effective neural network ensembles. The experimental results showed the decision boundary of the trained neural network ensemble by negative correlation learning is almost as good as the optimum decision boundary.

    With the recent resurgence of interest in double negative (DNG) materials and the reported construction of a metamaterial with DNG characteristics, applications of these materials become feasible and examination of the behavior of systems and devices a potentially fruitful topic. The most promising area of research, upon inquiry into past work related to DNG materials, proves to be dielectric waveguides. The present investigation, then, focuses on the inclusion of DNG materials in various ...

  15. Eating behaviors and negative affect in college women's everyday lives.

    A growing body of research seeks to understand the relationship between mood and eating behaviors. Ecological Momentary Assessment (EMA) methods provide a method for assessing these processes in natural settings. We used EMA to examine the relationship between mood and eating behaviors in everyday life among women with subclinical disordered eating behaviors. Participants (N = 127, age M = 19.6 years, BMI M = 25.5) completed five daily EMA reports on palmtop computers for 1 week. Assessments included measures of negative affect (NA) and eating-related behavior during eating (eating large amounts of food, loss of control over eating, and restricting food intake) and noneating episodes (skip eating to control weight/shape). Time-lagged multilevel models tested mood-eating behavior relationships. Higher NA did not precede any unhealthy eating and weight control behaviors. However, NA was higher when women reported eating large quantities of food, losing control over eating, and restricting food intake during their most recent eating episode, but not after skipping eating to control weight/shape. These findings elucidate the processes in daily life that may influence the development and maintenance of unhealthy eating and weight control behaviors that, in turn, can inform interventions. © 2014 Wiley Periodicals, Inc.

    1995-08-01

    The social problem-solving skill of generating effective alternative solutions was tested as a moderator of the relation between negative life stress and depressed mood in children. Boys (n = 25) and girls (n = 25), ages 8 to 12 years, from inner-city, lower socioeconomic group families, completed measures of depression symptoms, negative impact of life events, and quantity and effectiveness of alternative solutions to social problems. Results indicated that the effectiveness of alternative solutions children generate in response to peer social problems moderates the relation between stress and depression. Children who experienced a high impact of negative life events, with less effective social problem-solving skills, reported higher levels of depression compared to children who experienced a high impact of negative life events but exhibited more effective social problem-solving skills. Results are discussed in terms of alternative theoretical models for the mechanisms whereby effective social problem-solving skills moderate stress-related depression.

    Negative refraction is such a prominent electromagnetic phenomenon that most researchers believe it can only occur in artificially engineered metamaterials. In this article, we report negative refraction for all incident angles for the first time in a naturally existing material. Using ellipsometry measurement of the equifrequency contour in the deep-ultraviolet frequency region (typically 254 nm), obvious negative refraction was demonstrated in monocrystalline graphite for incident angles ra...

    Higher category theory is generally regarded as technical and forbidding, but part of it is considerably more tractable: the theory of infinity-categories, higher categories in which all higher morphisms are assumed to be invertible. In Higher Topos Theory, Jacob Lurie presents the foundations of this theory, using the language of weak Kan complexes introduced by Boardman and Vogt, and shows how existing theorems in algebraic topology can be reformulated and generalized in the theory's new language. The result is a powerful theory with applications in many areas of mathematics. The book's firs

    LENUS (Irish Health Repository)

    Daly, A

    2016-05-01

    Traditionally, the modified Duke\\'s criteria, based primarily on positive blood cultures, is used to diagnose Infective Endocarditis (IE). However, reports demonstrate that 31% of cases are diagnosed as Culture Negative Infective Endocarditis (CNIE)1. Consequently, empiric broad-spectrum antibiotics are prescribed to cover unidentified organisms and, as a result, antibiotic therapy may be compromised. Molecular diagnostic techniques aid with identifying causative organisms in cases of CNIE and we question if the increasing use of such technologies will change the local epidemiology of CNIE. We present the first case of Tropheryma whipplei Infective Endocarditis (TWIE) reported in Ireland.

  2. Isotropic Negative Thermal Expansion Metamaterials.

    2016-07-13

    Negative thermal expansion materials are important and desirable in science and engineering applications. However, natural materials with isotropic negative thermal expansion are rare and usually unsatisfied in performance. Here, we propose a novel method to achieve two- and three-dimensional negative thermal expansion metamaterials via antichiral structures. The two-dimensional metamaterial is constructed with unit cells that combine bimaterial strips and antichiral structures, while the three-dimensional metamaterial is fabricated by a multimaterial 3D printing process. Both experimental and simulation results display isotropic negative thermal expansion property of the samples. The effective coefficient of negative thermal expansion of the proposed models is demonstrated to be dependent on the difference between the thermal expansion coefficient of the component materials, as well as on the circular node radius and the ligament length in the antichiral structures. The measured value of the linear negative thermal expansion coefficient of the three-dimensional sample is among the largest achieved in experiments to date. Our findings provide an easy and practical approach to obtaining materials with tunable negative thermal expansion on any scale.

    Most solids expand when they are heated, but a property known as negative thermal expansion has been observed in a number of materials, including the oxide ZrW2O8 (ref. 1) and the framework material ZnxCd1-x(CN)2 (refs 2,3). This unusual behaviour can be understood in terms of low-energy phonons, while the colossal values of both positive and negative thermal expansion recently observed in another framework material, Ag3[Co(CN)6], have been explained in terms of the geometric flexibility of its metal-cyanide-metal linkages. Thermal expansion can also be stopped in some magnetic transition metal alloys below their magnetic ordering temperature, a phenomenon known as the Invar effect, and the possibility of exploiting materials with tuneable positive or negative thermal expansion in industrial applications has led to intense interest in both the Invar effect and negative thermal expansion. Here we report the results of thermal expansion experiments on three magnetic nanocrystals-CuO, MnF2 and NiO-and find evidence for negative thermal expansion in both CuO and MnF2 below their magnetic ordering temperatures, but not in NiO. Larger particles of CuO and MnF2 also show prominent magnetostriction (that is, they change shape in response to an applied magnetic field), which results in significantly reduced thermal expansion below their magnetic ordering temperatures; this behaviour is not observed in NiO. We propose that the negative thermal expansion effect in CuO (which is four times larger than that observed in ZrW2O8) and MnF2 is a general property of nanoparticles in which there is strong coupling between magnetism and the crystal lattice.

  5. Physical effects of negative air ions in a wet sauna

    Watanabe, I.; Noro, Hiroshi; Ohtsuka, Yoshinori; Mano, Yukio; Agishi, Yuko

    The physical effects of negative air ions on humans were determined in an experimental sauna room equipped with an ionizer. Thirteen healthy persons took a wet sauna bath (dry bulb temperature 42° C, relative humidity 100%, 10 min exposure) with or without negative air ions. The subjects were not told when they were being exposed to negative air ions. There were no differences in the moods of these persons or changes in their blood pressures between the two saunas. The surface temperatures of the foreheads, hands, and legs in the sauna with negative ions were significantly higher than those in the sauna without ions. The pulse rates and sweat produced in the sauna with ions were singificantly higher than those in the sauna without ions. The results suggest that negative ions may amplify the effects on humans of the sauna.

    Full Text Available We report the case of a 49-year-old male with clinical and histological findings consistent with hypertrophic lupus erythematosus (HLE. HLE must be clinically and histologically differentiated from keratoacanthoma, hypertrophic lichen planus, squamous cell carcinoma and plaque type psoriasis. CD123 positivity and transepidermal elimination of elastin have recently been reported as tools to distinguish HLE. Interestingly, in this case, biopsies of two separate lesions failed to reveal these two features. The etiology of this discrepancy is unknown and further studies are needed to clarify the utility of CD123 positivity and transepidermal elimination of elastin in the diagnosis of hypertrophic lupus erythematosus.

  2. Expression of Androgen Receptor Is Negatively Regulated By p53

    Directory of Open Access Journals (Sweden)

    Fatouma Alimirah

    2007-12-01

    Full Text Available Increased expression of androgen receptor (AR in prostate cancer (PC is associated with transition to androgen independence. Because the progression of PC to advanced stages is often associated with the loss of p53 function, we tested whether the p53 could regulate the expression of AR gene. Here we report that p53 negatively regulates the expression of AR in prostate epithelial cells (PrECs. We found that in LNCaP human prostate cancer cells that express the wild-type p53 and AR and in human normal PrECs, the activation of p53 by genotoxic stress or by inhibition of p53 nuclear export downregulated the expression of AR. Furthermore, forced expression of p53 in LNCaP cells decreased the expression of AR. Conversely, knockdown of p53 expression in LNCaP cells increased the AR expression. Consistent with the negative regulation of AR expression by p53, the p53-null HCT116 cells expressed higher levels of AR compared with the isogenic HCT116 cells that express the wildtype p53. Moreover, we noted that in etoposide treated LNCaP cells p53 bound to the promoter region of the AR gene, which contains a potential p53 DNA-binding consensus sequence, in chromatin immunoprecipitation assays. Together, our observations provide support for the idea that the loss of p53 function in prostate cancer cells contributes to increased expression of AR.

    The goal of the current study was to examine the combined influence of positive reinforcement processes using a behavioral task measuring risk taking propensity (RTP) and negative reinforcement processes using a behavioral task measuring deficits in distress tolerance (DT) on a range of risk taking behaviors among early adolescents. Participants included a community sample of 230 early adolescents (aged 9-13) who completed two behavioral tasks assessing reinforcement processes as well as reported on past year risk behavior involvement as assessed by items from the Youth Risk Behavior Surveillance System at a baseline and a 1-year follow-up assessment. Data indicated that at the Wave 2 assessment, RTP was positively related to number of risk-taking behaviors in the past year but only for those with low DT, with this finding persisting after controlling for the significant influence of male gender and higher sensation seeking. Results of the present study highlight the importance of considering both positive and negative reinforcement processes in combination when investigating vulnerability factors for early risk behavior engagement in youth.

  4. Higher prices, higher quality? Evidence from German nursing homes.

    Science.gov (United States)

    Herr, Annika; Hottenrott, Hanna

    2016-02-01

    This study investigates the relationship between prices and quality of 7400 German nursing homes. We use a cross section of public quality reports for all German nursing homes, which had been evaluated between 2010 and 2013 by external institutions. Our analysis is based on multivariate regressions in a two stage least squares framework, where we instrument prices to explain their effect on quality controlling for income, nursing home density, demographics, labour market characteristics, and infrastructure at the regional level. Descriptive analysis shows that prices and quality do not only vary across nursing homes, but also across counties and federal states and that quality and prices correlate positively. Second, the econometric analysis, which accounts for the endogenous relation between negotiated price and reported quality, shows that quality indeed positively depends on prices. In addition, more places in nursing homes per people in need are correlated with both lower prices and higher quality. Finally, unobserved factors at the federal state level capture some of the variation of reported quality across nursing homes. Our results suggest that higher prices increase quality. Furthermore, since reported quality and prices vary substantially across federal states, we conclude that the quality and prices of long-term care facilities may well be compared within federal states but not across.

  6. Adjective metaphors evoke negative meanings.

    Science.gov (United States)

    Sakamoto, Maki; Utsumi, Akira

    2014-01-01

    Previous metaphor studies have paid much attention to nominal metaphors and predicative metaphors, but little attention has been given to adjective metaphors. Although some studies have focused on adjective metaphors, they only examined differences in the acceptability of various types of adjective metaphors. This paper explores the cognitive effects evoked by adjective metaphors. Three psychological experiments revealed that (1) adjective metaphors, especially those modified by color adjectives, tend to evoke negative effect; (2) although the meanings of metaphors are basically affected by the meanings of their vehicles, when a vehicle has a neutral meaning, negative meanings are evoked most frequently for adjective metaphors compared to nominal and predicative metaphors; (3) negative meanings evoked by adjective metaphors are related to poeticness, and poetic metaphors evoke negative meanings more easily than less poetic metaphors. Our research sheds new light on studies of the use of metaphor, which is one of the most basic human cognitive abilities.

    Das, Runa; LeFevre, Jo-Anne; Penner-Wilger, Marcie

    2010-10-01

    Are negative numbers processed differently from positive numbers in arithmetic problems? In two experiments, adults (N = 66) solved standard addition and subtraction problems such as 3 + 4 and 7 - 4 and recasted versions that included explicit negative signs-that is, 3 - (-4), 7 + (-4), and (-4) + 7. Solution times on the recasted problems were slower than those on standard problems, but the effect was much larger for addition than subtraction. The negative sign may prime subtraction in both kinds of recasted problem. Problem size effects were the same or smaller in recasted than in standard problems, suggesting that the recasted formats did not interfere with mental calculation. These results suggest that the underlying conceptual structure of the problem (i.e., addition vs. subtraction) is more important for solution processes than the presence of negative numbers.

    2016-07-01

    Enhancement of ferroelectric properties, both spontaneous polarization and Curie temperature under negative pressure had been predicted in the past from first principles and recently confirmed experimentally. In contrast, piezoelectric properties are expected to increase by positive pressure, through polarization rotation. Here we investigate the piezoelectric response of the classical PbTiO3, Pb(Zr,Ti)O3 and BaTiO3 perovskite ferroelectrics under negative pressure from first principles and find significant enhancement. Piezoelectric response is then tested experimentally on free-standing PbTiO3 and Pb(Zr,Ti)O3 nanowires under self-sustained negative pressure, confirming the theoretical prediction. Numerical simulations verify that negative pressure in nanowires is the origin of the enhanced electromechanical properties. The results may be useful in the development of highly performing piezoelectrics, including lead-free ones.

  10. The Implicit Positive and Negative Affect Test: Validity and Relationship with Cardiovascular Stress-Responses.

    van der Ploeg, Melanie M; Brosschot, Jos F; Thayer, Julian F; Verkuil, Bart

    2016-01-01

    Self-report, i.e., explicit, measures of affect cannot fully explain the cardiovascular (CV) responses to stressors. Measuring affect beyond self-report, i.e., using implicit measures, could add to our understanding of stress-related CV activity. The Implicit Positive and Negative Affect Test (IPANAT) was administered in two studies to test its ecological validity and relation with CV responses and self-report measures of affect. In Study 1 students (N = 34) viewed four film clips inducing anger, happiness, fear, or no emotion, and completed the IPANAT and the Positive And Negative Affect Scale at baseline and after each clip. Implicit negative affect (INA) was higher and implicit positive affect (IPA) was lower after the anger inducing clip and vice versa after the happiness inducing clip. In Study 2 students performed a stressful math task with (n = 14) or without anger harassment (n = 15) and completed the IPANAT and a Visual Analog Scale as an explicit measure afterwards. Systolic (SBP), diastolic (DBP) blood pressure, heart rate (HR), heart rate variability (HRV), and total peripheral resistance (TPR) were recorded throughout. SBP and DBP were higher and TPR was lower in the harassment condition during the task with a prolonged effect on SBP and DBP during recovery. As expected, explicit negative affect (ENA) was higher and explicit positive affect (EPA) lower after harassment, but ENA and EPA were not related to CV activity. Although neither INA nor IPA differed between the tasks, during both tasks higher INA was related to higher SBP, lower HRV and lower TPR and to slower recovery of DBP after both tasks. Low IPA was related to slower recovery of SBP and DBP after the tasks. Implicit affect was not related to recovery of HR, HRV, and TPR. In conclusion, the IPANAT seems to respond to film clip-induced negative and positive affect and was related to CV activity during and after stressful tasks. These findings support the theory that implicitly measured affect

  13. Negative effects of positive reinforcement

    2003-01-01

    Procedures classified as positive reinforcement are generally regarded as more desirable than those classified as aversive—those that involve negative reinforcement or punishment. This is a crude test of the desirability of a procedure to change or maintain behavior. The problems can be identified on the basis of theory, experimental analysis, and consideration of practical cases. Theoretically, the distinction between positive and negative reinforcement has proven difficult (some would say t...

    Photonic crystals are multidimensional periodic gratings, in which the light propagation is dominated by Bragg diffraction that appears to be refraction at the flat surfaces of the crystals. The refraction angle from positive to negative, perfectly or only partially obeying Snell’s law, can be tailored based on photonic band theory. Negative refraction enables novel prism, collimation, and lens effects. Because photonic crystals usually consist of two transparent media, these effects occur at...

  15. Negative attitudes toward masturbation in sex therapy.

    Science.gov (United States)

    Mosher, D L

    1979-01-01

    The incidence of masturbation in males and females as reported by Kinsey was cited as basic data to support Gagnon and Simon's theoretical conceptions of differences in the psychosexual development of males and females. The use of masturbation as treatment in sex therapy was reviewed. An inventory to measure negative attitudes toward masturbation was described, and four research studies supporting its construct validity was summarized. The affective-cognitive structure of masturbation-guilt was posited to inhibit masturbatory behavior and to elicit negative affects such as guilt and disgust as a consequence of masturbation. The use of the inventory measuring negative attitudes toward masturbation was illustrated using the P-LI-SS-IT model. Intensive therapy from a gestalt sex therapy perspective was illustrated as integrating the negative masturbatory schema into self-regulating awareness-expression cycles. A caution to sex therapists alerted them to the importance of awareness of emotions, fantasy, and sociosexual meanings in sex therapy rather than using masturbation as a packaged technique.

  16. Higher arithmetic Chow groups

    Gil, J I Burgos

    2009-01-01

    We give a new construction of higher arithmetic Chow groups for quasi-projective arithmetic varieties over a field. Our definition agrees with the higher arithmetic Chow groups defined by Goncharov for projective arithmetic varieties over a field. These groups are the analogue, in the Arakelov context, of the higher algebraic Chow groups defined by Bloch. The degree zero group agrees with the arithmetic Chow groups of Burgos. Our new construction is shown to be a contravariant functor and is endowed with a product structure, which is commutative and associative.

    In this paper we generalize the Koszul complexes and Koszul algebras, and introduce the higherKoszul (t-Koszul) complexes and higher Koszul algebras, where t ≥ 2 is an integer. We prove that an algebra ist-Koszul if and only if its t-Koszul complex is augmented, i.e. the higher degree (≥ 1) homologies vanish. Forarbitrary t-Koszul algebra , we also give a description of the structure of the cohomology algebra Ext ( 0, 0)by using the t-Koszul complexes, where the 0 is the direct sum of the simples.

    Different phenomena are observed under negative gate voltage stress which is smaller than the previous degradation stress in PMOSFETs with different oxide thicknesses. We adopt the real time method to make a point of the drain current to study the degradation and recovery of negative bias temperature instability (NBTI). For the device with thin oxide, recovery phenomenon appears when smaller negative voltage stress was applied, due to the more influencing oxide charges detrapping effects than the interface states. For the device with thick oxide, not recovery but degradation phenomenon comes forth. As many charges are trapped in the deeper position and higher energy level in the oxide, these charges can not be detrapped. Therefore, the effect of the charge detrapping is smaller than that of the interface states in the thick oxide. The degradation presents itself during the 'recovery' time.

    Bassetti, Matteo; Repetto, Ernestina

    2008-04-01

    Among Gram negative bacteria, Pseudomonas aeruginosa, the extended spectrum beta-lactamases (ESBL)-producing strains, Acinetobacter spp, in particular the multiresistant Acinetobacter baumannii, and Stenotrophomonas maltophilia are the most implicated micrororganisms in the ever more increasing problem of bacterial resistance. Possible solutions have to be searched, on one hand, in the use of new drugs but, on the other hand, in the re-evaluation of those already available drugs, possibly considering a new role for old drugs such as colistine and fosfomycin. Concerning ESBL-producing strains, the most recent data provided by EARSS report, in Italy, an incidence rate of 10-25 percent. The insurgence of an infection sustained by an ESBL+ve strain is strictly related to some well known risk factors, like the hospital stay itself, the disease severity, the length of stay in ICU, intubation and mechanical ventilation, catheterization, urinary or artery, and the past exposure to antibiotics. The raise in ESBL producing strains is closely related to the increasing use of cephalosporins. In the setting of a Gram negative infection, the combination therapy guarantees a higher coverage by reducing insurgence of possible resistance mechanisms, possibly resulting synergistic, and allowing a de-escalation therapy, although to this latter other problems, such as tolerability, costs and compliance, can be related. Another basic aspect to take into account of, in order to achieve the maximal efficacy of the antibiotic treatment, is the right dosage. In the idea to look for the best approach for the antibiotic treatment of a severe infection in a hospital setting, when a Gram negative aetiology is implicated, it can be possibly presumed that the right way consists in avoiding inappropriate antibiotic therapies, making therapeutic choices based on guidelines resulted from local epidemiological data, initiating the therapy promptly, avoiding excessive use of antibiotics, possibly

    Subjects were divided into high and low negative self-statement and high and low positive-self-statement groups on the basis of the assertiveness self-statement test (Schwartz & Gottman, 1976). High negative self-statement subjects reported more anxiety during assertion role plays than did low negative self-statement subjects and were rated by judges as exhibiting more non-verbal anxiety and performing less assertively than low negative self-statement subjects. Judges rated high positive self-statement subjects as more irritable and brusque than low positive self-statement subjects. Theoretical implications are discussed.

    Categorical learning is dependent on feedback. Here, we compare how positive and negative feedback affect information-integration (II) category learning. Ashby and O'Brien (2007) demonstrated that both positive and negative feedback are required to solve II category problems when feedback was not guaranteed on each trial, and reported no differences between positive-only and negative-only feedback in terms of their effectiveness. We followed up on these findings and conducted 3 experiments in which participants completed 2,400 II categorization trials across three days under 1 of 3 conditions: positive feedback only (PFB), negative feedback only (NFB), or both types of feedback (CP; control partial). An adaptive algorithm controlled the amount of feedback given to each group so that feedback was nearly equated. Using different feedback control procedures, Experiments 1 and 2 demonstrated that participants in the NFB and CP group were able to engage II learning strategies, whereas the PFB group was not. Additionally, the NFB group was able to achieve significantly higher accuracy than the PFB group by Day 3. Experiment 3 revealed that these differences remained even when we equated the information received on feedback trials. Thus, negative feedback appears significantly more effective for learning II category structures. This suggests that the human implicit learning system may be capable of learning in the absence of positive feedback.

    We employ a novel paradigm to test whether six basic emotions (sadness, fear, disgust, anger, surprise, and happiness; Ekman, 1992) contain both negativity and positivity, as opposed to consisting of a single continuum between negative and positive. We examined the perceived negativity and positivity of these emotions in terms of their affective and cognitive components among Korean, Chinese, Canadian, and American students. Assessing each emotion at the cognitive and affective levels cross-culturally provides a fairly comprehensive picture of the positivity and negativity of emotions. Affective components were rated as more divergent than cognitive components. Cross-culturally, Americans and Canadians gave higher valence ratings to the salient valence of each emotion, and lower ratings to the non-salient valence of an emotion, compared to Chinese and Koreans. The results suggest that emotions encompass both positivity and negativity, and there were cross-cultural differences in reported emotions. This paradigm complements existing emotion theories, building on past research and allowing for more parsimonious explanations of cross-cultural research on emotion.

    Full Text Available In sport, winning and losing are usually propounded as the most important criteria for the evaluation of coaches' competences. Thus, negative coaching behaviours are too often ignored, particularly if those behaviours are associated with sport success. Since existing measures for the assessment of coaches' leadership style are dominantly focused on positive aspects of coaching behaviours, the main aim of the study was to develop and validate the Negative Coaching Behaviour Questionnaire (NCBQ. An additional aim was to examine possible differences in perceptions of coaches' behaviour between athletes from individual versus team sports. The NCBQ is a 13-item inventory that assesses undesirable coach’s behaviour on three subscales, i.e. Insensitivity to Athletes’ Wellbeing, Negative Feedback, and Results Orientation. Psychometric characteristics of NCBQ (factor structure, reliability, sensitivity, convergent and divergent validity were tested on a sample of 181 kinesiology students. The results showed that NCBQ is valid and reliable measure useful for the assessment of negative coaching behaviours in various sport-related research. As expected, athletes from team sports reported a higher frequency of negative and a lower frequency of positive coaching behaviours. In future studies, more attention should be given to exploring antecedents, correlates and consequences of different coaching behaviours.

    Ninety-seven undergraduates, 48 of whom had a history of self-reported major depression, completed measures of mood and cognitive style (e.g. explanatory style, explanatory flexibility, dysfunctional attitudes) prior to and directly after a negative mood priming challenge that consisted of listening to sad music and thinking about an upsetting past event. Eighteen of the previously depressed participants endorsed baseline levels of depression, explanatory style for negative events, and dysfunctional attitudes higher than levels reported by never depressed participants or euthymic participants with a history of depression. All three groups (never depressed participants, dysphoric participants with a history of depression, euthymic participants with a history of depression) demonstrated increases in dysphoria and dysfunctional attitudes in response to the negative mood priming challenge. Dysphoric participants with a history of depression, but not the other two groups, evidenced modest increases in explanatory style following the negative mood priming challenge. Finally, euthymic participants with a history of depression, but not the other two groups, evidenced drops in explanatory flexibility. Findings from the present study suggest that the cognitive theories of depression may benefit from examining both cognitive content and cognitive flexibility when assessing risk for depression.

    Treatment options for multidrug-resistant pathogens remain problematic in many regions and individual countries, warranting ongoing surveillance and analysis. Limited antimicrobial susceptibility information is available for pathogens from Vietnam. This study determined the bacterial susceptibility of aerobic gram-negative pathogens of intra-abdominal infections among patients in Vietnam during 2009-2011. A total of 905 isolates were collected from 4 medical centers in this investigation as part of the Study for Monitoring Antimicrobial Resistance Trends. Antimicrobial susceptibility and extended-spectrum beta-lactamase (ESBL) rates among the appropriate species were determined by a central laboratory using Clinical and Laboratory Standards Institute methods. Among the species collected, Escherichia coli (48.1% ESBL-positive) and Klebsiella pneumoniae (39.5% ESBL-positive) represented the majority (46.4%) of the isolates submitted for this study. Ertapenem MIC90 values were lowest for these 2 species at 0.12 and 0.25μg/mL and remained unchanged for ESBL-positive isolates. Imipenem MIC90 values were also the same for all isolates and ESBL-positive strains at 0.25 and 0.5μg/mL, respectively. Ertapenem MIC90 values for additional species with sufficient numbers for analysis, including Enterobacter cloacae, Proteus mirabilis, Acinetobacter baumannii, and Pseudomonas aeruginosa, were 1, 0.06, >4, and >4μg/mL, respectively. Analysis of beta-lactamases in a subset of 132 phenotypically ESBL-positive Enterobacteriaceae demonstrated that CTX-M variants, particularly CTX-M-27 and CTX-M-15, were the predominant enzymes. High resistance rates in Vietnam hospitals dictate continuous monitoring as antimicrobial inactivating enzymes continue to spread throughout Asia and globally.

To evaluate of Helicobacter PCR in gastric biopsies for the daily diagnostics of Helicobacter-negative gastritis. Over a 5-year period, routine biopsies with chronic gastritis reminiscent of Helicobacter infection, but negative by histology, were tested by using a H. pylori specific PCR. Subsequently, PCR-negative samples were re-evaluated using PCR for other Helicobacter species. Of the 9184 gastric biopsies, 339 (3.7%) with histological-negative gastritis and adequate material were forwarded to PCR analysis for H. pylori and 146 (43.1%) revealed a positive result. In 193 H. pylori DNA-negative biopsies, re-analysis using PCR primers for other Helicobacter species, revealed further 23 (11.9%) positive biopsies, including 4 (2.1%) biopsies with H. heilmannii sensu lato. PCR-positive biopsies showed a higher overall inflammatory score, more lymphoid follicles/aggregates and neutrophils (P gastritis. © 2016 John Wiley & Sons Ltd.

    Resonances can be tuned in dielectric resonators in order to construct single-resonator, negative-index metamaterials. For example, high-contrast inclusions in the form of metallic dipoles can be used to shift the first electric resonance down (in frequency) to the first magnetic resonance, or alternatively, air splits can be used to shift the first magnetic resonance up (in frequency) near the first electric resonance. Degenerate dielectric designs become especially useful in infrared- or visible-frequency applications where the resonator sizes associated with the lack of high-permittivity materials can become of sufficient size to enable propagation of higher-order lattice modes in the resulting medium.

    The generalized matching equation provides a good description of response allocation in concurrent schedules of positive reinforcement in nonhumans as well as in humans. The present experiment was conducted to further investigate the allocation of responding under concurrent schedules of negative reinforcement (i.e., timeouts from pressing a force cell) in humans. Each of three participants was exposed to different reinforcement ratios (9:1, 1:1 and 1:9) in the terminal links of a concurrent-chains schedule of negative reinforcement. The allocation of responding under this schedule was well described by the generalized matching equation, for each participant. These results replicate previous findings obtained with nonhumans and humans under concurrent schedules of positive reinforcement. In addition, they extend the results reported by Alessandri and Rivière (2013) showing that human behavior maintained by timeouts from an effortful response is sensitive to changes in relative reinforcement ratios as well as relative delays of reinforcement.

    Research interest in Na-ion batteries has increased rapidly because of the environmental friendliness of sodium compared to lithium. Throughout this Perspective paper, we report and review recent scientific advances in the field of negative electrode materials used for Na-ion batteries. This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes. Moreover, not only sodiation-active materials but also binders, current collectors, electrolytes and electrode/electrolyte interphase and its stabilization are essential for long cycle life Na-ion batteries. This paper also addresses the prospect of Na-ion batteries as low-cost and long-life batteries with relatively high-energy density as their potential competitive edge over the commercialized Li-ion batteries.

  17. Incidence of carbapenem-resistant gram negatives in Italian transplant recipients: a nationwide surveillance study.

    Full Text Available Bacterial infections remain a challenge to solid organ transplantation. Due to the alarming spread of carbapenem-resistant gram negative bacteria, these organisms have been frequently recognized as cause of severe infections in solid organ transplant recipients.Between 15 May and 30 September 2012 we enrolled 887 solid organ transplant recipients in Italy with the aim to describe the epidemiology of gram negative bacteria spreading, to explore potential risk factors and to assess the effect of early isolation of gram negative bacteria on recipients' mortality during the first 90 days after transplantation. During the study period 185 clinical isolates of gram negative bacteria were reported, for an incidence of 2.39 per 1000 recipient-days. Positive cultures for gram negative bacteria occurred early after transplantation (median time 26 days; incidence rate 4.33, 1.67 and 1.14 per 1,000 recipient-days in the first, second and third month after SOT, respectively. Forty-nine of these clinical isolates were due to carbapenem-resistant gram negative bacteria (26.5%; incidence 0.63 per 1000 recipient-days. Carbapenems resistance was particularly frequent among Klebsiella spp. isolates (49.1%. Recipients with longer hospital stay and those who received either heart or lung graft were at the highest risk of testing positive for any gram negative bacteria. Moreover recipients with longer hospital stay, lung recipients and those admitted to hospital for more than 48h before transplantation had the highest probability to have culture(s positive for carbapenem-resistant gram negative bacteria. Forty-four organ recipients died (0.57 per 1000 recipient-days during the study period. Recipients with at least one positive culture for carbapenem-resistant gram negative bacteria had a 10.23-fold higher mortality rate than those who did not.The isolation of gram-negative bacteria is most frequent among recipient with hospital stays >48 hours prior to transplant

    The goal of this study was to determine whether sleep moderates the associations between family-related stress and depressive symptoms and negative affect outcomes during adolescence. We combined traditional survey measures of stress and depressive symptoms with daily assessments of stress and negative affect to examine whether sleep differentially impacts the link between chronic and acute experiences of stress and affect. Participants were 316 adolescents from ethnically diverse backgrounds. Primary caregivers and adolescents reported on stressful family events during the past 12 and 3 months, respectively. Adolescents also reported on their daily experiences of family demands for 15 days and wore actigraph watches for the assessment of sleep during the first eight nights. Regression analyses revealed that more stressful family events were related to more depressive symptoms. This relation was stronger among adolescents with lower sleep efficiency. The same pattern emerged for the relation between daily family demands and negative affect aggregated across the 15 days. Daily-level analyses indicated that daily negative affect was related to daily family demands when sleep efficiency was higher than usual, but only among European American adolescents. These findings suggest that chronic experiences of lower sleep efficiency, but not sleep duration, may render adolescents more vulnerable to the negative effects of family stress on emotional adjustment. A more complex picture emerged for the role of prior night's sleep in the day-to-day variation in negative affect reactivity to family stress.

  19. Input calibration for negative originals

    Science.gov (United States)

    Tuijn, Chris

    1995-04-01

    One of the major challenges in the prepress environment consists of controlling the electronic color reproduction process such that a perfect match of any original can be realized. Whether this goal can be reached depends on many factors such as the dynamic range of the input device (scanner, camera), the color gamut of the output device (dye sublimation printer, ink-jet printer, offset), the color management software etc. The characterization of the color behavior of the peripheral devices is therefore very important. Photographs and positive transparents reflect the original scene pretty well; for negative originals, however, there is no obvious link to either the original scene or a particular print of the negative under consideration. In this paper, we establish a method to scan negatives and to convert the scanned data to a calibrated RGB space, which is known colorimetrically. This method is based on the reconstruction of the original exposure conditions (i.e., original scene) which generated the negative. Since the characteristics of negative film are quite diverse, a special calibration is required for each combination of scanner and film type.

    Purpose: To retrospectively evaluate the clinical outcome of non-anticoagulated patients with clinically suspected acute pulmonary embolism (PE) and no symptoms or signs of deep venous thrombosis (DVT) following a negative contrast medium-enhanced spiral CT of the pulmonary arteries (s-CTPA). Material and Methods: During a 24-month period, 739 of 751 patients underwent s-CTPA with acceptable diagnostic quality for clinically suspected acute PE. All patients who had a CT study not positive for PE were followed up with a questionnaire, a telephone interview and review of all medical reports, including autopsies and death certificates for any episodes of venous thromboembolism (VTE) during a 3-month period. Results: PE was diagnosed in 158 patients. Of the remaining 581 patients with a negative s-CTPA, 45 patients were lost to follow-up. 88 patients were excluded because of anticoagulation treatment (cardiac disorder n=32, chronic VTE or acute symptomatic DVT n=31, PE diagnosed at pulmonary angiography n=1, thrombus prophylaxis during diagnostic work-up or other reasons than VTE n=24) and 7 patients undergoing lower extremity venous studies because of symptoms of DVT (all negative). Thus, 441 patients with a negative s-CTPA and no DVT symptoms, venous studies or anticoagulant treatment constituted the follow-up cohort. Four of these patients had proven VTE (all PE) during the 3-month follow-up period. Two of the PE episodes contributed to the patient's death. Conclusion: Patients with clinically suspected acute PE, no symptoms or signs of DVT and a negative single slice s-CTPA using 3-5 mm collimation, may safely be left without anticoagulation treatment unless they are critically ill, have a limited cardiopulmonary reserve and/or if a high clinical suspicion remains.
