  2. Moral Personality Growth

    Directory of Open Access Journals (Sweden)

    Jana Kalin

    1998-12-01

    Full Text Available Learning in terms of personality growth is a life-long process, just as personality growth itself is a life-long process. Kalin presents a number of psychological theories and their impact on moral development - which is an integral part of personality growth. The paper further treats the formation and changing of beliefs, and the role of education in the two processes. Great emphasis is put on cognitive theories; Kalin explains those formulated by L. Kohlberg and J. Rest. In discussing the process of shaping and changing one's views, special emphasis is put on the environment, or rather the social group an individual belongs to, and on the influence of personality traits and experience. The paper juxtaposes the influence - strengths and weaknesses - of the psychology of persuasion and education on forming and changing one's views, taken into consideration that views consist of cognitive, emotive and conative dimensions.

    Full Text Available The present study aimed to realize a systematic review of publications about personal growth initiative. A literature review was realized in Bireme, Index Psi, LILACS, PePSIC, Pubmed - Publisher's Medlme, Wiley Online Library, PsycINFO, OneFile, SciVerse ScienceDirect, ERIC, Emerald Journals, PsycARTICLES - American Psychological Association, Directory of Open Access Journals - DOAJ, SAGE Journals, SpringerLink, PLoS, IngentaConnect, IEEE Journals & Magazines and SciELO databases. The literature review was performed from December of 2014 to January of 2015, without stipulating date limits for the publication of the articles. It was found 53 studies, excluded seven, and analyzed 46 researches. The studies aimed to investigate the psychometric properties of personal growth initiative scale and personal growth initiative scale II. The relations of personal initiative growth and others constructs were also evaluated. Furthermore the studies investigated the impact of interventions to promote personal growth initiative. Results of these studies showed that personal growth initiative was positively related to levels of well-being, selfesteem and others positive dimensions, and negatively to anxiety, depression and others negative factors.

    This study examines aspects of case managers' perceived personal growth in their work with consumers. Using a sample of 98 case managers, the psychometric properties of a brief self-report measure of personal growth of case managers were examined. The Case Manager Personal Growth Scale (CMPG) showed good reliability and construct validity as evidenced by negative correlations with scores on professional burnout and positive correlations with personal accomplishment and job satisfaction scores. CMPG scores were unrelated to social desirability scores or caseload size and positively related to age and tenure in the mental health system. Results suggest the strong relevance of the construct of personal growth for case managers.

    IntroductionSalutogenesis and posttraumatic growth represent personal growth and improved functioning as a result of experiencing major challenging events. These developments are not simply resilience (a return to a baseline level of well-being), but positive change in such characteristics as self-understanding, relations with others, personal values, and life goals. Space agencies and space psychologists, primarily concerned with deleterious effects and their countermeasures, have not paid much attention to such beneficial long-term aftereffects of spaceflight. PurposeTo document what changes veterans of the Soviet/Russian space program report as a consequence of their experiences. MethodTwenty retired male cosmonauts Mir and/or ISS cosmonauts filled out relevant self-report questionnaires. Results: Although there was little change in the relative rankings of a list of values, the scale showed an overall increase in the rated importance of all personal values, although only the increase in Self-Direction reached statistical significance. Responses to one of two post-space growth questionnaires based on the Post-Traumatic Growth Inventory (PTGI) were compared to the means of two comparison groups: 152 first-time mothers, and 926 respondents who had experienced various forms of trauma. The cosmonauts reported higher scores on the dimension of New Possibilities when compared to the new mothers and the traumatized group, and higher scores on Personal Strength and Overall PTG compared to the latter. Respondents who had spent more than a year in space, and those who flew on both Mir and ISS, were the most likely to report positive change in the domain Appreciation of Life. The other post-space career questionnaire reflected major changes in Perceptions of the Earth and of Space, and increases on a number of other dimensions, including New Possibilities and Changes in Daily Life, with positive scores that significantly exceeded the original report.

    Approximately half of the variation in wellbeing measures overlaps with variation in personality traits. Studies of non-human primate pedigrees and human twins suggest that this is due to common genetic influences. We tested whether personality polygenic scores for the NEO Five-Factor Inventory (NEO-FFI) domains and for item response theory (IRT) derived extraversion and neuroticism scores predict variance in wellbeing measures. Polygenic scores were based on published genome-wide association (GWA) results in over 17,000 individuals for the NEO-FFI and in over 63,000 for the IRT extraversion and neuroticism traits. The NEO-FFI polygenic scores were used to predict life satisfaction in 7 cohorts, positive affect in 12 cohorts, and general wellbeing in 1 cohort (maximal N = 46,508). Meta-analysis of these results showed no significant association between NEO-FFI personality polygenic scores and the wellbeing measures. IRT extraversion and neuroticism polygenic scores were used to predict life satisfaction and positive affect in almost 37,000 individuals from UK Biobank. Significant positive associations (effect sizes personality domains. PMID:27546527

    2013-07-01

    Avoidant personality disorder (AVPD), like other personality disorders, has historically been construed as a highly stable disorder. However, results from a number of longitudinal studies have found that the symptoms of AVPD demonstrate marked change over time. Little is known about which other psychological systems are related to this change. Although cross-sectional research suggests a strong relationship between AVPD and personality traits, no work has examined the relationship of their change trajectories. The current study sought to establish the longitudinal relationship between AVPD and basic personality traits using parallel process growth curve modeling. Parallel process growth curve modeling was applied to the trajectories of AVPD and basic personality traits from the Longitudinal Study of Personality Disorders (Lenzenweger, M. F., 2006, The longitudinal study of personality disorders: History, design considerations, and initial findings. Journal of Personality Disorders, 20, 645-670. doi:10.1521/pedi.2006.20.6.645), a naturalistic, prospective, multiwave, longitudinal study of personality disorder, temperament, and normal personality. The focus of these analyses is on the relationship between the rates of change in both AVPD symptoms and basic personality traits. AVPD symptom trajectories demonstrated significant negative relationships with the trajectories of interpersonal dominance and affiliation, and a significant positive relationship to rates of change in neuroticism. These results provide some of the first compelling evidence that trajectories of change in PD symptoms and personality traits are linked. These results have important implications for the ways in which temporal stability is conceptualized in AVPD specifically, and PD in general.

    2008-04-01

    The evolution of crystal growth has been crucially dependent on revolutionary innovations and initiatives involving ideas, technology and communication. A personal perspective is presented on some of these aspects in connection with the early history of semiconductors that have helped evolve our knowledge and advance the science and technology of crystal growth. The presentation considers examples from work on germanium, silicon, indium antimonide, gallium arsenide, indium phosphide, gallium phosphide and mercury cadmium telluride. In connection with metal organic vapour phase epitaxy (MOVPE), the influence of adduct purification for alkyls is noted together with the growth of Hg xCd 1-xTe. The role of crystal growth organisations together with initiatives in the publication of the Journal of Crystal Growth (JCG) and the pivotal role of the International Organisation of Crystal Growth (IOCG) are also highlighted in the quest for scientific excellence.

  18. Positive Outcomes Following Bereavement: Paths to Posttraumatic Growth

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Recent theory and research have drawn attention to the need to better understand the positive changes, termed posttraumatic growth, that often occur in bereaved individuals; even as negative emotions related to grief persist. We describe five dimensions of posttraumatic growth and present a model for understanding how the loss of a close other can eventually lead to a recognition of important positive personal changes. Loss, especially unexpected loss, disrupts an individual's beliefs about the world and initiates a process of rebuilding an understanding. During this process, many people come to realise their own strengths, appreciate the impact of their relationships, and have new spiritual insights. A strategy for facilitating growth during clinical work also is described.

    We examined whether current level of personal growth and changes in personal growth predicted treatment response among participants in a partial hospital setting. Patients (N = 269; aged 18-70 years, M = 33.6; 52.4% female) completed measures of personal growth initiative (PGI), valuing personal growth (VPG), and psychological functioning measures at treatment admission and discharge from a partial hospital. PGI and VPG were negatively associated with depression and positively associated with psychological well-being. Baseline PGI and VPG did not predict changes in psychological functioning at discharge. PGI and VPG significantly increased following treatment, and increases were associated with decreases in depression and increases in well-being over and above previously established predictors. Valuing personal growth for intrinsic reasons and active engagement in the personal growth process may be important characteristics to cultivate in psychotherapy as they are malleable and negatively related to depression. © 2018 Wiley Periodicals, Inc.

    2009-12-01

    Full Text Available The impact of traumatic events is well documented within the clinical psychology literature where it is recognized that people who experience traumatic events may go on to develop posttraumatic stress disorder (PTSD. At first glance one might ask what the relevance of positive psychology is to the study of trauma. But a number of literatures and philosophies throughout human history have conveyed the idea that there is personal gain to be found in suffering. The observation that stressful and traumatic events can provoke positive psychological changes is also contained in the major religions of Buddhism, Christianity, Hinduism, Islam, and Judaism. Within existential philosophy and humanistic psychology it has also been recognized that positive changes can come about as a result of suffering. But it is only within the last decade that the topic of growth following adversity has become a focus for empirical work. In this paper I will provide an overview of the subject and the research we have conducted at the Centre for Trauma, Resilience, and Growth (CTRG.

  6. Inflation and Growth: Positive or Negative Relationship?

    Science.gov (United States)

    Berument, Hakan; Inamlik, Ali; Olgun, Hasan

    This study has been motivated by two developments. Firstly, by the vast literature on the relationship between inflation and growth which is abundantly endowed with diverse theoretical explanations and contradictory evidence and by the unique experience of the Turkish economy with inflation and growth. A preliminary examination of the Turkish data pointed to a negative relation between inflation and growth. Moreover, there is a unanimous agreement among the students of the Turkish economy that many factors have contributed to inflation in this country. In view of these facts this paper employs a VAR model which will enable us to identify the sources of the shocks and control for external factors. In addition VAR models have a high predictive power and enable the researcher to observe the impulse response functions. The study employs Generalised Impulse Response analysis. In the empirical experiments oil prices, money supply, government spending and taxes have been taken as the most likely determinants of inflation. The study shows that there is a negative relationship between inflation and output growth in Turkey and that the underlying explanatory factor is the real exchange rate. This result is robust.

    Losing one's spouse is one of the most stressful life events in old age, yet research on positive consequences of overcoming critical life events describes experiences of personal growth for survivors. Because prior studies conceptualized personal growth as a stable accomplishment of an individual, our study challenges this assumption by examining trajectories of personal growth and its links to two aspects of social support. We assume that personal growth is boosted by heightened levels of loss-related social support seeking during early years of widowhood. However, toward the later stages in the bereavement process, we expect personal growth to be fostered by perceived social embeddedness. Data stem from a survey on relationships in later life conducted in 2012, 2014, and 2016 in Switzerland. The final analytical sample consisted of 508 individuals aged 50+ years, who were on average 73 years old and widowed for about 3 years at baseline. Longitudinal explorative factor analyses yielded a 3-factorial solution for personal growth. Random-effects group-specific growth curves were used to examine the trajectories of personal growth and its subdimensions, by different levels of loss-related social support seeking and embeddedness in a supportive network, over the first 8 years of widowhood. Our analyses included time-invariant and time-varying covariates. On average, our findings point to a stable trajectory of personal growth after having become widowed in later life. Group-specific analyses, however, showed different courses in the trajectories for specific subdimensions of personal growth - particularly for spiritual change and appreciation of life. Average marginal effects also yielded group differences by loss-related support seeking in the level of personal growth over time, which highlight the importance of social support seeking, rather than social embeddedness, at all stages of the bereavement process. Findings underline the importance of a longitudinal and

    A total of 1,333 persons in 627 families were surveyed for presence of antibody to adult T-cell leukemia-associated antigen (anti-ATLA). Each person was classified according to the anti-ATLA status (positive for sample 1, negative for sample 2) of the head of household of his or her family. In sample 1, the sex- and age-standardized prevalence of anti-ATLA was 38.5%. This was five times as high as the standardized prevalence in sample 2 (7.8%). There were significant differences in prevalence of anti-ATLA between males in samples 1 and 2 and between females in samples 1 and 2. In every age group, prevalence in sample 1 was greater than that in sample 2 except for males aged 60-69 years. In each of four subareas, families in sample 1 had higher standardized prevalence (29.6-42.5%) than families in sample 2 (6.0-9.7%). Although crude prevalence decreased with family size in sample 1 (62.1-25.4%) as well as in sample 2, indirectly standardized prevalence was almost equal within each sample, regardless of number of family members. The degree of aggregation was independent of locality and family size. These data suggest that anti-ATLA-positive persons aggregate in family units.

  9. Personalized Resource Recommendations using Learning from Positive and Unlabeled Examples

    2016-08-01

    Full Text Available This paper proposes a novel approach for recommending social resources using learning from positive and unlabeled examples. Bookmarks submitted on social bookmarking system delicious1 and artists on online music system last.fm2 are considered as social resources. The foremost feature of this problem is that there are no labeled negative resources/examples available for learning a recommender/classifier. The memory based collaborative filtering has served as the most widely used algorithm for social resource recommendation. However, its predictions are based on some ad hoc heuristic rules and its success depends on the availability of a critical mass of users. This paper proposes model based two-step techniques to learn a classifier using positive and unlabeled examples to address personalized resource recommendations. In the first step of these techniques, naïve Bayes classifier is employed to identify reliable negative resources. In the second step, to generate effective resource recommender, classification and regression tree and least square support vector machine (LS-SVM are exercised. A direct method based on LS-SVM is also put forward to realize the recommendation task. LS-SVM is customized for learning from positive and unlabeled data. Furthermore, the impact of feature selection on our proposed techniques is also studied. Memory based collaborative filtering as well as our proposed techniques exploit usage data to generate personalized recommendations. Experimental results show that the proposed techniques outperform existing method appreciably.

  11. Coping with Childbirth: Brain Structural Associations of Personal Growth Initiative

    2017-10-01

    Full Text Available Major life events require psychological adaptations and can be accompanied by brain structural and functional changes. The goal of the current study was to investigate the association of personal growth initiative (PGI as a form of proactive coping strategy before childbirth, with gray matter volume after delivery. Childbirth is one of the few predictable major life events, which, while being one of the most positive experiences for many, is also accompanied by multidimensional stress for the mother. Previous research has shown that high stress is associated with reductions in gray matter volume in limbic cortices as well as the prefrontal cortex (PFC. We hypothesized that PGI before childbirth is positively related to gray matter volume after delivery, especially in the ventromedial PFC (vmPFC. In a prospective study, 22 first-time mothers answered questionnaires about their PGI level 1 month before birth (T1 and 1 month after delivery (T2. Four months after giving birth, a follow-up assessment was applied with 16 of these mothers (T3. Structural brain data were acquired at both postpartal measurement occasions. Voxel-based morphometry was used to correlate prenatal PGI levels with postpartal gray matter volume. Higher PGI levels before delivery were positively associated with larger gray matter volume in the vmPFC directly after childbirth. Previous structural neuroimaging research in the context of major life events focused primarily on pathological reactions to stress (e.g., post-traumatic stress disorder; PTSD. The current study gives initial indications that proactive coping may be positively associated with gray matter volume in the vmPFC, a brain region which shows volumetric reductions in PTSD patients.

    The purpose of the research was to investigate the role of personal resources, such as optimism and sense of selfefficacy in both negative (posttraumatic stress disorder (PTSD) symptoms) and positive (posttraumatic growth - PTG) effects of experienced trauma in a group of emergency service representatives. Data of 100 medical rescue workers, mostly men (59%) who have experienced traumatic events in their worksite were analyzed. The age of the participants ranged from 24 to 60 years (mean = 37.43; standard deviation = 8.73). Polish versions of the Impact of Event Scale - Revised and the Posttraumatic Growth Inventory were used to assess the negative and positive effects of experienced events. Optimism was assessed by the Life Orientation Test and sense of self-efficacy by the Generalized Self-Efficacy Scale. The obtained results revealed that optimism is negatively associated with symptoms of PTSD in men, and sense of self-efficacy - positively with the severity of growth after trauma in women. The analyzed personal resources play a diverse role in the emergence of negative and positive effects of experienced traumatic events, depending on the gender of the respondents.

    Students' attitudes towards teaching and learning must be addressed with the same seriousness and effort as we address content. Establishing a personal connection and addressing our students' basic psychological needs will produce positive attitudes towards teaching and learning and develop life-long learners. It will also promote constructive student-teacher relationships that have a profound influence on our students' approach towards school. To begin this process, consider the major tenets of the Self-Determination Theory. The Self-Determination Theory of human motivation focuses on our students' innate psychological needs and the degree to which an individual's behavior is self-motivated and self-determined. Faculty can satisfy the innate psychological needs by addressing our students' desire for relatedness, competence and autonomy. Relatedness refers to our students' need to feel connected to others, to be a member of a group, to have a sense of communion and to develop close relationships with others. Competence is believing our students can succeed , challenging them to do so and imparting that belief in them. Autonomy involves considering the perspectives of the student and providing relevant information and opportunities for student choice and initiating and regulating their own behaviors. Establishing a personal connection and addressing our students' basic psychological needs will improve our teaching, inspire and engage our students and promote positive attitudes towards teaching and learning while reducing competition and increasing compassion. These are important goals because unless students are inspired and motivated and have positive attitudes towards teaching and learning our efforts will fail to meet their full potential.

    2012-01-01

    We formulate and test a model that allows sharp separation between two different ways in which environment affects evaluation of outcomes, by comparing social vs. private and personal responsibility vs. chance. In the experiment, subjects chose between two lotteries, one low-risk and one high-risk. They could then observe the outcomes. By varying the environment between private (they could observe the outcome of the chosen lottery and the outcome of the lottery they had not chosen) and social (they could observe the outcome of the lottery chosen by another subject) we can differentiate the response and brain activity following the feedback in social and private settings. The evidence suggests that envy and pride are significant motives driving decisions and outcomes evaluation, stronger than private emotions like regret and rejoice, with ventral striatum playing a key role. When we focus on the outcome evaluation stage we demonstrate that BOLD signal in ventral striatum is increasing in the difference between obtained and counterfactual payoffs. For a given difference in payoffs, striatal responses are more pronounced in social than in private environment. Moreover, a positive interaction (complementarity) between social comparison and personal responsibility is reflected in the pattern of activity in the ventral striatum. At decision stage we observe getting ahead of the Joneses effect in ventral striatum with subjective value of risk larger in social than in private environment.

    2016-01-01

    We examine the implications of health and personality characteristics for late-life marital conflict, using data from the 2010–11 wave of the National Social Life Health and Aging Project (NSHAP), a nationally representative study with data on both partners in 955 marital and cohabitational dyads. Using these data, we relate characteristics of husbands to characteristics of their wives, and vice versa. Wives with husbands in fair or poor physical health are more likely to report high levels of marital conflict, but the reverse is not true. Similarly, wives report more conflict when their husbands are high on Neuroticism, high on Extraversion, and low on a new measure we call Positivity. Our findings point to noteworthy gender differences between men and women in the associations between individual characteristics and levels of marital conflict. We point to differences between husbands’ and wives’ marital roles as a contributor to these differences. PMID:27274569

    2017-04-01

    The current study aimed at investigating the direct and moderating role of personal growth in a child's adjustment to first grade as perceived by the parents, drawing on Positive Psychology (Seligman & Csikszentmihalyi, ) and the theory of families as systems (Cox & Paley, ). The sample consisted of 280 Israeli parents (213 mothers and 67 fathers) whose children were in first grade. The participants completed questionnaires relating to background variables of the parent and child, as well as parents' perceived stress, emotional intelligence, perceived child's adjustment to school and personal growth. The findings indicate that a child's entrance into the school system may lead to personal growth in the parents and that variables of both the parent (age and education) and the child (birth order) contribute to this process. Furthermore, among parents with a low level of personal growth, higher emotional intelligence was associated with a more positive assessment of the child's adjustment. The study thus demonstrates that the transition to first grade may serve as a lever for the parents' growth and development, which in turn may affect their perception of their child's adjustment to school.

  1. Attachment styles and personal growth following romantic breakups: the mediating roles of distress, rumination, and tendency to rebound.

    Directory of Open Access Journals (Sweden)

    Tara C Marshall

    Full Text Available The purpose of this research was to examine the associations of attachment anxiety and avoidance with personal growth following relationship dissolution, and to test breakup distress, rumination, and tendency to rebound with new partners as mediators of these associations. Study 1 (N = 411 and Study 2 (N = 465 measured attachment style, breakup distress, and personal growth; Study 2 additionally measured ruminative reflection, brooding, and proclivity to rebound with new partners. Structural equation modelling revealed in both studies that anxiety was indirectly associated with greater personal growth through heightened breakup distress, whereas avoidance was indirectly associated with lower personal growth through inhibited breakup distress. Study 2 further showed that the positive association of breakup distress with personal growth was accounted for by enhanced reflection and brooding, and that anxious individuals' greater personal growth was also explained by their proclivity to rebound. These findings suggest that anxious individuals' hyperactivated breakup distress may act as a catalyst for personal growth by promoting the cognitive processing of breakup-related thoughts and emotions, whereas avoidant individuals' deactivated distress may inhibit personal growth by suppressing this cognitive work.

    It has been hypothesized that Helicobacter pylori (Hp) infection may contribute to reduced stature, risk of hypertension or obesity. The aim was to evaluate body indices in Hp positive and negative persons. A total of 2436 subjects (4-100 years old) were tested for Hp status by 13 C-urea breath test. Data on height and weight were collected for 84%, and blood pressure for 80% of the study subjects. The prevalence of Hp infection was 41.6%. The odds ratio for a 10-year increase in age was 1.21 (95% CI 1.17-1.25, p-value <0.001). Statistically significant negative association of Hp positivity with body height was most pronounced in the younger age groups, while a positive association of Hp positivity with body mass index was only seen in those aged 15+ years. There was a negative effect of Hp positivity on systolic and diastolic blood pressure in subjects below 25 and a relatively strong positive effect on blood pressure in subjects over 65 years. Residual confounding by social characteristics as a possible explanation for the associations of Hp positivity with height and blood pressure cannot be excluded. Unmeasured factors related to social and family environment may cause the apparent association between Hp positivity and children's growth and blood pressure

    2015-06-01

    There has been increasing interest in growth approaches to students' academic development, including value-added models, modelling of academic trajectories, growth motivation orientations, growth mindsets, and growth goals. This study sought to investigate the relationships between implicit theories about intelligence (incremental and entity theories) and growth (personal best, PB) goals - with particular interest in the ordering of factors across time. The study focused on longitudinal data of 969 Australian high school students. The classic cross-lagged panel design (using structural equation modelling) was employed to shed light on the ordering of Time 1 growth goals, incremental theories, and entity theories relative to Time 2 (1 year later) growth goals, incremental theories, and entity theories. Findings showed that Time 1 growth goals predicted Time 2 incremental theories (positively) and entity theories (negatively); Time 1 entity and incremental theories negatively predicted Time 2 incremental and entity theories respectively; but, Time 1 incremental theories and entity theories did not predict growth goals at Time 2. This suggests that entity and incremental theories are negatively reciprocally related across time, but growth goals seem to be directionally salient over incremental and entity theories. Implications for promoting growth goals and growth mindsets are discussed. © 2014 The British Psychological Society.

    Purpose Human epidermal growth factor receptor 2 (HER2)-positive/hormone receptor (HR)-positive breast cancer is a distinct subgroup associated with lower chemotherapy sensitivity and slightly better outcome than HER2-positive/HR-negative disease. Little is known about the efficacy of the combination of endocrine therapy (ET) with trastuzumab or with the potent antibody-cytotoxic, anti-HER2 compound trastuzumab emtansine (T-DM1) with or without ET for this subgroup. The West German Study Group trial, ADAPT (Adjuvant Dynamic Marker-Adjusted Personalized Therapy Trial Optimizing Risk Assessment and Therapy Response Prediction in Early Breast Cancer) compares pathologic complete response (pCR) rates of T-DM1 versus trastuzumab with ET in early HER2-positive/HR-positive breast cancer. Patients and Methods In this prospective, neoadjuvant, phase II trial, 375 patients with early breast cancer with HER2-positive and HR-positive status (n = 463 screened) were randomly assigned to 12 weeks of T-DM1 with or without ET or to trastuzumab with ET. The primary end point was pCR (ypT0/is/ypN0). Early response was assessed in 3-week post-therapeutic core biopsies (proliferation decrease ≥ 30% Ki-67 or cellularity response). Secondary end points included safety and predictive impact of early response on pCR. Adjuvant therapy followed national standards. Results Baseline characteristics were well balanced among the arms. More than 90% of patients completed the therapy per protocol. pCR was observed in 41.0% of patients treated with T-DM1, 41.5% of patients treated with T-DM1 and ET, and 15.1% with trastuzumab and ET ( P < .001). Early responders (67% of patients with assessable response) achieved pCR in 35.7% compared with 19.8% in nonresponders (odds ratio, 2.2; 95% CI, 1.24 to 4.19). T-DM1 was associated with a significantly higher prevalence of grade 1 to 2 toxicities, especially thrombocytopenia, nausea, and elevation of liver enzymes. Overall toxicity was low; seventeen

    This research developed and tested an online values-affirmation exercise to attenuate threat and enhance positive beliefs about counseling among individuals struggling with mental health concerns. There is evidence that reflecting on personal values (values-affirmation) is an effective approach to eliciting self-affirmation-a psychological process that temporarily bolsters self-worth in order to forestall maladaptive, self-protective responses to counseling information. The present study utilized a randomized 2-group between-subjects design to test the effectiveness of a values-affirmation exercise with an online sample (N = 186) of adults who reported struggling with a mental health concern. It was predicted that values-affirmation would reduce threat related to reading mental health information and increase positive beliefs about counseling. Results indicated that those in the values-affirmation condition reported fewer negative emotions such as feeling upset, irritable, hostile, and scared after reading mental health information, indicating that the information was perceived as less threatening. There was also evidence that engaging in values-affirmation was associated with greater anticipated growth in counseling and greater intent to seek counseling, reflecting greater positive beliefs about counseling. Overall, the results suggest that reflecting on personal values may have the potential to enhance the positive effects of online psychoeducation.

    Turner syndrome occurs in phenotypic females with complete or partial absence of X chromosome. The leading symptom is short stature, while numerous but mild stigmata manifest in the craniofacial region. These patients are commonly treated with growth hormone to improve their final height. The aim of this study was to assess the influence of long-term growth hormone therapy on craniofacial morphology in Turner syndrome patients. In this cross-sectional study cephalometric analysis was performed on 13 lateral cephalograms of patients with 45,X karyotype and the average age of 17.3 years, who have received growth hormone for at least two years. The control group consisted of 13 Turner syndrome patients naive to growth hormone treatment, matched to study group by age and karyotype. Sixteen linear and angular measurements were obtained from standard lateral cephalograms. Standard deviation scores were calculated in order to evaluate influence of growth hormone therapy on craniofacial components. In Turner syndrome patients treated with growth hormone most of linear measurements were significantly larger compared to untreated patients. Growth hormone therapy mainly influenced posterior face height, mandibular ramus height, total mandibular length, anterior face height and maxillary length. While the increase in linear measurements was evident, angular measurements and facial height ratio did not show statistically significant difference. Acromegalic features were not found. Long-term growth hormone therapy has positive influence on craniofacial development in Turner syndrome patients, with the greatest impact on posterior facial height and mandibular ramus. However, it could not compensate X chromosome deficiency and normalize craniofacial features. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The desire for power is personal. Competence and political intelligence are the prerequisites for handling power in a healthy manner. Politics is not a nasty word or a set of behaviors that inevitably turns you into a shady character of whom your mother would be ashamed. You need never divorce your own morality from the situation. The choice to improve your political functioning is yours. You always retain the right to play, and you retain the right to decide when to play. But you are a better manager, a better professional, and a more educated person if you can identify what others are doing and how their behavior will impact you. It is not just for success, it is for survival--success and survival on your own terms.

  9. Identifying Latent Trajectories of Personality Disorder Symptom Change: Growth Mixture Modeling in the Longitudinal Study of Personality Disorders

    2013-01-01

    Although previous reports have documented mean-level declines in personality disorder (PD) symptoms over time, little is known about whether personality pathology sometimes emerges among nonsymptomatic adults, or whether rates of change differ qualitatively among symptomatic persons. Our study sought to characterize heterogeneity in the longitudinal course of PD symptoms with the goal of testing for and describing latent trajectories. Participants were 250 young adults selected into two groups using a PD screening measure: those who met diagnostic criteria for a DSM-III-R PD (PPD, n = 129), and those with few PD symptoms (NoPD, n = 121). PD symptoms were assessed three times over a four-year study using semistructured interviews. Total PD symptom counts and symptoms of each DSM-III-R PD were analyzed using growth mixture modeling. In the NoPD group, latent trajectories were characterized by stable, minor symptoms; the rapid or gradual remission of subclinical symptoms; or the emergence of symptoms of Avoidant, Obsessive-Compulsive, or Paranoid PD. In the PPD group, three latent trajectories were evident: rapid symptom remission, slow symptom decline, or a relative absence of symptoms. Rapid remission of PD symptoms was associated with fewer comorbid disorders, lower negative emotionality, and greater positive emotionality and constraint, whereas emergent personality dysfunction was associated with comorbid PD symptoms and lower positive emotionality. In most cases, symptom change for one PD was associated with concomitant changes in other PDs, depressive symptoms, and anxiety. These results indicate that the longitudinal course of PD symptoms is heterogeneous, with distinct trajectories evident for both symptomatic and nonsymptomatic individuals. The prognosis of PD symptoms may be informed by an assessment of personality and comorbid psychopathology. PMID:23231459

    Research on developmental trajectories of early maladaptive features for understanding later personality disorders (PDs) is increasingly recognized as an important study area. The course of early odd features is highly relevant in this regard, as only a few researchers have addressed childhood oddity in the context of emerging PDs. Using latent growth modeling, the current study explores growth parameters of odd features in a mixed sample of Flemish community and referred children (N = 485) across three measurement waves with 1-year time intervals. Personality pathology was assessed at a fourth assessment point in adolescence. Beyond a general declining trend in oddity characteristics, the results demonstrated that both an early onset and an increasing trend of oddity-related characteristics over time are independent predictors of adolescent PDs. Childhood oddity tends to be the most manifest precursor for PDs with a core oddity feature (i.e., the schizotypal and borderline PD), but also appears to predict most of the other DSM-5 PDs. Results are discussed from an overarching developmental framework on PDs (Cicchetti, 2014), specifically focusing on the principle of multifinality. From a clinical perspective, the significance of increasing or steady-high childhood oddity trajectories for adolescent PDs highlights the relevance of systematic screening processes across time.

    Emerging preclinical evidence suggests that androgen-mediated androgen receptor (AR) signals promote bladder cancer progression. However, little is known about the efficacy of an AR signaling inhibitor, enzalutamide, in the growth of bladder cancer cells. In this study, we compared the effects of enzalutamide and 2 other classic antiandrogens, flutamide and bicalutamide, on androgen-induced bladder cancer cell proliferation, migration, and invasion as well as tumor growth in vivo. Thiazolyl blue cell viability assay, flow cytometry, scratch wound-healing assay, transwell invasion assay, real-time polymerase chain reaction, and reporter gene assay were performed in AR-positive (e.g., UMUC3, TCCSUP, and 647V-AR) and AR-negative (e.g., UMUC3-AR-short hairpin RNA [shRNA], TCCSUP-AR-shRNA, 647V) bladder cancer lines treated with dihydrotestosterone and each AR antagonist. We also used a mouse xenograft model for bladder cancer. Dihydrotestosterone increased bladder cancer cell proliferation, migration, and invasion indicating that endogenous or exogenous AR was functional. Enzalutamide, hydroxyflutamide, and bicalutamide showed similar inhibitory effects, without significant agonist activity, on androgen-mediated cell viability/apoptosis, cell migration, and cell invasion in AR-positive lines. No significant effects of dihydrotestosterone as well as AR antagonists on the growth of AR-negative cells were seen. Correspondingly, in UMUC3 cells, these AR antagonists down-regulated androgen-induced expression of AR, matrix metalloproteinase-2, and interleukin-6. Androgen-enhanced AR-mediated transcriptional activity was also blocked by each AR antagonist exhibiting insignificant agonist activity. In UMUC3 xenograft-bearing mice, oral gavage treatment with each antiandrogen retarded tumor growth, and only enzalutamide demonstrated a statistically significant suppression compared with mock treatment. Our current data support recent observations indicating the involvement of

    2018-06-01

    ABSTRACTObjective:Compassion fatigue, burnout, and vicarious traumatization are prominent topics in the current literature on the impact of the rewarding but challenging work of healthcare professionals who care for patients with life-limiting illnesses. The positive effects of caregiving constitute a newly emerging outcome that has been relatively unexplored in the pediatric literature, and yet they may play an important role in contributing to the satisfaction and well-being of the healthcare professionals who care for children who have a life-limiting illness. This paper reports the results of a secondary analysis of qualitative interview transcripts that explored the experiences of hospital-based pediatric healthcare providers caring for children with varied life-limiting illnesses. In-depth qualitative interviews were conducted with 25 healthcare professionals (9 social workers, 8 nurses, and 8 physicians). The majority of participants were women (80%), with an age range between 20 and 60 years, and most (84%) had the experience of caring for more than 15 dying children. Thematic analysis was conducted using interpretive description and constant comparison. Every healthcare professional interviewed experienced personal growth as a result of their providing care for dying children. Three dimensions of personal growth were most consistently reported: (1) new or altered life perspectives, (2) enhanced personal resources, and (3) benevolence. A deeper understanding of the phenomenon of personal growth could help healthcare organizations to implement innovative approaches that would counterbalance compassion fatigue, and thereby enhance both healthcare provider well-being and child and family outcomes.

    Full Text Available The command of active and autonomous life-forming is a value which is rapidly gaining ground nowadays. All the knowledge, acquired during the formal educational process, is worth only if one knows how to make use of it. To be able to do this, one has to have a profound understanding of him-/herself. In the past the spiritual core of people was the domain of various religions. But the time has come when also medicine, psychology, and pedagogy should start paying attention to these issues. In the process of personal growth one develops the consciousness about him-/her self. The capacity of taking decisions is in close relation to personal maturity and is not dependent on forma!education and the amount of knowledge one possesses. The essence of the edu­ cational programme of Gama - School for Stable Life is based upon depth meditation, which enables one to make a profound contact with his/her own spiritual core.

    The aim of this study is to evaluate the correlation between clinical features of benign paroxysmal positional vertigo (BPPV) and age, sex, trauma, presence of one or more comorbidities such as cardiovascular, neurological, endocrinological, metabolic, psychiatric diseases. Retrospective review of medical records (chart review). A total of 475 patients aged from 14 to 87 years, affected by BPPV. Recurrence of BPPV occurred in 139/475 patients (29.2%). The recurrence rate was significantly higher in female and older patients. Comorbidities were present in 72.6% of subjects with recurrent BPPV vs. 48.9% of patients with no recurrence (p disorders, followed by neurological and vascular diseases. Collecting a complete medical history is important for prognostic stratification and detection of potential underlying pathological conditions.

    Growing evidence from field studies has linked daily stressors to dysregulated patterns of diurnal cortisol. Less is known about whether naturally-occurring positive events in everyday life are associated with diurnal cortisol. The objectives of this study were to evaluate daily positive events as predictors of between-person differences and within-person (day-to-day) variations in diurnal cortisol parameters, in addition to daily positive events as buffers against the associations between daily stressors and cortisol. In the National Study of Daily Experiences, 1657 adults ages 33-84 (57% female) reported daily experiences during telephone interviews on 8 consecutive evenings. Saliva samples were collected 4 times per day on 4 interview days and assayed for cortisol. Multilevel models were used to estimate associations of daily positive events with cortisol awakening response (CAR), diurnal cortisol slope, and area under the curve (AUC). At the between-person level, people who experienced more frequent positive events exhibited a steeper diurnal cortisol slope, controlling for daily stressors, daily affect, and other covariates. At the within-person level, positive events in the morning (but not prior-night or afternoon/evening events) predicted steeper decline in cortisol across that day; positive events were also marginally associated with lower same-day AUC. Associations were not mediated by daily positive affect, and positive events did not buffer against stressor-related cortisol alterations. These findings indicate that individual differences and day-to-day variations in daily positive events are associated with diurnal cortisol patterns, independent of stressors and affect.

    Research on posttraumatic growth (PTG), positive psychological changes that may occur as a result of highly stressful life events, reveals adolescents are able to experience PTG. The current study tests individual differences among adolescents in relative importance of PTG and examines the relationships among personally important PTG, commonly defined PTG, and self-esteem. Adolescents (N = 145) with the mean age of 15.75 (SD = 1.13) completed the Rosenberg Self-Esteem Scale and PTG Inventory, and then reported which items on the PTG Inventory were personally important to them. Results indicated within-scale differences in item importance on the PTG Inventory. Personally important PTG was a better predictor of adolescent self-esteem than commonly defined PTG, measured as total PTGI score or each of the five factors. These findings suggest future research should look at both short-term and long-term effects of personally important PTG as well as commonly defined PTG.

    Full Text Available The present study examined the relationships between four personality traits, humor styles, and happiness. Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life.

    Full Text Available The origins of Molecular Biology and Bacterial Physiology are reviewed, from our personal standpoints, emphasizing the coupling between bacterial growth, chromosome replication and cell division, dimensions and shape. Current knowledge is discussed with historical perspective, summarizing past and present achievements and enlightening ideas for future studies. An interactive simulation program of the Bacterial Cell Division Cycle (BCD, described as The Central Dogma in Bacteriology, is briefly represented. The coupled process of transcription/translation of genes encoding membrane proteins and insertion into the membrane (so-called transertion is invoked as the functional relationship between the only two unique macromolecules in the cell, DNA and peptidoglycan embodying the nucleoid and the sacculus respectively. We envision that nucleoid complexity, defined as the weighted-mean DNA content associated with the replication terminus, is directly related to cell shape through the transertion process. Accordingly, the primary signal for cell division transmitted by DNA dynamics (replication, transcription and segregation to the peptidoglycan biosynthetic machinery is of a physico-chemical nature, eg stress in the plasma membrane, relieving nucleoid occlusion in the cell's center hence enabling the divisome to assemble and function between segregated daughter nucleoids.

    Hall, Erika V; Galinsky, Adam D; Phillips, Katherine W

    2015-06-01

    The current research integrates perspectives on gendered race and person-position fit to introduce the concept of a gender profile. We propose that both the "gender" of a person's biological sex and the "gender" of a person's race (Asians are perceived as feminine and Blacks as masculine) help comprise an individual's gender profile-the overall femininity or masculinity associated with their demographic characteristics. We also propose that occupational positions have gender profiles. Finally, we argue that the overall gender profile of one's demographics, rather than just one's biological sex, determines one's fit and hirability for feminine or masculine occupational roles. The current five studies establish the gender profiles of different races and sexes, and then demonstrate that individuals with feminine-typed and masculine-typed gender profiles are selected for feminine and masculine positions, respectively. These studies provide new insights on who gets ahead in different environments. © 2015 by the Society for Personality and Social Psychology, Inc.

    We investigated the relationships among positivity, perceived personal and environmental resources, and emotional dysfunction in adolescent girls. We hypothesized that perceived resources would mediate the relationship between positivity and emotional dysfunction. Participants (N = 510) attending an all-girls public school completed a survey assessing emotional dysfunction (depressive symptoms and perceived stress), positivity (positive/negative emotions), and personal/ environmental resources (resilience, hope, percent adaptive coping, community connectedness, social support, and school connectedness). Perceived resources were combined into one latent variable, and structural equation modeling tested the mediating effect of perceived resources on the relationship between positivity and emotional dysfunction. The model accounted for 63% of the variance in emotional dysfunction. Positivity exerted a significant direct effect on emotional dysfunction (β = -.14, p emotional dysfunction is primarily but not entirely mediated by perceived personal and environmental resources. Schools should consider strategies to enhance experiences of positive emotions and/or decrease experiences of negative emotions, in conjunction with encouraging student awareness and development of personal and environmental resources.

J Strength Cond Res 23(5): S1-S59, 2009-Perceived yet often misunderstood demands of a sport, overt benefits of anabolic drugs, and the inability to be offered any effective alternatives has fueled anabolic drug abuse despite any consequences. Motivational interactions with many situational demands including the desire for improved body image, sport performance, physical function, and body size influence and fuel such negative decisions. Positive countermeasures to deter the abuse of anabolic drugs are complex and yet unclear. Furthermore, anabolic drugs work and the optimized training and nutritional programs needed to cut into the magnitude of improvement mediated by drug abuse require more work, dedication, and preparation on the part of both athletes and coaches alike. Few shortcuts are available to the athlete who desires to train naturally. Historically, the NSCA has placed an emphasis on education to help athletes, coaches, and strength and conditioning professionals become more knowledgeable, highly skilled, and technically trained in their approach to exercise program design and implementation. Optimizing nutritional strategies are a vital interface to help cope with exercise and sport demands (). In addition, research-based supplements will also have to be acknowledged as a strategic set of tools (e.g., protein supplements before and after resistance exercise workout) that can be used in conjunction with optimized nutrition to allow more effective adaptation and recovery from exercise. Resistance exercise is the most effective anabolic form of exercise, and over the past 20 years, the research base for resistance exercise has just started to develop to a significant volume of work to help in the decision-making process in program design (). The interface with nutritional strategies has been less

    2012-05-01

    Centenarians have been reported to share particular personality traits including low neuroticism and high extraversion and conscientiousness. Since these traits have moderate to high heritability and are associated with various health outcomes, personality appears linked to bio-genetic mechanisms which may contribute to exceptional longevity. Therefore, the present study sought to detect genetically-based personality phenotypes in a genetically homogeneous sample of centenarians through developing and examining psychometric properties of a brief measure of the personality of centenarians, the Personality Outlook Profile Scale (POPS). The results generated two personality characteristics/domains, Positive Attitude Towards Life (PATL: optimism, easygoing, laughter, and introversion/outgoing) and Emotional Expression (EE: expressing emotions openly and not bottling up emotions). These domains demonstrated acceptable concurrent validity with two established personality measures, the NEO-Five Factor Inventory and Life Orientation Test-Revised. Additionally, centenarians in both groups had lower neuroticism and higher conscientiousness than the US adult population. Findings suggest that the POPS is a psychometrically sound measure of personality in centenarians and capture personality aspects of extraversion, neuroticism, and conscientiousness, as well as dispositional optimism which may contribute to successful aging.

    Two-year-olds produce third person singular -s more accurately on verbs in sentence-final position as compared with verbs in sentence-medial position. This study was designed to determine whether these sentence-position effects can be explained by perceptual factors. For this purpose, the authors compared 22- and 27-month-olds' perception and elicited production of third person singular -s in sentence-medial versus-final position. The authors assessed perception by measuring looking/listening times to a 1-screen display of a cartoon paired with a grammatical versus an ungrammatical sentence (e.g., She eats now vs. She eat now). Children at both ages demonstrated sensitivity to the presence/absence of this inflectional morpheme in sentence-final, but not sentence-medial, position. Children were also more accurate at producing third person singular -s sentence finally, and production accuracy was predicted by vocabulary measures as well as by performance on the perception task. These results indicate that children's more accurate production of third person singular -s in sentence-final position cannot be explained by articulatory factors alone but that perceptual factors play an important role in accounting for early patterns of production. The findings also indicate that perception and production of inflectional morphemes may be more closely related than previously thought.

    2011-09-01

    The human tendency to use positive words ("adorable") more often than negative words ("dreadful") is called the linguistic positivity bias. We find evidence for this bias in two studies of word use, one based on written corpora and another based on naturalistic speech samples. In addition, we demonstrate that the positivity bias applies to nouns and verbs as well as adjectives. We also show that it is found to the same degree in written as well as spoken English. Moreover, personality traits and gender moderate the effect, such that persons high on extraversion and agreeableness and women display a larger positivity bias in naturalistic speech. Results are discussed in terms of how the linguistic positivity bias may serve as a mechanism for social facilitation. People, in general, and some people more than others, tend to talk about the brighter side of life.

    Approximately 2.8 million people in the United States are diagnosed with autism spectrum disorder (ASD). Family caregivers manage many aspects of their care, which is demanding, overwhelming, and can affect their mental health. This study examined the effects of caregiver burden (risk factor) and positive cognitions (protective factors) on resourcefulness (resilience indicator) in 95 caregivers of persons with ASD. Descriptive, correlational, and cross-sectional. Positive cognitions explained 32% of the variance in resourcefulness, F(1, 93) = 44.49, p caregivers' resourcefulness increased. A substantial drop in the beta weight of caregiver burden from B = -.36 to -.04 when positive cognitions was entered the equation suggested that positive cognitions mediated the effect of caregiver burden on resourcefulness. The results support resilience theory and suggest a need for developing interventions to strengthen positive thinking among caregivers of persons with ASD.

  2. Gratitude, hope, mindfulness and personal-growth initiative: buffers or risk factors for problem gambling?

    Directory of Open Access Journals (Sweden)

    Jasmine M Y Loo

    Full Text Available The majority of prevention and intervention research in problem gambling (PG has focused on identifying negative risk factors. However, not all at-risk individuals go on to develop anticipated disorders and many thrive in spite of them. In healthcare settings, PG and other disorders are typically conceptualized from the biomedical perspective that frame disorders as something negative residing within the individual and reduction in negativity is seen as success. Indeed, this problem-focused conceptualization may be adequate in many cases as reducing PG behaviour is undoubtedly an important outcome, but the focus on negativity alone is too narrow to capture the complexity of human behaviour. Hence, this study attempts to bridge the gap in literature by providing an evaluation of the predictive ability of the positive dispositions on problem gambling severity, gambling-related cognitions, and gambling urges. The positive psychological dispositions examined were curiosity, gratitude, hope, personal growth initiative, and mindfulness. Participants consisted of 801 Taiwanese Chinese students and community individuals (Mean age = 25.36 years. Higher levels of gratitude and hope have been found to predict lower PG, gambling-related cognitions, or gambling urges. Meanwhile, higher mindfulness predicted lower PG, but only among Chinese males. However, lower personal growth initiative predicted lower PG, gambling-related cognitions, and gambling urges. These analyses have small to medium effect sizes with significant predictions. Findings of this study have essential implications in understanding and treating Chinese problem gamblers. These positive dispositions should be addressed by mental health professionals in preventative and treatment programs among Chinese individuals. Further implications and suggestions for future research are discussed.

    This study extends the literature on personality and job performance through the use of random coefficient modeling to test the validity of the Big Five personality traits in predicting overall sales performance and sales performance trajectories--or systematic patterns of performance growth--in 2 samples of pharmaceutical sales representatives at maintenance and transitional job stages (K. R. Murphy, 1989). In the maintenance sample, conscientiousness and extraversion were positively associated with between-person differences in total sales, whereas only conscientiousness predicted performance growth. In the transitional sample, agreeableness and openness to experience predicted overall performance differences and performance trends. All effects remained significant with job tenure statistically controlled. Possible explanations for these findings are offered, and theoretical and practical implications of findings are discussed.

    This article examines state legislators' public position on gay and lesbian rights by using responses to survey data on their positions toward civil unions and inclusion of sexual orientation in anti-job discrimination laws. The research finds that although state legislators are mixed on their positions, they are less supportive of gay and lesbian rights than is the general public. It also finds that their public positions are a product of both their personal beliefs and values as well as their political calculations. The implications of these findings are explored.

    2016-01-01

    Objectives This study was conducted to characterize the relative strength of associations of learning environment perception with academic performance and with personal growth. Methods In 2012-2014 second and third year students at Johns Hopkins University School of Medicine completed a learning environment survey and personal growth scale. Hierarchical linear regression analysis was employed to determine if the proportion of variance in learning environment scores accounted for by personal growth was significantly larger than the proportion accounted for by academic performance (course/clerkship grades). Results The proportion of variance in learning environment scores accounted for by personal growth was larger than the proportion accounted for by academic performance in year 2 [R2Δ of 0.09, F(1,175) = 14.99,  p environment scores shared a small amount of variance with academic performance in years 2 and 3.  The amount of variance between learning environment scores and personal growth was small in year 2 and large in year 3. Conclusions Since supportive learning environments are essential for medical education, future work must determine if enhancing personal growth prior to and during the clerkship year will increase learning environment perception.

    2013-10-01

    Full Text Available We reveal the psychological mechanisms of impact of the formation level of the teacher’s positive values on the academic performance of students, one of the key components of which are the emotional states of students. We describe a study aimed to test the hypothesis that the positive values and standing behind them “strong” character traits of the teacher determine the emotional states specific of his students during the lesson. The study involved 241 teachers of school subjects and 498 pupils of VI, VIII, X, XI grades of several schools in Krivoy Rog. The study demonstrated that a high level of expression of teacher’s positive values, reflected in his professional qualities, provide the appearance of positive emotional states of students. We also revealed patterns of influence of teacher’s positive personal resource on the intensity of the emotional states experienced by students during lessons.

Angiogenesis is a complicated process in oncogenesis regulated by the balance between angiogenic and antiangiogenic factors. The expression of two angiogenic growth factors, vascular endothelial growth factor and basic fibroblast growth factor were investigated using immunohistochemistry for astrocytoma from 82 patients and 11 normal human tissues. The expression of vascular endothelial growth factor and basic fibroblast growth factor positively correlate with the pathological grade of astrocytoma, microvessel density numbers and brain oedema, which may be responsible for the increased tumour neovascularization and peritumoural brain oedema. The results support the idea that inhibiting vascular endothelial growth factor and basic fibroblast growth factor are useful for the treatment of human astrocytoma and to improve patient's clinical outcomes and prognosis.

    Namie, Hiromune; Morishita, Hisashi

    The authors focused on the development of an indoor positioning system which is easy to use, portable and available for everyone. This system is capable of providing the correct position anywhere indoors, including onboard ships, and was invented in order to evaluate the availability of GPS indoors. Although the performance of GPS is superior outdoors, there has been considerable research regarding indoor GPS involving sensitive GPS, pseudolites (GPS pseudo satellite), RFID (Radio Frequency IDentification) tags, and wireless LAN .However, the positioning rate and the precision are not high enough for general use, which is the reason why these technologies have not yet spread to personal navigation systems. In this regard, the authors attempted to implement an indoor positioning system using cellular phones with built-in GPS and infrared light data communication functionality, which are widely used in Japan. GPS is becoming increasingly popular, where GPGGS sentences of the NMEA outputted from the GPS receiver provide spatiotemporal information including latitude, longitude, altitude, and time or ECEF xyz coordinates. As GPS applications grow rapidly, spatiotemporal data becomes key to the ubiquitous outdoor and indoor seamless positioning services at least for the entire area of Japan, as well as to becoming familiar with satellite positioning systems (e.g. GPS). Furthermore, the authors are also working on the idea of using PDAs (Personal Digital Assistants), as cellular phones with built-in GPS and PDA functionality are also becoming increasingly popular.

    In this paper, we propose a real-time algorithm for estimating the relative position of a person with respect to a robot (camera) using a monocular camera. The algorithm detects the head and shoulder regions of a person using HOG (Histogram of Oriented Gradient) feature vectors and an SVM (Support Vector Machine) classifier. The size and location of the detected area are used for calculating the relative distance and angle between the person and the camera on a robot. To increase the speed of the algorithm, we use a GPU and NVIDIA's CUDA library; the resulting algorithm speed is ∼ 15 Hz. The accuracy of the algorithm is compared with the output of a SICK laser scanner

    2001-01-01

    To test hypotheses about positive emotion, the authors examined the relationship of positive emotional expression in women's college pictures to personality, observer ratings, and life outcomes. Consistent with the notion that positive emotions help build personal resources, positive emotional expression correlated with the self-reported personality traits of affiliation, competence, and low negative emotionality across adulthood and predicted changes in competence and negative emotionality. Observers rated women displaying more positive emotion more favorably on several personality dimensions and expected interactions with them to be more rewarding; thus, demonstrating the beneficial social consequences of positive emotions. Finally, positive emotional expression predicted favorable outcomes in marriage and personal well-being up to 30 years later. Controlling for physical attractiveness and social desirability had little impact on these findings.

    The Big Seven model of personality includes five dimensions similar to the Big Five model as well as two evaluative dimensions—Positive Valence (PV) and Negative Valence (NV)—which reflect extremely positive and negative person descriptors, respectively. Recent theory and research have suggested that PV and NV predict significant variance in personality disorder (PD) above that predicted by the Big Five, but firm conclusions have not been possible because previous studies have been limited to only single measures of PV, NV, and the Big Five traits. In the present study, we replicated and extended previous findings using three markers of all key constructs—including PV, NV, and the Big Five—in a diverse sample of 338 undergraduates. Results of hierarchical multiple regression analyses revealed that PV incrementally predicted Narcissistic and Histrionic PDs above the Big Five and that NV nonspecifically incremented the prediction of most PDs. Implications for dimensional models of personality pathology are discussed. PsycINFO Database Record (c) 2010 APA, all rights reserved.

  19. Feature interpretability and the positions of 2nd person possessives in Brazilian Portuguese

    Full Text Available Interpretability and valuation of φ-features (Chomsky, 2001; Pesetsky and Torrego, 2007 have played a central role in the investigation of language universals. With regard to that, in standard Brazilian Portuguese (BP, as well as in other Romance languages, possessives have uninterpretable number features, which are valued via nominal agreement. However, dialects of BP, especially the one spoken in Minas Gerais, have shown that 2nd person possessives, in postnominal position, do not have number agreement with the noun. In order to account for these facts, I will argue that, in this grammar, number features on 2nd person possessives are reanalyzed as being: (i associated with the person (rather than the noun and (ii interpretable. From the first postulation, ‘seu’ is expected to be the possessive for 2nd person singular, and ‘seus’ for 2nd person plural. From the second postulation, no number concord is expected to be triggered on the possessive. In addition, based on Danon (2011 and Norris (2014, I will argue that cardinals divide BP DPs into two domains in that phrases located above NumP are marked with the plural morpheme, while phrases below it are unmarked. In this sense, because prenominal possessives precede cardinals (NumP, they must be marked with the plural morpheme for nominal agreement; whereas postnominal possessives, which follow NumP, must be unmarked. Free from the plural marking associated with nominal agreement, postnominal 2nd person possessives favor the reanalysis of the morpheme ‘-s’ as indicating the number associated with person features.

    The purpose of this research was to assess the impact of nonstereotypical, positive media portrayals of obese persons on biased attitudes, as well as propose a change in media practices that could reduce public weight bias and consequent negative health outcomes for those who experience weight stigma. Two online experiments were conducted in which participants viewed either a stigmatizing or a positive photograph of an obese model. In Experiment 1 (N = 146), participants viewed a photograph of either a Caucasian or African American obese woman; in Experiment 2 (N = 145), participants viewed either a Caucasian male or female obese model. Multiple linear regression models were used to analyze outcomes for social distance attitudes toward the obese models depicted in the images, in addition to other negative attitudes and image preferences. Participants who viewed the stigmatizing images endorsed stronger social distance attitudes and more negative attitudes toward obese persons than participants who viewed the positive images, and there was a stronger preference for the positive images than the stigmatizing images. These results were consistent regardless of the race or gender of the obese model pictured. The findings indicate that more positive media portrayals of obese individuals may help reduce weight stigma and its associated negative health outcomes.

    Full Text Available The aim of the paper is to assess academic experiential learning in relation to academic lectures' perceived personal and professional growth. Sixteen PhD students (age ranged between 23 and 46, 10 male, 6 females participated in an introduction to expressive art therapy. Qualitative methods according to phenomenological methodology was used. At the beginning and end of the 48-h course they were asked to draw themselves, and explain the differences between the two drawings. In addition participants were semi-structured interviewed about the course and its personal and professional aspects at the end of the course. The main themes were the carousal of emotional experience, the use of art means for growth, and, professional growth. Findings revealed a perceived growth in terms of family relationships, inter—personal skills, and professional role performance.

  2. Does personality play a role in continuous positive airway pressure compliance?

    Continuous positive airway pressure (CPAP adherence is low among individuals with obstructive sleep apnoea. Type D personality and high scores on the depression and hypochondriasis scales on the Minnesota Multiphasic Personality Inventory (MMPI have been identified as factors contributing to non-compliance with CPAP. Further research into personality type may assist in understanding why some people adhere to CPAP, while others fail. Obstructive sleep apnoea (OSA is a condition characterised by repetitive, intermittent partial or complete collapse/obstruction of the upper airway during sleep. Continuous positive airway pressure (CPAP is highly efficacious in treating OSA but its effectiveness is limited due to suboptimal acceptance and adherence rates, with as many as 50% of OSA patients discontinuing CPAP treatment within the first year. Until recently, research has focused on examining mechanistic and demographic factors that could explain nonadherence (e.g. age, sex, race and education level with limited applicability in a prospective or clinical manner. More recent research has focused on personality factors or types of patients with OSA who comply and do not comply with CPAP adherence in an attempt to enhance the accuracy of predicting treatment compliance. Type D personality has been found to be prevalent in one third of patients with OSA. The presence of Type D personality increases noncompliance and poor treatment outcomes due to negative affectivity, social inhibition, unhealthy lifestyle, and a reluctance to consult and/or follow medical advice. Conversely, individuals who are more likely to adhere to CPAP treatment tend to have a high internal locus of control and high self-efficacy, self-refer for treatment, and have active coping skills. By assessing personality and coping skills, the clinician may gain insight into the likelihood of a patient’s adherence to treatment. If the patient displays potential risk factors for CPAP noncompliance, the

    This study is part of the Amsterdam Growth and Health Longitudinal Study, which was undertaken to assess the long-term interrelationships between cumulative frequency of geographic relocation (CFGR) and the development of personality characteristics (i.e., Inadequacy, Rigidity, Social Inadequacy, Dominance, Self-sufficiency, Self-esteem, and Hostility). We found that participants who had more mobility experiences had lower consistency in their personality characteristics (the exception being Rigidity). Residential mobility from different life stages was positively associated with the continuity and change of Inadequacy and Dominance. In addition, young adults with higher Rigidity personality experienced fewer geographic moves during the transition from young adulthood to mid-life. Our study provides evidence that CFGR in different life stages may be associated with the development of personality characteristics from young adulthood to mid-life in different ways. Increased awareness of the potential interrelationships between frequent geographic relocation and personality development may have positive consequences for adult psychological health. © 2011 American Orthopsychiatric Association.

    Chronotype and sport participation have been found to relate to positive personality-trait-like individual differences (PTLID). To date, research has focused exclusively on the morningness-eveningness dimension of chronotype, and little is known about the relationship between chronotype and various characteristics of sport participation (e.g. training time). This investigation had three primary objectives: (1) to extend the current evidence base by exploring how sport participation and PTLID relate to chronotype amplitude, (2) to explore how chronotype (morningness-eveningness and amplitude) relates to various characteristics of sport training and competition, and (3) to explore the independent and interrelated contribution of sport participation and chronotype to PTLID. The sample included 976 non-athletes (493 women and 483 men) and 974 athletes (478 women and 496 men). Participants completed a battery of questionnaires targeting sport participation characteristics, six positive PTLID (hope, optimism, perseverance, resilience, self-efficacy and trait emotional intelligence) and chronotype dimensions. Results showed that morningness-eveningness was negatively related to positive PTLID but was unrelated to sport participation. Greater diurnal fluctuations (amplitude dimension) were associated with lower positive PTLID values, lower sport participation, and shorter training durations. Positive PTLID were also associated with better sleep quality and a shorter sleep duration. Chronotype (morningness-eveningness and amplitude) and sport participation had independent associations with PTLID. These findings suggest that changes in sport participation and activity times might be a useful approach to developing positive PTLID.

    Some researchers suggest that borderline personality disorder (BPD) is characterized by elevated negative emotion; others argue that BPD involves both reduced positive and increased negative emotion. This study characterizes the emotional experiences of individuals with BPD symptoms in a combined university and community sample. Participants (N = 150) completed a clinical interview assessing BPD symptoms and self-report measures of positive and negative emotion. A subset (n = 106) completed a measure of emotion daily for 2 weeks. Pearson's correlations and multilevel modeling were used to examine the cross-sectional and longitudinal relationships between BPD symptoms and emotions. BPD symptoms were robustly related to increased negative emotion; this relationship remained after accounting for positive emotion. BPD symptoms were weakly related to decreased positive emotion; this relationship was no longer significant after accounting for negative emotion. BPD symptoms predicted higher levels of negative and not positive emotion over 14 days. These patterns held for subscales assessing intensity, frequency, and duration of negative and positive emotions. Findings suggest that individuals with BPD features are chiefly distinguished by elevated negative emotional experience. © 2016 Wiley Periodicals, Inc.

    Keen-Rocha, Linda S.

    The nature of this study was to explore changes in beliefs and lay a foundation for focusing on more specific features of reasoning related to personal epistemological and NOS beliefs in light of specific science laboratory instructional pedagogical practices (e.g., pre- and post-laboratory activities, laboratory work) for future research. This research employed a mixed methodology, foregrounding qualitative data. The total population consisted of 56 students enrolled in several sections of a general chemistry laboratory course, with the qualitative analysis focusing on the in-depth interviews. A quantitative NOS and epistemological beliefs measure was administered pre- and post-instruction. These measures were triangulated with pre-post interviews to assure the rigor of the descriptions generated. Although little quantitative change in NOS was observed from the pre-post NSKS assessment a more noticeable qualitative change was reflected by the participants during their final interviews. The NSKS results: the mean gain scores for the overall score and all dimensions, except for amoral were found to be significant at p ≤ .05. However there was a more moderate change in the populations' broader epistemological beliefs (EBAPS) which was supported during the final interviews. The EBAPS results: the mean gain scores for the overall score and all dimensions, except for the source of ability to learn were found to be significant at p ≤ .05. The participants' identified the laboratory work as the most effective instructional feature followed by the post-laboratory activities. The pre-laboratory was identified as being the least effective feature. The participants suggested the laboratory work offered real-life experiences, group discussions, and teamwork which added understanding and meaning to their learning. The post-laboratory was viewed as necessary in tying all the information together and being able to see the bigger picture. What one cannot infer at this point is

    Donated tissues can save lives of critically burned patients and those needing a heart valve replacement. Tissues enhance the lives of a million recipients annually through transplants of corneas, bones, tendons, and vein grafts. Unfortunately, the need for some tissues exceeds their availability. The goal of the quantitative component of this mixed methods study was to identify the grief, posttraumatic stress, personal growth, and ongoing attachment response of tissue donors' family members during a 2-year period. Simultaneous mixed methods design. The sample for this study consisted of 52 tissue donors' family members, mostly widows (83%). Data were collected for 2 years to test changes in grief, posttraumatic stress, panic behavior, personal growth, and ongoing attachment. The bereaved participants experienced significantly fewer grief reactions, less posttraumatic stress, and greater personal growth. There was no significant difference in the ongoing attachment to their deceased loved ones. The results of this study may reinforce the positive meaning that tissue donors' family members can find in tissue donation. Findings also demonstrate that the bereavement process corroborates contemporary bereavement and attachment theories. Health professionals are encouraged to seek donations with less worry that tissue donors' family members will experience adverse outcomes during bereavement.

    Neuroticism and extraversion are multifaceted affective-laden personality traits that have been associated with major depressive disorder (MDD). Research and theory have argued that extraversion, and particularly its facet positive emotionality, is specific to MDD, while neuroticism is common across internalizing disorders. Converging evidence has suggested that MDD is associated with reduced engagement with emotional stimuli, but it remains unclear whether either extraversion, neuroticism, or both modulate reactivity to emotional cues. The late positive potential (LPP) is an event-related brain potential that is uniquely suited to assess engagement with emotional stimuli because it reflects sustained attention toward emotional content. The current study examined the LPP in relation to personality traits that may confer risk for depression by examining the relationship between the LPP and both neuroticism and extraversion in never-depressed adolescent girls. Specifically, 550 girls aged 13.5-15.5 with no lifetime history of depression completed an emotional picture-viewing task, and the LPP was measured in response to neutral, pleasant, and unpleasant pictures. Personality traits were gathered via self- and informant report. Results indicated that high extraversion was associated with a potentiated LPP to emotional pictures-and this effect was accounted for by positive emotionality in particular. In contrast, there was no association between the LPP and neuroticism or its facets. The present study is one of the first to demonstrate that extraversion is associated with variation in neural indices of emotional picture processing, similar to what has been observed among individuals with depression and at high risk for depression. © 2015 Society for Psychophysiological Research.

    Encounters with strangers bear potential for social conflict and stress, but also allow the formation of alliances. First impressions of other people play a critical role in the formation of alliances, since they provide a learned base to infer the other's future social attitude. Stress can facilitate emotional memories but it is unknown whether stress strengthens our memory for newly acquired impressions of other people's personality traits. To answer this question, we subjected 60 students (37 females, 23 males) to an impression-formation task, viewing portraits together with brief positive vs. negative behavior descriptions, followed by a 3-min cold pressor stress test or a non-stressful control procedure. The next day, novel and old portraits were paired with single trait adjectives, the old portraits with a trait adjective matching the previous day's behavior description. After a filler task, portraits were presented again and subjects were asked to recall the trait adjective. Cued recall was higher for old (previously implied) than the novel portraits' trait adjectives, indicating validity of the applied test procedures. Overall, recall rate of implied trait adjectives did not differ between the stress and the control group. However, while the control group showed a better memory performance for others' implied negative personality traits, the stress group showed enhanced recall for others' implied positive personality traits. This result indicates that post-learning stress affects consolidation of first impressions in a valence-specific manner. We propose that the stress-induced strengthening of memory of others' positive traits forms an important cue for the formation of alliances in stressful conditions.

    The relation between overly positive self-evaluations and psychological adjustment was examined. Three studies, two based on longitudinal data and another on laboratory data, contrasted self-descriptions of personality with observer ratings (trained examiners or friends) to index self-enhancement. In the longitudinal studies, self-enhancement was associated with poor social skills and psychological maladjustment 5 years before and 5 years after the assessment of self-enhancement. In the laboratory study, individuals who exhibited a tendency to self-enhance displayed behaviors, independently judged, that seemed detrimental to positive social interaction. These results indicate there are negative short-term and long-term consequences for individuals who self-enhance and, contrary to some prior formulations, imply that accurate appraisals of self and of the social environment may be essential elements of mental health.

    This study examined self-esteem as mediator in the relations of personal (extraversion, neuroticism) and environmental (maternal, paternal, peer-relationships) variables with domains of positive psychological functioning (PPF) in adolescence (Satisfaction with life, Mastery, Vigor, Social Interest, Social Cheerfulness). We compared one-sided and multidimensional models using a sample of 1193 high school students (592 males and 601 females). We examined variations in adolescent PPF as a function of parenting styles via independent examination of maternal and paternal bonding. Results supported the multidimensional models, which indicated direct effects of personality traits, maternal care and peer relationships, as well as indirect effects, mediated by self-esteem, of all predictors on most PPF dimensions. Overall, our study provided a broader picture of personal and environmental predictors on different dimensions of PPF, which supported the mediating role of self-esteem and emphasized the importance of considering multidimensional models to characterize PPF in adolescents.

    Particle Swarm Optimization (PSO) is a popular algorithm which is widely investigated and well implemented in many areas. However, the canonical PSO does not perform well in population diversity maintenance so that usually leads to a premature convergence or local optima. To address this issue, we propose a variant of PSO named Grouping PSO with Personal- Best-Position (Pbest) Guidance (GPSO-PG) which maintains the population diversity by preserving the diversity of exemplars. On one hand, we adopt uniform random allocation strategy to assign particles into different groups and in each group the losers will learn from the winner. On the other hand, we employ personal historical best position of each particle in social learning rather than the current global best particle. In this way, the exemplars diversity increases and the effect from the global best particle is eliminated. We test the proposed algorithm to the benchmarks in CEC 2008 and CEC 2010, which concern the large scale optimization problems (LSOPs). By comparing several current peer algorithms, GPSO-PG exhibits a competitive performance to maintain population diversity and obtains a satisfactory performance to the problems.

    Driving behaviors play an important role in accident involvement. Concretely speaking, aberrant driving behaviors would cause more accidents, and oppositely positive driving behaviors would promote to build safety traffic environment. The main goals of this study were to explore the positive driving behavior and its relationship with personality in a Chinese sample. A total of 421 licensed drivers (286 male and 135 female) from Beijing, China completed the Positive Driver Behavior Scale (PDBS), the Driver Behavior Questionnaire (DBQ), the Dula Dangerous Driving Index (DDDI) and the Big Five Inventory (BFI) on a voluntary and anonymous basis. The results showed that the Chinese version of the PDBS has both reliability and validity and that the PDBS was significantly correlated with the BFI. Specifically, the PDBS was negatively correlated with neuroticism (r = -0.38) and positively correlated with extraversion, agreeableness, conscientiousness and openness to experience (the correlation coefficient ranged from 0.36 to 0.55). In contrast with previous research, age was negatively correlated with the PDBS (r = -0.38) in our sample, which may have resulted from less driving experience or a lack of available cognitive resources.

Specifically, the PDBS was negatively correlated with neuroticism (r = -0.38 and positively correlated with extraversion, agreeableness, conscientiousness and openness to experience (the correlation coefficient ranged from 0.36 to 0.55. In contrast with previous research, age was negatively correlated with the PDBS (r = -0.38 in our sample, which may have resulted from less driving experience or a lack of available cognitive resources.

    Driving behaviors play an important role in accident involvement. Concretely speaking, aberrant driving behaviors would cause more accidents, and oppositely positive driving behaviors would promote to build safety traffic environment. The main goals of this study were to explore the positive driving behavior and its relationship with personality in a Chinese sample. A total of 421 licensed drivers (286 male and 135 female) from Beijing, China completed the Positive Driver Behavior Scale (PDBS), the Driver Behavior Questionnaire (DBQ), the Dula Dangerous Driving Index (DDDI) and the Big Five Inventory (BFI) on a voluntary and anonymous basis. The results showed that the Chinese version of the PDBS has both reliability and validity and that the PDBS was significantly correlated with the BFI.

    Full Text Available The 2011 Census in the Republic of Serbia introduced, for the first time questions about difficulties in functioning, following the Recommendations from the Washington Group on Disability Statistics. Since there are no stable and continuous sources on the position of persons with disabilities in Serbia, the Census results may be used as a relevant source on disability measurement. Of course, due to the main goal of census disability measurement, and that is a general identification of disability in population, these results should be employed with certain reservations and carefully, especially because of some methodological specification in approaching disability. The main use of census data on disability should be found in evaluating the "equality of opportunity" in relevant areas, such as economic activity (labour and employment, education, living sources, etc. and this is to be achieved mainly through comparison between the values in the general population and population with disabilities. Having done that, we were able to conclude on visible inequality of opportunities between the general and population with disabilities. These discrapancies are indeed evident first in the area of education-especially in accessing elementary education, where the percentage of persons with disabilities that never attended school is extremely high (12.2% v. 2.68% in general population. The unfavourable status of persons with disabilities in the context of education continues in almost all levels of education. An even more obvious inequality of opportunity is present in the area of economic activity, where the prevalence of inactive persons with disability is very high - almost 90%. Having gone through all the age categories, what becomes abvious is a significantly lower activity among all age groups in comparison to the same groups in general population. However, the main goal of this article was to detect the discrapancies existing between the position of

    2014-01-01

    The aim of the study is to explore how personal and contextual experiences throughout the life course are recollected as having influenced the development of stigma-handling strategies among people associated with disability and stigma. The article describes the development of stigma handling among ageing persons of restricted growth in order to avert negative effects, develop resilience, strengthen the self and support a positive identity. Qualitative retrospective interviews were conducted with ten persons - seven women and three men aged between 45 and 65 years - of short stature. Their narratives are analysed from a life-course perspective and the results presented under two main themes: the development of strategies during different stages of life, and the use of general non-stage-bound strategies. The study shows how stigma-handling has evolved from childhood to become, by adult years, refined, contextualised strategies demonstrating human resilience. The analysis documents the impact of human agency on personal lives and the subjects' efforts and strengths in handling adversity. The results demonstrate how the "insider perspective" reveals the individual's resources, resilience and strategies and provides an important perspective for the rehabilitation setting. Implications for Rehabilitation The study document human agency, resilience and strength in a life course perspective among people of restricted growth faced with stigmatization. The efforts and stigma handling strategies developed during the life course, such as withdrawal, humour, ignoring and positive thinking, are important tools to be recognized with relevance for other patient groups. The "insider perspective" revealing the potentialities and strength of human agency and resilience, should be further explored within the field of rehabilitation.

  7. Negative evaluation bias for positive self-referential information in borderline personality disorder.

    Directory of Open Access Journals (Sweden)

    Dorina Winter

    Full Text Available Previous research has suggested that patients meeting criteria for borderline personality disorder (BPD display altered self-related information processing. However, experimental studies on dysfunctional self-referential information processing in BPD are rare. In this study, BPD patients (N = 30 and healthy control participants (N = 30 judged positive, neutral, and negative words in terms of emotional valence. Referential processing was manipulated by a preceding self-referential pronoun, an other-referential pronoun, or no referential context. Subsequently, patients and participants completed a free recall and recognition task. BPD patients judged positive and neutral words as more negative than healthy control participants when the words had self-reference or no reference. In BPD patients, these biases were significantly correlated with self-reported attributional style, particularly for negative events, but unrelated to measures of depressive mood. However, BPD patients did not differ from healthy control participants in a subsequent free recall task and a recognition task. Our findings point to a negative evaluation bias for positive, self-referential information in BPD. This bias did not affect the storage of information in memory, but may be related to self-attributions of negative events in everyday life in BPD.

    Tamoxifen, an endocrine therapy drug used to treat breast cancer, is designed to interrupt estrogen signaling by blocking the estrogen receptor (ER). However, many ER-positive patients are low reactive or resistant to tamoxifen. Metformin is a widely used anti-diabetic drug with noteworthy anti-cancer effects. We investigated whether metformin has the additive effects with tamoxifen in ER-positive breast cancer therapy. The efficacy of metformin alone and in combination with tamoxifen against ER-positive breast cancer was analyzed by cell survival, DNA replication activity, plate colony formation, soft-agar, flow cytometry, immunohistochemistry, and nude mice model assays. The involved signaling pathways were detected by western blot assay. When metformin was combined with tamoxifen, the concentration of tamoxifen required for growth inhibition was substantially reduced. Moreover, metformin enhanced tamoxifen-mediated inhibition of proliferation, DNA replication activity, colony formation, soft-agar colony formation, and induction of apoptosis in ER-positive breast cancer cells. In addition, these tamoxifen-induced effects that were enhanced by metformin may be involved in the bax/bcl-2 apoptotic pathway and the AMPK/mTOR/p70S6 growth pathway. Finally, two-drug combination therapy significantly inhibited tumor growth in vivo. The present work shows that metformin and tamoxifen additively inhibited the growth and augmented the apoptosis of ER-positive breast cancer cells. It provides leads for future research on this drug combination for the treatment of ER-positive breast cancer

    Full Text Available Background: Posttraumatic growth (PTG is conceptualized as a positive transformation resulting from coping with and processing traumatic life events. This study examined the contributory roles of personality traits, posttraumatic stress (PTS severity and their interactions on PTG and its domains, as assessed with the Posttraumatic Growth Inventory Turkish form (PTGI-T. The study also examined the differences in PTG domains between survivors of accidents, natural disasters and unexpected loss of a loved one. Methods: The Basic Personality Traits Inventory, Posttraumatic Diagnostic Scale, and PTGI-T were administered to a large stratified cluster community sample of 969 Turkish adults in their home settings. Results: The results showed that conscientiousness, agreeableness, and openness to experience significantly related to the total PTG and most of the domains. The effects of extraversion, neuroticism and openness to experience were moderated by the PTS severity for some domains. PTG in relating to others and appreciation of life domains was lower for the bereaved group. Conclusion: Further research should examine the mediating role of coping between personality and PTG using a longitudinal design.

    Exercise improves sleep quality, yet people with untreated obstructive sleep apnea (OSA) may engage in less physical activity (PA) due to fatigue and daytime sleepiness. We examined changes in PA and sleep quality before and after treatment with continuous positive airway pressure (CPAP) in OSA patients. In this prospective longitudinal study, persons with a primary diagnosis of OSA were enrolled at a community-based hospital in New York City. At 3 time intervals pre- and post-CPAP (3-8 months), we measured sleep quality using validated questionnaires, perceived PA using the International Physical Activity Questionnaire (IPAQ), and actual PA using pedometer steps per day. We sought to investigate how CPAP use and changes in sleep quality impacted the number of steps taken, as recorded in pedometer steps. In total, 62 patients were enrolled in the study from March 2012 to July 2014. In all, patients averaged 53 years of age, and 26 patients (42%) were female. Among all participants, 86% of persons had moderate to severe sleep apnea (AHI ≥15). Approximately 73% of participants were compliant with CPAP use. Poor sleep quality correlated with lower actual PA (P = .004) at baseline. At 3 and 7 months, there was significant improvement in sleep quality (Δ -2.63 ± 3.4 and Δ -3.5 ± 3.8; P improvement in sleep quality and actual PA.

  13. Activity in ventromedial prefrontal cortex during self-related processing: positive subjective value or personal significance?

    Science.gov (United States)

    Kim, Kyungmi; Johnson, Marcia K

    2015-04-01

    Well-being and subjective experience of a coherent world depend on our sense of 'self' and relations between the self and the environment (e.g. people, objects and ideas). The ventromedial prefrontal cortex (vMPFC) is involved in self-related processing, and disrupted vMPFC activity is associated with disruptions of emotional/social functioning (e.g. depression and autism). Clarifying precise function(s) of vMPFC in self-related processing is an area of active investigation. In this study, we sought to more specifically characterize the function of vMPFC in self-related processing, focusing on two alternative accounts: (i) assignment of positive subjective value to self-related information and (ii) assignment of personal significance to self-related information. During functional magnetic resonance imaging (fMRI), participants imagined owning objects associated with either their perceived ingroup or outgroup. We found that for ingroup-associated objects, vMPFC showed greater activity for objects with increased than decreased post-ownership preference. In contrast, for outgroup-associated objects, vMPFC showed greater activity for objects with decreased than increased post-ownership preference. Our findings support the idea that the function of vMPFC in self-related processing may not be to represent/evaluate the 'positivity' or absolute preference of self-related information but to assign personal significance to it based on its meaning/function for the self. © The Author (2014).

    2013-01-01

    The purpose of this study is to examine the impact of strategic position on the ability of an entrepreneurial firm to successfully develop and deploy electronic personal health records technology within the US healthcare industry. This study uses an in-depth longitudinal case study methodology. The study contributes by juxtaposing a longitudinal view of how the focal firm proposed and acted on different strategic positions in an attempt to achieve development and deployment success. In doing so, the study also elaborates on Porter's recognition that firms need to make trade-offs when choosing a strategic position, as the purposeful limitation of service offerings can protect against the degradation of existing value creating activities. The authors' study highlights the enormous challenge of facilitating the adoption and diffusion of technology enabled interventions in the US healthcare ecosystem. Future research that combines both interdisciplinary and multi-level investigation and analysis is sorely needed to develop a more sophisticated understanding of the phenomenon and to encourage the development and deployment of useful technology enabled interventions within the US healthcare industry. While the fragmented nature of the healthcare industry provides opportunities for entrepreneurial firms, such complexity within the ecosystem should not be underestimated as a reason for concern for small firms. Total economic burden due to chronic diseases and other healthcare-related expenses is massive for the USA. Consequently, prevention and early detection of future disease states has become a core component of the current healthcare reform debate. EPHRs are considered one core component of a broader healthcare strategy to improve health outcomes and lower costs. By deepening our understanding of how best to develop and deploy such interventions, society will surely benefit. The longitudinal nature of the authors' study provides a unique opportunity to understand the

    2017-10-01

    The aim of this study was to explore experiences of positive growth in long-term childhood cancer survivors, from their perspective. Fifteen long-term survivors of childhood cancer provided descriptions of their experiences. Data were collected through face-to-face interviews and the analysis was based on Giorgi's phenomenological research method. The analysis of positive growth experienced by long-term childhood cancer survivors revealed three themes: self-directed life, normalcy in life, and inner maturity. Long-term survivors defined positive growth as a successful transition to a self-satisfactory life based on motivation acquired through their cancer experience and on subjective goal-setting, as well as becoming cancer-free and living a normal life within society. They seemed to have acquired optimistic, flexible, active attitudes toward life while demonstrating profound gratefulness and consideration of people around them, as well as prudent approaches to health. The findings of this study verified that long-term survivors of childhood cancer have grown positively due to their negative past experience. We expect these findings to contribute to the development of programs that promote positive growth in long-term childhood cancer survivors. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2014-12-01

    Chronic infections and liver diseases may influence the growth and development of children by leading to malnutrition. In this study, demographic characteristics, anthropometric measurements and laboratory findings for children with hepatitis B positivity were analyzed. A total of 43 cases were admitted to our clinic between January 2012 and February 2013 and detected to have HBsAg positivity. Malnutrition was detected in 11 cases (25.6%) and obesity in three cases (6.9%). Aspartate aminotransferase (AST) levels were significantly higher in malnourished patients compared to those without malnutrition. The weight to height was significantly higher in patients with positive HBeAg compared to children with negative HBeAg. We found that the weight standard deviation scores (SDS) ratios dropped as alanine aminotransferase (ALT) and AST levels increased and height SDS ratios decreased. In addition, body mass index (BMI) decreased as AST and alpha feto protein (AFP) values increased. While a significant relationship was not detected between insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) and ALT, a significantly negative correlation was detected between IGFBP-3 and IGF-1 and AST. We found a malnutrition rate of 25.6% in children with HBsAg positivity. We also found that weight and height SDS rates decreased as ALT and AST levels increased. In addition, we detected that BMI decreased as AST and AFP values increased. We consider that hepatic inflammation is the factor that affects growth. Monitoring of growth and development during follow-up of children who are detected to have HBsAg positivity would be beneficial to determine the mechanism and causes of growth retardation.

Evaluative character of the considered aggravating circumstance doesn’t allow to develop clear criteria for identifying the leaders of the criminal environment. Basing on the theory provisions and court practice, the authors suggest three criteria. The first criterion is specific actions including: establishment and leadership of the criminal association (criminal organization; coordinating criminal acts; creating sustainable links between different organized groups acting independently; dividing spheres of criminal influence, sharing criminal income and other criminal activities, indicating person’s authority and leadership in a particular area or in a particular sphere of activity. The second is having money, valuables and other property obtained by criminal means, without the person’s direct participation in their acquisition; transferring money, valuables and other property to that person systematically, without legal grounds (unjust enrichment; spending that money, valuables and other property to carry out criminal activities (crimes themselves and conditions of their commission. The third is international criminal ties manifested in committing one of the crimes under Part 1 of Article 210 of the RF Criminal Code, if this crime is transnational in nature; ties with extremist and (or terrorist organizations, as well as corruption ties. The court may use one or several of these criteria.

  1. Facebook Surveillance of Former Romantic Partners: Associations with PostBreakup Recovery and Personal Growth

    Science.gov (United States)

    2012-01-01

    Abstract Previous research has found that continuing offline contact with an ex-romantic partner following a breakup may disrupt emotional recovery. The present study examined whether continuing online contact with an ex-partner through remaining Facebook friends and/or engaging in surveillance of the ex-partner's Facebook page inhibited postbreakup adjustment and growth above and beyond offline contact. Analysis of the data provided by 464 participants revealed that Facebook surveillance was associated with greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth. Participants who remained Facebook friends with the ex-partner, relative to those who did not remain Facebook friends, reported less negative feelings, sexual desire, and longing for the former partner, but lower personal growth. All of these results emerged after controlling for offline contact, personality traits, and characteristics of the former relationship and breakup that tend to predict postbreakup adjustment. Overall, these findings suggest that exposure to an ex-partner through Facebook may obstruct the process of healing and moving on from a past relationship. PMID:22946958

    2015-04-01

    To test the hypotheses that medical students recognized by peers as the most positive social influencers would score (1) high on measures of engaging personality attributes that are conducive to relationship building (empathy, sociability, activity, self-esteem), and (2) low on disengaging personality attributes that are detrimental to interpersonal relationships (loneliness, neuroticism, aggression-hostility, impulsive sensation seeking). The study included 666 Jefferson Medical College students who graduated in 2011-2013. Students used a peer nomination instrument to identify classmates who had a positive influence on their professional and personal development. At matriculation, these students had completed a survey that included the Jefferson Scale of Empathy and Zuckerman-Kuhlman Personality Questionnaire short form and abridged versions of the Rosenberg Self-Esteem Scale and UCLA Loneliness Scale. In multivariate analyses of variance, the method of contrasted groups was used to compare the personality attributes of students nominated most frequently by their peers as positive influencers (top influencers [top 25% in their class distribution], n = 176) with those of students nominated least frequently (bottom influencers [bottom 25%], n = 171). The top influencers scored significantly higher on empathy, sociability, and activity and significantly lower on loneliness compared with the bottom influencers. However, the effect size estimates of the differences were moderate at best. The research hypotheses were partially confirmed. Positive social influencers appear to possess personality attributes conducive to relationship building, which is an important feature of effective leadership. The findings have implications for identifying and training potential leaders in medicine.

    Maltreated children are a vulnerable population, yet many of these youth follow positive developmental pathways. The primary aim was to identify social skills growth trajectories among at-risk youth to understand processes underlying resilience. Nationally representative, longitudinal data from 1,179 families investigated for child maltreatment (M age  = 12.75) were obtained from the National Survey of Child and Adolescent Well-Being. Four trajectories were identified-stress-resistant, emergent resilience, breakdown, and unresponsive-maladaptive. Protective resources from multiple levels of the youth ecology (individual, family, school, and social service) predicted positive growth social skills trajectories.

    Full Text Available Introduction & Objective: Many factors such as retirement, work disability, being isolated from the society, physical illness… affect the general health of the aged , one factor among many, is the role of psychological variables. The purpose of this study has been the investigation of the effect of positive and negative perfectionism and type D personality on general health of the aged. Materials & Methods: In this descriptive-correlational study, 80 subjects (47 males and 33 females were selected through available sampling method among the aged in nursing homes in Hamadan and Malayer. Then the positive and negative perfectionism questionnaire of Terry- Short et al, that of type D personality and Goldberg and Hiller's general health questionnaire were administered to them. Results: Positive perfectionism (r=-0.30 and type D personality (r=0.32 had significant correlations with general health. Multiple regression analysis also revealed that positive perfectionism and type D could explain at least 49 percent of the variance of general health. The females’ mean was higher than that of males concerning the variables of depression-anxiety, speech inhibition and irritability and in positive perfectionism, general health and social function variables the males’ mean was higher than that of females. Conclusion: Creating optimistic attitudes and enhancing social functions, positive perfectionism may cause the mental disorder to be decreased in old age and type D personality; however, positive perfectionism makes the aged apt to physical illness and mental disorder.

    Positive mental health, rather than just the absence of mental illness, is rarely investigated among the internally displaced persons (IDPs) affected by violent conflict in low-income countries. The purpose of this study was to investigate a model that could explain the interrelationship between factors contributing to positive mental health in displaced populations. In a longitudinal study we examine poverty, exposure to traumatic events and the change of material well-being after one year. We collected data in two consecutive years (2005 and 2006) from a community-based sample of IDPs in Ambon, Indonesia, through face-to-face structured interviews with consenting adults. Participants of this study were IDPs lived in Ambon during the violent conflict period. We interviewed 471 IDPs in the first year and reinterviewed 399 (85%) of the same subjects in the second year. The IDPs possessed good sense of coherence and subjective well-being. Our final model, which was generated by the use of structural equation modeling, fits the data well (χ(2) = 52.51, df = 45, p = .21, CFI = .99, RMSEA = .019). Exposure to violent conflict had a negative impact on IDPs' mental health initially and better economic conditions improved it (r = -.30 and .29 respectively). Mental health status one year previously was a strong predictor of future mental health, followed by individual economic growth in the past year (r = .43 and .29 respectively). On a group level the IDPs were resilient and adaptive to survive in adverse living conditions after devastating violent conflict, and the economic improvement contributed to it.

    2010-01-01

    To better understand quantity and quality of divorced father contact, a weighted county sample of 230 divorced fathers with a child aged 4-11 years was employed to test whether fathers' antisocial personality (ASP) moderated effects of monthly contact with children in predicting children's observed noncompliance. Eighteen-month latent growth models obtained significant individual differences in levels of noncompliance and growth rates. ASP significantly moderated beneficial impact of fathers' monthly contact. Fathers' observed parenting practices significantly predicted noncompliance levels but not growth. Parenting did not account for the effect of Contact x ASP, suggesting both environmental and potentially genetic influences on child adjustment. Findings were robust across boys and girls and age levels. Implications for preventive intervention are discussed.

  8. Landscape urbanization and economic growth in China: positive feedbacks and sustainability dilemmas.

    Bai, Xuemei; Chen, Jing; Shi, Peijun

    2012-01-03

    Accelerating urbanization has been viewed as an important instrument for economic development and reducing regional income disparity in some developing countries, including China. Recent studies (Bloom et al. 2008) indicate that demographic urbanization level has no causal effect on economic growth. However, due to the varying and changing definition of urban population, the use of demographic indicators as a sole representing indicator for urbanization might be misleading. Here, we re-examine the causal relationship between urbanization and economic growth in Chinese cities and provinces in recent decades, using built-up areas as a landscape urbanization indicator. Our analysis shows that (1) larger cities, both in terms of population size and built-up area, and richer cities tend to gain more income, have larger built-up area expansion, and attract more population, than poorer cities or smaller cities; and (2) that there is a long-term bidirectional causality between urban built-up area expansion and GDP per capita at both city and provincial level, and a short-term bidirectional causality at provincial level, revealing a positive feedback between landscape urbanization and urban and regional economic growth in China. Our results suggest that urbanization, if measured by a landscape indicator, does have causal effect on economic growth in China, both within the city and with spillover effect to the region, and that urban land expansion is not only the consequences of economic growth in cities, but also drivers of such growth. The results also suggest that under its current economic growth model, it might be difficult for China to control urban expansion without sacrificing economic growth, and China's policy to stop the loss of agricultural land, for food security, might be challenged by its policy to promote economic growth through urbanization.

    Full Text Available Orientation: Personal growth initiative (PGI is an important characteristic of workplace counsellors. Industrial and organisational (I-O psychologists often assist employees with counselling for work-related and personal problems, and therefore PGI is an important research topic for this profession. Research purpose: The purpose of this study was to measure the PGI of I-O psychology students in a higher education institution in South Africa, as well as to explore differences in PGI between demographic groups. Motivation: According to the scope of practice for psychologists, growth and development of employees form part of an I-O psychologist’s responsibilities. PGI is an important characteristic of I-O psychologists as it enables them to efficiently assist employees in growth and development processes. Research design, approach and method: A cross-sectional survey design was used. A purposive non-probability sample (N = 568 of I-O psychology students was taken from a higher education institution in South Africa. A biographical questionnaire and the personal growth initiative scale (PGIS were used as measuring instruments. Main findings: The results indicated that (1 the PGIS is a valid and reliable measure of PGI, (2 PGI is prevalent amongst I-O psychology students and (3 PGI differs between certain demographic groups. Practical implications: The findings of this study will assist in the future development of a training programme for I-O psychology students to equip them with the counselling skills they need to function in a counselling role. Contribution: This study contributes to knowledge regarding the importance of PGI for I-O psychology students. The study will also assist higher education institutes to adapt their training programmes in order to prepare I-O psychology students for their role as counsellors. More knowledge will also be provided with regard to the functioning of the PGIS.

  11. Person-centred positive emotions, object-centred negative emotions: 2-year-olds generalize negative but not positive emotions across individuals.

    Vaish, Amrisha; Grossmann, Tobias; Woodward, Amanda

    2015-09-01

    Prior work suggests that young children do not generalize others' preferences to new individuals. We hypothesized (following Vaish et al., 2008, Psychol. Bull., 134, 383-403) that this may only hold for positive emotions, which inform the child about the person's attitude towards the object but not about the positivity of the object itself. It may not hold for negative emotions, which additionally inform the child about the negativity of the object itself. Two-year-old children saw one individual (the emoter) emoting positively or negatively towards one and neutrally towards a second novel object. When a second individual then requested an object, children generalized the emoter's negative but not her positive emotion to the second individual. Children thus draw different inferences from others' positive versus negative emotions: Whereas they view others' positive emotions as person centred, they may view others' negative emotions as object centred and thus generalizable across people. The results are discussed with relation to the functions and implications of the negativity bias. © 2015 The British Psychological Society.

    2017-06-01

    Full Text Available The purpose of this research is to quantitatively evaluate the growth phase, position, and priorities of the industrialization policy management of the construction industry at firm level. The goal is to integrate quantitative dynamics into the policy-making process for sustainable policy development in future China. This research proposes an integrated framework, including growth management model and industrial policy evaluation method, to identify the challenges of construction industrialization and policy management. The research applies the mixed system method, which includes entropy method and average score method, to analyze the growth stage and major impact indexes targeting 327 survey samples. The empirical results show that the proposed conceptual framework and policy evaluation method could effectively determine the growth position and directions of the construction industrialization. For verification purpose, the study uses the local industry data from Shaanxi Province, China. The calculation results substantiate that the construction industry is in the middle section of the third growth phase. The comparison of the results from statistical methods shows that the local construction industry still needs substantial effort in policy management to improve its sustainable industrialization level. As countermeasures, the policy priorities should concentrate on: (1 enhancing effective cooperation among universities, research institutions and enterprises; (2 improving actions towards technology transfer into productivity; and (3 encouraging market acceptance of construction industrialization. This research complements the existing literature of policy evaluation of construction industrialization. Moreover, it provides theoretical and operational steps on industry policy evaluation and growth management framework, with accurate and ample data analysis on firm-level survey. Researchers and policy makers can use this research for further

    Traditionally, it has been assumed that intellectual development in children with growth hormone deficiency (GHD) is distributed between ranges of a normal population based on the observation that it does not differ substantially from that of children of the same age. Nevertheless, few studies have investigated this assumption. This Spanish Collaborative study was prospectively planned with two main purposes: to study a possible influence of GHD on intelligence quotient (IQ), personality traits and adaptative capacity and to study the evolution of these parameters during substitution therapy with growth hormone (GH). Although the overall intellectual ability of children with GHD is comparable to that of a normal reference population, some areas such the motor-component scale (evaluated by McCarthy test) and performance IQ (evaluated by WISC-R) were below the mean at the beginning of the study, showing significant improvement during therapy. Emotional adjustment (normal at study start) also improved significantly during treatment. Females showed better adjustment capacity before and during GH therapy. Longer studies with an increased number of cases are needed to confirm these effects of GHD and its treatment in children.

    Regarding spatial location positioning, indoor location positioning theories based on wireless communication techniques such as Wi-Fi, beacon, UWB and Bluetooth has widely been developing across the world. These techniques are mainly focusing on spatial location detection of customers using fixed wireless APs and unique Tags in the indoor environment. Besides, since existing detection equipment and techniques using ultrasound or sound etc. to detect buried persons and identify survival status for them cause 2nd damages on the collapsed debris for rescuers. In addition, it might take time to check the buried persons. However, the collapsed disaster sites should consider both outdoor and indoor environments because empty spaces under collapsed debris exists. In order to detect buried persons from the empty spaces, we should collect wireless signals with Wi-Fi from their mobile phone. Basically, the Wi-Fi signal measure 2-D location. However, since the buried persons have Z value with burial depth, we also should collect barometer sensor data from their mobile phones in order to measure Z values according to weather conditions. Specially, for quick accessibility to the disaster area, a drone (UAV; Unmanned Arial Vehicle) system, which is equipped with a wireless detection module, was introduced. Using these framework, this study aims to provide the rescuers with effective rescue information by calculating 3-D location for buried persons based on the wireless and barometer sensor fusion.

    2002-07-01

    To understand soil colonization by a root system, information is needed on the architecture of the root system. In monocotyledons, soil exploration is mainly due to the growth of adventitious primary roots. Primary root emergence in banana was quantified in relation to shoot and corm development. Root emergence kinetics were closely related to the development of aerial organs. Root position at emergence on the corm followed an asymptotic function of corm dry weight, so that the age of each root at a given time could be deduced from its position. Root diameter at emergence was related to the position of the roots on the corm, with younger roots being thicker than older ones. However, root diameters were not constant along a given root, but instead decreased with the distance to the base; roots appear to be conical in their basal and apical parts. Root growth directions at emergence were variable, but a high proportion of the primary roots emerged with a low angle to the horizontal. Further research is needed to evaluate whether these initial trajectories are conserved during root development. Results presented in this study are in good agreement with those reported for other monocotyledons such as maize and rice. They give quantitative information that will facilitate the development of models of root system architecture in banana.

    Sensitivity toward HgCl/sub 2/ of two coagulase-positive Staphylococcus aureus strains has been studied. Strain 15 proved to be over 10 times more resistant to HgCl/sub 2/ in the growth test than strain 31. The former showed also higher rates of endogenous respiration and more actively oxidized glucose in presence of HgCl/sub 2/. Strain 31 grew better in absence of HgCl/sub 2/ but readily underwent inhibition both in the growth and glucose oxidation experiment. Strain 31 was, however, less sensitive to HgCl/sub 2/, as detected by methylene blue reduction in presence of malate and succinate as substrates. Cysteine largely reversed the inhibitory effect of mercuric ions. Experiments with radioactive Hg/sup 203/Cl/sub 2/ did not prove the sensitive strain 31 to bind more mercuric ions than strain 15. 12 references, 4 figures, 4 tables.

  12. Precise Positioning Method for Logistics Tracking Systems Using Personal Handy-Phone System Based on Mahalanobis Distance

    Science.gov (United States)

    Yokoi, Naoaki; Kawahara, Yasuhiro; Hosaka, Hiroshi; Sakata, Kenji

    Focusing on the Personal Handy-phone System (PHS) positioning service used in physical distribution logistics, a positioning error offset method for improving positioning accuracy is invented. A disadvantage of PHS positioning is that measurement errors caused by the fluctuation of radio waves due to buildings around the terminal are large, ranging from several tens to several hundreds of meters. In this study, an error offset method is developed, which learns patterns of positioning results (latitude and longitude) containing errors and the highest signal strength at major logistic points in advance, and matches them with new data measured in actual distribution processes according to the Mahalanobis distance. Then the matching resolution is improved to 1/40 that of the conventional error offset method.

  13. Use of personal computers for Gothic arch tracing: analysis and evaluation of horizontal mandibular positions with edentulous prosthesis.

    Science.gov (United States)

    Watanabe, Y

    1999-11-01

    Determining mandibular position for an edentulous patient raises the question of whether to emphasize centric relation or muscular position. This challenge results from the lack of a convenient procedure for quantifying the horizontal mandibular position, which can be determined by a variety of methods. This study analyzed and evaluated the horizontal mandibular positions produced by different guidance systems. Twenty-six edentulous subjects with no clinical evidence of abnormality of temporomandibular disorder were selected. Horizontal position data for the mandible obtained by gothic arch tracing was loaded into a personal computer by setting the sensor portion of a digitizer into the oral cavity to serve as a miniature lightweight tracing board. By connecting this with a digitizer control circuit set in an extraoral location, each mandibular position was displayed in a distinguishable manner on a computer display in real time, then recorded and analyzed. The gothic arch apex and tapping point varied, depending on body position. In the supine position, the gothic arch apex and the tapping point were close to the mandibular position determined by bilateral manipulation. This system provides effective data concerning mandibular positions for fabrication of dentures.

    Full Text Available ABSTRACT: Objective: To assess the effect of socioeconomic position (SEP in childhood and social mobility on linear growth through adolescence in a population-based cohort. Methods: Children born in Cuiabá-MT, central-western Brazil, were evaluated during 1994 - 1999. They were first assessed during 1999 - 2000 (0 - 5 years and again during 2009 - 2011 (10 - 17 years, and their height-for-age was evaluated during these two periods.Awealth index was used to classify the SEP of each child’s family as low, medium, or high. Social mobility was categorized as upward mobility or no upward mobility. Linear mixed models were used. Results: We evaluated 1,716 children (71.4% of baseline after 10 years, and 60.6% of the families showed upward mobility, with a higher percentage among the lowest economic classes. A higher height-for-age was also observed among those from families with a high SEP both in childhood (low SEP= -0.35 z-score; high SEP= 0.15 z-score, p < 0.01 and adolescence (low SEP= -0.01 z-score; high SEP= 0.45 z-score, p < 0.01, whereas upward mobility did not affect their linear growth. Conclusion: Expressive social mobility was observed, but SEP in childhood and social mobility did not greatly influence linear growth through childhood in this central-western Brazilian cohort.

    Full Text Available Personality growth as a socio-psychological problem is a multi-complex phenomenon that targets Self-identity, Self-actualization, and other areas. During the last decade scientists started studying other factors limiting the personality growth, such as stress and post-trauma. However, the Survival Roles, the socio-individual patterns based on neurophysiological and psychological defense mechanisms blocking the personality Self-actualization, social interaction and professional business qualities, are rarely discussed. Thus this study based on Survival Roles may extend the personality growth oriented concepts and therapy modality tools. This study showed a correlation between Survival Role patterns, stress resilience, and survival reflexes (integrative units of the nervous system functions. Comparative data on 464 business professionals from high management jobs (Study Group — n=340, and Control Group — n=124 participated in this research which found 70.9 % (n=329 of the total group was in stress. This stress activated socio-individual Survival Roles and protective reflex patterns which responded with reactivity, over-protection, non-constructive interactions with others and limited business strategies. The MNRI® reflex integrative training used in this study demonstrated improvement of functions of the protective reflex patterns effected positively the survival mechanisms including increased stress resilience, and decreased negative effect of Survival Roles. MNRI® proposes a new paradigm in the realm of personality growth and socio-interpersonal activity, and supports the neurophysiological aspects to optimize the overall quality of life of business professionals from a variety of high management business areas.

    2014-01-01

    BACKGROUND: Exposure to ultrafine particles (UFP) has been linked to cardiovascular and lung diseases. Combustion of jet fuel and diesel powered handling equipment emit UFP resulting in potentially high exposure levels among employees working at airports. High levels of UFP have been reported...... at several airports, especially on the apron, but knowledge on individual exposure profiles among different occupational groups working at an airport is lacking. PURPOSE: The aim of this study was to compare personal exposure to UFP among five different occupational groups working at Copenhagen Airport (CPH......). METHOD: 30 employees from five different occupational groups (baggage handlers, catering drivers, cleaning staff and airside and landside security) at CPH were instructed to wear a personal monitor of particle number concentration in real time and a GPS device. The measurements were carried out on 8 days...

    The uptake of the Personally Controlled Electronic Health Record (PCEHR) has been slowly building momentum in Australia. The purpose of the PCEHR is to collect clinically important information from multiple healthcare providers to provide a secure electronic record to patients and their authorised healthcare providers that will ultimately enhance the efficiency and effectiveness of healthcare delivery. Reasons for the slow uptake of the PCEHR and future directions to improve its usefulness is discussed later. © 2016 Royal Australasian College of Physicians.

  1. Reward Devaluation: Dot-Probe Meta-Analytic Evidence of Avoidance of Positive Information in Depressed Persons

    Winer, E. Samuel; Salem, Taban

    2015-01-01

    Cognitive theories of depression and anxiety have traditionally emphasized the role of attentional biases in the processing of negative information. The dot-probe task has been widely used to study this phenomenon. Recent findings suggest that biased processing of positive information might also be an important aspect of developing psychopathological symptoms. However, despite some evidence suggesting persons with symptoms of depression and anxiety may avoid positive information, many dot-probe studies have produced null findings. The present review used conventional and novel meta-analytic methods to evaluate dot-probe attentional biases away from positive information and, for comparison, toward negative information, in depressed and anxious individuals. Results indicated that avoidance of positive information is a real effect exhibiting substantial evidential value among persons experiencing psychopathology, with individuals evidencing primary symptoms of depression clearly demonstrating this effect. Different theoretical explanations for these findings are evaluated, including those positing threat-processing structures, even-handedness, self-regulation, and reward devaluation, with the novel theory of reward devaluation emphasized and expanded. These novel findings and theory suggest that avoidance of prospective reward helps to explain the cause and sustainability of depressed states. Suggestions for future research and methodological advances are discussed. PMID:26619211

    To investigate the effects of positive nutritional support in the early stage after birth on the nutritional status during hospitalization and extrauterine growth restriction (EUGR) in preterm infants. There were two groups of preterm infants. Group A (n=99) was given the previous nutritional program, while group B (n=101) was given positive nutritional support. The nutritional intake, growth rate and EUGR incidence were compared between the two groups. Compared with group A, group B had significantly higher enteral calorie intake and total calorie intake within one week after birth. Additionally, the age of first feeding, time of regaining birth weight, duration of intravenous nutrition, time to full enteral feeding, and length of hospital stay in group B were all shorter than in group A. Group B also had less physiological weight loss than group A. Among the preterm infants with a gestational age less than 32 weeks, group B had faster increases in body weight, head circumference, and body length and a lower incidence of EUGR compared with group A. Among the preterm infants with a gestational age not less than 32 weeks, group B had faster increases in body weight and a lower incidence of EUGR (evaluated based on body weight and head circumference) compared with group A. During hospitalization, group B had significantly lower incidence of feeding intolerance, necrotizing enterocolitis, and sepsis than group A. Positive nutritional support strategy, applied in preterm infants early after birth, can effectively improve their nutritional status during hospitalization and reduce the incidence of EUGR without increasing the incidence of related complications during hospitalization.

    This study examined the relationship between flow experience and place identity, based on eudaimonistic identity theory (EIT) which prioritizes self-defining activities as important for an individual's identification of his/her goals, values, beliefs, and interests corresponding to one's own identity development or enhancement. This study focuses on place identity, the identity's features relating to a person's relation with her/his place. The study is also based on flow theory, according to which some salient features of an activity experience are important for happiness and well-being. Questionnaire surveys on Italian and Greek residents focused on their perceived flow and place identity in relation to their own specific local place experiences. The overall findings revealed that flow experience occurring in one's own preferred place is widely reported as resulting from a range of self-defining activities, irrespective of gender or age, and it is positively and significantly associated with one's own place identity. Such findings provide the first quantitative evidence about the link between flow experienced during meaningfully located self-defining activities and identity experienced at the place level, similarly to the corresponding personal and social levels that had been previously already empirically tested. Results are also discussed in terms of their implications for EIT's understanding and enrichment, especially by its generalization from the traditional, personal identity level up to that of place identity. More generally, this study has implications for maintaining or enhancing one's own place identity, and therefore people-place relations, by means of facilitating a person's flow experience within psychologically meaningful places.

    Personal growth initiative (PGI), defined as being proactive about one's personal development, is critical to graduate students' academic success. Prior research has shown that students' PGI can be enhanced through interventions that focus on stimulating developmental activities. Within this study, we aimed to investigate whether an intervention that stimulates development in the area of one's personal strengths (strengths intervention) has more beneficial effects on students' PGI than an intervention that stimulates development in the area of individual deficiencies (deficiency intervention). We conducted 2 longitudinal field experiments to investigate the effects of the 2 interventions on students' PGI (Experiment 1) and the potential mediating role of psychological capital (PsyCap) in this regard (Experiment 2). In Experiment 1, 105 (N = 105) university students participated in either a strengths intervention or a deficiency intervention. Results indicated that the strengths intervention increased the students' PGI in the short but not in the long term, whereas the deficiency intervention did not affect PGI. Ninety students (N = 90) participated in Experiment 2, in which we slightly refined both interventions by putting a stronger emphasis on the ongoing development of strengths (strengths intervention) or correction of deficiencies (deficiency intervention) by adding posttraining assignments. Results suggested that participating in both interventions led to increases in PGI over a 3-month period, but that these increases were bigger for the strengths intervention group. Furthermore, the relationship between the strengths intervention and PGI was mediated by hope as one component of PsyCap. PsycINFO Database Record (c) 2015 APA, all rights reserved.

    The present study investigated patterns of normative change in personality traits across the adult life span (19 through 74 years of age). We examined change in extraversion, agreeableness, conscientiousness, neuroticism, openness to experience and honesty-humility using data from the first 6 annual waves of the New Zealand Attitudes and Values Study (N = 10,416; 61.1% female, average age = 49.46). We present a cohort-sequential latent growth model assessing patterns of mean-level change due to both aging and cohort effects. Extraversion decreased as people aged, with the most pronounced declines occurring in young adulthood, and then again in old age. Agreeableness, indexed with a measure focusing on empathy, decreased in young adulthood and remained relatively unchanged thereafter. Conscientiousness increased among young adults then leveled off and remained fairly consistent for the rest of the adult life span. Neuroticism and openness to experience decreased as people aged. However, the models suggest that these latter effects may also be partially due to cohort differences, as older people showed lower levels of neuroticism and openness to experience more generally. Honesty-humility showed a pronounced and consistent increase across the adult life span. These analyses of large-scale longitudinal national probability panel data indicate that different dimensions of personality follow distinct developmental processes throughout adulthood. Our findings also highlight the importance of young adulthood (up to about the age of 30) in personality trait development, as well as continuing change throughout the adult life span.

    Objective. The aim of this study was to compare impulsivity and risky decision making among HIV-positive and negative heroin dependent persons. Methods. We compared different dimensions of impulsivity and risky decision making in two groups of 60 HIV-positive and 60 HIV-negative male heroin dependent persons. Each group was comprised of equal numbers of current (treatment seeker) and former (abstinent) heroin addicts. Data collection tools included Balloon Analogue Risk Task (BART), Iowa Gambling Task (IGT), Barratt Impulsiveness Scale (BIS), and Zuckerman Sensation Seeking Scale (SSS). Results. In SSS, comprised of four subscales including thrill and adventure seeking (TAS), experience seeking (ES), disinhibition (DIS), and boredom susceptibility (BS), there was a borderline difference in DIS (P = 0.08) as HIV-positive group scored higher than HIV-negative group. Also, ES and total score were significantly higher among HIV-positive patients. In BART, HIV-positive subjects scored higher in risk taking than HIV-negative subjects as reflected in higher Average Number of puffs in Successful Balloons (ANSB). In BIS, HIV-positive group scored significantly higher in cognitive impulsivity (CI) (P = 0.03) and nonplanning impulsivity (NPI) (P = 0.05) in comparison to HIV-negative group. Also, current heroin addicts scored significantly higher in NPI compared to former addict HIV-negative participants (P = 0.015). IGT did not show any significant difference between groups. Conclusion. Higher levels of impulsivity and risk taking behaviors among HIV-positive heroin addicts will increase serious concerns regarding HIV transmission from this group to other opiate dependents and healthy people.

    Experiential avoidance (EA) is an important factor in maintaining different forms of psychopathology including borderline personality pathology (BPD). So far little is known about the functions of EA, BPD features and general psychopathology for positive emotions. In this study we investigated three different anticipated pathways of their influence on positive emotions. A total of 334 subjects varying in general psychopathology &/or BPD features completed an online survey including self-ratings of BPD features, psychopathology, negative and positive emotions, and EA. Measures of positive emotions included both a general self-rating (PANAS) and emotional changes induced by two positive movie clips. Data were analyzed by means of path analysis. In comparing the three path models, one model was found clearly superior: In this model, EA acts as a mediator of the influence of psychopathology, BPD features, and negative emotions in the prediction of both measures of positive emotions. EA plays a central role in maintaining lack of positive emotions. Therapeutic implications and study limitations are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Mental health inequalities are an increasingly important global problem. This study examined the association between mental health status and certain socioeconomic indicators (personal social position and the socioeconomic status of the family) in Slovenian 15-year-old adolescents. Data originate from the WHO-Collaborative cross-national 'Health Behavior in School-aged Children' study conducted in Slovenia in 2010 (1,815 secondary school pupils, aged 15). Mental health status was measured by: KIDSCREEN-10, the Strength and Difficulties questionnaire (SDQ), a life satisfaction scale, and one question about feelings of depression. Socioeconomic position was measured by the socioeconomic status of the family (Family Affluence Scale, perceived material welfare, family type, occupational status of parents) and personal social position (number of friends and the type of school). Logistic regression and a multivariate analysis of variance (MANOVA) were performed. Girls had 2.5-times higher odds of suffering feelings of depression (p mental health than those with a higher socioeconomic position. Because of the financial crisis, we can expect an increase in social inequalities and a greater impact on adolescents' mental health status in Slovenia in the future.

    We performed a retrospective analysis of the association between tumor HPV status and the demographic and clinicopathological parameters of 83 patients with oropharyngeal squamous cell carcinoma at Hokkaido University Hospital, Japan, between 1998 and 2010. The parameters included age, gender, tumor subsite, Tumor-Node-Metastasis (TNM) stage, and overall survival. HPV status was established by multiplex polymerase chain reaction analysis. Of the 83 oropharyngeal cancers, 22 were positive for HPV-16, two for HPV-18, and one for HPV-35 and HPV-58. Kaplan-Meier survival analysis showed improved overall survival rates in patients with HPV-positive tumors (p=0.0024) compared with HPV-negative tumors. Of the 51 patients who received chemoradiotherapy, HPV-positive patients experienced better overall survival than HPV-negative patients (p=0.0024). HPV status is a significantly favorable prognostic factor in oropharyngeal cancer in Japan. (author)

    Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0-1.5 nmol) and 17-Hydroxyprogesterone >180 nmol/L (transsexual patients undergoing therapy with high-dose oestrogen and progestogens. Progesterone receptor positivity has been described previously in meningiomas. 17-Hydroxyprogesterone is elevated in CAH and has affinity and biological activity at the progesterone receptor. Therefore, we hypothesise that patients who have long-standing increased adrenal androgen precursor concentrations may be at risk of meningioma growth. Patients with long-standing CAH (particularly if not optimally controlled) may present with other complications, which may be related to long-standing elevated androgen or decreased glucocorticoid levels.Chronic poor control of CAH is associated with adrenal myelolipoma and adrenal rest tissue tumours.Meningiomas are sensitive to endocrine stimuli including progesterone, oestrogen and androgens as they express the relevant receptors.

    Sixty adults in outpatient psychotherapy completed the NEO Personality Inventory--Revised (NEO PI-R, P. T. Costa & R. R. McCrae, 1992a). Half were instructed to fake good and half were given standard instructions. All completed the Interpersonal Adjective Scale--Revised, Big Five (J. S. Wiggins & P. D. Trapnell, 1997) under standard instructions, and their therapists completed the observer rating form of the NEO Five-Factor Inventory. A comparison group of 30 students completed the NEO PI-R under standard instructions. Standard and fake-good participants obtained significantly different NEO PI-R domain scores. Correlations between the NEO PI-R and criterion measures were significantly lower for faking than for standard patients. Validity scales for the NEO PI-R (J. A. Schinka, B. N. Kinder, & T. Kremer, 1997) were moderately accurate in discriminating faking from standard patients, but were only marginally accurate in discriminating faking patients from students.

Participants from Australia, North America, Brazil, and Thailand were administered a 5-test neurocognitive battery. Z scores and the neurocognitive performance outcome measure, the quantitative neurocognitive performance z score (QNPZ-5), were calculated using US norms. Neurocognitive impairment was defined as z scores penetration effectiveness rank of antiretroviral regimens were not. In this HIV-positive population with high CD4 cell counts, neurocognitive impairment was associated with prior CVD. Lower neurocognitive performance was associated with prior CVD, hypertension, and hypercholesterolemia, but not conventional HAD risk factors. The contribution of CVD and cardiovascular risk factors to the neurocognition of HIV-positive populations warrants further investigation.

  19. The adapter protein, Grb10, is a positive regulator of vascular endothelial growth factor signaling.

    Vascular endothelial growth factor (VEGF) is an important regulator of vasculogenesis and angiogenesis. Activation of VEGF receptors leads to the recruitment of SH2 containing proteins which link the receptors to the activation of signaling pathways. Here we report that Grb10, an adapter protein of which the biological role remains unknown, is tyrosine phosphorylated in response to VEGF in endothelial cells (HUVEC) and in 293 cells expressing the VEGF receptor KDR. An intact SH2 domain is required for Grb10 tyrosine phosphorylation in response to VEGF, and this phosphorylation is mediated in part through the activation of Src. In HUVEC, VEGF increases Grb10 mRNA level. Expression of Grb10 in HUVEC or in KDR expressing 293 cells results in an increase in the amount and in the tyrosine phosphorylation of KDR. In 293 cells, this is correlated with the activation of signaling molecules, such as MAP kinase. By expressing mutants of Grb10, we found that the positive action of Grb10 is independent of its SH2 domain. Moreover, these Grb10 effects on KDR seem to be specific since Grb10 has no effect on the insulin receptor, and Grb2, another adapter protein, does not mimic the effect of Grb10 on KDR. In conclusion, we propose that VEGF up-regulates Grb10 level, which in turn increases KDR molecules, suggesting that Grb10 could be involved in a positive feedback loop in VEGF signaling.

    Overexpression of human epidermal growth factor receptor 2 (HER2) is found in about 20% of breast cancer patients. With treatment using trastuzumab, an anti-HER2 monoclonal antibody, systemic control is improved. Nonetheless, the incidence of brain metastasis does not be improved, rather seems to be increased in HER2-positive breast cancer. The mainstay treatment for brain metastases is radiotherapy. According to the number of metastatic lesions and performance status of patients, radiosurgery or whole brain radiotherapy can be performed. The concurrent use of a radiosensitizer further improves intracranial control. Due to its large molecular weight, trastuzumab has a limited ability to cross the blood-brain barrier. However, small tyrosine kinase inhibitors such as lapatinib, has been noted to be a promising agent that can be used as a radiosensitizer to affect HER2-positive breast cancer. This review will outline general management of brain metastases and will focus on preclinical findings regarding the radiosensitizing effect of small molecule HER2 targeting agents.

    Our aim with this qualitative study was to understand the role of personal values, meaning, and impact of drug use among HIV-positive men who have sex with men (MSM) who struggle with methamphetamine use. Participants were 22 MSM recruited from an ethnically diverse county in the San Francisco Bay area of California. Grounded theory was used to analyze the data collected in individual interviews. Emergent constructs of context, meaning, and perceived impact were identified and are described in a theoretical narrative format. The importance of broadening our understanding of HIV and methamphetamine addiction and their interaction is highlighted. This study contributes to the understanding of the complexity of methamphetamine use within the specific population of MSM living with HIV/ AIDS, and suggests possible directions for addressing important maintaining factors like adaptive use and enhancing factors that could contribute to an individual's ability to make better choices based on meaning and personal values.

    Although interpersonal interactions are thought to affect psychopathology in schizophrenia, there is a paucity of data about how older adults with schizophrenia manage interpersonal conflicts. This paper examines interpersonal conflict strategies and their impact on positive symptom remission in older adults with schizophrenia spectrum disorders. The schizophrenia group consisted of 198 persons aged 55 years and over living in the community who developed schizophrenia before age 45. A community comparison group (n = 113) was recruited using randomly selected block-groups. Straus' Conflict Tactics Scale (CTS) was used to assess the ways that respondents handled interpersonal conflicts. Seven conflict management subscales were created based on a principal component analysis with equamax rotation of items from the CTS. The order of the frequency of the tactics that was used was similar for both the schizophrenia and community groups. Calm and Pray tactics were the most commonly used, and the Violent and Aggressive tactics were rarely utilized. In two separate logistic regression analysis, after controlling for confounding variables, positive symptom remission was found to be associated significantly with both the Calm and Pray subscales. The findings suggest that older persons with schizophrenia approximate normal distribution patterns of conflict management strategies and the most commonly used strategies are associated with positive symptom remission.

    Full Text Available Strong associations of Neuroticism and Extraversion with positive affects (PA and negative affects (NA have been reported in the international literature. This study aimed to evaluate the occurrence of such relationships in a Brazilian sample, and also to investigate the role of Conscientiousness, Agreeableness and Openness in the prediction of PA and NA through the use of a hybrid structural model. Participants were 319 university students, between 17 and 37 years of age (mean = 21.5, SD = 4.9. Approximately 64% of the students were female and 36% male. Results showed that Neuroticism was the most important predictor of PA and NA, followed by Conscientiousness, but not Extraversion. Surprisingly, Agreeableness was shown to be a weak prediction for NA, but had no relationship with PA. As expected, Openness showed no relationship with PA or NA. These results are partially in agreement with the international literature but some important differences were detected.

    INTRODUCTION: There is paucity of data related to potential gender differences in the use of interventions to prevent and treat cardiovascular disease (CVD) among HIV-positive individuals. We investigated whether such differences exist in the observational D:A:D cohort study. METHODS: Participants...... of follow-up for which individuals were at high CVD risk. In fully adjusted models, women were less likely to receive CVD interventions than men (LLDs: relative rate 0.83 [0.78, 0.88]; ACEIs: 0.93 [0.86, 1.01]; ICPs: 0.54 [0.43, 0.68]), except for the receipt of anti-hypertensives (1.17 [1.10, 1.......25]). CONCLUSION: The use of most CVD interventions was lower among women than men. Interventions are needed to ensure that all HIV-positive persons, particularly women, are appropriately monitored for CVD and, if required, receive appropriate CVD interventions....

    This study examined the relationship between flow experience and place identity, based on eudaimonistic identity theory (EIT) which prioritizes self-defining activities as important for an individual’s identification of his/her goals, values, beliefs, and interests corresponding to one’s own identity development or enhancement. This study focuses on place identity, the identity’s features relating to a person’s relation with her/his place. The study is also based on flow theory, according to which some salient features of an activity experience are important for happiness and well-being. Questionnaire surveys on Italian and Greek residents focused on their perceived flow and place identity in relation to their own specific local place experiences. The overall findings revealed that flow experience occurring in one’s own preferred place is widely reported as resulting from a range of self-defining activities, irrespective of gender or age, and it is positively and significantly associated with one’s own place identity. Such findings provide the first quantitative evidence about the link between flow experienced during meaningfully located self-defining activities and identity experienced at the place level, similarly to the corresponding personal and social levels that had been previously already empirically tested. Results are also discussed in terms of their implications for EIT’s understanding and enrichment, especially by its generalization from the traditional, personal identity level up to that of place identity. More generally, this study has implications for maintaining or enhancing one’s own place identity, and therefore people–place relations, by means of facilitating a person’s flow experience within psychologically meaningful places.

    The author gives his views on the intermediate-range perspectives, short-term perspectives, and long-term perspectives of positive muons and pions in materials research. The short-term perspectives include questions that had to remain open at the present conference but that should be answered by the time of the next conference. By long-term perspectives he means the early and middle 1990's, when a new generation of powerful neutron spallation sources and perhaps also a kaon factory should be operating. If laid out appropriately, these installations should produce pion and muon beams that are much stronger than the existing ones and that possess interesting time structures. They should enable us to investigate problems definitely beyond our present reach. Everything between the time-scales of the 'short term' and the 'long-term' future will be considered as 'intermediate range'. The author deals with the role that μ + SR might play in 'materials science', those aspects of condensed-matter studies that have to do with the purity and, in the case of solids, with the microstructure and the imperfections (structural defects) of materials.

    The European AIDS Clinical Society (EACS) guidelines are intended for all clinicians involved in the care of HIV-positive persons, and are available in print, online, and as a free App for download for iPhone and Android. The 2015 version of the EACS guidelines contains major revisions in all sections; antiretroviral treatment (ART), comorbidities, coinfections and opportunistic diseases. Among the key revisions is the recommendation of ART for all HIV-positive persons, irrespectively of CD4 count, based on the Strategic Timing of AntiRetroviral Treatment (START) study results. The recommendations for the preferred and the alternative ART options have also been revised, and a new section on the use of pre-exposure prophylaxis (PrEP) has been added. A number of new antiretroviral drugs/drug combinations have been added to the updated tables on drug-drug interactions, adverse drug effects, dose adjustment for renal/liver insufficiency and for ART administration in persons with swallowing difficulties. The revisions of the coinfection section reflect the major advances in anti-hepatitis C virus (HCV) treatment with direct-acting antivirals with earlier start of treatment in individuals at increased risk of liver disease progression, and a phasing out of interferon-containing treatment regimens. The section on opportunistic diseases has been restructured according to individual pathogens/diseases and a new overview table has been added on CD4 count thresholds for different primary prophylaxes. The diagnosis and management of HIV infection and related coinfections, opportunistic diseases and comorbidities continue to require a multidisciplinary effort for which the 2015 version of the EACS guidelines provides an easily accessable and updated overview. © 2015 British HIV Association.

    International trade has grown considerably during the process of globalization. Complex supply chains for the production of goods have resulted in an increasingly connected International Trade Network (ITN). Traditionally, direct trade relations between industries have been regarded as mediators of supply and demand spillovers. With increasing network connectivity the question arises if higher-order relations become more important in explaining a national sector's susceptibility to supply and demand changes of its trading partner. In this study we address this question by investigating empirically to what extent the topological properties of the ITN provide information about positive correlations in the production of two industry sectors. We observe that although direct trade relations between industries serve as important indicators for correlations in the industries' value added growth, opportunities of substitution for required production inputs as well as second-order trade relations cannot be neglected. Our results contribute to a better understanding of the relation between trade and economic productivity and can serve as a basis for the improvement of crisis spreading models that evaluate contagion threats in the case of a node's failure in the ITN.

    Understanding the catalyzed formation and evolution of lithium-oxide products in Li-O2 batteries is central to the development of next-generation energy storage technology. Catalytic sites, while effective in lowering reaction barriers, often become deactivated when placed on the surface of an oxygen electrode due to passivation by solid products. Here we investigate a mechanism for alleviating catalyst deactivation by dispersing Pd catalytic sites away from the oxygen electrode surface in a well-structured anodic aluminum oxide (AAO) porous membrane interlayer. We observe the cross-sectional product growth and evolution in Li-O2 cells by characterizing products that grow from the electrode surface. Morphological and structural details of the products in both catalyzed and uncatalyzed cells are investigated independently from the influence of the oxygen electrode. We find that the geometric decoration of catalysts far from the conductive electrode surface significantly improves the reaction reversibility by chemically facilitating the oxidation reaction through local coordination with PdO surfaces. The influence of the catalyst position on product composition is further verified by ex situ X-ray photoelectron spectroscopy and Raman spectroscopy in addition to morphological studies.

    Vestibular dysfunction is a well-recognized complication of type 2 diabetes (DM) that may contribute to increased fall risk. The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with DM. The impact of DM on the otolith organs of the vestibular system in people with BPPV is unknown. The purpose of this study was to analyze otolith function using vestibular-evoked myogenic potential (VEMP) tests in people with DM and concurrent BPPV (BPPV + DM), and to examine the relationships between VEMP variables and diabetes-related variables. Prospective, cross-sectional study. Tertiary academic medical center. Participants 40 to 65 years were recruited in four groups: controls (n = 20), people with DM (n = 19), BPPV (n = 18), and BPPV + DM (n = 14). Saccule and utricle function were examined using cervical VEMP (cVEMP) and ocular VEMP (oVEMP), respectively. Diabetes-related variables such as HbA1c, duration of diabetes, and presence of sensory impairment due to diabetes were collected. The frequency of abnormal cVEMP responses was higher in the DM (p = 0.005), BPPV (p = 0.003), and BPPV + DM (p diabetes, higher HbA1c levels were correlated with prolonged P1 (p = 0.03) and N1 latencies (p = 0.03). The frequency of abnormal oVEMP responses was not different between groups (p = 0.2). Although BPPV and DM may independently affect utricle and saccule function, they do not seem to have a distinct cumulative effect.

    Full Text Available Most of the research on Bayesian reasoning aims to answer theoretical questions about the extent to which people are able to update their beliefs according to the Bayes Theorem (Baratgin & Politzer, 2006; Barbey & Sloman, 2007; Gigerenzer & Hoffrage, 1995 about the evolutionary nature of Bayesian inference (Brase, 2002, 2007; Gigerenzer & Hoffrage, 1995, or about the role of cognitive abilities in Bayesian inference (Johnson & Tubau, 2013; Lesage, Navarrete, & De Neys, 2013; Sirota, Juanchich, & Hagmayer, 2014. Few studies aim to answer practical, mainly health-related questions, such as, questions such as ‘What does it mean to have a positive test in a context of cancer screening?’ or ‘What is the best way to communicate a medical test result so a patient will understand it?. This type of research aims to translate the empirical finding into effective ways of providing risk information. In addition, the applied research often adopts the paradigms and methods of the theoretically-motivated research. But sometimes it works the other way around, and the theoretical research borrows the importance of the practical question in the medical context. The study of Bayesian reasoning is relevant to risk communication in that,, to be as useful as possible, applied research should employ specifically tailored methods and contexts specific to the recipients of the risk information. In this paper, we concentrate on the communication of the result of medical tests and outline the epidemiological and test parameters that affect the predictive power of a test – whether it is correct or not. Building on this, we draw up recommendations for better practice to convey the results of medical tests that could inform health policy makers (e.g. what are the drawbacks of mass screenings?, be used by health practitioners and, in turn, help patients to make better and more informed decisions.

    Background Physician-delivered preventive counseling is important for the prevention and management of chronic diseases. Data from the U.S. indicates that medical students with healthy personal habits have a better attitude towards preventive counseling. However, this association and its correlates have not been addressed in rapidly urbanized settings where chronic disease prevention strategies constitute a top public health priority. This study examines the association between personal health practices and attitudes toward preventive counseling among first and fifth-year students from 8 medical schools in Bogotá, Colombia. Methods During 2006, a total of 661 first- and fifth-year medical students completed a culturally adapted Spanish version of the "Healthy Doctor = Healthy Patient" survey (response rate = 78%). Logistic regression analyses were used to assess the association between overall personal practices on physical activity, nutrition, weight control, smoking, alcohol use (main exposure variable) and student attitudes toward preventive counseling on these issues (main outcome variable), stratified by year of training and adjusting by gender and medical training-related factors (basic knowledge, perceived adequacy of training and perception of the school's promotion on each healthy habit). Results The median age and percentage of females for the first- and fifth-year students were 21 years and 59.5% and 25 years and 65%, respectively. After controlling for gender and medical training-related factors, consumption of ≥ 5 daily servings of fruits and/or vegetables, not being a smoker or binge drinker were associated with a positive attitude toward counseling on nutrition (OR = 4.71; CI = 1.6–14.1; p = 0.006 smoking (OR = 2.62; CI = 1.1–5.9; p = 0.022), and alcohol consumption (OR = 2.61; CI = 1.3–5.4; p = 0.009), respectively.

    Molecularly targeted therapies, directed against the features of a given tumor, have allowed for a personalized approach to the treatment of advanced non-small-cell lung cancer (NSCLC). The reversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib had undergone turbulent clinical development until it was discovered that these agents have preferential activity in patients with NSCLC harboring activating EGFR mutations. Since then, a number of phase 3 clinical trials have collectively shown that EGFR-TKI monotherapy is more effective than combination chemotherapy as first-line therapy for EGFR mutation-positive advanced NSCLC. The next generation of EGFR-directed agents for EGFR mutation-positive advanced NSCLC is irreversible TKIs against EGFR and other ErbB family members, including afatinib, which was recently approved, and dacomitinib, which is currently being tested in phase 3 trials. As research efforts continue to explore the various proposed mechanisms of acquired resistance to EGFR-TKI therapy, agents that target signaling pathways downstream of EGFR are being studied in combination with EGFR TKIs in molecularly selected advanced NSCLC. Overall, the results of numerous ongoing phase 3 trials involving the EGFR TKIs will be instrumental in determining whether further gains in personalized therapy for advanced NSCLC are attainable with newer agents and combinations. This article reviews key clinical trial data for personalized NSCLC therapy with agents that target the EGFR and related pathways, specifically based on molecular characteristics of individual tumors, and mechanisms of resistance

    Acquired resistance to lapatinib, a human epidermal growth factor receptor 2 kinase inhibitor, remains a clinical problem for women with human epidermal growth factor receptor 2-positive advanced breast cancer, as metastasis is commonly observed in these patients. Niclosamide, an anti-helminthic agent, has recently been shown to exhibit cytotoxicity to tumor cells with stem-like characteristics. This study was designed to identify the mechanisms underlying lapatinib resistance and to determine whether niclosamide inhibits lapatinib resistance by reversing epithelial-mesenchymal transition. Here, two human epidermal growth factor receptor 2-positive breast cancer cell lines, SKBR3 and BT474, were exposed to increasing concentrations of lapatinib to establish lapatinib-resistant cultures. Lapatinib-resistant SKBR3 and BT474 cells exhibited up-regulation of the phenotypic epithelial-mesenchymal transition markers Snail, vimentin and α-smooth muscle actin, accompanied by activation of nuclear factor-кB and Src and a concomitant increase in stem cell marker expression (CD44(high)/CD24(low)), compared to naive lapatinib-sensitive SKBR3 and BT474 cells, respectively. Interestingly, niclosamide reversed epithelial-mesenchymal transition, induced apoptosis and inhibited cell growth by perturbing aberrant signaling pathway activation in lapatinib-resistant human epidermal growth factor receptor 2-positive cells. The ability of niclosamide to alleviate stem-like phenotype development and invasion was confirmed. Collectively, our results demonstrate that lapatinib resistance correlates with epithelial-mesenchymal transition and that niclosamide inhibits lapatinib-resistant cell viability and epithelial-mesenchymal transition. These findings suggest a role of niclosamide or derivatives optimized for more favorable bioavailability not only in reversing lapatinib resistance but also in reducing metastatic potential during the treatment of human epidermal growth factor receptor

    Nebulized aerosol drug delivery during the administration of noninvasive positive pressure ventilation (NPPV) is commonly implemented. While studies have shown improved patient outcomes for this therapeutic approach, aerosol delivery efficiency is reported to be low with high variability in lung-deposited dose. Excipient enhanced growth (EEG) aerosol delivery is a newly proposed technique that may improve drug delivery efficiency and reduce intersubject aerosol delivery variability when coupled with NPPV. A combined approach using in vitro experiments and computational fluid dynamics (CFD) was used to characterize aerosol delivery efficiency during NPPV in two new nasal cavity models that include face mask interfaces. Mesh nebulizer and in-line dry powder inhaler (DPI) sources of conventional and EEG aerosols were both considered. Based on validated steady-state CFD predictions, EEG aerosol delivery improved lung penetration fraction (PF) values by factors ranging from 1.3 to 6.4 compared with conventional-sized aerosols. Furthermore, intersubject variability in lung PF was very high for conventional aerosol sizes (relative differences between subjects in the range of 54.5%-134.3%) and was reduced by an order of magnitude with the EEG approach (relative differences between subjects in the range of 5.5%-17.4%). Realistic in vitro experiments of cyclic NPPV demonstrated similar trends in lung delivery to those observed with the steady-state simulations, but with lower lung delivery efficiencies. Reaching the lung delivery efficiencies reported with the steady-state simulations of 80%-90% will require synchronization of aerosol administration during inspiration and reducing the size of the EEG aerosol delivery unit. The EEG approach enabled high-efficiency lung delivery of aerosols administered during NPPV and reduced intersubject aerosol delivery variability by an order of magnitude. Use of an in-line DPI device that connects to the NPPV mask appears to be a

    The Positive and Negative Affect Schedule (PANAS) is a widely used measure of emotional experience. The factor structure of the PANAS has been examined predominantly with cross-sectional designs, which fails to disaggregate within-person variation from between-person differences. There is still uncertainty as to the factor structure of positive and negative affect and whether they constitute 2 distinct independent factors. The present study examined the within-person and between-person factor structure of the PANAS in 2 independent samples that reported daily affect over 7 and 14 occasions, respectively. Results from multilevel confirmatory factor analyses revealed that a 2-factor structure at both the within-person and between-person levels, with correlated specific factors for overlapping items, provided good model fit. The best-fitting solution was one where within-person factors of positive and negative affect were inversely correlated, but between-person factors were independent. The structure was further validated through multilevel structural equation modeling examining the effects of cognitive interference, daily stress, physical symptoms, and physical activity on positive and negative affect factors.

    While adaptive perfectionism ensures good overall performance, maladaptive perfectionism is associated with emotional disorders for which psychological treatment is sought. There are many factors that can explain the development of this disorder throughout childhood. The present study analyzed to what extent the child's personality traits and excessive parental demands can predict maladaptive perfectionism, and, in turn, also analyzed how this relates to positive emotions and depressive symptoms in a sample of 404 Argentinian children (M age = 10.30; SD = 1.03). Stepwise multiple regression analyses and Kruskal-Wallis and Mann-Whitney tests were performed. Results showed that excessive parental demands, together with high child neuroticism increased the likelihood of developing perfectionism (p children's mental health.

    Older people's emotional distress is often related to rumination processes focused on past vital events occurred during their lives. The specific coping strategies displayed to face those events may contribute to explain older adults' current well-being: they can perceive that they have obtained personal growth after those events and/or they can show a tendency to have intrusive thoughts about those events. This paper describes the development and analysis of the psychometric properties of the Scales for the Assessment of the Psychological Impact of Past Life Events (SAPIPLE): the past life events-occurrence scale (LE-O), ruminative thought scale (LE-R) and personal growth scale (LE-PG). Participants were 393 community dwelling elderly (mean age=71.5 years old; SD=6.9). In addition to the SAPIPLE scales, depressive symptomatology, anxiety, psychological well-being, life satisfaction, physical function and vitality have been assessed. The inter-rater agreement's analysis suggests the presence of two factors in the LE-O: positive and negative vital events. Confirmatory Factor Analysis (CFA) supported this two-dimensional structure for both the LE-R and the LE-PG. Good internal consistency indexes have been obtained for each scale and subscale, as well as good criterion and concurrent validity indexes. Both ruminative thoughts about past life events and personal growth following those events are related to older adults' current well-being. The SAPIPLE presents good psychometric properties that justify its use for elderly people. Copyright © 2012 SEGG. Published by Elsevier Espana. All rights reserved.

  3. Trust, Personal Moral Codes, and the Resource-Advantage Theory of Competition: Explaining Productivity, Economic Growth, and Wealth Creation

    Full Text Available Scholars agree that societal-level moral codes that promote social trust also promote wealth creation.  However, what specific kinds of societal-level moral codes promote social trust?  Also, by what specific kind of competitive process does social trust promote wealth creation?  Because societal-level moral codes are composed of or formed from peoples’ personal moral codes, this article explores a theory of ethics, known as the “Hunt-Vitell” theory of ethics, that illuminates the concept of personal moral codes and uses the theory to discuss which types of personal moral codes foster trust and distrust in society.  This article then uses resource-advantage (R-A theory, one of the most completely articulated dynamic theories of competition, to show the process by which trust-promoting, societal-level moral codes promote productivity and economic growth.  That is, they promote wealth creation.

    The aim of this article is to explore the positive and negative impacts of working therapeutically in complex psychological trauma (CPT), particularly the field of gender-based violence (GBV) and childhood sexual abuse (CSA), from the clinicians' perspective. The focus was on the prospect of positive gains and growth for therapists. Twenty-one clinicians ( n = 21; counselors/psychotherapists and psychologists) from National Health Service (NHS) specialist trauma services, a community mental health team, and specialist sexual assault counseling organization participated. Interpretative phenomenological analysis (IPA) was utilized to conduct single one-off interviews and analysis. Six themes were identified: Called to the work; Connection, Separation, and Oneness; Into and out of the darkness; Chaos into meaning; Reparation not repetition; and Expansion and growth. The first "Therapist Led Framework of Growth in Trauma Work" is presented. Vicarious posttraumatic growth (VPTG) was a key finding, with CPT therapists experiencing a "challenge/benefit/change" growth process. Adoption of actively relational strategies to enhance clinicians' growth process through trauma work is being proposed. The benefits of conceptualizing both the positive and negative impacts of such work for supervision, training, shaping the formal curricula, service management, and continuing professional development (CPD) are being discussed. The need for good practice guidelines on self-care internationally is highlighted.

    Abstract Background: Nebulized aerosol drug delivery during the administration of noninvasive positive pressure ventilation (NPPV) is commonly implemented. While studies have shown improved patient outcomes for this therapeutic approach, aerosol delivery efficiency is reported to be low with high variability in lung-deposited dose. Excipient enhanced growth (EEG) aerosol delivery is a newly proposed technique that may improve drug delivery efficiency and reduce intersubject aerosol delivery variability when coupled with NPPV. Materials and Methods: A combined approach using in vitro experiments and computational fluid dynamics (CFD) was used to characterize aerosol delivery efficiency during NPPV in two new nasal cavity models that include face mask interfaces. Mesh nebulizer and in-line dry powder inhaler (DPI) sources of conventional and EEG aerosols were both considered. Results: Based on validated steady-state CFD predictions, EEG aerosol delivery improved lung penetration fraction (PF) values by factors ranging from 1.3 to 6.4 compared with conventional-sized aerosols. Furthermore, intersubject variability in lung PF was very high for conventional aerosol sizes (relative differences between subjects in the range of 54.5%–134.3%) and was reduced by an order of magnitude with the EEG approach (relative differences between subjects in the range of 5.5%–17.4%). Realistic in vitro experiments of cyclic NPPV demonstrated similar trends in lung delivery to those observed with the steady-state simulations, but with lower lung delivery efficiencies. Reaching the lung delivery efficiencies reported with the steady-state simulations of 80%–90% will require synchronization of aerosol administration during inspiration and reducing the size of the EEG aerosol delivery unit. Conclusions: The EEG approach enabled high-efficiency lung delivery of aerosols administered during NPPV and reduced intersubject aerosol delivery variability by an order of magnitude. Use of an in

    The aim of this research was to study the relationship between personality dimensions, positive emotions and coping mechanisms of caregivers of patients living with HIV. This study used a cross-sectional research design. A sample comprising 56 caregivers was recruited from HIV/AIDS clinics in three teaching hospitals in Lahore, Pakistan. Data were collected between February and July 2010. Most caregivers were men, and of low socio-economic status. Individuals with both high and low extraversion used problem-focused coping, self-control and accepting responsibility, but those with low extraversion used more escape-avoidance coping, and they had also high levels of negative emotions. Those high in neuroticism used more tension-reduction coping than problem-focused coping, and experienced fewer positive emotions. Regression analysis findings revealed neuroticism as a significant predictor of negative emotions as well as emotion-focused coping, and only extraversion significantly predicted negative emotions. This research could help in devising psychological management plans for caregivers of patients living with HIV in order to assist them in coping with the burden of care. © 2016 John Wiley & Sons Australia, Ltd.

    The evidence for the effectiveness of humor-based positive psychology interventions (PPIs; i.e., interventions aimed at enhancing happiness and lowering depressive symptoms) is steadily increasing. However, little is known about who benefits most from them. We aim at narrowing this gap by examining whether personality traits and sense of humor moderate the long-term effects of humor-based interventions on happiness and depressive symptoms. We conducted two placebo-controlled online-intervention studies testing for moderation effects. In Study 1 ( N = 104) we tested for moderation effects of basic personality traits (i.e., psychoticism, extraversion, and neuroticism) in the three funny things intervention, a humor-based PPI. In Study 2 ( N = 632) we tested for moderation effects of the sense of humor in five different humor-based interventions. Happiness and depressive symptoms were assessed before and after the intervention, as well as after 1, 3, and 6 months. In Study 2, we assessed sense of humor before and 1 month after the intervention to investigate if changes in sense of humor go along with changes in happiness and depressive symptoms. We found moderating effects only for extraversion. Extraverts benefitted more from the three funny things intervention than introverts. For neuroticism and psychoticism no moderation effects were found. For sense of humor, no moderating effects were found for the effectiveness of the five humor-based interventions tested in Study 2. However, changes in sense of humor from pretest to the 1-month follow-up predicted changes in happiness and depressive symptoms. Taking a closer look, the playful attitude- and sense of humor-subscales predicted changes in happiness and depression for up to 6 months. Overall, moderating effects for personality (i.e., extraversion) were found, but none for sense of humor at baseline. However, increases in sense of humor during and after the intervention were associated with the interventions

    Thyroid hormone (TH) plays an important role in brain development, and TH deficiency during pregnancy or early postnatal periods leads to neurological disorders such as cretinism. Hypothyroidism reduces the number of parvalbumin (PV)-positive interneurons in the neocortex and hippocampus. Here we used a mouse strain (growth-retarded; grt) that shows growth retardation and hypothyroidism to examine whether somatostatin (Sst)-positive interneurons that are generated from the same pool of neural progenitor cells as PV-positive cells are also altered by TH deficiency. The number of PV-positive interneurons was significantly decreased in the neocortex and hippocampus of grt mice as compared with normal control mice. In contrast to the decrease in the number of PV neurons, the number of Sst-positive interneurons in grt mice was increased in the stratum oriens of the hippocampus and the hilus of the dentate gyrus, although their number was unchanged in the neocortex. These changes were reversed by triiodothyronine administration from postnatal day (PD) 0 to 20. TH supplementation that was initiated after PD21 did not, however, affect the number of PV- or Sst-positive cells. These results suggest that during the first three postnatal weeks, TH may be critical for the generation of subpopulations of interneurons. Copyright © 2013 The Authors.

    2010-01-01

    This paper is the last in a series of six papers that have described different aspects of mentoring. It considers the impact of mentoring when it is used in general dental practice, applying the technique of learning through positive psychology. The first part of the paper considers this approach from a patient's perspective, the second from the perspective of a dentist. Because the impact on the quality of care for the patient is largely mediated through the personality of the dentist, the quality of the dentist's own performance, during his/her professional relationship with the patient, is a critical ingredient. The way that this critical ingredient impacts on quality of care is considered and parallels are drawn between roles assumed in dental practice and those found in industry. The paper also considers the way in which mentoring, as a part of a professional development programme, can enhance dentists' personal skills and performance. It is an opportunity for great personal growth, with increased levels of job and life satisfaction, leading to greater levels of authentic happiness for all those involved, not least for dentists and the dental team.

    There is limited understanding of ethnic inequalities in doctor-patient communication regarding personal care plans (PCPs). This study investigated the mediating effects of positive mental wellbeing on differences in PCP-related doctor-patient communication amongst South Asian and Caucasian UK residents. Data from 10,980 respondents to the 2013 Health Survey for England was analysed using bootstrapping methods. Constructs from the WEMWBS (Warwick and Edinburgh Mental Wellbeing Scale) (Stewart-Brown, S., and K. Janmohamed. 2008. Warwick, UK) were assessed as mediators of relations between ethnicity and several doctor-patient communication variables, including PCP-related interactions; (a) had a PCP-related discussion about a long-term condition with a doctor/nurse, and (b) had this conversation within the past year, (c) agreed to a PCP with a health professional; and (d) talked to a doctor in the past 2 weeks. Bootstrapped mediation analysis (Hayes, A. F. 2013. Introduction to Mediation, Moderation, and Conditional Process Analysis: A Regression-based Approach. New York, NY: The Guilford Press) showed that three positive mind-sets mediated associations between ethnicity and doctor-patient contact, including PCP-related communication. Being able to make up one's mind (ab = -0.05; BC a CI [-0.14, 0.01]) mediated the effect of ethnicity on agreeing to a PCP, while having energy to spare (ab = 0.07; BC a CI [-0.04, 0.12]), and feeling good about oneself (ab = 0.03; BC a CI [0.01, 0.07]), mediated ethnic effects on talking to a doctor during the past fortnight. The mediating effect of reported energy persisted after controlling for medical history, perceived health, and other covariates. Ethnic disparities in doctor-patient interaction, including PCP-related communication, are partly explained by positive mental wellbeing. Gauging positive psychological moods in patients, particularly self-worth, self-perceived vigour and decisiveness, are relevant to

    Ample research suggests that social connection reliably generates positive emotions. Oxytocin, a neuropeptide implicated in social cognition and behavior, is one biological mechanism that may influence an individual's capacity to extract positive emotions from social contexts. Because variation in certain genes may indicate underlying neurobiological differences, we tested whether several SNPs in two genes related to oxytocin signaling would show effects on positive emotions that were context-specific, depending on sociality. For six weeks, a sample of mid-life adults (N=122) participated in either socially-focused loving-kindness training or mindfulness training. During this timespan they reported their positive emotions daily. Five SNPs within OXTR and CD38 were assayed, and each was tested for its individual effect on daily emotions. The hypothesized three-way interaction between time, training type, and genetic variability emerged: Individuals homozygous for the G allele of OXTR rs1042778 experienced gains in daily positive emotions from loving-kindness training, whereas individuals with the T allele did not experience gains in positive emotions with either training. These findings are among the first to show how genetic differences in oxytocin signaling may influence an individual's capacity to experience positive emotions as a result of a socially-focused intervention.

    In sub-Saharan Africa, the prevalence of depressive symptoms among people living with HIV (PLHIV) is considerably greater than that among members of the general population. It is particularly important to treat depressive symptoms among PLHIV because they have been associated with poorer HIV care-related outcomes. This study describes overall psychosocial functioning and factors associated with depressive symptoms among PLHIV attending HIV care and treatment clinics in Kenya, Namibia, and Tanzania. Eighteen HIV care and treatment clinics (six per country) enrolled approximately 200 HIV-positive patients (for a total of 3,538 participants) and collected data on patients' physical and mental well-being, medical/health status, and psychosocial functioning. Although the majority of participants did not report clinically significant depressive symptoms (72 %), 28 % reported mild to severe depressive symptoms, with 12 % reporting severe depressive symptoms. Regression models indicated that greater levels of depressive symptoms were associated with: (1) being female, (2) younger age, (3) not being completely adherent to HIV medications, (4) likely dependence on alcohol, (5) disclosure to three or more people (versus one person), (6) experiences of recent violence, (7) less social support, and (8) poorer physical functioning. Participants from Kenya and Namibia reported greater depressive symptoms than those from Tanzania. Approximately 28 % of PLHIV reported clinically significant depressive symptoms. The scale-up of care and treatment services in sub-Saharan Africa provides an opportunity to address psychosocial and mental health needs for PLHIV as part of comprehensive care.

    Instrumental music performance ranks among the most complex of learned human behaviors, requiring development of highly nuanced powers of sensory and neural discrimination, intricate motor skills, and adaptive abilities in a temporal activity. Teaching, learning and performing on the violin generally occur within musico-cultural parameters most often transmitted through aural traditions that include both verbal instruction and performance modeling. In most parts of the world, violin is taught in a manner virtually indistinguishable from that used 200 years ago. The current study uses methods from movement science to examine the "how" and "what" of left-hand position changes (shifting), a movement skill essential during violin performance. In doing so, it begins a discussion of artistic individualization in terms of anthropometry, the performer-instrument interface, and the strategic use of motor behaviors. Results based on 540 shifting samples, a case series of 6 professional-level violinists, showed that some elements of the skill were individualized in surprising ways while others were explainable by anthropometry, ergonomics and entrainment. Remarkably, results demonstrated each violinist to have developed an individualized pacing for shifts, a feature that should influence timing effects and prove foundational to aesthetic outcomes during performance. Such results underpin the potential for scientific methodologies to unravel mysteries of performance that are associated with a performer's personal artistic style.

    Sexual risk behaviour was explored and described using Social Action Theory. The sexual transmission of HIV is complex and multi-factorial. Social Action Theory provides a framework for viewing self-regulation of modifiable behaviour such as condom use. Condom use is viewed within the context of social interaction and interdependence. Cross-sectional survey. Self-report questionnaire administered to adults living with HIV/AIDS, recruited from clinics, service organizations and by active outreach, between 2010 - 2011. Having multiple sex partners with inconsistent condom use during a 3-month recall period was associated with being male, younger age, having more years of education,substance use frequency and men having sex with men being a mode of acquiring HIV. In addition, lower self-efficacy for condom use scores were associated with having multiple sex partners and inconsistent condom use. Social Action Theory provided a framework for organizing data from an international sample of seropositive persons. Interventions for sexually active, younger, HIV positive men who have sex with men, that strengthen perceived efficacy for condom use, and reduce the frequency of substance use, may contribute to reducing HIV-transmission risk. © 2016 John Wiley & Sons Ltd.

    There is increasing interest in the construct validity of higher-order domains of the Big Five personality traits. A total of 831 persons from the Swiss population completed the International Personality Item Pool and an adaptation of the Positive and Negative Affect Scales. Using Goldberg's bass-ackwards method, we found evidence for the general factor of personality (GFP) and the two meta-traits of positive emotionality (blend of low neuroticism and high extraversion) and constraint (blend of high agreeableness and conscientiousness). In association with positive affect, the explanatory power of the GFP (r = 0.43) and positive emotionality (r = 0.37) was largely superior to extraversion (r = 0.24), conscientiousness (r = 0.18), agreeableness (r = 0.09) and openness (r = 0.04), although not neuroticism (r = -0.34). In association with negative affect, neuroticism (r = 0.41), the GFP (r = -0.36) and positive emotionality (r = -0.35) were the most powerful single predictors. We conclude that the higher-order structure of personality is best explained by the meta-traits of positive emotionality and constraint, which correspond closely to the well-established superfactors of internalizing and externalizing. We further demonstrate that these have substantial criterion validity when broad positive and negative affect is the outcome of interest. These findings help to relate Big Five meta-traits to pathological personality. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available The purpose of the paper is to present the importance of locally embedded personal relationships and individuals’ networks for the rise of small and medium enterprises (SMEs’ opportunities in the internationalisation process (especially the market entry phase as well as their international operations and growth. Above all, the aim of the article is to answer the question what is influencing the actual impact of these resulting opportunities on internationalisation and growth. This paper adopts both a conceptual and empirical approach to the problem based upon a critical review of pertinent literature. Two case studies of companies from industries representing different levels of technological advancement, that is the furniture industry and IT industry, are presented. The theoretical and empirical analysis presented in the article points to the fact that relationships simultaneously facilitate opportunity recognition and themselves constitute such an opportunity. The analysis carried out as part of the case study proves that main factors determining the rise of the opportunity based on locally embedded personal relationships are trust and mutual understanding, in this way emphasising the importance of relational embeddedness. At the same time the realisation of these opportunities and therefore their impact on the internationalisation process and a company’s growth requires additional social factors (an entrepreneurial attitude as well as economic factors (such as quality and competitive prices.

It was assumed that both complementary and supplementary P-O fit and OI were positively related to WHI+ and negatively to WHI-. Materials and Methods: The study was conducted on a large sample of Polish blue and white collar workers. The subjects were interviewed by means of questionnaires measuring: supplementary and complementary dimensions of P-O fit, OI and WHI. General work ability and demographic variables were also controlled in the study, and statistical analysis of ANOVA, pairwise comparison as well as regression were performed. Results: P-O fit and OI differentiated the subjects in terms of WHI. For women supplementary fit was a significant predictor of WHI- and explained 12% of its variance, for men it was complementary fit with the number of working days per week and the level of education, which explained 22% of variance. Supplementary fit and OI explained 16% of WHI+ variance in women; OI, tenure at the main place of employment and the level of education explained 8% of WHI+ variance in men. Conclusions: It has been proven that not only are the effects of P-O fit and OI limited to the work environment but they also permeate boundaries between work and home and influence private life - good level of P-O fit and good OI play facilitating role in the positive spillover between work and home. Gender differences in the significance and predictive values of P-O fit and OI for WHI were also found. The innovative aspect of the work is the inclusion of P-O fit and OI in the range of significant predictors of work-home interaction.

  2. Cyclin G Functions as a Positive Regulator of Growth and Metabolism in Drosophila.

    2015-08-01

    Full Text Available In multicellular organisms, growth and proliferation is adjusted to nutritional conditions by a complex signaling network. The Insulin receptor/target of rapamycin (InR/TOR signaling cascade plays a pivotal role in nutrient dependent growth regulation in Drosophila and mammals alike. Here we identify Cyclin G (CycG as a regulator of growth and metabolism in Drosophila. CycG mutants have a reduced body size and weight and show signs of starvation accompanied by a disturbed fat metabolism. InR/TOR signaling activity is impaired in cycG mutants, combined with a reduced phosphorylation status of the kinase Akt1 and the downstream factors S6-kinase and eukaryotic translation initiation factor 4E binding protein (4E-BP. Moreover, the expression and accumulation of Drosophila insulin like peptides (dILPs is disturbed in cycG mutant brains. Using a reporter assay, we show that the activity of one of the first effectors of InR signaling, Phosphoinositide 3-kinase (PI3K92E, is unaffected in cycG mutants. However, the metabolic defects and weight loss in cycG mutants were rescued by overexpression of Akt1 specifically in the fat body and by mutants in widerborst (wdb, the B'-subunit of the phosphatase PP2A, known to downregulate Akt1 by dephosphorylation. Together, our data suggest that CycG acts at the level of Akt1 to regulate growth and metabolism via PP2A in Drosophila.

    Juniperus thurifera L. is an endemic conifer of the western Mediterranean Basin where it is subjected to a severe climatic stress characterized by low winter temperatures and summer drought. Given the trend of increased warming-induced drought stress in this area and the climatic sensitivity of this species, we expect a negative impact of climate change on growth and ecophysiological performance of J. thurifera in the harsh environments where it dominates. To evaluate this, we measured long- and short-term radial growth using dendrochronology, photosynthesis and water-use efficiency in males, females and juveniles in three sites in Central Spain. Climate was monitored and completed with historical records. Mean annual temperature has increased +0.2 °C per decade in the study area, and the main warming trends corresponded to spring (+0.2 °C per decade) and summer (+0.3 °C per decade). Radial growth and maximum photosynthesis peaked in spring and autumn. Positive photosynthetic rates were maintained all year long, albeit at reduced rates in winter and summer. Radial growth was enhanced by wet conditions in the previous autumn and by warm springs and high precipitation in summer of the year of tree-ring formation. Cloud cover during the summer increased growth, while cloudy winters led to impaired carbon gain and reduced growth in the long term. We argue that maintenance of carbon gain under harsh conditions (low winter temperatures and dry summer months) and plastic xylogenesis underlie J. thurifera's ability to profit from changing climatic conditions such as earlier spring onset and erratic summer rainfall. Our results highlight that not only the magnitude but also the sign of the impact of climate change on growth and persistence of Mediterranean trees is species specific.

    Linear modelling approaches detected significant gradients in organ growth and patterning across early flowers of the Arabidopsis inflorescence and uncovered evidence of new roles for gibberellin in floral development. Most flowering plants, including the genetic model Arabidopsis thaliana, produce multiple flowers in sequence from a reproductive shoot apex to form a flower spike (inflorescence). The development of individual flowers on an Arabidopsis inflorescence has typically been considered as highly stereotypical and uniform, but this assumption is contradicted by the existence of mutants with phenotypes visible in early flowers only. This phenomenon is demonstrated by mutants partially impaired in the biosynthesis of the phytohormone gibberellin (GA), in which floral organ growth is retarded in the first flowers to be produced but has recovered spontaneously by the 10th flower. We presently lack systematic data from multiple flowers across the Arabidopsis inflorescence to explain such changes. Using mutants of the GA 20-OXIDASE (GA20ox) GA biosynthesis gene family to manipulate endogenous GA levels, we investigated the dynamics of changing floral organ growth across the early Arabidopsis inflorescence (flowers 1-10). Modelling of floral organ lengths identified a significant, GA-independent gradient of increasing stamen length relative to the pistil in the wild-type inflorescence that was separable from other, GA-dependent effects. It was also found that the first flowers exhibited unstable organ patterning in contrast to later flowers and that this instability was prolonged by exogenous GA treatment. These findings indicate that the development of individual flowers is influenced by hitherto unknown factors acting across the inflorescence and also suggest novel functions for GA in floral patterning.

    The purpose of the investigation was to explore the relationship between positive or negative symptoms, social anxiety, hope, personality, and self-stigma in patients with schizophrenia spectrum disorders. 57 outpatients took part in this cross-sectional study. The structured interview M.I.N.I. International Neuropsychiatric Interview was used to confirm the diagnosis. All patients completed the Liebowitz Social Anxiety Scale, Internalized Stigma of Mental Illness Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Adult Dispositional Hope Scale, and Temperament and Character Inventory - Revised. The disorder severity was evaluated by Clinical Global Impression - Severity scale, and Positive and Negative Syndrome Scale. The patients were in a stabilized state that did not require hospitalization or modifications in the treatment. Both positive and negative symptoms of schizophrenia positively correlated with the length of the disorder, global severity of the disorder, the severity of the general and social anxiety symptoms, the severity of self-stigma, and negatively with personality traits Self-directedness and Cooperativeness. Only negative symptoms significantly positively correlated with the severity of depressive symptoms and personality trait Harm-avoidance and negatively with the hope and personality trait Persistence. Comorbidity with social phobia is associated with statistically significantly higher mean scores on the total score of schizophrenic symptomatology, negative subscale average rating, and general psychopathological items measured by PANSS. Patient with comorbid depression would experience a higher level of negative symptomatology than patients without such comorbidity.

    No studies have examined the impact of personality traits on mental health among caregivers of individuals with severe brain injury. Therefore, the purpose of the current study was to construct linear growth models to examine whether the personality traits of family members of individuals with severe brain injury could predict the trajectories of their own mental health-related quality of life (HRQoL), anxiety, and depression beginning in a neurointensive care unit through 1 year after injury. Danish family members of individuals with severe brain injury (n = 52) completed the Short Form-36 assessing mental HRQoL (vitality, social functioning, role limitations-emotional, mental health), anxiety, and depression across 5 time points during the 1st year after injury. The measure of personality was administered 3 months after the patients' discharge. All mental HRQoL, anxiety, and depression variables improved significantly over time. Caregivers who were less neurotic and less conscientious had higher vitality, social functioning, and mental health over time, whereas caregivers who were more agreeable had higher social functioning over time. Caregivers with lower neuroticism had lower anxiety and depression over time, as well as a more accelerated decrease in anxiety and depression. Caregivers' personality traits were strongly associated over time with mental HRQoL, anxiety, and depression, with neuroticism being especially important for trajectories of anxiety and depression. These results suggest that personality assessments for caregivers of individuals with severe brain injury could help identify those most at risk for poor mental health over the course of rehabilitation.

    Breast cancer is a heterogeneous disease. Thanks to extensive efforts from research scientists and clinicians, treatment for breast cancer has advanced into the era of targeted medicine. With the use of several well-established biomarkers, such as hormone receptors (HRs) (i.e., estrogen receptor [ER] and progesterone receptor [PgR]) and human epidermal growth factor receptor-2 (HER2), breast cancer patients can be categorized into multiple subgroups with specific targeted treatment strategies. Although therapeutic strategies for HR-positive (HR+) HER2-negative (HER2-) breast cancer and HR-negative (HR-) HER2-positive (HER2+) breast cancer are well-defined, HR+ HER2+ breast cancer is still an overlooked subgroup without tailored therapeutic options. In this review, we have summarized the molecular characteristics, etiology, preclinical tools and therapeutic options for HR+ HER2+ breast cancer. We hope to raise the attention of both the research and the medical community on HR+ HER2+ breast cancer, and to advance patient care for this subtype of disease. Copyright © 2015 Elsevier Ltd.

    1981-01-01

    For an estimation of regional brain perfusion after intravenous injection of 99m Tc-pertechneate, the author followed the registration of the initial perfusion input in ventrosagittal or lateral setting of the scintillation camera in 74 patients. The time-activity characteristics were obtained across standardized regions, the mode of evaluation was applied as mentioned. A mean value of 49.1 for the perfusion of the right hemisphere was determined, for the left one it was 49.7 ml/100g/min. The regional mean values lay between 44.4 (parietal region) and 39.6 (temporal region) ml/100g for the lateral position. Thirtyone patients with intracronical growths were examined either directly before surgery or one year before it. In 22 of the patients examined before surgery a significantly lower regional perfusion could be computet for the ventral position; whereas the lateral perfusion values corresponded to values of healthy persons. The orienting calculation of regional brain perfusion at longer intervals after tumor extirpation did not show a significant difference to the clinically-neurologically inconspicuous patient collective in lateral exposure position normal patients. In 12 cases the calculation of the regional perfusion followed directly via the tumour. On an average, the values were about 8.2 ml/100g/min lower than in normal cases. (orig./MG) [de

    We have previously shown that fat-free mass (FFM) at birth is associated with height at 2 y of age in Ethiopian children. However, to our knowledge, the relation between changes in body composition during early infancy and later linear growth has not been studied. This study examined the associations of early infancy fat mass (FM) and FFM accretion with linear growth from 1 to 5 y of age in Ethiopian children. In the infant Anthropometry and Body Composition (iABC) study, a prospective cohort study was carried out in children in Jimma, Ethiopia, followed from birth to 5 y of age. FM and FFM were measured ≤6 times from birth to 6 mo by using air-displacement plethysmography. Linear mixed-effects models were used to identify associations between standardized FM and FFM accretion rates during early infancy and linear growth from 1 to 5 y of age. Standardized accretion rates were obtained by dividing FM and FFM accretion by their respective SD. FFM accretion from 0 to 6 mo of age was positively associated with length at 1 y (β = 0.64; 95% CI: 0.19, 1.09; P = 0.005) and linear growth from 1 to 5 y (β = 0.63; 95% CI: 0.19, 1.07; P = 0.005). The strongest association with FFM accretion was observed at 1 y. The association with linear growth from 1 to 5 y was mainly engendered by the 1-y association. FM accretion from 0 to 4 mo was positively associated with linear growth from 1 to 5 y (β = 0.45; 95% CI: 0.02, 0.88; P = 0.038) in the fully adjusted model. In Ethiopian children, FFM accretion was associated with linear growth at 1 y and no clear additional longitudinal effect from 1 to 5 y was observed. FM accretion showed a weak association from 1 to 5 y. This trial was registered at www.controlled-trials.com as ISRCTN46718296.

    Full Text Available Economic and business challenges in the new millennium have shaped the manner cooperative movement in Malaysia charts its future outlook. After almost 82 years, a national policy was launched by the Government on January 2004 to assist in the comprehensive development of the cooperative movement. The National CooperativePolicy (NCP will ensure that the huge resources of the cooperatives can be harnessed to generate and contribute to the economic growth of the country. However, in the light of many issues such as weak structure and the absence of good corporate governance in some cooperatives, the present Cooperative Act 1993 is being reviewed and several new provisions would be added to increase supervision, monitoring and enforcement against existing cooperatives in alaysia. It is quite imperative that by regulating the operation of cooperatives will require also the managing of intellectual and human capital assets that exist in the movement. Through establishing a framework and terms of reference such that fundamental elements of knowledge management can be instilled areprerequisites to developing innovativeness in this growing economic sector. The sharing of knowledge among the cooperatives will eventually produce better and more educated human resources that are able to experience greater control over the works and the administration of their quality working life. Structural analysis of the cooperative movement indicates the significant influence of knowledge management in sustaining its future growth given the timely introduction of the NCP. Thus, measures taken to underline this influence will also be addressed to represent the cooperative movement's readiness to face economic and business challenges in Malaysia.

    1980-01-01

    Age effect on gas exchange was studied in the recumbent and orthostatic positions and under physical load. In the case of the older age group and for normal as compared with hypersthenic persons, oxygen consumption during rest and during moderate physical overload diminishes. When the vertical position is assumed oxygen consumption in persons of various age groups is distinctly increased, particularly in the elderly group. There is a reduction in the amount of oxygen consumption, oxygen pulse, recovery coefficient, and work efficiency under moderate overload. In persons over 50, physical labor induces a large oxygen requirement and a sharp rise in the level of lactic acid and the blood's lactate/pyruvate ratio. No distinct difference was noted in the amount of oxygen consumed during rest and during physical overload in men and women of the same physical development and age.

    Full Text Available Suitcase trading which is defined as a purchasing process of merchandises in a country that is implemented by travelers (nonresidents to sell those merchandises in their own country; it has started to take place in balance of payments of Turkey since 1996. After the collapse of USSR in 1991 Turkey became a net exporter in suitcase trading so the country reached significant figures occasionally. In this paper the position of suitcase trading in Turkey’s foreign trade is analyzed in consideration of statistical indicators. According to the findings acquired from the study, suitcase trading is a significant variable for Turkey to have currency and to close foreign deficits. Suitcase trading and growth connection is also analyzed by econometric method which is co-integration test and the result is affirmative. And also it is found that this connection is unilateral causation from growth towards suitcase trading according to the findings of Granger causality test

    Full Text Available The aim is to study the effectiveness of different physical training for the relatively healthy students. The study involved 1004 students. The directions of development of the students' positive personal qualities. Found that the positive development of personality of students observed mostly on the first and third year than in the second. Could not find significant differences between the growth estimates of development of personality traits of students in classes in the sample program and the program specializations. Found that the rate of development of students' personality traits minor: the average growth estimates for core positive personal qualities for 3 years does not exceed 10% of the maximum possible level. Recommended in the classroom more emphasis on developing positive personality traits. It is shown that special attention should be paid to the development of emotional stability of students and their tolerance towards other people.

    Laron, Zvi

    2004-03-01

    Clinical and laboratory investigations starting in 1958 of a group of dwarfed children resembling isolated GH deficiency but who had very high serum levels of GH led to the description of the syndrome of primary GH resistance or insensitivity (Laron syndrome) and subsequently to the discovery of its molecular defects residing in the GH receptor and leading to an inability of IGF-I generation. With the biosynthesis of IGF-I in 1986, therapeutic trials started. Continuously more and more patients are being diagnosed in many parts of the world with a variety of molecular defects. This syndrome proved to be a unique model that enables the study of the consequences of GH receptor defects, the physiopathology of GH-IGF-I disruption, and comparison of the GH-independent IGF-I effects. This review presents the personal experience gained from the study follow-up and treatment of the 60 patients followed up for many years in the Israeli cohort.

    Screening can increase detection of clinically relevant depressive symptoms, but screen-positive persons are not necessarily willing to accept a subsequent unsolicited treatment offer. Our objective was to explore limiting and motivating factors in accepting an offer to join a "coping with depression" course, and perceived needs among persons aged ≥75 years who screened positive for depressive symptoms in general practice. In a randomized controlled trial, in which 101 persons who had screened positive for depressive symptoms were offered a "coping with depression" course, a sample of 23 persons were interviewed, of whom five (22%) accepted the treatment offer. Interview transcripts were coded independently by two researchers. All five individuals who accepted a place on the course felt depressed and/or lonely and had positive expectations about the course. The main reasons for declining to join the course were: not feeling depressed, or having negative thoughts about the course effect, concerns about group participation, or about being too old to change and learn new things. Although perceived needs to relieve depressive symptoms largely matched the elements of the course, most of those who had been screened were not (yet) prepared to accept an intervention offer. Many expressed the need to discuss this treatment decision with their general practitioner. Although the unsolicited treatment offer closely matched the perceived needs of people screening positive for depressive symptoms, only those who combined feelings of being depressed or lonely with positive expectations about the offered course accepted it. Treatment should perhaps be more individually tailored to the patient's motivational stage towards change, a process in which general practitioners can play an important role.

    The contents of two bioactive compounds (polyphenols and flavonoids) and their antioxidant and enzyme activities were determined in the leaves of six lettuce (Latuca sativa L.) cultivars subjected to 4 different day/night temperatures for 6 weeks. The total polyphenol and anthocyanin contents and the corresponding antioxidant activities were the highest at 13/10°C and 20/13°C, followed by 25/20°C and 30/25°C. The enzymatic activities of polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL) were also the highest at low day/night temperatures, but the peroxidase (POD) activity was decreased at low day/night temperatures and increased at high day/night temperatures. The most significant positive correlation existed between anthocyanin content and PPO activity, total polyphenols and their antioxidant activities. The results showed that at relatively low temperatures, lettuce plants have a high antioxidant and enzymatic status. These results provide additional information for the lettuce growers.

    In a market undergoing constant evolution, the production of chicken meat that consumers would perceive as "natural" and "animal friendly" is crucial. The use of probiotics in rurally reared chickens could represent a major opportunity to achieve mutual benefit for both the industry and consumers. A total of 264 male Kabir chicks were randomly distributed to one of 2 dietary treatments: the L group received a commercial feed supplemented with 2.0 g/100 kg of Lactobacillus acidophilus D2/CSL, while the C group received the same basal diet without the additive. To assess the effects of probiotic supplementation in the chickens' diet, productive performance was evaluated at d 21 and 42, whereas microbiological analyses of the intestinal content and intestinal histology and morphometry were performed at the end of the trial (d 42). At d 21 and 42, L birds showed better (P D2/CSL (CECT 4529) in rurally reared chicken breeds with positive effects on performance and gut health.

    This study examines the role of coping strategies related to positive reappraisal versus other cognitive strategies (deliberate rumination) as mediators between life impact and posttraumatic growth in survivors of the military dictatorship in Chile between 1973 and 1990 (tortured political prisoners and family members of political prisoners executed and missing). Survey data from 251 political violence survivors were analyzed using the SPSS PROCESS macro for bootstrapping indirect effects (Hayes, 2013). Results indicated that positive reappraisal (or reframing) coping mediated the relationship between life impact and posttraumatic growth. A serial multiple mediation model indicates that in the life impact to growth moderation process, rumination must be followed by positive reappraisal to drive this growth. These findings suggest that positive reappraisal of the traumatic experience is essential to achieve growth reports. Implications of these more complex relations are discussed for both counseling interventions and further research. © The Author(s) 2016.

    Notch signaling plays a key role in cell-fate determination and differentiation in different organisms and cell types. Several reports suggest that Notch signaling may be involved in neoplastic transformation. However, in primary keratinocytes, Notch1 can function as a tumor suppressor. Similarly, in HPV-positive cervical cancer cells, constitutively active Notch1 signaling was found to cause growth suppression. Activated Notch1 in these cells represses viral E6/E7 expression through AP-1 down-modulation, resulting in increased p53 expression and a block of pRb hyperphosphorylation. Here we show that in cervical cancer cell lines in which Notch1 ability to repress AP-1 activity is impaired, Notch1-enforced expression elicits an alternative pathway leading to growth arrest. Indeed, activated Notch1 signaling suppresses activity of the helix-loop-helix transcription factor E47, via ERK1/2 activation, resulting in inhibition of cell cycle progression. Moreover, we found that RBP-Jκ-dependent Notch signaling is specifically repressed in cervical cancer cells and this repression could provide one such mechanism that needs to be activated for cervical carcinogenesis. Finally, we show that inhibition of endogenous Notch1 signaling, although results in a proliferative advantage, sensitizes cervical cancer cell lines to drug-induced apoptosis. Together, our results provide novel molecular insights into Notch1-dependent growth inhibitory effects, counteracting the transforming potential of HPV

    The research was conducted with the aim to establish the structure and the differences of morphological features and personality traits between different age groups of female cadet handball players grouped by their playing quality and playing positions. Further on, the research was done on 70 handball players aged 15, 31 on average, who were grouped according to their positions on goalkeepers, outside players, wings and pivots. Furthermore, according to the quality of playing, they were divided in two quality groups of players, those from the wider cadet national team, thus characterised as top female players in Croatia, and those who had never been invited into the cadet national team and thus can be referred to as low-quality, i.e. average female handball players. The structure of predictor variables has indicated the existence of general morphological factor assessing the players' constitution and two personality features factors - neuroticism and extraversion. The variance analysis showed no statistically significant differences of somatotype variables with relation to quality and playing position. By observing basic personality traits, a statistically significant difference was confirmed only in introversion-extraversion with a lower score in goalkeepers than in other positions, which indicates a higher level of introversion in this playing position. Such result was expected since this particular position abounds in specific tasks and demands in the game in relation to all other playing positions. Further on, it has been concluded that the selection of players must not be based only on the stated physical and psychological characteristics, but on relevant anthropological complexes determining performance and sport achievement.

    To explore the association between obsessive-compulsive personality disorder (OCPD) and suicidal behavior. Subjects referred for a psychiatric consultation were evaluated with structured interviews for mood and personality disorders (the Structured Clinical Interview for DSM-III-R and the Structured Clinical Interview for DSM-III-R Axis II Disorders), a history of suicidal behavior, and levels of coping. A total of 311 subjects were investigated using a 3-group design to test the association between OCPD and suicidal behavior, controlling for the presence of depression. Subjects with OCPD and a history of depression were compared to depressed subjects without any Axis II diagnosis and to subjects without depression or personality disorders. The study was conducted at Verdun Community Psychiatric Clinic, Douglas Hospital, McGill University, in Montreal, Quebec, Canada, and subjects were recruited from 2003 until 2005. Subjects in the comorbid OCPD-depression group presented increased current and lifetime suicide ideation compared to the groups with depression alone or without depression or personality disorders (P = .004); they also had increased history of suicide attempts (P = .04), which were often multiple attempts (P = .01). They also scored lower on the Reasons for Living Inventory (RFL) and the Death Anxiety Questionnaire. Interestingly, comorbid OCPD-depression patients differed from patients with depression alone on the Moral Objections items of the RFL, on which individuals with OCPD-depression scored lowest. Limitations of this study were its cross-sectional design, retrospective sample, and limited generalizability to the population at large. Obsessive-compulsive personality disorder is a factor increasing risk for nonfatal suicidal behavior independently of risk conferred by depressive disorders.

    Higgins, Geoff S; Krause, Mechthild; McKenna, W Gillies; Baumann, Michael

    Molecular biomarkers are currently evaluated in preclinical and clinical studies in order to establish predictors for treatment decisions in radiation oncology. The receptor tyrosine kinases (RTK) are described in the following text. Among them, the most data are available for the epidermal growth factor receptor (EGFR) that plays a major role for prognosis of patients after radiotherapy, but seems also to be involved in mechanisms of radioresistance, specifically in repopulation of tumour cells between radiotherapy fractions. Monoclonal antibodies against the EGFR improve locoregional tumour control and survival when applied during radiotherapy, however, the effects are heterogeneous and biomarkers for patient selection are warranted. Also other RTK´s such as c-Met and IGF-1R seem to play important roles in tumour radioresistance. Beside the potential to select patients for molecular targeting approaches combined with radiotherapy, studies are also needed to evluate radiotherapy adaptation approaches for selected patients, i.e. adaptation of radiation dose, or, more sophisticated, of target volumes.

    Full Text Available BACKGROUND: Human immunodeficiency virus (HIV infection and its treatment cause a range of hematological abnormalities. Anemia is one of the commonly observed hematologic manifestations in HIV positive persons and it has multifactorial origin. OBJECTIVE: We aimed to determine the prevalence and risk factors of anemia in highly active antiretroviral therapy (HAART naïve and HAART experienced HIV positive persons. METHODS: A facility-based comparative cross sectional study was conducted in Jimma University Specialized Hospital from February 1 to March 30, 2012. A total of 234 HIV positive persons, 117 HAART naïve and 117 HAART experienced, were enrolled in this study. Blood and stool specimens were collected from each participant. Blood specimens were examined for complete blood count, CD4 count and blood film for malaria hemoparasite; whereas stool specimens were checked for ova of intestinal parasites. Socio-demographic characteristics and clinical data of the participants were collected using pre-tested questionnaire. Statistical analysis of the data (Chi-square, student's t-test, logistic regression was done using SPSS V-16. RESULTS: The overall prevalence of anemia was 23.1%. The prevalence of anemia in HAART naïve and HAART experienced persons was 29.9% and 16.2%, respectively (P = 0.014. Presence of opportunistic infections (P = 0.004, 95% CI = 1.69-15.46, CD4 count <200 cells/µl (P = 0.001, 95% CI = 2.57-36.89 and rural residence (P = 0.03, 95% CI = 1.12-10.39 were found to be predictors of anemia for HAART naïve participants. On the other hand, HAART regimen (ZDV/3TC/NVP (P = 0.019, 95% CI = 0.01-1.24 and the duration of HAART (P = 0.007, 95% CI = 0.003-0.40.24 were found to be predictors of anemia for HAART experienced groups. CONCLUSION: The prevalence of anemia in HAART naïve persons was higher than HAART experienced persons. Risk factors for anemia in HAART naïve and HAART experienced HIV positive persons were different. Hence

    We evaluated associations between personal and clinical social support and non-adherence to adjuvant endocrine therapy (AET) in a large, Northern California breast cancer (BC) cohort from an integrated healthcare network. This study included 3382 women from the Pathways Study diagnosed from 2005 to 2013 with stages I-III hormone receptor-positive BC and who responded to the Medical Outcomes Study Social Support and Interpersonal Processes of Care surveys, approximately 2 months post-diagnosis. We used logistic regression to evaluate associations between tertiles of social support and non-initiation (social support (P trend = 0.02). Women with moderate (HR 1.20, 95% CI 0.99-1.45) or low (HR 1.32, 95% CI 1.09-1.60) personal social support were also more likely to discontinue treatment (P trend = 0.01). Furthermore, women with moderate (HR 1.25, 95% CI 1.02-1.53) or low (HR 1.38, 95% CI 1.12-1.70) personal social support had higher non-adherence (P trend = 0.007). Associations with clinical social support and outcomes were similar. Notably, high clinical social support mitigated the risk of discontinuation when patients' personal support was moderate or low (P value = 0.04). Women with low personal or clinical social support had higher AET non-adherence. Clinician teams may need to fill support gaps that compromise treatment adherence.

    B vitamins have beneficial roles in mental health functional impairments; however, research on the role of B vitamins in depression among HIV-infected persons is limited. This study assessed the association between dietary B vitamin intake and depressive symptoms in a cohort of HIV-infected persons. A cross-sectional survey was conducted among 314 HIV-infected persons (180 men and 134 women) aged 18 to 60 y residing in the Kathmandu, Nepal. The Beck Depression Inventory-I was used to measure depression, with a cutoff score of 20 or higher. Dietary intake was assessed using two nonconsecutive 24-h dietary recalls. The relationships between B vitamins and depressive symptoms were assessed using multiple logistic regression analysis. Twenty-six percent participants (men: 23%; women: 29%) were depressed. More than two thirds of participants' B vitamins intake were below the estimated average requirements (EAR) level. Low intake of riboflavin was associated with an increased risk of depression in women but not in men. Multivariate OR (95% CI) for depression in the first, second, and third tertiles of riboflavin in total participants were 1 (reference), 0.87 (0.46-1.64), and 0.49 (0.24-0.98), respectively (p for trend=0.048) and in women were 1 (reference), 0.94 (0.36-2.40), and 0.23 (0.07-0.77), respectively (p for trend=0.020). No clear associations were seen between other B vitamins and depressive symptoms in either sex. Low intake of riboflavin was independently associated with an increased risk of depressive symptoms in all participants and in HIV-infected women. Further prospective studies are warranted to confirm the role of vitamin B vitamins in depressive symptoms among HIV-infected persons.

    The current research investigated the effects of negative as compared to positive person-based political campaigns on explicit and implicit evaluations of the involved candidates. Participants were presented with two political candidates and statements that one of them ostensibly said during the last political campaign. For half of the participants, the campaign included positive remarks about the source of the statement (positive campaign); for the remaining half, the campaign included negative remarks about the opponent (negative campaign). Afterwards, participants completed measures of explicit and implicit evaluations of both candidates. Results indicate that explicit evaluations of the source, but not the opponent, were less favourable after negative as compared to positive campaigns. In contrast, implicit evaluations were less favourable for both candidates after negative campaigns. The results are discussed in terms of associative and propositional processes, highlighting the importance of associative processes in political decision making.

  13. Human tumor cells induce angiogenesis through positive feedback between CD147 and insulin-like growth factor-I.

    Directory of Open Access Journals (Sweden)

    Yanke Chen

    Full Text Available Tumor angiogenesis is a complex process based upon a sequence of interactions between tumor cells and endothelial cells. Previous studies have shown that CD147 was correlated with tumor angiogenesis through increasing tumor cell secretion of vascular endothelial growth factor (VEGF and matrix metalloproteinases (MMPs. In this study, we made a three-dimensional (3D tumor angiogenesis model using a co-culture system of human hepatocellular carcinoma cells SMMC-7721 and humanumbilical vein endothelial cells (HUVECs in vitro. We found that CD147-expressing cancer cells could promote HUVECs to form net-like structures resembling the neo-vasculature, whereas the ability of proliferation, migration and tube formation of HUVECs was significantly decreased in tumor conditioned medium (TCM of SMMC-7721 cells transfected with specific CD147-siRNA. Furthermore, by assaying the change of pro-angiogenic factors in TCM, we found that the inhibition of CD147 expression led to significant decrease of VEGF and insulin-like growth factor-I (IGF-I secretion. Interestingly, we also found that IGF-I up-regulated the expression of CD147 in both tumor cells and HUVECs. These findings suggest that there is a positive feedback between CD147 and IGF-I at the tumor-endothelial interface and CD147 initiates the formation of an angiogenesis niche.

    Human estrogen receptor α (ERα) is a nuclear transcription factor that is a major therapeutic target in breast cancer. The transcriptional activity of ERα is regulated by certain estrogen-receptor modulators. Hispolon, isolated from Phellinus linteus, a traditional medicinal mushroom called Sanghwang in Korea, has been used to treat various pathologies, such as inflammation, gastroenteric disorders, lymphatic diseases, and cancers. In this latter context, Hispolon has been reported to exhibit therapeutic efficacy against various cancer cells, including melanoma, leukemia, hepatocarcinoma, bladder cancer, and gastric cancer cells. However, ERα regulation by Hispolon has not been reported. In this study, we investigated the effects of Hispolon on the growth of breast cancer cells. We found that Hispolon decreased expression of ERα at both mRNA and the protein levels in MCF7 and T47D human breast cancer cells. Luciferase reporter assays showed that Hispolon decreased the transcriptional activity of ERα. Hispolon treatment also inhibited expression of the ERα target gene pS2. We propose that Hispolon, an anticancer drug extracted from natural sources, inhibits cell growth through modulation of ERα in estrogen-positive breast cancer cells and is a candidate for use in human breast cancer chemotherapy. - Highlights: • Hispolon decreased ERα expression at both mRNA and protein levels. • Hispolon decreased ERα transcriptional activity. • Hispolon treatment inhibited expression of ERα target gene pS2. • Shikonin is a candidate chemotherapeutic target in the treatment of human breast cancer

    2015-01-01

    There are wide spread bacterial contamination issues on various paper products, such as paper towels hanging in sink splash zones or those used to clean surfaces, filter papers used in water and air purifying systems, and wrappings used in the food industry; such contamination may lead to the potential spread of bacteria and consequent severe health concerns. In this study, selenium nanoparticles were coated on normal paper towel surfaces through a quick precipitation method, introducing antibacterial properties to the paper towels in a healthy way. Their effectiveness at preventing biofilm formation was tested in bacterial assays involving Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus epidermidis. The results showed significant and continuous bacteria inhibition with about a 90% reduction from 24 to 72 hours for gram-positive bacteria including S. aureus and S. epidermidis. The selenium coated paper towels also showed significant inhibition of gram-negative bacteria like P. aeruginosa and E. coli growth at about 57% and 84%, respectively, after 72 hours of treatment. Therefore, this study established a promising selenium-based antibacterial strategy to prevent bacterial growth on paper products, which may lead to the avoidance of bacteria spreading and consequent severe health concerns.

    Background Chronic illness is a risk factor for low self-esteem, and the research literature needs to include more studies of self-esteem and its development in chronic illness groups using longitudinal and comparative designs. The aim of this study was to explore the trajectories of self-esteem and of positive and negative affect in persons with morbid obesity and in persons with chronic obstructive pulmonary disease (COPD). Methods Patient education course attendants in Norway having morbid obesity (n=139) or COPD (n=97) participated in the study. Data concerning self-esteem, positive and negative affect, and sociodemographic background were collected at the start and at the end of the patient education, with subsequent follow-ups at 3, 6, and 12 months. Data were analyzed using linear mixed models for repeated measures. Results Taking all measurements into account, our data revealed a statistically significant increase in self-esteem for participants with morbid obesity but not for those with COPD. There were no significant differences in levels of negative and positive affect between the two groups, and the time-trajectories were also similar. However, participants in both groups achieved lower levels of negative affect for all the successive measurement points. Conclusion An increase in self-esteem during the first year after the patient education course was observed for persons with morbid obesity, but not for persons with COPD. Initial higher levels of self-esteem in the participants with COPD may indicate that they are less troubled with low self-esteem than people with morbid obesity are. The pattern of reduced negative affect for both groups during follow-up is promising. PMID:27574438

    Objective: Plants absorb radioactive elements from phosphate fertilizers, and also from naturally occurring radiation in the soil, air and water. It has long been known that low doses of ionizing radiation evoke stimulatory effects in a wide variety of living organisms. However, as far as we know, there is no published report on the bio-positive effects of diagnostic doses of X-rays on plant growth. The aim of this study was to evaluate the bio-effects of low doses of diagnostic X-rays on growth rate of Phaseolus vulgaris (Pinto) plants. Materials and Methods: Before cultivation, Phaseolus vulgaris (Pinto) seeds were soaked in tap water for 2 days followed by another 2 days of covering under a wet cloth. Four hundred newly cultivated seeds were randomly divided into two groups of 200 plants each. In this experiment, two seeds were cultivated in each dish (100 dishes for irradiation group and 100 for sham-irradiation group). Fifteen days after starting cultivation, newly grown plants were irradiated with X-rays. Plants were exposed to a single dose of X-ray (80 kVp, 80 mAs) for 6 days. On day 29, plants were pulled out from the ' soil. Length of plant stem, length of root, number of leaves and plant weight were measured. Results: The stem length in irradiated and sham-irradiated plants was 296.5{+-}13.57 and 223.96{+-}15.02 mm respectively. This difference was statistically significant (P<0.001). Although the number of leaves in irradiated plants was higher than that of sham-irradiated plants (7.05{+-}0.18 and 6.74{+-}0.19 respectively), the difference was not statistically significant. The stem diameter in irradiated and sham-irradiated plants were 3.52{+-}0.12 and 3.35{+-}0.09 mm respectively, but the difference again was not statistically significant (P<0.00 1). Plant weight in irradiated samples was less than that of non-irradiated plants but it was not statistically significant. Conclusions: The overall results indicate that diagnostic doses of X-rays can

    Organisms in the environment are exposed to a number of pollutants from different compound groups. In addition to the classic pollutants like the polychlorinated biphenyls, polyaromatic hydrocarbons (PAHs), alkylphenols, biocides, etc. other compound groups of concern are constantly emerging. Pharmaceuticals and personal care products (PPCPs) can be expected to co-occur with other organic contaminants like biocides, PAHs and alkylphenols in areas affected by wastewater, industrial effluents and intensive recreational activity. In this study, representatives from these four different compound groups were tested individually and in mixtures in a growth inhibition assay with the marine algae Skeletonema pseudocostatum (formerly Skeletonema costatum) to determine whether the combined effects could be predicted by models for additive effects; the concentration addition (CA) and independent action (IA) prediction model. The eleven tested compounds reduced the growth of S. pseudocostatum in the microplate test in a concentration-dependent manner. The order of toxicity of these chemicals were irgarol>fluoxetine>diuron>benzo(a)pyrene>thioguanine>triclosan>propranolol>benzophenone 3>cetrimonium bromide>4-tert-octylphenol>endosulfan. Several binary mixtures and a mixture of eight compounds from the four different compound groups were tested. All tested mixtures were additive as model deviation ratios, the deviation between experimental and predicted effect concentrations, were within a factor of 2 from one or both prediction models (e.g. CA and IA). Interestingly, a concentration dependent shift from IA to CA, potentially due to activation of similar toxicity pathways at higher concentrations, was observed for the mixture of eight compounds. The combined effects of the multi-compound mixture were clearly additive and it should therefore be expected that PPCPs, biocides, PAHs and alkylphenols will collectively contribute to the risk in areas contaminated by such complex

    We describe our experience with a new system of patient-specific template called Personal Fit(®), which is unique in shoulder surgery and used in combination with Duocentric(®) prosthesis. The reverse prosthesis's concept is the invention of Paul Grammont, developed with Grammont's team of Dijon University as from 1981, which led to the first reversed total shoulder prosthesis called Trumpet in 1985. The Duocentric(®) prosthesis developed in 2001 is the third-generation prosthesis, coming from the Trumpet and the second-generation prosthesis Delta(®) (DePuy). This prosthesis provides a novel solution to the notching problem with an inferior overhang integrated onto the glenoid baseplate. Personal Fit(®) system is based on reconstructing the shoulder joint bones in three dimensions using CT scan data, placing a landmark on the scapula and locating points on the glenoid and humerus. That will be used as a reference for the patient-specific templates. We study the glenoid position planned with Personal Fit(®) software relative to native glenoid position in 30 cases. On average, the difference between the planned retroversion (or anteversion in one case) and native retroversion was 8.6°.

    The relationship between housing and HIV infection is complex. On one hand, poor housing arrangements may affect the health of persons living with HIV/AIDS (PLWHAs). On the other hand, PLWHAs may be more likely to live in substandard homes because of their health. We used qualitative in-depth individual interviews of 38 PLWHAs attending voluntary counseling services at two government hospitals in the Lower Manya Krobo District (LMKD) in the Eastern region of Ghana to examine their housing and health outcomes. Results show that the majority of PLWHAs lived in homes that lacked basic amenities, were overcrowded, had structural deficiencies, and were noisy and dirty. They suffered from poor housing conditions mainly because of their HIV serostatus, as this affected their ability to finance adequate homes, while HIV-related stigmatization led to eviction from either family homes or rented facilities.

    Given high rates of trauma in people living with HIV (PLH) and the health benefits of posttraumatic growth (PTG), understanding how to foster PTG in PLH exposed to trauma could be of interest to clinical psychologists working with this population. The current study examined factors theoretically related to development of PTG in PLH, namely HIV-related stigma, disclosure of HIV status, and emotional support. A sample of 334 HIV-positive adults answered a battery of self-report questionnaires. HIV-related stigma, disclosure to sexual partners, and emotional support were significant predictors of PTG: stigma was associated with lower PTG, whereas disclosure and emotional support were associated with higher PTG. Disclosure and emotional support remained significantly associated with PTG in the model including demographic factors and stigma. These findings highlight the need for development of interventions that can aid PLH in disclosing their HIV status to sexual partners and increasing available social support.

  10. Insights into secondary growth in perennial plants: its unequal spatial and temporal dynamics in the apple (Malus domestica) is driven by architectural position and fruit load.

    Secondary growth is a main physiological sink. However, the hierarchy between the processes which compete with secondary growth is still a matter of debate, especially on fruit trees where fruit weight dramatically increases with time. It was hypothesized that tree architecture, here mediated by branch age, is likely to have a major effect on the dynamics of secondary growth within a growing season. Three variables were monitored on 6-year-old 'Golden Delicious' apple trees from flowering time to harvest: primary shoot growth, fruit volume, and cross-section area of branch portions of consecutive ages. Analyses were done through an ANOVA-type analysis in a linear mixed model framework. Secondary growth exhibited three consecutive phases characterized by unequal relative area increment over the season. The age of the branch had the strongest effect, with the highest and lowest relative area increment for the current-year shoots and the trunk, respectively. The growth phase had a lower effect, with a shift of secondary growth through the season from leafy shoots towards older branch portions. Eventually, fruit load had an effect on secondary growth mainly after primary growth had ceased. The results support the idea that relationships between production of photosynthates and allocation depend on both primary growth and branch architectural position. Fruit load mainly interacted with secondary growth later in the season, especially on old branch portions.

Both viral oncogenes are therefore regarded as ideal therapeutic targets. In the hope of developing a gene-specific therapy for HPV-related cancer, we established CRISPR/Cas9 targeting promoter of HPV 16 E6/E7 and targeting E6, E7 transcript, transduced the CRISPR/Cas9 into cervical HPV-16-positive cell line SiHa. The results showed that CRISPR/Cas9 targeting promoter, as well as targeting E6 and E7 resulted in accumulation of p53 and p21 protein, and consequently remarkably reduced the abilities of proliferation of cervical cancer cells in vitro. Then we inoculated subcutaneously cells into nude mice to establish the transplanted tumor animal models, and found dramatically inhibited tumorigenesis and growth of mice incubated by cells with CRISPR/Cas9 targeting (promoter+E6+E7)-transcript. Our results may provide evidence for application of CRISPR/Cas9 targeting HR-HPV key oncogenes, as a new treatment strategy, in cervical and other HPV-associated cancer therapy

    The research examined the role of mental health care providers' perceptions of their professional relationships with consumers in understanding their reports of agency recovery-oriented services and their own sense of job satisfaction and personal growth. Multidisciplinary community mental health care providers (N = 105) responded to an online self-report questionnaire. Providers' reports of higher levels of working alliance and greater provider directiveness in working with consumers was significantly related to providers' reports of higher levels of agency recovery-orientation and higher levels of personal growth. Providers' reports of working alliance accounted for the largest proportion of variance in providers' reports of job satisfaction. Mental health providers' perceptions of relationships with consumers are central to understanding providers' views of agency recovery-orientation and sense of professional and personal well-being.

    Significant numbers of younger persons with stroke should be given the opportunity to return to work. The aim of this study was to investigate factors of importance for return to work among persons after first ever stroke, in the age range 18-55 years. A questionnaire was sent to all persons who had experienced a first ever stroke, 18-55 years of age, registered in the Swedish national quality register for stroke care, Riks-Stroke. Of the 1068 who answered the questionnaire, 855 (539 men and 316 women) were in paid employment before their stroke, and were included in this study. Sixty-five percent returned to work and, of these, an equal proportion were men and women. Significant factors associated with return to work were the perceived importance of work (odds ratio (OR) 5.10), not perceiving themselves as a burden on others (OR 3.33), support from others for return to work (OR 3.66), retaining the ability to run a short distance (OR 2.77), and higher socioeconomic codes (OR 2.12). A negative association was found between those rehabilitated in wards intended for younger persons and return to work (OR 0.37). External support from others, and positive attitudes towards return to work, were factors associated with successful return to work after stroke. Contrary to what was expected, independence in personal activities of daily living and cognitive factors were not associated with return to work to the same extent as persistent higher level of physical functions, such as ability to run a short distance.

    Women with human epidermal growth factor receptor 2 (HER2)-positive breast cancer are candidates for treatment with the anti-HER2 antibody trastuzumab. Assessment of HER2 status in recurrent disease is usually made by core needle biopsy of a single lesion, which may not represent the larger tumor mass or other sites of disease. Our long-range goal is to develop PET of radiolabeled trastuzumab for systemically assessing tumor HER2 expression and identifying appropriate use of anti-HER2 therapies. The purpose of this study was to evaluate PET/CT of (64)Cu-DOTA-trastuzumab for detecting and measuring tumor uptake of trastuzumab in patients with HER2-positive metastatic breast cancer. Eight women with biopsy-confirmed HER2-positive metastatic breast cancer and no anti-HER2 therapy for 4 mo or longer underwent complete staging, including (18)F-FDG PET/CT. For 6 of the 8 patients, (64)Cu-DOTA-trastuzumab injection (364-512 MBq, 5 mg of trastuzumab) was preceded by trastuzumab infusion (45 mg). PET/CT (PET scan duration 1 h) was performed 21-25 (day 1) and 47-49 (day 2) h after (64)Cu-DOTA-trastuzumab injection. Scan fields of view were chosen on the basis of (18)F-FDG PET/CT. Tumor detection sensitivity and uptake analyses were limited to lesions identifiable on CT; lesions visualized relative to adjacent tissue on PET were considered PET-positive. Radiolabel uptake in prominent lesions was measured as maximum single-voxel standardized uptake value (SUVmax). Liver uptake of (64)Cu was reduced approximately 75% with the 45-mg trastuzumab predose, without significant effect on tumor uptake. The study included 89 CT-positive lesions. Detection sensitivity was 77%, 89%, and 93% for day 1, day 2, and (18)F-FDG, respectively. On average, tumor uptake was similar for (64)Cu-DOTA-trastuzumab and (18)F-FDG (SUVmax and range, 8.1 and 3.0-22.5 for day 1 [n = 48]; 8.9 and 0.9-28.9 for day 2 [n = 38]; 9.7 and 3.3-25.4 for (18)F-FDG [n = 56]), but same-lesion SUVmax was not correlated

    Improving caregivers' positive perception of their role may be important in reducing their subjective burden when caring for Alzheimer's disease (AD) patients with depression. The purpose of present study was to explore the moderating role of the positive aspects of caregiving (PAC) on the subjective burden on family caregivers when managing depressive behaviors. We conducted a cross-sectional study including 200 pairs of patients with mild AD and their caregivers from three communities and two hospitals in Taiyuan, China in October 2014. The latent variable interaction model based on a two stage least squares (2SLS) regression was fitted. A significant moderating effect of the PAC was found on the relationship between depression in patients with AD and the caregiver burden they cause. Caregivers dealing with patients with low levels of depression but with high levels of the PAC had significantly lower levels of caregiver burden compared to those caregivers with the low levels of PAC. Continuously detecting the patient's mental state combined with caregivers having an optimistic attitude towards life may improve the quality of life for both patients and caregivers.

    This study was carried out to investigate the growth of Gypsophila paniculata affected by pruning time (July 10, July 18, and July 25) and ridge position (middle or window side) under south-north oriented plastic house in sub-alpine area. The average night temperature was similar between the two ridges, but the average day temperature and soil temperature were higher at the middle ridge; particularly, there was distinct difference after late October. Also the accumulative solar radiation was higher at the middle ridge than the window side ridge owing to the shading by neighboring plastic house and the structure of plastic house. The root activity, photosynthetic rate and transpiration rate of plants surveyed in late October were inclined to be more increased at the middle than the window side ridge. The flowering traits at the pruning time of July 10 and July 18 were similar between the two ridges, but the flower malformation rate was higher at the middle ridge. On the other hand, in case of the pruning time of July 25, the blooming was advanced by 13 days, and the flowering traits such as flower stalk length and branch number were better; also, the flower malformation and rosette formation rate decreased at the middle ridge, because of its higher air and soil temperature and the accumulative solar radiation

    Human epidermal growth factor receptor 2-positive (HER2+) breast cancer comprises approximately 15%-20% of all breast cancers and is associated with a poor prognosis. The introduction of anti-HER2 therapy has significantly improved clinical outcomes for patients with HER2+ breast cancer, and multiple HER2-directed agents (ie, trastuzumab, pertuzumab, lapatinib, and ado-trastuzumab emtansine [T-DM1]) are approved for clinical use in various settings. The treatment landscape for patients with HER2+ breast cancer is continuing to evolve. While novel agents and therapeutic strategies are emerging, biologic therapies, particularly trastuzumab, are likely to remain a mainstay of treatment. However, access issues create barriers to the use of biologics, and there is evidence for underuse of trastuzumab worldwide. A biosimilar is a biologic product that is highly similar to a licensed biologic in terms of product safety and effectiveness. Biosimilars of trastuzumab are in development and may soon become available. The introduction of biosimilars may improve access to anti-HER2 therapies by providing additional treatment options and lower-cost alternatives. Because HER2-targeted drugs may be administered for extended periods of time and in combination with other systemic therapies, biosimilars have the potential to result in significant savings for healthcare systems. Herein we review current and emerging treatment options for, and discuss the possible role of biosimilars in, treating patients with HER2+ breast cancer. Copyright © 2017 Authors, Pfizer Inc.

    Full Text Available Tracey Hurrell, Kim OuthoffDepartment of Pharmacology, University of Pretoria, Pretoria, South AfricaIntroduction: Despite trastuzumab having enhanced selectivity for human epidermal growth factor receptor 2 (HER-2 overexpressing breast cancer cells, treatment is hampered by interindividual variation and tumors with high mitogenic potential. The lack of significant clinical benefit in certain patient cohorts suggests that HER-2 expression is ineffective as a sole prognostic indicator of response to therapy. Therefore, optimizing the clinical role of trastuzumab in drug combinations remains critical for clinical success.Aim: To investigate the effects of trastuzumab in combination with either doxorubicin or geldanamycin on in vitro cell viability, cell cycling, apoptosis and relative HER-2 expression in HER-2-positive (SK-BR-3 and estrogen receptor-positive (MCF-7 breast adenocarcinoma models.Results: HER-2-rich SK-BR-3 cells demonstrated a greater sensitivity to the effects of doxorubicin than MCF-7 cells. Concurrent trastuzumab exposure resulted in a further reduction in cell viability. This decreased cell viability induced by doxorubicin was associated with activation of executioner caspases as well as with alterations in cell-cycle kinetics, primarily promoting S-phase accumulation. Doxorubicin had no effect on surface HER-2 density expression. Geldanamycin reduced cell viability significantly greater in SK-BR-3 than MCF-7 cells, and was associated with G2 cell-cycle accumulation. The addition of trastuzumab did not augment these effects. Geldanamycin promoted substantial reductions in relative surface HER-2 density in SK-BR-3 cells.Conclusion: The in vitro data supported the rationale for using doxorubicin in trastuzumab-based therapies. Therefore, despite the incidence of cardiotoxicity, doxorubicin could retain a fundamental role in treating HER-2-positive breast cancer. While geldanamycin is a potent cytotoxic agent, its concurrent use

    Full Text Available Object: The aim of this study was to examine the effects of environmental, personal and event related factors on posttraumatic growth in breast cancer patients. Methods: The study was conducted with 134 women who are undergoing chemotherapy treatment or coming to the hospital for their routine controls. Revised Dyadic Adjustment Scale, The Impact of Event Scale, Posttraumatic Growth Inventory, Ways of Coping Inventory, Multidimensional Scale of Perceived Social Support, The General Self-Efficacy Scale-Turkish Form and Demographic Information Form was used. Results: Acoording to t-test analyses as the time passage from the diagnosis increases the perceived social support from the family members is increasing. Also while the group that had previous trauma experiences uses more helplessness coping styles, the group that had no previous trauma experience uses more problem focused coping style and showed greater posttraumatic growth. Results of the mediation analyses showed that problem focused coping has a mediator role in dyadic adjustment- posttraumatic growth; perceived social support from the family- posttraumatic growth; and self-efficacy- posttraumatic growth relationships. Discussion: The results of the current study are important in terms of developing new intervention programs that will help breast cancer patients to develop posttraumatic growth and also to better cope with cancer. This study is also important because the effect of marital adjustment and marital satisfaction on posttraumatic growth in breast cancer patients is an issue which is not well studied with Turkish sample.

    Information and Communication Technologies (ICTs) have become increasingly present in our lives, and their use has spread considerably. This paper presents a review of the way ICTs can help practitioners and researchers to study, promote, and train positive emotions. It is framed within the field of Positive Technologies: the applied scientific approach to the study of the use of technology to improve the quality of personal experience, with the goal of increasing wellbeing. First, the article presents an introduction to the topic of technologies and positive emotions. Then, it describes how ICTs can aid in monitoring, assessing, promoting, modifying, and training positive emotions. Finally, implications and future directions of the role of Positive Technologies in positive emotions are discussed. The authors conclude that, in the near future, Positive Technologies and the field of positive emotions will interact synergistically, producing an exponential growth in the understanding and promotion of positive emotions.

    Diagnostic criteria for borderline personality disorder (BPD) include interpersonal problems and high reactivity to negative social interactions. However, experimental studies on these symptoms are scarce, and it remains unclear whether reactivity is also altered in response to positive social interactions. To simulate such situations, the present study used videographic stimuli (E.Vids; Blechert, Schwitalla, & Wilhelm, 2013) in which actors express rejecting, neutral, or appreciating sentences. Twenty BPD patients and 20 healthy controls rated their emotional responses to these on pleasantness, arousal, and 11 specific emotions. In addition to elevated reactivity to negative E.Vids, patients with BPD showed marked reduction in pleasantness responses to positive E.Vids. Furthermore, they exhibited less pride, happiness, feelings of approval, and attraction/love in response to positive videos and more anger, anxiety, embarrassment, contempt, guilt, feelings of disapproval/rejection, and sadness to negative videos. Interestingly, BPD patients also reported negative emotions in response to positive videos. Implications for psychotherapy and research are discussed.

    Full Text Available Katalin Boér Department of Medical Oncology, Szent Margit Hospital, Budapest, Hungary Abstract: Breast cancer is a heterogeneous disease with multiple subgroups based on clinical and molecular characteristics. For the largest subgroup of breast cancers, hormone receptor-positive/human epidermal growth factor 2 (HER2-negative tumors, hormone treatment is the mainstay of therapy and is likely to result in significant improvement in disease outcomes. However, some of these cancers demonstrate de novo or acquired resistance to endocrine therapy. Despite intensive research to develop new strategies to enhance the efficacy of currently available treatment options for hormone receptor-positive breast cancer, progress has been slow, and there were few advances for a period of 10 years. In 2012, a new molecularly targeted therapeutic strategy, inhibition of mammalian target of rapamycin with everolimus, was introduced into clinical practice. Everolimus, in combination with a steroidal aromatase inhibitor, exemestane, resulted in an increase in progression-free survival, but not overall survival in patients with estrogen receptor (ER+ve advanced disease who had progressed on hormone therapy. In 2015, the first cyclin-dependent kinases 4/6 (CDK4/6 inhibitor, palbociclib, received accelerated US Food and Drug Administration approval for use in combination with letrozole for the treatment of postmenopausal ER+ve/HER2-ve advanced breast cancer as initial, endocrine-based therapy. The addition of palbociclib to endocrine therapy resulted in longer progression-free survival than letrozole alone. One year later, palbociclib received a new indication, use in combination with fulvestrant, in both premenopausal and postmenopausal females with advanced breast cancer of the same subtype with disease progression following endocrine therapy. Adding palbociclib to fulvestrant resulted in a significantly increased median progression-free survival compared to fulvestrant

    Low fertility limits crop production on acidic soils dominating much of the humid tropics. Biochar may be used as a soil enhancer, but little consensus exists on its effect on crop yield. Here we use a controlled, replicated and long-term field study in Sumatra, Indonesia, to investigate the longevity and mechanism of the effects of two contrasting biochars (produced from rice husk and cacao shell, and applied at dosages of 5 and 15tha -1 ) on maize production in a highly acidic Ultisol (pH KCl 3.6). Compared to rice husk biochar, cacao shell biochar exhibited a higher pH (9.8 vs. 8.4), CEC (197 vs. 20cmol c kg -1 ) and acid neutralizing capacity (217 vs. 45cmol c kg -1 ) and thus had a greater liming potential. Crop yield effects of cacao shell biochar (15tha -1 ) were also much stronger than those of rice husk biochar, and could be related to more favorable Ca/Al ratios in response to cacao shell biochar (1.0 to 1.5) compared to rice husk biochar (0.3 to 0.6) and nonamended plots (0.15 to 0.6). The maize yield obtained with the cacao shell biochar peaked in season 2, continued to have a good effect in seasons 3-4, and faded in season 5. The yield effect of the rice husk biochar was less pronounced and already faded from season 2 onwards. Crop yields were correlated with the pH-related parameters Ca/Al ratio, base saturation and exchangeable K. The positive effects of cocoa shell biochar on crop yield in this Ultisol were at least in part related to alleviation of soil acidity. The fading effectiveness after multiple growth seasons, possibly due to leaching of the biochar-associated alkalinity, indicates that 15tha -1 of cocoa shell biochar needs to be applied approximately every third season in order to maintain positive effects on yield.

    Literature, music, theater, and visual arts play an uncertain and limited role in medical education. One of the arguments often advanced in favor of teaching the humanities refers to their capacity to foster traits that not only improve practice, but might also reduce physician burnout-an increasing scourge in today's medicine. Yet, research remains limited. To test the hypothesis that medical students with higher exposure to the humanities would report higher levels of positive physician qualities (e.g., wisdom, empathy, self-efficacy, emotional appraisal, spatial skills), while reporting lower levels of negative qualities that are detrimental to physician well-being (e.g., intolerance of ambiguity, physical fatigue, emotional exhaustion, and cognitive weariness). An online survey. All students enrolled at five U.S. medical schools during the 2014-2015 academic year were invited by email to take part in our online survey. Students reported their exposure to the humanities (e.g., music, literature, theater, visual arts) and completed rating scales measuring selected personal qualities. In all, 739/3107 medical students completed the survey (23.8%). Regression analyses revealed that exposure to the humanities was significantly correlated with positive personal qualities, including empathy (p humanities and both a higher level of students' positive qualities and a lower level of adverse traits. These findings may carry implications for medical school recruitment and curriculum design.

    This study shows the accuracy of exclusive or earlier growth in anaerobic vials to predict Candida glabrata in a large series of candidemic patients from two European hospitals using the Bactec 9240 system. Alternatively, C. glabrata can be predicted by a time to positivity cutoff value, which should be determined for each setting. Copyright © 2014, American Society for Microbiology.

    Langer-Osuna, Jennifer

    2015-03-01

    This paper draws on the constructs of hybridity, figured worlds, and cultural capital to examine how a group of African-American students in a technology-driven, project-based algebra classroom utilized the computer as a resource to coordinate personal and mathematical positional identities during group work. Analyses of several vignettes of small group dynamics highlight how hybridity was established as the students engaged in multiple on-task and off-task computer-based activities, each of which drew on different lived experiences and forms of cultural capital. The paper ends with a discussion on how classrooms that make use of student-led collaborative work, and where students are afforded autonomy, have the potential to support the academic engagement of students from historically marginalized communities.

    Full Text Available Aim: The aim of this study was to identify the personality traits of alcohol and human immunodeficiency virus (HIV-positive patients and to compare them with normal controls. Materials and Methods: This cross-sectional study included 100 consecutive patients with alcohol dependence and HIV each and a control group of 100 normal cases without any physical or psychiatric illness. A score of 2 or less on the General Health Questionnaire was taken as cutoff, and the participants were included in the study with written informed consent. All participants were assessed with the NEO personality inventory revised and sensation-seeking scale (SSS. Results: There were significant differences among the study group on all the five factors, i.e., neuroticism (N, extraversion (E, conscientiousness (C, openness to experience (O, and agreeableness (A. On factor “N,” HIV and alcohol group scored significantly more as compared to normal group. Odds ratio revealed high neuroticism to be a risk factor in alcohol-dependent and HIV cases (P < 0.05. The normal group scored significantly higher on factor “E” as compared to HIV and alcohol cases. High scores on factor “E” and “C” have a protective. Odds ratio found low score of factor “C” as a risk factor; however, “O” did not emerge as a risk factor. The logistic regression revealed that high scores on “N” and “E” and low “A” score had a significant association with alcohol dependence (P < 0.05. Among HIV cases, high score on “N” and “E” and low “C” score emerged significant. Alcohol cases scored significantly more on boredom susceptibility (BS on SSS as compared to HIV and normal controls. On disinhibition (DIS, HIV cases and alcohol cases scored significantly higher as compared to normal group (P < 0.05. Conclusion: High “N” scores on NEO personality inventory are significantly associated with alcohol dependence and HIV while high scores on “E” and “C” have a

    Full Text Available Personality is the integration of characteristics acquired or brought by birth which separate the individual from others. Personality involves aspects of the individual's mental, emotional, social, and physical features in continuum. Several theories were suggested to explain developmental processes of personality. Each theory concentrates on one feature of human development as the focal point, then integrates with other areas of development in general. Most theories assume that childhood, especially up to 5-6 years, has essential influence on development of personality. The interaction between genetic and environmental factors reveals a unique personality along growth and developmental process. It could be said that individual who does not have any conflict between his/her basic needs and society's, has well-developed and psychologically healthy personality.

    Neoplastic cells proliferate rapidly and obtain requisite building blocks by reprogramming metabolic pathways that favor growth. Previously, we observed that prostate cancer cells uptake and store lipids in the form of lipid droplets, providing building blocks for membrane synthesis, to facilitate proliferation and growth. Mechanisms of lipid uptake, lipid droplet dynamics and their contribution to cancer growth have yet to be defined. This work is focused on elucidating the prostate cancer-specific modifications in lipid storage pathways so that these modified gene products can be identified and therapeutically targeted. To identify genes that promote lipid droplet formation and storage, the expression profiles of candidate genes were assessed and compared between peripheral blood mononuclear cells and prostate cancer cells. Subsequently, differentially expressed genes were inhibited and growth assays performed to elucidate their role in the growth of the cancer cells. Cell cycle, apoptosis and autophagy assays were performed to ascertain the mechanism of growth inhibition. Our results indicate that DGAT1, ABHD5, ACAT1 and ATGL are overexpressed in prostate cancer cells compared to PBMCs and of these overexpressed genes, DGAT1 and ABHD5 aid in the growth of the prostate cancer cells. Blocking the expression of both DGAT1 and ABHD5 results in inhibition of growth, cell cycle block and cell death. DGAT1 siRNA treatment inhibits lipid droplet formation and leads to autophagy where as ABHD5 siRNA treatment promotes accumulation of lipid droplets and leads to apoptosis. Both the siRNA treatments reduce AMPK phosphorylation, a key regulator of lipid metabolism. While DGAT1 siRNA reduces phosphorylation of ACC, the rate limiting enzyme in de novo fat synthesis and triggers phosphorylation of raptor and ULK-1 inducing autophagy and cell death, ABHD5 siRNA decreases P70S6 phosphorylation, leading to PARP cleavage, apoptosis and cell death. Interestingly, DGAT-1 is involved

    The aim of this research was to evaluate the physiological activity and growth of willow (Salix viminalis L.) plants cultivated under the conditions of adverse temperature and soil moisture content, and to assess the effect of the foliar application of Biojodis (1.0%) and Asahi SL (0.03%) bio-stimulators, or a mixture of Microcistis aeruginosa MKR 0105 and Anabaena PCC 7120 cyanobacteria under such changing growth conditions. The obtained results showed different reactions to the applied constant or periodically changed temperature and soil moisture content. The plants which grew at periodically changed adverse temperature (from -5 to 40oC) or in scantily (20% m.c.) or excessively (60% m.c.) watered soils, grew slowly, in comparison with those growing at 20oC and in optimally moistened soil (30% m.c.). Foliar application of Biojodis and Asahi SL cyanobacteria increased the growth of willow at optimal and adverse temperature or in scantily and excessively moistened soil. The changes in plant growth were associated with the changes in electrolyte leakage, activity of acid or alkaline phosphatases, RNase, index of chlorophyll content in leaves and gas exchange. The above indicates that the foliar application of the studied cyanobacteria and bio-stimulators partly alleviates the harmful impact of adverse temperature and water stress on growth and physiological activity of willow plants

    Background: We have previously shown that fat-free mass (FFM) at birth is associated with height at 2 y of age in Ethiopian children. However, to our knowledge, the relation between changes in body composition during early infancy and later linear growth has not been studied. Objective: This study...... examined the associations of early infancy fat mass (FM) and FFM accretion with linear growth from 1 to 5 y of age in Ethiopian children. Methods: In the infant Anthropometry and Body Composition (iABC) study, a prospective cohort study was carried out in children in Jimma, Ethiopia, followed from birth...... to 5 y of age. FM and FFM were measured ≤6 times from birth to 6 mo by using air-displacement plethysmography. Linear mixed-effects models were used to identify associations between standardized FM and FFM accretion rates during early infancy and linear growth from 1 to 5 y of age. Standardized...

  13. Acetate supplementation induces growth arrest of NG2/PDGFRα-positive oligodendroglioma-derived tumor-initiating cells.

    Directory of Open Access Journals (Sweden)

    Patrick M Long

    Full Text Available Cancer is associated with globally hypoacetylated chromatin and considerable attention has recently been focused on epigenetic therapies. N-acetyl-L-aspartate (NAA, the primary storage form of acetate in the brain, and aspartoacylase (ASPA, the enzyme responsible for NAA catalysis to generate acetate and ultimately acetyl-Coenzyme A for histone acetylation, are reduced in oligodendroglioma. The short chain triglyceride glyceryl triacetate (GTA, which increases histone acetylation and inhibits histone deacetylase expression, has been safely used for acetate supplementation in Canavan disease, a leukodystrophy due to ASPA mutation. We demonstrate that GTA induces cytostatic G0 growth arrest of oligodendroglioma-derived cells in vitro, without affecting normal cells. Sodium acetate, at doses comparable to that generated by complete GTA catalysis, but not glycerol also promoted growth arrest, whereas long chain triglycerides promoted cell growth. To begin to elucidate its mechanism of action, the effects of GTA on ASPA and acetyl-CoA synthetase protein levels and differentiation of established human oligodendroglioma cells (HOG and Hs683 and primary tumor-derived oligodendroglioma cells that exhibit some features of cancer stem cells (grade II OG33 and grade III OG35 relative to an oligodendrocyte progenitor line (Oli-Neu were examined. The nuclear localization of ASPA and acetyl-CoA synthetase-1 in untreated cells was regulated during the cell cycle. GTA-mediated growth arrest was not associated with apoptosis or differentiation, but increased expression of acetylated proteins. Thus, GTA-mediated acetate supplementation may provide a safe, novel epigenetic therapy to reduce the growth of oligodendroglioma cells without affecting normal neural stem or oligodendrocyte progenitor cell proliferation or differentiation.

    Few studies have monitored late presentation (LP) of HIV infection over the European continent, including Eastern Europe. Study objectives were to explore the impact of LP on AIDS and mortality. LP was defined in Collaboration of Observational HIV Epidemiological Research Europe (COHERE) as HIV diagnosis with a CD4 count HIV diagnosis among persons presenting for care between 1 January 2000 and 30 June 2011. Logistic regression was used to identify factors associated with LP and Poisson regression to explore the impact on AIDS/death. 84,524 individuals from 23 cohorts in 35 countries contributed data; 45,488 were LP (53.8%). LP was highest in heterosexual males (66.1%), Southern European countries (57.0%), and persons originating from Africa (65.1%). LP decreased from 57.3% in 2000 to 51.7% in 2010/2011 (adjusted odds ratio [aOR] 0.96; 95% CI 0.95-0.97). LP decreased over time in both Central and Northern Europe among homosexual men, and male and female heterosexuals, but increased over time for female heterosexuals and male intravenous drug users (IDUs) from Southern Europe and in male and female IDUs from Eastern Europe. 8,187 AIDS/deaths occurred during 327,003 person-years of follow-up. In the first year after HIV diagnosis, LP was associated with over a 13-fold increased incidence of AIDS/death in Southern Europe (adjusted incidence rate ratio [aIRR] 13.02; 95% CI 8.19-20.70) and over a 6-fold increased rate in Eastern Europe (aIRR 6.64; 95% CI 3.55-12.43). LP has decreased over time across Europe, but remains a significant issue in the region in all HIV exposure groups. LP increased in male IDUs and female heterosexuals from Southern Europe and IDUs in Eastern Europe. LP was associated with an increased rate of AIDS/deaths, particularly in the first year after HIV diagnosis, with significant variation across Europe. Earlier and more widespread testing, timely referrals after testing positive, and improved retention in care strategies are required to further

    The present study examined the patterns and sources of 10-year stability and change of adult personality assessed by the 5 domains and 30 facets of the Revised NEO Personality Inventory. Phenotypic and biometric analyses were performed on data from 126 identical and 61 fraternal twins from the Bielefeld Longitudinal Study of Adult Twins (BiLSAT). Consistent with previous research, LGM analyses revealed significant mean-level changes in domains and facets suggesting maturation of personality. There were also substantial individual differences in the change trajectories of both domain and facet scales. Correlations between age and trait changes were modest and there were no significant associations between change and gender. Biometric extensions of growth curve models showed that 10-year stability and change of personality were influenced by both genetic as well as environmental factors. Regarding the etiology of change, the analyses uncovered a more complex picture than originally stated, as findings suggest noticeable differences between traits with respect to the magnitude of genetic and environmental effects.

    2002-01-01

    The "trickle-down" theory argues that wider income differences are good for economic growth, that growth is good for the poor, and therefore that widening income disparities benefit the poor. The theory thus fulfills Rawlsian principles of justice. The purpose of this article is to present a preliminary evaluation of the correctness of this theory. Income data for 21 countries were obtained from the Luxembourg Income Study, for the period 1985-95. The results of the analysis show no clear connections between inequality and economic prosperity. The wider the inequality, the worse is the absolute income of the poor. In this respect the theory is falsified. However, the trickle-down theory is partly correct in arguing for the beneficial effects of economic growth for the poor: the absolute income level of the poor is dependent on what is happening in the national economy, while the incidence and depth of poverty in advanced countries are not so much associated with economic factors as a result of national social policy programs.

    Full Text Available Pilot studies using technology-aided programs to promote verbal reminiscence and mild physical activity (i.e., positive forms of engagement in persons with moderate or severe Alzheimer’s disease have provided promising results (Lancioni et al., 2015a, b. The present two studies were aimed at upgrading and/or extending the assessment of those programs. Specifically, Study 1 upgraded the program for verbal reminiscence and assessed it with eight new participants. The upgraded version automatically monitored the participants’ verbal behavior during the sessions, in which photos and brief videos were used to foster verbal reminiscence. Monitoring allowed computer approval and reminders to be consistent with the participants’ behavior. Study 2 extended the assessment of the program for promoting mild physical activity with 10 new participants for whom arm-raising responses were targeted. The results of Study 1 showed that the participants’ mean percentages of intervals with verbal engagement/reminiscence were below 10 during baseline and control sessions and between above 50 and nearly 80 during the intervention. The results of Study 2 showed that the mean frequencies of arm-raising responses were about or below four and between about 10 and 19 per session during the baseline and the intervention, respectively. The general implications of the aforementioned results and the need for new research in the area were discussed.

    EVC is a novel protein mutated in the human chondroectodermal dysplasia Ellis-van Creveld syndrome (EvC; OMIM: 225500). We have inactivated Evc in the mouse and show that Evc(-/-) mice develop an EvC-like syndrome, including short ribs, short limbs and dental abnormalities. lacZ driven by the Evc promoter revealed that Evc is expressed in the developing bones and the orofacial region. Antibodies developed against Evc locate the protein at the base of the primary cilium. The growth plate of Evc(-/-) mice shows delayed bone collar formation and advanced maturation of chondrocytes. Indian hedgehog (Ihh) is expressed normally in the growth plates of Evc(-/-) mice, but expression of the Ihh downstream genes Ptch1 and Gli1 was markedly decreased. Recent studies have shown that Smo localises to primary cilia and that Gli3 processing is defective in intraflagellar transport mutants. In vitro studies using Evc(-/-) cells demonstrate that the defect lies downstream of Smo. Chondrocyte cilia are present in Evc(-/-) mice and Gli3 processing appears normal by western blot analysis. We conclude that Evc is an intracellular component of the hedgehog signal transduction pathway that is required for normal transcriptional activation of Ihh target genes.

    Core-shell group III-nitride nano- and microrods (NAMs) enable a significant increase of the active layer area by exploiting the non-polar side facets (m-planes) and thus can potentially contribute to mitigating the so-called efficiency droop in LEDs. GaN NAMs exhibiting high aspect ratios were grown in a production-type MOVPE system. Low V/III ratio, hydrogen-rich carrier gas mixture and surfactants supported the 3D growth of the pencil-shape n-type GaN core. Desired narrow distributions of shape, diameter and height were achieved. The arrangement of the NAMs was controlled by patterns etched into SiO{sub 2} masks deposited on GaN templates. The active layer (InGaN/GaN SQW and MQWs) and the layer for the p-side were deposited with 2D-like conditions wrapped around the core. The crystalline quality of the NAMs, shell growth rates and the Indium distribution were investigated by high resolution transmission electron microscopy. Furthermore, optical emission was studied using density-dependent photoluminescence spectroscopy.

    For the first time, the (003) cracking is observed and determined to be the major cracking mechanism for the primary particles of Ni-rich layered dioxides as the positive electrode for Li-ion batteries. Using transmission electron microscopy techniques, here we show that the propagation and fracturing of platelet-like rock-salt phase along the (003) plane of the layered oxide are the leading cause for the cracking of primary particles. The fracturing of the rock-salt platelet is induced by the stress discontinuity between the parent layered oxide and the rock-salt phase. The high nickel content is considered to be the key factor for the formation of the rock-salt platelet and thus the (003) cracking. The (003)-type cracking can be a major factor for the structural degradation and associated capacity fade of the layered positive electrode.

    2013-07-01

    Sulfated glycosaminoglycans (GAGs) are known to interact electrostatically with positively charged growth factors to modulate signaling. Therefore, regulating the degree of sulfation of GAGs may be a promising approach to tailor biomaterial carriers for controlled growth factor delivery and release. For this study, chondroitin sulfate (CS) was first desulfated to form chondroitin, and resulting crosslinked CS and chondroitin hydrogels were examined in vitro for release of positively charged model protein (histone) and for their effect on cartilaginous differentiation of encapsulated human mesenchymal stem cells (MSCs). Desulfation significantly increased the release of histone from chondroitin hydrogels (30.6 ± 2.3 μg released over 8 days, compared to natively sulfated CS with 20.2 ± 0.8 μg), suggesting that sulfation alone plays a significant role in modulating protein interactions with GAG hydrogels. MSCs in chondroitin hydrogels significantly upregulated gene expression of collagen II and aggrecan by day 21 in chondrogenic medium (115 ± 100 and 23.1 ± 7.9 fold upregulation of collagen II and aggrecan, respectively), compared to CS hydrogels and PEG-based swelling controls, indicating that desulfation may actually enhance the response of MSCs to soluble chondrogenic cues, such as TGF-β1. Thus, desulfated chondroitin materials present a promising biomaterial tool to further investigate electrostatic GAG/growth factor interactions, especially for repair of cartilaginous tissues.

    Physical and psychomotor development of children whose grandparents were occupationally exposed to chronic external gamma-radiation at doses 0.1 to over 400 Gy was studied. Mean values of the major anthropometric parameters at first and over the first year of life, growth and mass increment rates were assessed, as well as body length growth per quarter, age of the doubling and tripling the body mass at birth, and age of the cross-over of the head and chest circumference values. Share of infants with the harmonic and dysharmonic development, of those small-for-date and large-for-date were estimated, and the psychomotor development and the rate of biologic maturation were assessed. No significant differences between studied parameters of the test group and the reference group were detected

    Talented individuals are seen as drivers of long-term growth, but how do they realize their full potential? In this paper, I show that lifetime earnings of high-IQ men and women are substantially influenced by their personality traits, in addition to intelligence and education. Personality traits......, as identified in a factor model, significantly affect earnings, but not for young workers. The effects are furthermore heterogeneous by educational attainment. For women, personality traits do not affect family earnings in the same way as own earnings. Personality and IQ also influence earnings indirectly...... through education, which has sizeable positive rates of return for men in this sample. Women’s returns to education past a bachelor’s degree are lowered through worse marriage prospects, which offset gains to education in terms of own earnings. The causal effect of education is identified through matching...

    Background Persons infected with human immunodeficiency virus (HIV) have increased rates of coronary artery disease (CAD). The relative contribution of genetic background, HIV-related factors, antiretroviral medications, and traditional risk factors to CAD has not been fully evaluated in the setting of HIV infection. Methods In the general population, 23 common single-nucleotide polymorphisms (SNPs) were shown to be associated with CAD through genome-wide association analysis. Using the Metabochip, we genotyped 1875 HIV-positive, white individuals enrolled in 24 HIV observational studies, including 571 participants with a first CAD event during the 9-year study period and 1304 controls matched on sex and cohort. Results A genetic risk score built from 23 CAD-associated SNPs contributed significantly to CAD (P = 2.9×10−4). In the final multivariable model, participants with an unfavorable genetic background (top genetic score quartile) had a CAD odds ratio (OR) of 1.47 (95% confidence interval [CI], 1.05–2.04). This effect was similar to hypertension (OR = 1.36; 95% CI, 1.06–1.73), hypercholesterolemia (OR = 1.51; 95% CI, 1.16–1.96), diabetes (OR = 1.66; 95% CI, 1.10–2.49), ≥1 year lopinavir exposure (OR = 1.36; 95% CI, 1.06–1.73), and current abacavir treatment (OR = 1.56; 95% CI, 1.17–2.07). The effect of the genetic risk score was additive to the effect of nongenetic CAD risk factors, and did not change after adjustment for family history of CAD. Conclusions In the setting of HIV infection, the effect of an unfavorable genetic background was similar to traditional CAD risk factors and certain adverse antiretroviral exposures. Genetic testing may provide prognostic information complementary to family history of CAD. PMID:23532479

    Background Few studies have monitored late presentation (LP) of HIV infection over the European continent, including Eastern Europe. Study objectives were to explore the impact of LP on AIDS and mortality. Methods and Findings LP was defined in Collaboration of Observational HIV Epidemiological Research Europe (COHERE) as HIV diagnosis with a CD4 count Europe among homosexual men, and male and female heterosexuals, but increased over time for female heterosexuals and male intravenous drug users (IDUs) from Southern Europe and in male and female IDUs from Eastern Europe. 8,187 AIDS/deaths occurred during 327,003 person-years of follow-up. In the first year after HIV diagnosis, LP was associated with over a 13-fold increased incidence of AIDS/death in Southern Europe (adjusted incidence rate ratio [aIRR] 13.02; 95% CI 8.19–20.70) and over a 6-fold increased rate in Eastern Europe (aIRR 6.64; 95% CI 3.55–12.43). Conclusions LP has decreased over time across Europe, but remains a significant issue in the region in all HIV exposure groups. LP increased in male IDUs and female heterosexuals from Southern Europe and IDUs in Eastern Europe. LP was associated with an increased rate of AIDS/deaths, particularly in the first year after HIV diagnosis, with significant variation across Europe. Earlier and more widespread testing, timely referrals after testing positive, and improved retention in care strategies are required to further reduce the incidence of LP.

    Although identification of human epidermal growth factor receptor 2 (Her2) positive breast cancer represents one of the greatest advances over the past 3 decades, it has not been studied extensively on a national level. The National Cancer Database is a joint project of the American Cancer Society and the American College of Surgeons and contains data on about 70% of the cancer cases in the United States. Data on Her2 have been collected since 2010 and was used for this study. Of 298,937 cases of invasive breast cancer with known Her2 status diagnosed in 2010 and 2011, 43,485 (14.5%) were Her2 positive. Her2 positivity was greatest in Asian/Pacific Islanders and least in non-Hispanic Whites and was markedly more common in younger women. The incidence of Her2 positive tumors ranged from a low of 13.9% in the Mountain West region to a high of 16.0% in the West South Central region (P breast preservation (odds ratio = .78, confidence interval = .76 to .80). Her2 positive tumors have distinct epidemiologic, clinical, and treatment characteristics. Copyright © 2016 Elsevier Inc. All rights reserved.

    Highlights: • Notch signaling pathway members are expressed lower levels in CD133+ cells. • CD133+ cells are not as sensitive as CD133− cells to chemotherapy. • GSI could inhibit the growth of both CD133+ and CD133− cells. • Blockade of Notch signaling pathway enhanced the effect of chemotherapy with CDDP. • DAPT/CDDP co-therapy caused G2/M arrest and elimination in CD133+ cells. - Abstract: Cancer stem cells (CSCs) are believed to play an important role in tumor growth and recurrence. These cells exhibit self-renewal and proliferation properties. CSCs also exhibit significant drug resistance compared with normal tumor cells. Finding new treatments that target CSCs could significantly enhance the effect of chemotherapy and improve patient survival. Notch signaling is known to regulate the development of the lungs by controlling the cell-fate determination of normal stem cells. In this study, we isolated CSCs from the human lung adenocarcinoma cell line A549. CD133 was used as a stem cell marker for fluorescence-activated cell sorting (FACS). We compared the expression of Notch signaling in both CD133+ and CD133− cells and blocked Notch signaling using the γ-secretase inhibitor DAPT (GSI-IX). The effect of combining GSI and cisplatin (CDDP) was also examined in these two types of cells. We observed that both CD133+ and CD133− cells proliferated at similar rates, but the cells exhibited distinctive differences in cell cycle progression. Few CD133+ cells were observed in the G{sub 2}/M phase, and there were half as many cells in S phase compared with the CD133− cells. Furthermore, CD133+ cells exhibited significant resistance to chemotherapy when treated with CDDP. The expression of Notch signaling pathway members, such as Notch1, Notch2 and Hes1, was lower in CD133+ cells. GSI slightly inhibited the proliferation of both cell types and exhibited little effect on the cell cycle. The inhibitory effects of DPP on these two types of cells were

    There is growing evidence for the efficacy and effectiveness of psychotherapy in patients with personality disorder (PD), but very little is known about the factors underlying these effects. Two-polarities models of personality development provide an empirically supported approach to studying therapeutic change. Briefly, these models argue that personality pathology is characterized by an imbalance between development of the capacity for self-definition and for relatedness, with an exaggerated emphasis on issues regarding self-definition and relatedness being expressed in high levels of self-critical perfectionism (SCP) and dependency, respectively. This study used data from a study of 111 patients with PD who received long-term hospitalization-based psychodynamic treatment to investigate whether (a) treatment was related to changes in SCP, dependency, and symptomatic distress; (b) these changes could be explained by pretreatment levels of SCP, dependency, and/or symptomatic distress; and (c) changes in these personality dimensions over time were associated with symptomatic improvement. SCP, dependency, and symptomatic distress were assessed at admission (baseline), at 12 and 24 weeks into treatment, and at discharge. Parallel process multilevel growth modeling showed that (a) treatment was associated with a significant decrease in levels of SCP, dependency, and symptomatic distress, whereas (b) pretreatment levels of each of these three factors did not predict the decreases observed, and (c) changes in SCP, but not dependency, were associated with the rate of decrease in symptomatic distress over time. Implications of these findings for our understanding of therapeutic change in the treatment of PD are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Nationwide epidemiological cohort study. To characterize the incidence of second cervical vertebral (C2) fractures by age and geographical region among the elderly Medicare population and to elucidate if the rate changed in the years 2005 to 2008. Recent publications hypothesized that the rate of cervical vertebral fractures may be increasing. To date, there are no published nationwide reports describing the incidence and demographics of these injuries in the elderly US population. Incidence of C2 fracture in the years 2005 to 2008 was determined by querying PearlDiver Technologies, Inc. (Warsaw, IN), a commercially available database, using International Classification of Diseases code 805.02. Rates were calculated using the PearlDiver reported person-counts as the numerator and the Center for Medicare and Medicare Services midyear population file as the denominator, and reported per 10,000 person-years (10,000 p-y). The age and geographical distributions of fractures were examined. Variability in rates was analyzed using the mean, standard deviation, 95% confidence intervals, χ tests, and Pearson correlation coefficients. Although the elderly population increased by 6% between 2005 and 2008, the annual incidence of C2 fracture rose by 21%, from 1.58 to 1.91 per 10,000 p-y, trending upward in a straight-line function (r = 0.999, P = 0.0006). The incidence of fracture varied between age groups; however, an increase was observed in all age groups. Persons aged 65 to 74 years (the youngest age group) experienced the lowest incidence (0.63 in 2005 to 0.71 in 2008), and the rate of increase was the smallest among the age groups examined (13%). Persons aged 85 and older demonstrated the highest incidence (4.36-5.67) and the greatest increase (30%). From 2005 to 2008, the overall incidence of C2 fracture rose at a rate that was 3.5 times faster than the elderly population growth.

  15. Positive and negative effects of habitat-forming algae on survival, growth and intra-specific competition of limpets.

    Full Text Available Understanding the effects of environmental change on the distribution and abundance of strongly interacting organisms, such as intertidal macroalgae and their grazers, needs a thorough knowledge of their underpinning ecological relationships. Control of grazer-plant interactions is bi-directional on northwestern European coasts: grazing by limpets structures populations of macroalgae, while macroalgae provide habitat and food for limpets. Scottish shores dominated by the macroalga Fucus vesiculosus support lower densities and larger sizes of limpets Patella vulgata than shores with less Fucus. These patterns may be due to differences in inter-size-class competitive interactions of limpets among shores with different covers of Fucus. To examine this model, densities of small and large limpets were manipulated in plots with and without Fucus. Amounts of biofilm were measured in each plot. The presence of Fucus increased survival but hindered growth of small (15 mm TL limpets, which were negatively affected by the presence of large limpets (31 mm TL. In contrast, large limpets were not affected by the presence of Fucus or of small limpets. This suggests the occurrence of asymmetric inter-size-class competition, which was influenced by the presence of macroalgae. Macroalgae and increased densities of limpets did not influence amounts of biofilm. Our findings highlight the role of interactions among organisms in generating ecological responses to environmental change.

    Some herbivore-induced-plant volatiles (HIPVs) compounds are vital for the functioning of an ecosystem, by triggering multi-trophic interactions for natural enemies, plants and herbivores. However, the effect of these chemicals, which play a crucial role in regulating the multi-trophic interactions between plant-herbivore-entomopathogenic fungi, is still unknown. To fill this scientific gap, we therefore investigated how these chemicals influence the entomopathogenic fungi growth and efficacy. In this study, Lipaphis erysimi induced Arabidopsis thaliana HIPVs were collected using headspace system and detected with GC-MS, and then analyzed the effects of these HIPVs chemicals on Lecanicillium lecanii strain V3450. We found that the HIPVs menthol and methyl salicylate at 1 and 10 nmol·ml-1 improved many performance aspects of the fungus, such as germination, sporulation, appressorial formation as well as its pathogenicity and virulence. These findings are not only important for understanding the multi-trophic interactions in an ecosystem, but also would contribute for developing new and easier procedures for conidial mass production as well as improve the pathogenicity and virulence of entomopathogenic fungi in biological pest management strategies.

    Laboratory monitoring of HIV-infected children is the current standard of care in the United States to guide the appropriate use of antiretroviral therapy (ART). Although ART is becoming a reality in some developing countries, laboratory monitoring of ART is costly, necessitating creative approaches to monitoring. As an initial step to guide monitoring of HIV progression in low resource settings, we assessed the utility of the physical examination to predict clinical progression of HIV. We conducted a retrospective cohort study of HIV-infected children using data from Pediatric AIDS Clinical Trials Group Protocol 300. We developed a clinical predictive model, and compared the utility of the clinical model to the change in HIV RNA viral load as diagnostic tests of ART failure. The clinical model incorporated treatment regimen, age, and height velocity: a three-level clinical predictive model provided likelihood ratios of 0.3, 3.9, and 14. For decline in RNA the likelihood ratios were 0.2 (> 1 log decline), 1.4, and 3.5 (> log increase). We developed a simple clinical predictive model that was able to predict clinical progression of HIV after initiation of new ART. The clinical model performed similarly to using changes in HIV RNA viral load. These data should be validated internationally and prospectively, because the test subjects were from a resource rich environment and growth patterns in undernourished children may be impacted differently by HIV and its treatment. The model was most pertinent to children 36 months of age or younger, and was conducted in children receiving monotherapy and dual therapy.

    Thyrotropin (thyroid stimulating hormone [TSH]) secreting pituitary adenomas (TSHoma) are rare adenomas presenting with hyperthyroidism due to impaired negative feedback of thyroid hormone on the pituitary and inappropriate TSH secretion. This article presents a case of TSH-secreting macroadenoma without any clinical hyperthyroidism symptoms accompanying immunoreaction with growth hormone (GH) and prolactin. A 36-year-old female patient was admitted with complaints of irregular menses and blurred vision. On physical exam, she had bitemporal hemianopsia defect. Magnetic resonance imaging (MRI) evaluation showed suprasellar macroadenoma measuring 33 mm × 26 mm × 28 mm was detected on pituitary MRI. She had no hyperthyroidism symptoms clinically. Although free T4 and free T3 levels were elevated, TSH level was inappropriately within the upper limit of normal. Response to T3 suppression and thyrotropin releasing hormone-stimulation test was inadequate. Other pituitary hormones were normal. Transsphenoidal adenomectomy was performed due to parasellar compression findings. Immunohistochemically widespread reaction was observed with TSH, GH and prolactin in the adenoma. The patient underwent a second surgical procedure 2 months later due to macroscopic residual tumor, bitemporal hemianopsia and a suprasellar homogenous uptake with regular borders on indium-111 octreotide scintigraphy. After second surgery; due to ongoing symptoms and residual tumor, she was managed with octreotide and cabergoline treatment. On her follow-up with medical treatment, TSH and free T4 values were within normal limits. Although silent TSHomas are rare, they may arise with compression symptoms as in our case. The differential diagnosis of secondary hyperthyroidism should include TSHomas and thyroid hormone receptor resistance syndrome.

    PURPOSE: Trastuzumab shows clinical activity in human epidermal growth factor receptor 2 (HER-2)-positive early and advanced breast cancer. In the German Breast Group 26/Breast International Group 03-05 trial, we investigated if trastuzumab treatment should be continued beyond progression. METHODS......: Patients with HER-2-positive breast cancer that progresses during treatment with trastuzumab were randomly assigned to receive capecitabine (2,500 mg/m(2) body-surface area on days 1 through 14 [1,250 mg/m(2) semi-daily]) alone or with continuation of trastuzumab (6 mg/kg body weight) in 3-week cycles....... The primary end point was time to progression. RESULTS: We randomly assigned 78 patients to capecitabine and 78 patients to capecitabine plus trastuzumab. Sixty-five events and 38 deaths in the capecitabine group and 62 events and 33 deaths in the capecitabine-plus-trastuzumab group occurred during 15...

    Full Text Available This paper presents a biopsychosocial model of self-regulation, executive functions, and personal growth that we have applied to Goal-Directed Resilience in Training (GRIT interventions for posttraumatic stress disorder (PTSD, obesity, and chronic pain. Implications of the training for the prevention of maladaptation, including psychological distress and health declines, and for promoting healthy development are addressed. Existing models of attention, cognition, and physiology were sourced in combination with qualitative study findings in developing this resilience skills intervention. We used qualitative methods to uncover life skills that are most salient in cases of extreme adversity, finding that goal-directed actions that reflected an individual’s values and common humanity with others created a context-independent domain that could compensate for the effects of adversity. The efficacy of the resilience skills intervention for promoting positive emotion, enhancing neurocognitive capacities, and reducing symptoms was investigated in a randomized controlled trial with a veteran population diagnosed with PTSD. The intervention had low attrition (8% and demonstrated improvement on symptom and wellbeing outcomes, indicating that the intervention may be efficacious for PTSD and that it taps into those mechanisms which the intervention was designed to address. Feasibility studies for groups with comorbid diagnoses, such as chronic pain and PTSD, also showed positive results, leading to the application of the GRIT intervention to other evocative contexts such as obesity and chronic pain.

  2. Ocean acidification reverses the positive effects of seawater pH fluctuations on growth and photosynthesis of the habitat-forming kelp, Ecklonia radiata.

    Ocean acidification (OA) is the reduction in seawater pH due to the absorption of human-released CO2 by the world's oceans. The average surface oceanic pH is predicted to decline by 0.4 units by 2100. However, kelp metabolically modifies seawater pH via photosynthesis and respiration in some temperate coastal systems, resulting in daily pH fluctuations of up to ±0.45 units. It is unknown how these fluctuations in pH influence the growth and physiology of the kelp, or how this might change with OA. In laboratory experiments that mimicked the most extreme pH fluctuations measured within beds of the canopy-forming kelp Ecklonia radiata in Tasmania, the growth and photosynthetic rates of juvenile E. radiata were greater under fluctuating pH (8.4 in the day, 7.8 at night) than in static pH treatments (8.4, 8.1, 7.8). However, pH fluctuations had no effect on growth rates and a negative effect on photosynthesis when the mean pH of each treatment was reduced by 0.3 units. Currently, pH fluctuations have a positive effect on E. radiata but this effect could be reversed in the future under OA, which is likely to impact the future ecological dynamics and productivity of habitats dominated by E. radiata.

    We demonstrate the fabrication of N-face GaN nanorods by metal organic vapour phase epitaxy (MOVPE), using continuous-flux conditions. This is in contrast to other approaches reported so far, which have been based on growth modes far off the conventional growth regimes. For position control of nanorods an SiO{sub 2} masking layer with a dense hole pattern on a c-plane sapphire substrate was used. Nanorods with InGaN/GaN heterostructures have been grown catalyst-free. High growth rates up to 25 {mu}m h{sup -1} were observed and a well-adjusted carrier gas mixture between hydrogen and nitrogen enabled homogeneous nanorod diameters down to 220 nm with aspect ratios of approximately 8:1. The structural quality and defect progression within nanorods were determined by transmission electron microscopy (TEM). Different emission energies for InGaN quantum wells (QWs) could be assigned to different side facets by room temperature cathodoluminescence (CL) measurements.

    We demonstrate the fabrication of N-face GaN nanorods by metal organic vapour phase epitaxy (MOVPE), using continuous-flux conditions. This is in contrast to other approaches reported so far, which have been based on growth modes far off the conventional growth regimes. For position control of nanorods an SiO 2 masking layer with a dense hole pattern on a c-plane sapphire substrate was used. Nanorods with InGaN/GaN heterostructures have been grown catalyst-free. High growth rates up to 25 μm h -1 were observed and a well-adjusted carrier gas mixture between hydrogen and nitrogen enabled homogeneous nanorod diameters down to 220 nm with aspect ratios of approximately 8:1. The structural quality and defect progression within nanorods were determined by transmission electron microscopy (TEM). Different emission energies for InGaN quantum wells (QWs) could be assigned to different side facets by room temperature cathodoluminescence (CL) measurements.

    The effects of solar UV radiation (280-400 nm) on growth, quantum yield and pigmentation in Gracilaria lemaneiformis were investigated when the thalli were cultured under solar radiation with or without UV for a period of 15 days. Presence of UV-A (315-400 nm) enhanced the relative growth rate, while UV-B (218-315 nm) inhibited it. The positive effect of UV-A and negative effect of UV-B counteracted to result in an insignificant impact of UVR on growth. During the noon period, both UV-A and UV-B resulted in the decrease of maximum quantum yield (Fv/Fm), but UV-B aided in the recovery of the yield in the late afternoon, reflecting that UV-B might be used as a signal in photorepair processes. UV induced the accumulation of UV-absorbing compounds (UVAC) to defend against the harmful UVR. However, the accumulation of UVAC took a much longer time compared to that previously reported, which was probably due to the lower levels of solar radiation and water temperature in the early spring period. Unknown UV-absorbing compounds (UVAC), which peaked at 265 nm, probably the precursor of MAAs (UVAC(325)), accumulated under moderate levels of solar radiation and were transformed to MAAs under higher solar radiation.

    Glycoprotein A repetitions predominant (GARP) (encoded by the Lrrc32 gene) plays important roles in cell-surface docking and activation of TGFβ. However, GARP's role in organ development in mammalian systems is unclear. To determine the function of GARP in vivo , we generated a GARP KO mouse model. Unexpectedly, the GARP KO mice died within 24 h after birth and exhibited defective palatogenesis without apparent abnormalities in other major organs. Furthermore, we observed decreased apoptosis and SMAD2 phosphorylation in the medial edge epithelial cells of the palatal shelf of GARP KO embryos at embryonic day 14.5 (E14.5), indicating a defect in the TGFβ signaling pathway in the GARP-null developing palates. Of note, the failure to develop the secondary palate and concurrent reduction of SMAD phosphorylation without other defects in GARP KO mice phenocopied TGFβ3 KO mice, although GARP has not been suggested previously to interact with TGFβ3. We found that GARP and TGFβ3 co-localize in medial edge epithelial cells at E14.5. In vitro studies confirmed that GARP and TGFβ3 directly interact and that GARP is indispensable for the surface expression of membrane-associated latent TGFβ3. Our findings indicate that GARP is essential for normal morphogenesis of the palate and demonstrate that GARP plays a crucial role in regulating TGFβ3 signaling during embryogenesis. In conclusion, we have uncovered a novel function of GARP in positively regulating TGFβ3 activation and function. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    HIV-related stigma hampers treatment and prevention efforts worldwide. Effective interventions to counter HIV-related stigma are greatly needed. Although the "contact hypothesis" suggests that personal contact with persons living with HIV (PLHIV) may reduce stigmatizing attitudes in the general population, empirical evidence in support of this hypothesis is lacking. Our aim was to estimate the association between personal contact with PLHIV and HIV-related stigma among the general population of sub-Saharan Africa. Social distance and anticipated stigma were operationalized using standard HIV-related stigma questions contained in the Demographic and Health Surveys and AIDS Indicator Surveys of 26 African countries between 2003 and 2008. We fitted multivariable logistic regression models with country-level fixed effects, specifying social distance as the dependent variable and personal contact with PLHIV as the primary explanatory variable of interest. We analyzed data from 206,717 women and 91,549 men living in 26 sub-Saharan African countries. We estimated a statistically significant negative association between personal contact with PLHIV and desires for social distance (adjusted odds ratio [AOR] = 0.80; p  interventions should be developed and tested to reduce the stigma of HIV.

    The efficacy of lapatinib versus trastuzumab combined with taxanes in the first-line setting of human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (BC) is unknown. The MA.31 trial compared a combination of first-line anti-HER2 therapy (lapatinib or trastuzumab) and taxane therapy for 24 weeks, followed by the same anti-HER2 monotherapy until progression. Stratification was by prior (neo)adjuvant anti-HER2 therapy, prior (neo)adjuvant taxane, planned taxane, and liver metastases. The primary end point was intention-to-treat (ITT) progression-free survival (PFS), defined as time from random assignment to progression by RECIST (version 1.0) criteria, or death for patients with locally assessed HER2-positive tumors. The primary test statistic was a stratified log-rank test for noninferiority. PFS was also assessed for patients with centrally confirmed HER2-positive tumors. From July 17, 2008, to December 1, 2011, 652 patients were accrued from 21 countries, resulting in 537 patients with centrally confirmed HER2-positive tumors. Median follow-up was 21.5 months. Median ITT PFS was 9.0 months with lapatinib and 11.3 months with trastuzumab. By ITT analysis, PFS was inferior for lapatinib compared with trastuzumab, with a stratified hazard ratio (HR) of 1.37 (95% CI, 1.13 to 1.65; P = .001). In patients with centrally confirmed HER2-positive tumors, median PFS was 9.1 months with lapatinib and 13.6 months with trastuzumab (HR, 1.48; 95% CI, 1.20 to 1.83; P < .001). More grade 3 or 4 diarrhea and rash were observed with lapatinib (P < .001). PFS results were supported by the secondary end point of overall survival, with an ITT HR of 1.28 (95% CI, 0.95 to 1.72; P = .11); in patients with centrally confirmed HER2-positive tumors, the HR was 1.47 (95% CI, 1.03 to 2.09; P = .03). As first-line therapy for HER2-positive metastatic BC, lapatinib combined with taxane was associated with shorter PFS and more toxicity compared with trastuzumab

    Gene expression profile‑based taxonomy of breast cancer (BC) has been described as a significant breakthrough in comprehending the differences in the origin and behavior of cancer to allow individually tailored therapeutic approaches. In line with this, we hypothesized that the gene expression profile of histologically normal epithelium (HNEpi) could harbor certain genetic abnormalities predisposing breast tissue cells to develop human epidermal growth factor receptor 2 (HER2)‑positive BC. Thus, the aim of the present study was to assess gene expression in normal and BC tissue (BCTis) from patients with BC in order to establish its value as a potential diagnostic marker for cancer development. An array study evaluating a panel of 84 pathway‑ and disease‑specific genes in HER2‑positive BC and tumor‑adjacent HNEpi was performed using quantitative polymerase chain reaction in 12 patients using microdissected samples from frozen tissue. Common prognostic and predictive parameters of BC were assessed by immunohistochemistry and in situ hybridization. In the BCTis and HNEpi samples of 12 HER2‑positive subjects with BC, the expression of 2,016 genes was assessed. A total of 39.3% of genes were deregulated at a minimal two‑fold deregulation rate and 10.7% at a five‑fold deregulation rate in samples of HNEpi or BCTis. Significant differences in gene expression between BCTis and HNEpi samples were revealed for BCL2L2, CD44, CTSD, EGFR, ERBB2, ITGA6, NGFB, RPL27, SCBG2A1 and SCGB1D2 genes (Pbreast tissue revealed gene expression abnormalities that may represent potential markers of increased risk for HER2‑positive malignant transformation of breast tissue, and may be able to be employed as predictors of prognosis.

    Neratinib is a potent irreversible pan-tyrosine kinase inhibitor with antitumor activity and acceptable tolerability in patients with human epidermal growth factor receptor 2 (HER2) -positive breast cancer. A multinational, open-label, phase I/II trial was conducted to determine the maximum-tolerated dose (MTD) of neratinib plus capecitabine in patients with solid tumors (part one) and to evaluate the safety and efficacy of neratinib plus capecitabine in patients with HER2-positive metastatic breast cancer (part two). Part one was a 3 + 3 dose-escalation study in which patients with advanced solid tumors received oral neratinib once per day continuously plus capecitabine twice per day on days 1 to 14 of a 21-day cycle at predefined dose levels. In part two, patients with trastuzumab-pretreated HER2-positive metastatic breast cancer received neratinib plus capecitabine at the MTD. The primary end point in part two was objective response rate (ORR). In part one (n = 33), the combination of neratinib 240 mg per day plus capecitabine 1,500 mg/m(2) per day was defined as the MTD, which was further evaluated in part 2 (n = 72). The most common drug-related adverse events were diarrhea (88%) and palmar-plantar erythrodysesthesia syndrome (48%). In part two, the ORR was 64% (n = 39 of 61) in patients with no prior lapatinib exposure and 57% (n = 4 of 7) in patients previously treated with lapatinib. Median progression-free survival was 40.3 and 35.9 weeks, respectively. Neratinib in combination with capecitabine had a manageable toxicity profile and showed promising antitumor activity in patients with HER2-positive metastatic breast cancer pretreated with trastuzumab and lapatinib. © 2014 by American Society of Clinical Oncology.

    Today's InGaN-based white LEDs still suffer from a significant efficiency reduction at elevated current densities, the so-called "Droop". Core-shell microrods, with quantum wells (QWs) covering their entire surface, enable a tremendous increase in active area scaling with the rod's aspect ratio. Enlarging the active area on a given footprint area is a viable and cost effective route to mitigate the droop by effectively reducing the local current density. Microrods were grown in a large volume metal-organic vapor phase epitaxy (MOVPE) reactor on GaN-on-sapphire substrates with a thin, patterned SiO2 mask for position control. Out of the mask openings, pencil-shaped n-doped GaN microrod cores were grown under conditions favoring 3D growth. In a second growth step, these cores are covered with a shell containing a quantum well and a p-n junction to form LED structures. The emission from the QWs on the different facets was studied using resonant temperature-dependent photoluminescence (PL) and cathodoluminescence (CL) measurements. The crystal quality of the structures was investigated by transmission electron microscopy (TEM) showing the absence of extended defects like threading dislocations in the 3D core. In order to fabricate LED chips, dedicated processes were developed to accommodate for the special requirements of the 3D geometry. The electrical and optical properties of ensembles of tens of thousands microrods connected in parallel are discussed.

    Full Text Available The current management of thalassemia includes regular transfusion programs and chelation therapy. It is important that physicians be aware that endocrine abnormalities frequently develop mainly in those patients with significant iron overload due to poor compliance to treatment, particularly after the age of 10 years. Since the quality of life of thalassemia patients is a fundamental aim, it is vital to monitor carefully their growth and pubertal development in order to detect abnormalities and to initiate appropriate and early treatment. Abnormalities should be identified and treatment initiated in consultation with a pediatric or an adult endocrinologist and managed accordingly. Appropriate management shall put in consideration many factors such as age, severity of iron overload, presence of chronic liver disease, thrombophilia status, and the presence of psychological problems. All these issues must be discussed by the physician in charge of the patient′s care, the endocrinologist and the patient himself. Because any progress in research in the field of early diagnosis and management of growth disorders and endocrine complications in thalassemia should be passed on to and applied adequately to all those suffering from the disease, on the 8 May 2009 in Ferrara, the International Network on Endocrine Complications in Thalassemia (I-CET was founded in order to transmit the latest information on these disorders to the treating physicians. The I-CET position statement outlined in this document applies to patients with transfusion-dependent thalassemia major to help physicians to anticipate, diagnose, and manage these complications properly.

    Background With the expected increase in the numbers of persons with dementia, providing timely, adequate, and affordable care and support is challenging. Assistive and health technologies may be a valuable contribution in dementia care, but new challenges may emerge. Objective The aim of our study was to review the state of the art of technologies for persons with dementia regarding issues on development, usability, effectiveness and cost-effectiveness, deployment, and ethics in 3 fields of application of technologies: (1) support with managing everyday life, (2) support with participating in pleasurable and meaningful activities, and (3) support with dementia health and social care provision. The study also aimed to identify gaps in the evidence and challenges for future research. Methods Reviews of literature and expert opinions were used in our study. Literature searches were conducted on usability, effectiveness and cost-effectiveness, and ethics using PubMed, Embase, CINAHL, and PsycINFO databases with no time limit. Selection criteria in our selected technology fields were reviews in English for community-dwelling persons with dementia. Regarding deployment issues, searches were done in Health Technology Assessment databases. Results According to our results, persons with dementia want to be included in the development of technologies; there is little research on the usability of assistive technologies; various benefits are reported but are mainly based on low-quality studies; barriers to deployment of technologies in dementia care were identified, and ethical issues were raised by researchers but often not studied. Many challenges remain such as including the target group more often in development, performing more high-quality studies on usability and effectiveness and cost-effectiveness, creating and having access to high-quality datasets on existing technologies to enable adequate deployment of technologies in dementia care, and ensuring that ethical

    Full Text Available High-risk human papillomavirus (HR-HPV has been recognized as a major causative agent for cervical cancer. Upon HPV infection, early genes E6 and E7 play important roles in maintaining malignant phenotype of cervical cancer cells. By using clustered regularly interspaced short palindromic repeats- (CRISPR- associated protein system (CRISPR/Cas system, a widely used genome editing tool in many organisms, to target HPV16-E7 DNA in HPV positive cell lines, we showed for the first time that the HPV16-E7 single-guide RNA (sgRNA guided CRISPR/Cas system could disrupt HPV16-E7 DNA at specific sites, inducing apoptosis and growth inhibition in HPV positive SiHa and Caski cells, but not in HPV negative C33A and HEK293 cells. Moreover, disruption of E7 DNA directly leads to downregulation of E7 protein and upregulation of tumor suppressor protein pRb. Therefore, our results suggest that HPV16-E7 gRNA guided CRISPR/Cas system might be used as a therapeutic strategy for the treatment of cervical cancer.

    To provide formal expert consensus-based recommendations to practicing oncologists and others on the management of brain metastases for patients with human epidermal growth factor receptor 2 (HER2) -positive advanced breast cancer. The American Society of Clinical Oncology (ASCO) convened a panel of medical oncology, radiation oncology, guideline implementation, and advocacy experts and conducted a systematic review of the literature. When that failed to yield sufficiently strong quality evidence, the Expert Panel undertook a formal expert consensus-based process to produce these recommendations. ASCO used a modified Delphi process. The panel members drafted recommendations, and a group of other experts joined them for two rounds of formal ratings of the recommendations. No studies or existing guidelines met the systematic review criteria; therefore, ASCO conducted a formal expert consensus-based process. Patients with brain metastases should receive appropriate local therapy and systemic therapy, if indicated. Local therapies include surgery, whole-brain radiotherapy, and stereotactic radiosurgery. Treatments depend on factors such as patient prognosis, presence of symptoms, resectability, number and size of metastases, prior therapy, and whether metastases are diffuse. Other options include systemic therapy, best supportive care, enrollment onto a clinical trial, and/or palliative care. Clinicians should not perform routine magnetic resonance imaging (MRI) to screen for brain metastases, but rather should have a low threshold for MRI of the brain because of the high incidence of brain metastases among patients with HER2-positive advanced breast cancer. © 2014 by American Society of Clinical Oncology.

    Recent evidence suggests that androgen receptor (AR) splice variants, including AR-V7, play a pivotal role in resistance to androgen blockade in prostate cancer treatment. The development of new therapeutic agents that can suppress the transcriptional activities of AR splice variants has been anticipated as the next generation treatment of castration-resistant prostate cancer. High-throughput screening of AR-V7 signaling inhibitors was performed using an AR-V7 reporter system. The effects of a glycogen synthase kinase-3 (GSK3) inhibitor, LY-2090314, on endogenous AR-V7 signaling were evaluated in an AR-V7-positive cell line, JDCaP-hr, by quantitative reverse transcription polymerase chain reaction. The relationship between AR-V7 signaling and β-catenin signaling was assessed using RNA interference. The effect of LY-2090314 on cell growth in various prostate cancer cell lines was also evaluated. We identified GSK3 inhibitors as transcriptional suppressors of AR-V7 using a high-throughput screen with an AR-V7 reporter system. LY-2090314 suppressed the reporter activity and endogenous AR-V7 activity in JDCaP-hr cells. Because silencing of β-catenin partly rescued the suppression, it was evident that the suppression was mediated, at least partially, via the activation of β-catenin signaling. AR-V7 signaling and β-catenin signaling reciprocally regulate each other in JDCaP-hr cells, and therefore, GSK3 inhibition can repress AR-V7 transcriptional activity by accumulating intracellular β-catenin. Notably, LY-2090314 selectively inhibited the growth of AR-V7-positive prostate cancer cells in vitro. Our findings demonstrate the potential of GSK3 inhibitors in treating advanced prostate cancer driven by AR splice variants. In vivo evaluation of AR splice variant-positive prostate cancer models will help illustrate the overall significance of GSK3 inhibitors in treating prostate cancer. © 2017 Wiley Periodicals, Inc.

    Human epidermal growth factor receptor 2 (HER2) overexpression was associated with locoregional recurrence (LRR) in the preadjuvant trastuzumab era. This study aimed to examine the effect of trastuzumab on LRR in mastectomy patients and whether it varied with postmastectomy radiation (PMRT). From the authors' institutional database, 501 women with stages I-III HER2-positive breast cancer who underwent mastectomy from 1998 to 2007 were identified. A landmark analysis was performed to compare two cohorts: 170 women who received trastuzumab and 281 who did not. Kaplan-Meier methods were used to estimate locoregional recurrence-free survival (LRRFS). A propensity score analysis was used to balance the treatment groups with respect to multiple covariates. Analogous methods were used to study the effect of PMRT. The women in the trastuzumab group were more likely to be node positive and to receive systemic therapy or PMRT (p < 0.01). The 5-year LRRFS was 98 % in the trastuzumab troup versus 94 % in the no trastuzumab group [hazard ratio (HR) 0.31; 95 % confidence interval (CI) 0.09-1.09; p = 0.07]. After adjustment for multiple covariates, including receipt of chemotherapy and PMRT, trastuzumab decreased LRR rates (HR 0.21; 95 % CI 0.04-0.94; p = 0.04). Among the women who received PMRT, trastuzumab reduced the 5-year LRR rate (0 vs 5 %; p = 0.06). Among those who did not receive PMRT, trastuzumab did not significantly decrease LRR (3 vs 6 %; p = 0.26). High rates of locoregional control (5-year rate, 98 %) were observed among patients who received trastuzumab and mastectomy ± PMRT. Trastuzumab decreased LRR in HER2-positive women who received mastectomy and PMRT, suggesting that the largest benefit is seen in a higher-risk subset of patients.

    With the expected increase in the numbers of persons with dementia, providing timely, adequate, and affordable care and support is challenging. Assistive and health technologies may be a valuable contribution in dementia care, but new challenges may emerge. The aim of our study was to review the state of the art of technologies for persons with dementia regarding issues on development, usability, effectiveness and cost-effectiveness, deployment, and ethics in 3 fields of application of technologies: (1) support with managing everyday life, (2) support with participating in pleasurable and meaningful activities, and (3) support with dementia health and social care provision. The study also aimed to identify gaps in the evidence and challenges for future research. Reviews of literature and expert opinions were used in our study. Literature searches were conducted on usability, effectiveness and cost-effectiveness, and ethics using PubMed, Embase, CINAHL, and PsycINFO databases with no time limit. Selection criteria in our selected technology fields were reviews in English for community-dwelling persons with dementia. Regarding deployment issues, searches were done in Health Technology Assessment databases. According to our results, persons with dementia want to be included in the development of technologies; there is little research on the usability of assistive technologies; various benefits are reported but are mainly based on low-quality studies; barriers to deployment of technologies in dementia care were identified, and ethical issues were raised by researchers but often not studied. Many challenges remain such as including the target group more often in development, performing more high-quality studies on usability and effectiveness and cost-effectiveness, creating and having access to high-quality datasets on existing technologies to enable adequate deployment of technologies in dementia care, and ensuring that ethical issues are considered an important topic

    Compliance with CPAP treatment for OSAS is not reliably predicted by the severity of symptoms or physiological variables. We examined a range of factors which could be measured before CPAP initiation to look for predictors of compliance. This was a prospective cohort-study of CPAP treatment for OSAS, recording; socio-economic status, education, type D personality and clinician's prediction of compliance. We recruited 265 subjects, of whom 221 were still using CPAP at 6 months; median age 53 years, M: F, 3.4:1, ESS 15 and pre-treatment ODI 21/h. Median compliance at 6 months was 5.6 (3.4- 7.1) hours/night with 73.3% of subjects using CPAP ≥4 h/night. No association was found between compliance and different socio-economic classes for people in work, type D personality, education level, sex, age, baseline ESS or ODI. The clinician's initial impression could separate groups of good and poor compliers but had little predictive value for individual patients. Compared to subjects who were working, those who were long term unemployed had a lower CPAP usage and were more likely to use CPAP < 4 h a night (OR 4.6; p value 0.011). A high Beck Depression Index and self-reported anxiety also predicted poor compliance. In our practice there is no significant association between CPAP compliance with socio-economic status, education or personality type. Long term unemployed or depressed individuals may need more intensive support to gain the optimal benefit from CPAP.

    The tomato leaf miner, Tuta absoluta (Meyrick), is a devastating pest of tomato worldwide. One of the control measures of T. absoluta is the use of biological control agents, such as Trichogramma wasps. Interactions between natural enemies and insect pests may be affected by application of fertilizers, because changes in plant quality through the fertilizer application may therefore affect herbivore characteristics and suitability of them to parasitism. Laboratory tests were carried out to evaluate the life table parameters of Trichogramma brassicae Bezdenko on T. absoluta eggs reared on tomato plants treated either with vermicompost (40%), humic fertilizer (2 g/kg soil), or control (suitable mixture of field soil and sand). Population growth parameters of T. brassicae were affected by fertilizer treatments. Significant differences were found for immature life period and total fecundity of T. brassicae on the treatments. Differences of intrinsic rate of natural increase (r m ), finite rate of increase (λ), net reproductive rate (R 0 ), mean generation time (T), and doubling time (DT) of T. brassicae among treatments were also significant. The lowest values of r m , λ, and R 0 were recorded for T. brassicae developed on T. absoluta eggs on control treatment, whereas the highest values of these parameters were observed on 2 g/kg humic fertilizer. Furthermore, T. brassicae had the shortest T and DT values on 2 g/kg humic fertilizer and 40% vermicompost treatments. Our results showed that application of humic fertilizer and vermicompost could positively affect population growth parameters of T. brassicae on eggs of T. absoluta fed on tomato plants.

    Evidence-based treatments for metastatic, human epidermal growth factor receptor 2 (HER2)-positive breast cancer in the CNS are limited. Neratinib is an irreversible inhibitor of erbB1, HER2, and erbB4, with promising activity in HER2-positive breast cancer; however, its activity in the CNS is unknown. We evaluated the efficacy of treatment with neratinib in patients with HER2-positive breast cancer brain metastases in a multicenter, phase II open-label trial. Eligible patients were those with HER2-positive brain metastases (≥ 1 cm in longest dimension) who experienced progression in the CNS after one or more line of CNS-directed therapy, such as whole-brain radiotherapy, stereotactic radiosurgery, and/or surgical resection. Patients received neratinib 240 mg orally once per day, and tumors were assessed every two cycles. The primary endpoint was composite CNS objective response rate (ORR), requiring all of the following: ≥ 50% reduction in volumetric sum of target CNS lesions and no progression of non-target lesions, new lesions, escalating corticosteroids, progressive neurologic signs/symptoms, or non-CNS progression--the threshold for success was five of 40 responders. Forty patients were enrolled between February 2012 and June 2013; 78% of patients had previous whole-brain radiotherapy. Three women achieved a partial response (CNS objective response rate, 8%; 95% CI, 2% to 22%). The median number of cycles received was two (range, one to seven cycles), with a median progression-free survival of 1.9 months. Five women received six or more cycles. The most common grade ≥ 3 event was diarrhea (occurring in 21% of patients taking prespecified loperamide prophylaxis and 28% of those without prophylaxis). Patients in the study experienced a decreased quality of life over time. Although neratinib had low activity and did not meet our threshold for success, 12.5% of patients received six or more cycles.

    Nutrigenetics considers the influence of individual genetic variation on differences in response to dietary components, nutrient requirements and predisposition to disease. Nutrigenomics involves the study of interactions between the genome and diet, including how nutrients affect the transcription and translation process plus subsequent proteomic and metabolomic changes, and also differences in response to dietary factors based on the individual genetic makeup. Personalized characteristics such as age, gender, physical activity, physiological state and social status, and special conditions such as pregnancy and risk of disease can inform dietary advice that more closely meets individual needs. Precision nutrition has a promising future in treating the individual according to their phenotype and genetic characteristics, aimed at both the treatment and prevention of disease. However, many aspects are still in progress and remain as challenges for the future of nutrition. The integration of the human genotype and microbiome needs to be better understood. Further advances in data interpretation tools are also necessary, so that information obtained through newer tests and technologies can be properly transferred to consumers. Indeed, precision nutrition will integrate genetic data with phenotypical, social, cultural and personal preferences and lifestyles matters to provide a more individual nutrition, but considering public health perspectives, where ethical, legal and policy aspects need to be defined and implemented. © 2016 S.

    c-Met is a tyrosine kinase receptor for hepatocyte growth factor/scatter factor (HGF/SF), and both c-Met and its ligand are expressed in a variety of tissues. C-Met/HGF/SF signaling is essential for normal embryogenesis, organogenesis, and tissue regeneration. Abnormal c-Met/HGF/SF signaling has been demonstrated in different tumors and linked to aggressive and metastatic tumor phenotypes. In vitro and in vivo studies have demonstrated inhibition of c-Met/HGF/SF signaling by the small-molecule inhibitor PHA665752. This study investigated c-Met and HGF expression in two neuroblastoma (NBL) cell lines and tumor tissue from patients with NBL, as well as the effects of PHA665752 on growth and motility of NBL cell lines. The effect of the tumor suppressor protein PTEN on migration and proliferation of tumor cells treated with PHA665752 was also evaluated. Expression of c-Met and HGF in NBL cell lines SH-EP and SH-SY5Y and primary tumor tissue was assessed by immunohistochemistry and quantitative RT-PCR. The effect of PHA665752 on c-Met/HGF signaling involved in NBL cell proliferation and migration was evaluated in c-Met-positive cells and c-Met-transfected cells. The transwell chemotaxis assay and the MTT assay were used to measure migration and proliferation/cell-survival of tumor cells, respectively. The PPAR-γ agonist rosiglitazone was used to assess the effect of PTEN on PHA665752-induced inhibition of NBL cell proliferation/cell-survival and migration High c-Met expression was detected in SH-EP cells and primary tumors from patients with advanced-stage disease. C-Met/HGF signaling induced both migration and proliferation of SH-EP cells. Migration and proliferation/cell-survival were inhibited by PHA665752 in a dose-dependent manner. We also found that induced overexpression of PTEN following treatment with rosiglitazone significantly enhanced the inhibitory effect of PHA665752 on NBL-cell migration and proliferation. c-Met is highly expressed in most tumors from

    Living plant neighbours, but also their dead aboveground remains (i.e. litter), may individually exert negative or positive effects on plant recruitment. Although living plants and litter co-occur in most ecosystems, few studies have addressed their combined effects, and conclusions are ambivalent. Therefore, we examined the response in terms of seedling emergence and growth of herbaceous grassland and forest species to different litter types and amounts and the presence of competitors. We conducted a pot experiment testing the effects of litter type (grass, oak), litter amount (low, medium, high) and interspecific competition (presence or absence of four Festuca arundinacea individuals) on seedling emergence and biomass of four congeneric pairs of hemicryptophytes from two habitat types (woodland, grassland). Interactions between litter and competition were weak. Litter presence increased competitor biomass. It also had positive effects on seedling emergence at low litter amounts and negative effects at high litter amounts, while competition had no effect on seedling emergence. Seedling biomass was negatively affected by the presence of competitors, and this effect was stronger in combination with high amounts of litter. Litter affected seedling emergence while competition determined the biomass of the emerged individuals, both affecting early stages of seedling recruitment. High litter accumulation also reduced seedling biomass, but this effect seemed to be additive to competitor effects. This suggests that live and dead plant mass can affect species recruitment in natural systems, but the mechanisms by which they operate and their timing differ. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Ecotropic viral integration site 1 (Evi1) is a transcription factor that is highly expressed in hematopoietic stem cells and is crucial for their self-renewal capacity. Aberrant expression of Evi1 is observed in 5% to 10% of de novo acute myeloid leukemia (AML) patients and predicts poor prognosis, reflecting multiple leukemogenic properties of Evi1. Here, we show that thrombopoietin (THPO) signaling is implicated in growth and survival of Evi1-expressing cells using a mouse model of Evi1 leukemia. We first identified that the expression of megakaryocytic surface molecules such as ITGA2B (CD41) and the THPO receptor, MPL, positively correlates with EVI1 expression in AML patients. In agreement with this finding, a subpopulation of bone marrow and spleen cells derived from Evi1 leukemia mice expressed both CD41 and Mpl. CD41(+) Evi1 leukemia cells induced secondary leukemia more efficiently than CD41(-) cells in a serial bone marrow transplantation assay. Importantly, the CD41(+) cells predominantly expressing Mpl effectively proliferated and survived on OP9 stromal cells in the presence of THPO via upregulating BCL-xL expression, suggesting an essential role of the THPO/MPL/BCL-xL cascade in enhancing the progression of Evi1 leukemia. These observations provide a novel aspect of the diverse functions of Evi1 in leukemogenesis. © 2014 by The American Society of Hematology.

    Azospirillum brasilense has significance as a growth promoter in plants of commercial interest. Two industrial native strains (Start and Calf), used as a part of an inoculant formulation in Mexico during the last 15 years, were incubated in laboratory-scale pneumatic bioreactors at different aeration rates. In both strains, the positive effect of decreased aeration was observed. At the lowest (0.1 vvm, air volume/liquid volume×minute), the highest biomass were obtained for Calf (7.8 × 10(10)CFU/ml), and Start (2.9 × 10(9)CFU/ml). These were higher in one magnitude order compared to cultures carried out at 0.5 vvm, and two compared to those at 1.0 vvm. At lower aeration, both stereoisomeric forms of malic acid were consumed, but at higher aeration, just L-malate was consumed. A reduction in aeration allows an increase of the shelf life and the microorganism saved higher concentrations of polyhydroxybutyrate. The selected fermentation conditions are closely related to those prevalent in large-scale bioreactors and offer the possibility of achieving high biomass titles with high shelf life at a reduced costs, due to the complete use of a carbon source at low aeration of a low cost raw material as DL-malic acid mixture in comparison with the L-malic acid stereoisomer.

    Full Text Available Background: Thalassemia patients who undergo life-long recurrent blood transfusion will experience iron overload in various organs including the liver and possibly suffer from chronic hepatitis C infection which may lead to liver impairment. The liver produces hepcidin, a hormone which plays role in the regulation of iron level in the blood. Various factors may influence hepcidin level in the blood. Chronic hepatitis C causes iron overload and liver impairment. Liver impairment and haemolytic anaemia due to haemoglobinopathy will suppress hepcidin production. Anaemia stimulates growth differentiation factor 15 (GDF-15 to increase erythropoiesis and suppress hepcidin production. Iron overload causes increase in hepcidin level. Presence of factors which decrease or increase hepcidin production will express various levels of hepcidin. This study aimed to identify the expression of hepcidin and GDF-15 levels in thalassemia patients with iron overload and positive anti-HCV. Information on hepcidin and GDF-15 levels are beneficial in the management of iron overload in thalassemia with positive anti-HCV. Method: This study was a descriptive analytic study in thalassemia patients who had received recurrent blood transfusion ≥ 12 times, suffered from iron overload (transferrin saturation > 55% and ferritin > 1,000 ng/mL, which consisted of 31 individuals with positive anti-HCV and 27 individuals with negative anti-HCV.

    This article deals with critical psychic transformation in a schizoid personality disorder that evolves in an object relations psychoanalysis in which "developmental mourning" plays a central role. Within a mourning process that allows for the grieving of loss related to arrested separation-individuation development, the analysand confronts the existential grief of regret that had always unconsciously haunted her. The unconscious guilt related to the existential grief of regret had caused much dissociation of self-experience and affect states. The analysand acknowledges her own part in the destruction of primal and current relationships after the traumatic impact of her early life is understood. This allows her to repair current relationships, both within her internal and external worlds so that she can open to capacities for love and creativity. The analysand's courage to consciously grapple with her regret (loss and guilt combined) allows her to relinquish self-sabotaging character defenses such as contempt and emotional withdrawl. Consequently, a second marriage is salvaged and enriched, and the analysand's relationship with her two children is dramatically improved.

  19. [Respect for self-determination and use of coercion in the treatment of mentally ill persons: an ethical position statement of the DGPPN].

    Science.gov (United States)

    2014-11-01

    Respect for patient self-determination is a central ethical principle of medical care. Every person has the right to make decisions regarding his or her health autonomously, even if these decisions appear irrational to third parties. Free and informed consent is the necessary prerequisite for every diagnostic and therapeutic procedure. A patient's ability for self-determination is one requirement for valid consent. In illness, the ability for self-determination may be limited or absent in individual cases. An ethical dilemma arises if severely ill patients who are unable to make autonomous decisions put their health at significant risk and refuse medical procedures in this situation. While non-treatment can be severely detrimental to health, forced procedures can result in traumatization and can damage the relationship of trust between the doctor and patient. The dilemma is intensified in cases of danger to others. In these difficult situations doctors, therapists and nursing staff require ethical guidance for the professional conduct. The primary objective thereby is to avoid coercion. For this purpose recommendations for medical practice are formulated that can reduce the use of forced procedures (e.g. de-escalation procedures, communication competency, clinical ethics counseling, treatment agreements and patient living wills) or if they are unavoidable, that allow them to be conducted in an ethically and legally appropriate way. Further and continued education must pay greater attention to this ethical objective; therefore, for ethical reasons adequate personnel, spatial and structural are vital in hospitals.

    Chemotherapy with trastuzumab is widely used for patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer, but a significant number of patients with the tumor fail to respond, or relapse. The mechanisms of recurrence and biomarkers that indicate the response to the chemotherapy and outcome are not fully investigated. Genomic alterations were analyzed using single-nucleotide polymorphism arrays in 46 HER2 immunohistochemistry (IHC) 3+ or 2+/fluorescent in situ hybridization (FISH)+ breast cancers that were treated with neoadjuvant chemotherapy with paclitaxel, cyclophosphamid, epirubicin, fluorouracil, and trastuzumab. Patients were classified into two groups based on presence or absence of alterations of 65 cancer-associated genes, and the two groups were further classified into four groups based on genomic HER2 copy numbers or hormone receptor status (HR+/−). Pathological complete response (pCR) and relapse-free survival (RFS) rates were compared between any two of the groups. The pCR rate was 54% in 37 patients, and the RFS rate at 3 years was 72% (95% CI, 0.55-0.89) in 42 patients. The analysis disclosed 8 tumors with nonamplified HER2 and 38 tumors with HER2 amplification, indicating the presence of discordance in tumors diagnosed using current HER2 testing. The 8 patients showed more difficulty in achieving pCR (P=0.019), more frequent relapse (P=0.018), and more frequent alterations of genes in the PI3K pathway (P=0.009) than the patients with HER2 amplification. The alterations of the PI3K and estrogen receptor (ER) pathway genes generally indicated worse RFS rates. The prognostic significance of the alterations was shown in patients with a HR+ tumor, but not in patients with a HR- tumor when divided. Alterations of the PI3K and ER pathway genes found in patients with a HR+ tumor with poor outcome suggested that crosstalk between the two pathways may be involved in resistance to the current chemotherapy with trastuzumab.

    Cotargeting the mammalian target of rapamycin pathway and estrogen receptor may prevent or delay endocrine resistance in patients receiving first-line treatment for advanced breast cancer. To investigate the combination of everolimus plus endocrine therapy in first-line and second-line treatment settings for postmenopausal women with estrogen receptor-positive, human epidermal growth receptor 2-negative advanced breast cancer. In the multicenter, open-label, single-arm, phase 2 BOLERO-4 (Breast Cancer Trials of Oral Everolimus) clinical trial, 245 patients were screened for eligibility; 202 were enrolled between March 7, 2013, and December 17, 2014. A median follow-up of 29.5 months had been achieved by the data cutoff date (December 17, 2016). Patients received first-line treatment with everolimus, 10 mg/d, plus letrozole, 2.5 mg/d. Second-line treatment with everolimus, 10 mg/d, plus exemestane, 25 mg/d, was offered at the investigator's discretion upon initial disease progression. The primary end point was investigator-assessed progression-free survival in the first-line setting per Response Evaluation Criteria in Solid Tumors, version 1.0. Safety was assessed in patients who received at least 1 dose of study medication and at least 1 postbaseline safety assessment. A total of 202 women treated in the first-line setting had a median age of 64.0 years (interquartile range, 58.0-70.0 years) with metastatic (194 [96.0%]) or locally advanced (8 [4.0%]) breast cancer. Median progression-free survival was 22.0 months (95% CI, 18.1-25.1 months) with everolimus and letrozole. Median overall survival was not reached; 24-month estimated overall survival rate was 78.7% (95% CI, 72.1%-83.9%). Fifty patients started second-line treatment; median progression-free survival was 3.7 months (95% CI, 1.9-7.4 months). No new safety signals were observed. In the first-line setting, the most common all-grade adverse event was stomatitis (139 [68.8%]); the most common grade 3 to 4

    Full Text Available The H19/Igf2 imprinting control region (ICR functions as an insulator exclusively in the unmethylated maternal allele, where enhancer-blocking by CTCF protein prevents the interaction between the Igf2 promoter and the distant enhancers. DNA methylation inhibits CTCF binding in the paternal ICR allele. Two copies of the chicken β-globin insulator (ChβGI(2 are capable of substituting for the enhancer blocking function of the ICR. Insulation, however, now also occurs upon paternal inheritance, because unlike the H19 ICR, the (ChβGI(2 does not become methylated in fetal male germ cells. The (ChβGI(2 is a composite insulator, exhibiting enhancer blocking by CTCF and chromatin barrier functions by USF1 and VEZF1. We asked the question whether these barrier proteins protected the (ChβGI(2 sequences from methylation in the male germ line.We genetically dissected the ChβGI in the mouse by deleting the binding sites USF1 and VEZF1. The methylation of the mutant versus normal (ChβGI(2 significantly increased from 11% to 32% in perinatal male germ cells, suggesting that the barrier proteins did have a role in protecting the (ChβGI(2 from methylation in the male germ line. Contrary to the H19 ICR, however, the mutant (mChβGI(2 lacked the potential to attain full de novo methylation in the germ line and to maintain methylation in the paternal allele in the soma, where it consequently functioned as a biallelic insulator. Unexpectedly, a stricter enhancer blocking was achieved by CTCF alone than by a combination of the CTCF, USF1 and VEZF1 sites, illustrated by undetectable Igf2 expression upon paternal transmission.In this in vivo model, hypomethylation at the ICR position together with fetal growth retardation mimicked the human Silver-Russell syndrome. Importantly, late fetal/perinatal death occurred arguing that strict biallelic insulation at the H19/Igf2 ICR position is not tolerated in development.

    The CLEOPATRA (Clinical Evaluation of Trastuzumab and Pertuzumab) study demonstrated superior progression-free survival (PFS) and overall survival when pertuzumab was added to trastuzumab and docetaxel. Paclitaxel given once per week is effective and less toxic than docetaxel. We performed a phase II study to evaluate the efficacy and safety of pertuzumab and trastuzumab with paclitaxel given once per week. Patients with metastatic human epidermal growth factor receptor 2-positive breast cancer with zero to one prior therapy were enrolled. Treatment consisted of paclitaxel 80 mg/m(2) once per week plus trastuzumab (8 mg/kg loading dose → 6 mg/kg) once every 3 weeks plus pertuzumab (840 mg loading dose → 420 mg) once every 3 weeks, all given intravenously. The primary end point was 6-month PFS assessed by Kaplan-Meier methods. From January 2011 to December 2013, we enrolled 69 patients: 51 (74%) and 18 (26%) treated in first- and second-line metastatic settings, respectively. At a median follow-up of 21 months (range, 3 to 38 months), 6-month PFS was 86% (95% CI, 75% to 92%). The median PFS was 19.5 months (95% CI, 14 to 26 months) overall. PFS was 24.2 months (95% CI, 14 months to not reached [NR]) and 16.4 months (95% CI, 8.5 months to NR) for those without and with prior treatment, respectively. At 1 year, Kaplan-Meier PFS was 70% (95% CI, 56% to 79%) overall, 71% (95% CI, 55% to 82%) for those without prior therapy, and 66% (95% CI, 40% to 83%) for those with prior therapy. Treatment was well-tolerated; there was no febrile neutropenia or symptomatic left ventricular systolic dysfunction. Paclitaxel given once per week with trastuzumab and pertuzumab is highly active and well tolerated and seems to be an effective alternative to docetaxel-based combination therapy. © 2014 by American Society of Clinical Oncology.

    This meta-analysis was designed to fully assess the curative effects of radiotherapy-based therapies for human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC). English articles were retrieved through searching Cochrane library, PubMed, and Embase databases updated to February 2017. Studies were selected based on the inclusion and exclusion criteria. The curative effects of radiotherapy-based therapies forHER2+ BC patients were assessed using hazard rates (HRs) or odds ratios (ORs), as well as their 95% confidence intervals (CIs). In addition, Egger test was used to assess publication bias, followed by sensitivity analysis. All statistic methods were conducted using R 3.12 software. A total of 9 eligible studies were included into this meta-analysis, which involved 2236 HER2+ BC patients. Egger test showed that the eligible studies had no publication bias (t = 2.198, P = .05918). Sensitivity analysis demonstrated that the results were stable. HER2+ BC patients in radiotherapy group had lower locoregional recurrences than those in other groups. Moreover, meta-analysis showed that no significant difference was found between HER2+ BC patients in radiotherapy group and other groups on the 1-year overall survival (P = 0.5263, I = 65.4%), 3-year overall survival (P = 0.4591, I = 0), and 5-year overall survival (P = 0.06277, I = 0). Radiotherapy-based therapies might have certain advantages in treating HER2+ BC patients.

    International guidelines for hormone-receptor-positive (HR(+)), human epidermal growth factor receptor-2 negative (HER2(-)) advanced breast cancer (BC) recommend sequential lines of hormonal therapy (HT), and only recommend chemotherapy for patients with extensive visceral involvement or rapidly progressive disease. This study evaluated actual physician-reported treatments for advanced BC in Europe. We conducted a retrospective chart review of 355 postmenopausal women with HR(+), HER2(-) advanced BC who progressed on ≥1 line of HT (adjuvant or advanced) and completed ≥1 line of chemotherapy (advanced). Treatment choice was evaluated for each line of therapy. Of 355 patients, 111 (31%) received first-line chemotherapy, whereas 218 (61%) and 26 (7%) switched from HT to chemotherapy in second and third line, respectively. More patients receiving first-line HT had bone metastases (73% vs 27% chemotherapy). Patients treated with first-line chemotherapy had more brain (12% vs 3% HT) or extensive liver (13% vs 6% HT) metastases. Subgroup analysis of 188 patients who received first-line HT and had de novo advanced BC or relapsed/recurrent disease more than 1 year after adjuvant therapy found that the majority (89%; n = 167) of these patients switched to chemotherapy in second line. However, among these 167 patients, 27% had no significant changes in metastases between first and second line. Among the 73% of patients who had significant changes in metastases, 20% had no brain metastases or extensive visceral disease. Our study suggests that the guideline-recommended use of multiple HT lines is open to interpretation and that optimal treatment for European postmenopausal women with HR(+), HER2(-) advanced BC who responded to HT may not be achieved.

    Healthcare resource utilization in breast cancer varies by disease characteristics and treatment choices. However, lack of clarity in guidelines can result in varied interpretation and heterogeneous treatment management and costs. In Europe, the extent of this variability is unclear. Therefore, evaluation of chemotherapy use and costs versus hormone therapy across Europe is needed. This retrospective chart review (N = 355) examined primarily direct costs for chemotherapy versus hormone therapy in postmenopausal women with hormone-receptor–positive (HR+), human epidermal growth factor receptor-2–negative (HER2–) advanced breast cancer across 5 European countries (France, Germany, The Netherlands, Belgium, and Sweden). Total direct costs across the first 3 treatment lines were approximately €10 000 to €14 000 lower for an additional line of hormone therapy-based treatment versus switching to chemotherapy-based treatment. Direct cost difference between chemotherapy-based and hormone therapy-based regimens was approximately €1900 to €2500 per month. Chemotherapy-based regimens were associated with increased resource utilization (managing side effects; concomitant targeted therapy use; and increased frequencies of hospitalizations, provider visits, and monitoring tests). The proportion of patients taking sick leave doubled after switching from hormone therapy to chemotherapy. These results suggest chemotherapy is associated with increased direct costs and potentially with increased indirect costs (lower productivity of working patients) versus hormone therapy in HR+, HER2– advanced breast cancer.

    Pathologic complete response after neoadjuvant chemotherapy (NACT) correlates with overall survival (OS) in primary breast cancer. A recently described staging system based on pre-treatment clinical stage (CS), final pathological stage (PS), estrogen receptor (ER) status and nuclear grade (NG) leads to a refined estimation of prognosis in unselected patients. Its performance in luminal type breast cancers has not been determined. This study investigates the clinical utility of this CPS+EG score when restricted to hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) patients and compares the results to a cohort of unselected patients. The CPS+EG score was calculated for 6637 unselected patients and 2454 patients with HR+/HER2- tumours who received anthracycline/taxane-based NACT within 8 prospective German trials. Five-year disease-free survival (DFS) and OS were 75.6% and 84.1% for the unselected cohort and 80.6% and 87.8% for the HR+/HER2- subgroup, respectively. The CPS+EG system distinguished different prognostic groups with 5-year DFS ranging from 0% to 91%. The CPS+EG system leads to an improved categorisation of patients by outcome compared to CS, PS, ER or NG alone. When applying the CPS+EG score to the HR+/HER2- subgroup, a shift to lower scores was observed compared to the overall population, but 5-year DFS and OS for the individual scores were identical to that observed in the overall population. In HR+/HER2- patients, the CPS+EG staging system retains its ability to facilitate a refined stratification of patients according to outcome. It can help to select candidates for post-neoadjuvant clinical trials in luminal breast cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The MicroPLB (personal locator beacon) is a search and rescue satellite-aided tracking (SARSAT) transmitter. When activated it emits a distress signal to a constellation of internationally operated satellites. The endangered person's identity and location anywhere on Earth is automatically forwarded to central monitoring stations around the world. It is accurate to within just a few meters. The user uses the device to download navigation data from a global positioning satellite receiver. After the download is complete, the MicroPLB functions as a self-locating beacon. Also, it is the only PLB to use a safe battery. In the past, other PLB devices have used batteries that have enough volatility to explode with extreme force. It was developed by Microwave Monolithic, Inc. through SBIR funding from Glenn Research Center and Goddard Space Flight Center.

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

  11. Hitting the road to adulthood: short-term personality development during a major life transition.

    Previous research suggests that normative life transitions have the potential to trigger personality maturation. But what exactly happens during such a transitional stage? The present study examined personality trait changes in a sample of 910 German high school students during their transition from school to adult life. Despite the short observation period of three semiannual measurements, growth curve analyses revealed significant mean-level changes in personality traits. These changes occurred primarily in a positive direction, were strongest for the trait of conscientiousness, and most pronounced in those students who were directly confronted with this transitional experience. Bivariate growth curve models indicated that individual differences in personality change were substantially associated with changes in students' investments into achievement behavior. Supporting socioanalytic perspectives on personality development, these findings can be discussed with respect to process approaches to personality change assuming that consistent behavioral changes might lead to personality change in a bottom-up fashion.

  13. Stress and personality.

    Lecic-Tosevski, D; Vukovic, O; Stepanovic, J

    2011-01-01

    Stress is an adaptation reaction of living organisms in response to internal or external threats to homeostasis. It is considered as a complex defence mechanism representing the final endpoint of numerous dynamic and interconnected factors of biological, psychological and social nature. Stress is not a simple, stimulus-response reaction, but the interaction between an individual and the environment, involving subjective perception and assessment of stressors, thus constituting a highly personalized process. Specific inherited characteristics, early experience in life, and particular, learned cognitive predispositions make individuals more or less susceptible to the effects of stressors. Resilience and vulnerability to stressors as well as intensity of stress response are greatly dependable on age, gender, intelligence, and numerous characteristics of personality, such as hardiness,locus of control, self-efficacy, self-esteem, optimism, hostility (component of type A personality)and type D traits (negative affectivity and social inhibition). To understand the relation between personality and stress, it is essential to recognize the impact of individual differences in the following four aspects: (1) choice or avoidance of environments that are associated with specific stressors, challenges or benefits, (2) way of interpreting a stressful situation and evaluating one's own abilities and capacities for proactive behaviour so as to confront or avoid it, (3) intensity of response to a stressor,and (4) coping strategies employed by the individual facing a stressful situation. Studies have recorded considerable consistency in coping strategies employed to confront stressful situations, independentlyof situational factors and in connection with permanent personality and temperamental traits,such as neuroticism, extraversion, sense of humour, persistence, fatalism, conscientiousness, andopenness to experience. Positive affect has been associated with positive reappraisal

    To evaluate the diagnostic significance of the blood disappearance rate of {sup 198}Au-colloid and to evaluate the change of hepatic blood flow during position change from supine to erect, we measured the half time of blood disappearance rate of {sup 198}Au-colloid using external counting method in 94 normal persons and in 77 patients with various hepatic diseases. The results obtained were as follows: 1) In normal control, the mean blood disappearance half time of {sup 198}Au-colloid in supine position was 2.7+-0.4 minutes. There was no significant difference of hepatic blood flow in age and sex. 2) In acute hepatitis, chronic hepatitis and hepatic cirrhosis, the mean blood disappearance half times in supine position were 3.0+-0.45, 3.5+-0.74, 7.2+-3.6 minutes respectively. The hepatic blood flow of the patients with chronic hepatitis and hepatic cirrhosis were significantly decreased than that of normal control. 3) In the normal control and acute hepatitis, the decreases of the hepatic blood flow during the position change from supine to erect were 27.7% and 22.6% respectively.

    Full Text Available Tuberculosis (TB remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA, its circulating form DHEA-suphate (DHEA-s and cortisol in different stages of M. tuberculosis infection, and explored their role on the Th1 and Treg populations during different scenarios of HIV-TB coinfection, including the immune reconstitution inflammatory syndrome (IRIS, a condition related to antiretroviral treatment. DHEA levels were diminished in HIV-TB and HIV-TB IRIS patients compared to healthy donors (HD, HIV+ individuals and HIV+ individuals with latent TB (HIV-LTB, whereas dehydroepiandrosterone sulfate (DHEA-s levels were markedly diminished in HIV-TB IRIS individuals. HIV-TB and IRIS patients presented a cortisol/DHEA ratio significantly higher than HIV+, HIV-LTB and HD individuals. A positive correlation was observed between DHEA-s and CD4 count among HIV-TB individuals. Conversely, cortisol plasma level inversely correlated with CD4 count within HIV-TB individuals. M. tuberculosis-specific Th1 lymphocyte count was increased after culturing PBMC from HIV-TB individuals in presence of DHEA. We observed an inverse correlation between DHEA-s plasma level and Treg frequency in co-infected individuals, and CD4+FoxP3+ Treg frequency was increased in HIV-TB and IRIS patients compared to other groups. Strikingly, we observed a prominent CD4+CD25-FoxP3+ population across HIV-TB and HIV-TB IRIS patients, which frequency correlated with DHEA plasma level. Finally, DHEA treatment negatively regulated FoxP3 expression without altering Treg frequency in co-infected patients. These data suggest an enhancing role for DHEA in the immune response against M. tuberculosis during HIV-TB coinfection and IRIS.

    HIV prevalence and incidence in South Africa remain high, making HIV a part of everyday life. Community narratives on HIV treatment and prevention are important and influence official and unofficial health messaging and community perceptions and understandings of HIV. We explore how contributors and the columnist of an agony aunt column position HIV relative to choices made about love, partnership, and sex over three years. We analysed all columns of an agony aunt series (Antie Mona) published between December 2012 and November 2015. The column is published in a South African, Afrikaans-language newspaper "Son", prioritising sensationalist news items. Trends were identified through narrative analysis. Data were managed in ATLAS.ti and inductive, iterative coding conducted. It was found that letters to the agony aunt rarely refer to HIV directly (less than 7%). Euphemisms such as diseases of the flesh and the great flu were more commonly used instead of HIV or AIDS. Letters addressed HIV in three ways: direct references to experiences living with HIV; direct questions about HIV prevention; and scenarios where HIV could (from a public health perspective) have been the main concern, but everyday issues took precedence. The majority of letters fell into this latter category where the writers focused on the immediate concerns of good sexual relations, problems related to love and romantic relationships, good moral behaviour of others, and issues of oppressive life conditions rather than on HIV directly. The findings illustrate that informal, public contributions to health information, such as agony aunts, are important narratives that inform popular perspectives on HIV and health. A better appreciation of this context would allow health implementers to ensure that these role players receive updated health messaging to avoid the risk of HIV-related stigma where HIV is used as a moral rod to punish perceived moral transgressions.

    This study examined the moderating role of spiritual mindfulness on the association between spiritual coping and perceived growth in individuals with and without current treatment for cancer. Adults with a cancer history (N = 534) from the Midlife in the United States study completed a telephone interview and self-administered questionnaires. Moderated regression analyses, controlled for age and educational attainment, showed that mindfulness moderated the effect of spiritual coping on personal growth and on positive reinterpretation. High mindfulness amplified the effect of spiritual coping on both personal growth and positive reinterpretation. Further, this moderating effect was significantly different for adults with versus without current treatment for cancer for positive reinterpretation but not for personal growth. These findings highlight the potential amplifying effect of spiritual mindfulness on the effect of spiritual coping on perceived growth in cancer survivors.

  20. FWCW: a personal view.

    The personal experiences at the Beijing Fourth World Conference on Women and the Nongovernmental Organization (NGO) Forum were described by a Chinese American veterinarian. The author became aware that women were primarily the persons living in poverty in the world. Business and government appeared more concerned with economic growth. As a consequence, developed countries with 20% of world population consume 80% of the world's resources. The privilege of money secures a position of power in the world, power to buy up the resources of the world. This process is unsustainable and inequitable. Women are viewed as key players in shifting the balance in favor of a higher quality of life. The NGO workshops on Women in Livestock Development (WILD) was run by women veterinarians, who worked at the local level with women in poor areas. WILD operates out of offices in Arkansas in the USA. WILD women work in Sichuan, China, among the Han and Tibetans in increasing family income through heifer and livestock production. Conference participants from WILD programs talked about their experiences with increased income and loans to other women. The World Women's Veterinary Association members, who attended the conference, visited a small animal clinic in Beijing run by the Agriculture Ministry, and Beijing Agricultural University and its Veterinary Teaching Hospital. Demonstrations were given of small animal acupuncture. The author found the conference to be a success and found that press reports misrepresented the energy generated by the meeting.

    To estimate the budget impact of everolimus as the first and second treatment option after letrozole or anastrozole (L/A) failure for post-menopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor-2 negative (HER2-) advanced breast cancer (ABC). Pharmacy and medical budget impacts (2011 USD) were estimated over the first year of everolimus use in HR+, HER2- ABC from a US payer perspective. Epidemiology data were used to estimate target population size. Pre-everolimus entry treatment options included exemestane, fulvestrant, and tamoxifen. Pre- and post-everolimus entry market shares were estimated based on market research and assumptions. Drug costs were based on wholesale acquisition cost. Patients were assumed to be on treatment until progression or death. Annual medical costs were calculated as the average of pre- and post-progression medical costs weighted by the time in each period, adjusted for survival. One-way and two-way sensitivity analyses were conducted to assess the model robustness. In a hypothetical 1,000,000 member plan, 72 and 159 patients were expected to be candidates for everolimus treatment as first and second treatment option, respectively, after L/A failure. The total budget impact for the first year post-everolimus entry was $0.044 per member per month [PMPM] (pharmacy budget: $0.058 PMPM; medical budget: -$0.014 PMPM), assuming 10% of the target population would receive everolimus. The total budget impacts for the first and second treatment options after L/A failure were $0.014 PMPM (pharmacy budget: $0.018; medical budget: -$0.004) and $0.030 PMPM (pharmacy budget: $0.040; medical budget: -$0.010), respectively. Results remained robust in sensitivity analyses. Assumptions about some model input parameters were necessary and may impact results. Increased pharmacy costs for HR+, HER2- ABC following everolimus entry are expected to be partially offset by reduced medical service costs. Pharmacy and total

    Full Text Available Culture-negative bacteraemia has been an enigmatic entity with respect to its aetiological agents. In an attempt to actively identify those positive blood cultures that escape isolation and detection on routine workflow, an additional step of MALDI-TOF MS (matrix-assisted laser desorption ionization-time of flight mass spectrometry based detection was carried out directly from the flagged blood culture bottles. Blood samples from 200 blood culture bottles that beeped positive with automated (BACTEC system and showed no growth of organism on routine culture media, were subjected to analysis by MALDI-TOF MS. Forty seven of the 200 (23.5% bacterial aetiology could be established by bottle-based method. Based on these results, growth on culture medium could be achieved for the isolates by providing special growth conditions to the fastidious organisms. Direct identification by MALDI-TOF MS from BACTEC-positive bottles provided an opportunity to isolate those fastidious organisms that failed to grow on routine culture medium by providing them with necessary alterations in growth environment.

    This study examined trajectories of posttraumatic growth or depreciation (i.e., positive or negative life change) in personal strength and relationships after 2 major earthquakes in Canterbury, New Zealand using group-based trajectory modeling. Participants completed questionnaires regarding posttraumatic growth or depreciation in personal strength and relationship domains 1 month after the first earthquake in September 2010 (N = 185) and 3 months (n = 156) and 12 months (n = 144) after the more severe February 2011 earthquake. Three classes of growth or depreciation patterns were found for both domains. For personal strength, most of the participants were grouped into a "no growth or depreciation" class and smaller proportions were grouped into either a "posttraumatic depreciation" or "posttraumatic growth" class. The 3 classes for relationships all reported posttraumatic growth, differing only in degree. None of the slopes were significant for any of the classes, indicating that levels of growth or depreciation reported after the first earthquake remained stable when assessed at 2 time points after the second earthquake. Multinomial logistic regression analyses examining pre- and postearthquake predictors of trajectory class membership revealed that those in the "posttraumatic growth" personal strength class were significantly younger and had significantly higher pre-earthquake mental health than those in the "posttraumatic depreciation" class. Sex was the only predictor of the relationship classes: No men were assigned to the "high posttraumatic growth" class. Implications and future directions are discussed.

    Pleurotus ostreatus is a widely cultivated edible fungus in China. Green mold disease of P. ostreatus which can seriously affect yield is a common disease during cultivation. It occurs mostly after P. ostreatus mycelia have been subjected to high temperatures. However, little information is available on the relationship between high temperature and green mold disease. The aim of this study is to prove that extracellular metabolites of P. ostreatus affected by high temperature can promote the growth of Trichoderma asperellum . After P. ostreatus mycelia was subjected to high temperature, the extracellular fluid of P. ostreatus showed a higher promoting effect on mycelial growth and conidial germination of T. asperellum . The thiobarbituric acid reactive substance (TBARS) content reached the maximum after 48 h at 36°C. A comprehensive metabolite profiling strategy involving gas chromatography-mass spectrometry (GC/MS) combined with liquid chromatography-mass spectrometry (LC/MS) was used to analyze the changes of extracellular metabolites in response to high temperature. A total of 141 differential metabolites were identified, including 84.4% up-regulated and 15.6% down-regulated. Exogenous metabolites whose concentrations were increased after high temperature were randomly selected, and nearly all of them were able to promote the mycelial growth and conidial germination of T. asperellum . The combination of all selected exogenous metabolites also has the promotion effects on the mycelial growth and conidial germination of T. asperellum in a given concentration range in vitro . Overall, these results provide a first view that high temperature affects the extracellular metabolites of P. ostreatus , and the extensive change in metabolites promotes T. asperellum growth.

    Full Text Available The present research aimed to investigate the influence of personality (Five-Factor Model on Psychological Contract Breach. Using random sampling procedure, data were collected from 90 faculties of colleges of Royal University of Bhutan. Personality scales by John, Naumann, and Soto (2008 and Robinson and Morrison’s (2000 Psychological Contract Breach scale were used in this study. Correlation and regression analysis were carried out to analyze the obtained data. Results revealed that Extraversion and Neuroticism dimensions of the personality model have been found to be positively associated with the perception of breach. Employees who are by nature Agreeable and Conscientiousness are less likely to perceive breach in their psychological contract. Organization should look into the personality aspect while recruiting employees. If employees are hired with certain personality traits, they may focus on their performance and organizational growth.

    Full Text Available The Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D study has developed predictive risk scores for cardiovascular disease (CVD and chronic kidney disease (CKD, defined as confirmed estimated glomerular filtration rate [eGFR] ≤ 60 ml/min/1.73 m2 events in HIV-positive people. We hypothesized that participants in D:A:D at high (>5% predicted risk for both CVD and CKD would be at even greater risk for CVD and CKD events.We included all participants with complete risk factor (covariate data, baseline eGFR > 60 ml/min/1.73 m2, and a confirmed (>3 months apart eGFR 1%-5%, >5% and fitted Poisson models to assess whether CVD and CKD risk group effects were multiplicative. A total of 27,215 participants contributed 202,034 person-years of follow-up: 74% male, median (IQR age 42 (36, 49 years, median (IQR baseline year of follow-up 2005 (2004, 2008. D:A:D risk equations predicted 3,560 (13.1% participants at high CVD risk, 4,996 (18.4% participants at high CKD risk, and 1,585 (5.8% participants at both high CKD and high CVD risk. CVD and CKD event rates by predicted risk group were multiplicative. Participants at high CVD risk had a 5.63-fold (95% CI 4.47, 7.09, p < 0.001 increase in CKD events compared to those at low risk; participants at high CKD risk had a 1.31-fold (95% CI 1.09, 1.56, p = 0.005 increase in CVD events compared to those at low risk. Participants' CVD and CKD risk groups had multiplicative predictive effects, with no evidence of an interaction (p = 0.329 and p = 0.291 for CKD and CVD, respectively. The main study limitation is the difference in the ascertainment of the clinically defined CVD endpoints and the laboratory-defined CKD endpoints.We found that people at high predicted risk for both CVD and CKD have substantially greater risks for both CVD and CKD events compared with those at low predicted risk for both outcomes, and compared to those at high predicted risk for only CVD or CKD events. This suggests that CVD and

    Full Text Available The concept of positive mental health represents not merely the absence of mental disease but presence of high level of happiness and well-being. In this paper we mentioned shortly the earliest concept of mental health, presented by Marie Jahoda in the mid-twentieth century. After that, we described two traditions in understanding and researching of subjective well-being: hedonic and eudaimonic approach. First approach focuses on investigation of positive affects and happiness as emotional and life satisfaction as cognitive component of subjective well-being. Second tradition emphasizes potentials and competences that person develops to the highest level, in personal and social area. Both psychological and social well-being are core concept of positive mental health psychology, designated together as positive functioning. The psychological well-being comprises six dimensions: self-acceptance, positive relations with others, environmental mastery, autonomy, purpose of life and personal growth. Social well-being consists of five dimensions: social integration, social acceptance, social contribution, social actualization and social coherence. By integrating hedonic and eudaimonic well-being as well as absence of mental disease, Corey Keyes introduced concept of complete mental health. People with complete mental health have reported absence of disease during past year and presence of high level of emotional, psychological and social well-being (flourishing. People with incomplete mental health have also reported absence of mental disease but low level of positive functioning (languishing. Keyes thought there are people with complete and incomplete mental illness; both groups report presence of mental disease, but second group has high level of positive functioning. Models of positive mental health are widely used in research studies as well as in programs for prevention and promotion of mental health. .

    Urodele amphibians are unique among adult vertebrates in their ability to regenerate complex body structures after traumatic injury. In salamander regeneration, the cells maintain a memory of their original position and use this positional information to recreate the missing pattern. We used an in vivo gain-of-function assay to determine whether components of the extracellular matrix (ECM) have positional information required to induce formation of new limb pattern during regeneration. We discovered that salamander limb ECM has a position-specific ability to either inhibit regeneration or induce de novo limb structure, and that this difference is dependent on heparan sulfates that are associated with differential expression of heparan sulfate sulfotransferases. We also discovered that an artificial ECM containing only heparan sulfate was sufficient to induce de novo limb pattern in salamander limb regeneration. Finally, ECM from mouse limbs is capable of inducing limb pattern in axolotl blastemas in a position-specific, developmental-stage-specific, and heparan sulfate-dependent manner. This study demonstrates a mechanism for positional information in regeneration and establishes a crucial functional link between salamander regeneration and mammals.

    2015-11-01

    Full Text Available Growth hormone-releasing hormone (GHRH and the receptor, GHRHR, constitute important components of the hypothalamus-pituitary growth axis and act on the downstream growth hormone (GH. PACAP-related peptide/pituitary adenylate cyclase activating polypeptide (PRP-PACAP is a paralog of GHRH. These genes all play key roles in development and growth patterns. To improve the quality of cultured fish strains, natural genetic variation must be examined and understood. A mixed linear model has been widely used in association mapping, taking the population structures and pairwise kinship patterns into consideration. In this study, a mass cross population of orange-spotted grouper (Epinephelus coioides was examined. These candidate genes were found to harbor low nucleotide diversity (θw from 0.00154 to 0.00388 and linkage disequilibrium levels (delay of 50% within 2 kbp. Association mapping was employed, and two single-nucleotide polymorphisms (KR269823.1:g.475A>C and KR269823.1:g.2143T>C were found to be associated with growth (false discovery rate Q < 0.05, explaining 9.0%–17.0% of the phenotypic variance. The association of KR269823.1:g.2143T>C was also found via haplotype-based association (p < 0.05. The identified associations offer new insights into gene functions, and the associated single-nucleotide polymorphisms (SNPs may be used for breeding purposes.

  15. Are Applied Growth Factors Able to Mimic the Positive Effects of Mesenchymal Stem Cells on the Regeneration of Meniscus in the Avascular Zone?

    Directory of Open Access Journals (Sweden)

    Johannes Zellner

    2014-01-01

    Full Text Available Meniscal lesions in the avascular zone are still a problem in traumatology. Tissue Engineering approaches with mesenchymal stem cells (MSCs showed successful regeneration of meniscal defects in the avascular zone. However, in daily clinical practice, a single stage regenerative treatment would be preferable for meniscus injuries. In particular, clinically applicable bioactive substances or isolated growth factors like platelet-rich plasma (PRP or bone morphogenic protein 7 (BMP7 are in the focus of interest. In this study, the effects of PRP and BMP7 on the regeneration of avascular meniscal defects were evaluated. In vitro analysis showed that PRP secretes multiple growth factors over a period of 8 days. BMP7 enhances the collagen II deposition in an aggregate culture model of MSCs. However applied to meniscal defects PRP or BMP7 in combination with a hyaluronan collagen composite matrix failed to significantly improve meniscus healing in the avascular zone in a rabbit model after 3 months. Further information of the repair mechanism at the defect site is needed to develop special release systems or carriers for the appropriate application of growth factors to support biological augmentation of meniscus regeneration.

    Fibroblast-like stromal cells modulate cancer cells through secreted factors and adhesion, but those factors are not fully understood. Here, we have identified critical stromal factors that modulate cancer growth positively and negatively. Using a cell co-culture system, we found that gastric stromal cells secreted IL-6 as a growth and survival factor for gastric cancer cells. Moreover, gastric cancer cells secreted PGE2 and TNFα that stimulated IL-6 secretion by the stromal cells. Furthermore, we found that stromal cells secreted glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Extracellular GAPDH, or its N-terminal domain, inhibited gastric cancer cell growth, a finding confirmed in other cell systems. GAPDH bound to E-cadherin and downregulated the mTOR-p70S6 kinase pathway. These results demonstrate that stromal cells could regulate cancer cell growth through the balance of these secreted factors. We propose that negative regulation of cancer growth using GAPDH could be a new anti-cancer strategy. PMID:25785838

    This study evaluated a multiplex real-time PCR method specific for the mecA, femA-SA and femA-SE genes for rapid identification of Staphylococcus aureus, Staphylococcus epidermidis and non-S. epidermidis coagulase-negative staphylococci (CoNS), and meticillin susceptibility testing directly in positive blood cultures that grew Gram-positive cocci in clusters. A total of 100 positive blood cultures produced: 39 S. aureus [12 meticillin-resistant S. aureus (MRSA), 31% of all the S. aureus]; 30 S. epidermidis (56.6% of the CoNS), 8 Staphylococcus capitis (15.1%), 3 Staphylococcus saprophyticus (5.7%), 4 Staphylococcus hominis (7.5%), 3 Staphylococcus haemolyticus (5.7%), 2 Staphylococcus warneri (3.8%), 1 Staphylococcus cohnii (1.9%) and 2 unidentified Staphylococcus spp. (3.8%); and 1 Micrococcus luteus in pure culture. Two blood cultures had no growth on subculture and five blood cultures grew mixed CoNS. For the 95 blood cultures with pure growth or no growth on subculture, there was very good agreement between real-time PCR and the BD Phoenix identification system for staphylococcal species categorization in S. aureus, S. epidermidis and non-S. epidermidis CoNS and meticillin-resistance determination (Cohen's unweighted kappa coefficient κ=0.882). All MRSA and meticillin-susceptible S. aureus were correctly identified by mecA amplification. PCR amplification of mecA was more sensitive for direct detection of meticillin-resistant CoNS in positive blood cultures than testing with the BD Phoenix system. There were no major errors when identifying staphylococcal isolates and their meticillin susceptibility within 2.5 h. Further studies are needed to evaluate the clinical benefit of using such a rapid test on the consumption of glycopeptide antibiotics and the alteration of empiric therapy in the situation of positive blood cultures growing staphylococci, and the respective clinical outcomes.

    Purpose: Approximately 40% of all glioblastomas have amplified the EGFR gene, and about half of these tumors express the EGFRvIII variant. The prognostic role of EGFRvIII in EGFR -amplified glioblastoma patients and changes in EGFRvIII expression in recurrent versus primary glioblastomas remain controversial, but such data are highly relevant for EGFRvIII-targeted therapies. Experimental Design: EGFR -amplified glioblastomas from 106 patients were assessed for EGFRvIII positivity. Changes in EGFR amplification and EGFRvIII status from primary to recurrent glioblastomas were evaluated in 40 patients with EGFR -amplified tumors and 33 patients with EGFR -nonamplified tumors. EGFR single-nucleotide variants (SNV) were assessed in 27 patients. Data were correlated with outcome and validated in 150 glioblastoma patients from The Cancer Genome Atlas (TCGA) consortium. Results: Sixty of 106 EGFR -amplified glioblastomas were EGFRvIII-positive (56.6%). EGFRvIII positivity was not associated with different progression-free or overall survival. EGFRvIII status was unchanged at recurrence in 35 of 40 patients with EGFR -amplified primary tumors (87.5%). Four patients lost and one patient gained EGFRvIII positivity at recurrence. None of 33 EGFR- nonamplified glioblastomas acquired EGFR amplification or EGFRvIII at recurrence. EGFR SNVs were frequent in EGFR -amplified tumors, but were not linked to survival. Conclusions: EGFRvIII and EGFR SNVs are not prognostic in EGFR -amplified glioblastoma patients. EGFR amplification is retained in recurrent glioblastomas. Most EGFRvIII-positive glioblastomas maintain EGFRvIII positivity at recurrence. However, EGFRvIII expression may change in a subset of patients at recurrence, thus repeated biopsy with reassessment of EGFRvIII status is recommended for patients with recurrent glioblastoma to receive EGFRvIII-targeting agents.

    Drawing on prior occupational choice research on entrepreneurs and self-employed business owners, we examined personality predictors of their occupational business success and work satisfaction. PARTICIPANTS AND PROCEDURES: A sample of 147 small business owners completed a web-based assessment of 14 work-related personality traits--adaptability, autonomy, competitiveness, dependability, emotional resilience, goal-setting, optimism, persistence, risk tolerance, self-promotion, networking, and tolerance for financial insecurity, work-based locus of control, and work drive--and three self-reported indices of business success--revenue growth, profit growth, and income growth--as well as multiple facets of individual satisfaction. Criterion variables included composite business success and overall satisfaction. Ten traits correlated with business success. The top four personality predictors of success--goal-setting, social networking, emotional resilience, and work drive--together accounted for 16% of the variance. Similarly, 12 of 14 personality traits were positively related to overall satisfaction. The top three personality predictors of satisfaction--optimism, work-based locus of control, and work drive--accounted for 29% of the variability in satisfaction. An expectancy analysis revealed that the percent of participants who reported at least a 20% increase in sales and profits the preceding year was 26% versus 54% for individual scoring in the lower and upper third of a personality composite measure. Results carry implications for future research, and have direct, practical applications for prospective and current entrepreneurs and self-employed owners of small businesses.

  4. Personal disclosure revisited.

    Science.gov (United States)

    Olarte, Silvia W

    2003-01-01

    In this paper personal disclosure is defined as a conscious verbal presentation to the patient by the therapist of a personal vignette accompanied by the appropriate dynamic formulation and resolution of a given personal area of conflict. It is conceptualized within theoretical formulations which consider the therapeutic relationship a dyad, where the reality of the patient and the reality of the therapist influence each other, providing the matrix through which the resolution of the patient's past life experiences takes place in the context of this new interpersonal experience. It is specifically differentiated from a boundary violation, because the personal disclosure is brought to the patient's interactional awareness not for gratification of the therapist's sexual or narcissistic needs, but to provoke a response in the patient's conceptualization of a phenomenon being presented in the session and to actively influence the intersubjective field. Within the conceptual framework developed in this paper, personal disclosure reaffirms the patient's current self-discovery and provides for a different formative experience. Personal disclosure is not to be used by the therapist as a vehicle to resolve personal conflicts or as source of personal gratification. When used within the context developed in this paper, personal disclosure enhances both the patient's therapeutic process and the therapist's ever-evolving growth.

  5. Perspectives on population growth.

    Science.gov (United States)

    1996-09-01

    Assume that everyone has the same information on population growth. There are many different opinions on what that information means and what should be done about it. Some people worry about current rates of growth, especially in the context of growing per capita consumption, and believe that all reasonable steps should be taken to reduce rates and stabilize population size. Others believe that growing populations can be accommodated by reducing consumption in rich countries, that technological progress will supply the new resources needed, that the development needed to support a larger population can be sustained, that large population size fosters prosperity, or that birth rates are falling and current growth is just temporary. These are all valid positions worthy of at least debate. Interest groups commonly acknowledgement population growth as a significant issue, but offer no response to it. Sometimes the issue goes unrecognized because it conflicts with a more highly valued personal agenda item. Finally, some responses come from confusion and anger rather than reasoning or self-interest. The proponents of these latter arguments bring nothing constructive to the debate.

    Purpose The approval history, pharmacology, pharmacokinetics, clinical trials, efficacy, dosing recommendations, drug interactions, safety, place in therapy, and economic considerations of gefitinib are reviewed. Summary Lung cancer is one of the most commonly diagnosed cancers and is the leading cause of cancer death. Platinum-based chemotherapy and tyrosine kinase inhibitors, such as erlotinib and afatinib, are recommended therapies for nonsmall cell lung cancer. The European Medicines Association based their approval of gefitinib on the randomized, multicenter Iressa Pan-Asia Study (IPASS, NCT00322452) and a single-arm study showing effectiveness in Caucasians (IFUM, NCT01203917). Both studies were recently referenced by the United States Food & Drug Administration to reapprove gefitinib for the first-line treatment of advanced nonsmall cell lung cancer with epidermal growth factor receptor exon 19 deletions or exon 21 substitution. Diarrhea, acneiform rash, and interstitial lung disease are known side effects of gefitinib. Conclusion Use of gefitinib for the first-line therapy of metastatic nonsmall cell lung cancer with epidermal growth factor receptor exon 19 deletions (residues 747-750) or exon 21 substitution mutation (L858R) is well-documented and supported.

    2014-03-01

    The primary aim of this paper was to evaluate the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and its relationship with proangiogenic factors and microvessel density (MVD) in ovarian cancer. The study group included 58 epithelial ovarian cancers (EOCs), 35 benign ovarian tumors, and 21 normal ovaries. The expression of EMMPRIN, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) was assessed by ELISA of tissue homogenates. Antibodies against CD105, CD31, and CD34 were used to immunohistochemically assess MVD. We have found significantly higher EMMPRIN expression in EOC than in benign ovarian tumors and normal ovaries. Similarly, the VEGF expression was higher in EOC than in benign ovarian tumors and normal ovaries. By contrast, bFGF expression was lower in EOC than in benign ovarian tumors and ovary samples. EMMPRIN expression in EOC was directly correlated with VEGF expression and CD105-MVD, but inversely correlated with bFGF expression. Grade 2/3 ovarian cancers had increased expression of EMMPRIN and VEGF, increased CD105-MVD, and lowered expression of bFGF compared to grade 1 ovarian cancers. Moreover, EMMPRIN expression was higher in advanced (FIGO III and IV) ovarian cancer. The upregulation of EMMPRIN and VEGF expression is correlated with increased CD105-MVD and silenced bFGF, which suggests early and/or reactivated angiogenesis in ovarian cancer. Aggressive EOC is characterized by the following: high expression of EMMPRIN and VEGF, high CD105-MVD, and low expression of bFGF.

    There are widespread concerns about abuse of care home residents. We report, in the largest care home survey, prevalence of staff anonymously-reported, perpetrated/witnessed abusive behaviours towards care home residents over 3 months. We also report positive care behaviours. 1544 staff in 92 English care home units completed the revised Modified Conflict Tactics Scale and Maslach Burnout Inventory. Most staff reported positive care behaviours, but specific person-centred activities were sometimes infrequent. Many care home staff were never or almost never aware of a resident being taken out of the home for their enjoyment (34%, n = 520); or an activity planned around a resident's interests (15%, n = 234). 763 (51%; 95% Confidence Interval (CI) 47% to 54%) of care home staff reported carrying out or observing potentially abusive or neglectful behaviours at least sometimes in the preceding 3 months; some abuse was reported as happening "at least sometimes" in 91/92 care homes. Neglect was most frequently reported: making a resident wait for care (n = 399, 26%), avoiding a resident with challenging behaviour (n = 391, 25%), giving residents insufficient time for food (n = 297, 19%), and taking insufficient care when moving residents (n = 169, 11%). 1.1% of staff reported physical and 5% verbal abuse. More staff reported abusive/neglectful behaviour in homes with higher staff burnout-depersonalisation scores (adjusted odds ratio 1.191, CI 1.052-1.349). Staff anonymous reports of abusive behaviour and neglect could be used to monitor care quality, as cases currently reported are probably tip of the iceberg, and be an outcome in intervention studies.

    2009-03-01

    The present research investigated the longitudinal relations between personality traits and narratives. Specifically, the authors examined how individual differences in 170 college students' narratives of personality change (a) were predicted by personality traits at the beginning of college, (b) related to actual changes and perceived changes in personality traits during college, and (c) related to changes in emotional health during college. Individual differences in narratives of personality trait change told in the 4th year of college fell into 2 dimensions: affective processing, characterized by positive emotions, and exploratory processing, characterized by meaning making and causal processing. Conscientious, open, and extraverted freshmen told exploratory stories of change as seniors. Emotionally healthy freshmen told stories of change that were high in positive affect. Both positive affective and exploratory stories corresponded to change in emotional stability and conscientiousness during college above and beyond the effects of perceived changes in these traits. In addition, both positive affective and exploratory narratives corresponded to increases in emotional health during college independent of the effects of changes in personality traits. These findings improve our understanding of how individuals conceptualize their changing identity over time.

    The HER3 receptor is implicated in the progression of various cancers as well as in resistance to several currently used drugs, and is hence a potential target for development of new therapies. We have previously generated Affibody molecules that inhibit heregulin-induced signaling of the HER3 pathways. The aim of this study was to improve the affinity of the binders to hopefully increase receptor inhibition efficacy and enable a high receptor-mediated uptake in tumors. We explored a novel strategy for affinity maturation of Affibody molecules that is based on alanine scanning followed by design of library diversification to mimic the result from an error-prone PCR reaction, but with full control over mutated positions and thus less biases. Using bacterial surface display and flow-cytometric sorting of the maturation library, the affinity for HER3 was improved more than 30-fold down to 21 pM. The affinity is among the higher that has been reported for Affibody molecules and we believe that the maturation strategy should be generally applicable for improvement of affinity proteins. The new binders also demonstrated an improved thermal stability as well as complete refolding after denaturation. Moreover, inhibition of ligand-induced proliferation of HER3-positive breast cancer cells was improved more than two orders of magnitude compared to the previously best-performing clone. Radiolabeled Affibody molecules showed specific targeting of a number of HER3-positive cell lines in vitro as well as targeting of HER3 in in vivo mouse models and represent promising candidates for future development of targeted therapies and diagnostics.

    Connective tissue growth factor (CTGF) is involved in human cancer development and progression. Epithelial to mesenchymal transition (EMT) plays an important role in many biological processes. In this study, we wished to investigate the role of CTGF in EMT of peritoneal mesothelial cells and the effects of CTGF on adhesion of gastric cancer cells to mesothelial cells. Human peritoneal mesothelial cells (HPMCs) were cultured with TGF-β1 or various concentrations of CTGF for different time. The EMT process was monitored by morphology. Real-time RT-PCR and Western blot were used to evaluate the expression of vimentin, α-SMA , E-cadherin and β-catenin. RNA interference was used to achieve selective and specific knockdown of CTGF. We demonstrated that CTGF induced EMT of mesothelial cells in a dose- and time-dependent manner. HPMCs were exposed to TGF-β1 also underwent EMT which was associated with the induction of CTGF expression. Transfection with CTGF siRNA was able to reverse the EMT partially after treatment of TGF-β1. Moreover, the induced EMT of HPMCs was associated with an increased adhesion of gastric cancer cells to mesothelial cells. These findings suggest that CTGF is not only an important mediator but a potent activator of EMT in peritoneal mesothelial cells, which in turn promotes gastric cancer cell adhesion to peritoneum.

  17. Promoter of CaZF, a chickpea gene that positively regulates growth and stress tolerance, is activated by an AP2-family transcription factor CAP2.

    Directory of Open Access Journals (Sweden)

    Deepti Jain

    Full Text Available Plants respond to different forms of stresses by inducing transcription of a common and distinct set of genes by concerted actions of a cascade of transcription regulators. We previously reported that a gene, CaZF encoding a C2H2-zinc finger family protein from chickpea (Cicer arietinum imparted high salinity tolerance when expressed in tobacco plants. We report here that in addition to promoting tolerance against dehydration, salinity and high temperature, the CaZF overexpressing plants exhibited similar phenotype of growth and development like the plants overexpressing CAP2, encoding an AP2-family transcription factor from chickpea. To investigate any relationship between these two genes, we performed gene expression analysis in the overexpressing plants, promoter-reporter analysis and chromatin immunoprecipitation. A number of transcripts that exhibited enhanced accumulation upon expression of CAP2 or CaZF in tobacco plants were found common. Transient expression of CAP2 in chickpea leaves resulted in increased accumulation of CaZF transcript. Gel mobility shift and transient promoter-reporter assays suggested that CAP2 activates CaZF promoter by interacting with C-repeat elements (CRTs in CaZF promoter. Chromatin immunoprecipitation (ChIP assay demonstrated an in vivo interaction of CAP2 protein with CaZF promoter.

    After massive tears, rotator cuff muscle often undergoes atrophy, fibrosis, and fatty degeneration. These changes can lead to high surgical failure rates and poor patient outcomes. The identity of the progenitor cells involved in these processes has not been fully elucidated. Platelet-derived growth factor receptor β (PDGFRβ) and platelet-derived growth factor receptor α (PDGFRα) have previously been recognized as markers of cells involved in muscle fibroadipogenesis. We hypothesized that PDGFRα expression identifies a fibroadipogenic subset of PDGFRβ + progenitor cells that contribute to fibroadipogenesis of the rotator cuff. We created massive rotator cuff tears in a transgenic strain of mice that allows PDGFRβ + cells to be tracked via green fluorescent protein (GFP) fluorescence. We then harvested rotator cuff muscle tissues at multiple time points postoperatively and analyzed them for the presence and localization of GFP + PDGFRβ + PDGFRα + cells. We cultured, induced, and treated these cells with the molecular inhibitor CWHM-12 to assess fibrosis inhibition. GFP + PDGFRβ + PDGFRα + cells were present in rotator cuff muscle tissue and, after massive tears, localized to fibrotic and adipogenic tissues. The frequency of PDGFRβ + PDGFRα + cells increased at 5 days after massive cuff tears and decreased to basal levels within 2 weeks. PDGFRβ + PDGFRα + cells were highly adipogenic and significantly more fibrogenic than PDGFRβ + PDGFRα - cells in vitro and localized to adipogenic and fibrotic tissues in vivo. Treatment with CWHM-12 significantly decreased fibrogenesis from PDGFRβ + PDGFRα + cells. PDGFRβ + PDGFRα + cells directly contribute to fibrosis and fatty degeneration after massive rotator cuff tears in the mouse model. In addition, CWHM-12 treatment inhibits fibrogenesis from PDGFRβ + PDGFRα + cells in vitro. Clinically, perioperative PDGFRβ + PDGFRα + cell inhibition may limit rotator cuff tissue degeneration and, ultimately

  1. Cerebellum and personality traits.

    Personality traits are multidimensional traits comprising cognitive, emotional, and behavioral characteristics, and a wide array of cerebral structures mediate individual variability. Differences in personality traits covary with brain morphometry in specific brain regions. A cerebellar role in emotional and affective processing and on personality characteristics has been suggested. In a large sample of healthy subjects of both sexes and differently aged, the macro- and micro-structural variations of the cerebellum were correlated with the scores obtained in the Temperament and Character Inventory (TCI) by Cloninger. Cerebellar volumes were associated positively with Novelty Seeking scores and negatively with Harm Avoidance scores. Given the cerebellar contribution in personality traits and emotional processing, we investigated the cerebellar involvement even in alexithymia, construct of personality characterized by impairment in cognitive, emotional, and affective processing. Interestingly, the subjects with high alexithymic traits had larger volumes in the bilateral Crus 1. The cerebellar substrate for some personality dimensions extends the relationship between personality and brain areas to a structure up to now thought to be involved mainly in motor and cognitive functions, much less in emotional processes and even less in personality individual differences. The enlarged volumes of Crus 1 in novelty seekers and alexithymics support the tendency to action featuring both personality constructs. In fact, Novelty Seeking and alexithymia are rooted in behavior and inescapably have a strong action component, resulting in stronger responses in the structures more focused on action and embodiment, as the cerebellum is.

  2. Self-regard in the structure of personality behavioural manifestations

    2012-12-01

    Full Text Available The article focuses on the issue of self-regard connected with behavioural manifestations of personality. By means of comparative, correlation and factorial analysis it is proven that positive self-regard is accompanied by a decreasing level of suicidal risk as well as by creativity growth. Self-acceptance, positive attitude towards oneself ensures a harmonious existence and a high level of personality self-identifi cation. Higher level of self-regard is revealed in younger age categories where it is based on optimistic life prospects and a creative approach to solving life problems. Creativity combined with self-liking becomes a certain ability that helps overcome crisis situations and facilitates removal of personal peculiarities connected with proneness to suicide. Among the creative skills and abilities foregrounded are creative approach, creative imagination and creative intuition

  3. Disruption of Smad-dependent signaling for growth of GST-P-positive lesions from the early stage in a rat two-stage hepatocarcinogenesis model

    To clarify the involvement of signaling of transforming growth factor (TGF)-β during the hepatocarcinogenesis, the immunohistochemical distribution of related molecules was analyzed in relation with liver cell lesions expressing glutathione S-transferase placental form (GST-P) during liver tumor promotion by fenbendazole, phenobarbital, piperonyl butoxide, or thioacetamide, using rats. Our study focused on early-stage promotion (6 weeks after starting promotion) and late-stage promotion (57 weeks after starting promotion). With regard to Smad-dependent signaling, cytoplasmic accumulation of phosphorylated Smad (phospho-Smad)-2/3 - identified as Smad3 by later immunoblot analysis - increased in the subpopulation of GST-P + foci, while Smad4, a nuclear transporter of Smad2/3, decreased during early-stage promotion. By late-stage promotion, GST-P + lesions lacking phospho-Smad2/3 had increased in accordance with lesion development from foci to carcinomas, while Smad4 largely disappeared in most proliferative lesions. With regard to Smad-independent mitogen-activated protein kinases, GST-P + foci that co-expressed phospho-p38 mitogen-activated protein kinase increased during early-stage promotion; however, p38-downstream phospho-activating transcriptional factor (ATF)-2, ATF3, and phospho-c-Myc, were inversely downregulated without relation to promotion. By late-stage promotion, proliferative lesions downregulated phospho-ATF2 and phospho-c-Myc along with lesion development, as with downregulation of phospho-p38 in all lesions. These results suggest that from the early stages, carcinogenic processes were facilitated by disruption of tumor suppressor functions of Smad-dependent signaling, while Smad-independent activation of p38 was an early-stage phenomenon. GST-P - foci induced by promotion with agonists of peroxisome proliferator-activated receptor-α did not change Smad expression, suggesting an aberration in the Smad-dependent signaling prerequisites for induction

    College student excessive alcohol use is a pressing public health concern, and many of the negative events associated with heavy drinking occur during leisure or free time. Positive use of leisure can lead to coping skills, stress reduction, and healthy development. Negative use of leisure, including heavy alcohol use, is associated with physical inactivity, stress, and short and long-term health concerns. We contend that using the classroom context to help college students understand why it is beneficial to engage in positive leisure pursuits and how that engagement will promote personal growth is of critical importance to healthy development.

    Information and communication technologies are widely and rapidly spreading in people's daily lives. But what is the possible role of the mass proliferation of digital devices in supporting healthy living and active ageing? Are they useful in fostering personal growth and individual integration of the elderly, by promoting satisfaction, opportunities for action, and self-expression? Rather, do they enhance automation, impose constraints on personal initiative, and result in compulsive consumption of information? In this chapter, we suggest that possible answers to these questions will be offered by the "Positive Technology" approach, i.e., the scientific and applied approach to using technology so that it improves the quality of our personal experiences through its structuring, augmentation, and/or replacement. First, we suggest that it is possible to use technology to manipulate the quality of experience with the goal of increasing wellness and generating strengths and resilience in individuals, organizations, and society. Then, we classify positive technologies according to their effects on these three features of personal experience - Hedonic: technologies used to induce positive and pleasant experiences; Eudaimonic: technologies used to support individuals in reaching engaging and self-actualizing experiences; Social/Interpersonal: technologies used to support and improve the connectedness between individuals, groups, and organizations. Finally, we discuss the possible role of positive technologies for healthy living and active ageing by presenting different practical applications of this approach.

    Positive psychology is a deliberate correction to the focus of psychology on problems. Positive psychology does not deny the difficulties that people may experience but does suggest that sole attention to disorder leads to an incomplete view of the human condition. Positive psychologists concern themselves with four major topics: (1) positive…

    Full Text Available A series of studies investigated a proposed new individual difference characteristic or trait, facility for sustained positive affect, consisting of tendencies that allow individuals to maintain a high level of positive mood. Exploratory and confirmatory factor analyses resulted in the creation of a measure, the self-congruent and new activities (SANA scale which identified two core aspects of sustainable positive affect, engaging in self-congruent activities and engaging in new activities. A higher level of facility for sustainable affect, as operationalized by the SANA scale, was associated with maintenance of positive mood for a month, fewer symptoms of depression and anxiety, less negative affect, and more life satisfaction, relationship satisfaction, work satisfaction, mindfulness, personal expansion and growth, and emotional intelligence. The results provided initial evidence that facility to maintain positive affect may be an emotion-related individual difference characteristic.

    positionings emerges based on empirical examples of research in parent–children consumption. Positionings are flexible discursive fixations of the relationship between the performances of the practitioner, other practitioners, media discourse and consumption activities. The basic positioning types...... are the practice maintenance and the practice change position, with different sorts of adapting in between. Media discourse can become a resource for a resistant position against social control or for an appropriating position in favour of space for action. Regardless of the current relation to a particular media......This article analyses the ways in which media discourses become a part of contested consumption activities. We apply a positioning perspective with practice theory to focus on how practitioners relate to media discourse as a symbolic resource in their everyday practices. A typology of performance...

    Breast cancers that overexpress the human epidermal growth factor receptor 2 (HER2) are eligible for effective biologically targeted therapies, such as trastuzumab. However, accurately determining HER2 overexpression, especially in immunohistochemically equivocal cases, remains a challenge. Manual analysis of HER2 expression is dependent on the assessment of membrane staining as well as comparisons with positive controls. In spite of the strides that have been made to standardize the assessment process, intra- and inter-observer discrepancies in scoring is not uncommon. In this manuscript we describe a pathologist assisted, computer-based continuous scoring approach for increasing the precision and reproducibility of assessing imaged breast tissue specimens. Computer-assisted analysis on HER2 IHC is compared with manual scoring and fluorescence in situ hybridization results on a test set of 99 digitally imaged breast cancer cases enriched with equivocally scored (2+) cases. Image features are generated based on the staining profile of the positive control tissue and pixels delineated by a newly developed Membrane Isolation Algorithm. Evaluation of results was performed using Receiver Operator Characteristic (ROC) analysis. A computer-aided diagnostic approach has been developed using a membrane isolation algorithm and quantitative use of positive immunostaining controls. By incorporating internal positive controls into feature analysis a greater Area Under the Curve (AUC) in ROC analysis was achieved than feature analysis without positive controls. Evaluation of HER2 immunostaining that utilized membrane pixels, controls, and percent area stained showed significantly greater AUC than manual scoring, and significantly less false positive rate when used to evaluate immunohistochemically equivocal cases. It has been shown that by incorporating both a membrane isolation algorithm and analysis of known positive controls a computer-assisted diagnostic algorithm was

    The authors collected nationally representative data on Canadian residents' experiences with and perspectives on personal psychotherapy in their psychiatric training. A 43-item questionnaire was distributed electronically to all current psychiatry residents in Canada (N = 839). Four hundred residents from every program across Canada returned the survey (response rate 47.7%). The prevalence of personal therapy at any time was 55.3%, with 42.8% receiving personal therapy during residency. Of residents who undertook personal psychotherapy, 59.3% engaged in weekly therapy, 74.1% received psychodynamic psychotherapy, and 81.5% participated in long-term therapy (>1 year). Personal growth, self-understanding, and professional development were the most common reasons for engaging in personal therapy; however, one-third of residents did so to alleviate symptoms of depression, anxiety, or other mental health concerns. Time was the most important factor impeding residents from personal therapy; only 8.8% found stigma to act as a barrier. The vast majority of residents rated their experience with personal therapy as having a positive or very positive impact on their personal life (84.8%) and overall development as psychiatrists (81.8%). For 64% of respondents, personal therapy had an important or very important role in psychiatry residency training. Residents who received personal therapy rated themselves as better able to understand what happens moment by moment during therapy sessions, detect and deal with patients' emotional reactions, and constructively use their personal reactions to patients. Interest in personal therapy remains strong among psychiatry trainees in Canada. Residents who engaged in psychotherapy endorsed greater confidence in psychotherapy and rated their psychotherapy skills more favorably than those who had never been in the patient role, supporting the view of personal therapy as an important adjunct to psychotherapy training during residency.
