TMJ AND POSTURAL DISORDERS: IMPROVEMENT AFTER USE OF A MICROCHIP
No full textAim. Many patients with TMJ problems have made numerous visits from one physician to another; some
have even been hospitalized by a neurologist and many patients never get correctly diagnosed. Several
studies have identified impairments in postural control in patients with temporomandibular disorders.
There are several methods to alleviate TMD, and some studies have suggested that it is possible to control
the stomatognathic system and the musculoskeletal system through the “foot support”. The aim of the
present study was to evaluate the variation produced by microchip in foot plantar in temporomandibular
and postural disorders
Stress and depression predict relationship satisfaction with gender differences
No full textIntroduction: Factors associated with marital satisfaction are multiple. Psychological health of both partners have been showed to play a fundamental role. Empirical evidences showed negative association between stress and relationship satisfaction, thus highlighting the need of examining stress as a dyadic phenomenon. Similarly, depression seems to negatively predict marital satisfaction, varying across gender. However, evidences are still lacking.
Method: This study aims to explore psychological factors associated with relationship satisfaction of both partners in heterosexual Italian couples. Measures of stress, depression, reported received support from the other partner, relationship satisfaction and sociodemographic information were collected from both partner. Two hierarchical multiple regression analyses were conducted separately for gender, considering relationship satisfaction as dependent variable. As independent variables were included: duration of the relationship, personal depression, reported received support from the other partner, partner’s stress and depression. Results:122 couples participated in the study (female Mage=26.09±7.25, male Mage=33.08±11.23, 60% engaged, 30% married and 10% cohabiting partners). The mean duration of the relationship was 8.5 ± 10.0 years. Gender differences were significant among stress (t= 3,28, p= 0,001) and reported received support from the other partner (t=-2,10, p=0,038): females reported higher level of stress and less reported received support from the other partner, compared to males. Regression analyses showed that factors predicting relationship satisfaction for men were: relationship duration, their own depression (ps<.001) and female partner’s stress (p=.013, R2=0.29, R2 Change=0.083, p=0.002). For female partners, factors predicting relationship satisfaction were only stress (p=.056) and depression (p<.001) of their male partners (R2=0.20, R2 Change=0.132, p< 0.001). Conclusions: Results indicated that relationship satisfaction may vary according to gender. In fact, relationship duration and males depressive symptoms predicted greater relationship satisfaction, while female partner's stress negatively affected it. Males depressive symptoms predicted greater relationship satisfaction in the female partner, while the male stress negatively impacted it
To be or not to be in a couple: perfectionism as a predictor
No full textThe creation and maintenance of a stable and long-lasting relationship are crucial for adult individual well-being, with single people reporting poorer mental health when compared to those engaged in romantic relationships. Among the factors that may predict the quality of romantic dyads, scholars have addressed dyadic perfectionism. However, few is known about which of the perfectionism dimensions better predicts the status of being single or engaged in a romantic relationship. The present study aims to verify whether perfectionism is associated with the relationship status, and which perfectionism dimension is involved. More specifically, the interpersonal aspects of dyadic perfectionism were expected to be positively associated with the probability of belonging to the “single status”. Contributions of demographic variables as well as effects of mental health symptoms were controlled as they are relevant factors influencing romantic relationships. A hierarchical logistic regression analysis was conducted to evaluate the predictive utility of age and gender (controlled for at Step 1), depression and anxiety (entered at Step 2) and intra-and interpersonal perfectionism dimensions (controlled at Step 3) to predict the participants’ relationship status (0 = single, 1 = romantic partner). Results suggested that perfectionism focused on the perceived perfectionistic expectations from the partner is associated with the increased likelihood to be single, a result that confirmed the close association between maladaptive perfectionism and relevant aspects of romantic relationships
Apoptosis: a relevant tool for anticancer therapy
No full textApoptosis is a form of cell death that permits the removal of damaged, senescent or unwanted cells in multicellular organisms, without damage to the cellular microenvironment. Defective apoptosis represents a major causative factor in the development and progression of cancer. The majority of chemotherapeutic agents, as well as radiation, utilize the apoptotic pathway to induce cancer cell death. Resistance to standard chemotherapeutic strategies also seems to be due to alterations in the apoptotic pathway of cancer cells. Recent knowledge on apoptosis has provided the basis for novel targeted therapies that exploit apoptosis to treat cancer. These new target include those acting in the extrinsic/intrinsic pathway, proteins that control the apoptosis machinery such as the p53 and proteosome pathway. Most of these forms of therapy are still in preclinical development because of their low specifity and susceptibility to drug resistance, but several of them have shown promising results. In particular, this review specifically aims at providing an update of certain molecular players that are already in use in order to target apoptosis (such as bortezomib) or which are still being clinically evaluated (such ONYX-015, survivin and exisulind/aptosyn) or which, following preclinical studies, might have the necessary requirements for becoming part of the anticancer drug programs (such as TRAIL/Apo2L, apoptin/VP3)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
