Acoustic Radiation Force Impulse (ARFI) Elastography in Autoimmune and Cholestatic Liver Diseases

Acoustic Radiation Force Impulse (ARFI) Elastography in Autoimmune and Cholestatic Liver Diseases

Table 2 shows mean ARFI values of the different dis- eases. In all patients overall and in patients with AIH or with overlap syndrome a significant correlation of hepatic fibrosis and ARFI shear wave velocities could be demon- strated. 20/31 (65%) of the AIH patients were examined before starting an immunosuppressive treatment. The sub- group of 26 patients with PBC containing only fibrotic stages F ≤ 3 revealed no correlation of ARFI measure- ments with the Ishak fibrosis score (r = 0.019, p = 0.927) (Figure 2). In a subanalysis of those 44 patients only hav- ing F ≤ 3 and no PBC, a correlation between fibrosis and ARFI could be revealed (r = 0.540, p < 0.001).

Asociación entre conducta suicida y síntomas de anorexia y bulimia nerviosa en escolares de Boyacá Colombia

Asociación entre conducta suicida y síntomas de anorexia y bulimia nerviosa en escolares de Boyacá Colombia

This research aimed to establish the relationship between eating disorders and suicidal ideation and attempt, in adolescents from eighth to eleventh grade of educational institutions in three cities of Boyacá (Colombia). The study conducted was empirical and used quantitative methodology. A descriptive strategy was implemented using a cross-sectional design. The sample consisted of 1292 participants, selected by stratified probability sampling. The instruments applied were firstly, the Positive and Negative Suicidal Ideation PANSI Inventory (Osman, Gutiérrez, Kopper, Barrios and Chiros, 1998) to inquire about the protective and risk factors for suicidal ideation and the presence of suicidal act. Secondly, the Sick Control on Fat Food -SCOFF Questionnaire (Morgan, Reid & Lacey, 1999) to carry out a screening for eating disorders. Thirdly, a socio- demographic survey designed by the authors, to characterize the sample of participants. Results show that out of the total number of young people who participated in the study, 230 (17.8%) consider suicide as an alternative. The research identified low but significant correlation between eating disorders and negative PANSI (rs = .19 and p = 0.00), suggesting that the higher the presence of alarm signals of eating disorders, the higher the risk factors for suicidal ideation.

Trophic specialization and morphological divergence between two sympatric species in Lake Catemaco, Mexico

Trophic specialization and morphological divergence between two sympatric species in Lake Catemaco, Mexico

In the present study, a significant correlation between stable isotopes and ecomophology was observed, in contrast to the latter and diet content. In this respect, diet analysis provides a snapshot of fish feed- ing habits and shows temporal variations that could be difficult to ap- proach. Stable isotopes analysis provides a time- integrated indicator of energy resources (Vander Zanden, Casselman, & Rasmussen, 1999). When combined, these two sources of evidence provide robust ana- lytic tools that can be used to better understand the consumption and assimilation of food by fish (Vander Zanden & Vadeboncoeur, 2002). Stable carbon and nitrogen isotope ratios have been widely used to provide a time- integrated perspective of feeding relationships (Vander Zanden, Casselman, et al., 1999). The nitrogen stable isotope signature ( δ 15 N) increases proportionally to the trophic position in the food web

Asociación entre religiosidad y síntomas depresivos en  adolescentes escolarizados

Asociación entre religiosidad y síntomas depresivos en adolescentes escolarizados

Background: Several studies report a significant association between religiosity and depressive symptoms among adolescents; but, other researches do not. Up to date, this relation has not investigated in adolescent students who live in a violent and low-income country. Objective: To establish the correlation between religiosity and depressive symptoms among students in Cartagena, Colombia. Method: A cross-sectional study was done with participation of adolescents aged between 13 and 17 years old. Students completed two scales: the five-item form of the Francis scale of attitude toward Christianity (Francis-5), which asked about God, Jesus and prayer (higher scores suggest higher religiosity); and the WHO Well-Being Index (WHO-5) inquired depressive symptoms last two weeks (lower scores suggest higher depressive symptoms). It was accepted as a significant Pearson correlation (rho, r) a coefficient value higher than 0.20. A total of 1,730 students answered the questionnaires. The mean age was 14.7 (SD = 1.2). According to gender, 912 (52.7%) students were girls; and 818 (47.3%), boys. Francis-5 showed high internal consistency, coefficient alpha of 0.909; and coefficient omega of 0.910. WHO-5 presented coefficient alpha of 0.757; and omega of 0.759. The Francis-5 scores were between zero and twenty (Mean = 18.2, SD = 3.0, median = 20, mode = 20); and WHO-5 scores, between zero and fifteen (Mean = 10.2, SD = 3.1, median = 10, mode = 10). Religiosity had not significant correlation with depressive symptoms (r = 0.080). Conclusions: Religiosity is not associated with depressive symptoms among adolescent students in Cartagena, Colombia.

Prospective and regular ELT teachers digital empowerment and self efficacy

Prospective and regular ELT teachers digital empowerment and self efficacy

ABSTRACT: This study examines the possible correlation between (a) digital em- powerment and their teacher self-efficacy in general, (b) the level of prospective ELT teachers’ digital empowerment and their teacher self-efficacy beliefs, (c) the level of regular ELT teachers’ digital empowerment and their self-efficacy beliefs, and tries to see if prospective ELT teachers and regular ELT teachers differ in digital empower- ment and their self-efficacy beliefs. A statistically significant correlation exits between digital empowerment and teacher self-efficacy in foreign language teaching context. All the same, a statistically significant correlation between the level of prospective ELT teachers’ digital empowerment and their teacher self-efficacy beliefs has been observed as well as the significant correlation coefficient for their mentors. Additionally, we have seen correlations between self-efficacy and (a) motivation, (b) technical availability and utilization, and (c) competency in the use of technology. Moreover, it was found that prospective ELT teachers and regular ELT teachers only differ in digital empowerment but in self-efficacy. The only difference was observed in technical availability and uti- lization in favor of regular teachers (mentors). Therefore, it is concluded that foreign language teachers should become acquainted with digital technologies for more effective classroom teaching. To do so, motivation with positive attitudes towards information technologies, and feeling competent through more practice in pre-service foreign language teacher training programs at least in order to improve their self-efficacies by creating a positive classroom environment should be provided.

The inflammatory response to colloids and crystalloids used for pump priming during cardiopulmonary bypass

The inflammatory response to colloids and crystalloids used for pump priming during cardiopulmonary bypass

From a clinical point of view, CPB has been associated with a large variety of clinical symp- toms, 1 and the extent of their intensity has been correlated with the levels of cytokines and comple- ment, and the severity of the SIRS. 2–4 However, we were not able to find a significant correlation between plasma levels (IL-6, IL-8, and TNF-a) and peri-operative variables. As for the presence of relevant adverse effects related with postpump syndromes (respiratory insufficiency, levels of CPK-MB, need for inotropic support, units of donor blood, need for blood transfusion etc.), there were no differences between the two groups. Chello et al. 24 did not find any correlation between the levels of cytokines and the adverse effects.

Expression profiling of rectal tumors defines response to neoadjuvant treatment related genes.

Expression profiling of rectal tumors defines response to neoadjuvant treatment related genes.

To confirm the findings obtained in the expression array, qRT- PCR was performed for selected genes in 24 LARC samples: responder (n = 10) and non responder (n = 14). Samples of 2 patients (6 and 9) were not analyzed because of poor RNA quality. Among the genes of the c-Myc apoptosis pathway, c-Myc, Mapk9 (one of the main kinases involved in the phosphorylation of c- Myc), and the Id1 and Stmn1 genes, downstream targets of c-Myc, were selected to analyze their expression by real-time RT-PCR. In addition, we analysed other genes related to c-Myc apoptosis and proliferation (Tp53, P53csv, Pola1, Cdkn1a, Top1mt, Rrm1, and Ska2), as well as genes involved in angiogenesis (Mmp12), and transport (Abcb7, and Chmp4b). Highly concordant results were obtained for all these genes with statistically significant differences between these two groups of LARC patients (Figure S2).

Ethical values in college education: A mixed-methods pilot study to assess Health Sciences students' perceptions

Ethical values in college education: A mixed-methods pilot study to assess Health Sciences students' perceptions

Results: After 24 conversational interviews, three main thematic blocks (coinciding with the three subscales of the questionnaire) were identified: “ attitudes for harmony in human relations ” , “ construction of the self ” and “ rules and regulations ” . A total of 246 students completed a questionnaire with 39 items. The total scores ranged from 93 to 152 points, with an average score of 122.72 ± 10.64 points. Responsibility, the basic rules of education and respect were perceived as the two most important values, whereas solidarity and social participation as the least important. Results showed a significant positive linear correlation between total score on the questionnaire and age and social desirability. Age was also a significant predictor for the total score and the subscale score “ rules and regulations ” . The students´ responses seemed to be conditioned by the degree of social desirability that they present. Conclusions: The ad-hoc questionnaire captured the maintenance of high ethical values in our college

Letters in spatial and resource sciences, 10(1): 129-139

We have evaluated the capacity of the Moran’s I test for spatial correlation to serve as a tool for detecting potential complementary bidding behavior on public contracts. The test was applied to bids submitted by the so-called Swedish asphalt cartel, which was active during the 1990s. Based on data from procurements conducted during the cartel’s period of activity and after its detection in 2001, the Moran’s I correctly indicates complementary bidding behavior when such behavior is likely to be present and rejects such behavior when it’s less likely to exist. On the basis of the results presented herein and our proposed 4 step procedure, we argue that the Moran’s I test statistic may be used as a first indicator of complementary bidding behavior by organizations such as national antitrust authorities. Its main advantage is its relative simplicity and low data requirements. However, we readily acknowledge that much more evidence than just a significant Moran’s I value would be required to support legal proceedings.

Systemic to pulmonary collateral flow in patients with palliated univentricular heart physiology: measurement using cardiovascular magnetic resonance 4D velocity acquisition

Systemic to pulmonary collateral flow in patients with palliated univentricular heart physiology: measurement using cardiovascular magnetic resonance 4D velocity acquisition

This amount of left-to-right shunting is considerable albeit not massive, and hence it was no surprise that we were unable to find any correlation of SPCF magnitude with single ventricle sizes or systolic function (i.e., end-diastolic/end-systolic volumes and ejection fraction) for either patient group. This is in contrast with findings published recently by Whitehead and colleagues who did observe such correlation [2] but available sample sizes from both studies (<20 subjects for each respective patient group) may be too small to allow meaningful conclusions in either direction in terms of relevance of SPCF for progressive ventricular dilatation and dysfunction in Fontan patients. This will require much larger numbers and a multicenter study design with consistent operator-independent flow

Is the level of eye hand coordination and executive functioning related to performance in para table tennis players? – An explorative study

Is the level of eye hand coordination and executive functioning related to performance in para table tennis players? – An explorative study

well as the ratio scores) and the table performance outcome (i.e. competition rating score) were firstly evaluated by calculating Spearman’s correlation coefficients and partial correlation coefficient with training volume as a controlling variable. Hinkle’s rule of thumb was used for the interpretation of the correlation coefficients’ sizes (Hinkle, Wiersma, & Jurs, 2003). Secondly, scatter plots were used to explore the players’ profiles regarding the level of eye- hand coordination and executive functioning and the level of performance. Only the total score of the D- KEFS Design Fluency test and the outcomes of Trail B of the Trail Making test and color-word condition of the Stroop test were included for this exploration to reflect the executive functioning. Alpha was set at 0.05 for significance for the inferential analyses; the alpha was not adjusted (i.e. lowered) for the multiple testing because of the explorative character of this pilot study. This is supported by Hopkins (2000) stating that the cut-off of 5% can be too stringent for a decision limit in athletes.

Comparative analysis between trichinoscopy and artificial digestion, in experimental infections with low number of larvae

Comparative analysis between trichinoscopy and artificial digestion, in experimental infections with low number of larvae

ABST RACT : Two direct methods for the diagnosis of trichinellosis were compared: trichinoscopy and artificial digestion. Muscles from 35 Wistar rats infected per os with different inocula (10, 50, 100, 200, 300, 400 and 500 encysted larvae) of Trichinella spiralis were examined. The follow ing muscles: diaphragm, tongue, masseters, intercostals, triceps brachialis and cuadriceps femoralis, were revised by trichinoscopy and all the samples were then processed by artificial digestion. 472.276 muscular larvae were recovered. The linear correlation between trichinoscopy and artificial digestion was very high and significant (r=0.69; p<0.01; F=1.33; d.f.=1/ 418; P=0.248; p>0.05) showing that both methods for the detection of muscular larvae did not differ significantly, even in infected rats with lower number of larvae.

Correlation Dimension of Complex Networks

Correlation Dimension of Complex Networks

city (1920) whose shape is the result of a planning process and, accordingly, displays a gridlike road structure. Conversely, Oldenburg (Germany) is an old city whose foundation dates back to the twelfth century and whose road pattern is the result of a self-organized growth. In Figs. 3(c) and 3(d), we show their respective correlation sum functions. While the case of San Joaquin (c) evidences a scaling regime with a correlation dimension converging to 2 ( ¼ 1 : 83 0 : 1 for m ¼ 3), no scaling is found for the self-organized city of Oldenburg (d), suggesting that this latter network does not possess a well-defined dimen- sion. These different behaviors deepen in the recently observed structural differences between cities that have grown according to different evolutionary mechanisms [30,31]. In the Supplemental Material [32] we include additional analysis and estimation of the correlation di- mension of other real world examples including techno- logical (Internet at the autonomous system level [33] and the Italian power grid [34]) and road (San Francisco [29] and USA [35]) networks. Their corresponding analysis yields a well-defined and justified correlation dimension.

Correlation methods in cutting arcs

Correlation methods in cutting arcs

Abstract The present work applies similarity theory to the plasma emanating from transferred arc, gas-vortex stabilized plasma cutting torches, to analyze the existing correlation between the arc temperature and the physical parameters of such torches. It has been found that the enthalpy number significantly influence the temperature of the electric arc. The obtained correlation shows an average deviation of 3 % from the temperature data points. Such correlation can be used, for instance, to predict changes in the peak value of the arc temperature at the nozzle exit of a geometrically similar cutting torch due to changes in its operation parameters.

International R&D spillovers and unobserved common shocks

International R&D spillovers and unobserved common shocks

Two articles by Belitz and Molders (2013) and Ertur and Musolesi (2013) have analyzed the role of spillover variables at the aggregate level into a common factor framework by comparing their results with those of a CH approach, which does not account for unobserved common shocks (results from a spatial error model are also compared in Ertur and Musolesi (2013)). Belitz and Molders (2013) use the LP weighting scheme and data on the number of patent applications for 77 countries from 1990-2008 to study the knowledge transfer via trade, FDI, internationalization of business R&D, imports of high tech goods and R&D of foreign owned companies; whereas Ertur and Musolesi (2013), using the CH dataset, study the international knowledge transfer as a decreasing function of geographical distance from foreign economies. Both papers have provided evidence of significant international knowledge spillovers in common factor models, so that claim that international knowledge flows determine TFP in accordance with the findings of the literature on international R&D spillovers, even when unobserved common shocks are accounted for. However, despite their efforts to study the knowledge spillovers in a common factor framework, it seems that more information from their common factor models would be needed in order to know: i) to what extent their estimates are consistent and not seriously biased depending on the degree of cross-section dependence of the errors, which might be associated to the coefficients of the spillover variables; and ii) if in reality those coefficients are capturing knowledge spillovers alone rather than other effects.

Correlation between maximum isometric strength variables and specific performance of Brazilian military judokas

A study verified the association between handgrip strength and blood lactate concentration in national level male judokas during a competition, and significant inverse relation (p<0.05) was found between such variable, especially for the non-dominant hand, where increase in the lactate concentration and decrease in the handgrip strength were observed after the first, third, and fourth fight (Bonitch- Góngora et al., 2012). Another study analysed the correlation among judoka variables, finding association (p<0.05) between the VO 2max

Factors associated with the positive impact of caring for elderly and dependent relatives / Javier López, Jesús López Arrieta and María Crespo

On the one hand, caregiving satisfaction showed a significant direct correlation (Tables 1– 3) with caregiver’s age, better previous and current affective relationship with the care recipient, daily hours as caregiver, being caregivers by own initiative, use of religion as a coping strategies. While on the other hand, there was a significant inverse correlation between caregiving satisfaction and being a female caregiver or an active worker, monthly caregiver’s incomes, have a kinship with the care recipient different than spouse or children, have a more frequent desire to institutionalize the patient, being a caregiver by family imposition or because he was the only person to do it, use of venting or self-blame as coping strategies, levels of burden, depression, trait anger, more psychotropic drugs consumption since caregiver status started and less leisure time since caregiver status started.

Polychaeta (Annelida) associated with Thalassia testudinum in the northeastern coastal waters of Venezuela

The significant correlation obtained between the number of Thalassia shoots and polychaete abundance confirms that the great- er biomass of this seagrass bears a greater macrofauna abundance and diversity, conse- quence of better protection against predators, which is consistent with the results of other studies (Stoner 1980, Lewis and Stoner 1983, Virnstein et al. 1983, Orth et al. 1984, Summerson and Peterson 1984, Schneider and Mann 1991, Connolly 1997). Further protec- tion is provided by other biogenic structures such as the emergent tubes of several spe- cies, mainly onuphids, as well as other sessile invertebrates present in the collections, such as porifera and anemones.

“Old stains, new perspective; Psychobiological models of personality and Rorschach”. / “Viejas manchas, nuevas miradas; Modelos psicobiológicos de la Personalidad y Rorschach”.

The Rorschach remains one of the worldwide reference psychological tests, about hundred years since its creation. Moreover, in recent years there are processes of deep transformation in the models, theories, diagnostic criteria and types of interventions in clinical psychology and psychiatry. In this process the neurosciences have a central role. It is, therefore, essential to assess the relevance and validity of the Rorschach in this new background. Part of these new paradigms is the dimensional psychobiological personality models. In this paper, we work with two of them, the Cloninger and Zuckerman personality models. This paper presents the correlations between Rorschach´s variables, TCI-140 and ZKPQ-50-CC scales in a representative (N=80) Uruguayan sample. We found that all dimensions of TCI-140 and ZKPQ-50-CC show significant correlations with at least 6 Rorschach variables. We conclude that the Rorschach test could be a relevant research and assessment tool, but some improvements are necessary.

Effect of Reduced Ankle Mobility on Jumping Performance in Young Athletes

Effect of Reduced Ankle Mobility on Jumping Performance in Young Athletes

Nakagawa et al. (2018), in his research, showed that increased joint amplitude of the ankle dorsiflexion movement is related to the improvement of the dynamic balance and the strength of the trunk muscles. In addition, the researchers found that the range of motion (ROM) of the ankle may be associated with the frontal projection angle of the knee. These results are similar to the data found in the present study, in which we found a positive and significant correlation in the projection angle of the knee to the front, in the knee to wall test, with the highest jumping capacity. These data are in line with previous findings that the mobility deficit may also impair movement (Cook et al., 2014), and expose athletes to the potential risks of injury to the Anterior Cruciate Ligament (ACL) (Hewett et al., 2005).
