Dental non-metric traits of Han and Zhuang people / 解剖学报

[Abstract] Objective To investigate the relationship between the Han, Zhuang and the World populations by comparing the frequency of dental non-metric traits. Methods From 2015 to 2019, ten dental non-metric traits were sampled from He’nan, Jiangsu and Guangxi Zhuang Autonmous Region, with sample size of 1785(674 He’ nan, 547 Jiangsu, 388 Guangxi Han, 176 Guangxi Zhuang). Principal component analysis, multidimensional scaling and neighbor network were carried out. Results East Asian populations could be clearly divided into two major groups, Northeast Asian and Southeast Asian. Han and Zhuang populations were close to the Northeast Asian populations, but were far from the Southeast Asian populations. There were also some north-south differences within Han populations. Conclusion Both Sundadonty and Sinodonty are existed in East Asian populations. Han and Zhuang populations dental non-metric traits are closer to the Sinodonty.

Application of SifaInDel 45plex System in the Han and Mongolian Populations / 法医学杂志

OBJECTIVES@#To investigate the genetic polymorphism of InDel loci in SifalnDel 45plex system in the Han population in Jiangsu Province and the Mongolian population in Inner Mongolia, and to evaluate the effectiveness of the system in forensic medicine.@*METHODS@#SifaInDel 45plex system was used for genotyping in blood samples of 398 unrelated individuals from the above two populations, and allele frequencies and population genetic parameters of the two populations were calculated respectively. Eight intercontinental populations in the gnomAD database were used as reference populations. The genetic distances between the two studied populations and eight reference populations were calculated based on the allele frequencies of 27 autosomal-InDels (A-InDels). The phylogenetic trees and multidimensional scaling (MDS) analysis diagrams were constructed accordingly.@*RESULTS@#Among two studied populations, the 27 A-InDels and 16 X-InDels showed no linkage disequilibrium between each other and the allele frequency distributions were in Hardy-Weinberg equilibrium. The CDP of the 27 A-InDels in two studied populations were all higher than 0.999 999 999 9, and the CPEtrio were all less than 0.999 9. The CDP of the 16 X-InDels in Han in Jiangsu and Mongolian in Inner Mongolia female and male samples were 0.999 997 962, 0.999 998 389, and 0.999 818 940, 0.999 856 063, respectively. The CMECtrio were all less than 0.999 9. The results of population genetics showed that the Jiangsu Han nationality, Inner Mongolia Mongolian nationality and East Asian population clustered into one branch, showing closer genetic relationship. The other 7 intercontinental populations clustered into another group. And the above 3 populations displayed distant genetic relationships with the other 7 intercontinental populations.@*CONCLUSIONS@#The InDels in the SifaInDel 45plex system have good genetic polymorphism in the two studied populations, which can be used for forensic individual identification or as an effective complement for paternity identification, and to distinguish different intercontinental populations.

Allometrically adjusted handgrip strength and chair stand test cut points to identify sarcopenia in older Portuguese adults / Pontos de corte da força de preensão manual e teste de sentar e levantar da cadeira ajustados alometricamente para identificar sarcopenia em idosos portugueses

ABSTRACT Absolute muscle strength or adjusted by body mass index (BMI) are useful to identify sarcopenia. However, these values are not accurate for older adults with extreme body sizes because the nonlinear relationship between strength and body size. The purpose was to determine cut-off points for identify sarcopenia in older adults using allometric coefficients to normalise handgrip strength (HGS) and 30-sec chair stand test (30-s CST) by body size. Allometric exponents were proposed with log-linear models for body-size variables (body mass, height and BMI). The remotion of body-size effect on muscle strength with allometric normalisation was tested by partial correlation. Cut-off points for low muscle strength were established by ROC curve and Youden index considering functional limitation (six-minute walk test<400m). Allometric exponents provided for body-size variables range from -0.01 to 2.28 (HGS) and -0.27 to 0.21 (30-s CST). The effect of body size on muscle strength was removed with allometric normalisation (r<0.30). Cut-off points accuracy was always adequate (AUC≥0.78; p<0.001). In conclusion, cut-off points of HGS and 30-s CST allometrically normalised were proposed to identify sarcopenia in Portuguese older adults and allometry maintained adequate the accuracy (AUC>70%). Allometry removed influence of body size on the expression of HGS and 30-s CST and permits evaluate muscle strength regardless of body-size.

RESUMO A força muscular absoluta ou ajustada pelo índice de massa corporal (IMC) é útil para identificar a sarcopenia. No entanto, esses valores não são precisos para idosos com tamanhos corporais extremos devido à relação não linear entre força e tamanho corporal. O objetivo foi determinar os pontos de corte para identificar a sarcopenia em idosos usando coeficientes alométricos para normalizar a força de preensão manual (FPM) e teste de sentar e levantar da cadeira em 30 segundos (30-s CST) por tamanho corporal. Os expoentes alométricos foram propostos com modelos log-lineares para variáveis de tamanho corporal (massa corporal, estatura e IMC). A remoção do efeito do tamanho corporal na força muscular com normalização alométrica foi testada por correlação parcial. Os pontos de corte para baixa força muscular foram estabelecidos pela curva ROC e índice de Youden considerando a limitação funcional (teste de caminhada de seis minutos<400m). Os expoentes alométricos fornecidos para variáveis de tamanho corporal variam de -0,01 a 2,28 (FPM) e -0,27 a 0,21 (30-s CST). O efeito do tamanho corporal na força muscular foi removido com normalização alométrica (r<0,30). A precisão dos pontos de corte sempre foi adequada (AUC≥0,78; p<0,001). Em conclusão, foram propostos pontos de corte para FPM e 30-s CST normalizados alometricamente para identificar sarcopenia em idosos portugueses e a alometria manteve a precisão adequada (AUC>70%). A alometria removeu a influência do tamanho corporal na expressão da FPM e 30-s CST e permite avaliar a força muscular independentemente do tamanho corporal.

Multiple comparisons of diversity indices invaded by Lantana camara / Análises múltiplas de índices de diversidade da invasiva Lantana camara

Abstract Current study assessed the impact of Lantana camara invasion on native plant diversity in Pothohar region of Pakistan. The approach used for study was random samplings and comparisons of diversity indices [number of species (S), abundance (N), species richness (R), evenness (Jꞌ), Shannon diversity index (Hꞌ) and Simpson index of dominance (λ)] with two categorical factors i.e., invaded and non-invaded (control). Control plots harboured by an average of 1.74 more species/10m2. The control category was diverse (Hꞌ=2.56) than invaded category (Hꞌ=1.56). The higher value of species richness in control plots shows heterogeneous nature of communities and vice versa in invaded plots. At multivariate scale, ordination (nMDS) and ANOSIM showed significant magnitude of differences between invaded and control plots at all sites. The decrease in studied diversity indices in invaded over control sites indicated that plant communities become less productive due to Lantana invasion.

Resumo O presente estudo avaliou o impacto da invasão de Lantana camara na diversidade de plantas nativas na região de Pothohar, no Paquistão. A abordagem utilizada para o estudo foram a amostragem aleatória e a comparação de índices de diversidade, como número de espécies (S), abundância (N), riqueza de espécies (R), equitabilidade (Jꞌ), índice de diversidade de Shannon (Hꞌ) e índice de dominância de Simpson (λ), com dois fatores categóricos, ou seja, invadidos e não invadidos (controle). As parcelas não invadidas tinham, em média, 1,74 espécie a mais / 10 m2 que parcelas invadidas. A categoria controle foi mais diversa (Hꞌ = 2,56) do que a categoria invadida (Hꞌ = 1,56). O maior valor da riqueza de espécies em parcelas de controle mostra a natureza heterogênea das comunidades, e vice-versa, em parcelas invadidas. Na escala multivariada, ordenação (nMDS) e ANOSIM mostraram magnitude significativa das diferenças entre as parcelas invadidas e controle em todos os locais. A diminuição nos índices de diversidade estudados em locais invadidos por controle indicou que as comunidades de plantas se tornam menos produtivas por causa da invasão de Lantana.

Confrontando estruturas de valores: um estudo comparativo entre PVQ-40 e PVQ-21 / Confronting structures of values: a comparative study between PVQ-40 and PVQ-21

Esforços têm sido realizados para desenvolver escalas de mensuração capazes de traduzir o constructo e a estrutura de valores. Entre as existentes estão as escalas SVS - Schwartz Value Survey e o Portrait Values Questionnaire com 40 e 21 itens (respectivamente PVQ-40 e PVQ-21). As duas formas desse último questionário apresentam aplicabilidade mais ampla, por possuírem uma menor quantidade de itens e terem os itens redigidos de forma menos abstrata do que a SVS. Não foram encontrados, no entanto, estudos que comparem as duas escalas quanto à estrutura de valores obtida a partir de sua aplicação, objetivo a que este estudo se propôs a alcançar. A pesquisa foi realizada com uma amostra de 217 estudantes universitários, aos quais foram aplicadas as escalas PVQ-40 e PVQ-21, em dois momentos distintos. Os dados foram tratados mediante Análise de Escalonamento Multidimensional Confirmatória Fraca. Os resultados indicaram que ambas as escalas são equivalentes quanto à estrutura de valores bidimensional e bipolar, porém foram encontradas divergências entre ambas quanto à distribuição no espaço dos valores dos tipos Estimulação, Autodeterminação, Poder e Realização. (AU)

Several measurement scales have been developed in order to translate constructs and their value structure. Among these are the Schwartz's Values Survey (SVS) and the Portrait Values Questionnaire with 40 and 21 items, respectively (PVQ-40 and PVQ-21). The two forms of the questionnaire allow a wider use because they have showed fewer and less abstract items compared to the SVS, however, there have not been found studies that compare both instruments regarding their value structure. Therefore, this is the objective of the present study. A sample of 217 university students answered the PVQ-40 and the PVQ-21 at two different moments in time. The data were analyzed by Confirmatory Multidimensional Scaling. The results indicate that both scales are equivalent in terms of bidimensional and bipolar value structures, however, differences were found with regard to the spatial distribution of values measuring Stimulation, Self-Direction, Power and Achievement.

Bi-dimensional semantic scales: the embodied maps of meanings / Escala semántica bidimensional: La corporeidad de los mapas de significados

Osgood developed the semantic differential to bridge the phenomena from semantics and perception, and we applied its modified version to investigate current issues in cognitive science. We used two-dimensional rather than one-dimensional space to position nominal word items, and subjected data to multidimensional scaling (MDS). In Experiment 1 (paper-and-pencil) participants judged concrete and abstract nouns on seven bipolar semantic differential scales in three perceptual modalities: visual, auditory and touch. Six months later, in Experiment 2 (computer-assisted), the same participants mapped the same ten nouns on a balanced subset of two-dimensional planes. Our findings support the hypothesis that semantic space is physically constrained. MDS over one-dimensional ratings from Experiment 1 resulted in a particular two-dimensional solution. This two-dimensional combination was very similar to one of the raw two-dimensional maps from Experiment 2. We then concluded that this particular raw two-dimensional map is highly informative, as it captures almost all differences between word items in the given set of perceptual opposites. Its informativeness proved to be robust to experimental administration (paper-and-pencil vs. computer-assisted) and scale-orientations (horizontal vs. vertical). Recent theories, such as Barsalou's perceptual theory of knowledge, capture the tradition of conceptualizing all knowledge as inherently perceptual. Our results strongly support these theories.

Osgood desarrolló el diferencial semántico para investigar los fenómenos desde la semántica y la percepción, y aplicamos su versión modificada para investigar temas actuales en ciencia cognitiva. Utilizamos dos dimensiones en lugar de un espacio unidimensional para posicionar palabras nominales y datos sujetos a escalamiento multidimensional (MDS). En el experimento 1 (papel y lápiz) participantes consideraron sustantivos concretos y abstractos en siete escalas de diferencial semántico bipolar en tres modalidades per-ceptuales: visual, auditivo y táctil. Seis meses más tarde, en el Experimento 2 (asistida por ordenador), los mismos participantes asignaron los mismos diez sustantivos en un subconjunto equilibrado de planos bidimensionales. Nuestros resultados apoyan la hipótesis de que el espacio semántico está limitado físicamente. Las calificaciones unidimensionales sobre MDS del Experimento 1 dieron como resultado una solución de dos dimensiones particular. Esta combinación de dos dimensiones fue muy similar a uno de los mapas de dos dimensiones en bruto del Experimento 2. Se concluyó que este mapa particular de dos dimensiones es altamente informativo, ya que captura casi todas las diferencias entre las palabras en el conjunto dado de los opuestos perceptuales. Esta información demostró ser sólida a la administración experimental (papel y lápiz versus asistida por computador) y las orientaciones de la escala (horizontal y vertical). Teorías recientes, como la teoría del conocimiento perceptual de Barsalou, captura la tradición de la conceptualización del conocimiento como inherentemente perceptual. Nuestros resultados apoyan firmemente estas teorías.

Diseño de la Escala Multidimensional de Trastornos Afectivos (emta): análisis psicométrico de confiabilidad y validez / Design of multidimensional scale emta affective disorders: psychometric analysis of reliability and validity

El propósito de esta investigación fue construir y validar una escala que mide trastornos afectivos. La muestra piloto estuvo conformada por 100 sujetos de la Corporación Universidad de la Costa (Barran-quilla, Colombia): 81% mujeres y 19% hombres, con edades entre 18 y 44 años. Inicialmente, la escala contenía en la Subescala de Depresión los ítems 1-57 y en la Subescala de Manía los ítems 5893. La escala final cuenta con la evaluación de síntomas depresivos (ítems 1-47); la segunda de ellas busca evaluar, a su vez, síntomas de corte maniaco (ítems 52-80). Los síntomas contemplados en los ítems 48 al 51 y 81 al 85, respectivamente, buscan evaluar intensidad y cronicidad de una manera más específica. El procesamiento estadístico de los datos se realizó con el software SPSS. Se estimaron los índices Alfa de Cronbach obtenidos en la Subescala de Depresión (a: 0.942) y en la Subescala de Manía (a: 0.834). Adicionalmente se estimaron los niveles de correlación ítem - escala y se desarrolló un análisis factorial para profundizar en la valoración de la validez del constructo. Igualmente se generaron rangos de clasificación de los puntajes obtenidos; para identificar el nivel de Manía o Depresión de los sujetos, cada una de la subescalas evalúa rangos de nivel bajo, medio y alto. En el caso de la Subescala de Depresión, se pudo identificar que los rangos de clasificación están a un nivel bajo para el 81% de los casos y medio para el 19%. En la Subescala de Manía, los rangos de clasificación están a un nivel bajo para el 82% de los casos y medio para el 18%, los cuales son consistentes con la naturaleza de la muestra piloto, que fue de corte no clínica.

The purpose of this research was to construct and validate a scale for measuring affective disorders. The sample was taken with 100 students of the Corporación Universidad de la Costa (Barranquilla, Colombia): 81% women and 19% men between 18 and 44 years of age. Initially, the scale contained items from 1 to 57 in the Depression Subscale and items from 58 to 93 in the Mania Subscale. The final scale has items (from 1 to 47) to valuate depressive symptoms and others (from 52 to 80) for mania symptoms. Items from 48 to 51 and from 81 to 85 were made to valuate intensity and chronicity in a more specific way. Statistical data processing came ahead from expected with the SPSS software. Indicating the Cronbach Alpha index obtained in the Depression Subscale, that was equal to (a: 0.942) and in the Mania Subscale was equal to (a: 0.834). In addition, correlated values were estimated from item-scale and a factorial analysis was developed to reach deep in the grade validity of the construct, in order to identify the subjects' level of Mania or Depression. Each subscale valuates low, medium and high ranges. With the Depression Subscale 81% of the sample showed low level results and 19% showed medium level results. With the Mania Subscale at 82% of the sample, showed low level results and 18% showed medium level results, which are consistent with the nature of the original sample from non-clinical approach.

Especificidad de forófito y preferencias microambientales de los líquenes cortícolas en cinco forófitos del bosque premontano de finca Zíngara, Cali, Colombia / Phorophyte specificity and microenvironmental preferences of corticolous lichens in five phorophyte species from premontane forest of Finca Zíngara, Cali, Colombia)

Phorophyte specificity and microenvironmental preferences of corticolous lichens in five phorophyte species from premontane forest of Finca Zíngara, Cali, Colombia). Lichenized fungi or lichens are organisms that have been little studied in the tropics and which distribution is affected by microenvironmental factors and substrate characteristics. The present study aimed to identify phorophyte specificity and microenvironmental preferences of corticolous lichens in five phorophyte species from premontane forest of the farm Finca Zingara in Cali, Colombia. For this, five individuals were selected from five tree species (phorophytes). Lichen species present in a 0.50x0.20m² quadrant located in the trunk of each tree at a height of 1.3m were identified. Substrate parameters such as bark pH, Diameter Breast Height (DBH) and bark structure were measured. Also, microenvironmental factors including temperature, humidity and irradiance were determined. In order to detect phorophyte preferences, a non-metric multidimensional scaling (NMS) and indicator species analysis were made. Spearman correlation analysis was used to assert the relationship between environmental variables and groupings found in the NMS. A total of 69 species of lichens were found, of which 37 were identified to species, 18 to genera and 14 were not determined because they were sterile or had no spores. NMS showed that some individuals of the same tree species were grouped alongside the analysis dimensions, and they were related with the factors of light intensity, temperature and DBH. Only three lichens with preference for certain tree species were found (Arthonia microsperma by Meriania sp., Cladonia ceratophylla and sorediado 8 by Clusia sp.), suggesting absence of phorophyte preferences. Thus, it can be concluded that lichens from the study area do not show phorophyte preference, but their distribution is affected by light, temperature and DBH. Rev. Biol. Trop. 60 (2): 843-856. Epub 2012 June 01.

El objetivo de este trabajo fue evaluar la especificidad de forófito y las preferencias microambientales de los líquenes cortícolas en el Bosque de la Finca Zíngara (Cali, Colombia). Asimismo, se seleccionaron cinco individuos de cinco especies de árboles. Además, se identificaron las especies de líquenes presentes en un cuadrante de 0.50x0.20m2 ubicado en el tronco de cada árbol a 1.3 m de altura. También, se midieron parámetros microambientales como pH de la corteza, diámetro a la altura del pecho (DAP), estructura de la corteza, humedad relativa e irradianza. Para detectar las preferencias de forófito, se realizó un escalamiento no métrico multidimensional (NMS) y un análisis de especies indicadoras. Luego se efectúo un análisis de correlación de Spearman para evaluar la relación entre las variables ambientales y los agrupamientos encontrados en el NMS. Se encontraron 69 especies de líquenes, de los cuales 37 fueron determinados hasta especie, 18 hasta género y 14 no fueron determinados. El resultado del NMS mostró que algunos individuos de la misma especie de árbol se agruparon a lo largo de las dimensiones del análisis, y están relacionados con los factores intensidad de luz, temperatura y DAP. Sólo tres especies mostraron preferencia por ciertas especies de árboles (Arthonia microsperma por Meriania sp., Cladonia ceratophylla y sorediado 8 por Clusia sp.), lo cual sugiere ausencia de preferencias de forófito.

High prevalence of the GSTM3*A/B polymorphism in sub-Sarahan African populations

A 3-bp insertion/deletion polymorphism in intron 6 of GSTM3 (rs1799735, GSTM3*A/*B) affects the activity of the phase 2 xenobiotic metabolizing enzyme GSTM3 and has been associated with increased cancer risk. The GSTM3*B allele is rare or absent in Southeast Asians, occurs in 5-20 percent of Europeans but was detected in 80 percent of Bantu from South Africa. The wide genetic diversity among Africans led us to investigate whether the high frequency of GSTM3*B prevailed in other sub-Saharan African populations. In 168 healthy individuals from Angola, Mozambique and the São Tomé e Príncipe islands, the GSTM3*B allele was three times more frequent (0.74-0.78) than the GSTM3*A allele (0.22-0.26), with no significant differences in allele frequency across the three groups. We combined these data with previously published results to carry out a multidimensional scaling analysis, which provided a visualization of the worldwide population affinities based on the GSTM3 *A/*B polymorphism.

Escala revisada de valores relativos ao trabalho - EVT-R / Revised work values scale - WVS-R

Os valores do trabalho são os princípios que guiam a vida do indivíduo no trabalho. No Brasil, uma escala que já foi amplamente utilizada em pesquisas é a Escala de Valores relativos ao Trabalho (EVT). O objetivo do primeiro estudo foi realizar o teste confirmatório da estrutura empírica da escala. Uma amostra de 790 profissionais respondeu ao instrumento. Os resultados apontaram a adequação do modelo, mas a representação dos tipos motivacionais foi limitada. Para suprir esta lacuna, a escala foi revisada e validada no segundo estudo. A nova escala foi aplicada em uma amostra de 412 trabalhadores. Os resultados da análise fatorial e do escalonamento multidimensional apontam que houve melhoras significativas na estrutura empírica da escala. As implicações são discutidas.

Work values are guiding principles in the work life of a person. In Brazil, a broadly used scale is the Work Values Scale (WVS). The purpose of the first study was to do a confirmatory test of the empirical structure of WVS. A sample of 790 workers answered this instrument of research. The results showed a good fit of the structure, but also indicated a poor representation of some motivational types. The scale was revised and validated in the second study. More items were developed and the new scale was applied in a sample of 412 workers. The factor analysis and multidimensional scaling results showed an improvement of the empirical structure. Implications are discussed.

An Analysis of Variance in Students' Self-Evaluation Attitudes for Autonomous Learning / 医学教育

The purpose of this study was to examine statistical methods for assessing variance in students' learning attitudes over 2 months. The students' learning attitudes, measured by tutorial assessment sheets, were analyzed quantitatively by multidimensional scaling and cluster analysis. Items on the tutorial assessment sheets were divided throughout the practice period into two axes of speculation (behavior and partnership). At the initial and medium-term stages of this practice, the dispersion of student's consciousness for given assessments was able to determine the quantity. We could then determine the quantity of recognizing the importance of topics to learn, and consciousness for learning was a feature often found at the end of this practice.
