Aproximación al ciberdelincuente desde la perspectiva del control social / Approaching the cybercriminal from a perspective of social control / Abordagem do criminoso cibernético a partir de uma perspectiva de controle social

El presente artículo aporta un acercamiento al ciberdelincuente identificando las características comunes en la personalidad de quienes delinquen en este escenario. Para llevar a cabo la investigación, se tomó una muestra de diecinueve expertos que forman parte de la Dirección de Investigación Criminal e INTERPOL, abordados por entrevista en profundidad. Los datos obtenidos fueron tratados desde un diseño hermenéutico con énfasis en la teoría fundamentada, por medio de tres fases elaboradas en análisis matricial de codificación abierta, selectiva y teórica; a partir de las cuales se establecen algunas de las tácticas del ciberdelincuente desplegadas en el ciberespacio a través de tecnologías de la información y las comunicaciones; su descripción desde el modelo big five y se identifican algunas de sus características como la falta de empatía, escrúpulos, incapacidad para el control de emociones, confianza y capacidad de innovar sus modus operandi(Sánchez y Robles, 2013). Finalmente, desde las teorías del control social se han estudiado el ciberdelito y los actos del ciberdelincuente de una manera formal que vela por encontrar estrategias de control del Estado, según González (2010), o informal, que busca los motivos que conducen a cometer delitos, como lo afirma López (2015), a partir de lo cual, al final, se presentan algunas recomendaciones.

This article provides an approach to cybercriminals by identifying the common characteristics in the personality of those who commit crimes in this scenario. In order to carry out the research, a sample of nineteen experts from the Criminal Investigation Directorate and INTERPOL were interviewed in depth. The data obtained were treated based on a hermeneutic design with emphasis on grounded theory, by means of three phases elaborated in matrix analysis of open, selective and theoretical coding; from which some of the tactics of cybercriminals deployed in cyberspace through information and communication technologies are established; their description based on the big five model and the identification of several of their characteristics such as lack of empathy, scruples, the inability to control emotions, confidence and the ability to innovate their modus operandi (Sánchez y Robles, 2013). Finally, theories of social control have studied cybercrime and the acts of cybercriminals in a formal way that seeks to find strategies to control the State, according to González (2010), or informally, seeking the motives that lead to committing crimes, as stated by López (2015), on the basis of which, at the end, some recommendations are presented.

Este artigo traz uma abordagem sobre os cibercriminosos, identificando as características comuns na personalidade de quem comete crimes nesse cenário. Para a realização da investigação foi recolhida uma amostra de dezanove peritos que integram a Direcção de Investigação Criminal e a INTERPOL, abordados através de entrevista em profundidade. Os dados obtidos foram tratados a partir de um desenho hermenêutico com ênfase na teoria fundamentada, por meio de três fases desenvolvidas em análise matricial de codificação aberta, seletiva e teórica; a partir da qual se estabelecem algumas das táticas cibercriminosas implantadas no ciberespaço através das tecnologias de informação e comunicação; A sua descrição baseia-se no modelo dos big five e são identificadas algumas das suas características, como a falta de empatia, escrúpulos, incapacidade de controlar emoções, confiança e capacidade de inovar o seu modus operandi (Sánchez y Robles, 2013). Por fim, a partir das teorias de controle social, o cibercrime e os atos dos cibercriminosos têm sido estudados de forma formal, que busca encontrar estratégias de controle do Estado, segundo González (2010), ou informalmente, que busca os motivos que levam ao cometimento dos crimes. , conforme afirma López (2015), a partir do qual, ao final, são apresentadas algumas recomendações.

Perfiles de resiliencia asociados al engagement académico y al apoyo social en estudiantes universitarios / Coping profiles associated with resilience, academic engagement, and social support in university students

Resumen El objetivo de este estudio fue observar los estilos de resiliencia entre estudiantes de pregrado y explorar la forma en la que cada uno de ellos se encontraba asociado al engagement académico y a las redes de apoyo social al inicio de los estudios universitarios. La muestra correspondió a 371 estudiantes de pregrado del Caribe Colombiano evaluados a partir de un análisis estadístico de clústeres, por el método jerárquico aglomerativo. Posteriormente se clasificaron en grupos de acuerdo con sus similitudes en las 12 dimensiones de resiliencia y finalmente se compararon en términos de engagement y redes personales. Los resultados señalaron cuatro perfiles de estudiantes: (1) sujetos con baja-resiliencia, alto engagement y fuertes vínculos relacionales; (2) resilientes-en-proceso, con niveles intermedios de resiliencia, bajo engagement y redes sociales con poca cercanía; (3) resilientes-autónomos con altos puntajes de resiliencia, niveles intermedios de engagementy redes sociales débiles; y (4) resilientes-con-redes, exhibieron altos niveles de resiliencia, con alto engagement y amplias redes de apoyo. Se concluye que la mayor porción de jóvenes que comienzan la universidad muestra perfiles de baja resiliencia; sin embargo, los altos niveles de motivación por los estudios y los recursos sociales como las redes de apoyo de los compañeros son las condiciones que más permiten afrontar los obstáculos de la vida universitaria. Es importante notar que solamente el último perfil integró los elementos de alta resiliencia, alto engagement y fuertes redes de apoyo que permiten confirmar la íntima asociación entre estos constructos. Los otros perfiles representan casos en los cuales los rasgos de resiliencia son independientes de los niveles de engagement y de la composición de las redes de apoyo personal.

Abstract Adjustment of first-year students to university environments, as well as their academic success, is not exclusively related to their academic aptitude; instead, this adjustment is associated with psychological characteristics, personal and even social resources that help students cope with stressors and new circumstances. A comprehensive assessment of the students' adjustment to university environment must transcend preoccupation on academic performance, and instead explore associations among psychological, academic, and social elements that promote adaptation during the initial years of higher education (Marenco-Escuderos et al., 2021). In this line of research, the objective of this work was to inquire how internal characteristics of students (psychological and academic) interplay with external elements in their support systems to promote adaptation in a higher education environment. Associations were explored among resilience, academic engagement, and social support as determining elements in the adjustment to the demands of the university context. The sample consisted of 371 undergraduate students (60 % female), of low socioeconomic status, enrolled in public universities in the Caribbean region of Colombia. Firstly, the resilience of university students was explored, as the ability to respond to obstacles with a positive view of the world, of others, and of one's own abilities to cope with stressors (Saavedra-Guajardo et al., 2019). Second, the level of engagement that drives young students to concentrate their energies on academic activities was reviewed; and third, the role of peers, and friends as the close-support system that facilitates the overcoming of personal and academic difficulties was investigated (Fernández-Martínez et al., 2017). Based on a statistical cluster analysis, by the agglomerative hierarchical method, individuals were classified according to their similarities in the expression of 12 dimensions of resilience (SV-RES scale), and subsequently compared in terms of engagement (UWES-S scale), and personal support networks (UNICET software). The results showed four student profiles: (1) the largest group consisting of students with low-resilience, high engagement and strong support networks; (2) a resilient group with low levels of engagement and support networks with little intimacy; (3) a resilient group with high characteristics of autonomy, intermediate levels of engagement, and support networks with weak structure; and (4) a very resilient group, high engagement, and wide and strong social support networks. The results point out the fact that the greatest proportion of students who start college show profiles of low resilience, however, high levels of motivation for studies and social resources such as peer support networks are the conditions that mostly allow for coping with adversity in the first years of college. These results could point to cultural aspects specific to the Caribbean region, where social networks are of great importance for daily functioning (Marenco-Escuderos et al., 2021). Regarding the association among the studied variables, it is important to note that only the last profile gathered all elements of high resilience, high engagement, and strong support networks that allow for confirming the association among these constructs. The other three profiles represent cases in which the resilience traits are independent of the students' levels of engagement and the composition of their personal support networks. This study is valuable as it provides a differentiating picture of the relationship of resilience with other psychological and social constructs, and in that it allows to better understand resilience in association with other elements that mediate its interpretation. Important gender differences among the profiles are additionally discussed.

Ameliorative effect of sixteen weeks endurance training on biochemical and oxidative damage in high fat diet induced obese rats

Obesity is mainly caused by consumption of high fat diet (HFD) and a lack of physical activity. Physical activity is an efficient strategy to delay development of obesity. In this studyv we tried to evaluate attenuating properties of 16 weeks endurance training on plasma oxidative stress and some biochemical parameters in HFD induced obese rats. Twenty-four male Wistar rats were randomly divided into four groups: standard diet group (SD), standard diet with endurance training group (ESD), HFD group and HFD with endurance training group (EHFD). After sixteen weeks, plasma was prepared and evaluated for measurement of different parameters. The results showed that HFD significantly decreased the activities of superoxide dismutase (33.58%), catalase (26.51%) and glutathione S-transferase (22.77%), while endurance training increased these enzymes activities. However, exercise ameliorated the increased malondialdehyde level and depletion of glutathione. In addition, it significantly reduced the increased levels of liver enzymes activities and lipid profiles. These findings suggest that endurance training has found to have beneficial effects against HFD-induced oxidative damage through increasing reduced antioxidants levels and inhibition of lipid peroxidation due to its antioxidant property. Thus, it can be considered an interesting strategy for the management of obesity related diseases.

Perfis comportamentais na perturbação do espetro do autismo e sua relação com o funcionamento executivo e empa tia numa dimensão ecológica1 / Behavioral profiles in autism spectrum disorder and relationship with executive functioning and empathy in an ecological dimension

RESUMO Défices na Comunicação Social e Interação Social (CSIS) e nos Padrões Restritos e Repetitivos de Comportamentos, Interesses ou Atividades (PRRCIA) em crianças com Perturbação do Espetro do Autismo (PEA) são frequentemente explicados por problemas nas funções executivas (FE) e empatia. O objetivo deste estudo foi analisar associações entre FE e empatia em 75 crianças com PEA (9,67±1,29), previamente separadas em dois grupos de acordo com a frequência de comportamentos típicos da PEA. Usando o Inventário Comportamental de Avaliação das Funções Executivas - Pais e a Escala de Avaliação da Empatia foram encontradas diferentes associações entre FE e empatia em ambos os grupos. No grupo com baixa frequência de comportamentos, as FE têm maior associação com CSIS (Grupo 1) do que os PRRCIA. O grupo com maior frequência de comportamentos e frequência mais homogênea entre os dois domínios (Grupo 2) apresentou associações mais fortes entre FE e PRRCIA e entre FE e empatia cognitiva. Comportamentos típicos do PEA foram melhor explicados pelas FE do que por empatia. A identificação de dificuldades nos processos neurocognitivos implicados nos comportamentos típicos da PEA poderá levar à maior adequação da intervenção numa perspetiva mais abrangente e, consequentemente, melhorar o funcionamento e comportamento adaptativo da criança no seu dia a dia.

ABSTRACT Deficits in Social Communication and Interaction (SCI) and Restricted and Repetitive Behaviours and Interests (RRBI) in children with Autism Spectrum Disorder (ASD) are frequently explained by problems in executive functions (EF) and empathy. The goal of these study was to analyze associations between EF and empathy in 75 children with ASD (9.67±1.29), previously separated into two groups according to the ASD behaviour frequency. Using the Behavior Rating Inventory of Executive Function for parents and the Empathy Assessment Scale, different associations between EF and empathy in both groups were found. In the group with low frequency of behaviours, EF have a greater association with the SCI (Group 1) than RBBI. The group with higher frequency of behaviours and more homogeneous frequency between the two domains (Group 2) presented stronger associations between EF and RBBI, and between EF and cognitive empathy. ASD typical behaviours were better explained by EF rather than empathy. The identification of difficulties in the neurocognitive processes involved in the typical behaviors of ASD may lead to a greater adequacy of the intervention in a broader perspective and, consequently, improve the functioning and adaptive behavior of the child in their daily lives.

Trayectos estudiantiles en contextos de masificación de la educación terciaria en Uruguay / Student journeys in contexts of massification of tertiary education in Uruguay / Viagens estudantis em contextos de massificação do ensino superior no Uruguai

Este artículo analiza el perfil de los estudiantes de trabajo social en contextos de masificación de la enseñanza universitaria en Uruguay que ha implicado un proceso progresivo de modificación en el volumen y estructura de capital social, cultural y económico del estudiantado durante los últimos treinta años. Los cuestionarios autoadministrados aplicados a una muestra representativa de estudiantes de la Licenciatura en Trabajo Social en los años 2013, 2016, 2018 y 2021 parecerían indicar que esta transformación del perfil de los cursantes estaría relacionada con el proceso de universalización de la educación superior pública en el país que ha implicado el ingreso de sectores sociales que, durante la mayor parte del siglo XX no accedían a la universidad. Esta buena noticia tiene su contracara en el proceso de masificación de algunas de las formaciones de grado que ofrece la Universidad de la República sin correlato de aumento de recursos para hacer frente a la sobredemanda. La enseñanza virtual incrementó aún más el proceso de masificación dado que los estudiantes tuvieron la posibilidad de cursar y ser evaluados sin cambiar su lugar de residencia. Por otra parte, este aumento de estudiantes estuvo acompañado de un incremento del estrés y el agotamiento docente para ofrecer una enseñanza de calidad mediante la incorporación de nuevos recursos tecnológicos que no todos manejaban con solvencia

This article analyzes the profile of social work students in contexts of massification of university education in Uruguay, which has implied a progressive process of modification in the volume and structure of social, cultural, and economic capital of students during the last thirty years. The self-administered questionnaires applied to a representative sample of students of Social Work Bachelor's Degree in 2013, 2016, 2018, and 2021 would seem to indicate that this transformation would be related to the process of universalization of public higher education in the country that has involved the entry of social sectors that, during most of the twentieth century, did not have access to university. This good news has its counterpart in the massification of some of the undergraduate courses offered by the University of the Republic without a corresponding increase in resources to cope with the over-demand. Virtual education further increased the process of massification, given that students were able to study and be evaluated without changing their place of residence. On the other hand, this increase in the number of students was accompanied by an increase in stress and teacher exhaustion to off er quality teaching through incorporating new technological resources that not all of them could handle with solvency

Este artigo analisa o perfil dos estudantes de Serviço Social em contextos de superlotação do ensino universitário no Uruguai, que tem envolvido um processo progressivo de modificação no volume e na estrutura do capital social, cultural e econômico do corpo estudantil ao longo dos últimos 30 anos. A autoadministração de questionários aplicados a uma amostra representativa de alunos do Bacharelado em Serviço Social nos anos de 2013, 2016, 2018 e 2021 parece indicar que essa transformação do perfil dos alunos estaria relacionada ao processo de universalização do ensino superior público no país que implicou o ingresso de setores sociais que, durante a maior parte do século XX, não teve acesso à universidade. Essa boa notícia tem seu lado negativo no processo de massificação de alguns dos cursos de graduação oferecidos pela Universidade da República sem correlato de aumento de recursos para atender o excesso de demanda. O ensino virtual aumentou ainda mais o processo de massificação, pois os alunos tiveram a oportunidade de estudar e serem avaliados sem mudar de local de residência. Por outro lado, esse aumento de alunos foi acompanhado por mais estresse e esgotamento dos professores para oferecer um ensino de qualidade por meio da incorporação de novos recursos tecnológicos que nem todos manejavam com competência

Rastros epidêmicos nas fímbrias da dor: a memória da gripe espanhola na perspectiva da história local, Botucatu (SP), 1918 / Traces of epidemics in the fringes of pain: memory of Spanish flu from a local history perspective, Botucatu (São Paulo state), 1918

Resumo O artigo perscruta sob a perspectiva da história local de que forma a memória do sofrimento que cercou a epidemia de gripe espanhola de 1918 em Botucatu (interior paulista) foi reconvocada, tensionada e transmutada ao longo do processo histórico, produzindo representações em estratégias e práticas, e apreensões como constituintes de uma realidade social que produz sentidos. Para essa operação historiográfica, coligiram-se vestígios históricos em diversos arquivos botucatuenses, entre setembro e outubro de 2021, buscando desvelar processos históricos aglutinados e depositados entre as fibras e fímbrias sociais e que, sob afecção da temporalidade, se movimentam, se reelaboram e trazem à tona a inefável marca da gripe espanhola.

Abstract This article takes a local history perspective to scrutinize how the memory of suffering that surrounded the Spanish flu epidemic of 1918 in Botucatu, São Paulo state, has been evoked, challenged, and transmuted over time, producing representations in strategies and practices, and understandings that end up constituting a meaning-making social reality. In this historiographic endeavor, historical vestiges were brought together from a variety of the city's archives between September and October 2021 in a bid to reveal the historical processes that were accreted and deposited in the social fabric and fibers, and which, under the processes of time, were changed and reworked, bringing forth the ineffable mark of Spanish flu.

Metabolic study of trimetazidine using ultra-high performance liquid chromatography-tandem mass spectrometry

Abstract In the present study, the application of ultra-high performance liquid chromatography-tandem mass spectrometry allowed us to study of known-as well as hitherto unknown-trimetazidine (TMZ) metabolites in human urine and to propose their renal excretion profiles. Urine samples from a healthy volunteer were analyzed at baseline and at 0-4 h, 4-8 h, 8-12 h, and 12-24 h after a single dose of TMZ. A dilute-and-shoot procedure was used as sample treatment before separation. Full-scan spectra of possible metabolites were acquired. Additionally, product ion scan spectra of precursor ions of interest were also acquired at two collision energies. Intact TMZ was a major excretion product, with a maximum concentration at 4-8 h after administration. Moreover, five minor metabolites were observed, namely trimetazidine-N-oxide (M1), N-formyl trimetazidine (M2), desmethyl-trimetazidine O-sulfate (M3), desmethyl-trimetazidine O-glucuronide (M4), and desmethyl-trimetazidine-N-oxide-O-glucuronide (M5). Metabolite M5 has not previously been reported. Excretion curves were constructed based on the chromatographic peak areas of specific mass transitions (precursor ion > product ion) related to each of the detected metabolites

Analyzing the evolution of insect TMED gene and the expression pattern of silkworm TMED gene / 生物工程学报

Transmembrane emp24 domain (TMED) gene is closely related to immune response, signal transduction, growth and disease development in mammals. However, only the Drosophila TMED gene has been reported on insects. We identified the TMED family genes of silkworm, Tribolium castaneum, tobacco moth and Italian bee from their genomes, and found that the TMED family gene composition patterns of one α-class, one β-class, one δ-class and several γ-classes arose in the common ancestor of pre-divergent Hymenoptera insects, while the composition of Drosophila TMED family members has evolved in a unique pattern. Insect TMED family γ-class genes have evolved rapidly, diverging into three separate subclasses, TMED6-like, TMED5-like and TMED3-like. The TMED5-like gene was lost in Hymenoptera, duplicated in the ancestors of Lepidoptera and duplicated in Drosophila. Insect TMED protein not only has typical structural characteristics of TMED, but also has obvious signal peptide. There are seven TMED genes in silkworm, distributed in six chromosomes. One of seven is single exon and others are multi-exons. The complete open reading frame (ORF) sequences of seven TMED genes of silkworm were cloned from larval tissues and registered in GenBank database. BmTMED1, BmTMED2 and BmTMED6 were expressed in all stages and tissues of the silkworm, and all genes were expressed in the 4th and 5th instar and silk gland of the silkworm. The present study revealed the composition pattern of TMED family members, their γ class differentiation and their evolutionary history, providing a basis for further studies on TMED genes in silkworm and other insects.

Identification of heat shock protein hsp70 family genes from Rana amurensis and its expression profiles upon infection / 生物工程学报

Heat shock proteins (HSPs) widely exist in all organisms, the structures of which are usually extraordinarily conservative. They are also well-known stress proteins that are involved in response to physical, chemical and biological stresses. HSP70 is an important member of the HSPs family. In order to study the roles of amphibians HSP70 during infection, the cDNA sequence of Rana amurensis hsp70 family genes were cloned by homologous cloning method. The sequence characteristics, three-dimensional structure and genetic relationship of Ra-hsp70s were analyzed by bioinformatics methods. The expression profiles under bacterial infection were also analyzed by real-time quantitative PCR (qRT-PCR). Expression and localization of HSP70 protein were tested by immunohistochemical techniques. The results showed that three conservative tag sequences of HSP70 family, HSPA5, HSPA8 and HSPA13, were found in HSP70. Phylogenetic tree analysis indicated four members are distributed in four different branches, and members with the same subcellular localization motif are distributed in the same branch. The relative expression levels of the mRNA of four members were all significantly upregulated (P < 0.01) upon infection, but the time for up-regulating the expression levels were diverse in different tissues. The immunohistochemical analysis showed that HSP70 was expressed to different degrees in the cytoplasm of liver, kidney, skin and stomach tissue. The four members of Ra-hsp70 family have ability to respond bacterial infection to varying degrees. Therefore, it was proposed that they are involved in biological processes against pathogen and play different biological functions. The study provides a theoretical basis for functional studies of HSP70 gene in amphibians.

Genome-wide DNA methylation and transcriptome expression profiles of peripheral blood mononuclear cells in patients with systemic sclerosis with interstitial lung disease / 中南大学学报(医学版)

OBJECTIVES@#This study aims to investigate the genome-wide DNA methylation and transcriptome expression profiles of peripheral blood mononuclear cells (PBMCs) in patients with systemic sclerosis (SSc) with interstitial lung disease (ILD), and to analyze the effects of DNA methylation on Wnt/β-catenin and chemokine signaling pathways.@*METHODS@#PBMCs were collected from 19 patients with SSc (SSc group) and 18 healthy persons (control group). Among SSc patients, there were 10 patients with ILD (SSc with ILD subgroup) and 9 patients without ILD (SSc without ILD subgroup). The genome-wide DNA methylation and gene expression level were analyzed by using Illumina 450K methylation chip and Illumina HT-12 v4.0 gene expression profiling chip. The effect of DNA methylation on Wnt/β-catenin and chemokine signal pathways was investigated.@*RESULTS@#Genome-wide DNA methylation analysis identified 71 hypermethylated CpG sites and 98 hypomethylated CpG sites in the SSc with ILD subgroup compared with the SSc without ILD subgroup. Transcriptome analysis distinguished 164 upregulated genes and 191 downregulated genes in the SSc with ILD subgroup as compared with the SSc without ILD subgroup. In PBMCs of the SSc group, 35 genes in Wnt/β-catenin signaling pathway were hypomethylated, while frizzled-1 (FZD1), mitogen-activated protein kinase 9 (MAPK9), mothers against DPP homolog 2 (SMAD2), transcription factor 7-like 2 (TCF7L2), and wingless-type MMTV integration site family, member 5B (WNT5B) mRNA expressions were upregulated as compared with the control group (all P<0.05). Compared with the SSc without ILD subgroup, the mRNA expressions of dickkopf homolog 2 (DKK2), FZD1, MAPK9 were upregulated in the SSc with ILD subgroup, but the differences were not statistically significant (all P>0.05). In PBMCs of the SSc group, 38 genes in chemokine signaling pathway were hypomethylated, while β-arrestin 1 (ARRB1), C-X-C motif chemokine ligand 10 (CXCL10), C-X-C motif chemokine ligand 16 (CXCL16), FGR, and neutrophil cytosolic factor 1C (NCF1C) mRNA expressions were upregulated as compared with the control group (all P<0.05). Compared with the SSc without ILD subgroup, the mRNA expressions of ARRB1, CXCL10, CXCL16 were upregulated in the SSc with ILD subgroup, but the differences were not statistically significant (all P>0.05).@*CONCLUSIONS@#There are differences in DNA methylation and transcriptome profiles between SSc with ILD and SSc without ILD. The expression levels of multiple genes in Wnt/β- catenin and chemokine signaling pathways are upregulated, which might be associatea with the pathogenesis of SSc.

Análisis cualitativo de los perfiles de egreso en procesos de aseguramiento de la calidad de carreras de Nutrición y Dietética en Chile

Método de algoritmo de clúster para el análisis del perfil de investigadores científicos

El aumento de la producción científica convierte en un desafío la tarea de identificar patrones y rasgos particulares que caractericen a los investigadores. Lograr establecer niveles de compatibilidad y similaridad entre actores en un contexto de investigación científica a partir de sus perfiles requiere de un proceso rápido y apropiado. El objetivo de este artículo es evaluar los niveles de similaridad, distancia euclidiana y compatibilidad entre vectores de investigadores, a partir de algoritmos de agrupamiento, escalamiento multidimensional, principios del modelo espacio-vectorial y atributos de sus perfiles científicos, considerando las terminologías que se abordan en su producción científica. Se utilizaron métodos teóricos y empíricos, incluyendo técnicas y herramientas de minería de texto. La aplicación del procedimiento en el Centro de Estudios de la Energía y Tecnología Avanzada de Cuba (CEETAM) y la Universidad Técnica de Cotopaxi (UTC) en Ecuador, evidenció su efectividad. Como resultado se pudo identificar los profesionales con mayores niveles de coincidencia en áreas a fines y líneas de investigación, lo que propicia el establecimiento de Comunidades Colectivas de Conocimientos; se pudo demostrar que los métodos empleados pueden ser integrados a las TIC, resultando en la obtención de relaciones perceptuales entre los investigadores y expresando los grupos que se forman a partir de conglomerados de observaciones en cada subcategoría y dominios de conocimientos de los dos casos de estudio analizados.

The increase in scientific production makes it a challenge to identify particular patterns and traits that characterize researchers. Establishing levels of compatibility and similarity between actors in a scientific research context from their profiles requires a rapid and appropriate process. The objective of this article is to evaluate the levels of similarity, Euclidean distance and compatibility between vectors of researchers, based on clustering algorithms, multidimensional scaling, principles of the vector-space model and attributes of their scientific profiles, considering the terminologies addressed in their scientific production. Theoretical and empirical methods were used, including text mining techniques and tools. The application of the procedure in the Advanced Energy and Technology Study Center from Cuba and the Cotopaxi Technical University from Ecuador, evidenced its effectiveness. As a result, it was possible to identify professionals with higher levels of coincidence in areas and lines of research, which favors the establishment of Collective Communities of Knowledge; it was possible to demonstrate that the methods used can be integrated to ICT, resulting in obtaining perceptual relationships between researchers and expressing the groups formed from clusters of observations in each subcategory and knowledge domains of the two case studies analyzed.

Clinico-Pathological Profiles of patients with Dengue Fever in Dhaka, Bangladesh

Background: Dengue viral infections are among the most important mosquito-borne diseases of the Bangladeshi subcontinent and have become a major global public health concern. The spread of the disease has led to increased recognition of atypical manifestations apart from the classical clinical features of dengue infection.This study aimed to provide clinical and biochemical profiles of Bangladesh’s dengue-infected patients.Material & Methods:This cross-sectional study was conducted from January 2021 to December 2021 in different government and private tertiary care hospitals in Dhaka, Bangladesh.

Immunohistochemical Survey of Invasive Ductal Carcinoma of the Breast, using ER, PR, HER2 and KI-67 biomarkers, in Uyo, Nigeria

Background: Breast's Invasive Ductal Carcinoma (IDC), which is the commonest type of malignancy in females worldwide, can be characterized using immunohistochemistry in view of personalized cancer therapy. In this study, we aimed to determine the pattern of immunohistochemical profiles of IDC using oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor 2 receptor (HER2) and proliferative index (Ki-67) biomarkers in our tertiary healthcare facility in Uyo, Akwa Ibom State, Nigeria given the dearth of its data in our environment. Materials and methods: We carried out a retrospective hospital-based immunohistochemical study of archival IDC tissue blocks over a four- and half-year period. Using systematic random sampling method, 64 formalin fixed paraffin embedded (FFPE) IDC tissue blocks were selected for this study. We carried out immunohistochemical evaluation using ER, PR, HER2 and Ki-67 biomarkers. Subsequently, we presented the results and classification schemes as text, tables, graphs, and photomicrographs. Results: We found that the proportion of expressions were ER-negative (88.7%), PR-negative (87.3%), HER2-negative (68.3%) and Ki-67 (<20%) being 83.6% respectively. The immunohistochemical-based classification which was done using combined immunohistochemical profiles of ER/PR/HER2 and ER/PR/HER2/Ki-67 biomarkers respectively, revealed five immunohistochemical-based subtypes. These subtypes were ER-positive luminal A (ER+/±PR+/HER2-) [5.56%], ER-positive luminal B (ER+/±PR+/HER2+) [5.56%], HER2-overexpression (ER-/±PR+/HER2+) [16.66%], Triple negative (ER-/PR-/HER2-) [66.67%] and Unclassified subtypes (ER-/PR+/HER2-) [5.56%]. Furthermore, these five subtypes were further subcategorized into low (Ki-67 <20%) and high (Ki-67 ≥20%) proliferation subtypes accordingly. Conclusion: The commonest pattern of immunohistochemical profile expression of IDC in Uyo was found to be the Triple negative subtype.

An integrated strategy for comprehensive characterization of metabolites and metabolic profiles of bufadienolides from Venenum Bufonis in rats / 药物分析学报

Comprehensive characterization of metabolites and metabolic profiles in plasma has considerable sig-nificance in determining the efficacy and safety of traditional Chinese medicine(TCM)in vivo.However,this process is usually hindered by the insufficient characteristic fragments of metabolites,ubiquitous matrix interference,and complicated screening and identification procedures for metabolites.In this study,an effective strategy was established to systematically characterize the metabolites,deduce the metabolic pathways,and describe the metabolic profiles of bufadienolides isolated from Venenum Bufonis in vivo.The strategy was divided into five steps.First,the blank and test plasma samples were injected into an ultra-high performance liquid chromatography/linear trap quadrupole-orbitrap-mass spectrometry(MS)system in the full scan mode continuously five times to screen for valid matrix compounds and metabolites.Second,an extension-mass defect filter model was established to obtain the targeted precursor ions of the list of bufadienolide metabolites,which reduced approximately 39％of the interfering ions.Third,an acquisition model was developed and used to trigger more tandem MS(MS/MS)fragments of precursor ions based on the targeted ion list.The acquisition mode enhanced the acquisition capability by approximately four times than that of the regular data-dependent acquisition mode.Fourth,the acquired data were imported into Compound Discoverer software for identification of metabolites with metabolic network prediction.The main in vivo metabolic pathways of bufadienolides were elucidated.A total of 147 metabolites were characterized,and the main biotransformation reactions of bufadienolides were hydroxylation,dihydroxylation,and isomerization.Finally,the main prototype bufadienolides in plasma at different time points were determined using LC-MS/MS,and the metabolic profiles were clearly identified.This strategy could be widely used to elucidate the metabolic profiles of TCM preparations or Chinese patent medicines in vivo and provide critical data for rational drug use.

An optical parameter imaging system with profile information fusion / 生物医学工程学杂志

There is a shared problem in current optical imaging technologies of how to obtain the optical parameters of biological tissues with complex profiles. In this work, an imaging system for obtaining the optical parameters of biological tissues with complex profile was presented. Firstly, Fourier transformation profilometry was used for obtaining the profile information of biological tissues, and then the difference of incident light intensity at different positions on biological tissue surface was corrected with the laws of illumination, and lastly the optical parameters of biological tissues were achieved with the spatial frequency domain imaging technique. Experimental results indicated the proposed imaging system could obtain the profile information and the optical parameters of biological tissues accurately and quickly. For the slab phantoms with height variation less than 30 mm and angle variation less than 40º, the maximum relative errors of the profile uncorrected optical parameters were 46.27% and 72.18%, while the maximum relative errors of the profile corrected optical parameters were 6.89% and 10.26%. Imaging experiments of a face-like phantom and a human's prefrontal lobe were performed respectively, which demonstrated the proposed imaging system possesses clinical application value for the achievement of the optical parameters of biological tissues with complex profiles. Besides, the proposed profile corrected method can be used to combine with the current optical imaging technologies to reduce the influence of the profile information of biological tissues on imaging quality.

Comprehensive Evaluation and Application of Experimental Sources of Variation in Gut Microbiome Sequencing Studies / 中国生物化学与分子生物学报

Gut microbiome sequencing studies have great potential to translate microbial analysis outcomes into human health research. Sequencing strategies of 16S amplicon and whole-metagenome shotgun (WMS) are two main methods in microbiome research with respective advantages. However, how sample heterogeneity, sequencers and library preparation protocols affect the sequencing reproducibility of gut microbiome needs further investigation. This study aims to provide a reference for the selection of sequencing technologies by comparing differences in microbial composition from different sampling sites. The results of three widely adopted sequencers showed that the technical repetition correlation (r= 0. 94) was high in WMS method, while the biological repetition correlation (r = 0. 69) was low. Bray-Curtis distance identified that dissimilarity from biological replicates was larger than that of technical replicates (P<0. 001). In addition, dissimilarity and specific taxonomic profiles were observed between 16S and WMS datasets. Our results imply that homogenization is a necessary step before sample DNA extraction. The sequencers contributed less to taxonomic variation than the library preparation protocols. We developed an empirical Bayes approach that " borrowed information" in calculations and analyzed batch effect parameters using standardized data and prior distributions of (non-) parameters, which may improve population comparability between 16S and WMS and provide a basis for further application to fusion analysis of published 16S and microbial datasets.
