Prediction of soil seed bank of piedmont and alluvial environments of Dera Ghazi Khan, Punjab, Pakistan / Predição do banco de sementes do solo do piemonte e ambientes aluviais de Dera Ghazi Khan, Punjab, Paquistão

Abstract The current focus is on the overall pattern of seed storage present in the fragments of the soil of piedmont and alluvial landscapes of the environment. The present study predicted the seed banks of both soils of alluvial and piedmont zones in different ecological conditions and evaluate the potential of seeds in the restoration of both environments. The composition of the seed bank of soil is mainly affected by the alluvial environment and the structure of cleared area shows that more species of germinating annual grasses and growable seeds with the higher total number. Extant vegetation structures have an important role in the diversity of soil seed reservoirs, whose composition corresponded with the openness of the site. When in situ soil seed bank is recruited, it helps to restore only some components of the plant community in an alluvial environment. In our current research, it was confirmed that seed richness was higher in number at lower elevation (alluvial) than that at high elevation (piedmont). Seed richness showed a significant negative correlation with anions, cations, while significantly positive with altitude that suggests the richness pattern of the overall seed bank of the area is influenced by various environmental factors.

Resumo O foco atual está no padrão geral de armazenamento de sementes presente nos fragmentos de solo do Piemonte e nas paisagens aluviais do meio ambiente. O presente estudo previu os bancos de sementes de ambos os solos das zonas aluvial e piemontesa em diferentes condições ecológicas e avaliou o potencial das sementes na restauração de ambos os ambientes. A composição do banco de sementes do solo é afetada principalmente pelo ambiente aluvial e a estrutura da área desmatada mostra que mais espécies de gramíneas anuais em germinação e sementes cultiváveis ​​apresentam o maior número total. As estruturas da vegetação existente têm um papel importante na diversidade dos reservatórios de sementes do solo, cuja composição correspondeu à abertura do local. Quando o banco de sementes do solo in situ é recrutado, o mesmo ajuda a restaurar apenas alguns componentes da comunidade de plantas em um ambiente aluvial. Em nossa pesquisa atual, foi confirmado que a riqueza de sementes era maior em número em altitudes mais baixas (aluviais) do que em altitudes elevadas (Piemonte). A riqueza de sementes mostrou uma correlação negativa significativa com ânions, cátions, enquanto significativamente positiva com a altitude, o que sugere que o padrão de riqueza do banco geral de sementes da área é influenciado por vários fatores ambientais.

Rational drug repurposing for alzheimer's treatment using in-silico ligand and structure-based approaches

Abstract Alzheimer's disease is a devastating neurodegenerative disorder characterized by memory loss and cognitive decline. New AD treatments are essential, and drug repositioning is a promising approach. In this study, we combined ligand-based and structure-based approaches to identify potential candidates among FDA-approved drugs for AD treatment. We used the human acetylcholinesterase receptor structure (PDB ID: 4EY7) and applied Rapid Overlay of Chemical Structures and Swiss Similarity for ligand-based screening.Computational shape-based screening revealed 20 out of 760 FDA approved drugs with promising structural similarity to Donepezil, an AD treatment AChE inhibitor and query molecule. The screened hits were further analyzed using docking analysis with Autodock Vina and Schrodinger glide. Predicted binding affinities of hits to AChE receptor guided prioritization of potential drug candidates. Doxazosin, Oxypertine, Cyclopenthiazide, Mestranol, and Terazosin exhibited favorable properties in shape similarity, docking energy, and molecular dynamics stability.Molecular dynamics simulations confirmed the stability of the complexes over 100 ns. Binding free energy analysis using MM-GBSA indicated favourable binding energies for the selected drugs. ADME, formulation studies offered insights into therapeutic applications and predicted toxicity.This comprehensive computational approach identified potential FDA-approved drugs (especially Doxazosin) as candidates for repurposing in AD treatment, warranting further investigation and clinical assessment.

Design thinking como metodologia na elaboração de uma proposta de matriz curricular / Design thinking as a methodology in the elaboration of a curricular structure proposal

Resumo Introdução: A matriz curricular do curso de Medicina pode variar de acordo com o projeto pedagógico de curso (PPC) de cada instituição de ensino superior (IES). Nem sempre a visão da coordenação e do corpo docente do curso de Medicina está alinhada às opiniões dos alunos. Assim, a utilização de uma metodologia para identificar a visão do corpo discente seria fundamental. O design thinking (DT) é um processo que propõe a busca, de forma empática, colaborativa e criativa, de soluções para problemas complexos. Objetivo: Este estudo apresenta o DT como uma metodologia para identificar como os alunos do internato acreditam que deva ser a matriz curricular do primeiro ao quarto ano de um curso de Medicina no estado de São Paulo, e, para tanto, coletaram-se sugestões e pontos que exigiram a reavaliação na matriz original. Método: Realizou-se uma avaliação qualitativa com base no modelo do DT. Os alunos foram divididos em três grupos de cinco alunos, e cada grupo dedicou-se a discutir livremente sobre suas ideias acerca da matriz curricular. Posteriormente, apresentou-se um painel para cada grupo com a separação dos semestres correspondentes - do primeiro ao quarto ano - com post-it representando a matriz curricular vigente do curso de Medicina, e cada grupo teve uma hora para remontar a matriz curricular da maneira que julgasse mais adequado. Resultado: Após a fase de discussão, cada grupo montou sua matriz curricular, e propuseram-se algumas mudanças do ano em que a disciplina era ministrada e a inclusão de algumas matérias. A maioria das sugestões foi julgada procedente e incorporada na matriz curricular. Conclusão: A metodologia do DT contribuiu para a identificação de várias demandas acerca da matriz curricular de uma forma ordenada, empática e colaborativa, levando em consideração a opinião do estudante, sendo, portanto, uma estratégia de planejamento capaz de evidenciar fragilidades e fortalezas do currículo que talvez não fossem percebidas por outras estratégias.

Abstract Introduction: The medical school curricular structure may vary according to the educational planning of each higher education institution (HEI). The viewpoint of the coordination and the medical school faculty is not always aligned with the students' opinions. Thus, using a methodology to identify the students' point of view would be essential. Design thinking (DT) is a process that proposes a search, in an empathetic, collaborative, and creative way, for solutions to complex problems. Objectives: To present DT as a methodology to identify how clinical internship students believe the curricular structure from the 1st to the 4th year of a São Paulo state medical school should be, by collecting suggestions and points that require a re-evaluation process of the current curricular structure. Methods: This is a qualitative assessment, which will use the DT model. Students were divided into three groups of five, and each group was committed to having a free discussion on its ideas concerning the curricular structure. Then, a panel was presented to each group, dividing the semesters from the 1st to the 4th year with post-it notes representing the current curricular structure of the medical school, and each group had one hour to reassemble the curricular structure as they deemed appropriate. Results: After the discussion stage, each group assembled its curricular structure. Some changes concerning the year in which the discipline was provided were proposed, and the inclusion of others. Most of the suggestions were considered valid and were incorporated into the curriculum. Conclusions: The DT methodology contributed to the identification of several demands regarding the curricular structure in an orderly, empathetic, and collaborative way, taking into account the students' opinions. It is, therefore, a planning strategy able to evidence weaknesses and strengths of the curriculum that might not have been noticed by the use of other strategies.

Effect of electrochemically dealloying Ti6Al4V abutments on human gingival fibroblasts / 口腔疾病防治

Objective@#To investigate the effects of electrochemically dealloying of Ti6Al4V abutments on human gingival fibroblasts (HGFs) and to provide experimental evidence for surface modification of implant abutments.@*Methods@#The samples were divided into an NC group (negative control, no other treatment on a smooth surface), an NM-1 group (nanomesh-1, electrochemical dealloying treatment in 1 mol/L NaOH 1 h on 2 V voltage), and an NM-2 group (nanomesh-2, electrochemical dealloying treatment in 5 mol/L NaOH 1 h on 2 V voltage). The surface morphologies of the samples and the adhesion of HGFs on the sample surfaces were observed with scanning electron microscopy (SEM). The surface hydrophilicities of the samples were measured with a contact angle measuring instrument. The proliferation of HGFs on the different samples were evaluated with CCK-8, and the expression of adhesion-related genes, including collagen Ⅰ (COL1A1), collagen Ⅲ (COL3A1), fibronectin 1 (FN1), focal adhesion kinase (FAK), vinculin (VCL), integrin α2 (ITGA2), and integrin β1 (ITGB1), on the different samples was measured with qRT-PCR. The expression of vinculin on the surfaces of HGFs was observed via confocal laser scanning microscopy (CLSM) after immunofluorescent staining. Collagen fiber secretion and syntheses of HGFs from different samples were evaluated via Sirius red staining.@*Results@#SEM revealed the formation of ordered and uniform three-dimensional mesh structures on the surfaces of the NM-1 and NM-2 groups, with grid diameters of approximately 30 nm for the NM-1 group and approximately 150 nm for the NM-2 group. Compared with that of the NC group, the water contact angles of the NM-1 group and NM-2 groups were significantly lower (P<0.000 1). Cell proliferation in the NM-1 group was significantly greater than that in the NC group (P<0.01). Moreover, there was no significant difference in the water contact angles or cell proliferation between the NM-1 group and the NM-2 group. SEM revealed that HGFs were adhered well to the surfaces of all samples, while the HGFs in the NM-1 and NM-2 groups showed more extended areas, longer morphologies, and more developed pseudopodia than did those in the NC group after 24 h. qRT-PCR revealed that the expression levels of the adhesion-related genes COL1A1, COL3A1, FN1, FAK and VCL in the NM-1 group were significantly greater than those in the NC and NM-2 groups (P<0.01). The expression of vinculin protein in the NM-1 group was the highest, and the number of focal adhesions was greatest in the NM-1 group (P<0.01). The results of Sirius red staining showed that the NM-1 group had the highest secretion and syntheses of collagen fibers (P<0.000 1).@*Conclusion@#The three-dimensional nanomechanical structure of Ti6Al4V modified by electrochemical dealloying promoted the adhesion, proliferation, collagen fiber secretion and syntheses of HGFs, and electrochemical dealloying of Ti6Al4V with a grid diameter of approximately 30 nm obviously promoted HGF formation.

Research progress on herpes simplex virus membrane fusion protein interactions / 中国生物制品学杂志

@#Herpes simplex virus(HSV)is a ubiquitous enveloped virus containing double-stranded DNA. HSV-1 infection can cause inflammation of the lips,conjunctivitis and encephalitis,HSV-2 infection can cause genital herpes at many ages,and both viruses can establish lifelong latent infection in the body. Membrane fusion triggered by the interaction of various HSV membrane proteins is an important way for viruses to enter host cells. This review introduced the conserved core fusion mechanism of HSV composed of four viral glycoproteins gD,gH,gL and gB by analyzing the structure of glycoproteins and their interaction modes. Since there is currently no HSV vaccine approved for marketing in the world,it is of great significance to study the mode of action of HSV and host cells for the development of vaccines

Development and prospects of predicting drug polymorphs technology / 药学学报

Most chemical medicines have polymorphs. The difference of medicine polymorphs in physicochemical properties directly affects the stability, efficacy, and safety of solid medicine products. Polymorphs is incomparably important to pharmaceutical chemistry, manufacturing, and control. Meantime polymorphs is a key factor for the quality of high-end drug and formulations. Polymorph prediction technology can effectively guide screening of trial experiments, and reduce the risk of missing stable crystal form in the traditional experiment. Polymorph prediction technology was firstly based on theoretical calculations such as quantum mechanics and computational chemistry, and then was developed by the key technology of machine learning using the artificial intelligence. Nowadays, the popular trend is to combine the advantages of theoretical calculation and machine learning to jointly predict crystal structure. Recently, predicting medicine polymorphs has still been a challenging problem. It is expected to learn from and integrate existing technologies to predict medicine polymorphs more accurately and efficiently.

Strengths and Difficulties Questionnaire (SDQ): An update of the literature and instrumental study with schoolchildren

Introduction: Considering the current controversy regarding the factorial structure of the SDQ, this paper aimed to analyse the dimensionality and reliability of the parents' version for children from 4 to 16 years of age, and to present descriptive data according to sociodemographic variables. Method: The factor structure of the original five- and three-factor models, and the reliability of the SDQ were examined among a sample of 621 parents of Uruguayan children between 7 and 12 years of age (52% girls) from different socioeconomic levels. Results: Confirmatory factor analyses did not provide support for the five- and three-factor models. Data adjusted to three factors (prosociality, externalising symptoms, internalising symptoms) in an exploratory analysis with adequate reliability indices. Conclusions: The results of this study show the relevance of continued investigation of the SDQ internal structure, and further analysis of the behaviour of several of its items.

Introducción: Considerando la controversia vigente respecto a la estructura factorial del SDQ, este trabajo tuvo como objetivo analizar la validez de constructo y fiabilidad de la versión para padres de niños de 4 a 16 años y presentar datos descriptivos según variables sociodemográficas. Método: Se examinó la estructura factorial de los modelos originales de cinco y tres factores y la fiabilidad del SDQ en una muestra de 621 padres de niños uruguayos entre 7 y 12 años (52 % niñas) de distintos niveles socioeconómicos. Resultados: Los análisis factoriales confirmatorios no pudieron dar apoyo a los modelos de cinco y tres factores. Los datos se ajustaron a tres factores (prosocialidad, síntomas externalizantes y síntomas internalizantes) en un análisis exploratorio con adecuados índices de fiabilidad. Conclusiones: Los resultados de este estudio muestran la pertinencia de continuar investigando la estructura interna del SDQ y analizar con mayor profundidad el comportamiento de algunos de sus ítems.

Variabilidad de comunidades de macroinvertebrados acuáticos en charcas temporales del norte de Colombia

Introducción: Las charcas temporales son ecosistemas acuáticos variables en su estructura física y biótica, efímeros en el paisaje e importantes en el flujo de materia y energía. Los macroinvertebrados acuáticos constituyen el grupo más abundante y diverso en estos ecosistemas y requieren mayor estudio, particularmente en los trópicos. Objetivo: Evaluar la diversidad alfa y beta de las comunidades de macroinvertebrados acuáticos de seis charcas temporales durante dos épocas climáticas en el norte de Colombia. Métodos: En Magdalena, Colombia, hicimos seis arrastres aleatorios con redes manuales en la zona litoral, y seis arrastres en zigzag con redes tipo D en la zona lacustre; recolectamos macrofauna en tres lances con una draga Ekman; y muestreamos cada charca durante la alta precipitación (noviembre, 2020) y la baja precipitación (febrero, 2021). Resultados: Identificamos 3 358 individuos (13 órdenes, 39 familias y 68 géneros). La mayor abundancia y diversidad (N= 485, 0D= 32) durante la época de lluvia se presentó en Los Campanos, mientras que la charca Villa Leidy tuvo el mayor número de taxones comunes (18) y dominantes (14). En la época de sequía, la charca Los Trillizos presentó la mayor abundancia (533) y diversidad (43); mientras que Villa Leidy y El Miquito el mayor número de taxones dominantes (16). Las charcas tienen composiciones particulares (sin agrupamientos espaciales o temporales); el recambio de taxones es alto, y la correspondencia canónica se agrupa por temporada. Conclusiones: la composición de las comunidades de macroinvertebrados acuáticos de las charcas temporales son muy diversas, presentando alto recambio tanto espacial como temporal, reflejando altos valores de remplazo de taxones entre épocas climáticas. La zona litoral mantuvo una composición similar durante las dos temporadas.

Introduction: Temporary ponds are variable aquatic ecosystems in their physical and biotic structure, ephemeral in the landscape and important in the flow of matter and energy. Aquatic macroinvertebrates constitute the most abundant and diverse group in these ecosystems and need further study, particularly in the tropics. Objective: To evaluate the alpha and beta diversity of the aquatic macroinvertebrate communities of six temporary pools during two climatic seasons in Northern Colombia. Methods: In Magdalena, Colombia, we did six random trawls with hand nets in the coastal zone, and six zig zag trawls with D nets in the lacustrine zone; we collected macrofauna in three random hauls with an Ekman dredge; and sampled each pond in high rainfall (November 2020) and low rainfall (February 2021). Results: We identified 3 358 individuals (13 orders, 39 families and 68 genera). The highest rainy season abundance and diversity (N= 485, 0D= 32) were in Los Campanos, while Villa Leidy Pond had the highest number of common (18) and dominant (14) taxa. During the dry season, Los Trillizos Pond had the highest abundance (533) and diversity (43); while Villa Leidy and El Miquito had the largest number of dominant taxa (16). The pools have a particular composition (no spatial or temporal grouping); taxa turnover is high, and the canonical correspondence clustered by season. Conclusions: The aquatic macroinvertebrate communities of the temporary ponds are diverse and have high turnover in space and time, reflecting high replacement of taxa between climatic periods. The littoral zone had a similar composition in the two seasons.

The best of two worlds: Combining the DSM-5 and ICD-11 clusters of symptoms for posttraumatic stress disorder in a single screening scale

Objectives: The most recent DSM-5 (2013) and ICD-11 (2018) diagnostic criteria for posttraumatic stress disorder (PTSD) encompass 20 and six symptoms, respectively, organized in different structures. This study aimed to investigate the dimensions of the Posttraumatic Stress Disorder Checklist 5 (PCL-5) according to the DSM-5's broader definition of PTSD and the ICD-11's narrower approach, as well as to explore an alternative restricted model that retains the core symptoms explicitly related to traumatic experiences. Methods: Data were gathered from Brazilian employees (n=1,101) who had directly experienced traumatic life events or had been exposed to them because of their work activities. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to evaluate the configural and metric structures of the models. Results: We estimated seven models of the latent structure of PTSD including the four-factor DSM-5 and three-factor ICD-11 PTSD models. Given the lack of evidence of their validity, an alternative 10-symptom model was tested. The final seven-item PTSD model considerably improved estimation of the PTSD construct. This solution showed reliable items with non-redundant content, acceptable fit indices, and satisfactory configural and metric properties. Conclusion: The more parsimonious one-dimensional model comprising the core PTSD symptoms has the potential to improve assessment of PTSD.

Aspectos estruturais para a Diabetes Mellitus nas Unidades Básicas de Saúde em capitais brasileiras / Structural aspects for Diabetes Mellitus in Basic Health Units in Brazilian capitals

RESUMO Objetivou-se, neste artigo, analisar as condições estruturais de unidades de saúde e as diretrizes, os objetivos e as metas da gestão municipal relacionados com a qualidade desses serviços nas capitais segundo regiões brasileiras, tendo em vista a atenção às pessoas com Diabetes Mellitus. Para tanto, foram elaborados um modelo lógico e subdimensões/variáveis para direcionar a busca de dados no banco do Programa de Melhoria de Acesso e Qualidade da Atenção Primária à Saúde, do 3º ciclo. Análises descritivas foram realizadas das capitais por região do Brasil. Para análise documental, utilizaram-se os planos de saúde daqueles municípios que apresentaram percentual de inadequação maior que 50% para, no mínimo, quatro dimensões entre as sete analisadas neste estudo. O estudo revelou necessidade de adequação das condições estruturais das Unidades Básicas de Saúde para a maioria das capitais brasileiras em alguns dos aspectos analisados, com piores resultados para estrutura física e equipamentos. A partir da análise dos planos municipais de saúde, evidenciaram-se particularidades, potencialidades e fragilidades que merecem ser consideradas para definição da agenda e direcionamento das ações pela gestão em saúde. As condições de inadequação apontadas podem trazer impactos negativos na qualidade da atenção às pessoas com diabetes na Atenção Primária à Saúde.

ABSTRACT The objective of this article is to analyze the structural conditions of health units and the guidelines, objectives/goals of municipal management related to the quality of those services in the capitals according to Brazilian regions, aimed at caring for persons suffering from Diabetes Mellitus. For that, a logical model and sub-dimensions/variables were developed to direct the search for data in the 3rd cycle of the Program for Improving Access and Quality of Primary Health Care. Descriptive analyzes of the capitals were performed by region of Brazil. For document analysis, we used the Health Plans of municipalities that presented a percentage of inadequacy greater than 50% for at least four dimensions among the seven analyzed in this study. The study revealed the need to adapt the structural conditions of Basic Health Units for most Brazilian capitals in some of the aspects analyzed, with worse results for physical structure and equipment. Based on the analysis of municipal health plans, particularities, strengths, and weaknesses were evidenced that deserve to be considered for defining the agenda and directing actions by health management. The identified conditions of inadequacy can have a negative impact on the quality of care for persons suffering from diabetes in Primary Health Care.

Intervención educativa grupal para incrementar el ejercicio físico en personal de salud y la prescripción de este en sus pacientes / Group educational intervention to increase physical exercise in healthcare personnel and promote its prescription for their patients / Intervenção educativa em grupo para aumentar o exercício físico em profissionais de saúde e sua prescrição em seus pacientes

Objetivo: el objetivo del estudio fue evaluar el impacto de una intervención educativa grupal en el personal de salud para mejorar su práctica de ejercicio físico y la prescripción de esta a sus pacientes. Metodología: diseño preexperimental con medidas repetidas en un solo grupo, compuesto por personal de la salud (n = 17). Resultados: en el personal de salud se encontró un incremento en la motivación hacia la práctica de ejercicio físico (Likert, pre: 56 vs. 3 meses: 61). La principal motivación fue mantener un buen estado de salud, con un incremento del 18 % a los 6 meses con respecto del inicio. Sin embargo, también se identificó una reducción en el tiempo de práctica semanal de ejercicio físico, en la intensidad moderada (mediana, pre 120 minutos [75 - 210], tres meses 105 minutos [45 - 180], seis meses 60 minutos [50 - 135]) y en la vigorosa (mediana, pre 300 minutos [121,5 - 360], tres meses 60 minutos [30 - 120], seis meses 30 minutos [30 - 60]). La prescripción de ejercicio físico mejoró en frecuencia (pre 23 %, tres meses 36 %, seis meses 30 %) y componentes, además se acompañó de una reducción de los minutos/semana que el paciente la practicaba. Conclusiones: una intervención educativa grupal para el personal de salud puede influenciar de manera positiva algunos componentes actitudinales a favor de su práctica de ejercicio físico y la prescripción de este en sus pacientes, pero afecta negativamente su práctica en ambos grupos.

Objective: The aim of this study was to assess the effects of a group-based educational intervention on healthcare professionals' engagement in physical exercise and their ability to prescribe it to their patients. Methodology: This study employed a pre-experimental design with repeated measures within a single group, comprising healthcare professionals (n = 17). Results: Among healthcare professionals, an increase in motivation towards engaging in physical exercise was observed (Likert scale, pre: 56 vs. 3 months: 61). The main motivation reported was maintaining good health, which showed an 18 % increase at the 6-month mark compared to the start of the study. However, a reduction was also identified in the weekly duration of moderate-intensity exercise (median, pre: 120 minutes [75-210], three months: 105 minutes [45-180], six months: 60 minutes [50-135]), as well as vigorous-intensity exercise (median, pre: 300 minutes [121.5-360], three months: 60 minutes [30-120], six months: 30 minutes [30-60]). The prescription of physical exercise improved in terms of frequency (pre: 23 %, three months: 36 %, six months: 30 %) and components, accompanied by a reduction in the number of minutes per week that patients engaged in exercise. Conclusions: A group-based educational intervention for healthcare professionals can positively influence certain attitudinal components in favor of their engaging in physical exercise and prescribing it to their patients. However, it negatively affects their actual exercise practice in both groups.

Escala de Percepción de Reforzamiento Medioambiental (EROS): evidencias de validez en una muestra colombiana

Introducción: El objetivo de esta investigación fue confirmar la estructura interna de la Environmental Reward Observation Scale (EROS) y recoger evidencias de su relación con otros constructos en una muestra colombiana de 902 adultos que consintieron participar voluntariamente. Método: Se realizaron análisis psicométricos con Teoría Clásica de los Test y el modelo de Rasch. Se recolectaron evidencias de validez de la estructura interna y de la relación de las puntuaciones con otras variables. Resultados: Se obtuvieron buenos índices en los coeficientes alfa y omega de McDonald, nueve de los 10 ítems tuvieron buenos ajustes en los índices infit y outfit, y el ítem ocho presentó DIF en el nivel educativo. Se confirmó la estructura unidimensional de la EROS y fue invariante respecto al sexo y nivel educativo. Los puntajes tuvieron correlaciones de magnitud alta con sintomatología emocional y variables afines a la Activación Conductual. Conclusiones: La EROS presentó altas calidades psicométricas para su uso en población colombiana; sin embargo, se recomienda su uso solo para evaluación de tamizaje, porque los niveles de información están centrados en un área reducida a lo largo de la métrica logit.

Introduction: The aim of this research was to confirm the internal structure of the Environmental Reward Observation Scale (EROS) and to collect evidence of its relationship with other constructs in a Colombian sample of 902 adults who voluntarily consented to participate. Method: Psychometric analyses were performed using Classical Test Theory and the Rasch model. Evidence of validity based on internal structure and relations of scores with other variables was collected. Results: Good indexes were obtained in McDonald's Alpha and Omega coefficients, 9 of the 10 items had good adjustments in the Infit and Outfit indexes, and item 8 presented DIF in the educational level. The unidimensional structure of the EROS was confirmed and was invariant with respect to sex and educational level. Scores had high magnitude correlations with emotional symptomatology and variables related to Behavioral Activation. Conclusions: The EROS presented high psychometric qualities for its use in the Colombian population; however, its use is recommended only for screening assessment because the levels of information are centered in a reduced area along the Logit scaling.

INDIAN NATIONAL EDUCATION POLICY 2020 VISUALISATION: A SUMMARY

The National Education Policy 2020 is the rst education policy of the 21st century and aims to address the many growing developmental imperatives of our country. This Policy proposes the revision and revamping of all aspects of the education structure, including its regulation and governance, to create a new system that is aligned with the inspirational goals of 21st century education, including SDG4, while building upon India's traditions and value systems. The National Education Policy lays particular emphasis on the development of the creative potential of each individual. It is based on the principle that education must develop not only cognitive capacities - both the 'foundational capacities 'of literacy and numeracy and 'higher-order' cognitive capacities, such as critical thinking and problem solving – but also social, ethical, and emotional capacities and dispositions.

Reabilitação com prótese bucomaxilofacial: revisão de literatura / Rehabilitation with maxillofacial prosthetics

A odontologia reabilitadora tem como um dos seus ramos a especialidade de Prótese Bucomaxilofacial (PBMF), que visa restaurar ou substituir estruturas perdidas na região facial e no sistema estomatognático artificialmente, podendo ser ou não removidos pelo paciente. O presente trabalho objetiva revisar a leitura a respeito da reabilitação com PBMF e a sua aplicabilidade na clínica odontológica. Os indivíduos com alguma perda de estrutura na região de cabeça e pescoço, devido a traumas físicos e/ou químicos, defeitos congênitos, doenças autoimunes, neoplasias, infecções e parasitas, são pacientes para os quais há a indicação da reposição da parte ausente. As reconstruções podem ser perdas intraorais (área da maxila, mandíbula), extraorais (oculopalpebral, ocular, nasal, facial extensa e auricular) ou conjugadas. Esse é um trabalho multidisciplinar, com especialistas de áreas abrangentes e todos os especialistas trabalham de forma conjunta. Pode-se concluir que, embora seja uma das especialidades mais nobres da odontologia, ainda é muito desconhecida por parte dos estudantes e profissionais das áreas da saúde e são próteses absolutamente fundamentais para a reabilitação e qualidade de vida dos indivíduos que tem a necessidade do uso da prótese PBMF(AU)

Rehabilitating dentistry has as one of its branches the specialty of Oral and Maxillofacial Prosthesis (PBMF), which aims to restore or replace structures lost in the facial region and in the stomatognathic system artificially, which may or may not be removed by the patient. The present study aims to review the reading about rehabilitation with PBMF and its applicability in dental clinic. Individuals with some loss of structure in the head and neck region, due to physical and/or chemical trauma, birth defects, autoimmune diseases, neoplasms, infections and parasites, are patients in whom there is an indication for replacement of the absent part. Reconstructions can be intraoral (maximal area, mandible), extraoral (oculopalpebral, ocular, nasal, extensive facial and auricular) or conjugated losses. It is a multidisciplinary work, with specialists from the comprehensive areas and that all specialists work together. It can be concluded that although it is one of the noblest specialties of dentistry, it is still very unknown to students and health professionals, and they are absolutely fundamental prostheses for the rehabilitation and quality of life of individuals who need the use the PBMFprosthesis(AU)

Knowledge regarding reverse osmosis (R.O) waste water utilization among general public in urban areas

Introduction: Reverse osmosis (RO) is a water purification process that uses a partial permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. In the process of reverse osmosis the amount of water that is drained is a concern area for the people using the R.O. filtration device in their household because it wasted about 70% of the water to purify just one liter of water. This R.O. waste water can be utilized for various purposes such as washing vehicle like car bike etc, cleaning toilet this study is aimed to assess the knowledge reverse osmosis waste water utilization among general public at Indore. Objectives: 1. To assess the pretest knowledge regarding reverse osmosis (R.O) waste water utilization among general public. 2. To assess the posttest knowledge regarding reverse osmosis waste water utilization among general public. 3. To evaluate the effectiveness of structured teaching program on reverse osmosis (R.O) waste water utilization among general public. Hypothesis: H1- there will be significant difference between pretest and posttest knowledge who received structured teaching program regarding the utilization of waste R.O water. Materials and Methods: Quantitative, pre-experimental, one group pretest posttest design was adopted for the study. Total of 60 general public selected by using simple randomized sampling technique was used. Description of Tools: Structured knowledge questionnaire. Result: Data was analyzes using descriptive and inferential statistics. Major Finding: In the pre-test majority of the sample (44 out of 60, 73.3%) had inadequate knowledge and in the post-test, majority (54 out of 60, 90%) had adequate knowledge regarding reverse osmosis. A paired‘t’ test was done and it showed a‘t’ value of 22.34 at 0.05 level of significance, this indicates the effectiveness of structured teaching programme in enhancing the knowledge of the general public. There was no association found between the mean pre-test knowledge of the general public. There was no association found between the mean pre-test knowledge scorer with the selected socio-demographic variable such as age (?2 = 8.643), gender (?2 = 4.455), education qualification (?2 = 4.706), Occupation (?2 = 2.531), number of family member (?2 = 5.653) and previous knowledge about reverse osmosis filter water (?2 =0.393). Conclusion: There is a significant difference between the mean pre-test and post-test knowledge score among general public regarding reverse osmosis waste water utilization.

Preliminary validity for the Big Five Inventory-2 in brazilian adults / Evidências preliminares de validade do Big Five Inventory-2 em adultos brasileiros / Evidencias preliminares de validez del Big Five Inventory-2 en adultos brasileños

The Big Five Inventory-2 (BFI-2) assesses personality through the big five factor model model (FFM). This study aimed to verify whether the internal structure of the BFI-2 is corroborated in a Brazilian sample. Participants were 908 cisgender adults, aged between 17 and 93 years, 532 of whom were women. Confirmatory factor analysis and Exploratory structural equation modeling were performed with the BFI-2. The 15 facets of personality resulted in adequate fit and reliability, mainly for the respondents under 60 years of age. We conclude that the BFI-2 presents evidence of preliminary validity based on its internal structure, although further validity studies are required with the instrument, to testify its psychometric quality.

Study of developing tracheal cartilage under light microscope

Background: Airway formation is one of the earliest events in development of respiratory system. However, maturation of airway continues well in post-natal life. The trachea has framework of incomplete ring of hyaline cartilage united by fibrous tissue and smooth muscle through which air conduction takes place. The trachea-bronchial mucosa is target for host of airborne toxic agents; bacterial and viral agents, allergens, reactive gases, aerosols, and irritant particles. This fascinates many workers for detailed study of epithelium or lining air passage. Aims and Objectives: The present study was undertaken to document normal developmental microscopic structure of tracheal cartilage in fetuses of different age group (gestational ages between 12th and 40th weeks) and to compare the difference between different age groups. Materials and Methods: Tissues from trachea of various age group fetuses were collected, processed, and stained with H and E and Masson’s trichrome. Results: Development of tracheal cartilage was observed into three trimesters. The 2nd and 3rd trimesters were further divided in the early 2nd (13th–16th weeks), mid-2nd (17th–20th weeks), late 2nd (21st–24th weeks), early 3rd (25th–28th weeks), mid-3rd (29th–32nd weeks), and late 3rd (33rd–40th weeks) phases. Conclusion: Perichondrium of cartilage had shown well-marked outer fibrous layer with increased vascularity by late 2nd to early 3rd trimester. Well-marked inner cellular layer of perichondrium was noticed by 3rd trimester, while cartilage had shown active chondrocytes by late 2nd to early 3rd trimester. At the late 3rd trimester, typical hyaline cartilage had shown chondrocytes in cell nest surrounded by territorial matrix.

Relationship between posterior staphyloma and fundus structure and microcirculation in high myopia / 中华实验眼科杂志

Posterior staphyloma (PS) refers to the local abnormal bulge of the posterior wall of the eyeball, which is one of the common pathological changes in high myopia.The appearance of PS is often accompanied by changes in fundus microstructure such as sclera, choroid and Bruch membrane.The abnormality of fundus microstructure leads to the decrease of its resistance to the expansion of ocular axis, or causes the remodeling of tissue structure in the corresponding area, resulting in the change of microvascular structure, and then giving rise to abnormal blood circulation in the posterior pole.The microcirculatory changes may be followed by changes in fundus microstructure, seriously affecting the visual acuity of the affected eyes.There is still no clear conclusion on the pathogenesis of PS in the world, and there are no good preventive measures or treatment methods.This article reviewed and summarized the interaction between PS, fundus structure and microcirculation in high myopia, so as to provide a theoretical basis for exploring the pathogenesis, prevention and treatment of PS and improving the visual function of high myopia.
