Photosynthetic acclamatory response of Panicum antidotale Retz. populations to root zone desiccation stress / Reação fotossintética aclamatória de Panicum antidotale Retz. populações submetidas ao estresse da dessecação da zona radicular

Abstract Growth of plants is severely reduced due to water stress by affecting photosynthesis including photosystem II (PSII) activity and electron transport. This study emphasised on comparative and priority targeted changes in PSII activity due to progressive drought in seven populations of Panicum antidotale (P. antidotale) collected from Cholistan Desert and non-Cholistan regions. Tillers of equal growth of seven populations of P. antidotale grown in plastic pots filled with soil were subjected progressive drought by withholding water irrigation for three weeks. Progressive drought reduced the soil moisture content, leaf relative water content, photosynthetic pigments and fresh and dry biomass of shoots in all seven populations. Populations from Dingarh Fort, Dingarh Grassland and Haiderwali had higher growth than those of other populations. Cholistani populations especially in Dingarh Grassland and Haiderwali had greater ability of osmotic adjustment as reflected by osmotic potential and greater accumulation of total soluble proteins. Maximum H2O2 under water stress was observed in populations from Muzaffargarh and Khanewal but these were intermediate in MDA content. Under water stress, populations from Muzaffargarh and Dingarh Fort had greater K+ accumulation in their leaves. During progressive drought, non-Cholistani populations showed complete leaf rolling after 23 days of drought, and these populations could not withstand with more water stress condition while Cholistani populations tolerated more water stress condition for 31 days. Moreover, progressive drought caused PSII damages after 19 days and it became severe after 23 days in non-Cholistani populations of P. antidotale than in Cholistani populations.

Resumo O crescimento das plantas é severamente reduzido devido ao estresse hídrico, afetando a fotossíntese, incluindo a atividade do fotossistema II (PSII) e o transporte de elétrons. Este estudo enfatizou as mudanças comparativas e prioritárias na atividade do PSII devido à seca progressiva em sete populações de Panicum antidotale (P. antidotale) coletadas no Deserto do Cholistão e regiões fora do Cholistão. Perfilhos de igual crescimento de sete populações de P. antidotale cultivadas em vasos de plástico cheios de solo foram submetidos à seca progressiva, retendo a irrigação com água por três semanas. A seca progressiva reduziu o teor de umidade do solo, teor de água relativo nas folhas, pigmentos fotossintéticos e biomassa fresca e seca dos brotos em todas as sete populações. Populações de Dingarh Fort, Dingarh Grassland e Haiderwali tiveram maior crescimento do que as de outras populações. As populações de Cholistani, especialmente em Dingarh Grassland e Haiderwali, apresentaram maior capacidade de ajuste osmótico, refletido pelo potencial osmótico e maior acúmulo de proteínas solúveis totais. H2O2 máximo sob estresse hídrico foi observado em populações de Muzaffargarh e Khanewal, mas estas foram intermediárias no conteúdo de MDA. Sob estresse hídrico, as populações de Muzaffargarh e Dingarh Fort tiveram maior acúmulo de K+ em suas folhas. Durante a seca progressiva, as populações não cholistanesas mostraram rolagem completa das folhas após 23 dias de seca, e essas populações não conseguiram suportar mais condições de estresse hídrico, enquanto as populações cholistani toleraram mais condições de estresse hídrico por 31 dias. Além disso, a seca progressiva causou danos ao PSII após 19 dias e tornou-se severa após 23 dias em populações não cholistanesas de P. antidotale do que em populações cholistanesas.

Comparison of Quality Change During Processing Process of Achyranthis Bidentatae Radix from Different Origins Based on Color-component Correlation Analysis / 中国实验方剂学杂志

ObjectiveTaking Achyranthis Bidentatae Radix（ABR） from different origins as samples， to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees， and clarify the correlation and change law between color and composition in the processing process of ABR， so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process， and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA） and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography（HPLC）， the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis， and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis， and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing， and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural， polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone， ginsenoside Ro， chikusetsusaponin Ⅳa and polysaccharides as variables， the discriminant function was established respectively， and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters， and the results could significantly distinguish different processed products. During the process of wine and salt processing， the contents of 5-hydroxymethylfurfural， ginsenoside Ro， and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree， while the contents of polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone and polysaccharides showed a gradual decreasing trend， indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value（L*） and the total color difference value（E*ab）（P<0.01）， and positively correlated with the red-green value（a*） and the yellow-blue value（b*）（P<0.01）， and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab（P<0.01）. The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis， and their accuracy rates in the training samples were 93.75% and 95.83%， respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution， and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent， and the color value can better distinguish ABR with different processing degrees， and the color of ABR is related to some representative components in the processing process， indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.

Validez de las reglas de un análisis estadístico implicativo según juicio de expertos

Introducción: una nueva metodología para el empleo del análisis estadístico implicativo contextualizado a las investigaciones médicas de causalidad brinda reglas y meta-reglas que deben corresponderse con la práctica médica, lo cual se desconoce. Objetivo: evaluar la calidad de las reglas derivadas de la aplicación del análisis estadístico implicativo en las investigaciones médicas de causalidad. Métodos: se realizó un estudio observacional con la aplicación de técnicas cualitativas de tipo criterio de expertos. Los 33 expertos de mayor puntuación emitieron su juicio, mediante una escala Likert de cinco puntos, acerca de la frecuencia con que se cumplen en la práctica médica 23 reglas derivadas de la aplicación del análisis estadístico implicativo en tres estudios para la identificación de factores pronósticos en cáncer de mama. Las opiniones se procesaron mediante el método Delphi en dos rondas y se trianguló con la validez racional de estas reglas. Resultados: los expertos consideraron que cerca del 74 % de las reglas se cumplen en la práctica médica siempre o frecuentemente y sólo una regla resultó absurda. En la segunda ronda se trataron las tres reglas en las que no existió un acuerdo perfecto, en la cual se ratificó una regla como absurda y aumentó el nivel de acuerdo. La triangulación permitió encontrar contradicciones literatura-experto que facilitaron la identificación de problemas en la redacción de la interpretación de las reglas. Conclusiones: las reglas evaluadas reflejan, en general, lo que ocurre en la práctica médica y aquellas que resultan absurdas alertan al investigador sobre un posible sesgo de confusión.

Introduction: A new methodology for the use of contextualized statistical implicative analysis in causality medical research provides rules and meta-rules that must correspond to medical practice, which is unknown. Objective: To evaluate the quality of the rules derived from the application of the statistical implicative analysis in causality medical research. Methods: An observational study was carried out applying qualitative techniques based on expert judgement. Using a five-point Likert scale, the 33 experts with the highest score expressed their judgment about the frequency of the fulfilment of the 23 rules derived from the application of the statistical implicative analysis in three studies in order to identify prognostic factors for breast cancer. Opinions were processed using the two-round Delphi method, and the rational validity of these rules was triangulated. Results: The experts considered that about 74% of the rules are always or frequently followed in medical practice; only one rule was absurd. In the second round, the three rules in which there was no perfect agreement were discussed; one rule was ratified as absurd and there was an increase in the level of agreement. The triangulation allowed us to find contradictions between literature and experts, which facilitated the identification of problems in the drafting of the interpretation of the rules. Conclusions: The rules evaluated generally reflect what happens in medical practice and those that are absurd warn the researcher about the possibility of a confusion bias.

Como indexar una revista científica usando WordPress en Google Scholar

Los avances científicos han facilitado la difusión del conocimiento, encontrándose los más recientes hallazgos rápidamente en Internet, esto ha producido la migración de las revistas desde lo impreso a lo digital, pero este proceso no siempre se realiza adecuadamente, por lo que actualmente existen revistas, y en consecuencia sus publicaciones, que no se logran encontrar en los buscadores académicos, lo que se debe al uso de los softwares inadecuados o en su defecto a una mala configuración de los que se han implementado. En esta línea la recomendación es usar Open Journal System, un software diseñado para la publicación científica, pero varias revistas usan gestores de contenido como WordPress, por su facilidad de implementación y personalización aun cuando estos presenten limitaciones en el aspecto editorial. A continuación, se expone un método para la correcta indexación de revistas confeccionadas en WordPress en el buscador Google Scholar.

Scientific advances have facilitated the dissemination of knowledge, and the latest discoveries can be easily found on the Internet. This has produced the migration of journals from print to digital; however, this process is not always done properly since there are journals, and consequently their publications, which are not currently found in academic search engines due to the inappropriate use of software or otherwise to a misconfiguration of those that have been implemented. In this line, the recommendation is to use Open Journal System, a software designed for scientific publication; on the other hand, several journals use content manager systems such as WordPress because of its easy implementation and customization even when they present editorial constrains. The following is a method for the correct indexing of journals created in WordPress in the Google Scholar search engine.

Untangle the relationship of muscle mass and bone mineral content on handgrip strength: Results of ELSA-Brasil / Desvendando a relação entre massa muscular e conteúdo mineral ósseo na força de preensão palmar: Resultados do ELSA-Brasil

Abstract The study aims to investigate the independent association of muscle mass (MM) and bone mineral content (BMC) in the performance of the handgrip strength (HGS) test and whether there is effect modification by sex and age. In 12,491 participants from the ELSA-Brasil we estimated the associations between MM, BMC and HGS using linear regression models. All the analyses were performed for total population, also stratified for sex and age. For total population an interaction term was included between each explanatory variable of interest with sex and age to verify the presence of effect modification. We observed that the higher quintiles of MM and BMC were associated to an increasing in the mean of HGS compared to the first quintile, with greater magnitudes in men compared to women, also adults compared to elderly. When we estimated the independent effect of each exposure of interest, MM showed stronger effect in HGS in women, men and adults then BMC. In conclusion, we observed that higher amounts of MM and BMC are associated with higher HGS, regardless of sociodemographic characteristics, health conditions and lifestyle, with this effect being greater in men and adults.

Resumo O estudo tem como objetivo investigar a associação independente da massa muscular (MM) e conteúdo mineral ósseo (CMO) na realização do teste de força de preensão manual (FPM) e se há modificação do efeito por sexo e idade. Em 12.491 participantes do ELSA-Brasil estimamos as associações entre MM, CMO e FPM usando modelos de regressão linear. Todas as análises foram realizadas para a população total, também estratificada por sexo e idade. Para a população total foi incluído um termo de interação entre cada variável explicativa de interesse com sexo e idade para verificar a presença de modificação de efeito. Observamos que os maiores quintis de MM e BMC estiveram associados a um aumento na média da FPM em relação ao primeiro quintil, com maiores magnitudes em homens em relação a mulheres, também em adultos em relação a idosos. Quando estimamos o efeito independente de cada exposição de interesse, MM mostrou efeito mais forte na FPM em mulheres, homens e adultos do que BMC. Em conclusão, observamos que maiores quantidades de MM e BMC estão associadas a maior FPM, independentemente das características sociodemográficas, condições de saúde e estilo de vida, sendo esse efeito maior em homens e adultos.

Effect of Harvesting Stage and Drying Method on Cowpea Leaf Nutrient Composition

Cowpea leaves are lost annually due to infestation and spoilage when being transported to clients and the losses at the local markets are brought on by inadequate postharvest handling procedures and market glut, particularly during peak seasons. High moisture content from the cowpea leaves at harvest stage may contribute to increased spoilage hence lowering quantity and quality. The choice of appropriate harvesting stage and drying method can help to reduce this problem. The aim of this study was to determine the best harvesting stage and efficient drying method that would maintain high leaf nutrient composition. Cowpeas variety M66 was used for the research and the treatments included three harvesting stages (21, 35 and 49 days after sowing [DAS]), three drying methods (open sun, solar dryer and oven. Data was collected on iron, calcium, crude fibre, beta carotene, protein and moisture content. The data was subjected for variance using Statistical Analysis System 9.2 edition and significantly different means separated using least significant difference at 5%. The results indicated significant (p<0.05) differences in moisture, calcium, proteins, beta carotene and crude fibre content in both trials. Harvest stage and drying method did not significantly (p<0.05) influence the iron content. Oven and solar drying methods showed better nutrient and mineral retention in the three harvesting stages when compared to the open sun drying method.

Aim: To study the production of Nutrient – Dense Composite Flour from the blends of whole wheat flour, soybean flour (full fat) and oyster meat powder. Study Design: The study was design using the D-optimal combination design of Response Surface Methodology (RSM). Place and Duration of Study: The study was carried out at Department of Food, Nutrition and Home Science, University of Port Harcourt (Processing of raw materials) and the Department of Food Technology, Federal Institute of industrial research Oshodi, Lagos (Analysis of raw materials) between October 2021 and August 2022. Methodology: The raw materials were each processed to have wholesome flours, and then they were combined according to the matrix generated, which had ranges of 70 – 100%, 0 – 22%, and 0 – 8% for whole wheat flour (WWF), soybean flour (SBF) and oyster meat powder (OMP) respectively. Results: The design was used to assess the significance (5% probability) of the moisture, fat, and protein content, which ranged from 8.09 to 11.37%, 1.80 to 8.52% and 9.70 to 19.07% respectively; the water absorption (72.00 - 79.10BU), dough stability (9.3 - 17.5BU) and mixing tolerance index (25 - 50BU); and lightness and yellowness, which ranged from 65.48 - 83.2 and 13.77 - 23.58 respectively, of the flour blends. Protein content, water absorption dough stability, and mixing tolerance index were prioritized while moisture content, fat content, and yellowness were minimized for the numerical optimization of the responses. This study highlights the possibilities of utilizing non-conventional raw materials in the production of composite flour with balance nutritional and baking qualities. Conclusion: The best flour combination was 72.51% whole wheat flour, 19.63% soybean flour, and 7.86% oyster meat powder.

Theory and health disparities: Explaining the relevance of theory in public health research in India

This paper aims to address the concern that quantitative public health studies do not integrate theoretical considerations. This qualitative study uses content analysis to explore the application of theory in Indian public health articles listed on PubMed. Social determinants such as poverty, income, social class, education, gender, caste, socioeconomic position, socioeconomic status, immigrant status, and wealth were the keywords used to identify the articles analysed in this study. From a selection of 91 public health articles, we identified potential theoretical frameworks based on the pathways/recommendations/explanations mentioned. Additionally, using the case of tuberculosis in India, we highlight how theoretical perspectives play a critical role in providing a holistic view of major health challenges. Finally, by emphasising the need to adopt a theoretical perspective in empirical quantitative research on public health in India, we hope to motivate scholars to include a theory or theoretical paradigm in their future research.

Proximate and Mineral Composition of Some Foreign and Local Rice Varieties Sold in Mile 3 Market, Port Harcourt, Rivers State, Nigeria

Rice is a staple food in many countries of Africa and it is nutritionally beneficial. This research work compared the proximate composition and mineral composition of some local and foreign rice varieties. Four varieties of rice were analyzed; two types of local rice designated as (L1 and L2) and two types of foreign rice (F1 and F2). The proximate composition such as moisture content, ash content, carbohydrate content, crude protein, crude fiber and total fat were evaluated using standard methods. The result of the analysis showed that the moisture content was lowest in L1 (8.56 ± 0.26g) and highest in sample L2 (9.47 ± 0.48g). All the four varieties recorded high carbohydrate content. The fat content of L1 and L2 (1.19±0.20 - 2.48±0.90) were significantly higher (p<0.05) when compared to F1 and F2 (1.69±0.30 – 1.99± 0.20a). Crude fiber content for L1 and L2 (1.49±0.09 -1.69±0.09) were statistically higher compared to F1 and F2 (0.29±0.09b -0.39±0.01b). Crude protein for L1 and L2 (7.89±0.09 – 8.09±0.22) were significantly higher when compared to F1 and F2 (6.34± 0.22b – 7.22± 0.66). Ash content for L1 and L2 (0.60± 0.01-0.68±0.32) were statistically lower compared to F1 and F2 (0.62±0.08 – 1.20± 0.20) Potassium and Zinc showed no significant difference in all samples apart from F1 where Potassium and Zinc were significantly different. Calcium values for foreign rice showed significant difference when compared to the values for local rice. Local rice appeared to have a relatively higher level of iron when compared to all the foreign rice samples. The values obtained from this study indicates that Nigerian local rice varieties are nutritionally better compared to foreign rice varieties.

Configurações explicativas do desenvolvimento da resiliência nas redes de suprimentos da administração pública / Ámbitos explicativos del desarrollo de la resiliencia en las redes de abastecimiento de las administraciones públicas / Explanatory settings of the development of resilience in public administration supply networks

Resumo O capital social é uma lente teórica importante para explicar os relacionamentos interorganizacionais e a construção da resiliência nas redes de suprimentos. Para corroborar essa perspectiva, este estudo visa identificar quais atributos do capital social contribuem para explicar o desenvolvimento da resiliência nas redes de suprimentos da administração pública e de que forma eles se combinam nessa explicação. Para tanto, foi realizada uma pesquisa qualitativa e descritiva que utilizou entrevistas com a técnica da grade de repertório para a coleta de dados. Os dados foram analisados mediante a análise de conteúdo de Honey e a análise de coincidência (CNA). Os resultados da pesquisa indicam que o capital social se mostrou fundamental para desenvolver resiliência nas redes de suprimentos na administração pública, por meio dos atributos de compartilhamento de informações técnicas; precisão na comunicação; antecipação na comunicação de informações relevantes; reciprocidade; confiança; transparência e comprometimento. A originalidade do estudo reside na utilização da teoria do capital social em estudos sobre resiliência na administração pública e na adoção de um método de coleta e análise de dados robusto e ainda não explorado em pesquisas na administração pública brasileira. As principais contribuições do estudo foram: 1) destacar o capital social como constructo multinível que influencia o desenvolvimento da resiliência; 2) ampliar os estudos sobre resiliência na administração pública; 3) fornecer informações que podem ser utilizadas por gestores públicos, a fim de evitar ou minimizar a ocorrência de riscos que comprometam a prestação de serviços públicos e 4) adotar um método de pesquisa inédito na administração pública brasileira.

Abstract Social capital is an important theoretical lens for explaining interorganizational relationships and building resilience in supply networks. This study corroborates this perspective, aiming to identify which attributes of social capital contribute to explaining the development of resilience in public administration supply networks and how they combine in this explanation. A qualitative and descriptive research was carried out, using interviews with the repertoire grid technique for data collection. Data were analyzed using Honey's content analysis and coincidence analysis (CNA). The research results indicate that social capital proved to be fundamental to developing resilience in supply networks in public administration, through the attributes of sharing technical information, precision in communication, anticipation in communicating relevant information, reciprocity, trust, transparency, and commitment. The originality of the study lies in the use of social capital theory in studies on resilience in public administration and in the adoption of a robust data collection and analysis method that has not yet been explored in research in Brazilian public administration. The main contributions of the study were: (1) to highlight social capital as a multilevel construct that influences the development of resilience, (2) to expand studies on resilience in public administration, (3) to provide information that public managers can use to avoid or minimize the risks that jeopardize the provision of public services, and (4) to adopt an unprecedented research method in the Brazilian public administration.

Contenido de sodio en antimicrobianos parenterales: Una fuente extra de sodio a considerarse en pacientes hospitalizados

Los antimicrobianos parenterales son esenciales en el tratamiento de infecciones intrahospitalarias, sin embargo, es importante considerar la carga de sodio y volumen que pueden aportar, especialmente, en pacientes con restricción sódica. En el presente estudio se identificaron los antimicrobianos parenterales usados en uno de los hospitales más grandes del Perú. Se revisó la cantidad de sodio intrínseco y se calculó la cantidad de sodio total por día de tratamiento según el régimen frecuentemente usado en adultos. Como resultado, se encontró que 22% de las terapias antimicrobianas superaban el requerimiento de sodio diario, lo que podría ser perjudicial para pacientes con insuficiencia cardiaca, enfermedad renal crónica, con cirrosis hepática, entre otros.

Parenteral antibiotics are essential in the treatment of nosocomial infections; however, their sodium load and volume should be considered as an extra source, especially, in patients with sodium restriction. In this study, we identified the parental antibiotics used in one of the largest hospitals in Peru. We reviewed the amount of intrinsic sodium and we calculated the sodium load per day of treatment according to the commonly used regimen in adults. As a result, we found that 22% of the antibiotic treatment regimens exceed the daily sodium requirement, which could be harmful for patients with heart failure, chronic kidney disease, liver cirrhosis, among others.

Antioxidant potential and α-glucosidase inhibitory activity of onion (Allium cepa L. ) peel and bulb extracts / Atividade antioxidante e potencial inibidor de glucosidase de extratos de casca e bulbo de cebola (Allium cepa) preparados por etanol e água

Abstract Allium cepa L. is a commonly consumed vegetable that belongs to the Amaryllidaceae family and contains nutrients and antioxidants in ample amounts. In spite of the valuable food applications of onion bulb, its peel and outer fleshy layers are generally regarded as waste and exploration of their nutritional and therapeutic potential is still in progress with a very slow progression rate. The present study was designed with the purpose of doing a comparative analysis of the antioxidant potential of two parts of Allium cepa, i.g., bulb (edible part) and outer fleshy layers and dry peels (inedible part). Moreover, the inhibitory effect of the onion bulb and peel extracts on rat intestinal α-glucosidase and pancreatic α-amylase of porcine was also evaluated. The antioxidant potential of onion peel and bulb extracts were evaluated using 2,2-diphenyl- 1-picryl hydrazyl (DPPH), ferric-reducing antioxidant power assay (FRAP), 2,2'-azino-bis- 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assay, H2O2 radical scavenging activity and Fe2+ chelating activity. Total flavonoids and phenolic content of ethanolic extract of onion peel were significantly greater as compared to that of onion bulb. Ethanolic extract of onion peel also presented better antioxidant and free-radical scavenging activity as compared to the ethanolic extract of bulb, while the aqueous extract of bulb presented weakest antioxidative potential. Onion peel extract's α-glucosidase inhibition potential was also correlated with their phenolic and flavonoid contents. The current findings presented onion peel as a possible source of antioxidative agents and phenolic compounds that might be beneficial against development of various common chronic diseases that might have an association with oxidative stress. Besides, outer dry layers and fleshy peels of onion exhibited higher phenolic content and antioxidant activities, compared to the inner bulb. The information obtained by the present study can be useful in promoting the use of vegetable parts other than the edible mesocarp for several future food applications, rather than these being wasted.

Resumo Allium cepa pertence à família Liliaceae e é rica em nutrientes e antioxidantes. Apesar das expressivas aplicações alimentares do bulbo da cebola, sua casca e outras camadas externas são geralmente consideradas resíduos, e seu potencial nutricional e terapêutico ainda é pouco explorado. O presente estudo foi delineado com o objetivo de investigar comparativamente o potencial antioxidante de duas partes de Allium cepa, por exemplo o bulbo (parte comestível) e camadas externas e cascas secas (parte não comestível). Além disso, o efeito inibitório dos extratos do bulbo de cebola e casca sobre a α-glucosidase intestinal de ratos e α-amilase pancreática suína também foi avaliado. O potencial antioxidante dos extratos da casca de cebola e bulbo foi avaliado utilizando-se 2,2-difenil-1-picrilhidrazil (DPPH), método de poder antioxidante de redução do ferro (FRAP), método 2,2'-azino-bis-3-etilbenzotiazolina-6-ácido sulfônico (ABTS) de eliminação de radicais, atividade de eliminação de radicais H2O2 e atividade quelante do Fe2+. Os flavonoides totais e os teores fenólicos do extrato de etanol da casca de cebola foram significativamente maiores quando comparados ao do bulbo. O extrato de etanol da casca de cebola também apresentou melhor atividade antioxidante e eliminação de radicais livres quando comparado ao extrato de etanol do bulbo, enquanto o extrato aquoso de bulbo apresentou menor potencial antioxidante. O potencial de inibição da α-glicosidase dos extratos de casca de cebola correlacionou-se com seus teores fenólicos e de flavonoides. Os resultados encontrados identificaram que a casca de cebola é uma possível fonte de agentes antioxidantes e compostos fenólicos que podem ser benéficos contra o desenvolvimento de várias doenças crônicas que estão associadas ao estresse oxidativo. Além disso, as camadas externas secas e as cascas da cebola exibiram maior conteúdo fenólico e atividades antioxidantes, em comparação com o bulbo interno. As informações obtidas pelo presente estudo podem promover o uso de outras partes vegetais além do mesocarpo comestível para futuras aplicações em alimentos, ao invés de serem desperdiçadas.

Cloning and Expression Patterns of Coumarate-3-hydroxylase Gene from Angelica sinensis and Its Correlation with Content of Ferulic Acid / 中国实验方剂学杂志

ObjectiveTo clone coumarate-3-hydroxylase gene （C3H） from Angelica sinensis， and analyze the correlation between its bioinformatics， expression patterns and content of ferulic acid， and to explore the functions of ASC3H. MethodReal-time polymerase chain reaction （Real-time PCR） was used to clone the full-length cDNA of ASC3H based on the transcriptome dataset of A. sinensis， and the bioinformatics analysis of the gene sequence was carried out. Real-time PCR and high performance liquid chromatography （HPLC） were used to determine relative expression of ASC3H and content of ferulic acid in different root tissues of A. sinensis （periderm， cortex and stele）. ResultThe open reading frame （ORF） of ASC3H （GenBank accession number： MN2550298） was 1 530 bp， encoding 509 amino acids， with a theoretical molecular weight of 57.86 kDa and an isoelectric point of 8.36. It was a hydrophilic protein that was located in the chloroplast with multiple phosphorylation sites and a transmembrane region， and contained a conserved domain CGYDWPKGYGPIINVW_P450 （383-399 aa） in cytochrome P450. Multiple amino acid sequence alignment analysis showed that ASC3H had high similarity with C3H from other plants， especially Ammi majus in Umbelliferae. The Real-time PCR revealed that ASC3H had different expressions in periderm， cortex and stele tissues of A. sinensis roots. It was found from HPLC that the cortex tissues had the highest content of ferulic acid， and the stele tissues had the lowest. ConclusionASC3H was successfully cloned from A. sinensis， and its sequence characteristics were understood more clearly， suggesting that ASC3H might be involved in the ferulic acid biosynthesis pathway of A. sinensis. This paper provided a basis for further studying the functions of the gene and exploring the biosynthesis and regulation mechanism of ferulic acid in A. sinensis， while laying the foundation for the genetic improvement of A. sinensis．

Mixed venous to arterial CO 2 gap as a marker to identify fluid responsiveness in septic shock patients / 中华急诊医学杂志

Objective:To investigate the value of the venous-to-arterial CO 2 gap (Δ CO 2 gap) before and after the fluid challenge (FC) in determining the fluid responsivenessin septic shock patients. Methods:A total of 104 septic shock patients admitted to the Medical Intensive Care Unit (MICU) of Peking Union Medical College Hospital were included in the retrospective study. All patients were monitored by Swan Ganz floating catheter during the FC. Hemodynamics and blood gas indices were collected before FC (T0) and immediately (T1), 10 min (T2), 30 min (T3) and 60 min (T4) after FC. Responders were defined as patients with a > 10% increase in cardiac output (CO) after FC. Spearman correlation analysis was used to evaluate the correlation between CO 2 gap and CO. The value of ΔCO2 gap were calculated by the area under the receiver operating characteristic (AUROC) curve in the whole population. Results:Among 104 patients, the effective rates of FC at T1, T2, T3 and T4 were 59% (61/104), 72% (75/104), 73% (76/104), and 77% (80/104), respectively. CO of patients in the reactive group was lower than that in the non-reactive group at T2 [6.0 (4.7, 7.5) vs. 7.2 (6.4, 8.5) L/min, P=0.019], and there was no significant difference in CO 2 gap between the two groups before FC. Spearman correlation analysis showed that CO 2 gap was negatively correlated with CO, and the correlations between CO 2 content gap and CO was -0.34, and -0.33 of CO 2 pressure gap and CO, respectively (both P <0.05). ROC curve analysis showed that the ΔCO 2 gap at T1 could weakly judge the reactivity at T2, T3 and T4, but could not judge the reactivity at T1. The AUROC at T2 was 0.669 of ΔCO 2 content gap and 0.684 of ΔCO 2 pressure gap (both P <0.05). Conclusions:The evaluate time judging the effect of FC should be appropriately extended. The change value of CO 2 gap before and immediately after volume expansion in septic shock patients can judge the fluid responsiveness within 10 min after FC.

Progress on the relationship between hyperoxia exposure and renal development in premature infants / 国际儿科学杂志

Oxygen therapy is a common therapeutic method to improve oxygenation of premature infants, but long-term exposure to high oxygen can cause damage to immature organs and abnormal development.In addition to bronchopulmonary dysplasia and retinopathy, high oxygen levels will increase the risk of chronic kidney disease and hypertension in adulthood.High oxygen exposure can lead to kidney damage and developmental abnormalities in premature infants, including reduced number and increased volume of glomeruli, renal cell apoptosis, and abnormal development of renal tubules.The mechanism may be related to abnormal signaling pathways related to renal development.This article reviews the relationship between hyperoxia and kidney development and the possible mechanism of kidney disease, in an attempt to provide theoretical reference for early clinical intervention.
