Authors: Mulim Henrique Alberto , Pinto Luis Fernando Batista , Valloto Altair Antônio , Pedrosa Victor Breno
Published: May 2020

Objective: The objective of this study was to evaluate the genetic behavior of a population of Holstein cattle in response to the variation of environmental temperature by analyzing the effects of genotype by environment interaction (GEI) through reaction norms for the somatic cell score (SCS).Methods: Data was collected for 67,206 primiparous cows from the database of the Paraná Holstein Breeders Association in Brazil, with the aim of evaluating the temperature effect, considered as an environmental variable, distinguished under six gradients, with the variation range found being 17°C to 19.5°C, over the region. A reaction norm model was adopted utilizing the fourth order under the Legendre polynomials, using the mixed models of analysis by the restricted maximum likelihood method by the WOMBAT software. Additionally, the genetic behavior of the 15 most representative bulls was assessed, in response to the changes in the temperature gradient.Results: A mean score of 2.66 and a heritability variation from 0.17 to 0.23 was found in the regional temperature increase. The correlation between the environmental gradients proved to be higher than 0.80. Distinctive genetic behaviors were observed according to the increase in regional temperature, with an observed increase of up to 0.258 in the breeding values of some animals, as well as a reduction in the breeding of up to 0.793, with occasional reclassifications being observed as the temperature increased.Conclusion: Non-relevant GEI for SCS were observed in Holstein cattle herds of southern Brazil. Thus, the inclusion of the temperature effect in the model of genetic evaluation of SCS for the southern Brazilian Holstein breed is not required.
Potential immune-modulatory effects of wheat phytase on the performance of a mouse macrophage cell line, Raw 264.7, exposed to long-chain inorganic polyphosphate
Authors: An Jeongmin , Cho Jaiesoon
Published: May 2020

Objective: This experiment was conducted to find out the immunological effects of wheat phytase when long-chain inorganic polyphosphate (polyP) treated with wheat phytase was added to a macrophage cell line, Raw 264.7, when compared to intact long-chain polyP.Methods: Nitric oxide (NO) production of Raw 264.7 cells exposed to P700, a long-chain polyP with an average of 1,150 phosphate residues, treated with or without wheat phytase, was measured by Griess method. Phagocytosis assay of P700 treated with or without phytase in Raw 264.7 cells was investigated using neutral red uptake. The secretion of tumor necrosis factor α (TNF-α) by Raw 264.7 cells with wheat phytase-treated P700 compared to intact P700 was observed by using Mouse TNF-α enzyme-linked immunosorbent assay kit.Results: P700 treated with wheat phytase effectively increased NO production of Raw 264.7 cells by 172% when compared with intact P700 at 12 h exposure. At 5 mM of P700 concentration, wheat phytase promoted NO production of macrophages most strongly. P700, treated with wheat phytase, stimulated phagocytosis in macrophages at 12 h exposure by about 1.7-fold compared to intact P700. In addition, P700 treated with wheat phytase effectively increased in vitro phagocytic activity of Raw 264.7 cells at a concentration above 5 mM when compared to intact P700. P700 dephosphorylated by wheat phytase increased the release of TNF-α from Raw 264.7 cells by 143% over that from intact P700 after 6 h exposure. At the concentration of 50 μM P700, wheat phytase increased the secretion of cytokine, TNF-α, by 124% over that from intact P700.Conclusion: In animal husbandry, wheat phytase can mitigate the long-chain polyP causing damage by improving the immune capabilities of macrophages in the host. Thus, wheat phytase has potential as an immunological modulator and future feed additive for regulating immune responses caused by inflammation induced by long-chain polyP from bacterial infection.

Objective: Wheat bran (WB) was co-fermented with Aspergillus oryzae and phytase (Phy) to determine whether co-fermentation improve WB phosphorus and fiber utilization in Isa-brown layers.Methods: A total of 112 Isa brown layer were randomly divided into 7 treatments with 8 replicates per a treatment and 2 hens per a replicate. The treatments included basal diet (control), basal diet supplemented with 250 unit/kg Phy (control+Phy), diet with 10% WB (10% WB), diet with 5% WB and 250 unit/kg Phy (5% WB+Phy) diet with 10% WB and 250 unit/kg Phy (10% WB+Phy), diet with 5% fermented WB supplemented with molasses and phy (PCFWH) and 125 unit/kg Phy (5% PCFWH), and diet with 10% PCFWH (10% PCFWH). The intestinal microbial population, intestinal morphology, serum antioxidant enzyme activities, and excreta phosphorus content were assessed.Results: In PCFWH, spore counts, protease activity, xylanase activity, and ferulic acid were 8.50 log/g dry matter (DM), 190 unit/g DM, 120 unit/g DM, and 127 μg/g, respectively. Xylobiose and xylotriose were released in PCFWH, while they were not detectable in WB. Antioxidant capacity was also enhanced in PCFWH compared to WB. The 10% WB+Phy and 10% PCFWH groups produced higher egg mass, but hens fed 5% WB+Phy had the lowest amount of feed intake. Eggs from 10% PCFWH had better eggshell weight, eggshell strength, and eggshell thickness. Birds fed with 10% PCFWH also had higher serum superoxide dismutase and catalase activities. Compare to control, 10% PCFWH significantly reduced excreta phosphorus content.Conclusion: Diet inclusion of 10% PCFWH improved egg quality, antioxidant status, and excreta phosphorus content of laying hens.

Background: Improving lifestyle, increasing lifespan and life expectancy have led to the phenomenon of aging in societies. The increasing population of older adults is one of the most important economic, social, and health challenges in the current century. Objectives: This study was conducted to measure the mental health of older adults in Qom City and its relationship with socioeconomic factors. Methods: This is a cross-sectional descriptive-analytical study on 400 older adults over 60 years in the urban areas of Qom in 2018. A multi-stage sampling method was used for this study. The research tools were a demographic questionnaire, the Kessler Psychological Distress scale (K6), and a standard psychological well-being scale. Data were analyzed by Stata 12 software using the t-test. The significance level was considered less than 0.05. Results: Considering the mental health status, based on the K6, 55% of the elderly showed signs of low depression anxiety, 34% moderate, and 11% showed severe anxiety symptoms. Regarding the status of well-being, 49.50% were in good condition (11.3 ± 3.3), 27.75% were in moderate condition (13.8 ± 2.9), and 22.75% were in poor condition (7.3 ± 2.6). Anxiety and depression had significant relationships with gender, having an illness, marital status, having a caregiver, and income. Conclusions: The results showed that about half of the elderly in Qom had moderate anxiety and depression disorders, as well as moderate mental well-being, which indicates the moderate level of anxiety and mental disorders in the elderly in Qom.
A Defence of Sexual Inclusion
Authors: Danaher John ,   Department of Philosophy, Florida State University
Published: May 2020

This article argues that access to meaningful sexual experience should be included within the set of the goods that are subject to principles of distributive justice. It argues that some people are currently unjustly excluded from meaningful sexual experience and it is not implausible to suggest that they might thereby have certain claim rights to sexual inclusion. This does not entail that anyone has a right to sex with another person, but it does entail that duties may be imposed on society to foster greater sexual inclusion. This is a controversial thesis and this article addresses this controversy by engaging with four major objections to it: the misogyny objection; the impossibility objection; the stigmatisation objection; and the unjust social engineering objection.

Published: May 2020

This paper takes a technical services perspective on user experience (UX) research into student searching behaviors. In this observational study, students were free to search as they normally would while conducting research for an upcoming essay or assignment. Researchers took careful note of the search process, including how searches were composed and which metadata fields students looked at in their results lists. The findings of the study, and how local technical services staff responded to them, are discussed in this paper. The project was a useful way to prioritize the work of technical services based on insights from user searching behavior and to help ensure library resources are discoverable in the most effective manner.

Epistemologia insubmissa feminista negra decolonial
Authors: Figueiredo Angela
Published: May 2020

Neste texto, propomos uma revisão/análise das abordagens teórico-metodológicas do feminismo nos últimos anos. Destacamos que a epistemologia feminista negra articula teoria, metodologia e prática política com vistas à transformação social. A análise realizada revela um diálogo constante entre o feminismo negro brasileiro e o feminismo afro-americano, ainda que as editoras brasileiras só tenham traduzido a contribuição feminista negra e descoberto este filão comercial nos últimos cinco anos. A popularização do conceito de interseccionalidade no Brasil é relativamente recente para um conceito que fez 30 anos, sendo atualmente o mais utilizado aqui para analisar as relações e as interconexões possíveis entre as categorias de gênero, raça, classe, sexualidade, geração etc. É importante destacar o significativo crescimento das pesquisas, livros e artigos acadêmicos produzidos por mulheres negras, bem como a divulgação de ideias e reflexões políticas através do uso das plataformas digitais, tais como sites, blogs, facebook, Instagram e YouTube. Este movimento, que algumas autoras têm definido como a quarta onda feminista, mas que algumas mulheres negras preferem chamar de maré feminista negra, ampliou o referencial teórico, incluindo as contribuições de autoras africanas e afrodiaspóricas, como por exemplo, Oyèrónkẹ́ Oyěwùmí (2017) e Grada Kilomba (2019), e recuperou contribuições negras, notadamente femininas negras que foram historicamente silenciadas, através de práticas epistemicidas, construindo desse modo uma nova epistemologia feminista negra.Palavras-chave: Epistemologia.

Travesti: textos-vestígios na construção de uma identidade - Jornal Lampião da Esquina (1978-1981)
Authors: Canabarro Ronaldo Pires , Meyrer Marlise Regina
Published: May 2020

A pesquisa analisa as construções discursivas da imagem de travestis, no jornal Lampião da Esquina (1978-1981). O estudo traz aspectos que colaboram para ampliar o entendimento de como a identidade das travestis foi se construindo enquanto identidade política, durante as décadas de 70 e 80. Ainda, contribui para o entendimento de como as identidades de lésbicas, gueis/gays, bissexuais, travestis e transexuais se afirmaram e se constituíram como força política no Brasil. A partir da metodologia da análise de conteúdo, buscamos identificar o gênero sócio gramatical a que se referem os autores do jornal sobre travestis, percebendo como o uso comum dos condicionantes gramaticais masculinos ou femininos contribuiu para a afirmação/criação das identidades travestis. Da mesma forma, identificamos uma polaridade conflituosa nos discursos do jornal entre as expressões fazer e ser travesti. Palavras-chave: Travesti. Identidade. Gênero. Lampião da Esquina. Imprensa.
Triple presencia femenina en torno a los trabajos: mujeres de sectores populares, participación política y sostenibilidad de la vida
Authors: Díaz Lozano Juliana
Published: May 2020

Este artículo analiza las experiencias de mujeres que integran organizaciones barriales populares en relación con el trabajo. Para ello, se parte de reconstruir las condiciones de vida de las mujeres trabajadoras, de sectores populares y racializadas en las periferias argentinas, tomando en consideración, entre otros elementos, la propuesta estatal de políticas sociales y vinculadas al trabajo para este sector. Para abordar las experiencias laborales de las mujeres, se recuperan los aportes de la Economía Feminista sobre la ampliación de la categoría trabajo, poniendo la sostenibilidad de la vida en el centro. Desde esta óptica, se considera la totalidad del trabajo realizado por las mujeres como un continuo, que entrelaza diferentes actividades remuneradas, de cuidados o reproductivo y comunitario, a fin de sostener sus vidas y las de sus familias. A partir de analizar la totalidad de la experiencia cotidiana femenina y los usos del tiempo que realizan en los distintos ámbitos de desempeño, discutimos la pertinencia de la idea de jornadas laborales; postulamos, en cambio, la mayor utilidad del concepto de doble presencia femenina; y afirmamos la existencia de una triple presencia para las mujeres militantes.Palabras clave: Mujeres.

A mandioca é um dos alimentos mais conhecidos no Brasil e seu cultivo é muito importante, especialmente para a agricultura familiar. Suas raízes tuberosas, ricas em carboidratos, podem ser colhidas em larga faixa de tempo, dependendo da etnovariedade e da região de cultivo, indicando, portanto, a necessidade de se definir a melhor época de colheita, visando aumento da produtividade e maximização da área agrícola. Diante disso, o objetivo deste trabalho foi avaliar o efeito de quatro épocas de colheita (seis, oito, dez e doze meses pós-plantio) sobre características agronômicas de quatro etnovariedades de mandioca (Cacau branca, Cacau roxa, Cacau amarela e Mandioca pão), nas condições edafoclimáticas do município de Alta Floresta, Mato Grosso, Brasil. O delineamento experimental foi em blocos casualizados, com quatro repetições em um esquema de parcelas (etnovariedades) e subparcelas (épocas de colheita). Em cada época de colheita foram avaliados os descritores agronômicos: produtividade da parte aérea, produtividade de raízes tuberosas, índice de colheita, número de raízes por planta, comprimento e diâmetro médio das raízes. Os dados foram submetidos à análise de variância e ao ajuste de modelo de regressão polinomial. Os resultados demonstraram que a época de colheita influenciou as características agronômicas das quatro etnovariedades de mandioca avaliadas. As etnovariedades Cacau roxa e Cacau amarela apresentaram pico de produtividade de raízes tuberosas aos oito e dez meses pós-plantio, respectivamente. Já a Cacau branca e Mandioca pão apresentam-se mais produtivas aos 12 meses, indicando que a permanência das plantas no campo proporcionou incremento na produtividade e diâmetro das raízes, além de maior índice de colheita e, portanto, são boas opções para o agricultor familiar matogrossense.

Published: May 2020

As atividades relacionadas à exploração do petróleo vêm trazendo grande preocupação devido aos riscos de derrames acidentais. Na Província Petrolífera de Urucu vem sendo realizada atividades de exploração e produção de petróleo e gás natural desde 1986. O petróleo de Urucu é transportado dos poços para a planta central através de um oleoduto construído em 1997. Ao longo do tempo o oleoduto pode apresentar desgaste, podendo ocorrer vazamentos e possíveis contaminações no ambiente. O objetivo desta pesquisa foi determinar a existência de microrganismos do solo na rizosfera de plantas ao redor de oleoduto com potencialidade para degradar o petróleo de Urucu caso ocorra algum derramamento. Foram realizadas quatro coletas de campo em duas épocas diferentes, sendo obtidos solos rizosféricos de duas espécies de gramíneas (Brachiaria humidicola, Brachiaria decumbens), uma leguminosa (Mucuna pruriens) e um lacre (Vismia guianensis). A adição de petróleo ao meio de cultura resultou em aumentos significativos de microrganismos capazes de degradar esse complexo orgânico, com as populações de bactérias ultrapassando 4,5x108 UFC.g-1 de solo, fungos filamentosos ultrapassando 1,4x107 UFC.g-1 de solo e leveduras ultrapassando 6,0x107 UFC.g-1 de solo, populações essas, capazes de contribuir para a degradação do petróleo caso ocorra algum derramamento ao longo do oleoduto. Entre as quatro espécies, a Brachiaria decumbens apresentou a maior ocorrência de microrganismos degradadores de petróleo. As maiores concentrações de UFC (Unidades Formadoras de Colônias) de bactérias, fungos filamentosos e leveduras ocorreram no período seco. No período chuvoso, a maior concentração de UFC de bactérias ocorreu em Brachiaria humidicola e, de fungos filamentosos e leveduras em Mucuna prurinens. No período seco, a maior concentração de UFC de bactérias ocorreu em Brachiaria decumbens, de fungos filamentosos em Mucuna pruriens e leveduras em Brachiaria decumbens.

A copirólise (CP) é a quebra de mais de uma biomassa pelo calor em ausência de oxigênio, gerando produtos líquidos, sólidos e gasosos. A constituição do carvão depende das condições de copirólise e do processo adotado. Estudou-se o efeito combinado da temperatura, do fluxo de nitrogênio e composição percentual de lodo de efluente industrial tratado de uma beneficiadora de arroz (LEITBA) com casca de arroz (CA) para geração de carvão por CP através de um planejamento de Box-Behnken (B-B), com percentual de LEITBA variando entre 25 e 75%, temperatura de 500 ºC a 700 ºC e fluxo de N2 de 1 a 5 mL.min-1. Aplicou-se a metodologia de superfície de resposta (MSR) para modelar, analisar e otimizar as condições de CP. O modelo polinomial de primeira ordem explicou o fenômeno de máxima geração de carvão com uma variância explicada superior a 90%. A geração de carvão foi significativamente dependente de duas das três variáveis: percentual de LEITBA e temperatura. A partir do modelo, as ótimas condições para maximizar a geração de carvão foram com temperaturas de 500 ºC e 100% de lodo independente do fluxo de N2. Experimentalmente, observou-se maior geração de carvão a 75% LEITBA, 500 oC e fluxo de N2 de 3 mL.min-1 com 67,09% de biomassa inicial convertida.

Atualmente, o aproveitamento de resíduos na construção civil tem sido estimulado, uma vez que esse setor apresenta como um dos maiores consumidores de materiais naturais em seus processos e produtos. Objetiva-se com esse trabalho avaliar a adição de resíduos de sabugo de milho para a produção do concreto. Fazendo com que o mesmo possa se tornar um grande auxiliador na produção de materiais alternativos de menor custo, substituindo em parte os agregados naturais, normalmente empregados na fabricação de artefatos de concreto. Os resíduos do milho, especificamente o sabugo, foram triturados, peneirados conforme a granulometria da areia, e substituídos no concreto. O traço utilizado foi obtido junto uma tabela de resistência, sofrendo algumas modificações. Foram confeccionados ao mesmo tempo lotes testemunhos e lotes com substituição do agregado miúdo. Este trabalho avaliou o comportamento físico e mecânico do concreto com adição de resíduos de sabugo de milho na proporção de 3% da massa de areia, comparando com o concreto convencional. A substituição do agregado miúdo pelo agregado miúdo reciclado obteve redução nos resultados de resistência média, portanto, não descaracteriza o potencial promissor do resíduo de sabugo de milho como matéria-prima alternativa para uso em concretos não estruturais.

Published: May 2020

Artiklen baseres på det oplæg, som forfatteren gav ved den metropolhistoriske konference på Frederiksberg Rådhus, august 2019. Der tages afsæt i, at grundfortælling om urbaniseringen og dermed by- og boligudviklingens historie er velkendt, og i dansk byhistorie står grundlæggende uantastet. Med dette udgangspunkt illustrerer artiklen, hvordan den herskende forståelsesramme har overlejret kræfter, tendenser og ideer, der i perioder spillede en væsentlige rolle, men som ikke sejrede og derfor ikke blev levnet plads i fortællingen. I fire cases eksemplificeres potentialet i de overlejrede historier og belyses den almindelige parceludstykning, en glemt forening, som viser tilbage til parcelorganisationernes kulturelle tilknytning til de landlige kulturer, forholdet mellem den tidlige almennyttige boligbevægelse og parcellisterne og endelig Mikkel Hindhede, parcelbevægelsen og den teknikerstyrede samfundsudvikling.

Published: May 2020

This present study has discussed the levels and trends of under-five mortality in sub-Sahara Africa. This study aims to estimate under-five mortality using Summary of Birth Histories (SBH) of currently married women which may provide valuable information for assessing the interventions and measures already in place to achieve Sustainable Development Goals (especially goal 3). The Trussell variant which is the modified version of the Brass model was adopted to derive under-five mortality from SBH of currently married women. The result shows that the index for under-five mortality ( ) implied by the north family of the Coale–Demeny model life tables ranges from 65.8 deaths per 1000 live births in Zambia (2018 ZDHS) to as high as 132.9 deaths per 1000 live births in Nigeria (2018 NDHS) respectively. The average estimate of under-five mortality for the countries is about 107.9 deaths per 1000 live births for currently married women and 108.4 deaths per 1000 live births for the entire women in the surveys. While the average probability of a newborn baby surviving to age 5 is about 0.8921 for currently married women that of the entire women is about 0.8915.
Forecasting of Rabi Pulse Production in Odisha (India) by Using Autoregressive Integrated Moving Average (ARIMA) Technique
Authors: Dash Abhiram , Mangaraju A. , . Suman , Mishra Pradeep
Published: May 2020

The present study was carried out to forecast the production of rabi pulse in Odisha by using the forecast values of area and yield of rabi pulses obtained from the selected best fit Autoregressive Integrated Moving Average (ARIMA) model. The data from 1971-72 to 2010-11 are considered as training set data and used for model building and from 2011-12 to 2015-16 are considered as testing set data and used for cross-validation of the selected model on the basis of the absolute percentage error. The ARIMA models are fitted to the stationary data which may be the original data and/or the differenced data. The different ARIMA models are judged on the basis of Autocorrelation Function (ACF) and Partial autocorrelation Function (PACF) at various lags. The possible ARIMA models are selected on the basis of significant coefficient of autoregressive and moving average components. The best fitted models are selected on the basis of residual diagnostics test and model fit statistics. The ARIMA model found to be best fitted for area under rabi pulse and yield of rabi pulse are ARIMA (2,0,0) with constant and ARIMA (0,1,1) without constant respectively which are successfully cross-validated with the testing set data. The excellent fit ARIMA model has been used to forecast the area and yield of rabi pulse for the years 2016-17, 2017-18 and 2018-19. The forecast value of area shows an increase, where as, the forecast values of yield shows a decrease. The forecast values of production of rabi pulse obtained from the forecast values of area and yield of rabi pulse shows an increase which is due to the increase in forecast value of area. Thus emphasis must be laid on increasing the future yield of rabi pulse so as to achieve sufficient increase in production of rabi pulses which could ensure nutritional security to more extent.
The Hypolipidemic Effect of Aqueous Extract of Hibiscus sabdariffa on Paracetamol-induced Hepatotoxicity in Albino Wistar Rats
Authors: Umoren E. B. , Ekpenyong J. F. , Oyama O. E. , Obembe A. O.
Published: May 2020

Aim of the Study: This study was undertaken to ascertain if Hibiscus sabdariffa extract can affect the lipid profile (Total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), very low density lipoprotein (VLDL), and low density lipoprotein (LDL)) levels in a paracetamol- induced hepatotoxicity using albino Wistar rat as a model.

Materials and Methods: Thirty (30) rats used for this study were divided into three groups. Group A (n=10) served as control. Group B (n=10) was administered paracetamol only at a dose of 750 mg/kg body weight. Group C (n=10) was administered paracetamol (dose 750 mg/kg body weight) and aqueous extract of H. sabdariffa (dose 10 ml/kg body weight) of the animal for 3 weeks. All animals were allowed free access to clean drinking water and normal rat chow.

Results: Results of the study revealed that TC was significantly lower (p<0.05) in the paracetamol + H. sabdariffa-treated group as compared to paracetamol-treated group and control respectively. Similar trend was observed with TG, VLDL-c, LDL-c and HDL-c. However, the decrease in HDL-c was not statistically significant when compared to control.

Conclusion: The presence of bioactive constituents vis; anthocyanins, flavonoids, polyvenols and free radical scavenging properties in H. sabdariffa enabled a hypolipidemic effect on the animals by lowering the levels of serum TG, VLDL-c, LDL-c despite challenge on the liver. However, it was unable to produce significant effect on HDL concentration -very important cholesterol required in high level to maintain homeostasis inside the body. This may be due to the challenge on the liver as a result of the paracetamol abuse.

Aims: This study aimed at determining the In-vitro antioxidant capacity, characterise phytochemical constituents, assess toxic and functional properties of African yam bean (Sphenostylis stenocarpa) seed-enriched Cassava product (Pupuru) flour blends using standard methods.

Methodology: Pupuru flour blends were produced from spontaneously-fermented cassava tubers substituted with African yam bean (Sphenostylis stenocarpa) seed (AYBS) (5% (EP5), 10% (EP10) and 15% (EP15), before toasting, cooling, milling, sieving and packaging. A commercial sample (CP) with 100% cassava and another produced in this study, were used as controls.

Results: In-vitro 2,2-Azino-bis (3-ethylbenthiazoline-6-sulphonic acid) (ABTS) and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging abilities, total flavonoid content (TFC), ferric reducing antioxidant power (FRAP) and total phenol content (TPC) increased significantly (P = .05) as AYBS enrichment levels increased. The commercial and laboratory control samples showed no significant difference (P = .05) in all the antioxidants analysed except DPPH: ABTS (7.61- 12.27%); DPPH (26.34-48.26%); TFC (0.10-0.25 mg CAE/g); FRAP (0.81-2.36 (mg/g) and TPC (15.74- 24.15 mg GAE/g). All the phytochemicals except tannins increased significantly (P = .05) as levels of enrichment with AYBS increased. Tannins, phytates, saponins, alkaloids and oxalates were 1.46 -2.87 (mg/g); 0.85-1.40 mg/100 g; 4.18-13.27 mg/g; 24.89-29.05 mg/g and 1.71-3.23 mg/g, respectively. The toxic constituent revealed that all the samples contained significantly different (P = .05) cyanide ranging from 0.87-2.51 mg/kg which reduced as AYBS level of inclusion increased. The functional properties of the samples were significantly (P = .05) enhanced with AYBS enrichment.

Conclusion: Utilisation of AYBS to enrich Pupuru increased its In-vitro antioxidant capacity and phytochemical constituents, reduced the toxic cyanide content enhanced the functional properties, hence, its suitability as a nutraceutical to delay the ageing process and prevent cardiovascular diseases.

Introduction: The minimally invasive approach has become the method of choice for treating most benign abdominal diseases that require surgery. However, it is obvious that laparoscopic procedures are not risk free. The aim of this study was to evaluate the prevalence of intra abdominal adhesions underneath umbilical scar following laparoscopic sterilization, in patients who are undergoing abdominal surgeries.

Materials and Methods: The present study was a hospital based prospective observational study conducted in the Department of Surgery, Dr Rajendra Prasad Government Medical College (Dr. RPGMC), Kangra at Tanda (HP). The study group consisted of patients admitted to department of surgery during a period of one year and who fulfilled inclusion criteria. During intraoperative period, they were examined for presence or absence of adhesions at the site of previous laparoscopic sterilization scar at Periumblical area.

Results: Total of 60 patients were taken in this study. Two out of 60 (3.3%) patients had adhesions underneath previous Laparoscopic Sterilization scar around umbilicus and adhesive structure was omentum in both cases.

Conclusion: Adhesion formation is expected in any abdominal surgery whether open or laparoscopic surgery. In our study only 3.3% of patients had adhesions underneath previous laparoscopic sterilization scar in periumblical region. Therefore umbilical port can be considered for re-entry of index port in next laparoscopic surgery, in patients with history of laparoscopic surgery through umbilical region.

Background and Objective: Unproductive soil has been a major problem to farmers, recent interest in the use of a stable organic manure (biochar) as soil amendment and poultry manure to increase soil fertility is also increasing. Hence, the experiment was conducted to assess the condition of poultry manure and biochar on the growth and yield of tomato.

Materials and Methods: A greenhouse experiment was conducted at the Federal College of Forestry Ibadan, using polyethylene bag with 5 kg soil collected at two (2) soils depths, 0-15 cm and 15-30 cm depth at the botanical garden, Federal College of Forestry Ibadan. The experiment was arranged in a completely randomized design (CRD) with four replicates. The treatments used were poultry manure (5t/ha), biochar (10t/ha), mixture of poultry manure and biochar (1:1) and control (no amendment).The tomato seeds (UC82B) were sourced from NIHORT, Ibadan and raised in a germination basket. Data were collected weekly on plant height, collar diameter and number of leaves, 50% days to flowering and yield of tomato plants from two weeks after transplanting (WAT). Data collected were analyzed statistically using ANOVA while means were separated using LSD (p<0.05) where applicable.

Results: In 0-15 cm soil, the growth variables (plant height, number of leaves and collar diameter) increased with various treatments used. The highest tomato height was observed with the application of biochar (10t/ha). All the treatments applied affected the number of tomato leaves at all weeks after transplanting (WAT) with poultry manure 5t/ha having the highest number of leaves at 7WAT, while collar diameter was significantly affected by various treatments from 2 to 5 WAT, with the mixture of P.M + BIO (1:1) recording the highest value and the control plot recorded the least values in all weeks. However, in 15-30 cm soil, there was  significant difference in the number of leaves of tomato among all the amended soil from 5 to 7 WAT, the highest tomato leaves were obtained when the soil was amended with poultry manure (5t/ha) and can be compared with other treatments. Interaction of poultry manure and biochar(1:1) and poultry manure 5 t/ha resulted in highest height of tomato plant from 3-7 WAT as compared to the control that had the least value but were not significantly different from the sole application of  biochar 10t/ha. Interaction of poultry manure + biochar (1:1) and poultry manure (5t/ha) gave the highest tomato flowering and fruits.

Conclusion: Based on this result, biochar and poultry manure when added to soil, boosted the mineralization of the soil after amendment.

Aim: Natural products play a pivotal role in innovative drug discovery by providing structural leads for the development of new therapeutic agents against various diseases. The present study aims to focus on the in silico assessment of the therapeutic potential of antidiabetic phytoconstituents which were identified and isolated from the extracts of Bauhinia rufescens Lam., a medicinal plant traditionally used for various pharmacotherapeutic purposes.

Methods: The physicochemical and pharmacokinetic parameters of the isolated thirty eight compounds were predicted using Swiss ADME web tool whereas OSIRIS Property Explorer was used for toxicity risk assessment and drug- likeliness. Twelve compounds were selected for docking on human α-glucosidase and α-amylase enzymes using Autodock 4.0 software.

Results and Discussion: Eriodictyol was found to have the highest potential as an inhibitor against α-amylase with binding energy of -9.92 kcal/mol. Rutin was the most potent against α-glucosidase with binding energy of-9.15 kcal/mol. A considerable number of hydrogen bonds and hydrophobic interactions were computed between the compounds and the enzymes thereby making them energetically favorable and suggesting inhibition of these two enzymes as a plausible molecular mechanism for their antidiabetic effect.

Conclusion: These two flavonoids could therefore be used as potential leads for structure- based design of new effective hypoglycemic agents.

Published: May 2020

Este estudo apresenta uma análise do processo de medicalização e patologização da educação em escolas municipais de ensino fundamental de Vitória, Espírito Santo. Tem por principal objetivo conhecer os motivos de encaminhamento para diagnóstico médico de 1.628 alunos matriculados em 45 escolas públicas de ensino fundamental, no ano letivo de 2013. Com esse propósito, foi desenvolvido um estudo documental com abordagem quantiqualitativa. Foi utilizado para análise dos dados o software Statistical Package for the Social Sciences (SPSS), versão 20.0, mediante a estatística descritiva, com tabelas de frequência simples e gráficos com cruzamentos. Foram definidas oito categorias de análise que emergiram dos encaminhamentos realizados, entre as quais duas se destacaram: dificuldade de aprendizagem, perfazendo um total de 67% dos alunos encaminhados; e problema de comportamento, com 54,8%. Os resultados obtidos demonstraram ainda que os alunos encaminhados eram, em sua maioria, do sexo masculino, totalizando 67,6%. A faixa etária predominante se encontrava entre 8 e 10 anos, equivalendo a 41,3% dos alunos encaminhados, seguida da faixa etária entre 11 e 13 anos, que foi 31,6%. Essa faixa etária corresponde ao primeiro ciclo do ensino fundamental, tendo uma porcentagem equivalente a 72,3%, com destaque para os matriculados no segundo e terceiro anos. Constatou-se, ainda, que, desde a idade de 13 anos, os encaminhamentos caem abruptamente. Quanto ao ano escolar, essa queda começa no quinto ano, sendo quase inexistente o número de encaminhamentos realizados no nono ano.
Educação e Pragmatismo: diálogos entre Aníbal Ponce, István Mészáros e Hannah Arendt

Educar para a liberdade e emancipação ou para formar profissionais aptos ao mercado de trabalho? Como a educação cedeu espaço ao pragmatismo e como refletir sobre alternativas a este modelo formativo? Pensar a educação é tarefa complexa e multidimensional, pois sua história não nasceu, tampouco se ampliou, de um movimento uniforme, homogêneo. A depender do lugar no mundo, os processos educacionais apresentaram-se de maneiras diferentes, cujo papel da educação variava a depender dos mandatários ou destinatários deste sistema. Alguns desses processos eram “bem-sucedidos” se considerarmos a minoria a ser alcançada. Quando, posteriormente, a educação atinge as classes trabalhadoras, seu foco é preparar mão de obra para o mercado de trabalho; busca-se exclusivamente um pragmatismo técnico. Nesse sentido, o presente artigo tem como objetivo refletir sobre processos e perspectivas educacionais, através de um diálogo entre os educadores Aníbal Ponce e István Mészáros e a filósofa Hannah Arendt. Dos autores nos utilizaremos para demonstrar como a história da educação inclinou-se, no decorrer dos séculos, ao pragmatismo; da autora, extrairemos uma perspectiva educacional que, acreditamos, surge como alternativa a ser implantada nas práticas daqueles envolvidos nos processos educacionais, cuja principal referência seja o próprio ser humano, ainda em formação. Não se trata, no entanto, de oferecer uma proposta pronta, que pretenda resolver o problema do pragmatismo de maneira completa ou simplista. Trata-se, na verdade, de refletir sobre possíveis caminhos que podem ser trilhados a partir do pensamento arendtiano.

Dimerization of the small GTPase Arf is prerequisite for the scission of COPI‐coated transport vesicles. Here, we quantify the monomer/dimer equilibrium of Arf within the membrane and show that after membrane scission, Arf dimers are restricted to donor membranes. By hydrogen exchange mass spectrometry, we define the interface of activated dimeric Arf within its switch II region. Single amino acid exchanges in this region reduce the propensity of Arf to dimerize. We suggest a mechanism of membrane scission by which the dimeric form of Arf is segregated to the donor membrane. Our data are consistent with the previously reported absence of dimerized Arf in COPI vesicles and could explain the presence of one single scar‐like noncoated region in each COPI vesicle.

The development of advanced catalyst integration strategy is of great importance and promising for long‐term and stable gas catalysis in environmental processing. However, conventional catalyst fabrication techniques including spray method and spin coating cannot overcome the key problems of catalyst peeling off from substrate and related severe performance degradation. In this work, an in situ integration strategy of monolithic Au/TiO2 catalysts on Ti mesh for efficient and stable low‐temperature CO oxidation is reported. Plasma electrolytic oxidation technology can create a porous TiO2 seeding layer with strong substrate adherence. Subsequent hydrothermal reaction, ion exchange, and calcination processes can induce the in situ nucleation of sodium titanate nanosheets and their follow‐up conversion to TiO2 nanosheets with huge surface area. The oxygen defects generated in anatase TiO2 nanosheet supports can not only provide sufficient anchoring sites for the deposition and attachment of gold nanoparticles (Au NPs) during deposition–precipitation process, but also absorb and activate oxygen species. Meanwhile, the strong interactions between Au NPs and TiO2 support make the catalysts more chemically active. As a result, the Au/TiO2 monolithic catalysts can eliminate CO completely at low temperature and exhibit considerably high stability, suggesting their potential in practical applications.

The iodine(III) reagents vinylbenziodoxolones (VBX) were employed to vinylate a series of aliphatic and aromatic thiols, providing E‐alkenyl sulfides with complete chemo‐ and regioselectivity, as well as excellent stereoselectivity. The methodology displays high functional group tolerance and proceeds under mild and transition metal‐free conditions without the need for excess substrate or reagents. Mercaptothiazoles could be vinylated under modified conditions, resulting in opposite stereoselectivity compared to previous reactions with vinyliodonium salts. Novel VBX reagents with substituted benziodoxolone cores were prepared, and improved reactivity was discovered with a dimethyl‐substituted core.

The assembly of atomically precise metal nanoclusters offers exciting opportunities to gain fundamental insights into the hierarchical assembly of nanoparticles. However, it is still challenging to control the assembly of individual nanoclusters at a molecular or atomic level. Herein, we report the dimeric assembly of Au25(PET)18 (PET=2‐phenylethanethiol), where two Au25(PET)18 monomers are bridged together by two Ag atoms to form the Ag2Au50(PET)36 dimer. The Ag2Au50(PET)36 dimer is a unique mesomer, which has not been found in any other chiral metal nanoclusters. Furthermore, the Ag2Au50(PET)36 dimer is distinct from the Au25(PET)18 monomer in its optical, electronic, and catalytic properties. This study is expected to provide a feasible strategy to precisely modulate the assembly of metal nanoclusters with controllable structures and properties.
