Entre mitos y realidades: ciudades mexicanas que concentran clase creativa
Authors: Sobrino Jaime
Published: May 2017

El propósito del presente documento consiste en realizar un estudio exploratorio sobre los atributos demográficos y económicos de las ciudades de México en donde se concentra la clase creativa, es decir, aquel segmento de la oferta ocupacional en el mercado urbano de trabajo que se compone por profesionistas, profesores universitarios, investigadores, trabajadores del arte, espectáculos y deportes. El término clase creativa fue propuesto por Richard Florida (2002), y a este segmento de la población ocupada se le ha dado una connotación de ventaja competitiva para la ciudad en donde reside, de tal manera que se ha tratado de comprobar la relación entre el desempeño económico local y la presencia de dicha clase. Aquí no se utiliza a la clase creativa como variable explicativa del comportamiento económico local. Más bien se busca aportar elementos sobre las características de las ciudades con mayor intensidad de clase creativa en su estructura ocupacional. Para alcanzar el propósito se realiza un modelo de regresión logística multivariada. Los resultados permiten concluir que las ciudades donde se concentraba la clase creativa en 2010 eran preferentemente capitales estatales y/o con baja participación de la producción manufacturera en su estructura económica. Asimismo, los ocupados en la clase creativa tuvieron mayor tasa de migración interna con respecto a la población ocupada total. Los lugares de origen y destino de la migración creativa fueron ciudades especializadas, ambas en este tipo de ocupados.

Entre ellos se destacan: a) una especificación preliminar del formato Redatam, b) la publicación de una herramienta para la exportación de bases de datos Redatam y c) la evidencia respecto de que, contrariando lo establecido en la documentación técnica, el software no implementa estrategias de compresión y de encriptación de los microdatos por él almacenados.
Variación espacial de la unión conyugal de los jóvenes en México
Authors: Martínez Salgado Mario , Tapia McClung Rodrigo
Published: May 2017

La unión conyugal es un eje organizador de la vida de las personas y de una sociedad. En México este evento es clave en el proceso de transición a la vida adulta. En muchos casos articula la salida del hogar y el inicio de la reproducción. Se sabe que en el ámbito nacional su temporalidad se ha postergado, pero poco se sabe sobre ella a nivel subnacional. En esta investigación se analiza la variación espacial de la proporción de jóvenes unidos conyugalmente. Se busca identificar la manera como influyen la desigualdad regional y la heterogeneidad cultural sobre la asunción de los roles adultos.

Authors: Santos Harlon Romariz Rabelo , Gonçalves Danyelle Nilin
Published: May 2017

A proposta de Ensino Médio Integrado está relacionada a recentes contextos de política educacional, mais especificamente a movimentos que ressignificam políticas de educação profissional e técnica de nível médio, caminhando no sentido de considerar a educação vocacional como um direito educativo e dever do Estado. Este artigo objetiva contextualizar o modelo do Ensino Médio Integrado nos seus âmbitos de proposta e discussão nacional e relacionar tal contexto à política cearense de Escolas Estaduais de Educação Profissional. A abordagem se dá a partir de análise documental e bibliográfica, levantando dados sobre a política como proposta e seus argumentos, que enfatizam uma suposta necessidade de uma formação teórica integrada à prática e que afirmam o trabalho como princípio educativo; e, em termos da prática cearense: uma construção do modelo das Escolas Estaduais de Educação Profissional como política de desenvolvimento de capital humano, como política de juventude e modelo para todo o ensino médio.

Authors: Mattos Andreza Batista , Fiamenghi-Júnior Geraldo Antônio , Carvalho Sueli Galego de , Blascovi-Assis Silvana Maria
Published: May 2017

As transformações ocorridas no sistema educacional brasileiro têm produzido resultados positivos e negativos no processo inclusivo escolar dos alunos com necessidades educacionais especiais. Este trabalho teve como objetivo identificar as ações de inclusão social na percepção dos educadores de crianças com deficiências múltiplas em escolas de ensino regular no interior de Minas Gerais. Os participantes foram professores de cinco crianças com deficiências múltiplas. Adotou-se uma abordagem qualitativa, de caráter descritivo, utilizando entrevistas semiestruturadas com os professores, além de observações das crianças, realizadas em sala de aula e nos momentos recreativos. Nos depoimentos dos professores, identificou-se que eles não possuem experiência com crianças deficientes e que há necessidade de apoio em sala de aula visando atender às necessidades educacionais especiais dessas crianças, que vivem, em alguns casos, uma exclusão social na situação escolar.
O cânone literário e sua relação com a educação na contemporaneidade
Authors: Röhrig Maiquel
Published: May 2017

Este artigo reflete sobre a formação do cânone da literatura brasileira e sobre as implicações da ausência de um cânone da literatura brasileira contemporânea. Os objetivos são apontar os valores políticos que determinaram a formação do cânone e mostrar a necessidade de trabalhar com os estudantes obras contemporâneas, em detrimento das canônicas, a fim de formar um público leitor por meio da efetiva leitura de obras literárias que, de início, reflitam os conteúdos e a linguagem dos jovens atuais. Este artigo opõe-se à ideia de que se vive atualmente uma crise da literatura, defendendo a tese de que, ao contrário, a literatura brasileira passa por um momento de grande produtividade e qualidade, o que é acompanhado por um incremento de publicações para um público leitor ávido por novas e complexas histórias.
Quel goût donne-t-on a la vie? Alimentation et soin en addictologie
Authors: Lopes Dina , Franco Renata da Rocha Campos , Levivier Marc
Published: May 2017

Partant du constat qu’une alimentation énergétiquement dense (gras/sucré) semblait être privilégiée par un public souffrant d’addiction, ce travail a pour but d’explorer la question de l’alimentation dans le soin en addictologie. En utilisant un questionnaire, créé pour cette enquête, ce travail propose de comparer les habitudes et les préférences alimentaires d’un groupe de 54 hommes divisé en trois populations; chacune ayant une problématique addictive spécifique (nulle/stabilisée/sévère). Les résultats confirment les hypothèses que plus un patient-usager serait acteur de sa prise en charge, moins il favoriserait une alimentation riche en calories et dense, et plus il favoriserait une alimentation équilibrée. Plus la problématique addictive serait critique, plus la consommation d’aliments sucrés/gras serait privilégiée. Plus l’alimentation serait variée et diverse, moins l’addiction chez le patient-usager serait prégnante.

Published: May 2017

Este texto apresenta resultados da pesquisa em torno da história da Escola Polivalente na cidade de Ituiutaba, Minas Gerais, no período que abrange os anos entre 1974 e 1985. Investigam-se os processos históricos que marcaram essa sociedade, a vida dos partícipes das vivências desse âmbito escolar, valorizando a memória da instituição, além de gerar novos conhecimentos para o campo da história da educação do país e da região em foco. As Escolas Polivalentes surgiram em contexto da Ditadura Civil-Militar, tendo como principal característica estabelecerem novos parâmetros para a implantação do modelo tecnicista educacional do regime, o qual se baseou nas relações entre o Brasil e os Estados Unidos. Metodologicamente o estudo se pautou por pesquisas bibliográfica, documental e iconográfica, além de entrevistas com atores que participaram das vivências e experiências dessa instituição.
Do método e do modo: as atitudes profissionais a serem privilegiadas no ensino
Authors: Gauthier Clermont
Published: May 2017

À première vue, les travaux de recherche sur la gestion de la classe sont assez récents; ils datent d’une quarantaine d’années environ. Un examen plus approfondi fait toutefois apparaître des préoccupations pédagogiques similaires, sans toutefois porter ce nom de gestion de classe. L’ouvrage des Frères des écoles chrétiennes, Les douze vertus d’un bon maître, publié en 1785, est exemplaire à cet égard. On y recense dans le menu détail tout ce que le doit maître doit faire et éviter quand il fait la classe. Nombre de ces stratégies de gestion de classe sont identiques à celles proposées par des auteurs contemporains. Plus encore, dans ce relevé systématique des bonnes pratiques pédagogiques, apparaît une forme d’ambiguïté, un “juste assez”, un “ni trop, ni trop peu” qui indique qu’à travers la méthode, il y a la manière, que la façon de faire est plus que la chose faite. C’est sans doute là que réside le fondement de l’attitude professionnelle en enseignement.

Apontamentos sobre as origens históricas do sindicato dos professores de Osasco, Cotia, Carapicuíba e Barueri (SINPROSASCO) em tempos de transição democrática (1985)
Authors: Bauer Carlos , Oliveira Maria Crisneilândia Bandeira
Published: May 2017

O artigo preconiza resgatar alguns aspectos da história do Sindicato dos Professores de Osasco, Cotia, Carapicuíba e Barueri, valendo-se de fontes primárias orais e bibliográficas pertinentes à temática estudada, ao passo que fotografias, atas, panfletos, jornais e demais documentos impressos sindicais são escassos. O referido sindicato nasceu na cidade paulista de Osasco, em 1985, em um período histórico e político de grande importância para a sociedade brasileira, marcado pelo esgotamento da ditadura militar, pelo processo de transição democrática e pela reforma constitucional. No que diz respeito às questões educacionais, as décadas de 1970 e 1980 trouxeram novas formulações nas políticas públicas e a expansão do ensino privado no Brasil, mas também, no auge do então chamado “novo sindicalismo”, os trabalhadores pertencentes às distintas categorias profissionais foram às ruas reivindicar o restabelecimento das eleições diretas e o fim do bipartidarismo, em suma, a redemocratização do país.
A educação ambiental na formação de professores de química da UFBA
Authors: Pinheiro Bárbara Carine Soares , Santos Camila Lima , Peneluc Magno da Conceição
Published: May 2017

O trabalho foi realizado através dos princípios básicos de uma abordagem qualitativa de pesquisa utilizando entrevistas semiestruturadas, com o intuito de investigar como os estudantes concluintes do curso de licenciatura em Química da Universidade Federal da Bahia compreendem o papel da educação ambiental na sociedade. Foram realizadas entrevistas com os discentes concluintes do curso e, a partir dos resultados obtidos, foi possível a criação de categorias para as principais concepções dos licenciandos sobre o tema e avaliação das possíveis interferências dessas em uma prática da educação ambiental crítica. Diante das avaliações, é possível inferir que parte dos graduandos ainda não apresenta uma visão crítica acerca do papel da Educação Ambiental na sociedade, sendo necessária uma reflexão acerca da relevância da Educação Ambiental Transformadora na formação inicial de professores.
Circulação de sentidos da prática como componente curricular na licenciatura em Ciências biológicas
Authors: Barbosa Alessandro Tomaz , Cassiani Suzani
Published: May 2017

Este artigo tem por finalidade compreender a circulação de sentidos sobre a Prática como Componente Curricular num curso de licenciatura em Ciências Biológicas. Para a construção do corpus de análise, realizou-se um levantamento documental e a aplicação de questionários e entrevistas com oito professores desse curso. Como referencial teórico e metodológico, adotou-se a Análise de Discurso francesa, que tem aportes na obra de Michel Pêcheux. Os resultados sinalizam que a circulação de sentido referente à prática como componente curricular não caminha em linha reta, ou seja, a transformação da modalidade escrita desse termo para a modalidade prática no curso de licenciatura em Ciências Biológicas se assenta na tensão entre processos parafrásticos e polissêmicos.
A educação dos alunos das escolas pantaneiras na perspectiva da educação centrada no aluno
Authors: Gonçalves Young Shim , Nogueira Eliane Greice Davanço
Published: May 2017

O presente artigo tem como objetivo desvelar a percepção dos sujeitos sobre uma escola pantaneira. Para tanto, a pesquisa valeu-se, como metodologia, da produção de narrativas (auto)biográficas de três sujeitos, dois alunos e uma mãe de aluno de uma escola localizada na área rural do município de Aquidauana, Mato Grosso do Sul, analisadas a partir dos pressupostos da abordagem (auto)biográfica e da psicologia humanista, que propõe a educação centrada no aluno. Como resultados, constatou-se a falta de especificidade do ensino proposto na escola pantaneira, não diferenciado do que é proporcionado nas escolas urbanas, assim como a presença de um ideário que confere à educação escolar a possibilidade de mobilidade social, associada aos esforços pessoais dos sujeitos, em uma visão meritocrática. Conclui-se que, no contexto investigado, não se efetiva a educação centrada no aluno, o que poderia contribuir para uma educação significativa, emancipatória e transformadora.
Exigências para o exercício do ofício de mestre nos grupos escolares no Brasil no contexto da ditadura militar
Authors: Corrêa Paulo Sérgio de Almeida , Barreto Brianna Souza
Published: May 2017

Analisou-se a configuração do exercício do ofício de mestre nos grupos escolares no período da ditadura militar brasileira. Constituiu-se como finalidade: averiguar as exigências que eram postas ao exercício do ofício de mestre nos grupos escolares no Brasil no contexto da ditadura militar. Adotou-se como método de investigação a pesquisa historiográfica, com uso de fontes bibliográficas. Sob quais exigências institucionais era exercido o ofício de mestre no interior dos grupos escolares no Brasil após o ano de 1964? O ofício de mestre era exercido por alguém que dominasse um saber específico, uma herança histórica, materializada em um fazer que não podia ser realizado por pessoas sem a devida qualificação. Logo, acompanhava o docente para além da escola, visto que ele carrega consigo a imagem de educador construída socialmente, assim como os deveres de sua função como preparação e inquietações que vão além do ambiente escolar.
Education and equalityde: bunking the myth of meritocracy
Authors: Themelis Spyros
Published: May 2017

This article explores how in the postwar years education was constructed as the main way in which a meritocratic society could be created in Britain (but also elsewhere). The concept of meritocracy, that is to say of a just society in which equality of opportunities and education for all, would ostensibly provide the basis with which labor market allocation would be realized. As this article argues, nothing in education operates outside the wider political economy, which in capitalism is inherently unequal as it is underpinned by the existence of antagonistically opposed social classes, separated from each other by unequal access to the means of production. As such, the circulation in the British social system that occurred in the early postwar years was not the result of decreasing inequalities within the class structure but rather the product of the occupational restructuring that fostered high rates of structural mobility. Consequently, “ascription” rather than “ability” continued to facilitate labor market stratification.

Tourism development and economic and socio-cultural consequences in Everest Region
Authors: Rai Dhyanendra Bahadur
Published: May 2017

Being a mountainous country, Nepal is one of the destinations of tourist. Everest Region is one of the major destination trekking and mountaineering tourism and ranks second after Annapurna Region in term of number of tourists visiting different regions of Nepal. The number of tourist visiting this region increased from only 1406 in 1971/72 to 37124 in 2014. Such a growth of tourism has several socio-economic and cultural consequences. This paper discusses the consequences of tourism in Everest Region. Informations were collected along the trekking routes from Lukla to Dinboche through focus group discussion, key informant interview and tourism business survey. The results indicate that the number of hotels and lodges in many settlements along the trekking route has increased tremendously. The main base of economic life of Sherpa community has been changed from agro-pastoralism to tourism based business. The level of employment and income of local people has improved. However, tourism has undermined Sherpa culture by introducing new values and lifestyles influencing from westerners, eroded the central role of religion and traditional value in Sherpa community. For the younger generation the tourist and their norms of behavior and patterns of consumption can be seductive. This is the symptom of losing of cultural value of Sherpa community and world identity of Sherpa in the future.The Geographical Journal of Nepal Vol. 10: 89-104, 2017
Gender development perspective: A contemporary review in global and Nepalese context
Authors: Baral Balkrishna
Published: May 2017

For the empowerment of women several international meetings, conferences and seminars have been taking place globally. Consequently, women are becoming stronger in social, economic, and political sectors. The numbers of women state heads have revealed that internationally women are being empowered politically. Women’s struggle in Nepal has also brought a remarkable change in establishing women rights in social, economic, and political spheres. After democratic restoration, few efforts have been made for their empowerment. Still the Human Development index of women is not so encouraging. However, they have been involved in multi sectoral activities such as household economy, environmental conservation, social functions, and infrastructure development. After 1990, political parties have involved women in their political organizations and have provided opportunities to be elected and nominated in the national legislature, executive and judiciary. Few of them have already got chances to be Minister and Member of Parliament.Similarly, women have been working as District Development or Village Development Committee chairperson. In the inaccessible remote areas still they are not much empowered and their involvement is less. It is necessary to make them empowered.
Park-people interaction - Its impact on livelihood and adaptive measures: A case study of Shivapur VDC, Bardiya District, Nepal
Authors: Paudyal Narayan Prasad
Published: May 2017

This paper deals with the concept of theoretical and conceptual framework in a research with park-people interaction of Bardiya National Park (BNP) with specific reference to Shivapur Village Development Committee (VDC) of Bardiya district. The local people enter the park illegally and exploit the park resources like fodder, firewood, thatch, etc. They also try to kill wildlife either for food as traditional profession or for money. They frequently encounter with wildlife and get injured; sometimes they are killed. Similarly, wildlife cross the park boundary and destroy the crops and kill the livestock. Villagers also get their shelters and sheds damaged by them. BNP, therefore, has introduced various programmes to keep the conservation intact without disturbing the livelihood of Buffer Zone people. Several efforts, such as construction of Trench, Machan etc. have been made to address the issues associated with park people conflicts. In addition, endowment funds, such as Rahat Kosh, Apatkalin Kosh and Chetipurti Kosh have been established to provide and compensate to the human casualty and property (mainly building) damage.The Park-People interaction is the reality and the need is felt from both sides. Despite ups (harmony) and downs (conflicts) and despite differential use of resources by localities, the interface continues and is likely to continue so long as both these entities exist there. The need is to realize each-others limitations and strengthen their mutual understanding and the benefits.The Geographical Journal of Nepal Vol. 10: 167-180, 2017

An Attitude Determination Method for Comprehensive Inspection Vehicle Based on Track Profile Registration
Authors: Zhang Yumei , Zhang Dalin
Published: May 2017

The attitude of the comprehensive inspection vehicle is one of the important factors that affect the accuracy of the inspection of metro line infrastructure, meanwhile the metro environment restricts the employment of common attitude determination methods. A new method of attitude determination is presented in this paper, which takes the track as reference and employs non-contact measurement to acquire the track profile simulta-neously. By registration of measurement track profile and the standard track profile, the relative position between the vehicle and the track reference can be calculated; and the instantaneous attitude of the vehicle can be determined by the matrix inverse calculation. The performance of the method is verified by an experiment using the road-rail comprehensive inspection vehicle.
A Comparison of Ordered and Unordered Response Models for Analyzing Road Traffic Injury Severities in the North-Eastern Turkey
Authors: Çelik Ali Kemal , Oktay Erkan
Published: May 2017

Road traffic injuries are estimated to be one of the major causes of death worldwide and a majority of them occur in low- and middle income countries. In that respect, further studies that address to determine risk factors that may influence road traffic injury severities in the corresponding countries may contribute the existing road safety literature. This paper determines possible risk factors influencing road traffic injury severity in north-eastern Turkey. For this purpose, a retrospective cross-sectional study is conducted analysing 11,771 traffic accidents reported by the police during the sample period of 2008-2013. As the accident severity is inherently ordered, the data are analysed using both ordered and unordered response models. The estimation results reveal that several driver (age and education level), accident (speeding violation, avoiding manoeuvre and right-of-way rule), vehicle (bus/minivan, single-unit truck/heavy truck, private and single vehicles), temporal (time of day, morning peak, evening peak), environmental (summer and cloudy or rainy weather), geometry (asphalt road and road class type), and control characteristics (presence of crosswalk and traffic lights) were found to have an impact on injury severity. This paper is most probably the first attempt to analyse possible risk factors of road traffic injury severities in Turkey using both ordered and unordered response models. The evidence of this study may be valuable for future road safety policies in emerging countries.
The Significance of New Records of Benthic Red Algae (Rhodophyta) for Hainan Island (and China) between 1990 and 2016
Authors: Titlyanova Tamara , Titlyanov Eduard , Li Xiubao , Bartsch Inka , Xia Bangmei
Published: May 2017

We present an annotated list of new finds of red algae from Hainan Island, Southern China, including those found in 1990 and 1992 during the German-Chinese expeditions to Hainan Island and in 2008–2016 by Titlyanova, Titlyanov, and Li. Between 1990 and 1992, a total of 64 taxa of red algae were newly recorded for Hainan Island. Of these 15 species were new records for China. During the period 2008–2016, a further 54 taxa were newly recorded for Hainan Island, of which 20 were new records for China. The full list of new taxa includes taxonomic forms, dates, and locales, together with known biogeographical distributions. During both periods, the apparent enrichment of red algal marine flora has occurred in a similar way—mainly at the expense of epiphytes with filamentous, thin-filamentous, and finely branched forms. We believe that the changes in the flora of Hainan Island have been influenced by both anthropogenic and natural factors including in particular exploitation of herbivores, nutrient pollution, and coral bleaching.
Plant Debris and Its Contribution to Ecosystem Carbon Storage in Successional Larix gmelinii Forests in Northeastern China

Published: May 2017

Plant debris, including woody debris and litter, is an essential but frequently overlooked component of carbon (C) storage in forest ecosystems. Here, we examined the C storage of plant debris and its contribution to total ecosystem C storage in an age sequence of six larch (Larix gmelinii) forest stands (15, 36, 45, 54, 65, and 138 years old) in northeastern China. The plant debris C storage increased from 6.0 ± 0.5 Mg·C·ha−1 in the 15-year-old stand to a maximum of 9.3 ± 1.8 Mg·C·ha−1 in the 138-year-old stand. The C storage of woody debris increased during stand development in a sigmoidal pattern, increasing from 0.7 ± 0.2 Mg·C·ha−1 in the 15-year-old stand to 4.7 ± 1.3 Mg·C·ha−1 in the 138-year-old stand. However, the C storage of litter (4.6−5.4 Mg·C·ha−1) did not vary with stand age in this larch chronosequence. In addition, the ratio of woody debris to live tree biomass C storage was relatively stable across stands (approximately 3.3%). These results highlight the importance of considering successional development and stand characteristics in assessing changes of plant debris and total ecosystem C storage in the larch forest ecosystem
EZH2 in Cancer Progression and Potential Application in Cancer Therapy: A Friend or Foe?

Published: May 2017

Enhancer of zeste homolog 2 (EZH2), a histone methyltransferase, catalyzes tri-methylation of histone H3 at Lys 27 (H3K27me3) to regulate gene expression through epigenetic machinery. EZH2 functions as a double-facet molecule in regulation of gene expression via repression or activation mechanisms, depending on the different cellular contexts. EZH2 interacts with both histone and non-histone proteins to modulate diverse physiological functions including cancer progression and malignancy. In this review article, we focused on the updated information regarding microRNAs (miRNAs) and long non coding RNAs (lncRNAs) in regulation of EZH2, the oncogenic and tumor suppressive roles of EZH2 in cancer progression and malignancy, as well as current pre-clinical and clinical trials of EZH2 inhibitors.
Annual Atmospheric Corrosion of Carbon Steel Worldwide. An Integration of ISOCORRAG, ICP/UNECE and MICAT Databases
Authors: Chico Belén , De la Fuente Daniel , Díaz Iván , Simancas Joaquín , Morcillo Manuel
Published: May 2017

In the 1980s, three ambitious international programmes on atmospheric corrosion (ISOCORRAG, ICP/UNECE and MICAT), involving the participation of a total of 38 countries on four continents, Europe, America, Asia and Oceania, were launched. Though each programme has its own particular characteristics, the similarity of the basic methodologies used makes it possible to integrate the databases obtained in each case. This paper addresses such an integration with the aim of establishing simple universal damage functions (DF) between first year carbon steel corrosion in the different atmospheres and available environmental variables, both meteorological (temperature (T), relative humidity (RH), precipitation (P), and time of wetness (TOW)) and pollution (SO2 and NaCl). In the statistical processing of the data, it has been chosen to differentiate between marine atmospheres and those in which the chloride deposition rate is insignificant (<3 mg/m2.d). In the DF established for non-marine atmospheres a great influence of the SO2 content in the atmosphere was seen, as well as lesser effects by the meteorological parameters of RH and T. Both NaCl and SO2 pollutants, in that order, are seen to be the most influential variables in marine atmospheres, along with a smaller impact of TOW.

The wide abuse of antibiotics has accelerated bacterial multiresistance, which means there is a need to develop tools for rapid detection and characterization of bacterial response to antibiotics in the management of infections. In the study, an electrochemical biosensor based on nanoporous alumina membrane and graphene quantum dots (GQDs) was developed for bacterial response to antibiotics detection. Anti-Salmonella antibody was conjugated with amino-modified GQDs by glutaraldehyde and immobilized on silanized nanoporous alumina membranes for Salmonella bacteria capture. The impedance signals across nanoporous membranes could monitor the capture of bacteria on nanoporous membranes as well as bacterial response to antibiotics. This nanoporous membrane and GQD-based electrochemical biosensor achieved rapid detection of bacterial response to antibiotics within 30 min, and the detection limit could reach the pM level. It was capable of investigating the response of bacteria exposed to antibiotics much more rapidly and conveniently than traditional tools. The capability of studying the dynamic effects of antibiotics on bacteria has potential applications in the field of monitoring disease therapy, detecting comprehensive food safety hazards and even life in hostile environment.

Accelerating emergence of antimicrobial resistance among food pathogens and consumers’ increasing demands for preservative-free foods are two contemporary challenging aspects within the food industry. Antimicrobial packaging and the use of natural preservatives are promising solutions. In the present study, we used beta-casein—one of the primary self-assembly proteins in milk with a high polymeric film production capability—as a fusion partner for the recombinant expression of E 50-52 antimicrobial peptide in Escherichia coli. The pET21a-BCN-E 50-52 construct was transformed to E. coli BL21 (DE3), and protein expression was induced under optimized conditions. Purified protein obtained from nickel affinity chromatography was refolded under optimized dialysis circumstances and concentrated to 1600 µg/mL fusion protein by ultrafiltration. Antimicrobial activities of recombinant BCN-E 50-52 performed against Escherichia coli, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, Aspergillus flavus, and Candida albicans. Subsequently, the synergistic effects of BCN-E 50-52 and thymol were assayed. Results of checkerboard tests showed strong synergistic activity between two compounds. Time–kill and growth kinetic studies indicated a sharp reduction of cell viability during the first period of exposure, and SEM (scanning electron microscope) results validated the severe destructive effects of BCN E 50-52 and thymol in combination on bacterial cells.

The effect of four mercapto flavor compounds (1,2-ethanedithiol, 1-butanethiol, 2-methyl-3-furanthiol, and 2-furanmethanethiol) on acrylamide elimination were investigated in model systems. The obtained results showed that mercaptans assayed were effective in elimination arylamide in a model system. Their reactivities for decreasing acrylamide content depended on mercaptan’s molecular structure and acrylamide disappearance decreased in the following order: 1,2-ethanedithiol > 2-methyl-3-furanthiol > 1-butanethiol > 2-furanmethanethiol. Mercaptans were added to acrylamide to produce the corresponding 3-(alkylthio) propionamides. This reaction was irreversible and only trace amounts of acrylamide were formed by thermal heating of 3-(alkylthio) propanamide. Although a large amount disappeared, only part of the acrylamide conversed into 3-(alkylthio) propionamides. All of these results constitute a fundamental proof of the complexity of the reactions involved in the removal of free acrylamide in foods. This implies mercapto flavor/aroma may directly or indirectly reduce the level of acrylamide in food processing. This study could be regarded as a pioneer contribution on acrylamide elimination in a model system by the addition of mercapto flavor compounds.

Herbgenomics provides a global platform to explore the genetics and biology of herbs on the genome level. Panax ginseng C.A. Meyer is an important medicinal plant with numerous pharmaceutical effects. Previous reports mainly discussed the transcriptome of ginseng at the organ level. However, based on mass spectrometry imaging analyses, the ginsenosides varied among different tissues. In this work, ginseng root was separated into three tissues—periderm, cortex and stele—each for five duplicates. The chemical analysis and transcriptome analysis were conducted simultaneously. Gene-encoding enzymes involved in ginsenosides biosynthesis and modification were studied based on gene and molecule data. Eight widely-used ginsenosides were distributed unevenly in ginseng roots. A total of 182,881 unigenes were assembled with an N50 contig size of 1374 bp. About 21,000 of these unigenes were positively correlated with the content of ginsenosides. Additionally, we identified 192 transcripts encoding enzymes involved in two triterpenoid biosynthesis pathways and 290 transcripts encoding UDP-glycosyltransferases (UGTs). Of these UGTs, 195 UGTs (67.2%) were more highly expressed in the periderm, and that seven UGTs and one UGT were specifically expressed in the periderm and stele, respectively. This genetic resource will help to improve the interpretation on complex mechanisms of ginsenosides biosynthesis, accumulation, and transportation.

7a-(Methoxycarbonyl)-N-methyl-1,3a,5,6,7,7a-hexahydro-4H-1,4,6-(epiethane[1,1,2]triyl)indene-4,9-dicarboximide has been prepared through a modification of a previous synthetic sequence, in which the benzyloxymethyl hydroxyl protecting group has been replaced by methoxymethyl, to avoid the apparent formation of a benzyl ester derivative as a side product. The overall yield of the new synthetic sequence is comparable to the previous one. Two advantages of the new procedure are: (a) no benzyl ester was formed and (b) a stereoisomeric mixture of syn- and anti-alcohols at the beginning of the synthetic sequence could be separated and the rest of the synthesis could be carried out with the main syn-stereoisomer instead of the corresponding stereoisomeric mixture as it was the case in the previous process. Additionally, several functional 2,8-ethanonoradamantane derivatives have been prepared.

Published: May 2017

Lysophospholipids (LPLs) are the most abundant polar lipids in wheat endosperm and naturally complex with amylose, affecting starch physicochemical properties. We analyzed LPLs in wheat flour from 58 cultivars which differ by grain hardness using liquid chromatography mass spectrometry (LCMS). There were significant differences in LPL content between cultivars, demonstrating that genotype rather than environment contributes most to the total variance in wheat endosperm LPLs. Polar lipids such as LPLs may play a role in grain hardness through their interaction with puroindoline proteins, however, no strong correlation between kernel hardness and LPLs was detected. This may reflect the location of LPLs within the starch granule as opposed to the puroindoline proteins outside starch granules. LPLs may have an indirect relationship with kernel hardness as they could share the same origin as polar lipids that interact with puroindoline on the starch granule surface.

Diterpenoids are considered the major active compounds in Tinospora sinensis in virtue of their special structures and activities. Herein, an analytical method was developed for rapid screening and identification of diterpenoids in T. sinensis using high-performmance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry (HPLC-LTQ-Orbitrap) in negative ion mode. Two diterpenoid reference standards were first analyzed to obtain their characteristic ESI-MS/MS fragmentation patterns. Then, based on the extracted ion chromatogram (EIC) data-mining method and characteristic fragmentation pathways analysis, diterpenoids in T. sinensis were rapidly screened and identified. After that, an important parameter, Clog P, was adopted to discriminate between the isomers of diterpenoids. As a result, 63 diterpenoids were characterized from the extract of T. sinensis, including 10 diterpenoids and 53 diterpenoid glycosides. Among them, 15 compounds were tentatively identified as new compounds. Finally, target isolation of one diterpenoid glycoside named tinosineside A was performed based on the obtained results, which further confirmed the deduced fragmentation patterns and identified diterpenoid profile in T. sinensis. The results demonstrated that the established method could be a rapid, effective analytical tool for screening and characterization of diterpenoids in the complex systems of natural medicines.

The global demand for energy is increasing and the detrimental consequences of rising greenhouse gas emissions, global warming and environmental degradation present major challenges. Solar energy offers a clean and viable renewable energy source with the potential to alleviate the detrimental consequences normally associated with fossil fuel-based energy generation. However, there are two inherent problems associated with conventional solar thermal energy conversion systems. The first involves low thermal conductivity values of heat transfer fluids, and the second involves the poor optical properties of many absorbers and their coating. Hence, there is an imperative need to improve both thermal and optical properties of current solar conversion systems. Direct solar thermal absorption collectors incorporating a nanofluid offers the opportunity to achieve significant improvements in both optical and thermal performance. Since nanofluids offer much greater heat absorbing and heat transfer properties compared to traditional working fluids. The review summarizes current research in this innovative field. It discusses direct solar absorber collectors and methods for improving their performance. This is followed by a discussion of the various types of nanofluids available and the synthesis techniques used to manufacture them. In closing, a brief discussion of nanofluid property modelling is also presented.
