El clorhidrato de clembuterol (CCL) es un b-agonista promotor del crecimiento en animales para abasto, pero su uso ilícito ha generado repercusiones en salud pública. Se realizó un modelo biológico con ratones, con el objeto de evaluar el efecto del CCL sobre la ganancia de peso y las lesiones histológicas que ocasiona. Los ratones fueron alimentados con carne de conejo, que previamente fue suplementada con CCL. Treinta y cinco días posexposición se registró el peso corporal; se obtuvo la concentración muscular y sérica de CCL a través de la prueba de ELISA, y se colectaron tejidos (hígado y corazón) para análisis histopatológico. Los valores obtenidos de los animales experimentales (G1 y G2) se analizaron mediante un diseño experimental completamente al azar con dos tratamientos (n = 10), sometidos a un análisis de varianza y comparación de medias con la prueba de Tukey (p < 0,05). Se registró un incremento de peso corporal de 7 g en el G1, contra 4,0 g del G2. El peso del hígado fue de 2,58 g y 1,79, respectivamente (p < 0,05). En el G1 la concentración muscular de CCL fue 5324 pg g–1 y en suero sanguíneo de 4378 pg g–1. Solo se observaron cambios histológicos en tejidos de los ratones del G1. El hígado mostró tumefacción celular, mitosis moderada, picnosis y degeneración hidrópica; en corazón, engrosamiento de fibras, pleomorfismo e hileración nuclear. El CCL favoreció el incremento de peso en los ratones expuestos, y provocó alteraciones estructurales en hígado y corazón.

Authors: Restrepo Betancur Giovanni , Rojano Benjamín Alberto
Published: January 2018

Una amplia variedad de antioxidantes evaluados en la congelación de semen equino no ha arrojado resultados satisfactorios en el mantenimiento de su calidad y fertilidad. El isoespintanol y el timol son moléculas de origen natural con una alta actividad antioxidante, lo que las hace potencialmente útiles para reducir el estrés oxidativo del semen durante la criopreservación. Este estudio tuvo como objetivo evaluar el efecto del isoespintanol y el timol en la actividad antioxidante total y enzimática de semen equino diluido con fines de congelación. El semen de cinco caballos criollos colombianos se diluyó en un medio de congelación, se dividió en tres alícuotas que se asignaron aleatoriamente a los tratamientos isoespintanol (40 μM), timol (50 μM) o control (sin antioxidante). Se evaluó la capacidad antioxidante total (TAC) por los ensayos ORAC y FRAP. La actividad de catalasa (CAT), superóxido dismutasa (SOD) y glutatión peroxidasa (GPx) se evaluaron mediante pruebas enzimáticas. La evaluación estadística se realizó mediante modelos mixtos, análisis de correlación y comparación de medias por la prueba de Tukey. Las actividades de SOD y GPx fueron menores para el isoespintanol (6,7 ± 2,2 U/ ml y 0,16 ± 0,02 U/ml), comparadas con el timol (6,9 ± 2,2 U/ml y 0,20 ± 0,02 U/ml) y el control (7,2 ± 2,2 U/ml y 0,22 ± 0,02 U/ml) (p < 0,05). No hubo diferencias para la TAC o la CAT del semen (p > 0,05). El isoespintanol reduce la actividad de SOD y GPx en el semen equino diluido con fines de congelación.

A Entrega Vigiada de Vítimas no Tráfico Internacional de Pessoas: Investigação Policial e Dignidade da Pessoa Humana
Authors: Dornelas Luciano Ferreira , Machado Bruno Amaral
Published: January 2018

A “entrega vigiada” no tráfico e contrabando internacional de pessoas, prevista na Convenção de Palermo, traz evidente conflito em relação à dignidade humana em face da discricionariedade da autoridade policial. O presente artigo tem por objetivo analisar, diante do permissivo da “entrega vigiada” de vítimas, prevista no Protocolo Adicional à Convenção de Palermo, em que medida é necessário que as autoridades permitam o risco à integridade física e/ou sexual de uma ou de algumas vítimas de tráfico e contrabando de pessoas em prol da obtenção de provas ou do melhor momento que justifique o retardamento da ação para o alcance de uma condenação substancial dos envolvidos ou que abranja maior número de delinquentes. Questiona-se se a integridade física e a dignidade sexual das vítimas submetidas à “entrega vigiada” têm recebido primazia em prol da pretensão de colheita da prova. Argumenta-se, ao final, que as autoridades, ao se utilizarem da “entrega vigiada” de vítimas, têm negligenciado a segurança e a dignidade da pessoa em prol da obtenção da prova, não provendo mecanismos efetivos que assegurem a integridade física e moral da pessoa humana durante as investigações de tráfico e contrabando de pessoase
A Eutanásia e a “Morte Digna” em Portugal-UE, Brasil, Bem como na Ásia Oriental: Japão, China e Coreia do Sul – Direito Penal e Criminologia (Direitos Fundamentais)
Authors: Bandeira Gonçalo S. de Melo
Published: January 2018

a eutanásia é um problema que se discute muito atualmente. O presente artigo compara a eutanásia e a “morte digna” na Lusofonia com a Ásia Oriental. Na parte lusófona, o artigo analisa Portugal em profundidade e o Brasil, brevitatis causa, apenas nos pontos essenciais. Faremos também breves referências a outros países europeus e ao Estado do Vaticano, cuja doutrina influenciou profundamente a cultura Ocidental. Na Ásia Oriental, o artigo analisa o Japão, a China e a Coreia do Sul. Em todos os ordenamentos jurídicos podemos encontrar problemas doutrinários, jurisprudenciais e legislativos. Mas uma vez que a eutanásia é uma questão de vida e morte de seres humanos, esses problemas legais estão intimamente conexionados com problemas também éticos e morais. Questões de dignididade do ser humano têm importância fundamental no mundo inteiro. Assim, a eutanásia e a “morte digna” não são só debatidas no Ocidente, mas também são questões importantes no Extremo Oriente.

Authors: Sanches Raquel Cristina Ferraroni , Sponchiado Viviane Boacnin Yoneda
Published: January 2018

O presente artigo trata do uso do inquérito policial eletrônico na investigação de crimes que envolvem violência doméstica e familiar contra as mulheres. Justifica-se a pesquisa pela constante evolução tecnológica de nossa sociedade e também pela evolução percorrida pela própria definição de família, que se tornou mais ampla e abrangente, alargando, inclusive, a gama de crimes que envolvem as relações domésticas e familiares. Diante de um ramo tão especializado de investigação policial, indaga-se se a adesão às práticas investigativas modernas e inovadoras auxiliaria nos trabalhos das Delegacias de Polícia de Defesa da Mulher, dentre elas, o uso do inquérito policial eletrônico. Em um primeiro momento, serão discutidos quais crimes envolvem violência doméstica e familiar contra as mulheres. A seguir, será discutido o uso do inquérito policial eletrônico, de maneira geral, e nas particularidades da investigação dos crimes domésticos. A pesquisa pauta-se pelo método dedutivo e utilizou doutrinas, jurisprudências e legislações pertinentes ao tema.
Excesso de Litigância e Demandas Repetitivas: um Desafio para o Judiciário Brasileiro
Authors: Correa Priscilla P. Costa , Moraes Vânila Cardoso André
Published: January 2018

O objetivo destes escritos é apontar o atual estado de excesso de litigância no Judiciário Brasileiro, colocando-se em evidência o fenômeno das demandas repetitivas. Constata-se que ao reiterar lesões individuais, o Poder Público, os prestadores de serviços públicos e de serviços de massa geram um uso abusivo e predatório do Judiciário brasileiro, alimentando morosidade, ineficiência, falta de efetividade, o que, compromete o acesso à justiça e contribui para a desigualdade no país. Analisa-se as reformas recém promovidas, e conclui-se que estas iniciativas não serão capazes de solucionar o problema das demandas repetitivas. Defende-se a releitura do princípio constitucional da inafastabilidade da jurisdição para que dele se extraia a ideia de subsidiariedade da via jurisdicional, como forma de fortalecimento da cidadania e rompimento com a arraigada cultura de judicialização de conflitos. Destaca-se a inexistência de instrumentos processuais adequados e de uma base principiológica vocacionada à solução de demandas repetitivas. Propõe-se a criação de um Centro de Inteligência que interligue as diversas instâncias do Judiciário brasileiro, identifique e analise as causas da judicialização excessiva de demandas repetitivas, e promova um efetivo Monitoramento da formação das lides com este perfil, buscando-se soluções coletivas, preferencialmente pré-processuais e consensuais, a partir do fortalecimento do diálogo Interinstitucional. Defende-se a adoção do conceito multiportas, promovendo-se o direcionamento dos conflitos aos métodos mais adequados de pacificação como forma de valorização da cidadania, procedimentalização da isonomia, prevenção de demandas repetitivas, e, por conseguinte, melhor distribuição de justiça no país.

La Regulación del Intermediario Inmobiliario: su Evolución y Actual Alcance Normativo, el Ejemplo Catalán
Authors: Balaguer Elena Palomares
Published: January 2018

La figura de los intermediarios inmobiliarios surgió de manera necesaria por la complejidad de las operaciones llevadas a cabo, tanto legal como económicamente. La necesaria adquisición de los inmuebles mediante operaciones bancarias complejas, en la mayoría de los casos hipotecas contratadas por consumidores con conocimientos escasos o nulos de economía; unido a los entresijos legislativos y a la intervención de notario y registrador, hicieron necesaria la especialización de determinados agentes que actuaban en el mercado. Pero esta necesaria especialización ha ido acompañada siempre de conflicto, provocado por el enorme valor económico de la propia operación. La intervención de la administración, regulando y evitando un monopolio de la misma, justifica el continuo cambio legislativo que, por otro lado, ha creado en ocasiones una gran inseguridad. En las siguientes líneas veremos cómo ha evolucionado dicha regulación y cómo influye en la figura del intermediario.
A Teoria da Imprevisão e o Equilíbrio Econômico-Financeiro do Contrato Administrativo: Leitura a Partir do Garantismo Jurídico
Authors: Menezes Vitor Hugo Mota de , Teixeira Heloysa Simonetti , Silvio Solange Holanda Almeida
Published: January 2018

O tema versado neste artigo tem por escopo analisar a teoria da imprevisão como instrumento hábil a assegurar o direito à proteção do equilíbrio econômico-financeiro contratual, sob a perspectiva garantista, haja vista o dever de estrita observância aos princípios da equidade e da segurança jurídica nas relações jurídicas bilaterais. Nesse sentido, verifica-se que, conquanto os pactos imponham a obrigatoriedade de cumprimento das obrigações assumidas – pacta sunt servanda –, a ocorrência de fatos supervenientes e estranhos à vontade dos contratantes não pode submeter as partes a sacrifício que as leve à ruína, ou seja, há de se considerar o denominado humanismo do contrato. Busca-se, assim, identificar a conexão entre a teoria do garantismo e a previsão constitucional de se manter intangível a equação econômico-financeira do contrato, de modo a obter a efetivação dos princípios constitucionais que lhe dão suporte. Nesse prisma, a presente pesquisa se preordena para, inicialmente, tratar acerca da teoria da imprevisão, a partir da cláusula rebus sic stantibus, expondo breve histórico de seu surgimento e, passo subsequente, identificar sua caracterização, interconectando-a aos princípios da equidade e da segurança jurídica, como efetivação dos preceitos constitucionais, aos quais as partes têm dever de vassalagem, sob a ótica da teoria garantista, no sentido substancial. Por fim, a pesquisa intenta demonstrar a importância da harmonização das relações intersubjetivas no contrato administrativo, em consonância com a Constituição, centro irradiador de normas e princípios aos microssistemas jurídicos que compõem todo o ordenamento jurídico. A metodologia empregada para elaboração do artigo é analítica, bibliográfica e crítica.
El Recurso al Art. 10.2 CE como Paradigma de los dos Tribunales Constitucionales
Authors: Fernández Itziar Gómez
Published: January 2018

En los últimos años la jurisprudencia constitucional española apunta la existencia de dos visiones en torno a la posición del art. 10.2 CE en la interpretación de los derechos fundamentales. Una recurre al precepto para justificar los límites al goce y ejercicio de los derechos humanos. La otra considera que el art. 10.2 CE confiere al intérprete una base mínima sobre la que se puede, o incluso se debe, aumentar el nivel de protección de los derechos. Y la finalidad del estudio es poner de manifiesto el alcance y los argumentos desarrollados por una y otra posición. El punto de partida del estudio se basa en la presentación de dos sentencias básicas, la STC 155/2009 y la STC 198/2012, ambas particularmente “abiertas” al derecho internacional, para describir posteriormente la problemática específica del lugar de la Carta de Derechos Fundamentales en el ordenamiento jurídico español a través del artículo 10.2, que denota una cierta reticencia a la apertura constitucional y presentar, por fin, una serie de sentencias, sobre temas diversos que destacan la tensión existente dentro del tribunal a la hora de recurrir al art. 10.2 CE como criterio hermenéutico.

Authors: Gonçalves Carla Ferreira , Oliveira Joaquim Humberto Coelho de
Published: January 2018

O surgimento e a implementação de novas tecnologias de informação e comunicação, mudaram a forma com que o indivíduo se relaciona com os demais no meio social. As relações interpessoais revolucionaram numa velocidade vertiginosa nas últimas quatro décadas. O advento da Internet foi fator determinante para a configuração dos novos paradigmas de relacionamento. Cada pessoa é capaz de se posicionar diante de bilhões de outras pessoas, sem que precise, se locomover. Como o próprio nome implica, as tecnologias de informação e comunicação permitem que pessoas, conectadas entre si, compartilhem, criem e discutam novos conhecimentos. Nesse cenário de hiperconectividade surgiram as redes sociais virtuais, que funcionaram como catalisador para a revolução das formas de relacionamento. A revolução tecnológica valorizou a comunicação e possibilitou a conversação e interação entre pessoas a distância seja ela restrita a duas pessoas ou a um grupo de pessoas determinadas. As redes sociais digitais tornaram-se ambientes propícios à infidelidade virtual. O presente trabalho tem como objetivo verificar a possibilidade de configuração de dano decorrentes da violação do dever de fidelidade recíproca e a reparação civil.

Ce travail recompose la situation de la ainsi nommée "fin des avantgardes", afin d’analyser la dernière étape de l’oeuvre poétique de Haroldo de Campos. La lecture de recueils tels que A educação dos cinco sentidos, Crisantempo, A máquina do mundo repensada et Entremilênios permet d’envisager le tournant "post-utopique" chez Campos, en dialogue avec son oeuvre critique, comme une modalité de rapport avec le contemporain en tant qu’époque de "crise", et avec le poète en tant que porteur de son message.
O lúdico e o ensino de Geociências no Brasil: principais tendências das publicações na área de Ciências da Natureza
Authors: Teixeira Danilo Missias , Machado Fábio Braz , Silva Josilaine Santina da
Published: January 2018

As atividades lúdicas são metodologias de ensino que vêm conquistando espaço no Ensino de Ciências; proporcionam um estudo dos conceitos de forma mais dinâmica e prazerosa. Todavia, quando se trata dos conceitos de Geociências as dificuldades apresentadas pelos professores de Ciências Exatas e Biológicas acabam por fazer com que estes profissionais não elaborem propostas vinculadas a tais conceitos. O objetivo deste trabalho é, portanto, identificar na literatura científica do Ensino de Ciências as principais tendências de pesquisas com características lúdicas que possuam como foco os conceitos de Geociências. Para isso, foi realizada uma busca em: (a) banco de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), e (b) periódicos vinculados ao Ensino de Ciências. Como resultado, foi possível observar que as publicações lúdicas no Ensino de Ciências apresentam as seguintes tendências: (1) A maior parte das publicações tem origem na região Sudeste, principalmente nos estados de Rio de Janeiro e São Paulo; (2) O número de publicações é crescente a partir do ano de 2014, com ponto forte no ano 2016; (3) a maior área de conhecimento a apresentar trabalhos é Química, seguida de Biologia; (4) as publicações são, em sua maior parte, experiências realizadas no Ensino Médio, e (5) a modalidade lúdica preferencial é “Jogo Didático”.
Heresy in the Siberian way: publishing activities of non-traditional religions, sects, dogma in Siberia and the Far East (90s of the XX - 10s of the XXI centuries)
Authors: Posadskov A. L.
Published: January 2018

Since the early 1990s non-traditional religions were widespread in Siberia and the Far East, and across Russia, among which there was a large number of totalitarian sects and destructive cults. The reason for the phenomenal success of previously unknown religious and occult teachings has been the spiritual vacuum that occurred in the country after the Communist ideology fall. Most of the new denominations launched in Russia publishing, which by the second decade of the XXI century was carried on by several dozen communal or sectarian publishers. In Siberia and the Far East the most active sects in publishing were the following: Protestant Church of Christ, Baha'i Faith followers, Krishna consciousness regional societies (in particular, the residents of Vladivostok), «Pleiadinas» sects («Ascended Masters» teachings). These sectarian creeds nave been brought into the country, however, and nowadays pseudo-religious cults are created in Russia, which carry a large destructive potential for the Russian society and its cultural traditions. They are Neo-pagans, the Marian center and a number of sects, whose activities began in Siberia: All-Russian movement «To God’s Rule!», The Church of the Last Testament of Vissarion Christ, etc. These cults had in Siberia and the Far East extensive publishing practices editing books, brochures, magazines, newspapers. «Pleiadinas» sect organized in Siberia edition of the monthly magazine «World Channeling» (Novokuznetsk), created two publishing houses: «Star of Freedom» (Novosibirsk) and «SiriuS» (Omsk). The Marian center used printing district offices of Kemerovo region for its production activity. Neo-pagans had publishing houses «Asgard’», «Arcor» and «Russian Truth» in Omsk. The article analyzes all these publishing organizations’ products. The ruinous effects of sectarian publishing activities distribution in the Russian regions is obvious. Its effect reduction will depend on the speed of eliminating the crisis in the spiritual sphere of our society.

Mitigating Challenges of Open Government Data
Authors: Dvir Nim
Published: January 2018

The Release of government dataset for public use can potentially strengthen the relationship between the government and its constituents. However, research shows that there are several challenges for open data effectiveness. This paper reviews current determinants and issues associated with the open government data (OGD) procedures. The review concentrates on two ends of the spectrum: First, from the perspective of the preparation by the government, focusing on the organization of traditional governmental datasets and how the recording of the data is administered. Second, from the perspective of the users, focusing on the way in which the data is released to the general public and on human-computer interaction (HCI) issues between end-user and data-consumption interfaces. Following a thorough analysis of these two opposing challenges, the paper proposes approaches to mitigate them. This review and subsequent recommendations contribute and expand current understanding of open government data effectiveness and can lead to public policy changes, development of new procedures and strategies, and ultimately improvements at both ends of the federal open data endeavor.
Potential of New Isolates of Dunaliella salina for Natural β-Carotene Production
Authors: Xu Yanan , Ibrahim Iskander M. , Wosu Chiziezi I. , Ben-Amotz Ami , Harvey Patricia J.
Published: January 2018

The halotolerant microalga Dunaliella salina has been widely studied for natural β-carotene production. This work shows biochemical characterization of three newly isolated Dunaliella salina strains DF15, DF17 and DF40 compared with D. salina CCAP 19/30 (confirmed to be D. tertiolecta) and D. salina UTEX 2538 (also known as D. bardawil). Although all three new strains have been genetically characterized as Dunaliella salina strains, their ability to accumulate carotenoids and their capacity for photoprotection against high light stress are different. DF15 and UTEX 2538 reveal great potential for producing large amount of β-carotene and maintained a high rate of photosynthesis under light of high intensity; however, DF17, DF40 and CCAP 19/30 showed increasing photoinhibition with increasing light intensity, and reduced contents of carotenoids, in particular b-carotene, suggesting that the capacity of photoprotection is dependent on the cellular content of carotenoids, in particular β-carotene. Strong positive correlations were found between the cellular content of each of all-trans β-carotene, 9-cis β-carotene, all-trans α-carotene and zeaxanthin but not lutein in the D. salina strains. Lutein was strongly correlated with respiration in photosynthetic cells and strongly related to photosynthesis, chlorophyll and respiration, suggesting an important and not hitherto identified role for lutein in co-ordinated control of the cellular functions of photosynthesis and respiration in response to changes in light conditions, which is broadly conserved in Dunaliella strains. Statistical analysis based on biochemical data revealed a different grouping strategy from the genetic classification of the strains. The significance of these data for strain selection for commercial carotenoid production is discussed.
Comparative Studies on Thermal, Mechanical, and Flame Retardant Properties of PBT Nanocomposites with Functionalized Amino-Carbon Nanotubes Modified by Different Oxidation State Phosphorus-containing Agents

Published: January 2018

High-performance poly(1,4-butylene terephthalate (PBT) nanocomposites have been developed via the consideration of phosphorus-containing agents and amino-carbon nanotube (A-CNT). One-pot functionalization method has been adopted to prepare functionalized CNTs via the reaction between A-CNT and different oxidation state phosphorus-containing agents, including chlorodiphenylphosphine (DPP-Cl), diphenylphosphinic chloride (DPP(O)-Cl), and diphenyl phosphoryl chloride (DPP(O3)-Cl). These functionalized CNTs, DPP(Ox)-A-CNTs (x = 0, 1, 3), were respectively mixed with PBT to obtain the CNTs-based polymer nanocomposites through a melt blending method. SEM observations demonstrated that DPP(Ox)-A-CNT nano-additives were homogeneously distributed within PBT matrix compared to A-CNT. The incorporation of DPP(Ox)-A-CNT improved the thermal stability of PBT. Moreover, PBT/DPP(O3)-A-CNT showed the highest crystallization temperature and tensile strength, due to the superior dispersion and interfacial interactions between DPP(O3)-A-CNT and PBT. PBT/DPP(O)-A-CNT exhibited the best flame retardancy resulting from the excellent carbonization effect. The radicals generated from decomposed polymer were effectively trapped by DPP(O)-A-CNT, leading to the reduction of heat release rate, smoke production rate, carbon dioxide and carbon monoxide release during cone calorimeter tests.
Thermal and Mechanical Characterization of EMA-TEGDMA Mixtures for Cosmetic Applications
Authors: Donoso Ruben , Reina José Antonio , Giamberini Marta , De La Flor Silvia , Ferrando Francesc , Cerruti Pierfrancesco
Published: January 2018

Mixtures of methacrylic polymers are the most common materials for making composites to be used as resins for dental and cosmetic applications. Some of these mixtures are composed by poly (ethyl methacrylate) (PEMA) and poly (methyl methacrylate) (PMMA), which constitute a solid component to be mixed with a liquid component made out of methacrylate monomers. The reaction between the thermal initiator benzoyl peroxyde (BPO) present in the solid component and the activator of the polymerization process, N,N-dimethyl-p-toluidine (DMT) present in the liquid component, gives rise to thermoset materials. In the present study, different liquid formulations composed by a mixture of two methacrylic monomers, ethyl methacrylate (EMA) and triethylene glycol dimethacrylate (TEGDMA) for cosmetic applications, were prepared and characterized, using a commercial powder (POW) composed by PEMA and PMMA. With the aim of improving workability during final application of the material, it was necessary to slow down the polymerization rate of liquid formulations. Their thermal behaviour was investigated by DSC in order to check the polymerization rate. Thermal stability of final materials was determined by TGA. DMTA, microindentation hardness and impact tests were performed on final materials, to assess their performance with respect to standard formulation. The combination of thermal and mechanical properties allows choosing which formulations could be suitable for use in cosmetics.
Mn4+-Doped Magnesium Titanate—A Promising Phosphor for Self-Referenced Optical Temperature Sensing
Authors: Venturini Francesca , Baumgartner Michael , Borisov Sergey M.
Published: January 2018

Phosphors based on magnesium titanate activated with Mn4+ ions are of great interest because, when excited with blue light, they display a strong red-emitting luminescence. They are characterized by a luminescence decay which is strongly temperature dependent in the range from 0 to 80 °C, making these materials very promising for temperature sensing in the biochemical field. In this work the optical and thermal properties of the luminescence of Mg2TiO4 are investigated for different Mn4+ doping concentrations. The potential of this material for temperature sensing is demonstrated by fabricating a fiber optic temperature microsensor and by comparing its performance against a standard resistance thermometer. The response of the fiber optic sensor is exceptionally fast, enabling monitoring of temperature fluctuation in subsecond time domain.
Travelling Surface Plasmons with Interference Envelope and A Vision for Time Crystals
Authors: Djalalian-Assl Amir
Published: January 2018

The influence of the film thickness and the substrate’s refractive index on the surface mode at the superstrate is an important study step that may help clearing some of the misunderstandings surrounding their propagation mechanism. A single sub-wavelength slit perforating a thin metallic film is among the simplest nanostructure capable of launching Surface Plasmon Polaritons on its surrounding surface when excited by an incident field. Here, the impact of the substrate and the film thickness on surface waves is investigated. When the thickness of the film is comparable to its skin depth, SPP waves from the substrate penetrate the film and emerge from the superstrate, creating a superposition of two SPP waves, that leads to a beat interference envelope with well defined loci which are the function of both the drive frequency and the dielectric constant of the substrate/superstrate. As the film thickness is reduced to the SPP’s penetration depth, surface waves from optically denser dielectric/metal interface would dominate, leading to volume plasmons that propagate inside the film at optical frequencies. Interference of periodic volume charge density with the incident field over the film creates charge bundles that are periodic in space and time.

Impacts of Urbanization of Mountainous Areas on Resources and Environment: Based on Ecological Footprint Model
Authors: Ding Yu , Peng Jian
Published: January 2018

The rapid urbanization has exerted tremendous pressure on natural systems in mountains. As a measure of sustainable use of natural resources, ecological footprint is an important basis for judging whether the development of a country or region is within the biocapacity. Taking Dali Bai Autonomous Prefecture as an example, this study comprehensively analyzes the impact of human activities on mountain resources and environment from the three aspects of urbanization, land use and ecological carrying capacity. The results show that Dali Prefecture with the urbanization rate of 33% is still in the accelerated stage of urbanization. The urban space presents the core-periphery feature, and the central city is the focus of human existence and living activities. The per capita ecological footprint is 1.14 hm2/person higher than the ecological carrying capacity, meaning Dali Prefecture is in an ecological deficit state. This indicates that there is an uncoordinated state between urbanization and environment. Arable land is the main source of per capita ecological footprint in the prefecture. However, the urban expansion overly occupies the arable land in the plain sub-region, leading the arable land to an ecological deficit state. In the future, the development of the mountainous area should focus on the protection of arable land and choose a new sustainable path.

In the past two decades, Vitamin K has been receiving more attention due to its role in bone health and metabolism. The bone mineral density does not remain steady with age, particularly declining after menopause.

Objective:

This study is aimed to investigate the relationship between bone mineral density and serum vitamin K1 levels in post-menopausal women, and to evaluate serum vitamin K1 levels as a potential biomarker for postmenopausal osteoporosis.

Methods:

Serum levels of vitamin k1 were measured in 23 postmenopausal osteoporotic women, and in 15 postmenopausal healthy control women using a standardized Enzyme-Linked Immune Sorbent Assay (ELISA) kit. Bone mineral density BMD was assessed at the lumbar spine.

Results:

The mean serum vitamin k1 level was significantly lower in the postmenopausal osteoporotic women group than in the normal control group (mean=0.794 vs3.61ng/ml, P< 0.0001), and serum vitamin k1 concentration was positively correlated with lumbar spine BMD among postmenopausal osteoporotic women (R=0.533, p = 0.009), and in postmenopausal healthy control (R=0.563, p = 0.02).

Diagnostic sensitivity and specificity of vitamin k1 for osteoporosis were 90% and 98%, respectively (cut-off value: 0.853 ng/ml). The area under the ROC curve (AUC) value for vitamin k1 was 0.984 the odd ratio result was 18.66.

Conclusion:

Our results suggest that vitamin K1 may contribute to maintain bone mineral density. Vitamin K1 may have a role in diagnosing post-menopausal osteoporosis. Vitamin K1 may be a valuable diagnostic as well as therapeutic marker in post-menopausal osteoporosis.

Authors: Shahi Mohammad Vafaee , Noorbakhsh Samileh , Zarrabi Vida , Nourozi Banafsheh , Tahernia Leila
Published: January 2018

Background:

Any mismatch between the production and absorption of CSF results in hydrocephalus. In most cases, the selected choice of treatment is the ventriculoperitoneal shunt insertion. Although, the surgery could have complications such as infection, shunt malfunction, subdural hematoma, seizure and Shunt immigration; so, the early and proper detection of these complications could result in better prognosis. The aim of this study was to evaluate and compare the efficacy of CT scan, CSF analysis and X-ray radiography in detection of shunt complications and problems in shunt placement and further follow-up in hospitalized children.

Methods:

The medical records of children in Rasul Akram hospital in Tehran were reviewed retrospectively in the last 10 years, from 2006 to 2016. All data were recorded in the prepared form including the age, sex, shunt complication, CT scan and CSF characteristics.

Results:

The total number of 95 patients were interfered in this study including 56 males (58.9%) and 39 females (41.1%). The mean age at the onset of complications were 2.8±2.2 years-old. The shunt obstruction (60%) and infection (25.3%) were the most common complications. The CT scan was able to detect 36.5% of shunt complications. The CT scan had the sensitivity and specificity of 50 and 87%, respectively in detection of shunt obstruction. The all cases of brain hematoma and hemorrhage were revealed by CT scan. On the other hand, the CT scan had 20% of sensitivity and 60% of specificity in the detection of shunt infection. The CSF evaluation in shunt infection revealed 92% hypoglycemia, 87.5% pleocytosis, and 62.5% positive CSF culture. CSF had the sensitivity, specificity, positive predictive value and negative predictive value of 92, 82, 63 and 97%, respectively. The patient's symptoms and signs were helpful in obtaining higher test accuracy.

Conclusion:

The CT scan was not a good sensitive and specific study in the detection of shunt obstruction and infection, but it was very accurate in detection of hemorrhage and hematoma. On the other hand, CSF evaluation was a reliable test in shunt infection disclosure.

Published: January 2018

BACKGROUND

The prevalence rates of depressive and anxiety disorders are high in residential aged care settings. Older adults in such settings might be prone to these disorders because of losses associated with transitioning to residential care, uncertainty about the future, as well as a decline in personal autonomy, health, and cognition. Cognitive behavioral therapy (CBT) is efficacious in treating late-life depression and anxiety. However, there remains a dearth of studies examining CBT in residential settings compared with community settings. Typically, older adults living in residential settings have higher care needs than those living in the community. To date, no systematic reviews have been conducted on the content and the delivery characteristics of CBT for older adults living in residential aged care settings.

OBJECTIVE

The objective of this paper is to describe the systematic review protocol on the characteristics of CBT for depression and/or anxiety for older adults living in residential aged care settings.

METHODS

This protocol was developed in compliance with the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Studies that fulfill the inclusion criteria will be identified by systematically searching relevant electronic databases, reference lists, and citation indexes. In addition, the PRISMA flowchart will be used to record the selection process. A pilot-tested data collection form will be used to extract and record data from the included studies. Two reviewers will be involved in screening the titles and abstracts of retrieved records, screening the full text of potentially relevant reports, and extracting data. Then, the delivery and content characteristics of different CBT programs of the included studies, where available, will be summarized in a table. Furthermore, the Downs and Black checklist will be used to assess the methodological quality of the included studies.

RESULTS

Systematic searches will commence in May 2018, and data extraction is expected to commence in July 2018. Data analyses and writing will happen in October 2018.

CONCLUSIONS

In this section, the limitations of the systematic review will be outlined. Clinical implications for treating late-life depression and/or anxiety, and implications for residential care facilities will be discussed.
