The circular and linear structure of political values and the three stereotypes about the left, center and right
Authors: Maj Przemysław
Published: July 2020

The aim of the article is to give arguments against the presence of three stereotypes in political science concerning leftism, centrism and rightism. The first one involves the classification of political entities by indicating their place on the left-centre-right axis. The second is based on the belief that leftism, centrism and rightism can be narrowed down to specific levels of competition (e.g. views on the economy or religion). The third stereotype is “dogma” that the conflict over political values was initiated during the French Revolution. The author explains his position with reference to the psychological theory of Shalom H. Schwartz and the circular matrix of meta-value.

Authors: Rachwał Marcin
Published: July 2020

The article addresses the issue of voter turnout at the national level in Poland in 1990–2019. In particular, the author focused on 2019, when the turnout in parliamentary elections was the highest throughout the period under analysis. The aim of the study is to determine the reasons for this increase in the electoral activity of Polish citizens. The analysis leads to the conclusion that after the Law and Justice party took power in 2015, significant modifications of the social system, including the political system, ensued, thereby altering selected features of the electoral situation and raising the level of political emotions. The outcome involved a significant increase in voter turnout in 2019, when the elections to the European Parliament, as well as to the Polish parliament (the Sejm and Senate) were held. The study employs the following methods: analysis and criticism of literature (sources), the systemic method, and statistical methods.

Pandemia ocasionada pelo novo Coronavírus: sistema de saúde e medidas de enfrentamento na Turquia / Pandemic caused by the new coronavirus: health system and coping measures in Turkey
Authors: Aydogdu Ana Luiza Ferreira
Published: July 2020

Objetivo: contextualizar o sistema de saúde da Turquia e o enfrentamento à pandemia de doença pelo novo coronavírus. Método: trata-se de um estudo teórico, exploratório baseado na leitura, análise e interpretação de textos científicos, leis e informações de sites oficiais do governo turco sobre o novo coronavírus. Resultados: o governo turco sempre informou sobre a importância do isolamento social. Entretanto, uma parte da população não atendeu aos apelos feitos, por isso foram aprovadas leis visando restringir à circulação das pessoas. No momento, o aumento no número de casos e óbitos vem mantendo uma média e as restrições estão sendo reduzidas. Conclusões: testes rápidos são feitos em todos os suspeitos de contágio e o tratamento é gratuito nas instituições públicas, que estão bem equipadas. A população em geral e os profissionais de saúde precisam receber maior apoio por parte do governo.
ESTUDO SOBRE IDENTIFICAÇÃO HUMANA POR DNA, BANCO NACIONAL DE PERFIS GENÉTICOS E A OBRIGATORIEDADE DA LEI 12654/2012
Authors: Brito Ana Flávia , Pontes A.N.
Published: July 2020

Estudar a investigação criminal por identificação humana por DNA é pertinente, pois essa tecnologia tem a capacidade de identificar o indivíduo por meio de sua “impressão”. Esta técnica ligada às ferramentas científicas/tecnológicas pode ser de grande ajuda no meio civil e criminal. Para tanto, foi criado o Banco Nacional de Perfis Genéticos (BNPG) que necessita das contribuições da Rede Integrada de Banco de Perfis Genéticos espalhadas por quase todo o país, em que laboratórios “alimentam” o banco fornecendo materiais biológicos de pessoas desparecidas, suspeitas de algum crime e condenados criminalmente. O BNPG contém armazenados pouco mais de 10 mil amostras, o que não condiz com o real número esperado de um país com altos índices de homicídios e a 3ª maior população carcerária do mundo, em que apenas 5% dos homicídios são elucidados e apenas 3,5% de DNA de presos foram coletados desde a implantação da Lei nº 12.654 de 2012. Assim, este trabalho teve por objetivo realizar um estudo sobre identificação humana por DNA, BNPG, sua Rede Integrada e a obrigatoriedade da doação de material genético de condenados segundo a Lei nº 12.654 que prevê a coleta de DNA de condenados. A pesquisa foi bibliográfica e documental, com variáveis quali-quantitativa. Os dados apresentados demonstram que os bancos de perfis genéticos são uma valiosa ferramenta de investigação criminal e segurança pública, que ainda está sendo subtilizada no sistema de justiça brasileiro.
Prevalência de álcool e drogas em mortes por afogamento no Rio Grande do Sul
Authors: Torres Carine , Arbo Marcelo Dutra
Published: July 2020

O afogamento é a terceira causa mais frequente de mortes por traumatismo não intencional no mundo e sabe-se que, aproximadamente, 2 bilhões de pessoas no mundo consomem bebidas alcoólicas. Diante dessa problemática, o presente estudo visou avaliar a prevalência de álcool e drogas em vítimas de afogamento no Rio Grande do Sul no ano de 2015. Dados de afogamento e de análises toxicológicas sobre álcool, drogas e fármacos foram obtidos a partir do banco de dados do Departamento Médico Legal de Porto Alegre. Foram analisados 213 casos de afogamento e o álcool esteve presente em 37,55% dos casos, já fármacos e drogas ilícitas em 12,6%. O perfil epidemiológico aponta jovens do sexo masculino como principais vítimas de afogamento. A prevalência de álcool, drogas e fármacos pode ter contribuído para mortes por afogamento. Dessa forma, campanhas de prevenção e educação poderiam resultar na redução dos índices de afogamento.
Como o esforço do perito de local, em SC, e o BNPG levaram à solução de um homicídio no PR após 10 anos sem suspeitos
Authors: Penna Odicsan E. M. V. e R.
Published: July 2020

Apesar dos esforços dos estados em manter recursos humanos adequados, é cada vez maior a discrepância na relação entre a quantidade de Peritos Criminais e a quantidade de crimes ocorridos no Brasil[1]. O Banco Nacional de Perfis Genéticos (BNPG) é uma ferramenta que permite diminuir este desequilíbrio, viabilizando a determinação de autores tanto em crimes em investigação, quanto nos casos “frios” (sem suspeitos de autoria). Este artigo apresenta o exemplo de conduta de um Perito de Local que, mesmo sem requisição, vislumbrou a importância da coleta de material biológico no hospital, de uma menina estuprada e jogada em um trem para morrer em Santa Catarina. Este procedimento, além de culminar na confirmação e condenação do autor, permitiu – via BNPG – fazer a indicação do mesmo indivíduo como o responsável pelo estupro e homicídio de outra vítima, no PR, passados 10 anos, sem a existência de nenhum suspeito. Este trabalho demonstra, portanto, como o labor do Perito Criminalístico de Local impacta diretamente na determinação de autoria e materialidade de um crime, devendo estes sempre se esmerarem para atingir seus objetivos.

O consumo de drogas é um dos principais problemas de saúde pública. Os dados de apreensões de drogas ilícitas feitas pelas Polícias Federal, Estadual e Municipal fornecem dados indiretos do consumo de drogas e permitem traçar o perfil de uso dessas substâncias em uma determinada população. Este estudo teve como objetivo descrever o perfil de apreensão de drogas ilícitas na região Centro-Oeste de Minas Gerais, comparando as informações disponíveis na mídia com os dados reais fornecidos pela Perícia Criminal da Polícia Civil de Divinópolis-MG. É um estudo observacional descritivo realizado por meio da busca de reportagens que abordassem apreensões de drogas em cidades pertencentes à região Centro-Oeste de Minas Gerais e de dados secundários fornecidos pela Perícia Criminal acerca de Registros de Eventos da Defesa Social envolvendo drogas entre o período de 2017 e 2018. Dos 208 detidos identificados nas reportagens, 73,1% são do sexo masculino e 10,6% sexo feminino, com idade média de 21 anos. Dentre as drogas reportadas, a maconha foi a droga mais apreendida seguida pela cocaína e seus derivados. Apesar das maiores apreensões de drogas serem atribuídas pelas reportagens às regionais de Formiga e Bom Despacho, conforme as informações reais da Perícia Criminal, as regionais de Nova Serrana e Pará de Minas foram as com maiores apreensões. O perfil de apreensão de drogas torna-se um referencial importante para subsidiar o planejamento de políticas públicas conforme a real demanda, visando à prevenção do comércio e ao combate ao uso dessas substâncias.
Desenvolvimento de metodologia de baixo custo para geração de amostras de resíduos de incêndio em solo usando etanol
Authors: Da Silva Enzo Matheus Carmo , Rota Alexandre , Neiva Rodrigo , Costa Nelice , Souza Bernardo , Sousa Daniel
Published: July 2020

Situações nas quais verifica-se a ocorrência de incêndios, infelizmente, estão presentes no cotidiano da sociedade moderna. Desse modo, surge, então, a necessidade de elucidar suas causas. Em incêndios dolosos, foco deste estudo, é comum o uso de acelerantes para facilitar a iniciação e propagação do fogo, sendo tais substâncias, geralmente, líquidos inflamáveis. A identificação do líquido inflamável usado como acelerante é uma etapa muito importante da perquirição de um incêndio; no entanto existem várias condições que podem dificultar a detecção de líquidos inflamáveis em locais de incêndios, sendo o tempo máximo para coleta, após a extinção do incêndio, uma das mais desafiadoras. Assim, buscou-se uma metodologia que possibilitasse a geração de amostras de padrões de incêndios. O presente trabalho tem como objetivo examinar os parâmetros que influenciam a detecção de etanol em solo, especialmente o intervalo de tempo máximo que permita a detecção do acelerante fazendo-se o uso de uma metodologia condizente com a realidade do país. Utilizou-se o Latossolo Vermelho como substrato, sendo possível detectar etanol até 72 horas em incêndios simulados, em todas as condições estudadas; fato que sugere que tal metodologia é promissora.
Suicídios por artefatos explosivos – estudo de casos
Authors: Ventura Claiton Pires , Machado Michelle Moreira , Vasconcellos Flávia Armani de
Published: July 2020

A maioria das mortes provocadas por artefatos explosivos são de etiologia acidental, principalmente quando se trata de acidente de trabalho, porém podem ocorrer de modo intencional, como nos casos de homicídios em atentados terroristas e guerras, e também, em casos mais raros, nas tentativas de suicídio ou mesmo suicídio consumado. Os métodos de suicídio mais comuns são enforcamento, armas de fogo ou armas brancas, e envenenamento. O objetivo desse trabalho é relatar três casos de suicídios em que foram utilizados artefatos explosivos do tipo fogos de artifício. Nos três casos analisados houve predileção pelo posicionamento do instrumento na cabeça, havendo grande destruição da região. Além disso, os vestígios eram semelhantes no que tange às projeções sanguíneas, aos fragmentos de tecidos espalhados nos ambientes, tornando claro o resultado do efeito de explosão. Visto que são escassos na literatura os relatos de casos de suicídio em que foram utilizados os fogos de artifício como instrumento para provocar a morte, o presente artigo presta-se ao auxílio de estudos e atuação dos profissionais forenses.

Це дало змогу з’ясувати рівень «існування» одного мистецького твору в іншому мистецькому оприявленні. Результати. У статті в межах компаративних студій здійснений аналіз інтермедіальних відношень між трагедією В. Шекспіра «Ромео і Джульєтта» та настільною грою М. Ескью «Інтриги Верони». З’ясовано, що відношення між цим бінарним об’єктом є вкрай тісними, а саме: сюжетні елементи трагедії, а також герої твору повністю перенесені в площину настільної гри. Звернено увагу на необхідності проведення подальших досліджень у даній сфері (як теоретичних, так і практичних). Наукова новизна. Попри достатню вивченість питання інтермедіальності як мистецького явища та методу аналізу, недослідженими є інтермедіальні відношення між літературними творами та іншими видами мистецтва, зокрема настільними іграми. Практичне значення. Дана стаття може бути використана для подальшого провадження інтермедіальних досліджень у співвідношенні настільна гра-художній твір. Наукові результати дослідження можуть лягти в основу при написанні курсових, дипломних і інших наукових робіт.
IMAGO URBIS: ПАРИЖ У ПОЕЗІЯХ У ПРОЗІ ПОЛЯ ВЕРЛЕНА
Authors: Бігун Ольга
Published: July 2020

Мета. У статті досліджено «паризький текст» Поля Верлена як ментально-географічний простір через опцію концепту «genius loci», важливого з огляду на культурну парадигму міста, його метагеог­рафію. Дослідницька методологія. Методологія дослідження ґрунтується на комплексному використанні системного, філософсько-естетичного, семіотичного підходів; культурно-історичного, контекстуального, міфологічного, біографічного методів. Результати. З’ясовано, що у прозі Поля Верлена «паризький текст» поєднує у собі як літературну топографію, за якою вгадуються ті чи інші ландшафтні «знаки» міста, так і почуття ліричного героя – стомленість, страх, примарні відчуття щастя на фоні міста. Дихо­томія образу загострює опозицію матеріального та духовного вимірів Парижа, оскільки урбаністичні пейзажі з численними прикметами міського життя тісно переплетені зі своєрідним «пейзажем душі», у якому важливі емоції ліричного героя, його враження від навколишньої дійсності. Наукова новизна. Стаття розкриває дискурсивну практику міського простору, що реалізується як протиріччя між закріпленими за знаками сенсами та реальністю, між реальністю як такою і реальністю урбаністичного ландшафту. Практична цінність. Стаття може слугувати основою для подальших досліджень міського простору в літературі.
Low Oxygen Stress During Early Development Influences Regulation of Hypoxia-Response Genes in Farmed Atlantic Salmon (Salmo salar)

Published: July 2020

Survival and growth of developing salmonids are negatively affected by low oxygen levels within gravel nests in natural streams, and hypoxic stress is often experienced by farmed Atlantic salmon (Salmo salar) within hatcheries. Exposure to hypoxia during early development may have long-lasting effects by altering epigenetic marks and gene expression in oxygen regulatory pathways. Here, we examine the transcriptomic response to low dissolved oxygen (DO) in post-hatch salmon reared continuously in 30%, 60% or 100% DO from fertilization until start of feeding. RNA sequencing revealed multiple differentially expressed genes, including oxygen transporting hemoglobin embryonic α subunit (hbae) and EGLN3 family hypoxia-inducible factor 3 (egln3) which regulates the stability of hypoxia inducible factor 1α (HIF-1α). Both hbae and egln3 displayed expression levels inversely correlated to oxygen concentration, and DNA methylation patterns within the egln3 promoter were negatively associated with the transcript levels. These results suggest that epigenetic processes are influenced by low oxygen levels during early development in Atlantic salmon to upregulate hypoxia-response genes.
La geopolítica cinematográfica de los zombis: notas para el debate
Authors: Brito Alvarado Xavier , Levoyer Salas Saudia
Published: July 2020

El zombi ha dejado de ser la estrella de películas de bajo presupuesto y se ha convertido en un concepto científico (biológico, social, económico y tecnológico), en una metáfora para la reflexión de las diversas problemáticas sociales, es un ente que ha pasado de humano a lo poshumano, hasta llegar a ser un antisujeto.  El zombi causa temor en dos direcciones: la primera, en ser devorado por este y la segunda, en convertirse en uno. Su posicionamiento ontológico lo ubica entre el sujeto y el objeto, rompiendo los modelos duales, no importa el género, la condición socioeconómica, ni la geografía, por ello es la metáfora ideal para el análisis social contemporáneo, donde las miradas marxistas, poscoloniales, de género, posestructuralistas, posmodernas y las teorías poshumanistas entran en diálogo. Desde un abordaje teórico, proveniente de la antropología, la sociología y el cine, este ensayo reflexiona al zombi por fuera de las clásicas miradas reduccionistas que lo han ubicado como un producto cultural marginal, destinado a satisfacer momentos lúdicos, contrario a esta postura, lo que se intenta, más bien, es dar una visión crítica del zombi y su injerencia social contemporánea.

Published: July 2020

La dinámica migratoria de América Latina se ha caracterizado por ser intrarregional, la cual es producida por crisis económicas, políticas y humanitarias, lo que ha generado un incremento en los flujos migratorios. En Colombia, según cifras oficiales de migración, al mes de septiembre de 2019, se calculaba que viven 1.825.687 venezolanos, de los cuales el 43.8% se encuentran en situación regular migratoria, es decir, portan cédula de extranjería o Permiso Especial de Permanencia. En el caso de Costa Rica, el mayor porcentaje de migrantes proviene de Nicaragua, cuyos flujos han permanecido constantes. El censo del año 2011 arroja que un 75% de los inmigrantes provienen de Nicaragua, y en el año 2018 el ingreso fue de 198.162 personas. Debido a la ausencia de datos suficientes que permitan comprender el comportamiento de este fenómeno, se realizó una exploración de opiniones de los usuarios de Twitter en Colombia y Costa Rica sobre la migración, desde el 1 de enero hasta el 31 de julio de 2019, por medio de un acercamiento desde el análisis de sentimientos. Mediante el estudio se encontró que las principales preocupaciones de los usuarios de ambos países están enfocadas en las subcategorías de derechos humanos, seguridad y desempleo.

La intervención del derecho de patronazgo en las disputas entre jurisdicciones eclesiásticas: la colegiata de Aguilar de Campoo y el arzobispo de Burgos en 1748
Authors: Corada-Alonso Alberto
Published: July 2020

Con este trabajo se pretende poner de relieve una realidad que afectaba a todos los niveles jerárquicos del organigrama de la Iglesia: los conflictos jurisdiccionales. En este caso concreto se presenta uno de los puntos álgidos de la tensión vivida entre la colegiata de Aguilar de Campoo y la mitra burgalesa. Aunque ambas instituciones estuvieron enfrentadas por cuestiones jurisdiccionales durante buena parte de la Edad Moderna, hubo momentos en que los acontecimientos alcanzaron cotas de violencia que hizo necesaria la intervención de diferentes autoridades judiciales y, finalmente, de la figura del patrón laico de la colegial, que fue el único capaz de reconducir la situación.
La recuperación de la tradición en los mosaicos del Centro Aletti: La presencia de los Padres de la Iglesia en las reinterpretaciones de las figuras de Noé y Lázaro
Authors: Ruiz-de-Loizaga-Martín María
Published: July 2020

En los programas musivos del Centro Aletti, los escritos de los Padres de la Iglesia y otros textos de la tradición cristiana oriental y occidental forman una unidad con ciertas investigaciones teológicas realizadas en los siglos XX y XXI. La íntima relación entre la palabra y la imagen es recuperada de otros periodos artísticos, como el paleocristiano. El objetivo de este artículo es profundizar en la presencia de la patrística y de la iconografía paleocristiana en la configuración de los mosaicos del Centro Aletti, especialmente, en su reinterpretación de las figuras de Noé y de Lázaro. Estas representaciones subrayan la historia de la salvación, también reflejada en las obras que Rupnik realiza como director del Centro Aletti.

An approach for dertemining the synergistic activity of cellulosomal catalytic units in culture media is among essential steps in the research of artificial cellulosomes. Endoglucanase A (CelA) and exoglucanase S (CelS) are two abundant cellulosomal cellulases secreted by anaerobic thermophilic bacterium Clostridium thermocellum and mostly responsible for the cellulolytic activities. They are the well-known candidates of catalytic units for artificial mini-cellulosome. Their synergistic activities play important roles in cellulolytic degradation. CelA cleaves inside the cellulose chains and produces more chain ends for the next step controlling by CelS. While endoglucanase demonstrates distinct activity on carboxymethyl cellulose, it still lacks the specific substrate for quantifying exoglucanase activity. In this research, we introduced an approach for measuring the synergistic activity for these endo and exoglucanase. We designed two recombinant proteins CelA and CelS secreted by the host-cell Bacillus subtilis WB800N in order to investigate their synergistic activity in culture media. The secretory expression was confirmed by tandem mass spectrometry. A modified dinitrosalicylic acid assay was performed on 96 well-plate for quantifying cellulolytic activities of the secreted cellulases in culture media. When adding CelA into CelS, CMCase activities were enhanced and higher than the total of their individual CMCase activities at some cases. When mixing 3 of CelA with 5 of CelS, the CMCase activity was enhanced about 35.5% of the total activities from individual ones. This indicated the synergistic activity of the endo and exoglucanase could degrade cellulose more efficiently than their individual activities. The research also provides the essential materials and methods for further research on designing mini-cellulosome secreted by B. subtilis.

Bagrid catfish (Hemibagrus guttatus Lacepede, 1803) is a wild species of high economic value in Northern Vietnam. Artificial reproduction of bagrid catfish requires sources of quality fingerlings in terms of genetics. In fact, bagrid catfish is endangered due to overhunting. Until now, studying on bagrid catfish was mainly focused on biology characterictics and artificial breeding. In this study, three microsatellite markers were used to assess the genetic characteristics of four bagrid catfish populations (three wild populations collected in Tuyên Quang, Phu Tho, Ha Giang and a cultured population in Hai Duong). These markers were registed Genbwith the code of KJ873116, KJ873117 and NC 023976 for HM7, HM8 and SS1, respectively. All of the loci showed high level of polymorphism with 16 alleles in total which were 5 at locus HM7, 5 at locus HM8, and 6 at locus SS1. Total allele number in population collected in Ha Giang was higher than that of Tuyen Quang, Phu Tho and Hai Duong populations. The mean of number of observed alleles (Na = 3,83 ± 0,24) was higher than the mean number of effective alleles (Ne = 2,14 ± 0,13) and low frequency alleles (< 0,1) were observed in all loci. The value of the expected heterozygosity (He = 0,38- 0,63) was lower than that of the observed heterozygosity (Ho = 0,51-0,71). FIS value was low and the genetic differences between four populations was insignificant as FST < 0,05. The results provide useful information for breeding program and conservation of the bagrid catfish in the future.

Y-chromosome microsatellites or short tandem repeats (STRs) have been proved to be ideal markers to delineate the differences between individuals in human population. Nowadays, Y-STR testing using the PowerPlex® Y23 amplification kit is considered as an extremely sensitive analysis method and has the potential to be used to perform forensic caseworks, and to explore the complexity in population substructures. However, little is known about the forensic Y-chromosome databases in the Vietnam population. In this study, 23 Y-STR loci (DYS576, DYS389I, DYS389 II, DYS448, DYS19, DYS391, DYS481, DYS549, DYS533, DYS438, DYS437, DYS570, DYS635, DYS390, DYS439, DYS392, DYS393, DYS458 DYS456, DYS643, YGATAH4, and DYS385a/b) were investigated in 120 non-related males of the Kinh population in Northern Vietnam using PowerPlex® Y23 system kit (Promega). Our results showed that allele frequencies of 23 loci in the sample population, with the calculated average gene diversity (GD) for each locus, ranged from 0.24 (DYS438) to 0.92 (DYS385a/b). In addition, a total of 120 different haplotypes were found, all of them were unique. Therefore, we found that the haplotype diversity was 1 with a discrimination capacity of 100%, which serves as an essential prerequisite for using Y-chromosomal STR with PowerPlex® Y23 System kit in forensic application in Vietnam. We also compared genetic distances between Kinh population and 10 other neighboring populations from Y-chromosome haplotype reference database (YHRD). The Kinh population is significantly different from other populations. In conclusion, it was indicated that the 23 Y-STR loci were highly genetically polymorphic in the Kinh population in Vietnam and might be of great value in forensic application.

The two hypervariable regions HV-I and HV-II in the D-loop region are the most diverse region in the mitochondrial human genome. These DNA regions have an important role in population genetics and human evolution research. In this study, we identified single nucleotide polymorphisms (SNPs) in the D-loop region of the human mitochondrial DNA genomes of individuals in two Vietnamese ethnic groups: Kinh and Mang. 81 blood samples from 50 Kinh and 31 Mang unrelated individuals were collected for genomic DNA extraction. Using PCR and specific primers, we successfully amplified the two HV-I and HV-II regions with respective sizes of 693 bp and 689 bp. The PCR products then were purified and sequenced. After alignment to the reference mitochondrial genome rCRS (NC_012920.1), 96 SNPs were detected in the Kinh ethnic group, of which many polymorphisms were firstly found in this ethnic and 36 SNPs in the Mang ethnic group. Of the identified 132 SNPs, 16 SNPs were significantly different between the two ethnic groups (p < 0.05). Eight out of the 16 SNPs (T146C, T199C, A16182C, T16217C, T16297C, T16140C, A16183C, T16189C) were frequently found in the Kinh ethnic group but not or only rarely in the Mang ethnic group. On the other hand, 4 SNPs (C151T, A16162G, A16269G, T16271C) were commonly found in the Mang population but rarely in the Kinh population. These findings suggest that although Kinh and Mang belong to one language family (Austro-Asiatic), there is a noticeable diversity in the mitochondrial genomes between these two Vietnamese ethnic groups.
MORPHOLOGICAL AND HISTOLOGICAL CHANGES DURING SOMATIC EMBRYOGENESIS VIA CALLUS OF PANAX STIPULEANATUS H.T.TSAI ET K.M.FENG

Published: July 2020

Recently, saponins in the rhizomes of Panax stipuleanatus H.T.Tsai et K.M.Feng were studied for their effects as an anti-stress, enhancer of blood circulation and vitality, especially against human cancer cell lines. However, the number of individuals of Panax stipuleanatus H.T.Tsai et K.M.Feng in nature is threatened by the indiscriminate exploitation. High-value medicinal plants (belonging to the genus Panax) were propagated by somatic embryogenesis from the stems, leaves and petioles because of easy response to somatic embryogenesis. No report on indirect somatic embryogenesis via callus derived from the rhizomes of Panax stipuleanatus H.T.Tsai et K.M.Feng has been previously published. In this study, the callus was induced from rhizome explants on MS medium ½ macro supplemented in 2 stages with 2,4-D at high concentrations (2 mg/l in 8 weeks and then 1 mg/l in 16 weeks). The callus containing clusters of isolated and isodiametric cells were sub-cultured to a medium containing 0.5 mg /l NAA to obtain embryogenic callus. The callus growing on this medium became looser with clusters of embryonic stem cell: small size, isodiametric cell, large nucleus, clear nucleus and dense cytoplasm. The formation of clusters with homogeneous globular structures occurred at 28 weeks on medium supplemented with NAA. These embryo-like structures pass through developmental stages: late globular-shape, heart-shape, and cotyledon on medium MS medium ½ macro supplemented with 0,5 mg/l BA, 1 mg/l GA3. Besides, there were some abnormal embryos which only develop roots, shoots or just leaves.

Reproductive disorders and respiratory swine (Porcine Reproductive and Respiratory Syndrome - PRRS) is an infectious disease caused by the PRRS virus (PRRSV), spread fast speeds, causing mass death when infected pigs. M protein is one of the major structural protein of the PRRSV, has a molecular weight of about 19 kDa, encoded by the open reading frame 6 (ORF6), which is used to design a subunit vaccine against back PRRSV. In this study, conditions for transient expression of the gene encoded the M protein of PRRSV in leaves of the Nicotiana benthamiana by agroinfiltration method were determined. The results show that optimal conditions for transient expression of protein M in the leaf are used the simultaneous of the A. tumefaciens strain containing vector carrying the gene encoding the protein M and A. tumefaciens containing vector carrying gene encoding supported protein HC-Pro PVY, concentration of acetosyringone with 450 µM, the bacterial cell density used to infect into leaf with OD600 is 0.5, The physiological age of the leaf suitable for infecting bacteria was young leaf and mature leaf of tobacco plants 4 to 6 weeks of age, and the transient expression time of gene encoding protein M of PRRSV in tobacco leaves is most effective 6 days after infecting. This agroinfiltration method can be used to express large amounts of protein - antigen M of PRRSV in tobacco plants to produce vaccines against this virus.
