Azevedo, Rita Ramos. "Critical analysis: portuguese 9th grade exam results and socioeconomic factors." Master's thesis, NSBE - UNL, 2011. http://hdl.handle.net/10362/10051.
Full textThe typical indicator used to assess school performance is average test score results. Literature has pointed out serious weaknesses of this measure as a school performance indicator. The strongest criticism resides in the bias that may exist in socially disadvantaged schools. In fact, this measure does not take into account socioeconomic and other variables which are relevant in determining student‟s school performance and out of the scope of school control. Using school level cross-section data from Portugal for 9th grade exams between 2005 and 2010, I have explicitly calculated the impact of these variables on school achievement as regards exams. I found an important causal effect between socioeconomic variables and school achievement. This implies that average test scores are an intrinsically flawed instrument. For this reason, this study proposes an adjusted measure of school performance. This measure consists of a ratio between current average school scores and expected average school scores, taking into account the reference variables by municipality.

In this work we prove some results of existence and multiplicity of solutions for equations of the type ( ) u + V (x)u = f(x; u) in RN; where 0 < < 1, N 2 , ( ) denotes the fractional Laplacian, V : RN ! R is a continuous function that satisfy suitable conditions and f : RN R ! R is a continuous function that may have critical growth in the sense of the Trudinger-Moser inequality or in the sense of the critical Sobolev exponent. In order to obtain our results we use variational methods combined with a version of the Concentration-Compactness Principle due to Lions.

Full textWhy do African learners continue to be underrepresented in the top 20 positions of the Grade 12 examination results, and what can be done to remedy the situation? Yosso's notion of community cultural wealth shows that it is because our education continues to exclude the African learners' ways of knowing and being that the situation remains as it is. Analysing discourses of top performing white former Grade 12 learners, their teachers, their parents and their former African classmates, indicate that including modes of knowing of all learners in the curriculum irrespective of their race, class, disability or gender may help to create more socially just schooling, which is reflective of sustainable learning environments.

Os elementos de combustível de um reator nuclear de pesquisa tipo MTR (\"Material Testing Reactor\") são, em sua grande maioria, formados por placas de combustível revestidas com alumínio contendo no cerne silicileto de urânio (U3Si2) disperso em matriz de alumínio. Essas placas possuem espessura da ordem de milímetros e comprimentos muito maiores em relação à sua espessura. Elas são dispostas paralelamente no conjunto que forma o elemento combustível, de maneira a formar canais entre elas com poucos milímetros de espessura, por onde escoa o fluido de refrigeração (água leve ou água pesada). Essa configuração, associada à necessidade de um escoamento com altas vazões para garantir o resfriamento das placas em operação, pode gerar problemas de falhas mecânicas das placas de combustível devido às vibrações induzidas pelo escoamento nos canais e, consequentemente, acidentes de proporções graves no caso de velocidade crítica que possa gerar o colapso das placas. Embora não haja ruptura das placas de combustível durante o colapso, as deflexões permanentes excessivas das placas podem causar bloqueio do canal de escoamento no núcleo do reator e levar ao superaquecimento nas placas. Para este trabalho, foram desenvolvidas uma bancada experimental com capacidade para altas vazões volumétricas (Q=100 m3/h) e uma seção de testes que simula um elemento combustível do tipo placa com três canais de resfriamento. A seção de testes foi construída com placas de alumínio e acrílico e foi instrumentada com sensores de deformação, sensores de pressão, um acelerômetro e um tubo de pitot. As dimensões da seção de testes foram baseadas nas dimensões do Elemento Combustível do Reator Multipropósito Brasileiro (RMB), cujo projeto está sendo coordenado pela Comissão Nacional de Energia Nuclear - CNEN. Os experimentos realizados alcançaram o objetivo de chegar à condição de velocidade crítica de Miller com o colapso das placas. A velocidade crítica foi atingida com 14,5 m/s levando a consequente deformação plástica das placas que formam o canal do escoamento. O canal central na entrada da seção de testes apresentou uma abertura de 3 mm em seu centro, causando um grande bloqueio do escoamento nos canais laterais. Este comportamento foi v constatado visualmente durante a desmontagem da seção de testes, ilustrado e discutido na análise de resultados apresentado neste trabalho. O bloqueio dos canais também foi observado por meio de gráficos de queda de pressão e por gráficos das deformações da entrada, centro e saída das placas contra a velocidade média da seção de testes. Observou-se uma queda da resistência hidráulica da seção de testes devido ao aumento da seção transversal de escoamento no canal central e um aumento exponencial das deformações quando da ocorrência da velocidade crítica. Comparativamente, o valor experimental obtido para velocidade crítica na seção de testes foi da ordem de 85% do valor obtido por cálculo com a expressão teórica de Miller. Os experimentos realizados permitiram um melhor entendimento da interação fluido estrutura em elementos de combustível tipo placa como: valores de frequências de vibrações naturais, instabilidade fluido elástica e desenvolvimento de técnicas para a detecção de valores de velocidade crítica.

Full textThis study examined interpersonal relationships among youth from different ethnic communities. The purpose of this study was to examine interpersonal relationships among youth from different ethnic communities in Kenya, especially the vulnerable population of individuals with disabilities, and the ways interpersonal relationships between youth from different ethnic communities change as a result of ethnic conflict. This study utilized survey methodology to gain a better understanding of interpersonal relationships between youth from different ethnic communities and individuals with disabilities. The sample of the survey comprised 42 participants between the ages of 18 and 35 who were in Kenya during the postelection conflict of 2007 and 2008. This study found that some participants experienced strain in their friendships with individuals from different ethnic communities, particularly those that were fighting against one another. Both participation in and harmful action against individuals with disabilities were also reported. However, the experience of youth with disabilities was not dissimilar to that of their nondisabled peers. This study has the capacity to lead to additional studies with a larger sample size within and outside of Kenya, and to break apart key findings into individual studies.

Full textThis research is linked to the project Critical Genre Analysis and implications for multiliteracies (HENDGES, 2012b). Our investigation concern the graphical academic abstract (GAA), a not regular discursive practice at the academic context, which coexists with the academic abstract (AA) in Tables of Contents of scientific journals and at the HTML version of the academic article, combining verbal and visual semiotic modes. Methodologically, we investigated the GAA from the perspective of Critical Genre Analysis (MEURER, 2002; BHATIA, 2004; MOTTA-ROTH, 2006, 2008). This theoretical and methodological approach enables investigate, textually and contextually, the rhetorical organization of the RAG, through the analysis of the different semiotic modes that constitute it, in order to verify standards for defining the RAG as (a new) genre. Forty GAAs from four scientific journals in Biodiversity and Chemistry (CAPES, 2014) were selected. For the contextual analysis we carried out: i) interviews with researchers of the investigated areas; and ii) documental analysis. For textual analysis, we carried out: i) identification, description and categorization of the meanings of semiotic modes that constitute the GAA, based on Systemic Functional Grammar (HALLIDAY; MATTHIESSEN, 2004), on the Grammar of Visual Design (KRESS; VAN LEEUWEN, 2006) and on metadiscourse markers (MORAES, 2005 conf. VANDE KOPPLE, 1985; CRISMORE; FRANSWORT, 1989; BAKHTIN, 1988; 2011, e.g.); and ii) identification of recurrent rhetorical patterns in GAAs (SWALES, 1990). This analysis showed that, although the GAA presents typical rhetorical movements of other academic genres, it is a new genre because the realization of these rhetorical moves is necessarily multimodal, especially realized by the visual semiotic mode. This characteristic differentiates the GAA of the AA because it enhances the communicative multi-purpose to attract the reader and summarize the research reported in an article. The critical study of GAAs allows to interpret new discourses available in the academic context, considering the multiplicity cultural and materialization of meanings. That study can also assist to propose teaching methodologies to promote multiliteracies.
Esta pesquisa está vinculada ao projeto guarda-chuva Análise crítica de gêneros e implicações para os multiletramentos (HENDGES, 2012a). Nossa investigação recai sobre o resumo acadêmico gráfico (RAG), prática discursiva não regular do contexto acadêmico, que, quando ocorre, coexiste com o resumo acadêmico (RA) nos Sumários de periódicos científicos e na versão HTML do artigo acadêmico. O RAG se materializa pela combinação dos modos semióticos verbal e visual. Metodologicamente, propomos investigar o RAG sob a perspectiva da Análise Crítica de Gêneros (MEURER, 2002; BHATIA, 2004; MOTTA-ROTH, 2006, 2008), abordagem teórico-metodológica que possibilita realizar o objetivo de investigar, textualmente e contextualmente, a organização retórica do RAG, por meio da análise dos diferentes modos semióticos que o constituem, a fim de verificar padrões que permitam definir o RAG como (um novo) gênero. Quarenta RAGs de quatro periódicos científicos das áreas de Biodiversidade e de Química (CAPES, 2014) foram selecionados. Para a análise contextual realizamos: i) entrevistas com pesquisadores das áreas investigadas; e ii) análise documental. Para a análise textual, realizamos: i) identificação, descrição e categorização dos significados dos modos semióticos que compõem o RAG, com base na Gramática Sistêmico-Funcional (HALLIDAY; MATTHIESSEN, 2004), na Gramática do Design Visual (KRESS; VAN LEEUWEN, 2006) e nos marcadores metadiscursivos (MORAES, 2005, conf. VANDE KOPPLE, 1985; CRISMORE; FRANSWORT, 1989; BAKHTIN, 1988; 2011, p. ex.); e ii) identificação de padrões retóricos recorrentes em RAGs (SWALES, 1990). Essa análise evidenciou que, embora o RAG apresente movimentos retóricos típicos de outros gêneros acadêmicos, é um novo gênero porque a realização desses movimentos retóricos é necessariamente multimodal, com destaque para o modo semiótico visual. Essa característica o diferencia do RA, pois potencializa o multi-propósito comunicativo de atrair o leitor e sintetizar a pesquisa reportada em um artigo. Esses propósitos dão conta da recorrente necessidade da comunidade científica de otimizar o tempo de busca e seleção de artigos acadêmicos para leitura e de otimizar a divulgação dos resultados da pesquisa científica. O estudo crítico de RAGs possibilita interpretar os novos discursos disponíveis no contexto acadêmico, considerando a multiplicidade cultural e de materialização dos significados, podendo auxiliar na proposição de meios pedagógicos capazes de promover os multiletramentos.

This dissertation aims to develop a collaborative-critical work with a teacher of Science in order to understand and to transform the work with production of written summaries of expository texts which were read by the students. Specifically, this research aims to understand critically the meanings brought by the participants and how they share new meanings on the summary of expository texts as a tool for teaching-learning in Science classes. The research is organized through two socialhistorical activities (Reflexive Session and Class) that are related, in part, by the object summary production and the participants researcher and teacher , that enable the learning concepts to be understood, questioned and shared, like a creative chain (Liberali, 2011) and that contextualize the critical formation for the research participants. It is supported by Social-Historical-Cultural Activity Theory (TASHC), which conceives the man's work activity as a way for transforming society and the man himself. It s also supported by Bakhtin/Volochinov s discussions about the ways the subject is constituted as a social being, inserted in a particular context of communication and implicated in oral and written productions, in these specific situations. The discussions through TASCH provide an understanding of contexts of teacher formation in which the language enables the construction of ZPDs (Zones of Proximal Development) for the participants understanding and sharing of meanings. The contributions given by Dolz & Schneuwly (2004) will assist in understanding language organization in social practices with the genre summary , as a tool of teaching-learning in reading and writing texts. The Collaborative Critical Research, as discussed by Magalhães (2007; 2009; 2010) e Magalhães & Oliveira (2011) supports the methodological choices in close relationship within the theoretical base and the research contents. The analyzed data were produced during Reflexive Sessions with a teacher of Natural Science and through observing some of her classes. The results show the complexity of the collaborative-critical work and the transformation in some concepts on written production of summaries as an instrument of teaching-learning Science
Esta dissertação tem como objetivo geral desenvolver um trabalho colaborativo-crítico com uma professora de Ciências para compreensão e transformação do trabalho com produção de resumos de textos expositivos lidos pelos alunos. Mais especificamente, é objetivo desta pesquisa compreender criticamente os sentidos das participantes e o compartilhamento de significados sobre resumo de textos expositivos como instrumento de ensino-aprendizagem em aulas de Ciências. A pesquisa está organizada por meio de duas Atividades sócio-histórico-culturais (Sessão Reflexiva e Aula) relacionadas, parcialmente, pelo objeto produção de resumo , e pelos participantes pesquisadora e professora , o que possibilita que os conceitos trabalhados sejam compreendidos, questionados e compartilhados, como uma cadeia criativa (Liberali, 2011) e contextualizem a formação crítica das participantes da pesquisa. Está apoiada na Teoria da Atividade Sócio-Histórico-Cultural, que concebe a atividade de trabalho do homem como transformadora da sociedade e do próprio homem. E ainda, nas discussões de Bakhtin/Volochinov (1929) sobre os modos como o sujeito se constitui como um ser social, inserido em um contexto particular de comunicação e implicado em produções orais e escritas, nessas situações específicas. As discussões da TASCH proporcionam a compreensão de contextos de formação em que a linguagem possibilita a construção de ZDPs para a compreensão dos sentidos das participantes e do compartilhamento de significados. As contribuições de Schneuwly & Dolz (2004) auxiliarão na compreensão das organizações da linguagem nas práticas sociais com o gênero resumo, como instrumento de ensino-aprendizagem na leitura e escrita de textos. A Pesquisa Crítica de Colaboração, como discutida por Magalhães (2007; 2009; 2010) e Magalhães & Oliveira (2011) embasa as escolhas metodológicas em estreita relação com a teoria de base e o conteúdo da pesquisa. Os dados analisados foram produzidos em Sessões Reflexivas com a professora de Ciências Naturais e em observações da sala de aula. Os resultados apontam para a complexidade do trabalho colaborativo-crítico e para a transformação de alguns conceitos sobre a produção escrita de resumos como instrumento de ensino-aprendizagem em Ciências

Full textThe Swedish Armed Forces is, since approximately ten years back, experiencing a transformation towards an improved defence capability. The importance of tactical air transport has within this transformation become of greater importance, especially concerning international operations. The author is, however, curios about how tactical air transport is to be implemented within domestic operations. Hence the purpose of the essay is to analyze, with the help of the two doctrines: Militärstrategisk doktrin and Doktrin för luftoperationer, if the resource that the tactical air transport constitutes to the new Swedish Armed Forces is to be seen as a crucial one within domestic operations? To answer the purpose the author analyzes how the new Swedish Armed Forces is intended to operate when it comes to domestic operations, what goals are set up for the tactical air transport and what the situation is like at the moment. The author then uses the theories described in the military doctrines to analyze how tactical air transport can be linked to the new Swedish Armed Forces .There is also a comparison made between the current state of the tactical air transport and the goals set up within the new organisation with the purpose of analyzing what the future might look like. The conclusion is reached that tactical air transport is of great importance to the new Swedish Armed Forces but that it is not to be seen as a crucial resource. The author also predicts that the availability of the aircraft fleet used for tactical air transport will be lower then planned.

Full textThe definition of sexual harassment is phenomena, comments or approaches that are of a sexual nature and from the victim are perceived to be undesirable. Employers have statutory obligations under the Discrimination Act to work on preventive sexual harassment within their own organization. However, #metoo shows in the fall of 2017 that sexual harassment is more prevalent than the public previously believed and thus has increased the critical awareness that employers may have shortcomings in their preventive work on sexual harassment within their own business. The purpose of this study will be to investigate whether employers in the restaurant industry have changed their prevention work on sexual harassment as a result of #metoo and, if so, how this change work is concrete. In order to answer the purpose of the study and problem identification, a method combination consisting of a web survey and further interviews was conducted. The survey was sent by mail as distribution to 265 restaurants, in six pre-selected cities and brought a response rate of 29 %. Based on the survey, the selection was conducted for further interviews, where the requirement was that the restaurant has been noted the hashtag, implemented or planned changes as a result of #metoo, and that the respondent had an interest in participating in a deeper interview. Nine interviews were conducted to highlight how the change work has been implemented. The final result of the study is that 93,5 % were noticed or partially noticed #metoo and its significance, 45,5 % have made changes as a result of #metoo and 54,5 % rejected change. It is clear that it is the more employer who have noticed the hashtag than then chose to make changes. Those who, on the other hand, chose to initiate or plan to initiate a change implemented this in different ways, to different degrees, ambition levels and time perspectives.

Métodos: Estudio de una cohorte prospectiva en que se incluyeron durante 14 meses consecutivos los pacientes ingresados en la UCI del Hospital Universitario Vall d'Hebron sometidos a ventilación mecánica durante más de 48 horas. Se valoró la calidad de vida relacionada con la salud en el ingreso mediante los cuestionarios SF-36 y Cuestionario Respiratorio de Saint Georges (QRSG) y al alta de la UCI. Los mismos cuestionarios se repitieron al año del alta. Los Resultados Sensibles a Intervención de Enfermería (RSIE) y las variables clínicas relacionadas con la patología y la evolución se recogieron de la documentación clínica diariamente. Se realizó un análisis descriptivo y analítico de la relación entre las variables principales. Resultados: La cohorte inicial estuvo formada por 184 pacientes, al año se pudieron estudiar 151. En los componentes resumen (físico y mental) de l’SF-36 y la puntuación total del QRSG existían diferencias estadísticamente significativas entre la valoración al ingreso y al año (p = 0,001; p = 0,001 y p <0,001 respectivamente). Los componentes resumen de l’SF-36 (Físico = 46, Mental = 47) y la puntuación total del QRSG (12 vs 8) tuvieron peores resultados al año que la población de referencia. Ninguno de los RSIE presentaron asociación estadísticamente significativa con los componentes resumen del SF-36 ni con el QRSG. Conclusiones: Los pacientes que requirieron ventilación mecánica durante su ingreso en la UCI presentaron mejor calidad de vida al año del alta que la que presentaban al ingreso, aunque continuó siendo peor que la de la población de referencia. No se pudo determinar relación entre los resultados sensibles a intervenciones enfermeras y la calidad de vida al año de los pacientes.
Objective: To assess the HRQL of mechanically ventilated patients admitted to ICU and its relation to nurse-sensitive outcomes (NSO). Methods: A prospective cohort of admitted to d'Hebron University Hospital ICU who underwent mechanical ventilation for more than 48 hours were included for 14 consecutive months. Health-related quality of life at admission and discharge from ICU was assessed using the SF-36 and Saint Georges Respiratory (QRSG) questionnaires. The same questionnaires were also utilised 1 year after ICU discharge. Nursing Sensitive Outcomes (NSO) and clinical variables related to patient’s diagnosis and clinical course were collected from patient records on a daily basis. A descriptive and analytical analysis of variables’ relationship performed. Results: The initial cohort consisted of 184 patients. Follow-up a year after discharge was done on 151 patients. In the summary components (physical and mental) of the SF-36 as well as the total score of the QRSG there were statistically significant differences between the assessment performed at ICU admission and the one performed a year after ICU discharge (p = 0.001, p = 0.001 and p <0.001, respectively). The summary components of the SF-36 (Physical = 46, Mental = 47) and the total QRSG score (12 vs 8) results obtained a1 year after ICU discharge were worse if compared with the ones obtained from the reference population. None of the NSO had a statistically significant association with the SF-36 summary components or any dimension of the QRSG. Conclusions: Patients who required mechanical ventilation during ICU admission had better quality of life 1 year after ICU discharge when compared with ICU admission, but was worse when compared with the reference population. It was not possible to determine if there is a relationship between NSO and quality of life a year after ICU discharge.

Full textIntroduction: In 70% of cases, the general practitioner ends up in a situation of diagnostic uncertainty at the end of a consultation. He must remain vigilant concerning two dangers: in one hand, making a mistake in the diagnosis, and on the other, failing to detect a serious disease. The “résultat de consultation” (RC) concept helpsdefine the most frequent clinical situations, to designate them precisely and thus control the first danger. We focused our work on managing the second danger; that is to say, failing to detect a serious disease. By creating a risk management method called “démarches cindyniques“, we tried to answer the following question: Is it possible to draft approaches to risk analysis that are adapted to the most frequent clinical situations in general medicine? Materials and methods : The work has been carried out by a group of eight general practitioners, and has been divided into four steps: a thorough review of articles, the development of a method to create approaches to risk analysis, their application to 20 CRs, and lastly, its evaluation done by 785 general practitioners using the Likert scale. Results: Through this work, we developed theapproaches of risk analysis of 5 out of the 20 RC: "arthopathie-périarthropathie", "dépression", "réaction à situation éprouvante", "rhinite" and "toux". The analysis of the approaches' evaluations shows an extensive support from the general practitioners. Three-quarters of them evaluate the interest of these approaches at 7/9 and 84% find them useful in their daily work, rating their interest over 7/9. General practitioners using the Dictionnaire des Résultats de consultation® (DRC) generally give better evaluations. Conclusion: The creation of these approaches to risk analysis is feasible and is widely welcomed by general practitioners. The next steps will be the generalization of this method for the whole DRC and then forpolypathology which represents the core of our profession

The topic of this thesis is to improve the ionograms scaling results of the critical frequency of F2 layer (foF2). Comparing the foF2 scaling results between the automatic scaling program by using a fuzzy segmentation and a connectedness algorithm and by human eyes, the absolute values of differences between two scaling results less than 1 MHz are less than 60% for the chosen 2304 ionograms. The improved automatic scaling program filters the echo not belonging to the F layer, and then using the F layer echoes to determine the foF2. The absolute values of differences between two scaling results less than 1 MHz are more than 85%, better than the previous program. This thesis also discusses the accuracy of the scaling results. The 2304 ionograms were obtained by the Dynasonde that was established at Dong-Hwa University in Hualien, Taiwan since 2010.

Full textBackground The Biochemistry and Haematology Outcome Model (BHOM) relies on the results from routine index blood tests to predict the patient risk of death. We aimed to externally validate the BHOM model. Method We considered all emergency adult medical patients who were discharged from Northern Lincolnshire and Goole (NLAG) hospital in 2014. We compared patient characteristics between NLAG (the validation sample) and the hospital where BHOM was developed. We evaluated the predictive performance, according to discriminative ability (with a concordance statistic, c), and calibration (agreement between observed and predicted risk). Result There were 29 834 emergency discharges of which 24 696 (83%) had complete data. In comparison with the development sample, the NLAG sample was similar in age, blood test results, but experienced a lower mortality (4.7% vs 8.7%). When applied to NLAG, the BHOM model had good discrimination (c-statistic 0.83 [95% CI 0.823 - 0.842]). Calibration was good overall, although the BHOM model overpredicted for lowest (<5%, observed = 229,predicted =286) and highest (≥50%, observed = 31, predicted = 49) risk groups, even after recalibrating for the differences in baseline risk of death. Conclusion Differences in patient case-mix profile and baseline risk of death need to be considered before the BHOM model can be used in another hospital. After re-calibrating for the baseline difference in risk the BHOM model had good discrimination but less adequate calibration.

Hepatitis B virus (HBV) is the major etiology of chronic hepatitis B (CHB), liver fibrosis, liver cirrhosis and hepatocellular carcinoma (HCC). Although antiviral therapy may suppress HBV replication and hepatic inflammation, there is no effective treatment to cure CHB. Because of high spontaneous error rate of HBV reverse transcriptase which has little proofreading ability, the HBV are prone to mutate during replication. Under the pressure of host`s immune attack, the HBV may escape the host`s immune attack by deletion of hepatitis B surface immune epitope. Although mutations may help HBV escape immune attacks, it also affect the HBV morphology and physiology. It had been reported that mis-folding of HBsAg with deletion segment might result in HBsAg retention in endoplasmic reticulum (ER) and induced oxidative stress, subsequent chromosome instability and activation of hepatocarcinogenesis pathways. It is one of reasons that pre-S deletions of HBV are more frequently found in HCC patients. In our recent study, HBV mutant with pre-S deletion were significantly associated with postoperative HCC recurrence only in the presence of high viral loads and HBsAg levels. Among the 216 HCC patients with complete HBs gene sequencing, 73 had the pre-S deletion HBV mutants, including 15 with the pre-S1 deletion mutant only, 43 with the pre-S2 deletion mutant only, and 15 with both. Of the 58 patients with the pre-S2 deletion mutants HBV, 25 (43.1%) had the deletion that ended at the amino acid 142 of the pre-S region. Proline was the preserved amino acid on this site in all of these mutants. It will be an interesting issue worthy of investigation if Proline at this location plays a key role in HBV assembly and secretion which results in the maintenance of viral quasi-species. In this study, human HCC cell line Huh 7 was transfected in vitro with wild type of HBV plasmid and different pre-S Proline142 mutant plasmids. We compared viral replication, transcription, translation of viral antigens, assembly and secretion between wild type and pre-S deletion by western blot, southern blot and northern blot. Interestingly, a single amino acid deletion or substitution of Proline at the residue 142 of pre-S region resulted in marked reduction of secreted HBsAg in culture medium and high retention of HBsAg than WT group in ER. The immunofluorescence also show that only WT group HBsAg diffused distribution in cell cytoplasm. However, all the MT groups HBsAg showed overlapping with ER at the marginal part of hepatocyte nucleus. This finding is original and supported our previous findings that Proline is critical in viral assembly and secretion. In addition, we also observed our data indicates that the hot-spot short segment deletion in the pre-S region markedly reduces HBV secretion and results in retention of mutated HBsAg in the ER. Furthermore, the P142 of the pre-S region plays a key role in HBV secretion to circulation.
