No. of bitstreams: 1 Marcela Potrich Peluffo.pdf: 226215 bytes, checksum: 738e3b8accac2fd4d75e3a41daded914 (MD5) Previous issue date: 2014-03-27 / The World Health Organization estimated depression as the third cause of disability in the ranking of all diseases, responsible for 4.3% loss of healthy life years (DALY). The depressive disorder impairs the ability to function, leading to deficiency in the production of more than 50% of patients. The treatment may be pharmacotherapy, psychotherapy, and in some cases eletroconvulsive therapy. This study examined the prevalence of the use of antidepression medications in the city of São Paulo, Brazil and is part of a large study Pos traumatic stress disorder on the São Paulo city: prevalence, commordity and associated factors. This is a one phase cross-sectional survey carried out in São Paulo, Brazil. A multistage probability to size sampling scheme was performed in order to select the participants (3000). The measurements included psychiatric diagnoses (CIDI 2.1), and psychoactive medications. The interviews were carried between June/2007 February/2008. The statistical analyses will be weight-adjusted in order to take account of the design effects. The frequency of use of psychoactive medications in individuals with depressive disorder 13%, 12,8% make use of antidepressant medication and 8% benzodiazepines, so with a large number of concurrent use of two medications. Among those who are using antidepressants, 63% use selective serotonin reuptake inhibitors, 34% use a tricyclic antidepressant and the other 3% make use of selective inhibitors of noradrenaline reuptake and various antidepressants. Was associated with the use of antidepressant medications females (2,7; IC 95% 1,5 ¿ 4,9), age over 30 years, being widowed or divorced or separate without living with the partner, with schooling above 13 years. It was concluded that there is a great way to go in our country in relation to mental health policies. Advances such as ensuring access to medicines and qualified professionals have already occurred, but show still insufficient. / A Organização Mundial da Saúde estima a depressão como a terceira causa de incapacidade no ranking de todas as doenças, responsável por 4,3% de perda de anos de vida saudáveis (DALY). O transtorno depressivo prejudica a capacidade laboral de mais de 50% dos pacientes. Os tratamentos podem ser farmacoterapia, psicoterapia e, em alguns casos, o tratamento eletroconvulsivante. O objetivo deste estudo foi avaliar o uso de medicamentos antidepressivos em indivíduos com diagnóstico de transtorno depressivo na população da cidade de São Paulo, Brasil. Um estudo de corte transversal foi realizado com amostra probabilística, em multiestágios, da população da cidade de São Paulo, Brasil. Foram entrevistados 2536 indivíduos. As medidas incluíram diagnósticos psiquiátricos (CIDI 2.1) e o uso de medicamentos psicoativos, incluindo antidepressivos. As entrevistas foram realizadas entre Junho/2007 e Fevereiro/2008. As estimativas foram ajustadas para o efeito do desenho por meio da análise de amostras complexas. A prevalência de uso de medicação psicoativa em indivíduos com transtorno depressivo foi de 13%, 12,8% utilizando de medicação antidepressiva e 8% benzodiazepínicos, portanto com número grande de uso concomitante das duas medicações. Entre aqueles que fazem o uso de antidepressivos, 63% usam inibidores seletivos da recaptação de serotonina, 34% usam antidepressivo tricíclico e os outros 3% fazem o uso de inibidores seletivos da recaptação de noradrenalina e antidepressivos variados. O uso de medicamentos antidepressivos esteve associado ao sexo feminino (2,2; IC 95% 1,0 ¿ 5,0), idade acima de 30 anos (2,7; IC 95% 1,1 ¿ 6,5), ser viúvo ou divorciado ou separado não morando junto com o parceiro (2,0; IC 95% 1,0 ¿ 4,2), com escolaridade acima de 13 anos (3,1; IC 95% 1,2 ¿ 7,9). Foi concluído que há um grande caminho a ser percorrido em nosso país em relação às políticas de saúde mental. Avanços como a garantia de acesso aos medicamentos e profissionais qualificados já ocorreram, mas se mostram ainda insuficientes.

In Chapter I is a general description of novel metal complexes which hydrolytically cleave peptides, proteins, DNA, and other biological molecules. These reagents are becoming the more important as potential therapeutic agents. A panel of ligands was investigated for coordination to ZrIV and other metals in groups 4, 5, and 6 to effect the greatest degree of hydrolysis. Chapter II describes a ZrIV complex which is capable of hydrolyzing a 30 amino acid peptide, insulin chain B, with amino acid specificity. Oxidized insulin chain B peptide was hydrolyzed after only 4 h of treatment at pH 7.0 and 60 °C using ZrCl4 in the presence of 4,13-diaza-18-crown-6. MALDI-TOF and ESI LC-MS mass spectra indicated that insulin chain B was hydrolyzed by ZrIV at the Gly8-Ser9, Ser9-His10, and Gly20-Glu21 amide bonds within the oligopeptide. To our surprise, the cysteine sulfonic acid sequences Cys(SO3H)7-Gly8 and Cys(SO3H)19-Gly20 were also cleaved. To the best of our knowledge, this constitutes the first example of metal-assisted hydrolysis of a Cys(SO3H)-Xaa amide bond. This is significant in light of the fact that cysteine sulfonic acid formation in proteins is triggered by oxidative stress and has been associated with amyloid fibril formation, Parkinson’s disease, and other deleterious, physiological processes. Chapter III describes the metal-assisted hydrolysis of sphingomyelin which is a principle phospholipid component of animal cell membranes. The sphingomyelin assays showed evidence of metal-assisted hydrolysis after 20 h of treatment at lysosomal pH 4.8 and cytosolic pH 7.0 at both physiological temperature 37 °C and 60 °C. The metal ion CeIV was the most reactive, followed by ZrIV, and then HfIV. The goal of this work is to develop metal-based reagents to reverse the lethal build-up of sphingomyelin that occurs in lysosomes of patients suffering from Niemann-Pick disease.

Background: Despite an abundance of questionnaire data, the prevalence of clinically significant and medically unexplained pain syndromes in the general population has rarely been examined with a rigid personal-interview methodology. Objective To examine the prevalence of pain syndromes and DSM-IV pain disorder in the general population and the association with other mental disorders, as well as effects on disability and health-care utilization. Methods: Analyses were based on a community sample of 4.181 participants 18–65 years old; diagnostic variables were assessed with a standardized diagnostic interview (M-CIDI). Results: The 12-month prevalence for DSM-IV pain disorder in the general population was 8.1%; more than 53% showed concurrent anxiety and mood disorders. Subjects with pain disorder revealed significantly poorer quality of life, greater disability, and higher health-care utilization rates compared to cases with pain below the diagnostic threshold. The majority had more than one type of pain, with excessive headache being the most frequent type. Conclusions: Even when stringent diagnostic criteria are used, pain disorder ranks among the most prevalent conditions in the community. The joint effects of high prevalence in all age groups, substantial disability, and increased health services utilization result in a substantial total burden, exceeding that of depression and anxiety.

Studien försöker belysa vilka svårigheter elever som läser det individuella programmet möter och vilka möjligheter de har i deras strävan att gå vidare till ett nationellt program. Studien ger också svar på frågan om IV-elever trivs med att läsa programmet och om de börjar en gymnasieutbildning efter IV. Jag ville också ta reda på om vad elever i grundksolans årskurs nio tyckte om informationen om gymnasieskolan, och om alla fick chansen att prata med en studie- och yrkesvägledare. Studien belyser också frågan om ursprung har en viss betydelse för fortsatta studier på nationella program. / The study tries to illustrate the difficulties students enrolled in the Individual program (IV) meet and the opportunities that will arise if pursuing studies in a National Program. The study also provides answers to the question if IV students find the program rewarding and enjoyable, and to what extent they pursue high school studies after the IV. I also wanted to find out what the students in the ninth grade of compulsory school thought about the information they received regarding the high school education, and if everyone got the chance to talk to a guidance counselor. Furthermore, the study also evaluates whether heritage plays a certain role with regard to further studies on the National Program.

Det är få individer som väljer att inte studera vidare på gymnasiet efter grundskolan. Det `val´ elever har som inte är behöriga men vill gå på ett nationellprogram på gymnasiet är det Individuella programmet (IV). Syftet med denna uppsats är att synliggöra elevers upplevelser av att studera på IV. En kvalitativintervjustudie har använts och resultatet visar att elevers självbild påverkas av att gå på IV. Respondenterna som gick på IV hade ofta en negativ självbild, som påverkats av flera olika faktorer. Under tiden på IV förbättrades deras motivation till studier, vilket märktes bland annat på ökad närvaro jämfört med i grundskolan. Den ökade motivationen berodde på en stärkt tilltro till den egna förmågan. Detta har skett tack vare att respondenterna brutit mönster, haft engagerad personal och att de hade framgång inom områden där de tidigare misslyckats. / Very few students chose to not continue school after 9th grade. The ones that lack grades for upper secondary school, have the option go to an individual program (IV) to get them. The purpose with this thesis is to make students experiences from IV visible. A qualitative interview method has been used. The result shows that the pupils at IV have a low self-image. During the time at IV the respondent’s motivation gets stronger because of enlarged self efficacy. That’s because of engage staff and success in areas that the individual was unsuccessful in earlier.

銅銻硒礦是具有 0.3 eV狹窄能帶間隙的P型半導體，且已被發現是在中溫區下極具潛力的熱電材料。銅銻硒礦的晶體結構具有三維銅硒子框架可提供導電的電洞，而有較高的功率因子900 μW/mK2。銻硒四面體結構可藉由其他元素取代銻的位置，扭曲其鑽石結構以達到提高功率因子以及降低熱傳導的目的。理論預測可藉由 IV 族元素鍺、錫、鉛和過渡金屬鈦等元素取代銻來提供電洞載子。本研究藉由燒結與電漿放電製備樣品，探討鈦、錫、鉛、鍺取代銻的熱電效應。 在上述之元素取代效應後，鈦與鉛並沒有帶來顯卓的熱電效應提升，反之錫與鍺能有效地提升電洞載子濃度，然而與摻錫的研究相似的結果已被其他團隊發表，惟鍺的取代效應則尚未被做完整的探討。2 % 鍺的取代有1200μW/mK2的功率因子，相較於母材(900μW/mK2)有 30 % 的提升，因此我們會對鍺的取代效應做完整一系列的研究。摻雜比例從 1~8 % 的結果裡，發現晶格熱傳導係數隨摻雜比例提升減少的合金效應，然而高於 6 % 的取代造成電導大幅提升，使得熱傳導的載子貢獻高於 50% 並嚴重降低載子移動率，致使功率因子大幅衰減與優質係數降低。 4% 的鍺摻雜在提高功率因子與降低熱傳導係數上皆有顯卓的表現，使得優質係數在溫度650 K達到 0.7 相對於母材 (0.54) 有30 ％的提升。 / Cu3SbSe4 is a p-type semiconductor with a narrow band gap near 0.3 eV, and has been found to be a promising thermoelectric material at medium temperatures. The crystal structure of Cu3SbSe4 consists a three-dimensional [Cu3Se4] framework acting as electron hole conduction pathway which cause high power factor near 900 μW/mK2. The inserting guest atom to the Sb site of tetrahedral [SbSe4] framework cause a more distorted diamond-like structure, thus providing a relatively lower lattice thermal conductivity in relatively large electric conductivity. According to theoretical predication which are based on the defect formation energy and band structure calculations, p-type doping can be achieved by substituting Sb with group IV elements, as Ge, Sn, and Pb, and transition metals as Ti. This study is investigation of the doping effect in Cu3SbSe4 semiconductor which are prepared by melting and spark plasma sintering. Herein, we take a close look at the thermoelectric properties of Cu3SbSe4 which are mentioned in previous paragraph. No significant change in results of Ti and Pb. Carrier concentrations are dramatic increasing in results of Sn and Ge, but the results of Sn substitution were already reported by another group. Power factor of Ge substitution is 1,200μW/mK2 which is 30 % more than raw material. We did more study in germanium doping series because it have high power factor which did not be investigated in Cu3SbSe4. Alloy effects, as description of lattice thermal conductivity reducing with doping fraction increasing, are explored in Ge doping fraction from 1 % to 8 %. Although electric conductivity were largely enhanced, figure of merit were reducing by electric contribution of thermal conductivity were higher than 50 % and carrier mobility were significantly reducing when the doping fraction were higher than 4 %. Doping fraction in 4 % have relatively high power factor and relatively low thermal conductivity. Figure of merit in 4 % doping fraction is 0.7, as 30% more than 0.5 of raw material.

In this work we have investigated the catalytic activity of four metal complexes which exhibit Lewis acid character: dibutyltin diacetate, dibutyltin dilaurate, butylstannoic acid and di-n-butyl-oxo-stannane. With the aim to obtain a mixture of fatty acid esters, called biodiesel, these catalysts have been tested in alcoholysis of soybean and castor oils. Transterification experiments of the vegetable oils have been carried out using two types of apparatus. The first was a glass reactor connected to a reflux condenser. The second was a pressurized container (inoxidable steel reactor), containing a manometer and a temperature controller. In all transterification experiments carried out, the use of the steel reactor were more efficient face to the analogous reactions carried out with the glass reactor. The alcoholysis were also carried out in more severe conditions. The reactions were carried out at higher temperatures, from 80 to 150°C. It was observed that the reaction yield increases, increasing the reaction temperature. In a second stage of this work, the transesterification reaction of the soybean oil was carried out employing methylic, ethylic, iso-propylic, n-butylic and iso-butylic alcohols. The effect of the different type of alcohols in the reaction yield were evaluated. It was remarked that higher yields were obtained with long chain alcohols (butanol and isobutanol) which were similar to that observed with conventional ones (methanol and ethanol). Finally, the use of metal complexes of tin(IV) as catalysts for transterification reactions of vegetable oils to obtain biodiesel seems to be very promising. The experimental data, discussions, and conclusions are described on this dissertation. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho investigou-se a atividade catalítica de quatro complexos metálicos exibindo caráter ácido de Lewis: dibutil diacetato de estanho, dibutil dilaurato de estanho, óxido de dibutil estanho e ácido butil estanóico. Estes catalisadores foram testados na alcoólise do óleo de soja e de mamona para a obtenção de uma mistura de ésteres de ácidos graxos, denominada biodiesel. Nos experimentos de transesterificação dos óleos vegetais, as reações foram realizadas em dois tipos de equipamentos. O primeiro equipamento era composto de um reator de vidro acoplado a um condensador de refluxo. O segundo equipamento foi composto de um reator de aço inox, hermeticamente fechado, equipado com um manômetro e um controlador de temperatura. Em todos os experimentos de transesterificação realizados o uso do reator aço inox mostrou-se mais vantajoso frente ao reator de vidro com condensador de refluxo. A alcoólise dos triglicerídeos também foi desenvolvida em condições mais enérgicas de reação. As reações foram realizadas em temperaturas que variaram entre 80 °C e 150 °C. Observou-se que o aumento da temperatura geralmente favorece o aumento no rendimento da reação. Em outra etapa deste trabalho a transesterificação do óleo de soja foi realizada empregando-se os álcoois metílico, etílico, isopropílico, butílico e isobutílico. Os efeitos dos diversos tipos de álcoois no rendimento final da reação foram observados e avaliados. Destacaram-se nesses experimentos os altos rendimentos obtidos com os álcoois de cadeias longas (butanol e isobutanol) quando comparados com os álcoois convencionais (metanol e etanol). Por fim, o uso de complexos metálicos a base de estanho(IV) mostrou-se promissor na reação de transesterificação de óleos vegetais visando a obtenção de biodiesel. Os dados relativos aos experimentos, a discussão dos resultados e as conclusões estão descritas nessa dissertação.

Václav Žůrek Comparison of the Use of Historical Motives in the Monarchical Legitimacy in Kingdoms of France and Bohemia in the Late Middle Ages Abstract Concepts of the past are most important parts in the formation of individual and collective identity. Medieval authors deliberately used the historical narratives as a means of enhancing the cohesion of respective social groups, usually the ruling strata of society. The doctoral thesis focuses on re-interpretations and exploitations of the past in France and Bohemia during the 14th century, on the role of historical narratives in the self-representation of the ruling dynasties Luxembourg and Valois, and on the perception of their own role in the history. Main question of the thesis is the social and literary context of the shaping of an imagination of the past: detailed comparison between the Latin and vernacular historiographical production at the royal courts in France and Bohemia bring also crucial observations as to the ways and means of cultural transfer between the respective centres of power.

Wenceslaus IV. is traditionally considered as a not very capable monarch, in contrast to his successful father, Emperor Charles IV. Not even modern historiography works are without a flattened negative view on this ruler. The aim of this work is to relativize Wenceslaus' alleged ruling inability in an example of his policy in Lands of the Bohemian Crown, namely in Lower Lusatia between years 1364-1419. The issue of the crown countries in this period has been so far in the background of Bohemian researchers' interest. Emphasis is placed on the socio- cultural background of Lusatian Margrave at the end of the 14th century and it is possible to also evaluate the position of Lower Lusatia throughout the whole Bohemian Crown. The focus of the thesis is an analysis of specific Wenceslaus' political steps, mainly based on charters research. The work is also focused on exploring the relationship between the sovereign and the Lower Lusatian nobility, cities and churches. The scope is also devoted to the contribution of John of Gorlitz and Jost of Moravia to the administration of Margrave. By analyzing the above- mentioned aspects, is possible to enrich the view of the government of Wenceslaus IV. and to relativize the traditional narrative of his inability to govern. Finally, it can prove the continuity of...

The type IV secretion system can be classified as a large family of macromolecule transporters divided in three recognized sub-families involved in different bacterial functions. The major sub-family of T4SS is the conjugation system, which allows transfer of genetic material as a nucleoprotein via cell contact among bacteria. Analogously to bacterial conjugation, the T4SS can transfer genetic material from bacteria to eukaryotic cells; such is the case of T-DNA transfer of Agrobacterium tumefaciens to host plant cells. The system of effector proteins transport constitutes the second sub-family, being indispensable for infection processes of several mammalian and plants pathogens. The third sub-family corresponds to the DNA uptake/release system involved in genetic transformation competence, independently of cell contact, as it was described to the systems VirB/D4 from Campylobacter jejuni and ComB form Helicobacter pylori. Several essential features of T4SS are well known, but the knowledge in support of an uncomplicated classification or proper protein annotation of system subunits remains confusing, which in same cases can avoid making inferences about evolution of the system in bacterial species. The purpose of this work was to organize, classify and integrate the knowledge about T4SS through building a database devoted to this bacterial secretion system. The T4SS database was created using the SGBD MySQL and Perl programming language and with a web interface (HTML/CGI) that gives access to the database. Currently, this database hold genomic data from 43 bacteria and 10 plasmids acquired from the GenBank NCBI, these organisms comprise groups from Actionobacteria to Gram-negative Proteobacteria including symbiotic and pathogenic bacteria. By applying Bidirectional Best-Hits method was possible to get a core set of 75 clusters with 974 proteins involved in the T4SS. Also, during this procedure BlastP, Muscle e ClustalW algorithms were applied. The database was manually annotated supported by cross references built-in the T4SS annotation pages, such as the UniProtKB/Swiss-Prot, COG, InterPro and TCDB as well as by the methods for signal peptide and transmembrane regions prediction. All T4SS protein records scattered into 75 ortholog clusters were organized into five different classes of type IV secretion system proteins: (i) Type IVA Mpf/T4CP; (ii) Type IVA Dtr; (iii) F-type plasmid; (iv) IncP-1-type plasmid; (v) Type IVB Icm/Dot. All 974 proteins were annotated into 68 well-known families, which can be involved in conjugation, effector translocator, DNA uptake/release or even can be bifunctional proteins. Also, by using the Maximum Likelihood method were built 70 unrooted phylogenetic trees that represents just 70 clusters instead of 75, this is due to five clusters had only two protein sequences, five unrooted phylogenetic trees were built for each group of first hierarchical classification, one unrooted phylogenetic trees including proteins from archetype systems of all groups, one unrooted phylogenetic trees from 16S sequence of each organism and one rooted tree including a sequence from a Gram-positive bacteria as an external group. The phylogenetic analyses show that some proteins of T4SS are more divergent than others, which indicate that for a particular function few sequence mutations were needed, but other proteins required many sequence mutations to get another functions. Thus, these results proved that proteins belong to the same cluster show different functions: conjugation, DNA uptake/release or effector translocator. Consequently, it was possible verify that similar functions were grouped together within phylogenetic tree, which allowed to annotate a probable function of some uncharacterized proteins, that is possibly due to the sequence similarity may reveal a similar evolution to get the same function. Thus, the phylogenetic trees allowed confirming the protein annotation as well as inferring whether uncharacterized proteins would encompass a known function. The T4SS database will be an open access, given to the users searching and submission sequence tools, which will permit to get insights about classification and phylogeny of T4SS sequence of interest. T4SS Database is accessible at the URL http://www.t4ss.lncc.br. / O T4SS pode ser classificado como uma família de transportadores de macromoléculas envolvidos em diferentes funções bacterianas. A maior subfamília do T4SS é a do sistema de conjugação, o qual permite a transferência de material genético entre bactérias. Analogamente à conjugação, o sistema pode transferir material genético entre bactérias e eucariotos, tal como a transferência de T-DNA de Agrobacterium tumefaciens. O sistema de transporte de proteínas efetoras constitui uma segunda subfamília do T4SS, sendo indispensável nos processos de infecção de vários patógenos de mamíferos e plantas. A última subfamília corresponde ao sistema DNA-uptake/release" que funciona independente de contato com uma célula alvo, representado pelos sistemas VirB/D4 de Campylobacter jejuni e ComB de Helicobacter pylori. Muitas características básicas do T4SS são bem conhecidas, entretanto o conhecimento para a classificação simples e intuitiva ou a anotação apropriada das proteínas ainda não está claro, impedindo em alguns casos estabelecer correlações evolutivas deste sistema em bactérias. O objetivo deste trabalho foi o de organizar, classificar e integrar o conhecimento do T4SS através da construção de um banco de dados especializado para este sistema secretório bacteriano. O banco de dados T4SS foi criado utilizando o SGBD MySQL e a linguagem de programação Perl e com uma interface web (HTML/CGI) que fornece acesso ao banco. Este banco consta atualmente com 43 genomas bacterianos e 10 plasmídeos obtidos do GenBank NCBI, estes organismos vão desde Actinobactérias até Proteobactérias Gram-negativas, incluindo simbiontes e patogênicos. Foi utilizada a metodologia do Bidirectional Best-Hits", com a qual foi possível obter um conjunto mínimo de 75 clusters" com 974 proteínas envolvidas no T4SS. Também, durante este procedimento foram utilizados os algoritmos BlastP, Muscle e ClustalW. O banco foi anotado manualmente utilizando referências cruzadas incluídas nas páginas de anotação do T4SS, tais como UniProtKB/Swiss-Prot, COG, InterPro e TCDB e métodos para predição de regiões de peptídeos sinal e transmembrana. As análises do banco T4SS permitiram criar uma classificação hierárquica e funcional para as proteínas do T4SS, consistindo em cinco grupos: (i) Type IVA Mpf/T4CP; (ii) Type IVA Dtr; (iii) F-type plasmid; (iv) IncP-1-type plasmid; (v) Type IVB Icm/Dot). As 974 proteínas foram anotadas em 68 famílias conhecidas, as quais podem estar envolvidas em conjugação, transferência de T-DNA, transferência de proteínas efetoras, DNA-uptake/release" ou bem serem proteínas bifuncionais. Também, através do método de máxima verossimilhança foram geradas 70 árvores filogenéticas não enraizadas (NR) representando apenas 70 clusters, já que cinco clusters apresentaram apenas duas seqüências de proteínas, cinco árvores filogenéticas NR foram criadas para cada grupo da primeira categoria hierárquica, uma árvore NR com representantes de todos os grupos, uma árvore NR gerada a partir das seqüências 16S de cada organismo e uma árvore de um cluster incluindo uma seqüência de bactéria Gram-positiva como grupo externo. As análises filogenéticas mostram que determinadas proteínas do sistema são mais divergentes que outras, indicando que para uma determinada função poucas mutações de seqüências foram necessárias, já outras proteínas precisaram de maiores mutações para adquirir outras funções. Por isso, verifica-se que proteínas de um mesmo cluster apresentam diferentes funções: conjugação, DNA-uptake/release", traslocadores de proteínas efetoras. Conseqüentemente, foi possível verificar que funções semelhantes se agruparam juntas nas árvores filogenéticas, permitindo anotar uma função provável das proteínas ainda não caracterizadas (unknown"), isto possivelmente devido a que em virtude de sua semelhança de seqüências, possivelmente evoluíram para realizar a mesma função. Assim, as arvores possuíram a finalidade de confirmar a anotação e contribuíram permitindo inferir se os unknown" ou probable" podem ser de uma determinada classificação funcional. O banco T4SS será de uso público, oferecendo ao usuário ferramentas de buscas e submissão de seqüências, as quais permitirão inferir respostas sobre a classificação e filogenia da seqüência T4SS de interesse. O banco de dados T4SS pode ser acessado na URL: http://www.t4ss.lncc.br.
