			<content:encoded><![CDATA[<div><strong>A SIDA matou no ano passado cerca de dois milhões de pessoas em todo o mundo, mas 2010 traz um certo optimismo com a redução de novas infecções, os novos tratamentos contra a doença e os meios adicionais para prevenir a transmissão.</strong></div>
<div><strong><br />
Na véspera do Dia Mundial de Luta contra a SIDA, que será comemorado nesta quarta-feira, os especialistas e as associações recordam que, desde o início da epidemia, cerca de 30 milhões de pessoas morreram por causa desta doença. No entanto, as novas transmissões reduziram 19% desde 1999, alcançando a cifra de 2,6 milhões em 2009, segundo a ONUSIDA.</strong></div>
<div><strong><br />
Além disso, o acesso aos tratamentos tem aumentado: mais de 5,2 milhões de pessoas tiveram acesso a anti-retrovirais nos países em desenvolvimento, quando em 2004 não chegavam aos 700.000 beneficiários.No entanto, o director executivo da ONUSIDA, Michel Sidibé, recordou que 10 milhões de pessoas continuam à espera de um tratamento e os avanços obtidos até agora são muito frágeis devido à situação financeira mundial.</strong></div>
<div><strong><br />
Actualmente existe uma série de ferramentas para a prevenção e redução de riscos: o preservativo, tratamento de doenças sexualmente transmissíveis, conhecimento do estatuto serológico graças à detecção, à circuncisão masculina, programas de troca de seringas e meios terapêuticos de substituição da heroína para os toxicodependentes.</strong></div>
<div><strong><br />
Mas na falta de uma vacina, investigadores tentam acrescentar novos métodos a este arsenal. Um dos métodos mais promissores é a utilização dos anti-retrovirais em pessoas não infectadas. Também está a ser feita uma investigação em torno de um gel microbicida que cria uma &#8220;esperança para toda uma geração de mulheres&#8221;, segundo Sidibé.</strong></div>
<div><strong><br />
Publicado em Julho do ano passado, o estudo realizado pelo centro Caprisa em mulheres sul-africanas demonstrou que um gel vaginal microbicida à base de Tenofovir (um antirretroviral) reduz em 39% o índice de infecção sexual.Recentemente, um estudo clínico publicado no New England Journal of Medicine demonstrou que uma dose quotidiana de uma combinação de anti-retrovirais, tomados por via oral, reduz em 44% o risco de infecção pelo vírus responsável pela SIDA (VIH) nos homossexuais.</strong></div>
<div><strong><br />
Investigadores franceses e canadianos também falam num tratamento &#8216;a la carte&#8217;, ou seja, administrável, quando a pessoa (homossexual masculino) for manter uma actividade sexual.Além das experiências com animais, outros dados médicos apoiam esta estratégia: desde 1994 já foram utilizados com êxito os anti-retrovirais para reduzir o risco de transmissão do vírus da mulher grávida para o seu filho e nos casos de exposição acidental ao vírus (por exemplo, usando uma agulha contaminada).</strong></div>
<div><strong><br />
Os tratamentos (triterapêuticos) que reduziram muito a mortalidade nas pessoas infectadas pelo VIH também reduzem as quantidades de vírus no sangue e no esperma, o que contribui para limitar o seu contágio.Por fim, outra boa notícia é que uma pesquisa do Instituto de Métrica e Avaliação de Saúde da Universidade de Washington revela que as nações ricas quadruplicaram o financiamento de programas de saúde nos países pobres entre 1990 e 2010, fundamentalmente graças à maior consciencialização da necessidade de lutar contra o VIH/SIDA.</strong></div>
<div><strong><br />
A SIDA, que matou 25 milhões de pessoas desde o surgimento da doença em 1981, é um dos motivos do aumento do financiamento dos países ricos para os programas globais de saúde, afirmou à AFP Chris Murray, principal autor do relatório.</strong></div>

			<content:encoded><![CDATA[<p><strong>Tópicos de Correcção: </strong></p>
<p><strong> </strong></p>
<p><strong>A. RNA, assim como algumas enzimas.</strong></p>
<p><strong>B. Na presença da transcriptase reversa, o RNA viral é copiado em DNA por um processo designado por transcrição inversa, formando uma cadeia simples de DNA complementar do RNA do vírus. A cadeia de DNA serve de molde à síntese de uma cadeia complementar, formando uma molécula de DNA em cadeia dupla, designada por provírus.</strong></p>
<p><strong>C. o DNA proviral é incorporado no genoma da célula hospedeira.</strong></p>
<p><strong>D. Uma activação do DNA proviral leva à sua transcrição, formando RNA mensageiro.</strong></p>
<p><strong>E. Algumas moléculas de RNA vão constituir o RNA viral enquanto que outras funcionam de mRNA, ligando-se a ribossomas da célula, que passam a traduzir a sua linguagem codificada numa sequência de aminoácidos que forma as proteínas do vírus.</strong></p>
<p><strong>F. Os novos vírus formam saliências à superfície da célula e separam-se, podendo infectar outras células.</strong></p>
<p><strong>G. Período que pode variar de 1 até 10 anos, </strong><strong>assintomático, pois a pessoa infectada não apresenta qualquer sintoma.  Esse período de latência do vírus é marcado pela forte interação entre o sistema imunitário e as constantes e rápidas mutações do vírus. Durante essa fase, os vírus amadurecem e morrem de forma equilibrada. </strong></p>
<p><strong>H. Para valores de linfócitos T na ordem dos 400/mm3, surgem predominantemente infecções bacterianas na pele.À medida que os níveis de linfócitos T baixam para cerca de 100/mm3, surge a tuberculose, pneumonia, diarreias. Quando os níveis são quase nulos as infecções generalizam-se.</strong><strong></strong></p>
<p><strong>I. </strong></p>
<p><strong>1. O soro é colocado em poços numa laca, onde foram previamente fixados antigénios do HIV.</strong></p>
<p><strong>2. As placas são lavadas e os anti-corpos não anti-HIV são, assim, eliminados.</strong></p>
<p><strong>3. Adiciona-se, então, anti-corpos marcados com uma enzima E e, a seguir, um substrato que cora em presença da enzima.</strong></p>
<p><strong> </strong></p>
<p><strong>J. Período que decorre entre a infecção e o aparecimento dos anticorpos.</strong></p>
<p><strong>L. </strong></p>
<ul>
<li><strong>Um teste negativo não significa forçosamente que o indivíduo está são, devido à existência da “ janela serológica”.</strong></li>
<li><strong>Em 1ª 2% dos casos, um teste pode ser falsamente positivo, porque os anticorpos virais fixados sobre a placa podem fixar anticorpos que não são específicos do HIV e dar, assim, uma reacção positiva num indivíduo que não está infectado.</strong></li>
</ul>
<p><strong>M. 2ª geração &#8211; Capacidade de identificar os antigénios que mais se ligam e provocam a reac­ção dos anticorpos do VIH. </strong></p>
<p><strong>Vantagens: redução, quer da janela serológica  de cerca de 10 a 12 semanas para perto de seis semanas, quer do número de falsos positivos.</strong></p>
<p><strong>3ª geração – Permitem detectar os anticorpos do tipo IgM, que são os que aparecem na fase mais precoce da resposta do sistema imunitário à infecção. Depois dessa fase, esses anticorpos decrescem até desaparecerem e ficam os anticorpos do tipo IgG, que são os que permanecem durante a infecção crónica.</strong></p>
<p><strong>Vantagens: redução da janela serológica, sensivelmente, até às 3-4 semanas.</strong></p>
<p><strong>4ª geração &#8211; Além dos anticorpos que revelam a infecção, pois o sistema imunitário não os produz se não houver contacto com agente infeccioso, estes novos testes têm também a capacidade de detectar o próprio antigénio do VIH, mesmo antes dos anticorpos serem produzidos. </strong></p>
<p><strong>Vantagens: para os portadores do vírus da SIDA, quer pela importância clínica do conhecimento da infecção, quer pela possibilidade de intervenção no sentido de reduzir a transmissão do vírus, na segurança das dádivas de sangue que, </strong><strong>quando rastreadas com estes testes, irão garantir uma maior segurança em possíveis futuras transfusões.</strong></p>

			<content:encoded><![CDATA[<p> Informação pode ser aplicada em biotecnologia ou medicina</p>
<p>Dados sobre genes do mexilhão podem ter aplicações práticasUm grupo de investigadores da Universidade dos Açores criou a primeira base de dados mundial sobre o transcriptoma &#8211; informação genómica expressa através de genes &#8211; do mexilhão das fontes hidrotermais, que vive em condições extremas no mar profundo. A iniciativa, liderada por um grupo de investigadores do Departamento de Oceanografia e Pescas (DOP), permitiu identificar e caracterizar os genes do mexilhão a partir da sequenciação do seu transcriptoma, estando as informações recolhidas neste estudo pioneiro a nível mundial e o primeiro realizado em Portugal num invertebrado disponíveis na internet numa base de dados denominada “DeepSeaVent”. “A criação desta base de dados é um grande salto evolutivo na investigação porque vai permitir perceber os mecanismos de adaptação do animal a condições extremas de sobrevivência”, afirmou o investigador Raul Bettencourt. A base de dados contém mais de 75 mil sequências correspondentes a todos os ARN (ácido ribonucleico) mensageiros expressos nas brânquias do animal, num determinado instante e sob determinadas condições, codificando cerca de 43 mil proteínas possíveis. Um estudo recentemente publicado na revista científica “BMC Genomics” indica que existe um “vasto potencial” para a aplicação prática destes dados, em particular a descoberta de novos genes potencialmente envolvidos nas respostas imunitárias e inflamatórias do mexilhão das fontes hidrotermais. Aplicação prática O objectivo final da comunidade científica é que estes novos conhecimentos possam vir a ser aplicados em áreas como a biotecnologia ou a medicina. Raul Bettencourt frisou não ter dúvidas de que esta base de dados possa facilitar a descoberta de novos medicamentos, mas alertou que “ainda há um longo caminho a percorrer” nesta matéria, nomeadamente a demonstração em laboratório da actividade biológica dos genes recém-descobertos com interesse biotecnológico. O mexilhão &#8216;Bathymodiolus azoricus&#8217;, que serviu de base a este estudo, vive no campo hidrotermal &#8216;Lucky Strike&#8217;, situado a cerca de 1700 metros de profundidade, na região da Crista Média-Atlântica, a 200 milhas a sudoeste da ilha do Faial, Açores. Este invertebrado conseguiu adaptar-se às condições de um meio ambiente considerado adverso, sem luz solar, com elevados níveis de pressão hidrostática e de concentração de metais pesados, sujeito a valores extremos de temperatura</p>

<h2>Investigadores portugueses elucidam<br />
paradoxo da biologia celular na «Nature»</h2>
<div>2010-09-08</div>

<p>Miguel Godinho Ferreira, investigador principal do Instituto Gulbenkian de Ciência (IGC), e a sua equipa elucidam um paradoxo com que os cientistas se deparam desde a descoberta dos telómeros (as pontas protectoras dos cromossomas), num estudo publicado na última edição da revista científica <strong>«Nature»</strong>. Quando o DNA é danificado (por radiações ou fumo de tabaco, por exemplo) os cromossomas têm tendência a partirem-se, mas essas quebras são rapidamente unidas. No entanto, estas pontas naturais nunca se unem, permitindo desta forma a correcta segregação do material genético por todas as células do nosso corpo. </em>Infelizmente, em reposta a contínuas divisões celular, os telómeros desgastam-se e esta função protectora acaba por desaparecer à medida que envelhecemos. A perda resulta na junção das pontas dos cromossomas e, consequentemente, num “caos” genético &#8211; uma causa da formação de tumores em adultos. Compreender como as pontas dos cromossomas são protegidas da reparação de DNA e como as células respondem quando se perde essa protecção irá fornecer pistas importantes para a compreensão do envelhecimento, do cancro assim como de futuras intervenções terapêuticas.</p>
<p>As células respondem a quebras no DNA com a paragem da divisão celular, permitindo a acção dos respectivos mecanismos de reparação. Se as pontas dos cromossomas fossem também reconhecidas como DNA danificado, as células estariam constantemente a tentar repara-lo, o que levaria à morte celular e mutações. Os telómeros &#8211; as capas das pontas dos cromossomas formadas por proteínas e DNA &#8211; previnem que isto aconteça.</p>
<p><strong>Modificação da histona</strong></p>
<p>Através duma série de experiências meticulosas, a equipa Portuguesa, em colaboração com investigadores da Universidade de Illinois (Chicago), descobriu que o ponto fulcral reside na modificação duma proteína, uma histona, localizada nos telómeros. As histonas estão presentes ao longo dos cromossomas ajudando a empacotar DNA e têm um papel importante na regulação da actividade de genes. Os investigadores, que usaram como organismo modelo células de levedura de cerveja Africana (S. pombe), descobriram que esta histona presente nos telómeros não possuía o sinal químico necessário para induzir a paragem da divisão celular e consequente reparação.</p>
<p>Miguel Godinho Ferreira diz: <strong>“É incrível, mas parece que a capacidade da célula distinguir entre as pontas dos cromossomas e um dano no meio da cadeia de DNA reside nesta única alteração. De facto, ao longo do genoma esta histona retém o sinal químico, daí que se ocorrerem danos no DNA em qualquer outra região dos cromossomas, estes são reparados normalmente e as quebras unidas”</strong>.</p>
<div><img src="http://www.cienciahoje.pt/files/44/44948.jpg" alt="As pontas dos cromossomas são constituídas pelos telómeros - estruturas protectoras compostas por proteínas e ADN." width="321" height="220" /> As pontas dos cromossomas são constituídas pelos telómeros &#8211; estruturas protectoras compostas por proteínas e ADN.</div>
<p>Os telómeros podem ser comparados às capas plásticas protectoras dos atacadores de sapatos: perdendo-se estas capas, os atacadores desfiam-se e vão desaparecendo. Da mesma forma, os telómeros encurtam ao longo das sucessivas divisões celulares ao longo da vida de um organismo (isto é, com o envelhecimento). Os telómeros são normalmente elongados pela enzima telomerase. Contudo, após o nosso nascimento, ela deixa de ser expressa na maior parte das células no nosso corpo.</p>
<p>Consequentemente, os telómeros vão ficando cada vez mais curtos e, ao perderem o seu o efeito protector, enviam sinais para que as células parem de proliferar e comecem a envelhecer. Para evitar este bloqueio à proliferação celular, em 85 por cento de todos os cancros, as células cancerosas reactivam a enzima perdida e desta forma conseguem continuar a dividirem-se indefinidamente.</p>
<p>Embora a reparação do DNA deva ser prevenida nos telómeros, a maquinaria de reconhecimento de quebras desempenha uma função essencial na activação da telomerase e no alongamento dos telómeros. Miguel Godinho Ferreira acrescenta que <strong>&#8220;as células eucariótas desenvolveram um mecanismo muito específico que permite recrutar e activar a telomerase enquanto todo processo de reparação ADN é impedido nos telómeros. O conhecimento dos detalhes da sua estrutura é crucial para que se compreenda a relação com o cancro, envelhecimento e outras doenças, bem como as múltiplas vias de intervenção que poderão conduzir a tratamentos mais eficazes”</strong>.</p>
<p>Continua dando particular ênfase à importância da investigação biomédica básica: <strong>“Quando Liz Blackburn, Carol Greider e Jack Szostak descobriram a telomerase e os telómeros nos anos 80, os galardoados do prémio Nobel em Fisiologia ou Medicina do corrente ano estavam longe de imaginar as implicações clínicas que estão agora a ser desenvolvidas. Tentavam ‘simplesmente’ resolver um problema académico relacionado com a síntese de novas cadeias de DNA durante a divisão celular. Da mesma forma, sentimo-nos honrados por poder agora contribuir para a elucidação deste mecanismo, mas conscientes que as implicações directas deste trabalho poderão ser visíveis só daqui a alguns anos”</strong>.</p>

<p>Adrianna Mendrek, investigadora canadiana, realizou um estudo que pode criar alguma polémica. Segundo a académica do departamento de Psiquiatria da Universidade de Montreal e do Centro de Investigação Fernand-Seguin, a virtude que os homens têm de, muitas vezes, conseguirem não pensar em nada tem uma explicação neurológica.</p>
<p>A actividade neural do cérebro, chamada de rede por defeito, é maior em pessoas do sexo feminino do que masculino, ou seja, o cérebro dos homens entra em repouso com mais facilidade.</p>
<p>A investigadora, no entanto, precisa no estudo que a descoberta surgiu por acaso, já que se dedica ao estudo da esquizofrenia e foi nesse contexto que analisou diferentes sujeitos de ambos os sexos afectados por esta doença e comparou a sua actividade cerebral.</em> Para o estudo, 42 pessoas não esquizofrénicas, de idades compreendidas entre os 25 e 45 anos, foram submetidas a uma tarefa de rotação mental, a partir de uma figura a três dimensões, enquanto a sua actividade cerebral era medida por ressonância magnética. A medida de actividade neural foi registada quando os sujeitos, de ambos os sexos, repousavam.</p>
<p>A equipa de Mendrek constatou que as mulheres se encontravam em auto-avaliação sobre aquilo que tinha acabado de fazer e a pensar naquilo que iriam realizar a seguir, já os homens apenas se distendiam e descansavam.</p>
<p>Contudo, a investigadora assume que ainda não se encontra em posição de referir que parte da pressão social ou que hormonas biológicas distinguem os dois sexos. No entanto, assume que na própria sociedade actual, as mulheres gerem mais tarefas e têm mais preocupações.</p>
<p>A equipa encontra-se ainda a medir níveis de estrogénio e testosterona, mas resta a saber quais as medidas de actividade cerebral devem exactamente ser observadas para definir uma ligação entre os papéis das hormonas e da pressão social nas mulheres em relação aos homens.</p>

			<content:encoded><![CDATA[<p><span style="color:#ff0000;"><strong><em>Clica nas ervilhas no final para veres o esquema interactivo!</em></strong></span></p>
<p><strong>Após o estudo detalhado de cada um dos sete pares de caracteres em ervilhas, </strong><strong>Mendel</strong><strong> passou a estudar </strong><strong>dois pares de caracteres de cada vez</strong><strong>. Para realizar estas experiências, Mendel usou </strong><strong>ervilhas de linhagens puras</strong><strong> com sementes amarelas e lisas e ervilhas também puras com sementes verdes e rugosas. Portanto, os cruzamentos que realizou envolveram os caracteres cor (</strong><strong>amarela e verde</strong><strong>) e forma (</strong><strong>lisas e rugosas</strong><strong>) das sementes, que já haviam sido estudados, individualmente, concluindo que o amarelo e o liso eram caracteres dominantes.</strong><strong> </strong></p>
<p><strong>Mendel então cruzou a </strong><strong>geração parental (P)</strong><strong> de sementes amarelas e lisas com as ervilhas de sementes verdes e rugosas, obtendo, </strong><strong>em F1, todos os indivíduos com sementes amarelas e lisas</strong><strong>, como os pais dominantes. O resultado de F1 já era esperado por Mendel, uma vez que os caracteres amarelo e liso eram dominantes.</strong><strong> </strong></p>
<p><strong>Posteriormente, realizou a autofecundação dos indivíduosF1, obtendo na </strong><strong>geração F2 indivíduos com quatro fenótipos diferentes</strong><strong>, incluindo duas combinações inéditas (amarelas e rugosas; verdes e lisas). Os números obtidos aproximam-se bastante da </strong><strong>proporção 9 : 3 : 3 : 1</strong><strong>.</strong><strong> </strong></p>
<p><strong>Observando-se as duas características, simultaneamente, verifica-se que </strong><strong>obedecem à 1ª Lei de Mendel</strong><strong>. Em F2, se considerarmos cor e forma, de modo isolado, permanecem as proporções de três dominantes para um recessivo. Analisando os resultados da geração F2, percebe-se que a característica cor da semente segrega-se de modo independente da característica forma da semente e vice-versa. Por isso essa lei também é conhecida como </strong><strong>Lei da Segregação Independente</strong><strong>.</strong><strong> </strong></p>
<p><strong>Agora, estude mais detalhes da 2ª Lei de Mendel clicando nas ervilhas abaixo.</strong></p>
<p><strong></strong></p>
<p><strong>Bons estudos!</strong></p>
