Influência do ambiente de nidificação sobre a taxa de eclosão, a duração da incubação e a determinação sexual em Podocnemis (Reptilia, Podocnemididae) no Tabuleiro do Embaubal rio Xingu, Pará

Nos quelônios, as características do ambiente de nidificação têm forte influência sobre a temperatura de incubação dos ovos e, consequentemente, sobre o sucesso reprodutivo. Foram investigados o efeito do ambiente de nidificação sobre a taxa de eclosão, a duração de incubação e a determinação sexual dos filhotes de Podocnemis expansa, Podocnemis unifilis e Podocnemis sextuberculata no Tabuleiro do Embaubal, rio Xingu, estado do Pará, Brasil, em 2007, 2008 e 2010. As praias foram monitoradas entre setembro e janeiro, com o acompanhamento dos ninhos marcados desde o dia de postura, em cada ciclo reprodutivo. As seguintes variáveis foram mensuradas: dia da desova, a profundidade final, a altura do ninho em relação ao nível da água no dia da desova a granulometria e a temperatura de incubação. A taxa de eclosão diferiu entre os anos para as três espécies. A duração de incubação variou entre anos apenas para P. sextuberculata. A razão sexual de P. expansa em 2007 foi 0.08 e em 2008 e 2010 todos os filhotes produzidos foram fêmeas. Para P. sextuberculata a razão sexual em 2007 foi 0.34, e em 2008 e 2010 foi 0.06. A razão sexual de P. unifilis em 2007 foi de 0.41, 0.65 em 2008 e 0.02 em 2010. Todas estas diferenças foram estatisticamente significativas. A altura do ninho com relação ao nível do rio apresentou correlação positiva com a taxa de eclosão das três espécies em 2008 e uma relação negativa com a taxa de eclosão de P. sextuberculata em 2010. O número de dias após o início das desovas influenciou a duração de incubação de P. sextuberculata e P. unifilis em 2008. A temperatura média, o número de horas/grau acima de 32°C e o tamanho do sedimento influenciou a razão sexual de P. expansa. Os resultados atestam para a variação no sucesso de eclosão, no desenvolvimento embrionário e na proporção sexual produzida entre os anos. Ainda, observou-se que a influência de variáveis microclimáticas dos sítios selecionados para desova, embora influenciem nas características térmicas e nas variáveis de interesse, podem variar de ano para outro. Recomenda-se o monitoramento continuado dos referidos parâmetros nas principais áreas onde se investe na proteção de sítios reprodutivos de quelônios.

A leitura na perspectiva de Bakhtin e suas possibilidades na formação do leitor: na educação infantil e no primeiro ano do ensino fundamental

Overall, in Brazilian schools, the concept of reading does not take into account its possibilities and its meaning for life. But read is assigning meaning to something , make sense, interact with the text read. Thus, the present study addresses the mechanical reading, that without contextualization, performed on a technique by joining letters and syllables loose and also reading social use, consisting of statements, dialogism , polyphony and heteroglossy. It is known that the mechanical reading brings undesirable consequences, including learning problems, such as lack of attention, concentration, memory, imagination. When the reading is taught in a systematic way, with only the goal of the code decoding of written language, destroys social perspectives and intellectual development. It is common, when you offer the children a book, there the difficult disinterest of textual interpretation, because there is no attribute meaning to the content, and even the ability to interact with the text. With the interest in studying the dialogic reading this and the statements and genres, the present study was based on several authors: Bakhtin (1988, 2000), Schneuwly and Dolz (2000), Faraco (2009) and Ponzio (2009) Jolibert (1994), Bajard (2002; 2007) Foucambert (1997) Martins ( 1985) and Smith ( 1999). Aim for this study the following research question: what are the contributions of Mikhail Bakhtin's theory to the teaching of reading from kindergarten through the first grade of elementary school? Our hypothesis is that if they are guaranteed to pre -school and elementary school beginners diversified materials and new approaches in teaching reading and encouragement to her, will be developed in children a taste for the act of reading, so that they can assign meaning and significance, making reading part of their lives...

Programa Minha Casa Minha Vida: estratégia no enfrentamento da crise de 2008

This work aims to present an analysis of the Minha Casa Minha Vida, proposed by Lula's government in 2009, highlighting their main impacts for the country in the period following the international financial crisis of 2008, in addition to demonstrating the perception of different inserted agents in context. We argue that the Program implementation was a strategy for the country to overcome the crisis, moving the economy to stimulate consumption, investment and job creation. This work also analyzes the Lula government, responsible for program implementation, and seeks to show its characteristic points that led to the success of the Minha Casa Minha Vida. Finally, we demonstrate that the 2008 crisis has a side still little explored, that goes beyond the economic data that generated and can be regarded as the mainstream economic thinking crisis

Titia vem cá ver a pedra alumiante que o papai trouxe'. História da Ciência, Radioatividade e o Césio-137 em Goiânia: propostas para uma unidade didática

This study aimed to discuss the recent contributions of History of Science to theteaching of chemistry. The theme of the teaching unit was on the accident of cesium-137 in Goiânia ? Goiás, Brazil (1987). This was a qualitative study in which researcherand professor use the methodology of teaching on research.

Students producedposters in an exhibition at the school on the twentieth anniversary of the accident.Results demonstrated the importance of this resource. It was possible to exploit theabundance of detail and illustrations utilized what themes they students considerimportant and which they exploited. A poster exhibition on the theme indicated thestrong interest of students to participate in all activities proposed. The study alsorevealed the importance of using elements of the History of Science in ChemicalEducation and its relationship to the daily life of students.Key words: history of science; radioactivity; cesium-137

Immunohistochemical expression of Rho GTPases in ameloblastomas

Rho GTPases are proteins that regulate cell cycle, shape, polarization, invasion, migration, and apoptosis, which are important characteristics of normal and neoplastic cells. Rho GTPases expression has been reported in normal tooth germ and several pathologies; however, it has not been evaluated in ameloblastomas. The aim of this study was to analyze the expression and distribution of RhoA, RhoB, Rac1, and Cdc42 Rho GTPases in solid and unicystic ameloblastomas. Three-micrometer sections from paraffin- embedded specimens were evaluated by using an avidin- biotin immunohistochemical method with antibodies against the proteins mentioned above. RhoA and RhoB staining was observed in a high number of cells (P < 0.05) and greater intensity in non-polarized ones. Rac1 was not observed, andCdc42 didnot showany statistical differences between the number of non-polarized and basal positive cells (P > 0.05). Upon comparing the studied ameloblastomas, a higher number of positive cells in the unicystic variant was observed than that in the solid one (P < 0,05). The results obtained suggest that theseGTPases could play a role in the ameloblastoma neoplastic epithelial cell phenotype determination (polarized or non-polarized), as well as in variant (solid or unicystic) and subtype (follicular or plexiform) determination. Furthermore, they could participate in solid ameloblastoma invasion mechanisms. J Oral Pathol Med (2012) 41: 400-407

Uso de substâncias na adolescência e problemas familiares

Esta pesquisa visou a avaliar a associação entre o consumo de substâncias (álcool, tabaco e drogas ilícitas) e problemas familiares numa amostra de 965 adolescentes em 50 escolas públicas de dois municípios do Estado de São Paulo, Brasil, em 2007. Foi utilizado o Drug Use Screening Inventory (DUSI) para a coleta de dados. O uso de álcool, tabaco e drogas ilícitas foi associado à avaliação negativa da relação familiar, à falta de suporte/monitoramento e ao uso de substâncias por familiares (p < 0,05). Os estudantes que relataram ter feito uso de substâncias apresentaram mais problemas familiares do que aqueles que não consumiram nenhuma substância (p < 0,001). Os adolescentes que usaram álcool e tabaco (p = 0,028) e drogas ilícitas (p < 0,001) relataram ter mais problemas familiares do que aqueles que usaram apenas álcool. Os resultados apontam para a importância de se ficar atento ao consumo de álcool e tabaco entre os adolescentes, já que o relato do consumo das duas substâncias esteve associado a prejuízos familiares significativos, semelhantes ao uso de drogas ilícitas.

Sjuksköterskans förhållningssätt vid omvårdnad av patient med akut smärta

Abstrakt Bakgrund: Smärta är ett fenomen som upplevs olika, alla individer som någon gång drabbas av smärta reagerar olika starkt. Hur individen tolkar och bemästrar smärtupplevelsen är beroende av vilken ålder, kön, kulturell och social bakgrund de tillhör. Syftet med denna litteraturstudie var att belysa om sjuksköterskans förhållningssätt och patientens upplevelse av bemötandet vid ett akut smärttillstånd. Metod: Studien är baserad på fjorton artiklar från 2002-2007 och vi har funnit dom i databaserna PubMed och Cinahl. Resultat: Snabb identifiering av smärta är viktigt vid behandling av smärta. För att behandlingen skall bli så god som möjligt är dialogen mellan patient och sjuksköterska viktig. Utbildning samt rutin har visat sig vara till stor fördel vid behandling då hela patienten är i fokus och inte endast symtomet. Smärtinstrument är bra som hjälpmedel vid behandling av smärta men bör vara ett komplement till patientens verbala beskrivning av tillståndet. Konklusion: Efter en sammanställning av denna studie kan det konstateras att kommunikation och smärtlindring samt vårdpersonalens attityder påverkar människor som drabbats av tillståndet akut smärta

Accuratezza nella diagnosi prenatale di malformazione fetale

OBJECTIVE: One major problem in counselling couples with a prenatal diagnosis of a correctable fetal anomaly is the ability to exclude associated malformations that may modify the prognosis. Our aim was to assess the precision of fetal sonography in identifying isolated malformations. METHODS: We retrospectively reviewed the prenatal and postnatal records of our center for cases with a prenatal diagnosis of an isolated fetal anomaly in the period 2002-2007. RESULTS: The antenatal diagnosis of an isolated malformation was made in 284 cases. In one of this cases the anomaly disappeared in utero. Of the remaining cases, the prenatal diagnosis was confirmed after birth in 251 (88.7%). In 8 fetuses (7 with a suspected coarctation of the aorta, 1 with ventricular septal defect) the prenatal diagnosis was not confirmed. In 24 fetuses (8.5%) additional malformations were detected at postnatal or post-mortem. In 16 of these cases the anomalies were mild or would not have changed the prognosis. In 8 cases (2.8%) severe anomalies were present (1 hypoplasia of the corpus callosum with ventriculomegaly, 1 tracheal agenesis, 3 cases with multiple anomalies, 1 Opitz Syndrome, 1 with CHARGE Syndrome, 1 COFS Syndrome). Two of these infants died. CONCLUSIONS: the prenatal diagnosis of an isolated fetal anomaly is highly reliable. However, the probability that additional malformations will go undetected albeit small remains tangible. In our experience, it was 2.8%.

Ärztliche Haltung zur Komplementärmedizin in der Region Burgdorf

Hintergrund: Komplementärmedizinische Methoden sind in der Schweiz seit langem sehr beliebt. Gemäss den Schweizerischen Gesundheitsbefragungen 2002/2007 lassen sich mehr als 30% der Bevölkerung über 15 Jahren innerhalb eines Jahres komplementärmedizinisch behandeln. Auf Lebensfrist steigt diese Zahl auf 63.4%. Eine aktuelle Untersuchung der KIKOM zeigt, dass ca. 30% der befragten Grundversorgern in der ganzen Schweiz mehr als einmal pro Woche von Patienten nach Komplementärmedizin gefragt werden. Dieselbe Studie zeigt, dass ein Grossteil der befragten Grundversorger selber Komplementärmedizin anbieten oder Patienten für komplementärmedizinische Behandlungen überweisen. Zur Einstellung von Ärzten gegenüber Komplementärmedizin existieren viele Studien. Kaum untersucht ist bisher, ob und wie sich die Haltung von Spitalärzten und zuweisenden Ärzten nach Einrichtung eines Ambulatoriums/Konsiliartätigkeit mit Komplementärmedizin ändert. Fragestellung Wie ist die Haltung gegenüber Komplementärmedizin bei den Ärzten in der Region Burgdorf (Spital Burgdorf, zuweisende Ärzte) vor der Einrichtung einer Sprechstunden-/Konsiliartätigkeit von drei komplementärmedizinischen Methoden (Akupunktur/TCM, Anthroposophische Medizin, Klassische Homöopathie) am Spital Burgdorf und wie ist die Haltung nach einem Jahr und nach zwei Jahren? Methode: Mittels eines Fragebogens werden Meinung und Entschiedenheit dieser Aussage gegenüber Komplementärmedizin und ganzheitlichem Heilungsverständnis erfasst. Der Fragebogen steht Online zur Verfügung und wird zusätzlich allen Ärzten per Post zugeschickt. Die erste Befragung Ende 2010/Anfangs 2011 dient der Erhebung der Ausgangsdaten vor der Aufnahme der Sprechstundentätigkeit. In jährlichen Abständen wird die Umfrage wiederholt. Ergebnis: Von 170 verschickten Fragebogen wurden 6 nicht zugestellt. Lediglich 5 Teilnehmer haben den Fragebogen online ausgefüllt. 43 Fragebogen kamen spontan zurück. Nach telefonischem und schriftlichem Reminder konnten nochmals 26 Fragebogen eingeholt werden. Die Rücklaufquote beträgt damit 45% (74 von 164). Die weiteren Resultate sind in der Auswertung und werden im August zur Verfügung stehen.

Risk attribution of Campylobacter infection by age group using exposure modelling

Knowledge on the relative importance of alternative sources of human campylobacteriosis is important in order to implement effective disease prevention measures. The objective of this study was to assess the relative importance of three key exposure pathways (travelling abroad, poultry meat, pet contact) for different patient age groups in Switzerland. With a stochastic exposure model data on Campylobacter incidence for the years 2002-2007 were linked with data for the three exposure pathways and the results of a case-control study. Mean values for the population attributable fractions (PAF) over all age groups and years were 27% (95% CI 17-39) for poultry consumption, 27% (95% CI 22-32) for travelling abroad, 8% (95% CI 6-9) for pet contact and 39% (95% CI 25-50) for other risk factors. This model provided robust results when using data available for Switzerland, but the uncertainties remained high. The output of the model could be improved if more accurate input data are available to estimate the infection rate per exposure. In particular, the relatively high proportion of cases attributed to 'other risk factors' requires further attention.
