Abstract: this research studied the adsorption and the desorption of the herbicide 2,4-dichlorofenoxyacetic acid (2,4-d) in soil from urbano santos - ma. the region has eucalyptus crops, and they will be used for attainment of cellulose. herbicides, namely 2,4-d, are used for clean the fields before the plantation and in the firsts 12 months. the freundlich isotherm was used as model for this study, and the 2,4-d concentration was determined through high performance liquid chromatography (hplc). this determination was studied by recoveries assays. the results suggest the 2,4-d to show bigger adsorption at organic mater of studied soil that others kinds of the soils. this can results in lower tendency of leaching and degradation, but the herbicide shows high potential of leaching when compared with others pesticides.

Abstract: A ansiedade e a preocupa o dos pacientes decorrentes da obscuridade das informa es relacionadas ao procedimento cirúrgico ortognático despertou o desenvolvimento deste estudo, que objetivou identificar as necessidades de informa o do paciente sobre o cuidado pós-operatório da cirurgia ortognática. Trata-se de pesquisa exploratória qualitativa, que utilizou como método de coleta de dados o grupo focal com pacientes em pós-operatório de cirurgia ortognática de um ambulatório de cirurgia e traumatologia bucomaxilofacial. Os dados foram submetidos à análise de conteúdo para identifica o das falas significativas para o alcance do objetivo. Entre os assuntos mais abordados, destacaram-se o longo tempo de recupera o e as dificuldades relacionadas à alimenta o, higieniza o e redu o dos sinais e sintomas pós-operatórios. Comentários relacionados à autoimagem e à satisfa o com os resultados da cirurgia apontam para a necessidade de explora o em futuros estudos. La ansiedad y la preocupación de los pacientes por la falta la información acerca de la cirugía ortognática provocaron el desarrollo de este estudio, que tuvo como objetivo identificar las necesidades de información del paciente sobre el cuidado postoperatorio. Es una investigación exploratoria cualitativa, que utilizó la técnica del grupo focal para recoger datos. Pacientes en el postoperatorio de cirugía ortognática de un ambulatorio de cirugía bucomaxilofacial y trauma fueron invitados a participar en el grupo. Los datos fueron sometidos a análisis de contenido y entre las cuestiones que se plantean más frecuentemente, se mencionó el largo tiempo de recuperación, las dificultades relacionadas con la alimentación, la higiene y la reducción de los signos y síntomas después de la operación. Comentarios relacionados con la imagen de sí mismo y la satisfacción con los resultados de la cirugía indican la necesidad de futuros estudios para explorar estos temas. Patient's anxiety and worry due to a lack of knowledge about the orthognathic surgery motivated the development of this study. The objective was to identify information needs of postoperative patient undergoing orthognathic surgery. It's an exploratory and qualitative research that used the focus group to collect the dada. Postoperative patients of orthognathic surgery from an oral and maxillofacial surgery and trauma ambulatory were invited to participate in the group. Through content analysis it was possible to identify the following problems related to the postoperative procedure: long recovery time, nutrition, oral hygiene, relief of posto

Abstract: the occurrence of autochthonous cases of chagas disease in the amazon region of brazil over recent decades has motivated an intensification of studies in this area. different species of triatomines have been identified, and ten of these have be proven to be carriers of the parasite trypanosoma cruzi or " cruzi-like " parasites. studies conducted in the municipalities of santa isabel do rio negro and barcelos, located on the upper and middle of the negro river, microregion of negro river, state of amazonas have confirmed not only that rhodnius brethesi is present in the palm tree leopoldinia piassaba, but also that this insect was recognized by palm fiber collectors. a morphological study of eyes, inter-ocular and inter-ocellar regions, antennae, buccula, labrum, rostrum, stridulatory sulcus and feet, including the apex of the tibia, spongy fossette and ctenidium was conducted by scanning electron microscopy. the buccula and the stridulatory sulcus presented notable differences in specimens of different genera and also of different species. these data make it possible to suggest that the details presented in these structures can be included as diagnostic characteristics to be used in new dichotomous keys, thereby contributing towards studies of taxonomy and systematics and furnishing backing for comparative analysis of specimens collected from different localities.
Soroprevalência da infec??o por Helicobacter pylori em crian?as de diferentes níveis sócio-econ?micos em Porto Velho, Estado de Rond?nia
Rodrigues, Rosely Valéria;Corvelo, Teresa Cristina;Ferrer, Mabel Torres;
Revista da Sociedade Brasileira de Medicina Tropical , 2007, DOI: 10.1590/S0037-86822007000500012
Abstract: this study investigated the seroprevalence of helicobacter pylori infection in 200 children in the city of porto velho, state of rond?nia, divided in two groups of 100 children. the prevalence of seropositivity varied considerably according to socioeconomic level, such that 51% of the lower-level children and 24% of the middle-class children were positive. the characteristics of the child population relating to sex, ethnicity and diet did not represent risk factors for acquiring the infection. however, most of the infected children were in the age group of five years or older, independent of socioeconomic level. the phenotypic distribution of abo blood groups among the infected and uninfected individuals showed that the seroreactivity to helicobacter pylori was greater among the children with the o blood type, thus suggesting that these children have greater genetic susceptibility to infection by helicobacter pylori.
