Orientador: Ana Cláudia Figueiredo Frizzo / Resumo: Introdução: O Zica vírus tornou-se uma epidemia no Brasil a partir do início de 2015, tendo os primeiros casos de microcefalia com suspeita de causa pelo Zica Virus confirmados nos estados do Rio Grande do Norte e Pernambuco. Desde então, pesquisas evidenciam a necessidade de maiores investigações acerca da fisiologia dos indivíduos afetados pela doença, sintomas e prognósticos a fim de aprimorar o tratamento das crianças com a chamada “síndrome congênita do zica vírus”. Desta forma, para estudar e minimizar os impactos que uma possível alteração no córtex auditivo possa acarretar no desenvolvimento comunicativo destas crianças, este estudo tem como objetivo principal descrever os valores do potencial cortical auditivo de crianças que provavelmente foram infectadas pela síndrome congênita do Zica vírus. Métodos: Trata-se de um estudo multicêntrico, transversal descritivo, o qual foi desenvolvido no Setor de Audiologia do Centro de Estudos da Educação e da Saúde (CEES), da Universidade Estadual Paulista (UNESP), e na Universidade Estadual de Ciências da Saúde de Alagoas – UNCISAL, Laboratório de Audiologia do Centro Especializado em Reabilitação (CER III), com aprovação no comitê de ética CAAE nº 68684117.8.1001.5406. Participaram do estudo 30 crianças, de ambos os gêneros, de seis a 38 meses de vida, compondo o grupo estudo, com microcefalia e provável síndrome congênita do zica vírus e grupo controle, nos quais foram realizados exames de potencial evocado auditivo cortical e...

Since then, research has shown the need for further research into the physiology of individuals affected by the disease, symptoms and prognosis in order to improve the treatment of children with the so-called congenital zygote virus syndrome. Thus, in order to study and minimize the impacts that a possible alteration in the auditory cortex may have on the communicative development of these children, this study has as main objective to describe the cortical auditory potential values of children who were probably infected by the congenital syndrome of Zika virus. Methods: This is a multicenter, cross-sectional descriptive study, which was developed in the Audiology Sector of the Center for Education and Health Studies (CEES), Universidade Estadual Paulista (UNESP), and at the State University of Health Sciences of Alagoas - UNCISAL, Audiology Laboratory of the Specialized Center for Rehabilitation (CER III), with approval in the ethics committee CAAE nº 68684117.8.1001.5406. The study consisted of 30 children of both genders, from six to 38 months of age, making up the study group, with microcephaly and probable congenital syndrome of the virus zika and control group, in which cortical auditory evoked potential tests were performed in children with development....

Objetivo: analisar a distribui??o temporo-espacial das taxas de incid?ncia de anomalias cong?nitas no Rio Grande do Norte, antes e ap?s a epidemia v?rus da zica atrav?s de uma an?lise geoestat?stica e correla??o com os determinantes sociais em sa?de M?todos: trata-se de um estudo epidemiol?gico do tipo ecol?gico, retrospectivo que avaliou os casos notificados de anomalias cong?nitas no Rio Grande do Norte agrupando em dois bi?nios (2005-2006 e 2015-2016), configurando per?odos antes e ap?s a epidemia de zica atrav?s de uma an?lise espacial, cujos dados obtidos do DATASUS e da Secretaria Estadual de Sa?de, foram agrupados no SPSS 13.0 e analisados no Terraview vers?o 4.2.2. Resultados: a taxa de anomalias cong?nitas no per?odo pr?-Zica foi de 11,83 casos/1.000 nascidos vivos e no per?odo p?s-Zica aumentou para 14,24 casos/1.000 nascidos vivos, resultado do aumento dos casos notificados. Foi observada que a mesorregi?o Agreste Potiguar ? a que possui maior n?mero de casos notificados de Zica assim como ? a regi?o que concentra maior n?mero de casos de anomalias cong?nitas no per?odo estudado, estando correlacionada com regi?o com grandes dicotomias sociais. Conclus?es: o presente parece revelar que as anomalias cong?nitas sempre estiveram presentes no estado e nenhuma outra a??o foi suscitada com tamanha import?ncia como no per?odo Zica. Estrat?gias para minimizar os casos de anomalias cong?nitas atrav?s de a??es de planejamento familiar, controle da idade materna, programas de vacina??o, controle na venda de medicamentos abortivos, combate ao consumo de drogas, ?lcool e fumo podem facilmente ser desenvolvida e ganhar ades?o midi?tica, fato que nem sempre ? percebido, tendo a m?dia dado um enfoque ao aumento dos casos de notifica??o sem buscar entender o processo. / Introduction: although the media coverage provides certainty of a relationship between the Zika virus and microcephaly in newborns, which is an increase in the grouping of congenital anomalies in the Brazilian Northeast, it is suggested that the incidence of congenital anomaly in Rio Grande do Sul North isn?t different when compared to its spatial distribution before and after Zika, because factors such as environmental, socioeconomic and biological can contribute to the permanence of a high incidence in the state. The objective of the present study is to analyze the temporal-spatial distribution of the incidence rates of congenital anomalies in Rio Grande do Norte, before and after the epidemic virus Zika through a geostatistical analysis and correlation with the social determinants in health. Methods: this is an ecological that evaluated the reported cases of congenital anomalies in Rio Grande do Norte before and after the Zika epidemy through a spatial analysis, whose data were grouped in SPSS 13.0 and analyzed in Terraview version 4.2.2. Results: the rate of congenital anomalies in the pre-Zika period was 11.83 cases / 1.000 live births and in the post Zika period it increased to 14.24 cases/1.000 live births, a result of the increase in reported cases. It was visualized that the Agreste Potiguar mesoregion is the one with the highest number of reported cases of Zika, as it is the region that concentrates the largest number of cases of congenital anomalies in the period studied, being correlated with the region with great social dichotomies. Conclusion: the present study revealed that congenital anomalies were always present in the state and no other action was raised with such importance as in the Zika period. Strategies to minimize cases of congenital anomalies through family planning actions, maternal age control, vaccination programs, control in the sale of abortive drugs, drug, alcohol and tobacco use can easily be developed and gain media adherence, fact which is not always perceived, the media having given a focus to the increase of the cases of notification without seeking to understand the process.

O objetivo deste trabalho foi avaliar o efeito de inoculantes de isolados de Pisolithus sp. na produ??o de mudas de clones de Corymbia pela miniestaquia, em condi??es de viveiro. Os clones de Corymbia AEC0007, AEC0022, AEC0043 e AEC0045 inoculados com os isolados de Pisolithus sp. C9C, C16 com a mistura dos dois isolados (MIX = C9C+C16), foram crescidos em substrato com redu??o da aduba??o fosfatada. Como controle, os mesmos clones, n?o inoculados, foram crescidos em substrato com (Controle) e sem (Comercial) redu??o da aduba??o fosfatada. A sobreviv?ncia das mudas nos clones AEC0007 e AEC0043 n?o foi influenciada pela inocula??o. Para os demais clones, as mudas inoculadas com C16 foram at? 75 % maiores que as mudas do Comercial. A inocula??o com MIX aumentou a altura das mudas do AEC0007, AEC0043 e AEC0045, todos em rela??o ?s mudas do Comercial e do Controle. O C16 aumentou o di?metro das mudas do AEC0007 e AEC0045 em at? 25 % em rela??o ?s do Comercial, e para os demais clones, a inocula??o n?o teve influ?ncia. As maiores porcentagens de coloniza??o foram observadas nas mudas do AEC0007, AEC0022 e AEC0043 inoculadas com C9C e com MIX. A inocula??o, em geral, aumentou a frequ?ncia de torr?es firmes e parcialmente enraizados e firmes e bem enraizados, exceto para o AEC0045. Os teores de P, N, K, Ca e Mg estavam abaixo do considerado ideal e os teores de Zn e Fe estavam acima da faixa adequada. Apenas os teores de Mn permaneceram dentro da faixa considerada adequada. As porcentagens de pontas colonizadas se correlacionaram positivamente com par?metros de crescimento e nutri??o nos clones AEC0007, AEC0022 e AEC0043, mas a quantidade de par?metros e a intensidade da correla??o foram dependentes do clone. A inocula??o com Pisolithus sp. aumenta a coloniza??o ectomicorr?zica e o crescimento de mudas Corymbia em viveiro comercial, mas isto ? dependente do clone e do isolado. Os inoculantes mais promissores foram MIX> C9C>C16, pois promoveram maiores crescimento, sobreviv?ncia, massa seca, coloniza??o e qualidade de torr?es das mudas de Corymbia. O clone AEC0043 foi o mais responsivo ? inocula??o por fungos ectomicorr?zicos, obtendo maiores benef?cios. / Disserta??o (Mestrado) ?

The objective of this work was to evaluate the effect of inoculants of Pisolithus sp. in the production of mini-cuttings of Corymbia clones, under nursery conditions. The Corymbia clones AEC0007, AEC0022, AEC0043 and AEC0045 inoculated with the isolates of Pisolithus sp. C9C, C16 with the mixture of the two isolates (MIX = C9C + C16) were grown on substrate with reduction of phosphate fertilization. As a control, the same uninoculated clones were grown on substrate with (Control) and without (Commercial) reduction of phosphate fertilization. The survival of the mini cuttings in clones AEC0007 and AEC0043 was not influenced by inoculation. The survival of the AEC0022 mini-cuttings inoculated with C16 was 75% greater than those from the commercial, but this effect was dependent on the isolate and the clone. The inoculation with the MIX increased the height of the mini-cuttings of AEC0007, AEC0043 and AEC0045, all in relation to the Commercial and Control mini-cuttings. The C16 increased the diameter of the AEC0007 and AEC0045 mini-cuttings by up to 25% compared to the Commercial ones and for the other clones inoculation it had no influence. The highest percentages of colonization were observed in the AEC0007, AEC0022 and AEC0043 mini-cuttings inoculated with C9C and MIX. The inoculation, in general, increased the frequencies of firm and partially rooted and firm and well rooted clods, except for AEC0045. The concentration of P, N, K, Ca and Mg were below the ideal level and the Zn and Fe concentration were above the appropriate range. Only Mn concentration remained within the range considered adequate. The percentages of colonized tips correlated positively with growth and nutrition parameters in clones AEC0007, AEC0022 and AEC0043, but the number of parameters and the intensity of the correlation was dependent on the clone. The inoculation with Pisolithus sp. increases ectomycorrhizal colonization and growth of Corymbia mini-cuttings in commercial nursery, but this is dependent on the clone and isolate. The most promising inoculants were MIX> C9C> C16, as they promoted greater growth, survival, dry mass, colonization and quality of clods of Corymbia mini-cuttings. Clone AEC0043 was the most responsive to inoculation of ectomycorrhizal fungi, obtaining greater benefits.

The efficiency of doses of inoculant of EMF to promote growth, nutrients absorption, ectomycorrhizal colonization and clonal seedlings quality of Eucalyptus urophylla in commercial plant nursery were assessed on this study. The crop fertilization of the substrate of production of seedling was reduced at 50 per cent to avoid inhibitory effect of crop fertilization on ectomycorrhizal colonization. The experiment was made in completely randomized design in 4x4-factorial scheme, with four doses of inoculum compounded with vegetal mycelium impregnated by calcium-alginate gel (0, 5, 10 and 15 capsules) of EMF Amanita muscaria isolated UFSC-Am161, Elaphomyces anthracinus (Cenococcum geophilum) isolated Amance, Pisolithus microcarpus isolated ITA-06 and Scleroderma areolatum isolated UFSC-Sc129, plus a non-inoculated control with a hundred per cent of fertilization of the substrate with four repetitions. The EMF, in general, promoted bigger diameter of the base, height of aerial part, dry matter of aerial part, ectomycorrhizal colonization, concentration and leaf content of N, P and K on clonal seedling of eucalyptus. The best growth and colonization were observed at the highest dose of the inoculant and the highest levels and contents of P, N and K at a dose of 10 capsules of inoculant. The Dickson Quality Index was not influenced by different fungi and doses of inoculum. The clonal eucalyptus seedling inoculated by the EMF and that was grown with half substrate fertilization, despite of less production of dry matter, show concentration and content of P and N and concentration of K bigger or equal to those seedling that was grown with the fertilization of substrate of production of seedlings of complete and non-inoculated. They also submit sufficient quality for transplantation as early as 90 days.

The objective of this study was to evaluate the application of glycerin, a biodiesel industry waste, came from vegetable oil transesterification of triglycerides by potassium hydroxide catalyst (KOH) as a source of potassium ("K glycerin") on productivity and nutrition of soybeans and on chemical and microbiological characteristics of the soil. Two experiments were conducted under field conditions in a Oxisol (Typic) soil type, at Curvelo, Minas Gerais state, Brazil, and another in the village of Diamantina, Minas Gerais state in a sand soil type (NQ). The experimental design was randomized blocks with four replications. The treatments were three doses of "glycerin K 'corresponding to 50, 100 and 200% of recommended dose of Potassium for soybean and 100% of the dose recommended in the form of KCl and K2SO4 and a treatment without application of K. The recommended dose of K2O were 120 and 80 kg ha -1 for NQ and Oxisoil, respectively. There has been carried out chemical analysis of soil (pH, P, K, Ca, Mg, Al, Al + H, CO, SO4-2) in the soybean harvest and microbiological analysis (microbial basal respiration (BR), microbial biomass carbon (CBM) and metabolic quotient (OKQ (2)) soil at two times (early emergence and soybean harvest) and soybean yield and foliar concentrations of nutrients in the flowering of soybeans. Soybean yield increased with the application of "glycerin K" when the availability of K in the soil was limited, and although lower than the mineral sources of K, it supplied in part the soybeans need for K. The soil microbiota tended to balance at the end of the cycle of soybeans with application of "glycerin K", thus not causing adverse effects on crop and soil. The "glycerin K" does not cause environmental problems to the place where it was applied, but studies are needed to evaluate its long-term use to better understand the dynamics of soil and crop productivity.

Within this frame fits the group Pitadenia encompassing genres: Mimosa , Piptadenia , Parapiptadenia , Anadenathera , Pseudopiptadenia , Microlobius , Stryphnodendron and Adenopia , comprising over 500 species, of which most are found in the New World , especially in Brazil . Their habits vary from tree and herbaceous species to thrive in flooded, dry, high altitude grasslands , savanna ecosystems among other areas . Are well known and used in the rehabilitation of degraded soils by their aggressiveness and ability to grow under adverse soil conditions. Results indicate that in some species of this group only nodulated with the presence of mycorrhizal fungi. Legumes use for the realization of these two symbioses very similar molecular mechanisms and some of leguminous species from the subfamily Mimosoideae show atypical and high potential exploration of evolutionary symbiosis between the two skills. The objective of this work is to investigate and confirm this dependence of the presence of arbuscular mycorrhizal fungi for nodulation and nitrogen fixation in species group Piptadenia nodulated by Burkholderia sp . under controlled conditions / A fam?lia Leguminosae compreende um imensa variedade de esp?cies que formam simbiose com fungos micorr?zicos arbusculares (FMAs) e, em sua grande maioria, com bact?rias fixadoras de nitrog?nio. Dentro desse quadro se encaixa o grupo de Pitadenia que engloba os g?neros: Mimosa, Piptadenia, Parapiptadenia, Anadenathera, Pseudopiptadenia, Microlobius, Stryphnodendron e Adenopia, compreendendo mais de 500 esp?cies, sendo que a maioria delas ? encontrada no novo mundo, em especial no Brasil. Seus h?bitos variam desde esp?cies herb?ceas at? arb?reas e se desenvolvem em ?reas alagadas, secas, campos de altitude, cerrado entre outros ecossistemas. S?o bem conhecidas e utilizadas na reabilita??o de solos degradados por sua agressividade e capacidade de se desenvolver nas mais adversas condi??es ed?ficas. Resultados indicam que em algumas esp?cies desse grupo s? nodulariam com a presen?a de fungos micorr?zicos. As leguminosas usam para a realiza??o dessas duas simbioses mecanismos moleculares muito similares e algumas dessas esp?cies de leguminosas nativas da subfam?lia Mimosoideae mostram habilidades at?picas e com alto potencial de explora??o evolucion?ria entre as duas simbioses. O objetivo deste trabalho ? investigar e confirmar essa depend?ncia da presen?a de fungos micorr?zicos arbusculares para a nodula??o e fixa??o biol?gica de nitrog?nio em esp?cies do grupo de Piptadenia noduladas por Burkholderia sp. sob condi??es controladas
