Interação fungo micorrízico arbuscular e adubação fosfática no crescimento e absorção de nutrientes pelo porta-enxerto limoeiro Cravo

Estudou-se o efeito da inoculação com fungo micorrízico arbuscular (FMA), Glomus etunicatum, Glomus clarum, ou Scutelospora heterogama, e da adição de fósforo solúvel (15, 30, 45, 60, 120 e 240 mg de P kg-1 de terra) sobre as variáveis altura, número de folhas, diâmetro do caule, massas vegetais aérea e radicular, teores de nutrientes nas folhas e colonização micorrízica no porta-enxerto limoeiro Cravo (Citrus limonia (L.) Osbeck). Os FMAs, Glomus etunicatum e Glomus clarum, e doses crescentes de fósforo exerceram efeitos significativos sobre essas variáveis. O efeito da inoculação sobre as variáveis de crescimento vegetal foi mais acentuado nos tratamentos com adição de 30 a 60 mg de P kg-1 de terra. Para o teor de P foliar, o efeito da inoculação foi mais acentuado nos tratamentos adicionados de 120 a 240 mg de P kg-1 de terra. A inoculação com estes FMAs aumentou a eficiência do limoeiro Cravo em absorver nutrientes, tanto que as variáveis estudadas em plantas inoculadas na ausência de adubação fosfática superaram às de plantas não inoculadas em substrato adicionado de 240 mg de P kg-1 de terra.

Síndrome urêmica em cães com doença renal crônica

Uremic syndrome, arising from kidney malfunction, consists of a set of systemic changes caused by the accumulation of toxic substances to the body. Since, with the advance of medicine, the animals lived more reaching advanced age and entering thus on track of senility, chronic renal disease, became a common complaint in the routine of the ambulatory. This high rate of morbidity generates an increased need for clarification of pathophysiology involved in this disease. The components of the uremic syndrome include water and sodium imbalance, anemia, intolerance to carbohydrate, neurological disorders, disorders of the gastrointestinal tract, osteoarthritis, immunological incompetence and metabolic acidosis. The clinical manifestations occur in isolation or in combination. In most cases canines patients are subject to an assessment when the kidney disease has evolved to the final stage with uremic syndrome and installed already, under these conditions, the prognosis is reserved

Apocinina versus diapocinina como inibidor da produção de peróxido de hidrogênio e ácido hipocloroso por neutrófilos ativados

Apocynin has been used as an efficient inhibitor of the multi-enzymatic complex NADPH oxidase in many experimental models involving phagocytic and nonphagocytic cells. The mechanism of inhibition has been linked with the previous activation of apocynin through the action of cellular peroxidases leading to the formation of a dimeric oxidation product, diapocynin. In this study we compared apocynin with pure diapocynin regarding their effects as scavenger of hydrogen peroxide and hypochlorous generated by glucose/glucose oxidase and myeloperoxidase respectively, and as inhibitors of the production of hydrogen peroxide and hypochlorous acid by activated neutrophils. The production of hydrogen peroxide was measured by the oxidation of the fluorescent substance Amplex Red and the production of hypochlorous acid by was measured as taurine-chloramine derivative using the chromogenic substrate 3,3’,5,5’- tetramethylbenzidine (TMB). Neutrophils (1 x106 cells/mL) were pre-incubated in PBS buffer supplemented with 1 mM calcium chloride, 0.5 mM magnesium chloride, 1 mg/mL glucose and 5 mM taurine in the presence or absence of inhibitors. The reactions were triggered by adding the soluble stimulus Forbol Miristate Acetate PMA or zymosan and incubated by additional 30 minutes. We found that pure diapocynin was not better than apocynin regarding its scavenger and inhibitory properties. These results suggest that the formation of diapocynin is not essential for the action of apocynin as inhibitor of NADPH oxidase activation

Caracterização morfológica e fenotípica de leveduras do gênero Cryptococcus com ênfase na pesquisa de Cryptococcus neoormans isoladas de amostras de água de mar e areia de três ambientes costeiros do estado de São Paulo: Canal de São Sebastião, Baixada Santista e Ubatuba

The yeast Cryptococcus neoformans is the etiologic agent of cryptococcosis, an infectious cosmopolitan disease that affects humans. Although rare, this disease is potentially fatal, especially for immunocompromised hosts. This pathogen is frequently isolated from excrements of pigeons and parrots, with many environmental sources such as birds, pigeon droppings, eucalyptus leaves, decaying trees, towers, churches and places of storage of grain (the port area). The isolation of this microorganism has been obtained also from the aquatic environment. The identification of environmental sources is needed to protect human health, especially susceptible populations such as immunocompromised. Therefore, this study investigated the presence of Cryptococcus neoformans in yeast isolates obtained from samples of sea water and sand from three regions of São Paulo: São Sebastião Channel, Santos and Ubatuba. Isolates were analyzed according to micro-and macroscopic characteristics and biochemical tests: microculture, urease, ink nankin, auxanograma, zymogram and phenol. We analyzed 199 isolates, 175 of which had features suggestive for Cryptococcus spp. in microculture. All these 175 isolates were sown in the Christensen urea middle to verify the production of urease and submitted to the technique nankin ink to visualize the capsule. Of these, only 24 were selected for the next test that was the auxanograma (assimilation of carbohydrate and nitrogen). Of the 24, 10 were tested in zymograms (fermented sugar), from which 5 were selected for the phenoloxidase test in medium containing dopamine. None of the 5 isolates tested had black or brown color characteristic of Cryptococcus neoformans. According to these tests, we arrived at 5 isolates identified to the genus Cryptococcus, but not the neoformans specie

Avaliação da fermentação aeróbia para produção de etanol a partir da xilose por linhagem de leveduras isoladas da casca de uva (Vitis spp)

Isolate microorganisms that fermenting xylose to ethanol is a challenge to expand production of biofuels from lignocellulosic materials. For this work was tested fermentation of xylose by yeast strains isolated from grape skins (Vitis spp) in order to ethanol produce. The yeasts were grown in submerged fermentation with xylose as a carbohydrate source. Aliquots were taken every 24 hours to measure cell growth, sugar consumption and ethanol production. The yeast had an production ethanol average of 2.5 g / L and yield (Ye / s) 0.12 g / g, showing that they have the ability to produce ethanol from xylose.
