Obtenção e caracterização de nanocelulose a partir de fibras de Chorisia speciosa St. Hil

Natural fibers have been highlighted as a renewable material that can replace materials from oil and its derivatives. In this context, Brazil becomes the perfect setting because of the diversity of fibers found in its territory, such as sugarcane, sisal, rice, cotton, coconut, pineapple, among others. The paineiras (Chorisia speciosa St. Hil) are typically Brazilian trees, which produce paina as fruit. These fruits are still little studied as a source of lignocellulose by research groups. This project aimed obtaining and characterization of cellulose nanofibers from the fibers from the paina fibers. Obtaining nanocellulose is practically made through simplified chemical processes. First, was performed out pre-treatments to removal of waxes, lignin and hemicellulose. The first stage of pre-treatment was carried out by alkaline aqueous solution of sodium hydroxide (NaOH) at 5wt%, where the fibers were under constant agitation for 1h at 70°C. Through alkali treatment it was possible to remove most of the lignin, hemicellulose, waxes and extractives. After the alkaline treatment was done bleaching with an aqueous solution of sodium hydroxide (NaOH) to 4wt% and hydrogen peroxide (H2O2) to 24wt% 1:1 during 2h with constant stirring to 50 °C. Through bleaching was possibe to remove residual lignin, and got cellulose with 72% of crystallinity. Nanocellulose of paina fibers was extracted using different conditions of acid hydrolysis with sulfuric acid (H2SO4) to 50wt%. After acid hydrolysis, the suspensions were centrifuged during 30 min and dialyzed in water to remove excess acid until neutral pH (6-7). Then the suspensions were passed by ultrasonification in an ultrasound 20 kHz during 1h in an ice bath. Untreated, alkalinized and bleached fibers as well as cellulose nanoparticles were characterized by the techniques of thermogravimetry ... (Complete abastract click electronic access below)

Diferentes fontes e níveis de selênio sobre a imunidade humoral de frangos de corte

The use of organic trace minerals is getting strength and is an alternative to increase production and improve other characteristics such as humoral immunity. The present study was conducted to evaluate the effect of different levels and sources of selenium (Se) on humoral immunity of broilers. A six-week research was conducted using 1440 one-day-old males broiler chickens. The experimental design was randomized with six experimental diets (A: 0.15mg kg(-1) inorganic (inorg.); B: 0.15mg kg(-1) organic; C: 0.15mg kg(-1) inorg. + organic; D: 0.45mg kg(-1) inorganic; E: 0.45mg kg(-1) organic; F: 0.45mg kg(-1) inorg. + organic) calculated to provide the described amount of Se. Each diet was replicated in six box with 40 birds. A 3x2 factorial arrangement was used and the data were analyzed by ANOVA. The immunity was evaluated by means of the reaction against vaccine of Newcastle disease, and a reaction against sheep red blood cells (SRBC). No significant effects were observed at 5% significance level in NewCastle antibody (P >0.05). However at 14 day-old the source factor had p value at 0.0580, that show a trend of inorganic source in prolong the maternal immunity. No effect was observed in the immune response against SRBC (P >0.05). The results showed a immunologic response against Newcastle vaccine and SRBC, but the treatments was not able to induce a significant difference. The source and the level of Se showed no effect on the response against Newcastle vaccine and SRBC.

Avaliação da reprodutibilidade das medidas da camada de fibras nervosas retiniana e da cabeça do nervo óptico pela tomografia de coerência óptica

OBJETIVO: Determinar a reprodutibilidade da espessura da camada de fibras nervosas da retina peripapilar e dos parâmetros da cabeça do nervo óptico em olhos normais, utilizando a tomografia de coerência óptica de domínio espectral (SD-OCT). MÉTODOS: Trinta e quatro olhos de 34 indivíduos saudáveis foram incluídos no estudo. O protocolo do cubo do disco óptico 200x200 do OCT Cirrus foi utilizado para gerar 3 imagens de cada olho para avaliar a reprodutibilidade. O coeficiente de correlação intraclasse (ICC) foi calculado para as medidas da espessura da camada de fibras nervosas da retina e da cabeça do nervo óptico. RESULTADOS: A correlação foi excelente para todas as medidas da espessura da camada de fibras nervosas da retina (ICC entre 0,87 e 0,98). O mesmo ocorreu com os parâmetros da cabeça do nervo óptico que, com exceção da razão E/D vertical (ICC 0,56), apresentou ICC entre 0,83 e 0,99. CONCLUSÃO: As medidas de espessura da camada de fibras nervosas da retina peripapilar e os parâmetros da cabeça no nervo óptico demonstraram uma excelente reprodutibilidade com o OCT Cirrus, indicando que este aparelho poderá ser uma ferramenta útil no estudo do glaucoma. Este estudo apresenta algumas limitações, como o pequeno número de casos avaliados, sendo necessários maiores estudos para corroborar nossos achados.

Tumor misto de células musculares lisas e do estroma endometrial uterino: relato de caso

Os tumores mistos de células musculares lisas e do estroma endometrial uterino, caracterizados pela presença de componentes de ambas as linhagens, coexistindo em proporções quase equivalentes, são neoplasmas raros. Possuem potencial biológico incerto e se comportam de acordo com o componente estromal. A imuno-histoquímica é uma grande aliada no diagnóstico microscópico, pois a clínica e os exames de imagem não ajudam a diferenciá-los de outras doenças uterinas. Descrevemos o caso de uma paciente cuja hipótese diagnóstica era de leiomioma uterino e que, após cirurgia, foi diagnosticada pelo estudo anatomopatológico como tumor misto de células musculares lisas e do estroma endometrial uterino.
