3. Salmonellosis in calves without intestinal lesions
RESUMO: A salmonelose é uma causa conhecida de distúrbios entéricos em bezerros. Porém, casos na forma septicêmica podem não apresentar manifestação entérica, o que leva o médico veterinário a não suspeitar de salmonelose, comprometendo o diagnóstico. Este estudo descreve os aspectos epidemiológicos, clínicos, patológicos e imuno-histoquímic

4. RED WINE EXTRACT OBTAINED BY MEMBRANE-BASED SUPERCRITICAL FLUID EXTRACTION: PRELIMINARY CHARACTERIZATION OF CHEMICAL PROPERTIES.
ABSTRACT This study aims to obtain an extract from red wine by using membrane-based supercritical fluid extraction. This technique involves the use of porous membranes as contactors during the dense gas extraction process from liquid matrices. In this work, a Cabernet Sauvignon wine extract was obtained from supercritical fluid extraction using pressurized c

5. Bacteriemia por Ralstonia pickettii en pacientes en hemodiálisis: reporte de dos casos
ABSTRACT Ralstonia pickettii is a low-virulence gram-negative bacillus that may be associated with infections related to health care and may cause bacteremia. Ralstonia pickettii bacteremia is uncommon but is related to the contamination of medical products, mainly in immunodepressed patients. We present two cases of patients on chronic hemodialysis with Ral

6. Anti-inflammatory effects of intravenous methotrexate associated with lipid nanoemulsions on antigen-induced arthritis
OBJECTIVE: To test the hypothesis that intravenous use of methotrexate associated with lipid nanoemulsions can achieve superior anti-inflammatory effects in the joints of rabbits with antigen-induced arthritis compared with commercial methotrexate. METHODS: Arthritis was induced in New Zealand rabbits sensitized with methylated bovine serum albumin and sub

7. Changes in maternal body composition and metabolism of dairy goats during pregnancy
The objective of this study was to evaluate the mobilization of nutrients in goats of different gestation types and pregnancy stages. Forty-four Saanen and Oberhasli goats were studied. The goats of each breed and gestation type (single or twin) were slaughtered at different gestational ages (80, 110, and 140 days of pregnancy), forming a completely randomiz

8. Structural and fluid dynamic characterization of calcium carbonate-based porous ceramics
The aim of this work was to experimentally evaluate the use of calcium carbonate as a pore-generating agent in ceramic compositions. Compositions that contained 50% kaolin, 20% limestone, and different concentrations of quartz and feldspar were prepared by uniaxial pressing. Samples were heat-treated at a heating rate appropriate to induce calcium carbonate

9. Fases de membranas fluidas -L3 a partir de lipídio sintético e pentanol na região diluída - e o respectivo dialisado / Phases membrane fluid - L3 from synthetic lipid and pentanol and diluted in the region corresponding dialyzed
A fase L3 (esponja) foi observada no final dos anos 80 e representa uma nova classe de auto moldagem para sistemas surfactantes em água. Esse trabalho descreve a descoberta e a posterior caracterização de uma fase ternária composta do lipídio sintético catiônico brometo de dioctadecildimetil amônio (DODAB), pentanol e água, em uma região diluída.

11. Produção de agua de coco (cocus nucifera) utilizando membranas de micro e ultrafiltração de celulose, PES e PVDF / Coconut water processing using micro and ultrafiltration membranes of cellulose, PES and PVDF
Coconut water is a natural drink. Lately, its consumption has been growing in both natural form and processed form, because of the coconut water health benefits. Processing methods are used, essentially, to inhibit the enzymes actions (polyphenoloxidase and peroxidase) that are responsible for coconut water color chage to rose and ensure its microbiological

12. Estudo do desempenho do processo de microfiltração tangencial com membranas cerâmicas aplicado à retenção de bactérias e redução de sólidos suspensos de uma bebida à base de açaí / Performance study of the crossflow microfiltration process with ceramic membranes applied to the bacteria retention and suspended solids reduction of the beverage based on açai
In this doctoral research, the crossflow microfiltration process utilizing ceramic membranes was investigated aiming at the bacteria retention (Escherichia coli) and reduction of suspended solids of beverage based on açai (Euterpe oleracea Mart.). The selected commercial membranes of alfa-alumina (AL IND.2O IND.3) had nominal pore sizes of 0.8 and 1.2 müm
