A desidratação osmótica de filés de mapará tem sido utilizada como pré-tratamento antes da secagem e refrigeração de alimentos como um meio de reduzir a umidade dos produtos. O objetivo do trabalho foi otimizar a transferência de massa ocorrida durante a desidratação osmótica de mapará através da metodologia de superfície de resposta. A desidratação osmótica foi realizada de acordo com um planejamento fatorial completo 23, com oito pontos fatoriais, três centrais e seis axiais, totalizando 17 ensaios, em que o valor das variáveis dependentes, a perda de peso (PP), a perda de água (PA), o ganho de sólidos (GS), GS/PA e ácido tiobarbitúrico (TBA), são funções das variáveis independentes, temperatura, concentração de NaCl e tempo de imersão. A análise estatística aplicada aos dados experimentais foi realizada através do erro puro e pelo SS residual. Aplicando a metodologia de superfície de resposta, a condição ótima de convergência de menor perda de peso, maior perda de água e menor ganho de sal correspondeu a uma concentração de cloreto de sódio de 22%, temperatura de 46 °C e tempo de 7 horas.

Drugs commonly used in anesthesia practice may significantly alter the oxidative state of blood cells. This mechanism could contribute to the immune suppression that occurs transiently in the early postoperative period. Thus, we assessed the effects of continuous rate infusion (CRI) of propofol associated or not with tramadol on hematologic parameters in dogs. Eight adult mongrel dogs were anesthetized on 2 occasions, 15 d apart. Two groups were formed: control group (CG) and tramadol group (GT). Propofol was used for induction (10mg kg-1) followed by a CRI (0.7mg kg-1minute-1). The animals were positioned in lateral recumbency and mechanically ventilated with inspired oxygen fraction of 0.6. In TG, tramadol (2mg kg-1) followed by a CRI (0.5mg kg-1minute-1) was administered in dogs. In the CG the sodium chloride (NaCl) solution at 0.9% was administered followed by its CRI, in the same volume that was used in TG. The measurement was taken before anesthesia induction (Tbasal), 30 minutes after induction (T0) and then at 30-minute intervals (T30 to T60). Red blood cells, hematocrit, hemoblogin concentration and total leukocytes count decreased from T0 in both groups. In TG, lymphocytes count at Tbasal [1.86 (0.82) x103µl-1] was greater than at T0, T30 and T60 [0.96(0.50), 0.92(0.48) and 0.95(0.48) x103µl-1, respectively]. No significant differences were observed for platelets neutrophil, eosinophil, basophil and monocyte count. In dogs, propofol-anesthesia associated or not with tramadol promoted decrease in blood cell count and should be used with caution in immunossupressed patients.

The objective of this work was to evaluate the germination and vigor of two lots of gherkin seeds in different osmotic potentials using polyethylene glycol (PEG 6000) and sodium chloride (NaCl). Seeds of the 'North' cultivar were sown in germitest paper moistened in solutions of polyethylene glycol and sodium chloride in osmotic potentials of 0, -0.3, -0.6 and -0.9MPa. The experimental design was completely randomized in a factorial 2x4 design (solutions x osmotic potential), with four replications. Seed vigor was evaluated by the germination test, first germination count, length and dry weight of root and hypocotyl. It is concluded that the reduction in osmotic potential from -0.3MPa induced by PEG 6000 and NaCl reduces the germination and vigor of gherkin's seeds. The osmotic stress induced by PEG 6000 produced more severe effects than saline in physiological quality of gherkin's seeds.

The major aim of this study was to evaluate the inbreeding (F), average relatedness coefficient (AR) and effective population size (Ne) in the Jaffarabadi buffalo breed from Brazil. Pedigree information of 1,272 animals born from 1966 was used. The effective population size was calculated in two ways: first, computed via individual increase in inbreeding and second estimated by individual increase in coancestry. The known generation numbers were 1.24, 1.76 and 2.64 for complete, equivalent and maximum generation, respectively. The effective size computed via individual increase in coancestry was small with a value of 10.82 +/- 1.29. The effective size computed by individual increase in inbreeding (10.40 +/- 3.69) was very similar but a little smaller than the previous reported value. The average values of F and AR for the population reference (1,059) were 4.22 and 12.5 percent. The mean of F for inbred animals (319) was 14.0%. The F and AR means were 5.7 and 13.3% for animals with at least 1.5 known equivalent generation and 9.3 and 15.97% for individuals having at least 2.5 equivalent generations known. It was found 78 matings between half sibs (6.14%) and 67 matings (5.27%) between parent-offspring. The estimated inbreeding increase per generation by considering maximum generation, complete generation and equivalent generation were 1.21%, 5.18% and 3.57%, respectively. Considering the uncompleted pedigree, the estimated inbreeding for the reference population could be underestimated.
