Chronic low back pain is a difficult condition to be treated. As some patients respond positively to treatment and others do not present any improvements, one can think there are others conditional factors that need to be elucidated. By means of this study, we sought to investigate the association between the occurrence of the formation of a positive relationship between patient and therapist, assessed by the therapeutic alliance inventory, and the adequate recruitment of the deep abdominal muscles, as well as to verify the effect of a protocol intervention based on motor control exercises on levels of pain and disability. The recruitment of the transverse abdominal and internal oblique muscles was examined by ultrasound imaging in 12 subjects with nonspecific chronic low back pain before and after implementation of a protocol for motor control exercises, with subsequent application of the therapeutic alliance inventory questionnaire. No association was found between the level of therapist/patient alliance and muscle recruitment. The proposed protocol was effective in reducing the levels of pain and disability; however, recruitment of transverse abdominal and internal oblique muscles showed no significant changes in the end of the intervention. Based on these findings, we verified that the therapeutic alliance has no association with muscle recruitment in the short term. However, although there were no changes in muscle recruitment after the intervention program, the level of pain and disability was reduced.

The aim of this study was to detect the expression of ciclooxigenase-2 (COX-2) in metastatic primary carcinoma and non metastatic carcinoma, taking into consideration the relation between COX-2 and the progression of cancer. Evaluation of the COX-2 expression was achieved by immunohistochemistry analysis, using the primary polyclonal antibody anti-PGHS-2, clone PG 27, (Oxford Biomedical Research). The number of marked cells by the COX-2 antibody was higher (P < 0.001) in the metastatic primary carcinoma (81.25%) than non-metastatic (60.3%). There was a positive correlation between the number of labeled cells.

Forty eight piglets from a commercial strain weaned at an average age of 21 days were used in order to evaluate effects of carbohydrates sources (lactose or maltodextrin) and the weights of piglets at weaning on the stomach pH, colon and rectum contents, and the amount of total coliform, Escherichia coli and Lactobacillus spp in digesta of ileum and cecum. The experiment was conducted in a randomized block design and analyzed in split plot, considering class of weight and carbohydrates as main plots and the slaughter age of animal as sub-plots. The stomach pH and intestinal contents were not influenced by the diets provided as well as the amount of total coliform. It was found that the presence of lactose in the feed decreased counts of Escherichia coli and Lactobacillus ssp in the ileum. Regarding the class of weight, the lighter piglets had lower counts of Escherichia coli and Lactobacillus. The maltodextrin can be used as an alternative to replace the lactose in the diet, regardless of the piglets weight at weaning, as it does not adversely affect the pH and the Lactobacillus population in the gastrointestinal tract.

As xilanases são enzimas que hidrolisam as ligações 1,4-β-xilosídicas da xilana e que possuem potencial biotecnológico em vários processos industriais, como na clarificação de sucos e vinhos, na fabricação de pães, na produção de biocombustíveis e no tratamento das polpas celulósicas. Além disso, os produtos de hidrólise da xilana, xilooligossacarídeos, podem ser utilizados como ingredientes prebióticos, ou seja, ingredientes nutricionais não digeríveis que estimulam seletivamente a proliferação e a atividade de bactérias benéficas do cólon. O uso de enzimas microbianas nas indústrias se dá devido às suas diversas vantagens sobre os métodos químicos e à facilidade de obtenção do microrganismo. Assim, os objetivos deste trabalho foram: produzir e caracterizar parcialmente a xilanase de Aspergillus sp isolado de pó de café utilizado, purificar parcialmente a enzima produzida e analisar os produtos de hidrólise da xilana. O Aspergillus sp mostrou-se bom produtor de xilanase quando o pó de sabugo de milho foi utilizado como fonte de carbono e a xilanase produzida apresentou melhor atividade específica quando o período de cultivo foi de 168 horas. Os processos de precipitação de proteínas e diálise promoveram o aumento da atividade específica do extrato. A xilanase de Aspergillus sp apresentou pH e temperatura de máxima atividade semelhantes aos de produzidas por Aspergillus niger isolados de outras fontes. A hidrólise da xilana produziu xilose e xilooligossacarídeos. Além da xilanase, o fungo revelou ser produtor de outras proteínas que podem ser estudadas em pesquisas futuras.
