Abstract: purpose: to investigate whether the alterations of the diverted colon segment mucosa, evidenced in fecal colitis, would be able to alter bacterial translocation (bt). methods: sixty-two wistar male rats ranging from 220 to 320 grams of weight, were divided in two groups: a (colostomy) and b (control), with 31 animals each one. in group a, all animals underwent end colostomy, one stoma, in ascending colon; and in the 70th pod was injected in five rats, by rectal route diverted segment - 2ml of a 0.9% saline solution in animals (a1 subgroup); in eight it was inoculated, by rectal route, 2ml of a solution containing escherichia coli atcc 25922 (american type culture collection), in a concentration of 108 colony forming unit for milliliters (cfu/ml) - a2 subgroup; in ten animals the same solution of e. coli was inoculated, in a concentration of 1011 cfu/ml (a3 subgroup); and in eight it was collected part of the mucus found in the diverted distal colonic segment for neutral sugars and total proteins dosage (a4 subgroup). the animals from the group b underwent the same procedures of group a, but with differences in the colostomy confection. in rats from subgroups a1, a2, a3, b1, b2, and b3 2ml of blood were aspirated from the heart, and fragments from mesenteric lymphatic nodule, liver, spleen, lung and kidney taken for microbiological analysis, after their death. this analysis consisted of evidencing the presence of e. coli atcc 25922 cfu. mann-whitney and anova tests were applied as analytic techniques for association of variables. results: the occurrence of bt was evidenced only in those animals in which inoculated concentration of e. coli atcc 25922, reached levels of 1011cfu/ml, i.e. in subgroups a3 and b3, although, being significantly greater (80%) in those animals without colostomy (subgroup b3) when compared to the ones with colostomy (20%) from the subgroup a3 (p <0.05). lung, liver and mesenteric lymphatic nodules were the tissues with larger percentile of bac

Abstract: the objective of this study was to evaluate the photographic and radiographic classification agreement of the two main types of class ii subdivision malocclusions. the sample consisted of 44 untreated class ii subdivision malocclusion subjects with a mean age of 15.3 years. all possessed a full complement of permanent teeth up to the first molars and had not been submitted to orthodontic treatment. frontal photographic evaluation was performed by means of a subjective evaluation by two examiners. type i class ii subdivision malocclusion presents a coincidence of the maxillary dental midline with the facial midline and a deviation of the mandibular midline. type ii presents the opposite characteristics. evaluation of the posteroanterior radiographs was performed by one examiner and the dental midline deviation was evaluated in relation to the x line. agreement between the two classification methods was evaluated by the kappa coefficient.although results demonstrated a tendency of similar distribution for both types of class ii subdivision malocclusion in photographic and radiographic evaluation, agreement between these two methods of evaluation was not statistically significant.

Abstract: alfred russel wallace traveled through the amazon from 1848 to 1852. his perceptions of the region were informed by his systematized knowledge but also influenced by judgments of an ethical and aesthetic nature, as was common among naturalists. he saw the region's 'natives' as peaceful and friendly but likewise susceptible to the vices of civilization. nature afforded a privileged setting both for the activities of natural history and for aesthetic pleasures. these features helped keep the naturalist in the region, where he could thus engage in his scientific activities.
Adaptability, Entrepreneurship and Stakeholder Integration: Scenarios and Strategies for Environment and Vulnerability  [PDF]
Jerónimo De-Burgos-Jiménez, Diego A. Vazquez-Brust, José A. Plaza-úbeda
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.210160
Abstract: The “vicious circle” between poverty and environmental deterioration is a major challenge for those developmental approaches which look to improve the welfare of vulnerable communities. Environmental deterioration increases poverty while, at the same time, poverty causes further environmental deterioration as the business activities which communities depend upon for survival aggravate environmental deterioration by causing pollution and waste. It is therefore necessary that firms and communities collaborate in order to develop innovative solutions to break this vicious circle. This paper argues that such collaboration should be based on genuine stakeholders’ integration and entrepreneurship, proposes a holistic framework to guide business intervention strategies, and further explores collaboration scenarios between firms and communities.

Abstract: the objective of this work was to evaluate the influence of stocking density on growth, feed conversion ratio and survival of juvenile common snook (centropomus undecimalis). fish were collected from the wild and trained to accept artificial diets. individuals (13±0.4 cm and 23±0.3 g) were stocked into nine 5-m3 circular fiberglass tanks at three different densities: 3, 6 and 9 fish/m3 during a period of 180 days. tanks were supplied with seawater and continuous aeration. total ammonia-nitrogen (0 to 0.5 mg/l), water temperature (23.3 to 30.6oc), salinity (17 to 34 g/l), ph (7.8 to 8.4) and dissolved oxygen concentration (4.8 to 6.9 mg/l) were similar in all tanks. feed conversion rate (1.88, 2.06 and 2.31) and survival (100%, 98.9% and 96.3%) were significantly improved for fish stocked at the lower densities (3 and 6/m3). there were significant differences in average weight (110, 87 and 80 g) and length (20, 18.5 and 18 cm) among treatments. fish stocked at the lowest density (3/m3) showed the highest growth rate, and there was no difference between the others. however, final biomass (332, 511 and 703 g/m3) was directly correlated with density. a low density influences positively growth, survival and feed conversion in common snook rearing.

Abstract: O objetivo deste trabalho foi analisar a influência da densidade de estocagem no crescimento, convers o alimentar e sobrevivência de juvenis de robalo-flecha (Centropomus undecimalis). Os peixes foram coletados em ambiente natural e treinados a aceitar dietas artificiais. Os indivíduos, com comprimento total de 13±0,4 cm e peso de 23±0,3 g foram estocados em tanques circulares de fibra de vidro de 5 m3, com água do mar e aera o contínua, nas densidades de 3, 6 e 9 peixes/m3, por 180 dias. Os valores de am nia total (0 a 0,5 mg/L), temperatura da água (23,3 a 30,6oC), salinidade (17 a 34 g/L), pH (7,8 a 8,4) e oxigênio dissolvido (4,8 a 6,9 mg/L) apresentaram padr o similar entre os tratamentos. A convers o alimentar (1,88, 2,06 e 2,31) e a sobrevivência (100%, 98,9% e 96,3%) foram significativamente melhores nos tratamentos com 3 e 6 peixes/m3. As médias finais de peso (110, 87 e 80 g) e comprimento total (20, 18,5 e 18 cm) apresentaram diferen a significativa. A maior taxa de crescimento foi observada com 3 peixes/m3; entre as demais n o houve diferen a. Entretanto, a biomassa final (332, 511 e 703 g/m3) foi diretamente proporcional à densidade. A baixa densidade favorece o cultivo do robalo em rela o ao crescimento, sobrevivência e convers o alimentar.
