Microscopic, morphometric and ultrastructural analysis of anastomotic healing in the intestine of normal and diabetic rats

The purpose of this study was to investigate if experimental alloxanic diabetes could cause qualitative changes in intestinal anastomoses of the terminal ileum and distal colon in rats, as compared to controls. 192 male Wistar rats, weighing ± 300g were split into four experimental groups of 48 animals each, after 3 months of follow-up: a control group with ileum anastomoses (G1), a control group with colon anastomoses (G2), a diabetic group with ileum anastomoses (G3) and a diabetic group with colon anastomoses (G4). Animals were evaluated and sacrificed on days 4, 14, 21 and 30 after surgery, and fragments of the small and large intestine where the anastomoses were performed were removed. Samples from 6 animals from each sacrifice moment were submitted to ultrastructural analysis of the collagen fibers using a scanning electron microscope and samples from another 6 animals were submitted to histopathology and optical microscopy studies using picrosirius red-staining. Histopathological analysis of picrosirius red-stained anastomosis slides using an optical microscope at 40x magnification showed that the distribution of collagen fibers was disarranged and also revealed a delay in scar tissue retraction. The morphometric study revealed differences in the collagen filled area for the ileum anastomoses 14 days post surgery whereas, in the case of colon anastomoses, differences were observed at days 4 and 30 post surgery, with higher values in the diabetic animals. Ultrastructure analysis of the ileum and colon anastomoses using a scanning electron microscope revealed fewer wide collagen fibers, the presence of narrower fibers and a disarranged distribution of the collagen fibers. We conclude that diabetes caused qualitative changes in scar tissue as well as in the structural arrangement of collagen fibers, what could explain the reduced wound strength in the anastomosis of diabetic animals. © J.

Flower mites decrease nectar availability in the rain-forest bromeliad Neoregelia johannis

Nectarivorous flower mites can reduce the volume of nectar available to pollinators. The effects of the flower mite Proctolaelaps sp. on nectar availability in flowers of a melittophilous bromeliad Neoregelia johannis (Bromeliaceae) was evaluated in a coastal rain forest in south-eastern Brazil. In a randomized block experiment utilizing 18 flower pairs, one per bromeliad ramet, pollinators (Bombus morio) and mites were excluded, and then nectar volume, sugar concentration and sugar mass were quantified over the anthesis period. Mites significantly reduced nectar volume early in the morning (6h00-8h00), but not later (10h00-12h00). Mites decreased total volume of nectar available up to 22%. Sugar concentration in nectar was higher earlier in the morning, and decreased between 10h00-12h00. The pronounced consumption of nectar by mites during the period of higher sugar concentration reduced the total amount of sugar available to pollinators by 31%. This is the first study showing that flower mites decrease nectar rewards in a melittophilous plant. Because nectar volume by itself incompletely describes nectar production rates and the effects of nectar removal by flower mites on the availability of sugar, our study highlights the inclusion of sugar content in future studies assessing the effects of thieves on nectar production rates.

Desafios da formação docente no curso de Pedagogia: aligeiramento e pragmatismo

This paper analyzes recent policies of teacher eduation in Brazil related to the employment and professional dimmensions of the teaching career. It analyzes teacher education policies, and the guidelines established by the World Bank in the 1990s, to reform higher education in the so-called developing countries, focusing on th implementation of neolibera educational policies. These policies have produced a "new" value for educational insititutions: they are emptying schools of education; “defertilization” of schools; “deintellectualization” of the teacher profession; pauperization, fragmentation and emptying the contents teacher education programs and recontextualization of the nexus theory-practice. The reforms after the Directives and Bases of Education - Law No. 9394/1996, with respect to the education of teachers, are analyzed in relation to the process of productive restructuring. We analyze the relation between theory and practice, given the National Curriculum Guidelines for the Education Course (DCNCP, 2006), focusing on the Course of Pedagogy for the Faculty of Philosophy and Science, at the Paulista State University, Campus of Marilia. This course offers an extensive practical training, but restricted as to the academic content offered, limiting the possibilities of an in-depth training for the future teachers. Discussing these relations, this article presents the assessment of the students in the course and concludes offering perspectives for a humanizing and critical training.

Relações públicas e o planejamento estratégico nas instituições de ensino superior privadas

The society of the information brings with it a lot of changes day by day of the organizations, mainly for characterizing as a flexible society, in net and ruled in technological progress. The contemporary organizations are inserted in that reality and they need be maintained in markets more and more competitive. The Private Institutions of Higher education enter in this logic for they be organizations with lucrative ends that suffer strong influence of the external and internal atmosphere. To stand out, such Institutions need to count with a strategic administration, ruled in an own strategic planning for the branch in that acts. The professional of public relationships is shown capable to develop their main functions in such complex market. For so much it needs to participate in the global planning of the Private Institutions of Higher education, at the same time in that it develops it planning of the communication, intrinsic to the global strategic planning. This way, the present study treats of the professional's of Public Relationships possible contributions, ruled in theoretical data, inside of Private Institutions of Higher education in the Brazilian current scenery
