Antonio José Balloni, Adalberto Mantovani Martiniano de Azevedo, Marco Antonio Silveira
Open Journal of Political Science (OJPS) , 2012, DOI: 10.4236/ojps.2012.23004
Abstract: Abstract: This paper explores the challenges and expresses some reflections on information and Knowledge/Wise (KW) societies and Socio-technical Systems (SS) based on an Organizational Eco-systems (ECOs) approach. It considers the SS constituting KW societies as a set of heterogeneous and interactive actors and presents considerations on the challenges faced by an organizational Ecosystem (ECO), challenges that require organizations actions towards treatment of organizations as living beings inserted in ECOs, aiming to leverage organizational synergism and collaborative efforts; information partnership and collaborative relationships between ECOs members; a more fairly shared leadership, empowering bottom up processes on organizational ECOs decision making. It is presented a brief case regarding Brazil’s Public Research and Development arrangement “National Institute of Science and Technology in Micro and Nano-electonic Systems” (NAMITEC), relating this initiative advances and problems in terms of multi-organizational cooperation and transference of technological knowledge to the productive sector and to society.

Silva, Adalberto Ferreira da;Aguilar-Nascimento, José Eduardo de;
Revista do Colégio Brasileiro de Cirurgi?es , 2001, DOI: 10.1590/S0100-69912001000300010
Abstract: background: aerobic flora is associated with bacterial translocation (bt). the anaerobic flora may have a role in the occurrence of this phenomenon. the aim of this study was to investigate the effect of metronidazol on the intestinal morphology and on the occurrence of bt in the presence or absence of intestinal obstruction. methods: eighty wistar rats were randomized to two groups: group metronidazol (n=40) and group saline (n=40). they received the correspondent medication for 72h. each group comprised four subgroups of 10 rats each as follows: without laparotomy, with laparotomy, ileal and sigmoideal obstruction. after receiving the solutions for 48h, the rats underwent different operative procedures depending on the subgroups except for subgroup without laparotomy in which no operation was carried out. they were killed after 72h and the mesenteric lymph nodes, liver, spleen and blood samples were cultured. biopsies of the jejunum, ileum and sigmoide were collected and sent to histomorphometric measurements. results: a significantly higher mortality was observed in group saline in obstructed animals. there was no important morphological differences between the groups. in metronidazol group the incidence of bt (8/40; 20%) was significantly higher (p =0.028) than in controls (1/40; 2,5%) in non-operated animals. in the subset of ileum obstruction, the rate of bt was higher in controls than in metronidazol group (27/40; 67,5% vs. 7/40; 17,5%; p<0.001). however, there was greater translocation to lymph nodes in metronidazol group compared with controls in sigmoid obstructed rats. conclusions: metronidazol favors the occurrence of bt under basal conditions. there is no important morphological alteration induced by metronidazol. intestinal obstruction enhances bt and the site of obstruction influences the rate of translocation associated with metronidazol. however, mortality is lower when metronidazol is used in obstructed animals.

Abstract: Se realizó un estudio descriptivo de la totalidad de las colectas de células progenitoras hematopoyéticas realizadas en el Banco de Sangre del Hospital "Hermanos Ameijeiras" desde abril del 2001 hasta abril del 2002, mediante leucoféresis. Se utilizó un equipo de flujo continuo (FRESENIUS ASTEC 204) y se empleó el programa mononucleares con el set P1Y. Se determinó peso, talla, hematócrito, hemoglobina, conteo de leucocitos y plaquetas de los donantes previo a la colecta. En el producto de la leucoféresis se analizó el conteo de leucocitos con diferencial, conteo de células CD34+/ CD45+ (mediante técnica de inmunofluorescencia en citómetro de flujo) y determinación de viabilidad celular con yoduro de propidio en este mismo equipo (Facscan, Becton Dickinson). Recibieron trasplante autólogo 5 pacientes y 2 trasplantes alogénicos. Los primeros con diagnósticos de: linfoma no hodgkiniano (3), enfermedad de Hodgkin (1), artritis reumatoidea (1); y los segundos afectados de leucemia mieloide crónica (1) y linfoma no hodgkiniano (1) ; todos ellos atendidos en el Servicio de Hematología de nuestro centro. La media del conteo de células CD34+ por cada leucoféresis para trasplante autólogo fue 2,4 x 106 Kg y en el alogénico 2,96 x 106 Kg . Los resultados evidencian que mediante el ajuste del volumen de los ciclos, la velocidad centrífuga, el volumen de rebosado y el volumen celular, se obtuvo un conteo de células precursoras hematopoyéticas en la colecta similar a lo reportado por otros autores, lo que garantiza que el producto transfundido cuente con la celularidad necesaria para repoblar la médula ósea, luego que el paciente sea tratado con altas dosis de terapia inmunosupresora y/o radiaciones A descriptive study of all the collections of hematopoietic progenitor cells obtained by leukophoresis at the Blood Bank of "Hermanos Ameijeiras" Hospital from April, 2001, to April, 2002, was conducted. A continual flow equipment (FRESENIUS ASTEC 204) was used and the mononuclear program with the P1Y set was applied. Weight, height, haematocrit, haemoglobin, leukocyte and platelet count of the donors were determined before the collection. In the product of the leukophoresis, the leukocyte count with differential, the CD34+/CD45+ cells count (by immunofluorescence technique in flow cytometer) and the determination of cellular viability with propidium iodide in this equipment (Facscan, Becton Dickinson), were analyzed. 5 patients recieved autologous transplantations and 2 allogeneic transplantations. The first were diagnosed non-Hodgkin lymphoma (3), Hodgkin disease (1),

Abstract: Background Emerging evidence has shown that miRNAs are involved in human carcinogenesis as tumor suppressors or oncogenes. Single nucleotide polymorphisms (SNPs) located in pre-miRNAs may affect the processing and therefore, influence the expression of mature miRNAs. Previous studies generated conflicting results when reporting association between the hsa-miR-196a2 rs11614913 common polymorphism and breast cancer. Methods This study evaluated the hsa-miR-196a2 rs11614913 SNP in 388 breast cancer cases and 388 controls in Brazilian women. Polymorphism was determined by real-time PCR; control and experimental groups were compared through statistical analysis using the X2 or Fisher’s exact tests. Results The analysis of the SNPs frequencies showed a significant difference between the groups (BC and CT) in regards to genotype distribution (χ2: p = 0.024); the homozygous variant (CC) was more frequent in the CT than in the BC group (p = 0.009). The presence of the hsa-miR-196a2 rs11614913 C/T polymorphism was not associated with histological grades (p = 0.522), axillary lymph node positive status (p = 0.805), or clinical stage (p = 0.670) among the breast cancer patients. Conclusions The results of this study indicated that the CC polymorphic genotype is associated with a decreased risk of BC and the presence of the T allele was significantly associated with an increased risk of BC.
