Waves of Change Within Civil Society in Latin America: Mexico City and Sao Paulo

For the past half a century, Latin American scholars have been pointing toward the emergence of new social actors as agents of social and political democratization. The first wave of actors was characterized by the emergence of novel agents-mainly, new popular movements-of social transformation. At first, the second wave, epitomized by nongovernmental organizations (NGOs), was celebrated as the upsurge of a new civil society, but later on, it was the target of harsh criticism. The literature often portrays this development in Latin American civil society as a displacement trend of actors of the first wave by the second wave-""NGOization""-""and even denounces new civil society as rootless, depoliticized, and functional to retrenchment. Thus, supposedly, NGOization encumbers social change. The authors argue that NGOization diagnosis is a flawed depiction of change within civil society. Rather than NGOization related to the depoliticization and neoliberalization of civil society, in Mexico City and Sao Paulo, there has been modernization of organizational ecologies, changes in the functional status of civil society, and interestingly, specialization aimed at shaping public agenda. The authors argue that such specialization, instead of encumbering social change, brings about different repertoires of strategies and skills purposively developed for influencing policy and politics. Their argument relies on comparative systematic evidence. Through network analysis, they examine the organizational ecology of civil society in Mexico City and Sao Paulo.

Structural and electron self-exchange rate variations in isomeric (hexaamine)cobalt(III/II) complexes

The syntheses and characterisation of the new macrocyclic hexaamine trans-(5(S),7(S),12(R),14(R)-tetramethyl)-1,4,8,11-tetraazacyclotetradecane-6,13-diamine (L-6) and its Co-III complex are reported. The X-ray crystal structural analyses of [CoL6]Cl-2(ClO4) [monoclinic, space group C2/c, a = 16.468(3) Angstrom, b = 9.7156(7) Angstrom, c = 15.070(3) Angstrom, beta = 119.431(8)degrees, Z = 4] and the closely related cis-diamino-substituted macrocyclic complex [CoL2](ClO4)(3) . 2H(2)O (L-2 = cis-6,13-dimethyl-1,4,8,11-tetraazacyclotetradecane-6,13-diamine) [orthorhombic, space group Pna2(1), a = 16.8220(8) Angstrom, b = 10.416(2) Angstrom, c = 14.219(3) Angstrom, Z = 4] reveal significant variations in the observed Co-N bond lengths and coordination geometries, which may be attributed to the trans or cis disposition of the pendent primary amines. The Co-III/II self-exchange electron transfer rate constants for these and other closely related hexaamines have been determined, and variations of some 2 orders of magnitude are found between pairs of trans and cis isomeric Co-III complexes.

Treadmill running protects spinal cord contusion from secondary degeneration

It is known that physical activity triggers changes in the central nervous system Adult rats, trained on treadmills for 4 weeks, and a group of sedentary rats was submitted to contuse moderate spinal cord injury A group of sedentary rats was submitted to a sham operation The trained group continued running on treadmill after lesion for 4 weeks Motor behavior evaluated by BBB score was smaller in the sedentary group compared to the trained rats by 7 days after lesion Computerized activity monitor showed clear-cut differences in spontaneous motor parameters in trained rats only before lesion After surgery, sedentary rats showed changes in motor parameters but not in later periods of analysis Animals were euthanized by 28 days after surgery, and their spinal cords were processed for Nissl staining and immunohistochemistry The number of the remaining neurons and the lesion areal and lesion volume fractions were obtained by stereological method The number of the remaining neurons did not change after training Lesion volume and lesion areal fraction per section were smaller in the trained group Lesion index was more pronounced in the sedentary group Microdensitometric image analysis demonstrated a microglial reaction, astroglial activation, and glial FGF-2 production more pronounced in the spinal cord of sedentary animals GAP-43 was higher in caudal levels of contusion in the sedentary group In conclusion, treadmill running may favor a better functional recovery in the acute period after spinal cord lesion and wound repair processes leading to neuroprotection (C) 2010 Elsevier B V All rights reserved

Nutritional knowledge, eating attitudes and chronic dietary restraint among men with eating disorders

We compared nutritional knowledge, eating attitudes and chronic dietary restraint scores among 17 men (10 with bulimia nervosa and 7 with anorexia nervosa) and 50 women (20 with bulimia nervosa and 30 with anorexia nervosa), who were consecutive patients at a major treatment center in Brazil. There were no differences in nutritional knowledge and concern with food between men and women. For both genders, chronic dietary restraint scores were higher among bulimics. Men with eating disorders had better eating attitudes scores than women. Anorexic men tended to have worse eating attitudes scores than bulimic men, while the opposite was observed for women, suggesting an interaction between gender and diagnosis.

Frequency and prognostic relevance of cancer testis antigen 45 expression in multiple myeloma

Objective. This study aims to analyze the expression of cancer testis antigen 45 (CT45) in normal tissues and in plasma cell disorders and to identify possible associations with clinical data and prognosis in multiple myeloma (MM) patients. Materials and Methods. Expression of CT45 was studied in 20 normal tissues (testis, placenta, skeletal muscle, bladder, lung, spleen, heart, brain and fetal brain, thymus, uterus, stomach, mammary gland, pancreas, prostate, small intestine, kidney, adrenal gland, spinal cord, colon, and one pool of 10 normal bone marrow samples) and bone marrow aspirates from 3 monoclonal gammopathies of undetermined significance, 5 solitary plasmacytomas, 61 newly diagnosed MM patients and MM cell line U266 by reverse transcriptase polymerase chain reaction. Results. CT45 was positive in 3 of 20 (15%) normal tissues tested: lung, brain (both fetal and adult), and spinal cord. Among monoclonal gammopathies, CT45 was positive in 2 of 5 (40%) solitary plasmacytomas bone marrow aspirates, 10 of 61 (16%) MM bone marrow aspirates, and in the U266 MM cell line. Conclusions. We did not find associations between bone marrow histology and CT45 expression. However, we demonstrated for the first time that positive expression of CT45 was associated with poor prognostic (international Staging System) and poor outcomes in MM patients, meaning that CT45-positive cases presented seven times more chance of worse evolution than the negative ones.

INTERMITTENT ACTIVATION OF PERIPHERAL CHEMORECEPTORS IN AWAKE RATS INDUCES Fos EXPRESSION IN ROSTRAL VENTROLATERAL MEDULLA-PROJECTING NEURONS IN THE PARAVENTRICULAR NUCLEUS OF THE HYPOTHALAMUS

Despite the well-established sympathoexcitation evoked by chemoreflex activation, the specific sub-regions of the CNS underlying such sympathetic responses remain to be fully characterized. In the present study we examined the effects of intermittent chemoreflex activation in awake rats on Fos-immunoreactivity (Fos-ir) in various subnuclei of the paraventricular nucleus of the hypothalamus (PVN), as well as in identified neurosecretory preautonomic PVN neurons. In response to intermittent chemoreflex activation, a significant increase in the number of Fos-ir cells was found in autonomic-related PVN subnuclei, including the posterior parvocellular, ventromedial parvocellular and dorsal-cap, but not in the neurosecretory magnocellular-containing lateral magnocellular subnucleus. No changes in Fos-ir following chemoreflex activation were observed in the anterior PVN subnucleus. Experiments combining Fos immunohistochemistry and neuronal tract tracing techniques showed a significant increase in Fos-ir in rostral ventrolateral medulla (RVLM)-projecting (PVN-RVLM), but not in nucleus of solitarii tract (NTS)-projecting PVN neurons. In summary, our results support the involvement of the PVN in the central neuronal circuitry activated in response to chemoreflex activation, and indicate that PVN-RVLM neurons constitute a neuronal substrate contributing to the sympathoexcitatory component of the chemoreflex.

Giardia duodenalis: Pathological alterations in gerbils, Meriones unguiculatus, infected with different dosages of trophozoites

To examine the infection kinetics and development of alterations in the small intestine of gerbils (Meriones unguiculatus), 72 gerbils were divided into six groups (A to F), with A serving as control and the others inoculated with increasing doses of trophozoites from Giardia duodenalis human isolate. The infection kinetics and the development of histopathological alterations were monitored by optical scanning electron microscopy (SEM). A 12-day prepatent period was observed, with intermittent elimination up to day 35 after inoculation. Statistically significant differences were found between the mean number of trophozoites recovered, per group, on the days of sacrifice, and a positive correlation between the moculum dosage and the number of trophozoites recovered. Morphometrically, the villus:crypt ratio showed a drop in all the groups when compared with the control group. SEM revealed an increase in mucus production in the inoculated animals and the presence of trophozoite clusters at the top and base of the villi. The dosage of trophozoite inoculum does not interfere in the ability for infection to occur or in the development of histopathological alterations generated by intestinal colonization.

Evidence of early involvement of matrix metalloproteinase-2 in lead-induced hypertension

Lead exposure increases blood pressure (BP) by unknown mechanisms. Many recent studies have shown the involvement of matrix metalloproteinases (MMPs) in hypertension, particularly MMP-2. In this work, we have examined whether MMP-2 levels increase with lead-induced increase in BP. We have also investigated whether doxycycline (an MMP inhibitor) affects these alterations. To this end, rats were exposed to lead (90 ppm) and treated with doxycycline or vehicle for 8 weeks. Similar aortic and whole blood lead levels were found in lead-exposed rats treated with either doxycycline or vehicle. Lead-induced increases in BP and aortic MMP-2 levels (activity, protein, and mRNA) were blunted by doxycycline. Doxycycline also prevented lead-induced increases in the MMP-2/TIMP-2 mRNA ratio. No significant changes in vascular reactivity or morphometric parameters were found. In conclusion, lead exposure increases BP and vascular MMP-2, which is blunted by doxycycline. This observation suggests that MMP-2 may play a role in lead-induced increases in BP.

Contribui????es do governo eletr??nico para a reforma administrativa e a governan??a no Brasil

O artigo investiga as contribui????es da pol??tica de governo eletr??nico para a reforma administrativa e a governan??a no Brasil. A pesquisa baseou-se na opini??o de informantes-chave dos quatro setores que atuam no e-gov: setor p??blico, iniciativa privada, terceiro setor e academia. Concluiu-se que as tecnologias de informa????o e comunica????o (TIC) podem ser a principal ferramenta para as iniciativas de moderniza????o do Estado, sendo ressalvado que o e-governo n??o pode ser visto como panac??ia para as reformas: o uso de tecnologias deveria caminhar em paralelo com outras medidas governamentais, nos campos pol??tico e econ??mico, por exemplo. Embora tenha sido reconhecido o potencial das TIC, o governo eletr??nico ainda n??o se encontra inserido com a ??nfase necess??ria na agenda governamental brasileira, de modo a contribuir decisivamente para a reforma administrativa e a governan??a.

Mobilidade social e empoderamento: a percep????o das mulheres benefici??rias do programa Bolsa Fam??lia em Minas Gerais

Esse trabalho teve como objetivo analisar os efeitos relacionados ?? mobilidade social e ao empoderamento das benefici??rias do Programa Bolsa Fam??lia em Minas Gerais. Foram utilizados procedimentos metodol??gicos anal??ticos, em um estudo de caso m??ltiplo com abordagem quantitativa. Foi realizada a valida????o dos constructos de mobilidade social e empoderamento, permitindo-se mensurar a intensidade da rela????o entre essas diferentes dimens??es. Os resultados demonstram a melhoria significativa na vida das benefici??rias, o que pode possibilitar ascend??ncia social. Contudo, observou-se, como fator limitante, o baixo grau de escolaridade das benefici??rias, mostrando-se a necessidade de conex??o dos programas sociais com atividades educacionais e de gera????o de trabalho e renda, para inser????o das mulheres no mercado de trabalho. Dessa forma, considera-se que o Programa Bolsa Fam??lia pode influenciar significativamente tanto no empoderamento quanto na mobilidade social das benefici??rias. Ademais, a articula????o com atividades educacionais e produtivas pode avigorar os resultados de pol??ticas p??blicas que defendam a justi??a social e a diminui????o das desigualdades existentes entre g??neros e classes sociais.

El Cuadro de Mando Integral en Organizaciones Privadas Portuguesas: Un Análisis Descriptivo

La creencia de que los modelos existentes para evaluación del desempeño empresarial eran obsoletos y podían llevar a las empresas a tomar decisiones erróneas llevaron al desarrollo de sistemas de información y control de gestión que reflejen la evolución de los factores clave de éxito de naturaleza no financiera y/o cualitativa, como es el caso del Cuadro de Mando Integral (CMI). El CMI es una de las herramientas de Contabilidad de Gestión más populares en la actualidad. Al mismo tiempo hay informes de altas tasas de fracaso lo que exige mirar con mayor detenimiento los retos y los principales problemas que distintas organizaciones privadas han encontrado en su implementación. En consecuencia, mismo después de más de dos décadas de existencia, y a pesar de las mejoras registradas en el modelo, se verifica en el ámbito empresarial y académico una continuidad de la inversión en proyectos de CMI. Así, con el objetivo de averiguar si las organizaciones portuguesas conocen y están a adoptar el CMI, hemos enviado un cuestionario a 549 organizaciones privadas, con una tasa de respuesta del 28,2%. Los resultados obtenidos permiten concluir que aunque la mayoría de los encuestados conoce el CMI, su utilización en dichas organizaciones es reducida y muy reciente.

Regulação da contabilidade: teorias e análise da convergência dos padrões contábeis brasileiros aos IFRS

O processo de convergência das práticas nacionais de contabilidade aos padrões internacionais implica profundas alterações na regulação da contabilidade. É natural que os contabilistas estejam preocupados em se adaptar aos "novos" padrões buscando adotá-los, e auditar sua adoção nas respectivas empresas/clientes. Entretanto, tão importante quanto adotar e auditar a adoção dos International Financial Reporting Standards (IFRS) nas demonstrações contábeis das empresas brasileiras é compreender o movimento de alteração das normas contábeis em âmbito nacional. Por outro lado, pouco se tem discutido sobre os impactos dessas novas regulamentações. Este artigo analisa, numa perspectiva interdisciplinar, o processo de alteração da regulação da contabilidade à luz de cinco teorias da regulação. Embora as teorias sejam concorrentes, observou-se que elas podem ser utilizadas de forma complementar entre si na compreensão das alterações promovidas pela Lei nº 11.638/07 e pela Medida Provisória nº 449/08 na Lei nº 6.404/76. Considerou-se que as teorias realiana e habermasiana são as que melhor contribuem para a democratização da contabilidade, uma vez que consideram os valores sociais na elaboração e posterior interpretação da regulação.

Substâncias Cosmetologicamente Activas Caracterização, Indicação, Eficácia e Segurança: Cafeína

A cafeína é usada em formulações cosméticas tópicas para tratamento da Paniculopatia Esclero Edematosa (PEE), em concentrações de 1-2%, embora existam no mercado formulações com 5%. Estudos in vitro têm demonstrado que a cafeína estimula a lipólise e a redução de tamanho dos adipócitos, através do aumento dos níveis de AMPc. As características físico-químicas da cafeína dificultam a transposição da barreira cutânea, nomeadamente do estrato córneo, etapa limitante da penetração cutânea. Existem vários factores envolvidos na fisiopatologia da PEE nomeadamente genéticos, hormonais e estilos de vida, que parecem actuar em quatro unidades funcionais do tecido adiposo: unidade interstício-matricial, unidade microcirculatória, unidade neuro-vegetativa e unidade energética. Os formuladores privilegiam o desenvolvimento de formulações cosméticas tópicas, que incorporem ingredientes activos com acção sobre a estimulação do fluxo microvascular e linfático por um lado e, por outro lado, que actuem directa ou indirectamente nos mecanismos reguladores da lipólise. Desenvolvem-se formulações cosméticas tópicas, constituídas por substâncias que promovam a penetração cutâneo, e utilizam-se veículos que depositem de uma forma direccionada, e em maior quantidade os ingredientes activos no local de acção.
