FEDERALISMO FISCAL E MUNICIPALIZA O: UMA RELEITURA DA TRAJETóRIA DO BRASIL
Renato Luis Pinto Miranda,Elias Rodrigues de Oliveira
Gest?o & Regionalidade , 2010,
Abstract: A literatura pertinente ao federalismo fiscal apresenta controvertidos entendimentos acerca das suas tendências de centraliza o e descentraliza o. Assim, a diversidade de critérios utilizados na avalia o destes processos desqualifica as tentativas de análise mais aprofundada da distribui o das receitas aosmunicípios. O que n o usualmente merece questionamento é se, independentemente de uma tendência à centraliza o ou descentraliza o, a estrutura federativo-fiscal está em efetiva consonancia com as reais finalidades do Estado num dado contexto sócio-histórico. Como forma de averiguar tal conformidade, aborda-se aqui a composi o da estrutura federativo-fiscal do País em face dos concomitantes objetivos estatais no período que vai de 1960 a 1973. A partir de um levantamento bibliográfico, foram selecionadosentendimentos a respeito da composi o federativo-fiscal do País no período delimitado. Constatou-se que as medidas adotadas na reestrutura o do Sistema Tributário Nacional e a correspondente conforma o federativa estavam de acordo com as finalidades do Estado na época. Sugere-se, diante disso, a observa o das reais finalidades do Estado brasileiro na atualidade (independentemente da no o de Estado adotada), para que se possa compreender a dinamica do federalismo fiscal brasileiro como uma forma de estrutura o que, de fato, atende a objetivos específicos.

Acta Cirurgica Brasileira , 2006,
Abstract: PURPOSE: Study the proliferation rate of jejunum and large intestine crypt epithelial cells, in rats pinealectomized immediately after borning. METHODS: Twenty-four male Wistar rats were distributed into two groups: Acute group (n=12) and Chronic group (n=12). Six animals of each group were operated for removal of the pineal gland (pinealectomy-PnX), and other six were controls (sham pinealectomy-C). Animals from acute and chronic group were sacrificed 15 and 90 days after the surgery, respectively. RESULTS: In acute group, pinealectomy of new-born rats has not caused significant alteration in cell proliferation (PnX=58,77?1,77 and C=60,88?1,10 in the descending colon/ PnX=31,56?0,45 and C=31,73?0,47 in the proximal jejunum) and in crypt cell population (PnX=24,92?4,82 and C=23,60?2,48 in the descending colon/ PnX=39,92?3,49 and C=44,32?5,56 in the proximal jejunum). However, in chronic group there was an uprising crypt cell production per crypt in the proximal jejunum (PnX=57,54?2,19 and C=47,19?7,3)and in the descending colon (PnX=37,78?2,22 and C=17,92?2,28). CONCLUSION: As the increase of intestinal crypts epithelial cells in chronic group is a carcinogenesis predetermining factor, the understanding of the interaction between pineal gland and this event has great importance.

Revista Brasileira de Zootecnia , 2001, DOI: 10.1590/S1516-35982001000500005
Abstract: this experiment was undertaken to evaluate the effect of dietary tannin on growth performance and carcass composition of piau?u, for sixty days. twenty one aquaria (80 l) were supplied with dechlorinated tap-water (1 l/min) in a closed system. water quality was controled by biologic filter and heater. fish, with inicial average weight 5.06 g, in a triplicate aquaria, were randomly assigned to each of 7 treatments. experimental diets were formulated to contain approximately 3,200 kcal of digestible energy, 30% crude protein and 0.0, 0.23, 0.46, 0.69, 0.92, 1.37 and 1.82% of total tannin. although 0.69% of tannin added did not affected apparent feed conversion and protein efficiency ratio, concentrations equal or higher than 0.46% resulted lower weight gain. piau?u was sensitive to condensed tannin which had significant harmful effect on metabolism and biological value of dietary nutrients.
Desempenho do piau u (Leporinus macrocephalus) arra oado com dietas contendo diferentes teores de tanino
Pinto Luis Gabriel Quintero,Pezzato Luiz Edivaldo,Miranda Edma Carvalho de,Barros Margarida Maria
Revista Brasileira de Zootecnia , 2001,
Abstract: Este estudo foi conduzido com o objetivo de avaliar o efeito dos taninos sobre o desempenho produtivo e a composi o da carca a do piau u. Utilizaram-se 21 aquários (80 L) num sistema de fluxo fechado com circula o continua (vaz o de 1 L/min), filtro biológico e temperatura controlada. Empregaram-se 84 peixes com peso médio inicial de 5,06 g, na densidade de quatro por aquário, num delineamento inteiramente casualizado com sete tratamentos e três repeti es. As ra es foram formuladas de forma a apresentarem-se isoenergéticas (3200 kcal ED/ kg de ra o) e isoprotéicas (30% PB), com as seguintes composi es de tanino total: 0,00; 0,23; 0,46; 0,69; 0,92; 1,37 e 1,82. Avaliou-se a influência do tanino sobre o desempenho produtivo: ganho de peso, convers o alimentar aparente e taxa de eficiência protéica; a composi o corporal dos peixes: proteína bruta da carca a, extrato etéreo da carca a, proteína bruta e extrato etéreo dos fígados e gordura visceral; e a rela o hepatossomática: índice hepatossomático. Concluiu-se que, embora a presen a de até 0,69% de taninos na ra o n o tenha comprometido os índices de convers o alimentar aparente e taxa de eficiência protéica das ra es, níveis iguais ou superiores a 0,46% resultaram em ganho de peso significativamente inferior para o piau u e que a espécie se mostrou sensível à presen a de taninos condensados, os quais prejudicaram significativamente o metabolismo e o valor biológico dos nutrientes presentes nas ra es.

Brazilian Archives of Biology and Technology , 2002,
Abstract: Thirty-two eggs of Pantanal caiman (Caiman crocodilus yacare) (Daudin, 1802) were incubated at 30° C. After 20 days of incubation at 30° C, the remaining eggs were distributed in the following way: seven at 34° C, seven at 32° C, six at 30° C and six at 28° C. At 32° C and 34° C a 100% hatchability was obtained while at 30° C 83.3% and at 28° C 66.6%. After hatching, the animals were kept for 120 days at the same temperature of their final incubation. Weight (g) control and morphometric (cm) analysis were carried out. The statistic design was totally randomized and the data were treated by regression analysis showing a quadratic behavior ( p<0.05). It was found that weight, total length (TTL), tail length (TL), snout- vent length (SVL), head length (HL), eye length (EL), snout length (SL), mid-point snout width (MSW), head width (HW), width of snout at nostrils (NW), distance between limbs (DBL) showed a higher development at the temperature range from 31.2° C to 31.8° C and circumference of belly at 30.0° C.

Abstract: Clostridium difficile is a nosocomial enteric pathogen, considered the main etiological agent of antibiotic-associated diarrhea in hospitals. C. difficile is resistant to several antimicrobial agents used in empiric treatment protocols, which confers selective advantages to this species as compared with other members of the intestinal microbiota. The aim of this study was to evaluate and identify possible alterations of the intestinal microbiota population resulting from the use of antimicrobials associated with infections by C. difficile (CDI). Denaturing Gradient Gel Electrophoresis (DGGE) was used to evaluate fecal samples from two groups: healthy subjects and patients with C. difficile-associated diarrhea (CDAD). A decrease in bacterial diversity was highlighted by the low number of bands in samples from CDAD patients, compared with healthy subjects. This may indicate that antibiotic treatment would affect bacterial diversity, leading to a significant difference between the intestinal microbiota of these two groups, but further studies are still needed. Firmicutes and Verrucomicrobia phyla were detected mainly in healthy individuals, and these could be related to protection factors against the CDI. Klebsiella variicola/K. pneumoniae were found mostly in samples from CDI patients. This study shows the effects of antimicrobials and the CDI itself on human intestinal microbiota.

Abstract: Los implantes dentales han evolucionado de forma sustancial en los últimos 40 a os; sin embargo, dudas sobre las características de la reparación ósea continúan toda vez que nuevos dise os y nuevos métodos quirúrgicos son aplicados. El objetivo de esta investigación es evidenciar la presencia de tejido mineralizado en diferentes regiones del implante. Se elaboró un estudio basado en un modelo de restauración inmediata, aplicado en la mandíbula de 7 canes machos. Se realizaron las exodontias de los premolares mandibulares y, después de 3 meses de recuperación, se instalaron 2 implantes endóseos bilaterales, siendo uno de tipo cónico y otro de tipo cilindrico. Después de dos periodos de sacrificio se realizo una evaluación histomorfométrica en los cortes seleccionados. Los resultados se presentan de forma porcentual estableciendo comparaciones entre las áreas cervical, media y apical. Los implantes de morfología cónica sometidos al modelo de restauración inmediata, presentaron mayor formación ósea en todos los niveles evaluados. En todas las condiciones de trabajo el área cervical presentó mayor presencia de tejido mineralizado que el área apical. Concluimos que el modelo de restauración inmediata no es un obstáculo para la instalación de la secuencia apropiada de reparación ósea y que diferentes factores deben estar asociados a la mayor formación ósea presente en el área cervical de los implantes dentales. Dental implants have evolved of substantial form in the last 40 years; however, doubt about osseous repair characteristic are maintained because new design and surgical method are applied. The aim of this research is show the mineralized tissue in different areas of the implant. Was done a study based to a immediate load model applied in 7 male dogs mandible. Was realized the dental extractions of de bilateral mandibles bicusp and after to 3 month of recuperations was installed two bilaterally implants, been conical and cylindered shape. After of two sacrifices period was realized a histomorphometric analysis in the selection cut. The results are present with perceptual form, establishing cervical, meddle and apical comparison. Conical implants with immediaterestoration model were present more osseous formations in all evaluated level. For all conditions of work, cervical area presented more mineralized tissue than apical area. We conclude that immediately restoration model it is not an obstacle for the installation of the appropriate sequence for the osseous reparation and that different factors have been associated to the more osseous formation in th

Abstract: OBJETIVO:Analisar a mortalidade por diabetes mellitus em idosos e a subenumera o do diabetes como causa do óbito de acordo com estatísticas baseadas unicamente em causa básica de óbito. MéTODOS:Foram revisadas todas as 2.974 declara es de óbito ocorridas em 1994 de idosos residentes em um núcleo habitacional localizado na cidade do Rio de Janeiro, RJ. Destas, foram estudados 291 óbitos, tendo o diabetes mellitus como causa básica (150) e associada (141). A propor o de óbitos em que a diabetes aparece como causa básica em rela o ao total de óbitos por diabetes foi calculada de forma global e segundo sexo e faixa etária. RESULTADOS:Dos 291 óbitos estudados, 138 (47,4%) ocorreram em homens, e 153, em mulheres (52,6%). As taxas de mortalidade apresentaram crescimento contínuo com o avan ar da idade, sendo superiores no sexo masculino, embora a diferen a entre sexos tenha sido menor para a análise baseada unicamente na causa básica. Observou-se propor o elevada de óbitos domiciliares (22%). A propor o de óbitos por diabetes como causa básica foi de 51,5%, sendo maior nas mulheres do que nos homens. CONCLUS ES:A análise das estatísticas de mortalidade baseadas unicamente na causa básica do óbito pode levar a perfis distorcidos, em fun o da subenumera o n o ocorrer aleatoriamente. Estudos adicionais em coortes de idosos brasileiros diabéticos s o necessários para permitir uma avalia o mais acurada da mortalidade nesse grupo.
