The present paper deals with the immobilization of redox mediators and proteins onto protected porous silicon surfaces to obtain their direct electrochemical reactions and to retain their bioactivities. This paper shows that MP-11 and viologens are able to establish chemical bonds with 3-aminopropyltriethoxylsilane-modified porous silicon surface. The functionalization of the surfaces have been fully characterized by energy dispersive X-ray analysis (EDX) and X-ray photoelectron spectroscopy (XPS) to examine the immobilization of these mediators onto the solid surface. Amperometric and open circuit potential measurements have shown the direct electron transfer between glucose oxidase and the electrode in the presence of the viologen mediator covalently linked to the 3-aminopropyltriethoxylsilane (APTES)-modified porous silicon surfaces.

The CRAC assay is a direct electron transfer test of antioxidant capacity for several organic compounds. The ability of eight different compounds in reducing Cc 41 was studied by chronoamperometric measurements of the remaining Ce(3+) species. The following antioxidant classification was observed: tannic acid >> quercetin > rutin > gallic acid approximate to catechin > ascorbic acid > BHA > Trolox. These results agree with others already published and a good correlation (R(2) = 0.937) was found with the classical spectrophotometric FRAP assay. The CRAC assay is simple, fast, free from sample pretreatment and applicable to nontransparent samples.

Background: Established in 1999, the Swedish Maternal Health Care Register (MHCR) collects data on pregnancy, birth, and the postpartum period for most pregnant women in Sweden. Antenatal care (ANC) midwives manually enter data into the Web-application that is designed for MHCR. The aim of this study was to investigate midwives? experiences, opinions and use of the MHCR. Method: A national, cross-sectional, questionnaire survey, addressing all Swedish midwives working in ANC, was conducted January to March 2012. The questionnaire included demographic data, preformed statements with six response options ranging from zero to five (0 = totally disagree and 5 = totally agree), and opportunities to add information or further clarification in the form of free text comments. Parametric and non-parametric methods and logistic regression analyses were applied, and content analysis was used for free text comments. Results: The estimated response rate was 53.1%. Most participants were positive towards the Web-application and the included variables in the MHCR. Midwives exclusively engaged in patient-related work tasks perceived the register as burdensome (70.3%) and 44.2% questioned the benefit of the register. The corresponding figures for midwives also engaged in administrative supervision were 37.8% and 18.5%, respectively. Direct electronic transfer of data from the medical records to the MHCR was emphasised as significant future improvement. In addition, the midwives suggested that new variables of interest should be included in the MHCR ? e.g., infertility, outcomes of previous pregnancy and birth, and complications of the index pregnancy. Conclusions: In general, the MHCR was valued positively, although perceived as burdensome. Direct electronic transfer of data from the medical records to the MHCR is a prioritized issue to facilitate the working situation for midwives. Finally, the data suggest that the MHCR is an underused source for operational planning and quality assessment in local ANC centres.

Nível de renda e estado de saúde são variáveis correlacionadas tanto pelo fato de aumentos da primeira propiciarem maior acesso a bens e serviços que se refletem em melborias no estado de saúde das pessoas, como pelos ganhos de produtividade e de renda propiciadas por melborias da saúde do trabalhador. Esse artigo estuda os impactos da renda na saúde no Brasil, tendo como instrtrnlento para lidar com o problema de simultaneidade, as mudanças observadas em políticas de transferência de renda aos idosos de baixa renda. A estratégia usada foi comparar o estado de saúde de pessoas idosas de baixa renda - sem contar o efeito dos benefícios - antes e depois do incremento exógeno do recebimento de novos programas de transferência de renda. Utilizamos um estimador de diferenças em diferenças baseado em regressões logísticas. Os dados foram extraídos de suplementos especiais de saúde de pesquisas domiciliares do IBGE (PNAD 1998 e 2003). O trabalbo demonstra uma melbora diferenciada do estado de saúde de pessoas idosas de baixa renda

This paper examines value created through spinoffs over a period from 2002-2010. The net debt to average share price ratio and the debt to asset ratio of a company impacts the decision for this restructuring process statistically significant. The announcement of a spinoff yields abnormal returns (AR) for the stockholders of the parent. The relative size of the spin and the financial leverage correlated with the AR positively, whereas the net debt per share and the return on asset negatively. Therefore, no direct wealth transfer from the debt holders of a company to the equity holders can be derived from these results.

A taxa de desemprego no Brasil sofreu redução significativa do começo do século XXI até o fim do ano de 2014. No entanto, esta redução significativa não foi acompanhada do esperado crescimento econômico disposto na teoria. Desta forma, constata-se que embora a taxa de desemprego tenha se reduzido, não necessariamente as pessoas estavam trabalhando e produzindo. Procurará se entender os fatores que influenciaram esta trajetória de redução da taxa de desemprego por meio de influência na PEA e no número de admissões de empregados, que aproximaremos à oferta e à demanda por mão de obra. Ou seja, pretende-se verificar as variáveis que influenciaram uma possível redução da oferta de trabalho, assim como uma maior demanda por trabalho, resultantes em uma redução da taxa de desemprego. Serão consideradas variáveis de renda, de transferência de renda, de educação e de crescimento econômico na análise das influências da baixa taxa de desemprego. Com base em um modelo vetor de correção de erros (VEC) pretende-se identificar quais variáveis efetivamente afetaram o panorama do desemprego.

Apesar de uma Constituição carregada de direitos sociais visando à transformação da sociedade brasileira, foi somente a partir de 2003 que o país ganhou destaque internacional nas ações de combate à pobreza e desigualdade, tornando-se uma referência. O grande protagonista teria sido o Programa Bolsa Família (PBF), um programa de transferência de renda condicionada que, combinado aos direitos sociais, teria permitido o alívio imediato de situações de extrema pobreza, mas também o desenvolvimento do capital humano atingindo resultados positivos multidimensionais nos seus mais de 10 anos de existência. Tal processo iniciou um debate acerca da necessidade de institucionalizar o programa como uma política de Estado, que para alguns interlocutores significaria transformar o PBF em um “direito” aos moldes dos direitos sociais, impondo uma obrigação aos governos futuros. Diante disso, este trabalho busca identificar, do ponto de vista jurídico e comparado aos direitos sociais, quais as vantagens e desvantagens do PBF na sua configuração atual. Compondo o movimento que busca compreender o papel do direito nas políticas públicas, adotando uma abordagem intra e interdisciplinar, e uma perspectiva funcional; a reflexão é alicerçada em três “eixos”: a cidadania, a judicialização e a vinculação orçamentária. Esse “tripé” foi escolhido em função da estrutura constitucional acerca dos direitos sociais, que em uma leitura funcional representam uma obrigação de fazer ao Estado para a concretização de uma noção de cidadania abrangente; uma dotação orçamentária vinculativa, garantido que parte da receita será destinada a ações de cumprimento dessas obrigações; e os instrumentos para adjudicação, permitindo a exigência dessas ações estatais pelos cidadãos. Assim, este trabalho não buscar descrever ou tentar prescrever a natureza ou alcance das obrigações que a transformação do PBF em direito geraria ao Estado; mas sim refletir sobre as vantagens e desvantagens dessa eventual mudança do programa diante das características estruturais do país, do modelo de sociedade abstratamente desenhado na lei maior e de nossa cultura jurídica acerca dos direitos sociais.

This study aims to analyze the main effect of social programs and cash transfers on the labor supply of non-farm family members in poverty in rural areas of the Northeast. Among the specific objectives, we sought to investigate the effects of these programs and individual characteristics on the decision of participation and allocation of working hours of parents and children in non-agricultural activities. It was assumed, as a theoretical basis, the model of neoclassical labor supply as well as the principle that the decision of allocation of working hours, non-agricultural, is subject to the initial choice of the worker devote or not the non-agricultural employment . The hypothesis assumes that access to social programs and income transfer contributes to the dismay of rural workers, in poverty, in its decision to participate and offer hours of work in non-agricultural activities. To achieve this objective, we applied the models of Heckman (1979) and Double Hurdle, of Cragg (1971), consisting of associating the decision to participate in the labor market with the decision on the amount of hours allocated. The database used was the National Survey by Household Sampling (PNAD) of 2006. The results of the heads of households showed that transfers of income, although they may have some effect on labor supply rural nonfarm, the magnitude has to say that there may be some dependence on benefits. The estimates for the joint children of 10 to 15 years showed that the programs have negatively influenced participation in suggesting an increase in school participation, although for the allocation of working hours the results were not significant on the incidence of child labor

This study aims to the evaluate the determinants for rural households northeastern be pluriactive, in 2011. For this, at first, we conducted a review of national and international literature in order to get beyond the theoretical part which refers to the study of pluriactivity identify possible determinants of the phenomenon. In this rescue, it was the observed determinants could be macroeconomic in nature and / or microeconomics. Therefore, it became necessary to describe the characteristics of the region under study, the Northeast. In order to identify the determinants were two estimated Probit models, one based on the literature review and the second with a variable characteristic of the Northeast, the transfers. For this, we used the PNAD in 2011. The results indicate both the microeconomic determinants are : gender, race, age, years of education, hours worked, number of family members, per capita income, transfer the macroeconomic in nature: living conditions (water, energy, sanitation ), housing location. In addition to identifying the determinants, the Econometric model allows to know the probability of each variable on the dependent variable, which stood out: the transfer variable, gender, per capita income, number of family members, housing conditions and housing location. Therefore, it is concluded that it is the set of determinants (macro and micro) allow rural families become northeastern pluriactive. However, one can not fail to consider may also have other determinants were not captured due to the availability of data, which may be indications for future studies. In summary, the pluriactivity in the Brazilian Northeast is a phenomenon distinct from found in Europe and southern Brazil. It is a pluriactivity survival that is part of the strategies of rural households in the Northeast to ensure their social reproduction amid the poverty of the region

Os programas comerciais de transferência de embriões em éguas existem por mais de três décadas e são hoje uma das biotécnias mais utilizadas na reprodução assistida de equinos. O exame ultrassonográfico nos períodos pré e pós-cobertura de doadoras de embriões, assim como a avaliação de receptoras no momento da inovulação é de vital importância para o êxito de um programa de transferência de embriões. A ultrassonografia Doppler é uma técnica não-invasiva que permite a avaliação em tempo real da hemodinâmica do trato reprodutivo de animais de grande porte. Por fornecer detalhes anatômicos e informações imediatas sobre a fisiologia do fluxo sanguíneo de tecidos e órgãos, o exame doppler permite a avaliação do potencial ovulatório de folículos e do status funcional de corpo lúteo e útero, além de ser uma técnica auxiliar para o diagnóstico de distúrbios na hemodinâmica do sistema reprodutivo. Alterações na perfusão sanguínea dos futuros folículos dominantes são detectáveis em diferentes fases de seu desenvolvimento, como na divergência folicular e no período pré-ovulatório. A partir dessas informações, é possível determinar o princípio da atividade sexual e o momento ideal para o início de tratamentos superovulatórios e indutores de ovulação, assim como o momento mais apropriado para a realização de coberturas de éguas doadoras de embriões. A avaliação através do modo-Doppler do corpo lúteo e útero de éguas receptoras é também um instrumento auxiliar para a seleção de animais com perfil sérico de progesterona e ambiente uterino adequados para a sobrevivência do embrião e manutenção da gestação. Essa técnica pode ser útil ainda ao se avaliar a interação concepto-maternal. Apesar da aplicabilidade da tecnologia doppler dentro de programas de transferência de embriões, novos estudos visando a determinar padrões de normalidade e posterior caracterização de distúrbios de fluxo sanguíneo de trato reprodutivo ainda se fazem necessários.

Superovulation would potentially increase the efficiency and decrease the cost of embryo transfer by increasing embryo collection rates. Other potential clinical applications include improving pregnancy rates from frozen semen, treatment of subfertility in stallions and mares, and induction of ovulation in transitional mares. The objective of this study was to evaluate the efficacy of purified equine follicle stimulating hormone (eFSH; Bioniche Animal Health USA, Inc., Athens, GA) in inducing superovulation in cycling mares. In the first experiment, 49 normal, cycling mares were used in a study at Colorado State University. Mares were assigned to 1 of 3 groups: group 1, controls (n = 29) and groups 2 and 3, eFSH-treated (n = 10/group). Treated mares were administered 25 mg of eFSH twice daily beginning 5 or 6 days after ovulation (group 2). Mares received 250 (of cloprostenol on the second day of eFSH treatment. Administration of eFSH continued until the majority of follicles reached a diameter of 35 mm, at which time a deslorelin implant was administered. Group 3 mares (n = 10) received 12 mg of eFSH twice daily starting on day 5 or 6. The treatment regimen was identical to that of group 2. Mares in all 3 groups were bred with semen from 1 of 4 stallions. Pregnancy status was determined at 14 to 16 days after ovulation. In experiment 2, 16 light-horse mares were used during the physiologic breeding season in Brazil. On the first cycle, mares served as controls, and on the second cycle, mares were administered 12 mg of eFSH twice daily until a majority of follicles were 35 mm in diameter, at which time human chorionic gonadotropin (hCG) was administered. Mares were inseminated on both cycles, and embryo collection attempts were performed 7 or 8 days after ovulation. Mares treated with 25 mg of eFSH developed a greater number of follicles (35 mm) and ovulated a greater number of follicles than control mares. However, the number of pregnancies obtained per mare was not different between control mares and those receiving 25 mg of eFSH twice daily. Mares treated with 12 mg of eFSH and administered either hCG or deslorelin also developed more follicles than untreated controls. Mares receiving eFSH followed by hCG ovulated a greater number of follicles than control mares, whereas the number of ovulations from mares receiving eFSH followed by deslorelin was similar to that of control mares. Pregnancy rate for mares induced to ovulate with hCG was higher than that of control mares, whereas the pregnancy rate for eFSH-treated mares induced to ovulate with deslorelin did not differ from that of the controls. Overall, 80% of mares administered eFSH had multiple ovulations compared with 10.3% of the control mares. In experiment 2, the number of large follicles was greater in the eFSH-treated cycle than the previous untreated cycle. In addition, the number of ovulations during the cycle in which mares were treated with eFSH was greater (3.6) than for the control cycle (1.0). The average number of embryos recovered per mare for the eFSH cycle (1.9 ± 0.3) was greater than the embryo recovery rate for the control cycle (0.5 ± 0.3). In summary, the highest ovulation and the highest pregnancy and embryo recovery rates were obtained after administration of 12 mg of eFSH twice daily followed by 2500 IU of hCG. Superovulation with eFSH increased pregnancy rate and embryo recovery rate and, thus, the efficiency of the embryo transfer program.
